Description MontyHimself 2016-11-06 14:32:54 GMT
Whenever I try to encode a single FLAC file with embedded cue sheet to Vorbis, the locally cached CDDB entries in ~/.cddb are not queried. They are certainly there, though, I checked manually. When I rip a CD to a single FLAC file, it works flawlessly (like when I want to rip a CD that I have ripped before), but when I then try to convert this file to individual Vorbis files, the CDDB entries are not recognized anymore. The weird thing about this is that it works when I use one of the older FLAC files that I ripped in the past on Ubuntu with abcde v2.7.1. I recently switched to Fedora and only the newer ones which I ripped with abcde v2.7.2 on Fedora have this issue.

This leads me to believe that the issue lies within the ripped FLAC files themselves. One thing that changed when switching from Ubuntu to Fedora and with it from abcde v2.7.1 to v2.7.2 is that I now have to use abcde's internal implementation of mkcue, since there is no package for mkcue in Fedora. Maybe this is the source of the problem.

Here is the command line output:

$ abcde -d The\ Reprise\ Collection\ \[Disc\ 4\].flac
[WARNING] switching to flac CDROMREADERSYNTAX...

Which entry would you like abcde to use (0 for none)? [0-3]:

I would expect to be asked if I want to use the locally cached CDDB entry for this CD, but as you can see this doesn't happen.

Here is my abcde.conf for converting to Vorbis:

Here is the one for ripping CDs to FLAC files (the only thing I changed when switching to Fedora was replacing mkcue with abcde.mkcue):

The cue sheets for the older FLAC files don't seem to contain any important additional information.

I've stumbled in this problem, which eventually led me to open issue 47: https://abcde.einval.com/bugzilla/show_bug.cgi?id=47

I found that the problem was in the cue files generated with the single-file flac rip.
When ripping from cd, the discid used to query CDDB is generated with cd-discid.
When you are ripping Ogg Vorbis files from the resulting flac, the discid is instead generated from the cue file.
I noticed that the two discids were different, which of course caused a cache-miss.

I tried using MKCUE="mkcue" and MKCUE="abcde.mkcue" in the configuration file, but I didn't notice any difference.

Then, reading in the documentation and the code, I noticed that abcde.mkcue() accepts a --wholedisk option, which basically determines how the cue file is written. So I set MKCUEOPTS="--wholedisk" in the configuration file, and noticed that it made no difference.

Further digging led me to open the aforementioned issue and submit a patch. Applying the patch fixed the problem and the cache-miss, at least for me.

I've just applied Nino's patch from Bug 47 in git. Could you test and confirm if this fixes your bug too please?
