git_connect(): use common return pointTorsten Bögershausen Thu, 28 Nov 2013 19:50:15 +0000 (20:50 +0100)

git_connect(): use common return point

Use only one return point from git_connect(), doing the

return conn;

only at one place in the code.

There may be a little confusion what the variable "host" is for. At
some places it is only the host part, at other places it may include
the port number, so change host into hostandport here.

connect.c: refactor url parsingTorsten Bögershausen Thu, 28 Nov 2013 19:50:03 +0000 (20:50 +0100)

connect.c: refactor url parsing

Make the function is_local() in transport.c public, rename it into
url_is_local_not_ssh() and use it in both transport.c and connect.c

Use a protocol "local" for URLs for the local file system.

One note about using file:// under Windows:

The (absolute) path on Unix like system typically starts with "/".
When the host is empty, it can be omitted, so that a shell scriptlet
url=file://$pwd
will give a URL like "file:///home/user/repo".

Windows does not have the same concept of a root directory located in "/".
When parsing the URL allow "file://C:/user/repo"
(even if RFC1738 indicates that "file:///C:/user/repo" should be used).

git fetch: support host:/~repoTorsten Bögershausen Thu, 28 Nov 2013 19:49:38 +0000 (20:49 +0100)

git fetch: support host:/~repo

The documentation (in urls.txt) says that

"ssh://host:/~repo",
"host:/~repo" or
"host:~repo"

specify the repository "repo" in the home directory at "host".

This has not been working for "host:/~repo".

Before commit 356bec "Support [address] in URLs", the comparison
"url != hostname" could be used to determine if the URL had a scheme
or not: "ssh://host/host" != "host".

However, after 356bec "[::1]" was converted into "::1", yielding
url != hostname as well. To fix this regression, don't use
"if (url != hostname)", but look at the separator instead.

Rename the variable "c" into "separator" to make it easier to read.

git_connect() uses start_command() to invoke the command; consequently,

rev-parse: be more careful with munging argumentsJeff King Fri, 6 Dec 2013 22:07:52 +0000 (17:07 -0500)

rev-parse: be more careful with munging arguments

When rev-parse looks at whether an argument like "foo..bar" or
"foobar^@" is a difference or parent-shorthand, it internally
munges the arguments so that it can pass the individual rev
arguments to get_sha1(). However, we do not consistently un-munge
the result.

For cases where we do not match (e.g., "doesnotexist..HEAD"), we
would then want to try to treat the argument as a filename.
try_difference gets() this right, and always unmunges in this case.
However, try_parent_shorthand() never unmunges, leading to incorrect
error messages, or even incorrect results:

$ git rev-parse foobar^@
foobar
fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

$ >foobar
$ git rev-parse foobar^@
foobar

For cases where we do match, neither function unmunges. This does
not currently matter, since we are done with the argument. However,
a future patch will do further processing, and this prepares for
it. In addition, it's simply a confusing interface for some cases to
modify the const argument, and others not to.

rev-parse: correctly diagnose revision errors before "--"

Rev-parse understands that a "--" may separate revisions and
filenames, and that anything after the "--" is taken as-is.
However, it does not understand that anything before the
token must be a revision (which is the usual rule
implemented by the setup_revisions parser).

Since rev-parse prefers revisions to files when parsing
before the "--", we end up with the correct result (if such
an argument is a revision, we parse it as one, and if it is
not, it is an error either way). However, we misdiagnose
the errors:

$ git rev-parse foobar -- >/dev/null
fatal: ambiguous argument 'foobar': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

$ >foobar
$ git rev-parse foobar -- >/dev/null
fatal: bad flag '--' used after filename

In both cases, we should know that the real error is that
"foobar" is meant to be a revision, but could not be
resolved.

difftool: display the number of files in the diff queue in the prompt

When --prompt option is set, git-difftool displays a prompt for each
modified file to be viewed in an external diff program. At that
point, it could be useful to display a counter and the total number
of files in the diff queue.

