12006-04-01 Paul D. Smith <psmith@gnu.org> 2 3 Version 3.81 released. 4 5 * NEWS: Updated for 3.81. 6 7 * README.cvs: Mention that vpath builds are not supported out of 8 CVS. Fixes Savannah bug #16236. 9 Remove update of make.texi from the list of things to do; we use 10 version.texi now. 11 122006-03-26 Paul D. Smith <psmith@gnu.org> 13 14 * doc/make.texi: Clean up licensing. Use @copying and version.texi 15 support from automake, as described in the Texinfo manual. 16 172006-03-25 Eli Zaretskii <eliz@gnu.org> 18 19 * implicit.c (pattern_search) [HAVE_DOS_PATHS]: Don't compare b 20 with lastslash, since the latter points to filename, not to 21 target. 22 * job.c (construct_command_argv_internal) [HAVE_DOS_PATHS]: 23 Declare and define sh_chars_sh[]. 24 252006-03-23 Paul D. Smith <psmith@gnu.org> 26 27 * configure.in: Look for build.sh.in in $srcdir so it will be 28 built for remote configurations as well. 29 30 * Makefile.am: Make sure to clean up build.sh during distclean. 31 Fixes Savannah bug #16166. 32 33 * misc.c (log_access): Takes a const char *. 34 * function.c (fold_newlines): Takes an unsigned int *. 35 Both fixes for Savannah bug #16170. 36 372006-03-22 Boris Kolpackov <boris@kolpackov.net> 38 39 * implicit.c (pattern_search): Call set_file_variables only 40 if we have prerequisites that need second expansion. Fixes 41 Savannah bug #16140. 42 432006-03-19 Paul D. Smith <psmith@gnu.org> 44 45 * remake.c (update_file): Add alloca(0) to clean up alloca'd 46 memory on hosts that don't support it directly. 47 48 * README.cvs: Add information on steps for making a release (to 49 make sure I don't forget any). 50 51 * main.c (clean_jobserver): Move jobserver cleanup code into a new 52 function. 53 (die): Cleanup code was removed from here; call the new function. 54 (main): If we are re-execing, clean up the jobserver first so we 55 don't leak file descriptors. 56 Fix bug reported by Craig Fithian <craig.fithian@citigroup.com>. 57 582006-03-17 Paul D. Smith <psmith@gnu.org> 59 60 * maintMakefile (do-po-update): Rewrite this rule to clean up and 61 allow multiple concurrent runs. 62 Patch from Joseph Myers <joseph@codesourcery.com> 63 642006-03-17 Boris Kolpackov <boris@kolpackov.net> 65 66 * dep.h (struct dep): Add the stem field. 67 * misc.c (alloc_dep, free_dep): New functions. 68 (copy_dep_chain): Copy stem. 69 (free_dep_chain): Use free_dep. 70 * read.c (record_files): Store stem in the dependency line. 71 * file.c (expand_deps): Use stem stored in the dependency line. Use 72 free_dep_chain instead of free_ns_chain. 73 * implicit.c (pattern_search): Use alloc_dep and free_dep. 74 * read.c (read_all_makefiles, eval_makefile, eval): Ditto. 75 * main.c (main, handle_non_switch_argument): Ditto. 76 * remake.c (check_dep): Ditto. 77 * rule.c (convert_suffix_rule, freerule): Ditto. 78 792006-03-14 Paul D. Smith <psmith@gnu.org> 80 81 * expand.c (variable_append): Instead of appending everything then 82 expanding the result, we expand (or not, if it's simple) each part 83 as we add it. 84 (allocated_variable_append): Don't expand the final result. 85 Fixes Savannah bug #15913. 86 872006-03-09 Paul Smith <psmith@gnu.org> 88 89 * remake.c (update_file_1): Revert the change of 3 Jan 2006 which 90 listed non-existent files as changed. Turns out there's a bug in 91 the Linux kernel builds which means that this change causes 92 everything to rebuild every time. We will re-introduce this fix 93 in the next release, to give them time to fix their build system. 94 Fixes Savannah bug #16002. 95 Introduces Savannah bug #16051. 96 97 * implicit.c (pattern_search) [DOS_PATHS]: Look for DOS paths if 98 we *don't* find UNIX "/". 99 Reported by David Ergo <david.ergo@alterface.com> 100 1012006-03-04 Eli Zaretskii <eliz@gnu.org> 102 103 * variable.c (do_variable_definition) [WINDOWS32]: Call the shell 104 locator function find_and_set_default_shell if SHELL came from the 105 command line. 106 1072006-02-20 Paul D. Smith <psmith@gnu.org> 108 109 * variable.c (merge_variable_set_lists): It's legal for *setlist0 110 to be null; don't core in that case. 111 1122006-02-19 Paul D. Smith <psmith@gnu.org> 113 114 * commands.c (set_file_variables): Realloc, not malloc, the static 115 string values to avoid memory leaks. 116 117 * expand.c (recursively_expand_for_file): Only set reading_file to 118 an initialized value. 119 120 * implicit.c (pattern_search): We need to make a copy of the stem 121 if we get it from an intermediate dep, since those get freed. 122 123 * file.c (lookup_file) [VMS]: Don't lowercase special targets that 124 begin with ".". 125 (enter_file) [VMS]: Ditto. 126 Patch provided by Hartmut Becker <Hartmut.Becker@hp.com>. 127 1282006-02-24 Eli Zaretskii <eliz@gnu.org> 129 130 * job.c (construct_command_argv_internal): Fix last change. 131 132 * w32/subproc/sub_proc.c (process_pipe_io): Make dwStdin, 133 dwStdout, and dwStderr unsigned int: avoids compiler warnings in 134 the calls to _beginthreadex. 135 136 * expand.c (recursively_expand_for_file): Initialize `save' to 137 prevent compiler warnings. 138 1392006-02-18 Eli Zaretskii <eliz@gnu.org> 140 141 * job.c (construct_command_argv_internal): Don't create a temporary 142 script/batch file if we are under -n. Call _setmode to switch the 143 script file stream to text mode. 144 1452006-02-17 Paul D. Smith <psmith@gnu.org> 146 147 * variable.c (merge_variable_set_lists): Don't try to merge the 148 global_setlist. Not only is this useless, but it can lead to 149 circularities in the linked list, if global_setlist->next in one 150 list gets set to point to another list which also ends in 151 global_setlist. 152 Fixes Savannah bug #15757. 153 1542006-02-15 Paul D. Smith <psmith@gnu.org> 155 156 Fix for Savannah bug #106. 157 158 * expand.c (expanding_var): Keep track of which variable we're 159 expanding. If no variable is being expanded, it's the same as 160 reading_file. 161 * make.h (expanding_var): Declare it. 162 * expand.c (recursively_expand_for_file): Set expanding_var to the 163 current variable we're expanding, unless there's no file info in 164 it (could happen if it comes from the command line or a default 165 variable). Restore it before we exit. 166 * expand.c (variable_expand_string): Use the expanding_var file 167 info instead of the reading_file info. 168 * function.c (check_numeric): Ditto. 169 (func_word): Ditto. 170 (func_wordlist): Ditto. 171 (func_error): Ditto. 172 (expand_builtin_function): Ditto. 173 (handle_function): Ditto. 174 1752006-02-14 Paul D. Smith <psmith@gnu.org> 176 177 * read.c (eval): Even if the included filenames expands to the 178 empty string we still need to free the allocated buffer. 179 180 * implicit.c (pattern_search): If we allocated a variable set for 181 an impossible file, free it. 182 * variable.c (free_variable_set): New function. 183 * variable.h: Declare it. 184 185 * read.c (read_all_makefiles): Makefile names are kept in the 186 strcache, so there's never any need to alloc/free them. 187 (eval): Ditto. 188 189 * main.c (main): Add "archives" to the .FEATURES variable if 190 archive support is enabled. 191 * doc/make.texi (Special Variables): Document it. 192 1932006-02-13 Paul D. Smith <psmith@gnu.org> 194 195 * implicit.c (pattern_search): Add checking for DOS pathnames to 196 the pattern rule target LASTSLASH manipulation. 197 Fixes Savannah bug #11183. 198 1992006-02-11 Paul D. Smith <psmith@gnu.org> 200 201 * (ALL FILES): Updated copyright and license notices. 202 2032006-02-10 Paul D. Smith <psmith@gnu.org> 204 205 A new internal capability: the string cache is a read-only cache 206 of strings, with a hash table interface for fast lookup. Nothing 207 in the cache will ever be freed, so there's no need for reference 208 counting, etc. This is the beginning of a full solution for 209 Savannah bug #15182, but for now we only store makefile names here. 210 211 * strcache.c: New file. Implement a read-only string cache. 212 * make.h: Add prototypes for new functions. 213 * main.c (initialize_global_hash_tables): Initialize the string cache. 214 (print_data_base): Print string cache stats. 215 * read.c (eval_makefile): Use the string cache to store makefile 216 names. Rewrite the string allocation to be sure we free everything. 217 2182006-02-10 Eli Zaretskii <eliz@gnu.org> 219 220 * dir.c (dir_contents_file_exists_p): Don't opendir if the 221 directory time stamp didn't change, except on FAT filesystems. 222 Suggested by J. David Bryan <jdbryan@acm.org>. 223 2242006-02-09 Paul D. Smith <psmith@gnu.org> 225 226 * function.c (func_or): Implement a short-circuiting OR function. 227 (func_and): Implement a short-circuiting AND function. 228 (function_table_init): Update the table with the new functions. 229 * doc/make.texi (Conditional Functions): Changed the "if" section 230 to one on general conditional functions. Added documentation for 231 $(and ...) and $(or ...) functions. 232 * NEWS: Note new $(and ...) and $(or ...) functions. 233 2342006-02-08 Boris Kolpackov <boris@kolpackov.net> 235 236 * job.h (struct child): Add the dontcare bitfield. 237 * job.c (new_job): Cache dontcare flag. 238 * job.c (reap_children): Use cached dontcare flag instead of the 239 one in struct file. Fixes Savannah bug #15641. 240 2412006-02-06 Paul D. Smith <psmith@gnu.org> 242 243 * vpath.c (selective_vpath_search): If the file we find has a 244 timestamp from -o or -W, use that instead of the real time. 245 * remake.c (f_mtime): If the mtime is a special token from -o or 246 -W, don't overwrite it with the real mtime. 247 Fixes Savannah bug #15341. 248 249 Updates from Markus Mauhart <qwe123@chello.at>: 250 251 * w32/subproc/sub_proc.c (process_begin): Remove no-op tests. 252 (process_signal, process_last_err, process_exit_code): Manage 253 invalid handle values. 254 (process_{outbuf,errbuf,outcnt,errcnt,pipes}): Unused and don't 255 manage invalid handles; remove them. 256 * job.c (start_job_command) [WINDOWS32]: Jump out on error. 257 * config.h.W32.template [WINDOWS32]: Set flags for Windows builds. 258 * README.cvs: Updates for building from CVS. 259 2602006-02-05 Paul D. Smith <psmith@gnu.org> 261 262 * file.c (enter_file): Keep track of the last double_colon entry, 263 to avoid walking the list every time we want to add a new one. 264 Fixes Savannah bug #15533. 265 * filedef.h (struct file): Add a new LAST pointer. 266 267 * dir.c (directory_contents_hash_cmp): Don't use subtraction to do 268 the comparison. For 64-bits systems the result of the subtraction 269 might not fit into an int. Use comparison instead. 270 Fixes Savannah bug #15534. 271 272 * doc/make.texi: Update the chapter on writing commands to reflect 273 the changes made in 3.81 for backslash/newline and SHELL handling. 274 2752006-02-01 Paul D. Smith <psmith@gnu.org> 276 277 * dir.c (dir_contents_file_exists_p) [WINDOWS32]: Make sure 278 variable st is not used when it's not initialized. 279 Patch from Eli Zaretskii <eliz@gnu.org>. 280 2812006-01-31 Paul D. Smith <psmith@gnu.org> 282 283 * README.W32.template: Applied patch #4785 from 284 Markus Mauhart <qwe123@chello.at>. 285 * README.cvs: Applied patch #4786 from 286 Markus Mauhart <qwe123@chello.at>. 287 * make_msvc_net2003.vcproj [WINDOWS32]: New version from 288 J. Grant <jg@jguk.org>. 289 290 * main.c: Update the copyright year in the version output. 291 * prepare_w32.bat: Remove this file from the distribution. 292 2932006-01-21 Eli Zaretskii <eliz@gnu.org> 294 295 * remake.c (update_goal_chain): Set g->changed instead of 296 incrementing it, as it is only 8-bit wide, and could overflow if 297 many commands got started in update_file. 298 299 * w32/include/sub_proc.h: Add a prototype for process_used_slots. 300 301 * w32/subproc/sub_proc.c: Change dimension of proc_array[] to 302 MAXIMUM_WAIT_OBJECTS. 303 (process_wait_for_any_private): Change dimension of handles[] 304 array to MAXIMUM_WAIT_OBJECTS. 305 (process_used_slots): New function. 306 (process_register): Don't register more processes than the 307 available number of slots. 308 (process_easy): Don't start new processes if all slots are used up. 309 310 * job.c (load_too_high, start_waiting_jobs) [WINDOWS32]: If there 311 are already more children than sub_proc.c can handle, behave as if 312 the load were too high. 313 (start_job_command): Fix a typo in error message when process_easy 314 fails. 315 3162006-01-14 Eli Zaretskii <eliz@gnu.org> 317 318 * main.c (main) [WINDOWS32]: Don't refuse to run with -jN, even if 319 the shell is not sh.exe. 320 321 * job.c (create_batch_file): Renamed from create_batch_filename; 322 all callers changed. Don't close the temporary file; return its 323 file descriptor instead. New arg FD allows to return the file 324 descriptor. 325 (construct_command_argv_internal): Use _fdopen instead of fopen to 326 open the batch file. 327 3282006-01-04 Paul D. Smith <psmith@gnu.org> 329 330 * readme.vms: Updates for case-insensitive VMS file systems from 331 Hartmut Becker <Hartmut.Becker@hp.com>. 332 * dir.c (vms_hash): Ditto. 333 * vmsify.c (copyto): Ditto. 334 * vmsfunctions.c (readdir): Ditto. 335 336 * make.1: Add a section on the exit codes for make. 337 338 * doc/make.texi: A number of minor updates to the documentation. 339 3402006-01-03 Paul D. Smith <psmith@gnu.org> 341 342 * remake.c (update_file_1): Mark a prerequisite changed if it 343 doesn't exist. 344 345 * read.c (eval): Be sure to strip off trailing whitespace from the 346 prerequisites list properly. Also, initialize all fields in 347 struct dep when creating a new one. 348 3492005-12-28 Paul D. Smith <psmith@gnu.org> 350 351 * config.h.W32.template [WINDOWS32]: Add in some pragmas to 352 disable warnings for MSC. 353 Patch by Rob Tulloh <rtulloh@yahoo.com>. 354 3552005-12-17 Eli Zaretskii <eliz@gnu.org> 356 357 * doc/make.texi (Execution): Add a footnote about changes in 358 handling of backslash-newline sequences. Mention the differences 359 on MS-DOS and MS-Windows. 360 361 * NEWS: More details about building the MinGW port and a pointer 362 to README.W32. Fix the section name that describes the new 363 backward-incompatible processing of backslash-newline sequences. 364 The special processing of SHELL set to "cmd" is only relevant to 365 MS-Windows, not MS-DOS. 366 3672005-12-17 Eli Zaretskii <eliz@gnu.org> 368 369 * main.c (handle_runtime_exceptions): Cast exrec->ExceptionAddress 370 to DWORD, to avoid compiler warnings. 