2005-05-22Don't care about st_dev in the index fileLinus Torvalds
Thomas Glanzmann points out that it doesn't work well with different clients accessing the repository over NFS - they have different views on what the "device" for the filesystem is. Of course, other filesystems may not even have stable inode numbers. But we don't care. At least for now.
2005-05-22Some more sparse warning fixesLinus Torvalds
Proper function declarations and NULL pointer usage.
2005-05-22Fix up git-fsck-cache documentationLinus Torvalds
Notably, the "--unreachable" flag no longer depends on specified heads, and we should document what happens if no heads are given.
2005-05-22Include file cleanups..Linus Torvalds
Add <limits.h> to the include files handled by "cache.h", and remove extraneous #include directives from various .c files. The rule is that "cache.h" gets all the basic stuff, so that we'll have as few system dependencies as possible.

This allows you to just fetch stuff first, inspect it, and then resolve the merge separately if everything looks good.
2005-05-22[PATCH] Diffcore updates.Junio C Hamano
This moves the path selection logic from individual programs to a new diffcore transformer (diff-tree still needs to have its own for performance reasons). Also the header printing code in diff-tree was tweaked not to produce anything when pickaxe is in effect and there is nothing interesting to report. An interesting example is the following in the GIT archive itself: $ git-whatchanged -p -C -S'or something in a real script' Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-05-22[PATCH] Fix tweak in similarity estimator.Junio C Hamano
There was a screwy math bug in the estimator that confused what -C1 meant and what -C9 meant, only in one of the early "cheap" check, which resulted in quite confusing behaviour. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-22[PATCH] The diff-raw format updates.Junio C Hamano
Update the diff-raw format as Linus and I discussed, except that it does not use sequence of underscore '_' letters to express nonexistence. All '0' mode is used for that purpose instead. The new diff-raw format can express rename/copy, and the earlier restriction that -M and -C _must_ be used with the patch format output is no longer necessary. The patch makes -M and -C flags independent of -p flag, so you need to say git-whatchanged -M -p to get the diff/patch format. Updated are both documentations and tests.

2005-05-22[PATCH] Prepare diffcore interface for diff-tree header supression.Junio C Hamano

2005-05-21[PATCH] Tweak diffcore-rename heuristics.Junio C Hamano
The heuristics so far was to compare file size change and xdelta size against the average of file size before and after the change. This patch uses the smaller of pre- and post- change file size instead. It also makes a very small performance fix. I didn't measure it; I do not expect it to make any practical difference, but while scanning an already sorted list, breaking out in the middle is the right thing.

2005-05-21diff-tree: prettify output slightlyLinus Torvalds
Make the commit explanation buffer larger, and make sure that if we truncate it, we put a "..." marker there to visually tell people about the truncation (tested with a much smaller buffer to make sure it looks sane). Also make sure that the explanation is properly line-terminated, and add an extra newline iff we have a diff.

2005-05-21[PATCH] Diff overhaul, adding the other half of copy detection.Junio C Hamano
This patch extends diff-cache and diff-files to report the unmodified files to diff-core as well when -C (copy detection) is in effect, so that the unmodified files can also be used as the source candidates. The existing test t4003 has been extended to cover this case. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-21[PATCH] Introducing software archaeologist's tool "pickaxe".Junio C Hamano
This steals the "pickaxe" feature from JIT and make it available to the bare Plumbing layer. From the command line, the user gives a string he is intersted in. Using the diff-core infrastructure previously introduced, it filters the differences to limit the output only to the diffs between <src> and <dst> where the string appears only in one but not in the other. For example: $ ./git-rev-list HEAD | ./git-diff-tree -Sdiff-tree-helper --stdin -M would show the diffs that touch the string "diff-tree-helper". In real software-archaeologist application, you would typically look for a few to several lines of code and see where that code came from. The "pickaxe" module runs after "rename/copy detection" module, so it even crosses the file rename boundary, as the above example demonstrates.

