Revision 63129 is not valid on case folding filesystems. In particular, this horribly breaks using hg-svn to make a local mirror of the Python repository:
That would be a bug in hg-svn, right? Yes, the revision is not valid on case-folding systems - but why should that break hg-svn? The tool should be able to represent such stuff in its repository (whatever concept of repository hg may have); it should then only fail if you also want to check out that specific revision.
Absolutely it's a bug in hgsvn (which is a converter for svn -> hg, this isn't a bug in hg), but it's a design issue (hgsvn works by checking out each revision in turn and checking it into hg) triggered by having a svn revision which cannot be represented on a case-folsing system.
There is no way to remove this revision from the repository now (other than a full dump|filter|load cycle, which I would rather want to avoid).
OK, there's no way this is justified for such an obscure issue - all I'm really asking is that people remember case-folding systems when making changes like this.
I know it's a rare situation, but can people PLEASE be careful not to introduce case issues like this - they pollute history for ever (I still hit problems with some of the case funkiness in svn from the early 1990's!!!)
Subversion's first release was in October 2000; it wasn't self-hosting until 2001 :-)
I assume it's pre-svn history, converted from CVS. Or I'm misreading something. Whatever, it's from a long time ago :-) Paul.
