comment:7 Changed 14 years ago by IMDagger

Last patch is for (c75ebb2ab9b9002bc26741968092d32dc048104d), but branch has trouble with background processes yet. Trouble:

  • copy file in background
  • look at background process list by C-x j

Process has been already done, but still draw in list.

Sorry for bumping old fixed bug, but I experience it with latest available in distro (4.8.7) mc (not checked on trunk version) while I copy files to FTP server in background.

Replying to mva:

Please describe your actions in details: what you do and what you get. What VFS timeout is set up? Is total copy time more than VFS timeout or not?

comment:15 Changed 11 years ago by mva

0) VFS timeout = default = 60s
1) F9->Right panel->FTP Connection->[reqs]->connect
2) open remote subdir,
3) select some directory (.git, for example) in left panel and F5->Background
3a) [don't know, if it is mandatory condition] wait some time. Maybe, more, than 60s.
4) select some another directory in left panel and F5->Background
5) Ta-dam! We get tons of such errors.
