Stefan Sperling 61af9b21 2022-06-28T11:31:11 implement support for commit coloring in got-read-pack for speed ok op, tracey
Omar Polo 336075a4 2022-06-25T09:22:02 build with -Wmissing-prototypes ok stsp@
Stefan Sperling 80f51a9e 2022-06-18T16:32:12 fix unexpected imsg error after incomplete enumeration in got-read-pack reported by jrick and op@ ok op@
Omar Polo 031611fc 2022-06-18T16:17:45 memset all stack-allocated structs used to send messages; ok stsp@
Omar Polo 1a69d37f 2022-06-18T16:17:45 zero the whole struct got_imsg_object before sending it otherwise some fields may be unitialized and fail the validation done on the receiving side. ok stsp@
Stefan Sperling afd31498 2022-06-14T22:35:34 fix a harmless off-by-one from previous commit
Stefan Sperling a5e587e0 2022-06-14T22:32:11 fix a bug in got_privsep_send_object_idlist() exposed by recent changes The old code did not work correctly if only a single object Id was to be sent to got-read-pack. Make got-read-pack error out if the list of commits for object enumeration is empty to catch this problem if it occurs again. Found by the send_basic test, which was failing with GOT_TEST_PACK=1 ok tracey
Stefan Sperling db9b9b1c 2022-06-14T20:26:15 let got-read-pack be explicit about whether it could enumerate all objects This allows the main process to avoid looping over all object IDs again in case the pack file used for enumeration is complete. ok op@
Omar Polo b4b1b9c0 2022-06-14T13:16:15 remove trailing whitespaces
Omar Polo 0fca100c 2022-06-14T13:16:15 compute object size, not pointer size in this case they're luckily the same; got_imsg_object_idlist and got_imsg_reused_delta only have one size_t long field. ok stsp@
Omar Polo c98b0f0b 2022-06-14T13:16:15 strictier validation for data received from libexec helpers use correct error code and ok stsp@
Omar Polo 3e6054c4 2022-06-14T13:16:14 drop unused variable
Omar Polo bf31a716 2022-06-14T13:16:14 use strndup instead of malloc+memcpy Simplifies the reading of the author/committer string and makes also the code shorter. ok stsp@
Omar Polo 71fee5a3 2022-06-14T13:16:14 don't check datalen when calling recv_imsg_error recv_imsg_error already checks the size of the message, and it does so more precisely than the removed code. ok stsp@
Stefan Sperling 0ab4c957 2022-06-13T17:13:59 Bring back object enumeration inside got-read-pack as a fast path. The problem that was found in the earlier version has been fixed. ok op@
Stefan Sperling e44d9391 2022-06-07T19:20:01 revert object enumeration in got-read-pack for now; needs more work This implementation marked commits and trees as enumerated before all trees which they depend on were enumerated. This behaviour leads to incomplete pack files when a tree is only partially packed and got-read-pack hits a missing tree entry as a result. The algorithm must be reworked such that packed leave nodes are marked enumerated first, then bubble-up. Found by op@
Stefan Sperling f0972833 2022-06-07T16:00:56 fix wrong line wrap; pointed out by op@
Stefan Sperling 876f8c1a 2022-06-07T15:59:48 imsg_add() already frees wbuf on error; pointed out by op@
Stefan Sperling cee6a7ea 2022-06-07T15:56:46 implement object enumeration support in got-read-pack ok op@
Stefan Sperling c9b75c7b 2022-05-19T07:31:57 revert "Skip poll(2) if an imsgbuf has a non-empty read buffer" imsg_read() will call recvmsg() on the file descriptor regardless of the read buffer's state, so we should ensure that data is ready. The read buffer is used by imsg_get(), not imsg_read(). We already call imsg_get() before imsg_read(), and call the latter only if imsg_get() returns zero.
Stefan Sperling 2ab71455 2022-05-19T07:18:46 Skip poll(2) if an imsgbuf has a non-empty read buffer.
Stefan Sperling 1453347d 2022-05-19T07:14:21 imsg_add() frees its msg argument on error; avoid double-free in error paths
