[Lldb-commits] [lldb] [lldb][test] Increase polling in TestInterruptThreadNames.py (PR #201554)

[Raphael Isemann via lldb-commits]

https://github.com/Teemperor created https://github.com/llvm/llvm-project/pull/201554

This test runs for a very long time on my machine (11s per variation), and nearly all of this time is spent on the 10s sleep in this function.

There are two issues here:

1. It uses the (now outdated) logic that arm64 means we have a remote Darwin device. This is no longer true these days as Macs also run on arm64.

2. The polling duration of 1s is still very long, and the test will still spend all its time just waiting for this 1s sleep. A 100ms sleep that we poll in a loop should be slow enough.

Subject: [PATCH] [lldb][test] Increase polling in TestInterruptThreadNames.py

This test runs for a very long time on my machine (11s per variation),
and nearly all of this time is spent on the 10s sleep in this function.

There are two issues here:

1. It uses the (now outdated) logic that arm64 means we have a remote
Darwin device. This is no longer true these days as Macs also run on
arm64.

2. The polling duration of 1s is still very long, and the test will
still spend all its time just waiting for this 1s sleep. A 100ms sleep
that we poll in a loop should be slow enough.
