2007-03-07General const correctness fixesLibravatar Shawn O. Pearce1-12/+9
We shouldn't attempt to assign constant strings into char*, as the string is not writable at runtime. Likewise we should always be treating unsigned values as unsigned values, not as signed values. Most of these are very straightforward. The only exception is the (unnecessary) xstrdup/free in builtin-branch.c for the detached head case. Since this is a user-level interactive type program and that particular code path is executed no more than once, I feel that the extra xstrdup call is well worth the easy elimination of this warning.

2007-02-27convert object type handling from a string to a numberLibravatar Nicolas Pitre1-3/+3
We currently have two parallel notation for dealing with object types in the code: a string and a numerical value. One of them is obviously redundent, and the most used one requires more stack space and a bunch of strcmp() all over the place. This is an initial step for the removal of the version using a char array found in object reading code paths. The patch is unfortunately large but there is no sane way to split it in smaller parts without breaking the system.

2006-12-30i18n: drop "encoding" header in the output after re-coding.Libravatar Junio C Hamano1-0/+45
After re-coding the commit message into the encoding the user specified (either with core.logoutputencidng or --encoding option), this drops the "encoding" header altogether. The output is after re-coding as the user asked (either with the config or --encoding=<encoding> option), and the extra header becomes redundant information.

2006-12-30commit re-encoding: fix confusion between no and default conversion.Libravatar Junio C Hamano1-0/+2
Telling the git-log family not to do any character conversion is done with --encoding=none, which sets log_output_encoding to an empty string. However, logmsg_reencode() confused this with log_output_encoding and commit_encoding set to NULL. The latter means we should use the default encoding (i.e. utf-8).

2006-12-27UTF-8: introduce i18n.logoutputencoding.Libravatar Junio C Hamano1-12/+15
It is plausible for somebody to want to view the commit log in a different encoding from i18n.commitencoding -- the project's policy may be UTF-8 and the user may be using a commit message hook to run iconv to conform to that policy (and either not have i18n.commitencoding to default to UTF-8 or have it explicitly set to UTF-8). Even then, Latin-1 may be more convenient for the usual pager and the terminal the user uses. The new variable i18n.logoutputencoding is used in preference to i18n.commitencoding to decide what encoding to recode the log output in when git-log and friends formats the commit log message.

2006-12-26Teach log family --encodingLibravatar Junio C Hamano1-3/+58
Updated commit objects record the encoding used in their encoding header. This updates the log family to reencode it into the encoding specified in i18n.commitencoding (or the default, which is "utf-8") upon output. To force a specific encoding that is different, log family takes command line flag --encoding=<encoding>; giving --encoding=none entirely disables the reencoding and lets you view log messges in their original encoding.

2006-12-17rev-list --left-rightLibravatar Junio C Hamano1-5/+5
The output from "symmetric diff", i.e. A...B, does not distinguish between commits that are reachable from A and the ones that are reachable from B. In this picture, such a symmetric diff includes commits marked with a and b. x---b---b branch B / \ / / . / / \ o---x---a---a branch A However, you cannot tell which ones are 'a' and which ones are 'b' from the output. Sometimes this is frustrating. This adds an output option, --left-right, to rev-list. rev-list --left-right A...B would show ones reachable from A prefixed with '<' and the ones reachable from B prefixed with '>'. When combined with --boundary, boundary commits (the ones marked with 'x' in the above picture) are shown with prefix '-', so you would see list that looks like this: git rev-list --left-right --boundary --pretty=oneline A...B >bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 3rd on b >bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb 2nd on b <aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 3rd on a <aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 2nd on a -xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 1st on b -xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 1st on a Signed-off-by: Junio C Hamano <junkio@cox.net>

2006-11-24support fetching into a shallow repositoryLibravatar Johannes Schindelin1-0/+21
A shallow commit is a commit which has parents, which in turn are "grafted away", i.e. the commit appears as if it were a root. Since these shallow commits should not be edited by the user, but only by core git, they are recorded in the file $GIT_DIR/shallow. A repository containing shallow commits is called shallow. The advantage of a shallow repository is that even if the upstream contains lots of history, your local (shallow) repository needs not occupy much disk space. The disadvantage is that you might miss a merge base when pulling some remote branch. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <junkio@cox.net>
2006-10-11commit: fix a segfault when displaying a commit with unreachable parentsLibravatar Eric Wong1-4/+7
I was running git show on various commits found by fsck-objects when I found this bug. Since find_unique_abbrev() cannot find an abbreviation for an object not in the database, it will return NULL, which is bad to run strlen() on. So instead, we'll just display the unabbreviated sha1 that we referenced in the commit. I'm not sure that this is the best 'fix' for it because the commit I was trying to show was broken, but I don't think a program should segfault even if the user tries to do something stupid.

2006-08-26Relative timestamps in git logLibravatar Linus Torvalds1-2/+2
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 updates the type-enumeration constants introduced to reduce the memory footprint of "struct object" to match the type bits already used in the packfile format, by removing the former (i.e. TYPE_* constant macros) and using the latter (i.e. enum object_type) throughout the code for consistency.

2006-06-19Add specialized object allocatorLibravatar Linus Torvalds1-1/+1
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>
2006-06-17Move "void *util" from "struct object" into "struct commit"Libravatar Linus Torvalds1-2/+2
Every single user actually wanted this only for commit objects, and we have no reason to waste space on it for other object types. So just move the structure member from the low-level "struct object" into the "struct commit". This leaves the commit object the same size, and removes one unnecessary pointer from all other object allocations. This shrinks memory usage (still at a fairly hefty half-gig, admittedly) of "git-rev-list --all --objects" on the mozilla repo by another 5% in my tests.

2006-06-17Shrink "struct object" a bitLibravatar Linus Torvalds1-4/+4
This shrinks "struct object" by a small amount, by getting rid of the "struct type *" pointer and replacing it with a 3-bit bitfield instead. In addition, we merge the bitfields and the "flags" field, which incidentally should also remove a useless 4-byte padding from the object when in 64-bit mode. Now, our "struct object" is still too damn large, but it's now less obviously bloated, and of the remaining fields, only the "util" (which is not used by most things) is clearly something that should be eventually discarded. This shrinks the "git-rev-list --all" memory use by about 2.5% on the kernel archive (and, perhaps more importantly, on the larger mozilla archive). That may not sound like much, but I suspect it's more on a 64-bit platform. There are other remaining inefficiencies (the parent lists, for example, probably have horrible malloc overhead), but this was pretty obvious. Most of the patch is just changing the comparison of the "type" pointer from one of the constant string pointers to the appropriate new TYPE_xxx small integer constant.
