fetch-pack: do not check links for partial fetchJonathan Tan Wed, 14 Mar 2018 18:42:41 +0000 (11:42 -0700)

fetch-pack: do not check links for partial fetch

When doing a partial clone or fetch with transfer.fsckobjects=1, use the
--fsck-objects instead of the --strict flag when invoking index-pack so
that links are not checked, only objects. This is because incomplete
links are expected when doing a partial clone or fetch.

index-pack: support checking objects but not links

The index-pack command currently supports the
--check-self-contained-and-connected argument, for internal use only,
that instructs it to only check for broken links and not broken objects.
For partial clones, we need the inverse, so add a --fsck-objects
argument that checks for broken objects and not broken links, also for
internal use only.

This will be used by fetch-pack in a subsequent patch.

t9402-git-cvsserver-refs: don't check the stderr of a subshell

Four 'cvs diff' related tests in 't9402-git-cvsserver-refs.sh' fail
when the test script is run with '-x' tracing (and using a shell other
than a Bash version supporting BASH_XTRACEFD). The reason for those
failures is that the tests check the emptiness of a subshell's stderr,
which includes the trace of commands executed in that subshell as
well, throwing off the emptiness check.

Save the stdout and stderr of the invoked 'cvs' command instead of the
whole subshell, so the latter remains free from tracing output. (Note
that changing how stdout is saved is only done for the sake of
consistency, it's not necessary for correctness.)

After this change t9402 passes with '-x', even when running with
/bin/sh.

t9400-git-cvsserver-server: don't rely on the output of 'test_cmp'

The test 'cvs update (-p)' redirects and checks 'test_cmp's stdout and
even its stderr. The commit introducing this test in 6e8937a084
(cvsserver: Add test for update -p, 2008-03-27) doesn't discuss why,
in fact its log message only consists of that subject line. Anyway,
weird as it is, it kind of made sense due to the way that test was
structured:

After a bit of preparation, this test updates four files via CVS and
checks their contents using 'test_cmp', but it does so in a for loop
iterating over the names of those four files. Now, the exit status of
a for loop is the exit status of the last command executed in the
loop, meaning that the test can't simply rely on the exit code of
'test_cmp' in the loop's body. Instead, the test works it around by
relying on the stdout of 'test_cmp' being silent on success and
showing the diff on failure, as it appends the stdout of all four
'test_cmp' invocations to a single file and checks that file's
emptiness after the loop (with 'test -z "$(cat ...)"', no less; there
was no 'test_must_be_empty' back then). Furthermore, the test
redirects the stderr of those 'test_cmp' invocations to this file,
too: while 'test_cmp' itself doesn't output anything to stderr, the
invoked 'diff' or 'cmp' commands do send their error messages there,
e.g. if they can't open a file because its name was misspelled.

This also makes this test fail when the test script is run with '-x'
tracing (and using a shell other than a Bash version supporting
BASH_XTRACEFD), because 'test_cmp's stderr contains the trace of the
'diff' command executed inside the helper function, throwing off the
subsequent emptiness check.

Stop relying on 'test_cmp's output and instead run 'test_cmp a b ||
return 1' in the for loop in order to make 'test_cmp's error code fail
the test. Furthermore, add the missing && after the cvs command to
create a && chain in the loop's body.

After this change t9400 passes with '-x', even when running with
/bin/sh.

Merge branch 'jc/allow-ff-merging-kept-tags'

Since Git 1.7.9, "git merge" defaulted to --no-ff (i.e. even when
the side branch being merged is a descendant of the current commit,
create a merge commit instead of fast-forwarding) when merging a
tag object. This was appropriate default for integrators who pull
signed tags from their downstream contributors, but caused an
unnecessary merges when used by downstream contributors who
habitually "catch up" their topic branches with tagged releases
from the upstream. Update "git merge" to default to --no-ff only
when merging a tag object that does *not* sit at its usual place in
refs/tags/ hierarchy, and allow fast-forwarding otherwise, to
mitigate the problem.

perl Git::LoadCPAN: emit better errors under NO_PERL_CP... Ævar Arnfjörð Bjarmason Sat, 3 Mar 2018 15:38:17 +0000 (15:38 +0000)

perl Git::LoadCPAN: emit better errors under NO_PERL_CPAN_FALLBACKS

Before my 20d2a30f8f ("Makefile: replace perl/Makefile.PL with simple
make rules", 2017-12-10) on an OS package that removed the
private-Error.pm copy we carried around manually removing the OS's
Error.pm would yield:

$ git add -p
Can't locate Error.pm in @INC (you may need to install the Error module) [...]

