466c3c34e5 Replace the Error() object with an error() function which takes fmt 
formatspecs, making for much cleaner code. Reformatted everything.

This actually happened in multiple steps but then I corrupted my local
repository and I had to recover from the working tree.

adff739a5d Partial conversion to do automatic scaling of flux based on the disk rotation 
speed. Although, something seems to have broken for 5.25" disks.

d303067deb Massive refactor to work in logical cylinders everywhere. The logical/physical 
mapping is now done at the last stage and should, ideally, be automatic. I'm
sure there are bugs everywhere.

eade2e279e Make the internal disk data structures all const, to allow us to pass them to 
the GUI UI thread safely.

c539debc84 Fix the Amiga decoder, which got broken with the decoder change. Also fix the 
encoder which was always broken (but Amigas apparently didn't care).

0933dc1afa Partially complete rework of all the decoders to avoid seeking inside the 
fluxmap. This requires resetting the FluxDecoder, which loses any pending
state, resulting in bad reads for (some) formats which don't have gaps between
sectors --- the DVK MX is the main victim.

18d90c44dd Rework the flux decoders to add a desync opcode for separating multiple reads 
in a flux stream. Finally add a unit test for the flux decoder.

13deef3416 Plumb the verifier stuff through the rest of the encoders; fix it to actually 
work and not crash, god I hate C++.

458d0f7a1b Another mahoosive refactor: move away from using protos for the disk output in 
favour of pod objects, which allows STL contains. Lots of shared_ptrs
everywhere. Much simpler and more effective code. The reader works with one of
the decoders; still have to do the rest of them and the encoders.

30646ccb07 Fix an Amiga decoder bug where truncated sectors would be considered valid (the 
Amiga checksum algorithm is weak and zero bytes don't contribute to the
checksum).

a401173f6d Teach the Amiga decoder how many sectors to expect on each track. 2020-03-09 12:54:29 +00:00

d25f96dd24 The IBM encoder now works well enough that my USB floppy drive thinks the disk 
is formatted... but has trouble reading sectors above about 1000. Also remember
that encoding MFM needs to keep one bit of state at all times.

d0ed5b32f7 Add support for 528-byte sectors. Adjust the post-index gap to (try?) and fit 
all the data in one revolution. I think my write clock is a bit slow.

792cc88192 The Amiga writer now generates valid flux files --- but it looks like the 
writer's broken (both the Amiga and the Brother have failed).
