Luben Tuikov changed 'lineno' link from leading to commit which gave
current version of given block of lines, to leading to parent of this
commit in 244a70e (Blame "linenr" link jumps to previous state at
"orig_lineno"). This made possible data mining using 'blame' view.
The current implementation calls rev-parse once per each blamed line
to find parent revision of blamed commit, even when the same commit
appears more than once, which is inefficient.
This patch mitigates this issue by caching $parent_commit info in
%metainfo, which makes gitweb call rev-parse only once per each
unique commit in the output from "git blame".
In the tables below you can see simple benchmark comparing gitweb
performance before and after this patch

As you can see the greater ratio of lines in file to unique commits
in blame output, the greater gain from the new implementation.
Legend:
[1] Number of lines:
$ wc -l <file>
[2] Number of unique commits in the blame output:
$ git blame -p <file> | grep author-time | wc -l
[3] Time for running "git blame -p" (user time, single run):
$ time git blame -p <file> >/dev/null
[4] Time to run gitweb as Perl script from command line:
$ gitweb-run.sh "p=.git;a=blame;f=<file>" > /dev/null 2>&1
The gitweb-run.sh script includes slightly modified (with adjusted
pathnames) code from gitweb_run() function from the test script
t/t9500-gitweb-standalone-no-errors.sh; gitweb config file
gitweb_config.perl contents (again up to adjusting pathnames; in
particular $projectroot variable should point to top directory of git
repository) can be found in the same place.
Discussion
~~~~~~~~~~
A possible future improvement would be to open a bidi pipe to
"git cat-file --batch-check", (like in Git::Repo in gitweb caching by
Lea Wiemann), feed $long_rev^ to it, and parse its output, which is
in the following form:
926b07e694599d86cec668475071b32147c95034 commit 637
This would mean one call to git-cat-file for the whole 'blame' view,
instead of one call to git-rev-parse per each unique commit in blame
output.
Yet another solution would be to change use of validate_refname() to
validate_revision() when checking script parameters (CGI query or
path_info), with validate_revision being something like the following:
sub validate_revision {
my $rev = shift;
return validate_refname(strip_rev_suffixes($rev));
}
so we don't need to calculate $long_rev^, but can pass "$long_rev^" as
'hb' parameter.
This solution has the advantage that it can be easily adapted to future
incremental blame output.

If you have unstaged changes in your working tree and try to
rebase, you will get the cryptic "foo: needs update"
message, but nothing else. If you have staged changes, you
get "your index is not up-to-date".
Let's improve this situation in two ways:
- for unstaged changes, let's also tell them we are
canceling the rebase, and why (in addition to the "needs
update" lines)
- for the staged changes case, let's use language that is a
little more clear to the user: their index contains
uncommitted changes

Among others, here are the highlights:
* move variable declaration closer to the place it is set and used,
if possible,
* uniquify and simplify coding style a bit, which includes removing
unnecessary '()'.
* check type only if $hash was defined, as otherwise from the way
git_get_hash_by_path() is called (and works), we know that it is
a blob,
* use modern calling convention for git-blame,
* remove unused variable,
* don't use implicit variables ($_),
* add some comments

Currently we just skip rewrite diffs for binary files; this
patch makes an exception for files which will be textconv'd,
and actually performs the textconv before generating the
diff.
Conceptually, rewrite diffs should be in the exact same
format as the a non-rewrite diff, except that we refuse to
share any context. Thus it makes very little sense for "git
diff" to show a textconv'd diff, but for "git diff -B" to
show "Binary files differ".

The current emit_rewrite_diff code always writes a text patch without
checking whether the content is binary. This means that if you end up with
a rewrite diff for a binary file, you get lots of raw binary goo in your
patch.
Instead, if we have binary files, then let's just skip emit_rewrite_diff
altogether. We will already have shown the "dissimilarity index" line, so
it is really about the diff contents. If binary diffs are turned off, the
"Binary files a/file and b/file differ" message should be the same in
either case. If we do have binary patches turned on, there isn't much
point in making a less-efficient binary patch that does a total rewrite;
no human is going to read it, and since binary patches don't apply with
any fuzz anyway, the result of application should be the same.

