For thoroughness when checking for one-shot environment variable
assignments at shell function call sites, check-non-portable-shell
stitches together incomplete lines (those ending with backslash). This
allows it to correctly flag such undesirable usage even when the
variable assignment and function call are split across lines, for
example:
FOO=bar \
func
where 'func' is a shell function.
The stitching is accomplished like this:
while (<>) {
chomp;
# stitch together incomplete lines (those ending with "\")
while (s/\\$//) {
$_ .= readline;
chomp;
}
# detect unportable/undesirable shell constructs
...
}
Although this implementation is well supported in reasonably modern Perl
versions (5.10 and later), it fails with older versions (such as Perl
5.8 shipped with ancient Mac OS 10.5). In particular, in older Perl
versions, 'readline' is not connected to the file handle associated with
the "magic" while (<>) {...} construct, so 'readline' throws a
"readline() on unopened filehandle" error. Work around this problem by
dropping readline() and instead incorporating the stitching of
incomplete lines directly into the existing while (<>) {...} loop.

Enable DEP (Data Execution Prevention) and ASLR (Address Space Layout
Randomization) support. This applies to both 32bit and 64bit builds
and makes it substantially harder to exploit security holes in Git by
offering a much more unpredictable attack surface.
ASLR interferes with GDB's ability to set breakpoints. A similar issue
holds true when compiling with -O2 (in which case single-stepping is
messed up because GDB cannot map the code back to the original source
code properly). Therefore we simply enable ASLR only when an
optimization flag is present in the CFLAGS, using it as an indicator
that the developer does not want to debug in GDB anyway.

In Git for Windows, we use the MSYS2 Bash which inherits a non-standard
PID model from Cygwin's POSIX emulation layer: every MSYS2 process has a
regular Windows PID, and in addition it has an MSYS2 PID (which
corresponds to a shadow process that emulates Unix-style signal
handling).
With the upgrade to the MSYS2 runtime v3.x, this shadow process cannot
be accessed via `OpenProcess()` any longer, and therefore t6500 thought
incorrectly that the process referenced in `gc.pid` (which is not
actually a real `gc` process in this context, but the current shell) no
longer exists.
Let's fix this by making sure that the Windows PID is written into
`gc.pid` in this test script so that `git.exe` is able to understand
that that process does indeed still exist.

The fread/fwrite-like functions in http.c, namely fread_buffer,
fwrite_buffer, fwrite_null, fwrite_sha1_file all return the
multiplication of the size and number of items they are being given.
Practically speaking, it doesn't matter, because in all contexts where
those functions are used, size is 1.
But those functions being similar to fread and fwrite (the curl API is
designed around being able to use fread and fwrite directly), it might
be preferable to make them behave like fread and fwrite, which, from
the fread/fwrite manual page, is:
On success, fread() and fwrite() return the number of items read
or written. This number equals the number of bytes transferred
only when size is 1. If an error occurs, or the end of the file
is reached, the return value is a short item count (or zero).

This one is tricky.
When `core.fsmonitor` is set, a `refresh_index()` will not perform a
full scan of files that might be modified, but will query the fsmonitor
and refresh only the ones that have been actually touched.
Due to implementation details, the fsmonitor is queried in
`refresh_cache_ent()`, but of course it only has to be queried once, so
we set a flag when we did that. But when the index was discarded, we did
not re-set that flag.
So far, this is only covered by our test suite when running with
GIT_TEST_FSMONITOR=$PWD/t7519/fsmonitor-all, and only due to the way the
built-in stash interacts with the recursive merge machinery.
Let's introduce a straight-forward regression test for this.
We simply extend the "read & discard index" loop in `test-tool
read-cache` to optionally refresh the index, report on a given file's
status, and then modify that file. Due to the bug described above, only
the first refresh will actually query the fsmonitor; subsequent loop
iterations will not.

As noted in preceding commits setting GIT_TEST_INSTALLED has never
been supported or documented, and as noted in an earlier t/perf/README
change to the extent that it's been documented nobody's notices that
the example hasn't worked since 3c8f12c96c ("test-lib: reorder and
include GIT-BUILD-OPTIONS a lot earlier", 2012-06-24).
We could directly support GIT_TEST_INSTALLED for invocations without
the "run" script, such as:
GIT_TEST_INSTALLED=../../ ./p0000-perf-lib-sanity.sh
GIT_TEST_INSTALLED=/home/avar/g/git ./p0000-perf-lib-sanity.sh
But while not having this "error" will "work", it won't write the the
resulting "test-results/*" files to the right place, and thus a
subsequent call to aggregate.perl won't work as expected.
Let's just tell the user that they need to use the "run" script,
which'll correctly deal with this and set the right
PERF_RESULTS_PREFIX.
If someone's in desperate need of bypassing "run" for whatever reason
they can trivially do so by setting "PERF_SET_GIT_TEST_INSTALLED", but
not we won't have people who expect GIT_TEST_INSTALLED to just work
wondering why their aggregation doesn't work, even though they're
running the right "git".

