package/git: bump to version 2.39.0
The git package in Buildroot is quite lagging behind (v2.31.4, released on July 12, 2022 while the baseline v2.31.0 was released on March 15, 2021). Bump the package to v2.39.0 (released December 12, 2022). While at it, also replace patch fixing uclibc no threads build with two patches cherry-picked from upstream next branch, which fixes the same issue by fixing the handling of flockfile(), funlockfile(), and getc_unlocked() declarations. These patches missed the release but planned for next maintenance release (v2.39.1). The reason for replacing the patch is when original fix patch was upstreamed [1], Jeff King noted that the build failure root cause was flockfile() is defined regardless of whether uclibc is configured with threads support or not [2]. Release notes for v2.39.0 is available on release announcement on Git mailing list at [3].

To avoid this build failure, check if flockfile is available before

Subject: [PATCH] git-compat-util: avoid redefining system function names
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
Our git-compat-util header defines a few noop wrappers for system
|
||||
functions if they are not available. This was originally done with a
|
||||
macro, but in 15b52a44e0 (compat-util: type-check parameters of no-op
|
||||
replacement functions, 2020-08-06) we switched to inline functions,
|
||||
because it gives us basic type-checking.
|
||||
|
||||
This can cause compilation failures when the system _does_ declare those
|
||||
functions but we choose not to use them, since the compiler will
|
||||
complain about the redeclaration. This was seen in the real world when
|
||||
compiling against certain builds of uclibc, which may leave
|
||||
_POSIX_THREAD_SAFE_FUNCTIONS unset, but still declare flockfile() and
|
||||
funlockfile().
|
||||
|
||||
It can also be seen on any platform that has setitimer() if you choose
|
||||
to compile without it (which plausibly could happen if the system
|
||||
implementation is buggy). E.g., on Linux:
|
||||
|
||||
$ make NO_SETITIMER=IWouldPreferNotTo git.o
|
||||
CC git.o
|
||||
In file included from builtin.h:4,
|
||||
from git.c:1:
|
||||
git-compat-util.h:344:19: error: conflicting types for ‘setitimer’; have ‘int(int, const struct itimerval *, struct itimerval *)’

||||

||||

|
||||

|
||||
make: *** [Makefile:2714: git.o] Error 1
|
||||
|
||||
Here I think the compiler is complaining about the lack of "restrict"
|
||||
annotations in our version, but even if we matched it completely (and
|
||||
there is no way to match all platforms anyway), it would still complain
|
||||
about a static declaration following a non-static one. Using macros
|
||||
doesn't have this problem, because the C preprocessor rewrites the name
|
||||
in our code before we hit this level of compilation.
|
||||
|
||||
One way to fix this would just be to revert most of 15b52a44e0. What we
|
||||
really cared about there was catching build problems with
|
||||
precompose_argv(), which most platforms _don't_ build, and which is our
|
||||
custom function. So we could just switch the system wrappers back to
|
||||
macros; most people build the real versions anyway, and they don't
|
||||
change. So the extra type-checking isn't likely to catch bugs.
|
||||
|
||||
But with a little work, we can have our cake and eat it, too. If we
|
||||
define the type-checking wrappers with a unique name, and then redirect
|
||||
the system names to them with macros, we still get our type checking,
|
||||
but without redeclaring the system function names.

Subject: [PATCH] git-compat-util: undefine system names before redeclaring
|
||||
them
|
||||
|
||||
When we define a macro to point a system function (e.g., flockfile) to
|
||||
our custom wrapper, we should make sure that the system did not already
|
||||
define it as a macro. This is rarely a problem, but can cause
|
||||
compilation failures if both of these are true:
|
||||
|
||||
- we decide to define our own wrapper even though the system provides
|
||||
the function; we know this happens at least with uclibc, which may
|
||||
declare flockfile, etc, without _POSIX_THREAD_SAFE_FUNCTIONS
|
||||
|
||||
- the system version is declared as a macro; we know this happens at
|
||||
least with uclibc's version of getc_unlocked()
|
||||
|
||||
So just handling getc_unlocked() would be sufficient to deal with the
|
||||
real-world case we've seen. But since it's easy to do, we may as well be
|
||||
defensive about the other macro wrappers added in the previous patch.
