2005-06-27[PATCH] Remove "delta" object representation.Libravatar Junio C Hamano7-80/+1
Packed delta files created by git-pack-objects seems to be the way to go, and existing "delta" object handling code has exposed the object representation details to too many places. Remove it while we refactor code to come up with a proper interface in sha1_file.c. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-06-19[PATCH] Rework -B output.Libravatar Junio C Hamano1-0/+9
Patch for a completely rewritten file detected by the -B flag was shown as a pair of creation followed by deletion in earlier versions. This was an misguided attempt to make reviewing such a complete rewrite easier, and unnecessarily ended up confusing git-apply. Instead, show the entire contents of old version prefixed with '-', followed by the entire contents of new version prefixed with '+'. This gives the same easy-to-review for human consumer while keeping it a single, regular modification patch for machine consumption, something that even GNU patch can grok.

2005-06-06[PATCH] Document git-ssh-pull and git-ssh-pushLibravatar Daniel Barkalow2-11/+45
This fixes the documentation for git-ssh-push, as called by users (if you run git-ssh-pull or git-ssh-push on one machine, the other runs on the other machine, and they transfer data in the specified direction). This also adds documentation for the -w option and for using filenames for the commit-id (which does what you'd want: uses the source side's value, not the value already on the target, even if you're running it on the target). It also credits me with the programs and the documentation for git-ssh-push. Someone who knows asciidoc should make sure I didn't mess up the formatting. I'm only sure of the ascii part.

2005-06-06[PATCH] Modify git-rev-list to linearise the commit history in merge order.Libravatar jon@blackcubes.dyndns.org1-1/+29
This patch linearises the GIT commit history graph into merge order which is defined by invariants specified in Documentation/git-rev-list.txt. The linearisation produced by this patch is superior in an objective sense to that produced by the existing git-rev-list implementation in that the linearisation produced is guaranteed to have the minimum number of discontinuities, where a discontinuity is defined as an adjacent pair of commits in the output list which are not related in a direct child-parent relationship. With this patch a graph like this: a4 --- | \ \ | b4 | |/ | | a3 | | | | | a2 | | | | c3 | | | | | c2 | b3 | | | /| | b2 | | | c1 | | / | b1 a1 | | | a0 | | / root Sorts like this: = a4 | c3 | c2 | c1 ^ b4 | b3 | b2 | b1 ^ a3 | a2 | a1 | a0 = root Instead of this: = a4 | c3 ^ b4 | a3 ^ c2 ^ b3 ^ a2 ^ b2 ^ c1 ^ a1 ^ b1 ^ a0 = root A test script, t/t6000-rev-list.sh, includes a test which demonstrates that the linearisation produced by --merge-order has less discontinuities than the linearisation produced by git-rev-list without the --merge-order flag specified. To see this, do the following: cd t ./t6000-rev-list.sh cd trash cat actual-default-order cat actual-merge-order The existing behaviour of git-rev-list is preserved, by default. To obtain the modified behaviour, specify --merge-order or --merge-order --show-breaks on the command line. This version of the patch has been tested on the git repository and also on the linux-2.6 repository and has reasonable performance on both - ~50-100% slower than the original algorithm. This version of the patch has incorporated a functional equivalent of the Linus' output limiting algorithm into the merge-order algorithm itself. This operates per the notes associated with Linus' commit 337cb3fb8da45f10fe9a0c3cf571600f55ead2ce. This version has incorporated Linus' feedback regarding proposed changes to rev-list.c. (see: [PATCH] Factor out filtering in rev-list.c) This version has improved the way sort_first_epoch marks commits as uninteresting.

2005-06-05[PATCH] pull: gracefully recover from delta retrieval failure.Libravatar Junio C Hamano3-3/+12
This addresses a concern raised by Jason McMullan in the mailing list discussion. After retrieving and storing a potentially deltified object, pull logic tries to check and fulfil its delta dependency. When the pull procedure is killed at this point, however, there was no easy way to recover by re-running pull, since next run would have found that we already have that deltified object and happily reported success, without really checking its delta dependency is satisfied. This patch introduces --recover option to git-*-pull family which causes them to re-validate dependency of deltified objects we are fetching. A new test t5100-delta-pull.sh covers such a failure mode. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-03[PATCH] diff: Fix docs and add -O to diff-helper.Libravatar Junio C Hamano4-4/+9
This patch updates diff documentation and usage strings: - clarify the semantics of -R. It is not "output in reverse"; rather, it is "I will feed diff backwards". Semantically they are different when -C is involved. - describe -O in usage strings of diff-* brothers. It was implemented, documented but not described in usage text. Also it adds -O to diff-helper. Like -S (and unlike -M/-C/-B), this option can work on sanitized diff-raw output produced by the diff-* brothers. While we are at it, the call it makes to diffcore is cleaned up to use the diffcore_std() like everybody else, and the declaration for the low level diffcore routines are moved from diff.h (public) to diffcore.h (private between diff.c and diffcore backends).

