Steffen Prohaska 2de9de5e4a Move code interpreting path relative to exec-dir to new function system_path()
Expanding system paths relative to git_exec_path can be used for
creating an installation that can be moved to a different directory
without re-compiling.  We use this approach for template_dir and the
system wide gitconfig.  The Windows installer (msysgit) is an example
for such a setup.

This commit moves common code to a new function system_path().  System
paths that are to be interpreted relative to git_exec_path are passed to
system_path() and the return value is used instead of the original path.
system_path() prefixes a relative path with git_exec_path and leaves
absolute paths unmodified.  For example, we now write

    template_dir = system_path(DEFAULT_GIT_TEMPLATE_DIR);

[j6t: moved from path.c to exec_cmd.c]

Sverre Hvammen Johansen 3d1dd4728b reduce_heads(): thinkofix
When comparing two commit objects for equality, it is sufficient to
compare their in-core pointers because the object layer guarantees the
uniqueness.  However, comparing pointers to two "struct commit_list"
instances that point at the same commit does not make any sense.

Spotted by Sverre Hvammen Johansen who wrote an additional test to expose
the problem, fixed by Miklos Vajna.

Alexander N. Gavrilov fce87ae538 Fix quadratic performance in rewrite_one.
Parent commits are usually older than their children. Thus,
on each iteration of the loop in rewrite_one, add_parents_to_list
traverses all commits previously processed by the loop.
It performs very poorly in case of very long rewrite chains.

Shawn O. Pearce ab02dfe533 bash completion: Improve responsiveness of git-log completion
Junio noticed the bash completion has been taking a long time lately.
Petr Baudis tracked it down to 72e5e989b ("bash: Add space after
unique command name is completed.").  Tracing the code showed
we spent significant time inside of this loop within __gitcomp,
due to the string copying overhead.

  [28.146109654] _git common over
  [28.164791148] gitrefs in
  [28.280302268] gitrefs dir out
  [28.300939737] gitcomp in
  [28.308378112] gitcomp pre-case
* [28.313407453] gitcomp iter in
* [28.701270296] gitcomp iter out
  [28.713370786] out normal

Since __git_refs avoids this string copying by forking and using
echo we use the same trick here when we need to finish generating
the names for the caller.

Johannes Schindelin 0af0ac7ebb Move MERGE_RR from .git/rr-cache/ into .git/
If you want to reuse the rerere cache in another repository, and set
a symbolic link to it, you do not want to have the two repositories
interfer with each other by accessing the _same_ MERGE_RR.

For example, if you use contrib/git-new-workdir to set up a second
working directory, and you have a conflict in one working directory,
but commit in the other working directory first, the wrong "resolution"
will be recorded.

The easy solution is to move MERGE_RR out of the rr-cache/ directory,
which also corresponds with the notion that rr-cache/ contains cached
resolutions, not some intermediate temporary states.

Noticed by Kalle Olavi Niemitalo.

Junio C Hamano 329636b435 t0004: fix timing bug
The test created an initial commit, made .git/objects unwritable and then
exercised various codepaths to create loose commit, tree and blob objects
to make sure the commands notice failures from these attempts.

However, the initial commit was not preceded with test_tick, which made
its object name depend on the timestamp.  The names of all the later tree
and blob objects the test tried to create were static.  If the initial
commit's object name happened to begin with the same two hexdigits as the
tree or blob objects the test later attempted to create, the fan-out
directory in which these tree or blob would be created is already created
when the initial commit was made, and the object creation succeeds, and
commands being tested should not notice any failure --- in short, the test
was bogus.

This makes the fan-out directories also unwritable, and adds test_tick
before the commit object creation to make the test repeatable.

The contents of the file to create a blob from "a" to "60" is to force the
name of the blob object to begin with "1b", which shares the fan-out
directory with the initial commit that is created with the test.  This was
useful when diagnosing the breakage of this test.

Johannes Schindelin c4adea82c5 Convert CR/LF to LF in tag signatures
On Windows, gpg outputs CR/LF signatures.  But since the tag messages
are already stripped of the CR by stripspace(), it is arguably nicer
to do the same for the tag signature.  Actually, this patch does not
look for CR/LF, but strips all CRs from the signature.  It does so not
only on Windows but on all platforms to keep the code simpler.

