Stop using compat/regex.c on platforms with working regexp library

We used to have non-POSIX comformant BRE in our code, and linked with GNU
regexp library on a few platforms (Darwin, FreeBSD and AIX) to work it
around. This was backwards.

We've fixed the broken regexps to use ERE that native regexp libraries on
these platforms can handle just fine. There is no need to link with GNU
regexp library on these platforms anymore.

connect.c: add a way for git-daemon to pass an error back to client

The current behavior of git-daemon is to simply close the connection on
any error condition. This leaves the client without any information as
to the cause of the failed fetch/push/etc.

This patch allows get_remote_heads to accept a line prefixed with "ERR"
that it can display to the user in an informative fashion. Once clients
can understand this ERR line, git-daemon can be made to properly report
"repository not found", "permission denied", or other errors.

Example

S: ERR No matching repository.
C: fatal: remote error: No matching repository.

fix overlapping memcpy in normalize_absolute_path

The comments for normalize_absolute_path explicitly claim
that the source and destination buffers may be the same
(though they may not otherwise overlap). Thus the call to
memcpy may involve copying overlapping data, and memmove
should be used instead.

pack-objects: avoid reading uninitalized dataJeff King Thu, 23 Oct 2008 04:31:03 +0000 (04:31 +0000)

pack-objects: avoid reading uninitalized data

In the main loop of find_deltas, we do:

struct object_entry *entry = *list++;
...
if (!*list_size)
...
break

Because we look at and increment *list _before_ the check of
list_size, in the very last iteration of the loop we will
look at uninitialized data, and increment the pointer beyond
one past the end of the allocated space. Since we don't
actually do anything with the data until after the check,
this is not a problem in practice.

But since it technically violates the C standard, and
because it provokes a spurious valgrind warning, let's just
move the initialization of entry to a safe place.

This fixes valgrind errors in t5300, t5301, t5302, t303, and
t9400.

correct cache_entry allocationJeff King Thu, 23 Oct 2008 04:30:58 +0000 (04:30 +0000)

correct cache_entry allocation

Most cache_entry structs are allocated by using the
cache_entry_size macro, which rounds the size of the struct
up to the nearest multiple of 8 bytes (presumably to avoid
memory fragmentation).

There is one exception: the special "conflict entry" is
allocated with an empty name, and so is explicitly given
just one extra byte to hold the NUL.

However, later code doesn't realize that this particular
struct has been allocated differently, and happily tries
reading and copying it based on the ce_size macro, which
assumes the 8-byte alignment.

This can lead to reading uninitalized data, though since
that data is simply padding, there shouldn't be any problem
as a result. Still, it makes sense to hold the padding
assumption so as not to surprise later maintainers.

This fixes valgrind errors in t1005, t3030, t4002, and
t4114.

git-gui: Do not munge conflict marker lines in a normal diff

Previously, conflict markers were highlighted in two ways: (1) They
received a distinguishing color; and (2) they had the '+' removed at the
beginning of the line. However, by doing (2), a hunk that contained
conflict markers could not be staged or unstaged because the resulting
patch was corrupted. With this change we no longer modify the diff text
of a 2-way diff, so that "Stage Hunk" and friends work.

Note that 3-way diff of a conflicted file is unaffected by this change,
and '++' before conflict markers is still removed. But this has no negative
impact because in this mode staging hunks or lines is disabled anyway.

git-gui: Add a simple implementation of SSH_ASKPASS.

OpenSSH allows specifying an external program to use
for direct user interaction. While most Linux systems
already have such programs, some environments, for
instance, msysgit, lack it. This patch adds a simple
fallback Tcl implementation of the tool.

In msysgit it is also necessary to set a fake value of
the DISPLAY variable, because otherwise ssh won't even
try to use SSH_ASKPASS handlers.

git-gui: Add a dialog that shows the OpenSSH public key.

