Memory snapshots via Insight #46

Closed navnavnav closed 1 year ago

navnavnav commented 1 year ago

Comparing memories at different points during a debug session would be a useful ability to have.

Ideally, we should be able to take a snapshot of the memory. The snapshot should be stored as a file, in Bloom's internal project directory (path/to/project/.bloom), and persisted through debug sessions.
We should also be able to compare a snapshot with another snapshot, or the current memory.
Snapshot diffs should include annotations. Ideally, we should reuse the HexViewerWidget.
Snapshots should be managed via the memory inspection pane, for the particular memory.
I see little need to enable this for program memory. RAM and EEPROM only for now.

More to follow

I've decided to push this back to v0.12.0. I fear that I've already crammed too many changes in v0.11.0. And given the time this will take, excluding it from v0.11.0 means I'll be able to release much sooner than expected.

A lot of the ground work for this was done as part of https://github.com/bloombloombloom/Bloom/issues/51, so I definitely want to get it into v0.12.0.

Quick update on this:

Have made good progress:

Defined memory snapshot data structure
Implemented snapshot management in the memory inspection pane
Created insight worker tasks to capture, save and reload snapshots in between debug sessions

Bloom Insight_189

Selection_230

New Snapshot - RAM_001

There is still much to do before this is ready.

Quick update on this:

I've not had a whole lot of time on Bloom lately. I'm hoping to continue work on this during the weekend. Still not sure when it will be done by - there's a fair bit to do.

Quick update: Almost done with the snapshot viewer window:

Looking to have that window finished by the end of this weekend. Also want to get the 'restore snapshot' function done this weekend.

Then, all that will be left for this ticket is the diff window.

Quick update: Snapshot viewer is complete:

Individual bytes can be restored:

Also, entire snapshots can be restored via the SnapshotManager widget (in the memory inspection pane):

Will be making a start on the snapshot diff window this weekend.

Development work for this is complete. The changes have been merged into develop and will be part of v0.12.0 (due to be released in the next day or two).

Closing this now.
