2006-11-03improve fetch-pack's handling of kept packsLibravatar Nicolas Pitre1-4/+0
Since functions in fetch-clone.c were only used from fetch-pack.c, its content has been merged with fetch-pack.c. This allows for better coupling of features with much simpler implementations. One new thing is that the (abscence of) --thin also enforce it on index-pack now, such that index-pack will abort if a thin pack was _not_ asked for. The -k or --keep, when provided twice, now causes the fetched pack to be left as a kept pack just like receive-pack currently does. Eventually this will be used to close a race against concurrent repacking. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-11-03Teach receive-pack how to keep pack files based on object count.Libravatar Shawn Pearce1-0/+1
Since keeping a pushed pack or exploding it into loose objects should be a local repository decision this teaches receive-pack to decide if it should call unpack-objects or index-pack --stdin --fix-thin based on the setting of receive.unpackLimit and the number of objects contained in the received pack. If the number of objects (hdr_entries) in the received pack is below the value of receive.unpackLimit (which is 5000 by default) then we unpack-objects as we have in the past. If the hdr_entries >= receive.unpackLimit then we call index-pack and ask it to include our pid and hostname in the .keep file to make it easier to identify why a given pack has been kept in the repository. Currently this leaves every received pack as a kept pack. We really don't want that as received packs will tend to be small. Instead we want to delete the .keep file automatically after all refs have been updated. That is being left as room for future improvement. Signed-off-by: Shawn O.

2006-09-27update-ref: -d flag and ref creation safety.Libravatar Junio C Hamano1-0/+1
This adds -d flag to update-ref to allow safe deletion of ref. Before deleting it, the command checks if the given <oldvalue> still matches the value the caller thought the ref contained. Similarly, it also accepts 0{40} or an empty string as <oldvalue> to allow safe creation of a new ref. Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-27introduce delta objects with offset to baseLibravatar Nicolas Pitre1-2/+3
This adds a new object, namely OBJ_OFS_DELTA, renames OBJ_DELTA to OBJ_REF_DELTA to better make the distinction between those two delta objects, and adds support for the handling of those new delta objects in sha1_file.c only. The OBJ_OFS_DELTA contains a relative offset from the delta object's position in a pack instead of the 20-byte SHA1 reference to identify the base object. Since the base is likely to be not so far away, the relative offset is more likely to have a smaller encoding on average than an absolute offset. And for those delta objects the base must always be stored first because there is no way to know the distance of later objects when streaming a pack. Hence this relative offset is always meant to be negative. The offset encoding is slightly denser than the one used for object size -- credits to <linux@horizon.com> (whoever this is) for bringing it to my attention. This allows for pack size reduction between 3.2% (Linux-2.6) to over 5% (linux-historic). Runtime pack access should be faster too since delta replay does skip a search in the pack index for each delta in a chain.

2006-09-23many cleanups to sha1_file.cLibravatar Nicolas Pitre1-3/+3
Those cleanups are mainly to set the table for the support of deltas with base objects referenced by offsets instead of sha1. This means that many pack lookup functions are converted to take a pack/offset tuple instead of a sha1. This eliminates many struct pack_entry usages since this structure carried redundent information in many cases, and it increased stack footprint needlessly for a couple recursively called functions that used to declare a local copy of it for every recursion loop. In the process, packed_object_info_detail() has been reorganized as well so to look much saner and more amenable to deltas with offset support. Finally the appropriate adjustments have been made to functions that depend on the above changes. But there is no functionality changes yet simply some code refactoring at this point.

If receive.denyNonFastforwards is set to true, git-receive-pack will deny non fast-forwards, i.e. forced updates. Most notably, a push to a repository which has that flag set will fail. As a first user, 'git-init-db --shared' sets this flag, since in a shared setup, you are most unlikely to want forced pushes to succeed.

