2018-07-03snapshot: support tar signature for compressed tarChristian Hesse1-1/+2
This adds support for kernel.org style signatures where the uncompressed tar archive is signed and compressed later. The signature is valid for all tar* snapshots. We have a filter which snapshots may be generated and downloaded. This has to allow tar signatures now even if tar itself is not allowed. To simplify things we allow all signatures.

2018-06-27git: update to v2.18.0Christian Hesse1-1/+1
Update to git version v2.18.0. Required changes follow upstream commits: * Convert find_unique_abbrev* to struct object_id (aab9583f7b5ea5463eb3f653a0b4ecac7539dc94) * sha1_file: convert read_sha1_file to struct object_id (b4f5aca40e6f77cbabcbf4ff003c3cf30a1830c8) * sha1_file: convert sha1_object_info* to object_id (abef9020e3df87c441c9a3a95f592fce5fa49bb9) * object-store: move packed_git and packed_git_mru to object store (a80d72db2a73174b3f22142eb2014b33696fd795) * treewide: rename tree to maybe_tree (891435d55da80ca3654b19834481205be6bdfe33) The changed data types required some of our own functions to be converted to struct object_id: ls_item print_dir print_dir_entry print_object single_tree_cb walk_tree write_tree_link And finally we use new upstream functions that were added for struct object_id: hashcpy -> oidcpy sha1_to_hex -> oid_to_hex Signed-off-by: Christian Hesse <mail@eworm.de> Reviewed-by: John Keeping <john@keeping.me.uk>
2018-06-27snapshot: strip bit from struct cgit_snapshot_formatChristian Hesse1-6/+11
We had a static bit value in struct cgit_snapshot_format. We do not rely on it and things can be calculated on the fly. So strip it. Signed-off-by: Christian Hesse <mail@eworm.de>
2018-06-27snapshot: support archive signaturesJohn Keeping1-1/+75
Read signatures from the notes refs refs/notes/signatures/$FORMAT where FORMAT is one of our archive formats ("tar", "tar.gz", ...). The note is expected to simply contain the signature content to be returned when the snapshot "${filename}.asc" is requested, so the signature for cgit-1.1.tar.xz can be stored against the v1.1 tag with: git notes --ref=refs/notes/signatures/tar.xz add -C "$( gpg --output - --armor --detach-sign cgit-1.1.tar.xz | git hash-object -w --stdin )" v1.1 and then downloaded by simply appending ".asc" to the archive URL.

2017-08-10git: update to v2.14Jeff Smith1-1/+1
Numerous changes were made to git functions to use an object_id structure rather than sending sha1 hashes as raw unsigned character arrays. The functions that affect cgit are: parse_object, lookup_commit_reference, lookup_tag, lookup_tree, parse_tree_indirect, diff_root_tree_sha1, diff_tree_sha1, and format_display_notes. Commit b2141fc (config: don't include config.h by default) made it necessary to that config.h be explicitly included when needed. Commit 07a3d41 (grep: remove regflags from the public grep_opt API) removed one way of specifying the ignore-case grep option. Signed-off-by: Jeff Smith <whydoubt@gmail.com>

2016-10-04ui-snapshot: replace 'unsigned char sha1[20]' with 'struct object_id oid'Christian Hesse1-9/+9
Upstream git is replacing 'unsigned char sha1[20]' with 'struct object_id oid'. We have some code that can be changed independent from upstream. So here we go...
2015-08-14snapshot: don't reimplement cgit_print_error_page()John Keeping1-17/+4
cgit_print_error_page() has the advantage that it sets a suitable HTTP status code for the response. Note that setting "mimetype" is redundant here since it cannot have changed since being initialized in cgit.c::prepare_context(), so we do not need to worry that cgit_print_error_page() does not set it.

2014-01-14filter: add interface layerJohn Keeping1-6/+5
Change the existing cgit_{open,close,fprintf}_filter functions to delegate to filter-specific implementations accessed via function pointers on the cgit_filter object. We treat the "exec" filter type slightly specially here by putting its structure definition in the header file and providing an "init" function to set up the function pointers. This is required so that the ui-snapshot.c code that applies a compression filter can continue to use the filter interface to do so. Signed-off-by: John Keeping <john@keeping.me.uk>
2014-01-12ui-snapshot: set unused cgit_filter fields to zeroJohn Keeping1-4/+4

2013-05-25cgit.c: Do not reset HOME after unsetting it.Jason A. Donenfeld1-9/+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>
2013-04-30ui-snapshot: do not access $HOMEJason A. Donenfeld1-0/+9
It's a bit tedious to have to do this here too. If we encounter other issues with $HOME down the line, I'll look into adding some nice utility functions to handle this, or perhaps giving up on the hope that we could keep $HOME defined for scripts. This commit additionally adds a test case, should the issue surface again. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2013-04-10ui-snapshot.c: Prepend "V" when guessing ref namesLukas Fleischer1-2/+6
In cgit_print_snapshot_links() we strip leading "v" and "V", while we currently only prepend a lower case "v" when parsing a snapshot file name. This results in broken snapshot links for tags that start with an upper case "V". Avoid this by prepending a "V" as a fallback. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de>
2013-04-08use struct strbuf instead of static buffersJohn Keeping1-17/+43
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.

2013-04-08Convert cgit_print_error to a variadic functionJohn Keeping1-6/+10
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>
2013-04-08Always #include corresponding .h in .c filesJohn Keeping1-0/+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>

2013-03-04ui-snapshot.c: Fill argv[0] with dummy.Jason A. Donenfeld1-0/+1
parse_archive_args does not pass PARSE_OPT_KEEP_ARGV0 to parse_args, which means the first argument will be discarded, as though it were a function being called from the command-line. Thus, we fill argv[0] with a dummy argument to prevent this from happening. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2012-09-27ui-snapshot: pass -n to gzip, to suppress timestampJason A. Donenfeld1-8/+10
Since cgit snapshots of tags are often used for releases, we don't want the rarely used feature of the gzip compressor that includes an embedded timestamp into the archive, since this makes each tarball of the same (potentially signed) tag different. This commit refactors the archive handling code a bit so that each different format is able to run with an arbitrary argv for the filter.
2011-06-13cgit.c: always setup cgit repo environment variablesLars Hjemli1-1/+1

2008-10-11ui-snapshot: add dwimmeryLars Hjemli1-13/+81
When downloading a snapshot, the snapshot name will often contain the repo name combined with a tag. This patch tries to exploit this so that the correct revision is downloaded even if no specific revision is specified. PS: this only occurs if neither 'h' nor 'id' is specified in the query- string. PPS: this also fixes a bug which occurs when trying to download a filename with an unsupported suffix: it used to try to print an error message to the user but failed since it didn't prepare the output properly.
