insert() was trying to be too clever, and it would end up delaying
the media scanner until the next download happened. This resulted
in duplicate photos in DocumentsUI.

Add column to mark downloads as being writable, and allow documents
to be created under Downloads backend. Update database when writing
is finished, and generate unique filenames when they already exist.

Check canonical path on incoming _DATA paths.

1d0a0aa2cc5bfed8107aa70f7e890fde9a7ea2b4 30-Jan-2013 Jeff Sharkey <jsharkey@android.com> Dump recent downloads from provider.

The lifetime of DownloadService can be limited, and it's often
missing from bugreports. The provider has a much longer lifetime,
so have it dump raw data about recent downloads.

Now the final errors are always thrown, and the outer code decides
how to handle them as retries. Also clean up method signatures.

Switch to using new inbox-style notifications when collapsing multiple
downloads. Correctly handles clustering, including cancellation of
stale notifications. All notifications are now handled in a single
class, making it easier to reason about correctness.

Fixed bugs around handling of visibility flags. Move away from using
"int" as internal keys, since they can overflow. Started work for
time estimates, will finish in a future CL.

Explicitly pass all relevant IDs to DownloadReceiver instead of doing
a second racy query. Fix StrictMode warnings when querying in
DownloadReceiver.

new API where DownloadInfo.getAllDownloadsUri() is accessible, make any

gingerbread.
High-level details
1. When a file is downloaded by DownloadManager, metadata about the file
is stored in 2 databases: DownloadProvider and MediaProvider.

2. So, when it is to be deleted, its metadata needs to be cleaned up from
both the databases.

3. But the 2 databases use differnt content-uri's as "primary keys" and
DownloadProvider loses the "primary-key" of the row in MediaProvider
database.

4. Easiest thing would have been to have DownloadProvider give filepath
to MediaProvider and let MediaProvider linearly scan its database
to locate the row and delete it.

5. The other - faster but more coding for now - option is to have
DownloadProvider store the "primary-key" of the MediaProvider's
row. implemented in this CL.

Low-level details
1. add 2 new columns to downloads table in downloads.db:
mediaprovider_uri = downloaded file's content_uri in mediaprovider db
this column is null for downloads that finished before this column is
added to the database.
deleted = flag is set to true if a file is to be deleted
2. download UI app shows only those files whose 'deleted' flag is not set.
3. when the user deletes downloads from download UI app,
3.1. if mediaprovider_uri is NOT null, then the row is deleted from
downloads table AND from the mediaprovider database.
3.2 if mediaprovider_uri is NULL, then its row in downloads database
is marked 'tp be deleted' by setting 'deleted' column to '1'.
4. When DownloadService (in DownloadProvider) processes all rows from
downloads table, if it sees any rows wth 'deleted' = 1, then
it uses MediaScanner Service to re-scan the file,
get the mediaprovider_uri from MediaProvider
and update the row in downloads table with this mediaprovider_uri value
and then delete the row by doing the following
1. delete it from MediaProvider database using mediaprovider_uri
2. delete it from DownloadProvider database

Problem with this solution:
There is a small window where it is deleted by the user on the Download app
(and the row disappears from the display) but it is still present in
Gallery app.
Thats due to the following asynchronous operations
1. DownladService which processes rows-to-be-deleted is not always up
2. DownloadService uses asynchronous call to have the file re-scanned
by MediaScanner to get mediaprovider_uri

The DownloadProvider now ensures that current bytes, total bytes,
title and description are never null in the DB. Some new code relies
on this assumption for simplicity. That means we need to ensure this
invariant is true for pre-existing downloads as well.

This change extends the original work to add a size limit over which
wifi is required to download a file.

First, this change adds a second size limit, over which wifi is
recommended but not required. The user has the option to bypass this
limit.

Second, this change implements dialogs shown to the user when either
limit is exceeded. These dialogs are shown by the background download
manager service when a download is started and found to be over the
limit (and wifi is not connected).

I'm including one small fix to the unit tests needed from the previous
change.

This change started out just fixing a few regressions related to
notifications:

* Browser downloads weren't picking up a title from the determined
filename. This was due to my change to default the title field to
"" instead of null.

* Notification click/hide events weren't being handled properly. This
was due to previous change to the URI structure of DownloadProvider.
DownloadReceiver needed to be changed to perform queries through
/all_downloads URIs, like all other parts of the download manager
code. I did some general refactoring of the DownloadReceiver code
while I was there.

* The code in DownloadNotification wasn't picking up some updates to
downloads properly. This was due to my change to make
DownloadNotification use the DownloadInfo objects rather than
querying the database directly, so that it could make use of info
provided by the DownloadThread that didn't go into the DB. Fixing
this didn't turn out to be all that complicated, but along the way
to figuring this out I made some substantial refactoring in
DownloadService which made it much cleaner anyway and eliminated a
lot of duplication. That's something that had to happen eventually,
so I'm leaving it all in.