Now, before this change we'll instead emit this more cryptic error:

$ git add -p
BUG: '/usr/share/perl5/Git/FromCPAN' should be a directory! at /usr/share/perl5/Git/Error.pm line 36.

This is a confusing error. Now if the new NO_PERL_CPAN_FALLBACKS
option is specified and we can't find the module we'll instead emit:

$ /tmp/git/bin/git add -p
BUG: The 'Error' module is not here, but NO_PERL_CPAN_FALLBACKS was set!

[...]

Where [...] is the lengthy explanation seen in the change below, which
explains what the potential breakage is, and how to fix it.

The reason for checking @@NO_PERL_CPAN_FALLBACKS@@] against the empty
string in Perl is as opposed to checking for a boolean value is that
that's (as far as I can tell) make's idea of a string that's set, and
e.g. NO_PERL_CPAN_FALLBACKS=0 is enough to set NO_PERL_CPAN_FALLBACKS.

We include some perl modules which are not part of the core perl

our perl-based tools and scripts without requiring users to install the
modules from CPAN or their operating system packages.

Users whose operating system provides these modules and packagers of Git
often don't want to ship or use these bundled modules. Allow these
users to set NO_PERL_CPAN_FALLBACKS to avoid installing the bundled

perl: generalize the Git::LoadCPAN facility

Change the two wrappers that load from CPAN (local OS) or our own copy
to do so via the same codepath.

I added the Error.pm wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10), and shortly
afterwards Matthieu Moy added a wrapper for Mail::Address in
bd869f67b9 ("send-email: add and use a local copy of Mail::Address",
2018-01-05).

His loader was simpler since Mail::Address doesn't have an "import"
method, but didn't do the same sanity checking; For example, a missing
FromCPAN directory (which OS packages are likely not to have) wouldn't
be explicitly warned about as a "BUG: ...".

Update both to use a common implementation based on the previous
Error.pm loader. Which has been amended to take the module to load as
parameter, as well as whether or not that module has an import
method.

This loader should be generic enough to handle almost all CPAN modules
out there, some use some crazy loading magic and wouldn't like being
wrapped like this, but that would be immediately obvious, and we'd
find out right away since the module wouldn't work at all.

perl: move CPAN loader wrappers to another namespace

Move the Git::Error and Git::Mail::Address wrappers to the
Git::LoadCPAN::Loader::* namespace, e.g. Git::LoadCPAN::Error. That
module will then either load Error from CPAN (if installed on the OS),
or use Git::FromCPAN::Error.

When I added the Error wrapper in 20d2a30f8f ("Makefile: replace
perl/Makefile.PL with simple make rules", 2017-12-10) I didn't think
about how confusing it would be to have these modules sitting in the
same tree as our normal modules. Let's put these all into
Git::{Load,From}CPAN::* to clearly distinguish them from the rest.

This also makes things a bit less confusing since there was already a
Git::Error namespace ever since 8b9150e3e3 ("Git.pm: Handle failed

perl: update our ancient copy of Error.pm

The Error.pm shipped with Git as a fallback if there was no Error.pm
on the system was released in April 2006. There's been dozens of
releases since then, the latest at August 7, 2017. Let's update to
that.

I don't know of anything we need from this new release or which this
fixes. This change is simply a matter of keeping up with
upstream. Before this users who'd install git via their package system
would get an up-to-date Error.pm, but if it's installed from source
they'd get one more than a decade old.

This undoes a local hack we'd accumulated in 96bc4de85c ("Eliminate
Scalar::Util usage from private-Error.pm", 2006-07-26), it's been
redundant since my d48b284183 ("perl: bump the required Perl version
to 5.8 from 5.6.[21]", 2010-09-24).