371 * job.c (exec_command): Cast hWaitPID and hPID to DWORD, and 372 use %ld in format, to avoid compiler warnings. 373 374 * doc/make.texi (Special Targets): Fix a typo. 375 (Appending): Fix cross-reference to Setting. 376 (Special Variables, Secondary Expansion, File Name Functions) 377 (Flavor Function, Pattern Match, Quick Reference): Ensure two 378 periods after a sentence. 379 (Execution): Add @: after "e.g.". 380 (Environment): Fix punctuation. 381 (Target-specific, Call Function, Quick Reference): Add @: after "etc." 382 (Shell Function, Target-specific): Add @: after "vs." 383 3842005-12-14 Boris Kolpackov <boris@kolpackov.net> 385 386 * read.c (record_target_var): Initialize variable's export field 387 with v_default instead of leaving it "initialized" by whatever 388 garbage happened to be on the heap. 389 3902005-12-12 Paul D. Smith <psmith@gnu.org> 391 392 * make.1: Fix some display errors and document all existing options. 393 Patch provided by Mike Frysinger <vapier@gentoo.org>. 394 3952005-12-11 Paul D. Smith <psmith@gnu.org> 396 397 * implicit.c (pattern_search): If 2nd expansion is not set for 398 this implicit rule, replace the pattern with the stem directly, 399 and don't re-expand the variable list. Along with the other 400 .SECONDEXPANSION changes below, fixes bug #13781. 401 4022005-12-09 Boris Kolpackov <boris@kolpackov.net> 403 404 * implicit.c (pattern_search): Mark other files that this rule 405 builds as targets so that they are not treated as intermediates 406 by the pattern rule search algorithm. Fixes bug #13022. 407 4082005-12-07 Boris Kolpackov <boris@kolpackov.net> 409 410 * remake.c (notice_finished_file): Propagate the change of 411 modification time to all the double-colon entries only if 412 it is the last one to be updated. Fixes bug #14334. 413 4142005-11-17 Boris Kolpackov <boris@kolpackov.net> 415 416 * function.c (func_flavor): Implement the flavor function which 417 returns the flavor of a variable. 418 * doc/make.texi (Functions for Transforming Text): Document it. 419 * NEWS: Add it to the list of new functions. 420 4212005-11-14 Boris Kolpackov <boris@kolpackov.net> 422 423 * read.c (construct_include_path): Set the .INCLUDE_DIRS special 424 variable. 425 * doc/make.texi (Special Variables): Document .INCLUDE_DIRS. 426 * NEWS: Add .INCLUDE_DIRS to the list of new special variables. 427 4282005-10-26 Paul Smith <psmith@gnu.org> 429 430 * read.c (record_files): Don't set deps flags if there are no deps. 431 * maintMakefile: We only need to build the templates when we are 432 creating a distribution, so don't do it for "all". 433 4342005-10-24 Paul D. Smith <psmith@gnu.org> 435 436 Make secondary expansion optional: its enabled by declaring the 437 special target .SECONDEXPANSION. 438 439 * NEWS: Update information on second expansion capabilities. 440 * doc/make.texi (Secondary Expansion): Document the 441 .SECONDEXPANSION special target and its behavior. 442 * dep.h (struct dep): Add a flag STATICPATTERN, set to true if the 443 prerequisite list was found in a static pattern rule. 444 (free_dep_chain): Declare a prototype. 445 * file.c (parse_prereqs): New function: break out some complexity 446 from expand_deps(). 447 (expand_deps): If we aren't doing second expansion, replace % with 448 the stem for static pattern rules. Call the new function. 449 * filedef.h (parse_prereqs): Declare a prototype. 450 * implicit.c (pattern_search): Initialize the new staticpattern 451 field. 452 * main.c (second_expansion): Declare a global variable to remember 453 if the special target has been seen. Initialize the new 454 staticpattern field for prerequisites. 455 * make.h: Extern for second_expansion. 456 * misc.c (free_dep_chain): New function: frees a struct dep list. 457 * read.c (read_all_makefiles): Initialize the staticpattern field. 458 (eval_makefile): Ditto. 459 (record_files): Check for the .SECONDEXPANSION target and set 460 second_expansion global if it's found. 461 Use the new free_dep_chain() instead of doing it by hand. 462 Set the staticpattern field for prereqs of static pattern targets. 463 4642005-10-16 Paul D. Smith <psmith@gnu.org> 465 466 * main.c (main): Set CURDIR to be a file variable instead of a 467 default, so that values of CURDIR inherited from the environment 468 won't override the make value. 469 4702005-09-26 Paul D. Smith <psmith@gnu.org> 471 472 * job.c (construct_command_argv_internal): If the line is empty 473 remember to free the temporary argv strings. 474 Fixes bug # 14527. 475 4762005-09-16 Paul D. Smith <psmith@gnu.org> 477 478 * job.c (start_job_command): The noerror flag is a boolean (single 479 bit); set it appropriately. 480 Reported by Mark Eichin <eichin@metacarta.com> 481 4822005-08-29 Paul D. Smith <psmith@gnu.org> 483 484 * function.c (func_error): On Windows, output from $(info ...) 485 seems to come in the wrong order. Try to force it with fflush(). 486 4872005-08-10 Boris Kolpackov <boris@kolpackov.net> 488 489 * read.c (record_files): Move code that sets stem for static 490 pattern rules out of the if (!two_colon) condition so it is 491 also executed for two-colon rules. Fixes Savannah bug #13881. 492 4932005-08-08 Paul D. Smith <psmith@gnu.org> 494 495 * make.h: Don't test that __STDC__ is non-0. Some compilers 496 (Windows for example) set it to 0 to denote "ISO C + extensions". 497 Fixes bug # 13594. 498 4992005-08-07 Paul D. Smith <psmith@gnu.org> 500 501 * w32/pathstuff.c (getcwd_fs): Fix warning about assignment in a 502 conditional (slightly different version of a fix from Eli). 503 504 Fix a bug reported by Michael Matz <matz@suse.de>: patch included. 505 If make is running in parallel without -k and two jobs die in a 506 row, but not too close to each other, then make will quit without 507 waiting for the rest of the jobs to die. 508 509 * main.c (die): Don't reset err before calling reap_children() the 510 second time: we still want it to be in the error condition. 511 * job.c (reap_children): Use a static variable, rather than err, 512 to control whether or not the error message should be printed. 513 5142005-08-06 Eli Zaretskii <eliz@gnu.org> 515 516 * w32/subproc/sub_proc.c: Include signal.h. 517 (process_pipe_io, process_file_io): Pass a pointer to a local 518 DWORD variable to GetExitCodeProcess. If the exit code is 519 CONTROL_C_EXIT, put SIGINT into pproc->signal. 520 521 * job.c [WINDOWS32]: Include windows.h. 522 (main_thread) [WINDOWS32]: New global variable. 523 (reap_children) [WINDOWS32]: Get the handle for the main thread 524 and store it in main_thread. 525 526 * commands.c [WINDOWS32]: Include windows.h and w32err.h. 527 (fatal_error_signal) [WINDOWS32]: Suspend the main thread before 528 doing anything else. When we are done, close the main thread 529 handle and exit with status 130. 530 5312005-07-30 Eli Zaretskii <eliz@gnu.org> 532 533 * w32/subproc/sub_proc.c (process_begin): Don't pass a NULL 534 pointer to fprintf. 535 536 * main.c (find_and_set_default_shell): If found a DOSish shell, 537 set sh_found and the value of default_shell, and report the 538 findings in debug mode. 539 540 * job.c (construct_command_argv_internal): Check unixy_shell, not 541 no_default_sh_exe, to decide whether to use Unixy or DOSish 542 builtin commands. 543 544 * README.W32: Update with info about the MinGW build. 545 546 * build_w32.bat: Support MinGW. 547 548 * w32/subproc/build.bat: Likewise. 549 550 * w32/subproc/sub_proc.c (process_easy): Fix format strings for 551 printing DWORD args. 552 553 * function.c (windows32_openpipe): Fix format strings for printing 554 DWORD args. 555 556 * job.c (reap_children) [WINDOWS32]: Don't declare 'status' and 557 'reap_mode'. 558 (start_job_command): Fix format string for printing the result of 559 process_easy. 560 (start_job_command) [WINDOWS32]: Do not define. 561 (exec_command): Fix format string for printing HANDLE args. 562 563 * main.c (handle_runtime_exceptions): Fix sprintf format strings 564 to avoid compiler warnings. 565 (open_tmpfile): Declare fd only if HAVE_FDOPEN is defined. 566 (Note: some of these fixes were submitted independently by J. Grant) 567 5682005-07-30 J. Grant <jg@jguk.org> 569 570 * prepare_w32.bat: Copy config.h.w32 to config.h if not exist. 571 * make_msvc_net2003.vcproj, make_msvc_net2003.sln: MSVC Project files. 572 * Makefile.am (EXTRA_DIST): Add MSVC Project files. 573 5742005-07-15 Paul Smith <psmith@gnu.org> 575 576 * job.c (construct_command_argv_internal) [DOS,WINDOWS32,OS/2]: If 577 we don't have a POSIX shell, then revert to the old 578 backslash-newline behavior (where they are stripped). 579 Fixes bug #13665. 580 5812005-07-08 Paul D. Smith <psmith@gnu.org> 582 583 * config.h.W32.template: Reorder to match the standard config.h, 584 for easier comparisons. 585 From J. Grant <jg@jguk.org> 586 587 * maintMakefile: Remove .dep_segment before overwriting it, in 588 case it's not writable or noclobber is set. 589 * expand.c (variable_expand_string): Cast result of pointer 590 arithmetic to avoid a warning. 591 * main.c (switches): Add full-fledged final initializer. 592 5932005-07-06 Paul D. Smith <psmith@gnu.org> 594 595 * configure.in: IRIX has _sys_siglist. Tru64 UNIX has __sys_siglist. 596 * signame.c (strsignal): If we found _sys_siglist[] or 597 __sys_siglist[] use those instead of sys_siglist[]. 598 From Albert Chin <china@thewrittenword.com> 599 6002005-07-04 Paul D. Smith <psmith@gnu.org> 601 602 * config.h-vms.template [VMS]: Latest VMS has its own glob() and 603 globfree(); set up to use the GNU versions. 604 From Martin Zinser <zinser@zinser.no-ip.info> 605 6062005-07-03 Paul D. Smith <psmith@gnu.org> 607 608 From J. Grant <jg@jguk.org>: 609 610 * README.W32.template: Update the Windows and tested MSVC versions. 611 * NMakefile.template (CFLAGS_any): Change warning level from W3 to W4. 612 * w32/subproc/NMakefile (CFLAGS_any): Ditto. 613 * build_w32.bat: Ditto. 614 * w32/subproc/build.bat: Ditto. 615 6162005-06-28 Paul D. Smith <psmith@gnu.org> 617 618 * signame.c: HAVE_DECL_* macros are set to 0, not undef, if the 619 declaration was checked but not present. 620 6212005-06-27 Paul D. Smith <psmith@gnu.org> 622 623 * dir.c (find_directory): Change type of fs_serno/fs_flags/fs_len 624 to unsigned long. Fixes Savannah bug #13550. 625 626 * w32/subproc/sub_proc.c: Remove (HANDLE) casts on lvalues. 627 (process_pipe_io): Initialize tStdin/tStdout/tStderr variables. 628 Fixes Savannah bug #13551. 629 6302005-06-26 Paul D. Smith <psmith@gnu.org> 631 632 * make.h: Fix bug in ANSI_STRING/strerror() handling; only define 633 it if ANSI_STRING is not set. 634 6352005-06-25 Paul D. Smith <psmith@gnu.org> 636 637 * read.c (eval): If no filenames are passed to any of the 638 "include" variants, don't print an error. 639 * doc/make.texi (Include): Document this. 640 Fixes Savannah bug #1761. 641 642 * job.c (construct_command_argv_internal): Sanitize handling of 643 backslash/newline pairs according to POSIX: that is, keep the 644 backslash-newline in the command script, but remove a following 645 TAB character, if present. In the fast path, make sure that the 646 behavior matches what the shell would do both inside and outside 647 of quotes. In the slow path, quote the backslash and put a 648 literal newline in the string. 649 Fixes Savannah bug #1332. 650 * doc/make.texi (Execution): Document the new behavior and give 651 some examples. 652 * NEWS: Make a note of the new behavior. 653 654 * make.h [WINDOWS32]: #include <direct.h>. 655 Fixes Savannah bug #13478. 656 657 * remake.c (name_mtime): If the stat() of a file fails and the -L 658 option was given and the file is a symlink, take the best mtime of 659 the symlink we can get as the mtime of the file and don't fail. 660 Fixes Savannah bug #13280. 661 662 * read.c (find_char_unquote): Accept a new argument IGNOREVARS. 663 If it's set, then don't stop on STOPCHARs or BLANKs if they're 664 inside a variable reference. Make this function static as it's 665 only used here. 666 (eval): Call find_char_unquote() with IGNOREVARS set when we're 667 parsing an unexpanded line looking for semicolons. 668 Fixes Savannah bug #1454. 669 * misc.c (remove_comments): Move this to read.c and make it static 670 as it's only used there. Call find_char_unquote() with new arg. 671 * make.h: Remove prototypes for find_char_unquote() and 672 remove_comments() since they're static now. 673 674 * main.c (main): If we see MAKE_RESTARTS in the environment, unset 675 its export flag and obtain its value. When we need to re-exec, 676 increment the value and add it into the environment. 677 * doc/make.texi (Special Variables): Document MAKE_RESTARTS. 678 * NEWS: Mention MAKE_RESTARTS. 679 * main.c (always_make_set): New variable. Change the -B option to 680 set this one instead. 681 (main): When checking makefiles, only set always_make_flag if 682 always_make_set is set AND the restarts flag is 0. When building 683 normal targets, set it IFF always_make_set is set. 684 (main): Avoid infinite recursion with -W, too: only set what-if 685 files to NEW before we check makefiles if we've never restarted 686 before. If we have restarted, set what-if files to NEW _after_ we 687 check makefiles. 688 Fixes Savannah bug #7566: 689 6902005-06-17 Paul D. Smith <psmith@gnu.org> 691 692 * default.c: Change VMS implicit rules to use $$$$ instead of $$ 693 in the prerequisites list. 694 6952005-06-12 Paul D. Smith <psmith@gnu.org> 696 697 Fix Savannah bug # 1328. 698 699 * configure.in: Check for atexit(). 700 * misc.c (close_stdout): Test stdout to see if writes to it have 701 failed. If so, be sure to exit with a non-0 error code. Based on 702 code found in gnulib. 703 * make.h: Prototype. 704 * main.c (main): Install close_stdout() with atexit(). 705 7062005-06-10 Paul D. Smith <psmith@gnu.org> 707 708 VMS build updates from Hartmut Becker <Hartmut.Becker@hp.com>: 709 710 * vmsjobs.c [VMS]: Updates to compile on VMS: add some missing 711 headers; make vmsWaitForChildren() static; extern vmsify(). 712 * job.c [VMS]: Move vmsWaitForChildren() prototype to be global. 713 Don't create child_execute_job() here (it's in vmsjobs.c). 714 * makefile.vms (job.obj) [VMS]: Add vmsjobs.c as a prerequisite. 