Change the output file names in test-results/ to be
"test-results/bindir_<munged dir>" rather than just
"test-results/<munged dir>".
This is for consistency with the "build_" directories we have for
built revisions, i.e. "test-results/build_<SHA-1>".
There's no user-visible functional changes here, it just makes it
easier to see at a glance what "test-results" files are of what "type"
as they're all explicitly grouped together now, and to grep this code
to find both the run_dirs_helper() implementation and its
corresponding aggregate.perl code.
Note that we already guarantee that the rest of the
PERF_RESULTS_PREFIX is an absolute path, and since it'll start with
e.g. "/" which we munge to "_" we'll up with a readable string like
"bindir_home_avar[...]".

Follow-up my preceding change which fixed the immediate "./run
<revisions>" regression in 0baf78e7bc ("perf-lib.sh: rely on
test-lib.sh for --tee handling", 2019-03-15) and entirely get rid of
GIT_TEST_INSTALLED from perf-lib.sh (and aggregate.perl).
As noted in that change the dance we're doing with GIT_TEST_INSTALLED
perf-lib.sh isn't necessary, but there I was doing the most minimal
set of changes to quickly fix a regression.
But it's much simpler to never deal with the "GIT_TEST_INSTALLED" we
were setting in perf-lib.sh at all. Instead the run_dirs_helper() sets
the previously inferred $PERF_RESULTS_PREFIX directly.
Setting this at the callsite that's already best positioned to
exhaustively know about all the different cases we need to handle
where PERF_RESULTS_PREFIX isn't what we want already (the empty
string) makes the most sense. In one-off cases like:
./run ./p0000-perf-lib-sanity.sh
./p0000-perf-lib-sanity.sh
We'll just do the right thing because PERF_RESULTS_PREFIX will be
empty, and test-lib.sh takes care of finding where our git is.
Any refactoring of this code needs to change both the shell code and
the Perl code in aggregate.perl, because when running e.g.:
./run ../../ -- <test>
The "../../" path to a relative bindir needs to be munged to a
filename containing the results, and critically aggregate.perl does
not get passed the path to those aggregations, just "../..".
Let's fix cases where aggregate.perl would print e.g. ".." in its
report output for this, and "git" for "/home/avar/g/git", i.e. it
would always pick the last element. Now'll always print the full path
instead.
This also makes the code sturdier, e.g. you can feed "../.." to
"./run" and then an absolute path to the aggregate.perl script, as
long as the absolute path and "../.." resolved to the same directory
printing the aggregation will work.
Also simplify the "[_*]" on the RHS of "tr -c", we're trimming
everything to "_", so we don't need that.

Fix a really bad regression in 0baf78e7bc ("perf-lib.sh: rely on
test-lib.sh for --tee handling", 2019-03-15). Since that change all
runs of different <revisions> of git have used the git found in the
user's $PATH, e.g. /usr/bin/git instead of the <revision> we just
built and wanted to performance test.
The problem starts with GIT_TEST_INSTALLED not working like our
non-perf tests with the "run" script. I.e. you can't run performance
tests against a given installed git. Instead we expect to use it
ourselves to point GIT_TEST_INSTALLED to the <revision> we just built.
However, we had been relying on '$(cd "$GIT_TEST_INSTALLED" && pwd)'
to resolve that relative $GIT_TEST_INSTALLED to an absolute
path *before* test-lib.sh was loaded, in cases where it was
e.g. "build/<rev>/bin-wrappers" and we wanted "<abs_path>build/...".
This change post-dates another proposed solution by a few days[1], I
didn't notice that version when I initially wrote this. I'm doing the
most minimal thing to solve the regression here, a follow-up change
will move this result prefix selection logic entirely into the "run"
script.
This makes e.g. these cases all work:
./run . $PWD/../../ origin/master origin/next HEAD -- <tests>
As well as just a plain one-off:
./run <tests>
And, since we're passing down the new GIT_PERF_DIR_MYDIR_REL we make
sure the bug relating to aggregate.perl not finding our files as
described in 0baf78e7bc doesn't happen again.
What *doesn't* work is setting GIT_TEST_INSTALLED to a relative path,
this will subtly fail in test-lib.sh. This has always been the case
even before 0baf78e7bc, and as documented in t/README the
GIT_TEST_INSTALLED variable should be set to an absolute path (needs
to be set "to the bindir", which is always absolute), and the "perf"
framework expects to munge it itself.
Perhaps that should be dealt with in the future to allow manually
setting GIT_TEST_INSTALLED, but as a preceding commit showed the user
can just use the "run" script, which'll also pick the right output
directory for the test results as expected by aggregate.perl.

