From 60d02ccc18408e54ace8692532fcc73d4035b3c2 Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Thu, 6 Jul 2006 00:14:16 -0700 Subject: git-svn: migrate out of contrib Allow NO_SVN_TESTS to be defined to skip git-svn tests. These tests are time-consuming due to SVN being slow, and even more so if SVN Perl libraries are not available.

The were designed +with very different goals in mind. + +git-svn is designed for an individual developer who wants a +bidirectional flow of changesets between a single branch in Subversion +and an arbitrary number of branches in git. git-svnimport is designed +for read-only operation on repositories that match a particular layout +(albeit the recommended one by SVN developers). + +For importing svn, git-svnimport is potentially more powerful when +operating on repositories organized under the recommended +trunk/branch/tags structure, and should be faster, too. + +git-svn mostly ignores the very limited view of branching that +Subversion has. This allows git-svn to be much easier to use, +especially on repositories that are not organized in a manner that +git-svnimport is designed for. + +COMMANDS +-------- +init:: + Creates an empty git repository with additional metadata + directories for git-svn. The Subversion URL must be specified + as a command-line argument. + +fetch:: + Fetch unfetched revisions from the Subversion URL we are + tracking. refs/remotes/git-svn will be updated to the + latest revision. + + Note: You should never attempt to modify the remotes/git-svn + branch outside of git-svn. Instead, create a branch from + remotes/git-svn and work on that branch. Use the 'commit' + command (see below) to write git commits back to + remotes/git-svn. + + See 'Additional Fetch Arguments' if you are interested in + manually joining branches on commit. + +commit:: + Commit specified commit or tree objects to SVN. This relies on + your imported fetch data being up-to-date. This makes + absolutely no attempts to do patching when committing to SVN, it + simply overwrites files with those specified in the tree or + commit. All merging is assumed to have taken place + independently of git-svn functions. + +rebuild:: + Not a part of daily usage, but this is a useful command if + you've just cloned a repository (using git-clone) that was + tracked with git-svn. Unfortunately, git-clone does not clone + git-svn metadata and the svn working tree that git-svn uses for + its operations. This rebuilds the metadata so git-svn can + resume fetch operations. A Subversion URL may be optionally + specified at the command-line if the directory/repository you're + tracking has moved or changed protocols. + +show-ignore:: + Recursively finds and lists the svn:ignore property on + directories. The output is suitable for appending to + the $GIT_DIR/info/exclude file. + +OPTIONS +------- +-r :: +--revision :: + Only used with the 'fetch' command. + + Takes any valid -r svn would accept and passes it + directly to svn. -r: ranges and "{" DATE "}" syntax + is also supported. This is passed directly to svn, see svn + documentation for more details. + + This can allow you to make partial mirrors when running fetch. + +-:: +--stdin:: + Only used with the 'commit' command. + + Read a list of commits from stdin and commit them in reverse + order. Only the leading sha1 is read from each line, so + git-rev-list --pretty=oneline output can be used. + +--rmdir:: + Only used with the 'commit' command. + + Remove directories from the SVN tree if there are no files left + behind. SVN can version empty directories, and they are not + removed by default if there are no files left in them. git + cannot version empty directories. Enabling this flag will make + the commit to SVN act like git. + + repo-config key: svn.rmdir + +-e:: +--edit:: + Only used with the 'commit' command. + + Edit the commit message before committing to SVN. This is off by + default for objects that are commits, and forced on when committing + tree objects. + + repo-config key: svn.edit + +-l:: +--find-copies-harder:: + Both of these are only used with the 'commit' command. + + They are both passed directly to git-diff-tree see + git-diff-tree(1) for more information. + + repo-config key: svn.l + repo-config key: svn.findcopiesharder + +-A:: +--authors-file=:: + + Syntax is compatible with the files used by git-svnimport and + git-cvsimport: + +------------------------------------------------------------------------ +loginname = Joe User +------------------------------------------------------------------------ + + If this option is specified and git-svn encounters an SVN + committer name that does not exist in the authors-file, git-svn + will abort operation. The user will then have to add the + appropriate entry. Re-running the previous git-svn command + after the authors-file is modified should continue operation. + + repo-config key: svn.authors-file + +ADVANCED OPTIONS +---------------- +-b:: +--branch :: + Used with 'fetch' or 'commit'. + + This can be used to join arbitrary git branches to remotes/git-svn + on new commits where the tree object is equivalent. + + When used with different GIT_SVN_ID values, tags and branches in + SVN can be tracked this way, as can some merges where the heads + end up having completely equivalent content. This can even be + used to track branches across multiple SVN _repositories_. + + This option may be specified multiple times, once for each + branch. + + repo-config key: svn.branch + +-i:: +--id :: + This sets GIT_SVN_ID (instead of using the environment). See + the section on "Tracking Multiple Repositories or Branches" for + more information on using GIT_SVN_ID. + +COMPATIBILITY OPTIONS +--------------------- +--upgrade:: + Only used with the 'rebuild' command. + + Run this if you used an old version of git-svn that used + "git-svn-HEAD" instead of "remotes/git-svn" as the branch + for tracking the remote. + +--no-ignore-externals:: + Only used with the 'fetch' and 'rebuild' command. + + By default, git-svn passes --ignore-externals to svn to avoid + fetching svn:external trees into git. Pass this flag to enable + externals tracking directly via git. + + Versions of svn that do not support --ignore-externals are + automatically detected and this flag will be automatically + enabled for them. + + Otherwise, do not enable this flag unless you know what you're + doing. + + repo-config key: svn.noignoreexternals + +Basic Examples +~~~~~~~~~~~~~~ + +Tracking and contributing to an Subversion managed-project: + +------------------------------------------------------------------------ +# Initialize a tree (like git init-db): + git-svn init http://svn.foo.org/project/trunk +# Fetch remote revisions: + git-svn fetch +# Create your own branch to hack on: + git checkout -b my-branch remotes/git-svn +# Commit only the git commits you want to SVN: + git-svn commit [ ...] +# Commit all the git commits from my-branch that don't exist in SVN: + git-svn commit remotes/git-svn..my-branch +# Something is committed to SVN, pull the latest into your branch: + git-svn fetch && git pull . remotes/git-svn +# Append svn:ignore settings to the default git exclude file: + git-svn show-ignore >> .git/info/exclude +------------------------------------------------------------------------ + +DESIGN PHILOSOPHY +----------------- +Merge tracking in Subversion is lacking and doing branched development +with Subversion is cumbersome as a result. git-svn completely forgoes +any automated merge/branch tracking on the Subversion side and leaves it +entirely up to the user on the git side. It's simply not worth it to do +a useful translation when the the original signal is weak. + +TRACKING MULTIPLE REPOSITORIES OR BRANCHES +------------------------------------------ +This is for advanced users, most users should ignore this section. + +Because git-svn does not care about relationships between different +branches or directories in a Subversion repository, git-svn has a simple +hack to allow it to track an arbitrary number of related _or_ unrelated +SVN repositories via one git repository. Simply set the GIT_SVN_ID +environment variable to a name other other than "git-svn" (the default) +and git-svn will ignore the contents of the $GIT_DIR/git-svn directory +and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that +invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of +remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified +by the user outside of git-svn commands. + +ADDITIONAL FETCH ARGUMENTS +-------------------------- +This is for advanced users, most users should ignore this section. + +Unfetched SVN revisions may be imported as children of existing commits +by specifying additional arguments to 'fetch'. Additional parents may +optionally be specified in the form of sha1 hex sums at the +command-line. Unfetched SVN revisions may also be tied to particular +git commits with the following syntax: + + svn_revision_number=git_commit_sha1 + +This allows you to tie unfetched SVN revision 375 to your current HEAD:: + + `git-svn fetch 375=$(git-rev-parse HEAD)` + +Advanced Example: Tracking a Reorganized Repository +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +If you're tracking a directory that has moved, or otherwise been +branched or tagged off of another directory in the repository and you +care about the full history of the project, then you can read this +section. + +This is how Yann Dirson tracked the trunk of the ufoai directory when +the /trunk directory of his repository was moved to /ufoai/trunk and +he needed to continue tracking /ufoai/trunk where /trunk left off. + +------------------------------------------------------------------------ + # This log message shows when the repository was reorganized: + r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line + Changed paths: + D /trunk + A /ufoai/trunk (from /trunk:165) + + # First we start tracking the old revisions: + GIT_SVN_ID=git-oldsvn git-svn init \ + https://svn.sourceforge.net/svnroot/ufoai/trunk + GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165 + + # And now, we continue tracking the new revisions: + GIT_SVN_ID=git-newsvn git-svn init \ + https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk + GIT_SVN_ID=git-newsvn git-svn fetch \ + 166=`git-rev-parse refs/remotes/git-oldsvn` +------------------------------------------------------------------------ + +BUGS +---- +If somebody commits a conflicting changeset to SVN at a bad moment +(right before you commit) causing a conflict and your commit to fail, +your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The +easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and +run 'rebuild'. + +We ignore all SVN properties except svn:executable. Too difficult to +map them since we rely heavily on git write-tree being _exactly_ the +same on both the SVN and git working trees and I prefer not to clutter +working trees with metadata files. + +svn:keywords can't be ignored in Subversion (at least I don't know of +a way to ignore them). + +Renamed and copied directories are not detected by git and hence not +tracked when committing to SVN. I do not plan on adding support for +this as it's quite difficult and time-consuming to get working for all +the possible corner cases (git doesn't do it, either). Renamed and +copied files are fully supported if they're similar enough for git to +detect them. + +Author +------ +Written by Eric Wong . + +Documentation +------------- +Written by Eric Wong . diff --git a/Makefile b/Makefile index 202f26171..a0e90c012 100644 --- a/Makefile +++ b/Makefile @@ -33,6 +33,10 @@ all: # Define NO_SYMLINK_HEAD if you never want .git/HEAD to be a symbolic link. # Enable it on Windows.