New URI structure with "my_downloads" and "all_downloads"
3d55d829c03fe78ad8cdab119293efb6c6e49c64 13-Sep-2010 Steve Howard <showard@google.com> New URI structure with "my_downloads" and "all_downloads"

This change introduces a second view into the download manager
database via a set of URIs starting with /all_downloads, renaming the
original /download URIs to /my_downloads. In addition to making
things more clear, this change allows the downloads UI to grant
permissions on individual downloads to viewer apps.

The old semantics were:

* for ordinary callers, /download included only downloads initiated by
the calling UID
* for intraprocess calls or calls by root, /download included all
downloads

The new semantics are

* /my_downloads always includes only downloads initiated by the
calling UID, and requires only INTERNET permission. It could just
as well require no permission, but that's not possible in the
framework, since path-permissions can only broaden access, not
tighten it. It doesn't matter, because these URIs are useless
without INTERNET permission -- if a user can't initiate downloads,
there's no reason to read this.
* /all_downloads always includes all downloads on the system, and
requires the new permission ACCESS_ALL_DOWNLOADS. This permission
is currently protectionLevel=signature -- this could be relaxed
later to support third-party download managers.

All download manager code has been changed to use /all_downloads URIs,
except when passing a URI to another app. In making this change
across the download manager code, I've taken some liberties in
cleaning things up. Other apps are unchanged and will use
/my_downloads.

Finally, this incorporates changes to DownloadManager to return a
content URI for /cache downloads -- the download UI no longer assumes
it's a file URI, and it grants permissions to the receiver of the VIEW
intent. The public API test has also been updated.

I've also fixed some null cursor checking in DownloadManager.

This change makes all downloads through the public API visible by
default. It removes the API that had allowed applications to control
notifications while the download runs. This has been replaced with a
hidden API, since such behavior is needed by SystemUpdater and Market
(for self-updates). Additionally, the behavior is now protected by a
new permission.

I'm making this permission signatureOrSystem, and changing the
non-purgeable permission to the same (it should've been that, I just
didn't know). I'm also adding string descriptions to appease the
translation folks.

This change adds a permission,
android.permission.DOWNLOAD_CACHE_NON_PURGEABLE. When an app has this
permission, any downloads it requests through the public API to the
download cache will automatically become non-purgeable, i.e. they'll
never be automatically deleted by the download manager to free up
space. This is intended for use only by the system updater.

This change removes the requirement that apps have the
ACCESS_DOWNLOAD_MANAGER permission in order to access
DownloadProvider. This enables the public API to work. Instead,
DownloadProvider enforces the new permissions model for the public
API:
* insert() requires INTERNET permission
* insert() checks that input fits within the restricted input allowed
for the public API
* insert() also strictly checks the file URI provided with
DESTINATION_FILE_URI (and still requires WRITE_EXTERNAL_STORAGE
permission if that is supplied)

Note that if an app has the ACCESS_DOWNLOAD_MANAGER permission, legacy
behavior is retained.

I've added a test to cover this new access, and updated the existing
permissions tests.

I also fixed a bug in WHERE clause construction in update() and
delete(), and refactored the code to eliminate duplication.

I need to make COLUMN_URI readable by apps, since the public API
exposes that field. In order to avoid any possible security issues, I
got rid of the feature that potentially allowed apps to view downloads
from other UIDs. No one was using that feature and the public API
exposes no such feature (yet).

While at it, I cleaned up some related code in update() and delete().

* Change broadcast intent code to match public API spec, for public API downloads only. (Legacy code can go away once existing clients are converted over to the new API.)
* Introduce SystemFacade methods for sending broadcasts and checking package ownership; this facilitates new tests of broadcast code.
* Change DownloadInfo.canUseNetwork() to obey new connectivity controls available in public API, but again, retain legacy behavior for downloads initiated directly through DownloadProvider
* New test cases to cover the new behavior

Also made a couple changes to reduce some test flakiness I was observing:
* in tearDown(), wait for any running UpdateThread to complete
* in PublicApiFunctionalTest.setUp(), if the test directory already exists, remove it rather than aborting

Major refactoring of DownloadThread.run().
b5629da794cb3c1ca1970d206343743b165b9644 16-Jul-2010 Steve Howard <showard@google.com> Major refactoring of DownloadThread.run().

Motivation: I need to fix the handling of 302s, so that after a
disconnect, subsequent retries will use the original URI, not the
redirected one. Rather than store extra information in the DB, I'd
like to just keep the redirected URI in memory and make the redirected
request within the same DownloadThread. This involves working with
the large-scale structure of DownloadThread.run(). Since run() was a
~700 line method, I didn't feel comfortable making such changes.

