Set thread names on FreeBSD
Also move the logic to shorten thread names from linux/Host.cpp to a new
SetShortThreadName as both FreeBSD and Linux need the functionality.

Fixed a case where the result of std::string's c_str() method was being called on a local variable and returned as a const char * incorrectly. We used to cache the thread names for threads in the current host process, but we shoudn't be caching that as the names can change over time, so now a std::string is returned from Host::GetThreadName().

Added a new host function that allows us to run shell command and get the output from them along with the status and signal:
Error
Host::RunShellCommand (const char *command,
const char *working_dir,
int *status_ptr,
int *signo_ptr,
std::string *command_output_ptr,
uint32_t timeout_sec);
This will allow us to use this functionality in the host lldb_private::Platform, and also use it in our lldb-platform binary. It leverages the existing code in Host::LaunchProcess and ProcessLaunchInfo.

We sometimes need to be able to call functions (via Process::RunThreadPlan) from code run on the private state thread. To do that we have to
spin up a temporary "private state thread" that will respond to events from the lower level process plugins. This check-in should work to do
that, but it is still buggy. However, if you don't call functions on the private state thread, these changes make no difference.
This patch also moves the code in the AppleObjCRuntime step-through-trampoline handler that might call functions (in the case where the debug
server doesn't support the memory allocate/deallocate packet) out to a safe place to do that call.

Full core file support has been added for mach-o core files.
Tracking modules down when you have a UUID and a path has been improved.
DynamicLoaderDarwinKernel no longer parses mach-o load commands and it
now uses the memory based modules now that we can load modules from memory.
Added a target setting named "target.exec-search-paths" which can be used
to supply a list of directories to use when trying to look for executables.
This allows one or more directories to be used when searching for modules
that may not exist in the SDK/PDK. The target automatically adds the directory
for the main executable to this list so this should help us in tracking down
shared libraries and other binaries.

Added code in the Host layer that can report system log messages
so that we don't have "fprintf (stderr, ...)" calls sprinkled everywhere.
Changed all needed locations over to using this.
For non-darwin, we log to stderr only. On darwin, we log to stderr _and_
to ASL (Apple System Log facility). This will allow GUI apps to have a place
for these error and warning messages to go, and also allows the command line
apps to log directly to the terminal.

Made the darwin host layer properly reap any child processes that it spawns.
After recent changes we weren't reaping child processes resulting in many
zombie processes.
This was fixed by adding more settings to the ProcessLaunchOptions class
that allow clients to specify a callback function and baton to be notified
when their process dies. If one is not supplied a default callback will be
used that "does the right thing".
Cleaned up a race condition in the ProcessGDBRemote class that would attempt
to monitor when debugserver died.
Added an extra boolean to the process monitor callbacks that indicate if a
process exited or not. If your process exited with a zero exit status and no
signal, both items could be zero.
Modified the process monitor functions to not require a callback function
in order to reap the child process.

Moved the execution context that was in the Debugger into
the CommandInterpreter where it was always being used.
Make sure that Modules can track their object file offsets correctly to
allow opening of sub object files (like the "__commpage" on darwin).
Modified the Platforms to be able to launch processes. The first part of this
move is the platform soon will become the entity that launches your program
and when it does, it uses a new ProcessLaunchInfo class which encapsulates
all process launching settings. This simplifies the internal APIs needed for
launching. I want to slowly phase out process launching from the process
classes, so for now we can still launch just as we used to, but eventually
the platform is the object that should do the launching.
Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able
to launch processes with all of the new eLaunchFlag settings. Modified any
code that was manually launching processes to use the Host::LaunchProcess
functions.
Fixed an issue where lldb_private::Args had implicitly defined copy
constructors that could do the wrong thing. This has now been fixed by adding
an appropriate copy constructor and assignment operator.
Make sure we don't add empty ModuleSP entries to a module list.
Fixed the commpage module creation on MacOSX, but we still need to train
the MacOSX dynamic loader to not get rid of it when it doesn't have an entry
in the all image infos.
Abstracted many more calls from in ProcessGDBRemote down into the
GDBRemoteCommunicationClient subclass to make the classes cleaner and more
efficient.
Fixed the default iOS ARM register context to be correct and also added support
for targets that don't support the qThreadStopInfo packet by selecting the
current thread (only if needed) and then sending a stop reply packet.
Debugserver can now start up with a --unix-socket (-u for short) and can
then bind to port zero and send the port it bound to to a listening process
on the other end. This allows the GDB remote platform to spawn new GDB server
instances (debugserver) to allow platform debugging.

