Custom Track List Is Sorting Alphabetically Only When Fewer Than 1,000 Items

(1/2) > >>

iPodVT:
One of the ways in which I am using tagnavi_custom.config allows me to access various subsets of the tracks in my database based on the directories in which the tracks are located.  Here is a line from my tagnavi_custom.config file for this purpose:

"Track" -> title ? filename ~ "/Rob's iPod" -> title = "fmt_alphanum_title"

I have observed that the resulting list of tracks will sort alphabetically only if there are fewer than 1,000 tracks.  If there are 1,000 or more tracks it does not sort alphabetically.  This does not happen with track lists that are >= 1,000 when derived from the main menu in tagnavi.config:

"Track"    -> title = "fmt_alphanum_title"

Is there a threshold setting somewhere that is causing this?  Or maybe there is a flaw in my above line?

Thanks.

Now I see that when there are 1,000 or more tracks and the track list is not getting sorted alphabetically, Rockbox is seeming to be parsing the subdirectories and listing the tracks in the order in which they are encountered.

It's determined by the "Max Entries in File Browser" setting. Looks like the manual may have to be updated to make that clear.

Be sure to restart after changing the setting before it takes effect.

Thank you very much.  I upped it to the max allowed - 10,000 - and now everything is sorting all the time.

What happens if/when my number of tracks exceeds 10,000?  Can/should the limit setting be allowed to increase beyond that?  I assume there are plenty of Rockbox users with way more tracks than that.

1000 files seems pretty low as a default. Looks like it might be a bit out of date:

--- Code: ---    INT_SETTING(F_BANFROMQS, max_files_in_dir, LANG_MAX_FILES_IN_DIR,
#if MEMORYSIZE > 1
                  1000,
#else
                  200,
#endif
                  "max files in dir", UNIT_INT, 50, 10000, 50,
                  NULL, NULL, NULL),

--- End code ---

Only a handful of low-RAM targets have 2 MB -- everything else is >8 MB, so I'd argue the default limit should be upped quite a bit.

And I don't think there's a problem with increasing the max limit beyond 10,000.
