Ævar Arnfjörð Bjarmason	07564773c2	compat: auto-detect if zlib has uncompress2() We have a copy of uncompress2() implementation in compat/ so that we can build with an older version of zlib that lack the function, and the build procedure selects if it is used via the NO_UNCOMPRESS2 $(MAKE) variable. This is yet another "annoying" knob the porters need to tweak on platforms that are not common enough to have the default set in the config.mak.uname file. Attempt to instead ask the system header <zlib.h> to decide if we need the compatibility implementation. This is a deviation from the way we have been handling the "compatiblity" features so far, and if it can be done cleanly enough, it could work as a model for features that need compatibility definition we discover in the future. With that goal in mind, avoid expedient but ugly hacks, like shoving the code that is conditionally compiled into an unrelated .c file, which may not work in future cases---instead, take an approach that uses a file that is independently compiled and stands on its own. Compile and link compat/zlib-uncompress2.c file unconditionally, but conditionally hide the implementation behind #if/#endif when zlib version is 1.2.9 or newer, and unconditionally archive the resulting object file in the libgit.a to be picked up by the linker. There are a few things to note in the shape of the code base after this change: - We no longer use NO_UNCOMPRESS2 knob; if the system header <zlib.h> claims a version that is more cent than the library actually is, this would break, but it is easy to add it back when we find such a system. - The object file compat/zlib-uncompress2.o is always compiled and archived in libgit.a, just like a few other compat/ object files already are. - The inclusion of <zlib.h> is done in <git-compat-util.h>; we used to do so from <cache.h> which includes <git-compat-util.h> as the first thing it does, so from the *.c codes, there is no practical change. - Until objects in libgit.a that is already used gains a reference to the function, the reftable code will be the only one that wants it, so libgit.a on the linker command line needs to appear once more at the end to satisify the mutual dependency. - Beat found a trick used by OpenSSL to avoid making the conditionally-compiled object truly empty (apparently because they had to deal with compilers that do not want to see an effectively empty input file). Our compat/zlib-uncompress2.c file borrows the same trick for portabilty.

Ævar Arnfjörð Bjarmason	25715419bf	CI: don't run "make test" twice in one job The "linux-clang" and "linux-gcc" jobs both run "make test" twice, but with different environment variables. Running these in sequence seems to have been done to work around some constraint on Travis, see `ae59a4e44f` (travis: run tests with GIT_TEST_SPLIT_INDEX, 2018-01-07). By having these run in parallel we'll get jobs that finish much sooner than they otherwise would have. We can also simplify the control flow in "ci/run-build-and-tests.sh" as a result, since we won't run "make test" twice we don't need to run "make" twice at all, let's default to "make all test" after setting the variables, and then override it to just "all" for the compile-only tests. Add a comment to clarify that new "test" targets should adjust $MAKE_TARGETS rather than being added after the "case/esac". This should avoid future confusion where e.g. the compilation-only "pedantic" target will unexpectedly start running tests.

Ævar Arnfjörð Bjarmason	707d2f2fe8	CI: use "$runs_on_pool", not "$jobname" to select packages & config Change the setup hooks for the CI to use "$runs_on_pool" for the "$regular" job. Now we won't need as much boilerplate when adding new jobs to the "regular" matrix, see `956d2e4639` (tests: add a test mode for SANITIZE=leak, run it in CI, 2021-09-23) for the last such commit. I.e. now instead of needing to enumerate each jobname when we select packages we can install things depending on the pool we're running in. That we didn't do this dates back to the now gone dependency on Travis CI, but even if we add a new CI target in the future this'll be easier to port over, since we can probably treat "ubuntu-latest" as a stand-in for some recent Linux that can run "apt" commands.

Ævar Arnfjörð Bjarmason	4a6e4b9602	CI: remove Travis CI support Remove support for running the CI in travis. The last builds in it are from 5 months ago[1] (as of 2021-11-19), and our documentation has referred to GitHub CI instead since `f003a91f5c` (SubmittingPatches: replace discussion of Travis with GitHub Actions, 2021-07-22). We'll now run the "t9810 t9816" and tests on OSX. We didn't before, as we'd carried the Travis exclusion of them forward from `522354d70f` (Add Travis CI support, 2015-11-27). Let's hope whatever issue there was with them was either Travis specific, or fixed since then (I'm not sure). The "apt-add-repository" invocation (which we were doing in GitHub CI) isn't needed, it was another Travis-only case that was carried forward into more general code. See `0f0c51181d` (travis-ci: install packages in 'ci/install-dependencies.sh', 2018-11-01). Remove the "linux-gcc-4.8" job added in `fb9d7431cf` (travis-ci: build with GCC 4.8 as well, 2019-07-18), it only ran in Travis CI. 1. https://travis-ci.org/github/git/git/builds Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	3 years ago
Johannes Schindelin	0e7696c64d	ci: disallow directional formatting As described in https://trojansource.codes/trojan-source.pdf, it is possible to abuse directional formatting (a feature of Unicode) to deceive human readers into interpreting code differently from compilers. For example, an "if ()" expression could be enclosed in a comment, but rendered as if it was outside of that comment. In effect, this could fool a reviewer into misinterpreting the code flow as benign when it is not. It is highly unlikely that Git's source code wants to contain such directional formatting in the first place, so let's just disallow it.

