# WiredTiger is known to cause false positives for data races because it uses a
|
|
# nonstandard thread model that TSAN doesn't know how to deal with. We have
|
|
# already denylisted WiredTiger in TSAN, but that only affects threads created
|
|
# within the WiredTiger source. For threads that call *into* WiredTiger, we
|
|
# need to add suppressions so we still get any potential failures from
|
|
# elsewhere.
|
|
#
|
|
# This is a temporary addition for now because it's possible that these are
|
|
# real positives that we need to do something with. However, because we know
|
|
# that false positives are more likely, we're deferring them until we have
|
|
# fixed the ones we know are real.

# no correctness issue. The third counter is just used for logging. We only expect these data races

# to be possible in the context of a partial index with a geo-related partialFilterExpression, since