find_parent_branch generates branch@rev type branches when one has to
look back through SVN history to properly get the history for a branch
copied from somewhere not already being tracked by git-svn. If in the
process of fetching this history, git-svn is interrupted, then when one
fetches again, it will use whatever was last fetched as the parent
commit and fail to fetch any more history which it didn't get to before
being terminated. This is especially troubling in that different
git-svn copies of the same SVN repository can end up with different
commit sha1s, incorrectly showing the history as divergent and
precluding easy collaboration using git push and fetch.
To fix this, when we initialise the Git::SVN object $gs to search for
and perhaps fetch history, we check if there are any commits in SVN in
the range between the current revision $gs is at, and the top revision
for which we were asked to fill history. If there are commits we're
missing in that range, we continue the fetch from the current revision
to the top, properly getting all history before using it as the parent
for the branch we're trying to create.

Commits without an encoding header are supposed to
be encoded in utf8. While this apparently hasn't always
been the case, currently it is the active convention, so
it is better to follow it; otherwise people who have to
use commitEncoding on their machines are unable to read
utf-8 commits made by others.
I also think that it is preferrable to display the warning
about an unsupported value of commitEncoding more prominently,
because this condition may lead to surprising behavior and,
eventually, to loss of data.

Currently using '..' or '.' in the file path for gui blame
causes it to break, because the path is passed inside the
SHA:PATH spec to cat-file, which apparently does not understand
such items. As a result, cat-file returns nothing, and the
viewer crashes because of an "index out of range" error.
This commit adds a simple function that normalizes such paths.
I choose not to use [file normalize], because it uses some data
from the file system, e.g. dereferences symlinks, and creates
an absolute path, while blame may be used to inspect historical
information that bears no relation to the current filesystem state.

Some history viewers use the diff plumbing to generate diffs
rather than going through the "git diff" porcelain.
Currently, there is no way for them to specify that they
would like to see the text-converted version of the diff.
This patch adds a "--textconv" option to allow such a
plumbing user to allow text conversion. The user can then
tell the viewer whether or not they would like text
conversion enabled.
While it may be tempting add a configuration option rather
than requiring each plumbing user to be configured to pass
--textconv, that is somewhat dangerous. Text-converted diffs
generally cannot be applied directly, so each plumbing user
should "opt in" to generating such a diff, either by
explicit request of the user or by confirming that their
output will not be fed to patch.

Right now for the diff porcelain and the log family, we
call:
init_revisions();
setup_revisions();
DIFF_OPT_SET(ALLOW_TEXTCONV);
However, that means textconv will _always_ be on, instead of
being a default that can be manipulated with
setup_revisions. Instead, we want:
init_revisions();
DIFF_OPT_SET(ALLOW_TEXTCONV);
setup_revisions();
which is what this patch does.
We'll go ahead and move the callsite in wt-status, also;
even though the user can't pass any options here, it is a
cleanup that will help avoid any surprise later if the
setup_revisions line is changed.

The user may put some effort into writing an annotated tag
message. When the tagging process later fails (which can
happen fairly easily, since it may be dependent on gpg being
correctly configured and used), there is no record left on
disk of the tag message.
Instead, let's keep the TAG_EDITMSG file around until we are
sure the tag has been created successfully. If we die
because of an error, the user can recover their text from
that file. Leaving the file in place causes no conflicts;
it will be silently overwritten by the next annotated tag
creation.
This matches the behavior of COMMIT_EDITMSG, which stays
around in case of error.

The "show origin of this line" function wasn't working when gitk was
run in a subdirectory, since it passed the path relative to the
top-level directory to git blame. This fixes it by passing the
absolute path to the file instead of the relative path.
The same problem occurs when running git gui blame, except that
git gui blame appears not to be able to accept an absolute path to the
file, so we make a relative path using a new [make_relative] function.
Finally, this fixes a bug in [show_line_source] where we weren't
setting id, resulting in an error when trying to find the origin of
a line in the fake commit for local changes not checked in, when its
parent was a real commit (i.e. there were no changes checked in).
