Fix initialization of a bare repository
Here is my attempt to fix this with a minimally intrusive patch.
* As "git --bare init" cannot tell if it was called with --bare or
just "GIT_DIR=. git init", I added an explicit assignment of
is_bare_repository_cfg on the codepath for "git --bare".
* GIT_WORK_TREE alone without GIT_DIR does not make any sense,
nor GIT_WORK_TREE with an explicit "git --bare". Catch that
mistake. It might make sense to move this check to "git.c"
side as well, but I tried to shoot for the minimum change for
now.
* Some scripts, especially from the olden days, rely on
traditional GIT_DIR behaviour in "git init". Namely, these
are some notable patterns:
(create a bare repository)
- mkdir some.git && cd some.git && GIT_DIR=. git init
- mkdir some.git && cd some.git && git --bare init
(create a non-bare repository)
- mkdir .git && GIT_DIR=.git git init
- mkdir .git && GIT_DIR=`pwd`/.git git init
This comes with a new test script and also passes the existing
test suite, but there may be cases that are still broken with
the current tip of master and this patch does not yet fix. I'd
appreciate help in straightening this mess out.

Don't segfault if we failed to inflate a packed delta
Under some types of packfile corruption the zlib stream holding the
data for a delta within a packfile may fail to inflate, due to say
a CRC failure within the compressed data itself. When this occurs
the unpack_compressed_entry function will return NULL as a signal to
the caller that the data is not available. Unfortunately we then
tried to use that NULL as though it referenced a memory location
where a delta was stored and tried to apply it to the delta base.
Loading a byte from the NULL address typically causes a SIGSEGV.
cate on #git noticed this failure in `git fsck --full` where the
call to verify_pack() first noticed that the packfile was corrupt
by finding that the packfile's SHA-1 did not match the raw data of
the file. After finding this fsck went ahead and tried to verify
every object within the packfile, even though the packfile was
already known to be bad. If we are going to shovel bad data at

git-gui: Correct 'git gui blame' in a subdirectory
David Kastrup pointed out that the following sequence was not
working as we had intended:
$ cd lib
$ git gui blame console.tcl
fatal: cannot stat path lib/console.tcl: No such file or directory
The problem here was we disabled the chdir to the root of the
working tree when we are running with a "bare allowed" feature
such as blame or browser, but we still kept the prefix we found via
`git rev-parse --show-prefix`. This caused us to try and look for
the file "console.tcl" within the subdirectory but also include
the subdirectory's own path from the root of the working tree.
This is unlikely to succeed, unless the user just happened to have
a "lib/lib/console.tcl" file in the repository, in which case we
would produce the wrong result.
In the case of a bare repository we shouldn't get back a value from
`rev-parse --show-prefix`, so really $_prefix should only be set
to the non-empty string if we are in a working tree and we are in a
subdirectory of that working tree. If this is true we really want
to always be at the top level of the working tree, as all paths are
accessed as though they were relative to the top of the working tree.
Converting $_prefix to a ../ sequence is a fairly simple approach
to moving up the requisite levels.

Suggest unsetting core.bare when using new-workdir on a bare repository

the user is trying to create a working directory from we should

If we leave the core.bare=true setting in the config file then
working tree operations will get confused when they attempt to
execute in the new workdir, as it shares its config file with the
bare repository. The working tree operations will assume that the
workdir is bare and abort, which is not what the user wants.
If we changed core.bare to be false then working tree operations
will function in the workdir but other operations may fail in the
bare repository, as it claims to not be bare.
If we remove core.bare from the config then Git can fallback on
the legacy guessing behavior. This allows operations in the bare
repository to work as though it were bare, while operations in the

git-gui: Fix "unoptimized loading" to not cause git-gui to crash
If the tclsh command was not available to us at the time we were

we source all of them at once during startup, rather than trying
to lazily load only the procedures we need. This is a problem as
some of our library code now depends upon the git-version proc,
and that proc is not defined until after the library was fully
loaded.
I'm moving the library loading until after we have determined the
version of git we are talking to, as this ensures that the required
git-reversion procedure is defined before any library code can be

git-gui: Paper bag fix "Stage Hunk For Commit" in diff context menu
In
a13ee29b975d3a9a012983309e842d942b2bbd44 I totally broke the
"Stage Hunk For Commit" feature by making this menu item always
appear in a disabled state, so it was never invokable. A "teaser
feature", just sitting there taunting the poor user who has become
used to having it available.
The issue caused by a13ee was I added a test to look at the data
in $file_states, but I didn't do that test correctly as it was
always looking at a procedure local $file_states array, which is
not defined, so the test was always true and we always disabled
the menu entry.
Instead we only want to disable the menu entry if the current file
we are looking at has no file state information (git-gui is just a
very confused little process) or it is an untracked file (and we
cannot stage individual hunks).

