Public bug reported:
This is regarding /usr/share/zsh/vendor-completions/_mpv which is in the
package "mpv".
If you make a dirname with lots of dots and open bracket and close
bracket, like:
/tmp/XXX.X.X.X.X.X.XX.X.X.X.X.X.X.X.X.X.X.X.X.X.X.X.X.XX-X.X.X.X.X.X.X[XXXXX]
Put some media files inside, and try to autocomplete with:
mpv
/tmp/XXX.X.X.X.X.X.XX.X.X.X.X.X.X.X.X.X.X.X.X.X.X.X.X.XX-X.X.X.X.X.X.X\[XXXXX\]/<TAB>
zsh gets into a loop that depending on the disk might take dozens of
minutes or hours to complete. In a network file system it might
practically hangs forever. Using zsh -xv to check the completion I see
that the completion has increasingly bigger hangs after this part
repeats:
+compadd:9>
PREFIX='(#a20)/tmp/XXX.X.X.X.X.X.XX.X.X.X.X.X.X.X.X.X.X.X.X.X.X.X.X.XX-X.X.X.X.X.X.X\[XXXXX\]/'
+compadd:12> (( 1 && 5 ))
+compadd:13> _correct_expl[_correct_group]=-J
+compadd:15> compadd -J corrections -X '- corrections - (errors 20})' -S '' -J
urls -X '- URL -' cdda:// rtmp:// rtsp:// https:// mms:// mmst:// mmshttp://

dvd:// dvdnav:// file:// bd:// br:// bluray:// bdnav:// brnav:// bluraynav://
memory:// hex:// null:// mf:// edl:// rar:// file:// fd:// fdclose://
The delay to get to the next part seems to increase exponentially. I am
attaching an excerpt of the zsh -xv run. A similar symptom happens with
mplayer but it does not take as long - a couple minutes instead of more
than half an hour. After it finishes, it doesn't match any media file,
although there are mkv files in there: No matches for: `video file',
`media file', `URL', `URL prefix', or `corrections'
This does not seem to occur with any other programs, media or otherwise.
For media players I tried ffmpeg kmplayer totem xine avconv avplay.
