daemon.c: avoid accessing ss_family member of struct sockaddr_storage
When NO_SOCKADDR_STORAGE is set for a platform, either sockaddr_in or
sockaddr_in6 is used intead. Neither of which has an ss_family member.
They have an sin_family and sin6_family member respectively. Since the
addrcmp() function accesses the ss_family member of a sockaddr_storage
struct, compilation fails on platforms which define NO_SOCKADDR_STORAGE.
Since any sockaddr_* structure can be cast to a struct sockaddr and
have its sa_family member read, do so here to workaround this issue.
Thanks to Martin Storsjö for pointing out the fix, and Gary Vaughan
for drawing attention to the issue.

don't use default revision if a rev was specified
If a revision is specified, it happens not to have any commits, don't
use the default revision. By doing so, surprising and undesired

for_each_recent_reflog_ent(): use strbuf, fix offset handling
As Vladimir reported, "git log -g refs/stash" surprisingly showed the reflog
of HEAD if the message in the reflog file was too long. To fix this, convert
for_each_recent_reflog_ent() to use strbuf_getwholeline() instead of fgets(),
for safety and to avoid any size limits for reflog entries.
Also reverse the logic of the part of the function that only looks at file
tails. It used to close the file if fgets() succeeded. The following
fgets() call in the while loop was likely to fail in this case, too, so
passing an offset to for_each_recent_reflog_ent() never worked. Change it to
error out if strbuf_getwholeline() fails instead.

t7406: Fix submodule init config tests
These tests have been broken since they were introduced in commits
ca2cedb (git-submodule: add support for --rebase., 2009-04-24) and
42b4917 (git-submodule: add support for --merge., 2009-06-03).
'git submodule init' expects the submodules to exist in the index.
In this case, the submodules don't exist and therefore looking for
the submodules will always fail. To make matters worse, git submodule
fails visibly to the user by saying:
error: pathspec 'rebasing' did not match any file(s) known to git.
Did you forget to 'git add'?
but doesn't return an error code. This allows the test to fail silently.
Fix it by adding the submodules first.

gitweb: Fix project-specific feature override behavior
This commit fixes a bug in processing project-specific override in
a situation when there is no project, e.g. for the projects list page.
When 'snapshot' feature had project specific config override enabled
by putting
$feature{'snapshot'}{'override'} = 1;
(or equivalent) in $GITWEB_CONFIG, and when viewing toplevel gitweb
page, which means the projects list page (to be more exact this
happens for any project-less action), gitweb would put the following
Perl warnings in error log:
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2065.
fatal: error processing config file(s)
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2221.
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2218.
The problem is in the following fragment of code:
# path to the current git repository
our $git_dir;
$git_dir = "$projectroot/$project" if $project;
# list of supported snapshot formats
our @snapshot_fmts = gitweb_get_feature('snapshot');
@snapshot_fmts = filter_snapshot_fmts(@snapshot_fmts);
For the toplevel gitweb page, which is the list of projects, $project is not
defined, therefore neither is $git_dir. gitweb_get_feature() subroutine
calls git_get_project_config() if project specific override is turned
on... but we don't have project here.
Those errors mentioned above occur in the following fragment of code in
git_get_project_config():
# get config

%config = git_parse_project_config('gitweb');
$config_file = "$git_dir/config";
}
git_parse_project_config() calls git_cmd() which has '--git-dir='.$git_dir
There are (at least) three possible solutions:
1. Harden gitweb_get_feature() so that it doesn't call
git_get_project_config() if $project (and therefore $git_dir) is not
defined; there is no project for project specific config.
2. Harden git_get_project_config() like you did in your fix, returning early
if $git_dir is not defined.
3. Harden git_cmd() so that it doesn't add "--git-dir=$git_dir" if $git_dir
is not defined, and change git_get_project_config() so that it doesn't
even try to access $git_dir if it is not defined.
This commit implements both 1.) and 2.), i.e. gitweb_get_feature() doesn't
call project-specific override if $git_dir is not defined (if there is no
project), and git_get_project_config() returns early if $git_dir is not

