This sounded like the right approach at first, but I'm not that sure that it really makes sense to have different sizes of read buffers: the per-connection read buffer only needs to keep data that is needed to parse one full command, be it plain text, encrypted and/or compressed. Then ngIRCd should handle this one command, move leftover data to the beginning of the buffer and read the next chunk from the network that is missing to get the next complete command (512 bytes at max). So I revert this for now and try to fix the logic in Read_Request(), which is broken nevertheless, as it results in servers becoming disconnected during "server burst" when "big" lists are transferred.

Commit: 8d414b079c1b4b0b8c88c8ab5cf4b27bf0942752 https://github.com/ngircd/ngircd/commit/8d414b079c1b4b0b8c88c8ab5cf4b27bf09… Author: Alexander Barton <alex(a)barton.de> Date: 2020-05-03 (Sun, 03 May 2020) Changed paths: M src/ngircd/conf.c Log Message: ----------- Correctly use Config_Error() instead of Log() in Read_Config() The name of the Config_Error() function is misleading: it is not only used to show configuraton errors, but all messages shown during normal operation as well as for "config testing": it takes care of the correct formatting of the messages (syslog, forground logging, config testing). This fixes commit bb1d014abad8. Compare: https://github.com/ngircd/ngircd/compare/71e9bb1ca637...8d414b079c1b
