From: Reuben Thomas <rrt <at> sc3d.org> To: 8714 <at> debbugs.gnu.org Subject: bug#8714: 23.3.50; Flymake kills my computer on mass revert Date: Sat, 21 May 2011 23:12:50 +0100
If I have a lot of buffers open with flymake switched on, and I git checkout a different branch of a project, causing the buffers to auto-revert (because I have auto-revert switched on) then my computer is slowed down massively by having a new make process started for each and every buffer. Is it reasonable to suggest that flymake should at the very most try to recheck buffers that are actually visible, and arguably only the buffer being edited; if visible buffers, then maybe an additional safeguard of a maximum number of processes to start would be a good idea. If you’re wondering why the process was so onerous, it’s that after checking out a different branch (not an uncommon operation, I believe), make realised that it had to re-run automake, so I had about 30 processes trying to run automake simultaneously, which turns out to be quite hard work even for a reasonably powerful (2GHz/2Gb) machine.
