John Keeping 30304d8156 log: allow users to follow a file 
Teach the "log" UI to behave in the same way as "git log --follow", when
given a suitable instruction by the user.  The default behaviour remains
to show the log without following renames, but the follow behaviour can
be activated by following a link in the page header.

Follow is not the default because outputting merges in follow mode is
tricky ("git log --follow" will not show merges).  We also disable the
graph in follow mode because the commit graph is not simplified so we
end up with frequent gaps in the graph and many lines that do not
connect with any commits we're actually showing.

We also teach the "diff" and "commit" UIs to respect the follow flag on
URLs, causing the single-file version of these UIs to detect renames.
This feature is needed only for commits that rename the path we're
interested in.

For commits before the file has been renamed (i.e. that appear later in
the log list) we change the file path in the links from the log to point
to the old name; this means that links to commits always limit by the
path known to that commit.  If we didn't do this we would need to walk
down the log diff'ing every commit whenever we want to show a commit.
The drawback is that the "Log" link in the top bar of such a page links
to the log limited by the old name, so it will only show pre-rename
commits.  I consider this a reasonable trade-off since the "Back" button
still works and the log matches the path displayed in the top bar.

Since following renames requires running diff on every commit we
consider, I've added a knob to the configuration file to globally
enable/disable this feature.  Note that we may consider a large number
of commits the revision walking machinery no longer performs any path
limitation so we have to examine every commit until we find a page full
of commits that affect the target path or something related to it.

CGITRC(5)
========
NAME
----
cgitrc - runtime configuration for cgit
SYNOPSIS
--------
Cgitrc contains all runtime settings for cgit, including the list of git
repositories, formatted as a line-separated list of NAME=VALUE pairs. Blank
lines, and lines starting with '#', are ignored.
LOCATION
--------
The default location of cgitrc, defined at compile time, is /etc/cgitrc. At
runtime, cgit will consult the environment variable CGIT_CONFIG and, if
defined, use its value instead.
GLOBAL SETTINGS
---------------
about-filter::
Specifies a command which will be invoked to format the content of
about pages (both top-level and for each repository). The command will
get the content of the about-file on its STDIN, the name of the file
as the first argument, and the STDOUT from the command will be
included verbatim on the about page. Default value: none. See
also: "FILTER API".
agefile::
Specifies a path, relative to each repository path, which can be used
to specify the date and time of the youngest commit in the repository.
The first line in the file is used as input to the "parse_date"
function in libgit. Recommended timestamp-format is "yyyy-mm-dd
hh:mm:ss". You may want to generate this file from a post-receive
hook. Default value: "info/web/last-modified".
auth-filter::
Specifies a command that will be invoked for authenticating repository
access. Receives quite a few arguments, and data on both stdin and
stdout for authentication processing. Details follow later in this
document. If no auth-filter is specified, no authentication is
performed. Default value: none. See also: "FILTER API".
branch-sort::
Flag which, when set to "age", enables date ordering in the branch ref
list, and when set to "name" enables ordering by branch name. Default
value: "name".
cache-root::
Path used to store the cgit cache entries. Default value:
"/var/cache/cgit". See also: "MACRO EXPANSION".
cache-static-ttl::
Number which specifies the time-to-live, in minutes, for the cached
version of repository pages accessed with a fixed SHA1. See also:
"CACHE". Default value: -1".
cache-dynamic-ttl::
Number which specifies the time-to-live, in minutes, for the cached
version of repository pages accessed without a fixed SHA1. See also:
"CACHE". Default value: "5".

Number which specifies the time-to-live, in minutes, for the cached
version of the repository about page. See also: "CACHE". Default
value: "15".
cache-snapshot-ttl::
Number which specifies the time-to-live, in minutes, for the cached
version of snapshots. See also: "CACHE". Default value: "5".
cache-size::
The maximum number of entries in the cgit cache. When set to "0",
caching is disabled. See also: "CACHE". Default value: "0"
case-sensitive-sort::
Sort items in the repo list case sensitively. Default value: "1".
See also: repository-sort, section-sort.
clone-prefix::
Space-separated list of common prefixes which, when combined with a
repository url, generates valid clone urls for the repository. This
setting is only used if `repo.clone-url` is unspecified. Default value:
none.
clone-url::
Space-separated list of clone-url templates. This setting is only
used if `repo.clone-url` is unspecified. Default value: none. See
also: "MACRO EXPANSION", "FILTER API".
commit-filter::
Specifies a command which will be invoked to format commit messages.
The command will get the message on its STDIN, and the STDOUT from the
command will be included verbatim as the commit message, i.e. this can
be used to implement bugtracker integration. Default value: none.
See also: "FILTER API".
commit-sort::
Flag which, when set to "date", enables strict date ordering in the
commit log, and when set to "topo" enables strict topological
ordering. If unset, the default ordering of "git log" is used. Default
value: unset.
css::
Url which specifies the css document to include in all cgit pages.
Default value: "/cgit.css".
email-filter::
Specifies a command which will be invoked to format names and email
address of committers, authors, and taggers, as represented in various
places throughout the cgit interface. This command will receive an
email address and an origin page string as its command line arguments,
and the text to format on STDIN. It is to write the formatted text back
out onto STDOUT. Default value: none. See also: "FILTER API".
embedded::
Flag which, when set to "1", will make cgit generate a html fragment
suitable for embedding in other html pages. Default value: none. See

