Faster revision graphs
by Shawn Castrianni
::
Rate this Message:
I realize that SVN has a significant architecture flaw (in my opinon) to only store Copy-From links instead of both Copy-From and Copy-To links. Therefore, any revision graph command must play back the entire transaction history looking for branch points to properly draw the graph. I also realize that you keep a cache of the full transaction history to speed up this revision graph, branch point search. However, the speed of generating these revision graphs in SmartSVN is nothing like SmartCVS where the CVS architecture is more efficient in this area. I was curious what you actually store in the transaction history cache. I would think that if you generated Copy-To links inside your private SmartSVN transaction history cache, that you could then generate revision graphs very quickly. I am assuming that you do NOT generate these Copy-To links making your revision graphs still a little slow.
So I was wondering, until SVN fixes its architecture with Copy-To links, can you do anything more with SmartSVN to improve the revision graph generation? Can you scan the transaction history after you have cached it and generate Copy-To links as part of the cache? --- Shawn Castrianni ---------------------------------------------------------------------- This e-mail, including any attached files, may contain confidential and privileged information for the sole use of the intended recipient.

Wonderful!
By the way, none of my log cache was migrated when I ran SmartSVN 6 for the first time. I can still see it sitting in my 5’s log-cache folder while my 6’s log-cache folder is empty. Do I have to rebuild my log-cache when upgrading from 5->6? --- Shawn Castrianni From: smartsvn@...

SmartSVN's Log Cache format has changed since the first 6 beta version, so it should have reported that Log Caches have to be rebuilt.

No, everything is standard. When I started SmartSVN6 for the first time, it took about 2 minutes before the splash screen came up. While waiting, I checked my user directory and saw that it was copying my repository and project profiles over from 5 directory to new 6 directory. Splash screen came up with no warning about rebuilding log caches. No problem I will rebuild them.
