We don't need to implement any openssl locking > functions. It does not matter whether you think the locking functions are needed or not. It's matter what openssl developers think and what assumptions they did when developed the library. As I see they expressed it pretty clear - some globals are implicitly shared among threads and this alone may cause crashes if locks are not used. Do you have any _strong_ reason to believe they are wrong? They didn't say that it's SSL_CTX is the global struct that will be implicitly shared. Even if you're correct and SSL_CTX is "the global", why would they need 32 locks synchronizing access to it? > An example of non-thread safe is gettext it relies on the locale which is > per process and not per-thread. > PHP itself at the core is thread safe.
