git-svn: detect and fail gracefully when dcommitting to a void
The command
git svn clone (URL of an empty SVN repo here)
works, creates an empty git repository. I can perform the initial
commit there, but then, "git svn dcommit" says :
Use of uninitialized value in concatenation (.) or string at .../git-svn line 414.
Committing to ...
Unable to determine upstream SVN information from HEAD history
I guess a correct management of the initial commit in git-svn would be
hard to implement, but at least, the error message can be improved.
First step is something like the patch below, and better would be for
"git svn clone" to warn that it won't be able to do much with the
cloned repo.

cvsimport: always pass user data to "system" as a list
fix reflog approxidate parsing bug
Fix use after free() in builtin-fetch
fetch-pack: do not stop traversing an already parsed commit
Use "=" instead of "==" in condition as it is more portable
into its constituent ref, reflog date, and path components.
We never actually munge the string itself, but instead keep
offsets into the string with their associated lengths.
When we call approxidate on the contents inside braces,
however, we pass just a string without a length. This means
that approxidate could sometimes look past the closing brace
and (erroneously) interpret the rest of the string as part
of the date.

The purpose of --first-parent is to view the tree without looking at
side branche. This is accomplished by pretending there are no other
parents than the first parent when encountering a merge.
The current code marks the other parents as seen, which means that the tree
traversal will behave differently depending on the order merges are handled.
When a fast forward is artificially recorded as a merge,
-----
/ \
D---E---F---G master
the current first-parent code considers E to be seen and stops the
traversal after showing G and F.

gitk: Fix handling of tree file list with special chars in names
Alex Riesen pointed out that displaying a commit in 'tree' mode fails
if some files have names with special characters such as '{' or '}' in
them, due to the fact that we treat the line returned from git ls-tree
as a Tcl list at one point.
This fixes it by doing what I originally intended but didn't quite
get right. We split the line from git ls-tree at the first tab and
treat the part before the tab as a list (which is OK since it doesn't
have special characters in it) and the part after the tab as the
filename.
Michael G. Noll said in comments to the "Switching my code repository from
Subversion (SVN) to git" article (http://tinyurl.com/37v67l) in his "My
digital moleskine" blog, that one of the things he is missing in gitweb
from SVN::Web is an RSS feed with news/information of the current view
(including RSS feed for single file or directory).
This is not exactly true, as since refactoring feed generation in af6feeb
(gitweb: Refactor feed generation, make output prettier, add Atom feed,
2006-11-19), gitweb can generate feeds (RSS or Atom) for history of a
given branch, history limited to a given directory, or history of a given
file. Nevertheless this required handcrafting the URL to get wanted RSS
feed.
This commit makes gitweb select feed links in the HTML header and in
page footer depending on current view (action). It is more elaborate,
and I guess more correct, than simple patch adding $hash ('h')
parameter to *all* URLs, including feed links, by Jean-Baptiste Quenot
Subject: [PATCH] gitweb: Add hash parameter in feed URL when a hash
is specified in the current request
Message-ID: <ae63f8b50803211138y6355fd11pa64cda50a1f53011@mail.gmail.com>
If $hash ('h') or $hash_base ('hb') parameter is a branch name
(i.e. it starts with 'refs/heads/'; all generated URLs use this form
to discriminate between tags and heads), it is used in feed URLs; if
$file_name ('f') is defined, it is used in feed URLs. Feed title is
set according to the kind of web feed: it is either 'log' for generic
feed, 'log of <branch>', 'history of <filename>' for generic history
(using implicit or explicit HEAD, i.e. current branch) or 'history of
<filename> on <branch>'.
There are special cases: 'heads' and 'forks' views should use OPML
providing list of available feeds; 'tags' probably also should use
OPML; there is no web feed equivalent to 'search' view. Currently all
those cases fallback to (show) default feed. Such feed link uses
"generic" class, and is shown in slightly lighter color for
distinction.
Currently feed can have but one starting point, and does not support
negative (exclude) commit arguments. Therefore for now for *diff
views it is chosen that feed follow the "to" part: to-name, to-commit
for 'blobdiff', 'treediff' and 'commitdiff' views.
Generating parameters for href() for feed link was separated
(refactored) into get_feed_info() subroutine.

"git add *" is actually fundamentally different from "git add .", and
yeah, you should generally use the latter.
The reason? The argument list is actually something different from what
you think it is. For git, it's a "pathspec", so what actualy happens is
that in *both* cases, it will really traverse the whole tree, and then
match every file it finds against the pathspec.
So think of the arguments not as a file list, but as a random bunch of
patterns to match against the files you have!
Which is why the cost is actually approximately O(n*m), where "n" is the
size of the working tree, and "m" is the number of pathspecs.
So the reason "git add ." is fast is actually that "m" in that case is
just 1 (just one trivial pattern), and then "git add *" is slow because
"m" is large (lots of complicated patterns). In both cases, 'n' is the
same (== the whole set of files in your working tree).
Anyway, here's a trivial patch that doesn't change this fundamental fact,
but that avoids doing anything *expensive* until we've done some cheap
initial tests. It may or may not help your test-case, but it's pretty
simple and it matches the other git optimizations in this area (ie
"conceptually handle the general case, but optimize the simple cases where
we can exit early")
Notice how this patch doesn' actually change the fundamental O(n^2)
behaviour, but it makes it much cheaper by generally avoiding the
expensive 'fnmatch' and 'strlen/strncmp' when they are obviously not
needed.

