t7510: use consistent &&-chains in loop

We check multiple commits in a loop. Because we want to
break out of the loop if any single iteration fails, we use
a subshell/exit like:

(
for i in $stuff
do
do-something $i || exit 1
done
)

However, we are inconsistent in our loop body. Some commands
get their own "|| exit 1", and others try to chain to the
next command with "&&", like:

X &&
Y || exit 1
Z || exit 1

This is a little hard to read and follow, because X and Y
are treated differently for no good reason. But much worse,
the second loop follows a similar pattern and gets it wrong.
"Y" is expected to fail, so we use "&& exit 1", giving us:

X &&
Y && exit 1
Z || exit 1

That gets the test for X wrong (we do not exit unless both X
fails and Y unexpectedly succeeds, but we would want to exit
if _either_ is wrong). We can write this clearly and
correctly by consistently using "&&", followed by a single
"|| exit 1", and negating Y with "!" (as we would in a
normal &&-chain). Like:

X &&
! Y &&
Z || exit 1

reuse cached commit buffer when parsing signaturesJeff King Fri, 13 Jun 2014 06:32:11 +0000 (02:32 -0400)

reuse cached commit buffer when parsing signatures

When we call show_signature or show_mergetag, we read the
commit object fresh via read_sha1_file and reparse its
headers. However, in most cases we already have the object
data available, attached to the "struct commit". This is
partially laziness in dealing with the memory allocation
issues, but partially defensive programming, in that we
would always want to verify a clean version of the buffer
(not one that might have been munged by other users of the
commit).

However, we do not currently ever munge the commit buffer,
and not using the already-available buffer carries a fairly
big performance penalty when we are looking at a large
number of commits. Here are timings on linux.git:

[baseline, no signatures]
$ time git log >/dev/null
real 0m4.902s
user 0m4.784s
sys 0m0.120s

[before]
$ time git log --show-signature >/dev/null
real 0m14.735s
user 0m9.964s
sys 0m0.944s

[after]
$ time git log --show-signature >/dev/null
real 0m9.981s
user 0m5.260s
sys 0m0.936s

Note that our user CPU time drops almost in half, close to
the non-signature case, but we do still spend more
wall-clock and system time, presumably from dealing with
gpg.

An alternative to this is to note that most commits do not
have signatures (less than 1% in this repo), yet we pay the
re-parsing cost for every commit just to find out if it has
a mergetag or signature. If we checked that when parsing the
commit initially, we could avoid re-examining most commits
later on. Even if we did pursue that direction, however,
this would still speed up the cases where we _do_ have
signatures. So it's probably worth doing either way.

commit: record buffer length in cache

Most callsites which use the commit buffer try to use the
cached version attached to the commit, rather than
re-reading from disk. Unfortunately, that interface provides
only a pointer to the NUL-terminated buffer, with no
indication of the original length.

For the most part, this doesn't matter. People do not put
NULs in their commit messages, and the log code is happy to
treat it all as a NUL-terminated string. However, some code
paths do care. For example, when checking signatures, we
want to be very careful that we verify all the bytes to
avoid malicious trickery.

This patch just adds an optional "size" out-pointer to
get_commit_buffer and friends. The existing callers all pass
NULL (there did not seem to be any obvious sites where we
could avoid an immediate strlen() call, though perhaps with
some further refactoring we could).

commit: convert commit->buffer to a slab

This will make it easier to manage the buffer cache
independently of the "struct commit" objects. It also
shrinks "struct commit" by one pointer, which may be
helpful.

Unfortunately it does not reduce the max memory size of
something like "rev-list", because rev-list uses
get_cached_commit_buffer() to decide not to show each
commit's output (and due to the design of slab_at, accessing
the slab requires us to extend it, allocating exactly the
same number of buffer pointers we dropped from the commit
structs).

convert logmsg_reencode to get_commit_buffer

Like the callsites in the previous commit, logmsg_reencode
already falls back to read_sha1_file when necessary.
However, I split its conversion out into its own commit
because it's a bit more complex.

We return either:

1. The original commit->buffer

2. A newly allocated buffer from read_sha1_file

3. A reencoded buffer (based on either 1 or 2 above).

while trying to do as few extra reads/allocations as
possible. Callers currently free the result with
logmsg_free, but we can simplify this by pointing them
straight to unuse_commit_buffer. This is a slight layering
violation, in that we may be passing a buffer from (3).
However, since the end result is to free() anything except
(1), which is unlikely to change, and because this makes the
interface much simpler, it's a reasonable bending of the
rules.

use get_commit_buffer to avoid duplicate code

For both of these sites, we already do the "fallback to
read_sha1_file" trick. But we can shorten the code by just
using get_commit_buffer.

