060fe57184 Fix a test failure (t9500-*.sh) on cygwin
On filesystems where it is appropriate to set core.filemode
to false, test 29 ("commitdiff(0): mode change") fails when
git-commit does not notice a file (execute) permission change.

A fix requires noting the new file execute permission in the
index with a "git update-index --chmod=+x", prior to the commit.
Add a function (note_chmod) which implements this idea, and
insert a call in each test that modifies the x permission.

63c4024ff0 git-gui: Don't delete send on Windows as it doesn't exist
The Windows port of Tk does not have the send command so we
cannot delete it from our global namespace, but the Mac OS
X and X11 ports do have it.  Switching this delete attempt
into a catch makes send go away, or stay away.

674d172730 Rework pretty_print_commit to use strbufs instead of custom buffers.
Also remove the "len" parameter, as:
  (1) it was used as a max boundary, and every caller used ~0u
  (2) we check for final NUL no matter what, so it doesn't help for speed.

  As a result most of the pp_* function takes 3 arguments less, and we need
a lot less local variables, this makes the code way more readable, and
easier to extend if needed.

  This patch also fixes some spacing and cosmetic issues.

  This patch also fixes (as a side effect) a memory leak intoruced in
builtin-archive.c at commit df4a394f (fmt was xmalloc'ed and not free'd)

f1696ee398 Strbuf API extensions and fixes.
* Add strbuf_rtrim to remove trailing spaces.
  * Add strbuf_insert to insert data at a given position.
  * Off-by one fix in strbuf_addf: strbuf_avail() does not counts the final
    \0 so the overflow test for snprintf is the strict comparison. This is
    not critical as the growth mechanism chosen will always allocate _more_
    memory than asked, so the second test will not fail. It's some kind of
    miracle though.
  * Add size extension hints for strbuf_init and strbuf_read. If 0, default
    applies, else:
      + initial buffer has the given size for strbuf_init.
      + first growth checks it has at least this size rather than the
        default 8192.

a4503a15af Make --no-thin the default in git-push to save server resources
1) pushes happen less often than fetches, so the bandwidth saving is
   much less visible in that case overall.

2) thin packs have to be complemented with missing delta bases to be
   valid, so many received thin packs will take more disk space.

3) the bother of repacking should be distributed amongst "clients"
   i.e. fetchers and pushers as much as possible, and not the server
   being fetched or pushed, to keep disk and CPU usage low on the
   server.

This is why a fetch should get thin packs but a push should not.

Both Nico and I have been assuming that --no-thin was the default
behavior of git-push ever since Nico introduced --fix-thin into the
index-pack process, which allowed fetch and receive-pack to avoid
exploding packfiles received during transfer.  This patch finally
makes it so.

aba91192ae git-tag -s must fail if gpg cannot sign the tag.
Most of this patch code and message was written by Shawn O. Pearce.
I made some tests to know what the problem was, and then I changed
the code related with the SIGPIPE signal.

If the user has misconfigured `user.signingkey` in their .git/config
or just doesn't have any secret keys on their keyring and they ask
for a signed tag with `git tag -s` we better make sure the resulting
tag was actually signed by gpg.

Prior versions of builtin git-tag allowed this failure to slip
by without error as they were not checking the return value of
the finish_command() so they did not notice when gpg exited with
an error exit status.  They also did not fail if gpg produced an
empty output or if read_in_full received an error from the read
system call while trying to read the pipe back from gpg.

Finally, we did not actually honor any return value from the do_sign
function as it returns ssize_t but was being stored into an unsigned
long.  This caused the compiler to optimize out the die condition,
allowing git-tag to continue along and create the tag object.

However, when gpg gets a wrong username, it exits before any read was done
and then the writing process receives SIGPIPE and program is terminated.
By ignoring this signal, anyway, the function write_or_die gets EPIPE from
write_in_full and exits returning 0 to the system without a message.
Here we better call to write_in_full directly so we can fail
printing a message and return safely to the caller.

With these issues fixed `git-tag -s` will now fail to create the
tag and will report a non-zero exit status to its caller, thereby
allowing automated helper scripts to detect (and recover from)
failure if gpg is not working properly.

8938410189 git-gui: Trim trailing slashes from untracked submodule names
Oddly enough `git ls-files --others` supplies us the name of an
untracked submodule by including the trailing slash but that
same git version will not accept the name with a trailing slash
through `git update-index --stdin`.  Stripping off that final
slash character before loading it into our file lists allows
git-gui to stage changes to submodules just like any other file.

This change should give git-gui users some basic submodule support,
but it is strictly at the plumbing level as we do not actually know
about calling the git-submodule porcelain that is a recent addition
to git 1.5.3.

