From 22d57dd3690a0fe623de1a56036306a93fa9a945 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 2 Apr 1997 14:47:34 +0000 Subject: Update. 1997-04-02 16:28 Ulrich Drepper * grp/fgetgrent.c: Don't use fixed buffer length. Allow dynamic adjustment if the underlying function say it is too small. * pwd/fgetpwent.c: Likewise. * shadow/fgetspent.c: Likewise. * shadow/sgetspent.c: Likewise. * grp/fgetgrent_r.c (__fgetgrent_r): If `parse_result' returns -1 this means there was not enough room for the gr_mem array. * nss/nss_files/files-XXX.c: Leave loop and return error if `parse_result' returns -1. * nss/nss_files/files-parse.c (parse_line): Return -1 if parsing of trailing list fails because of low memory. (parse_list): Rewrite. The logic was completly incorrect since the checks for overflowing the array were not executed when needed. * shadow/sgetspent_r.c: Only a return value > 0 from parse_line signals success. * nss/getXXbyYY.c: Make sure NULL is returned if we ran out of memory. * nss/getXXent.c: Likewise. * stdlib/strtod.c (SET_MANTISSA): Make sure that at least one bit is set in mantissa. * stdlib/strtof.c: Likewise. * stdlib/strtold.c: Likewise. * wcsmbs/wcstof.c: Likewise. * wcsmbs/wcstold.c: Likewise. * sysdeps/libm-ieee754/s_nan.c: Use strtod is parameter is not empty string. * sysdeps/libm-ieee754/s_nanf.c: Likewise. * sysdeps/libm-ieee754/s_nanld.c: Likewise. 1997-04-02 13:56 Ulrich Drepper * manual/errno.texi: Add description of strerror_r. 1997-04-01 19:07 H.J. Lu (hjl@gnu.ai.mit.edu) * manual/errno.texi: Add ENOMEDIUM and EMEDIUMTYPE. 1997-04-02 13:55 Ulrich Drepper * sysdeps/gnu/errlist.awk: The Texinfo file is named errno.texi. 1997-03-30 10:59 Andreas Schwab * sysdeps/m68k/fpu/s_cexp.c: New file. * sysdeps/m68k/fpu/s_cexpf.c: New file. * sysdeps/m68k/fpu/s_cexpl.c: New file. * sysdeps/m68k/fpu/s_nearbyint.c: New file. * sysdeps/m68k/fpu/s_nearbyintf.c: New file. * sysdeps/m68k/fpu/s_nearbyintl.c: New file. * sysdeps/m68k/fpu/s_trunc.c: New file. * sysdeps/m68k/fpu/s_truncf.c: New file. * sysdeps/m68k/fpu/s_truncl.c: New file. * sysdeps/m68k/fpu/s_modf.c: Rewritten. * sysdeps/m68k/fpu/s_modff.c: Adapted. * sysdeps/m68k/fpu/s_modfl.c: Likewise. * sysdeps/m68k/fpu/e_atan2.c: Use __signbit inline. * sysdeps/m68k/fpu/e_pow.c: Likewise. Write 0.0/0.0 for NaN. Fix typo in test for `y = 0.5'. * sysdeps/m68k/fpu/__math.h: Define __trunc, __signbit, __nearbyint. Remove __modf. * sysdeps/m68k/Makefile (CFLAGS-s_copysignl.c) [$(subdir)=math]: Define for gcc bug workaround. * math/libm-test.c (log2_test): Add epsilon for long double to "log2 (e)" and "log2 (16)". (modf_test): Fix test name. (sqrt_test): Add missing FUNC. 1997-03-29 16:24 Andreas Schwab * sunrpc/Makefile (CFLAGS-xrquota.c): Fix typo in variable name. 1997-03-28 20:56 Andreas Schwab * stdlib/stdlib.h: Declare __clearenv. 1997-03-28 18:03 Andreas Schwab * sysdeps/libm-ieee754/s_asinhl.c: Fix Ulrich Dreppers mangling of the last change. 1997-03-28 17:55 Andreas Schwab * configure.in: Call AC_CANONICAL_BUILD before referencing $build. Fix test for BUILD_CC. 1997-04-02 01:29 Philip Blundell * sysdeps/libm-ieee754/s_log2f.c (__log2f): Fix typo. 1997-03-31 18:53 Philip Blundell * sysdeps/unix/sysv/linux/net/route.h: Add new IPv6 definitions. 1997-04-01 14:08 Ulrich Drepper * sysdeps/i386/memset.c: Fix typo. * sysdeps/stub/fchmod.c: Fix typo. * sysdeps/stub/fchdir.c: Fix typo.
