gitweb: Remove parse_from_to_diffinfo code from git_patchset_body
In commit 90921740bd00029708370673fdc537522aa48e6f
"gitweb: Split git_patchset_body into separate subroutines"
a part of git_patchset_body code was separated into parse_from_to_diffinfo
subroutine. But instead of replacing the separated code by the call to
mentioned subroutine, the call to subroutine was placed before the separated
code. This patch removes parse_from_to_diffinfo code from git_patchset_body
subroutine.

A lot of shell scripts contained stuff starting with
while case "$#" in 0) break ;; esac
and similar. I consider breaking out of the condition instead of the
body od the loop ugly, and the implied "true" value of the
non-matching case is not really obvious to humans at first glance. It
happens not to be obvious to some BSD shells, either, but that's
because they are not POSIX-compliant. In most cases, this has been
replaced by a straight condition using "test". "case" has the
advantage of being faster than "test" on vintage shells where "test"
is not a builtin. Since none of them is likely to run the git
scripts, anyway, the added readability should be worth the change.
A few loops have had their termination condition expressed
differently.

Documentation/git-lost-found.txt: drop unnecessarily duplicated name.
I only did this back when I wanted to make sure git-log and gitk work
properly with non Occidental characters. There is really no reason to
keep it around.
The example provided with the update-hook-example does not work on
either bash 2.05b.0(1)-release nor 3.1.17(1)-release. The matcher did
not match the lines that it advertised to match, such as:
refs/heads/bw/ linus
refs/heads/tmp/* *
In POSIX 1003.2 regular expressions, the star (*), is not an wildcard
meaning "match everything", it matches 0 or more matches of the atom
preceding it.
So to match "refs/heads/bw/topic-branch", the matcher should be written
as "refs/heads/bw/.*" to match "refs/heads/bw/" and everything after it.

git-commit: partial commit of paths only removed from the index
Because a partial commit is meant to be a way to ignore what are
staged in the index, "git rm --cached A && git commit A" should
just record what is in A on the filesystem. The previous patch
made the command sequence to barf, saying that A has not been
added yet. This fixes it.
When making a partial commit, git-commit uses git-ls-files with
the --error-unmatch option to expand and sanity check the user
supplied path patterns. When any path pattern does not match
with the paths known to the index, it errors out, in order to
catch a common mistake to say "git commit Makefiel cache.h"
and end up with a commit that touches only cache.h (notice the
misspelled "Makefile"). This detection however does not work
well when the path has already been removed from the index.
If you drop a path from the index and try to commit that
partially, i.e.
the command complains because git does not know anything about
COPYING anymore.
This introduces a new option --with-tree to git-ls-files and
uses it in git-commit when we build a temporary index to
write a tree object for the partial commit.
When --with-tree=<tree-ish> option is specified, names from the
given tree are added to the set of names the index knows about,
so we can treat COPYING file in the example as known.
Of course, there is no reason to use "git rm" and git-aware
people have long time done:

send-email: make message-id generation a bit more robust
Earlier code took Unix time and appended a few random digits.
If you are firing off many messages within a second, you could
issue the same id to different messages, which is a no-no. If
you send out 31 messages within a single second, with random
integer taken out of rand(4200), you have about 10% chance of
producing the same message ID.
This fixes the problem by uses a prefix string which is
constant-per-invocation (time and pid), with a serial number for
each message generated by the process appended at the end.
git-gui: Disable native platform text selection in "lists"
Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.
In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings. In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget. Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.
Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text. So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

revision walker: --cherry-pick is a limited operation
We used to rely on the fact that cherry-pick would trigger the code path
to set limited = 1 in handle_commit(), when an uninteresting commit was
encountered.
However, when cherry picking between two independent branches, i.e. when
there are no merge bases, and there is only linear development (which can
happen when you cvsimport a fork of a project), no uninteresting commit
will be encountered.
So set limited = 1 when --cherry-pick was asked for.

Split grep arguments in a way that does not requires to add /dev/null.
In order to (almost) always show the name of the file without
relying on "-H" option of GNU grep, we used to add /dev/null to
the argument list unless we are doing -l or -L. This caused
"/dev/null:0" to show up when -c is given in the output.
It is not enough to add -c to the set of options we do not pass
/dev/null for. When we have too many files, we invoke grep
multiple times and we need to avoid giving a widow filename to
the last invocation -- otherwise we will not see the name.
This keeps two filenames when the argv[] buffer is about to
overflow and we have not finished iterating over the index, so
that the last round will always have at least two paths to work
with (and not require /dev/null).
An obvious and the only exception is when there is only 1 file
that is given to the underlying grep, and in that case we avoid
passing /dev/null and let the external "grep -c" report only the
number of matches.

