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.

prefixcmp() and suffixcmp() have been remove, functionality is now
provided by starts_with() and ends_with(). Retrurn values have been

Everything else looks just fine.
This can be used to specify the TTL for snapshots. Snapshots are usually
static and do not ever change. On the other hand, tarball generation is
CPU intensive.
One use case of this setting (apart from increasing the lifetime of
snapshot cache slots) is caching of snapshots while disabling the cache
for static/dynamic HTML pages (by setting TTL to zero for everything
except for snapshot requests).

Though this is a cookie-based approach, cgit's caching mechanism is

Filters can now call hook_write and unhook_write if they want to
redirect writing to stdout to a different function. This saves us from
potential file descriptor pipes and other less efficient mechanisms.
We do this instead of replacing the call in html_raw because some places
stdlib's printf functions are used (ui-patch or within git itself),
which has its own internal buffering, which makes it difficult to
interlace our function calls. So, we dlsym libc's write and then
override it in the link stage.
While we're at it, we move considerations of argument count into the
generic new filter handler.

At some point, we're going to want to do lazy deallocation of filters.
For example, if we implement lua, we'll want to load the lua runtime
once for each filter, even if that filter is called many times.
Similarly, for persistent exec filters, we'll want to load it once,
despite many open_filter and close_filter calls, and only reap the child
process at the end of the cgit process. For this reason, we add here a
cleanup function that is called at the end of cgit's main().

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

which per usual are either a filepath or a git ref filepath. If multiple

While doing any kind of git loading, unset HOME variables and set
NOSYSTEM variables so that cgit does not load any settings that a user

Use "struct strbuf" from Git to remove the limit on file path length.
Notes on scan-tree:
This is slightly involved since I decided to pass the strbuf into
add_repo() and modify if whenever a new file name is required, which
should avoid any extra allocations within that function. The pattern
there is to append the filename, use it and then reset the buffer to its
original length (retaining a trailing '/').
Notes on ui-snapshot:
Since write_archive modifies the argv array passed to it we
copy the argv_array values into a new array of char* and then free the
original argv_array structure and the new array without worrying about
what the values now look like.

The CGit configuration variable virtual_root is normalized so that it
does not have a trailing '/' character, but it is allowed to be empty
(the empty string and NULL have different meanings here) and there is
code that is insufficiently cautious when checking if it ends in a '/':
if (virtual_root[strlen(virtual_root) - 1] != '/')
Clearly this check is redundant, but rather than simply removing it we
get a slight efficiency improvement by switching the normalization so
that the virtual_root variable always ends in '/'. Do this with a new
"ensure_end" helper.

After some back and forth with Jamie and René, it looks like the git
config semantics are going to be like this:
- gitweb.category maps to the cgit repo config key "section"
- gitweb.description maps to the cgit repo config key "desc"
- gitweb.owner maps to the cgit repo config key "owner"
- cgit.* maps to all cgit repo config keys
This option can be enabled with "enable-git-config=1", and replaces
all previous "enable-gitweb-*" config keys.
The order of operations is as follows:
- git config settings are applied in the order that they exist in
the git config file
- if the owner is not set from git config, get the owner using the
usual getpwuid call
- if the description is not set from git config, look inside the
static $path/description file
- if section-from-path=1, override whatever previous settings were
inside of git config using the section-from-path logic
- parse $path/cgitrc for local repo.* settings, that override all
previous settings
This makes it possible to activate the enable_commit_graph,
enable_log_filecount, and enable_log_linecount for individual
repositories, even if the global setting is "0" (default).
The commit that introduced the broken behavior was e189344, and the
commit message of that makes it clear that this wasn't the intended
behavior.
