transport: make transport vtable more privateJonathan Tan Thu, 14 Dec 2017 21:44:45 +0000 (13:44 -0800)

transport: make transport vtable more private

Move the definition of the transport-specific functions provided by
transports, whether declared in transport.c or transport-helper.c, into
an internal header. This means that transport-using code (as opposed to
transport-declaring code) can no longer access these functions (without
importing the internal header themselves), making it clear that they
should use the transport_*() functions instead, and also allowing the
interface between the transport mechanism and an individual transport to
independently evolve.

This is superficially a reversal of commit 824d5776c3f2 ("Refactor
struct transport_ops inlined into struct transport", 2007-09-19).
However, the scope of the involved variables was neither affected nor
discussed in that commit, and I think that the advantages in making
those functions more private outweigh the advantages described in that
commit's commit message. A minor additional point is that the code has
gotten more complicated since then, in that the function-pointer
variables are potentially mutated twice (once initially and once if
transport_take_over() is invoked), increasing the value of corralling
them into their own struct.

clone, fetch: remove redundant transport check

Prior to commit a2d725b7bdf7 ("Use an external program to implement
fetching with curl", 2009-08-05), if Git was compiled with NO_CURL, the
get_refs_list and fetch methods in struct transport might not be
populated, hence the checks in clone and fetch. After that commit, all
transports populate get_refs_list and fetch, making the checks in clone
and fetch redundant. Remove those checks.

t/lib-git-svn.sh: improve svnserve tests with parallel make test

Setting SVNSERVE_PORT enables several tests which require a local
svnserve daemon to be run (in t9113 & t9126). The tests share setup of
the local svnserve via `start_svnserve()`. The function uses svnserve's
`--listen-once` option, which causes svnserve to accept one connection
on the port, serve it, and exit. When running the tests in parallel
this fails if one test tries to start svnserve while the other is still
running.

Use the test number as the svnserve port (similar to httpd tests) to
avoid port conflicts. Developers can set GIT_TEST_SVNSERVE to any value
other than 'false' or 'auto' to enable these tests.

Compiled test helpers in t/helper are out of sync with the .gitignore

but the explicit .gitignore file is not updated in the same commit, or
when you forget to 'make clean' before checking out a different version
of git, as the different version may have a different explicit list of

Fix this by having an overly broad ignore pattern in that directory:

travis-ci: use 'set -x' in 'ci/*' scripts for extra tracing output

While the build logic was embedded in our '.travis.yml', Travis CI
used to produce a nice trace log including all commands executed in
those embedded scriptlets. Since 657343a60 (travis-ci: move Travis CI
code into dedicated scripts, 2017-09-10), however, we only see the
name of the dedicated scripts, but not what those scripts are actually
doing, resulting in a less useful trace log. A patch later in this
series will move setting environment variables from '.travis.yml' to
the 'ci/*' scripts, so not even those will be included in the trace
log.

Use 'set -x' in 'ci/lib-travisci.sh', which is sourced in most other
'ci/*' scripts, so we get trace log about the commands executed in all
of those scripts.

travis-ci: set GIT_TEST_HTTPD in 'ci/lib-travisci.sh'SZEDER Gábor Mon, 11 Dec 2017 23:34:46 +0000 (00:34 +0100)

travis-ci: set GIT_TEST_HTTPD in 'ci/lib-travisci.sh'

Commit 657343a60 (travis-ci: move Travis CI code into dedicated
scripts, 2017-09-10) converted '.travis.yml's default 'before_install'
scriptlet to the 'ci/install-dependencies.sh' script, and while doing
so moved setting GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang
Linux build jobs to that script. This is wrong for two reasons:

- The purpose of that script is, as its name suggests, to install
dependencies, not to set any environment variables influencing
which tests should be run (though, arguably, this was already an
issue with the original 'before_install' scriptlet).

- Setting the variable has no effect anymore, because that script is
run in a separate shell process, and the variable won't be visible
in any of the other scripts, notably in 'ci/run-tests.sh'
responsible for, well, running the tests.

Luckily, this didn't have a negative effect on our Travis CI build
jobs, because GIT_TEST_HTTPD is a tri-state variable defaulting to
"auto" and a functioning web server was installed in those Linux build
jobs, so the httpd tests were run anyway.

Apparently the httpd tests run just fine without GIT_TEST_HTTPD being
set, therefore we could simply remove this environment variable.
However, if a bug were to creep in to change the Travis CI build
environment to run the tests as root or to not install Apache, then
the httpd tests would be skipped and the build job would still
succeed. We would only notice if someone actually were to look
through the build job's trace log; but who would look at the trace log
of a successful build job?!

