Since b19138b (git-svn: Make it incrementally faster by minimizing temp
files, v1.6.0), git-svn has been using the Git.pm temp_acquire and
temp_release mechanism to avoid unnecessary temp file churn and provide
a speed boost.
However, that change introduced a call to temp_acquire inside the
Git::SVN::Fetcher::close_file function for an 'svn_hash' temp file.
Because an SVN::Pool is active at the time this function is called, if
the Git::temp_acquire function ends up actually creating a new
FileHandle for the temp file (which it will the first time it's called
with the name 'svn_hash') that FileHandle will end up in the SVN::Pool
and should that pool have SVN::Pool::clear called on it that FileHandle
will be closed out from under Git::temp_acquire.
Since the only call site to Git::temp_acquire with the name 'svn_hash'
is inside the close_file function, if an 'svn_hash' temp file is ever
created its FileHandle is guaranteed to be created in the active
SVN::Pool.
This has not been a problem in the past because the SVN::Pool was not
being cleared. However, since dfa72fdb (git-svn: reload RA every
log-window-size, v2.2.0) the pool has been getting cleared periodically
at which point the FileHandle for the 'svn_hash' temp file gets closed.
Any subsequent calls to Git::temp_acquire for 'svn_hash', however,
succeed without creating/opening a new temporary file since it still has
the now invalid FileHandle in its cache. Callers that then attempt to
use that FileHandle fail with an error.
We avoid this problem by making sure the 'svn_hash' temp file is created
in the same place the 'svn_delta_...' and 'git_blob_...' temp files are
(and then temp_release'd) so that it can be safely used inside the
close_file function without having its FileHandle end up in an SVN::Pool
that gets cleared.
Additionally the Git.pm cat_blob function creates a bidirectional pipe
FileHandle using the IPC::Open2::open2 function. If that handle is
created too late, it also gets caught up in the SVN::Pool and incorrectly
closed by the SVN::Pool::clear call. But this only seems to happen with
more recent versions of Perl and svn.
To avoid this problem we add an explicit call to _open_cat_blob_if_needed
before the first call to SVN::Pool->new_default to make sure the open2
handle does not end up in the SVN::Pool.

When an import has finished, we run end_packfile() to
finalize the data and move the packfile into place. If this
process fails, we call die() and end up in our die_nicely()
handler. Which unfortunately includes running end_packfile
to save any progress we made. We enter the function again,
and start operating on the pack_data struct while it is in
an inconsistent state, leading to a segfault.
One way to trigger this is to simply start two identical
fast-imports at the same time. They will both create the
same packfiles, which will then try to create identically
named ".keep" files. One will win the race, and the other
will die(), and end up with the segfault.
Since 3c078b9, we already reset the pack_data pointer to
NULL at the end of end_packfile. That covers the case of us
calling die() right after end_packfile, before we have
reinitialized the pack_data pointer. This new problem is
quite similar, except that we are worried about calling
die() _during_ end_packfile, not right after. Ideally we
would simply set pack_data to NULL as soon as we enter the
function, and operate on a copy of the pointer.
Unfortunately, it is not so easy. pack_data is a global, and
end_packfile calls into other functions which operate on the
global directly. We would have to teach each of these to
take an argument, and there is no guarantee that we would
catch all of the spots.
Instead, we can simply use a static flag to avoid
recursively entering the function. This is a little less
elegant, but it's short and fool-proof.

The string in 'base' contains a path suffix to a specific object;
when its value is used, the suffix must either be filled (as in
stat_sha1_file, open_sha1_file, check_and_freshen_nonlocal) or

660c889e (sha1_file: add for_each iterators for loose and packed

neither and treated 'base' as a complete path to the "base" object

The trailing path after 'base' is still initialized to NUL, hiding

for_each_file_in_obj_subdir() function swallows ENOENT, so an error

git-compat-util: do not step on MAC_OS_X_VERSION_MIN_REQUIRED
MAC_OS_X_VERSION_MIN_REQUIRED may be defined by the builder to a
specific version in order to produce compatible binaries for a
particular system. Blindly defining it to MAC_OS_X_VERSION_10_6
is bad.
Additionally MAC_OS_X_VERSION_10_6 will not be defined on older
systems and should AvailabilityMacros.h be included on such as
system an error will result. However, using the explicit value
of 1060 (which is what MAC_OS_X_VERSION_10_6 is defined to) does
not solve the problem.
The changes that introduced stepping on MAC_OS_X_VERSION_MIN were
made in b195aa00 (git-compat-util: suppress unavoidable
Apple-specific deprecation warnings) to avoid deprecation
warnings.
Instead of blindly setting MAC_OS_X_VERSION_MIN to 1060 change
the definition of DEPRECATED_ATTRIBUTE to empty to avoid the
warnings. This preserves any MAC_OS_X_VERSION_MIN_REQUIRED
setting while avoiding the warnings as intended by b195aa00.

