sha1_file.c: Don't retain open fds on small packs
If a pack file is small enough that its entire contents fits within
one mmap window, mmap the file and then immediately close its file
descriptor. This reduces the number of file descriptors that are
needed to read from repositories with many tiny pack files, such
as one that has received 1000 pushes (and created 1000 small pack
files) since its last repack.

Limit file descriptors used by packs
Rather than using 'errno == EMFILE' after a failed open() call
to indicate the process is out of file descriptors and an LRU
pack window should be closed, place a hard upper limit on the
number of open packs based on the actual rlimit of the process.
By using a hard upper limit that is below the rlimit of the current
process it is not necessary to check for EMFILE on every single
fd-allocating system call. Instead reserving 25 file descriptors
makes it safe to assume the system call won't fail due to being over
the filedescriptor limit. Here 25 is chosen as a WAG, but considers
3 for stdin/stdout/stderr, and at least a few for other Git code
to operate on temporary files. An additional 20 is reserved as it
is not known what the C library needs to perform other services on
Git's behalf, such as nsswitch or name resolution.
This fixes a case where running `git gc --auto` in a repository
with more than 1024 packs (but an rlimit of 1024 open fds) fails
due to the temporary output file not being able to allocate a
file descriptor. The output file is opened by pack-objects after
object enumeration and delta compression are done, both of which
have already opened all of the packs and fully populated the file
descriptor table.

index-pack --verify: read anomalous offsets from v2 idx file
A pack v2 .idx file usually records offset using 64-bit representation
only when the offset does not fit within 31-bit, but you can handcraft
your .idx file to record smaller offset using 64-bit, storing all zero
in the upper 4-byte. By inspecting the original idx file when running
index-pack --verify, encode such low offsets that do not need to be in
64-bit but are encoded using 64-bit just like the original idx file so
that we can still validate the pack/idx pair by comparing the idx file
recomputed with the original.

index-pack: --verify
Given an existing .pack file and the .idx file that describes it,
this new mode of operation reads and re-index the packfile and makes
sure the existing .idx file matches the result byte-for-byte.
All the objects in the .pack file are validated during this operation as
well. Unlike verify-pack, which visits each object described in the .idx
file in the SHA-1 order, index-pack efficiently exploits the delta-chain
to avoid rebuilding the objects that are used as the base of deltified
objects over and over again while validating the objects, resulting in
much quicker verification of the .pack file and its .idx file.
This version however cannot verify a .pack/.idx pair with a handcrafted v2
index that uses 64-bit offset representation for offsets that would fit
within 31-bit. You can create such an .idx file by giving a custom offset
to --index-version option to the command.

index-pack: group the delta-base array entries also by type
Entries in the delta_base array are only grouped by the bytepattern in
the delta_base union, some of which have 20-byte object name of the base
object (i.e. base for REF_DELTA objects), while others have sizeof(off_t)
bytes followed by enough NULs to fill 20-byte. The loops to iterate
through a range inside this array still needs to inspect the type of the
delta, and skip over false hits.
Group the entries also by type to eliminate the potential of false hits.

vcs-svn: teach line_buffer about temporary files
It can sometimes be useful to write information temporarily to file,
to read back later. These functions allow a program to use the
line_buffer facilities when doing so.
It works like this:
1. find a unique filename with buffer_tmpfile_init.
2. rewind with buffer_tmpfile_rewind. This returns a stdio
handle for writing.
3. when finished writing, declare so with
buffer_tmpfile_prepare_to_read. The return value indicates
how many bytes were written.
4. read whatever portion of the file is needed.
5. if finished, remove the temporary file with buffer_deinit.
otherwise, go back to step 2,
The svn support would use this to buffer the postimage from delta
application until the length is known and fast-import can receive
the resulting blob.

buffer_read_char can be used in place of buffer_read_string(1) to
avoid consuming valuable static buffer space. The delta applier will
use this to read variable-length integers one byte at a time.
Underneath, it is fgetc, wrapped so the line_buffer library can

most line_buffer functions are not thread-safe anyway.

