gitweb: No difftree output for trivial merge

In 'commitdiff' view, for the merge commit, there is an extra header
for the difftree table, with links to commitdiffs to individual
parents. Do not show such header when there is nothing to show, for
trivial merges.

This means that for trivial merge you have to go to 'commit' view
to get links to diffs to each parent.

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.

git-merge: add support for --commit and --no-squash

These options can be used to override --no-commit and --squash, which is
needed since --no-commit and --squash now can be specified as default merge
options in $GIT_DIR/config.

The change also introduces slightly different behavior for --no-commit:
when specified, it explicitly overrides --squash. Earlier,
'git merge --squash --no-commit' would result in a squashed merge (i.e. no
$GIT_DIR/MERGE_HEAD was created) but with this patch the command will
behave as if --squash hadn't been specified.

Supplant the "while case ... break ;; esac" idiom

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 In most cases, this has been
replaced by a straight condition using "test".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.

git-svn: handle changed svn command-line syntax

Previously, if you passed a revision and a path to svn cp, it meant to look
back at that revision and select that path. New behaviour is to get the
path then go back to the revision (like other commands that accept @REV
or -rREV do). The more consistent syntax is not supported by the old
tools, so we have to try both in turn.

Full rework of quote_c_style and write_name_quoted.Pierre Habouzit Wed, 19 Sep 2007 22:42:15 +0000 (00:42 +0200)

Full rework of quote_c_style and write_name_quoted.

* quote_c_style works on a strbuf instead of a wild buffer.
* quote_c_style is now clever enough to not add double quotes if not needed.

* write_name_quoted inherits those advantages, but also take a different
set of arguments. Now instead of asking for quotes or not, you pass a
"terminator". If it's \0 then we assume you don't want to escape, else C
escaping is performed. In any case, the terminator is also appended to the
stream. It also no longer takes the prefix/prefix_len arguments, as it's
seldomly used, and makes some optimizations harder.

* write_name_quotedpfx is created to work like write_name_quoted and take
the prefix/prefix_len arguments.

Thanks to those API changes, diff.c has somehow lost weight, thanks to the
removal of functions that were wrappers around the old write_name_quoted
trying to give it a semantics like the new one, but performing a lot of
allocations for this goal. Now we always write directly to the stream, no
intermediate allocation is performed.

As a side effect of the refactor in builtin-apply.c, the length of the bar
graphs in diffstats are not affected anymore by the fact that the path was
clipped.

Rework unquote_c_style to work on a strbuf.

If the gain is not obvious in the diffstat, the resulting code is more
readable, _and_ in checkout-index/update-index we now reuse the same buffer
to unquote strings instead of always freeing/mallocing.

This also is more coherent with the next patch that reworks quoting
functions.

The quoting function is also made more efficient scanning for backslashes
and treating portions of strings without a backslash at once.

apply: get rid of --index-info in favor of --build-fake-ancestor

git-am used "git apply -z --index-info" to find the original versions
of the files touched by the diff, to be able to do an inexpensive
three-way merge.

This operation makes only sense in a repository, since the index
information in the diff refers to blobs, which have to be present in
the current repository.

Therefore, teach "git apply" a mode to write out the result as an
index file to begin with, obviating the need for scripts to do it
themselves.

The sole user for --index-info is "git am" is converted to
use --build-fake-ancestor in this patch.

Added example hook script to save/restore permissions... Josh England Tue, 11 Sep 2007 16:59:04 +0000 (10:59 -0600)

Added example hook script to save/restore permissions/ownership.

Usage info is emebed in the script, but the gist of it is to run the script
from a pre-commit hook to save permissions/ownership data to a file and check
that file into the repository. Then, a post_merge hook reads the file and
updates working tree permissions/ownership. All updates are transparent to
the user (although there is a --verbose option). Merge conflicts are handled
in the "read" phase (in pre-commit), and the script aborts the commit and
tells you how to fix things in the case of a merge conflict in the metadata
file. This same idea could be extended to handle file ACLs or other file
metadata if desired.

not match the lines that it advertised to match, such as:

refs/heads/bw/ linus

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.

Drop strbuf's 'eof' marker, and make read_line a first class citizen.

read_line is now strbuf_getline, and is a first class citizen, it returns 0
when reading a line worked, EOF else.