This simplifies a few things, makes a few things slightly more

represent a symref, http_fetch_ref() can return one.
Incidentally makes the string that http_fetch_ref() gets include "refs/"
(if appropriate), because that's how the name field of struct ref works.
As far as I can tell, the usage in walker:interpret_target() wouldn't have
worked previously, if it ever would have been used, which it wouldn't
(since the fetch process uses the hash instead of the name of the ref
there).

help: use "man.<tool>.cmd" as custom man viewer command
Currently "git help -m GITCMD" is restricted to a set of man viewers
defined at compile time. You can subvert the "man.<tool>.path" to
force "git help -m" to use a different man, viewer, but if you have a
man viewer whose invocation syntax does not match one of the current
tools then you would have to write a wrapper script for it.
This patch adds a git config variable "man.<tool>.cmd" which allows a
more flexible man viewer choice.
If you run "git help -m GITCMD" with the "man.viewer" config variable
set to an unrecognized tool then it will query the "man.<tool>.cmd"
config variable. If this variable exists, then the specified tool will
be treated as a custom man viewer and it will be run in a shell with
the man page name of the GITCMD added as extra parameter.

gitk: Reorganize processing of arguments for git log
This moves the scanning of the argument list for each view into a
new function, parseviewargs, which is called from start_rev_list.
This also makes the date mode and the merge mode be per-view rather
than global. In merge mode, we work out the list of relevant files
in a new function called from start_rev_list, so it will be updated
on File->Reload. Plus we now do that after running the argscmd, so
if we have one and it generates a -d or --merge option they will be
correctly handled now.
The other thing this does is to make errors detected in start_rev_list
not be fatal. Now instead of doing exit 1 we just pop up and error
window and put "No commits selected" in the graph pane.

1. check for an unambiguous 'dst' on the remote; if it

2. otherwise, check if 'dst' begins with 'refs/'; if it
does, create a new ref
3. otherwise, complain because we don't know where in the
refs hierarchy to put 'dst'
However, in some cases, we can guess about the ref type of
'dst' based on the ref type of 'src'. Specifically, before
complaining we now check:
2.5. if 'src' resolves to a ref starting with refs/heads
or refs/tags, then prepend that to 'dst'
So now this creates a new branch on the remote, whereas it
previously failed with an error message:
git push master:newbranch
Note that, by design, we limit this DWIM behavior only to
source refs which resolve exactly (including symrefs which
resolve to existing refs). We still complain on a partial
destination refspec if the source is a raw sha1, or a ref
expression such as 'master~10'.

gitweb: Fix 'history' view for deleted files with history
When asked for history of a file which is not present in given branch
("HEAD", i.e. current branch, or given by transient $hash_hase ('hb')
parameter), but is present deeper in the history (meaning that "git
rev-list --full-history $hash_base -- $file_name" is not empty), and
there is no $hash ('h') parameter set for a file, gitweb would spew
multiple of "Use of uninitialized value" warnings, and some links
would be missing. This commit fixes this bug.
This bug occurs in the rare cases when "git log -- <path>" is empty
and "git log --full-history -- <path>" is not, or to be more exact in
the cases when full-history starts later than given branch. It can
happen if you are using handcrafted gitwb URL, or if you follow
generic 'history' link or bookmark for a file which got deleted.
Gitweb tried to get file type ('tree', or 'blob', or even 'commit')
from the commit we start searching from (where the file was not
present), and not among found commits. This was the cause of "Use of
uninitialized value" warnings.
This commit also add tests for such situation to t9500 test.
While we are it, return HTTP error if there is _no_ history; it means
that file or directory was not found (for given branch). Also error

value (0077) can use this option to force file modes. For example,
'0640' is a group-readable but not group-writable regardless of
user's umask value. Values compatible with old Git versions are written

Traditionally git-rebase was implemented in terms of "format-patch" piped
to "am -3", to strike balance between speed (because it avoids a rather
expensive read-tree/merge-recursive machinery most of the time) and
flexibility (the magic "-3" allows it to fall back to 3-way merge as
necessary). However, this combination has one flaw when dealing with a
nonstandard commit log message format that has more than one lines in the
first paragraph.
This teaches "git am --rebasing" to take advantage of the fact that the
mbox message "git rebase" prepares for it records the original commit
object name, to get the log message from the original commit object
instead.