715 7162005-06-09 Paul D. Smith <psmith@gnu.org> 717 718 * variable.c (push_new_variable_scope): File variables point 719 directly to the global_setlist variable. So, inserting a new 720 scope in front of that has no effect on those variables: they 721 don't go through current_variable_set_list. If we're pushing a 722 scope and the current scope is global, push it "the other way" so 723 that the new setlist is in the global_setlist variable, and 724 next points to a new setlist with the global variable set. 725 (pop_variable_scope): Properly undo a push with the new 726 semantics. 727 Fixes Savannah bug #11913. 728 7292005-05-31 Boris Kolpackov <boris@kolpackov.net> 730 731 * job.c (reap_children): Don't die of the command failed but 732 the dontcare flag is set. Fixes Savannah bug #13216. 733 734 * implicit.c (pattern_search): When creating a target from 735 an implicit rule match, lookup pattern target and set precious 736 flag in a newly created target. Fixes Savannah bug #13218. 737 7382005-05-13 Paul D. Smith <psmith@gnu.org> 739 740 Implement "if... else if... endif" syntax. 741 742 * read.c (eval): Push all checks for conditional words ("ifeq", 743 "else", etc.) down into the conditional_line() function. 744 (conditional_line): Rework to allow "else if..." clause. New 745 return value -2 for lines which are not conditionals. The 746 ignoring flag can now also be 2, which means "already parsed a 747 true branch". If that value is seen no other branch of this 748 conditional can be considered true. In the else parsing if there 749 is extra text after the else, invoke conditional_line() 750 recursively to see if it's another conditional. If not, it's an 751 error. If so, raise the conditional value to this level instead 752 of creating a new conditional nesting level. Special check for 753 "else" and "endif", which aren't allowed on the "else" line. 754 * doc/make.texi (Conditional Syntax): Document the new syntax. 755 7562005-05-09 Paul D. Smith <psmith@gnu.org> 757 758 * Makefile.am (EXTRA_make_SOURCES): Add vmsjobs.c 759 (MAYBE_W32): Rework how SUBDIRS are handled so that "make dist" 760 recurses to the w32 directory, even on non-Windows systems. Use 761 the method suggested in the automake manual. 762 * configure.in: Add w32/Makefile to AC_CONFIG_FILES. 763 * maintMakefile (gnulib-url): They moved the texinfo.tex files. 764 7652005-05-07 Paul D. Smith <psmith@gnu.org> 766 767 * main.c (die): If we're dying with a fatal error (not that a 768 command has failed), write back any leftover tokens before we go. 769 770 * job.c (set_child_handler_action_flags): If there are jobs 771 waiting for the load to go down, set an alarm to go off in 1 772 second. This allows us to wake up from a potentially long-lasting 773 read() and start a new job if the load has gone down. Turn it off 774 after the read. 775 (job_noop): Dummy signal handler function. 776 (new_job): Invoke it with the new semantics. 777 778 * docs/make.texi: Document secondary expansion. Various cleanups 779 and random work. 780 7812005-05-03 Paul D. Smith <psmith@gnu.org> 782 783 Rename .DEFAULT_TARGET to .DEFAULT_GOAL: in GNU make terminology 784 the targets which are to ultimately be made are called "goals"; 785 see the GNU make manual. Also, MAKECMDGOALS, etc. 786 787 * filedef.h, read.c, main.c: Change .DEFAULT_TARGET to 788 .DEFAULT_GOAL, and default_target_name to default_goal_name. 789 * doc/make.texi (Special Variables): Document .DEFAULT_GOAL. 790 7912005-05-02 Paul D. Smith <psmith@gnu.org> 792 793 * job.c, vmsjobs.c (vmsWaitForChildren, vms_redirect, 794 vms_handle_apos, vmsHandleChildTerm, reEnableAst, astHandler, 795 tryToSetupYAst, child_execute_job) [VMS]: Move VMS-specific 796 functions to vmsjobs.c. #include it into jobs.c. 797 798 Grant Taylor <gtaylor@picante.com> reports that -j# can lose 799 jobserver tokens. I found that this happens when an exported 800 recursive variable contains a $(shell ...) function reference: in 801 this situation we could "forget" to write back a token. 802 803 * job.c, job.h: Add variable jobserver_tokens: counts the tokens 804 we have. It's not reliable to depend on the number of children in 805 our linked list so keep a separate count. 806 (new_job): Check jobserver_tokens rather than children && 807 waiting_jobs. Increment jobserver_tokens when we get one. 808 (free_child): If jobserver_tokens is 0, internal error. If it's 809 >1, write a token back to the jobserver pipe (we don't write a 810 token for the "free" job). Decrement jobserver_tokens. 811 812 * main.c: Add variable master_job_slots. 813 (main): Set it to hold the number of jobs requested if we're the 814 master process, when using the jobserver. 815 (die): Sanity checks: first test jobserver_tokens to make sure 816 this process isn't holding any tokens we didn't write back. 817 Second, if master_job_slots is set count the tokens left in the 818 jobserver pipe and ensure it's the same as master_job_slots (- 1). 819 8202005-04-24 Paul D. Smith <psmith@gnu.org> 821 822 Grant Taylor <gtaylor@picante.com> reports that -j# in conjunction 823 with -l# can lose jobserver tokens, because waiting jobs are not 824 consulted properly when checking for the "free" token. 825 826 * job.c (free_child): Count waiting_jobs as having tokens. 827 * job.c (new_job): Ditto. Plus, call start_waiting_jobs() here to 828 handle jobs waiting for the load to drop. 829 8302005-04-23 Paul D. Smith <psmith@gnu.org> 831 832 * main.c (main): Be careful to not core if a variable setting in 833 the environment doesn't contain an '='. This is illegal but can 834 happen in broken setups. 835 Reported by Joerg Schilling <schilling@fokus.fraunhofer.de>. 836 8372005-04-12 Paul D. Smith <psmith@gnu.org> 838 839 The second expansion feature causes significant slowdown. Timing 840 a complex makefile (GCC 4.1) shows a slowdown from .25s to just 841 read the makefile before the feature, to 11+s to do the same 842 operations after the feature. Additionally, memory usage 843 increased drastically. To fix this I added some intelligence that 844 avoids the overhead of the second expansion unless it's required. 845 846 * dep.h: Add a new boolean field, need_2nd_expansion. 847 848 * read.c (eval): When creating the struct dep for the target, 849 check if the name contains a "$"; if so set need_2nd_expansion to 1. 850 (record_files): If there's a "%" in a static pattern rule, it gets 851 converted to "$*" so set need_2nd_expansion to 1. 852 853 * file.c (expand_deps): Rework to be more efficient. Only perform 854 initialize_file_variables(), set_file_variables(), and 855 variable_expand_for_file() if the need_2nd_expansion is set. 856 857 * implicit.c (pattern_search): Default need_2nd_expansion to 0. 858 (pattern_search): Ditto. 859 * main.c (handle_non_switch_argument): Ditto. 860 (main): Ditto. 861 * read.c (read_all_makefiles): Ditto. 862 (eval_makefile): Ditto. 863 8642005-04-07 Paul D. Smith <psmith@gnu.org> 865 866 * main.c (main) [WINDOWS32]: Export PATH to sub-shells, not Path. 867 * variable.c (sync_Path_environment): Ditto. 868 Patch by Alessandro Vesely. Fixes Savannah bug #12209. 869 870 * main.c (main): Define the .FEATURES variable. 871 * NEWS: Announce .FEATURES. 872 * doc/make.texi (Special Variables): Document .FEATURES. 873 874 * remake.c (check_dep): If a file is .PHONY, update it even if 875 it's marked intermediate. Fixes Savannah bug #12331. 876 8772005-03-15 Boris Kolpackov <boris@kolpackov.net> 878 879 * file.c (expand_deps): Factor out the second expansion and 880 prerequisite line parsing logic from snap_deps(). 881 882 * file.c (snap_deps): Use expand_deps(). Expand and parse 883 prerequisites of the .SUFFIXES special target first. Fixes 884 Savannah bug #12320. 885 8862005-03-13 Paul D. Smith <psmith@gnu.org> 887 888 * main.c (main) [MSDOS]: Export SHELL in MSDOS. Requested by Eli 889 Zaretskii. 890 8912005-03-11 Paul D. Smith <psmith@gnu.org> 892 893 * signame.c (strsignal): HAVE_DECL_SYS_SIGLIST is 0 when not 894 available, not undefined (from Earnie Boyd). 895 8962005-03-10 Boris Kolpackov <boris@kolpackov.net> 897 898 * implicit.c (pattern_search): Mark an intermediate target as 899 precious if it happened to be a prerequisite of some (other) 900 target. Fixes Savannah bug #12267. 901 9022005-03-09 Paul D. Smith <psmith@gnu.org> 903 904 * read.c (eval_makefile): Add alloca(0). 905 (eval_buffer): Ditto. 906 9072005-03-09 Boris Kolpackov <boris@kolpackov.net> 908 909 * main.c (main): Use o_file instead of o_default when defining 910 the .DEFAULT_TARGET special variable. 911 * read.c (eval): Use define_variable_global() instead of 912 define_variable() when setting new value for the .DEFAULT_TARGET 913 special variable. Fixes Savannah bug #12266. 914 9152005-03-04 Boris Kolpackov <boris@kolpackov.net> 916 917 * imlicit.c (pattern_search): Mark files for which an implicit 918 rule has been found as targets. Fixes Savannah bug #12202. 919 9202005-03-04 Paul D. Smith <psmith@gnu.org> 921 922 * AUTHORS: Update. 923 * doc/make.texi (Automatic Variables): Document $|. 924 9252005-03-03 Boris Kolpackov <boris@kolpackov.net> 926 927 * read.c (record_files): Instead of substituting % with 928 actual stem value in dependency list replace it with $*. 929 This fixes stem triple expansion bug. 930 931 * implicit.c (pattern_search): Copy stem to a separate 932 buffer and make it a properly terminated string. Assign 933 this buffer instead of STEM (which is not terminated) to 934 f->stem. Instead of substituting % with actual stem value 935 in dependency list replace it with $*. This fixes stem 936 triple expansion bug. 937 9382005-03-01 Paul D. Smith <psmith@gnu.org> 939 940 * commands.c (fatal_error_signal) [WINDOWS32]: Don't call kill() 941 on Windows, as it takes a handle not a pid. Just exit. 942 Fix from patch #3679, provided by Alessandro Vesely. 943 944 * configure.in: Update check for sys_siglist[] from autoconf manual. 945 * signame.c (strsignal): Update to use the new autoconf macro. 946 9472005-03-01 Boris Kolpackov <boris@kolpackov.net> 948 949 * read.c (record_files): Add a check for the list of prerequisites 950 of a static pattern rule being empty. Fixes Savannah bug #12180. 951 9522005-02-28 Paul D. Smith <psmith@gnu.org> 953 954 * doc/make.texi (Text Functions): Update docs to allow the end 955 ordinal for $(wordlist ...) to be 0. 956 * function.c (func_wordlist): Fail if the start ordinal for 957 $(wordlist ...) is <1. Matches documentation. 958 Resolves Savannah support request #103195. 959 960 * remake.c (update_goal_chain): Fix logic for stopping in -q: 961 previously we were stopping when !-q, exactly the opposite. This 962 has been wrong since version 1.34, in 1994! 963 (update_file): If we got an error don't break out to run more 964 double-colon rules: just return immediately. 965 Fixes Savannah bug #7144. 966 9672005-02-27 Paul D. Smith <psmith@gnu.org> 968 969 * misc.c (end_of_token): Make argument const. 970 * make.h: Update prototype. 971 972 * function.c (abspath, func_realpath, func_abspath): Use 973 PATH_VAR() and GET_PATH_MAX instead of PATH_MAX. 974 * dir.c (downcase): Use PATH_VAR() instead of PATH_MAX. 975 * read.c (record_files): Ditto. 976 * variable.c (do_variable_definition): Ditto. 977 978 * function.c (func_error): Create a new function $(info ...) that 979 simply prints the message to stdout with no extras. 980 (function_table_init): Add new function to the table. 981 * NEWS: Add $(info ...) reference. 982 * doc/make.texi (Make Control Functions): Document it. 983 984 New feature: if the system supports symbolic links, and the user 985 provides the -L/--check-symlink-time flag, then use the latest 986 mtime between the symlink(s) and the target file. 987 988 * configure.in (MAKE_SYMLINKS): Check for lstat() and 989 readlink(). If both are available, define MAKE_SYMLINKS. 990 * main.c: New variable: check_symlink_flag. 991 (usage): Add a line for -L/--check-symlink-times to the help string. 992 (switches): Add -L/--check-symlink-times command line argument. 993 (main): If MAKE_SYMLINKS is not defined but the user specified -L, 994 print a warning and disable it again. 995 * make.h: Declare check_symlink_flag. 996 * remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag, 997 if the file is a symlink then check each link in the chain and 998 choose the NEWEST mtime we find as the mtime for the file. The 999 newest mtime might be the file itself! 1000 * NEWS: Add information about this new feature. 1001 * doc/make.texi (Options Summary): Add -L/--check-symlink-times docs. 1002 1003 Avoid core dumps described in Savannah bug # 12124: 1004 1005 * file.c: New variable snapped_deps remember whether we've run 1006 snap_deps(). 1007 (snap_deps): Set it. 1008 * filedef.h: Extern it. 1009 * read.c (record_files): Check snapped_deps; if it's set then 1010 we're trying to eval a new target/prerequisite relationship from 1011 within a command script, which we don't support. Fatal. 1012 10132005-02-28 Boris Kolpackov <boris@kolpackov.net> 1014 1015 Implementation of the .DEFAULT_TARGET special variable. 1016 1017 * read.c (eval): If necessary, update default_target_name when 1018 reading rules. 1019 * read.c (record_files): Update default_target_file if 1020 default_target_name has changed. 1021 * main.c (default_target_name): Define. 1022 * main.c (main): Enter .DEFAULT_TARGET as make variable. If 1023 default_target_name is set use default_target_file as a root 1024 target to make. 1025 * filedef.h (default_target_name): Declare. 1026 * dep.h (free_dep_chain): 1027 * misc.c (free_dep_chain): Change to operate on struct nameseq 1028 and change name to free_ns_chain. 1029 * file.c (snap_deps): Update to use free_ns_chain. 1030 10312005-02-27 Boris Kolpackov <boris@kolpackov.net> 1032 1033 Implementation of the second expansion in explicit rules, 1034 static pattern rules and implicit rules. 1035 1036 * read.c (eval): Refrain from chopping up rule's dependencies. 1037 Store them in a struct dep as a single dependency line. Remove 1038 the code that implements SySV-style automatic variables. 1039 1040 * read.c (record_files): Adjust the code that handles static 1041 pattern rules to expand all percents instead of only the first 1042 one. Reverse the order in which dependencies are stored so that 1043 when the second expansion reverses them again they appear in 1044 the makefile order (with some exceptions, see comments in 1045 the code). Remove the code that implements SySV-style automatic 1046 variables. 