git-gui: Gracefully handle bad TCL_PATH at compile time
Petr Baudis pointed out the main git.git repository's Makefile dies
now if git-gui 0.7.0-rc1 or later is being used and TCL_PATH was not
set to a working tclsh program path. This breaks people who may have
a working build configuration today and suddenly upgrade to the latest
git release.
The tclIndex is required for git-gui to load its associated lib files,
but using the Tcl auto_load procedure to source only the files we need
is a performance optimization. We can emulate the auto_load by just
source'ing every file in that directory, assuming we source class.tcl
first to initialize our crude class system.

gitweb: Empty patch for merge means trivial merge, not no differences
Earlier commit 4280cde95fa4e3fb012eb6d0c239a7777baaf60c made gitweb
show "No differences found" message for empty diff, for the HTML
output. But for merge commits, either -c format we use or --cc format,
empty diff doesn't mean no differences, but trivial merge.
Show "Trivial merge" message instead of "No differences found" for
merges.

David Kågedal proposed that gitweb should explicitely request
being somewhat smaller than normal, because it has good use for
long lines. However gitweb presents a table with several
columns, so having wider line is OK for it. Therefore explicit
'font-size: small' would make sense. Apparently many people on
the list seem to agree with him.
import-tars: Use the "Link indicator" to identify directories
Earlier, we used the mode to determine if a name was associated with
a directory. This fails, since some tar programs do not set the mode
correctly. However, the link indicator _has_ to be set correctly.

converting their existing repositories won't have to make any changes to

Given that it's a feature that's meant to calm those very people, it
seems obtuse to make them edit every file just to make use of it.
I think that bzr uses $Id$; Mercurial has examples hooks for $Id$;

git-svn: don't attempt to minimize URLs by default
For tracking branches and tags, git-svn prefers to connect
to the root of the repository or at least the level that
houses branches and tags as well as trunk. However, users
that are accustomed to tracking a single directory have
no use for this feature.
As pointed out by Junio, users may not have permissions to
connect to connect to a higher-level path in the repository.
While the current minimize_url() function detects lack of
permissions to certain paths _after_ successful logins, it
cannot effectively determine if it is trying to access a
login-only portion of a repo when the user expects to
connect to a part where anonymous access is allowed.
For people used to the git-svnimport switches of
--trunk, --tags, --branches, they'll already pass the
repository root (or root+subdirectory), so minimize URL
isn't of too much use to them, either.
For people *not* used to git-svnimport, git-svn also
supports:
git-svn: fix segfaults due to initial SVN pool being cleared
Some parts of SVN always seem to use it, even if the SVN::Ra
object we're using is no longer used and we've created a new one
in its place. It's also true that only one SVN::Ra connection
can exist at once... Using SVN::Pool->new_default when the
SVN::Ra object is created doesn't seem to help very much,
either...
Hopefully this fixes all segfault problems users have been
experiencing over the past few months.
This patch was originally intended to make the Perl GC more
sensitive to the SVN::Pool objects and not accidentally clean
them up when they shouldn't be (causing segfaults). That didn't
work, but this patch makes the code a bit cleaner regardless
Put our caches for get_dir and check_path calls directly into
the SVN::Ra object so they auto-expire when it is destroyed.
dirents returned by get_dir() no longer needs the pool object
stored persistently along with the cache data, as they'll be
converted to native Perl hash references.
Since calling rev_proplist repeatedly per-revision is no longer
needed in git-svn, we do not cache calls to it.
git-svn: don't drop the username from URLs when dcommit is run
We no longer store usernames in URLs stored in git-svn-id lines
for dcommit, so we shouldn't rely on those URLs when connecting
to the remote repository to commit.
git-config: do not forget seeing "a.b.var" means we are out of "a.var" section.
Earlier code tried to be half-careful and knew the logic that
seeing "a.var" after seeing "a.b.var" is a sign of the previous
"a.b." section has ended, but forgot it has to handle the other
way. Seeing "a.b.var" after seeing "a.var" is a sign that "a."
section has ended, so a new "a.var2" variable should be added
before the location "a.b.var" appears.

