Permission denied (os error 13)

corepc-node is being used for Integration Testing on Stratum V2 Reference Implementation

for a while we have been noticing a puzzling behavior, which we are tracking here stratum-mining/stratum#1278

the error logs usually look like this:

running 2 tests
thread 'success_pool_template_provider_connection' panicked at tests-integration/tests/common/mod.rs:143:61:
called `Result::unwrap()` on an `Err` value: Error while executing "/tmp/.template-provider/bitcoin-sv2-tp-0.1.9/bin/bitcoind"

Caused by:
    Permission denied (os error 13)
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

we tried fixing this in many different ways but never got to the root cause of the issue

it's important to highlight that this behavior is not deterministic... sometimes it doesn't happen at all

it seems to be somewhat related to rust-bitcoin/bitcoind#90

Can you directly try to execute that path to bitcoind?

after some deeper investigation, it seems this is likely related to some kind of race-condition in our test stack and not necessarily some bug on corepc-node