1047 1048 * file.c (snap_deps): Implement the second expansion and chopping 1049 of dependency lines for explicit rules. 1050 1051 * implicit.c (struct idep): Define an auxiliary data type to hold 1052 implicit rule's dependencies after stem substitution and 1053 expansion. 1054 1055 * implicit.c (free_idep_chain): Implement. 1056 1057 * implicit.c (get_next_word): Implement helper function for 1058 parsing implicit rule's dependency lines into words taking 1059 into account variable expansion requests. Used in the stem 1060 splitting code. 1061 1062 * implicit.c (pattern_search): Implement the second expansion 1063 for implicit rules. Also fixes bug #12091. 1064 1065 * commands.h (set_file_variables): Declare. 1066 * commands.c (set_file_variables): Remove static specifier. 1067 1068 * dep.h (free_dep_chain): Declare. 1069 * misc.c (free_dep_chain): Implement. 1070 1071 * variable.h (variable_expand_for_file): Declare. 1072 * expand.c (variable_expand_for_file): Remove static specifier. 1073 1074 * make.h (strip_whitespace): Declare. 1075 * function.c (strip_whitespace): Remove static specifier. 1076 10772005-02-26 Paul D. Smith <psmith@gnu.org> 1078 1079 * main.c (main): Check for ferror() when reading makefiles from stdin. 1080 Apparently some shells in Windows don't close pipes properly and 1081 require this check. 1082 10832005-02-24 Jonathan Grant <jg@jguk.org> 1084 1085 * configure.in: Add MinGW configuration options, and extra w32 code 1086 directory. 1087 * Makefile.am: Add MinGW configuration options, and extra w32 code 1088 directory. 1089 * main.c: Determine correct program string (after last \ without .exe). 1090 * subproc/sub_proc.c: `GetExitCodeProcess' from incompatible pointer 1091 type fix x2 1092 * w32/Makefile.am: Import to build win32 lib of sub_proc etc. 1093 * subproc/w32err.c: MSVC thread directive not applied to MinGW builds. 1094 * tests/run_make_tests.pl, tests/test_driver.pl: MSYS testing 1095 environment support. 1096 10972004-04-16 Dmitry V. Levin <ldv@altlinux.org> 1098 1099 * function.c (func_shell): When initializing error_prefix, check 1100 that reading file name is not null. This fixes long-standing 1101 segfault in cases like "make 'a1=$(shell :)' 'a2:=$(a1)'". 1102 11032005-02-09 Paul D. Smith <psmith@gnu.org> 1104 1105 * maintMakefile: Update the CVS download URL to simplify them. 1106 Also, the ftp://ftp.gnu.org/GNUinfo site was removed so I'm 1107 downloading the .texi files from Savannah now. 1108 1109 Fixed these issues reported by Markus Mauhart <qwe123@chello.at>: 1110 1111 * main.c (handle_non_switch_argument): Only add variables to 1112 command_variables if they're not already there: duplicate settings 1113 waste space and can be confusing to read. 1114 1115 * w32/include/sub_proc.h: Remove WINDOWS32. It's not needed since 1116 this header is never included by non-WINDOWS32 code, and it 1117 requires <config.h> to define which isn't always included first. 1118 1119 * dir.c (read_dirstream) [MINGW]: Use proper macro names when 1120 testing MINGW32 versions. 1121 1122 * main.c (log_working_directory): flush stdout to be sure the WD 1123 change is printed before any stderr messages show up. 1124 11252005-02-01 Paul D. Smith <psmith@gnu.org> 1126 1127 * maintMakefile (po_repo): Update the GNU translation site URL. 1128 11292004-12-01 Paul D. Smith <psmith@gnu.org> 1130 1131 * main.c (main): Change char* env_shell to struct variable shell_var. 1132 * variable.c (target_environment): Use new shell_var. 1133 11342004-11-30 Paul D. Smith <psmith@gnu.org> 1135 1136 * configure.in: The old way we avoided creating build.sh from 1137 build.sh.in before build.sh.in exists doesn't work anymore; we 1138 have to use raw M4 (thanks to Andreas Schwab <schwab@suse.de> for 1139 the help!). This also keeps automake from complaining. 1140 * Makefile.am (README): Add a dummy target so automake won't 1141 complain that this file doesn't exist when we checkout from CVS. 1142 * maintMakefile (.dep_segment): Rewrite this rule since newer 1143 versions of automake don't provide DEP_FILES. 1144 11452004-11-30 Boris Kolpackov <boris@kolpackov.net> 1146 1147 Implementation of `realpath' and `abspath' built-in functions. 1148 1149 * configure.in: Check for realpath. 1150 * function.c (abspath): Return an absolute file name that does 1151 not contain any `.' or `..' components, nor repeated `/'. 1152 * function.c (func_abspath): For each name call abspath. 1153 * function.c (func_realpath): For each name call realpath 1154 from libc or delegate to abspath if realpath is not available. 1155 * doc/make.texi (Functions for File Names): Document new functions. 1156 * doc/make.texi (Quick Reference): Ditto. 1157 11582004-11-28 Paul D. Smith <psmith@gnu.org> 1159 1160 * main.c (main) [WINDOWS32]: Remove any trailing slashes from -C 1161 arguments. Fixes bug #10252. 1162 1163 Fix for bug #1276: Handle SHELL according to POSIX requirements. 1164 1165 * main.c (main): Set SHELL to v_noexport by default. Remember the 1166 original environment setting of SHELL in the env_shell variable. 1167 * main.h: Export new env_shell variable. 1168 * variable.c (target_environment): If we find a v_noexport 1169 variable for SHELL, add a SHELL variable with the env_shell value. 1170 * doc/make.texi (Quick Reference): Document the POSIX behavior. 1171 * doc/make.texi (Variables/Recursion): Ditto. 1172 11732004-11-28 Paul D. Smith <psmith@gnu.org> 1174 1175 * main.c (find_and_set_default_shell) [WINDOWS32]: check for 1176 equality of "cmd"/"cmd.exe", not inequality. Fixes bug #11155. 1177 Patch by Alessandro Vesely. 1178 11792004-11-12 Paul D. Smith <psmith@gnu.org> 1180 1181 * job.c (child_execute_job) [VMS]: Don't treat "#" as a comment on 1182 the command line if it's inside a string. 1183 Patch by: Hartmut Becker <Hartmut.Becker@hp.com> 1184 11852004-10-21 Boris Kolpackov <boris@kolpackov.net> 1186 1187 * function.c (func_lastword): New function: return last word 1188 from the list of words. 1189 * doc/make.texi: Document $(lastword ). Fix broken links in 1190 Quick Reference section. 1191 11922004-10-06 Paul D. Smith <psmith@gnu.org> 1193 1194 Apply patch from Alessandro Vesely, provided with bug # 9748. 1195 Fix use of tmpnam() to work with Borland C. 1196 1197 * job.c (construct_command_argv_internal) [WINDOWS32]: Remove 1198 construction of a temporary filename, and call new function 1199 create_batch_filename(). 1200 (create_batch_filename) [WINDOWS32]: New function to create a 1201 temporary filename. 1202 12032004-10-05 Boris Kolpackov <boris@kolpackov.net> 1204 1205 * read.c (record_target_var): Expand simple pattern-specific 1206 variable. 1207 * variable.c (initialize_file_variables): Do not expand simple 1208 pattern-specific variable. 1209 12102004-09-28 Boris Kolpackov <boris@kolpackov.net> 1211 1212 * remake.c (update_file_1): When rebuilding makefiles inherit 1213 dontcare flag from a target that triggered update. 1214 12152004-09-27 Boris Kolpackov <boris@kolpackov.net> 1216 1217 * variable.c (initialize_file_variables): Mark pattern-specific 1218 variable as a per-target and copy export status. 1219 12202004-09-21 Boris Kolpackov <boris@kolpackov.net> 1221 1222 * file.c (snap_deps): Mark .PHONY prerequisites as targets. 1223 1224 * implicit.c (pattern_search): When considering an implicit rule's 1225 prerequisite check that it is actually a target rather then 1226 just an entry in the file hashtable. 1227 12282004-09-21 Paul D. Smith <psmith@gnu.org> 1229 1230 * read.c (readstring): Fix some logic errors in backslash handling. 1231 (eval): Remove some unnecessary processing in buffer handling. 1232 (record_target_var): Assert that parse_variable_definition() succeeded. 1233 Reported by: Markus Mauhart <qwe123@chello.at>. 1234 1235 * misc.c: Removed the sindex() function. All instances of this 1236 function were trivially replaceable by the standard strstr() 1237 function, and that function will always have better (or certainly 1238 no worse) performance than the very simple-minded algorithm 1239 sindex() used. This can matter with complex makefiles. 1240 * make.h: Remove the prototype for sindex(). 1241 * function.c (subst_expand): Convert sindex() call to strstr(). 1242 This means we no longer need to track the TLEN value so remove that. 1243 (func_findstring): Convert sindex() to strstr(). 1244 * commands.c (chop_commands): Convert sindex() calls to strstr(). 1245 Suggested by: Markus Mauhart <qwe123@chello.at>. 1246 1247 * main.c (find_and_set_default_shell) [WINDOWS32]: Implement the 1248 idea behind Savannah Patch #3144 from david.baird@homemail.com. 1249 If SHELL is set to CMD.EXE then assume it's batch-mode and 1250 non-unixy. I wrote the code differently from the patch, though, 1251 to make it safer. This also resolves bug #9174. 1252 12532004-09-20 Paul D. Smith <psmith@gnu.org> 1254 1255 * expand.c (variable_expand_string): Modify to invoke 1256 patsubst_expand() instead of subst_expand(); the latter didn't 1257 handle suffix patterns correctly. 1258 * function.c (subst_expand): Remove the SUFFIX_ONLY parameter; it 1259 was used only from variable_expand_string() and is no longer used 1260 there. 1261 (func_subst): Ditto, on call to subst_expand(). 1262 (patsubst_expand): Require the percent pointers to point to the 1263 character after the %, not to the % itself. 1264 * read.c (record_files): New call criteria for patsubst_expand(). 1265 * variable.h: Remove SUFFIX_ONLY from subst_expand() prototype. 1266 This is to fix a bug reported by Markus Mauhart <qwe123@chello.at>. 1267 12682004-09-19 Paul D. Smith <psmith@gnu.org> 1269 1270 * function.c (subst_expand): Fix a check in by_word: look for a 1271 previous blank if we're beyond the beginning of the string, not 1272 the beginning of the word. 1273 Bugs reported by Markus Mauhart <qwe123@chello.at>. 1274 12752004-05-16 Paul D. Smith <psmith@gnu.org> 1276 1277 * remake.c (update_goal_chain): Change the argument specifying 1278 whether we're rebuilding makefiles to be a global variable, 1279 REBUILDING_MAKEFILES. 1280 (complain): Extract the code that complains about no rules to make 1281 a target into a separate function. 1282 (update_file_1): If we tried to rebuild a file during the makefile 1283 rebuild phase and it was dontcare, then no message was printed. 1284 If we then try to build the same file during the normal build, 1285 print a message this time. 1286 (remake_file): Don't complain about un-remake-able files when 1287 we're rebuilding makefiles. 1288 12892004-05-11 Paul D. Smith <psmith@gnu.org> 1290 1291 * job.c (construct_command_argv_internal): OS/2 patches from 1292 Andreas Buening <andreas.buening@nexgo.de>. 1293 12942004-05-10 Paul D. Smith <psmith@gnu.org> 1295 1296 * remake.c (update_file): Don't walk the double-colon chain unless 1297 this is a double-colon rule. Fix suggested by Boris Kolpackov 1298 <boris@kolpackov.net>. 1299 1300 * makefile.vms (CFLAGS): Remove glob/globfree (see readme.vms docs) 1301 * readme.vms: New section describing OpenVMS support and issues. 1302 * default.c (default_variables): Add support for IA64. 1303 * job.c (tryToSetupYAst) [VMS]: On VMS running make in batch mode 1304 without some privilege aborts make with the error 1305 %SYSTEM-F-NOPRIV. It happens when setting up a handler for 1306 pressing Ctrl+Y and the input device is no terminal. The change 1307 catches this error and just continues. 1308 1309 Patches by Hartmut Becker <Hartmut.Becker@hp.com> 1310 13112004-04-25 Paul D. Smith <psmith@gnu.org> 1312 1313 * commands.c (set_file_variables): Set $< properly in the face of 1314 order-only prerequisites. 1315 Patch from Boris Kolpackov <boris@kolpackov.net> 1316 13172004-04-21 Bob Byrnes <byrnes@curl.com> 1318 1319 * main.c (main): Notice failures to remake makefiles. 1320 13212004-03-28 Paul D. Smith <psmith@gnu.org> 1322 1323 Patches for Acorn RISC OS by Peter Naulls <peter@chocky.org> 1324 1325 * job.c: No default shell for RISC OS. 1326 (load_too_high): Hard-code the return to 1. 1327 (construct_command_argv_internal): No sh_chars or sh_cmds. 1328 * getloadavg.c: Don't set LOAD_AVE_TYPE on RISC OS. 1329 13302004-03-20 Paul D. Smith <psmith@gnu.org> 1331 1332 * variable.c (do_variable_definition): Don't append from the 1333 global set if a previous non-appending target-specific variable 1334 definition exists. Reported by Oliver Schmidt <oschmidt@gmx.net> 1335 (with fix). 1336 1337 * expand.c (reference_variable): Don't give up on variables with 1338 no value that have the target-specific append flag set: they might 1339 have a value after all. Reported by Oliver Schmidt 1340 <oschmidt@gmx.net> (with fix) and also by Maksim A. Nikulin 1341 <nikulin@dx1cmd.inp.nsk.su>. 1342 1343 * rule.c (count_implicit_rule_limits): Don't delete patterns which 1344 refer to absolute pathnames in directories that don't exist: some 1345 portion of the makefile could create those directories before we 1346 match the pattern. Fixes bugs #775 and #108. 1347 1348 Fixes from Jonathan R. Grant <jg-make@jguk.org>: 1349 1350 * main.c (main): Free makefile_mtimes if we have any. 1351 * README.W32.template: Update documentation for the current status 1352 of the MS-Windows port. 1353 * NMakefile.template (MAKE): Add "MAKE = nmake". A conflicting 1354 environment variable is sometimes already defined which causes the 1355 build to fail. 1356 * main.c (debug_signal_handler): Only define this function if 1357 SIGUSR1 is available. 1358 1359 Fixes for OS/2 from Andreas Beuning <andreas.buening@nexgo.de>: 1360 1361 * configure.in [OS/2]: Relocate setting of HAVE_SA_RESTART for OS/2. 1362 * README.OS2.template: Documentation updates. 1363 * build.template: Add LIBINTL into LOADLIBES. Add $CFLAGS to the 1364 link line for safety. 1365 * maintMakefile (build.sh.in): Remove an extraneous ")". 1366 * job.c (child_execute_job): Close saved FDs. 1367 * job.c (exec_command) [OS/2]: exec_command(): If the command 1368 can't be exec'ed and if the shell is not Unix-sh, then try again 1369 with argv = { "cmd", "/c", ... }. Normally, this code is never 1370 reached for the cmd shell unless the command really doesn't exist. 1371 (construct_command_argv_internal) [OS/2]: The code for cmd 1372 handling now uses new_argv = { "cmd", "/c", "original line", NULL}. 1373 The CMD builtin commands are case insensitive so use strcasecmp(). 