2006-09-17Make ref resolution sanerLibravatar Linus Torvalds1-2/+2
The old code used to totally mix up the notion of a ref-name and the path that that ref was associated with. That was not only horribly ugly (a number of users got the path, and then wanted to try to turn it back into a ref-name again), but it fundamnetally doesn't work at all once we do any setup where a ref doesn't have a 1:1 relationship with a particular pathname. This fixes things up so that we use the ref-name throughout, and only turn it into a pathname once we actually look it up in the filesystem. That makes a lot of things much clearer and more straightforward. Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-09-07pack-objects --unpacked=<existing pack> option.Libravatar Junio C Hamano1-1/+1
Incremental repack without -a essentially boils down to: rev-list --objects --unpacked --all | pack-objects $new_pack which picks up all loose objects that are still live and creates a new pack. This implements --unpacked=<existing pack> option to tell the revision walking machinery to pretend as if objects in such a pack are unpacked for the purpose of object listing. With this, we could say: rev-list --objects --unpacked=$active_pack --all | pack-objects $new_pack instead, to mean "all live loose objects but pretend as if objects that are in this pack are also unpacked". The newly created pack would be perfect for updating $active_pack by replacing it. Since pack-objects now knows how to do the rev-list's work itself internally, you can also write the above example by: pack-objects --unpacked=$active_pack --all $new_pack </dev/null Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-09-03more lightweight revalidation while reusing deflated stream in packingLibravatar Junio C Hamano1-0/+12
When copying from an existing pack and when copying from a loose object with new style header, the code makes sure that the piece we are going to copy out inflates well and inflate() consumes the data in full while doing so. The check to see if the xdelta really apply is quite expensive as you described, because you would need to have the image of the base object which can be represented as a delta against something else.

If GIT_TRACE is set to an absolute path (starting with a '/' character), we interpret this as a file path and we trace into it. Also if GIT_TRACE is set to an integer value greater than 1 and lower than 10, we interpret this as an open fd value and we trace into it. Note that this behavior is not compatible with the previous one. We also trace whole messages using one write(2) call to make sure messages from processes do net get mixed up in the middle.

2006-08-26Relative timestamps in git logLibravatar Linus Torvalds1-1/+1
I noticed that I was looking at the kernel gitweb output at some point rather than just do "git log", simply because I liked seeing the simplified date-format, ie the "5 days ago" rather than a full date. This adds infrastructure to do that for "git log" too. It does NOT add the actual flag to enable it, though, so right now this patch is a no-op, but it should now be easy to add a command line flag (and possibly a config file option) to just turn on the "relative" date format. The exact cut-off points when it switches from days to weeks etc are totally arbitrary, but are picked somewhat to avoid the "1 weeks ago" thing (by making it show "10 days ago" rather than "1 week", or "70 minutes ago" rather than "1 hour ago").

This abstracts away the size of the hash values when copying them from memory location to memory location, much as the introduction of hashcmp abstracted away hash value comparsion. A few call sites were using char* rather than unsigned char* so I added the cast rather than open hashcpy to be void*. This is a reasonable tradeoff as most call sites already use unsigned char* and the existing hashcmp is also declared to be unsigned char*.

2006-08-21Add write_or_die(), a helper functionLibravatar Rene Scharfe1-0/+1
The little helper write_or_die() won't come back with bad news about full disks or broken pipes. It either succeeds or terminates the program, making additional error handling unnecessary. This patch adds the new function and uses it to replace two similar ones (the one in tar-tree originally has been copied from cat-file btw.). I chose to add the fd parameter which both lacked to make write_or_die() just as flexible as write() and thus suitable for lib-ification. There is a regression: error messages emitted by this function don't show the program name, while the replaced two functions did. That's acceptable, I think; a lot of other functions do the same.

2006-08-12Better error message when we are unable to lock the index fileLibravatar Junio C Hamano1-1/+1
Most of the callers except the one in refs.c use the function to update the index file. Among the index writers, everybody except write-tree dies if they cannot open it for writing. This gives the function an extra argument, to tell it to die when it cannot create a new file as the lockfile. The only caller that does not have to die is write-tree, because updating the index for the cache-tree part is optional and not being able to do so does not affect the correctness. I think we do not have to be so careful and make the failure into die() the same way as other callers, but that would be a different patch. Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-07-13sha1_file: add the ability to parse objects in "pack file format"Libravatar Linus Torvalds1-0/+1
The pack-file format is slightly different from the traditional git object format, in that it has a much denser binary header encoding. The traditional format uses an ASCII string with type and length information, which is somewhat wasteful. A new object format starts with uncompressed binary header followed by compressed payload -- this will allow us later to copy the payload straight to packfiles. Obviously they cannot be read by older versions of git, so for now new object files are created with the traditional format. core.legacyheaders configuration item, when set to false makes the code write in new format for people to experiment with.