This also undoes 3a51467b94 ("Typo fix: replacing it's -> its",
2013-04-13). This is the Nth time I find that some upstream code of
ours (in contrib/, in sha1dc/ and now in perl/ ...) has diverged from
upstream because of some tree-wide typo fixing. Let's not do those
fixes against upstream projects, it's more valuable that we have a 1=1
mapping to upstream than to fix typos in docs we never even generate
from this code. If someone wants to fix typos in them fine, but they
should do it with a patch to upstream which git.git can then
incorporate.

The upstream code doesn't cleanly pass a --check, so I'm adding a
.gitattributes file for similar reasons as done for sha1dc in
5d184f468e ("sha1dc: ignore indent-with-non-tab whitespace
violations", 2017-06-06).

git-send-email: unconditionally use Net::{SMTP,Domain}

The Net::SMTP and Net::Domain were both first released with perl
v5.7.3[1], since my d48b284183 ("perl: bump the required Perl version
to 5.8 from 5.6.[21]", 2010-09-24) we've depended on 5.8, so there's
no reason to conditionally require them anymore.

This conditional loading was initially added in
87840620fd ("send-email: only 'require' instead of 'use' Net::SMTP",
2006-06-01) for Net::SMTP and 134550fe21 ("git-send-email.perl - try
to give real name of the calling host to HELO/EHLO", 2010-03-14) for
Net::Domain, both of which predate the hard dependency on 5.8.

Since they're guaranteed to be installed now let's "use" them
instead. The cost of loading them both is trivial given what
git-send-email does (~15ms on my system), and it's better to not defer
any potential loading errors until runtime.

This patch is better viewed with -w, which shows that the only change
in the last two hunks is removing the "if eval" wrapper block.

add -p: calculate offset delta for edited patchesPhillip Wood Mon, 5 Mar 2018 10:56:28 +0000 (10:56 +0000)

add -p: calculate offset delta for edited patches

Recount the number of preimage and postimage lines in a hunk after it
has been edited so any change in the number of insertions or deletions
can be used to adjust the offsets of subsequent hunks. If an edited
hunk is subsequently split then the offset correction will be lost. It
would be possible to fix this if it is a problem, however the code
here is still an improvement on the status quo for the common case
where an edited hunk is applied without being split.

This is also a necessary step to removing '--recount' and
'--allow-overlap' from the invocation of 'git apply'. Before
'--recount' can be removed the splitting and coalescing counting needs
to be fixed to handle a missing newline at the end of a file. In order
to remove '--allow-overlap' there needs to be i) some way of verifying
the offset data in the edited hunk (probably by correlating the
preimage (or postimage if the patch is going to be applied in reverse)
lines of the edited and unedited versions to see if they are offset or
if any leading/trailing context lines have been removed) and ii) a way of
dealing with edited hunks that change context lines that are shared
with neighbouring hunks.

userdiff: add built-in pattern for golangAlban Gruin Thu, 1 Mar 2018 11:19:07 +0000 (12:19 +0100)

userdiff: add built-in pattern for golang

This adds xfuncname and word_regex patterns for golang, a quite
popular programming language. It also includes test cases for the
xfuncname regex (t4018) and updated documentation.

The xfuncname regex finds functions, structs and interfaces. Although
the Go language prohibits the opening brace from being on its own
line, the regex does not makes it mandatory, to be able to match
`func` statements like this:

func foo(bar int,
baz int) {
}

This is covered by the test case t4018/golang-long-func.

The word_regex pattern finds identifiers, integers, floats, complex
numbers and operators, according to the go specification.

write_locked_index(): add flag to avoid writing unchang... Martin Ågren Thu, 1 Mar 2018 20:40:20 +0000 (21:40 +0100)

write_locked_index(): add flag to avoid writing unchanged index

We have several callers like

if (active_cache_changed && write_locked_index(...))
handle_error();
rollback_lock_file(...);

where the final rollback is needed because "!active_cache_changed"
shortcuts the if-expression. There are also a few variants of this,
including some if-else constructs that make it more clear when the
explicit rollback is really needed.

