When clicking on "log" from a tag we end up showing the log of whatever
branch we used to reach the tag. If the tag doesn't point onto a branch
then the tagged commit won't appear in this output.
By linking to tags with the head parameter instead of the "id" parameter
the log link will show the log of the tag. This is clearly desirable
when the tag has been reached from the refs UI and changing the
behaviour for tag decorations makes them match branch decorations where
log -> decoration -> log shows the log of the decoration.

Currently, when a user directly accesses the info command of a
repository, we exit cgit without printing anything to stdout, bringing
up error messages like "502 Bad Gateway" or "An error occurred while
reading CGI reply (no response received)". Instead of bailing out, at
least print the HTTP headers, including a reasonable error message.

Seeing the diff stat for a single file is pretty useless, so reset the
diff type before generating the links to individual files in the diff
stat so that the links will show a useful diff.

Using (DIFF_FORMAT_DIFFSTAT | DIFF_FORMAT_PATCH) causes Git to emit a
"---" line between the commit message and the body of the patch, which
fixes a regression introduced in commit 455b598 (ui-patch.c: Use
log_tree_commit() to generate diffs, 2013-08-20), prior to which we
inserted the "---" line ourselves.
DIFF_FORMAT_SUMMARY is added so that we match the output of
git-format-patch(1) without the "-p" option.

Use Git's built-in ident line splitting algorithm instead of
reimplementing it. This does not only simplify the code but also makes
sure that cgit is consistent with Git when it comes to author parsing.

Serving cgit via https and getting avatar via http gives error messages
about untrusted content. This decides whether or not to use https link
by looking at the environment variable HTTPS, which is set in CGI.
This prints the diffstat but stops before printing (or generating) any
of the body of the diff.
No cgitrc option is added here so that we can wait to see how useful
this is before letting people set it as the default.

This will allow us to introduce a new "stat only" diff mode without
needing an explosion of mutually incompatible flags.
The old "ss" query parameter is still accepted in order to avoid
breaking saved links, but we no longer generate any URIs using it;
instead the new "dt" (diff type) parameter is used.

Specifying a nonexistent README file via the readme option is sometimes
useful, e.g. when using scan-path and setting a global default.
Currently, we check whether there is only one option in the readme
option and, if so, we choose that file without checking whether it
exists. As a consequence, all repositories are equipped with an about
link in the aforementioned scenario, even if there is no about file.
Remove the early check for the number of keys and always check whether
the file exists instead.

This is slightly more involved than just bumping the version number
because it pulls in a change to convert the commit buffer to a slab,
removing the "buffer" field from "struct commit". All sites that access
"commit->buffer" have been changed to use the new functions provided for
this purpose.

It looks like cached patches are truncated to the nearest 1024-byte
boundary in the patch body. E.g.:
> mricon@nikko:[/tmp]$ wget -O no-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=6e1b4fdad5157bb9e88777d525704aba24389bee"
...

Patch is complete, without truncation. Next hit, with cache in place:
> mricon@nikko:[/tmp]$ wget -O yes-cache
> "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/patch/?id=6e1b4

Length truncated to 4096. The cache on disk looks truncated as well, so
the bug must me during the process of saving cache. The same is true for
larger patches:

Since the "html" functions use raw write(2) to STDIO_FILENO, we don't
notice problems with most pages, but raw patches write using printf(3).
This is fine if we're outputting straight to stdout since the buffers
are flushed on exit, but we close the cache output before this, so the
cached output ends up being truncated.
Make sure the buffers are flushed when we finish outputting a patch so
that we avoid this.
No other UIs use printf(3) so we do not need to worry about them.
Actually, it's slightly more interesting than this... since we don't set
GIT_FLUSH, Git decides whether or not it will flush stdout after writing
each commit based on whether or not stdout points to a regular file (in
maybe_flush_or_die()).
Which means that when writing directly to the webserver, Git flushes
stdout for us, but when we redirect stdout to the cache it points to a
regular file so Git no longer flushes the output for us.
The patch is still correct, but perhaps the full explanation is
interesting!

If you search for a bogus range string here:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/
Using something like "range" and "qwerty123456", it returns an "Internal
Server Error" and the following in the logs:

The cache will kick in, so if you search for the same string again,
it'll show an empty range, so you have to change the bogus strings each
time.
This is because we just pass the arguments straight to Git's revision
parsing machinery which die()s if it cannot parse an argument, printing
the above to stderr and exiting.
The patch below makes it a bit friendlier by just ignoring unhandled
arguments, but I can't see an easy way to report errors when we can't
parse revision arguments without losing the flexibility of supporting
all of the revision specifiers supported by Git.

prefixcmp() and suffixcmp() have been remove, functionality is now
provided by starts_with() and ends_with(). Retrurn values have been
changed, so instead of just renaming we have to fix logic.
Everything else looks just fine.
For example, if I have two repos (remove-suffix is enabled):
/foo
/foo/bar
http://cgit/foo/bar/ is interpreted as "repository 'foo', command 'bar'"
instead of "repository 'foo/bar'"
The check in parse_user that eventually makes it into committer_date and
tagger_date is:
else if (mode == 3 && isdigit(*p)) {
*date = atol(p);
mode++;
}
Since isdigit('-') is always false, date will never be negative. Thus
the sign of this function:
static int cmp_age(int age1, int age2)
{
if (age1 != 0 && age2 != 0)
return age2 - age1;
if (age1 == 0 && age2 == 0)
return 0;
if (age1 == 0)
return +1;
return -1;
}
Will always be the same as the sign of this function:
static inline int cmp_age(int age1, int age2)
{
return age2 - age1;
}

I have a number of repositories that start tagging with just '1' and
count up. Actually references with sting length of one are skipped, this
patch changes that.
If time-to-live is set to zero, we don't need to regenerate the cache
slots on every request. Instead, just skip the caching process and
immediately provide the dynamically generated version of the page.
Setting time-to-live to zero is useful when you want to disable caching
for certain pages.