Note that the error cases are slightly different when
read_sha1_file fails. get_commit_buffer will die() if the
object cannot be loaded, or is a non-commit.

For get_sha1_oneline, this will almost certainly never
happen, as we will have just called parse_object (and if it
does, it's probably worth complaining about).

For record_author_date, the new behavior is probably better;
we notify the user of the error instead of silently ignoring
it. And because it's used only for sorting by author-date,
somebody examining a corrupt repo can fallback to the
regular traversal order.

provide helpers to access the commit bufferJeff King Tue, 10 Jun 2014 21:40:39 +0000 (17:40 -0400)

provide helpers to access the commit buffer

Many sites look at commit->buffer to get more detailed
information than what is in the parsed commit struct.
However, we sometimes drop commit->buffer to save memory,
in which case the caller would need to read the object
afresh. Some callers do this (leading to duplicated code),
and others do not (which opens the possibility of a segfault
if somebody else frees the buffer).

Let's provide a pair of helpers, "get" and "unuse", that let
callers easily get the buffer. They will use the cached
buffer when possible, and otherwise load from disk using
read_sha1_file.

Note that we also need to add a "get_cached" variant which
returns NULL when we do not have a cached buffer. At first
glance this seems to defeat the purpose of "get", which is
to always provide a return value. However, some log code
paths actually use the NULL-ness of commit->buffer as a
boolean flag to decide whether to try printing the
commit. At least for now, we want to continue supporting
that use.

provide a helper to free commit buffer

This converts two lines into one at each caller. But more
importantly, it abstracts the concept of freeing the buffer,
which will make it easier to change later.

Note that we also need to provide a "detach" mechanism for a
tricky case in index-pack. We are passed a buffer for the
object generated by processing the incoming pack. If we are
not using --strict, we just calculate the sha1 on that
buffer and return, leaving the caller to free it. But if we
are using --strict, we actually attach that buffer to an
object, pass the object to the fsck functions, and then
detach the buffer from the object again (so that the caller
can free it as usual). In this case, we don't want to free
the buffer ourselves, but just make sure it is no longer
associated with the commit.

Note that we are making the assumption here that the
attach/detach process does not impact the buffer at all
(e.g., it is never reallocated or modified). That holds true
now, and we have no plans to change that. However, as we
abstract the commit_buffer code, this dependency becomes
less obvious. So when we detach, let's also make sure that
we get back the same buffer that we gave to the
commit_buffer code.

do not create "struct commit" with xcalloc

In both blame and merge-recursive, we sometimes create a
"fake" commit struct for convenience (e.g., to represent the
HEAD state as if we would commit it). By allocating
ourselves rather than using alloc_commit_node, we do not
properly set the "index" field of the commit. This can
produce subtle bugs if we then use commit-slab on the
resulting commit, as we will share the "0" index with
another commit.

We can fix this by using alloc_commit_node() to allocate.
Note that we cannot free the result, as it is part of our
commit allocator. However, both cases were already leaking
the allocated commit anyway, so there's nothing to fix up.

commit: push commit_index update into alloc_commit_node

Whenever we create a commit object via lookup_commit, we
give it a unique index to be used with the commit-slab API.
The theory is that any "struct commit" we create would
follow this code path, so any such struct would get an
index. However, callers could use alloc_commit_node()
directly (and get multiple commits with index 0).

Let's push the indexing into alloc_commit_node so that it's
hard for callers to get it wrong.

alloc: include any-object allocations in alloc_report

When 2c1cbec (Use proper object allocators for unknown
object nodes too, 2007-04-16), added a special "any_object"
allocator, it never taught alloc_report to report on it. To
do so we need to add an extra type argument to the REPORT
macro, as that commit did for DEFINE_ALLOCATOR.

replace dangerous uses of strbuf_attachJeff King Tue, 10 Jun 2014 21:38:38 +0000 (17:38 -0400)

replace dangerous uses of strbuf_attach

It is not a good idea to strbuf_attach an arbitrary pointer
just because a function you are calling wants a strbuf.
Attaching implies a transfer of memory ownership; if anyone
were to modify or release the resulting strbuf, we would
free() the pointer, leading to possible problems:

1. Other users of the original pointer might access freed
memory.

2. The pointer might not be the start of a malloc'd
area, so calling free() on it in the first place would
be wrong.

In the two cases modified here, we are fortunate that nobody
touches the strbuf once it is attached, but it is an
accident waiting to happen. Since the previous commit,
commit_tree and friends take a pointer/buf pair, so we can
just do away with the strbufs entirely.

commit_tree: take a pointer/len pair rather than a const strbuf

While strbufs are pretty common throughout our code, it is
more flexible for functions to take a pointer/len pair than
a strbuf. It's easy to turn a strbuf into such a pair (by
dereferencing its members), but less easy to go the other
way (you can strbuf_attach, but that has implications about
memory ownership).

