Summary

Remove redundant null pointer checks before delete and free() calls in three locations identified in #53.

In C++, delete nullptr is guaranteed to be a no-op by the standard (ISO C++ FAQ). Similarly, free(NULL) is defined as a no-op by the C standard (C11 §7.22.3.3).

Changes

  • fst/xrdcl_plugins/RainFile.cc — Removed if (pFile) and if (pRainFile) guards in the RainFile destructor
  • fst/http/s3/S3Handler.cc — Removed if (mFile) guard in HandleRequest; the delete and subsequent null assignment are preserved
  • auth_plugin/ProtoUtils.cc — Removed if (obj->reqid) and if (obj->notify != nullptr) guards before free() in DeleteXrdSfsPrep

Fixes #53

delete on a null pointer is guaranteed to be a no-op by the C++
standard, and free(NULL) is a no-op per C11 §7.22.3.3. The redundant
guards add visual noise without providing any safety benefit.
