* Support copy and rename detection in fast-export.Alexander Gavrilov2008-07-29
| | | | | | | | | | | | Although it does not matter for Git itself, tools that export to systems that explicitly track copies and renames can benefit from such information. This patch makes fast-export output correct action logs when -M or -C are enabled. Signed-off-by: Alexander Gavrilov <angavrilov@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Rename path_list to string_listJohannes Schindelin2008-07-21
| | | | | | | | | | | | | | | | | | | | | | | The name path_list was correct for the first usage of that data structure, but it really is a general-purpose string list. $ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list) $ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list) $ git mv path-list.h string-list.h $ git mv path-list.c string-list.c $ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path) $ perl -i -pe 's/path/string/g' string-list.[ch] $ git mv Documentation/technical/api-path-list.txt \ Documentation/technical/api-string-list.txt $ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths) ... and then fix all users of string-list to access the member "string" instead of "path". Documentation/technical/api-string-list.txt needed some rewrapping, too. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Support gitlinks in fast-import.Alexander Gavrilov2008-07-19
| | | | | | | | | | | | | | | | | | | | | | | | Currently fast-import/export cannot be used for repositories with submodules. This patch extends the relevant programs to make them correctly process gitlinks. Links can be represented by two forms of the Modify command: M 160000 SHA1 some/path which sets the link target explicitly, or M 160000 :mark some/path where the mark refers to a commit. The latter form can be used by importing tools to build all submodules simultaneously in one physical repository, and then simply fetch them apart.

* Make usage strings dash-lessStephan Beyer2008-07-13
| | | | | | | | | | | | | | | 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.

* Fix some warnings (on cygwin) to allow -WerrorRamsay Jones2008-07-05
| | | | | | | | | When printing valuds of type uint32_t, we should use PRIu32, and should not assume that it is unsigned int. On 32-bit platforms, it could be defined as unsigned long. The same caution applies to ntohl(). Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* fast-export --export-marks: fix off by one errorJunio C Hamano2008-07-03
| | | | | | | | | | The export_marks() function iterated over a (potentially sparsely populated) hashtable, but it accessed it starting from offset 1 and one element beyond the end. Noticed by SungHyun Nam. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* builtin-fast-export: Add importing and exporting of revision marksPieter de Bie2008-06-19
| | | | | | | | | | | This adds the --import-marks and --export-marks to fast-export. These import and export the marks used to for all revisions exported in a similar fashion to what fast-import does. The format is the same as fast-import, so you can create a bidirectional importer / exporter by using the same marks file on both sides.

* fast-export: Correctly generate initial commits with no parentsShawn O. Pearce2008-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | Provide git_config with a callback-data parameterJohannes Schindelin2008-05-14
|/ / | | | | | | | | | | | | | | | | | | | | | | git_config() only had a function parameter, but no callback data parameter. This assumes that all callback functions only modify global variables.

| * | Avoid unnecessary "if-before-free" tests.Jim Meyering2008-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change removes all obvious useless if-before-free tests. 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 Schindelin2007-12-02
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>