config_buf_ungetc: warn when pushing back a random character
Our config code simulates a stdio stream around a buffer,
but our fake ungetc() does not behave quite like the real
one. In particular, we only rewind the position by one
character, but do _not_ actually put the character from the
caller into position.
It turns out that this does not matter, because we only ever
push back the character we just read. In other words, such
an assignment would be a noop. But because the function is
called ungetc, and because it takes a character parameter,
it is a mistake waiting to happen.
Actually assigning the character into the buffer would be
ideal, but our pointer is actually a "const" copy of the
buffer. We do not know who the real owner of the buffer is
in this code, and would not want to munge their contents.
Instead, we can simply add an assertion that matches what
the current caller does, and will let us know if new callers
are added that violate the contract.

The decimal_width function originally appeared in blame.c as
"lineno_width", and was designed for calculating the
print-width of small-ish integer values (line numbers in
text files). In ec7ff5b, it was made into a reusable
function, and in dc801e7, we started using it to align
diffstats.
Binary files in a diffstat show byte counts rather than line
numbers, meaning they can be quite large (e.g., consider
adding or removing a 2GB file). decimal_width is not up to
the challenge for two reasons:
1. It takes the value as an "int", whereas large files may
easily surpass this. The value may be truncated, in
which case we will produce an incorrect value.
2. It counts "up" by repeatedly multiplying another
integer by 10 until it surpasses the value. This can
cause an infinite loop when the value is close to the
largest representable integer.
For example, consider using a 32-bit signed integer,
and a value of 2,140,000,000 (just shy of 2^31-1).
We will count up and eventually see that 1,000,000,000
is smaller than our value. The next step would be to
multiply by 10 and see that 10,000,000,000 is too
large, ending the loop. But we can't represent that
value, and we have signed overflow.
This is technically undefined behavior, but a common
behavior is to lose the high bits, in which case our
iterator will certainly be less than the number. So
we'll keep multiplying, overflow again, and so on.
This patch changes the argument to a uintmax_t (the same
type we use to store the diffstat information for binary
filese), and counts "down" by repeatedly dividing our value
by 10.

When we are parsing a config value, if we see a carriage
return, we fgetc the next character to see if it is a
line feed (in which case we silently drop the CR). If it
isn't, we then ungetc the character, and take the literal
CR.
But we never check whether we in fact got a character at
all. If the config file ends in CR, we will get EOF here,
and try to ungetc EOF. This works OK for a real stdio
stream. The ungetc returns an error, and the next fgetc will
then return EOF again.
However, our custom buffer-based stream is not so fortunate.
It happily rewinds the position of the stream by one
character, ignoring the fact that we fed it EOF. The next
fgetc call returns the final CR again, over and over, and we
end up in an infinite loop.

Documentation/git-remote.txt: stress that set-url is not for triangular
It seems to be a common mistake to try using a single remote
(e.g. 'origin') to fetch from one place (i.e. upstream) while
pushing to another (i.e. your publishing point).
That will never work satisfactorily, and it is easy to understand
why if you think about what refs/remotes/origin/* would mean in such
a world. It fundamentally cannot reflect the reality. If it
follows the state of your upstream, it cannot match what you have
published, and vice versa.
It may be that misinformation is spread by some people. Let's
counter them by adding a few words to our documentation.
- The description was referring to <oldurl> and <newurl>, but never
mentioned <name> argument you give from the command line. By
mentioning "remote <name>", stress the fact that it is configuring
a single remote.
- Add a reminder that explicitly states that this is about a single
remote, which the triangular workflow is not about.

dumb-http: do not pass NULL path to parse_pack_index
Once upon a time, dumb http always fetched .idx files
directly into their final location, and then checked their
validity with parse_pack_index. This was refactored in
commit 750ef42 (http-fetch: Use temporary files for
pack-*.idx until verified, 2010-04-19), which uses the
following logic:
1. If we have the idx already in place, see if it's
valid (using parse_pack_index). If so, use it.
2. Otherwise, fetch the .idx to a tempfile, check
that, and if so move it into place.
3. Either way, fetch the pack itself if necessary.
However, it got step 1 wrong. We pass a NULL path parameter
to parse_pack_index, so an existing .idx file always looks
broken. Worse, we do not treat this broken .idx as an
opportunity to re-fetch, but instead return an error,
ignoring the pack entirely. This can lead to a dumb-http
fetch failing to retrieve the necessary objects.
This doesn't come up much in practice, because it must be a
packfile that we found out about (and whose .idx we stored)
during an earlier dumb-http fetch, but whose packfile we
_didn't_ fetch. I.e., we did a partial clone of a
repository, didn't need some packfiles, and now a followup
fetch needs them.