3b9dfde3d6 git-gui: Assume untracked directories are Git submodules
If `git ls-files --others` returned us the name of a directory then
it is because Git has decided that this directory itself contains a
valid Git repository and its files shouldn't be listed as untracked

In such a case we should label the object as a Git repository and
not just as a directory.

d2100860fd diff-delta.c: pack the index structure
In normal use cases, the performance wins are not overly impressive:
we get something like 5-10% due to the slightly better locality of
memory accesses using the packed structure.

However, since the data structure for index entries saves 33% of
memory on 32-bit platforms and 40% on 64-bit platforms, the behavior
when memory gets limited should be nicer.

This is a rather well-contained change.  One obvious improvement would
be sorting the elements in one bucket according to their hash, then
using binary probing to find the elements with the right hash value.

As it stands, the output should be strictly the same as previously
unless one uses the option for limiting the amount of used memory, in
which case the created packs might be better.

...even though git-gui can add that same symlink to the index just
fine.

This patch fix this by adding a check.

c63fe3b2dc git-gui: Avoid use of libdir in Makefile
Dmitry V. Levin pointed out that on GNU linux libdir is often used
in Makefiles to mean "/usr/lib" or "/usr/lib64", a directory that
is meant to hold platform-specific binary files.  Using a different
libdir meaning here in git-gui's Makefile breaks idomatic expressions
like rpm specifile "make libdir=%_libdir".

Originally I asked that the git.git Makefile undefine libdir before
it calls git-gui's own Makefile but it turns out this is very hard
to do, if not impossible.  Renaming our libdir to gg_libdir resolves
this case with a minimum amount of fuss on our part.

cff93397ab git-gui: Disable Tk send in all git-gui sessions
The Tk designers blessed us with the "send" command, which on X11
will allow anyone who can connect to your X server to evaluate any
Tcl code they desire within any running Tk process.  This is just
plain nuts.  If git-gui wants someone running Tcl code within it
then would ask someone to supply that Tcl code to it; waiting for
someone to drop any random Tcl code into us is not fantastic idea.

By renaming send to the empty name the procedure will be removed
from the global namespace and Tk will stop responding to random Tcl
evaluation requests sent through the X server.  Since there is no
facility to filter these requests it is unlikely that we will ever
consider enabling this command.

b449f4cfc9 Rework strbuf API and semantics.
The gory details are explained in strbuf.h. The change of semantics this
patch enforces is that the embeded buffer has always a '\0' character after
its last byte, to always make it a C-string. The offs-by-one changes are all
related to that very change.

  A strbuf can be used to store byte arrays, or as an extended string
library. The `buf' member can be passed to any C legacy string function,
because strbuf operations always ensure there is a terminating \0 at the end
of the buffer, not accounted in the `len' field of the structure.

  A strbuf can be used to generate a string/buffer whose final size is not
really known, and then "strbuf_detach" can be used to get the built buffer,
and keep the wrapping "strbuf" structure usable for further work again.

  Other interesting feature: strbuf_grow(sb, size) ensure that there is
enough allocated space in `sb' to put `size' new octets of data in the
buffer. It helps avoiding reallocating data for nothing when the problem the
strbuf helps to solve has a known typical size.

4dbfe2e9bd git-svn: always use --first-parent
This makes git-svn unconditionally invoke git-log with --first-parent when
it is trying to discover its upstream subversion branch and collecting the
commit ids which should be pushed to it with dcommit. The reason for always
using --first-parent is to make git-svn behave in a predictable way when the
ancestry chain contains merges with other git-svn branches.

Since git-svn now always uses 'git-log --first-parent' there is no longer
any need for the --first-parent option to git-svn, so this is removed.

38c9c9b798 archive: rename attribute specfile to export-subst
As suggested by Junio and Johannes, change the name of the former
attribute specfile to export-subst to indicate its function rather
than purpose and to make clear that it is not applied to working tree
files.

df4a394f91 archive: specfile syntax change: "$Format:%PLCHLDR$" instead of just "%PLCHLDR" (take 2)
As suggested by Johannes, --pretty=format: placeholders in specfiles
need to be wrapped in $Format:...$ now.  This syntax change restricts
the expansion of placeholders and makes it easier to use with files
that contain non-placeholder percent signs.

b21b9f1de3 add memmem()
memmem() is a nice GNU extension for searching a length limited string
in another one.

This compat version is based on the version found in glibc 2.2 (GPL 2);
I only removed the optimization of checking the first char by hand, and
generally tried to keep the code simple.  We can add it back if memcmp
shows up high in a profile, but for now I prefer to keep it (almost
trivially) simple.

Since I don't really know which platforms beside those with a glibc
have their own memmem(), I used a heuristic: if NO_STRCASESTR is set,
then NO_MEMMEM is set, too.

d4bb43ee27 Invoke "git gc --auto" from commit, merge, am and rebase.
The point of auto gc is to pack new objects created in loose
format, so a good rule of thumb is where we do update-ref after
creating a new commit.
