From 96062a181db0f00bb14898e1ec40072ebefa9855 Mon Sep 17 00:00:00 2001 From: Willy Tarreau Date: Sun, 11 Nov 2018 14:00:28 +0100 Subject: [PATCH] BUILD: cache: fix a build warning regarding too large an integer for the age Building on 32 bit gives this : src/cache.c: In function 'http_action_store_cache': src/cache.c:466:4: warning: this decimal constant is unsigned only in ISO C90 [enabled by default] src/cache.c:467:5: warning: this decimal constant is unsigned only in ISO C90 [enabled by default] src/cache.c: In function 'cache_channel_append_age_header': src/cache.c:578:2: warning: this decimal constant is unsigned only in ISO C90 [enabled by default] src/cache.c:579:3: warning: this decimal constant is unsigned only in ISO C90 [enabled by default] It's because of the definition below added in commit e7a770c ("MINOR: cache: Add "Age" header.") : #define CACHE_ENTRY_MAX_AGE 2147483648 Just appending "U" to mark it unsigned is enough to fix it. This only affects 1.9, no backport is needed. --- src/cache.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/cache.c b/src/cache.c index 6988b15be..35568bc55 100644 --- a/src/cache.c +++ b/src/cache.c @@ -73,7 +73,7 @@ struct cache_entry { }; #define CACHE_BLOCKSIZE 1024 -#define CACHE_ENTRY_MAX_AGE 2147483648 +#define CACHE_ENTRY_MAX_AGE 2147483648U static struct list caches = LIST_HEAD_INIT(caches); static struct cache *tmp_cache_config = NULL;
