fetch tests: test --prune and refspec interactionÆvar Arnfjörð Bjarmason Fri, 9 Feb 2018 20:32:07 +0000 (20:32 +0000)

fetch tests: test --prune and refspec interaction

Add a test for the interaction between explicitly provided refspecs
and fetch.prune.

There's no point in adding this boilerplate to every combination of
unset/false/true, it's instructive and sufficient to show that no
matter if the variable is unset, false or true the refspec on the
command-line overrides any configuration variable.

fetch tests: add a tag to be deleted to the pruning tests

Add a tag to be deleted to the fetch --prune tests. The tag is always
kept for now, which is the expected behavior, but now I can add a test
for tag pruning in a later commit.

fetch tests: re-arrange arguments for future readability

Re-arrange the arguments to the test_configured_prune() function used
in this test to pass the arguments to --fetch last. A subsequent
change will test for more elaborate fetch arguments, including long
refspecs. It'll be more readable to be able to wrap those on a new
line of their own.

fetch tests: refactor in preparation for testing tag pruning

In a subsequent commit this function will learn to test for tag
pruning, prepare for that by making space for more variables, and
making it clear that "expected" here refers to branches.

remote: add a macro for "refs/tags/*:refs/tags/*"Ævar Arnfjörð Bjarmason Fri, 9 Feb 2018 20:32:03 +0000 (20:32 +0000)

remote: add a macro for "refs/tags/*:refs/tags/*"

Add a macro with the refspec string "refs/tags/*:refs/tags/*". There's
been a pre-defined struct version of this since e0aaa29ff3 ("Have a
constant extern refspec for "--tags"", 2008-04-17), but nothing that
could be passed to e.g. add_fetch_refspec().

This will be used in subsequent commits to avoid hardcoding this
string in multiple places.

fetch: stop accessing "remote" variable indirectlyÆvar Arnfjörð Bjarmason Fri, 9 Feb 2018 20:32:02 +0000 (20:32 +0000)

fetch: stop accessing "remote" variable indirectly

Access the "remote" variable passed to the fetch_one() directly rather
than through the gtransport wrapper struct constructed in this
function for other purposes.

This makes the code more readable, as it's now obvious that the remote
struct doesn't somehow get munged by the prepare_transport() function
above, which takes the "remote" struct as an argument and constructs
the "gtransport" struct, containing among other things the "remote"
struct.

A subsequent change will copy this pattern to access a new
remote->prune_tags field, but without the use of the gtransport
variable. It's useful once that change lands to see that the two
pieces of code behave exactly the same.

This pattern of accessing the container struct was added in
737c5a9cde ("fetch: make --prune configurable", 2013-07-13) when this
code was initially introduced.

fetch: trivially refactor assignment to ref_nrÆvar Arnfjörð Bjarmason Fri, 9 Feb 2018 20:32:01 +0000 (20:32 +0000)

fetch: trivially refactor assignment to ref_nr

Trivially refactor an assignment to make a subsequent patch
smaller. The "ref_nr" variable is initialized to 0 earlier, just as
"j" is, and "j" is only incremented in that loop, so this change isn't
a logic error.

This change simplifies a subsequent change, which will split the
incrementing of "ref_nr" into two blocks.

fetch: don't redundantly NULL something calloc() gave usÆvar Arnfjörð Bjarmason Fri, 9 Feb 2018 20:32:00 +0000 (20:32 +0000)

fetch: don't redundantly NULL something calloc() gave us

Stop redundantly NULL-ing the last element of the refs structure,
which was retrieved via calloc(), and is thus guaranteed to be
pre-NULL'd.

This code dates back to b888d61c83 ("Make fetch a builtin",
2007-09-10), where wasn't any reason to do this back then either, it's
just boilerplate left over from when git-fetch was initially
introduced.

The motivation for this change was to make a subsequent change which
would also modify the refs variable smaller, since it won't have to
copy this redundant "NULL the last + 1 item" pattern.

We may not end up keeping that change, but as this pattern is still
pointless, so let's fix it.

git-completion.bash: introduce __gitcomp_builtinNguyễn Thái Ngọc Duy Fri, 9 Feb 2018 11:01:43 +0000 (18:01 +0700)

git-completion.bash: introduce __gitcomp_builtin

This is a __gitcomp wrapper that will execute

git ... --git-completion-helper

to get the list of completable options. The call will be made only
once and cached to avoid performance issues, especially on Windows.

