| ||
| 15:53 | Reworked reltuple again to retain the attribute specs as a constant. This helps when handling relation values and saves a bunch of code regenerating the attributes specs from field names and types. Reworked some of relvalue to demonstrate how it works with the new take on reltuple. More relvalue operations to finish. check-in: d0960ce98d user: andrewm tags: tuple-rework | |

| 16:55 | Merging the correction to the hard fault generated by the timer queue code back onto the trunk. check-in: abc749fb1c user: andrewm tags: trunk | |
| 16:53 | Checkpoint. Continued work on the processing fundamentals chapter. check-in: 7cb7ce6b96 user: andrewm tags: trunk | |
| 16:52 | Correction to the function that sets the expiration time on the system timer comparator register for the timer queue. This code is a modification of the Ambiq HAL code to overcome an errata in the system timer peripheral. The adaptation from the HAL code failed to requesting wrapping addition and consequently would cause an arithmetic overflow if run long enough.

| 14:56 | Checkpoint. Code clean up and work on the lighting application. Tested on actual hardware. Things working as expected. check-in: 1c3396e6c6 user: andrewm tags: trunk | |
| 14:52 | Changed the manner in which timer queue elements were allocated. Previously, a bit set was used and the first unallocated element was selected. This can result in a race condition where the element expires and is freed, but before it can be acted on in the background, another create request arrives. That results in the same element being allocated to the second request. This means the element number is being reused and is not unique in the background. The chosen solution was to cycle through all the elements during allocation and _not_ just take the smallest element number. This gives time for the background to react, althought it does _not_ guarantee the element id number is unique to the background. Considered a number of alternatives like requiring another system call for the background code to "free" the timer queue element. This is more complicated and opens the possibility of loosing timer queue elements. Also considered using a "generation" counter for each element, much like is used for relvar tuple storage. Discarded as too complicated. check-in: c2e62da97c user: andrewm tags: trunk | |