Ævar Arnfjörð Bjarmason	956d2e4639	tests: add a test mode for SANITIZE=leak, run it in CI While git can be compiled with SANITIZE=leak, we have not run regression tests under that mode. Memory leaks have only been fixed as one-offs without structured regression testing. This change adds CI testing for it. We'll now build and small set of whitelisted t00.sh tests under Linux with a new job called "linux-leaks". The CI target uses a new GIT_TEST_PASSING_SANITIZE_LEAK=true test mode. When running in that mode, we'll assert that we were compiled with SANITIZE=leak. We'll then skip all tests, except those that we've opted-in by setting "TEST_PASSES_SANITIZE_LEAK=true". A test setting "TEST_PASSES_SANITIZE_LEAK=true" setting can in turn make use of the "SANITIZE_LEAK" prerequisite, should they wish to selectively skip tests even under "GIT_TEST_PASSING_SANITIZE_LEAK=true". In the preceding commit we started doing this in "t0004-unwritable.sh" under SANITIZE=leak, now it'll combine nicely with "GIT_TEST_PASSING_SANITIZE_LEAK=true". This is how tests that don't set "TEST_PASSES_SANITIZE_LEAK=true" will be skipped under GIT_TEST_PASSING_SANITIZE_LEAK=true: $ GIT_TEST_PASSING_SANITIZE_LEAK=true ./t0001-init.sh 1..0 # SKIP skip all tests in t0001 under SANITIZE=leak, TEST_PASSES_SANITIZE_LEAK not set The intent is to add more TEST_PASSES_SANITIZE_LEAK=true annotations as follow-up change, but let's start small to begin with. In ci/run-build-and-tests.sh we make use of the default "" case to run "make test" without any GIT_TEST_* modes. SANITIZE=leak is known to fail in combination with GIT_TEST_SPLIT_INDEX=true in t0016-oidmap.sh, and we're likely to have other such failures in various GIT_TEST_* modes. Let's focus on getting the base tests passing, we can expand coverage to GIT_TEST_* modes later. It would also be possible to implement a more lightweight version of this by only relying on setting "LSAN_OPTIONS". See <YS9OT/pn5rRK9cGB@coredump.intra.peff.net>[1] and <YS9ZIDpANfsh7N+S@coredump.intra.peff.net>[2] for a discussion of that. I've opted for this approach of adding a GIT_TEST_* mode instead because it's consistent with how we handle other special test modes. Being able to add a "!SANITIZE_LEAK" prerequisite and calling "test_done" early if it isn't satisfied also means that we can more incrementally add regression tests without being forced to fix widespread and hard-to-fix leaks at the same time. We have tests that do simple checking of some tool we're interested in, but later on in the script might be stressing trace2, or common sources of leaks like "git log" in combination with the tool (e.g. the commit-graph tests). To be clear having a prerequisite could also be accomplished by using "LSAN_OPTIONS" directly. On the topic of "LSAN_OPTIONS": It would be nice to have a mode to aggregate all failures in our various scripts, see [2] for a start at doing that which sets "log_path" in "LSAN_OPTIONS". I've punted on that for now, it can be added later. As of writing this we've got major regressions between master..seen, i.e. the t000*.sh tests and more fixed since `31f9acf9ce` (Merge branch 'ah/plugleaks', 2021-08-04) have regressed recently. See the discussion at <87czsv2idy.fsf@evledraar.gmail.com>[3] about the lack of this sort of test mode, and `0e5bba53af` (add UNLEAK annotation for reducing leak false positives, 2017-09-08) for the initial addition of SANITIZE=leak. See also `09595ab381` (Merge branch 'jk/leak-checkers', 2017-09-19), `7782066f67` (Merge branch 'jk/apache-lsan', 2019-05-19) and the recent `936e58851a` (Merge branch 'ah/plugleaks', 2021-05-07) for some of the past history of "one-off" SANITIZE=leak (and more) fixes. As noted in [5] we can't support this on OSX yet until Clang 14 is released, at that point we'll probably want to resurrect that "osx-leaks" job. 1. https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer 2. https://lore.kernel.org/git/YS9OT%2Fpn5rRK9cGB@coredump.intra.peff.net/ 3. https://lore.kernel.org/git/87czsv2idy.fsf@evledraar.gmail.com/ 4. https://lore.kernel.org/git/YS9ZIDpANfsh7N+S@coredump.intra.peff.net/ 5. https://lore.kernel.org/git/20210916035603.76369-1-carenas@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Carlo Marcelo Arenas Belón <carenas@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	3 years ago