__gitcomp_builtin() allows callers to change its output a bit by adding
some more options, or removing some.

- Current --git-completion-helper for example does not output --no-foo
form, this has to be added manually by __gitcomp_builtin() callers
when necessary

- Some options from --git-completion-helper should only be available in
certain conditions (e.g. --continue and friends). __gitcomp_builtin()
callers can remove them if the conditions are not met.

rebase -p: fix incorrect commit message when calling `git merge`.

Since commit dd6fb0053 ("rebase -p: fix quoting when calling `git
merge`"), commit message of the merge commit being rebased is passed to
the merge command using a subshell executing 'git rev-parse --sq-quote'.

Double quotes are needed around this subshell so that, newlines are
kept for the git merge command.

Before this patch, following merge message:

"Merge mybranch into mynewbranch

Awesome commit."

becomes:

"Merge mybranch into mynewbranch Awesome commit."

after a rebase -p.

CodingGuidelines: mention "static" and "extern"Jeff King Thu, 8 Feb 2018 21:38:06 +0000 (16:38 -0500)

CodingGuidelines: mention "static" and "extern"

It perhaps goes without saying that file-local stuff should
be marked static, but it does not hurt to remind people.

Less obvious is that we are settling on "do not include
extern in function declarations". It is already the default
unless the function was previously declared static (but if
you are following a static declaration with an unmarked one,
you should think about why you are declaring the thing
twice). And so it just becomes an extra noise-word in our
header files.

We used to give the opposite advice, so there are quite a
few "extern" markers in early Git code. But this at least
makes a concrete suggestion that we can follow going
forward.

nobody is supposed to send those, and they are
indistinguishable from a flush in this interface).

Let's correct error messages which claim an unexpected EOF;
it's really an unexpected flush packet.

While we're here, let's also check "!line" instead of
"!len" in the second case. The two events should always

t: make 'test_i18ngrep' more informative on failureSZEDER Gábor Thu, 8 Feb 2018 15:56:56 +0000 (16:56 +0100)

t: make 'test_i18ngrep' more informative on failure

When 'test_i18ngrep' can't find the expected pattern, it exits
completely silently; when its negated form does find the pattern that
shouldn't be there, it prints the matching line(s) but otherwise exits
without any error message. This leaves the developer puzzled about
what could have gone wrong.

Make 'test_i18ngrep' more informative on failure by printing an error
message including the invoked 'grep' command and the contents of the
file it had to scan through.

Note that this "dump the scanned file" part is not quite perfect, as
it dumps only the file specified as the function's last positional
parameter, thus assuming that there is only a single file parameter.
I think that's a reasonable assumption to make, one that holds true in
the current code base. And even if someone were to scan multiple
files at once in the future, the worst thing that could happen is that
the verbose error message won't include the contents of all those
files, only the last one. Alas, we can't really do any better than
this, because checking whether the other positional parameters match a
filename can result in false positives: 't3400-rebase.sh' and
't3404-rebase-interactive.sh' contain one test each, where the
'test_i18ngrep's pattern verbatimly matches a file in the trash
directory.

t: validate 'test_i18ngrep's parameters

Some of the previous patches in this series fixed bogus
'test_i18ngrep' invocations:

- Two invocations where the tested git command's standard output is
directly piped into 'test_i18ngrep'. While convenient, this is an
antipattern, because the pipe hides the git command's exit code,
and the test could continue even if the command exited with error.

- Two invocations that had neither a filename parameter nor anything
piped into their standard input, yet both managed to remain
unnoticed for years. A third similarly bogus invocation is
currently lurking in 'pu' for a couple of weeks now.

Prevent similar mistakes in the future by validating 'test_i18ngrep's
parameters requiring that

- The last parameter names an existing file to be read, effectively
forbidding piping into 'test_i18ngrep'.

Note that this change will also forbid cases where 'test_i18ngrep'
would legitimately read its standard input, e.g. when its standard
input is redirected from a file, or when a git command's standard
output is first written to an intermediate file, which is then
preprocessed by a non-git command before the results are piped
into 'test_i18ngrep'. See two of the previous patches for the
only such cases we had in our test suite. However, reliably
preventing the piping antipattern is arguably more important than
supporting these cases, which can be easily worked around by
opening the file directly or using an intermediate file anyway.