Below is the current difftool prompt for the first of 5 modified files:

Viewing: 'diff.c'
Launch 'vimdiff' [Y/n]:

Consider the modified prompt:

Viewing (1/5): 'diff.c'
Launch 'vimdiff' [Y/n]:

The current GIT_EXTERNAL_DIFF mechanism does not tell the number of
paths in the diff queue nor the current counter. To make this
"counter/total" info available for GIT_EXTERNAL_DIFF programs
without breaking existing ones by doing the following:

- Keep track of the number of paths shown so far in diff_options;

- Export two new environment variables from run_external_diff() to
show the total number of paths (from diff_queue_struct) and the
current value of the counter (from diff_options); and

- Update git-difftool--helper to use these two environment variables.

pathspec.c: support adding prefix magic to a pathspec with mnemonic magic

Back in 233c3e6 (parse_pathspec: preserve prefix length via
PATHSPEC_PREFIX_ORIGIN - 2013-07-14), parse_pathspec() is taught to
save prefix length as a dynamic magic. This is needed when the
pathspec is passed to another process and and prefix lenght would be
lost.

Back then we support two cases. If the pathspec is normal, e.g. "abc",
we simply add the prefix to become ":(prefix:2)abc". If the pathspec
contains long magic, e.g. ":(foo,bar)abc" then we turn it to
":(foo,bar,prefix:2)abc". We do not support prefixing on short form,
because the only supported mnemonic '/' disappears after the the
preprocessing steps.

With the introduction of exclude magic with mnemonic '!', we need to
add support for the short form case so that ':!abc' becomes
':(exclude,prefix:2)abc'. Without this, it will break

git-config used a static match array to hold the matches we want to

This in particular fixes the symptoms git-svn had when storing large
numbers of svn-remote.*.added-placeholder entries in the config file.

While the tests are rather more paranoid than just --unset and
--replace-all, the other operations already worked. Indeed git-svn's

pack-objects: name pack files after trailer hashJeff King Thu, 5 Dec 2013 20:28:07 +0000 (15:28 -0500)

pack-objects: name pack files after trailer hash

Our current scheme for naming packfiles is to calculate the
sha1 hash of the sorted list of objects contained in the
packfile. This gives us a unique name, so we are reasonably
sure that two packs with the same name will contain the same
objects.

It does not, however, tell us that two such packs have the
exact same bytes. This makes things awkward if we repack the
same set of objects. Due to run-to-run variations, the bytes
may not be identical (e.g., changed zlib or git versions,
different source object reuse due to new packs in the
repository, or even different deltas due to races during a
multi-threaded delta search).

In theory, this could be helpful to a program that cares
that the packfile contains a certain set of objects, but
does not care about the particular representation. In
practice, no part of git makes use of that, and in many
cases it is potentially harmful. For example, if a dumb http
client fetches the .idx file, it must be sure to get the
exact .pack that matches it. Similarly, a partial transfer
of a .pack file cannot be safely resumed, as the actual
bytes may have changed. This could also affect a local
client which opened the .idx and .pack files, closes the
.pack file (due to memory or file descriptor limits), and
then re-opens a changed packfile.

In all of these cases, git can detect the problem, as we
have the sha1 of the bytes themselves in the pack trailer
(which we verify on transfer), and the .idx file references
the trailer from the matching packfile. But it would be
simpler and more efficient to actually get the correct
bytes, rather than noticing the problem and having to
restart the operation.

This patch simply uses the pack trailer sha1 as the pack
name. It should be similarly unique, but covers the exact
representation of the objects. Other parts of git should not
care, as the pack name is returned by pack-objects and is
essentially opaque.