enable-follow-links::
Flag which, when set to "1", allows users to follow a file in the log
view. Default value: "0".
enable-http-clone::
If set to "1", cgit will act as an dumb HTTP endpoint for git clones.
You can add "http://$HTTP_HOST$SCRIPT_NAME/$CGIT_REPO_URL" to clone-url
to expose this feature. If you use an alternate way of serving git
repositories, you may wish to disable this. Default value: "1".
enable-index-links::

for plaintext blobs printed in the tree view. Default value: "1".
enable-git-config::
Flag which, when set to "1", will allow cgit to use git config to set
any repo specific settings. This option is used in conjunction with
"scan-path", and must be defined prior, to augment repo-specific
settings. The keys gitweb.owner, gitweb.category, and gitweb.description
will map to the cgit keys repo.owner, repo.section, and repo.desc,
respectively. All git config keys that begin with "cgit." will be mapped
to the corresponding "repo." key in cgit. Default value: "0". See also:
scan-path, section-from-path.
favicon::
Url used as link to a shortcut icon for cgit. It is suggested to use
the value "/favicon.ico" since certain browsers will ignore other
values. Default value: "/favicon.ico".
footer::
The content of the file specified with this option will be included
verbatim at the bottom of all pages (i.e. it replaces the standard
"generated by..." message. Default value: none.

verbatim above the repository index. This setting is deprecated, and
will not be supported by cgit-1.0 (use root-readme instead). Default
value: none.
index-info::
The content of the file specified with this option will be included
verbatim below the heading on the repository index page. This setting
is deprecated, and will not be supported by cgit-1.0 (use root-desc
instead). Default value: none.
local-time::
Flag which, if set to "1", makes cgit print commit and tag times in the
servers timezone. Default value: "0".
logo::
Url which specifies the source of an image which will be used as a logo
on all cgit pages. Default value: "/cgit.png".
logo-link::
Url loaded when clicking on the cgit logo image. If unspecified the
calculated url of the repository index page will be used. Default
value: none.
owner-filter::
Specifies a command which will be invoked to format the Owner
column of the main page. The command will get the owner on STDIN,
and the STDOUT from the command will be included verbatim in the
table. This can be used to link to additional context such as an
owners home page. When active this filter is used instead of the
default owner query url. Default value: none.
See also: "FILTER API".
max-atom-items::
Specifies the number of items to display in atom feeds view. Default
value: "10".

Specifies the maximum size of a blob to display HTML for in KBytes.
Default value: "0" (limit disabled).
max-stats::
Set the default maximum statistics period. Valid values are "week",
"month", "quarter" and "year". If unspecified, statistics are
disabled. Default value: none. See also: "repo.max-stats".
mimetype.<ext>::
Set the mimetype for the specified filename extension. This is used
by the `plain` command when returning blob content.
mimetype-file::
Specifies the file to use for automatic mimetype lookup. If specified
then this field is used as a fallback when no "mimetype.<ext>" match is
found. If unspecified then no such lookup is performed. The typical file
to use on a Linux system is /etc/mime.types. The format of the file must
comply to:
- a comment line is an empty line or a line starting with a hash (#),
optionally preceded by whitespace
- a non-comment line starts with the mimetype (like image/png), followed
by one or more file extensions (like jpg), all separated by whitespace
Default value: none. See also: "mimetype.<ext>".
module-link::
Text which will be used as the formatstring for a hyperlink when a
submodule is printed in a directory listing. The arguments for the
formatstring are the path and SHA1 of the submodule commit. Default
value: none.

