Subject Revisions not in chronological order
Date Fri, 29 Oct 2010 14:42:26 GMT
Hi,

My repository is made up of a load of folder loaded from cvs2svn dumps.
These were loaded individually and have overlapping date ranges.
When doing an "svn load" it looks like SVN assigns each commit to the
next revision, regardless of the date the commit occurred.

As a result the rage of revisions created for each of the loads have
overlapping dates and the revisions of the repository are not chronological. 

E.g.

C:\Windows\system32>svn log -v -r 2000 https://svn/svn/repo/
------------------------------------------------------------------------
r2000 | <username> | 2006-07-13 11:41:27 +0100 (Thu, 13 Jul 2006) | 2 lines
Changed paths:
   M /Folder1/file1

C:\Windows\system32>svn log -v -r 20000 https://svn/svn/repo/
------------------------------------------------------------------------
r20000 | <username> | 2003-08-19 04:30:07 +0100 (Tue, 19 Aug 2003) | 1 line
Changed paths:
   A /Folder2/file1

C:\Windows\system32>svn log -v -r 21000 https://svn/svn/repo/
------------------------------------------------------------------------
r21000 | <username> | 2006-05-19 11:55:33 +0100 (Fri, 19 May 2006) | 1 line
Changed paths:
   A /Folder2/file2

This causes problems for "svn log" and "svn cat" when attempting to get
revisions at a particular date for a folder. SVN will find the lowest numbered
revision for that date, regardless of whether the folder exists for that
revision. e.g.


C:\Windows\system32>svn log -r {2010-07-11} https://svn/svn/repo/Folder3
svn: Unable to find repository location for 'https://svn/svn/repo/Folder3' in revision 63506


However there are revisions for that date...


C:\Windows\system32>svn log -r 114691 https://svn/svn/repo/Folder3
------------------------------------------------------------------------
r114691 | <username> | 2010-07-11 11:12:14 +0100 (Sun, 11 Jul 2010) | 2 lines

I've tried "svndumptool check" to check a dump of the entire repository, but it comes back
ok.
An "svn load" of the dump seems to keep the same revision numbers and dates.

Is there a way of reorganising the repository to have all revisions in 
chronological order?
How can I avoid this happening in the future?
Or is there some other way for getting round this?


Thanks
Chris