One test needs to be updated, because it actually corrupts a
pack and expects that re-packing the corrupted bytes will
use the same name. It won't anymore, but we can easily just
use the name that pack-objects hands back.

commit -v: strip diffs and submodule shortlogs from... Jens Lehmann Thu, 5 Dec 2013 19:44:14 +0000 (20:44 +0100)

commit -v: strip diffs and submodule shortlogs from the commit message

When using the '-v' option of "git commit" the diff added to the commit
message temporarily for editing is stripped off after the user exited the
editor by searching for "\ndiff --git " and truncating the commmit message
there if it is found.

But this approach has two problems:

- when the commit message itself contains a line starting with
"diff --git" it will be truncated there prematurely; and

- when the "diff.submodule" setting is set to "log", the diff may
start with "Submodule <hash1>..<hash2>", which will be left in
the commit message while it shouldn't.

Fix that by introducing a special scissor separator line starting with the
comment character ('#' or the core.commentChar config if set) followed by
two lines describing what it is for. The scissor line - which will not be
translated - is used to reliably detect the start of the diff so it can be
chopped off from the commit message, no matter what the user enters there.

replace {pre,suf}fixcmp() with {starts,ends}_with()

Leaving only the function definitions and declarations so that any
new topic in flight can still make use of the old functions, replace
existing uses of the prefixcmp() and suffixcmp() with new API
functions.

The change can be recreated by mechanically applying this:

$ git grep -l -e prefixcmp -e suffixcmp -- \*.c |
grep -v strbuf\\.c |
xargs perl -pi -e '
s|!prefixcmp\(|starts_with\(|g;
s|prefixcmp\(|!starts_with\(|g;
s|!suffixcmp\(|ends_with\(|g;
s|suffixcmp\(|!ends_with\(|g;
'

strbuf: introduce starts_with() and ends_with()Christian Couder Sun, 1 Dec 2013 07:49:16 +0000 (08:49 +0100)

strbuf: introduce starts_with() and ends_with()

prefixcmp() and suffixcmp() share the common "cmp" suffix that
typically are used to name functions that can be used for ordering,
but they can't, because they are not antisymmetric:

prefixcmp("foo", "foobar") < 0
prefixcmp("foobar", "foo") == 0

We in fact do not use these functions for ordering. Replace them
with functions that just check for equality.

Add starts_with() and end_with() that will be used to replace
prefixcmp() and suffixcmp(), respectively, as the first step. These
are named after corresponding functions/methods in programming
languages, like Java, Python and Ruby.

In vcs-svn/fast_export.c, there was already an ends_with() function
that did the same thing. Let's use the new one instead while at it.

builtin/remote: remove postfixcmp() and use suffixcmp... Christian Couder Sun, 1 Dec 2013 07:49:15 +0000 (08:49 +0100)

builtin/remote: remove postfixcmp() and use suffixcmp() instead

Commit 8cc5b290 (git merge -X<option>, 25 Nov 2009) introduced
suffixcmp() with nearly the same implementation as postfixcmp()
that already existed since commit 211c8968 (Make git-remote a
builtin, 29 Feb 2008).

The only difference between the two implementations is that,
when the string is smaller than the suffix, one implementation
returns 1 while the other one returns -1.

But, as postfixcmp() is only used to compare for equality, the
distinction does not matter and does not affect the correctness of
this patch.

As postfixcmp() has always been static in builtin/remote.c
and is used nowhere else, it makes more sense to remove it
and use suffixcmp() instead in builtin/remote.c, rather than
to remove suffixcmp().

environment: normalize use of prefixcmp() by removing " != 0"

To be able to automatically convert prefixcmp() to starts_with()
we need first to make sure that prefixcmp() is always used in
the same way.

So let's remove " != 0" after prefixcmp().

Merge branch 'ak/submodule-foreach-quoting'

A behavior change, but a worthwhile one: "git submodule foreach"
was treating its arguments as part of a single command to be
concatenated and passed to a shell, making writing buggy
scripts too easy.