Remove the setting of the "environment" from the --codespeed output. I
don't think this is useful, and it helps with a later refactoring
where we GIT_TEST_INSTALLED stop munging/reading GIT_TEST_INSTALLED in
the perf tests in so many places.
This was added in 05eb1c37ed ("perf/aggregate: implement codespeed
JSON output", 2018-01-05), but since the "run" scripts uses
"GIT_TEST_INSTALLED" internally this was only ever useful for one-off
runs of a single revision as all the "environment" values would be
ones for whatever directory the "run" script ran last.
Let's instead fall back on the "uname -r" case, which is the sort of
thing the environment should be set to, not something that duplicates
other parts of the codpseed output. For setting the "environment" to
something custom the perf.repoName variable can be used. See
19cf57a92e ("perf/run: read GIT_PERF_REPO_NAME from perf.repoName",

Remove those fallbacks by reverting fe3b2b7b82 (Enable support for
IPv6 on MinGW, 2009-11-24) and using the functions directly (without
'ipv6_' prefix).

On Windows, UNC paths are a very convenient way to share data, and
alternates are all about sharing data.
We fixed a bug where alternates specifying UNC paths were not handled
properly, and it is high time that we add a regression test to ensure
that this bug is not reintroduced.

When using cvsnt + msys + git, it seems like the output of cvs status
had \r\n in it, and caused the command to fail.
This fixes that.

Since e7e9f5e7a1 (travis-ci: enable Git SVN tests t91xx on Linux,
2016-05-19) some of our Travis CI build jobs install the 'git-svn'
package, because it was a convenient way to install its dependencies,
which are necessary to run our 'git-svn' tests (we don't actually need
the 'git-svn' package itself). However, from those dependencies,
namely the 'libsvn-perl', 'libyaml-perl', and 'libterm-readkey-perl'
packages, only 'libsvn-perl' is necessary to run those tests, the
others arent, not even to fulfill some prereqs.
So update 'ci/install-dependencies.sh' to install only 'libsvn-perl'
instead of 'git-svn' and its additional dependencies.
Note that this change has more important implications than merely not
installing three unnecessary packages, as it keeps our builds working
with Travis CI's Xenial images. In our '.travis.yml' we never
explicitly specified which Linux image we want to use to run our Linux
build jobs, and so far they have been run on the default Ubuntu 14.04
Trusty image. However, 14.04 just reached its EOL, and Travis CI has
already began the transition to use 16.04 Xenial as the default Linux
build environment [1]. Alas, our Linux Clang and GCC build jobs can't
simply 'apt-get install git-svn' in the current Xenial images [2],
like they did in the Trusty images, and, consequently, fail.
Installing only 'libsvn-perl' avoids this issue, while the 'git svn'
tests are still run as they should.

[2] 'apt-get install git-svn' in the Xenial image fails with:
The following packages have unmet dependencies:
git-svn : Depends: git (< 1:2.7.4-.)
E: Unable to correct problems, you have held broken packages.
The reason is that both the Trusty and Xenial images contain the
'git' package installed from 'ppa:git-core/ppa', so it's
considerably newer than the 'git' package in the corresponding
standard Ubuntu package repositories. The difference is that the
Trusty image still contains these third-party apt repositories, so
the 'git-svn' package was installed from the same PPA, and its
version matched the version of the already installed 'git'
package. In the Xenial image, however, these third-party
apt-repositories are removed (to reduce the risk of unrelated
interference and faster 'apt-get update') [3], and the version of
the 'git-svn' package coming from the standard Ubuntu package
repositories doesn't match the much more recent version of the
'git' package installed from the PPA, resulting in this dependecy
error.
Adding back the 'ppa:git-core/ppa' package repository would solve
this dependency issue as well, but since the troublesome package
happens to be unnecessary, not installing it in the first place is
better.