Since httpd tests are important, we do want to run them and we want to
be loudly reminded if they can't be run. Therefore, move setting
GIT_TEST_HTTPD=YesPlease for the 64-bit GCC and Clang Linux build jobs
to 'ci/lib-travisci.sh' to ensure that the build job fails when the
httpd tests can't be run. (We could set it in 'ci/run-tests.sh' just
as well, but it's better to keep all environment variables in one
place in 'ci/lib-travisci.sh'.)

travis-ci: move setting environment variables to 'ci... SZEDER Gábor Mon, 11 Dec 2017 23:34:45 +0000 (00:34 +0100)

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.

travis-ci: introduce a $jobname variable for 'ci/*... SZEDER Gábor Mon, 11 Dec 2017 23:34:44 +0000 (00:34 +0100)

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.

git-compat-util: introduce skip_to_optional_arg()

We often accept both a "--key" option and a "--key=<val>" option.

These options currently are parsed using something like:

if (!strcmp(arg, "--key")) {
/* do something */
} else if (skip_prefix(arg, "--key=", &arg)) {
/* do something with arg */
}

which is a bit cumbersome compared to just:

if (skip_to_optional_arg(arg, "--key", &arg)) {
/* do something with arg */
}

This also introduces skip_to_optional_arg_default() for the few
cases where something different should be done when the first
argument is exactly "--key" than when it is exactly "--key=".

In general it is better for UI consistency and simplicity if
"--key" and "--key=" do the same thing though, so that using
skip_to_optional_arg() should be encouraged compared to
skip_to_optional_arg_default().

Note that these functions can be used to parse any "key=value"
string where "key" is also considered as valid, not just
command line options.

clone: support 'clone --shared' from a worktreeEric Sunshine Mon, 11 Dec 2017 23:16:12 +0000 (18:16 -0500)

clone: support 'clone --shared' from a worktree

When worktree functionality was originally implemented, the possibility
of 'clone --local' from within a worktree was overlooked, with the
result that the location of the "objects" directory of the source
repository was computed incorrectly, thus the objects could not be
copied or hard-linked by the clone. This shortcoming was addressed by
744e469755 (clone: allow --local from a linked checkout, 2015-09-28).

However, the related case of 'clone --shared' (despite being handled
only a few lines away from the 'clone --local' case) was not fixed by
744e469755, with a similar result of the "objects" directory location
being incorrectly computed for insertion into the 'alternates' file.
Fix this.

t/Makefile: introduce TEST_SHELL_PATHJeff King Fri, 8 Dec 2017 10:47:22 +0000 (05:47 -0500)

t/Makefile: introduce TEST_SHELL_PATH

You may want to run the test suite with a different shell
than you use to build Git. For instance, you may build with
SHELL_PATH=/bin/sh (because it's faster, or it's what you
expect to exist on systems where the build will be used) but
want to run the test suite with bash (e.g., since that
allows using "-x" reliably across the whole test suite).
There's currently no good way to do this.

You might think that doing two separate make invocations,
like:

make &&
make -C t SHELL_PATH=/bin/bash

would work. And it _almost_ does. The second make will see
our bash SHELL_PATH, and we'll use that to run the
individual test scripts (or tell prove to use it to do so).
So far so good.

But this breaks down when "--tee" or "--verbose-log" is
used. Those options cause the test script to actually
re-exec itself using $SHELL_PATH. But wait, wouldn't our
second make invocation have set SHELL_PATH correctly in the
environment?

Yes, but test-lib.sh sources GIT-BUILD-OPTIONS, which we
built during the first "make". And that overrides the
environment, giving us the original SHELL_PATH again.

Let's introduce a new variable that lets you specify a
specific shell to be run for the test scripts. Note that we
have to touch both the main and t/ Makefiles, since we have
to record it in GIT-BUILD-OPTIONS in one, and use it in the
latter.

test-lib: make "-x" work with "--verbose-log"

The "-x" tracing option implies "--verbose". This is a
problem when running under a TAP harness like "prove", where
we need to use "--verbose-log" instead. Instead, let's
handle this the same way we do for --valgrind, including the
recent fix from 88c6e9d31c (test-lib: --valgrind should not
override --verbose-log, 2017-09-05). Namely, let's enable
--verbose only when we know there isn't a more specific
verbosity option indicated.

Note that we also have to tweak `want_trace` to turn it on
(previously we just lumped $verbose_log in with $verbose,
but now we don't necessarily auto-set the latter).

t5615: avoid re-using descriptor 4Jeff King Fri, 8 Dec 2017 10:47:13 +0000 (05:47 -0500)

t5615: avoid re-using descriptor 4

File descriptors 3 and 4 are special in our test suite, as
they link back to the test script's original stdout and
stderr. Normally this isn't something tests need to worry
about: they are free to clobber these descriptors for
sub-commands without affecting the overall script.

But there's one very special thing about descriptor 4: since
d88785e424 (test-lib: set BASH_XTRACEFD automatically,
2016-05-11), we ask bash to output "set -x" output to it by
number. This goes to _any_ descriptor 4, even if it no
longer points to the place it did when we set BASH_XTRACEFD.

