* git-svn: fix some potential bugs with --follow-parentEric Wong2007-02-231-1/+5
| | | | | | | | | | | | | | | | | When using do_switch: We only need to ensure the index is clean and set to that of the parent tree) we rely on being able to reconstruct full files with deltas transferred over the network. When using do_update: We may safely unlink the index if we are fetching an entire new tree with do_update. Having an old index (from a previously deleted/abandoned directory) around can cause irrelevant files to be mistakenly kept. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: fix reconnections to different paths of svn:// repositoriesEric Wong2007-02-231-0/+1
| | | | | | | | | | | | Clearing the pool of the previous SVN::Ra connection we have seems to to fix mysterious connection dropping errors when reconnecting to different paths of svn:// repositories hosted by rubyforge.org. Note: I'm not sure *why* this fixes things things, but it does for me. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: fix clone when a target directory has been specifiedEric Wong2007-02-231-7/+3
| | | | | | | | | | | | | Several bugs caused this to fail: * GIT_DIR was set incorrectly after entering the target directory * Avoid double chdir-ing when clone is called with an explicit path * create target subdirectory *before* running git-init when using the multi-init path Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: don't consider SVN URL usernames significant when comparingSam Vilain2007-02-231-0/+8
| | | | | | | | http://foo@blah.com/path is the same as http://blah.com/path, so remove usernames from URLs before storing them in commits, and when reading them from commits. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: ensure we're at the top-level and can access $GIT_DIREric Wong2007-02-231-0/+23
| | | | | | | | | | | If we are run inside a subdirectory of a working tree, we'll chdir to the top first before touching anything. This also prevents the accidental creation of .git directories inside subdirectories since they need metadata. Noticed by maio on #git Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: give show-ignore HEAD smarts, like dcommit and logEric Wong2007-02-231-1/+3
| | | | | | | | | This allows the user to run git-svn show-ignore on there current HEAD without needing to remember which branch/ref they branched from with -i. Also, find_by_url should correctly handle cases where the URL passed to it is not valid. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: allow metadata options to be specified with 'init' and 'clone'Eric Wong2007-02-231-0/+13
| | | | | | | | | | | | | Since the options that affect the way metadata is handled in git-svn, should be consistently set/unset throughout history imported by git-svn; it makes sense to allow the user to set certain options from the command-line that will write to the config file when initially creating the repository. Also, fix some formatting issues while we're updating documentation. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: fix useSvmProps, hopefully for the last timeEric Wong2007-02-231-34/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | svm:mirror is not useful at all for us. Parts of the old unit test were broken and based on my misunderstanding of the svm:mirror property. When we read svm:source; make sure we correctly handle the '!' in it: it is used to separate the path of the repository root from the virtual path within the repository. We don't need to make that distinction, honestly! We also ensure that subdirectories are also mirrored with the correct URL if we're using useSvmProps. We have a new test that uses dumped repo that was really created using SVN::Mirror to avoid ambiguities and mis-understandings about the svm: properties. Note: trailing whitespace in the svm.dump file is unfortunately a reality and required by SVN; so please ignore it when applying this patch. Also, ensure that the -R/--remote/--svn-remote flag is always in effect if explicitly passed via the command-line. This allows us to track logically different mirrors sharing the same URL (probably common with SVN::Mirror/SVK users). Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: add support for using svnsync propertiesEric Wong2007-02-231-2/+58
| | | | | | | | | | | | This is similar to useSvmProps, but far simpler in implementation because svnsync retains a 1:1 between revision numbers and relative paths within the repository Config keys: svn.useSvnsyncProps svn-remote.<repo>.useSvnsyncProps Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: allow overriding of the SVN repo root in metadataEric Wong2007-02-231-1/+25
| | | | | | | | | | | | This feature allows users to create repositories from alternate URLs. For example, an administrator could run git-svn on the server locally (accessing via file://) but wish to distribute the repository with a public http:// or svn:// URL in the metadata so users of it will see the public URL. Config key: svn-remote.<remote>.rewriteRoot Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: add 'clone' command, an alias for init + fetchEric Wong2007-02-231-1/+20
| | | | Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: hide the private git-svn 'config' file as '.metadata'Eric Wong2007-02-231-1/+6
| | | | | | | | | | | Having it named as 'config' prevents us from tracking a ref named 'config', which is a huge mistake. On the non-technical side, the word 'config' implies that a user can freely modify it; but that's not the case here. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: fix some issues for people migrating from older versionsEric Wong2007-02-231-4/+6
| | | | | | | | | | * Fixed logic for renaming old .rev_db -> .rev_db.$uuid * correctly handle manual migrations for those who decide to start use globbing to handle branches/tags over individual 'fetch' keys Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: add a 'rebase' commandEric Wong2007-02-231-28/+63
| | | | | | | | | | | | | | | | This works similarly to 'svn update' or 'git pull' except that it preserves linear history with 'git rebase' instead of 'git merge' for ease of dcommit-ing with git-svn. While we're at it, put the working_head_info() logic into its own function and allow --fetch-all/--all for dcommit and rebase (which will fetch all refs in the current [svn-remote] instead of just the working one). Note that the '-a' switch (short for --fetch-all/--all) has been removed as it conflicts with the non-svn 'git fetch' Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: checkout files on new fetchesEric Wong2007-02-231-2/+26
| | | | | | | | | | | | | On newly-created repositories, 'refs/heads/master' does not point to anything. This can be confusing to new users; so we update 'master' to point to the last imported ref after fetching is done. Once 'master' is valid; we assume HEAD points to it; and if the repository is not bare, then checkout the files if the working tree is clean and unused. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: add support for --stat in the log commandEric Wong2007-02-231-2/+9
| | | | Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: documentation updates for new functionalityEric Wong2007-02-231-2/+3
| | | | | | | | | | Force the showing of the --minimize flag as an option in the 'migrate' help. Also, fix the usage function to correctly filter out the deprecated aliases. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: allow dcommit for those who only fetch from SVM with useSvmPropsEric Wong2007-02-231-2/+8
| | | | | | | | | | | This allows users to use SVM (SVN::Mirror) to mirror a remote repository to use dcommit to commit to the repository that SVM was mirroring. When dcommit is used in this manner, the automatic fetch + rebase/reset does not happen; in which case the user will have to manually invoke svm/svk, run 'git svn fetch', and finally 'git rebase'. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: error checking for invalid [svn-remote "..."] sectionsEric Wong2007-02-231-2/+3
| | | | | | | We don't end up trying to pass an undef URL over to SVN::Ra->new because it'll segfault. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: remember to check for clean indices on globbed refs, tooEric Wong2007-02-231-7/+8
| | | | | | | Also, warn about dirty indices and avoid an unncessary write-tree call if the index is clean. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: allow --log-window-size to be specified, default to 100Eric Wong2007-02-231-2/+7
| | | | | | | | | | The newer default value should should lower memory usage for large fetches and also help with fetching from less reliable servers. Previously the value was 1000 and memory usage got a bit high on some repositories and fetching became less reliable in some cases. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: simplify the (multi-)init methods of fetchingEric Wong2007-02-231-51/+35
| | | | | | | | Also, some changes to avoid creating dead dirs under .git/svn/. We now create all directories as late as possible. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: brown paper bag fixesEric Wong2007-02-231-2/+3
| | | | | | | | * avoid skipping modification-only changes in fetch * correctly fetch when we only have branches and tags to glob from (no fetch keys defined) Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: allow 'init' to act as multi-initEric Wong2007-02-231-20/+32
| | | | | | | | | | | | | multi-init is now just an alias that requires -T/-t/-b; all options that 'init' can now accept. This will hopefully simplify usage and reduce typing. Also, allow the --shared option in 'init' to take an optional argument now that 'git-init --shared' supports an optional argument. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: hopefully make 'fetch' more user-friendlyEric Wong2007-02-231-25/+33
| | | | | | | | | | | | | | | multi-fetch is deprecated, "fetch -a" is easier to type By default, fetch will fetch everything from its default [svn-remote]; if fetch [--all|-a] is specified, then it will fetch from all svn remotes. Refspecs on the command-line (like git-fetch) are not supported. Also, enable -r/--revision arguments for fetch so users can shoot themselves in the foot^W^W^W^W^W skip some history and do the equivalent of a shallow clone/fetch they're not interested in. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: usability fixes for the 'git svn log' commandEric Wong2007-02-231-3/+20
