From da05e57f70d42a41a0c6f01e2440bd3efbd972d1 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 15 May 2014 15:58:05 -0400 Subject: Fix unportable setvbuf() usage in initdb. In yesterday's commit 2dc4f011fd61501cce507be78c39a2677690d44b, I tried to force buffering of stdout/stderr in initdb to be what it is by default when the program is run interactively on Unix (since that's how most manual testing is done). This tripped over the fact that Windows doesn't support _IOLBF mode. We dealt with that a long time ago in syslogger.c by falling back to unbuffered mode on Windows. Export that solution in port.h and use it in initdb. Back-patch to 8.4, like the previous commit. --- src/backend/postmaster/syslogger.c | 17 +++-------------- 1 file changed, 3 insertions(+), 14 deletions(-) (limited to 'src/backend/postmaster/syslogger.c') diff --git a/src/backend/postmaster/syslogger.c b/src/backend/postmaster/syslogger.c index 341c99d5a2e..724b8c91f8d 100644 --- a/src/backend/postmaster/syslogger.c +++ b/src/backend/postmaster/syslogger.c @@ -45,17 +45,6 @@ #include "utils/ps_status.h" #include "utils/timestamp.h" -/* - * We really want line-buffered mode for logfile output, but Windows does - * not have it, and interprets _IOLBF as _IOFBF (bozos).