deprecated, and will not be honored starting with cgit-1.0. Default
value: "0".
noplainemail::
If set to "1" showing full author email addresses will be disabled.
Default value: "0".
noheader::
Flag which, when set to "1", will make cgit omit the standard header
on all pages. Default value: none. See also: "embedded".
project-list::
A list of subdirectories inside of scan-path, relative to it, that
should loaded as git repositories. This must be defined prior to
scan-path. Default value: none. See also: scan-path, "MACRO
EXPANSION".
readme::
Text which will be used as default value for "repo.readme". Multiple
config keys may be specified, and cgit will use the first found file
in this list. This is useful in conjunction with scan-path. Default
value: none. See also: scan-path, repo.readme.
remove-suffix::
If set to "1" and scan-path is enabled, if any repositories are found
with a suffix of ".git", this suffix will be removed for the url and
name. This must be defined prior to scan-path. Default value: "0".
See also: scan-path.
renamelimit::
Maximum number of files to consider when detecting renames. The value
"-1" uses the compiletime value in git (for further info, look at
`man git-diff`). Default value: "-1".
repo.group::
Legacy alias for "section". This option is deprecated and will not be
supported in cgit-1.0.
repository-sort::
The way in which repositories in each section are sorted. Valid values
are "name" for sorting by the repo name or "age" for sorting by the
most recently updated repository. Default value: "name". See also:
section, case-sensitive-sort, section-sort.

The content of the file specified with this option will be included
verbatim below the "about" link on the repository index page. Default
value: none.
root-title::
Text printed as heading on the repository index page. Default value:
"Git Repository Browser".
scan-hidden-path::
If set to "1" and scan-path is enabled, scan-path will recurse into
directories whose name starts with a period ('.'). Otherwise,
scan-path will stay away from such directories (considered as
"hidden"). Note that this does not apply to the ".git" directory in
non-bare repos. This must be defined prior to scan-path.
Default value: 0. See also: scan-path.
scan-path::
A path which will be scanned for repositories. If caching is enabled,
the result will be cached as a cgitrc include-file in the cache
directory. If project-list has been defined prior to scan-path,
scan-path loads only the directories listed in the file pointed to by
project-list. Be advised that only the global settings taken
before the scan-path directive will be applied to each repository.
Default value: none. See also: cache-scanrc-ttl, project-list,
"MACRO EXPANSION".
section::
The name of the current repository section - all repositories defined
after this option will inherit the current section name. Default value:
none.
section-sort::
Flag which, when set to "1", will sort the sections on the repository
listing by name. Set this flag to "0" if the order in the cgitrc file should
be preserved. Default value: "1". See also: section,
case-sensitive-sort, repository-sort.
section-from-path::
A number which, if defined prior to scan-path, specifies how many
path elements from each repo path to use as a default section name.
If negative, cgit will discard the specified number of path elements
above the repo directory. Default value: "0".
side-by-side-diffs::
If set to "1" shows side-by-side diffs instead of unidiffs per
default. Default value: "0".
snapshots::
Text which specifies the default set of snapshot formats that cgit
generates links for. The value is a space-separated list of zero or
more of the values "tar", "tar.gz", "tar.bz2", "tar.xz" and "zip".
Default value: none.
source-filter::
Specifies a command which will be invoked to format plaintext blobs
in the tree view. The command will get the blob content on its STDIN
and the name of the blob as its only command line argument. The STDOUT
from the command will be included verbatim as the blob contents, i.e.
this can be used to implement e.g. syntax highlighting. Default value:
none. See also: "FILTER API".
summary-branches::
Specifies the number of branches to display in the repository "summary"
view. Default value: "10".
summary-log::
Specifies the number of log entries to display in the repository
"summary" view. Default value: "10".
summary-tags::
Specifies the number of tags to display in the repository "summary"
view. Default value: "10".
strict-export::
Filename which, if specified, needs to be present within the repository
for cgit to allow access to that repository. This can be used to emulate
gitweb's EXPORT_OK and STRICT_EXPORT functionality and limit cgit's
repositories to match those exported by git-daemon. This option must
be defined prior to scan-path.
virtual-root::
Url which, if specified, will be used as root for all cgit links. It
will also cause cgit to generate 'virtual urls', i.e. urls like
'/cgit/tree/README' as opposed to '?r=cgit&p=tree&path=README'. Default
value: none.
NOTE: cgit has recently learned how to use PATH_INFO to achieve the
same kind of virtual urls, so this option will probably be deprecated.

a colon. For example, "master:docs/readme.mkd". If the value begins
with a colon, i.e. ":docs/readme.rst", the default branch of the
repository will be used. Sharing any file will expose that entire
directory tree to the "/about/PATH" endpoints, so be sure that there
are no non-public files located in the same directory as the readme
file. Default value: <readme>.