Many improvements to the Platform base class and subclasses. The base Platform
class now implements the Host functionality for a lot of things that make
sense by default so that subclasses can check:
int
PlatformSubclass::Foo ()
{
if (IsHost())
return Platform::Foo (); // Let the platform base class do the host specific stuff
// Platform subclass specific code...
int result = ...
return result;
}
Added new functions to the platform:
virtual const char *Platform::GetUserName (uint32_t uid);
virtual const char *Platform::GetGroupName (uint32_t gid);
The user and group names are cached locally so that remote platforms can avoid
sending packets multiple times to resolve this information.
Added the parent process ID to the ProcessInfo class.
Added a new ProcessInfoMatch class which helps us to match processes up
and changed the Host layer over to using this new class. The new class allows
us to search for processs:
1 - by name (equal to, starts with, ends with, contains, and regex)
2 - by pid
3 - And further check for parent pid == value, uid == value, gid == value,
euid == value, egid == value, arch == value, parent == value.
This is all hookup up to the "platform process list" command which required
adding dumping routines to dump process information. If the Host class
implements the process lookup routines, you can now lists processes on
your local machine:
machine1.foo.com % lldb
(lldb) platform process list

The lldb-platform implements everything with the Host:: layer, so this should
"just work" for linux. I will probably be adding more stuff to the Host layer
for launching processes and attaching to processes so that this support should
eventually just work as well.
Modified the target to be able to be created with an architecture that differs
from the main executable. This is needed for iOS debugging since we can have
an "armv6" binary which can run on an "armv7" machine, so we want to be able
to do:
% lldb
(lldb) platform create remote-ios
(lldb) file --arch armv7 a.out
Where "a.out" is an armv6 executable. The platform then can correctly decide
to open all "armv7" images for all dependent shared libraries.
Modified the disassembly to show the current PC value. Example output:
(lldb) disassemble --frame
a.out`main:
0x1eb7: pushl %ebp
0x1eb8: movl %esp, %ebp
0x1eba: pushl %ebx
0x1ebb: subl $20, %esp
0x1ebe: calll 0x1ec3 ; main + 12 at test.c:18
0x1ec3: popl %ebx
-> 0x1ec4: calll 0x1f12 ; getpid
0x1ec9: movl %eax, 4(%esp)
0x1ecd: leal 199(%ebx), %eax
0x1ed3: movl %eax, (%esp)
0x1ed6: calll 0x1f18 ; printf
0x1edb: leal 213(%ebx), %eax
0x1ee1: movl %eax, (%esp)
0x1ee4: calll 0x1f1e ; puts
0x1ee9: calll 0x1f0c ; getchar
0x1eee: movl $20, (%esp)
0x1ef5: calll 0x1e6a ; sleep_loop at test.c:6
0x1efa: movl $12, %eax
0x1eff: addl $20, %esp
0x1f02: popl %ebx
0x1f03: leave
0x1f04: ret
This can be handy when dealing with the new --line options that was recently
added:
(lldb) disassemble --line
a.out`main + 13 at test.c:19
18 {
-> 19 printf("Process: %i\n\n", getpid());
20 puts("Press any key to continue..."); getchar();
-> 0x1ec4: calll 0x1f12 ; getpid
0x1ec9: movl %eax, 4(%esp)
0x1ecd: leal 199(%ebx), %eax
0x1ed3: movl %eax, (%esp)
0x1ed6: calll 0x1f18 ; printf
Modified the ModuleList to have a lookup based solely on a UUID. Since the
UUID is typically the MD5 checksum of a binary image, there is no need
to give the path and architecture when searching for a pre-existing
image in an image list.
Now that we support remote debugging a bit better, our lldb_private::Module
needs to be able to track what the original path for file was as the platform
knows it, as well as where the file is locally. The module has the two
following functions to retrieve both paths:
const FileSpec &Module::GetFileSpec () const;
const FileSpec &Module::GetPlatformFileSpec () const;

