Quick fixes: the binary tape player now considers talk to the sleep observer only if motor control changes. The Amstrad CPC no longer attempts to use the component argument to identify the caller, since this

Improved logic for detecting when all sense has been derived from a track to spot any repeated track, not necessarily the first one. That avoids sectors that run over the index hold and obscure the first throwing things.

Added an easy way for disk controllers to clamp termination of written data exactly to the index hole.
...
This commit also temporarily provides a whole load of extra logging and minor logic improvements from the 8272. I'm mid-flow on finding a particularly vicious error in its handling of writing; wait for the pull request. But, at least: now waits for the first part of a post-ID gap before writing data, and attempts partially to handle appearance of the index hole during writing a track. More work to do on that though.
2017-08-15 16:05:10 -04:00
Thomas Harte
9541a2a5f0
Corrections: seek_to
now takes the segment_start_time
into account, correcting a windowing error where segments overlay other segments. Also added some asserts while bug hunting, and corrected the steps taken when inserting a longer-than-a-track segment so that each is correctly windowed.
2017-08-15 15:54:09 -04:00
Thomas Harte

Flagged as not read-only, at least for now, to allow 8272 writing tests definitively to function.

Strung together a very basic version of 8272 write [/deleted] data. Lots of cases as-yet unhandled.

Entrusted further status to drives; also adjusted them to report read only if diskless, which I now believe to be correct.

Upped C++ standard to C++14 and added an #if that's intended to use the built-in std::gcd when compiled on C++17 or better. Fixed for new signedness warnings resulting for taking the step to C++14.

Adjusted to avoid calls to ::greatest_common_divisor(numerator % denominator, denominator)
unless necessary.

Switched to populating the sector cache with everything in a track the first time anything on that track is requested. That avoids the problem whereby each request of a non-existent sector costs two spins.

Sector
size is now reported, and CRC failures are merely indicated, not cause for a sector to be thrown away.

Updated the SSD file format container to specify sector sizes, now that it's no longer implicit.

Expands the [M]FM encoder to respect some new Sector flags: it will now wilfully make CRC errors, omit data, include data that is different than the ID's declared length, write deleted data, and can be commanded as to header/data gaps and what should be within them. All based around expanding towards the needs for reproduction of the CPC's .DSK file format.

Added an attempt to deal with 16-bit allocation units, and to ensure middle-of-file holes are respected.

Killed logic_extents_per_physical, since I don't know how to handle it, and instituted tracks, to allow a decision about short versus long allocation units.

Threw a sector cache into my MFM parser, in an attempt to cut down analysis costs. Also made it aware of multiple heads.

Started working on a CPC-oriented analyser; for now I just want to be able to make a good guess at the appropriate file to load from a disk. As it turns out, the CPC simply adopts the CP/M format, so a generic parser is appropriate. This is its beginning.

Added a 'ready' getter to Drive
, formally to let the drive take ownership of that test.

Prevented the 8272 from overreading ID fields (and, by doing so, overrunning its internal buffer). Exposed the MFMController's CRC generator for inspection.

Adapted slightly, to retain the ability to advertise an incorrect size, to adjust the confusion I've created by having two different types of thing both called new_sector, and to print a warning when ignoring error flags.

Fixed search for track start position with extended disks: it's no longer an infinite loop. So that's a pretty good performance improvement.

Fixed: rewind the file to check for 'EXTENDED' if 'MV - CPC' failed.
