* Add UI message when queued for wifi due to size.Steve Howard2010-08-201-0/+1
| | | | | | | | | | | | | | | | As it stands, when a download is paused because it's too big to proceed over mobile, and must proceed over wifi, it looks like any other paused download, with no indication of why it's paused. That may be passable for most other reasons for pausing a download, but it seems too confusing for this case. So this change adds a simple string message that replaces the progress bar when a download is paused for this reason (the icon also changes to a warning). The implementation isn't beautiful and could use some improvement, but I think it's acceptable and necessary. The exact UI design and wording are certainly open to change.

* Clean up error codes returned by download manager.Steve Howard2010-08-161-87/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | This set of changes cleans up the error codes returned by the download manager in various failure cases, aiming for improved consistency. Error codes are part of the public API so it's important to get this right now. The main changes here are: * Refactoring the flow of error status information throughout DownloadThread to make it more explicit, by having StopRequest accept a status code in its constructor and eliminating State.mFinaStatus. * Eliminating the use of valid HTTP 4xx statuses when those statuses weren't actually returned by the server. Now, if the returned error code is a valid HTTP status code, that means it was returned by the server. These cases have been replaced with more sensible artificial error codes, including a new ERROR_CANNOT_RESUME when an interrupted download can't be resumed. * Improvements to some of the error handling code paths -- ensuring we don't clear the cache for external downloads, ensuring we don't fail with CANNOT_RESUME when the download hasn't actually started yet, removing the restriction on acceptable mime types for public API downloads.

* Add test for many interruptions to a single download.Steve Howard2010-07-271-80/+46
| | | | | | | | | | | | | | | Adding a new test case for downloads that undergo many interruptions (as may happen with a very large download that takes many hours). Includes some refactoring in the test suite. Early on, this test exposed a race condition in which the download manager got some I/O exception while reading from the MockWebServer. I went in and improved/refactored much of the error logging code in DownloadThread to try and track this down. Unfortunately, once I finished, the race condition no longer seems to be reproducible, even with hundreds of runs of the test case. So I've given up on it for now. In any event, error logging is better and much duplicate code has been eliminated.
* Improved support for 302/307 redirects.Steve Howard2010-07-271-61/+90
| | | | | | | | | | | | | | | | | Change the download manager's handling of 302/307 temporary redirects so that after an interruption of any kind, the delayed retry/resume will return to the original URI. This complies better with the HTTP spec. This change also makes the download manager handle other redirects immediately rather than using the delay that's otherwise applied to download errors. I made one more method extraction in DownloadThread to simplify this change, pulling the top-level logic for a single request into executeDownload(). It was then just a matter of introducing a new RetryDownload exeception, similar to StopRequest, and making the redirection code use it. Change-Id: Ic719c5725a9fd2e5eebe4dc03453ee71d9f27cd4
* Fix bug with closing output stream for external downloads.Steve Howard2010-07-271-0/+1
| | | | | | | | I added a unit test to cover this, and it caught another issue with disallowing external destinations outside of the default downloads directory (which are now allowed with the new API). Change-Id: I4df6442bebb06458ad28c85f6bc8cbcbf3ce67a1
* Major refactoring of DownloadThread.run().Steve Howard2010-07-201-604/+727
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Change-Id: If7862349296ad79ff6cdc97e554ad14c01ce1f49
* Support for max download size that may go over mobileSteve Howard2010-07-191-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change introduces support for a maximum download size that may go over a mobile connection. Downloads above this limit will wait for a wifi connection. To accomplish this, I moved a lot of the logic for checking connectivity info into DownloadInfo itself. I then moved the code to call these checks from DownloadService, where it would call the checks before spawning a DownloadThread, into DownloadThread itself. This makes it simpler to check connectivity after we get Content-Length info. It also eliminates the risk of a race condition where connectivity changes between the check and the actual request execution. I realize this change reduces efficiency, because we now call into ConnectivityManager/TelephonyManager twice per DownloadThread, rather than once per DownloadService "tick". I feel that it's OK since its a small amount of computation running relatively infrequently. If we feel that it's a serious concern, and that the efficiency issues outweigh the race problem, I can go easily back to the old approach. I've left out the code to actually fetch the limit. I think this will come from system settings, but I want to double-check, so I'll put it in a separate change. Other changes: * simplify SystemFacade's interface to get connectivity info - rather than returning all connected types, just return the active type, since that should be all we care about * adding @LargeTest to PublicApiFunctionalTest Change-Id: Id1faa2c45bf2dade9fe779440721a1d42cbdfcd1
* Introduce a seam to ConnectivityManager and TelephonyManagerSteve Howard2010-07-151-7/+7
| | | | | | | | | 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. Change-Id: Id6c6b861e1d4ca45b3c1572bfb8ae0aa26af756b
* Support for custom HTTP headers on download requestsSteve Howard2010-07-151-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Stub out the system clock in the download manager, add testsSteve Howard2010-07-011-7/+9
| | | | | | | | | | | | | | Introduce SystemFacade, an interface that allows us to stub out the system clock for testing the download manager. This allows us to test retrying a failed download without having the test wait 60 seconds. This interface can include other dependencies in the future as well. I've also used this to add tests for 503 (retry-after) and 301 (redirect), and I've added a test for download to the cache partition. Other changes: * made MockWebServer capable of checking + rethrowing exceptions from child threads * refactoring + cleanup of DownloadManagerFunctionalTest
