* Move 'builtin-*' into a 'builtin/' subdirectoryLinus Torvalds2010-02-221-633/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shrinks the top-level directory a bit, and makes it much more pleasant to use auto-completion on the thing. Instead of [torvalds@nehalem git]$ em buil<tab> Display all 180 possibilities? (y or n) [torvalds@nehalem git]$ em builtin-sh builtin-shortlog.c builtin-show-branch.c builtin-show-ref.c builtin-shortlog.o builtin-show-branch.o builtin-show-ref.o [torvalds@nehalem git]$ em builtin-shor<tab> builtin-shortlog.c builtin-shortlog.o [torvalds@nehalem git]$ em builtin-shortlog.c you get [torvalds@nehalem git]$ em buil<tab> [type] builtin/ builtin.h [torvalds@nehalem git]$ em builtin [auto-completes to] [torvalds@nehalem git]$ em builtin/sh<tab> [type] shortlog.c shortlog.o show-branch.c show-branch.o show-ref.c show-ref.o [torvalds@nehalem git]$ em builtin/sho [auto-completes to] [torvalds@nehalem git]$ em builtin/shor<tab> [type] shortlog.c shortlog.o [torvalds@nehalem git]$ em builtin/shortlog.c which doesn't seem all that different, but not having that annoying break in "Display all 180 possibilities?" is quite a relief. NOTE! If you do this in a clean tree (no object files etc), or using an editor that has auto-completion rules that ignores '*.o' files, you won't see that annoying 'Display all 180 possibilities?' message - it will just show the choices instead. I think bash has some cut-off around 100 choices or something. So the reason I see this is that I'm using an odd editory, and thus don't have the rules to cut down on auto-completion. But you can simulate that by using 'ls' instead, or something similar. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* git fast-export: add --no-data optionGeoffrey Irving2009-07-311-1/+8
| | | | | | | | | | | | When using git fast-export and git fast-import to rewrite the history of a repository with large binary files, almost all of the time is spent dealing with blobs. This is extremely inefficient if all we want to do is rewrite the commits and tree structure. --no-data skips the output of blobs and writes SHA-1s instead of marks, which provides a massive speedup.

| * fast-export: Add a --tag-of-filtered-object option for newly dangling tagsElijah Newren2009-06-271-2/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When providing a list of paths to limit what is exported, the object that a tag points to can be filtered out entirely. This new switch allows the user to specify what should happen to the tag in such a case. The default action, 'abort' will exit with an error message. With 'drop', the tag will simply be omitted from the output. With 'rewrite', if the object tagged was a commit, the tag will be modified to tag an alternate commit. The alternate commit is determined by treating the original commit as the "parent" of the tag and then using the parent rewriting algorithm of the revision traversal machinery (related to the "--parents" option of "git rev-list") Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code expects a ref name to be provided in commit->util. While there was some code to set commit->util, it only worked in cases where there was an unbroken chain of revisions from a ref to the relevant commit. In cases such as running git fast-export --parents master -- COPYING commit->util would fail to be set. The old method of setting commit->util has been removed in favor of requesting show_source from the revision traversal machinery (related to the "--source" option of "git log" family of commands.) However, this change does not fix cases like git fast export master~1 or git fast export :/arguments since in such cases commit->util will be "master~1" or ":/arguments" while we need the actual ref (e.g. "refs/heads/master") Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | Commit c0582c53bcf4e83bba70e1ad23abbad31f96ebc8 introduced logic to just omit tags that point to tree objects. However, these objects were still being output and were pointing at "mark :0", which caused fast-import to crash.

* | fast-export: Avoid dropping files from commitsElijah Newren2009-03-251-1/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | When exporting a subset of commits on a branch that do not go back to a root commit (e.g. master~2..master), we still want each exported commit to have the same files in the exported tree as in the original tree. Previously, when given such a range, we would omit master~2 as a parent of master~1, but we would still diff against master~2 when selecting the list of files to include in master~1. This would result in only files that had changed in the given range showing up in the resulting export. In such cases, we should diff master~1 against the root instead (i.e. use diff_root_tree_sha1 instead of diff_tree_sha1). There's a special case to consider here: incremental exports (i.e. exports where the --import-marks flag is specified). If master~2 is an imported mark, then we still want to diff master~1 against master~2 when selecting the list of files to include. We can handle all cases, including the special case, by just checking whether master~2 corresponds to a known object mark when deciding what to diff against.

Alternatively, you can pass the option --fake-missing-tagger, forcing fast-export to fake a tagger Unspecified Tagger <no-tagger> with a tag date of the beginning of (Unix) time in the case of a missing tagger, so that fast-import is still able to import the result.

This patch extends the relevant programs to make them correctly process gitlinks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are exporting a commit which has no parents we may be doing it to a branch that already exists, causing fast-import to assume the branch's current revision should be the sole parent of the new commit. This can cause `git fast-export | git fast-import` to produce an incorrect graph for: A-------M----o------o refs/heads/master / B-+ In this graph A and B are initial commits (no parents) but if A was output first to refs/heads/master and then B is output fast-import would assume the graph was this instead: A-------M----o------o refs/heads/master \ / +-B-+ Which would cause B, M, and all later commits to have a different SHA-1, and obviously be quite a different graph. Sending a reset command prior to B informs fast-import to clear the implied parent of A, allowing B to remain an initial commit.

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>.

* Add 'git fast-export', the sister of 'git fast-import'Johannes Schindelin2007-12-021-0/+406
This program dumps (parts of) a git repository in the format that fast-import understands. For clarity's sake, it does not use the 'inline' method of specifying blobs in the commits, but builds the blobs before building the commits. Since signed tags' signatures will not necessarily be valid (think transformations after the export, or excluding revisions, changing the history), there are 4 modes to handle them: abort (default), ignore, warn and strip. The latter just turns the tags into unsigned ones. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
