53eda89b2f merge-base: teach "git merge-base" to drive underlying merge_bases_many()
Even though the underlying function for get_merge_bases() can compute
a merge base between one existing commit and another (possibly
nonexistent) commit that would be created by merging many commits,
the facility was not available to git-merge-base.

5fc6edab76 git-gui (Windows): Change wrapper to execdir 'libexec/git-core'
git-gui needs bindir in PATH to be able to run 'git'.  bindir
however is not necessarily in PATH if started directly through a
Windows shortcut.  Therefore, we used to add the directory
git-gui is located in.  But with the new 'libexec/git-core'
layout this directory is no longer identical to bindir.

This commit modifies the wrapper script to discover the bindir
and add it to PATH.

f8f1acf339 git-gui: Correct installation of library to be $prefix/share
We always wanted the library for git-gui to install into the
$prefix/share directory, not $prefix/libexec/share.  All of
the files in our library are platform independent and may
be reused across systems, like any other content stored in
the share directory.

Our computation of where our library should install to was broken
when git itself started installing to $prefix/libexec/git-core,
which was one level down from where we expected it to be.

79317e5df1 git-gui: Fix gitk search in $PATH to work on Windows
Back in 15430be5a1 ("Look for gitk in $PATH, not $LIBEXEC/git-core")
git-gui learned to use [_which gitk] to locate where gitk's script
is as Git 1.6 will install gitk to $prefix/bin (in $PATH) and all
of the other tools are in $gitexecdir.

This failed on Windows because _which adds the ".exe" suffix as it
searches for the program on $PATH, under the assumption that we can
only execute something from Tcl if it is a proper Windows executable.

When scanning for gitk on Windows we need to omit the ".exe" suffix.

A new configuration variable 'core.trustctime' is introduced to
allow ignoring st_ctime information when checking if paths

it produces too much false positives.  Like when file system crawlers
keep changing it when scanning and using the ctime for marking scanned

Before this patch "git merge-base" just exited with error code 1
and without an error message in case it was passed a ref to an

65c35b2256 t7001: fix "git mv" test
The test assumed that we can keep the cached stat information fresh across
rename(2); many filesystems however update st_ctime (and POSIX allows them
to do so), and that assumption does not hold.

172035f044 init: handle empty "template" parameter
If a user passes "--template=", then our template parameter
is blank. Unfortunately, copy_templates() assumes it has at
least one character, and does all sorts of bad things like
reading from template[-1] and then proceeding to link all of
'/' into the .git directory.

This patch just checks for that condition in copy_templates
and aborts. As a side effect, this means that --template=

81dc2307d0 git-mv: Keep moved index entries inact
The rewrite of git-mv from a shell script to a builtin was perhaps
a little too straightforward: the git add and git rm queues were
emulated directly, which resulted in a rather complicated code and
caused an inconsistent behaviour when moving dirty index entries;
git mv would update the entry based on working tree state,
except in case of overwrites, where the new entry would still have
sha1 of the old file.

This patch introduces rename_index_entry_at() into the index toolkit,
which will rename an entry while removing any entries the new entry
might render duplicate. This is then used in git mv instead
of all the file queues, resulting in a major simplification
of the code and an inevitable change in git mv -n output format.

Also the code used to refuse renaming overwriting symlink with a regular
file and vice versa; there is no need for that.

A few new tests have been added to the testsuite to reflect this change.

f6c52fe4e8 git-mv: Remove dead code branch
The path list builder had a branch for the case the source is not in index, but
this can happen only if the source was a directory. However, in that case we
have already expanded the list to the directory contents and set mode
to WORKING_DIRECTORY, which is tested earlier.

The patch removes the superfluous branch and adds an assert() instead. git-mv
testsuite still passes.

a08c53a119 fsck: Don't require tmp_obj_ file names are 14 bytes in length
Not all temporary file creation routines will ensure 14 bytes are
used to generate the temporary file name.  In C Git this may be
true, but alternate implementations such as jgit are not always
able to generate a temporary file name with a specific prefix and
also ensure the file name length is 14 bytes long.

