* plain: don't append charset for binary MIME typesJohn Keeping2014-01-08-3/+8
| | | | | | | | | | | | | When outputting the Content-Type HTTP header we print the MIME type and then append "; charset=<charset>" if the charset variable is non-null. We don't want a charset when we have selected "application/octet-stream" or when the user has specified a custom MIME type, since they may have specified their own charset. To avoid this, make sure we set the page's charset to NULL in ui-plain before we generate the HTTP headers.

* ui-log.c: Several simplificationsLukas Fleischer2014-01-08-19/+9
| | | | | | | | * Use argv_array_pushf() for inserting formatted strings. * Remove unneeded static strings. * Replace "if" by "else if" for readability and speed. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* Use argv_array in place of vectorLukas Fleischer2014-01-08-75/+15
| | | | | | | | | Instead of using our own vector implementation, use argv_array from Git which has been specifically designed for dynamic size argv arrays. Drop vector.h and vector.c which are no longer needed. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>

* scan-tree.c: Remove unused macroLukas Fleischer2014-01-08-2/+0
| | | | | | | This is no longer needed since commit fb3655df (use struct strbuf instead of static buffers, 2013-04-06). Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-shared: Drop filepair_cb_raw() and helperLukas Fleischer2013-09-14-73/+0
| | | | | | | | Remove filepair_cb_raw() and all related functions. These are no longer needed. We now use Git's internal functions for raw diff formatting everywhere. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-diff: Use diff_tree_sha1() for raw diff formattingLukas Fleischer2013-09-14-2/+21
| | | | | | | Use Git's internal diff_tree_sha1() function for the /rawdiff/ command instead of trying to recreate this functionality. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* tests/: Add t0110-rawdiff.shLukas Fleischer2013-08-26-0/+42
| | | | | | This adds some basic tests for the /rawdiff/ command. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* t0108: Add tests for revision rangesLukas Fleischer2013-08-26-0/+17
| | | | | | Add tests to check whether generating multiple patches at once works. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* t0108: Compare output with git-format-patch(1)Lukas Fleischer2013-08-26-0/+7
| | | | Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-patch.c: Add additional newline after each patchLukas Fleischer2013-08-26-3/+3
| | | | | | For consistency with git-format-patch(1). Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-patch.c: Fix signature delimiterLukas Fleischer2013-08-26-1/+1
| | | | | | | Add a missing space after the "--" marker that introduces the patch signature. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* t0108: Avoid unnecessary fork()Lukas Fleischer2013-08-26-1/+1
| | | | | | | Use `git rev-list --max-parents=0 HEAD` instead of `git rev-list HEAD | tail -1` to get the root commit. This works since Git 1.7.4.2. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* git: update to 1.8.4John Keeping2013-08-26-1/+1
| | | | | | No code changes required, just bump the submodule and makefile versions. Signed-off-by: John Keeping <john@keeping.me.uk>
* ui-patch.c: Fix formatting for merge commitsLukas Fleischer2013-08-22-0/+1
| | | | | | | Add max_parents = 1 to the revision walk in order to make sure we do not include the footer signature twice for merge commits. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-patch: Rename variablesLukas Fleischer2013-08-20-17/+19
| | | | | | | Rename parameters and local variables to match those from ui-diff. Also, convert a "char *" to "const char *". Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* Allow for creating patch seriesLukas Fleischer2013-08-20-7/+20
| | | | | | | | | This allows for specifying a revision range using the id2 parameter of /patch/. The output that is produced is similar to $ git format-patch --stdout id2..id Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-patch.c: Use log_tree_commit() to generate diffsLukas Fleischer2013-08-20-23/+28
| | | | | | | | | Instead of using our own formatting, use log_tree_commit() from Git to create patches. This removes unnecessary duplicate code and also fixes a bug with e-mail address formatting that existed in our own implementation. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-diff: Check the return value of get_sha1()Lukas Fleischer2013-08-20-14/+9
| | | | | | | | | Sync with what we do everywhere else and check the return value of get_sha1() instead of calling sha1_object_info() to validate the object. Note that we later call lookup_commit_reference(), which checks that both SHA1 values refer to commits, anyway. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* cmd.c: Add a "rawdiff" commandLukas Fleischer2013-08-16-0/+6
| | | | | | | | | This can be used to generate raw diffs between arbitrary revisions using something like /rawdiff/?id=v0.9&id2=v0.9.1 Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* Allow for creating raw diffs with cgit_print_diff()Lukas Fleischer2013-08-16-4/+12
| | | | | | | This adds a parameter to cgit_print_diff() to create raw diffs, using the same format as `git diff <commit>`. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* Extract filepair_cb from ui-patch.cLukas Fleischer2013-08-16-73/+74
| | | | | | | | | | | Move filepair_cb() from ui-patch.c to ui-shared.c and rename it to filepair_cb_raw(). This callback will be used in ui-diff.c in a follow-up patch. Note that it is not straightforward to extract filepair_cb() from ui-diff.c which is why it is not done here as well. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>