But in t5615, we run a shell loop with descriptor 4
redirected. As a result, t5615 works with non-bash shells
even with "-x". And it works with bash without "-x". But the
combination of "bash t5615-alternate-env.sh -x" gets a test
failure (because our "set -x" output pollutes one of the
files).

We can fix this by using any descriptor _except_ the magical
4. So let's switch arbitrarily to using 5/6 in this loop,
not 3/4.

Another alternative is to use a different descriptor for
BASH_XTRACEFD. But picking an unused one turns out to be
hard. Most shells limit us to 9 numbered descriptors. Bash
can handle more, but:

- while the BASH_XTRACEFD is specific to bash, GIT_TRACE=4
has a similar problem, and would affect all shells

- constructs like "999>/dev/null" are synticatically
invalid to non-bash shells. So we have to actually bury
it inside an eval, which creates more complications.

Of the numbers 1-9, you might think that "9" would be less
used than "4". But it's not; many of our scripts use
descriptors 8 and 9 (probably under the assumption that they
are high and therefore unused). The least-used descriptor is
currently "7". We could switch to that, but we're just
trading one magic number for another.

test-lib: silence "-x" cleanup under bashJeff King Fri, 8 Dec 2017 10:47:08 +0000 (05:47 -0500)

test-lib: silence "-x" cleanup under bash

When the test suite's "-x" option is used with bash, we end
up seeing cleanup cruft in the output:

$ bash t0001-init.sh -x
[...]
++ diff -u expected actual
+ test_eval_ret_=0
+ want_trace
+ test t = t
+ test t = t
+ set +x
ok 42 - re-init from a linked worktree

This ranges from mildly annoying (for a successful test) to
downright confusing (when we say "last command exited with
error", but it's really 5 commands back).

We normally are able to suppress this cleanup. As the
in-code comment explains, we can't convince the shell not to
print it, but we can redirect its stderr elsewhere.

But since d88785e424 (test-lib: set BASH_XTRACEFD
automatically, 2016-05-11), that doesn't hold for bash. It
sends the "set -x" output directly to descriptor 4, not to
stderr.

We can fix this by also redirecting descriptor 4, and
paying close attention to which commands redirected and
which are not (see the updated comment).

Two alternatives I considered and rejected:

- unsetting and setting BASH_XTRACEFD; doing so closes the
descriptor, which we must avoid

- we could keep everything in a single block as before,
redirect 4>/dev/null there, but retain 5>&4 as a copy.
And then selectively restore 4>&5 for commands which
should be allowed to trace. This would work, but the
descriptor swapping seems unnecessarily confusing.

When a user tries to rename a branch that has a "bad name" (e.g.,

So, update the warning message shown to be more precise that only a copy

worktree: invoke post-checkout hook (unless --no-checkout)

git-clone and git-checkout both invoke the post-checkout hook following
a successful checkout, yet git-worktree neglects to do so even though it
too "checks out" the worktree. Fix this oversight.

Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

launch_editor(): indicate that Git waits for user input

When a graphical GIT_EDITOR is spawned by a Git command that opens
and waits for user input (e.g. "git rebase -i"), then the editor window
might be obscured by other windows. The user might be left staring at
the original Git terminal window without even realizing that s/he needs
to interact with another window before Git can proceed. To this user Git
appears hanging.

Print a message that Git is waiting for editor input in the original
terminal and get rid of it when the editor returns, if the terminal
supports erasing the last line. Also, make sure that our message is
terminated with a whitespace so that any message the editor may show
upon starting up will be kept separate from our message.

Power users might not want to see this message or their editor might
already print such a message (e.g. emacsclient). Allow these users to
suppress the message by disabling the "advice.waitingForEditor" config.

The standard advise() function is not used here as it would always add
a newline which would make deleting the message harder.

diff-tree: read the index so attribute checks work in bare repositories

A regression was introduced in 557a5998d (submodule: remove
gitmodules_config, 2017-08-03) to how attribute processing was handled
in bare repositories when running the diff-tree command.

By default the attribute system will first try to read ".gitattribute"
files from the working tree and then falls back to reading them from the
index if there isn't a copy checked out in the worktree. Prior to
557a5998d the index was read as a side effect of the call to
'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.

Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.

Fix this by explicitly reading the index during the setup of diff-tree.

Merge branch 'jk/fewer-pack-rescan'

Internaly we use 0{40} as a placeholder object name to signal the
codepath that there is no such object (e.g. the fast-forward check
while "git fetch" stores a new remote-tracking ref says "we know
there is no 'old' thing pointed at by the ref, as we are creating
it anew" by passing 0{40} for the 'old' side), and expect that a
codepath to locate an in-core object to return NULL as a sign that
the object does not exist. A look-up for an object that does not
exist however is quite costly with a repository with large number
of packfiles. This access pattern has been optimized.

* jk/fewer-pack-rescan:
sha1_file: fast-path null sha1 as a missing object
everything_local: use "quick" object existence check
p5551: add a script to test fetch pack-dir rescans
t/perf/lib-pack: use fast-import checkpoint to create packs
