Thomas Weber bbe7bc035b Make startHats not O(n^2), attempt 2 2021-06-09 22:23:51 -05:00
Thomas Weber cdc962555f Revert "Make startHats not O(n^2)" 
This reverts commit 5659a42b30.

Thomas Weber 5659a42b30 Make startHats not O(n^2) 
For hats with restartExistingThreads=true, a map of target ID +
thread top block ID is maintained in addition to the thread list.
Then, startHats can do a simple lookup instead of iterating over
the entire thread list. Can improve performance in certain
projects that use way too many broadcasts and clones. These
lookups are probably O(1)-ish instead of O(n).

This is not possible for hats with restartExistingThreads=false
due to the extra .status === Thread.STATUS_DONE check.

Thomas Weber 6a8adacb8d Refactor compilation result caching 
Making it less archaic

I mean, giving Object, null, and undefined each different meaning was a bit... questionable

Michael "Z" Goddard 50b55a489b fix stopThisScript inside procedures 2019-07-17 15:02:44 -04:00
Michael "Z" Goddard e1254bd8c7 elevate stack block id and frame info into thread 
- Add pointer member to thread. This is the current executing block.
- Add stackFrame member to thread. This is the current frame
  information like procedure parameters.

This is a step potentially towards stack-less threads. With further
modifications we could have stack and stackFrames be null if a script
does not call a procedure.
 2019-06-03 18:13:01 -04:00
Michael "Z" Goddard 20ff75b776 fix: initialize stack frame params for all procedures 
A previous change fixed compatibility with Scratch 2 removing 3's
unintentional scope leaking. This furthers that change so that
procedures with no parameters will also not accidentally use values in
other procedure stacks.

Michael "Z" Goddard d2c637a621 fix asynchronous block execution 
Freeze promise waiting blocks into an array of reported values. Thaw
those reported values into parent values of matching blocks by id. If
the reporting block was waiting on a promise and reported a value
assign it to its parent value at that future time.
 2018-07-13 00:04:49 -04:00
Michael "Z" Goddard 05291aa254 turn reporter tree into instruction sequence 
Turn the reporter tree execute walks into a sequence of block
functions. After calling a block function store the reported value in
the arguments object its depending block will use.

- Set the reported value on the thread. There is only ever one "just"
  reported value, which is read and stored elsewhere after being
  reported.

Michael "Z" Goddard 0634e962a8 Add Thread.StackFrame class 
Use a private StackFrame class to help internally manage use of Stack
Frame values and memory. Create params, reported, and executionContext
on demand.
 2018-05-07 11:20:26 -04:00
Michael "Z" Goddard 02dd9a8c22 Unset justReported after reading its value 
Avoid justReported values leaking to other argValues by setting back to the
default null value.
