c80d25dbce 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.

9ec398d200 Fix racy-git handling in git-write-tree.
After git-write-tree finishes computing the tree, it updates the
index so that later operations can take advantage of fully
populated cache tree.

However, anybody writing the index file has to mark the entries
that are racily clean.  For each entry whose cached lstat(3)
data in the index exactly matches what is obtained from the
filesystem, if the timestamp on the index file was the same or
older than the modification timestamp of the file, the blob
contents and the work tree file, after convert_to_git(), need to
be compared, and if they are different, its index entry needs to
be marked not to match the lstat(3) data from the filesystem.

In order for this to work, convert_to_git() needs to work
correctly, which in turn means you need to read the config file
to get the settings of core.crlf and friends.

9c9f5fa97f git-gui: Do not offer to stage three-way diff hunks into the index
git-apply does not accept a patch that was generated as a three-way
combined diff format such as we see during merge conflicts.  If we
get such a diff in our diff viewer and try to send it to git-apply
it just errors out and the user is left confused wondering why they
cannot stage that hunk.

Instead of feeding a known to be unacceptable hunk to git-apply we
now just disable the stage/unstage context menu option if the hunk
came from a three way diff.  The user may still be confused about
why they cannot work with a combined diff, but at least they are
only confused as to why git-gui is not offering them the action.

8fa0ee3b50 Suggest unsetting core.bare when using new-workdir on a bare repository
If core.bare is set to true in the config file of a repository that
the user is trying to create a working directory from we should
abort and suggest to the user that they remove the option first.

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
workdirs to act as though they are not bare.

e301bfeea1 Fix new-workdir (again) to work on bare repositories
My day-job workflow involves using multiple workdirs attached to a
bunch of bare repositories.  Such repositories are stored inside of
a directory called "foo.git", which means `git rev-parse --git-dir`
will return "." and not ".git".  Under such conditions new-workdir
was getting confused about where the Git repository it was supplied
is actually located.

If we get "." for the result of --git-dir query it means we should
use the user supplied path as-is, and not attempt to perform any
magic on it, as the path is directly to the repository.

875b7c9368 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
"built" our lib/tclIndex just lists all of our library files and
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
loaded.  Since error_popup is defined in the library we instead use
tk_messageBox directly for errors found during the version detection.

ce015c213f 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).

18a01a0da4 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
need to pass off the ref name and not the SHA-1 ID.

The --walk-reflogs logic and the --reverse logic are completely
incompatible with one another.  Attempting to use both at the same
time leads to confusing results that sometimes violates the user's
formatting options or ignores the user's request to see the reflog
message and timestamp.

Unfortunately the implementation of both of these features is glued
onto the side of the revision walking machinary in such a way that
they are probably not going to be easy to make them compatible with
each other.  Rather than offering the user confusing results we are
better off bailing out with an error message until such a time as
the implementations can be refactored to be compatible.

By default 'git reflog show' will show the reflog of 'HEAD' and not

work done a while ago as part of the detached HEAD series to allow
HEAD to have its own reflog independent of each branch's reflog.

Since 'git reflog show' is really just an obscure alias for 'git

Subject: [PATCH] fastimport: Fix re-use of va_list

The va_list is designed to be used only once. The current code
reuses va_list argument may cause segmentation fault.  Copy and
release the arguments to avoid this problem.

While we are at it, fix old-style function declaration of
skip_optional_lf().

904b194151 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.

8acb3297f3 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.
