over again. Increase the position by one to skip the occurrence that has
just been found and advance to the next separator.

61ff10065b cache: document negative ttls and add about ttl
We've long supported negative ttls, for infinite cache, except the
documentation incorrectly showed one of our defaults as being 5 and not
-1. As well, with a negative ttl, we were actually making the HTTP
expired header go backwards. This changes it to go ahead ten years
instead.

Further, we add an cache-about-ttl option to set a different ttl for
about pages, which are now increasingly being filtered through markdown
or just sent statically anyway.

989d251384 CGIT-0.9.2
Features:
- update to git v1.8.3.
- expanded set of default filters to include markdown, restructuredtext, and
  man pages.
- better sample configuration file in man page.
- "readme" may now be specified multiple times, and cgit will choose the first
  one it finds.
- "readme" no longer needs a branch name. If prefixed with simply ":" it will
  use the default branch.
- "branch-sort" allowing branches to be sorted either by "age" or "name", for
  kernel.org.
- "enable-index-owner" allowing the owner column to be disabled in the index
  page.
- print submodule revision next to submodule link.
- integrate more closely with git apis, such as strbuf.
- rely on git test harness and git makefiles.
- more robust test suite.
- more rebust makefile dependency accounting.
- pager navigation is now unordered list.
- span tag wraps commit directions.

Behavior changes:
- HOME is no longer passed as an environment variable to any filter api
  scripts.
- "about-filter" now receives the filename being filtered as argv[1]. This may
  disrupt existing scripts, so adjust accordingly.
- gitconfig and gitattributes are no longer loaded from any system directories
  or home directories.

Security:
- CVE-2013-2117: disallow directory traversal when readme is set to filesystem
  path.

Bug fixes:
- ssdiff now correctly manages tab expansion.
- support unannotated tags in http git clone.
- lots of cleanups of global variables and memory leaks.
- do not rely on gettext/libintl.
- better C standard compliance.
- make several functions and variables static.
- improved constification.
- remove unused functions.
- fix colspan values to correct width.
- fix out-of-bounds memory accesses with virtual_root="".
- cache repo config more precisely.
- die when write fails.

fe36f84d84 ui-summary: Disallow directory traversal
Using the url= query string, it was possible request arbitrary files
from the filesystem if the readme for a given page was set to a
filesystem file. The following request would return my /etc/passwd file:

http://git.zx2c4.com/?url=/somerepo/about/../../../../etc/passwd
http://data.zx2c4.com/cgit-directory-traversal.png

This fix uses realpath(3) to canonicalize all paths, and then compares
the base components.

This fix introduces a subtle timing attack, whereby a client can check
whether or not strstr is called using timing measurements in order
to determine if a given file exists on the filesystem.

This fix also does not account for filesystem race conditions (TOCTOU)
in resolving symlinks.

cd4c77d989 readme: Accept multiple candidates and test them.
The readme variable may now contain multiple space deliminated entries,
which per usual are either a filepath or a git ref filepath. If multiple
are specified, cgit will now select the first one in the list that
exists. This is to make it easier to specify multiple default readme
types in the main cgitrc file and have them automatically get applied to
each repo based on what exists.

c2b79dd8e0 Makefile: fix parallel "make test"
When building the "test" target we depend on both cgit and building the
Git tools.  By doing this with two targets we end up running make in the
git/ directory twice, concurrently if using parallel make, which causes
us to build more than we need and potentially builds incorrectly if
multi-step build-then-move operations overlap.

Fix this by instead calling back into the makefile so that we alter the
"cgit" target to also build the Git tools.

8d07ad3388 t0001: validate Git -rcN version numbers correctly
When creating the GIT-VERSION-FILE that we use to test that the version
of Git in git/ is the same as in the CGit Makefile, Git applies the
transform "s/-/./g" to the version string.  This doesn't affect released
versions but does change RC version numbers such as 1.8.3-rc0.

While CGit should only refer to a released Git version in general, it is
useful to developers who want to test upcoming Git releases if the tests
do work with RCs, so change t0001 to apply the same transform to our
Makefile version before comparing it to the contents of
GIT-VERSION-FILE.