- There are at least two parameters, not including the optional '!'
to negate the pattern. This ought to catch corner cases when
'test_i18ngrep' looks for the name of an existing file on its
standard input; the above check would miss this case becase the
filename as pattern would be the last parameter.

Note that this is not quite perfect, as it doesn't account for any
'grep --options' given as parameters. However, doing so would be
far too complicated, considering that patterns can start with
dashes as well, and in the majority of the cases we don't use any
such options anyway.

cause the test to fail if Git was built with a sufficiently old
libcurl version. The test's two ||-chained 'test_i18ngrep'
invocations are supposed to check that either one of the two patterns
is present in 'git clone's error message. As it happens, the first
invocation covers the error message from any reasonably up-to-date

parameter, isn't executed at all. Apparently no one has run the test
suite's httpd tests with such an old libcurl in the last 2+ years, or
at least they haven't bothered to notify us about the failed test.

git-sh-i18n: check GETTEXT_POISON before USE_GETTEXT_SCHEMEJeff King Tue, 6 Feb 2018 08:44:56 +0000 (03:44 -0500)

git-sh-i18n: check GETTEXT_POISON before USE_GETTEXT_SCHEME

Running "make NO_GETTEXT=1 GETTEXT_POISON=1" currently fails
t0205.

While it might seem nonsensical at first glance to both
poison and disable gettext, it's useful to be able to do a
poison test-run on a system that doesn't have gettext at
all. And it works fine for C programs; the problem is only
with the shell code.

The issue is that we check the baked-in USE_GETTEXT_SCHEME
value before GETTEXT_POISON. And when NO_GETTEXT is set, the
Makefile sets USE_GETTEXT_SCHEME to "fallthrough".

So one fix would be to have the Makefile just set
USE_GETTEXT_SCHEME to "poison" if GETTEXT_POISON is set.
But there are two problems with that:

1. USE_GETTEXT_SCHEME is actually a user-facing knob, so
conceivably somebody could override it with:

make USE_GETTEXT_SCHEME=gnu GETTEXT_POISON=1

which would do the wrong thing (though that's much less
likely than them having the variable set in their
config.mak and just overriding GETTEXT_POISON on the
command-line for a one-off test).

2. We don't actually bake GETTEXT_POISON in to the shell
library like we do for the C code. It checks
$GIT_GETTEXT_POISON at runtime, which is set up by the
test suite. So it makes sense to put the fix in the
runtime code, too, which would cover something like:

GIT_GETTEXT_POISON=foo git foo

It's not likely that people use the poison code outside
of running the test suite, but it's easy enough to make
this case work.

blame: tighten command line parserJunio C Hamano Mon, 5 Feb 2018 23:12:11 +0000 (15:12 -0800)

blame: tighten command line parser

The command line parser of "git blame" is prepared to take an
ancient odd argument order "blame <path> <rev>" in addition to the
usual "blame [<rev>] <path>". It has at least two negative
ramifications:

- In order to tell these two apart, it checks if the last command
line argument names a path in the working tree, using
file_exists(). However, "blame <rev> <path>" is a request to
explain each and every line in the contents of <path> stored in
revision <rev> and does not need to have a working tree version
of the file. A check with file_exists() is simply wrong.

- To coerce that mistaken file_exists() check to work, the code
calls setup_work_tree() before doing so, because the path it has
is relative to the top-level of the project tree. However,
"blame <rev> <path>" MUST be usable even in a bare repository,
and there is no reason for letting setup_work_tree() complain
and die with "This operation must be run in a work tree".

To correct the former, switch to check if the last token is a
revision (and if so, parse arguments using "blame <path> <rev>"
rule). Correct the latter by getting rid of setup_work_tree() and
file_exists() check--the only case the call to this function matters
is when we are running "blame <path>" (i.e. no starting revision and
asking to blame the working tree file at <path>, digging through the
HEAD revision), but there is a call in setup_scoreboard() just
before it calls fake_working_tree_commit().

dir.c: ignore paths containing .git when invalidating... Nguyễn Thái Ngọc Duy Wed, 7 Feb 2018 09:21:40 +0000 (16:21 +0700)

dir.c: ignore paths containing .git when invalidating untracked cache

read_directory() code ignores all paths named ".git" even if it's not
a valid git repository. See treat_path() for details. Since ".git" is
basically invisible to read_directory(), when we are asked to
invalidate a path that contains ".git", we can safely ignore it
because the slow path would not consider it anyway.

