> > You are right, details are the devil. Maybe, we can add a size field as the first member of tls_info_s, to reduce the code need to check whether the caller come from the main task or the background/work thread. > > I am beginning to think that the best way to implement per-process globals might be the same way that we already implement other per-process, application data like file descriptor, streams, etc. Allocate then with umm_malloc(), but retain them in the group structure with the system call to access them. > Yes, it's another approach, but why not move all pure userspace stuff to the main stack? So we don't have some FILE function inside the kernel space. > With PR #3182, I will need to have per-process key and destructor data. The data itself goes in thread-specific storage, but the keys are process-wide. We should agree on a technical approach. Without some agreement, I think I will need to implement the initial version with more system-wide global data. > > I will need to do that tomorrow so I can't really wait, but I don't mind reworking as necessary at a later point in time. > > This discussion really should be in Issue #3168 which is more in line with topic. -- This is an automated message from the Apache Git Service.