Stefan Sperling 33fd69c2 2022-05-19T06:50:59 batch up tree entries in imsg instead of sending one imsg per tree entry This speeds up loading of trees significantly. ok op@
Stefan Sperling 9985f404 2022-05-19T06:40:09 parse tree entries into an array instead of a pathlist Avoids some extra malloc/free in a performance-critical path. ok op@
Stefan Sperling 3483a4da 2022-05-18T07:45:08 prevent an out-of-bounds access in got_privsep_recv_tree()
Stefan Sperling baef4d75 2022-05-18T07:44:49 plug memory leak in an error path of got_privsep_recv_tree()
Stefan Sperling 13fcf1bf 2022-05-18T07:44:30 make got_privsep_recv_tree() reject trees with less than zero entries
Stefan Sperling 7429ae85 2022-05-18T07:43:45 rework logic in got_privsep_recv_tree() to avoid an ugly 'goto' no functional change
Stefan Sperling fae7e038 2022-05-07T11:50:56 run the search for deltas to reuse in got-read-pack This significantly speeds up the deltification step of packing by avoiding imsg traffic. gotadmin no longer requests individual raw deltas from got-read-pack to check whether it can reuse them. Instead, got-read-pack obtains a list of objects we want to pack, and hands back the list of all deltas in its pack file which can be reused. Messages are now batched such that imsg buffers are filled as much as possible. Another advantage is that deltas we are not going to reuse will no longer be written to the delta cache file, saving disk space. Before this patch, any raw delta candidate was written to the delta cache file by got-read-pack, and the decision whether to reuse the delta happened afterwards in the gotadmin process. Code for reading individual raw deltas is now unused and could be removed at some point. ok op@
Stefan Sperling 2d9e6abf 2022-05-04T13:43:24 store deltas in compressed form while packing, both in memory and cache file This reduces memory and disk space consumption during packing. with tweaks + memleak on error fix from op@ ok op@
Stefan Sperling d7b5a0e8 2022-04-20T14:00:12 inline struct got_object_id in struct got_object_qid Saves us from doing a malloc/free call for every item on the list. ok op@
Omar Polo e9ce266e 2022-03-07T22:26:08 add `got patch' command for applying unified diffs
Omar Polo 8934ea8b 2022-02-14T13:14:36 factorize imsg_clear calls after imsg_flush failures imsg_clear frees and closes resources allocated as part of enqueueing imsgs so it's a no-op after reads. discussed with and ok stsp@

Stefan Sperling 4a55b231 2021-12-09T16:10:25 ignore the return value of closefrom(2); patch by Anna a.k.a. CyberTailor millert@ suggests that this check is not needed, and that ideally we should be using close-on-exec instead. I will look into this, but in the meantime this change will help -portable: https://bugs.gentoo.org/828003

Stefan Sperling c3564dfa 2021-07-15T07:48:40 don't scan pack index offsets for large values if pack file is < 2GB This saves an iteration over the entire h->offsets array when opening a pack index which should not contain large offsets in the first place. ok millert@

Christian Weisgerber dbdddfee 2021-06-23T20:48:35 switch from SIMPLEQ to equivalent STAILQ macros The singly-linked tail queue macros were added to OpenBSD 6.9 and are more widely available on other systems. ok stsp
Stefan Sperling a8591711 2021-06-18T13:52:26 raw object size should not include the length of the object's header This way, the size of a raw object is the same regardless of whether the object was found in a loose object file or in a pack file.

Stefan Sperling 0c8b29c5 2021-01-05T17:22:14 add a 'fetch-all-branches' configuration setting to got.conf(5) Set fetch-all-branches in the got.conf(5) file created by 'got clone -a' in order to make a future 'got fetch' act like 'got fetch -a' by default.