vcs-svn: add binary-safe read function
buffer_read_string works well for non line-oriented input except for
one problem: it does not tell the caller how many bytes were actually
written. This means that unless one is very careful about checking
for errors (and eof) the calling program cannot tell the difference
between the string "foo" followed by an early end of file and the
string "foo\0bar\0baz".
So introduce a variant that reports the length, too, a thinner wrapper
around strbuf_fread. Its result is written to a strbuf so the caller
does not need to keep track of the number of bytes read.

t0081 (line-buffer): add buffering tests
POSIX makes the behavior of read(2) from a pipe fairly clear: a read
from an empty pipe will block until there is data available and any
other read will not block, prefering to return a partial result.
Likewise, fread(3) and fgets(3) are clearly specified to act as
though implemented by calling fgetc(3) in a simple loop. But the
buffering behavior of fgetc is less clear.
Luckily, no sane platform is going to implement fgetc by calling the
equivalent of read(2) more than once. fgetc has to be able to
return without filling its buffer to preserve errno when errors are
encountered anyway. So let's assume the simpler behavior (trust) but
add some tests to catch insane platforms that violate that when they
come (verify).
First check that fread can handle a 0-length read from an empty fifo.
Because open(O_RDONLY) blocks until the writing end is open, open the
writing end of the fifo in advance in a subshell.
Next try short inputs from a pipe that is not filled all the way.
Lastly (two tests) try very large inputs from a pipe that will not fit
in the relevant buffers. The first of these tests reads a little
more than 8192 bytes, which is BUFSIZ (the size of stdio's buffers)
on this Linux machine. The second reads a little over 64 KiB (the
pipe capacity on Linux) and is not run unless requested by setting
the GIT_REMOTE_SVN_TEST_BIG_FILES environment variable.

vcs-svn: teach line_buffer to handle multiple input files
Collect the line_buffer state in a newly public line_buffer struct.
Callers can use multiple line_buffers to manage input from multiple
files at a time.
svn-fe's delta applier will use this to stream a delta from svnrdump
and the preimage it applies to from fast-import at the same time.
The tests don't take advantage of the new features, but I think that's
okay. It is easier to find lingering examples of nonreentrant code by
searching for "static" in line_buffer.c.

fast-import: add 'ls' command
Lazy fast-import frontend authors that want to rely on the backend to
keep track of the content of the imported trees _almost_ have what
they need in the 'cat-blob' command (v1.7.4-rc0~30^2~3, 2010-11-28).
But it is not quite enough, since
(1) cat-blob can be used to retrieve the content of files, but
not their mode, and
(2) using cat-blob requires the frontend to keep track of a name
(mark number or object id) for each blob to be retrieved
Introduce an 'ls' command to complement cat-blob and take care of the
remaining needs. The 'ls' command finds what is at a given path
within a given tree-ish (tag, commit, or tree):
'ls' SP <dataref> SP <path> LF
or in fast-import's active commit:
'ls' SP <path> LF
The response is a single line sent through the cat-blob channel,
imitating ls-tree output. So for example:
FE> ls :1 Documentation
gfi> 040000 tree 9e6c2b599341d28a2a375f8207507e0a2a627fe9 Documentation
FE> ls 9e6c2b599341d28a2a375f8207507e0a2a627fe9 git-fast-import.txt
gfi> 100644 blob 4f92954396e3f0f97e75b6838a5635b583708870 git-fast-import.txt
FE> ls :1 RelNotes
gfi> 120000 blob b942e499449d97aeb50c73ca2bdc1c6e6d528743 RelNotes
FE> cat-blob b942e499449d97aeb50c73ca2bdc1c6e6d528743
gfi> b942e499449d97aeb50c73ca2bdc1c6e6d528743 blob 32
gfi> Documentation/RelNotes/1.7.4.txt
The most interesting parts of the reply are the first word, which is
a 6-digit octal mode (regular file, executable, symlink, directory,
or submodule), and the part from the second space to the tab, which is
a <dataref> that can be used in later cat-blob, ls, and filemodify (M)
commands to refer to the content (blob, tree, or commit) at that path.
If there is nothing there, the response is "missing some/path".
The intent is for this command to be used to read files from the
active commit, so a frontend can apply patches to them, and to copy
files and directories from previous revisions.
For example, proposed updates to svn-fe use this command in place of
its internal representation of the repository directory structure.
This simplifies the frontend a great deal and means support for
resuming an import in a separate fast-import run (i.e., incremental
import) is basically free.