Generating a new SSH key or finding an existing one may
be a difficult task for non-technical users, especially
on Windows.

This commit adds a new dialog that shows the public key,
or allows the user to generate a new one if none were found.
Since this is a convenience/informational feature for new
users, and the dialog is mostly read-only, it is located
in the Help menu.

The command line used to invoke ssh-keygen is designed to
force it to use SSH_ASKPASS if available, or accept empty
passphrases, but _never_ wait for user response on the tty.

compat/cygwin.c: make runtime detection of lstat/stat lessor impact

The original patch that lead to an earlier commit adbc0b6 (cygwin: Use
native Win32 API for stat, 2008-09-30) did not call git_default_config()
and it was a good thing. The lazy config reading when lstat/stat is
called for the first time to find out if core.filemode is set can happen
anytime in the calling program. If it happens after the calling program
parsed the configuration file to prime its default parameter settings and
processed its command line parameters to tweak them, this will overwrite
the values set by the program with the values read from the config file.

This essentially reverts the code to the version as submitted by Mark,
with a bit more comments to clarify why we do not fall back on the default
configuration parser from git_cygwin_config().

you get a call to add_refs_from_alternate() after somebody used the entry
(has_loose_object() has been called, for example), *ent->name would not be

gitweb: generate parent..current URLs

If use_pathinfo is enabled, href now creates links that contain paths in
the form $project/$action/oldhash:/oldname..newhash:/newname for actions
that use hash_parent etc.

If any of the filename contains two consecutive dots, it's kept as a CGI
parameter since the resulting path would otherwise be ambiguous.

gitweb: parse parent..current syntax from PATH_INFO

This patch makes it possible to use an URL such as
project/action/somebranch..otherbranch:/filename to get a diff between
different version of a file. Paths like
project/action/somebranch:/somefile..otherbranch:/otherfile are parsed
as well.

All '*diff' actions and in general actions that use $hash_parent[_base]
and $file_parent (e.g. 'shortlog') can now get all of their parameters
from PATH_INFO

This allows hooks like pre-receive to look at the client's IP

Of course the IP address can't be used to get strong security;
git-daemon isn't the right thing to use if you need that. However,
basic IP address checking can be good enough in some situations.

REMOTE_ADDR is the same environment variable used to communicate the

git-remote: list branches in vertical lists

Previously, branches were listed on a single line in each section. But
if there are many branches, then horizontal, line-wrapped lists are very
inconvenient to scan for a human. This makes the lists vertical, i.e one
branch per line is printed.

Since "git remote" is porcelain, we can easily make this

rm: loosen safety valve for empty filesJeff King Tue, 21 Oct 2008 13:54:19 +0000 (09:54 -0400)

rm: loosen safety valve for empty files

If a file is different between the working tree copy, the index, and the
HEAD, then we do not allow it to be deleted without --force.

However, this is overly tight in the face of "git add --intent-to-add":

$ git add --intent-to-add file
$ : oops, I don't actually want to stage that yet
$ git rm --cached file
error: 'empty' has staged content different from both the
file and the HEAD (use -f to force removal)
$ git rm -f --cached file

Unfortunately, there is currently no way to distinguish between an empty
file that has been added and an "intent to add" file. The ideal behavior
would be to disallow the former while allowing the latter.

This patch loosens the safety valve to allow the deletion only if we are
deleting the cached entry and the cached content is empty. This covers
the intent-to-add situation, and assumes there is little harm in not
protecting users who have legitimately added an empty file. In many
cases, the file will still be empty, in which case the safety valve does
not trigger anyway (since the content remains untouched in the working
tree). Otherwise, we do remove the fact that no content was staged, but
given that the content is by definition empty, it is not terribly
difficult for a user to recreate it.

