Now that I am able to run WayPointer with the new 1.6.0 RC2 version, I
could verify that the problem with the SccDiff function appears to be
fixed.

Maybe it works, but I can't verify it because of the issue I had with 1.6.0
RC0.

I.e. my application will hang when used with SVNSCC 1.6.0 RC*, while VS.NET
2005 seems to work OK. Unfortunately the problem was not fixed in RC1
(apparently) or RC2.

We decided to include this fix in the next release candidate. It will be
issued on this week.

Hi, how is it going with the corrected release? The reason I'm asking is
that it was actually one of our customers that noticed this problem, and it
is stopping them from using our product properly.

I can confirm that at this time the SccDiff function did not report that a
local file has been modified, since it compares not the current file on the
local disk, but the file cached in the local index. And I think we should
correct this behavior, as it doesn't meet the SCC API specifications.
Probably, this fix will be included only in next release, but I will try to
provide you with the corrected version within a few days, so you can test
it.

I could add that if I do a SccUncheckout on a changed file, then
SccUncheckout does detect that file is changed and prompts the user if the
changes should be reverted or not. So it's only the SccDiff call that
misbehaves. I tried changing SCC_DIFF.QD_CHECKSUM to SCC_DIFF.QD_CONTENTS,
but that didn't help.

Hi,

I am using SVNSCC 1.5.1.3 with our product WayPointer. We have developed
our own SCC integration and I am having problems with the SccDiff function
call (http://msdn.microsoft.com/en-us/library/bb166501(VS.80).aspx).

The problem is that the function call is returning SCC_OK instead of
SCC_I_FILEDIFFERS when we are checking a file that has been modified. In
other words it fails to detect that the file is different.

Here are two files for which SccDiff fails:

$ svn status m1.wpm
M m1.wpm

$ svn status UCS\ UseCase\ 1.doc
M K UCS UseCase 1.doc

This is a snippet of our code:

SCCRTN result = SccDiff(pvContext, GetCurrentWindowHandler, lpFileName,
SCC_DIFF.QD_CHECKSUM, pvOptions);

switch (result)
{
case SCCRTN.SCC_OK: // The working copy and server version is
identical
return false;
case SCCRTN.SCC_I_FILEDIFFERS: // The working copy differes from the
server version
return true;

Do you have any ideas what could be wrong?