setting specified for each repo. Default value: none.
REPOSITORY-SPECIFIC CGITRC FILE
-------------------------------
When the option "scan-path" is used to auto-discover git repositories, cgit
will try to parse the file "cgitrc" within any found repository. Such a
repo-specific config file may contain any of the repo-specific options
described above, except "repo.url" and "repo.path". Additionally, the "filter"
options are only acknowledged in repo-specific config files when
"enable-filter-overrides" is set to "1".
Note: the "repo." prefix is dropped from the option names in repo-specific
config files, e.g. "repo.desc" becomes "desc".
FILTER API
----------
By default, filters are separate processes that are executed each time they
are needed. Alternative technologies may be used by prefixing the filter
specification with the relevant string; available values are:
'exec:'::
The default "one process per filter" mode.
'lua:'::
Executes the script using a built-in Lua interpreter. The script is
loaded once per execution of cgit, and may be called multiple times
during cgit's lifetime, making it a good choice for repeated filters
such as the 'email filter'. It responds to three functions:
'filter_open(argument1, argument2, argument3, ...)'::
This is called upon activation of the filter for a particular
set of data.
'filter_write(buffer)'::
This is called whenever cgit writes data to the webpage.
'filter_close()'::
This is called when the current filtering operation is
completed. It must return an integer value. Usually 0
indicates success.
Additionally, cgit exposes to the Lua the following built-in functions:
'html(str)'::
Writes 'str' to the webpage.
'html_txt(str)'::
HTML escapes and writes 'str' to the webpage.
'html_attr(str)'::
HTML escapes for an attribute and writes "str' to the webpage.
'html_url_path(str)'::
URL escapes for a path and writes 'str' to the webpage.
'html_url_arg(str)'::
URL escapes for an argument and writes 'str' to the webpage.
'html_include(file)'::
Includes 'file' in webpage.
Parameters are provided to filters as follows.
about filter::
This filter is given a single parameter: the filename of the source
file to filter. The filter can use the filename to determine (for
example) the type of syntax to follow when formatting the readme file.
The about text that is to be filtered is available on standard input
and the filtered text is expected on standard output.
commit filter::
This filter is given no arguments. The commit message text that is to
be filtered is available on standard input and the filtered text is
expected on standard output.
email filter::
This filter is given two parameters: the email address of the relevent
author and a string indicating the originating page. The filter will
then receive the text string to format on standard input and is
expected to write to standard output the formatted text to be included
in the page.
owner filter::
This filter is given no arguments. The owner text is avilable on
standard input and the filter is expected to write to standard
output. The output is included in the Owner column.
source filter::
This filter is given a single parameter: the filename of the source
file to filter. The filter can use the filename to determine (for
example) the syntax highlighting mode. The contents of the source
file that is to be filtered is available on standard input and the
filtered contents is expected on standard output.
auth filter::
The authentication filter receives 12 parameters:
- filter action, explained below, which specifies which action the
filter is called for
- http cookie
- http method
- http referer
- http path
- http https flag
- cgit repo
- cgit page
- cgit url
- cgit login url
When the filter action is "body", this filter must write to output the
HTML for displaying the login form, which POSTs to the login url. When
the filter action is "authenticate-cookie", this filter must validate
the http cookie and return a 0 if it is invalid or 1 if it is invalid,
in the exit code / close function. If the filter action is
"authenticate-post", this filter receives POST'd parameters on
standard input, and should write a complete CGI response, preferably
with a 302 redirect, and write to output one or more "Set-Cookie"
HTTP headers, each followed by a newline.
Please see `filters/simple-authentication.lua` for a clear example
script that may be modified.
All filters are handed the following environment variables:
- CGIT_REPO_URL (from repo.url)
- CGIT_REPO_NAME (from repo.name)
- CGIT_REPO_PATH (from repo.path)
- CGIT_REPO_OWNER (from repo.owner)
- CGIT_REPO_DEFBRANCH (from repo.defbranch)
- CGIT_REPO_SECTION (from repo.section)
- CGIT_REPO_CLONE_URL (from repo.clone-url)
If a setting is not defined for a repository and the corresponding global
setting is also not defined (if applicable), then the corresponding
environment variable will be unset.
MACRO EXPANSION
---------------
The following cgitrc options support a simple macro expansion feature,
where tokens prefixed with "$" are replaced with the value of a similarly
named environment variable:
- cache-root
- include
- project-list
- scan-path
Macro expansion will also happen on the content of $CGIT_CONFIG, if
defined.
One usage of this feature is virtual hosting, which in its simplest form
can be accomplished by adding the following line to /etc/cgitrc:
include=/etc/cgitrc.d/$HTTP_HOST
The following options are expanded during request processing, and support
the environment variables defined in "FILTER API":
- clone-url
- repo.clone-url
CACHE
------
All cache ttl values are in minutes. Negative ttl values indicate that a page
type will never expire, and thus the first time a URL is accessed, the result
will be cached indefinitely, even if the underlying git repository changes.
Conversely, when a ttl value is zero, the cache is disabled for that
particular page type, and the page type is never cached.