This patch preserves the old "just pass it to the shell" behavior
when a single argument is passed to 'git submodule foreach' and
moves to a new "skip the shell and use the arguments passed
unmolested" behavior when more than one argument is passed.

The old behavior (always concatenating and passing to the shell)
was similar to the 'ssh' command, while the new behavior (switching
on the number of arguments) is what 'xterm -e' does.

May need more thought to make sure this change is advertised well
so that scripts that used multiple arguments but added their own
extra layer of quoting are not broken.

t5000: simplify gzip prerequisite checksJeff King Tue, 3 Dec 2013 13:21:40 +0000 (08:21 -0500)

t5000: simplify gzip prerequisite checks

In t5000, we test the built-in ".tar.gz" config for
git-archive. To make our tests portable, we check that we
have a way to both gzip and gunzip, and we respected
environment variables to point to alternate commands for
doing these operations.

However, the $GZIP variable did not actually do anything, as
changing it would not affect the baked-in value in
archive-tar.c. Moreover, setting the variable $GZIP
influences gzip itself. From the gzip man page:

The environment variable GZIP can hold a set of default
options for gzip. These options are interpreted first and
can be overwritten by explicit command line parameters.

We could rename this variable, and use it to set up custom
config (or even have a Makefile knob to affect the built
binary), but it is not worth the trouble; nobody has ever
reported a problem with the baked-in default, and they can
always change it via config if they need to. Let's just drop
the variable and use "gzip" in the test (keeping the
prerequisite, of course).

While we're at it, we can drop the GUNZIP variable and
prerequisite; it uses "gzip -d", so if we have GZIP, we
will have both.

We can also use test_lazy_prereq for the gzip prerequisite,
which is simpler and behaves more consistently with the rest
of git (e.g., by making output available when the test is
run with "-v").

gettext.c: detect the vsnprintf bug at runtime

Bug 6530 [1] in glibc causes "git show v0.99.6~1" to fail with error
"your vsnprintf is broken". The workaround avoids that, but it
corrupts system error messages in non-C locales.

The bug has been fixed since 2.17. We could know running glibc version
with gnu_get_libc_version(). But version is not a sure way to detect
the bug because downstream may back port the fix to older versions. Do
a runtime test that immitates the call flow that leads to "your
vsnprintf is broken". Only enable the workaround if the test fails.

Tested on Gentoo Linux, glibc 2.16.0 and 2.17, amd64.

push: also use "upstream" mapping when pushing a single refJunio C Hamano Wed, 4 Dec 2013 00:23:35 +0000 (16:23 -0800)

push: also use "upstream" mapping when pushing a single ref

When the user is using the 'upstream' mode, these commands:

$ git push
$ git push origin

would find the 'upstream' branch for the current branch, and then
push the current branch to update it. However, pushing a single
branch explicitly, i.e.

$ git push origin $(git symbolic-ref --short HEAD)

would not go through the same ref mapping process, and ends up
updating the branch at 'origin' of the same name, which may not
necessarily be the upstream of the branch being pushed.

In the spirit similar to the previous one, map a colon-less refspec
using the upstream mapping logic.

push: use remote.$name.push as a refmapJunio C Hamano Tue, 3 Dec 2013 23:41:15 +0000 (15:41 -0800)

push: use remote.$name.push as a refmap

Since f2690487 (fetch: opportunistically update tracking refs,
2013-05-11), we stopped taking a non-storing refspec given on the
command line of "git fetch" literally, and instead started mapping
it via remote.$name.fetch refspecs. This allows

$ git fetch origin master

from the 'origin' repository, which is configured with

[remote "origin"]
fetch = +refs/heads/*:refs/remotes/origin/*

to update refs/remotes/origin/master with the result, as if the
command line were

$ git fetch origin +master:refs/remotes/origin/master

to reduce surprises and improve usability. Before that change, a
refspec on the command line without a colon was only to fetch the
history and leave the result in FETCH_HEAD, without updating the
remote-tracking branches.

