This clarifies the logic to omit fast-forward check and omit
trivial merge before running the specified strategy.
The "index_merge" variable started out as a flag to say "do not
do anything clever", but when recursive was changed to skip the
trivial merge, the semantics were changed and the variable alone
does not make sense anymore.
This splits the variable into two, allow_fast_forward (which is
almost always true, and avoids making a merge commit when the
other commit is a descendant of our branch, but is set to false
for ours and subtree) and allow_trivial_merge (which is false
for ours, recursive and subtree).
Unlike the earlier implementation, the "ours" strategy allows an
up-to-date condition. When we are up-to-date, the result will
be our commit, and by definition, we will have our tree as the
result.

"GIT_DIR=some.where git --bare cmd" and worse yet
"git --git-dir=some.where --bare cmd" were very confusing. They
both ignored git-dir specified, and instead made $cwd as GIT_DIR.
This changes --bare not to override existing GIT_DIR.
This has been like this for a long time. Let's hope nobody sane
relied on this insane behaviour.

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.

Uwe Kleine-König noticed that under certain circumstances, name-rev
picked a non-optimal tag. Jeff King analyzed that name-rev only
takes into account the number of merge traversals, and then the
_last_ number in the description.
As an easy way to fix it, use a weighting factor for merge traversals:
A merge traversal is now made 65535 times more expensive than a

The immediate motivation for writing this section was to explain the
various places ignore patterns could be used. However, I still think
.gitignore is the case most people will want to learn about first. It
also makes it a bit more concrete to introduce ignore patterns in the
context of .gitignore first. And the existance of gitignore(5) relieves
the pressure to explain it all here.
So, stick to the .gitignore example, with only a brief mention of the
others, explain the syntax only by example, and leave the rest to
gitignore(5).

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
the delta unpacking code, we better handle it correctly.

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.

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.

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.

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.
