FS#12320 - need substitute to /.rockbox/skin_buffer_size.txt

Since version r30718 “Revert r30599 “Check for the magic file “/.rockbox/skin_buffer_size.txt” my WPS is not loading again. With the last changes to buflib my WPS didn’t work until I’ve used “/.rockbox/skin_buffer_size.txt” to load my WPS that is 47.2KB in size (”system > rockbox info > skin buffer usage”).
Is there a way to fit my WPS on the buffer? (My theme is BigInfoAA on the Themes page)
At the moment, I switch it back to r30717.

proper fix should be in svn in the next day or two

Can you try this patch? It optimizes one often allocated struct for size.

That saves barely 2K on e200 cabbie (run the two attached .log files through lib/skin_parser/skin_buffer_debug.pl). i.e a completely pointless patch. The *only* correct fix is to figure out how to get that struct onto buflib, all other patches are a waste of time.

edit: the next biggest allocation is apps/gui/skin_engine/skin_parser.c:1851 but even that is barely 2k (on cabbie), and this is an easier one to convert to buflib but even that is pointless

I've tried it and it didn't work for me. :'(

How do you use skin_buffer_debug.pl, or how do you generate the logs?

jdgordon commented on 2011-10-09 10:52

skin_buffer_debug.pl file.log | sort -k2 -nr
enable the debug line in libs/skin_engine/skin_buffer.h

kugel. commented on 2011-10-09 11:14

Okay, making the structs smaller obviously doesn't help since the skin buffer takes their size into account. MAX_WPS_TOKEN can be increased according to the space saved by the smaller structs.

kugel. commented on 2011-10-09 11:19

This does bump MAX_WPS_TOKEN a bit, for the space changed by decreasing the struct sizes. Makes BigInfoAA fit on the 64bit sim

How exactly is that better than the change you reverted? It is still an arbitrary limit. OK, BigInfoAA fits but some other skin wont. The only sane thing to do is put skin_element on buflib or make the buffer size configurable

kugel. commented on 2011-10-09 11:36

It's a fix to a regression introduced by the skin-engine-to-buflib changes. Without extra cost, and without introducing questionable new features.

sadur commented on 2011-10-10 06:01

This afternoon I'll give it a try.
Thanks.

sadur commented on 2011-10-10 15:05

It works for me. Is this a definitive solution, or is there anything I could try/do to help find a better solution?

jdgordon commented on 2011-10-16 22:43

The commit is a stop gap solution but not a real fix. This task shouldnt have been closed.