Teach `write_locked_index()` to take a new flag SKIP_IF_UNCHANGED and
simplify the callers. Leave the most complicated of the callers (in
builtin/update-index.c) unchanged. Rewriting it to use this new flag
would end up duplicating logic.

We could have made the new flag behave the other way round
("FORCE_WRITE"), but that could break existing users behind their backs.
Let's take the more conservative approach. We can still migrate existing
callers to use our new flag. Later we might even be able to flip the
default, possibly without entirely ignoring the risk to in-flight or
out-of-tree topics.

add -p: adjust offsets of subsequent hunks when one is skipped

Since commit 8cbd431082 ("git-add--interactive: replace hunk
recounting with apply --recount", 2008-7-2) if a hunk is skipped then
we rely on the context lines to apply subsequent hunks in the right
place. While this works most of the time it is possible for hunks to
end up being applied in the wrong place. To fix this adjust the offset
of subsequent hunks to correct for any change in the number of
insertions or deletions due to the skipped hunk. The change in offset
due to edited hunks that have the number of insertions or deletions
changed is ignored here, it will be fixed in the next commit.

t3701: add failing test for pathological context lines

When a hunk is skipped by add -i the offsets of subsequent hunks are
not adjusted to account for any missing insertions due to the skipped
hunk. Most of the time this does not matter as apply uses the context
lines to apply the subsequent hunks in the correct place, however in
pathological cases the context lines will match at the now incorrect
offset and the hunk will be applied in the wrong place. The offsets of
hunks following an edited hunk that has had the number of insertions
or deletions changed also need to be updated in the same way. Add
failing tests to demonstrate this.

t3701: don't hard code sha1 hash values

Use a filter when comparing diffs to fix the value of non-zero hashes
in diff index lines so we're not hard coding sha1 hash values in the
expected output. This makes it easier to change the expected output if
a test is edited as we don't need to worry about the exact hash value
and means the tests will work when the hash algorithm is transitioned
away from sha1.

commit: run git gc --auto just before the post-commit... Ævar Arnfjörð Bjarmason Wed, 28 Feb 2018 23:04:25 +0000 (23:04 +0000)

commit: run git gc --auto just before the post-commit hook

Change the behavior of git-commit back to what it was back in
d4bb43ee27 ("Invoke "git gc --auto" from commit, merge, am and
rebase.", 2007-09-05) when it was git-commit.sh.

Shortly afterwards in f5bbc3225c ("Port git commit to C.", 2007-11-08)
when it was ported to C, the "git gc --auto" invocation went away.

Since that unintended regression, git gc --auto only ran for git-am,
git-merge, git-fetch, and git-receive-pack. It was possible to
write a script that would "git commit" a lot of data locally, and gc
would never run.

One such repository that was locally committing generated zone file
changes had grown to a size of ~60GB before a daily cronjob was added
to "git gc", bringing it down to less than 1GB. This will make such
cases work without intervention.

I think fixing such pathological cases where the repository will grow
forever is a worthwhile trade-off for spending a couple of
milliseconds calling "git gc --auto" (in the common cases where it
doesn't do anything).

hooks/pre-auto-gc-battery: allow gc to run on non-laptops

Desktops and servers tend to have no power sensor, thus on_ac_power returns
255 ("unknown"). Thus, let's take any answer other than 1 ("battery") as
no contraindication to run gc.

If that tool returns "unknown", there's no point in querying other sources
as it already queried them, and is smarter than us (can handle multiple
adapters).

untracked cache: use git_env_bool() not getenv() for customization

GIT_DISABLE_UNTRACKED_CACHE and GIT_TEST_UNTRACKED_CACHE are only
sensed for their presense by using getenv(); use git_env_bool()
instead so that GIT_DISABLE_UNTRACKED_CACHE=false would work as
naïvely expected.

Also rename GIT_TEST_UNTRACKED_CACHE to GIT_FORCE_UNTRACKED_CACHE
to express what it does more honestly. Forcing its use may be one
useful thing to do while testing the feature, but testing does not
have to be the only use of the knob.

While at it, avoid repeated calls to git_env_bool() by capturing the
return value from the first call in a static variable.