the p4import references are useless anywhere but in the directory managed

read-tree -m -u: avoid getting confused by intermediate symlinks.
When switching from a branch with both x86_64/boot/Makefile and
i386/boot/Makefile to another branch that has x86_64/boot as a
symlink pointing at ../i386/boot, the code incorrectly removed
i386/boot/Makefile.
This was because we first removed everything under x86_64/boot
to make room to create a symbolic link x86_64/boot, then removed
x86_64/boot/Makefile which no longer exists but now is pointing
at i386/boot/Makefile, thanks to the symlink we just created.
This fixes it by using the has_symlink_leading_path() function
introduced previously for git-apply in the checkout codepath.
Earlier, "git checkout" was broken in t4122 test due to this
bug, and the test had an extra "git reset --hard" as a
workaround, which is removed because it is not needed anymore.
apply: do not get confused by symlinks in the middle
HPA noticed that git-rebase fails when changes involve symlinks
in the middle of the hierarchy. Consider:
* The tree state before the patch is applied has arch/x86_64/boot
as a symlink pointing at ../i386/boot/
* The patch tries to remove arch/x86_64/boot symlink, and
create bunch of files there: .gitignore, Makefile, etc.
git-apply tries to be careful while applying patches; it never
touches the working tree until it is convinced that the patch
would apply cleanly. One of the check it does is that when it
knows a path is going to be created by the patch, it runs
lstat() on the path to make sure it does not exist.
This leads to a false alarm. Because we do not touch the
working tree before all the check passes, when we try to make
sure that arch/x86_64/boot/.gitignore does not exist yet, we
haven't removed the arch/x86_64/boot symlink. The lstat() check
ends up seeing arch/i386/boot/.gitignore through the
yet-to-be-removed symlink, and says "Hey, you already have a
file there, but what you fed me is a patch to create a new
file. I am not going to clobber what you have in the working
tree."
We have similar checks to see a file we are going to modify does
exist and match the preimage of the diff, which is done by
directly opening and reading the file.
For a file we are going to delete, we make sure that it does
exist and matches what is going to be removed (a removal patch
records the full preimage, so we check what you have in your
working tree matches it in full -- otherwise we would risk
losing your local changes), which again is done by directly
opening and reading the file.
These checks need to be adjusted so that they are not fooled by
symlinks in the middle.
- To make sure something does not exist, first lstat(). If it
does not exist, it does not, so be happy. If it _does_, we
might be getting fooled by a symlink in the middle, so break
leading paths and see if there are symlinks involved. When
we are checking for a path a/b/c/d, if any of a, a/b, a/b/c
is a symlink, then a/b/c/d does _NOT_ exist, for the purpose
of our test.
This would fix this particular case you saw, and would not
add extra overhead in the usual case.
- To make sure something already exists, first lstat(). If it
does not exist, barf (up to this, we already do). Even if it
does seem to exist, we might be getting fooled by a symlink
in the middle, so make sure leading paths are not symlinks.
This would make the normal codepath much more expensive for
deep trees, which is a bit worrisome.
This patch implements the first side of the check "making sure
it does not exist". The latter "making sure it exists" check is
not done yet, so applying the patch in reverse would still
fail, but we have to start from somewhere.
When we are applying a patch that creates a blob at a path, or
when we are switching from a branch that does not have a blob at
the path to another branch that has one, we need to make sure
that there is nothing at the path in the working tree, as such a
file is a local modification made by the user that would be lost
by the operation.
Normally, lstat() on the path and making sure ENOENT is returned
is good enough for that purpose. However there is a twist. We
may be creating a regular file arch/x86_64/boot/Makefile, while
removing an existing symbolic link at arch/x86_64/boot that
points at existing ../i386/boot directory that has Makefile in
it. We always first check without touching filesystem and then
perform the actual operation, so when we verify the new file,
arch/x86_64/boot/Makefile, does not exist, we haven't removed
the symbolic link arc/x86_64/boot symbolic link yet. lstat() on
the file sees through the symbolic link and reports the file is
there, which is not what we want.
The function has_symlink_leading_path() function takes a path,
and sees if any of the leading directory component is a symbolic
link.
When files in a new directory are created, we tend to process
them together because both index and tree are sorted. The
function takes advantage of this and allows the caller to cache
and reuse which symbolic link on the filesystem caused the
function to return true.
The calling sequence would be:
char last_symlink[PATH_MAX];
*last_symlink = '\0';
for each index entry {
if (!lose)
continue;
if (lstat(it))
if (errno == ENOENT)
; /* happy */
else
error;
else if (has_symlink_leading_path(it, last_symlink))
; /* happy */
else
error; /* would lose local changes */
unlink_entry(it, last_symlink);