1374 13752004-03-19 Paul D. Smith <psmith@gnu.org> 1376 1377 * read.c (do_define): Re-order line counter increment so the count 1378 is accurate (we were losing one line per define). Reported by 1379 Dave Yost <Dave@Yost.com>. 1380 13812004-03-06 Paul D. Smith <psmith@gnu.org> 1382 1383 * configure.in (HAVE_ANSI_COMPILER): Define if we have an ANSI/ISO 1384 compiler. 1385 * make.h: Convert uses of __STDC__ to HAVE_ANSI_COMPILER. 1386 * misc.c (message,error,fatal): Ditto. 1387 * configh.dos.template: Define HAVE_ANSI_COMPILER. 1388 * config.h.W32.template: Ditto. 1389 * config.h-vms.template: Ditto. 1390 * config.ami.template: Ditto. 1391 13922004-03-04 Paul D. Smith <psmith@gnu.org> 1393 1394 * README.template: Add a note about broken /bin/sh on SunOS 1395 4.1.3_U1 & 4.1.4. Fix up Savannah links. 1396 1397 * misc.c (message, error, fatal): Don't use "..." if we're using 1398 varargs. ansi2knr should handle this but it doesn't work: it 1399 translates "..." to va_dcl etc. but _AFTER_ the preprocessor is 1400 done. On many systems (SunOS for example) va_dcl is a #define. 1401 So, force the use of the non-"..." version on pre-ANSI compilers. 1402 1403 * maintMakefile (sign-dist): Create some rules to help automate 1404 the new GNU ftp upload method. 1405 14062004-02-24 Paul D. Smith <psmith@gnu.org> 1407 1408 * config.h.W32.template: Add HAVE_STDARG_H 1409 * config.h-vms.template: Ditto. 1410 * config.ami.template: Ditto. 1411 14122004-02-23 Jonathan Grant <jg-make@jguk.org> 1413 1414 * README.W32.template: Add a notation about -j with BATCH_MODE_ONLY. 1415 * build_w32.bat: Remove extra "+". 1416 14172004-02-23 Paul D. Smith <psmith@gnu.org> 1418 1419 * make.h: Create an UNUSED macro to mark unused parameters. 1420 * (many): Clean up warnings by applying UNUSED, fixing 1421 signed/unsigned incompatibilities, etc. 1422 1423 * acinclude.m4 (AC_STRUCT_ST_MTIM_NSEC): Add quoting to silence 1424 autoconf warnings. 1425 * filedef.h: Name the command_state enumeration. 1426 * file.c (set_command_state): Use the enumeration in the function 1427 argument. 1428 1429 * configure.in: Explicitly set SET_MAKE to empty, to disable 1430 MAKE=make even when no make already exists. Fix bug #3823. 1431 14322004-02-22 Paul D. Smith <psmith@gnu.org> 1433 1434 * maintMakefile: Perl script to clean up all non-CVS files. Use 1435 it on all the subdirectories for the cvs-clean target. 1436 1437 * main.c (decode_switches): Require non-empty strings for all our 1438 string command-line options. Fixes Debian bug # 164165. 1439 1440 * configure.in: Check for stdarg.h and varargs.h. 1441 * make.h (USE_VARIADIC): Set this if we can use variadic functions 1442 for printing messages. 1443 * misc.c: Check USE_VARIADIC instead of (obsolete) HAVE_STDVARARGS. 1444 (message): Ditto. 1445 (error): Ditto. 1446 (fatal): Ditto. 1447 1448 A number of patches for OS/2 support from Andreas Buening 1449 <andreas.buening@nexgo.de>: 1450 1451 * job.c (child_handler) [OS/2]: Allow this on OS/2 but we have to 1452 disable the SIGCHLD handler. 1453 (reap_children) [OS/2]: Remove special handling of job_rfd. 1454 (set_child_handler_action_flags) [OS/2]: Use this function in OS/2. 1455 (new_job) [OS/2]: Disable the SIGCHLD handler on OS/2. 1456 * main.c (main) [OS/2]: Special handling for paths in OS/2. 1457 * configure.in [OS/2]: Force SA_RESTART for OS/2. 1458 * Makefile.am (check-regression): Use $(EXEEXT) for Windows-type 1459 systems. 1460 14612004-02-21 Paul D. Smith <psmith@gnu.org> 1462 1463 * w32/subproc/sub_proc.c (process_easy) [W32]: Christoph Schulz 1464 <mail@kristov.de> reports that if process_begin() fails we don't 1465 handle the error condition correctly in all cases. 1466 * w32/subproc/w32err.c (map_windows32_error_to_string): Make sure 1467 to have a newline on the message. 1468 1469 * job.c (construct_command_argv_internal): Add "test" to UNIX 1470 sh_cmds[]. Fixes Savannah bug # 7606. 1471 14722004-02-04 Paul D. Smith <psmith@gnu.org> 1473 1474 * job.c (vms_handle_apos) [VMS]: Fix various string handling 1475 situations in VMS DCL. Fixes Savannah bug #5533. Fix provided by 1476 Hartmut Becker <Hartmut.Becker@hp.com>. 1477 14782004-01-21 Paul D. Smith <psmith@gnu.org> 1479 1480 * job.c (load_too_high): Implement an algorithm to control the 1481 "thundering herd" problem when using -l to control job creation 1482 via the load average. The system only recomputes the load once a 1483 second but we can start many jobs in a second. To solve this we 1484 keep track of the number of jobs started in the last second and 1485 apply a weight to try to guess what a correct load would be. 1486 The algorithm was provided by Thomas Riedl <thomas.riedl@siemens.com>. 1487 Also fixes bug #4693. 1488 (reap_children): Decrease the job count for this second. 1489 (start_job_command): Increase the job count for this second. 1490 1491 * read.c (conditional_line): Expand the text after ifn?def before 1492 checking to see if it's a single word. Fixes bug #7257. 1493 14942004-01-09 Paul D. Smith <psmith@gnu.org> 1495 1496 * file.c (print_file): Recurse to print all targets in 1497 double-colon rules. Fixes bug #4518, reported (with patch) by 1498 Andrew Chatham <chatham@google.com>. 1499 15002004-01-07 Paul D. Smith <psmith@gnu.org> 1501 1502 * acinclude.m4: Remove make_FUNC_SETVBUF_REVERSED. 1503 * configure.in: Change make_FUNC_SETVBUF_REVERSED to 1504 AC_FUNC_SETVBUF_REVERSED. 1505 1506 * doc/make.texi (Target-specific): Fix Savannah bug #1772. 1507 (MAKE Variable): Fix Savannah bug #4898. 1508 1509 * job.c (construct_command_argv_internal): Add "!" to the list of 1510 shell escape chars. POSIX sh allows it to appear before a 1511 command, to negate the exit code. Fixes bug #6404. 1512 1513 * implicit.c (pattern_search): When matching an implicit rule, 1514 remember which dependencies have the ignore_mtime flag set. 1515 Original fix provided in Savannah patch #2349, by Benoit 1516 Poulot-Cazajous <Benoit.Poulot-Cazajous@jaluna.com>. 1517 15182003-11-22 Paul D. Smith <psmith@gnu.org> 1519 1520 * README.W32.template (Outputs): Clarification on -j with 1521 BATCH_MODE_ONLY_SEHLL suggested by Jonathan R. Grant 1522 <jg-make@jguk.org>. 1523 15242003-11-02 Paul D. Smith <psmith@gnu.org> 1525 1526 * function.c (func_if): Strip all the trailing whitespace from the 1527 condition, then don't expand it. Fixed bug # 5798. 1528 1529 * expand.c (recursively_expand_for_file): If we're expanding a 1530 variable with no file context, then use the variable's context. 1531 Fixes bug # 6195. 1532 15332003-10-21 Paul D. Smith <psmith@gnu.org> 1534 1535 * main.c (log_working_directory): Add newlines to printf()s. 1536 1537 * README.cvs: Add a note to ignore warnings during autoreconf. 1538 1539 * maintMakefile (po_repo): Set a new URL for PO file updates. 1540 (get-config/config.guess get-config/config.sub): Get these files 1541 from the Savannah config project instead of ftp.gnu.org. 1542 15432003-10-05 Paul Eggert <eggert@twinsun.com> 1544 1545 * main.c (main): Avoid potential subscript error if environ has 1546 short strings. 1547 15482003-08-22 Paul D. Smith <psmith@gnu.org> 1549 1550 * misc.c (xmalloc, xrealloc): Add one to 0 sizes, to cater to 1551 systems which don't yet implement the C89 standard :-/. 1552 15532003-07-18 Paul D. Smith <psmith@gnu.org> 1554 1555 * dir.c (directory_contents_hash_1, directory_contents_hash_1) 1556 [WINDOWS32]: Initialize hash. 1557 15582003-06-19 Earnie Boyd <earnie@uses.sf.net> 1559 1560 * dir.c (read_dirstream): Provide a workaround for broken versions of 1561 the MinGW dirent structure. 1562 15632003-05-30 Earnie Boyd <earnie@users.sf.net> 1564 1565 * w32/include/dirent.h: Add __MINGW32__ filter. 1566 15672003-05-30 Earnie Boyd <earnie@users.sf.net> 1568 1569 * make.h: Add global declaration of *make_host. 1570 * main.c (print_usage): Remove local declaration of *make_host. 1571 (print_version): Display "This program built for ..." after Copyright 1572 notice. 1573 15742003-05-30 Earnie Boyd <earnie@users.sf.net> 1575 1576 * doc/make.texi: Change "ifinfo" to "ifnottex" as suggested by the 1577 execution of "makeinfo --html make.texi". 1578 15792003-04-30 Paul D. Smith <psmith@gnu.org> 1580 1581 * build.template: Make some changes to maybe allow this script to 1582 work on DOS/Windows/OS2 systems. Suggested by Andreas Buening. 1583 1584 * README.OS2.template: New file for OS/2 support. Original 1585 contributed by Andreas Buening. 1586 * configure.in: Invoke new pds_AC_DOS_PATHS macro to test for 1587 DOS-style paths. 1588 15892003-04-19 Paul D. Smith <psmith@gnu.org> 1590 1591 Fix bug #1405: allow a target to match multiple pattern-specific 1592 variables. 1593 1594 * rule.c (create_pattern_var, lookup_pattern_var): Move these to 1595 variable.c, where they've always belonged. 1596 * rule.h: Move the prototypes and struct pattern_var as well. 1597 * variable.c (initialize_file_variables): Invoke 1598 lookup_pattern_var() in a loop, until no more matches are found. 1599 If a match is found, create a new variable set for the target's 1600 pattern variables. Then merge the contents of each matching 1601 pattern variable set into the target's pattern variable set. 1602 (lookup_pattern_var): Change this function to be usable 1603 in a loop. It takes a starting position: if NULL, start at the 1604 beginning; if non-NULL, start with the pattern variable after that 1605 position, and return the next matching pattern. 1606 (create_pattern_var): Create a unique instance of 1607 pattern-specific variables for every definition in the makefile. 1608 Don't combine the same pattern together. This allows us to 1609 process the variable handling properly even when the same pattern 1610 is used multiple times. 1611 (parse_variable_definition): New function: break out the parsing 1612 of a variable definition line from try_variable_definition. 1613 (try_variable_definition): Call parse_variable_definition to 1614 parse. 1615 (print_variable_data_base): Print out pattern-specific variables. 1616 * variable.h (struct variable): Remember when a variable is 1617 conditional. Also remember its flavor. 1618 (struct pattern_var): Instead of keeping a variable set, we just 1619 keep a single variable for each pattern. 1620 * read.c (record_target_var): Each pattern variable contains only a 1621 single variable, not a set, so create it properly. 1622 * doc/make.texi (Pattern-specific): Document the new behavior. 1623 16242003-04-17 Paul D. Smith <psmith@gnu.org> 1625 1626 * dir.c (file_exists_p) [VMS]: Patch provided with Bug #3018 by 1627 Jean-Pierre Portier <portierjp2@free.fr>. I don't understand the 1628 file/directory naming rules for VMS so I can't tell whether this 1629 is correct or not. 1630 16312003-04-09 Paul D. Smith <psmith@gnu.org> 1632 1633 * configure.in (HAVE_DOS_PATHS): Define this on systems that need 1634 DOS-style pathnames: backslash separators and drive specifiers. 1635 16362003-03-28 Paul D. Smith <psmith@gnu.org> 1637 1638 * file.c (snap_deps): If .SECONDARY with no targets is given, set 1639 the intermediate flag on all targets. Fixes bug #2515. 1640 16412003-03-24 Paul D. Smith <psmith@gnu.org> 1642 1643 * configure.in, Makefile.am, glob/Makefile.am, doc/Makefile.am: 1644 Upgrade to autoconf 2.57 and automake 1.7.3. 1645 1646 * job.c: More OS/2 changes from Andreas Buening. 1647 1648 * file.c (print_file): Fix variable initialization. 1649 Fixes bug #2892. 1650 1651 * remake.c (notice_finished_file): 1652 1653 * make.h (ENULLLOOP): Set errno = 0 before invoking the command; 1654 some calls (like readdir()) return NULL in valid situations 1655 without resetting errno. Fixes bug #2846. 1656 16572003-02-25 Paul D. Smith <psmith@gnu.org> 1658 1659 Port to OS/2 (__EMX__) by Andreas Buening <andreas.buening@nexgo.de>. 1660 1661 * job.c (_is_unixy_shell) [OS/2]: New function. 1662 Set default shell to /bin/sh. 1663 (reap_children): Close the job_rfd pipe here since we don't use a 1664 SIGCHLD handler. 1665 (set_child_handler_action_flags): define this to empty on OS/2. 1666 (start_job_command): Close the jobserver pipe and use 1667 child_execute_job() instead of fork/exec. 1668 (child_execute_job): Rewrite to handle stdin/stdout FDs and spawn 1669 rather than exec'ing, then reconfigure stdin/stdout. 1670 (exec_command): Rewrite to use spawn instead of exec. Return the 1671 PID of the child. 1672 1673 * main.c (main) [OS/2]: Call initialize_main(). Handle argv[0] as 1674 in DOS. Handle the TEMP environment variable as in DOS. Don't 1675 use a SIGCHLD handler on OS/2. Choose a shell as in DOS. Don't 1676 use -j in DOS mode. Use child_execute_job() instead of 1677 exec_command(). 1678 1679 * function.c (func_shell) [OS/2]: Can't use fork/exec on OS/2: use 1680 spawn() instead. 1681 1682 * job.h [OS/2]: Move CLOSE_ON_EXEC here from job.c. Add 1683 prototypes that return values. 1684 1685 * remake.c (f_mtime) [OS/2]: Handle FAT timestamp offsets for OS/2. 1686 1687 * read.c (readline) [OS/2]: Don't handle CRLF specially on OS/2. 1688 * default.c (default_suffixes) [OS/2]: Set proper default suffixes 1689 for OS/2. 1690 * vpath.c (construct_vpath_list) [OS/2]: Handle OS/2 paths like 1691 DOS paths. 1692 16932003-02-24 Paul D. Smith <psmith@gnu.org> 1694 1695 * default.c [VMS]: New default rules for .cxx -> .obj compiles. 1696 * job.c (child_execute_job) [VMS]: New code for handling spawn(). 1697 (child_execute_job) [VMS]: Handle error status properly. 1698 Patches provided by Hartmut Becker <Hartmut.Becker@compaq.com>. 1699 1700 * function.c (func_shell): Use EINTRLOOP() while reading from the 1701 subshell pipe (Fixes bug #2502). 1702 * job.c (free_child): Use EINTRLOOP() while writing tokens to the 1703 jobserver pipe. 1704 * main.c (main): Ditto. 1705 17062003-01-30 Paul D. Smith <psmith@gnu.org> 1707 1708 * read.c (eval): eval() was not fully reentrant, because the 1709 collapsed buffer was static. Change it to be an automatic 1710 variable so that eval() can be invoked recursively. 1711 Fixes bug # 2238. 1712 (eval): Apply patch # 1022: fix memory reference error on long 1713 target-specific variable lines. 1714 Patch provided by Steve Brown <Steve.Brown@macquarie.com>. 1715 1716 * function.c (check_numeric): Combine the is_numeric() function 1717 into this function, since it's only called from one place. 