9d555c4a02 Let's try just declining to pump the PLL while in write mode. Added documentation to explain. 2016-12-25 09:19:18 -05:00
Thomas Harte
b57038edc5 Actually, at least index holes will still be receivable while writing, so this wasn't entirely correct. Probably best to leave it in. 2016-12-25 09:16:09 -05:00
Thomas Harte
d606bd7ce5 Added saturation test, fixed code as indicated. 2016-12-24 23:29:37 -05:00
Thomas Harte
09ff9d6a26 Introduced a couple more floating-point conversion tests, fixed errors uncovered. 2016-12-24 23:21:19 -05:00
Thomas Harte
e25195a718 Added a single test for Storage::Time, discovering that I had the wrong sign on float conversions. 2016-12-24 22:59:01 -05:00
Thomas Harte
af69b21033 This is almost complete, except that it doesn't act appropriately if some bits are written but not enough to cover the entire writing period. 2016-12-24 22:51:26 -05:00

f601d796f5 Added documentation. 2016-12-24 22:37:20 -05:00

6e94d0c19f Extended Storage::Disk::Disk to permit write-back of modified tracks, exposed some interface via Storage::Disk::Drive. 2016-12-24 22:11:31 -05:00
Thomas Harte
7f303cfceb Continued the baby steps. 2016-12-24 21:54:43 -05:00

afc6f4129c Withdrew unused tally. 2016-12-24 21:47:57 -05:00
Thomas Harte
1e416d4af0 Withdrew now-unused and never-implemented API from TimedEventLoop, and the redundant track time count from DiskController. 2016-12-24 21:02:10 -05:00
Thomas Harte
bedea48d03 This is a much better way of dealing with being partway into an incoming event. Subject to eliminating overruns, of course. 2016-12-24 20:54:27 -05:00
Thomas Harte
4cb17143ef Messing around trying to lock down timing precisely. Which includes formal initial conditions. 2016-12-24 15:18:46 -05:00
Thomas Harte
4d4852bb78 Ensured that Times start life in their simplest form. 2016-12-24 15:18:03 -05:00
Thomas Harte
4728bda0a2 Added an additional constructor to make sure that regular ints go to the correct place. 2016-12-24 13:27:57 -05:00
Thomas Harte
1e970a9772 Started stepping slowly towards allowing writing on the disk controller, taking the opportunity to introduce self-simplifying behaviour to Storage::Time. 2016-12-24 13:07:23 -05:00

Ensures the Electron's video base address is set properly at construction.

3805e3d17d Ensured base address is set properly at construction. 2016-12-22 22:46:02 -05:00

7028f57336 Simplified a little further. 2016-12-22 18:13:10 -05:00
Thomas Harte
e4e0347638 Attempted to consolidate some of the repetition. 2016-12-21 22:17:00 -05:00
Thomas Harte
72ca06cf8d Added some extra tests, performed some basic tidying. Probably should do more. 2016-12-21 19:54:19 -05:00
Thomas Harte
6a0c7f22ee Added a few more tests. All passing. 2016-12-20 21:46:34 -05:00
Thomas Harte
03579f33f1 Fixed multi-coverage insertion, via an appropriate test. 2016-12-20 21:38:32 -05:00
Thomas Harte
7eca910cc5 Fixed insertion location finding logic, working on the relevant test. 2016-12-20 21:14:05 -05:00
Thomas Harte
c180340474 Added two more passing tests and one that crashes. 2016-12-20 19:25:58 -05:00
Thomas Harte
823ab9bc34 Completed initial non-trivial test, fixing revealed errors. 2016-12-20 19:15:36 -05:00
Thomas Harte
5a508ea0df Attempted properly to cover the exactly-equal starts and ends cases, and to improve meaning. 2016-12-20 18:32:49 -05:00
Thomas Harte
63d861a2f3 Switched from C-in-the-brain manual offset counting to using iterators like an ordinary C++ person. 2016-12-20 18:17:54 -05:00
Thomas Harte
6f17076003 Switched to much more logical shared_ptr ownership of PCMSegmentEventSources by Periods. 2016-12-20 18:13:10 -05:00
Thomas Harte
497b2ae4dd Still by manual inspection: the time for the next event should be provisional until proven acceptable, allowing a proper measurement of time until exiting the period to be taken; also fixed the accumulated period error when seeking back onto the underlying track. 2016-12-20 08:14:16 -05:00
Thomas Harte
6bdde542c5 Edging towards functioning automatic tests, fixed right-period adjustment and slightly decreased searching cost while in the process of adding a test. 2016-12-20 07:52:14 -05:00
Thomas Harte
ec624eaab1 Made an attempt fully to implement PCMPatchedTrack. Which now requires tests. 2016-12-20 07:30:57 -05:00
Thomas Harte
1ef1f6ec69 Attempted to implemnt seek_to and to finish add_segment. Started doing a little of get_next_event but ran out of time for the day. 2016-12-19 21:46:02 -05:00
Thomas Harte
8f937ceac8 Made an attempt to come up with a data structure that actually makes sense (though perhaps this is textbook list rather than vector stuff? I guess it depends on the frequency I expect inserts to occur versus reads) and to implement inserts. Though the Periods aren't yet honoured. 2016-12-19 07:42:43 -05:00
Thomas Harte
1df478d250 Removed dead header file. 2016-12-18 23:04:16 -05:00
Thomas Harte
e081f224b6 Implemented a very basic PCMTrack test, nevertheless revealing an oversight in PCMSegmentEventSource related to improperly counting to the index hole if the final bit is set. Took that as a message that I should comment and document the event source. 2016-12-18 22:53:24 -05:00
Thomas Harte
a6354ebb01 Reimplemented PCMTrack to use PCMSegmentEventSource, eliminating code duplication. 2016-12-18 21:37:05 -05:00
Thomas Harte
f9a5595dad Added seeking tests, correcting such errors as uncovered. 2016-12-18 10:19:24 -05:00
Thomas Harte
3297f6d545 Made an attempt to implement seek_to on PCMSegmentEventSource, taking account of off-by-half counting. 2016-12-17 22:44:33 -05:00
Thomas Harte
3116a2cf4c Realised I was actually testing PCMSegmentEventSource, not PCMSegment; implemented a spread of tests; hence fixed PCMSegmentEventSource. 2016-12-17 21:47:13 -05:00
Thomas Harte
254cc41fd6 Made an attempt to separate and isolate the stuff of creating flux events from a PCMSegment, eventually to factor that out of PCMTrack and make it available also to PCMPatchedTrack. 2016-12-17 21:13:57 -05:00
Thomas Harte
313db75303 Ensured the patchable track owns its underlying track. 2016-12-17 18:17:22 -05:00
Thomas Harte
3017062e89 Maybe TDD is the way to get over my activity block on this thing? Fixed the existing ArrayBuilder tests so that the tests target builds again, added an extremely trivial PCMTrack test, heading towards PCMPatchedTrack tests. 2016-12-17 17:05:49 -05:00
Thomas Harte
f1a08b7ab5 Opted to pass times by reference and added enough to PCMPatchedTrack that it could start being used by the disk controller, albeit that it doesn't work. 2016-12-17 16:26:45 -05:00
Thomas Harte
dc08a23ceb This is going to be a slow walk, I think. This class attempts to be the scratchpad which will hold in-memory track modifications. 2016-12-16 19:20:38 -05:00

63107cd492 Tidied, very slightly. 2016-12-15 19:49:25 -05:00
Thomas Harte
a555c5762a Rearranged code, hopefully into a more logical grouping. 2016-12-15 19:47:04 -05:00