git-clone: don't get fooled by $PWD
Fix documentation of tag in git-fast-import.txt
If you have /home/me/git symlink pointing at /pub/git/mine,
trying to clone from /pub/git/his/ using relative path would not
work as expected:
$ cd /home/me
$ cd git
$ ls ../
his mine
$ git clone -l -s -n ../his/stuff.git
This is because "cd ../his/stuff.git" done inside git-clone to
check if the repository is local is confused by $PWD, which is
set to /home/me, and tries to go to /home/his/stuff.git which is
different from /pub/git/his/stuff.git.
We could probably say "set -P" (or "cd -P") instead, if we know
the shell is POSIX, but the way the patch is coded is probably
more portable.

gitweb: choose appropriate view for file type if a= parameter missing
gitweb URLs use the a= parameter for the view to use on the given path, such
as "blob" or "tree". Currently, if a gitweb URL omits the a= parameter,
gitweb just shows the top-level repository summary, regardless of the path
given. gitweb could instead choose an appropriate view based on the file
type: blob for blobs (files), tree for trees (directories), and summary if
no path given (the URL included no f= parameter, or an empty f= parameter).
Apart from making gitweb more robust and supporting URL editing more easily,
this change would aid the creation of shortcuts to git repositories using
simple substitution, such as:
http://example.org/git/?p=path/to/repo.git;hb=HEAD;f=%s
With this patch, if given the hash through the h= parameter, or the hash
base (hb=) and a filename (f=), gitweb uses cat-file -t to automatically set
the a= parameter.

Rather than storing the temporary commit message data in .msg (in
the working tree) we now store the message data in .git/MERGE_MSG.
By storing the message in the .git/ directory we are sure we will
never have a collision with a user file, should a project actually
have a ".msg" file in their top level tree. We also don't need to
worry about leaving this stale file behind during a `reset --hard`
and have it show up in the output of status.
We are using .git/MERGE_MSG here to store the temporary message as
it is an already established convention between git-merge, git-am
and git-rebase that git-commit will default the user's edit buffer
to the contents of .git/MERGE_MSG. If the user is going to need
to resolve this commit or wants to edit the message on their own
prepping that file with the desired message "just works".

We can use [list ...] rather than "", especially when we are talking
about values as then they are properly escaped if necessary. Small
nit, but probably not a huge deal as the only data being inlined here
is Tk paths.
Some of the lines in the parser code were longer than 80 characters
wide, and they actually were all the same value on the end part of
the line. Rather than keeping the mess copied-and-pasted around we
can set the last argument into a local variable and reuse it many
times.
The commit display code was also rather difficult to read on an 80
character wide terminal, so I'm moving it all into a double quoted

are optional. We assume the argument is a filename if the file
exists in the working directory, otherwise we assume the argument
is a revision name. A -- can be supplied between the two to force
parsing, or before the filename to force it to be a filename.

git-gui within that subdirectory. This is happening because we did
not take the user's prefix into account when we computed the file
path in the repository.
We now assume the prefix as returned by rev-parse --show-prefix is
valid and we use that during the command line blame subcommand when
we apply the parameters.