1718 Constify this function. Have it print the incorrect string in the 1719 error message. Fixes bug #2407. 1720 (strip_whitespace): Constify. 1721 (func_if): Constify. 1722 * expand.c (expand_argument): Constify. 1723 17242003-01-29 Paul D. Smith <psmith@gnu.org> 1725 1726 Fix bug # 2169, also reported by other people on various systems. 1727 1728 * make.h: Some systems, such as Solaris and PTX, do not fully 1729 implement POSIX-compliant SA_RESTART functionality; important 1730 system calls like stat() and readdir() can still fail with EINTR 1731 even if SA_RESTART has been set on the signal handler. So, 1732 introduce macros EINTRLOOP() and ENULLLOOP() which can loop on 1733 EINTR for system calls which return -1 or 0 (NULL), respectively, 1734 on error. 1735 Also, remove the old atomic_stat()/atomic_readdir() and 1736 HAVE_BROKEN_RESTART handling. 1737 1738 * configure.in: Remove setting of HAVE_BROKEN_RESTART. 1739 1740 * arscan.c (ar_member_touch): Use EINTRLOOP() to wrap fstat(). 1741 * remake.c (touch_file): Ditto. 1742 1743 * commands.c (delete_target): Use EINTRLOOP() to wrap stat(). 1744 * read.c (construct_include_path): Ditto. 1745 * remake.c (name_mtime): Ditto. 1746 * vpath.c (selective_vpath_search): Ditto. 1747 * dir.c (find_directory): Ditto. 1748 (local_stat): Ditto. 1749 (find_directory): Use ENULLLOOP() to wrap opendir(). 1750 (dir_contents_file_exists_p): Use ENULLLOOP() to wrap readdir(). 1751 1752 * misc.c: Remove HAVE_BROKEN_RESTART, atomic_stat(), and 1753 atomic_readdir() handling. 1754 17552003-01-22 Paul D. Smith <psmith@gnu.org> 1756 1757 * function.c (func_call): Fix Bug #1744. If we're inside a 1758 recursive invocation of $(call ...), mask any of the outer 1759 invocation's arguments that aren't used by this one, so that this 1760 invocation doesn't "inherit" them accidentally. 1761 17622002-12-05 Paul D. Smith <psmith@gnu.org> 1763 1764 * function.c (subst_expand): Valery Khamenia reported a 1765 pathological performance hit when doing substitutions on very 1766 large values with lots of words: turns out we were invoking 1767 strlen() a ridiculous number of times. Instead of having each 1768 call to sindex() call strlen() again, keep track of how much of 1769 the text we've seen and pass the length to sindex(). 1770 17712002-11-19 Paul D. Smith <psmith@gnu.org> 1772 1773 * README.cvs, configure.in: Upgrade to require autoconf 2.56. 1774 1775 17762002-11-16 Paul D. Smith <psmith@gnu.org> 1777 1778 * NMakefile.template (OBJS): Add hash.c object file. 1779 * SMakefile.template (srcs): Ditto. 1780 * Makefile.ami (objs): Ditto. 1781 * build_w32.bat: Ditto. 1782 1783 * Makefile.DOS.template: Remove extra dependencies. 1784 17852002-10-25 Paul D. Smith <psmith@gnu.org> 1786 1787 * expand.c (install_variable_buffer): New function. Install a new 1788 variable_buffer context and return the previous one. 1789 (restore_variable_buffer): New function. Free the current 1790 variable_buffer context and put a previously saved one back. 1791 * variable.h: Prototypes for {install,restore}_variable_buffer. 1792 * function.c (func_eval): Push a new variable_buffer context 1793 before we eval, then restore the old one when we're done. 1794 Fixes Bug #1517. 1795 1796 * read.c (install_conditionals): New function. Install a new 1797 conditional context and return the previous one. 1798 (restore_conditionals): New function. Free the current 1799 conditional context and put a previously saved one back. 1800 (eval): Use the {install,restore}_conditionals for "include" 1801 handling. 1802 (eval_buffer): Use {install,restore}_conditionals to preserve the 1803 present conditional state before we evaluate the buffer. 1804 Fixes Bug #1516. 1805 1806 * doc/make.texi (Quick Reference): Add references to $(eval ...) 1807 and $(value ...). 1808 (Recursion): Add a variable index entry for CURDIR. 1809 1810 * README.cvs: Update to appropriate versions. 1811 * Makefile.am (nodist_loadavg_SOURCES): automake gurus point out I 1812 don't need to copy loadavg.c: automake is smart enough to create 1813 it for me. Still have a bug in automake related to ansi2knr tho. 1814 18152002-10-14 Paul D. Smith <psmith@gnu.org> 1816 1817 * remake.c (notice_finished_file): Only touch targets if they have 1818 at least one command (as per POSIX). Resolve Bug #1418. 1819 1820 * *.c: Convert to using ANSI C-style function definitions. 1821 * Makefile.am: Enable the ansi2knr feature of automake. 1822 * configure.in: ditto. 1823 18242002-10-13 Paul D. Smith <psmith@gnu.org> 1825 1826 * commands.c (set_file_variables): Bug #1379: Don't use alloca() 1827 for automatic variable values like $^, etc. In the case of very 1828 large lists of prerequisites this causes problems. Instead reuse 1829 a static buffer (resizeable) for each variable. 1830 1831 * read.c (eval): Fix Bug #1391: allow "export" keyword in 1832 target-specific variable definitions. Check for it and set an 1833 "exported" flag. 1834 (record_target_var): Set the export field to v_export if the 1835 "exported" flag is set. 1836 * doc/make.texi (Target-specific): Document the ability to use 1837 "export". 1838 1839 * doc/make.texi: Change the name of the section on automatic 1840 variables from "Automatic" to "Automatic Variables". Added text 1841 clarifying the scope of automatic variables. 1842 18432002-10-04 Paul D. Smith <psmith@gnu.org> 1844 1845 * read.c (eval): Allow SysV $$@ variables to use {} braces as well 1846 as () braces. 1847 (record_files): Ditto. 1848 1849 * expand.c (variable_expand_string): In $(A:x=y) expansion limit 1850 the search for the '=' to only within the enclosing parens. 1851 18522002-10-03 Paul D. Smith <psmith@gnu.org> 1853 1854 Version 3.80 released. 1855 1856 * dir.c: Change hash functions to use K&R function definition style. 1857 * function.c: Ditto. 1858 * read.c: Ditto. 1859 * variable.c: Ditto. 1860 1861 Update to automake 1.7. 1862 1863 * Makefile.am (AUTOMAKE_OPTIONS): Update to require 1.7. 1864 (pdf): Remove this target as automake now provides one. 1865 1866 * configure.in: Change AM_CONFIG_HEADER to AC_CONFIG_HEADERS. 1867 18682002-09-30 Martin P.J. Zinser <zinser@decus.de> 1869 1870 * makefile.com: Updates for GNU make 3.80. 1871 * makefile.vms: Ditto. 1872 18732002-09-23 Paul D. Smith <psmith@gnu.org> 1874 1875 * read.c (enum make_word_type): Remove w_comment. 1876 (get_next_mword): Don't treat comment characters as special; where 1877 this function is used we will never see a comment (it's stripped 1878 before we get here) and treating comments specially means that 1879 targets like "foo\#bar" aren't handled properly. 1880 18812002-09-18 Paul D. Smith <psmith@gnu.org> 1882 1883 * doc/make.texi (Bugs): Update with some info on Savannah, etc. 1884 1885 * read.c (eval): Expansion of arguments to export/unexport was 1886 ignoring all arguments after the first one. Change the algorithm 1887 to expand the whole line once, then parse the results. 1888 18892002-09-17 Paul D. Smith <psmith@gnu.org> 1890 1891 Fix Bug #940 (plus another bug I found while looking at this): 1892 1893 * read.c (record_target_var): enter_file() will add a new entry if 1894 it's a double-colon target: we don't want to do that in this 1895 situation. Invoke lookup_file() and only enter_file() if it does 1896 not already exist. If the file we get back is a double-colon then 1897 add this variable to the "root" double-colon target. 1898 1899 * variable.c (initialize_file_variables): If this file is a 1900 double-colon target but is not the "root" target, then initialize 1901 the root and make the root's variable list the parent of our 1902 variable list. 1903 19042002-09-13 Paul D. Smith <psmith@gnu.org> 1905 1906 * doc/make.texi (MAKE Variable): Add some indexing for "+". 1907 1908 * hash.c (round_up_2): Get rid of a warning. 1909 19102002-09-12 Paul D. Smith <psmith@gnu.org> 1911 1912 * Makefile.am (loadavg_SOURCES, loadavg.c): Tiptoe around automake 1913 so it doesn't complain about getloadavg.c. 1914 1915 * commands.c (set_file_variables): Make sure we always alloca() at 1916 least 1 character for the value of $? (for '\0'). 1917 19182002-09-11 Paul D. Smith <psmith@gnu.org> 1919 1920 * hash.h (STRING_COMPARE, ISTRING_COMPARE, STRING_N_COMPARE): Fix 1921 macro to use RESULT instead of the incorrect _RESULT_. 1922 1923 * make.h (HAVE_BROKEN_RESTART): Add prototypes for atomic_stat() 1924 and atomic_readdir(). We need to #include dirent.h to get this to 1925 work. 1926 * misc.c (atomic_readdir): Fix typos. 1927 19282002-09-10 Paul D. Smith <psmith@gnu.org> 1929 1930 * read.c (eval): Expand variable lists given to export and 1931 unexport, so that "export $(LIST_OF_VARIABLES)" (etc.) works. 1932 (conditional_line): Ditto for "ifdef". Fixes bug #103. 1933 1934 * doc/make.texi (Variables/Recursion): Document this. 1935 (Conditional Syntax): And here. 1936 19372002-09-09 Paul D. Smith <psmith@gnu.org> 1938 1939 * configure.in: Check for memmove(). 1940 19412002-09-07 Paul D. Smith <psmith@gnu.org> 1942 1943 * configure.in (HAVE_BROKEN_RESTART): Define this on PTX systems; 1944 Michael Sterrett <msterret@coat.com> reports that while it has 1945 SA_RESTART, it does not work properly. 1946 1947 * misc.c (atomic_stat): If HAVE_BROKEN_RESTART, create a function 1948 that invokes stat() and loops to do it again if it returns EINTR. 1949 (atomic_readdir): Ditto, with readdir(). 1950 1951 * make.h (stat, readdir): If HAVE_BROKEN_RESTART, alias stat() 1952 and readdir() to atomic_stat() and atomic_readdir(). 1953 19542002-09-04 Paul D. Smith <psmith@gnu.org> 1955 1956 * implicit.c (pattern_search): Daniel <barkalow@reputation.com> 1957 reports that GNU make sometimes doesn't recognize that targets can 1958 be made, when directories can be created as prerequisites. He 1959 reports that changing the order of predicates in the DEP->changed 1960 flag test so that lookup_file() is always performed, solves this 1961 problem. 1962 19632002-08-08 Paul D. Smith <psmith@gnu.org> 1964 1965 * configure.in: Require a newer version of gettext. 1966 1967 * misc.c (perror_with_name): Translate the format string (for 1968 right-to-left language support). 1969 (pfatal_with_name): Ditto. 1970 1971 * main.c: Create a static array of strings to store the usage 1972 text. This is done to facilitate translations. 1973 (struct command_switch): Remove argdesc and description fields. 1974 (switches): Remove values for obsolete fields. 1975 (print_usage): Print each element of the usage array. 1976 1977 * hash.c: Change function definitions to be K&R style. 1978 19792002-08-02 Paul D. Smith <psmith@gnu.org> 1980 1981 * NEWS: Remove the mention of .TARGETS; we aren't going to publish 1982 this one because it's too hard to get right. We'll look at it for 1983 a future release. 1984 * main.c (main): Don't create the .TARGETS variable. 1985 * variable.c (handle_special_var): Don't handle .TARGETS. 1986 19872002-08-01 Paul D. Smith <psmith@gnu.org> 1988 1989 * main.c (switches): Add a new option, -B (--always-make). If 1990 specified, make will rebuild all targets that it encounters even 1991 if they don't appear to be out of date. 1992 (always_make_flag): New flag. 1993 * make.h: Extern always_make_flag. 1994 * remake.c (update_file_1): Check always_make_flag; if it's set we 1995 will always rebuild any target we can, even if none of its 1996 prerequisites are newer. 1997 * NEWS: Mention it. 1998 1999 * doc/make.texi (Shell Function): Make it clear that make 2000 variables marked as "export" are not passed to instances of the 2001 shell function. 2002 2003 Add new introspection variable .VARIABLES and .TARGETS. 2004 2005 * variable.c (handle_special_var): New function. If the variable 2006 reference passed in is "special" (.VARIABLES or .TARGETS), 2007 calculate the new value if necessary. .VARIABLES is handled here: 2008 walk through the hash of defined variables and construct a value 2009 which is a list of the names. .TARGETS is handled by 2010 build_target_list(). 2011 (lookup_variable): Invoke handle_special_var(). 2012 * file.c (build_target_list): Walk through the hask of known files 2013 and construct a list of the names of all the ones marked as 2014 targets. 2015 * main.c (main): Initialize them to empty (and as simple variables). 2016 * doc/make.texi (Special Variables): Document them. 2017 * NEWS: Mention them. 2018 2019 * variable.h (struct variable): Add a new flag "exportable" which 2020 is true if the variable name is valid for export. 2021 * variable.c (define_variable_in_set): Set "exportable" when a new 2022 variable is defined. 2023 (target_environment): Use the "exportable" flag instead of 2024 re-checking the name here... an efficiency improvement. 2025 20262002-07-31 Paul D. Smith <psmith@gnu.org> 2027 2028 * config.h-vms.template: Updates to build on VMS. Thanks to 2029 Brian_Benning@aksteel.com for helping verify the build. 2030 * makefile.com: Build the new hash.c file. 2031 * hash.h: Use strcpmi(), not stricmp(), in the 2032 HAVE_CASE_INSENSITIVE_FS case. 2033 20342002-07-30 Paul D. Smith <psmith@gnu.org> 2035 2036 * hash.h (ISTRING_COMPARE, return_ISTRING_COMPARE): Add missing 2037 backslashes to the HAVE_CASE_INSENSITIVE_FS case. 2038 Reported by <Brian_Benning@aksteel.com>. 2039 20402002-07-10 Paul D. Smith <psmith@gnu.org> 2041 2042 * variable.c (pop_variable_scope): Remove variable made unused by 2043 new hash infrastructure. 2044 * read.c (dep_hash_cmp): Rewrite this to handle ignore_mtime 2045 comparisons as well as name comparisons. 2046 * variable.h: Add a prototype for new hash_init_function_table(). 2047 * file.c (lookup_file): Remove variables made unused by new hash 2048 infrastructure. 2049 * dir.c (directory_contents_hash_2): Missing return of hash value. 2050 (dir_contents_file_exists_p): Remove variables made unused by new 2051 hash infrastructure. 2052 2053 2054 Installed Greg McGary's integration of the hash functions from the 2055 GNU id-utils package: 2056 20572002-07-10 Greg McGary <greg@mcgary.org> 2058 2059 * scripts/functions/filter-out: Add literals to to the 2060 pattern space in order to add complexity, and trigger 2061 use of an internal hash table. Fix documentation strings. 2062 * scripts/targets/INTERMEDIATE: Reverse order of files 2063 passed to expected `rm' command. 2064 20652002-07-10 Greg McGary <greg@mcgary.org> 2066 2067 * Makefile.am (SRCS): Add hash.c (noinst_HEADERS): Add hash.h 2068 * hash.c: New file, taken from id-utils. 