Query subversion for all files that have a certain property

[Georg Viehöver <vi...@sigma-c.de>]

Hi all,

Coming from the ClearCase world, I wonder if it is possible to query a subversion repository for all files that have a certain property (it is a one line command that is fairly efficient even for 10000nds of files in ClearCase). The use case that I am thinking about is to query subversion which files have been changed for a certain bug, attaching the bug number as a property to all files that have been changed in the process of fixing the bug.

I think that looking at the changes for a certain transaction is probably not sufficient: One bugfix may be done as a sequence of svn commits. Using some "find snv propget..." might be possible, but is certainly not efficient.

Any ideas? Maybe I am missing some point?

Georg

Ideally, yes; all your fixes go into one commit.  However, things don't always 
go perfectly, so it may take more than one commit to get everything checked 
in and correct.  Or, suppose you have multiple developers supplying a pieces 
to a multi-part fix.  Each developer checks in their components, thus 
multiple checkins per fix.  

This could be controlled by requiring all changes be done on their own branch, 
and then the merge back is identified as the revision of the fix.  But often 
developers will work fixes to multiple bugs into one module at the same time.  
They would have to work the same module on multiple branches, then do 
multiple merges back to the base.

Yes you are.  :-)   Subversion's commits are "packaged" into atomic 
groups already.  If a bugfix touches 14 files, then 'svn commit' will 
create a new global revision, and the bug is said to be "fixed by 
revision N".  At any time, 'svn log -v -rN' will show you the exact 
change (including list of files) that fixed the bug.  So there's no 
need to remember which file-changes fixed a bug -- just remember the 
name of the commit which fixed it.   That's the information you put 
into the issue tracker when you close a bug.

I've used "svn propget -R svn:mime-type", and it seems to be adequately
efficient.   Although I am using it on a WC.  But "svn propget -R (property)
http://root/of/repository" should work and probably only does one round-trip
to the server.