This patch teaches commit_tree (and its associated callers
and sub-functions) to take such a pair for the commit
message rather than a strbuf. This makes passing the buffer
around slightly more verbose, but means we can get rid of
some dangerous strbuf_attach calls in the next patch.

repack: respect pack.writebitmaps

The config option to turn on bitmaps is read all the way
down in the plumbing of pack-objects. This makes it hard for
other options in the porcelain of repack to make decisions
based on the bitmap setting. For example,
repack.packKeptObjects tries to kick in by default only when
bitmaps are turned on. But it can't do so reliably because
it doesn't yet know whether we are using bitmaps.

This patch teaches repack to respect pack.writebitmaps. It
means we pass a redundant command-line flag to pack-objects,
but that's OK; it shouldn't affect the outcome.

repack: do not accidentally pack kept objects by defaultJeff King Tue, 10 Jun 2014 20:08:38 +0000 (16:08 -0400)

repack: do not accidentally pack kept objects by default

Commit ee34a2b (repack: add `repack.packKeptObjects` config
var, 2014-03-03) added a flag which could duplicate kept
objects, but did not mean to turn it on by default. Instead,
the option is tied by default to the decision to write
bitmaps, like:

if (pack_kept_objects < 0)
pack_kept_objects = write_bitmap;

after which we expect pack_kept_objects to be a boolean 0 or
1. However, that assignment neglects that write_bitmap is
_also_ a tri-state with "-1" as the default, and with
neither option given, we accidentally turn the option on.

This patch is the minimal fix to restore the desired
behavior for the default state. Further patches will fix the
more complicated cases.

Note the update to t7700. It failed to turn on bitmaps,
meaning we were actually confirming the wrong behavior!

shortlog: allow --exclude=<glob> to be passed

These two commands are supposed to be equivalent:

$ git log --exclude=refs/notes/\* --all --no-merges --since=2.days |
git shortlog
$ git shortlog --exclude=refs/notes/\* --all --no-merges --since=2.days

However, the latter does not understand the ref-exclusion command
line option, even though other options understood by "log", such as
"--all" and "--no-merges", are understood.

This was because e7b432c5 (revision: introduce --exclude=<glob> to

machinery. A new option understood by handle_revision_pseudo_opt()
must be told to handle_revision_opt() as well.

t5000, t5003: do not use test_cmp to compare binary files

test_cmp() is primarily meant to compare text files (and display the
difference for debug purposes).

Raw "cmp" is better suited to compare binary files (tar, zip, etc.).

On MinGW, test_cmp is a shell function mingw_test_cmp that tries to
read both files into environment, stripping CR characters (introduced
in commit 4d715ac0).

This function usually speeds things up, as fork is extremly slow on
Windows. But no wonder that this function is extremely slow and
sometimes even crashes when comparing large tar or zip files.

Slightly more rare occurrences of 'text \ ' with a backslash
in between spaces are handled correctly. Namely, the code in

does not reset 'last_space' when a backslash is encountered and the above

pack-objects: use free()+xcalloc() instead of xrealloc()+memset()

Whenever the hash table becomes too small then its size is increased,
the original part (and the added space) is zerod out using memset(),
and the table is rebuilt from scratch.

Simplify this proceess by returning the old memory using free() and
allocating the new buffer using xcalloc(), which already clears the
buffer for us. That way we avoid copying the old hash table contents
needlessly inside xrealloc().

While at it, use the first array member with sizeof instead of a
specific type. The old code used uint32_t and int, while index is
actually an array of int32_t. Their sizes are the same basically
everywhere, so it's not actually a problem, but the new code is
cleaner and doesn't have to be touched should the type be changed.

When looking for the index of a specfic string in that array, simply
use strcmp() instead of memcmp(). This avoids running over the end of
the string (e.g. with memcmp("Subject", "From", 7)) and gets rid of
magic string length constants.

sideband.c: do not use ANSI control sequence on non-terminal

Diagnostic messages received on the sideband #2 from the server side
are sent to the standard error with ANSI terminal control sequence
"\033[K" that erases to the end of line appended at the end of each
line.

However, some programs (e.g. GitExtensions for Windows) read and
interpret and/or show the message without understanding the terminal
control sequences, resulting them to be shown to their end users.
To help these programs, squelch the control sequence when the
standard error stream is not being sent to a tty.

NOTE: I considered to cover the case that a pager has already been
started. But decided that is probably not worth worrying about here,
though, as we shouldn't be using a pager for commands that do network

compat/bswap.h: fix endianness detection

The changes to make detection of endianness more portable had a bug
that breaks on (at least) Solaris x86.

