SZEDER Gábor fb9d7431cf travis-ci: build with GCC 4.8 as well
C99 'for' loop initial declaration, i.e. 'for (int i = 0; i < n; i++)',
is not allowed in Git's codebase yet, to maintain compatibility with
some older compilers.

Our Travis CI builds used to catch 'for' loop initial declarations,
because the GETTEXT_POISON job has always built Git with the default
'cc', which in Travis CI's previous default Linux image (based on
Ubuntu 14.04 Trusty) is GCC 4.8, and that GCC version errors out on
this construct (not only with DEVELOPER=1, but with our default CFLAGS
as well).  Alas, that's not the case anymore, becase after 14.04's EOL
Travis CI's current default Linux image is based on Ubuntu 16.04
Xenial [1] and its default 'cc' is now GCC 5.4, which, just like all
later GCC and Clang versions, simply accepts this construct, even if
we don't explicitly specify '-std=c99'.

Ideally we would adjust our CFLAGS used with DEVELOPER=1 to catch this
undesired construct already when contributors build Git on their own
machines.  Unfortunately, however, there seems to be no compiler
option that would catch only this particular construct without choking
on many other things, e.g. while a later compiler with '-std=c90'
and/or '-ansi' does catch this construct, it can't build Git because
of several screenfulls of other errors.

Add the 'linux-gcc-4.8' job to Travis CI, in order to build Git with
GCC 4.8, and thus to timely catch any 'for' loop initial declarations.
To catch those it's sufficient to only build Git with GCC 4.8, so
don't run the test suite in this job, because 'make test' takes rather
long [2], and it's already run five times in other jobs, so we
wouldn't get our time's worth.

[1] The Azure Pipelines builds have been using Ubuntu 16.04 images
    from the start, so I belive they never caught 'for' loop initial
    declarations.

[2] On Travis CI 'make test' alone would take about 9 minutes in this
    new job (without running httpd, Subversion, and P4 tests).  For
    comparison, starting the job and building Git with GCC 4.8 takes
    only about 2 minutes.

Johannes Schindelin 50b206371d travis: remove the hack to build the Windows job on Azure Pipelines
Since Travis did not support Windows (and now only supports very limited
Windows jobs, too limited for our use, the test suite would time out
*all* the time), we added a hack where a Travis job would trigger an
Azure Pipeline (which back then was still called VSTS Build), wait for
it to finish (or time out), and download the log (if available).

Needless to say that it was a horrible hack, necessitated by a bad
situation.

Nowadays, however, we have Azure Pipelines support, and do not need that
hack anymore. So let's retire it.

SZEDER Gábor 2000ac9fbf travis-ci: switch to Xcode 10.1 macOS image
When building something with GCC installed from Homebrew in the
default macOS (with Xcode 9.4) image on Travis CI, it errors out with
something like this:

  /usr/local/Cellar/gcc/8.1.0/lib/gcc/8/gcc/x86_64-apple-darwin17.5.0/8.1.0/include-fixed/stdio.h:78:10: fatal error: _stdio.h: No such file or directory
   #include <_stdio.h>
            ^~~~~~~~~~

This seems to be a common problem affecting several projects, and the
common solution is to use a Travis CI macOS image with more recent
Xcode version, e.g. 10 or 10.1.

While we don't use such a GCC yet, in the very next patch we will, so
switch our OSX build jobs to use the Xcode 10.1 image.  Compared to
the Xcode 10 image, this has the benefit that it comes with GCC (v8.2)
preinstalled from Homebrew.

Junio C Hamano 954932667d Merge branch 'ab/dynamic-gettext-poison'
Our testing framework uses a special i18n "poisoned localization"
feature to find messages that ought to stay constant but are
incorrectly marked to be translated.  This feature has been made
into a runtime option (it used to be a compile-time option).

* ab/dynamic-gettext-poison:
  Makefile: ease dynamic-gettext-poison transition
  i18n: make GETTEXT_POISON a runtime option
2018-11-19 16:24:39 +09:00
Ævar Arnfjörð Bjarmason 6cdccfce1e i18n: make GETTEXT_POISON a runtime option
Change the GETTEXT_POISON compile-time + runtime GIT_GETTEXT_POISON
test parameter to only be a GIT_TEST_GETTEXT_POISON=<non-empty?>
runtime parameter, to be consistent with other parameters documented
in "Running tests with special setups" in t/README.

When I added GETTEXT_POISON in bb946bba76 ("i18n: add GETTEXT_POISON
to simulate unfriendly translator", 2011-02-22) I was concerned with
ensuring that the _() function would get constant folded if NO_GETTEXT
was defined, and likewise that GETTEXT_POISON would be compiled out
unless it was defined.

