Split my local SVN archive

Among the years spent at IMT, my SVN repository has become bloated with many things, some of which are not directly related to the work done at Parlab. Before the group closes, I plan to release the software I wrote as open-source, and hopefully with the full SVN history of this software. This requires to split up my bloated repository into smaller units.

I tried to go the 'svnadmin dump' 'svndumpfilter' way, but this did not work due to my abuse usage of cheap copies (thank to the TortoiseSVN copy option). The 'svndumpfilter2' and 'svndumpfilter3' replacements did not work either.

svndumpfilter failed on the first revision with a copy from a non-included path

svndumpfilter2 produced a dumpfile, but displayed various errors from svnlook while running.

The dumpfile could not be exported to a repository.

svndumpilter3 seemd to process everything, but produced many strange beeps during exectution, probably caused by invalid UTF-8 interpretations of binary data (png images and so on). And I failed to find the output dumpfile :-/ Maybe clearer usage explenations from the author would have helped.

Right now, I'm trying to follow the instructions by Cott Lang at Internet Stall, who seems to have encountered the same issues I had with 'svndumpfilter*'

The target repository for sync is created by :

jamesMBpro:tempSVN james$ svnadmin create --fs-type fsfs /tempSVN/FSFS/docREP/

and now, the svnsync preparation, according to http://svnbook.red-bean.com/en/1.5/svn.reposadmin.maint.html#svn.reposadmin.maint.replication

First, change the pre-revprop-change script (done in step 3 in Cott Lang's howto):

jamesMBpro:tempSVN james$ smultron ./FSFS/docREP/hooks/pre-revprop-change

#!/bin/sh   USER="$3"  if [ "$USER" = "syncuser" ]; then exit 0; fi  echo "Only the syncuser user may change revision properties" >&2 exit 1

and then, change the start-commit script:

jamesMBpro:tempSVN james$ smultron ./FSFS/docREP/hooks/start-commit

#!/bin/sh   USER="$2"  if [ "$USER" = "syncuser" ]; then exit 0; fi  echo "Only the syncuser user may commit new revisions" >&2 exit 1

svnsync initialization:

jamesMBpro:tempSVN james$ svnsync initialize file:///tempSVN/FSFS/docREP file:///tempSVN/svnIMTtemp/trunk/doc --sync-username syncuser --sync-password syncpwd

Copied properties for revision 0.

jamesMBpro:tempSVN james$

then, the copying in itself:

jamesMBpro:tempSVN james$ svnsync synchronize file:///tempSVN/FSFS/docREP --sync-username syncuser --sync-password syncpwd

Committed revision 1.

Copied properties for revision 1.

Committed revision 2.

Copied properties for revision 2.

Committed revision 3.

Copied properties for revision 3.

.

.

.

Transmitting file data ...........

Committed revision 2597.

Copied properties for revision 2597.

Transmitting file data .

Committed revision 2598.

Copied properties for revision 2598.

Transmitting file data ...

Committed revision 2599.

Copied properties for revision 2599.

jamesMBpro:tempSVN james$

Now, check the copied repository.

jamesMBpro:~ james$ cd /tempSVN/coTest/

jamesMBpro:coTest james$ mkdir docTest

jamesMBpro:coTest james$ cd docTest/

jamesMBpro:docTest james$ svn checkout file:///tempSVN/FSFS/docREP

A docREP/trunk

A docREP/trunk/doc

.

.

.

A docREP/trunk/doc/JMuWebsite/WebContent/default.php

A docREP/trunk/doc/JMuWebsite/WebContent/video_occlusion.php

Checked out revision 2599.

jamesMBpro:docREP james$

One potential hickup here. The synced repository has the same directory structure as the original repository had (in this case, trailing /trunk/doc/). Nevertheless, the checkout seemed to work, let's see what the log has to say.

jamesMBpro:docTest james$ cd docREP/

jamesMBpro:docREP james$ svn log

Building of one of the most important LaTeX document in this repository (my PhD thesis) worked flawlessly on the first try. Of course, more validation of the robustness of this copy is required, but this is encouraging.