The were designed -with very different goals in mind. - -git-svn is designed for an individual developer who wants a -bidirectional flow of changesets between a single branch in Subversion -and an arbitrary number of branches in git. git-svnimport is designed -for read-only operation on repositories that match a particular layout -(albeit the recommended one by SVN developers). - -For importing svn, git-svnimport is potentially more powerful when -operating on repositories organized under the recommended -trunk/branch/tags structure, and should be faster, too. - -git-svn mostly ignores the very limited view of branching that -Subversion has. This allows git-svn to be much easier to use, -especially on repositories that are not organized in a manner that -git-svnimport is designed for. - -COMMANDS --------- -init:: - Creates an empty git repository with additional metadata - directories for git-svn. The Subversion URL must be specified - as a command-line argument. - -fetch:: - Fetch unfetched revisions from the Subversion URL we are - tracking. refs/remotes/git-svn will be updated to the - latest revision. - - Note: You should never attempt to modify the remotes/git-svn - branch outside of git-svn. Instead, create a branch from - remotes/git-svn and work on that branch. Use the 'commit' - command (see below) to write git commits back to - remotes/git-svn. - - See 'Additional Fetch Arguments' if you are interested in - manually joining branches on commit. - -commit:: - Commit specified commit or tree objects to SVN. This relies on - your imported fetch data being up-to-date. This makes - absolutely no attempts to do patching when committing to SVN, it - simply overwrites files with those specified in the tree or - commit. All merging is assumed to have taken place - independently of git-svn functions. - -rebuild:: - Not a part of daily usage, but this is a useful command if - you've just cloned a repository (using git-clone) that was - tracked with git-svn. Unfortunately, git-clone does not clone - git-svn metadata and the svn working tree that git-svn uses for - its operations. This rebuilds the metadata so git-svn can - resume fetch operations. A Subversion URL may be optionally - specified at the command-line if the directory/repository you're - tracking has moved or changed protocols. - -show-ignore:: - Recursively finds and lists the svn:ignore property on - directories. The output is suitable for appending to - the $GIT_DIR/info/exclude file. - -OPTIONS -------- --r :: ---revision :: - Only used with the 'fetch' command. - - Takes any valid -r svn would accept and passes it - directly to svn. -r: ranges and "{" DATE "}" syntax - is also supported. This is passed directly to svn, see svn - documentation for more details. - - This can allow you to make partial mirrors when running fetch. - --:: ---stdin:: - Only used with the 'commit' command. - - Read a list of commits from stdin and commit them in reverse - order. Only the leading sha1 is read from each line, so - git-rev-list --pretty=oneline output can be used. - ---rmdir:: - Only used with the 'commit' command. - - Remove directories from the SVN tree if there are no files left - behind. SVN can version empty directories, and they are not - removed by default if there are no files left in them. git - cannot version empty directories. Enabling this flag will make - the commit to SVN act like git. - - repo-config key: svn.rmdir - --e:: ---edit:: - Only used with the 'commit' command. - - Edit the commit message before committing to SVN. This is off by - default for objects that are commits, and forced on when committing - tree objects. - - repo-config key: svn.edit - --l:: ---find-copies-harder:: - Both of these are only used with the 'commit' command. - - They are both passed directly to git-diff-tree see - git-diff-tree(1) for more information. - - repo-config key: svn.l - repo-config key: svn.findcopiesharder - --A:: ---authors-file=:: - - Syntax is compatible with the files used by git-svnimport and - git-cvsimport: - ------------------------------------------------------------------------- -loginname = Joe User ------------------------------------------------------------------------- - - If this option is specified and git-svn encounters