A brief status report: The known memory leak caused by a misunderstanding between DEC and Adobe has been fixed. Todd Newman noticed a memory leak inherited from X11R3, in which copies to or from backing store did not free up a (usually quite small) structure it allocated. This affects the Xmfb and Xcfb servers, but should not affect color VAX servers. Unless you do a LOT of copying, this won't lose much space. The only time I've noticed it has been playing a game which used backing store, and as you moved the cursor the game moved a small window around on top of the backing store window. I lost about 8 kbytes per game; normal backing store usage would lose far less. These are the only leaks we've found so far. These fixes should be in the next release of the software. We're still looking for other leaks. - Joel McCormack (decwrl!joel, joel@decwrl.dec.com)

I'd like to commend DEC (and in particular, Chris Kent) for their action regarding these memory. Chris has spent considerable time on tracing memory leaks in xtex, many of with (embarrasingly) occur in my code, not the server (that, plus I was using loads-o-backing store and beating the hell out of DPS contexts). As it stands now, I get display postscript in xtex to use a fairly small amount of memory. I used to use a Sun-3/60, and never had such responsive service from Sun. Go team.

Does DEC have the technology to post Ultrix source patches when they fix things like this, in the tradition of MIT patches to each X release? -- -IAN! (Ian! D. Allen) idallen@watcgl.uwaterloo.ca idallen@watcgl.waterloo.edu [129.97.128.64] Computer Graphics Lab/University of Waterloo/Ontario/Canada

This is not a memory leak, but since we upgraded our DECstation to UWS 2.2, I get the error message 'X Window Manager is confused' whenever I start up DECW$MAIL on our VMS 5.2 VAX client with the UWS 2.2 as a server. It seems to still work OK, though it may be slower than before. We hope to be upgrading the VAXcluster to VMS 5.3 next week which may fix this, but I thought Joel and others might want to know... ++Eric FIelding

DEC *adds value* (?) to the MIT sources, and therefore the idea of posting the patches is highly unlikely. Chnaces are you will find the changes for sample servers in comp.sources.x in the MIT distributed fix files. - Marc =========================================================================== Marc Evans - WB1GRH - evans@decvax.DEC.COM | Synergytics (603)635-8876 Unix/X-window Software Contractor | 21 Hinds Ln, Pelham, NH 03076 ===========================================================================

You should discover that when you upgrade your VMS system(s) to use version 2 of DECwindows that your problem should go away. - Marc =========================================================================== Marc Evans - WB1GRH - evans@decvax.DEC.COM | Synergytics (603)635-8876 Unix/X-window Software Contractor | 21 Hinds Ln, Pelham, NH 03076 ===========================================================================
