more logging and things start to make sense

Multiple locks supported per NativeFile solved.

New issue involves CurrentDir being invoked with a positive lock when system locks are all negative...

nitrologic commented 1 year ago

Still no fix for positive CurrentDir argument.

logging from https://github.com/nitrologic/skid30/blob/main/MyACID500/lha4.log [228]

[write] *** Error on file '' :

which happens way before currentdir, what is it calling,

more logging incoming

nitrologic commented 12 months ago

new issues are likely signal based.

Amiga signals, in you area now?

nitrologic commented 12 months ago

basic signal operations implemented and logged

new task offset for providing root link of 0 means currentdir argument now explained

nitrologic commented 11 months ago

latest curiosity from lha 16 .log:

[exec] findTask <= 80e000 [read32] 80e0b8 [write16] 80e0b8 [write16] 80e0ba [dos] lock t:,fffffffe => 0 [write16] 80e0b8 [write16] 80e0ba

nitrologic commented 11 months ago

Ami style exclusive and shared access improved, current point of value smells like seek quirks.

[dos] seek ffffffe0,fffffff2,BEGINNING => 8000 [dos] read ffffffe0 , 581fc , 8000 => 8000 [exec] copyMem 14 [exec] freemem [exec] freemem [exec] fmt WARNING: Skipping corrupt/extraneous data => WARNING: Skipping corrupt/extraneous data|

nitrologic commented 11 months ago

Setting mmu_read8 back to unsigned byte fixes this seek nonsense.

Now back to

*** Error on file 'format.iff' : |

New trace clock feature added to both system and machine logs.

Combined raw trace of current issue is here:

from latest log, the offset 0xa4 of a task now has magic number to show it up

024ae2 [exec] findTask <= 80e000 024ae5 [read32] 80e0a4,cafeb0b0 024aea [read32] 80e0a4,cafeb0b0 024af5 [exec] findTask <= 80e000