When you are simulating a fetch from you by your mothership with a
push by you into your mothership, instead of having:

[remote "satellite"]
fetch = +refs/heads/*:refs/remotes/satellite/*

on the mothership repository and running:

mothership$ git fetch satellite

you would have:

[remote "mothership"]
push = +refs/heads/*:refs/remotes/satellite/*

on your satellite machine, and run:

satellite$ git push mothership

Because we so far did not make the corresponding change to the push
side, this command:

satellite$ git push mothership master

does _not_ allow you on the satellite to only push 'master' out but
still to the usual destination (i.e. refs/remotes/satellite/master).

Implement the logic to map an unqualified refspec given on the
command line via the remote.$name.push refspec. This will bring a
bit more symmetry between "fetch" and "push".

When --smtp-encryption=ssl, we use a Net::SMTP::SSL connection,
passing its ->new all the options that would otherwise go to
Net::SMTP->new (most options) and IO::Socket::SSL->start_SSL (for the

However, while Net::SMTP::SSL replaces the underlying socket class
with an SSL socket, it does nothing to allow passing options to that
socket. So the SSL-relevant options are lost.

Fortunately there is an escape hatch: we can directly set the options
with IO::Socket::SSL::set_client_defaults. They will then persist
within the IO::Socket::SSL module.

submodule: do not copy unknown update mode from .gitmodules

When submodule.$name.update is given as hint from the upstream in
the .gitmodules file, we used to blindly copy it to .git/config,
unless there already is a value defined for the submodule.

However, there is no reason to expect that the update mode hinted by
the upstream is available in the version of Git the user is using,
and a really custom "!cmd" prepared by an upstream person running on
Linux may not even be available to a user on Windows. It is simply
irresponsible to copy the setting blindly and to attempt to use it
during a later "submodule update" without validating it first.

Just show the suggested value to the diagnostic output, and set the
value to 'none' in the configuration, if it is not one of the ones
that are known to be supported by this version of Git.

commit-slab: sizeof() the right type in xreallocThomas Rast Sun, 1 Dec 2013 20:41:55 +0000 (21:41 +0100)

commit-slab: sizeof() the right type in xrealloc

When allocating the slab, the code accidentally computed the array
size from s->slab (an elemtype**). The slab is an array of elemtype*,
however, so we should take the size of *s->slab.

gitk: Recognize -L option

This gives line-log support to gitk, by exploiting the new support for
processing and showing "inline" diffs straight from the git-log
output.

Note that we 'set allknown 0', which is a bit counterintuitive since
this is a "known" option. But that flag prevents gitk from thinking
it can optimize the view by running rev-list to see the topology; in
the -L case that doesn't work.

gitk: Support showing the gathered inline diffs

The previous commit split the diffs into a separate field. Now we
actually want to show them.

To that end we use the stored diff, and

- process it once to build a fake "tree diff", i.e., a list of all
changed files;

- feed it through parseblobdiffline to actually format it into the
$ctext field, like the existing diff machinery would.

gitk: Split out diff part in $commitinfoThomas Rast Sat, 16 Nov 2013 17:37:42 +0000 (18:37 +0100)

gitk: Split out diff part in $commitinfo

So far we just parsed everything after the headers into the "comment"
bit of $commitinfo, including notes and -- if you gave weird options
-- the diff.

Split out the diff, if any, into a separate field. It's easy to
recognize, since it always starts with /^diff/ and is preceded by an
empty line.

We take care to snip away said empty line. The display code already
properly spaces the end of the message from the first diff, and
leaving another empty line at the end looks ugly.

Documentation: revamp git-cherry(1)Thomas Rast Fri, 22 Nov 2013 16:29:16 +0000 (17:29 +0100)

Documentation: revamp git-cherry(1)

git-cherry(1)'s "description" section has never really managed
to explain to me what the command does. It contains too much
explanation of the algorithm instead of simply saying what
goals it achieves, and too much terminology that we otherwise
do not use (fork-point instead of merge-base).

