	4d5ee956	2022-07-02T21:27:21		create and verify tags signed by SSH keys This adds a new -s flag to 'got tag' that specifies the signer identity (for example, a key file) of the tagger. The tag object will include a signature that validates each of the tag object headers and the tag message. Verifying these signed tags requires maintaining an allowed signers file which maps signer identities (i.e. the email address of the tagger) to SSH public keys. See ssh-keygen(1) for more details of the allowed signers file. After creating this file and providing the path to it in got.conf(5) using the allowed_signers option, tags may be verified using with 'got tag -V tag_name'. The return code will be non-zero if a signature fails to verify. ok stsp@
	61af9b21	2022-06-28T11:31:11		implement support for commit coloring in got-read-pack for speed ok op, tracey
	d8b5af43	2022-06-19T11:51:33		use the commitid in the patch diff3 conflict header suggested by and ok stsp@
	55e9459f	2022-06-19T11:51:32		got patch: use diff3 to merge the changes Parse the "blob -" metadata in diffs produced by 'got diff' and use the original file for patching. Then, use the diff3 with the current version of the file to merge the differences. This solves many failures automagically or at least turns them into a conflict. ok/improvements stsp@
	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@
	35095610	2022-06-14T10:35:07		got patch: use ints for line offsets instead of longs ints have the advantage that their size is more likely to be the same across the various architecture supported by OpenBSD, thus introducing less possible differences. INT_MAX is still (at least) a few order of magnitudes higher than the patches we dealt with (even abnormal ones.) suggested by stsp@
	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@
	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@
	cee6a7ea	2022-06-07T15:56:46		implement object enumeration support in got-read-pack ok op@
	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@
	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@
	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@
	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@
	9d6cabd5	2022-04-07T09:28:59		got patch: allow to strip path components Move some bits from the libexec helper to the main process so we know if the patch was generated by git or not and finally document the automatic stripping of a/ and b/ prefixes added by git-diff(1). ok stsp@

	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@
