steakhal added a comment.
I would rather match on the complete line (except the file descriptor ofc).
By inspecting the output that is piped to the `count`, I have a suspicion:
openat(AT_FDCWD, "invocations.yaml", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such
file or directory)
It should have found it! It exists, but ill-formed. @martong what did we
misconfigure?
My guess is that `ctu-invocation-list` is not using the `ctu-dir`. It should be
a different bug though.
To workaround this issue, simply use an absolute path for the invocation yaml.
What about this?
// RUN ... 2>&1 | grep 'invocations\.yaml' | FileCheck %s
void foo() {
// It finds the invocation yaml, then it tries to parse it which expected
to fail.
bar();
// CHECK: openat(AT_FDCWD, "{{[^"]+}}invocations.yaml", O_RDONLY|O_CLOEXEC)
= {{[0-9]+}}
// We should remember that the parsing failed, we shouldn't try to reopen
and parse the yaml again.
bar();
// CHECK-NOT: openat(AT_FDCWD, "{{[^"]+}}invocations.yaml",
O_RDONLY|O_CLOEXEC) = {{[0-9]+}}
}
This way we are sure that the file opened (it resulted in a non-negative file
descriptor) and opened only once!