| | | | | | | | | | | Similar in spirit to the recent dcommit change, we now look at 'HEAD' by default to look for a GIT_SVN_ID so the user won't have to pass -i <GIT_SVN_ID> argument. We are also more tolerant of of people passing bare remote names as a result (just $GIT_SVN_ID without the -i) Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: include merges when calling rev-list for decommitEric Wong2007-02-231-1/+1
| | | | | | | | Merge commits can be created when following certain parents, (most notably 'R' cases) and we definitely don't want to exclude them. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: make dcommit usable for glob usersEric Wong2007-02-231-22/+51
| | | | | | | | | | | | | | | | | | | | * dcommit no longer requires the correct -i/GIT_SVN_ID option passed to it. Since you're committing from HEAD (or another commit that is a parent of HEAD), you'll be able to find a commit with metadata information containing the SVN URL that your HEAD was descended from anyways. * I don't think dcommit ever worked for people using the noMetadata option; so I don't think relying on metadata is an issue. * useSvmProps users shouldn't commit to SVN::Mirror created repositories anyways, right? * Users of globbing should automatically be able to commit to paths that are not explicitly set in .git/config Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: handle multi-init without --trunk, UseSvmProps fixesEric Wong2007-02-231-33/+83
| | | | | | | | | | | | | | | | multi-init did not write a svn-remote.<remote>.url config entry without a --trunk argument. Also, The svm:mirror property is used by SVN::Mirror to track the path of the repository that we are mirroring. We need to append that to the source (which is (presumably) just the URL of the repository root). Lastly, we now look harder for svm:(source|mirror|uuid) properties in sub and parent directories. Since our relative path could be tweaked. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: write the highest maxRex out for branches and tagsEric Wong2007-02-231-0/+4
| | | | | | | | | Even if nothing touched paths we care about in a fetch; increment the maxRev like we do with rev_db since we don't like having to run get_log on revisions we've seen before. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: use separate, per-repository .rev_db filesEric Wong2007-02-231-50/+123
| | | | | | | | | | | | | | We need a separate .rev_db file for each repository we're tracking. This allows us to track the same logical path off multiple mirrors. We preserve a symlink to the old .rev_db (no-UUID) if we're (auto-)migrating from an old version to preserve backwards compatibility. Also, get rid of the uuid() wrapper since we cache UUID in our private config, and the SVN::Ra::get_uuid() function memoizes the return value per-connection. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: extra safety for noMetadata and useSvmProps usersEric Wong2007-02-231-7/+22
| | | | | | | | | | | | | Make sure we flush our userspace buffers and and fsync(2) .rev_db information to disk if we use these options because we really don't want to lose this information. Also, disallow --use-svm-props and --no-metadata from the command-line because history will be inconsistent if they're only used occasionally. If a user wants to use these options, they must be set in the config so they're always on. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: use private $GIT_DIR/svn/config file moreEric Wong2007-02-231-32/+21
| | | | | | | Switch max_rev storage over to using it for globbing branches and tags. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: add support for per-[svn-remote "..."] optionsEric Wong2007-02-231-9/+35
| | | | | | | | | | | | | | | Available options are currently: svn-remote.<remote>.{noMetadata,useSvmProps,followParent} These boolean switches will override options set globally in [svn], and even override options set on the command-line (this should probably change in the future, however). Note that the noMetadata and useSvmProps options conflict. It's both technically and logically impossible to use them together. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: add support for SVN::Mirror/svk using revprops for metadataEric Wong2007-02-231-10/+105
| | | | | | | | | | | | | | | | | | | | Pass --use-svm-props or set the svn.usesvmprops key with git-config to enable using properties set by SVN::Mirror when it mirrored the upstream URL. This is heavily based on work from Sam Vilain: > From: Sam Vilain <sam@vilain.net> > Date: Sun, 11 Feb 2007 12:34:45 +1300 > Subject: [PATCH] git-svn: re-map repository URLs and UUIDs on SVK mirror paths > > If an SVN revision has a property, "svm:headrev", it is likely that > the revision was created by SVN::Mirror (a part of SVK).