Petr Baudis 8c6202d869 Fix backwards-incompatible handling of core.sharedRepository
06cbe85 (Make core.sharedRepository more generic, 2008-04-16) broke the
traditional setting of core.sharedRepository to true, which was to make
the repository group writable: with umask 022, it would clear the
permission bits for 'other'. (umask 002 did not exhibit this behaviour
since pre-chmod() check in adjust_shared_perm() fails in that case.)

The call to adjust_shared_perm() should only loosen the permission.
If the user has umask like 022 or 002 that allow others to read, the
resulting files should be made readable and writable by group, without
restricting the readability by others.

This patch fixes the adjust_shared_perm() mode tweak based on Junio's
suggestion and adds the appropriate tests to t/t1301-shared-repo.sh.

Olivier Marin 99d698f1e7 builtin-rerere: more carefully find conflict markers
When a conflicting file contains a line that begin with "=======", rerere
failed to parse conflict markers. This result to a wrong preimage file and
an unexpected error for the user.  The boundary between ours and theirs
not just begin with 7 equals, but is followed by either a SP or a LF.

This patch enforces parsing rules so that markers match in the right order,
and when ambiguous, the command does not autoresolve the conflicted file.

Especially because we are introducing rerere.autoupdate configuration
(which is off by default for safety) that automatically stages the
resolution made by rerere, it is necessary to make sure that we do not
autoresolve when there is any ambiguity.

Junio C Hamano a9a3e82e6d apply: fix copy/rename breakage
7ebd52a (Merge branch 'dz/apply-again', 2008-07-01) taught "git-apply" to
grok a (non-git) patch that is a concatenation of separate patches that
touch the same file number of times, by recording the postimage of patch
application of previous round and using it as the preimage for later
rounds.

This "incremental" mode of patch application fundamentally contradicts
with the way git rename/copy patches are designed.  When a git patch talks
about a file A getting modified, and a new file B created out of A, like
this:

	diff --git a/A b/A
	--- a/A
	+++ b/A
	... change text here ...
	diff --git a/A b/B
	copy from A
	copy to B
	--- a/A
	+++ b/B
	... change text here ...

the second change to produce B does not depend on what is done to A with
the first change in any way.  This is explicitly done so for reviewability
of individual patches.

With this commit, we do not look at 'fn_table' that records the postimage
of previous round when applying a patch to produce a new file out of an
existing file.

Shawn O. Pearce eac12e2d4d Correct pack memory leak causing git gc to try to exceed ulimit
When recursing to unpack a delta base we must unuse_pack() so that
the pack window for the current object does not remain pinned in
memory while the delta base is itself being unpacked and materialized
for our use.

On a long delta chain of 50 objects we may need to access 6 different
windows from a very large (>3G) pack file in order to obtain all
of the delta base content.  If the process ulimit permits us to
map/allocate only 1.5G we must release windows during this recursion
to ensure we stay within the ulimit and transition memory from pack
cache to standard malloc, or other mmap needs.

Inserting an unuse_pack() call prior to the recursion allows us to
avoid pinning the current window, making it available for garbage
collection if memory runs low.

This has been broken since at least before 1.5.1-rc1, and very
likely earlier than that.  Its fixed now.  :)

SZEDER Gábor d773c6314d bash: offer only paths after '--'
Many git commands use '--' to separate subcommands, options, and refs
from paths.  However, the programmable completion for several of these
commands does not respect the '--', and offer subcommands, options, or
refs after a '--', although only paths are permitted.  e.g. 'git bisect
-- <TAB>' offers subcommands, 'git log -- --<TAB>' offers options and
'git log -- git<TAB>' offers all gitgui tags.

The completion for the following commands share this wrong behaviour:
  am add bisect commit diff log reset shortlog submodule gitk.

To avoid this, we check the presence of a '--' on the command line first
and let the shell do filename completion, if one is found.

This step merely moves the parser to an incremental version, still using
parse_revisions.
