------------------------------------------
Summary: PpidChecker inherits and blocks resources from tests
while checking if the forked VM is still alive
Key: SUREFIRE-1573
URL: https://issues.apache.org/jira/browse/SUREFIRE-1573
Project: Maven Surefire
Issue Type: Bug
Affects Versions: 2.22.0
Environment: Windows, our tests create temporary files using
native-code (std::fstream) and remove or rename them using boost::filesystem.
Reporter: Marcus Ackermann
On Windows, the PpidChecker executes wmic through cmd by starting a new
process. Java calls {{CreateProcess}} with the flag {{bInheritHandles=TRUE}}.
When I create a temporary file in a test, it happens that this file can neither
be removed nor deleted. The error code is the following (from
https://docs.microsoft.com/en-us/windows/desktop/debug/system-error-codes--0-499-)
{code:java}
ERROR_SHARING_VIOLATION
32 (0x20)
The process cannot access the file because it is being used by another
process.{code}
I found out that this sharing violation is due to the fact that the process
started from PpidChecker also owns the file inherited from the test process.
This seems to be a side-effect of the new monitoring mechanism for the forked
VM introduced in 2.20.1 with SUREFIRE-1302.