Đoàn Trần Công Danh	482c962de4	t: use user-specified utf-8 locale for testing svn In some test-cases, UTF-8 locale is required. To find such locale, we're using the first available UTF-8 locale that returned by "locale -a". However, the locale(1) utility is unavailable on some systems, e.g. Linux with musl libc. However, without "locale -a", we can't guess provided UTF-8 locale. Add a Makefile knob GIT_TEST_UTF8_LOCALE and activate it for linux-musl in our CI system. Rename t/lib-git-svn.sh:prepare_a_utf8_locale to prepare_utf8_locale, since we no longer prepare the variable named "a_utf8_locale", but set up a fallback value for GIT_TEST_UTF8_LOCALE instead. The fallback will be LC_ALL, LANG environment variable, or the first UTF-8 locale from output of "locale -a", in that order.

Matheus Tavares	87094fc2da	ci: run test round with parallel-checkout enabled We already have tests for the basic parallel-checkout operations. But this code can also run be executed by other commands, such as git-read-tree and git-sparse-checkout, which are currently not tested with multiple workers. To promote a wider test coverage without duplicating tests: 1. Add the GIT_TEST_CHECKOUT_WORKERS environment variable, to optionally force parallel-checkout execution during the whole test suite. 2. Set this variable (with a value of 2) in the second test round of our linux-gcc CI job. This round runs `make test` again with some optional GIT_TEST_* variables enabled, so there is no additional overhead in exercising the parallel-checkout code here. Note that tests checking out less than two parallel-eligible entries will fall back to the sequential mode. Nevertheless, it's still a good exercise for the parallel-checkout framework as the fallback codepath also writes the queued entries using the parallel-checkout functions (only without spawning any worker).

We cannot just remove the job because the CI is implicitly depending on the "poison" job being a sort of "default" job in the sense that it's the job that was otherwise run with the default compiler, no other GIT_TEST_* options etc. So let's keep it under the name "linux-gcc-default". This means we can remove the initial "make test" from the "linux-gcc" job (it does another one after setting a bunch of GIT_TEST_* variables). I'm not doing that because it would conflict with the in-flight `334afbc76f` (tests: mark tests relying on the current default for `init.defaultBranch`, 2020-11-18) (currently on the "seen" branch, so the SHA-1 will almost definitely change).

Johannes Schindelin	334afbc76f	tests: mark tests relying on the current default for `init.defaultBranch` In addition to the manual adjustment to let the `linux-gcc` CI job run the test suite with `master` and then with `main`, this patch makes sure that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts that currently rely on the initial branch name being `master by default. To determine which test scripts to mark up, the first step was to force-set the default branch name to `master` in - all test scripts that contain the keyword `master`, - t4211, which expects `t/t4211/history.export` with a hard-coded ref to initialize the default branch, - t5560 because it sources `t/t556x_common` which uses `master`, - t8002 and t8012 because both source `t/annotate-tests.sh` which also uses `master`) This trick was performed by this command: $ sed -i '/^ \. \.\/$test-lib\\|lib-\(bash\\|cvs\\|git-svn$\\|gitweb-lib\)\.sh$/i\ GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\ export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\ ' $(git grep -l master t/t[0-9].sh) \ t/t4211.sh t/t5560.sh t/t8002.sh t/t8012.sh After that, careful, manual inspection revealed that some of the test scripts containing the needle `master` do not actually rely on a specific default branch name: either they mention `master` only in a comment, or they initialize that branch specificially, or they do not actually refer to the current default branch. Therefore, the aforementioned modification was undone in those test scripts thusly: $ git checkout HEAD -- \ t/t0027-auto-crlf.sh t/t0060-path-utils.sh \ t/t1011-read-tree-sparse-checkout.sh \ t/t1305-config-include.sh t/t1309-early-config.sh \ t/t1402-check-ref-format.sh t/t1450-fsck.sh \ t/t2024-checkout-dwim.sh \ t/t2106-update-index-assume-unchanged.sh \ t/t3040-subprojects-basic.sh t/t3301-notes.sh \ t/t3308-notes-merge.sh t/t3423-rebase-reword.sh \ t/t3436-rebase-more-options.sh \ t/t4015-diff-whitespace.sh t/t4257-am-interactive.sh \ t/t5323-pack-redundant.sh t/t5401-update-hooks.sh \ t/t5511-refspec.sh t/t5526-fetch-submodules.sh \ t/t5529-push-errors.sh t/t5530-upload-pack-error.sh \ t/t5548-push-porcelain.sh \ t/t5552-skipping-fetch-negotiator.sh \ t/t5572-pull-submodule.sh t/t5608-clone-2gb.sh \ t/t5614-clone-submodules-shallow.sh \ t/t7508-status.sh t/t7606-merge-custom.sh \ t/t9302-fast-import-unpack-limit.sh We excluded one set of test scripts in these commands, though: the range of `git p4` tests.

