 Description  « Hide
We have a fairly large subversion repository (~32k revisions) and when we use the "Integrate Project' feature to merge changes from one branch to another, the "..." option takes a very long time to fetch the svn log. When not on the same LAN as the svn server, this takes well over a minute (even @ near T1 speeds). What's worse is that if you press it a second time (for Source 2) it takes another minute or so. I see two problems:
  • It looks like it's fetching the entire svn log for the repository. It seems to me that it makes sense to either limit it to a number of entries (the last 100 entries) or duration's worth of entires (the last month's worth of entires). This would handle 95% of the normal use cases and make this feature much more performant.
  • The log should be cached so that if "..." is selected a second time while the "Integrate Project" dialog is on the screen, the log is not fetched from the server.

I think these two changes would go a long way in improving the Integrate Project feature.