Did a lot more work on abtracting and organizing the platforms.
On Mac OS X we now have 3 platforms:
PlatformDarwin - must be subclassed to fill in the missing pure virtual funcs
but this implements all the common functionality between
remote-macosx and remote-ios. It also allows for another
platform to be used (remote-gdb-server for now) when doing
remote connections. Keeping this pluggable will allow for
flexibility.
PlatformMacOSX - Now implements both local and remote macosx desktop platforms.
PlatformRemoteiOS - Remote only iOS that knows how to locate SDK files in the
cached SDK locations on the host.
A new agnostic platform has been created:
PlatformRemoteGDBServer - this implements the platform using the GDB remote
protocol and uses the built in lldb_private::Host
static functions to implement many queries.

Added more platform support. There are now some new commands:
platform status -- gets status information for the selected platform
platform create <platform-name> -- creates a new instance of a remote platform
platform list -- list all available platforms
platform select -- select a platform instance as the current platform (not working yet)
When using "platform create" it will create a remote platform and make it the
selected platform. For instances for iPhone OS debugging on Mac OS X one can
do:
(lldb) platform create remote-ios --sdk-version=4.0
Remote platform: iOS platform
SDK version: 4.0
SDK path: "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0"
Not connected to a remote device.
(lldb) file ~/Documents/a.out
Current executable set to '~/Documents/a.out' (armv6).
(lldb) image list
[ 0] /Volumes/work/gclayton/Documents/devb/attach/a.out
[ 1] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/dyld
[ 2] /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.0/Symbols/usr/lib/libSystem.B.dylib
Note that this is all happening prior to running _or_ connecting to a remote
platform. Once connected to a remote platform the OS version might change which
means we will need to update our dependecies. Also once we run, we will need
to match up the actualy binaries with the actualy UUID's to files in the
SDK, or download and cache them locally.
This is just the start of the remote platforms, but this modification is the
first iteration in getting the platforms really doing something.

LLDB now has "Platform" plug-ins. Platform plug-ins are plug-ins that provide
an interface to a local or remote debugging platform. By default each host OS
that supports LLDB should be registering a "default" platform that will be
used unless a new platform is selected. Platforms are responsible for things
such as:
- getting process information by name or by processs ID
- finding platform files. This is useful for remote debugging where there is
an SDK with files that might already or need to be cached for debug access.
- getting a list of platform supported architectures in the exact order they
should be selected. This helps the native x86 platform on MacOSX select the
correct x86_64/i386 slice from universal binaries.
- Connect to remote platforms for remote debugging
- Resolving an executable including finding an executable inside platform
specific bundles (macosx uses .app bundles that contain files) and also
selecting the appropriate slice of universal files for a given platform.
So by default there is always a local platform, but remote platforms can be
connected to. I will soon be adding a new "platform" command that will support
the following commands:
(lldb) platform connect --name machine1 macosx connect://host:port
Connected to "machine1" platform.
(lldb) platform disconnect macosx
This allows LLDB to be well setup to do remote debugging and also once
connected process listing and finding for things like:
(lldb) process attach --name x<TAB>
The currently selected platform plug-in can now auto complete any available
processes that start with "x". The responsibilities for the platform plug-in

Made lldb_private::ArchSpec contain much more than just an architecture. It
now, in addition to cpu type/subtype and architecture flavor, contains:
- byte order (big endian, little endian)
- address size in bytes
- llvm::Triple for true target triple support and for more powerful plug-in
selection.

