Please -make sure that bugs you report are not listed here. If you can fix one -of these bugs/limitations I'll certainly be glad to receive a patch. - -Another source of information about bugs is the problem data base of the -GNU project.

Before reporting -a bug please check the FAQ since it discusses also a lot of -problematic situations. - - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Severity: [ *] to [***] - -[ **] Closing shared objects in statically linked binaries most of the - times leads to crashes during the dlopen(). Hard to fix. - -[ **] The RPC code is not 64 bit clean. This is getting slowly fixed - but expect incompatible changes on 64 bit platforms like Alpha. - -[ *] The precision of the `sinhl' and/or `asinhl' function do not seem - to be the best. - -[ *] On Linux, there should be a way to prevent defining the symbol - NGROUPS_MAX in the <linux/limits.h> header file. In glibc it - is defined in <posix1_lim.h> which must not make the other - symbols in <linux/limits.h> available. - [PR libc/140] - -[ *] The libm-ieee `gamma' function gives wrong results (at least for - -0.5). - -[ *] The libm-ieee `scalb' function gives wrong results for - non-integral second parameters. - -[ *] Several (most?) collation specifications are broken. The code which - is currently there is in most cases inherited from the originial - author (in case there is a LC_COLLATE specification in the locale - file) or is defined using the default (if iso14651_t1 is included). - - In any case we are missing information to correct the specification. - If you find the specification for your language be faulty please - send a report with instruction on what to fix. You don't have to - fix the specification yourself. - - The way it finally should look like (if the generic specification - is not correct) can be seen in the sv_SE file. Quite a few changes - on top of the generic specification can be made without duplication - of the whole LC_COLLATE description. - -[ *] Some of the functions which also handled IPv6 are currently broken. - IPv6 and IPv4 lookups occasionally happen when not needed. This - happens in getaddrinfo() and getnameinfo(). IPv4 handling of - these functions is OK though and there are patches available to fix - the IPv6 code as well. - -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -Ulrich Drepper -drepper@redhat.com diff --git a/CONFORMANCE b/CONFORMANCE deleted file mode 100644 index b23318e..0000000 --- a/CONFORMANCE +++ /dev/null @@ -1,168 +0,0 @@ -Conformance of the GNU libc with various standards -================================================== - -The GNU libc is designed to be conformant with existing standard as -far as possible.

Some -of these relate to defects in the standard that are expected to be -fixed, or to compiler limitations. - - -Defects in the C99 standard -=========================== - -Some defects in C99 were corrected in Technical Corrigendum 1 to that -standard. glibc follows the corrected specification. - - -Implementation of library functions -=================================== - -The implementation of some library functions does not fully follow the -standard specification: - -C99 added additional forms of floating point constants (hexadecimal -constants, NaNs and infinities) to be recognised by strtod() and -scanf(). The effect is to change the behavior of some strictly -conforming C90 programs; glibc implements the C99 versions only -irrespective of the standard version selected. - -C99 added %a as another scanf format specifier for floating point -values. This conflicts with the glibc extension where %as, %a[ and -%aS mean to allocate the string for the data read. A strictly -conforming C99 program using %as, %a[ or %aS in a scanf format string -will misbehave under glibc if it does not include <stdio.h> and -instead declares scanf itself; if it gets the declaration of scanf -from <stdio.h>, it will use a C99-conforming version. - - -Compiler limitations -==================== - -The macros __STDC_IEC_559__, __STDC_IEC_559_COMPLEX__ and -__STDC_ISO_10646__ are properly supposed to be constant throughout the -translation unit (before and after any library headers are included). -However, they mainly relate to library features, and GCC only knows to -preinclude <stdc-predef.h> to get their definitions in version 4.8 and -later. Programs that test them before including any standard headers -may misbehave with older compilers. - -GCC doesn't support the optional imaginary types. Nor does it -understand the keyword _Complex before GCC 3.0. This has the -corresponding impact on the relevant headers. - -glibc's <tgmath.h> implementation is arcane but thought to work -correctly; a clean and comprehensible version requires compiler -builtins. - -For most of the headers required of freestanding implementations, -glibc relies on GCC to provide correct versions. (At present, glibc -provides <stdint.h>, and GCC doesn't before version 4.5.) - -The definition of math_errhandling conforms so long as no translation -unit using math_errhandling is compiled with -fno-math-errno, --fno-trapping-math or options such as -ffast-math that imply these -options. math_errhandling is only conditionally defined depending on -__FAST_MATH__; the compiler does not provide the information needed -for more exact definitions based on settings of -fno-math-errno and --fno-trapping-math, possibly for only some source files in a program. - - -Issues with headers -=================== - -None known. diff --git a/NAMESPACE b/NAMESPACE deleted file mode 100644 index 109a13a..0000000 --- a/NAMESPACE +++ /dev/null @@ -1,66 +0,0 @@ -Header Prefix Suffix - -aio.h aio_, lio_, AIO_, LIO_ -complex.h cerf{,f,l}, cerfc{,f,l}, cexp2{,f,l}, - cexpm1{,f,l}, clog10{,f,l}, clog1p{,f,l}, - clog2{,f,l}, clgamma{,f,l}, ctgamma{,f,l} -ctype.h is[a-z], to[a-z] -dirent.h d_ -dlfcn.h RTLD_ -errno.h E -fcntl.h l_, F_, O_, S_ -fmtmsg.h MM_ -fnmatch.h FNM_ -ftw.h FTW -glob.h gl_, GLOB_ -grp.h gr_ -inttypes.h PRI[a-zX], SCN[a-zX] -limits.h _MAX -locale.h LC_[A-Z] -mqueue.h mq_, MQ_ -ndbm.h dbm_, DBM_ -nl_types.h NL_ -poll.h pd_, ph_, ps_, POLL -pthread.h pthread_, PTHREAD_ -pwd.h pw_ -regex.h re_, rm_, REG_ -sched.h sched_, SCHED_ -semaphore.h sem_, SEM_ -signal.h sa_, uc_, SIG[A-Z], SIG_[A-Z], SIG_[0-9a-z_] - ss_, sv_ - si_, SI_, sigev_, SIGEV_, sival_, SA_, - BUS_, CLD_, FPE_, ILL_, POLL_, SEGV_, SS_, SV_, TRAP_ -stdint.h int*_t, uint*_t, INT*_MAX, INT*_MIN, - INT*_C, UINT*_MAX, UINT*_MIN, UINT*_C -stdlib.h str[a-z] -string.h str[a-z], wcs[a-z] -stropts.h bi_, ic_, l_, sl_, str_, - FLUSH[A-Z], I_, M_, MUXID_R[A-Z], S_, SND[A-Z], STR -syslog.h LOG_ -sys/ipc.h ipc_, IPC_ -sys/mman.h shm_, MAP_, MCL_, MS_, PROT_ -sys/msg.h msg, MSG[A-Z], MSG_[A-Z] -sys/resource.h rlim_, ru_, PRIO_, RLIM_, RLIMIT_, RUSAGE_ -sys/sem.h sem, SEM_ -sys/shm.h shm, SHM[A-Z], SHM_[A-Z] -sys/socket.h AF_, MSG_, PF_, SO -sys/stat.h st_, S_ -sys/statvfs.h f_, ST_ -sys/time.h fds_, it_, tv_, FD_, ITIMER_ -sys/times.h tms_ -sys/uio.h iov_, IOV_ -sys/utsname.h uts_ -sys/wait.h si_, W[A-Z], P_, - BUS_, CLD_, FPE_, ILL_, POLL_, SEGV_, SI_, TRAP_ -termios.h c_, V, I, O, TC, B[0-9] -time.h tm_ - clock_, timer_, it_, tv_, - CLOCK_, TIMER_ -ucontext.h uc_, SS_ -ulimit.h UL_ -utime.h utim_ -utmpx.h ut_ _LVL, _TIME, _PROCESS -wchar.h wcs[a-z] -wctype.h is[a-z], to[a-z] -wordexp.h we_, WRDE_ -ANY header _t diff --git a/WUR-REPORT b/WUR-REPORT deleted file mode 100644 index d997bd0..0000000 --- a/WUR-REPORT +++ /dev/null @@ -1,34 +0,0 @@ -<unistd.h>: - -lssek: Probably should be __wur but lseek(fd,SEEK_SET,0) will succeed if - the descriptor is fine. -lseek64: same - -<stdio.h>: - -setvbuf: if stream and buffer are fine and other parameters constant, - it cannot really fail. -fseek: see lseek -fseeko: likewise -fgetpos: similarly -fsetpos: likewise - - -<stdlib.h>: - -atexit: it is guaranteed that a certain number of handlers can be - registered, so some calls might need not be checked -on_exit: same -random functions: one might want to discard a number of results.
