2009-01-17builtin-fsck: fix off by one head countLibravatar Christian Couder1-1/+1
According to the man page, if "git fsck" is passed one or more heads, it should verify connectivity and validity of only objects reachable from the heads it is passed. However, since 5ac0a20 (Make builtin-fsck.c use parse_options., 2007-10-15) the command behaved as if no heads were passed, when given only one argument.

* maint: fsck: reduce stack footprint make sure packs to be replaced are closed beforehand
2008-12-11fsck: reduce stack footprintLibravatar Linus Torvalds1-7/+31
The logic to mark all objects that are reachable from tips of refs were implemented as a set of recursive functions. In a repository with a deep enough history, this can easily eat up all the available stack space. Restructure the code to require less stackspace by using an object array to keep track of the objects that still need to be processed.

2008-08-05Teach fsck and prune that tmp_obj_ file names may not be 14 bytes longLibravatar Brandon Casey1-1/+1
As Shawn pointed out, not all temporary file creation routines can ensure that the generated temporary file is of a certain length. e.g. Java's createTempFile(prefix, suffix). So just depend on the prefix 'tmp_obj_' for detection. Update prune, and fix the "fix" introduced by a08c53a1 :) Signed-off-by: Brandon "appendixless" Casey <casey@nrlssc.navy.mil> Acked-by: Shawn O.

2008-07-27fsck: Don't require tmp_obj_ file names are 14 bytes in lengthLibravatar Shawn O. Pearce1-4/+2
Not all temporary file creation routines will ensure 14 bytes are used to generate the temporary file name. In C Git this may be true, but alternate implementations such as jgit are not always able to generate a temporary file name with a specific prefix and also ensure the file name length is 14 bytes long. Since temporary files in a directory we are fsck'ing should be uncommon (as they are short lived only long enough for an active writer to finish writing the file and rename it) we shouldn't see these show up very often. Always using a prefixcmp() call and ignoring the length opens up room for other implementations to use different name generation schemes. Signed-off-by: Shawn O.

2008-07-24Teach fsck and prune about the new location of temporary objectsLibravatar Brandon Casey1-0/+4

2008-07-13Make usage strings dash-lessLibravatar Stephan Beyer1-1/+1
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.

2008-06-24move show_pack_info() where it belongsLibravatar Nicolas Pitre1-1/+1
This is called when verify_pack() has its verbose argument set, and verbose in this context makes sense only for the actual 'git verify-pack' command. Therefore let's move show_pack_info() to builtin-verify-pack.c instead and remove useless verbose argument from verify_pack().

2008-02-25builtin-fsck: reports missing parent commitsLibravatar Martin Koegler1-0/+24
parse_commit ignores parent commits with certain errors (eg. a non commit object is already loaded under the sha1 of the parent). To make fsck reports such errors, it has to compare the nummer of parent commits returned by parse commit with the number of parent commits in the object or in the graft/shallow file.

2008-02-03git-fsck: report missing author/commit line in a commit as an errorLibravatar Martin Koegler1-3/+3
A zero commit date could be caused by: * a missing author line * a missing commiter line * a malformed email address in the commiter line * a malformed commit date Simply reporting it as zero commit date is missleading.

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>

In this particular location of fsck the index should have already been opened by verify_pack, which is called just before we get here and loop through the object names. However, just in case a future version of that function does not use the index file we'll double-check its open before we access the num_objects field. Better safe now than sorry later.

Released versions of fast-import have been able to create a tree that contains files or subtrees that contain no name.

Detached HEAD is just a normal state of a repository. Do not say anything about it.

Since the subprojects don't necessarily even exist in the current tree, much less in the current git repository (they are totally independent repositories), we do not want to try to follow the chain from one git repository to another through a gitlink.

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.

2007-04-05Fix lost-found to show commits only referenced by reflogsLibravatar Shawn O. Pearce1-1/+7
Prior to 1.5.0 the git-lost-found utility was useful to locate commits that were not referenced by any ref. These were often amends, or resets, or tips of branches that had been deleted. Being able to locate a 'lost' commit and recover it by creating a new branch was a useful feature in those days. Unfortunately 1.5.0 added the reflogs to the reachability analysis performed by git-fsck, which means that most commits users would consider to be lost are still reachable through a reflog. So most (or all!) commits are reachable, and nothing gets output from git-lost-found. Now git-fsck can be told to ignore reflogs during its reachability analysis, making git-lost-found useful again to locate commits that are no longer referenced by a ref itself, but may still be referenced by a reflog.

Let's avoid the open coded pack index reference in pack-object and use nth_packed_object_sha1() instead. This will help encapsulating index format differences in one place.

git-fsck always exited with status 0, which was a bit sloppy. This makes it exit with a non-zero status when errors are found. The error code is an OR'ed result of: 1 if corrupted objects are found. 2 if objects that are ought to be reachable are missing or corrupt. For example, it would exit with 1 in a repository with an unreachable corrupt object. If a tree object of the HEAD commit is corrupt, you would get 3. Signed-off-by: Junio C Hamano <junkio@cox.net>