an SVN - committer name that does not exist in the authors-file, git-svn - will abort operation. The user will then have to add the - appropriate entry. Re-running the previous git-svn command - after the authors-file is modified should continue operation. - - repo-config key: svn.authors-file - -ADVANCED OPTIONS ----------------- --b:: ---branch :: - Used with 'fetch' or 'commit'. - - This can be used to join arbitrary git branches to remotes/git-svn - on new commits where the tree object is equivalent. - - When used with different GIT_SVN_ID values, tags and branches in - SVN can be tracked this way, as can some merges where the heads - end up having completely equivalent content. This can even be - used to track branches across multiple SVN _repositories_. - - This option may be specified multiple times, once for each - branch. - - repo-config key: svn.branch - --i:: ---id :: - This sets GIT_SVN_ID (instead of using the environment). See - the section on "Tracking Multiple Repositories or Branches" for - more information on using GIT_SVN_ID. - -COMPATIBILITY OPTIONS ---------------------- ---upgrade:: - Only used with the 'rebuild' command. - - Run this if you used an old version of git-svn that used - "git-svn-HEAD" instead of "remotes/git-svn" as the branch - for tracking the remote. - ---no-ignore-externals:: - Only used with the 'fetch' and 'rebuild' command. - - By default, git-svn passes --ignore-externals to svn to avoid - fetching svn:external trees into git. Pass this flag to enable - externals tracking directly via git. - - Versions of svn that do not support --ignore-externals are - automatically detected and this flag will be automatically - enabled for them. - - Otherwise, do not enable this flag unless you know what you're - doing. - - repo-config key: svn.noignoreexternals - -Basic Examples -~~~~~~~~~~~~~~ - -Tracking and contributing to an Subversion managed-project: - ------------------------------------------------------------------------- -# Initialize a tree (like git init-db): - git-svn init http://svn.foo.org/project/trunk -# Fetch remote revisions: - git-svn fetch -# Create your own branch to hack on: - git checkout -b my-branch remotes/git-svn -# Commit only the git commits you want to SVN: - git-svn commit [ ...] -# Commit all the git commits from my-branch that don't exist in SVN: - git-svn commit remotes/git-svn..my-branch -# Something is committed to SVN, pull the latest into your branch: - git-svn fetch && git pull . remotes/git-svn -# Append svn:ignore settings to the default git exclude file: - git-svn show-ignore >> .git/info/exclude ------------------------------------------------------------------------- - -DESIGN PHILOSOPHY ------------------ -Merge tracking in Subversion is lacking and doing branched development -with Subversion is cumbersome as a result. git-svn completely forgoes -any automated merge/branch tracking on the Subversion side and leaves it -entirely up to the user on the git side. It's simply not worth it to do -a useful translation when the the original signal is weak. - -TRACKING MULTIPLE REPOSITORIES OR BRANCHES ------------------------------------------- -This is for advanced users, most users should ignore this section. - -Because git-svn does not care about relationships between different -branches or directories in a Subversion repository, git-svn has a simple -hack to allow it to track an arbitrary number of related _or_ unrelated -SVN repositories via one git repository. Simply set the GIT_SVN_ID -environment variable to a name other other than "git-svn" (the default) -and git-svn will ignore the contents of the $GIT_DIR/git-svn directory -and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that -invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of -remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified -by the user outside of git-svn commands. - -ADDITIONAL FETCH ARGUMENTS --------------------------- -This is for advanced users, most users should ignore this section. - -Unfetched SVN revisions may be imported as children of existing commits -by specifying additional arguments to 'fetch'. Additional parents may -optionally be specified in the form of sha1 hex sums at the -command-line. Unfetched SVN revisions may also be tied