This adds more proper rename detection limits. Instead of just checking
the limit against the number of potential rename destinations, we verify
that the rename matrix (which is what really matters) doesn't grow
ridiculously large, and we also make sure that we don't overflow when
doing the matrix size calculation.
This also changes the default limits from unlimited, to a rename matrix
that is limited to 100 entries on a side. You can raise it with the config
entry, or by using the "-l<n>" command line flag, but at least the default
is now a sane number that avoids spending lots of time (and memory) in
situations that likely don't merit it.
The choice of default value is of course very debatable. Limiting the
rename matrix to a 100x100 size will mean that even if you have just one
obvious rename, but you also create (or delete) 10,000 files, the rename
matrix will be so big that we disable the heuristics. Sounds reasonable to
me, but let's see if people hit this (and, perhaps more importantly,
actually *care*) in real life.

We currently assume that the complete set of files we need to delete

This could differ from what the user actually has installed if they

git-gui: Font chooser to handle a large number of font families
Simon Sasburg noticed that on X11 if there are more fonts than can

offer scroll arrows to the user and it is not possible to review
all choices or to select those that are off-screen. On Mac OS X
the tk_optionMenu works properly but is awkward to navigate if the
list is long.
This is a rewrite of our font selection by providing a new modal
dialog that the user can launch from the git-gui Options panel.
The dialog offers the user a scrolling list of fonts in a pane.
An example text shows the user what the font looks like at the size
they have selected. But I have to admit the example pane is less
than ideal. For example in the case of our diff font we really
should show the user an example diff complete with our native diff
syntax coloring.

On filesystems where it is appropriate to set core.filemode

A fix requires noting the new file execute permission in the

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.

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.

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

git-new-workdir a b
...
git-new-workdir a b
by accident will cause a (and now also b) to have an infinite cycle
in its refs directory. This is caused by git-new-workdir trying
to create the "refs" symlink over again, only during the second
time it is being created within a's refs directory and is now also
pointing back at a's refs.
This causes confusion in git as suddenly branches are named things
like "refs/refs/refs/refs/refs/refs/refs/heads/foo" instead of the
more commonly accepted "refs/heads/foo". Plenty of commands start
to see ambiguous ref names and others just take ages to compute.
git-clone has the same safety check, so git-new-workdir should
behave just like it.

When the preimage we are patching is shorter than what the patch
text expects, we tried to match the buffer contents at the
"original" line with the fragment in full, without checking we
have enough data to match in the preimage. This caused the size
of a later memmove() to wrap around and attempt to scribble
almost the entire address space. Not good.
The code that follows the part this patch touches tries to match
the fragment with line offsets. Curiously, that code does not
have the problem --- it guards against reading past the end of
the preimage.
git-gui: Properly set the state of "Stage/Unstage Hunk" action
Today I found yet another way for the "Stage Hunk" and "Unstage
Hunk" context menu actions to leave the wrong state enabled in
the UI. The problem this time was that I connected the state
determination to the value of $::current_diff_side (the side the
diff is from). When the user was last looking at a diff from the
index side and unstages everything the diff panel goes empty, but
the action stayed enabled as we always assumed unstaging was a
valid action.
This change moves the logic for determining when the action is
enabled away from the individual side selection, as they really
are two unrelated concepts.

git-gui: Fix detaching current branch during checkout
If the user tried to detach their HEAD while keeping the working
directory on the same commit we actually did not completely do
a detach operation internally. The problem was caused by git-gui
not forcing the HEAD symbolic ref to be updated to a SHA-1 hash
when we were not switching revisions. Now we update the HEAD ref
if we aren't currently detached or the hashes don't match.

git-gui: Correct starting of git-remote to handle -w option
Current versions of git-remote apparently are passing the -w option
to Perl as part of the shbang line:
#!/usr/bin/perl -w
this caused a problem in git-gui and gave the user a Tcl error with
the message: "git-remote not supported: #!/usr/bin/perl -w".
The fix for this is to treat the shbang line as a Tcl list and look
at the first element only for guessing the executable name. Once
we know the executable name we use the remaining elements (if any
exist) as arguments to the executable, before the script filename.

HPA noticed that yum does not like the newer git RPM set; it turns out
that we do not ship git-p4 anymore but existing installations do not
realize the package is gone if we do not tell anything about it.
David Kastrup suggests using Obsoletes in the spec file of the new
RPM to replace the old package, so here is a try.