This helps when fsmonitor is used and we have a real ".git" repo at
worktree top. Occasionally .git/index will be updated and if the
fsmonitor hook does not filter it, untracked cache is asked to
invalidate the path ".git/index".

Without this patch, we invalidate the root directory unncessarily,
which:

- makes read_directory() fall back to slow path for root directory
(slower)

- makes the index dirty (because UNTR extension is updated). Depending
on the index size, writing it down could also be slow.

A note about the new "safe_path" knob. Since this new check could be
relatively expensive, avoid it when we know it's not needed. If the
path comes from the index, it can't contain ".git". If it does
contain, we may be screwed up at many more levels, not just this one.

dir.c: don't flag the index as dirty for changes to the untracked cache

The untracked cache saves its current state in the UNTR index extension.
Currently, _any_ change to that state causes the index to be flagged as dirty
and written out to disk. Unfortunately, the cost to write out the index can
exceed the savings gained by using the untracked cache. Since it is a cache
that can be updated from the current state of the working directory, there is
no functional requirement that the index be written out for every change to the
untracked cache.

Update the untracked cache logic so that it no longer forces the index to be
written to disk except in the case where the extension is being turned on or
off. When some other git command requires the index to be written to disk, the
untracked cache will take advantage of that to save it's updated state as well.
This results in a performance win when looked at over common sequences of git
commands (ie such as a status followed by add, commit, etc).

After this patch, all the logic to track statistics for the untracked cache
could be removed as it is only used by debug tracing used to debug the untracked
cache.

daemon: add --log-destination=(stderr|syslog|none)Lucas Werkmeister Sun, 4 Feb 2018 18:30:37 +0000 (19:30 +0100)

daemon: add --log-destination=(stderr|syslog|none)

This new option can be used to override the implicit --syslog of
--inetd, or to disable all logging. (While --detach also implies
--syslog, --log-destination=stderr with --detach is useless since
--detach disassociates the process from the original stderr.) --syslog
is retained as an alias for --log-destination=syslog.

--log-destination always overrides implicit --syslog regardless of
option order. This is different than the “last one wins” logic that
applies to some implicit options elsewhere in Git, but should hopefully
be less confusing. (I also don’t know if *all* implicit options in Git
follow “last one wins”.)

The combination of --inetd with --log-destination=stderr is useful, for
instance, when running `git daemon` as an instanced systemd service
(with associated socket unit). In this case, log messages sent via
syslog are received by the journal daemon, but run the risk of being
processed at a time when the `git daemon` process has already exited
(especially if the process was very short-lived, e.g. due to client
error), so that the journal daemon can no longer read its cgroup and
attach the message to the correct systemd unit (see systemd/systemd#2913
[1]). Logging to stderr instead can solve this problem, because systemd
can connect stderr directly to the journal daemon, which then already
knows which unit is associated with this stream.

reset --hard: make use of the pretty machineryThomas Gummerer Thu, 1 Feb 2018 20:57:21 +0000 (20:57 +0000)

reset --hard: make use of the pretty machinery

reset --hard currently uses its own logic for printing the first line of
the commit message in its output. Instead of just using the first line,
use the pretty machinery to create the output.

In addition to the easier to follow code, this makes the output more
consistent with other commands that print the title of the commit, such
as 'git commit --oneline' or 'git checkout', which both use
'pp_commit_easy()' with the CMIT_FMT_ONELINE modifier.

It is a slight change of the output if the second line of the commit
message is not a blank line, i.e. if the commit message is

foo
bar

previously we would print "HEAD is now at 000000 foo", while after
this change we print "HEAD is now at 000000 foo bar", same as 'git log
--oneline' shows "000000 foo bar".

So this does make the output more consistent with other commands, and
'reset' is a porcelain command, so nobody should be parsing the output
in scripts.

