#10720: boost::interprocess Windows semaphore and mutex creation can fail due to
naming convention
---------------------------------------------+--------------------------
Reporter: Ville Outamaa <ville.outamaa@â¦> | Owner: igaztanaga
Type: Bugs | Status: new
Milestone: To Be Determined | Component: interprocess
Version: Boost 1.54.0 | Severity: Problem
Keywords: |
---------------------------------------------+--------------------------
boost::interprocess names the mutexes and semaphores using the sync_id and
sync_handles classes found in interprocess/sync/windows/sync_utils.hpp.
The sync_id class uses winapi::query_performance_counter to obtain a value
which is then used to create a supposedly unique identifier for the
semaphore or mutex in sync_handles::fill_name.
The problem is that when multiple mutexes and/or semaphores are created
within such a short time frame that the value returned by
winapi::query_performance_counter does not change, the creation fails with
winapi::error_already_exists.