The bug appears to be a simple copy/paste typo. It checks for
_BIG_ENDIAN and not _LITTLE_ENDIAN for both the case where we would
decide the system is big endian and little endian. Instead, the
second test should be for _LITTLE_ENDIAN and not _BIG_ENDIAN.

Two fixes were possible:

1. Change the negation order of the conditions in the second test.
2. Reverse the order of the conditions in the second test.

Use the second option so that the condition we expect is always a
positive check.

1. We drop the `test -z "$GIT_TEST_HTTPD"` check; this is
too simplistic since 83d842d, and we should let
lib-httpd.sh handle it.

2. We have to port over some of the old setup from t5538.

These were originally removed by 0232852 (t5537: move

accidentally re-added in 1ddb4d7 (Merge branch

This looks like an error in manual conflict resolution.
Here's what happened:

1. v1.9.0 shipped with the http tests in t5537.

2. We realized that this caused problems, and built
0232852 on top to move the tests to their own file.
This fix made it into v1.9.1.

3. We later had another fix in nd/upload-pack-shallow that
also touched t5537. It was built directly on v1.9.0.

When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

gc --auto: do not lock refs in the backgroundNguyễn Thái Ngọc Duy Sun, 25 May 2014 00:38:29 +0000 (07:38 +0700)

gc --auto: do not lock refs in the background

9f673f9 (gc: config option for running --auto in background -
2014-02-08) puts "gc --auto" in background to reduce user's wait
time. Part of the garbage collecting is pack-refs and pruning
reflogs. These require locking some refs and may abort other processes
trying to lock the same ref. If gc --auto is fired in the middle of a
script, gc's holding locks in the background could fail the script,
which could never happen before 9f673f9.

Keep running pack-refs and "reflog --prune" in foreground to stop
parallel ref updates. The remaining background operations (repack,
prune and rerere) should not impact running git processes.

remote prune: optimize "dangling symref" check/warning

When 'git remote prune' was used to delete many refs in a repository
with many refs, a lot of time was spent checking for (now) dangling
symbolic refs pointing to the deleted ref, since warn_dangling_symref()
was once per deleted ref to check all other refs in the repository.

Avoid this using the new warn_dangling_symrefs() function which
makes one pass over all refs and checks for all the deleted refs in
one go, after they have all been deleted.

remote: repack packed-refs once when deleting multiple refs

When 'git remote rm' or 'git remote prune' were used in a repository
with many refs, and needed to delete many remote-tracking refs, a lot
of time was spent deleting those refs since for each deleted ref,
repack_without_refs() was called to rewrite packed-refs without just
that deleted ref.

To avoid this, call repack_without_refs() first to repack without all
the refs that will be deleted, before calling delete_ref() to delete
each one completely. The call to repack_without_ref() in delete_ref()
then becomes a no-op, since packed-refs already won't contain any of
the deleted refs.

pretty.c: format string with truncate respects logOutputEncoding

Pretty format string %<(N,[ml]trunc)>%s truncates subject to a given
length with an appropriate padding. This works for non-ASCII texts when
i18n.logOutputEncoding is UTF-8 only (independently of a printed commit
message encoding) but does not work when i18n.logOutputEncoding is NOT
UTF-8.

In 7e77df3 (pretty: two phase conversion for non utf-8 commits, 2013-04-19)
'format_commit_item' function assumes commit message to be in UTF-8.
And that was so until ecaee80 (pretty: --format output should honor
logOutputEncoding, 2013-06-26) where conversion to logOutputEncoding was
added before calling 'format_commit_message'.

Correct this by converting a commit message to UTF-8 first (as it
assumed in 7e77df3 (pretty: two phase conversion for non utf-8 commits,
2013-04-19)). Only after that convert a commit message to an actual
logOutputEncoding.

t4205, t6006: add tests that fail with i18n.logOutputEncoding set

Pretty format string %<(N,[ml]trunc)>%s truncates subject to a given
length with an appropriate padding. This works for non-ASCII texts when
i18n.logOutputEncoding is UTF-8 only (independently of a printed commit

There were no breakages as far as were no tests for the case
when both a commit message and logOutputEncoding are not UTF-8.

Add failing tests for that which will be fixed in the next patch.

move "--follow needs one pathspec" rule to diff_setup_doneJeff King Tue, 20 May 2014 06:49:20 +0000 (02:49 -0400)

move "--follow needs one pathspec" rule to diff_setup_done

Because of the way "--follow" is implemented, we must have
exactly one pathspec. "git log" enforces this restriction,
but other users of the revision traversal code do not. For
example, "git format-patch --follow" will segfault during
try_to_follow_renames, as we have no pathspecs at all.

We can push this check down into diff_setup_done, which is
probably a better place anyway. It is the diff code that
introduces this restriction, so other parts of the code
should not need to care themselves.
