I'm working on fixing up all tests that rely on fs.currentDirectory to allow us to run concurrently. This one proved to be really tricky because it calls a lot of code and spawns multiple processes that have a mix of absolute and relative paths passed to them. I managed to handle some of it with a ChrootFileSystem, but the paths passed to the external processes were wrong.
The functionality here is covered by all of the integration tests that use flutter_tester that were added after this, including flutter_run_test.dart, lifetime_test.dart etc. in this same folder but because they're run through `flutter run` as a separate process they get to set their own working directories without affecting other tests if run concurrently.
* Add a detach command to detach without terminating (#21376)
* Add a detach command to detach without terminating
Fixes#21154.
* Bump protocol version for app.detach
* Tweak to detach/quit text
* Change logPrefix to named param
* Fix the text that the devicelab attach test looks for
* Rename test file
* Fix detection to work regardless of whether there are other devices
On Windows we get one message, but on Mac we get another (because of the Simulator always being available).
* Allow FlutterTester to be provided with the working directory for execution
Previously this test set fs.currentDirectory which prevents running tests concurrently. This allows setting the working directory for a FlutterTester in the cosntructor (optionally) and passes it through from the test (without setting fs.currentDirectory).
* Remove trailing whitespace
* Add a detach command to detach without terminating
Fixes#21154.
* Bump protocol version for app.detach
* Tweak to detach/quit text
* Change logPrefix to named param
* Update asset_bundle_package_test to use MemoryFileSystem
This updates all tests in this file to use a memory filesystem (same as I did for asset_bundle_package_font_test) based on the current platform.
There were already a few minor tests at the bottom using a MemoryFileSystem and being run for all platforms - however this complicated the shared code I changed above to support Windows natively so I changed them to also work the same as others (that is, they just run the native platforms so require running on all to get full coverage - though this is the case for almost all other tests anyway).
* Move fixPath to the correct place
* First step in Flutter Doctor refactor. Assigns categories to all validators.
* Revert "Roll engine e54bc4ea1832..a84b210b3d26 (6 commits) (#20453)"
This reverts commit 05c2880a17.
* Split iOS and Android workflows into workflow and validator classes.
* Change ValidatorCategory to handle standalone validators that share a
category (e.g. IntelliJ).
Also make Android Studio and Android toolchain use separate categories.
At this stage, flutter doctor output matches what it was previously.
(The summary() method itself has not yet been changed )
* Change doctor summary code to support validator categories.
Output is still unchanged.
* Handle small formatting issues.
* Flip Flutter category's isGroup field to false until it's actually
needed.
* Revert auto-generated formatting changes to keep those lines from
muddying the pull.
* Small fixes pointed out by analyzer.
* Properly fix analyzer issues around const constructors.
* Small changes to address comments.
* Add tests to verify grouped validator behavior and validationtype
merging.
* Update doctor.dart
* Add comments for clarification.
* Change assert_bundle_package_font_test to memory file system
This is to work towards being able to run the tests without `-j1` (#21113). These tests were using the real filesystem and setting/relying on fs.currentDirectory. There was a comment about this being because the memory provider didnt' support POSIX and Windows, however that seems to have changed since (and many other asset tests already do something similar to this).
* Trim trailing whitespace
* Add a workaround for Windows path slash directions
Strictly this is correct, but the real FS can tolerate either path. The in-memory file system is more strict (see https://github.com/google/file.dart/issues/112).
* Extract a helper for writing schema files in tests
* Missed file when saving!
* Remove redundant comment
* Rename writeBasicSchema -> writeEmptySchema
* Use the file we already have to write contents
* Make comments more descriptive
* Remove another dupe of writeSchema to use the shared one
* Rename schema -> pubspec_schema
* Trim whitespace
This patch eliminates the --preview-dart-2/--no-preview-dart-2 flag,
hardcoding all uses to true. It also defaults all previewDart2 method
parameters to true, where they hadn't yet been.
A series of subsequent patches will eliminate all previewDart2
parameters and the associated code from within the codebase.
* Unskip integration tests on Windows that now pass
The referenced issue is closed and these tests pass for me locally on Windows now.
* Remove import that's no longer used
* Add another issue that is afffecting these tests on Windows
* Add a hot restart test and mark skip on Windows
Skipped due to https://github.com/flutter/flutter/issues/21348.
DevFS.update only runs in Dart 2 mode when the generator parameter is
supplied. In Dart 2 mode, both mainPath and pathToReload are required
parameters; this patch marks them as such.
generator is required for running in Dart 2. All call sites other than tests already explicitly set this value.
Note the statements on line 510 and line 516 for why mainPath and pathToReload are required.
Its type uses a generic type which is limited to library-visibility.
Eliminating compilationQueue from ResidentCompiler's public interface
makes it possible to mock in tests.
When switching between channels, we were leaving around the version freshness stamp file (bin/cache/flutter_version_check.stamp), which meant that the flutter tool would read from that file to see what the cached date of the most recent commit to the current channel (branch) was. The problem was that since the file was created while on the previous channel, the cached date was for the wrong channel, so if you switch from master to beta, flutter would think that the channel was out of date, and a new version was available, at least for three days after the first time it checked (after three days since the last time the freshness was checked, the cached date would get updated).
This PR modifies the channel command to remove that stamp file whenever the user switches channels, so that the cached date will be from the right channel when it is recreated.
Fixes#21134
This is a bit of a stab in the dark for a flake sometimes seen on bots (but I can't repro locally) #20822. Detaching from a Flutter app currently seems to terminate it, so it may be the cause of the "app not found" when trying to stop the app subsequently.
This change means we stop the app from the main process first, before terminating the attach process.
* Fix coverage collection crash
Based on Jason's patch in https://github.com/flutter/flutter/pull/19546/
This is more or less the same but I tried to avoid using `dynamic`.
* Improve argument and variable names in flutter_platform
* Don't bother with reduce, since the order is guaranteed.
* Don't time out if process terminates when told to stop but response was not processed
While trying to reproduce #20822 I found a condition where the app may quit before the `app.stop` response is received but this code (which is called in integration test teardown) would sit around waiting and time out. With this change, the process exit is considered a valid response to the stop request.
* Add process exit to log for better errors in failures
This log can be turned on for debugging but is also dumped when a test fails (in certain conditions). With this in the log, it'll be clear if the timeout is because we're waiting for an event but the process quit.
* Start logger in startProgress to avoid assertion failure
There are lots of places that create a Status() and all but two of them call ..start() immediately. This is one of the places that doesn't, which causes an assertion failure when running with --enable-asserts and the other is in the same file (I suspect it's also incorrect, but possibly it's never used - I'll look at that separately when I can trace some code that calls it).
Fixes#20812.
* Enable asserts for tools tests
* Fix lint
* Rename enableAsserts -> enableFlutterToolAsserts
To make it clearer that it only enables asserts for flutter_tools when set.
This test is sometimes flaky (#20822) because the two processes try to stop the same app. This fix changes to just gracefully terminate the attach process without explicitly trying to stop and then uses the original spawning process to stop the app.
I can't repro the flake locally to be certain, but I've verified only one stop command is sent now so it *should* be good.