Johannes Schindelin	4463ce75b7	ci: do not skip tagged revisions in GitHub workflows When `master` is tagged, and then both `master` and the tag are pushed, Travis CI will happily build both. That is a waste of energy, which is why we skip the build for `master` in that case. Our GitHub workflow is also triggered by tags. However, the run would fail because the `windows-test` jobs are _not_ skipped on tags, but the `windows-build` job _is skipped (and therefore fails to upload the build artifacts needed by the test jobs). In addition, we just added logic to our GitHub workflow that will skip runs altogether if there is already a successful run for the same commit or at least for the same tree.

Johannes Schindelin	ef60e9f74b	ci: stop linking built-ins to the dashed versions Since `e4597aae65` (run test suite without dashed git-commands in PATH, 2009-12-02), we stopped running our tests with `git-foo` binaries found at the top-level directory of a freshly built source tree; instead we have placed only `git` and selected `git-foo` commands that must be on `$PATH` in `bin-wrappers/` and prepended that `bin-wrappers/` to the `PATH` used in the test suite. We did that to catch the tests and scripted Git commands that still try to use the dashed form. Since CI jobs will not install the built Git to anywhere, and the hardlinks we make at the top-level of the source tree for `git-add` and friends are not even used during tests, they are pure waste of resources these days. Thanks to the newly invented `SKIP_DASHED_BUILT_INS` knob, we can now skip creating these links in the source tree. So let's do that. Note that this change introduces a subtle change of behavior: when Git's `cmd_main()` calls `setup_path()`, it inserts the value of `GIT_EXEC_PATH` (defaulting to `<prefix>/libexec/git-core`) at the beginning of the environment variable `PATH`. This is necessary to find e.g. scripted commands that are installed in that location. For the purposes of Git's test suite, the `bin-wrappers/` scripts override `GIT_EXEC_PATH` to point to the top-level directory of the source code. In other words, if a scripted command had used a dashed invocation of a built-in Git command, it would not have been caught previously, which is fixed by this change.

Unfortunately, it's easy to do so, so to help, let's add code to run one of our CI jobs with SHA-256 as the default hash. This will help us detect any problems that may occur. We pick the linux-clang job because it's relatively fast and the linux-gcc job already runs the testsuite twice. We want our tests to run as fast as possible, so we wouldn't want to add a third run to the linux-gcc job. To make sure we properly exercise the code, let's run the tests in the default mode (SHA-1) first and then run a second time with SHA-256.

SZEDER Gábor	60e47f6773	ci: use absolute PYTHON_PATH in the Linux jobs In our test suite, when 'git p4' invokes a Git command as a subprocesses, then it should run the 'git' binary we are testing. Unfortunately, this is not the case in the 'linux-clang' and 'linux-gcc' jobs on Travis CI, where 'git p4' runs the system '/usr/bin/git' instead. Travis CI's default Linux image includes 'pyenv', and all Python invocations that involve PATH lookup go through 'pyenv', e.g. our 'PYTHON_PATH=$(which python3)' sets '/opt/pyenv/shims/python3' as PYTHON_PATH, which in turn will invoke '/usr/bin/python3'. Alas, the 'pyenv' version included in this image is buggy, and prepends the directory containing the Python binary to PATH even if that is a system directory already in PATH near the end. Consequently, 'git p4' in those jobs ends up with its PATH starting with '/usr/bin', and then runs '/usr/bin/git'. So use the absolute paths '/usr/bin/python{2,3}' explicitly when setting PYTHON_PATH in those Linux jobs to avoid the PATH lookup and thus the bogus 'pyenv' from interfering with our 'git p4' tests. Don't bother with special-casing Travis CI: while this issue doesn't affect the corresponding Linux jobs on GitHub Actions, both CI systems use Ubuntu LTS-based images, so we can safely rely on these Python paths.