2069 * hash.h: New file, taken from id-utils. 2070 2071 * make.h (HASH, HASHI): Remove macros. 2072 (find_char_unquote): Change arglist in decl. 2073 (hash_init_directories): New function decl. 2074 * variable.h (hash.h): New #include. 2075 (MAKELEVEL_NAME, MAKELEVEL_LENGTH): New constants. 2076 * filedef.h (hash.h): New #include. 2077 (struct file) [next]: Remove member. 2078 (file_hash_enter): Remove function decl. 2079 (init_hash_files): New function decl. 2080 2081 * ar.c (ar_name): Delay call to strlen until needed. 2082 * main.c (initialize_global_hash_tables): New function. 2083 (main): Call it. Use MAKELEVEL_NAME & MAKELEVEL_LENGTH. 2084 * misc.c (remove_comments): Pass char constants to find_char_unquote. 2085 * remake.c (notice_finished_file): Update last_mtime on `prev' chain. 2086 2087 * dir.c (hash.h): New #include. 2088 (struct directory_contents) [next, files]: Remove members. 2089 [ctime]: Add member for VMS. [dirfiles]: Add hash-table member. 2090 (directory_contents_hash_1, directory_contents_hash_2, 2091 directory_contents_hash_cmp): New functions. 2092 (directories_contents): Change type to `struct hash_table'. 2093 (struct directory) [next]: Remove member. 2094 (directory_hash_1, directory_hash_2, directory_hash_cmp): New funcs. 2095 (directory): Change type to `struct hash_table'. 2096 (struct dirfile) [next]: Remove member. 2097 [length]: Add member. [impossible]: widen type to fill alignment gap. 2098 (dirfile_hash_1, dirfile_hash_2, dirfile_hash_cmp): New functions. 2099 (find_directory): Use new hash table package. 2100 (dir_contents_file_exists_p): Likewise. 2101 (file_impossible): Likewise. 2102 (file_impossible_p): Likewise. 2103 (print_dir_data_base): Likewise. 2104 (open_dirstream): Likewise. 2105 (read_dirstream): Likewise. 2106 (hash_init_directories): New function. 2107 2108 * file.c (hash.h): New #include. 2109 (file_hash_1, file_hash_2, file_hash_cmp): New functions. 2110 (files): Change type to `struct hash_table'. 2111 (lookup_file): Use new hash table package. 2112 (enter_file): Likewise. 2113 (remove_intermediates): Likewise. 2114 (snap_deps): Likewise. 2115 (print_file_data_base): Likewise. 2116 2117 * function.c 2118 (function_table_entry_hash_1, function_table_entry_hash_2, 2119 function_table_entry_hash_cmp): New functions. 2120 (lookup_function): Remove `table' argument. 2121 Use new hash table package. 2122 (struct a_word) [chain, length]: New members. 2123 (a_word_hash_1, a_word_hash_2, a_word_hash_cmp): New functions. 2124 (struct a_pattern): New struct. 2125 (func_filter_filterout): Pass through patterns noting boundaries 2126 and '%', if present. Note a_word length. Use a hash table if 2127 arglists are large enough to justify cost. 2128 (function_table_init): Renamed from function_table. 2129 (function_table): Declare as `struct hash_table'. 2130 (FUNCTION_TABLE_ENTRIES): New constant. 2131 (hash_init_function_table): New function. 2132 2133 * read.c (hash.h): New #include. 2134 (read_makefile): Pass char constants to find_char_unquote. 2135 (dep_hash_1, dep_hash_2, dep_hash_cmp): New functions. 2136 (uniquize_deps): Use hash table to efficiently identify duplicates. 2137 (find_char_unquote): Accept two char-constant stop chars, rather 2138 than a string constant, avoiding zillions of calls to strchr. 2139 Tighten inner search loops to test only for desired delimiters. 2140 2141 * variable.c (variable_hash_1, variable_hash_2, 2142 variable_hash_cmp): New functions. 2143 (variable_table): Declare as `struct hash_table'. 2144 (global_variable_set): Remove initialization. 2145 (init_hash_global_variable_set): New function. 2146 (define_variable_in_set): Use new hash table package. 2147 (lookup_variable): Likewise. 2148 (lookup_variable_in_set): Likewise. 2149 (initialize_file_variables): Likewise. 2150 (pop_variable_scope): Likewise. 2151 (create_new_variable_set): Likewise. 2152 (merge_variable_sets): Likewise. 2153 (define_automatic_variables): Likewise. 2154 (target_environment): Likewise. 2155 (print_variable_set): Likewise. 2156 21572002-07-10 Paul D. Smith <psmith@gnu.org> 2158 2159 Implement the SysV make syntax $$@, $$(@D), and $$(@F) in the 2160 prerequisite list. A real SysV make will expand the entire 2161 prerequisites list _twice_: we don't do that as it's a big 2162 backward-compatibility problem. We only replace those specific 2163 variables. 2164 2165 * read.c (record_files): Replace any $@, $(@D), and $(@F) variable 2166 references left in the list of prerequisites. Check for .POSIX as 2167 we record targets, so we can disable non-POSIX behavior while 2168 reading makefiles as well as running them. 2169 (eval): Check the prerequisite list to see if we have anything 2170 that looks like a SysV prerequisite variable reference. 2171 21722002-07-09 Paul D. Smith <psmith@gnu.org> 2173 2174 * doc/make.texi (Prerequisite Types): Add a new section describing 2175 order-only prerequisites. 2176 2177 * read.c (uniquize_deps): If we have the same file as both a 2178 normal and order-only prereq, get rid of the order-only prereq, 2179 since the normal one supersedes it. 2180 21812002-07-08 Paul D. Smith <psmith@gnu.org> 2182 2183 * AUTHORS: Added Greg McGary to the AUTHORS file. 2184 * NEWS: Blurbed order-only prerequisites. 2185 * file.c (print_file): Show order-only deps properly when printing 2186 the database. 2187 2188 * maintMakefile: Add "update" targets for wget'ing the latest 2189 versions of various external files. Taken from Makefile.maint in 2190 autoconf, etc. 2191 2192 * dosbuild.bat: Somehow we got _double_ ^M's. Remove them. 2193 Reported by Eli Zaretskii <eliz@is.elta.co.il>. 2194 21952002-07-07 Paul D. Smith <psmith@gnu.org> 2196 2197 * po/*.po: Remove. We'll use wget to retrieve them at release 2198 time. 2199 2200 * variable.c (do_variable_definition) [W32]: On W32 using cmd 2201 rather than a shell you get an exception. Make sure we look up 2202 the variable. Patch provided by Eli Zaretskii <eliz@is.elta.co.il>. 2203 2204 * remake.c (notice_finished_file): Fix handling of -t flag. 2205 Patch provided by Henning Makholm <henning@makholm.net>. 2206 2207 * implicit.c (pattern_search): Some systems apparently run short 2208 of stack space, and using alloca() in this function caused an 2209 overrun. I modified it to use xmalloc() on the two variables 2210 which seemed like they might get large. Fixes Bug #476. 2211 2212 * main.c (print_version): Update copyright notice to conform with 2213 GNU standards. 2214 (print_usage): Update help output. 2215 2216 * function.c (func_eval): Create a new make function, $(eval 2217 ...). Expand the arguments, put them into a buffer, then invoke 2218 eval_buffer() on the resulting string. 2219 (func_quote): Create a new function, $(quote VARNAME). Inserts 2220 the value of the variable VARNAME without expanding it any 2221 further. 2222 2223 * read.c (struct ebuffer): Change the linebuffer structure to an 2224 "eval buffer", which can be either a file or a buffer. 2225 (eval_makefile): Move the code in the old read_makefile() which 2226 located a makefile into here: create a struct ebuffer with that 2227 information. Have it invoke the new function eval() with that 2228 ebuffer. 2229 (eval_buffer): Create a new function that creates a struct ebuffer 2230 that holds a string buffer instead of a file. Have it invoke 2231 eval() with that ebuffer. 2232 (eval): New function that contains the guts of the old 2233 read_makefile() function: this function parses makefiles. Obtains 2234 data to parse from the provided ebuffer. Some modifications to 2235 make the flow of the function cleaner and clearer. Still could 2236 use some work here... 2237 (do_define): Takes a struct ebuffer instead of a FILE*. Read the 2238 contents of the define/endef variable from the ebuffer. 2239 (readstring): Read the next line from a string-style ebuffer. 2240 (readline): Read the next line from an ebuffer. If it's a string 2241 ebuffer, invoke readstring(). If it's a FILE* ebuffer, read it 2242 from the file. 2243 2244 * dep.h (eval_buffer): Prototype eval_buffer(); 2245 2246 * variable.c (do_variable_definition): Make sure that all 2247 non-target-specific variables are registered in the global set. 2248 If we're invoked from an $(eval ...) we might be inside a $(call 2249 ...) or other function which has pushed a variable scope; we still 2250 want to define our variables from evaluated makefile code in the 2251 global scope. 2252 22532002-07-03 Greg McGary <greg@mcgary.org> 2254 2255 * dep.h (struct dep) [ignore_mtime]: New member. 2256 [changed]: convert to a bitfield. 2257 * implicit.c (pattern_search): Zero ignore_mtime. 2258 * main.c (main, handle_non_switch_argument): Likewise. 2259 * rule.c (convert_suffix_rule): Likewise. 2260 * read.c (read_all_makefiles, read_makefile, multi_glob): Likewise. 2261 (read_makefile): Parse '|' in prerequisite list. 2262 (uniquize_deps): Consider ignore_mtime when comparing deps. 2263 * remake.c (update_file_1, check_dep): Don't force remake for 2264 dependencies that have d->ignore_mtime. 2265 * commands.c (FILE_LIST_SEPARATOR): New constant. 2266 (set_file_variables): Don't include a 2267 prerequisite in $+, $^ or $? if d->ignore_mtime. 2268 Define $|. 2269 22702002-06-18 Paul D. Smith <psmith@gnu.org> 2271 2272 * make.texinfo: Updates for next revision. New date/rev/etc. 2273 Recreate all Info menus. Change license on the manual to the GNU 2274 Free Documentation License. A number of typos. 2275 (Variables Simplify): Don't use "-" before it's defined. 2276 (Automatic Prerequisites): Rewrite the target example to work 2277 properly if the compile fails. Remove incorrect comments about 2278 how "set -e" behaves. 2279 (Text Functions): Move the "word", "wordlist", "words", and 2280 "firstword" functions here, from "File Name Functions". 2281 * make-stds.texi: Update from latest GNU version. 2282 * fdl.texi: (created) Import the latest GNU version. 2283 22842002-06-06 Paul D. Smith <psmith@gnu.org> 2285 2286 * variable.c (do_variable_definition): New function: extract the 2287 part of try_variable_definition() that actually sets the value 2288 into a separate function. 2289 (try_variable_definition): Call do_variable_definition() after 2290 parsing the variable definition string. 2291 (define_variable_in_set): Make the name argument const. 2292 2293 * variable.h (enum variable_flavor): Make public. 2294 (do_variable_definition): Create prototype. 2295 2296 * read.c (read_all_makefiles): Create a new built-in variable, 2297 MAKEFILE_LIST. 2298 (read_makefile): Add each makefile read in to this variable value. 2299 23002002-05-18 Eli Zaretskii <eliz@is.elta.co.il> 2301 2302 * Makefile.DOS.template: Tweak according to changes in the 2303 distribution. Add back the dependencies of *.o files. 2304 2305 * configh.dos.template: Synchronize with config.h.in. 2306 23072002-05-09 Paul D. Smith <psmith@gnu.org> 2308 2309 * file.c (file_timestamp_now): Use K&R function declaration. 2310 2311 * getloadavg.c (getloadavg): Merge setlocale() fix from sh-utils 2312 getloadavg.c. Autoconf thinks QNX is SVR4-like, but it isn't, so 2313 #undef it. Remove predefined setup of NLIST_STRUCT. Decide 2314 whether to include nlist.h based on HAVE_NLIST_H. Change obsolete 2315 NLIST_NAME_UNION to new HAVE_STRUCT_NLIST_N_UN_N_NAME. 2316 * configure.in (NLIST_STRUCT): Define this if we have nlist.h and 2317 nlist.n_name is a pointer rather than an array. 2318 2319 * acinclude.m4 (make_FUNC_SETVBUF_REVERSED): Grab the latest 2320 version of AC_FUNC_SETVBUF_REVERSED from autoconf CVS. 2321 * configure.in: Use it instead of the old version. 2322 2323 * main.c (main): Prefer setvbuf() to setlinebuf(). 2324 23252002-05-08 Paul D. Smith <psmith@gnu.org> 2326 2327 * Makefile.am (make_LDADD): Add GETLOADAVG_LIBS. 2328 (loadavg_LDADD): Ditto. 2329 23302002-04-29 Paul D. Smith <psmith@gnu.org> 2331 2332 * expand.c (recursively_expand_for_file): Rename 2333 recursively_expand() to recursively_expand_for_file() and provide 2334 an extra argument, struct file. If the argument is provided, set 2335 the variable scope to that of the file before expanding. 2336 * variable.h (recursively_expand): Make this a macro that invokes 2337 recursively_expand_for_file() with a NULL file pointer. 2338 * variable.c (target_environment): Call the renamed function and 2339 provide the current file context. 2340 Fixes Debian bug #144306. 2341 23422002-04-28 Paul D. Smith <psmith@gnu.org> 2343 2344 Allow $(call ...) user-defined variables to be self-referencing 2345 without throwing an error. Allows implementation of transitive 2346 closures, among other possibly useful things. 2347 Requested by: Philip Guenther <guenther@sendmail.com> 2348 2349 * variable.h (struct variable): Add a new field: exp_count, and 2350 new macros to hold its size and maximum value. 2351 (warn_undefined): Make this a macro. 2352 * variable.c (define_variable_in_set): Initialize it. 2353 * expand.c (recursively_expand): If we detect recursive expansion 2354 of a variable, check the exp_count field. If it's greater than 0 2355 allow the recursion and decrement the count. 2356 (warn_undefined): Remove this (now a macro in variable.h). 2357 * function.c (func_call): Before we expand the user-defined 2358 function, modify its exp_count field to contain the maximum 2359 number of recursive calls we'll allow. After the call, reset it 2360 to 0. 2361 23622002-04-21 Paul D. Smith <psmith@gnu.org> 2363 2364 Modified to use latest autoconf (2.53), automake (1.6.1), and 2365 gettext (0.11.1). We're using gettext's new "external" support, 2366 to avoid including libintl source with GNU make. 2367 2368 * README.cvs: New file. Explain how to build GNU make from CVS. 2369 2370 * configure.in: Modify checking for the system glob library. 2371 Use AC_EGREP_CPP instead of AC_TRY_CPP. Remove the setting of 2372 GLOBDIR (we will always put "glob" in SUBDIRS, so automake 2373 etc. will manage it correctly). Set an automake conditional 2374 USE_LOCAL_GLOB to decide whether to compile the glob library. 2375 2376 * getloadavg.c (main): Include make.h in the "TEST" program to 2377 avoid warnings. 2378 2379 * Makefile.am: Remove special rules for loadavg. Replace them 2380 with Automake capabilities for building extra programs. 