Keyword substitution: kv
Default branch: MAIN

introduce rand_i() (libc can't change rand's seed by calling it internally)

  add x86_64 memccpy, mempcpy
  import Debian bugfixes (Christian Seiler)

fix arc4random (Lorenzo Beretta)

add getcontext and setcontext for i386 and x86_64

support clang by adding -fno-integrated-as

some cleanup

some asm string functions

  use randomness passed in ELF auxvec instead of /dev/urandom in startup
    (strace looks cleaner now)
  use ELF auxvec to implement getpagesize
  support thread local storage (w00t!!!!)
and a small cosmetic change to fgetc_unlocked

enable additional warnings
shut those warnings up :-)
try to make stdio thread-safe

add syscalls to dynamic linking

lots of new syscalls

  add strdupa and strndupa (for directfb)

support for stack gap (enable in dietfeatures.h)
support for gcc ProPolice (needs stack gap enabled)
extend WANT_NON_COMPLIANT_STRNCAT to strncpy.

profiling support (x86 only)!

fix i386 getenv (Hans Lermen)

fix signals on Alpha by emulating signal with sigaction.
fix struct termios portability problems

lots of warnings removed

optimize fread()ing large blocks.

the md5 code on little endian ARM produced unaligned accesses when
passed unaligned pointers.
fix t.c warning with openpty

more EINTR fixes in openpty (ioctl can return EINTR, too)
ttyname was broken (readlink does not \0-terminate, so we have to)

shave off a few bytes from parselib by removing the exit code from
__prepare_parse, which was not used anyway because you could see whether
it worked by looking at the struct state afterwards.  Uwe Ohse noticed
this.
Also, fix asprintf, which relied on vsnprintf to not write anything when
passed a NULL pointer.  This was no longer the case after Olaf redid the
printf engine.

fix typo in ARM unified syscall,
work around gcc 3 warnings caused by gcc internal wrong prototypes,
make malloc(0) return NULL again,
fix cfgetospeed (used wrong field of struct termios, oops!)

several bug fixes from Uwe Ohse.

moved _exit into the unified syscall in x86.

__dtostr was really disgusting.
It still is, but it sucks in different ways now.
We really need to __dtostr, one for %g and one for %f.
The new version won't do scientific notation at all, but it's better
than the previous version anyway.

a wrong comparison in gmtime_r caused the time functions to convert Jan
1 to Dec 32 (oops!).

implement alarm as syscall, not as setitimer wrapper.

make glob.h include sys/types.h
remove broken x86 strtod.S ("30" returned 10.0)

res_query did not initialize last

fix make install for dynamic loader.
It wrote to diet.so.conf instead of diet.ld.conf

fixes from the train journey ;)

Oops, Frank Klemm's fixes to strftime apparently completely broke it and
nobody noticed.  Is that a good sign (because nobody uses this crap
function) or a bad sign?

several changes to make vs_ftpd compile.

work around more brain damage in hwclock and kbd.

kludge around GNU tar problems

add more tests, prototype if_nameindex and if_freenameindex

fix getpass

fix adjtime

make dnscruft2 use res_query and not just res_mkquery

rewrite getproto* to parselib (and add ..._r versions)

rewrite getserv*, provide ..._r versions.

replace entlib with a more generic parselib.  Convert entlib using code
to parselib.  TODO: convert /etc/hosts and /etc/services parsers to
parselib.

use __NR__newselect instead of __NR_select ("oldselect", says strace) on
arm.

*scanf did not \0-terminate %[...]

uh, the dns routines needed a little more LARTing

add NO_DATA message.

add assembly bsearch from Wouter van Kleunen.

more DNS error signalling

DNS error handling!

test for olaf

clean up even more weak and symbols and make more local symbols static

a few more Frank Klemm fixes.

add __write1 and __write2 (idea by Frank Klemm)

add 32-bit uid syscalls (and prototypes).
We still need backwards compatibility wrappers.

mhh, forgot to update md5asm.S?!

x86 strchr did not declare weak alias for "index".
scanf did not accept %02x
scanf did not return EOF if it hit EOF without scanning anything.

add md5 crypt

memchr returned -1, not 0

add adjtimex

add memmem

a typo in strcmp fix rendered it dysfunctional

add several more x86 assembly functions to shave off a few bytes here
and there.

rewrite x86 strcmp and strncmp (the submitted functions were buggy).

even more x86 assembly crap

The memcpy the guy sent me copied the wrong way

oops, bug in memchr.