Since temporary files in a directory we are fsck'ing should be
uncommon (as they are short lived only long enough for an active
writer to finish writing the file and rename it) we shouldn't see
these show up very often.  Always using a prefixcmp() call and
ignoring the length opens up room for other implementations to use
different name generation schemes.

to the directory which entries it listed, so that the check if the
file is executable could be done on dir->d_name.

However, there is no good reason to jump around wildly just to find
all Git commands.

Instead, have a strbuf and construct the full path dynamically.

47c6ef1c8d make sure parsed wildcard refspec ends with slash
A wildcard refspec is internally parsed into a refspec structure with src
and dst strings.  Many parts of the code assumed that these do not include
the trailing "/*" when matching the wildcard pattern with an actual ref we
see at the remote.  What this meant was that we needed to make sure not
just that the prefix matched, and also that a slash followed the part that
matched.

But a codepath that scans the result from ls-remote and finds matching
refs forgot to check the "matching part must be followed by a slash" rule.
This resulted in "refs/heads/b1" from the remote side to mistakenly match
the source side of "refs/heads/b/*:refs/remotes/b/*" refspec.

Worse, the refspec crafted internally by "git-clone", and a hardcoded
preparsed refspec that is used to implement "git-fetch --tags", violated
this "parsed widcard refspec does not end with slash" rule; simply adding
the "matching part must be followed by a slash" rule then would have
broken codepaths that use these refspecs.

This commit changes the rule to require a trailing slash to parsed
wildcard refspecs.  IOW, "refs/heads/b/*:refs/remotes/b/*" is parsed as
src = "refs/heads/b/" and dst = "refs/remotes/b/".  This allows us to
simplify the matching logic because we only need to do a prefixcmp() to
notice "refs/heads/b/one" matches and "refs/heads/b1" does not.

c7f7457026 git-gui: "Stage Line": Treat independent changes in adjacent lines better

  old 1                new 1                new 1
  old 2                old 2                new 2
  context after        context after        context after

that is, want to commit two changes in this order:

  1. transform "old 1" into "new 1"
  2. transform "old 2" into "new 2"

[This discussion and this patch is about this very case and one other case
as outlined below; any other intermediate states that one could imagine are
not affected by this patch.]

Now assume further, that we have not staged and commited anything, but we
have already changed the working file to the new state. Then we will see
this hunk in the "Unstaged Changes":

  @@ -1,4 +1,4 @@
   context before
  -old 1
  -old 2
  +new 1
  +new 2
   context after

The obvious way to stage the intermediate state is to apply "Stage This
Line" to "-old 1" and "+new 1". Unfortunately, this resulted in this
intermediate state:

  context before
  old 2
  new 1
  context after

which is not what we wanted. In fact, it was impossible to stage the
intermediate state using "Stage Line". The crux was that if a "+" line was
staged, then the "-" lines were converted to context lines and arranged
*before* the "+" line in the forged hunk that we fed to 'git apply'.

With this patch we now treat "+" lines that are staged differently. In
particular, the "-" lines before the "+" block are moved *after* the
staged "+" line. Now it is possible to get the correct intermediate state
by staging "-old 1" and "+new 1". Problem solved.

But there is a catch.

Noticing that we didn't get the right intermediate state by staging
"-old 1" and "+new 1", we could have had the idea to stage the complete
hunk and to *unstage* "-old 2" and "+new 2". But... the result is the same.
The reason is that there is the exact symmetric problem with unstaging the
last "-" and "+" line that are in adjacent blocks of "-" and "+" lines.

This patch does *not* change the way in which "-" lines are *unstaged*.

Why? Because if we did (i.e. move "+" lines before the "-" line after
converting them to context lines), then it would be impossible to stage
this intermediate state:

  context before
  old 1
  new 2
  context after

that is, it would be impossible to stage the two independet changes in the
opposite order.

