Sometimes the log is written with one less file than analyzed

[vicmarto]

Seems dr14_t.meter has unreliable results in my system when NOT using "--disable_multithread".

When analyzing a folder with some wav files, and NOT using "--disable_multithread", dr14_t.meter sometimes just skips the last file when writing the log. But this only happens sometimes, not always.

Some log:

$ dr14_tmeter --outdir '/usr/home/vicmarto/@dr14_tmeter/3/1988 To the Power of Three/OK' --dr_database --skip_version_check '/usr/home/vicmarto/@dr14_tmeter/3/1988 To the Power of Three/dr14/'

/usr/home/vicmarto/@dr14_tmeter/3/1988 To the Power of Three/dr14

Note the 8th file, it was analyzed, but is not in the log.

I wrote a little script to analyze this same 8 wav files 245 times, and 54 times the log was incorrect (with only 7 files). This is a failure of about the 22%. Running the same test but with the "--disable_multithread" option resulted in zero fails.

This is FreeBSD 11.3-RELEASE-p7, using a Jail. I'm not sure if this is reproducible in another system.

Thanks, and sorry for my broken English.

I'm seeing exactly the same on a fairly regular basis. I'd say incidence is in line with that you've reported. Linux X64.

@simon-r, are you still maintaining this codebase?
