2008-03-15Merge branch 'maint'Libravatar Junio C Hamano1-13/+15
* maint: Make man page building quiet when DOCBOOK_XSL_172 is defined git-new-workdir: Share SVN meta data between work dirs and the repository rev-parse: fix meaning of rev~ vs rev~0. git-svn: don't blindly append '*' to branch/tags config
2008-03-14rev-parse: fix meaning of rev~ vs rev~0.Libravatar Linus Torvalds1-13/+15
I think it would make more sense for rev~ to have the same guarantees that rev^ has, namely to always return a commit. I would also suggest that not giving a number would have the same effect of defaulting to 1, not 0. Right now it's a bit illogical, but at least it's an _undocumented_ illogical behaviour. This patch makes '^' and '~' act the same for the default count (i.e. both default to 1), and also have the same behaviour for a count of zero. Before (no discernible pattern): [torvalds@woody git]$ git rev-parse v1.5.1 v1.5.1^0 v1.5.1~0 v1.5.1^ v1.5.1~ 45354a57ee7e3e42c7137db6c94fa968c6babe8d 89815cab95268e8f0f58142b848ac4cd5e9cbdcb 45354a57ee7e3e42c7137db6c94fa968c6babe8d 045f5759c97746589a067461e50fad16f60711ac 45354a57ee7e3e42c7137db6c94fa968c6babe8d After (fairly logical): [torvalds@woody git]$ git rev-parse v1.5.1 v1.5.1^0 v1.5.1~0 v1.5.1^ v1.5.1~ 45354a57ee7e3e42c7137db6c94fa968c6babe8d 89815cab95268e8f0f58142b848ac4cd5e9cbdcb 89815cab95268e8f0f58142b848ac4cd5e9cbdcb 045f5759c97746589a067461e50fad16f60711ac 045f5759c97746589a067461e50fad16f60711ac Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2008-03-01find_unique_abbrev(): redefine semanticsLibravatar Junio C Hamano1-7/+6
The function returned NULL when no object that matches the name was found, but that made the callers more complicated, as nobody used that NULL return as an indication that no object with such a name exists. They (at least the careful ones) instead took the full 40-hexdigit and used in such a case, and the careless ones segfaulted. With this "git rev-parse --short 5555555555555555555555555555555555555555" would stop segfaulting. This is based on Jeff King's rewrite to my RFC patch, but "missing" logic swapped to "exists". The final logic reads: For existing objects, make sure the abbreviated string uniquely identifies it. Otherwise, make sure the abbreviated string is long enough so that it would not name any existing object. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-02-22Avoid unnecessary "if-before-free" tests.Libravatar Jim Meyering1-4/+2
This change removes all obvious useless if-before-free tests. E.g., it replaces code like this: if (some_expression) free (some_expression); with the now-equivalent: free (some_expression); It is equivalent not just because POSIX has required free(NULL) to work for a long time, but simply because it has worked for so long that no reasonable porting target fails the test. Here's some evidence from nearly 1.5 years ago: http://www.winehq.org/pipermail/wine-patches/2006-October/031544.html FYI, the change below was prepared by running the following: git ls-files -z | xargs -0 \ perl -0x3b -pi -e \ 's/\bif\s*\(\s*(\S+?)(?:\s*!=\s*NULL)?\s*\)\s+(free\s*\(\s*\1\s*\))/$2/s' Note however, that it doesn't handle brace-enclosed blocks like "if (x) { free (x); }". But that's ok, since there were none like that in git sources. Beware: if you do use the above snippet, note that it can produce syntactically invalid C code. That happens when the affected "if"-statement has a matching "else". E.g., it would transform this if (x) free (x); else foo (); into this: free (x); else foo (); There were none of those here, either. If you're interested in automating detection of the useless tests, you might like the useless-if-before-free script in gnulib: [it *does* detect brace-enclosed free statements, and has a --name=S option to make it detect free-like functions with different names] http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=build-aux/useless-if-before-free Addendum: Remove one more (in imap-send.c), spotted by Jean-Luc Herren <jlh@gmx.ch>.

2008-01-21Make on-disk index representation separate from in-core oneLibravatar Linus Torvalds1-1/+1
This converts the index explicitly on read and write to its on-disk format, allowing the in-core format to contain more flags, and be simpler. In particular, the in-core format is now host-endian (as opposed to the on-disk one that is network endian in order to be able to be shared across machines) and as a result we can dispense with all the htonl/ntohl on accesses to the cache_entry fields. This will make it easier to make use of various temporary flags that do not exist in the on-disk format. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-11-18add refname_match()Libravatar Steffen Prohaska1-12/+2
We use at least two rulesets for matching abbreviated refnames with full refnames (starting with 'refs/'). git-rev-parse and git-fetch use slightly different rules. This commit introduces a new function refname_match (const char *abbrev_name, const char *full_name, const char **rules). abbrev_name is expanded using the rules and matched against full_name. If a match is found the function returns true. rules is a NULL-terminate list of format patterns with "%.*s", for example: const char *ref_rev_parse_rules[] = { "%.*s", "refs/%.*s", "refs/tags/%.*s", "refs/heads/%.*s", "refs/remotes/%.*s", "refs/remotes/%.*s/HEAD", NULL }; Asterisks are included in the format strings because this is the form required in sha1_name.c. Sharing the list with the functions there is a good idea to avoid duplicating the rules. Hopefully this facilitates unified matching rules in the future. This commit makes the rules used by rev-parse for resolving refs to sha1s available for string comparison. Before this change, the rules were buried in get_sha1*() and dwim_ref(). A follow-up commit will refactor the rules used by fetch. refname_match() will be used for matching refspecs in git-send-pack. Thanks to Daniel Barkalow <barkalow@iabervon.org> for pointing out that ref_matches_abbrev in remote.c solves a similar problem and care should be taken to avoid confusion.

2007-05-26Attempt to delay prepare_alt_odb during get_sha1Libravatar Shawn O. Pearce1-1/+1
Not every input value passed to get_sha1 is an abbreviated SHA-1. Its actually quite common for refs to be passed and for those refs to resolve to full SHA-1s, in which case we may not need to initialize the alternate object database list in this process. I'm relocating the call to prepare_alt_odb closer to the code that actually needs it to maintain the fix first introduced by Junio in 99a19b43 (to avoid ambiguous SHA-1 abbreviations from being accepted). This allows us to avoid the alt_odb list setup if we won't actually need it. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

The coming index format change doesn't allow for the number of objects to be determined from the size of the index file directly. Instead, Let's initialize a field in the packed_git structure with the object count when the index is validated since the count is always known at that point. While at it let's reorder some struct packed_git fields to avoid padding due to needed 64-bit alignment for some of them.

As we permit up to 2^32-1 objects in a single packfile we cannot use a signed int to represent the object offset within a packfile, after 2^31-1 objects we will start seeing negative indexes and error out or compute bad addresses within the mmap'd index.

2006-06-17Shrink "struct object" a bitLibravatar Linus Torvalds1-11/+11
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.