"--indexed-objects" option to "rev-list", and it is only useful in
the context of "git rev-list" and not "git log". There are other
object traversal options that do not make sense for "git log" that
are shown in the manual page.
Move the description of "--indexed-objects" to the object traversal
section so that it sits together with its friends "--objects",
"--objects-edge", etc. and then show them only in "git rev-list"
documentation.

add -i: return from list_and_choose if there is no candidate
The list_and_choose() helper is given a prompt and a list, asks the
user to make selection from the list, and then returns a list of
items chosen. Even when it is given an empty list as the original
candidate set to choose from, it gave a prompt to the user, who can
only say "I am done choosing".
Return an empty result when the input is an empty list without
bothering the user. The existing caller must already have a logic
to say "Nothing to do" or an equivalent when the returned list is
empty (i.e. the user chose to select nothing) if it is necessary, so
no change to the callers is necessary.
This fixes the case where "add untracked" is asked in "git add -i"
and there is no untracked files in the working tree. We used to give
an empty list of files to choose from with a prompt, but with this
change, we no longer do.

Under --whitespace=fix option, match_fragment() function examines
the preimage (the common context and the removed lines in the patch)
and the file being patched and checks if they match after correcting
all whitespace errors. When they are found to match, the common
context lines in the preimage is replaced with the fixed copy,
because these lines will then be copied to the corresponding place
in the postimage by a later call to update_pre_post_images(). Lines
that are added in the postimage, under --whitespace=fix, have their
whitespace errors already fixed when apply_one_fragment() prepares
the preimage and the postimage, so in the end, application of the
patch can be done by replacing the block of text in the file being
patched that matched the preimage with what is in the postimage that
was updated by update_pre_post_images().
In the earlier days, fixing whitespace errors always resulted in
reduction of size, either collapsing runs of spaces in the indent to
a tab or removing the trailing whitespaces. These days, however,
some whitespace error fix results in extending the size.
250b3c6c (apply --whitespace=fix: avoid running over the postimage
buffer, 2013-03-22) tried to compute the final postimage size but
its math was flawed. It counted the size of the block of text in
the original being patched after fixing the whitespace errors on its
lines that correspond to the preimage. That number does not have
much to do with how big the final postimage would be.
Instead count (1) the added lines in the postimage, whose size is
the same as in the final patch result because their whitespace
errors have already been corrected, and (2) the fixed size of the
lines that are common.
apply: make update_pre_post_images() sanity check the given postlen
"git apply --whitespace=fix" used to be able to assume that fixing
errors will always reduce the size by e.g. stripping whitespaces at
the end of lines or collapsing runs of spaces into tabs at the
beginning of lines. An update to accomodate fixes that lengthens
the result by e.g. expanding leading tabs into spaces were made long
time ago but the logic miscounted the necessary space after such
whitespace fixes, leading to either under-allocation or over-usage
of already allocated space.
Illustrate this with a runtime sanity-check to protect us from
future breakage. The test was stolen from Kyle McKay who helped
to identify the problem.

-, which broke this test when run with mksh-50d. This commit fixes it.

rebase -i: use full object name internally throughout the script
In earlier days, the abbreviated commit object name shown to the end
users were generated with hardcoded --abbrev=7; 56895038 (rebase
-i: respect core.abbrev, 2013-09-28) tried to make it honor the user
specified core.abbrev, but it missed the very initial invocation of
the editor.
These days, we try to use the full 40-hex object names internally to
avoid ambiguity that can arise after rebase starts running. Newly
created objects during the rebase may share the same prefix with
existing commits listed in the insn sheet. These object names are
shortened just before invoking the sequence editor to present the
insn sheet to the end user, and then expanded back to full object
names when the editor returns.
But the code still used the shortened names when preparing the insn
sheet for the very first time, resulting "7 hexdigits or more"
output to the user. Change the code to use full 40-hex commit
object names from the very beginning to make things more uniform.

transport-helper: do not request symbolic refs to remote helpers
A typical remote helper will return a `list` of refs containing a symbolic
ref HEAD, pointing to, e.g. refs/heads/master. In the case of a clone, all
the refs are being requested through `fetch` or `import`, including the
symbolic ref.
While this works properly, in some cases of a fetch, like `git fetch url`
or `git fetch origin HEAD`, or any fetch command involving a symbolic ref
without also fetching the corresponding ref it points to, the fetch command
fails with:
(in the case the remote helper returned '?' values to the `list` command).
This is because there is only one ref given to fetch(), and it's not
further resolved to something at the end of fetch_with_import().
While this can be somehow handled in the remote helper itself, by adding
a refspec for the symbolic ref, and storing an explicit ref in a private
namespace, and then handling the `import` for that symbolic ref
specifically, very few existing remote helpers are actually doing that.
So, instead of requesting the exact list of wanted refs to remote helpers,
treat symbolic refs differently and request the ref they point to instead.
Then, resolve the symbolic refs values based on the pointed ref.
This assumes there is no more than one level of indirection (a symbolic
ref doesn't point to another symbolic ref).