But as the benchmark in my [1] shows doing a one-off runtime
getenv("GIT_TEST_[...]") is trivial, and since GETTEXT_POISON was
originally added the GIT_TEST_* env variables have become the common
idiom for turning on special test setups.

So change GETTEXT_POISON to work the same way. Now the
GETTEXT_POISON=YesPlease compile-time option is gone, and running the
tests with GIT_TEST_GETTEXT_POISON=[YesPlease|] can be toggled on/off
without recompiling.

This allows for conditionally amending tests to test with/without
poison, similar to what 859fdc0c3c ("commit-graph: define
GIT_TEST_COMMIT_GRAPH", 2018-08-29) did for GIT_TEST_COMMIT_GRAPH. Do
some of that, now we e.g. always run the t0205-gettext-poison.sh test.

I did enough there to remove the GETTEXT_POISON prerequisite, but its
inverse C_LOCALE_OUTPUT is still around, and surely some tests using
it can be converted to e.g. always set GIT_TEST_GETTEXT_POISON=.

Notes on the implementation:

 * We still compile a dedicated GETTEXT_POISON build in Travis
   CI. Perhaps this should be revisited and integrated into the
   "linux-gcc" build, see ae59a4e44f ("travis: run tests with
   GIT_TEST_SPLIT_INDEX", 2018-01-07) for prior art in that area. Then
   again maybe not, see [2].

 * We now skip a test in t0000-basic.sh under
   GIT_TEST_GETTEXT_POISON=YesPlease that wasn't skipped before. This
   test relies on C locale output, but due to an edge case in how the
   previous implementation of GETTEXT_POISON worked (reading it from
   GIT-BUILD-OPTIONS) wasn't enabling poison correctly. Now it does,
   and needs to be skipped.

 * The getenv() function is not reentrant, so out of paranoia about
   code of the form:

       printf(_("%s"), getenv("some-env"));

   call use_gettext_poison() in our early setup in git_setup_gettext()
   so we populate the "poison_requested" variable in a codepath that's
   won't suffer from that race condition.

 * We error out in the Makefile if you're still saying
   GETTEXT_POISON=YesPlease to prompt users to change their
   invocation.

 * We should not print out poisoned messages during the test
   initialization itself to keep it more readable, so the test library
   hides the variable if set in $GIT_TEST_GETTEXT_POISON_ORIG during
   setup. See [3].

See also [4] for more on the motivation behind this patch, and the
history of the GETTEXT_POISON facility.

SZEDER Gábor 0f0c51181d travis-ci: install packages in 'ci/install-dependencies.sh'
Ever since we started using Travis CI, we specified the list of
packages to install in '.travis.yml' via the APT addon.  While running
our builds on Travis CI's container-based infrastructure we didn't
have another choice, because that environment didn't support 'sudo',
and thus we didn't have permission to install packages ourselves.  With
the switch to the VM-based infrastructure in the previous patch we do
get a working 'sudo', so we can install packages by running 'sudo
apt-get -y install ...' as well.

Let's make use of this and install necessary packages in
'ci/install-dependencies.sh', so all the dependencies (i.e. both
packages and "non-packages" (P4 and Git-LFS)) are handled in the same
file.  Install gcc-8 only in the 'linux-gcc' build job; so far it has
been unnecessarily installed in the 'linux-clang' build job as well.
Print the versions of P4 and Git-LFS conditionally, i.e. only when
they have been installed; with this change even the static analysis
and documentation build jobs start using 'ci/install-dependencies.sh'
to install packages, and neither of these two build jobs depend on and
thus install those.

This change will presumably be beneficial for the upcoming Azure
Pipelines integration [1]: preliminary versions of that patch series
run a couple of 'apt-get' commands to install the necessary packages
before running 'ci/install-dependencies.sh', but with this patch it
will be sufficient to run only 'ci/install-dependencies.sh'.

SZEDER Gábor 3c93b82920 travis-ci: build Git during the 'script' phase
Ever since we started building and testing Git on Travis CI (522354d70
(Add Travis CI support, 2015-11-27)), we build Git in the
'before_script' phase and run the test suite in the 'script' phase
(except in the later introduced 32 bit Linux and Windows build jobs,
where we build in the 'script' phase').

Contrarily, the Travis CI practice is to build and test in the
'script' phase; indeed Travis CI's default build command for the
'script' phase of C/C++ projects is:

  ./configure && make && make test

The reason why Travis CI does it this way and why it's a better
approach than ours lies in how unsuccessful build jobs are
categorized.  After something went wrong in a build job, its state can
be:

  - 'failed', if a command in the 'script' phase returned an error.
    This is indicated by a red 'X' on the Travis CI web interface.