vcs-svn: replace buffer_read_string memory pool with a strbuf
obj_pool is inherently global and does not use the standard growing
factor alloc_nr, which makes it feel out of place in the git codebase.
Plus it is overkill for this application: all that is needed is a
buffer that can grow between requests to accomodate larger strings.
Use a strbuf instead.
As a side effect, this improves the error handling: allocation
failures will result in a clean exit instead of segfaults. It would
be nice to add a test case (using ulimit or failmalloc) but that can
wait for another day.

files in various points in the history or build older versions of the
software, without recording any new commit, and come back to an existing
branch. When used in this "sightseer" mode, detached HEAD is a perfectly
safe mechanism. It also is a useful state to experiment with throw-away
commits.
When coming back to an existing branch with "git checkout master",
however, the commits that were created on the detached HEAD will become
unreachable from anywhere but the reflog of the HEAD. Check if the commit
we are about to leave is connected to some ref, and give a final warning
otherwise to remind the user for safety.

format-patch: wrap long header lines
Subject and identity headers may be arbitrarily long. In the
past, we just assumed that single-line headers would be
reasonably short. For multi-line subjects that we squish
into a single line, we just "pre-folded" the data in
pp_title_line by adding a newline and indentation.
There were two problems. One is that, although rare,
single-line messages can actually be longer than the
recommended line-length limits. The second is that the
pre-folding interacted badly with rfc2047 encoding, leading
to malformed headers.
Instead, let's stop pre-folding the subject lines, and just
fold everything based on length in add_rfc2047, whether
it is encoded or not.

strbuf: add fixed-length version of add_wrapped_text
The function strbuf_add_wrapped_text takes a NUL-terminated
string. This makes it annoying to wrap strings we have as a
pointer and a length.
Refactoring strbuf_add_wrapped_text and all of its
sub-functions to handle fixed-length strings turned out to
be really ugly. So this implementation is lame; it just
strdups the text and operates on the NUL-terminated version.
This should be fine as the strings we are wrapping are
generally pretty short. If it becomes a problem, we can
optimize later.

Sanity-check config variable names when adding and retrieving them. As a side
effect code duplication between git_config_set_multivar and get_value (in

This breaks a test in t1300 which used invalid section-less keys in the tests

no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples

diff: handle diffstat of rewritten binary files
The logic in builtin_diffstat assumes that a
complete_rewrite pair should have its lines counted. This is
nonsensical for binary files and leads to confusing things
like:
$ git diff --stat --summary HEAD^ HEAD
foo.rand | Bin 4096 -> 4096 bytes
1 files changed, 0 insertions(+), 0 deletions(-)
$ git diff --stat --summary -B HEAD^ HEAD
foo.rand | 34 +++++++++++++++-------------------
1 files changed, 15 insertions(+), 19 deletions(-)
rewrite foo.rand (100%)
So let's reorder the function to handle binary files first
(which from diffstat's perspective look like complete
rewrites anyway), then rewrites, then actual diffstats.
There are two bonus prizes to this reorder:
1. It gets rid of a now-superfluous goto.
2. The binary case is at the top, which means we can
further optimize it in the next patch.

Teach commit about CHERRY_PICK_HEAD
Previously the user was advised to use commit -c CHERRY_PICK_HEAD after
a conflicting cherry-pick. While this would preserve the original
commit's authorship, it would sadly discard cherry-pick's carefully
crafted MERGE_MSG (which contains the list of conflicts as well as the
original commit-id in the case of cherry-pick -x).
On the other hand, if a bare 'commit' were performed, it would preserve
the MERGE_MSG while resetting the authorship.
In other words, there was no way to simultaneously take the authorship
from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
This change fixes that situation. A bare 'commit' will now take the
authorship from CHERRY_PICK_HEAD and the commit message from MERGE_MSG.
If the user wishes to reset authorship, that must now be done explicitly
via --reset-author.
A side-benefit of passing commit authorship along this way is that we
can eliminate redundant authorship parsing code from revert.c.

