file.c: move utime parser to a separate file * utime.c: New file. * Makefile.am (strace_SOURCES): Add it. * file.c (sys_utime): Move to utime.c. 2014-12-06 06:53:16 +03:00			`#include "defs.h"`

Mpersify parser of utime syscall Fix multiple personalities support in parser of utime syscall by using mpersified utimbuf_t typedef. * utime.c (utimbuf_t): New typedef. Mpersify it.

Declare syscall parsers using SYS_FUNC macro Introduce SYS_FUNC macro to declare and define all syscall parsers. * Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h. (sys_func.h): New rule. * defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros. * linux/syscall.h: Include "sys_func.h". [NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers. Remove other declarations. * linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs and osf_fstatfs syscall parsers. * *.c: Use SYS_FUNC to define syscall parsers. 2015-04-07 04:36:50 +03:00			`SYS_FUNC(utime)`

Always print raw values of time data fields Refactor sprinttime: implement sprinttime_nsec and sprinttime_usec that handle nanoseconds and microseconds, respectively. Always print raw values of time data fields, format string representations of time as comments. * defs.h (sprinttime): Change argument type from time_t to long long. (sprinttime_nsec, sprinttime_usec): New prototypes. * util.c (sprinttime_ex, sprinttime_nsec, sprinttime_usec): New functions. (sprinttime): Turn into a thin wrapper around sprinttime_ex. * stat.h (struct strace_stat): Add has_nsec field. * fetch_struct_stat.c (HAVE_NSEC): New macro. (fetch_struct_stat): Initialize has_nsec field with HAVE_NSEC. * fetch_struct_stat64.c (HAVE_NSEC): New macro. (fetch_struct_stat64): Initialize has_nsec field with HAVE_NSEC. * print_struct_stat.c (print_struct_stat) <PRINT_ST_TIME>: Print raw values of time fields, use sprinttime_nsec to format a string representation of time, use tprints_comment to print it as a comment. * statx.c (SYS_FUNC(statx)) <PRINT_FIELD_TIME>: Likewise. * utime.c (SYS_FUNC(utime)): Print raw values of struct utimbuf.actime and struct utimbuf.modtime fields, use sprinttime to format a string representation of time, use tprints_comment to print it as a comment. * tests/tests.h (print_time_t_nsec): Add int argument. * tests/print_time.c (print_time_t_ex): New function. (print_time_t_nsec): Add int argument, turn into a thin wrapper around print_time_t_ex. * tests/utime.c (main): Update expected output. * tests/xstatx.c [!IS_STATX] (HAVE_NSEC): New macro. [!IS_STATX] (PRINT_ST_TIME), [IS_STATX] (PRINT_FIELD_TIME): Update expected output. * NEWS: Mention this timestamps representation improvement. Co-authored-by: Dmitry V.
