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.

8a06d56ccb ci: run tests with SHA-256
Now that we have Git supporting SHA-256, we'd like to make sure that we
don't regress that state.  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.  We explicitly specify SHA-1 for the first run so that if
we change the default in the future, we make sure to test both cases.

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.

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.

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.

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.

This commit adds build steps that are only executed when tests failed,
uploading the relevant information as build artifacts. These artifacts
can then be downloaded by interested parties to diagnose the failures
more efficiently.

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.  Set
CC=gcc for the 32 bit Linux job, because that's the compiler installed
in the 32 bit Linux Docker image that we use (Travis CI nowadays sets
CC=clang by default, but clang is not installed in this image).

Python2 reached end of life, and we have been preparing our Python
scripts to work with Python3.  'git p4', the main in-tree user of
Python, has just received a number of compatibility updates.  Our
other notable Python script 'contrib/svn-fe/svnrdump_sim.py' is only
used in 't9020-remote-svn.sh', and is apparently already compatible
with both Python2 and 3.

Our CI jobs currently only use Python2.  We want to make sure that
these Python scripts do indeed work with Python3, and we also want to
make sure that these scripts keep working with Python2 as well, for
the sake of some older LTS/Enterprise setups.

Therefore, pick two jobs and use Python3 there, while leaving other
jobs to still stick to Python2 for now.

This job runs the test suite twice, once in regular mode, and once with
a whole slew of `GIT_TEST_*` variables set.

Now that the built-in version of `git add --interactive` is
feature-complete, let's also throw `GIT_TEST_ADD_I_USE_BUILTIN` into
that fray.

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.

a85efb5985 t5608-clone-2gb.sh: turn GIT_TEST_CLONE_2GB into a bool
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.

0dbc4a0edf ci(osx): update homebrew-cask repository with less noise
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.

7d4733c501 ci: fix GCC install in the Travis CI GCC OSX job
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.

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.

c46ebc2496 travis-ci: do not skip successfully tested trees in debug mode
Travis CI offers shell access to its virtual machine environment
running the build jobs, called "debug mode" [1].  After restarting a
build job in debug mode and logging in, the first thing I usually do
is to install dependencies, i.e. run './ci/install-dependencies.sh'.
This works just fine when I restarted a failed build job in debug
mode.  However, after restarting a successful build job in debug mode
our CI scripts get all clever, and exit without doing anything useful,
claiming that "This commit's tree has already been built and tested
successfully" [2].  Our CI scripts are right, and we do want to skip
building and testing already known good trees in "regular" CI builds.
In debug mode, however, this is a nuisiance, because one has to delete
the cache (or at least the 'good-trees' file in the cache) to proceed.

Let's update our CI scripts, in particular the common 'ci/lib.sh', to
not skip previously successfully built and tested trees in debug mode,
so all those scripts will do what there were supposed to do even when
a successful build job was restarted in debug mode.

f6461b82b9 Documentation: fix build with Asciidoctor 2
Our documentation toolchain has traditionally been built around DocBook
4.5.  This version of DocBook is the last DTD-based version of DocBook.
In 2009, DocBook 5 was introduced using namespaces and its syntax is
expressed in RELAX NG, which is more expressive and allows a wider
variety of syntax forms.

Asciidoctor, one of the alternatives for building our documentation,
moved support for DocBook 4.5 out of core in its recent 2.0 release and
now only supports DocBook 5 in the main release.  The DocBoook 4.5
converter is still available as a separate component, but this is not
available in most distro packages.  This would not be a problem but for
the fact that we use xmlto, which is still stuck in the DocBook 4.5 era.

xmlto performs DTD validation as part of the build process.  This is not
problematic for DocBook 4.5, which has a valid DTD, but it clearly
cannot work for DocBook 5, since no DTD can adequately express its full
syntax.  In addition, even if xmlto did support RELAX NG validation,
that wouldn't be sufficient because it uses the libxml2-based xmllint to
do so, which has known problems with validating interleaves in RELAX NG.

Fortunately, there's an easy way forward: ask Asciidoctor to use its
DocBook 5 backend and tell xmlto to skip validation.  Asciidoctor has
supported DocBook 5 since v0.1.4 in 2013 and xmlto has supported
skipping validation for probably longer than that.

We also need to teach xmlto how to use the namespaced DocBook XSLT
stylesheets instead of the non-namespaced ones it usually uses.
Normally these stylesheets are interchangeable, but the non-namespaced
ones have a bug that causes them not to strip whitespace automatically
from certain elements when namespaces are in use.  This results in
additional whitespace at the beginning of list elements, which is
jarring and unsightly.

We can do this by passing a custom stylesheet with the -x option that
simply imports the namespaced stylesheets via a URL.  Any system with
support for XML catalogs will automatically look this URL up and
reference a local copy instead without us having to know where this
local copy is located.  We know that anyone using xmlto will already
have catalogs set up properly since the DocBook 4.5 DTD used during
validation is also looked up via catalogs.  All major Linux
distributions distribute the necessary stylesheets and have built-in
catalog support, and Homebrew does as well, albeit with a requirement to
set an environment variable to enable catalog support.

On the off chance that someone lacks support for catalogs, it is
possible for xmlto (via xmllint) to download the stylesheets from the
URLs in question, although this will likely perform poorly enough to
attract attention.  People still have the option of using the prebuilt
documentation that we ship, so happily this should not be an impediment.

Finally, we need to filter out some messages from other stylesheets that
occur when invoking dblatex in the CI job.  This tool strips namespaces
much like the unnamespaced DocBook stylesheets and prints similar
messages.  If we permit these messages to be printed to standard error,
our documentation CI job will fail because we check standard error for
unexpected output.  Due to dblatex's reliance on Python 2, we may need
to revisit its use in the future, in which case this problem may go
away, but this can be delayed until a future patch.

The final message we filter is due to libxslt on modern Debian and
Ubuntu.  The patch which they use to implement reproducible ID
generation also prints messages about the ID generation.  While this
doesn't affect our current CI images since they use Ubuntu 16.04 which
lacks this patch, if we upgrade to Ubuntu 18.04 or a modern Debian,
these messages will appear and, like the above messages, cause a CI
failure.

3960290675 ci: restore running httpd tests
Once upon a time GIT_TEST_HTTPD was a tristate variable and we
exported 'GIT_TEST_HTTPD=YesPlease' in our CI scripts to make sure
that we run the httpd tests in the Linux Clang and GCC build jobs, or
error out if they can't be run for any reason [1].

Then 3b072c577b (tests: replace test_tristate with "git env--helper",
2019-06-21) came along, turned GIT_TEST_HTTPD into a bool, but forgot
to update our CI scripts accordingly.  So, since GIT_TEST_HTTPD is set
explicitly, but its value is not one of the standardized true values,
our CI jobs have been simply skipping the httpd tests in the last
couple of weeks.

Set 'GIT_TEST_HTTPD=true' to restore running httpd tests in our CI
jobs.