The current behaviour dates back to 0e5a7faa3a ("Make "git reset" a
builtin.", 2007-09-11), so I assume (without digging into the old
codebase too much) that the logic was implemented because there was
no convenience function such as 'pp_commit_easy' that would do this
already.

diff.c: refactor pprint_rename() to use strbufNguyễn Thái Ngọc Duy Thu, 1 Feb 2018 13:02:20 +0000 (20:02 +0700)

diff.c: refactor pprint_rename() to use strbuf

Instead of passing char* around, let function handle strbuf
directly. All callers already use strbuf internally.

This helps kill the "not free" exception in free_diffstat_info(). I
don't think this code is so critical that we need to avoid some free()
calls.

The other benefit comes in the next patch, where we append something
in pname before returning from fill_print_name(). With strbuf, it's
very simple. With "char *" we may have to resort to explicit
reallocation and stuff.

hash: create union for hash context allocationbrian m. carlson Thu, 1 Feb 2018 02:18:38 +0000 (02:18 +0000)

hash: create union for hash context allocation

In various parts of our code, we want to allocate a structure
representing the internal state of a hash algorithm. The original
implementation of the hash algorithm abstraction assumed we would do
that using heap allocations, and added a context size element to struct
git_hash_algo. However, most of the existing code uses stack
allocations and conversion would needlessly complicate various parts of
the code. Add a union for the purpose of allocating hash contexts on
the stack and a typedef for ease of use. Use this union for defining
the init, update, and final functions to avoid casts. Remove the ctxsz
element for struct git_hash_algo, which is no longer very useful.

This does mean that stack allocations will grow slightly as additional
hash functions are added, but this should not be a significant problem,
since we don't allocate many hash contexts. The improved usability and
benefits from avoiding dynamic allocation outweigh this small downside.

This could be done faster by exiting earlier, however by using this

we're not running a lot of them in the TAP output, at the cost of some
overhead.

wildmatch test: create & test files on disk in addition to in-memory

There has never been any full roundtrip testing of what git-ls-files
and other commands that use wildmatch() actually do, rather we've been
satisfied with just testing the underlying C function.

Due to git-ls-files and friends having their own codepaths before they
call wildmatch() there's sometimes differences in the behavior between
the two. Even when we test for those (as with [1]), there was no one
place where you can review how these two modes differ.

Now there is. We now attempt to create a file called $haystack and
match $needle against it for each pair of $needle and $haystack that
we were passing to test-wildmatch.

If we can't create the file we skip the test. This ensures that we can
run this on all platforms and not maintain some infinitely growing
whitelist of e.g. platforms that don't support certain characters in
filenames.

A notable exception to this is Windows, where due to the reasons
explained in [2] the shellscript emulation layer might fake the
creation of a file such as "*", and "test -e" for it will succeed
since it just got created with some character that maps to "*", but
git ls-files won't be fooled by this.

Thus we need to skip creating certain filenames entirely on Windows,
the list here might be overly aggressive. I don't have access to a
Windows system to test this.

As a result of doing these tests we can now see the cases where these
two ways of testing wildmatch differ:

* Creating a file called 'a[]b' and running ls-files 'a[]b' will show
that file, but wildmatch("a[]b", "a[]b") will not match

* wildmatch() won't match a file called \ against \, but ls-files
will.

* `git --glob-pathspecs ls-files 'foo**'` will match a file
'foo/bba/arr', but wildmatch won't, however pathmatch will.

This seems like a bug to me, the two are otherwise equivalent as
these tests show.

This also reveals the case discussed in [1], since 2.16.0 '' is now an
error as far as ls-files is concerned, but wildmatch() itself happily
accepts it.

wildmatch test: perform all tests under all wildmatch() modes

Rewrite the wildmatch() test suite so that each test now tests all
combinations of the wildmatch() WM_CASEFOLD and WM_PATHNAME flags.

Before this change some test inputs were not tested on
e.g. WM_PATHNAME. Now the function is stress tested on all possible
inputs, and for each input we declare what the result should be if the
mode is case-insensitive, or pathname matching, or case-sensitive or
not matching pathnames.

Also before this change, nothing was testing case-insensitive
non-pathname matching, so I've added that to test-wildmatch.c and made
use of it.

This yields a rather scary patch, but there are no functional changes
here, just more test coverage. Some now-redundant tests were deleted
as a result of this change, since they were now duplicating an earlier
test.