git-gui: Convert blame to the "class" way of doing things
Our blame viewer code has historically been a mess simply
because the data for multiple viewers was all crammed into
a single pair of Tcl arrays. This made the code hard to
read and even harder to maintain.
Now that we have a slightly better way of tracking the data
for our "meta-widgets" we can make use of it here in the
blame viewer to cleanup the code and make it easier to work
with long term.

git-gui: Don't attempt to inline array reads in methods
If a variable reference to a field is to an array, and it is
the only reference to that field in that method we cannot make
it an inlined [set foo] call as the regexp was converting the
Tcl code wrong. We were producing "[set foo](x)" for "$foo(x)",
and that isn't valid Tcl when foo is an array. So we just punt
if the only occurance has a ( after it.

git-gui: Convert browser, console to "class" format
Now that we have a slightly easier method of working with per-widget
data we should make use of that technique in our browser and console
meta-widgets, as both have a decent amount of information that they
store on a per-widget basis and our current approach of handling
it is difficult to follow.

As most of the git-gui interface is based upon "meta-widgets"
that need to carry around a good deal of state (e.g. console
windows, browser windows, blame viewer) we have a good deal
of messy code that tries to store this meta-widget state in
global arrays, where keys into the array are formed from a
union of a unique "object instance id" and the field name.
This is a simple class system for Tcl that allows us to
hide much of that mess by making Tcl do what it does best;
process strings to manipulate its own code during startup.
Each object instance is placed into its own namespace. The
namespace is created when the object instance is created and
the namespace is destroyed when the object instance is removed
from the system. Within that namespace we place variables for
each field within the class; these variables can themselves be
scalar values or full-blown Tcl arrays.
All fields must be declared before any constructors or methods. This
allows our class to generate a list of the fields so it can properly
alter the definition of the constructor and method bodies prior to
passing them off to Tcl for definition with proc. A field may optionally
be given a default/initial value. This can only be done for non-array
type fields.
Constructors are given full access to all fields of the class, so they
can initialize the data values. The default values of fields (if any)
are set before the constructor runs, and the implicit local variable
$this is initialized to the instance identifier.
Methods are given access to fields they actually use in their body.
Every method has an implicit "this" argument inserted as its first
parameter; callers of methods must be sure they supply this value.
Some basic optimization tricks are performed (but not much). We
try to only upvar (locally bind) fields that are accessed within a
method, but we err on the side of caution and may upvar more than
we need to. If a variable is accessed only once within a method
and that access is by $foo (read) we avoid the upvar and instead
use [set foo] to obtain the value. This is slightly faster as Tcl
does not need to lookup the variable twice.
We also offer some small syntatic sugar for interacting with Tk and
the fileevent callback system in Tcl. If a field (say "foo") is used
as "@foo" we insert instead the true global variable name of that
variable into the body of the constructor or method. This allows easy
binding to Tk textvariable options, e.g.:
label $w.title -textvariable @title
Proper namespace callbacks can also be setup with the special cb proc
that is defined in each namespace. [cb _foo a] will invoke the method
_foo in the current namespace, passing it $this as the first (implied)
parameter and a as the second parameter. This makes it very simple to
connect an object instance to a -command option for a Tk widget or to
a fileevent readable or writable for a file channel.

git-gui: Allow shift-{k,j} to select a range of branches to merge
I found it useful to be able to use j/k (vi-like keys) to move
up and down the list of branches to merge and shift-j/k to do
the selection, much as shift-up/down (arrow keys) would alter
the selection.

Build fails for git 1.5.1.3 on AIX, with the message:
utf8.c:66: error: conflicting types for 'wcwidth'
/.../lib/gcc/powerpc-ibm-aix5.3.0.0/4.0.3/include/string.h:266: error: previous declaration of 'wcwidth' was here
Fix this by renaming our static variant to our own name.
