#4848 closed defect (fixed)

CPLOpenShared() doesn't behave nicely in a multi-threaded scenario

Reported by: Even Rouault Owned by: warmerdam
Priority: normal Milestone: 1.9.2
Component: default Version: unspecified
Severity: normal Keywords: CPLOpenShared VRTRawRasterBand threads


Reported as

VRTRawRasterBand uses CPLOpenShared() to open the raw file. If 2 threads open the same VRT, they will currently share the same handle to the raw file, which will lead to chaos.

To avoid that, CPLOpenShared() must take into account the thread ID.
