On iterator remove, the iterator will trade the read lock for a write
lock, and trade back for a read lock once the remove has been completed.

Stephen Seo 611287b377 Revert "Impl "RWLock" for use in TSLQueue" 
This reverts commit cf27a6bb76.

The use of "shared_lock" in TSLQueue is unsafe because of two things:

  - The TSLQueue iterator takes a "read" lock.
  - The TSLQueue iterator can erase the current element.

Stephen Seo cf27a6bb76 Impl "RWLock" for use in TSLQueue 
This project supports C++11, and std::shared_lock was made available in
C++17, thus a "shared_spin_lock" was created with similar functionality.
This "shared_spin_lock" is used in TSLQueue.

Stephen Seo 77d69cabbc Impl "unsafe" versions of UDPC_atostr(...) 
These "unsafe" versions are guaranteed to not have the returned address
strings be overwritten by UDPC, but they must be manually free'd later
(as mentioned in the documentation).
 2023-06-22 13:25:26 +09:00
Stephen Seo 4abd9fddcb Conditionally use UDPC_atostr internally 
Previous implementation used UDPC_atostr() frequently. This commit
changes the implementation to only call UDPC_atostr() if the log level
of the code logging to output will cause the log to be output.

Stephen Seo 390f3972f8 Add documentation for UDPC_atostr... 2023-06-22 12:07:26 +09:00
Stephen Seo 2495396d76 Fix potential memory corruption bug 
UDPC_atostr(...) uses a uint32_t as an offset into a buffer inside the
UDPC Context such that there can be at most 32 different addr-strings.
The call is thread-safe, up to a point (at most 32 concurrent calls will
return correct strings). The problem was that the offset was not being
reset to 0 and was always being incremented by 40. Should the offset
overflow, the offset into the buffer will be "mis-aligned" such that the
32nd offset into the buffer can possibly overwrite memory past the
buffer's end if the addr string is long enough.

The fix is to use a mutex instead of an atomic uint32_t to lock a
code-block that will always prevent overflow (using modulus operator).

I think the speed-loss is negligable (using a lock instead of an atomic
uint32_t) since it isn't expected for programs using UDPC to use
UDPC_atostr(...) very frequently.