  - 'errored', if a command in the 'before_install', 'install', or
    'before_script' phase returned an error, or the build job exceeded
    the time limit.  This is shown as a red '!' on the web interface.

This makes it easier, both for humans looking at the Travis CI web
interface and for automated tools querying the Travis CI API, to
decide when an unsuccessful build is our responsibility requiring
human attention, i.e. when a build job 'failed' because of a compiler
error or a test failure, and when it's caused by something beyond our
control and might be fixed by restarting the build job, e.g. when a
build job 'errored' because a dependency couldn't be installed due to
a temporary network error or because the OSX build job exceeded its
time limit.

The drawback of building Git in the 'before_script' phase is that one
has to check the trace log of all 'errored' build jobs, too, to see
what caused the error, as it might have been caused by a compiler
error.  This requires additional clicks and page loads on the web
interface and additional complexity and API requests in automated
tools.

Therefore, move building Git from the 'before_script' phase to the
'script' phase, updating the script's name accordingly as well.
'ci/run-builds.sh' now becomes basically empty, remove it.  Several of
our build job configurations override our default 'before_script' to
do nothing; with this change our default 'before_script' won't do
anything, either, so remove those overriding directives as well.

SZEDER Gábor e3371e9260 travis-ci: move setting environment variables to 'ci/lib-travisci.sh'
Our '.travis.yml's 'env.global' section sets a bunch of environment
variables for all build jobs, though none of them actually affects all
build jobs.  It's convenient for us, and in most cases it works just
fine, because irrelevant environment variables are simply ignored.

However, $GIT_SKIP_TESTS is an exception: it tells the test harness to
skip the two test scripts that are prone to occasional failures on
OSX, but as it's set for all build jobs those tests are not run in any
of the build jobs that are capable to run them reliably, either.

Therefore $GIT_SKIP_TESTS should only be set in the OSX build jobs,
but those build jobs are included in the build matrix implicitly (i.e.
by combining the matrix keys 'os' and 'compiler'), and there is no way
to set an environment variable only for a subset of those implicit
build jobs.  (Unless we were to add new scriptlets to '.travis.yml',
which is exactly the opposite direction that we took with commit
657343a60 (travis-ci: move Travis CI code into dedicated scripts,
2017-09-10)).

So move setting $GIT_SKIP_TESTS to 'ci/lib-travisci.sh', where it can
trivially be set only for the OSX build jobs.

Furthermore, move setting all other environment variables from
'.travis.yml' to 'ci/lib-travisci.sh', too, because a couple of
environment variables are already set there, and this way all
environment variables will be set in the same place.  All the logic
controlling our builds is already in the 'ci/*' scripts anyway, so
there is really no good reason to keep the environment variables
separately.

SZEDER Gábor bf427a9451 travis-ci: introduce a $jobname variable for 'ci/*' scripts
A couple of 'ci/*' scripts are shared between different build jobs:
'ci/lib-travisci.sh', being a common library, is sourced from almost
every script, while 'ci/install-dependencies.sh', 'ci/run-build.sh'
and 'ci/run-tests.sh' are shared between the "regular" GCC and Clang
Linux and OSX build jobs, and the latter two scripts are used in the
GETTEXT_POISON Linux build job as well.

Our builds could benefit from these shared scripts being able to
easily tell which build job they are taking part in.  Now, it's
already quite easy to tell apart Linux vs OSX and GCC vs Clang build
jobs, but it gets trickier with all the additional Linux-based build
jobs included explicitly in the build matrix.

Unfortunately, Travis CI doesn't provide much help in this regard.
The closest we've got is the $TRAVIS_JOB_NUMBER variable, the value of
which is two dot-separated integers, where the second integer
indicates a particular build job.  While it would be possible to use
that second number to identify the build job in our shared scripts, it
doesn't seem like a good idea to rely on that:

  - Though the build job numbering sequence seems to be stable so far,
    Travis CI's documentation doesn't explicitly states that it is
    indeed stable and will remain so in the future.  And even if it
    were stable,

  - if we were to remove or insert a build job in the middle, then the
    job numbers of all subsequent build jobs would change accordingly.

So roll our own means of simple build job identification and introduce
the $jobname environment variable in our builds, setting it in the
environments of the explicitly included jobs in '.travis.yml', while
constructing one in 'ci/lib-travisci.sh' as the combination of the OS
and compiler name for the GCC and Clang Linux and OSX build jobs.  Use
$jobname instead of $TRAVIS_OS_NAME in scripts taking different
actions based on the OS and build job (when installing P4 and Git LFS
dependencies and including them in $PATH).  The following two patches
will also rely on $jobname.

