push: mention "push.default=tracking" in the documentation

Change the documentation for push.tracking=* to re-include a mention

53c4031 ("push.default: Rename 'tracking' to 'upstream'", 2011-02-16),

7 years agopickaxe: fix segfault with '-S<...> --pickaxe-regex'

pickaxe: fix segfault with '-S<...> --pickaxe-regex'

'git {log,diff,...} -S<...> --pickaxe-regex' can segfault as a result
of out-of-bounds memory reads.

diffcore-pickaxe.c:contains() looks for all matches of the given regex
in a buffer in a loop, advancing the buffer pointer to the end of the
last match in each iteration.  When we switched to REG_STARTEND in
b7d36ffca (regex: use regexec_buf(), 2016-09-21), we started passing
the size of that buffer to the regexp engine, too.  Unfortunately,
this buffer size is never updated on subsequent iterations, and as the
buffer pointer advances on each iteration, this "bufptr+bufsize"
points past the end of the buffer.  This results in segmentation
fault, if that memory can't be accessed.  In case of 'git log' it can
also result in erroneously listed commits, if the memory past the end
of buffer is accessible and happens to contain data matching the
regex.

Reduce the buffer size on each iteration as the buffer pointer is
advanced, thus maintaining the correct end of buffer location.
Furthermore, make sure that the buffer pointer is not dereferenced in
the control flow statements when we already reached the end of the
buffer.

The new test is flaky, I've never seen it fail on my Linux box even
without the fix, but this is expected according to db5dfa3 (regex:
-G<pattern> feeds a non NUL-terminated string to regexec() and fails,
2016-09-21).  However, it did fail on Travis CI with the first (and
incomplete) version of the fix, and based on that commit message I
would expect the new test without the fix to fail most of the time on
Windows.

7 years agorun-command: fix segfault when cleaning forked async process
Jeff King [Fri, 17 Mar 2017 23:20:04 +0000 (19:20 -0400)]
run-command: fix segfault when cleaning forked async process

Callers of the run-command API may mark a child as
"clean_on_exit"; it gets added to a list and killed when the
main process dies.  Since commit 46df6906f
(execv_dashed_external: wait for child on signal death,
2017-01-06), we respect an extra "wait_after_clean" flag,
which we expect to find in the child_process struct.

When Git is built with NO_PTHREADS, we start "struct
async" processes by forking rather than spawning a thread.
The resulting processes get added to the cleanup list but
they don't have a child_process struct, and the cleanup
function ends up dereferencing NULL.

We should notice this case and assume that the processes do
not need to be waited for (i.e., the same behavior they had
before 46df6906f).

index-pack: make pointer-alias fallbacks safer

The final() function accepts a NULL value for certain
parameters, and falls back to writing into a reusable "name"
buffer, and then either:

  1. For "keep_name", requiring all uses to do "keep_name ?
     keep_name : name.buf". This is awkward, and it's easy
     to accidentally look at the maybe-NULL keep_name.

  2. For "final_index_name" and "final_pack_name", aliasing
     those pointers to the "name" buffer. This is easier to
     use, but the aliased pointers become invalid after the
     buffer is reused (this isn't a bug now, but it's a
     potential pitfall).

One way to make this safer would be to introduce an extra
pointer to do the aliasing, and have its lifetime match the
validity of the "name" buffer. But it's still easy to
accidentally use the wrong name (i.e., to use
"final_pack_name" instead of the aliased pointer).

Instead, let's use three separate buffers that will remain
valid through the function. That makes it safe to alias the
pointers and use them consistently. The extra allocations
shouldn't matter, as this function is not performance
sensitive.

The odb_pack_keep() function generates the name of a .keep
file and opens it. This has two problems:

  1. It requires a fixed-size buffer to create the filename
     and doesn't notice when the result is truncated.

  2. Of the two callers, one sometimes wants to open a
     filename it already has, which makes things awkward (it
     has to do so manually, and skips the leading-directory
     creation).

Instead, let's have odb_pack_keep() just open the file.
Generating the name isn't hard, and a future patch will
switch callers over to odb_pack_name() anyway.

rev-parse: simplify parsing of ref options

All of these options do the same thing "--foo" iterates over
the "foo" refs, and "--foo=<glob>" does the same with a
glob. We can factor this into its own function to avoid
repeating ourselves.

There are two subtleties to note:

  - the original called for_each_branch_ref(), etc, in the
    non-glob case. Now we will call for_each_ref_in("refs/heads/")
    which is exactly what for_each_branch_ref() did under
    the hood.

  - for --glob, we'll call for_each_glob_ref_in() with a
    NULL "prefix" argument. Which is exactly what
    for_each_glob_ref() was doing already.

So both cases should behave identically, and it seems
reasonable to assume that this will remain the same. The
functions we are calling now are the more-generic ones, and
the ones we are dropping are just convenience wrappers.
