Hi all,
I am in the process of writing a script which would check for the mergeinfo
of a path and see if the path is present through all the revisions mentioned
in the mergeinfo property. If the path was not found for any revision range
then the script would suggest(as of now) a better way to propget the
mergeinfo property or even propset the correct mergeinfo property (not yet
decided on this though).
In the process of testing the script against our "trunk" source I could see
some bogus mergeinfo properties when there is a break in the history.
Here is an example:
The mergeinfo for
http://svn.apache.org/repos/asf/subversion/branches/tree-conflicts is
868291-873154
but if I do location_segments for this range of revision for the above path,
I get
r868291 - r872329: subversion/branches/tree-conflicts
r872330 - r872524: null
r872525 - r873154: subversion/branches/tree-conflicts
After looking at log -v, it was clear that the
"subversion/branches/tree-conflicts" was deleted and copied (i.e replaced).
Logically the branch "tree-conflicts" was not present at all at the revision
range r872330-872524.
This brings a breakage of history. But the mergeinfo is not clear enough to
show this change.
I tested the same case with the 1.6.12, 1.6.17 and the trunk builds. The
(possible) bug is seen in all the three cases.
I have not yet filed any bug so far. Please share your thoughts.
Hi Prabhu,
There are a few known issues where mergeinfo can be created which
describes non-existent merge sources:
One still open:
http://subversion.tigris.org/issues/show_bug.cgi?id=3867
Two which have been fixed:
http://subversion.tigris.org/issues/show_bug.cgi?id=3432
http://subversion.tigris.org/issues/show_bug.cgi?id=3669
I might be forgetting a couple others, but those are the ones that come to mind.
You might want to check if one of those three is the culprit here.
Thanks Paul, this case is different from all the above three cases though it
looked
quite similar to the case,
http://subversion.tigris.org/issues/show_bug.cgi?id=3669
Here there seems to be no sign of inheritance of mergeinfo as is the case in
"3669" and no sign of
copyfrom as is the case in "3432".
Regards,
Prabhu