Cleaned up the dynamic library open/getsymbol/close code to use abstracted
flags such that symbols can be searched for within a shared library if desired.
Platforms that support the RTLD_FIRST flag can still take advantage of their
quicker lookups, and other platforms can still get the same fucntionality
with a little extra work.
Also changed LLDB_CONFIG flags over to either being defined, or not being
defined to stay in line with current open source practices and to prepare for
using autoconf or cmake to configure LLDB builds.

Modified the PluginManager to be ready for loading plug-ins from a system
LLDB plugin directory and a user LLDB plugin directory. We currently still
need to work out at what layer the plug-ins will be, but at least we are
prepared for plug-ins. Plug-ins will attempt to be loaded from the
"/Developer/Library/PrivateFrameworks/LLDB.framework/Resources/Plugins"
folder, and from the "~/Library/Application Support/LLDB/Plugins" folder on
MacOSX. Each plugin will be scanned for:
extern "C" bool LLDBPluginInitialize(void);
extern "C" void LLDBPluginTerminate(void);
If at least LLDBPluginInitialize is found, the plug-in will be loaded. The
LLDBPluginInitialize function returns a bool that indicates if the plug-in
should stay loaded or not (plug-ins might check the current OS, current
hardware, or anything else and determine they don't want to run on the current
host). The plug-in is uniqued by path and added to a static loaded plug-in
map. The plug-in scanning happens during "lldb_private::Initialize()" which
calls to the PluginManager::Initialize() function. Likewise with termination
lldb_private::Terminate() calls PluginManager::Terminate(). The paths for the
plug-in directories is fetched through new Host calls:
bool Host::GetLLDBPath (ePathTypeLLDBSystemPlugins, dir_spec);
bool Host::GetLLDBPath (ePathTypeLLDBUserPlugins, dir_spec);
This way linux and other systems can define their own appropriate locations
for plug-ins to be loaded.
To allow dynamic shared library loading, the Host layer has also been modified
to include shared library open, close and get symbol:
static void *
Host::DynamicLibraryOpen (const FileSpec &file_spec,
Error &error);
static Error
Host::DynamicLibraryClose (void *dynamic_library_handle);
static void *
Host::DynamicLibraryGetSymbol (void *dynamic_library_handle,
const char *symbol_name,
Error &error);
lldb_private::FileSpec also has been modified to support directory enumeration
in an attempt to abstract the directory enumeration into one spot in the code.
The directory enumertion function is static and takes a callback:
typedef enum EnumerateDirectoryResult
{
eEnumerateDirectoryResultNext, // Enumerate next entry in the current directory
eEnumerateDirectoryResultEnter, // Recurse into the current entry if it is a directory or symlink, or next if not
eEnumerateDirectoryResultExit, // Exit from the current directory at the current level.
eEnumerateDirectoryResultQuit // Stop directory enumerations at any level
};
typedef FileSpec::EnumerateDirectoryResult (*EnumerateDirectoryCallbackType) (void *baton,
FileSpec::FileType file_type,
const FileSpec &spec);
static FileSpec::EnumerateDirectoryResult
FileSpec::EnumerateDirectory (const char *dir_path,
bool find_directories,
bool find_files,
bool find_other,
EnumerateDirectoryCallbackType callback,
void *callback_baton);
This allow clients to specify the directory to search, and specifies if only
files, directories or other (pipe, symlink, fifo, etc) files will cause the
callback to be called. The callback also gets to return with the action that
should be performed after this directory entry. eEnumerateDirectoryResultNext
specifies to continue enumerating through a directory with the next entry.
eEnumerateDirectoryResultEnter specifies to recurse down into a directory
entry, or if the file is not a directory or symlink/alias to a directory, then
just iterate to the next entry. eEnumerateDirectoryResultExit specifies to
exit the current directory and skip any entries that might be remaining, yet
continue enumerating to the next entry in the parent directory. And finally
eEnumerateDirectoryResultQuit means to abort all directory enumerations at
all levels.
Modified the Declaration class to not include column information currently
since we don't have any compilers that currently support column based
declaration information. Columns support can be re-enabled with the
additions of a #define.
Added the ability to find an EmulateInstruction plug-in given a target triple
and optional plug-in name in the plug-in manager.
Fixed a few cases where opendir/readdir was being used, but yet not closedir
was being used. Soon these will be deprecated in favor of the new directory
enumeration call that was added to the FileSpec class.