ugh, fix fflush lseek bug and made limits.h more mutt friendly.

fix -ansi -pendantic errors and warnings about inline and long long.

fix three stdio bugs

same fix as for gethostbyname_r

umount/umount2 were declared twice and gethostbyname_r did not check the
aliases from /etc/hosts.

oops, mkdtemp was b0rken.

add getopt_long_only and rework getopt and getopt_long so they
understand optidx=0 (which is in violation of susv2 but some b0rken
BSD crapware does it anyway).  Did I mention that BSD sucks?  A lot?

add initial iconv implementation that can convert iso-8859-1 <-> UTF-8
<-> UCS-4.

tweaky tweaks Frank Klemm is sneaky...

more i386 trickery from Frank Klemm.

smaller clone from Frank Klemm

add tmpnam and remove warning from vprintf

fix a lot of bugs ;)

Smaller strcasecmp and strncasecmp implementations from Frank Klemm,
slightly smaller mktime and gmtime, and x86 assembler implementation for
strtod from Frank Klemm.

More assembly tweaks from Frank Klemm (and more printf brokenness by me)

yet another printf bug

fix printf.
longjmp references __sigprocmask (it's sigprocmask now)

ugh!  floating point printf stinks!

a few stdio fixes and typo removal

More functions and optimizations from Frank Klemm

be friendlier to busybox

fix bugs in fwrite as Uwe pointed out.

Fix the bugs in fgets that Uwe found.

fix ghastly bug in getservent (allowed only isalpha() in aliases, so
"pop-3" was considered a parse error)

add dirname, basename.

oops, signedness snafu in isalpha

endhostent fix and sparc/syscalls.h had a syntax error.

add openpty (for sshd), make gethostbyname2 actually honor
WANT_ETC_HOSTS, make inet_pton accept "::" as IPv6 address (oops).

stdio should not include unistd.h.  Otherwise configure from openssh
thinks that getpgrp takes an argument.

it's ttyname.o, not tty.o (in the Makefile dependencies)

allow tabs instead of spaces in /etc/fstab

call endhostent()

/etc/hosts support!

add overflow handling for strtol and strtoul.

mntent is fscked ;)

ugh, touched all stdio and ripped out the non-ungetc and unbuffered
modes.  Did some ELF weak symbol trickery to make `puts("foo")' not
reference the whole stdio crap.

time zone parser now sets tzname

update mkstemp and mkdtemp tests in t.c

add mkdtemp

system signalling madness, part II

popen did not set close-on-exec flag on fd, could leak fd on malloc
error in fdopen, system did not ignore SIGCHLD and thus had a potential
wait() race.

mention Uwe in THANKS

cleanse more linux kernel headers, fix bugs in ttyname and realpath,
add linker warnings to gethostby{name,name2,addr} and share memory
leakage.

consolidate two buffers.

word delimiters in the regex library looked for spaces instead of
non-word characters (i.e. "," did not delimit a word)

try to make assert work with ancient gcc versions.

make t.c compile again ;)

only the first search domain from /etc/resolv.conf was actually used.

make stdarg work on powerpc.

even more clean-up

add an errno in libpthread that will display a prominent linker warning
when used.

try to work around Linux kernel IPv6 brokenness,
use $(CC) instead of gcc for compile and load targets in Makefile.

a ton of warnings fixed ;)

add %h to vsnprintf.

regular expression fix for matching x* in the case without any x.

fix fnmatch (but related to * and FNM_PATHNAME)

res_query and res_search (!!)

regexec offsets fix.

fread of 0 bytes returned 1, not 0.

break strncat even more in the default case (copy n bytes plus \0, not n
bytes including \0).

new POSIX getopt (i.e. no argv permutation)

add sys/sysmacros.h

long long support (optional) for printf (%lld)

atoi did not skip leading spaces.

vsnprintf %X now uses upper case (again)

duh, fix stupid flushing bug in fputc for non-buffered output (i.e.
stderr)

one more ooooops in the DNS routines.

oooooooops

add getserv*.
the dns routines can now optionally (WANT_FULL_RESOLV_CONF) try
to append the different domains from /etc/resolv.conf.

