+0.9.13 release notes
|
|
|
+
|
|
|
+new features:
|
|
|
+- iconv support for EUC-KR and Big5 (including HKSCS) encodings
|
|
|
+- field widths (POSIX 2008 feature) in strftime
|
|
|
+- recurive rpath and $ORIGIN support in dynamic linker
|
|
|
+- cpu affinity interfaces
|
|
|
+- support for armhf (hardfloat) floating point environment (fenv)
|
|
|
+- support for SSE fenv on i386 (for apps using -mfpmath=sse -msse2)
|
|
|
+- strftime %s format (seconds since the epoch, future POSIX requirement)
|
|
|
+- configure script now saves its command line as a comment in config.mak
|
|
|
+- legacy functions valloc and euidaccess
|
|
|
+
|
|
|
+performance:
|
|
|
+- optimized asm memcpy for arm
|
|
|
+- optimized asm memset for i386 and x86_64
|
|
|
+- optimized C versions of memcpy and memset for all archs
|
|
|
+- eliminated major spurious syscalls from posix_spawn
|
|
|
+- some math asm for armhf (hardfloat)
|
|
|
+
|
|
|
+workarounds for:
|
|
|
+- qemu-user's rt_sigaction syscall does not allow old to alias new
|
|
|
+- qemu-user's madvise always succeeds (broke pthread_getattr_np)
|
|
|
+- passing PT_INTERP to dlopen attempted to double-load libc
|
|
|
+- gcc 4.8.x generating self-referential (infinite recursion) memcpy/memset
|
|
|
+- linux's lack of support for fchdir, fchmod, fchown, fstat on O_PATH fds
|
|
|
+
|
|
|
+bugs fixed:
|
|
|
+- failure to honor flags for fchmodat and faccessat (linux syscall api flaws)
|
|
|
+- SIGEV_THREAD timer id corruption and race condition issues
|
|
|
+- timer thread TLS incorrectly keeping values from previous expiry run
|
|
|
+- ecvt/fcvt decimal position off-by-one
|
|
|
+- in symbol-versioned libs, symbol resolved to oldest instead of newest
|
|
|
+- posix_spawn not correctly reporting errno from exec failure
|
|
|
+- "make install" was not atomic (overwrote files rather than replacing)
|
|
|
+- integer overflows in strftime
|
|
|
+- unset/empty TZ variable was mishandled
|
|
|
+- strftime could crash if the struct tm did not have valid tm_zone field
|
|
|
+- failure of fenv functions to handle invalid arguments (required by ISO C)
|
|
|
+- failure of some math functions (C and i386 asm) to raise underflow flag
|
|
|
+- broken dn_expand function (previously not used internally)
|
|
|
+- race conditions with signals during fork
|
|
|
+- incorrect access check in mktemp (obsolete function)
|
|
|
+- unnecessary arbitrary limits on size of program headers in dynamic loader
|
|
|
+- text formatting bugs in output of err.h functions
|
|
|
+
|
|
|
+arch-specific bugs:
|
|
|
+- fesetenv(FE_DFL_ENV) crashed on i386
|
|
|
+- breakage of arm crt code when libc is compiled as thumb
|
|
|
+- arm/armhf (hardfloat) misidentified by configure
|
|
|
+- ambiguity of wait (exit status) macros on mips with signal number 127
|
|