Added a new variant of SBTarget::Launch() that deprectates the old one that
takes separate file handles for stdin, stdout, and stder and also allows for
the working directory to be specified.
Added support to "process launch" to a new option: --working-dir=PATH. We
can now set the working directory. If this is not set, it defaults to that
of the process that has LLDB loaded. Added the working directory to the
host LaunchInNewTerminal function to allows the current working directory
to be set in processes that are spawned in their own terminal. Also hooked this
up to the lldb_private::Process and all mac plug-ins. The linux plug-in had its
API changed, but nothing is making use of it yet. Modfied "debugserver" and
"darwin-debug" to also handle the current working directory options and modified
the code in LLDB that spawns these tools to pass the info along.
Fixed ProcessGDBRemote to properly pass along all file handles for stdin, stdout
and stderr.
After clearing the default values for the stdin/out/err file handles for
process to be NULL, we had a crasher in UserSettingsController::UpdateStringVariable
which is now fixed. Also fixed the setting of boolean values to be able to
be set as "true", "yes", "on", "1" for true (case insensitive) and "false", "no",
"off", or "0" for false.
Fixed debugserver to properly handle files for STDIN, STDOUT and STDERR that are not
already opened. Previous to this fix debugserver would only correctly open and dupe
file handles for the slave side of a pseudo terminal. It now correctly handles
getting STDIN for the inferior from a file, and spitting STDOUT and STDERR out to
files. Also made sure the file handles were correctly opened with the NOCTTY flag
for terminals.

Added the ability for a process to inherit the current host environment. This
was done as an settings variable in the process for now. We will eventually
move all environment stuff over to the target, but we will leave it with the
process for now. The default setting is for a process to inherit the host
environment. This can be disabled by setting the "inherit-env" setting to
false in the process.

Fixed a race condition that could cause ProcessGDBRemote::DoResume() to return
an error saying the resume timed out. Previously the thread that was trying
to resume the process would eventually call ProcessGDBRemote::DoResume() which
would broadcast an event over to the async GDB remote thread which would sent the
continue packet to the remote gdb server. Right after this was sent, it would
set a predicate boolean value (protected by a mutex and condition) and then the
thread that issued the ProcessGDBRemote::DoResume() would then wait for that
condition variable to be set. If the async gdb thread was too quick though, the
predicate boolean value could have been set to true and back to false by the
time the thread that issued the ProcessGDBRemote::DoResume() checks the boolean
value. So we can't use the predicate value as a handshake. I have changed the code
over to using a Event by having the GDB remote communication object post an
event:
GDBRemoteCommunication::eBroadcastBitRunPacketSent
This allows reliable handshaking between the two threads and avoids the erroneous
ProcessGDBRemote::DoResume() errors.
Added a host backtrace service to allow in process backtraces when trying to track
down tricky issues. I need to see if LLVM has any backtracing abilities abstracted
in it already, and if so, use that, but I needed something ASAP for the current issue
I was working on. The static function is:
void
Host::Backtrace (Stream &strm, uint32_t max_frames);
And it will backtrace at most "max_frames" frames for the current thread and can be
used with any of the Stream subclasses for logging.

