Add a testcase for ACL with restrictive umask.
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.

Revert "git-svn: always initialize with core.autocrlf=false"
git-svn rebase used to have issues with CRLF conversion. Since these issues
have been fixed, we can safely revert the work-around that disables CRLF
conversion.
Before commit d3c9634e, performing a "git svn rebase" that fetched a
change containing CRLFs corrupted the git-svn meta-data. This was
worked around in d3c9634e by setting core.autocrlf to "false" in the
per-repo config when initing the clone. However, if the config
variable was later changed, the corruption would still occur.
This patch tries to fix it while allowing core.autocrlf to be
enabled, by disabling filters when when hashing.
git-svn is currently the only call-site for hash_and_insert_object
(apart from the test-suite), so changing it should be safe.

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
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
defined.
Add a test for this bug to t/t9500-gitweb-standalone-no-errors.sh test.

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.

The definition of TEST_OBJS in commit daa99a91 (Makefile: make sure
test helpers are rebuilt when headers change, 2010-01-26) moved a use
of $X to before the platform-specific section where it gets defined.
There are at least two ways to fix that:
- Change the definition of TEST_OBJS to use the = delayed
evaluation operator. This way, one need not worry about $(X)
needing to be defined before TEST_OBJS is set.
- Move the definition of TEST_OBJS to below the definition of $X.
Carry out the second. The later site of definition makes the code more
readable, since now a reader only has to look down one line to see what
TEST_OBJS is meant to be used for.
Oddly enough, with or without this change the behavior of the Makefile
is the same. Since TEST_PROGRAMS is defined with delayed evaluation,
the value of
is independent of the value of $X when it is evaluated: the $X in the
pattern and the $X in $(TEST_PROGRAMS) will simply always cancel out.
Make sure $X has the expected expansion anyway to make the code and
the reader’s sanity more robust in the face of future changes.

When svn:mergeinfo contains two new parents in a specific order and
one is ancestor of the other, it is possible that git-svn discards the
wrong one. The first test case ("commit made to merged branch is
reachable from the merge") proves this.
The second test case ("merging two branches in one commit is detected
correctly") is just for completeness, since there was no test for
merging two (feature) branches to trunk in one commit.

move encode_in_pack_object_header() to a better place
Commit 1b22b6c897 made duplicated versions of encode_header() into a
common version called encode_in_pack_object_header(). There is however
a better location that sha1_file.c for such a function though, as
sha1_file.c contains nothing related to the creation of packs, and
it is quite populated already.
Also the comment that was moved to the header file should really remain
near the function as it covers implementation details and provides no
information about the actual function interface.

add-interactive: fix bogus diff header line ordering
When we look at a patch for adding hunks interactively, we
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:
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.

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.

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

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.