* Fix section-from-path > 1Lukas Fleischer2013-08-12-4/+4
| | | | | | | | | | | When having found the first path separator occurrence at position i, we invoked strchr() on the same position i in subsequent iterations resulting in the same path separator being returned by strchr() over and over again. Increase the position by one to skip the occurrence that has just been found and advance to the next separator.

* Makefile: Change default prefix to "/usr/local"Lukas Fleischer2013-08-12-1/+1
| | | | | | | Locally installed packages are usually installed to /usr/local. Packagers can use `make prefix=/usr` to get back the old behavior. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* Use strbuf for reading configuration filesLukas Fleischer2013-08-12-31/+35
| | | | | | | | | | | Use struct strbuf from Git instead of fixed-size buffers to remove the limit on the length of configuration file lines and refactor read_config_line() to improve readability. Note that this also fixes a buffer overflow that existed with the original fixed-size buffer implementation. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>

* cache: id means static, even if head is specified tooJason A. Donenfeld2013-08-12-3/+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>
* cache: document negative ttls and add about ttlJason A. Donenfeld2013-08-12-13/+31
| | | | | | | | | | | | | | 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. Donenfeld <Jason@zx2c4.com>
* robots.txt: disallow access to snapshotsJason A. Donenfeld2013-08-12-0/+4
| | | | | | | | | | | | My dmesg is filled with the oom killer bringing down processes while the Bingbot downloads every snapshot for every commit of the Linux kernel in tar.xz format. Sure, I should be running with memory limits, and now I'm using cgroups, but a more general solution is to prevent crawlers from wasting resources like that in the first place.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ui-summary: Disallow directory traversalJason A. Donenfeld2013-05-25-0/+16
| | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* readme: Accept multiple candidates and test them.Jason A. Donenfeld2013-05-25-31/+95
| | | | | | | | | | | 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. Donenfeld <Jason@zx2c4.com>
* ui-summary: Pass filename to about-filterJason A. Donenfeld2013-05-25-8/+22
| | | | | | | | | | This gives the about-filter API the same semantics as source-filter, where the filter receives the filename so it can decide what to do next with it. While we're at it, plug a memory leak. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* ui-summary: Use default branch for readme if : prefixJason A. Donenfeld2013-05-25-2/+9

* cgit.c: Do not reset HOME after unsetting it.Jason A. Donenfeld2013-05-25-22/+0
| | | | | | | | | | The number of odd cases in which git will try to read config is far too great to keep putting a bandaid over each one, so we'll just unset it. If it turns out that scripts really liked to know about $HOME, we can always reset it in the filter forks. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* cache.c: cache ls_cache output properlyJohn Keeping2013-05-22-7/+14
| | | | | | | | | By using the standard library's printf, cache_ls does not redirect its output to the cache when we change the process' stdout file descriptor to point to the cache file. Fix this by using "htmlf" in the same way that we do for writing HTTP headers. Signed-off-by: John Keeping <john@keeping.me.uk>
* tests: introduce strip_header() helper functionJohn Keeping2013-05-22-2/+10
| | | | | | | | This means that we can avoid hardcoding the number of headers we expect CGit to generate in test cases and simply remove whatever headers happen to by there when we are checking body content. Signed-off-by: John Keeping <john@keeping.me.uk>
