``` * This function gets called either from conn_write_callback() in main.c * when libevent tells us that conn wants to write, or below * from connection_buf_add() when an entire TLS record is ready. ``` _, or below ... when an entire TLS record is ready_ hasn't been accurate since [d9746bd468f551d1ada57d962b20eddd15256ce9](https://gitweb.torproject.org/tor.git/commit/?id=d9746bd468f551d1ada57d962b20eddd15256ce9). It and connection_handle_read_impl also don't mention only ever being called indirectly via `connection_handle_write()`/read since [d3be00e0f454998db6387c8547d218a0db93db21](https://gitweb.torproject.org/tor.git/commit/?id=d3be00e0f454998db6387c8547d218a0db93db21), but that's more readily apparent at least. **Trac**: **Username**: cyberpunks