Let's look at this case a bit further: The obvious way to get this
intermediate state would be to apply "Stage This Line" to "-old 2" and
"+new 2". Before this patch, this worked as expected. With this patch, it
does not work as expected, but it can still be achieved by first staging
the entire hunk, then *unstaging* "-old 1" and "+new 1".

In summary, this patch makes a common case possible, at the expense that
a less common case is made more complicated for the user.

9f1ad541f9 imap-send.c: more style fixes
The previous one sqeezed unnecessary whitespaces and joined function type
and name in the definition split across lines.  This patch further fixes
many remaining style issues:

 - We are not particularly fond of typedef to hide the underlying struct
   definitions.

 - Asterisk comes next variable, i.e. "type *var", not "type * var" nor
   "type* var".

 - Casting to pointer to a type is "(type *)", not "(type*)".

 - An open brace comes on the same line as closing parenthesis of "if (...)"
   condition; "else" comes on the same line as closing brace of its
   corresponding "if (...) {".

 - Avoid single liner "if (...) <stmt>;"; they should be on two separate
   lines.

684ec6c63c git-imap-send: Support SSL
Allow SSL to be used when a imaps:// URL is used for the host name.

Also, automatically use TLS when not using imaps:// by using the IMAP
STARTTLS command, if the server supports it.

Tested with Courier and Gimap IMAP servers.

ea27a18ce2 spawn pager via run_command interface
This has two important effects:

 1. The pager is now the _child_ process, instead of the
    parent. This means that whatever spawned git (e.g., the
    shell) will see the exit code of the git process, and
    not the pager.

 2. The mingw and regular code are now unified, which makes
    the setup_pager function much simpler.

There are two caveats:

 1. We used to call execlp directly on the pager, followed
    by trying to exec it via the shall. We now just use the
    shell (which is what mingw has always done). This may
    have different results for pager names which contain
    shell metacharacters.

    It is also slightly less efficient because we
    unnecessarily run the shell; however, pager spawning is
    by definition an interactive task, so it shouldn't be
    a huge problem.

 2. The git process will remain in memory while the user
    looks through the pager. This is potentially wasteful.
    We could get around this by turning the parent into a
    meta-process which spawns _both_ git and the pager,
    collects the exit status from git, waits for both to
    end, and then exits with git's exit code.

ccf08bc3d0 run-command: add pre-exec callback
This is a function provided by the caller which is called
_after_ the process is forked, but before the spawned
program is executed. On platforms (like mingw) where
subprocesses are forked and executed in a single call, the
preexec callback is simply ignored.

This will be used in the following patch to do some setup
for 'less' that must happen in the forked child.

1e5f764c93 builtin-add.c: optimize -A option and "git add ."
The earlier "git add -A" change was done in a quite inefficient
way (i.e. it is as unefficient as "git add -u && git add ." modulo
one fork/exec and read/write index).

When the user asks "git add .", we do not have to examine all paths
we encounter and perform the excluded() and dir_add_name()
processing, both of which are slower code and use slower data structure
by git standards, especially when the index is already populated.

Instead, we implement "git add $pathspec..." as:

 - read the index;

 - read_directory() to process untracked, unignored files the current
   way, that is, recursively doing readdir(), filtering them by pathspec
   and excluded(), queueing them via dir_add_name() and finally do
   add_files(); and

 - iterate over the index, filtering them by pathspec, and update only
   the modified/type changed paths but not deleted ones.

And "git add -A" becomes exactly the same as above, modulo:

 - missing $pathspec means "." instead of being an error; and

 - "iterate over the index" part handles deleted ones as well,
   i.e. exactly what the current update_callback() in builtin-add.c does.

In either case, because fill_directory() does not use read_directory() to
read everything in, we need to add an extra logic to iterate over the
index to catch mistyped pathspec.

041aee31be builtin-add.c: restructure the code for maintainability
A private function add_files_to_cache() in builtin-add.c was borrowed by
checkout and commit re-implementors without getting properly refactored to
more library-ish place.  This does the refactoring.
