2015-11-24filter: avoid integer overflow in authenticate_postJason A. Donenfeld-1/+1
ctx.env.content_length is an unsigned int, coming from the CONTENT_LENGTH environment variable, which is parsed by strtoul. The HTTP/1.1 spec says that "any Content-Length greater than or equal to zero is a valid value." By storing this into an int, we potentially overflow it, resulting in the following bounding check failing, leading to a buffer overflow.

2015-08-14cgit: use cgit_print_error_page() where appropriateJohn Keeping-20/+7
These are more-or-less one-to-one translations but in the final hunk we gain an HTTP error code where we used to send "200 OK", which is an improvement. Signed-off-by: John Keeping <john@keeping.me.uk>
2015-08-12log: allow users to follow a fileJohn Keeping-0/+4
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.

2015-01-29Add repo.hide and repo.ignoreLukas Fleischer-0/+6
These options can be used to hide a repository from the index or completely ignore a repository, respectively. They are particularly useful when used in combination with scan-path. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>

2014-12-13Change "ss" diff flag to an enumJohn Keeping-4/+8
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.

2014-08-07Always check if README exists in choose_readme()Lukas Fleischer-6/+0
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. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
2014-06-28git: update for git 2.0Christian Hesse-13/+13
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.
2014-02-20Add a cache-snapshot-ttl configuration variableLukas Fleischer-0/+6
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).

2014-01-16auth: add basic authentication filter frameworkJason A. Donenfeld-2/+94
This leverages the new lua support. See filters/simple-authentication.lua for explaination of how this works. There is also additional documentation in cgitrc.5.txt. Though this is a cookie-based approach, cgit's caching mechanism is preserved for authenticated pages. Very plugable and extendable depending on user needs. The sample script uses an HMAC-SHA1 based cookie to store the currently logged in user, with an expiration date. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2014-01-14filter: basic write hooking infrastructureJason A. Donenfeld-0/+2
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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2014-01-14filter: allow for cleanup hook for filter typesJason A. Donenfeld-0/+1
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(). Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2014-01-14filter: add fprintf_filter functionJohn Keeping-3/+3

Pages like /commit?h=wip&id=8a335ce618ba77fbf05148d6f8be17bd48ba4340 were being marked as dynamic, because of h=wip, when it should be static, because of id=. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2013-08-12cache: document negative ttls and add about ttlJason A. Donenfeld-3/+12
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. Signed-off-by: Jason A.

2013-05-25readme: Accept multiple candidates and test them.Jason A. Donenfeld-0/+35
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. Signed-off-by: Jason A.

2013-04-10cgit.c: Do not restore unset environment variablesLukas Fleischer-2/+4
getenv() returns a NULL pointer if the specified variable name cannot be found in the environment. However, some setenv() implementations crash if a NULL pointer is passed as second argument. Only restore variables that are not NULL. See commit d96d2c98ebc4c2d3765f5b35c4142e0e828a421b for a related patch. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
2013-04-08Do not load user or system gitconfig and gitattributesJason A. Donenfeld-0/+24
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 may have set for his own /usr/bin/git usage. This fixes a fatal error introduced with git 1.8, whereupon git would fatally exit when failing to access particular files. The result of this is that only repo-local configuration files are accessed: zx2c4@thinkpad ~/Projects/cgit $ HOME=/root QUERY_STRING="url=foo/log" CGIT_CONFIG=tests/trash/cgitrc strace -e access ./cgit >/dev/null access("/etc/ld.so.preload", R_OK) = -1 ENOENT (No such file or directory) access("repos/foo/.git/objects", X_OK) = 0 access("repos/foo/.git/refs", X_OK) = 0 access("repos/foo/.git/config", R_OK) = 0 access("repos/foo/.git/config", R_OK) = 0 access("repos/foo/.git/objects/b3/bafdbf0183f4897ef8b1319cb8c490ed54717e", F_OK) = 0 access("repos/foo/.git/objects/b3/bafdbf0183f4897ef8b1319cb8c490ed54717e", F_OK) = 0 access("repos/foo/.git/objects/b3/bafdbf0183f4897ef8b1319cb8c490ed54717e", F_OK) = 0 access("repos/foo/.git/objects/b3/bafdbf0183f4897ef8b1319cb8c490ed54717e", F_OK) = 0 +++ exited with 0 +++ Reported-by: Ferry Huberts <ferry.huberts@pelagic.nl> Tested-by: Jason A.
