Fixed by leaving just one implementation of rint() in our source tree, and changing its behavior to match the most common native implementations on other platforms. --- include/config-win.h | 9 --------- include/my_global.h | 35 +++++++++++++++++++++++++++++++++-- 2 files changed, 33 insertions(+), 11 deletions(-) (limited to 'include') diff --git a/include/config-win.h b/include/config-win.h index eba699159c7..ab463a7c142 100644 --- a/include/config-win.h +++ b/include/config-win.h @@ -31,7 +31,6 @@ functions */ #include #include -#include /* Because of rint() */ #include #include #include @@ -223,13 +222,6 @@ typedef uint rf_SetTimer; #define inline __inline #endif /* __cplusplus */ -inline double rint(double nr) -{ - double f = floor(nr); - double c = ceil(nr); - return (((c-nr) >= (nr-f)) ? f :c); -} - #ifdef _WIN64 #define ulonglong2double(A) ((double) (ulonglong) (A)) #define my_off_t2double(A) ((double) (my_off_t) (A)) @@ -281,7 +273,6 @@ inline ulonglong double2ulonglong(double d) #define HAVE_FLOAT_H #define HAVE_LIMITS_H #define HAVE_STDDEF_H -#define HAVE_RINT /* defined in this file */ #define NO_FCNTL_NONBLOCK /* No FCNTL */ #define HAVE_ALLOCA #define HAVE_STRPBRK diff --git a/include/my_global.h b/include/my_global.h index 845ae042a42..3f872bfc855 100644 --- a/include/my_global.h +++ b/include/my_global.h @@ -484,8 +484,39 @@ typedef unsigned short ushort; #define set_bits(type, bit_count) (sizeof(type)*8 <= (bit_count) ? ~(type) 0 : ((((type) 1) << (bit_count)) - (type) 1)) #define array_elements(A) ((uint) (sizeof(A)/sizeof(A[0]))) #ifndef HAVE_RINT -#define rint(A) floor((A)+(((A) < 0)? -0.5 : 0.5)) -#endif +/** + All integers up to this number can be represented exactly as double precision + values (DBL_MANT_DIG == 53 for IEEE 754 hardware). +*/ +#define MAX_EXACT_INTEGER ((1LL << DBL_MANT_DIG) - 1) + +/** + rint(3) implementation for platforms that do not have it. + Always rounds to the nearest integer with ties being rounded to the nearest + even integer to mimic glibc's rint() behavior in the "round-to-nearest" + FPU mode.

The server will continue after user have freed some space. But the error message printed was not quite clear about the how often the error message is printed, and there will be a delay before the server continue and user freeing space. And caused users thinking that the server was hanging forever. This patch fixed the problem by making the error messages printed more clear. The error message is split into two part, the first part will only be printed once, and the second part will be printed very 10 times. Message first part: Disk is full writing '' (Errcode: ). Waiting for someone to free space...