This commit fixes a bug in processing project-specific override in
a situation when there is no project, e.g. for the projects list page.
When 'snapshot' feature had project specific config override enabled
by putting
$feature{'snapshot'}{'override'} = 1;
(or equivalent) in $GITWEB_CONFIG, and when viewing toplevel gitweb
page, which means the projects list page (to be more exact this
happens for any project-less action), gitweb would put the following
Perl warnings in error log:
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2065.
fatal: error processing config file(s)
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2221.
gitweb.cgi: Use of uninitialized value $git_dir in concatenation (.) or string at gitweb.cgi line 2218.
The problem is in the following fragment of code:
# path to the current git repository
our $git_dir;
$git_dir = "$projectroot/$project" if $project;
# list of supported snapshot formats
our @snapshot_fmts = gitweb_get_feature('snapshot');
@snapshot_fmts = filter_snapshot_fmts(@snapshot_fmts);
For the toplevel gitweb page, which is the list of projects, $project is not
defined, therefore neither is $git_dir. gitweb_get_feature() subroutine
calls git_get_project_config() if project specific override is turned
on... but we don't have project here.
Those errors mentioned above occur in the following fragment of code in
git_get_project_config():
# get config
if (!defined $config_file ||
$config_file ne "$git_dir/config") {
%config = git_parse_project_config('gitweb');
$config_file = "$git_dir/config";
}
git_parse_project_config() calls git_cmd() which has '--git-dir='.$git_dir

1. Harden gitweb_get_feature() so that it doesn't call

bisect: error out when passing bad path parameters
As reported by Mark Lodato, "git bisect", when it was started with
path parameters that match no commit was kind of working without
taking account of path parameters and was reporting something like:
Bisecting: -1 revisions left to test after this (roughly 0 steps)
It is more correct and safer to just error out in this case, before
displaying the revisions left, so this patch does just that.
Note that this bug is very old, it exists at least since v1.5.5.
And it is possible to detect that case earlier in the bisect
algorithm, but it is not clear that it would be an improvement to
error out earlier, on the contrary it may change the behavior of
"git rev-list --bisect-all" for example, which is currently correct.

fetch --all/--multiple: keep all the fetched branch information
Since "git fetch" learned "--all" and "--multiple" options, it has become
tempting for users to say "git pull --all". Even though it may fetch from
remotes that do not need to be fetched from for merging with the current
branch, it is handy.
"git fetch" however clears the list of fetched branches every time it
contacts a different remote. Unless the current branch is configured to
merge with a branch from a remote that happens to be the last in the list
of remotes that are contacted, "git pull" that fetches from multiple
remotes will not be able to find the branch it should be merging with.
Make "fetch" clear FETCH_HEAD (unless --append is given) and then append
the list of branches fetched to it (even when --append is not given). That
way, "pull" will be able to find the data for the branch being merged in
FETCH_HEAD no matter where the remote appears in the list of remotes to be
contacted by "git fetch".

add-interactive: fix bogus diff header line ordering

first split it into a header and a list of hunks. Some of
the header lines, such as mode changes and deletion, however,
become their own selectable hunks. Later when we reassemble
the patch, we simply concatenate the header and the selected
hunks. This leads to patches like this:
diff --git a/file b/file
index d95f3ad..0000000
--- a/file
+++ /dev/null
deleted file mode 100644
@@ -1 +0,0 @@
-content
Notice how the deletion comes _after_ the ---/+++ lines,
when it should come before.
In many cases, we can get away with this as git-apply
accepts the slightly bogus input. However, in the specific
case of a deletion line that is being applied via "apply
-R", this malformed patch triggers an assert in git-apply.
This comes up when discarding a deletion via "git checkout
-p".
Rather than try to make git-apply accept our odd input,
let's just reassemble the patch in the correct order.

We used to unnecessarily give the read permission to group and others,
regardless of the umask, which isn't serious because the objects are
still protected by their containing directory, but isn't necessary
either.

git_mkstemps_mode: don't set errno to EINVAL on exit.
When reaching the end of git_mkstemps_mode, at least one call to open()
has been done, and errno has been set accordingly. Setting errno is
therefore not necessary, and actually harmfull since callers can't
distinguish e.g. permanent failure from ENOENT, which can just mean that
we need to create the containing directory.

Use git_mkstemp_mode and xmkstemp_mode in odb_mkstemp, not chmod later.
We used to create 0600 files, and then use chmod to set the group and
other permission bits to the umask. This usually has the same effect
as a normal file creation with a umask.
But in the presence of ACLs, the group permission plays the role of
the ACL mask: the "g" bits of newly created files are chosen according
to default ACL mask of the directory, not according to the umask, and
doing a chmod() on these "g" bits affect the ACL's mask instead of
actual group permission.
In other words, creating files with 0600 and then doing a chmod to the
umask creates files which are unreadable by users allowed in the
default ACL. To create the files without breaking ACLs, we let the
umask do it's job at the file's creation time, and get rid of the
later chmod.

git_mkstemp_mode, xmkstemp_mode: variants of gitmkstemps with mode argument.
gitmkstemps emulates the behavior of mkstemps, which is usually used
to create files in a shared directory like /tmp/, hence, it creates
files with permission 0600.
Add git_mkstemps_mode() that allows us to specify the desired mode, and
make git_mkstemps() a wrapper that always uses 0600 to call it. Later we
will use git_mkstemps_mode() when creating pack files.

