* ui-shared: don't use an integer as a NULL pointerJohn Keeping2015-03-09-1/+1
| | | | Signed-off-by: John Keeping <john@keeping.me.uk>
* ui-shared: avoid initializing static variable to zeroJohn Keeping2015-03-09-1/+1
| | | | | | | | | Sparse complains that we are using a plain integer as a NULL pointer here, but in fact we do not have to specify a value for this variable at all since it has static storage duration and thus will be initialized to NULL by the compiler.

* tag: reference with "h" instead of "id"John Keeping2015-01-19-4/+4
| | | | | | | | | | | | | | | When clicking on "log" from a tag we end up showing the log of whatever branch we used to reach the tag. If the tag doesn't point onto a branch then the tagged commit won't appear in this output. By linking to tags with the head parameter instead of the "id" parameter the log link will show the log of the tag. This is clearly desirable when the tag has been reached from the refs UI and changing the behaviour for tag decorations makes them match branch decorations where log -> decoration -> log shows the log of the decoration.

* footer: link back to cgit home pageJason A. Donenfeld2014-12-23-1/+1
| | | | | The footer has always been overrideable using the footer= in cgitrc, so this won't anger anybody who cares about their footer.

* ui-shared: add rel-vcs microformat links to HTML headerJohn Keeping2014-12-23-0/+11
| | | | | | As described at https://joeyh.name/rfc/rel-vcs/. Signed-off-by: John Keeping <john@keeping.me.uk>
* Extract clone URL printing to ui-shared.cJohn Keeping2014-12-23-0/+37
| | | | | | | | This will allow us to reuse the same logic to add clone URL <link/> elements to the header of all repo-specific pages in order to support the rel-vcs microformat. Signed-off-by: John Keeping <john@keeping.me.uk>
* Change "ss" diff flag to an enumJohn Keeping2014-12-13-4/+4
| | | | | | | | | | | 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.

* ui-shared: remove toggle_ssdiff arg to cgit_diff_link()John Keeping2014-12-13-4/+4
| | | | | | | This argument is never used with a value other than zero, so remove it and simplify the code. Signed-off-by: John Keeping <john@keeping.me.uk>
* ui-shared: remove toggle_ssdiff arg to cgit_commit_link()John Keeping2014-12-13-6/+5

* git: update for git 2.0Christian Hesse2014-06-28-1/+1
| | | | | | | 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.
* ui-shared: do not allow negative minutesJason A. Donenfeld2014-01-17-0/+2
| | | | | | | Do to timestamp differences, sometimes cgit would should "-0 min", which doesn't make any sense. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_print_http_headers() * cgit_print_docstart() * cgit_print_pageheader() Remove context parameter from all commands Drop the context parameter from the following functions (and all static helpers used by them) and use the global context instead: * cgit_get_cmd() * All cgit command functions. * cgit_clone_info() * cgit_clone_objects() * cgit_clone_head() * cgit_print_plain() * cgit_show_stats() In initialization routines, use the global context variable instead of passing a pointer around locally. Remove callback data parameter for cache slots This is no longer needed since the context is always read from the global context variable. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* auth: have cgit calculate login addressJason A. Donenfeld2014-01-16-0/+8
| | | | | | | This way we're sure to use virtual root, or any other strangeness encountered. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* auth: add basic authentication filter frameworkJason A. Donenfeld2014-01-16-12/+16
| | | | | | | | | | | | | | | | 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>
* ui-shared: URL-escape script_nameJohn Keeping2014-01-12-2/+2
| | | | | | | | As far as I know, there is no requirement that $SCRIPT_NAME contain only URL-safe characters, so we need to make sure that any special characters are escaped. Signed-off-by: John Keeping <john@keeping.me.uk>
* Replace most uses of strncmp() with prefixcmp()Lukas Fleischer2014-01-10-1/+1

* ui-shared: Drop filepair_cb_raw() and helperLukas Fleischer2013-09-14-72/+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>
* Extract filepair_cb from ui-patch.cLukas Fleischer2013-08-16-0/+72
| | | | | | | | | | | 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>

* use struct strbuf instead of static buffersJohn Keeping2013-04-08-28/+35
| | | | | | | | | | | | | | | | | | | 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. Signed-off-by: John Keeping <john@keeping.me.uk>
* Convert cgit_print_error to a variadic functionJohn Keeping2013-04-08-2/+13
| | | | | | | | | This removes many uses of "fmt" which uses a fixed size static pool of fixed size buffers. Instead of relying on these, we now pass around argument lists for as long as possible before using a strbuf to render content of an arbitrary size. Signed-off-by: John Keeping <john@keeping.me.uk>
* Fix out-of-bounds memory accesses with virtual_root=""John Keeping2013-04-08-9/+5
| | | | | | | | | | | | | | | | 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. Signed-off-by: John Keeping <john@keeping.me.uk>
* Always #include corresponding .h in .c filesJohn Keeping2013-04-08-0/+1
| | | | | | | | | | | | While doing this, remove declarations from header files where the corresponding definition is declared "static" in order to avoid build errors. Also re-order existing headers in ui-*.c so that the file-specific header always comes immediately after "cgit.h", helping with future consistency. Signed-off-by: John Keeping <john@keeping.me.uk>
* Return const char * in cgit_{httpscheme, hosturl, rooturl}()Lukas Fleischer2013-04-08-4/+4
| | | | | | | | | | | | The return values of these functions are essentially constant and should never be modified. Note that this will introduce a compiler warning when we try to free the return value of any of these functions. However, given that all of these currently return statically allocated strings in some cases, they need to be refactored before this can be done anyway. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
* ui-shared: squelch compiler warning.Jason A. Donenfeld2013-03-20-0/+1
| | | | | | Since tail is initialized to 0, we will never get a warning on the last if statement, but recent gcc complains anyway. So, we initialize len as well. Future gcc versions should be able to optimize this out anyway.

* | ui-shared: fix return type of cgit_self_linkJohn Keeping2013-03-20-41/+42
|/ | | | | | | | | | | | | | cgit_self_link() is a void function but implements each case it handles by doing "return <another_void_function>" which is not valid C; section 6.8.6.4 of C11 says: A return statement with an expression shall not appear in a function whose return type is void. Fix this by removing the return keywords and converting the final code block into an "else". Signed-off-by: John Keeping <john@keeping.me.uk>

* | Fix segmentation fault in empty repositoryJohn Keeping2012-01-03-1/+1
| | | | | | | | | | | | | | | | | | | | | | When a repository is empty, the ATOM feed link is written in the header, but this involves formatting ctx->qry.head which is NULL in this case. With glibc, vsnprintf formats "%s" with a NULL input as "(null)" but on Solaris this results in a segmentation fault. Since we don't have a meaningful head for the atom feed in an empty repository, it's simplest not to write out the link element at all. Signed-off-by: John Keeping <john@metanate.com>
