If we botch things in libxul badly enough that startup cache
precompilation works, but xpcshell self tests fail, it's nice to get
understandable stacks for asserts or crashes inside libxul.
This commit contains a few things:
* Update our copy of google-breakpad to upstream c53ed143108948eb7e2d7ee77dc8c0d92050ce7c
* Get rid of all but one local patch, fold a few related local patches into one
* Misc build fixup to sync with upstream--adding a few new moz.build files,
source files
* The final bits of unhooking Breakpad from the profiler:
** Revert to only building toolkit/crashreporter if MOZ_CRASHREPORTER.
** Stop building bits of Breakpad that we only needed for the profiler.
** Remove a few bits of profiler code that were used to interface with Breakpad.
** Remove toolkit/crashreporter/breakpad-logging, which was only used to
suppress Breakpad logging for the in-process stackwalker.
* Upstream removed their Android-compat sys/ucontext.h because the Android NDK
added it, but the bionic we're using for Gonk builds is too old, so add a
copy of the previous version of those files to
toolkit/crashreporter/gonk-include to keep Gonk building.
* Consolidate moz.build files under toolkit/crashreporter/google-breakpad/client/linux
There's a test for add_task() in selftest.py called ADD_TASK_MULTIPLE, which tests if
multiple add_task() tests are working. The test added in this commit does the exact same
except without run_test(). Since the original tests included this, I thought it would make
a good case for checking if the removal of run_test() is working as expected. Please remove
if this is unnecessary.
Since the simple test cases before this bug had cases for both passing and
failing, it would be a good idea to follow suit and add similar failing tests
for when run_test() is omitted.
Like the other simple tests defined in selftest.py, SIMPLE_FAILING_TEST,
ADD_TEST_FAILING, etc., it follows a similar pattern except these are done
without run_test() defined.
Four new test cases have been added to testing/xpcshell/selftest.py.
These new tests check that tests where run_test() is not defined
work properly.
The test cases check the following cases:
1. when only add_test() is used.
2. when only add_task() is used.
3. when both add_task() and add_test() is used.
4. when a test file is empty, i.e. contains no add_test(), add_task() or
run_test().
Test bodies only consist of do_check_true(true) calls to make up a minimal
test without run_test() in the same vein as the other simple tests defined
previously.
Also, broke a comment up that was too long.
This adds a format option to mach environment and uses it in client.mk to
create a .mozconfig.json in the objdir, containing all the relevant data
from mozconfig. If the mozconfig doesn't change in a way that alters that
data, we still skip configure.
At the same time, use mach environment in place of mozconfig2configure and
mozconfig2client-mk, which makes us now have only one mozconfig reader.
Also, in the mozconfig reader, keep track of environment variables (as
opposed to shell variables), so that changes such as a variable that was
exported not being exported anymore is spotted. At the opposite, in order
for irrelevant environment variable changes not to incur in re-running
configure, only a set of environment variables are stored when they are
unmodified. Otherwise, changes such as using a different terminal window,
or even rebooting, would trigger reconfigures.
Finally, make mach environment emit both MOZ_OBJDIR and OBJDIR for
client.mk, and cleanup some objdir-related things in client.mk..
At the same time, make the mozconfig reader take MOZ_OBJDIR from the
environment if it is defined there and not in the mozconfig.
If an xpcshell test called run_next_test() from inside an add_task(),
bad things would happen. This patch detects that behavior and aborts the
test immediately with an actionable error message.
