2011-01-10t9010: svnadmin can fail even if availableLibravatar Jonathan Nieder1-20/+15
If svn is built against one version of SQLite and run against another, libsvn_subr needlessly errors out in operations that need to make a commit. That is clearly not a bug in git but let us consider the ramifications for the test suite. git-svn uses libsvn directly and is probably broken by that bug; it is right for git-svn tests to fail. The vcs-svn lib, on the other hand, does not use libsvn and the test t9010 only uses svn to check its work. This points to two possible improvements: - do not disable most vcs-svn tests if svn is missing. - skip validation rather than failing it when svn fails. Bring about both by putting the svn invocations into a single test that builds a repo to compare the test-svn-fe result against. The test will always pass but only will set the new SVNREPO test prereq if svn succeeds; and validation using that repo gets an SVNREPO prerequisite so it only runs with working svn installations.

2010-12-09t9010 fails when no svn is availableLibravatar Junio C Hamano1-0/+6
Running test t9010 without svn currently errors out for no good reason. The test uses "svnadmin" without checking if svn is available. This was a regression introduced by b0ad24b (t9010 (svn-fe): Eliminate dependency on svn perl bindings, 2010-10-10) when it stopped including ./lib-git-svn.sh that had the safety. This should fix it.

2010-12-07vcs-svn: Allow change nodes for root of tree (/)Libravatar Jonathan Nieder1-0/+55
It is not uncommon for a svn repository to include change records for properties at the top level of the tracked tree: Node-path: Node-kind: dir Node-action: change Prop-delta: true Prop-content-length: 43 Content-length: 43 K 10 svn:ignore V 11 build-area PROPS-END Unfortunately a recent svn-fe change (vcs-svn: More dump format sanity checks, 2010-11-19) causes such nodes to be rejected with the error message fatal: invalid dump: path to be modified is missing The repo_tree module does not keep a dirent for the root of the tree. Add a block to the dump parser to take care of this case. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-11-24vcs-svn: Implement Prop-delta handlingLibravatar David Barr1-2/+100
The rules for what file is used as delta source for each file are not documented in dump-load-format.txt. Luckily, the Apache Software Foundation repository has rich enough examples to figure out most of the rules: Node-action: replace implies the empty property set and empty text as preimage for deltas. Otherwise, if a copyfrom source is given, that node is the preimage for deltas. Lastly, if none of the above applies and the node path exists in the current revision, then that version forms the basis.

2010-11-24vcs-svn: More dump format sanity checksLibravatar Jonathan Nieder1-0/+21
Node-action: change is not appropriate when switching between file and directory or adding a new file. Current svn-fe silently accepts such nodes and the resulting tree has missing files in the "changed when meant to add" case. Node-action: add requires some content (text or directory); there is no such thing as an "intent to add" node in svn dumps. Current svn-fe accepts such contentless adds but produces an invalid fast-import stream that refers to nonexistent mark :0 in response.

2010-11-24vcs-svn: Reject path nodes without Node-actionLibravatar Jonathan Nieder1-0/+20
It would be better to flag such errors and let the import proceed anyway, but for now it is simpler not to worry about recovery from such weird cases. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-11-24vcs-svn: Eliminate node_ctx.srcRev globalLibravatar Jonathan Nieder1-0/+158
The srcRev variable is only used in handle_node(); its purpose is to hold the old mode for a path, to only be used if properties are not being changed. Narrow its scope to make its meaningful lifetime more obvious. No functional change intended. Add some tests as a sanity-check for the simplest case (no renames).

2010-11-24vcs-svn: Allow simple v3 dumps (no deltas yet)Libravatar David Barr1-3/+347
Since the dumpfile version 1 days, the Subversion dump format gained some new fields: - a unique identifier for the repository (version 2 format) - whether the text and properties for a node should be interpreted as deltas - checksums for a delta's preimage - SHA-1 sums as alternatives to the existing MD5 checksums for copy source and the payload (delta). For now what is relevant to us is the Text-delta and Prop-delta fields, since not noticing these causes a dump file to be misinterpreted (see the previous commit).

2010-11-24vcs-svn: Error out for v3 dumpsLibravatar Jonathan Nieder1-22/+37
By ignoring the Text-Delta and Prop-Delta node fields, current svn-fe happily mistakes deltas for full text and instead of cleanly erroring out, it produces a valid but semantically bogus fast-import stream when fed a dump file in the modern "svnadmin dump --deltas" format. Dump file parsers are supposed to ignore header fields they don't understand (to allow for backward-compatible extensions), but they are also supposed to check the SVN-fs-dump-format-version header to prevent misinterpretation of non backward-compatible extensions. Do so. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-11-23t9010 (svn-fe): Eliminate dependency on svn perl bindingsLibravatar Ramkumar Ramachandra1-2/+12
Running test t9010 without the SVN:: perl modules currently errors out, for no good reason. We can make these tests easier to read and run by not using the perl libsvn bindings and instead duplicating only the relevant code from lib-git-svn.sh.

2010-08-14t9010 (svn-fe): use Unix-style path in URILibravatar Jonathan Nieder1-1/+1
Ever since v1.6.3-rc0~101^2~14 (Tests on Windows: $(pwd) must return Windows-style paths, 2009-03-13), there is a subtle difference between $(pwd) and $PWD in tests: the former returns Windows-style paths as might be output by git and the latter Unix-style paths which msys programs tend to prefer. In file:// URIs, Unix-style paths are needed. Before: “svn export” declares it cannot find file://c:/apps/git/git/t/trash directory/simple-svco After: “svn export” successfully finds file:///c/apps/git/git/...

2010-08-14SVN dump parserLibravatar David Barr1-0/+32
svndump parses data that is in SVN dumpfile format produced by `svnadmin dump` with the help of line_buffer and uses repo_tree and fast_export to emit a git fast-import stream. Based roughly on com.hydrografix.svndump 0.92 from the SvnToCCase project at <http://svn2cc.sarovar.org/>, by Stefan Hegny and others.
