From: Jeremy Harris Date: Fri, 8 Apr 2016 18:37:13 +0000 (+0100) Subject: Testsuite: 0322 (pipelining errors) avoid triggering SIGPIPE X-Git-Tag: exim-4_88_RC1~129 X-Git-Url: https://vcs.fsf.org/?p=exim.git;a=commitdiff_plain;h=b9d9c5a27bea03802901872e0e056fb97b4c30a6 Testsuite: 0322 (pipelining errors) avoid triggering SIGPIPE This was timing-dependent; if the exim closed the connection before the script wrote to it _after_ triggerring an error, EPIPE/SIGPIPE. Unexplained as yet: why runtest (perl) saw this as a 141 server returncode (NB: 141-128 = 13 = SIGPIPE, the shell behaviour) when "perldoc -v '$?'" (which runtest is coded to) says that a signum should be in the top nibble of 16b. --- diff --git a/src/src/transports/smtp.c b/src/src/transports/smtp.c index 975fc16aa..6741c01a6 100644 --- a/src/src/transports/smtp.c +++ b/src/src/transports/smtp.c @@ -2958,6 +2958,7 @@ writing RSET might have failed, or there may be other addresses whose hosts are specified in the transports, and therefore not visible at top level, in which case continue_more won't get set. */ +HDEBUG(D_transport|D_acl|D_v) debug_printf(" SMTP(close)>>\n"); (void)close(inblock.sock); #ifndef DISABLE_EVENT diff --git a/test/runtest b/test/runtest index f6e57b4b5..fa38ca019 100755 --- a/test/runtest +++ b/test/runtest @@ -1977,6 +1977,7 @@ if (/^(ln|ls|du|mkdir|mkfifo|touch|cp|cat)\s/ || # command, triggered by $server_pid being non-zero.
