* MFC r313774: localtime: return NULL if time_t out of range of struct tmEd Maste2017-03-011-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously we would truncate tm.tm_year for any time_t corresponding to a year that does not fit in int. This issue was discovered because it caused the bash-static build to fail when linking with LLD. As reported by Rafael Espíndola: Configure has AC_FUNC_MKTIME which expands to a test of mktime that fails with the freebsd implementation. Given that, bash compiles a mktime.o file that defines just mktime and uses localtime. That goes in a .a file that is before libc. The freebsd libc defines mktime in localtime.o, which also defines localtime among other functions. When lld sees an undefined reference to mktime from libc, it uses the bash provided one and then tries to find a definition of localtime. It is found on libc's localtime.o, but now we have a duplicated error. The reason it works with bfd is that bash doesn't use mktime directly and the undefined reference from libc is resolved to the libc implementation. It would also fail to link if bash itself directly used mktime. The bash-static configure test verifies that, for many values of t, either localtime(t) returns NULL or mktime(localtime(t)) == t. This test failed when localtime returned a truncated tm_year. This was fixed in tzcode in 2004 but has persisted in our tree since rS2708.

| | | | | | | | | | | | | | | The stdtime sources were moved from lib/libc to contrib/tzcode, and tzfile.h is not an installed header, so the man page refers to its location in the source tree. The documentation could be more clear about the internal nature of the header, but those changes should go through upstream tzcode.