RLIM_INFINITY from the kernel is bogus.  Thanks, Chris Siebenmann for
sending a patch!

fix FD_* macros on Alpha (man do the kernel headers suck!)

cosmetic changes and signal testing

argh, exit code check was broken.

shuffled getopt_long and getopt declarations.

misc scanf fixes

fix a scanf bug

The "::" case was written as ":".

hass hass hass

argh, everything is broken around me! ;)

fix bugs in getaddrinfo.

fix mmap (oops)

paaaarty!  getaddrinfo is there! ;)

I misinterpreted "width".

distinguish between '%f' and '%g'.

evil hack for 0 in __dtostr.

setfsuid, setfsgid syscalls.

revert set_errno to weak errno=

difftime added.

add scandir.

REG_ICASE was b0rken.

new configuration option: make strsep conform to glibc (and what openssh
expects) instead of what the man page says.  ARGH!!!

fix off-by-one error in bsearch

ungetc data was not initialized in stdio FILEs.

add ioperm, flock prototype, <sys/io.h>.

make the non-compliant behaviour of strncat configurable in
dietfeatures.h

add *abs.

fix mktemp linker warning (maybe it should blink, too?) and fread and
fwrite for sockets.

add clock

fix fnmatch even more ;)

fix DNS decompression.

oops, vfprintf would always print an empty string.

msgsnd was b0rken.

add a comment about how fast this regex implementation is compared to
the glibc one.

add realpath and wrap getcwd (syscall returns length, not buf).

much improved regular expressions (REG_ICASE handling, substring
handling (i.e. regex "foo" matches "blaatfoo"), REG_NOTBOL and
REG_NOTEOL handling, word start/end handling).  In short: I begin to
gain confidence in them.  Object file size: 4408 bytes.

add "%.2f" support for printf.

add setenv and execlp.

import fnmatch fix from Guillaume Cottenceau.

add getmntent, setmntent, endmntent, query_module.

remove a few warnings, add res_init.

add lseek64 with lseek fall-back mode.

fix sig*set and fwrite.  mount from util-linux now actually compiles and
works!

isxdigit was broken (typo, || instead of &&)

add "%*s" and "%*.*s" to vsnprintf.

add tzset as ELF alias

0.8 release (updated TODO, CHANGES and THANKS and made sure it compiled
on all platforms)

kludged around a little with Jeff's entlib stuff ;-}

getpwnam, getpwuid rewritten.

fixed (?) __dtostr.

add several functions to make busybox compile and partially link.

added tzfile implementation (read /etc/localtime to get time zone).
Finally, localtime() can cope with daylight saving time!

pseudo-locale support (is* are weak symbols now), fixed a bug in
getservbyname (the last alias on the line was not parsed properly), add
nice(2).

add shutdown.

mkstemp now uses not 4 but 5 bits per digit.

added mkstemp

strncat fixed.

add strftime (yuck!!!)

added prototype for sleep

update CHANGES file.

gethostbyaddr!1!!

gethostbyname can now look up CNAMEs :-(

I should go home and cure my toe instead of writing broken code today

hton*, ntoh*

add bcopy

added herrno glue, random/srandom (same as rand and srand for now),
inet_addr and inet_ntoa.

added gethostbyname (DNS only so far).  Don't look at the code, though.

add isprint.

several stdio fixes courtesy to the S-Lang test suite.

usleep fixed.
reorganized interleaved read/write seeking in stdio.

popen and pclose!  Whee!  diet libc can not link slsh (small interpreter
from S-Lang)

implement __isnan (referenced by libm.a from glibc).

implemented really crappy rand() and srand() (if you need real
randomness, use a real PRNG).  Implemented qsort() and bsearch().
For some reason, they outperform their glibc counterparts by a
surprisingly large margin _and_ are smaller.

Implemented linker warnings!  Woohoo!
Added linker warnings to a couple of dangerous or bloaty functions.

add shm*

add experimental System V semaphores implementation.

successfully reverse engineered inet_aton (look at the source, it's mind
boggling) and implemented a close approximation.

vsnprintf(0,...) estimated the length of strings with a padding width incorrectly.

fixed fread on pipes.

remove more glibc compat cruft.
They have trouble being compatible to themselves, so why should we? ;-)

implemented gmtime, gmtime_r to get rid of uClibc code.

added time conversion cruft.  Needed to link gzip.

oink oink, dumb mistake while optimizing strtoul.

made ctype functions __attribute__ ((__const__)) (gcc magic).
implemented islower, isupper, strcasecmp and strncasecmp.
added putc and putchar as macros.
#defined STDIN_FILENO, STDOUT_FILENO and STDERR_FILENO.

added trivial 7-bit tolower and toupper.

fixed stdio line buffering for stdout and stderr.

changed enum for SEEK_SET etc to #defines (caused weird link problems).

files where missing (?)