However, we still document the desired behavior in the form of two
tests. One checks the correct removal of an intent-to-add file. The other
checks that we still disallow removal of empty files, but is marked as
expect_failure to indicate this compromise. If the intent-to-add feature
is ever extended to differentiate between normal empty files and
intent-to-add files, then the safety valve can be re-tightened.

builtin-blame: Reencode commit messages according to git-log rules.

Currently git-blame outputs text from the commit messages
(e.g. the author name and the summary string) as-is, without
even providing any information about the encoding used for
the data. It makes interpreting the data in multilingual
environment very difficult.

This commit changes the blame implementation to recode the
messages using the rules used by other commands like git-log.
Namely, the target encoding can be specified through the
i18n.commitEncoding or i18n.logOutputEncoding options, or
directly on the command line using the --encoding parameter.

Converting the encoding before output seems to be more
friendly to the porcelain tools than simply providing the
value of the encoding header, and does not require changing
the output format.

If anybody needs the old behavior, it is possible to
achieve it by specifying --encoding=none.

rebase-i-p: minimum fix to obvious issues

Jeff King noticed that this series uses non-portable ${var:0:7} syntax
to splice a string, which is not even in POSIX, in the script. A quick
look at around the offending part revealed a few issues, which this commit
fixes:

* Why filter output from "rev-list --left-right A...B" and look for the
ones that begin with ">"? Wouldn't "rev-list A..B" give that?

* The abbreviated SHA-1 are made with "rev-list --abbrev=7" into $TODO in
an earlier invocation, and it can be more than 7 letters to avoid
ambiguity. Not just that "${r:0:7} is not even in POSIX", but use of
it here is actively wrong.

* There is no point in catting a single file and piping it into grep.

gitk: Turn short SHA1 names into links too

This changes the link detection logic to accept strings of between 6
and 40 hex characters as a possible SHA1 ID of another commit, rather
than insisting on seeing the full 40 hex characters.

To make the logic that turns a possible link into an actual link work
with abbreviated IDs, this changes the way the commitinterest array is
used, and puts the code that deals with it in a pair of new functions.
The commitinterest array is now indexed by just the first 4 characters
of the interesting SHA1 ID, and each element is a list of id + command
pairs. This also pulls out the logic for expanding an abbreviated
SHA1 to the list of matching full IDs into its own function (the way
it is done is still the same slow way it was done before, which should
be improved some day).

This also fixes the bug where clicking on a link would take you to the
wrong commit if the line number of the target had changed since the
link was made.

This is based on a patch by Linus Torvalds, but totally rewritten by me.

fix multiple issues in index-packNicolas Pitre Mon, 20 Oct 2008 20:46:19 +0000 (16:46 -0400)

fix multiple issues in index-pack

Since commit 9441b61dc5, two issues affected correct behavior of
index-pack:

1) The real_type of a delta object is the 'real_type' of its base, not
the 'type' which can be a "delta type". Consequence of this is a
corrupted pack index file which only needs to be recreated with a
good index-pack command ('git verify-pack' will flag those).

2) The code sequence:

result->data = patch_delta(get_base_data(base), base->obj->size,
delta_data, delta_size, &result->size);

has two issues of its own since base->obj->size should instead be
base->size as we want the size of the actual object data and not
the size of the delta object it is represented by. Except that
simply replacing base->obj->size with base->size won't make the
code more correct as the C language doesn't enforce a particular
ordering for the evaluation of needed arguments for a function call,
hence base->size could be pushed on the stack before get_base_data()
which initializes base->size is called.

Fix testcase failure when extended attributes are in use

06cbe855 (Make core.sharedRepository more generic, 2008-04-16) made
several testcases in t1301-shared-repo.sh which fail if on a system
which creates files with extended attributes (e.g. SELinux), since ls
appends a '+' sign to the permission set in such cases. In fact,
POSIX.1 allows ls to add a single printable character after the usual
3x3 permission bits to show that an optional alternate/additional access
method is associated with the path.

This fixes the testcase to strip any such sign prior to verifying the
permission set.
