The full buildd log is here:
https://buildd.debian.org/status/fetch.php?pkg=matrix-synapse&arch=riscv64&ver=1.128.0-1&stamp=1746950558&raw=0
My solution to this issue:
The `test_lock_contention` test, which simulates high lock contention, is
timing out on RISC-V systems likely due to inherent performance differences
of the architecture compared to more established platforms like x86_64, for
which the current 5-second timeout is calibrated.
To address this without masking potential regressions on other
architectures, I propose to conditionally adjust the timeout duration for
the RISC-V architecture. This is achieved by detecting the architecture
using `platform.machine()` within the test case and applying a more lenient
timeout (e.g., 15 seconds) specifically for RISC-V.The debdiff patch is in
the attachment.I have tested that locally,and it works well.Please let me
know whether this solution can be accepted.