Lars Schneider 029aeeed55 travis-ci: build and test Git on Windows
Most Git developers work on Linux and they have no way to know if their
changes would break the Git for Windows build. Let's fix that by adding
a job to TravisCI that builds and tests Git on Windows. Unfortunately,
TravisCI does not support Windows.

Therefore, we did the following:
* Johannes Schindelin set up a Visual Studio Team Services build
  sponsored by Microsoft and made it accessible via an Azure Function
  that speaks a super-simple API. We made TravisCI use this API to
  trigger a build, wait until its completion, and print the build and
  test results.
* A Windows build and test run takes up to 3h and TravisCI has a timeout
  after 50min for Open Source projects. Since the TravisCI job does not
  use heavy CPU/memory/etc. resources, the friendly TravisCI folks
  extended the job timeout for git/git to 3h.

Things, that would need to be done:
* Someone with write access to https://travis-ci.org/git/git would need
  to add the secret token as "GFW_CI_TOKEN" variable in the TravisCI
  repository setting [1]. Afterwards the build should just work.

Things, that might need to be done:
* The Windows box can only process a single build at a time. A second
  Windows build would need to wait until the first finishes. This
  waiting time and the build time after the wait could exceed the 3h
  threshold. If this is a problem, then it is likely to happen every day
  as usually multiple branches are pushed at the same time (pu/next/
  master/maint). I cannot test this as my TravisCI account has the 50min
  timeout. One solution could be to limit the number of concurrent
  TravisCI jobs [2].

and on 32-bit systems: our assumption that `unsigned long` can hold
64-bit values turned out to be wrong.

This could have been caught earlier if we had a Continuous Testing
set up that includes a build and test run on 32-bit Linux.

Let's do this (and take care of the Windows build later). This patch
asks Travis CI to install a Docker image with 32-bit libraries and then
goes on to build and test Git using this 32-bit setup.

Lars Schneider 672f51cb83 travis-ci: fix Perforce install on macOS
The `perforce` and `perforce-server` package were moved from brew [1][2]
to cask [3]. Teach TravisCI the new location.

Perforce updates their binaries without version bumps. That made the
brew install (legitimately!) fail due to checksum mismatches. The
workaround is not necessary anymore as Cask [4] allows to disable the
checksum test for individual formulas.

Junio C Hamano f4db874d9a Merge branch 'jk/tap-verbose-fix'
The Travis CI configuration we ship ran the tests with --verbose
option but this risks non-TAP output that happens to be "ok" to be
misinterpreted as TAP signalling a test that passed.  This resulted
in unnecessary failure.  This has been corrected by introducing a
new mode to run our tests in the test harness to send the verbose
output separately to the log file.

Jeff King 041c72de10 travis: use --verbose-log test option
Because we run the tests via "prove", the output from
"--verbose" may interfere with our TAP output. Using
"--verbose-log" solves this while letting us retain our
on-disk log.

The TravisCI macOS build is broken because homebrew (a macOS dependency
manager) changed its internal directory structure [1]. This is a problem
because we modify the Perforce dependencies in the homebrew repository
before installing them.

Fix it by asking homebrew for its path instead of hardcoding it.

Johannes Schindelin e3efa94be9 perf: accommodate for MacOSX
As this developer has no access to MacOSX developer setups anymore,
Travis becomes the best bet to run performance tests on that OS.

However, on MacOSX /usr/bin/time is that good old BSD executable that
no Linux user cares about, as demonstrated by the perf-lib.sh's use
of GNU-ish extensions. And by the hard-coded path.

Let's just work around this issue by using gtime on MacOSX, the
Homebrew-provided GNU implementation onto which pretty much every
MacOSX power user falls back anyway.

To help other developers use Travis to run performance tests on
MacOSX, the .travis.yml file now sports a commented-out line that
installs GNU time via Homebrew.

The Git Travis CI OSX build always installs the latest versions of Git LFS and
Perforce via brew and the Linux build installs fixed versions. Consequently new
LFS/Perforce versions can break the OS X build even if there is no change in

Lars Schneider 6272ed3194 travis-ci: run previously failed tests first, then slowest to fastest
The Travis-CI machines are in a clean state in the beginning of every run
(transient by default). Use the Travis-CI cache feature to make the prove
state persistent across consecutive Travis-CI runs on the same branch.
This allows to run previously failed tests first and run remaining tests
in slowest to fastest order. As a result it is less likely that Travis-CI
needs to wait for a single test at the end which speeds up the test suite
execution by ~2 min.

Travis-CI can only cache entire directories. Prove stores the .prove file
always in the t/ directory but we don't want to cache the entire t/ directory.
Therefore we create a symlink from $HOME/travis-cache/.prove to t/.prove and
cache the $HOME/travis-cache directory.

Unfortunately the cache feature is only available (for free) on the
Travis-CI Linux environment.