2006-07-13Status update on merge-recursive in CLibravatar Johannes Schindelin1-0/+4
This is just an update for people being interested. Alex and me were busy with that project for a few days now. While it has progressed nicely, there are quite a couple TODOs in merge-recursive.c, just search for "TODO". For impatient people: yes, it passes all the tests, and yes, according to the evil test Alex did, it is faster than the Python script. But no, it is not yet finished. Biggest points are: - there are still three external calls - in the end, it should not be necessary to write the index more than once (just before exiting) - a lot of things can be refactored to make the code easier and shorter BTW we cannot just plug in git-merge-tree yet, because git-merge-tree does not handle renames at all. This patch is meant for testing, and as such, - it compile the program to git-merge-recur - it adjusts the scripts and tests to use git-merge-recur instead of git-merge-recursive - it provides "TEST", a script to execute the tests regarding -recursive - it inlines the changes to read-cache.c (read_cache_from(), discard_cache() and refresh_cache_entry()) Brought to you by Alex Riesen and Dscho Signed-off-by: Junio C Hamano <junkio@cox.net>

This makes git-peek-remote able to basically do everything that git-ls-remote does (but obviously just for the native protocol, so no http[s]: or rsync: support). The default behaviour is the same, but you can now give a mixture of "--refs", "--tags" and "--heads" flags, where "--refs" forces git-peek-remote to only show real refs (ie none of the fakey tag lookups, but also not the special pseudo-refs like HEAD and MERGE_HEAD). The "--tags" and "--heads" flags respectively limit the output to just regular tags and heads, of course. You can still also ask to limit them by name too. You can combine the flags, so git peek-remote --refs --tags . will show all local _true_ tags, without the generated tag lookups (compare the output without the "--refs" flag). And "--tags --heads" will show both tags and heads, but will avoid (for example) any special refs outside of the standard locations. I'm also planning on adding a "--ignore-local" flag that allows us to ask it to ignore any refs that we already have in the local tree, but that's an independent thing.

2006-06-19Add specialized object allocatorLibravatar Linus Torvalds1-0/+11
This creates a simple specialized object allocator for basic objects. This avoids wasting space with malloc overhead (metadata and extra alignment), since the specialized allocator knows the alignment, and that objects, once allocated, are never freed. It also allows us to track some basic statistics about object allocations. For example, for the mozilla import, it shows object usage as follows: blobs: 627629 (14710 kB) trees: 1119035 (34969 kB) commits: 196423 (8440 kB) tags: 1336 (46 kB) and the simpler allocator shaves off about 2.5% off the memory footprint off a "git-rev-list --all --objects", and is a bit faster too. [ Side note: this concludes the series of "save memory in object storage". The thing is, there simply isn't much more to be saved on the objects. Doing "git-rev-list --all --objects" on the mozilla archive has a final total RSS of 131498 pages for me: that's about 513MB. Of that, the object overhead is now just 56MB, the rest is going somewhere else (put another way: the fact that this patch shaves off 2.5% of the total memory overhead, considering that objects are now not much more than 10% of the total shows how big the wasted space really was: this makes object allocations much more memory- and time-efficient). I haven't looked at where the rest is, but I suspect the bulk of it is just the pack-file loading. It may be that we should pack the tree objects separately from the blob objects: for git-rev-list --objects, we don't actually ever need to even look at the blobs, but since trees and blobs are interspersed in the pack-file, we end up not being dense in the tree accesses, so we end up looking at more pages than we strictly need to. So with a 535MB pack-file, it's entirely possible - even likely - that most of the remaining RSS is just the mmap of the pack-file itself. We don't need to map in _all_ of it, but we do end up mapping a fair amount. ] Signed-off-by: Linus Torvalds <torvalds@osdl.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