Introduce CHERRY_PICK_HEAD
When a cherry-pick conflicts git advises:
$ git commit -c <original commit id>
to preserve the original commit message and authorship. Instead, let's
record the original commit id in CHERRY_PICK_HEAD and advise:
$ git commit -c CHERRY_PICK_HEAD
A later patch teaches git to handle the '-c CHERRY_PICK_HEAD' part.
Note that we record CHERRY_PICK_HEAD even in the case where there
are no conflicts so that we may use it to communicate authorship to
commit; this will then allow us to remove set_author_ident_env from
revert.c. However, we do not record CHERRY_PICK_HEAD when --no-commit
is used, as presumably the user intends to further edit the commit
and possibly even cherry-pick additional commits on top.

gitweb/gitweb.perl: don't call S_ISREG() with undef
Change S_ISREG($to_mode_oct) to S_ISREG($from_mode_oct) in the branch
that handles from modes, not to modes. This logic appears to have been
caused by copy/paste programming by Jakub Narebski in e8e41a93. It
would be better to rewrite this code not to be duplicated, but I
haven't done so.
This issue caused a failing test on perl 5.13.9, which has a warning
that turned this up:
gitweb.perl: Use of uninitialized value in subroutine entry at /home/avar/g/git/t/../gitweb/gitweb.perl line 4415.
Which caused the Git test suite to fail on this test:
./t9500-gitweb-standalone-no-errors.sh (Wstat: 256 Tests: 90 Failed: 84)
Failed tests: 1-8, 10-36, 38-45, 47-48, 50-88

gitweb/gitweb.perl: remove use of qw(...) as parentheses
Using the qw(...) construct as implicit parentheses was deprecated in
perl 5.13.5. Change the relevant code in gitweb to not use the
deprecated construct. The offending code was introduced in 3562198b by
Jakub Narebski.
The issue is that perl will now warn about this:
$ perl -wE 'for my $i qw(a b) { say $i }'
Use of qw(...) as parentheses is deprecated at -e line 1.
a
b
This caused gitweb.perl to warn on perl 5.13.5 and above, and these
tests to fail on those perl versions:
./t9501-gitweb-standalone-http-status.sh (Wstat: 256 Tests: 11 Failed: 10)
Failed tests: 2-11
Non-zero exit status: 1
./t9502-gitweb-standalone-parse-output.sh (Wstat: 256 Tests: 10 Failed: 9)

pull: propagate --progress to merge
Now that merge understands progress, we should pass it
along. While we're at it, pass along --no-progress, too.

merge: enable progress reporting for rename detection
The user can enable or disable it explicitly with the new
--progress, but it defaults to checking isatty(2).
This works only with merge-recursive and subtree. In theory
we could pass a progress flag to other strategies, but none
of them support progress at this point, so let's wait until
they grow such a feature before worrying about propagating
it.

add inexact rename detection progress infrastructure
We might spend many seconds doing inexact rename detection
with no output. It's nice to let the user know that
something is actually happening.
This patch adds the infrastructure, but no callers actually
turn on progress reporting.

commit: stop setting rename limit
For its post-commit summary, commit was explicitly setting
the default rename limit to 100. Presumably when the code
was added, it was necessary to do so. These days, however,
it will fall back properly to the diff default, and that
default has long since changed from 100.

bump rename limit defaults (again)
We did this once before in 5070591 (bump rename limit
defaults, 2008-04-30). Back then, we were shooting for about
1 second for a diff/log calculation, and 5 seconds for a
merge.
There are a few new things to consider, though:
1. Average processors are faster now.
2. We've seen on the mailing list some ugly merges where
not using inexact rename detection leads to many more
conflicts. Merges of this size take a long time
anyway, so users are probably happy to spend a little
bit of time computing the renames.
Let's bump the diff/merge default limits from 200/500 to
400/1000. Those are 2 seconds and 10 seconds respectively on
my modern hardware.