The ->eof marker was used non-locally by fast-import.c, mimic the same
behaviour using a static int in "read_next_command", that now returns -1 on
EOF, and avoids to call strbuf_getline when it's in EOF state.

Also no longer automagically strbuf_release the buffer, it's counter
intuitive and breaks fast-import in a very subtle way.

Note: being at EOF implies that command_buf.len == 0.

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.

git-commit: Allow partial commit of file removal.Junio C Hamano Wed, 12 Sep 2007 23:04:22 +0000 (16:04 -0700)

git-commit: Allow partial commit of file removal.

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.

$ git rm COPYING
$ git commit -m 'Remove COPYING' COPYING

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:

$ rm COPYING
$ git commit -m 'Remove COPYING' COPYING

which works just fine. But this caused a constant confusion.

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.

Rewrite convert_to_{git,working_tree} to use strbuf's.

* Now, those functions take an "out" strbuf argument, where they store their

* those functions support "in place" editing, in the sense that it's OK to
call them this way:
convert_to_git(path, sb->buf, sb->len, sb);
When doable, conversions are done in place for real, else the strbuf
content is just replaced with the new one, transparentely for the caller.

If you want to create a new filter working this way, being the accumulation
of filter1, filter2, ... filtern, then your meta_filter would be:

int meta_filter(..., const char *src, size_t len, struct strbuf *sb)
{
int ret = 0;
ret |= filter1(...., src, len, sb);
if (ret) {
src = sb->buf;
len = sb->len;
}
ret |= filter2(...., src, len, sb);
if (ret) {
src = sb->buf;
len = sb->len;
}
....
return ret | filtern(..., src, len, sb);
}

documentation: replace Discussion section by link to user-manual chapter

The "Discussion" section has a lot of useful information, but is a
little wordy, especially for an already-long man page, and is designed
for an audience more of potential git hackers than users, which probably
doesn't make as much sense as git matures. Also, I (perhaps foolishly)
forked a version in the user manual, which has been significantly
rewritten in an attempt to address some of the above problems.

So, remove this section and replace it by a (very terse) summary of the
original material--my attempt at the World's Shortest Git Overview--and
a reference to the appropriate chapter of the user manual. It's
unfortunate to remove something that's been in this place for a long
time, as some people may still depend on finding it there. But I think
we'll want to do this some day anyway.

user-manual: todo updates and cleanup

Format a couple lists. Reminder that we may want to add submodule
documentation some day.

user-manual: fix introduction to packfiles

Actually I don't think we've previously mentioned .git/objects, so we
need a different introduction here.

user-manual: move packfile and dangling object discussion

The discussions of packfiles and dangling objects both belong in the
object database section.

user-manual: rewrite object database discussionJ. Bruce Fields Sun, 10 Jun 2007 19:15:08 +0000 (15:15 -0400)

user-manual: rewrite object database discussion

Rewrite the introduction. Rewrite each section completely to make them
work in the new order, to add some examples, and to move plumbing
commands (like git-commit-tree) to the following chapter.

user-manual: reorder commit, blob, tree discussion

The bottom-up blog, tree, commit order makes sense unless you want to
give explicit examples--it's easier to discover objects to examine if
you go in the other order....,

user-manual: rewrite index discussionJ. Bruce Fields Mon, 3 Sep 2007 16:59:55 +0000 (12:59 -0400)

user-manual: rewrite index discussion

Add an example using git-ls-files, standardize on the new "index"
terminology (as opposed to "cache"), attempt to clarify discussion and
make it a little shorter, avoid some unnecessary jargon ("write-back
cache").

user-manual: create new "low-level git operations" chapter

The low-level index operations aren't as important to regular users as
the rest of this "git concepts" chapter; so move it into a separate
chapter, and do some minor cleanup.

user-manual: rename "git internals" to "git concepts"J. Bruce Fields Fri, 31 Aug 2007 03:10:05 +0000 (23:10 -0400)

user-manual: rename "git internals" to "git concepts"

"git internals" sounds like something only git developers must know
about, but this stuff should be of wider interest. Rename the chapter
and give it a slightly friendlier introduction.

user-manual: move object format details to hacking-git chapter

Most of this is probably only of interest to git developers.