Add a testcase for ACL with restrictive umask.
Right now, Git creates unreadable pack files on non-shared
repositories when the user has a umask of 077, even when the default
ACLs for the directory would give read/write access to a specific

Loose object files are created world-readable, which doesn't break ACLs,

tests: Fix race condition in t7006-pager
Pagers that do not consume their input are dangerous: for example,
$ GIT_PAGER=: git log
$ echo $?
141
$
The only reason these tests were able to work before was that
'git log' would write to the pipe (and not fill it) before the
pager had time to terminate and close the pipe.
Fix it by using a program that consumes its input, namely wc (as
suggested by Johannes).

sha1_file: be paranoid when creating loose objects
We don't want the data being deflated and stored into loose objects
to be different from what we expect. While the deflated data is
protected by a CRC which is good enough for safe data retrieval
operations, we still want to be doubly sure that the source data used
at object creation time is still what we expected once that data has
been deflated and its CRC32 computed.
The most plausible data corruption may occur if the source file is
modified while Git is deflating and writing it out in a loose object.
Or Git itself could have a bug causing memory corruption. Or even bad
RAM could cause trouble. So it is best to make sure everything is
coherent and checksum protected from beginning to end.
To do so we compute the SHA1 of the data being deflated _after_ the
deflate operation has consumed that data, and make sure it matches
with the expected SHA1. This way we can rely on the CRC32 checked by
the inflate operation to provide a good indication that the data is still
coherent with its SHA1 hash. One pathological case we ignore is when
the data is modified before (or during) deflate call, but changed back
before it is hashed.
There is some overhead of course. Using 'git add' on a set of large files:
Before:
real 0m25.210s
user 0m23.783s
sys 0m1.408s
After:
real 0m26.537s
user 0m25.175s
sys 0m1.358s
The overhead is around 5% for full data coherency guarantee.

sha1_file: don't malloc the whole compressed result when writing out objects
There is no real advantage to malloc the whole output buffer and
deflate the data in a single pass when writing loose objects. That is
like only 1% faster while using more memory, especially with large
files where memory usage is far more. It is best to deflate and write
the data out in small chunks reusing the same memory instead.
For example, using 'git add' on a few large files averaging 40 MB ...
Before:
21.45user 1.10system 0:22.57elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k

t7006-pager: if stdout is not a terminal, make a new one
Testing pagination requires (fake or real) access to a terminal so we
can see whether the pagination automatically kicks in, which makes it
hard to get good coverage when running tests without --verbose. There
are a number of ways to work around that:
- Replace all isatty calls with calls to a custom xisatty wrapper
that usually checks for a terminal but can be overridden for tests.
This would be workable, but it would require implementing xisatty
separately in three languages (C, shell, and perl) and making sure
that any code that is to be tested always uses the wrapper.
- Redirect stdout to /dev/tty. This would be problematic because
there might be no terminal available, and even if a terminal is
available, it might not be appropriate to spew output to it.
- Create a new pseudo-terminal on the fly and capture its output.
This patch implements the third approach.
The new test-terminal.perl helper uses IO::Pty from Expect.pm to create
a terminal and executes the program specified by its arguments with
that terminal as stdout. If the IO::Pty module is missing or not
working on a system, the test script will maintain its old behavior
(skipping most of its tests unless GIT_TEST_OPTS includes --verbose).

cherry_pick_list: quit early if one side is empty
The --cherry-pick logic starts by counting the commits on each side,
so that it can filter away commits on the bigger one. However, so
far it missed an opportunity for optimization: it doesn't need to do
any work if either side is empty.
This in particular helps the common use-case 'git rebase -i HEAD~$n':
it internally uses --cherry-pick, but since HEAD~$n is a direct

tests: Add tests for automatic use of pager
Git’s automatic pagination support has some subtleties. Add some
tests to make sure we don’t break:
- when git will use a pager by default;
- the effect of the --paginate and --no-pager options;
- the effect of pagination on use of color;
- how the choice of pager is configured.
This does not yet test:
- use of pager by scripted commands (git svn and git am);
- effect of the pager.* configuration variables;
- setting of the LESS variable.
Some features involve checking whether stdout is a terminal, so many
of these tests are skipped unless output is passed through to the
terminal (i.e., unless $GIT_TEST_OPTS includes --verbose).
The immediate purpose for these tests was to avoid making things worse
after the breakage from my jn/editor-pager series (see commit 376f39,
2009-11-20). Thanks to Sebastian Celis <sebastian@sebastiancelis.com>
