ci: build Git with GCC 9 in the 'osx-gcc' build job

2019-11-29T21:18:48Z

Our 'osx-gcc' build job on Travis CI relied on GCC 8 being installed (but not linked) in the image we use [1]. Alas, since the last update of this image a few days ago this is not the case anymore, and now it contains GCC 9 (installed and linked) instead of GCC 8. The results are failed 'osx-gcc' jobs, because they can't find the 'gcc-8' command [2]. Let's move on to use GCC 9, with hopefully better error reporting and improved -Wfoo flags and what not. On Travis CI this has the benefit that we can spare a few seconds while installing dependencies, because it already comes pre-installed, at least for now. The Azure Pipelines OSX image doesn't include GCC, so we have to install it ourselves anyway, and then we might as well install the newer version. In a vain attempt I tried to future-proof this a bit: - Install 'gcc@9' specifically, so we'll still get what we want even after GCC 10 comes out, and the "plain" 'gcc' package starts to refer to 'gcc@10'. - Run both 'brew install gcc@9' and 'brew link gcc@9'. If 'gcc@9' is already installed and linked, then both commands are noop and exit with success. But as we saw in the past, sometimes the image contains the expected GCC package installed but not linked, so maybe it will happen again in the future as well. In that case 'brew install' is still a noop, and instructs the user to run 'brew link' instead, so that's what we'll do. And if 'gcc@9' is not installed, then 'brew install' will install it, and the subsequent 'brew link' becomes a noop. An additional benefit of this patch is that from now on we won't unnecessarily install GCC and its dependencies in the 'osx-clang' jobs on Azure Pipelines.

t5608-clone-2gb.sh: turn GIT_TEST_CLONE_2GB into a bool

2019-11-23T02:16:10Z

The GIT_TEST_CLONE_2GB environment variable is only ever checked with 'test -z' in 't5608-clone-2gb.sh', so any non-empty value is interpreted as "yes, run these expensive tests", even 'GIT_TEST_CLONE_2GB=NoThanks'. Similar GIT_TEST_* environment variables have already been turned into bools in 3b072c577b (tests: replace test_tristate with "git env--helper", 2019-06-21), so let's turn GIT_TEST_CLONE_2GB into a bool as well, to follow suit. Our CI builds set GIT_TEST_CLONE_2GB=YesPlease, so adjust them accordingly, thus removing the last 'YesPlease' from our CI scripts. Signed-off-by: SZEDER Gábor Signed-off-by: Junio C Hamano

ci(osx): update homebrew-cask repository with less noise

2019-11-20T02:55:46Z

The OSX CI build procedure updates the homebrew-cask repository before attempting to install perforce again, after seeing an installation failure. This involves a "git pull" that by default computes and outputs diffstat, which would only grow as the time goes by and the repository cast in stone in the CI build image becomes more and more stale relative to the upstream repository in the outside world. Suppress the diffstat to both save cycles to generate it, and strain on the eyeballs to skip it. Reported-by: SZEDER Gábor Helped-by: Johannes Schindelin Signed-off-by: Junio C Hamano

ci: fix GCC install in the Travis CI GCC OSX job

2019-10-24T02:31:07Z

A few days ago Travis CI updated their existing OSX images, including the Homebrew database in the xcode10.1 OSX image that we use. Since then installing dependencies in the 'osx-gcc' job fails when it tries to link gcc@8: + brew link gcc@8 Error: No such keg: /usr/local/Cellar/gcc@8 GCC8 is still installed but not linked to '/usr/local' in the updated image, as it was before this update, but now we have to link it by running 'brew link gcc'. So let's do that then, and fall back to linking gcc@8 if it doesn't, just to be sure. Our builds on Azure Pipelines are unaffected by this issue. The OSX image over there doesn't contain the gcc@8 package, so we have to 'brew install' it, which already takes care of linking it to '/usr/local'. After that the 'brew link gcc' command added by this patch fails, but the ||-chained fallback 'brew link gcc@8' command succeeds with an "already linked" warning.

ci(osx): use new location of the `perforce` cask

2019-10-23T02:46:41Z

The Azure Pipelines builds are failing for macOS due to a change in the location of the perforce cask. The command outputs the following error: + brew install caskroom/cask/perforce Error: caskroom/cask was moved. Tap homebrew/cask-cask instead. So let's try to call `brew cask install perforce` first (which is what that error message suggests, in a most round-about way). Prior to 672f51cb we used to install the 'perforce' package with 'brew install perforce' (note: no 'cask' in there). The justification for 672f51cb was that the command 'brew install perforce' simply stopped working, after Homebrew folks decided that it's better to move the 'perforce' package to a "cask". Their justification for this move was that 'brew install perforce' "can fail due to a checksum mismatch ...", and casks can be installed without checksum verification. And indeed, both 'brew cask install perforce' and 'brew install caskroom/cask/perforce' printed something along the lines of: ==> No checksum defined for Cask perforce, skipping verification It is unclear why 672f51cb used 'brew install caskroom/cask/perforce' instead of 'brew cask install perforce'. It appears (by running both commands on old Travis CI macOS images) that both commands worked all the same already back then. In any case, as the error message at the top of this commit message shows, 'brew install caskroom/cask/perforce' has stopped working recently, but 'brew cask install perforce' still does, so let's use that. CI servers are typically fresh virtual machines, but not always. To accommodate for that, let's try harder if `brew cask install perforce` fails, by specifically pulling the latest `master` of the `homebrew-cask` repository. This will still fail, of course, when `homebrew-cask` falls behind Perforce's release schedule. But once it is updated, we can now simply re-run the failed jobs and they will pick up that update. As for updating `homebrew-cask`: the beginnings of automating this in https://dev.azure.com/gitgitgadget/git/_build?definitionId=11&_a=summary will be finished once the next Perforce upgrade comes around.
