The number of tasks that are spawned is ~300 (`294` for me, but it will likely be more in the future). So even if you run each task only for a minute, it will take longer than 4 hours already. But running for a minute seems entirely useless, so I am not sure if it is worth optimizing for. (For smoke testing I just edit this script to `-max_total_time=6`).

In any way, you can pass `--par 999` to run everything at the same time and be done in 100 minutes.

However, to avoid an edit for smoke

Ok i'm confused. I'm aware i just gave this a superficial look but i'm absolutely not following here. *(Last comment and if i don't get it i'll look into it more in depth.)*

> The number of tasks that are spawned is ~300

How comes? The default for `--par` is `4`.

> So even if you run each task only for a minute, it will take longer than 4 hours already

How could, with 300 tasks, running 169 tasks for 1 minute take 4 hours?

> How comes?

Sorry, with "The number of tasks that are spawned is ~300" I meant "The number of tasks that are spawned over the full runtime of the python script is ~300".

> How could

For example, with `-j1`: Running 300 1-minute-tasks spawned sequentially on one thread will take 300 minutes. (5 hours). Though, the main point is that 1 minute of runtime is useless. So optimizing for a short default runtime will quickly get you to make the entire script useless.

`pop two` doesn't quite work (IMO).

it makes the order somewhat ambiguous.

for example:

`pop pop add push` is more correct. no?

Being more explicit in this way will make the `OP_SUB` make more sense, no?.

`pop pop subtract push`


for `OP_ADD` it isn't much of an issue.

`` 1 + 1 = 2 ``

`` 1 + -1 = 0 ``

`` -1 + 1 = 0 ``




for `OP_SUB` it may be an issue.

``1 - 1 = 0``

``1 - -1 = 0``

``-1 - 1 = -2``

*in common arithmetic notation

Indeed a too short runtime could make the script useless (since people would basically start running it in a loop itself), but a too long one would likely introduce a bias toward the first (alphabetically sorted) targets.

I guess it would be helpful to know who uses this script and how. For instance if they are continuously generating coverage most likely they are already running it in a loop of some sort and therefore a runtime of like 10minutes per target would spead the time spent over all

Nice, do you happen to know why they don't only set it to `1` when `-jobs` is not `0`?

It is possible to launch multiple libFuzzer *manually* on the same folder, but this script doesn't do it, and it seems unlikely that a user would do it.

Little topic, mainly to not mix RPC commands responsibilities.

Why not implementing this on the test framework instead?

Could add a proxy function `mockscheduler` to `test_node.py` that calls to the real `mockscheduler` and, subsequently to `syncwithvalidationinterfacequeue`.

> Why not implementing this on the test framework instead?

That just seems brittle, and bloated, for no reason? It is brittle because one may miss to implement a proxy, as they'll have to be done for the bitcoin-cli utility and the python rpc wrapper, and devs can still accidentally sidestep it. It is bloated because it will be more than one line of code.

Same question for `RaiseValidity`, which this PR doesn't touch. Contrast that to `CheckBlockIndex()` which skips checks for `BLOCK_VALID_TRANSACTIONS`, `BLOCK_VALID_CHAIN` and `BLOCK_VALID_SCRIPTS` when assume valid is set.

The documentation commit made me wonder if we can use `BLOCK_VALID_SCRIPTS` (the first check beyond headers) instead of `BLOCK_VALID_TRANSACTIONS` to set `BLOCK_ASSUMED_VALID`.