to particular -git commits with the following syntax: - - svn_revision_number=git_commit_sha1 - -This allows you to tie unfetched SVN revision 375 to your current HEAD:: - - `git-svn fetch 375=$(git-rev-parse HEAD)` - -Advanced Example: Tracking a Reorganized Repository -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -If you're tracking a directory that has moved, or otherwise been -branched or tagged off of another directory in the repository and you -care about the full history of the project, then you can read this -section. - -This is how Yann Dirson tracked the trunk of the ufoai directory when -the /trunk directory of his repository was moved to /ufoai/trunk and -he needed to continue tracking /ufoai/trunk where /trunk left off. - ------------------------------------------------------------------------- - # This log message shows when the repository was reorganized: - r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line - Changed paths: - D /trunk - A /ufoai/trunk (from /trunk:165) - - # First we start tracking the old revisions: - GIT_SVN_ID=git-oldsvn git-svn init \ - https://svn.sourceforge.net/svnroot/ufoai/trunk - GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165 - - # And now, we continue tracking the new revisions: - GIT_SVN_ID=git-newsvn git-svn init \ - https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk - GIT_SVN_ID=git-newsvn git-svn fetch \ - 166=`git-rev-parse refs/remotes/git-oldsvn` ------------------------------------------------------------------------- - -BUGS ----- -If somebody commits a conflicting changeset to SVN at a bad moment -(right before you commit) causing a conflict and your commit to fail, -your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The -easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and -run 'rebuild'. - -We ignore all SVN properties except svn:executable. Too difficult to -map them since we rely heavily on git write-tree being _exactly_ the -same on both the SVN and git working trees and I prefer not to clutter -working trees with metadata files. - -svn:keywords can't be ignored in Subversion (at least I don't know of -a way to ignore them). - -Renamed and copied directories are not detected by git and hence not -tracked when committing to SVN. I do not plan on adding support for -this as it's quite difficult and time-consuming to get working for all -the possible corner cases (git doesn't do it, either). Renamed and -copied files are fully supported if they're similar enough for git to -detect them. - -Author ------- -Written by Eric Wong . - -Documentation -------------- -Written by Eric Wong . diff --git a/contrib/git-svn/t/lib-git-svn.sh b/contrib/git-svn/t/lib-git-svn.sh deleted file mode 100644 index d7f972a0c..000000000 --- a/contrib/git-svn/t/lib-git-svn.sh +++ /dev/null @@ -1,45 +0,0 @@ -PATH=$PWD/../:$PATH -if test -d ../../../t -then - cd ../../../t -else - echo "Must be run in contrib/git-svn/t" >&2 - exit 1 -fi - -. ./test-lib.sh - -GIT_DIR=$PWD/.git -GIT_SVN_DIR=$GIT_DIR/svn/git-svn -SVN_TREE=$GIT_SVN_DIR/svn-tree - -svnadmin >/dev/null 2>&1 -if test $? != 1 -then - test_expect_success 'skipping contrib/git-svn test' : - test_done - exit -fi - -svn >/dev/null 2>&1 -if test $? != 1 -then - test_expect_success 'skipping contrib/git-svn test' : - test_done - exit -fi - -svnrepo=$PWD/svnrepo - -set -e - -if svnadmin create --help | grep fs-type >/dev/null -then - svnadmin create --fs-type fsfs "$svnrepo" -else - svnadmin create "$svnrepo" -fi - -svnrepo="file://$svnrepo/test-git-svn" - - diff --git a/contrib/git-svn/t/t0000-contrib-git-svn.sh b/contrib/git-svn/t/t0000-contrib-git-svn.sh deleted file mode 100644 index b482bb64c..000000000 --- a/contrib/git-svn/t/t0000-contrib-git-svn.sh +++ /dev/null @@ -1,232 +0,0 @@ -#!/bin/sh -# -# Copyright (c) 2006 Eric Wong -# - -test_description='git-svn tests' -GIT_SVN_LC_ALL=$LC_ALL - -case "$LC_ALL" in -*.UTF-8) - have_utf8=t - ;; -*) - have_utf8= - ;; -esac - -. ./lib-git-svn.sh - -mkdir import -cd import - -echo foo > foo -if test -z "$NO_SYMLINK" -then - ln -s foo foo.link -fi -mkdir -p dir/a/b/c/d/e -echo 'deep dir' > dir/a/b/c/d/e/file -mkdir -p bar -echo 'zzz' > bar/zzz -echo '#!/bin/sh' > exec.sh -chmod +x exec.sh -svn import -m 'import for git-svn' .