Try a much more concise approach: state what it finds out, why
this is neat, and how the output is formatted, in a few short
paragraphs. In return, provide much longer examples of how it
fits into a "format-patch | am" based workflow, and how it
compares to reading the same from git-log.

Also carefully avoid using "merge" in a context where it does
not mean something that comes from git-merge(1). Instead, say
"apply" in an attempt to further link to patch workflow
concepts.

While there, also omit the language about _which_ upstream
branch we treat as the default. I literally just learned that
we support having several, so let's not confuse new users
here, especially considering that git-config(1) does not
document this.

commit-slab: declare functions "static inline"

This shuts up compiler warnings about unused functions. No such
warnings are currently triggered, but if someone were to actually
use init_NAME_with_stride() as documented, they would get a warning
about init_NAME() being unused.

While there, write a comment about why the last real declaration of
the variable is without a terminating semicolon, while another
forward declarations have one.

remove #!interpreter line from shell librariesJonathan Nieder Mon, 25 Nov 2013 21:03:52 +0000 (13:03 -0800)

remove #!interpreter line from shell libraries

In a shell snippet meant to be sourced by other shell scripts, an
opening #! line does more harm than good.

The harm:

- When the shell library is sourced, the interpreter and options from
the #! line are not used. Specifying a particular shell can
confuse the reader into thinking it is safe for the shell library
to rely on idiosyncrasies of that shell.

- Using #! instead of a plain comment drops a helpful visual clue
that this is a shell library and not a self-contained script.

- Tools such as lintian can use a #! line to tell when an
installation script has failed by forgetting to set a script
executable. This check does not work if shell libraries also start
with a #! line.

The good:

- Text editors notice the #! line and use it for syntax highlighting
if you try to edit the installed scripts (without ".sh" suffix) in
place.

The use of the #! for file type detection is not needed because Git's
shell libraries are meant to be edited in source form (with ".sh"
suffix). Replace the opening #! lines with comments.

This involves tweaking the test harness's valgrind support to find
shell libraries by looking for "# " in the first line instead of "#!"
(see v1.7.6-rc3~7, 2011-06-17).

Suggested by Russ Allbery through lintian. Thanks to Jeff King and
Clemens Buchacher for further analysis.

Tested by searching for non-executable scripts with #! line:

find . -name .git -prune -o -type f -not -executable |
while read file
do
read line <"$file"
case $line in
'#!'*)
echo "$file"
;;
esac
done

The only remaining scripts found are templates for shell scripts
(unimplemented.sh, wrap-for-bin.sh) and sample input used in tests
(t/t4034/perl/{pre,post}).

test: replace shebangs with descriptions in shell librariesJonathan Nieder Mon, 25 Nov 2013 21:03:06 +0000 (13:03 -0800)

test: replace shebangs with descriptions in shell libraries

A #! line in these files is misleading, since these scriptlets are
meant to be sourced with '.' (using whatever shell sources them)
instead of run directly using the interpreter named on the #! line.

Removing the #! line shouldn't hurt syntax highlighting since
these files have filenames ending with '.sh'. For documentation,
add a brief description of how the files are meant to be used in
place of the shebang line.

contrib: remove git-p4import

The git p4import documentation has suggested git p4 as a better
alternative for more than 6 years. (According to the mailing list
discussion when it was moved to contrib/, git-p4import has serious
bugs --- e.g., its incremental mode just doesn't work.) Since then,
git p4 has been actively developed and was promoted to a standard git
command alongside git svn.

Searches on google.com/trends and stackoverflow suggest that no one is
looking for git-p4import any more. Remove it.

Noticed while considering marking the contrib/p4import/git-p4import.py
script executable as part of a wider sweep.
