Should have an option (configfile) to be more tolerant to errors #1642

Open tstyopin opened 4 years ago

tstyopin commented 4 years ago

Hello! I have an ARM boards with attached hard drives, which runs Nextcloud. Boards are rather slow, so nothing on them works with 100% reliability. Please add an option to ignore errors on file transmission (timeouts especially), so desktop client can download some other files, rather that begin sync from very beginning. Also, there is no option to limit simultaneous downloads (setting env variable seems don't work on Windows) in interface, can you add this to config file or interface directly?

Expected behaviour

If there is time-out on one file while other files exist in download queue desktop client should try to download next file from queue instead of failing whole sync process There should be an configurable option in interface or config file to limit simultaneous downloads (today i saw 43 threads, which literally hang my board by swap)

Actual behaviour

Sync process failing, when one thread failed, no other files are tried to downloading There is no configurable option to limit simultaneous downloads

Steps to reproduce

  1. Have tiny small ARM boards
  2. Have Nextcloud up and running on them (i have mysql and nginx+php-fpm on separate boards)
  3. Try to download 20k-40k files in one run in fast home network (on slow networks not failing so much)

Option --max-sync-retries seems not work, as no retries are made (dont saw in logfile) Option --unsyncedfolders has no documentation or examples, so i cant sync only one folder
