Fecthing revisions is very slow on large repositories. This seems to be a hg issue, its just as slow from the command line. Currently we have a limit of 100 revisions to fetch. We could reduce this to 10 and add in a few options "Next 20..." "Next 50..." "All..." to the combo to optionally allow a user to fetch more revisions. This would speed up the common use case, when you are just dealing with the last few revisions.
Changed how Export Diff works - now comes up and fetches 7 revisions by default (above 7 get big performance hit), but gives users options to: "Fetch up to 20 revisions..." "Fetch up to 50 revisions..." "Fetch up to All revisions..." On my Sony dual core x86 1.8GHz with 2 Gig RAM, to get the revisions its taking against hg.netbeans.org/main: 5-7 revisions: 15 sec 8-20 revisions: 40 sec 25-50 revisions: 100 sec Will do the same for the other Dialogs that fetch revisions: Backup, Strip, Revert and Update changeset: 72792:e77829cdd2b7 tag: tip user: jrice@netbeans.org date: Tue Mar 11 21:23:09 2008 +0000 summary: #129799: Fetching Revisions for Export is slow on large repos - reduce number fetched and added options to get more

Added changes to limit revisions fetched in Update, Revert, Strip and Backout. Also came across issue when you have multiple heads for these dialogs. As context was not being passed, the list of revs was following one branch only and not listing all revs as it should. So changed all the dialogs including Export to pass in appropriate context so they do the right thing. changeset: 72884:59101cfe5108 user: jrice@netbeans.org date: Wed Mar 12 12:15:29 2008 +0000 summary: #129799: Fetching Revisions for Export is slow on large repos - adding similar support to Backout, Strip, Revert and Update changeset: 72885:baca7c59498c user: jrice@netbeans.org date: Wed Mar 12 15:03:10 2008 +0000 summary: #129799: Fetching Revisions for Export is slow on large repos - adding similar support to Backout, Strip, Revert and Update
