2009-11-10Let 'git <command> -h' show usage without a git dirJonathan Nieder
There is no need for "git <command> -h" to depend on being inside a repository. Reported by Gerfried Fuchs through http://bugs.debian.org/462557 Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-09-01Style fixes, add a space after if/for/while.Brian Gianforcaro
The majority of code in core git appears to use a single space after if/for/while. This is an attempt to bring more code to this standard. These are entirely cosmetic changes. Signed-off-by: Brian Gianforcaro <b.gianfo@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2009-01-26Add calls to git_extract_argv0_path() in programs that call git_config_*Steffen Prohaska
Programs that use git_config need to find the global configuration. When runtime prefix computation is enabled, this requires that git_extract_argv0_path() is called early in the program's main(). This commit adds the necessary calls. Signed-off-by: Steffen Prohaska <prohaska@zib.de> Acked-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

LF at the end of format strings given to die() is redundant because die already adds one on its own. Signed-off-by: Alexander Potashev <aspotashev@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2008-07-13Make usage strings dash-lessStephan Beyer
When you misuse a git command, you are shown the usage string. But this is currently shown in the dashed form. So if you just copy what you see, it will not work, when the dashed form is no longer supported. This patch makes git commands show the dash-less version. For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh generates a dash-less usage string now.

2007-06-07War on whitespaceJunio C Hamano
This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time. There are a few files that need to have trailing whitespaces (most notably, test vectors). The results still passes the test, and build result in Documentation/ area is unchanged.

2007-05-30Simplify index access condition in count-objects, pack-redundantShawn O. Pearce
My earlier lazy index opening patch changed this condition to check index_data and call open_pack_index if it was NULL. In truth we only care about num_objects. Since open_pack_index does no harm if the index is already open, and all indexes are likely to be closed in this application, the "performance optimization" of inlining the index_data check here was wrong.

2007-05-27Lazily open pack index files on demandShawn O. Pearce
In some repository configurations the user may have many packfiles, but all of the recent commits/trees/tags/blobs are likely to be in the most recent packfile (the one with the newest mtime). It is therefore common to be able to complete an entire operation by accessing only one packfile, even if there are 25 packfiles available to the repository. Rather than opening and mmaping the corresponding .idx file for every pack found, we now only open and map the .idx when we suspect there might be an object of interest in there. Of course we cannot known in advance which packfile contains an object, so we still need to scan the entire packed_git list to locate anything. But odds are users want to access objects in the most recently created packfiles first, and that may be all they ever need for the current operation. Junio observed in b867092f that placing recent packfiles before older ones can slightly improve access times for recent objects, without degrading it for historical object access. This change improves upon Junio's observations by trying even harder to avoid the .idx files that we won't need. Signed-off-by: Shawn O.

2007-04-10pack-redundant.c: learn about index v2Nicolas Pitre
Initially the conversion was made using nth_packed_object_sha1() which made this file completely index version agnostic. Unfortunately the overhead was quite significant so I went back to raw index walking but with selectable base and step values which brought back similar performances as the original.

2007-03-17[PATCH] clean up pack index handling a bitNicolas Pitre
Especially with the new index format to come, it is more appropriate to encapsulate more into check_packed_git_idx() and assume less of the index format in struct packed_git. To that effect, the index_base is renamed to index_data with void * type so it is not used directly but other pointers initialized with it. This allows for a couple pointer cast removal, as well as providing a better generic name to grep for when adding support for new index versions or formats. And index_data is declared const too while at it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-07Use off_t when we really mean a file offset.Shawn O. Pearce
Not all platforms have declared 'unsigned long' to be a 64 bit value, but we want to support a 64 bit packfile (or close enough anyway) in the near future as some projects are getting large enough that their packed size exceeds 4 GiB. By using off_t, the POSIX type that is declared to mean an offset within a file, we support whatever maximum file size the underlying operating system will handle. For most modern systems this is up around 2^60 or higher. Signed-off-by: Shawn O. Pearce <spearce@spearce.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

Binary representation of object names are unsigned char[20], not signed. Also verbose output had %lu format printing size_t without (unsigned long) cast other places already had, so match that. Using format %zu was suggested but might not be supported as widely. Noted by Morten Welinder, fixed with input from H. Peter Anvin and Hideaki Yoshifuji.

This lets us do "git-fsck-objects --full --unreachable | cut -d ' ' -f3 | git-pack-redundant --all", which will keep git-pack-redundant from keeping packs just because they contain unreachable objects.
