Elijah Newren	ebeec7dbc5	fast-export: Avoid dropping files from commits 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.

Elijah Newren	784f8affe4	fast-export: ensure we traverse commits in topological order fast-export will only list as parents those commits which have already been traversed (making it appear as if merges have been squashed if not all parents have been traversed). To avoid this silent squashing of merge commits, we request commits in topological order.

Johannes Schindelin	4e46a8d62c	fast-export: deal with tag objects that do not have a tagger When no tagger was found (old Git produced tags like this), no "tagger" line is printed (but this is incompatible with the current git fast-import). 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.

Johannes Schindelin	2075ffb58e	fast-export: use an unsorted string list for extra_refs The list extra_refs contains tags and the objects referenced by them, so that they can be handled at the end. When a tag references a commit, that commit is added to the list using the same name. Also, the function handle_tags_and_duplicates() relies on the order the items were added to extra_refs, so clearly we do not want to use a sorted list here. Noticed by Miklos Vajna.

Alexander Gavrilov	ae7c5dcef9	Support copy and rename detection in fast-export.

Johannes Schindelin	c455c87c5c	Rename path_list to string_list 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".

Alexander Gavrilov	03db4525d3	Support gitlinks in fast-import. 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.

Stephan Beyer	1b1dd23f2d	Make usage strings dash-less 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.

Pieter de Bie	df6a7ff7ac	builtin-fast-export: Add importing and exporting of revision marks 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.

Shawn O. Pearce	d8933f013a	fast-export: Correctly generate initial commits with no parents 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.

Johannes Schindelin	ef90d6d420	Provide git_config with a callback-data parameter git_config() only had a function parameter, but no callback data parameter.

Jim Meyering	8e0f70033b	Avoid unnecessary "if-before-free" tests. 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$\s(\S+?)(?:\s!=\sNULL)?\s$\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>.

Johannes Schindelin	f2dc849e9c	Add 'git fast-export', the sister of 'git fast-import' 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>	17 years ago