So this change refactors run() into a ~80 line method which calls into
a collection of ~20 other short methods. The state previously kept in
local variables has been pulled into a couple of state-only inner
classes. The error-handling control flow, formerly handled by "break
http_request_loop" statements, is now handled by throwing a
"StopRequest" exception. The remaining structure of run() has been
simplified -- the outermost for loop, for example, could never
actually repeat and has been removed for now. Some other bits of code
have been cleaned up a bit, but the functionality has not been
modified.

There are many good next steps to this refactoring. Besides various
other cleanup bits, a major improvement would be to consolidate the
State/InnerState classes, move some functionality to this new class
(there are many functions of the form "void foo(State)" which would be
good candidates), and promote it to a top-level class. But I want to
take things one step at a time, and I think what I've got here is a
major improvement and should be enough to allow me to safely implement
the changes to redirection handling.

In the process of doing this refactoring I added many test cases to
PublicApiFunctionalTest to exercise some of the pieces of code I was
moving around. I also moved some test cases from
DownloadManagerFunctionalTest. Over time I'd like to move everything
over to use the PublicApiFunctionalTest approach, and then I may break
that into some smaller suites.

Other minor changes:
* use longs instead of ints to track file sizes, as these may be
getting quite large in the future
* provide a default DB value of -1 for COLUMN_TOTAL_BYTES, as this
simplifies some logic in DownloadThread
* small extensions to MockResponse to faciliate new test cases

Introduce a seam to ConnectivityManager and TelephonyManager
af28400b74de05862b470412a5c92f68e99f59f8 16-Jul-2010 Steve Howard <showard@google.com> Introduce a seam to ConnectivityManager and TelephonyManager

This change abstracts access to ConnectivityManager and
TelephonyManager behind methods on SystemFacade, moving the code from
Helpers into RealSystemFacade and adding fake implementations to
FakeSystemFacade. This facilitates new connectivity tests.

Merge commit 'd1bec343dcbbc555837790119449ff7eea7c5312'

* commit 'd1bec343dcbbc555837790119449ff7eea7c5312':
Support for custom HTTP headers on download requests
5224c6fbf20b4803a580ef449ab87ebfbbfedb78 14-Jul-2010 Steve Howard <showard@google.com> Support for custom HTTP headers on download requests

Provider changes:
* new many-to-one DB table holding headers for each download. since
there was no real migration logic in DownloadProvider, I implemented
some.
* DownloadProvider.insert() reads request headers out of the
ContentValues and puts them into the new table
* DownloadProvider.query() supports a new URI form,
download/#/headers, to fetch the headers associated with a download
* DownloadProvider.delete() removes request headers from this table

Service changes:
* made DownloadInfo store request headers upon initialization. While
I was at it, I refactored the initialization logic into DownloadInfo
to get rid of the massive 24-parameter constructor. The right next
step would be to move the update logic into DownloadInfo and merge
it with the initialization logic; however, I realized that headers
don't need to be updatable, and in the future, we won't need the
update logic at all, so i didn't bother touching the update code.
* made DownloadThread read headers from the DownloadInfo and include
them in the request; merged the custom Cookie and Referer logic into
this logic

Also added a couple new test cases for this stuff.

Merge commit '2c80c37546b89dfd31875f6f6e977e9610cdb22b'

Support for file URI destinations + last modified timestamp
6d9b98282c817b86a00f9c19a705da4cb19bc3a6 13-Jul-2010 Steve Howard <showard@google.com> Support for file URI destinations + last modified timestamp

File URI destinations:
* permission checking in DownloadProvider
* implementation in Helpers.generateSaveFile(). it's a fairly small
amount of logic added here, but I did some significant method
extraction to simplify this change and clean up the code in general.
* added test case

Last modified timestamp:
* made DownloadProvider use a SystemFacade for getting system time, so I could properly test timestamps
* updated test cases to cover last modified time + handle new ordering

applications to the SD card.

Necessary for http://b/issue?id=2384554

Also create names for files by default, so they do not display as
<Untitled>. Remove calls to createTitleFromFilename, which are
no longer necessary.

Requires a change to frameworks/base.

The public API is getting deeply reworked for forward compatibility,
but since the Download Manager and the Browser need to continue using
the old API, a separate copy is being kept on the side.

Fix crash in discardPurgeableFiles with proper selection syntax.

The basic crash is that this codepath was doing a query to the download
provider without properly quoting its selection arguments (which is
mandated by the download provider).

A secondary crash is that the DESTINATION column wasn't readable.

This fixes bug 1941125.

Tested by force-calling discardPurgeableFiles for each download
to /cache, locally adding a few debugging statements to be sure
that the codepath was getting executed, and doing a market download.
