As a first step, this moves PYTHON_UNIT_TESTS to moz.build as a passthru
variable. In the future, we could hook it up to |mach test|.
The __init__.py files may not need to be in the list, but I don't want to
change the list here.
Make the test paths relative to topsrcdir before passing them to
TestResolver. Also do not passing cwd to TestResolver since it will
filter out tests that do not live under the directory where the mach
command is executed.
Verification steps:
Execute a mach test command from any subdirectory. For example:
$ cd testing/tps/
$ ../../mach xpcshell-test ../../services/fxaccounts/tests/xpcshell/
$ ../../mach test ../../services/fxaccounts/tests/xpcshell/
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.
The -*- file variable lines -*- establish per-file settings that Emacs will
pick up. This patch makes the following changes to those lines (and touches
nothing else):
- Never set the buffer's mode.
Years ago, Emacs did not have a good JavaScript mode, so it made sense
to use Java or C++ mode in .js files. However, Emacs has had js-mode for
years now; it's perfectly serviceable, and is available and enabled by
default in all major Emacs packagings.
Selecting a mode in the -*- file variable line -*- is almost always the
wrong thing to do anyway. It overrides Emacs's default choice, which is
(now) reasonable; and even worse, it overrides settings the user might
have made in their '.emacs' file for that file extension. It's only
useful when there's something specific about that particular file that
makes a particular mode appropriate.
- Correctly propagate settings that establish the correct indentation
level for this file: c-basic-offset and js2-basic-offset should be
js-indent-level. Whatever value they're given should be preserved;
different parts of our tree use different indentation styles.
- We don't use tabs in Mozilla JS code. Always set indent-tabs-mode: nil.
Remove tab-width: settings, at least in files that don't contain tab
characters.
- Remove js2-mode settings that belong in the user's .emacs file, like
js2-skip-preprocessor-directives.
A subsequent patch will have another mach command dispatch into
`xpcshell-test`. To avoid redundant resolution of test paths, we now
support passing resolved test objects into the mach command.
