From ccc899c7f4751ba72dcd7330c55614cf986f0fa3 Mon Sep 17 00:00:00 2001 From: Christoph Biedl Date: Tue, 25 Aug 2015 18:12:05 +0200 Subject: [PATCH] Reproducible builds At the moment ngircd fails the tests for reproducible builds in Debian since it uses the __DATE__ and __TIME__ macros for the INFO command. Instead of patching this out I decided to implement an optional constant BIRTHTIME that allows you to set a time stamp for the "Birth Date" information, in seconds since the epoch, like in export CFLAGS += -DBIRTHTIME=$(shell date +%s --date="2015/08/15 23:42:22") In the future, Debian will provide a SOURCE_DATE_EPOCH environment variable, dealing with the situation until then will be my job. The time format was taken from the NGIRCd_StartStr formatting in ngircd.c so the "Birth Date" and "On-line since" lines in the INFO output look similar: :irc.example.net 371 nick :ngIRCd 22.1-IDENT+IPv6+IRCPLUS+PAM+SSL+SYSLOG+ZLIB-x86_64/pc/linux-gnu :irc.example.net 371 nick :Birth Date: Tue Aug 25 2015 at 18:11:11 (CEST) :irc.example.net 371 nick :On-line since Tue Aug 25 2015 at 18:11:33 (CEST) :irc.example.net 374 nick :End of INFO list The format of the time stamped is changed, but as far as I can tell, there's no rule that is violated by that. Bonus level: Reformat the messages so the time stamps are aligned. --- src/ngircd/irc-info.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/src/ngircd/irc-info.c b/src/ngircd/irc-info.c index 1bbaf57b..1788bf60 100644 --- a/src/ngircd/irc-info.c +++ b/src/ngircd/irc-info.c @@ -558,7 +558,15 @@ IRC_INFO(CLIENT * Client, REQUEST * Req) NGIRCd_Version)) return DISCONNECTED; -#if defined(__DATE__) && defined(__TIME__) +#if defined(BIRTHDATE) + char t_str[60]; + time_t t = BIRTHDATE; + (void)strftime(t_str, sizeof(t_str), "%a %b %d %Y at %H:%M:%S (%Z)", + localtime(&t)); + snprintf(msg, sizeof(msg), "Birth Date: %s", t_str); + if (!IRC_WriteStrClient(Client, RPL_INFO_MSG, Client_ID(prefix), msg)) + return DISCONNECTED; +#elif defined(__DATE__) && defined(__TIME__) snprintf(msg, sizeof(msg), "Birth Date: %s at %s", __DATE__, __TIME__); if (!IRC_WriteStrClient(Client, RPL_INFO_MSG, Client_ID(prefix), msg)) return DISCONNECTED; -- 2.39.2
