This refactoring is in preparation for adding support for other SSL implementations, with no user-visible effects. There are now two #defines, USE_OPENSSL which is defined when building with OpenSSL, and USE_SSL which is defined when building with any SSL implementation. Currently, OpenSSL is the only implementation so the two #defines go together, but USE_SSL is supposed to be used for implementation-independent code. The libpq SSL code is changed to use a custom BIO, which does all the raw I/O, like we've been doing in the backend for a long time. That makes it possible to use MSG_NOSIGNAL to block SIGPIPE when using SSL, which avoids a couple of syscall for each send(). Probably doesn't make much performance difference in practice - the SSL encryption is expensive enough to mask the effect - but it was a natural result of this refactoring. Based on a patch by Martijn van Oosterhout from 2006. Briefly reviewed by Alvaro Herrera, Andreas Karlsson, Jeff Janes. |