* git-svn: remove optimized commit stuff for set-treeEric Wong2007-02-231-10/+2
| | | | | | | | I may resurrect it for dcommit at some point, but nobody really uses set-tree anymore and I don't feel like introducing more complexity into the code at this point. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: correctly handle globs with a right-hand-side path componentEric Wong2007-02-231-24/+60
| | | | | | | | | | | | | | | | | | Several bugs were found and fixed while getting this to work: * Remember the 'R'(eplace) case of actions and treat it like we would an 'A'(dd) case. * Fix a small case of follow-parent missing a parent if a subdirectory was modified in the revision where the parent was copied. * dirents returned by get_dir sometimes expire if the data structure is too big and the pool is destroyed, so we cache get_dir (along with check_path and get_revprops) temporarily along with its pool.

* git-svn: fix buggy regular expression usage in several placesEric Wong2007-02-231-13/+19
| | | | | | | | | | | | I incorrectly used $path/? and $path/* to strip off leading directories, but places where $path = 'branches/0.17' would incorrectly strip changes to 'branches/0.17.1' as well. For globs, we require that our '*' is its own path component (surrounded by '/' or nothing). Enforce this when --prefix= is passed to us, too. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: enable follow-parent functionality by defaultEric Wong2007-02-231-2/+2
| | | | | | | | --no-follow-parent disables and reverts it back to the old default behavior of not following parents (if you don't care for full history). Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: remove some noisy debugging messagesEric Wong2007-02-231-19/+2
| | | | | | | | | | | | We don't need them anymore, all the rough points of the --follow-parent implementation have been worked out. The only improvement in the future will probably be --follow-parent-harder, which will track subdirectories and follow individual file history (so annotate/blame can be complete); but that is still a ways off. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: remove check_path calls before calling do_updateEric Wong2007-02-231-8/+3
| | | | | | | | | | | These checks were needed before git-svn got smarter about match_paths() and using path information returned by get_log(). We also have extra checking against fetching revisions out-of-order these days; so we don't have to worry about that as much. We also check for tree deletions in match_paths() and skip those as well. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: --follow-parent tracks multi-parent pathsEric Wong2007-02-231-3/+11
| | | | | | | | | | | We can have a branch that was deleted, then re-added under the same name but copied from another path, in which case we'll have multiple parents (we don't want to break the original ref, nor lose copypath info). Add a test for this, too, of course. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: implement auto-discovery of branches/tagsEric Wong2007-02-231-28/+120
| | | | | | | | | | | | | | | | | | | This is similar to the way git proper handles refs, except we use the keys 'branches' and 'tags' to distinguish when we want to use wildcards. The left-hand side of the ':' contains the remote path, and must have one asterisk ('*') in it for the branch name. The asterisk may be in any component of the path as long as is it on its own directory level. The right-hand side contains the refname and must have the asterisk as the last path component. branches = branches/*:refs/remotes/* tags = tags/*:refs/remotes/tags/* Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: run get_log() on a sub-directory if possibleEric Wong2007-02-231-7/+48
| | | | | | | This is an optimization that should conserve network bandwidth on certain repositories and configurations. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: reintroduce using a single get_log() to fetchEric Wong2007-02-231-54/+49
| | | | | | | We'll need to rely on path matching to handle wildcard support for branches and tags. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: prepare multi-init for wildcard supportEric Wong2007-02-231-7/+117
| | | | | | | Update the tests since we no longer write so many things to the config. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: just name the default svn-remote "svn" instead of "git-svn"Eric Wong2007-02-231-1/+1
| | | | | | | It can be confusing and redundant, since historically the default remote ref (not remote itself) has been "git-svn", too. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: avoid extra get_log calls when refspecs are added for fetchingEric Wong2007-02-231-1/+6
| | | | | | | | Since fetch_loop_common starts from the lowest revision number in a group of Git::SVN objects; we want to avoid refetching get_log for current users for things we've already cut it. Signed-off-by: Eric Wong <normalperson@yhbt.net>
* git-svn: get rid of revisions_eq check for --follow-parentEric Wong2007-02-231-11/+1
| | | | | | | | This was originally needed before we used the delta fetcher and had a less-clean follow-parent implementation that could leave holes in the history. Signed-off-by: Eric Wong <normalperson@yhbt.net>