2005-05-21[PATCH] Diff overhaul, adding half of copy detection.Junio C Hamano
This introduces the diff-core, the layer between the diff-tree family and the external diff interface engine. The calls to the interface diff-tree family uses (diff_change and diff_addremove) have not changed and will not change. The purpose of the diff-core layer is to provide an infrastructure to transform the set of differences sent from the applications, before sending them to the external diff interface. The recently introduced rename detection code has been rewritten to use the diff-core facility. When applications send in separate creates and deletes, matching ones are transformed into a single rename-and-edit diff, and sent out to the external diff interface as such. This patch also enhances the rename detection code further to be able to detect copies. Currently this happens only as long as copy sources appear as part of the modified files, but there already is enough provision for callers to report unmodified files to diff-core, so that they can be also used as copy source candidates. Extending the callers this way will be done in a separate patch. Please see and marvel at how well this works by trying out the newly added t/t4003-diff-rename-1.sh test script.

2005-05-20[PATCH] delta creationNicolas Pitre
This adds the ability to actually create delta objects using a new tool: git-mkdelta. It uses an ordered list of potential objects to deltafy against earlier objects in the list. A cap on the depth of delta references can be provided as well, otherwise the default is to not have any limit. A limit of 0 will also undeltafy any given object. Also provided is the beginning of a script to deltafy an entire repository. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-05-20[PATCH] delta checkNicolas Pitre

2005-05-20[PATCH] delta readNicolas Pitre
This makes the core code aware of delta objects and undeltafy them as needed. The convention is to use read_sha1_file() to have undeltafication done automatically (most users do that already so this is transparent). If the delta object itself has to be accessed then it must be done through map_sha1_file() and unpack_sha1_file(). In that context mktag.c has been switched to read_sha1_file() as there is no reason to do the full map+unpack manually.

2005-05-20sparse cleanupLinus Torvalds
Fix various things that sparse complains about: - use NULL instead of 0 - make sure we declare everything properly, or mark it static - use proper function declarations ("fn(void)" instead of "fn()") Sparse is always right.
2005-05-20[PATCH] Simplify "reverse-diff" logic in the diff core.Junio C Hamano
Instead of swapping the arguments just before output, this patch makes the swapping happen on the input side of the diff core, when "reverse-diff" is in effect. This greatly simplifies the logic, but more importantly it is necessary for upcoming "copy detection" work.

2005-05-20[PATCH] Diff-files fix with more tests.Junio C Hamano
The same check we added earlier to update-cache to catch ENOTDIR turns out to be missing from diff-files.

2005-05-20diff-tree: use new base_name_compare() helper functionLinus Torvalds
This fixes diff-tree sorting of directories vs files (we used to use just the regular cache_name_compare() which only works on full file pathnames).
2005-05-20Introduce "base_name_compare()" helper functionLinus Torvalds
This one compares two pathnames that may be partial basenames, not full paths. We need to get the path sorting right, since a directory name will sort as if it had the final '/' at the end.

2005-05-20[PATCH] diff overhaulJunio C Hamano
This cleans up the way calls are made into the diff core from diff-tree family and diff-helper. Earlier, these programs had "if (generating_patch)" sprinkled all over the place, but those ugliness are gone and handled uniformly from the diff core, even when not generating patch format. This also allowed diff-cache and diff-files to acquire -R (reverse) option to generate diff in reverse. Users of diff-tree can swap two trees easily so I did not add -R there. [ Linus' note: I'll add -R to "diff-tree" too, since a "commit diff" doesn't have another tree to switch around: the other tree is always the parent(s) of the commit ] Also -M<digits-as-mantissa> suggestion made by Linus has been implemented. Documentation updates are also included. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This moves the git manpage to man7, since "git" isn't a direct command per se. It also does two other things: * Sort of works around the asciidoc 6.0.3 bug where the manpages all get called "git.1". It just renames them to what they should have been called. * Fixes a cut-n-paste bug in git-diff-helper.txt that was making asciidoc choke.

2005-05-19[PATCH] Detect renames in diff family.Junio C Hamano
This rips out the rename detection engine from diff-helper and moves it to the diff core, and updates the internal calling convention used by diff-tree family into the diff core. In order to give the same option name to diff-tree family as well as to diff-helper, I've changed the earlier diff-helper '-r' option to '-M' (stands for Move; sorry but the natural abbreviation 'r' for 'rename' is already taken for 'recursive'). Although I did a fair amount of test with the git-diff-tree with existing rename commits in the core GIT repository, this should still be considered beta (preview) release. This patch depends on the diff-delta infrastructure just committed. This implements almost everything I wanted to see in this series of patch, except a few minor cleanups in the calling convention into diff core, but that will be a separate cleanup patch.
