The GitHub runner image installs the x64 build of Git for Windows, so
its bash and everything run from it execute under x64 emulation on
Windows on ARM, where uname -m reports x86_64 and the staged build got
the wrong architecture. uname -s still reports the machine, as
MINGW64_NT-10.0-26200-ARM64, so use that instead. If the image ever
installs a native arm64 Git for Windows, uname -m will be correct and
this can go.
After a full build, dir_build saves a manifest of build/ files to
staging/.build-manifest. On subsequent runs, if all changed files are
ones that build.sh copies into omni.ja unmodified (chrome/, components/,
resource/, and test/ when tests are staged), zip just those files into
the staged omni.ja instead of rebuilding, taking rebuilds from ~15
seconds to ~0.3 seconds on an M1 Mac. Files are prescreened by size and
mtime so that only changed files need to be hashed. Zotero .ftl files
are also updated at their localization/<locale>/ paths, and test files
are also copied to the staged tests/ directory.
Any other change triggers an automatic full rebuild: files transformed
by build.sh (defaults/, chrome.manifest, version, translators/, styles/,
mozilla .ftl files, CSL locales), removed files, changes to build inputs
in app/ (detected via a size/mtime fingerprint, with xulrunner runtimes
covered by the hash-* files written by fetch_xulrunner), or requesting
tests or devtools that the staged build doesn't include.
Other changes:
- dir_build no longer takes -q and always skips omni.ja compression and
optimization, which only matter for distribution builds made via
build.sh. Use -f (dir_build or build_and_run) to force a full rebuild.
- build_and_run now always rebuilds. -r is deprecated, and -n skips the
rebuild and just launches the app.
- build_and_run no longer passes -purgecaches. Startup caches are
invalidated automatically when the BuildID changes, which now happens
whenever omni.ja is modified (including via add_omni_file), so
relaunching an unchanged build can use the startup cache.
- build_and_run and runtests.sh invoke js-build directly instead of via
'npm run', which saves ~270ms of npm overhead per build.
- The Word integration dylib is now ad-hoc-signed by dir_build, and only
on full rebuilds, since incremental updates don't invalidate the
existing signature. This also covers test builds, which were never
signed before.
- dir_build removes broken symlinks left in build/ when source files are
deleted, which previously broke rsync in prepare_build.
`fetch_xulrunner`, `dir_build`, and `build.sh` now take an optional `-a`
argument on Windows and Linux to specify the architecture to
fetch/build. If `-a` is omitted for `dir_build` (as in `build_and_run`),
it defaults to the current architecture.
xulrunner hashes are now computed for each architecture. This changes
some filenames in xulrunner/, so you may want to clean out some old
folders/files.
This removes the custom handling for CI, since it will now default to
the architecture of the test runner.
