chain kill signals for cleanup functions
If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:
do_cleanup(); /* actual work */
signal(signo, SIG_DFL); /* restore previous behavior */
raise(signo); /* deliver signal, killing ourselves */
For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.
This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,
and use sigchain_pop to restore whoever was before you in
the stack.

diff: refactor tempfile cleanup handling
There are two pieces of code that create tempfiles for diff:
run_external_diff and run_textconv. The former cleans up its
tempfiles in the face of premature death (i.e., by die() or
by signal), but the latter does not. After this patch, they
will both use the same cleanup routines.
To make clear what the change is, let me first explain what
happens now:
- run_external_diff uses a static global array of 2
diff_tempfile structs (since it knows it will always
need exactly 2 tempfiles). It calls prepare_temp_file
(which doesn't know anything about the global array) on
each of the structs, creating the tempfiles that need to
be cleaned up. It then registers atexit and signal
handlers to look through the global array and remove the
tempfiles. If it succeeds, it calls the handler manually
(which marks the tempfile structs as unused).
- textconv has its own tempfile struct, which it allocates
using prepare_temp_file and cleans up manually. No
signal or atexit handlers.
The new code moves the installation of cleanup handlers into
the prepare_temp_file function. Which means that that
function now has to understand that there is static tempfile
storage. So what happens now is:
- run_external_diff calls prepare_temp_file
- prepare_temp_file calls claim_diff_tempfile, which
allocates an unused slot from our global array
- prepare_temp_file installs (if they have not already
been installed) atexit and signal handlers for cleanup
- prepare_temp_file sets up the tempfile as usual
- prepare_temp_file returns a pointer to the allocated
tempfile
The advantage being that run_external_diff no longer has to
care about setting up cleanup handlers. Now by virtue of
calling prepare_temp_file, run_textconv gets the same
benefit, as will any future users of prepare_temp_file.
There are also a few side benefits to the specific
implementation:
- we now install cleanup handlers _before_ allocating the
tempfile, closing a race which could leave temp cruft
- when allocating a slot in the global array, we will now
detect a situation where the old slots were not properly
vacated (i.e., somebody forgot to call remove upon
leaving the function). In the old code, such a situation
would silently overwrite the tempfile names, meaning we
would forget to clean them up. The new code dies with a
bug warning.
- we make sure only to install the signal handler once.
This isn't a big deal, since we are just overwriting the
old handler, but will become an issue when a later patch
converts the code to use sigchain

A git patch that does not change the executable bit records the mode bits
on its "index" line. "git apply" used to interpret this mode exactly the
same way as it interprets the mode recorded on "new mode" line, as the
wish by the patch submitter to set the mode to the one recorded on the
line.
The reason the mode does not agree between the submitter and the receiver
in the first place is because there is _another_ commit that only appears
on one side but not the other since their histories diverged, and that
commit changes the mode. The patch has "index" line but not "new mode"
line because its change is about updating the contents without affecting
the mode. The application of such a patch is an explicit wish by the
submitter to only cherry-pick the commit that updates the contents without
cherry-picking the commit that modifies the mode. Viewed this way, the
current behaviour is problematic, even though the command does warn when
the mode of the path being patched does not match this mode, and a careful
user could detect this inconsistencies between the patch submitter and the
patch receiver.
This changes the semantics of the mode recorded on the "index" line;
instead of interpreting it as the submitter's wish to set the mode to the
recorded value, it merely informs what the mode submitter happened to
have, and the presense of the "index" line is taken as submitter's wish to
keep whatever the mode is on the receiving end.
This is based on the patch originally done by Alexander Potashev with a
minor fix; the tests are mine.

while other commands work fine.
"git pull" fails because POSIX shells have a notion of current working
directory that is different from getcwd(). The shell stores this path
in PWD. As a result, "cd ../" can be interpreted differently in a
shell script than chdir("../") in a C program. The shell interprets
"../" by essentially stripping the last textual path component from
PWD, whereas C chdir() follows the ".." link in the current directory
on the filesystem. When PWD is a symlink, these are different
destinations. As a result, Git's C commands find the correct
top-level working tree, and shell scripts do not.
Changes:
* When interpreting a relative upward (../) path in cd_to_toplevel,
prepend the cwd without symlinks, given by /bin/pwd
* Add tests for cd_to_toplevel and "git pull" in a symlinked
directory that failed before this fix, plus contrasting scenarios
that already worked

rebase -i -p: Fix --continue after a merge could not be redone
When a merge that has a conflict was rebased, then rebase stopped to let
the user resolve the conflicts. However, thereafter --continue failed
because the author-script was not saved. (This is rebase -i's way to
preserve a commit's authorship.) This fixes it by doing taking the same
failure route after a merge that is also taken after a normal cherry-pick.

Show a failure of rebase -p if the merge had a conflict
This extends t3409-rebase-preserve-merges by a case where the merge that
is rebased has a conflict. Therefore, the rebase stops and expects that
the user resolves the conflict. However, currently rebase --continue
fails because .git/rebase-merge/author-script is missing.
The test script had allocated two identical clones, but only one of them
(clone2) was used. Now we use both as indicated in the comment. Also,
two instances of && was missing in the setup part.

fast-import: make tagger information optional
Even though newer Porcelain tools always record the tagger information
when creating new tags, export/import pair should be able to faithfully
reproduce ancient tag objects that lack tagger information.

SubmittingPatches: mention the usage of real name in Signed-off-by: lines
Especially with something that is supposed to hopefully have some legal
value down the line if somebody starts making noises, it really would be
nice to have a real person to associate things with. Suggest this in the
SubmittingPatches document.