2381 2382 * signame.c: This file does nothing if the system provide 2383 strsignal(). If not, it implements strsignal(). If the system 2384 doesn't define sys_siglist, then we make our own; otherwise we use 2385 the system version. 2386 * signame.h: Removed. 2387 2388 * main.c (main): No need to invoke signame_init(). Update copyright. 2389 2390 * ABOUT-NLS: Removed. 2391 * gettext.c: Removed. 2392 * gettext.h: Get a simplified copy from the gettext package. 2393 * po/*: Created. 2394 * i18n/*.po: Moved to po/. 2395 * i18n/: Removed. 2396 2397 * config/*: Created. Contains package configuration helper files. 2398 * config.guess, config.sub: Moved to config directory. 2399 2400 * configure.in (AC_CONFIG_FILES): Add po/Makefile.in, config/Makefile. 2401 Rework to use new-style autoconf features. Use the "external" 2402 mode for gettext. Make the build.sh config file conditional on 2403 whether build.sh.in exists, to avoid autoconf errors. 2404 * acinclude.m4: Removed almost all macros as being obsolete. 2405 Rewrote remaining macros to use AC_DEFINE. 2406 * acconfig.h: Removed. 2407 2408 * Makefile.am (EXTRA_DIST): Add config/config.rpath. Use a 2409 conditional to handle customs support. Remove special handling 2410 for i18n features. 2411 24122002-04-20 Paul D. Smith <psmith@gnu.org> 2413 2414 * function.c (func_call): Don't mark the argument variables $1, 2415 etc. as recursive. They've already been fully expanded so 2416 there's no need to do it again, and doing so strips escaped $'s. 2417 Reported by Sebastian Glita <glseba@yahoo.com>. 2418 2419 * remake.c (notice_finished_file): Walk through double-colon 2420 entries via the prev field, not the next field! 2421 Reported by Greg McGary <greg@mcgary.org>. 2422 2423 * main.c (main): If the user specifies -q and asks for a specific 2424 target which is a makefile, we got an assert. In that case it 2425 turns out we should continue normally instead. 2426 2427 * i18n/de.po, i18n/fr.po: Installed an updated translation. 2428 2429 * i18n/he.po: Installed a new translation. 2430 24312002-01-07 Paul D. Smith <psmith@gnu.org> 2432 2433 * i18n/es.po, i18n/ru.po: Installed an updated translation. 2434 24352001-12-04 Paul D. Smith <psmith@gnu.org> 2436 2437 * i18n/ja.po: Installed an updated translation. 2438 24392001-09-06 Paul Eggert <eggert@twinsun.com> 2440 2441 * configure.in (AC_CHECK_HEADERS): Add sys/resource.h. 2442 (AC_CHECK_FUNCS): Add getrlimit, setrlimit. 2443 2444 * main.c: Include <sys/resource.h> if it, getrlimit, and setrlimit 2445 are available. 2446 (main): Get rid of any avoidable limit on stack size. 2447 24482001-09-04 Paul D. Smith <psmith@gnu.org> 2449 2450 * i18n/da.po: Installed an updated translation. 2451 24522001-08-03 Paul D. Smith <psmith@gnu.org> 2453 2454 * i18n/fr.po: Installed an updated translation. 2455 Resolves Debian bug #106720. 2456 24572001-06-13 Paul D. Smith <psmith@gnu.org> 2458 2459 * i18n/da.po, configure.in (ALL_LINGUAS): Installed a new 2460 translation. 2461 24622001-06-11 Paul D. Smith <psmith@gnu.org> 2463 2464 * i18n/ko.po: Installed a new translation. 2465 24662001-05-06 Paul D. Smith <psmith@gnu.org> 2467 2468 Modify the EINTR handling. 2469 2470 * job.c (new_job): Reorganize the jobserver algorithm. Reorder 2471 the way in which we manage the file descriptor/signal handler race 2472 trap to be more efficient. 2473 24742001-05-06 Paul Eggert <eggert@twinsun.com> 2475 2476 Restart almost all system calls that are interrupted, instead 2477 of worrying about EINTR. The lone exception is the read() for 2478 job tokens. 2479 2480 * configure.in (HAVE_SA_RESTART): New macro. 2481 (MAKE_JOBSERVER): Define to 1 only if HAVE_SA_RESTART. 2482 * main.c (main): Use SA_RESTART instead of the old, 2483 nonstandard SA_INTERRUPT. 2484 2485 * configure.in (AC_CHECK_FUNCS): Add bsd_signal. 2486 * main.c (bsd_signal): New function or macro, 2487 if the implementation doesn't supply it. 2488 (The bsd_signal function will be in POSIX 1003.1-200x.) 2489 (HANDLESIG): Remove. 2490 (main, FATAL_SIG): Use bsd_signal instead of signal or HANDLESIG. 2491 2492 * make.h (EINTR_SET): Remove. 2493 (SA_RESTART): New macro. 2494 2495 * arscan.c (ar_member_touch): Don't worry about EINTR. 2496 * function.c (func_shell): Likewise. 2497 * job.c (reap_children, free_child, new_job): Likewise. 2498 * main.c (main): Likewise. 2499 * remake.c (touch_file, name_mtime): Likewise. 2500 2501 * arscan.c (ar_member_touch): Fix bug uncovered by EINTR removal; 2502 if fstat failed with errno!=EINTR, the error was ignored. 2503 2504 * job.c (set_child_handler_action_flags): New function. 2505 (new_job): Use it to temporarily clear the SIGCHLD action flags 2506 while reading the token. 2507 25082001-05-02 Paul D. Smith <psmith@gnu.org> 2509 2510 * job.c (start_job_command): Don't add define/endef per-line flags 2511 to the top-level flags setting. 2512 25132001-04-03 Paul D. Smith <psmith@gnu.org> 2514 2515 * arscan.c (VMS_get_member_info,ar_scan) [VMS]: VMS sets the low 2516 bit on error, so check for odd return values, not non-0 return 2517 values. 2518 (VMS_get_member_info): Calculate the timezone differences correctly. 2519 Reported by John Fowler <jfowler@nyx.net>. 2520 2521 25222001-03-14 Paul D. Smith <psmith@gnu.org> 2523 2524 * variable.c (lookup_variable) [VMS]: Null-terminate the variable 2525 value before invoking define_variable(). 2526 Reported by John Fowler <jfowler@nyx.net>. 2527 25282001-02-07 Paul D. Smith <psmith@gnu.org> 2529 2530 * read.c (record_target_var): If we reset the variable due to a 2531 command-line variable setting overriding it, turn off the "append" 2532 flag. 2533 25342001-01-17 Paul D. Smith <psmith@gnu.org> 2535 2536 * variable.c (lookup_variable) [VMS]: When getting values from the 2537 environment, allocate enough space for the _value_ plus escapes, 2538 not enough space for the name plus escapes :-/. 2539 Reported by John Fowler <jfowler@nyx.net>. 2540 2541 * remake.c (f_mtime): Removed the "***" prefix from the mod time 2542 warnings that make generates, so it doesn't look like an error. 2543 Reported by Karl Berry <karl@gnu.org>. 2544 2545 2546 Fix for PR/2020: Rework appended target-specific variables. I'm 2547 fairly confident this algorithm is finally correct. 2548 2549 * expand.c (allocated_variable_append): Rewrite. Instead of 2550 expanding each appended variable then adding all the expanded 2551 strings together, we append all the unexpanded values going up 2552 through the variable set contexts, then expand the final result. 2553 This behaves just like non-target-specific appended variable 2554 values, while the old way didn't in various corner cases. 2555 (variable_append): New function: recursively append the unexpanded 2556 value of a variable, walking from the outermost variable scope to 2557 the innermost. 2558 * variable.c (lookup_variable): Remove the code that looked up the 2559 variable set list if the found variable was "append". We don't 2560 need this anymore. 2561 (lookup_variable_in_set): Make this non-static so we can use it 2562 elsewhere. 2563 (try_variable_definition): Use lookup_variable_in_set() rather 2564 than faking out current_variable_set_list by hand (cleanup). 2565 * variable.h: Add a prototype for the now non-static 2566 lookup_variable_in_set(). 2567 25682000-11-17 Paul D. Smith <psmith@gnu.org> 2569 2570 * remake.c (f_mtime) [WINDOWS32]: On various advice, I changed the 2571 WINDOWS32 port to assume timestamps can be up to 3 seconds away 2572 before throwing a fit. 2573 25742000-11-17 Paul D. Smith <psmith@gnu.org> 2575 2576 * read.c (readline): CRLF calculations had a hole, if you hit the 2577 buffer grow scenario just right. Reworked the algorithm to avoid 2578 the need for len or lastlen at all. Problem description with 2579 sample code chages provided by Chris Faylor <cgf@redhat.com>. 2580 25812000-10-24 Paul D. Smith <psmith@gnu.org> 2582 2583 * gettext.c (SWAP): Declare this with the prototype, otherwise 2584 some systems don't work (non-32-bit? Reported for Cray T3E). 2585 Reported by Thorstein Thorsteinsson <thor@signe.teokem.lu.se>. 2586 25872000-10-05 Paul D. Smith <psmith@gnu.org> 2588 2589 * acinclude.m4 (AM_LC_MESSAGES): Remove undefined macro 2590 AM_LC_MESSAGES; it doesn't seem to do anything anyway?? 2591 2592 * i18n/gl.po, configure.in (ALL_LINGUAS): New Galician translation. 2593 25942000-09-22 Paul D. Smith <psmith@gnu.org> 2595 2596 * gettext.c: Don't #define _GETTEXT_H here; we only include some 2597 parts of the real gettext.h here, and we expect to really include 2598 the real gettext.h later. If we keep this #define, it's ignored. 2599 26002000-09-21 Paul D. Smith <psmith@gnu.org> 2601 2602 * main.c (log_working_directory): Rework the text to use complete 2603 sentences, to make life simpler for the translators. 2604 26052000-08-29 Paul D. Smith <psmith@gnu.org> 2606 2607 * file.c (remove_intermediates): Print a debug message before we 2608 remove intermediate files, so the user (if she uses -d) knows 2609 what's going on. 2610 26112000-08-21 Paul D. Smith <psmith@gnu.org> 2612 2613 * variable.c (try_variable_definition): Change how we handle 2614 target-specific append variable defns: instead of just setting the 2615 value, expand it as an append _but_ only within the current 2616 target's context. Otherwise we lose all but the last value if the 2617 variable is appended more than once within the current target 2618 context. Fixes PR/1831. 2619 26202000-08-16 Paul D. Smith <psmith@gnu.org> 2621 2622 * function.c (func_shell): Nul-terminate the buffer before 2623 printing an exec error message (just in case it's not!). 2624 Fixes PR/1860, reported by Joey Hess <joey@valinux.com>. 2625 26262000-07-25 Paul D. Smith <psmith@gnu.org> 2627 2628 * job.c (construct_command_argv_internal): Add "~" to the list of 2629 sh_chars[] which disallow optimizing out the shell call. 2630 26312000-07-23 Paul Eggert <eggert@twinsun.com> 2632 2633 * NEWS, make.texinfo: Document .LOW_RESOLUTION_TIME, which 2634 supersedes --disable-nsec-timestamps. 2635 * make.texinfo: Consistently use "time stamp" instead of "timestamp". 2636 * README: Remove --disable-nsec-timestamps. 2637 2638 * filedef.h (struct file.low_resolution_time): New member. 2639 * file.c (snap_deps): Add support for .LOW_RESOLUTION_TIME. 2640 * remake.c (update_file_1): 2641 Avoid spurious rebuilds due to low resolution time stamps, 2642 generalizing the earlier code that applied only to archive members. 2643 (f_mtime): Archive members always have low resolution time stamps. 2644 2645 * configure.in: Remove --disable-nsec-timestamps, as this has 2646 been superseded by .LOW_RESOLUTION_TIME. 2647 26482000-07-23 Paul Eggert <eggert@twinsun.com> 2649 2650 * configure.in (enable_nsec_timestamps): Renamed from 2651 make_cv_nsec_timestamps, since enable/disable options 2652 shouldn't be cached. 2653 26542000-07-23 Bruno Haible <haible@clisp.cons.org> 2655 and Paul Eggert <eggert@twinsun.com> 2656 2657 * file.c (file_timestamp_now): 2658 Use preprocessor-time check for FILE_TIMESTAMP_HI_RES 2659 so that clock_gettime is not linked unless needed. 2660 2661 * filedef.h (FILE_TIMESTAMP_HI_RES): 2662 Remove definition; "configure" now does this. 2663 2664 * configure.in (jm_AC_TYPE_UINTMAX_T): Move up, 2665 to before high resolution file timestamp check, 2666 since that check now uses uintmax_t. 2667 (FILE_TIMESTAMP_HI_RES): Define to nonzero if the code should use 2668 high resolution file timestamps. 2669 (HAVE_CLOCK_GETTIME): Do not define if !FILE_TIMESTAMP_HI_RES, 2670 so that we don't link in clock_gettime unnecessarily. 2671 26722000-07-17 Paul D. Smith <psmith@gnu.org> 2673 2674 * i18n/ja.po: New version of the translation file. 2675 26762000-07-07 Paul D. Smith <psmith@gnu.org> 2677 2678 * remake.c (f_mtime): If NO_FLOAT is defined, don't bother with 2679 the offset calculation. 2680 (name_mtime): Replace EINTR test with EINTR_SET macro. 2681 26822000-07-07 Paul Eggert <eggert@twinsun.com> 2683 2684 Fix for PR/1811: 2685 2686 * remake.c (update_file_1): 2687 Avoid spurious rebuilds of archive members due to their 2688 timestamp resolution being only one second. 2689 (f_mtime): Avoid spurious warnings of timestamps in the future due to 2690 the clock's resolution being lower than file timestamps'. 2691 When warning about future timestamps, report only the discrepancy, 2692 not the absolute value of the timestamp and the current time. 2693 2694 * file.c (file_timestamp_now): New arg RESOLUTION. 2695 * filedef.h (file_timestamp_now): Likewise. 2696 (FILE_TIMESTAMP_NS): Now returns int. All uses changed. 2697 26982000-07-05 Paul D. Smith <psmith@gnu.org> 2699 2700 * variable.c (lookup_variable) [VMS]: Remove vestigial references 2701 to listp. Fixes PR/1793. 2702 27032000-06-26 Paul Eggert <eggert@twinsun.com> 2704 2705 * Makefile.am (MAINTAINERCLEANFILES): New macro, with stamp-pot in it. 2706 2707 * dir.c (vms_hash): Ensure ctype macro args are nonnegative. 2708 2709 * remake.c (f_mtime): Remove unused var memtime. 2710 27112000-06-25 Martin Buchholz <martin@xemacs.org> 2712 2713 * make.texinfo, NEWS, TODO.private: Minor spelling corrections. 2714 Ran spell-check on make.texinfo. 2715 27162000-06-23 Paul D. Smith <psmith@gnu.org> 2717 2718 * main.c (main): Replace EXIT_SUCCESS, EXIT_FAILURE, and 2719 EXIT_TROUBLE with MAKE_SUCCESS, MAKE_FAILURE, and MAKE_TROUBLE. 2720 * make.h: Define these macros. 2721 2722 * Version 3.79.1 released. 2723 2724 * configure.in: Add a new option, --disable-nsec-timestamps, to 2725 avoid using sub-second timestamps on systems that support it. It 2726 can lead to problems, e.g. if your makefile relies on "cp -p". 2727 * README.template: Document the issue with "cp -p". 2728 2729 * config.guess, config.sub: Updated. 2730 2731 2732 2733See ChangeLog.2, available in the CVS repository at: 2734 2735 http://savannah.gnu.org/cvs/?group=make 2736 2737for earlier changes. 2738 2739 2740Copyright (C) 2000, 2001, 2002, 2003, 2004, 2005, 2006 Free Software 2741Foundation, Inc. 2742This file is part of GNU Make. 2743 2744GNU Make is free software; you can redistribute it and/or modify it under the 2745terms of the GNU General Public License as published by the Free Software 2746Foundation; either version 2, or (at your option) any later version. 2747 2748GNU Make is distributed in the hope that it will be useful, but WITHOUT ANY 2749WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR 2750A PARTICULAR PURPOSE.
