Issue being fixed or feature implemented

Waiting for 0.5s in functional test for every action is a bit excessive, especially for p2p tests that sending messages by localnetwork and waiting at least 0.5 seconds before checking if message is received.

What was done?

Decreasing default delay from 0.5s to 0.05s. It affects mostly p2p tests, but many other tests become faster too.
For quorum formation; for sporks and some other dash specific features bigger delays (0.5s, 1s) are used and they are out of scope of this PR.

How Has This Been Tested?

Speed up on CI for 30% and more.

Benefits of running locally in 20 parallel jobs are very slight. Accumulated time is decreased for 40% as expected, but total time is decreased just for 2%.
It is because the slowest tests requires many quorums to be formed and they are still slow.

be9cf82 test: fix intermittent failure in feature_governance.py waiting votes to be propagated (Konstantin Akimov)

Pull request description:

  ## Issue being fixed or feature implemented
  While implementing #6631 found instability in feature_governance.py

  ## What was done?
  Governance votes are not delivered instantly between notes. If any vote is delayed a bit the wrong amount of votes will be remembered and test will fail further when comparing its count.

  ## How Has This Been Tested?
  Tested locally with changes from #6631
  without them - 90+% probability feature_governance.py to fail, with them - no failure happens locally.

Bumping mocktime and generation new blocks no useful anymore

Same delay is used for Bitcoin Core. Though, it can be appliable
directly for each usages such as quorum generation or waiting
for IS lock. It happends because some functional tests not only
waiting during delay, but also does something strange such as
bumping mocktime or generating new blocks. Also, some works during
quorum generation are assuming to be done while we waiting, but it's
not properly validated after delay, just assumed as it is done.

Walkthrough

The changes adjust the polling intervals in wait loops within the test framework and related functional tests. The default sleep interval in the core wait_until and wait_until_helper functions is reduced from 0.5 seconds to 0.05 seconds, increasing polling frequency. Method signatures for wait_for_quorum_list and wait_for_quorums_list are updated to remove the sleep parameter, and their internal logic is simplified to direct state checks without mocktime or block generation steps. One test explicitly sets a 1-second sleep interval for a specific wait loop. No changes are made to the logic of the conditions being waited on.

test/functional/test_framework/util.py (1)

250-250: Approve reducing the default sleep interval

This change reduces the default sleep interval in wait_until_helper from 0.5 seconds to 0.05 seconds, which will make polling 10x more frequent in wait loops throughout the test framework.

test/functional/feature_mnehf.py (1)

232-232: Explicitly setting a slower polling interval for EHF activation

This change explicitly sets a 1-second sleep interval for this specific wait condition, overriding the new 0.05-second default. This is appropriate since waiting for EHF activation doesn't need the frequent polling that other operations might benefit from.

test/functional/test_framework/test_framework.py (4)

901-901: Approve reducing default sleep interval in wait_until

Reduced the default sleep parameter from 0.5 to 0.05 seconds, consistent with the change in util.py.

1680-1680: Approve wait_for_sporks_same still using 1-second sleep

This wait function still uses a 1-second sleep interval, which is appropriate for spork synchronization that doesn't need frequent polling.

1802-1807: Simplify wait_for_quorum_list with faster polling

The method has been simplified to directly check for quorum hash presence without additional side effects like block generation or mocktime bumping. Now uses the faster 0.05-second sleep interval.

1808-1813: Simplify wait_for_quorums_list with faster polling

Similar to wait_for_quorum_list, this method has been simplified to directly check for multiple quorum hashes without side effects, using the faster 0.05-second sleep interval.