2005-06-02[PATCH] Handle deltified object correctly in git-*-pull family.Libravatar Junio C Hamano3-3/+15
When a remote repository is deltified, we need to get the objects that a deltified object we want to obtain is based upon. The initial parts of each retrieved SHA1 file is inflated and inspected to see if it is deltified, and its base object is asked from the remote side when it is. Since this partial inflation and inspection has a small performance hit, it can optionally be skipped by giving -d flag to git-*-pull commands. This flag should be used only when the remote repository is known to have no deltified objects. Rsync transport does not have this problem since it fetches everything the remote side has.

A new diffcore filter diffcore-order is introduced. This takes a text file each of whose line is a shell glob pattern.

2005-05-30[PATCH] Add -B flag to diff-* brothers.Libravatar Junio C Hamano3-3/+12
A new diffcore transformation, diffcore-break.c, is introduced. When the -B flag is given, a patch that represents a complete rewrite is broken into a deletion followed by a creation. This makes it easier to review such a complete rewrite patch. The -B flag takes the same syntax as the -M and -C flags to specify the minimum amount of non-source material the resulting file needs to have to be considered a complete rewrite, and defaults to 99% if not specified. As the new test t4008-diff-break-rewrite.sh demonstrates, if a file is a complete rewrite, it is broken into a delete/create pair, which can further be subjected to the usual rename detection if -M or -C is used. For example, if file0 gets completely rewritten to make it as if it were rather based on file1 which itself disappeared, the following happens: The original change looks like this: file0 --> file0' (quite different from file0) file1 --> /dev/null After diffcore-break runs, it would become this: file0 --> /dev/null /dev/null --> file0' file1 --> /dev/null Then diffcore-rename matches them up: file1 --> file0' The internal score values are finer grained now. Earlier maximum of 10000 has been raised to 60000; there is no user visible changes but there is no reason to waste available bits.

2005-05-30[PATCH] diff-helper: Fix R/C score parsing under -z flag.Libravatar Junio C Hamano1-1/+1
The score number that follow R/C status were parsed but the parse pointer was not updated, causing the entire line to become unrecognized. This patch fixes this problem. There was a test missing to catch this breakage, which this commit adds as t4009-diff-rename-4.sh. The diff-raw tests used in related t4005-diff-rename-2.sh (the same test without -z) and t4007-rename-3.sh were stricter than necessarily, despite that the comment for the tests said otherwise. This patch also corrects them. The documentation is updated to say that the status can optionally be followed by a number called "score"; it does not have to stay similarity index forever and there is no reason to limit it only to C and R.

2005-05-29[PATCH] Pickaxe fixes.Libravatar Junio C Hamano3-3/+16
A bug in the command line argument parsing code was making pickaxe not to work at all in diff-cache and diff-files commands.

2005-05-29[PATCH] Rewrite ls-tree to behave more like "/bin/ls -a"Libravatar Junio C Hamano1-8/+12
This is a complete rewrite of ls-tree to make it behave more like what "/bin/ls -a" does in the current working directory. Namely, the changes are: - Unlike the old ls-tree behaviour that used paths arguments to restrict output (not that it worked as intended---as pointed out in the mailing list discussion, it was quite incoherent), this rewrite uses paths arguments to specify what to show. - Without arguments, it implicitly uses the root level as its sole argument ("/bin/ls -a" behaves as if "." is given without argument). - Without -r (recursive) flag, it shows the named blob (either file or symlink), or the named tree and its immediate children. - With -r flag, it shows the named path, and recursively descends into it if it is a tree. - With -d flag, it shows the named path and does not show its children even if the path is a tree, nor descends into it recursively. This is still request-for-comments patch. There is no mailing list consensus that this proposed new behaviour is a good one. The patch to t/t3100-ls-tree-restrict.sh illustrates user-visible behaviour changes. Namely: * "git-ls-tree $tree path1 path0" lists path1 first and then path0. It used to use paths as an output restrictor and showed output in cache entry order (i.e. path0 first and then path1) regardless of the order of paths arguments. * "git-ls-tree $tree path2" lists path2 and its immediate children but having explicit paths argument does not imply recursive behaviour anymore, hence paths/baz is shown but not paths/baz/b.

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.

2005-05-21[PATCH] Introducing software archaeologist's tool "pickaxe".Libravatar Junio C Hamano4-4/+19
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.
