* build: add GIT_CACHE_PATH
The merge at https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/1105473 was to specify git cache entirely from the environment variable [and] removal of the general --cache-dir option from gclient
* docs: document GIT_CACHE_PATH in GN build
* fix: try to fix appveyor-gn env syntax
* build: add config to build Electron for tests
* build: run nightly linux builds for the 3-0-x branch
* build: gn: update CI config for linux builds
- run GN debug and testing builds for PRs (as FYI)
- do not run tests for GN debug builds
- run GN release builds nightly
* build: gn: run testing builds on CI instead of release on Windows
Should save some time since release builds set 'official_build=true'
which make the builds take much more time.
* build: gn: use testing config to run CI jobs on Mac
Tests should run faster for testing builds.
Devs can still locally override or add settings by adding lines after
the `import` statement in args.gn.
This will help make sure that everyone has a common set of build args,
and will allow us to update everyone's build args in git.
* Bump electronbuilds/electron* versions
The linux-appname branch has been gathering dust for awhile.
Some of the versions in `master` are higher, and some of the
versions in `linux-appname` are higher to add libnotify.
This commit takes the higher of the two numbers in each case.
* Add libnotify to the Dockerfiles
It appears that the arm build failing with a core dump is a false positive. Testing the latest arm build from master on a raspberry pi 2, it does not core dump.
Note that our CI server is not ready for mips64el yet, so the binaries
of libcc are not available yet. Currently it is downloading the binaries
created by me manually, we should redirect to the official mirror before
merging this PR.
