From 724119a979f8f28c9e2acf92b95ef0c476768e65 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 3 Feb 1999 00:18:53 +0000 Subject: [PATCH] Modify int8 to not depend on sscanf(), and fix configure's test for int8 support. configure now checks only snprintf() for int8 support, not sprintf and sscanf as it used to. The reason for doing this is that if we are supplying our own snprintf code (which does handle long long int), we now only need working long long support in the compiler not in the platform's C library. I have verified that int8 now passes regression test on HPUX 9, and I think it should work on SunOS 4.1.* and other older platforms if gcc is used. --- src/backend/utils/adt/int8.c | 24 +- src/configure | 485 ++++++++++++++++++----------------- src/configure.in | 157 ++++++------ 3 files changed, 344 insertions(+), 322 deletions(-) diff --git a/src/backend/utils/adt/int8.c b/src/backend/utils/adt/int8.c index 4ffdcbf225..f97b352bf2 100644 --- a/src/backend/utils/adt/int8.c +++ b/src/backend/utils/adt/int8.c @@ -37,17 +37,31 @@ int64 * int8in(char *str) { int64 *result = palloc(sizeof(int64)); + char *ptr = str; + int64 tmp = 0; + int sign = 1; if (!PointerIsValid(str)) elog(ERROR, "Bad (null) int8 external representation", NULL); - if (sscanf(str, INT64_FORMAT, result) != 1) + /* Do our own scan, rather than relying on sscanf which might be + * broken for long long.
