Summary: TSAN reports that our stack trace handler makes unsafe calls during a signal handler. I just tried fixing some of them and I don't think it's fixable unless we can get away from using FILE stdio. Even if we can use lower level functions only, I'm not sure it's fixed. I also tried suppressing the reports with function and file level TSAN suppression, but that doesn't seem to work, perhaps because the violation is reported on the callee, not the caller. So I added a warning to be printed whenever these violations would be reported that they are practically ignorable. Internal ref: T77844138 Pull Request resolved: https://github.com/facebook/rocksdb/pull/7723 Test Plan: run external_sst_file_test with seeded abort(), with TSAN (TSAN warnings + new warning) and without TSAN (no warning, just stack trace).

This directory contains interfaces and implementations that isolate the rest of the package from platform details. Code in the rest of the package includes "port.h" from this directory. "port.h" in turn includes a platform specific "port_<platform>.h" file that provides the platform specific implementation. See port_posix.h for an example of what must be provided in a platform specific header file.
