HAProxy - Load balancer
0d1e99c086
Don't directly call functions that take date as argument and output the string representation to the log output buffer under sess_build_logline(), and instead build the strings in temporary buffers of fixed size (hopefully such functions, such as date2str_log() and gmt2str_log() procuce strings of known size), and then print the result using lf_rawtext() helper function. This way, we will be able to encode them automatically as regular string/text when new encoding methods are added. Because of this patch, we add a little overhead because we first generate the text into a temporary variable and then use lf_rawtext() to print it. Thus we have a double-copy, and this could have some performance implications that were not yet evaluated. Due to the small number of bytes that can end up being copied twice (< 30), we could be lucky and have no visible performance impact, but if we happen to see a significant impact, it could be useful to add a passthrough mechanism (to keep historical behavior) when no encoding is involved. |
