For users with "store-passwords = no" set in the "[auth]" section of
their ~/.subversion/config, SVN 1.9.0+ would fail with the
following message when attempting to call svn_auth_set_parameter:
Value is not a string (or undef) at Git/SVN/Ra.pm
Ironically, this breakage was caused by r1553823 in subversion:
"Make svn_auth_set_parameter() usable from Perl bindings."
Since 2007 (602015e0e6), git-svn has used a workaround to make
svn_auth_set_parameter usable internally. However this workaround
breaks under SVN 1.9+, which deals properly with the type mapping
and fails to recognize our workaround.
For pre-1.9.0 SVN, we continue to use the existing workaround for
the lack of proper type mapping in the bindings.
Tested under subversion 1.6.17 and 1.9.3.
I've also verified r1553823 was not backported to SVN 1.8.x:

Since b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-07-11),
git-tag has started showing tags with ambiguous names (i.e.,
when both "heads/foo" and "tags/foo" exists) as "tags/foo"
instead of just "foo". This is both:
- pointless; the output of "git tag" includes only
refs/tags, so we know that "foo" means the one in
"refs/tags".
and
- ambiguous; in the original output, we know that the line
"foo" means that "refs/tags/foo" exists. In the new
output, it is unclear whether we mean "refs/tags/foo" or
"refs/tags/tags/foo".
The reason this happens is that commit b7cc53e9 switched
git-tag to use ref-filter's "%(refname:short)" output
formatting, which was adapted from for-each-ref. This more
general code does not know that we care only about tags, and
uses shorten_unambiguous_ref to get the short-name. We need
to tell it that we care only about "refs/tags/", and it
should shorten with respect to that value.
In theory, the ref-filter code could figure this out by us
passing FILTER_REFS_TAGS. But there are two complications
there:
1. The handling of refname:short is deep in formatting
code that does not even have our ref_filter struct, let
alone the arguments to the filter_ref struct.
2. In git v2.7.0, we expose the formatting language to the
user. If we follow this path, it will mean that
"%(refname:short)" behaves differently for "tag" versus
"for-each-ref" (including "for-each-ref refs/tags/"),
which can lead to confusion.
Instead, let's add a new modifier to the formatting
language, "strip", to remove a specific set of prefix
components. This fixes "git tag", and lets users invoke the
same behavior from their own custom formats (for "tag" or
"for-each-ref") while leaving ":short" with its same
consistent meaning in all places.
We introduce a test in t7004 for "git tag", which fails
without this patch. We also add a similar test in t3203 for
"git branch", which does not actually fail. But since it is
likely that "branch" will eventually use the same formatting
code, the test helps defend against future regressions.

'git subtree split' can incorrectly skip a merge even when both parents
act on the subtree, provided the merge results in a tree identical to
one of the parents. Fix by copying the merge if at least one parent is
non-identical, and the non-identical parent is not an ancestor of the
identical parent.
Also, add a test case which checks that a descendant remains a

Commit 348d4f2 (filter-branch: skip index read/write when
possible, 2015-11-06) taught filter-branch to optimize out
the final "git write-tree" when we know we haven't touched
the tree with any of our filters. It does by simply putting
the literal text "$commit^{tree}" into the "$tree" variable,
avoiding a useless rev-parse call.
However, when we pass this to git_commit_non_empty_tree(),
it gets confused; it resolves "$commit^{tree}" itself, and
compares our string to the 40-hex sha1, which obviously
doesn't match. As a result, "--prune-empty" (or any custom
filter using git_commit_non_empty_tree) will fail to drop
an empty commit (when filter-branch is used without a tree
or index filter).
Let's resolve $tree to the 40-hex ourselves, so that
git_commit_non_empty_tree can work. Unfortunately, this is a
bit slower due to the extra process overhead:
$ cd t/perf && ./run 348d4f2 HEAD p7000-filter-branch.sh
[...]
Test 348d4f2 HEAD
--------------------------------------------------------------
7000.2: noop filter 3.76(0.24+0.26) 4.54(0.28+0.24) +20.7%
We could try to make git_commit_non_empty_tree more clever.
However, the value of $tree here is technically
user-visible. The user can provide arbitrary shell code at
this stage, which could itself have a similar assumption to
what is in git_commit_non_empty_tree. So the conservative
choice to fix this regression is to take the 20% hit and
give the pre-348d4f2 behavior. We still end up much faster
than before the optimization:
$ cd t/perf && ./run 348d4f2^ HEAD p7000-filter-branch.sh
[...]
Test 348d4f2^ HEAD
--------------------------------------------------------------
7000.2: noop filter 9.51(4.32+0.40) 4.51(0.28+0.23) -52.6%

After rebasing, we call "gc --auto" to clean up if we
created a lot of loose objects. However, we do so inside an
&&-chain. If "gc --auto" fails (e.g., because a previous
background gc blocked us by leaving "gc.log" in place),
then:
1. We will fail to clean up the state directory, leaving
the user stuck in the rebase forever (even "git am
--abort" doesn't work, because it calls "gc --auto"!).
2. In some cases, we may return a bogus exit code from
rebase, indicating failure when everything except the
auto-gc succeeded.
We can fix this by ignoring the exit code of "gc --auto".

In shared repositories, we have to be careful when writing files whose
permissions do not allow users other than the owner to write them.
In particular, we force the marks file of fast-export and the FETCH_HEAD
when fetching to be rewritten from scratch.
This commit does not touch other calls to fopen() that want to
write files:
- commands that write to working tree files (core.sharedRepository
does not affect permission bits of working tree files),
e.g. .rej file created by "apply --reject", result of applying a
previous conflict resolution by "rerere", "git merge-file".
- git am, when splitting mails (git-am correctly cleans up its directory
after finishing, so there is no need to share those files between users)
- git submodule clone, when writing the .git file, because the file
will not be overwritten
- git_terminal_prompt() in compat/terminal.c, because it is not writing to
a file at all
- git diff --output, because the output file is clearly not intended to be
shared between the users of the current repository
- git fast-import, when writing a crash report, because the reports' file
names are unique due to an embedded process ID
- mailinfo() in mailinfo.c, because the output is clearly not intended to
be shared between the users of the current repository
- check_or_regenerate_marks() in remote-testsvn.c, because this is only
used for Git's internal testing
- git fsck, when writing lost&found blobs (this should probably be
changed, but left as a low-hanging fruit for future contributors).
Note that this patch does not touch callers of write_file() and
write_file_gently(), which would benefit from the same scrutiny as
to usage in shared repositories. Most notable users are branch,
daemon, submodule & worktree, and a worrisome call in transport.c
when updating one ref (which ignores the shared flag).

git reflog (ab)uses the log machinery to display its list of log
entries. To do so it must fake commit parent information for the log
walker.
For refs in refs/heads this is no problem, as they should only ever
point to commits. Tags and other refs however can point to anything,
thus their reflog may contain non-commit objects.
To avoid segfaulting, we check whether reflog entries are commits before
feeding them to the log walker and skip any non-commits. This means that
git reflog output will be incomplete for such refs, but that's one step
up from segfaulting. A more complete solution would be to decouple git
reflog from the log walker machinery.

The byte-swapping code automatically decides, based on the
platform, whether it is sensible to cast and do a potentially
unaligned ntohl(), or to pick individual bytes out of an
array.
It can be handy to override this decision, though, when
turning on compiler flags that will complain about unaligned
loads (such as -fsanitize=undefined). This patch adds a
macro check to make this possible.
There's no nice Makefile knob here; this is for prodding at

It's fine to access the MSB, because it's unsigned. However,