Modified lldb_private::SymboleFile to be able to override where its TypeList
comes from by using a virtual function to provide it from the Module's
SymbolVendor by default. This allows the DWARF parser, when being used to
parse DWARF in .o files with a parent DWARF + debug map parser, to get its
type list from the DWARF + debug map parser so when we go and find full
definitions for types (that might come from other .o files), we can use the
type list from the debug map parser. Otherwise we ended up mixing clang types
from one .o file (say a const pointer to a forward declaration "class A") with
the a full type from another .o file. This causes expression parsing, when
copying the clang types from those parsed by the DWARF parser into the
expression AST, to fail -- for good reason. Now all types are created in the
same list.
Also added host support for crash description strings that can be set before
doing a piece of work. On MacOSX, this ties in with CrashReporter support
that allows a string to be dispalyed when the app crashes and allows
LLDB.framework to print a description string in the crash log. Right now this
is hookup up the the CommandInterpreter::HandleCommand() where each command
notes that it is about to be executed, so if we crash while trying to do this
command, we should be able to see the command that caused LLDB to exit. For
all other platforms, this is a nop.

Ok, last commit for the running processes in a new window. Now you can
optionally specify the tty you want to use if you want to use an existing
terminal window by giving a partial or full path name:
(lldb) process launch --tty=ttys002
This would find the terminal window (or tab on MacOSX) that has ttys002 in its
tty path and use it. If it isn't found, it will use a new terminal window.

Added a new Host call to find LLDB related paths:
static bool
Host::GetLLDBPath (lldb::PathType path_type, FileSpec &file_spec);
This will fill in "file_spec" with an appropriate path that is appropriate
for the current Host OS. MacOSX will return paths within the LLDB.framework,
and other unixes will return the paths they want. The current PathType
enums are:
typedef enum PathType
{
ePathTypeLLDBShlibDir, // The directory where the lldb.so (unix) or LLDB mach-o file in LLDB.framework (MacOSX) exists
ePathTypeSupportExecutableDir, // Find LLDB support executable directory (debugserver, etc)
ePathTypeHeaderDir, // Find LLDB header file directory
ePathTypePythonDir // Find Python modules (PYTHONPATH) directory
} PathType;
All places that were finding executables are and python paths are now updated
to use this Host call.
Added another new host call to launch the inferior in a terminal. This ability
will be very host specific and doesn't need to be supported on all systems.
MacOSX currently will create a new .command file and tell Terminal.app to open
the .command file. It also uses the new "darwin-debug" app which is a small
app that uses posix to exec (no fork) and stop at the entry point of the
program. The GDB remote plug-in is almost able launch a process and attach to
it, it currently will spawn the process, but it won't attach to it just yet.
This will let LLDB not have to share the terminal with another process and a
new terminal window will pop up when you launch. This won't get hooked up
until we work out all of the kinks. The new Host function is:
static lldb::pid_t
Host::LaunchInNewTerminal (
const char **argv, // argv[0] is executable
const char **envp,
const ArchSpec *arch_spec,
bool stop_at_entry,
bool disable_aslr);
Cleaned up FileSpec::GetPath to not use strncpy() as it was always zero
filling the entire path buffer.
Fixed an issue with the dynamic checker function where I missed a '$' prefix
that should have been added.

Cleaned up a unused member variable in Debugger.
Added the start of Host specific launch services, though it currently isn't
hookup up to anything. We want to be able to launch a process and use the
native launch services to launch an app like it would be launched by the
user double clicking on the app. We also eventually want to be able to run
a command line app in a newly spawned terminal to avoid terminal sharing.
Fixed an issue with the new DWARF forward type declaration stuff. A crasher
was found that was happening when trying to properly expand the forward
declarations.

Modified the host process monitor callback function Host::StartMonitoringChildProcess
to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which
could cause it to reap child processes that it shouldn't have.
Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new
approach will allow for partial parsing of the blocks within a function.

Change Target & Process so they can really be initialized with an invalid architecture.
Arrange that this then gets properly set on attach, or when a "file" is set.
Add a completer for "process attach -n".
Caveats: there isn't currently a way to handle multiple processes with the same name. That
will have to wait on a way to pass annotations along with the completion strings.