Đoàn Trần Công Danh	71800d31b5	ci/config: correct instruction for CI preferences From `e76eec3554` (ci: allow per-branch config for GitHub Actions, 2020-05-07), we started to allow contributors decide which branch they want to build with GitHub Actions by checking for a file named "ci/config/allow-ref". In order to assist those contributors, we provided a sample in "ci/config/allow-refs.sample", and instructed them to drop the ".sample", then commit that file to their repository. We've misspelt the filename in that change. Let's fix the spelling. While we're at it, also instruct our contributors introduce that new file to Git before commit, in case of they've never told Git before.

Jeff King	e76eec3554	ci: allow per-branch config for GitHub Actions Depending on the workflows of individual developers, it can either be convenient or annoying that our GitHub Actions CI jobs are run on every branch. As an example of annoying: if you carry many half-finished work-in-progress branches and rebase them frequently against master, you'd get tons of failure reports that aren't interesting (not to mention the wasted CPU). This commit adds a new job which checks a special branch within the repository for CI config, and then runs a shell script it finds there to decide whether to skip the rest of the tests. The default will continue to run tests for all refs if that branch or script is missing. There have been a few alternatives discussed: One option is to carry information in the commit itself about whether it should be tested, either in the tree itself (changing the workflow YAML file) or in the commit message (a "[skip ci]" flag or similar). But these are frustrating and error-prone to use: - you have to manually apply them to each branch that you want to mark - it's easy for them to leak into other workflows, like emailing patches We could likewise try to get some information from the branch name. But that leads to debates about whether the default should be "off" or "on", and overriding still ends up somewhat awkward. If we default to "on", you have to remember to name your branches appropriately to skip CI. And if "off", you end up having to contort your branch names or duplicate your pushes with an extra refspec. By comparison, this commit's solution lets you specify your config once and forget about it, and all of the data is off in its own ref, where it can be changed by individual forks without touching the main tree. There were a few design decisions that came out of on-list discussion. I'll summarize here: - we could use GitHub's API to retrieve the config ref, rather than a real checkout (and then just operate on it via some javascript). We still have to spin up a VM and contact GitHub over the network from it either way, so it ends up not being much faster. I opted to go with shell to keep things similar to our other tools (and really could implement allow-refs in any language you want). This also makes it easy to test your script locally, and to modify it within the context of a normal git.git tree. - we could keep the well-known refname out of refs/heads/ to avoid cluttering the branch namespace. But that makes it awkward to manipulate. By contrast, you can just "git checkout ci-config" to make changes. - we could assume the ci-config ref has nothing in it except config (i.e., a branch unrelated to the rest of git.git). But dealing with orphan branches is awkward. Instead, we'll do our best to efficiently check out only the ci/config directory using a shallow partial clone, which allows your ci-config branch to be just a normal branch, with your config changes on top. - we could provide a simpler interface, like a static list of ref patterns. But we can't get out of spinning up a whole VM anyway, so we might as well use that feature to make the config as flexible as possible. If we add more config, we should be able to reuse our partial-clone to set more outputs. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	5 years ago
Johannes Schindelin	f72f328bc5	ci: let GitHub Actions upload failed tests' directories Arguably, CI builds' most important task is to not only identify regressions, but to make it as easy as possible to investigate what went wrong. In that light, we will want to provide users with a way to inspect the tests' output as well as the corresponding directories.

SZEDER Gábor	d2fae19e0f	ci: make MAKEFLAGS available inside the Docker container in the Linux32 job Once upon a time we ran 'make --jobs=2 ...' to build Git, its documentation, or to apply Coccinelle semantic patches. Then commit `eaa62291ff` (ci: inherit --jobs via MAKEFLAGS in run-build-and-tests, 2019-01-27) came along, and started using the MAKEFLAGS environment variable to centralize setting the number of parallel jobs in 'ci/libs.sh'. Alas, it forgot to update 'ci/run-linux32-docker.sh' to make MAKEFLAGS available inside the Docker container running the 32 bit Linux job, and, consequently, since then that job builds Git sequentially, and it ignores any Makefile knobs that we might set in MAKEFLAGS (though we don't set any for the 32 bit Linux job at the moment). So update the 'docker run' invocation in 'ci/run-linux32-docker.sh' to make MAKEFLAGS available inside the Docker container as well.

SZEDER Gábor	176441bfb5	ci: build Git with GCC 9 in the 'osx-gcc' build job 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.

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'.

Johannes Schindelin	0eb3671ed9	ci(osx): use new location of the `perforce` cask 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.
