RE: [BUG] svnlook diff infinite loop

                Hi,

I tried to reproduce your problem for debugging.

I did a:

$ svn –version

svn, version 1.8.9-SlikSvn-1.8.9-X64 (SlikSvn/1.8.9) X64

   compiled May 8 2014, 20:00:31 on x86_64-microsoft-windows6.2.9200

<snip>

$ svnadmin create svnlook-loop

$ svnadmin load svnlook-loop < svnlook_diff_infinite_loop.dump

<<< Started new transaction, based on original revision 1

     * adding path : xyz ... done.

------- Committed revision 1 >>>

<<< Started new transaction, based on original revision 2

     * editing path : xyz ... done.

------- Committed revision 2 >>>

<<< Started new transaction, based on original revision 3

     * editing path : xyz ... done.

------- Committed revision 3 >>>

$ svnlook diff svnlook-loop

Index: xyz

===================================================================

--- xyz 2014-05-29 13:37:20 UTC (rev 2)

+++ xyz 2014-05-29 13:37:32 UTC (rev 3)

Property changes on: xyz

___________________________________________________________________

/abc/2.1:6

-/abc/2.2:7

\ No newline at end of property

+/abc/2.2:7,9

\ No newline at end of property

Can you explain what is different for you than in this scenario, as this certainly doesn’t reproduce your problem

Subject: [BUG] svnlook diff infinite loop

svnlook diff hangs on an infinite loop when it encounters certain svn:mergeinfo.

This happens ONLY on Windows 64-bit svn 1.8.x or later client.

I was able to trace the flow of code all the way to:

subversion/svnlook/svnlook.c:display_prop_diffs

Inside here, there is a call to:

subversion/libsvn_diff/util.c:svn_diff__display_prop_diffs

Which doesn't seem to get executed at all.

I have no experience debugging C code on Windows, and hence the speculation.

I have with me the smallest possible subset of data that will reproduce this issue.

Load the attached dumpfile and run svnlook diff -r3 /path/to/repo with a 1.8.x or later binary on a Windows 64-bit machine, and it WILL hang.

I really hope someone with debugging skills on Windows can help me out here.

Regards,

Arwin Arni