git-gui: Allow git-merge to use branch names in conflict markers
Earlier when I rewrote the merge implementation for git-gui I broke
it such that the conflict markers for the "theirs" side of the hunk
was using a full SHA-1 ID in hex, rather than the name of the branch
the user had merged. This was because I got paranoid and passed off
the full SHA-1 to git-merge, instead of giving it the reference name
the user saw in the merge dialog.
I'd still like to resolve the SHA-1 upfront in git-gui and always use
that value throughout the merge, but I can't do that until we have a
full implementation of git-merge written in Tcl. Until then its more
important that the conflict markers be useful to the end-user, so we

Include recent command history in fast-import crash reports
When we crash the frontend developer (or end-user) may need to know
roughly around what part of the input stream we had a problem with
and aborted on. Because line numbers aren't very useful in this
sort of application we instead just keep the last 100 commands in
a FIFO queue and print them as part of the crash report.
Currently one problem with this design is a commit that has
more than 100 modified files in it will flood the FIFO and any
context regarding branch/from/committer/mark/comments will be lost.
We really should save only the last few (10?) file changes for the
current commit, ensuring we have some prior higher level commands
in the FIFO when we crash on a file M/D/C/R command.
Another issue with this approach is the FIFO only includes the
commands, it does not include the commit messages. Yet having a
commit message may be useful to help locate the relevant change in
the source material. In practice I don't think this is going to be a
major concern as the frontend can always embed its own source change
set identifier as a comment (which will appear in the crash report)
and the commit message(s) for the most recent commits of any given
branch should be obtainable from the (packed) commit objects.

Generate crash reports on die in fast-import
As fast-import is quite strict about its input and die()'s anytime
something goes wrong it can be difficult for a frontend developer
to troubleshoot why fast-import rejected their input, or to even
determine what input command it rejected.
This change introduces a custom handler for Git's die() routine.
When we receive a die() for any reason (fast-import or a lower level
core Git routine we called) the error is first dumped onto stderr
and then a more extensive crash report file is prepared in GIT_DIR.
Finally we exit the process with status 128, just like the stock
builtin die handler.
An internal flag is set to prevent any further die()'s that may be
invoked during the crash report generator from causing us to enter
into an infinite loop. We shouldn't die() from our crash report
handler, but just in case someone makes a future code change we are
prepared to gaurd against small mistakes turning into huge problems
for the end-user.

Make trailing LF optional for all fast-import commands
For the same reasons as the prior change we want to allow frontends
to omit the trailing LF that usually delimits commands. In some
cases these just make the input stream more verbose looking than
it needs to be, and its just simpler for the frontend developer to
get started if our parser is slightly more lenient about where an
LF is required and where it isn't.
To make this optional LF feature work we now have to buffer up to one
line of input in command_buf. This buffering can happen if we look
at the current input command but don't recognize it at this point
in the code. In such a case we need to "unget" the entire line,
but we cannot depend upon the stdio library to let us do ungetc()
for that many characters at once.

Teach fast-import to ignore lines starting with '#'
Several frontend developers have asked that some form of stream
comments be permitted within a fast-import data stream. This way
they can include information from their own frontend program about
where specific data was taken from in the source system, or about
a decision that their frontend may have made while creating the
fast-import data stream.
This change introduces comments in the Bourne-shell/Tcl/Perl style.
Lines starting with '#' are ignored, up to and including the LF.
Unlike the above mentioned three languages however we do not look for
and ignore leading whitespace. This just simplifies the definition
of the comment format and the code that parses them.
To make comments work we had to stop using read_next_command() within
cmd_data() and directly invoke read_line() during the inline variant
of the function. This is necessary to retain any lines of the
input data that might otherwise look like a comment to fast-import.

valid of a ref as HEAD and MERGE_HEAD, so we really should permit it

Fix "git add -u" data corruption.
This applies to 'maint' to fix a rather serious data corruption
issue. When "git add -u" affects a subdirectory in such a way
that the only changes to its contents are path removals, the
next tree object written out of that index was bogus, as the
remove codepath forgot to invalidate the cache-tree entry.

path-list.c: always free strdup'ed paths
Always free .paths if .strdup_paths is set, no matter if the
parameter free_items is set or not, plugging a minor memory leak.
And to clarify the meaning of the flag, rename it to free_util,
since it now only affects the freeing of the .util field.
