24: platforms)
1.629 leitner 25: fix dynamic build
1.630 leitner 26: do the magic required for -fstack-protector in gcc 4.1.1 to actually

1.409 leitner 337: add sendfile64 backwards compatibility glue
1.410 leitner 338: add __attribute_dontuse__ to declare a few functions as deprecated

1.437 sanjiyan 366: Olaf: fixed a libdl ref-counter bug (Thomas Walpuski)
1.438 leitner 367: All hail to the busybox chiefs! Instead of reporting bugs they find,
368: they put a #error in their source code. Is Erik seeing the diet
369: libc as uClibc competition that needs to be squashed even with
370: unfair methods? People, if you find bugs, tell us!
371: Fixed fputc and freopen (found in busybox comments)
1.381 fefe 372:

1.352 fefe 387: fix unified x86_64 unified syscall 64-bit return value issue (Gwenole)
1.353 fefe 388: the getdents64 emulation was broken and repairing it opened a can of
389: worms. So I ripped it out. I also changed the readdir64 emulation
390: to work if there is no getdents64.
1.354 fefe 391: fix ia64 start.S (Thanks to Volker Birk for an account on his ia64 box)
1.355 fefe 392: many ia64 fixes (waitpid, nice, fork, vfork, time, utime ...)
1.356 fefe 393: More fixes from Gwenole (printf %p only printed the last 32 bits, I
394: botched the getdents64 #ifdefs, we violated the x86_64 ABI)

1.359 fefe 397: add new 2.5 syscall #defines
398: add epoll_create, epoll_ctl and epoll_wait
1.360 fefe 399: the new x86 syscall numbers exceed 255, breaking our %al optimization
400: I worked around it with conditional assembly in cpp macros. Ugh.
1.361 fefe 401: more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
402: the instruction before the syscall to be a load immediate)
403: fix fread() from a pipe (oops, tried to lseek)
1.362 fefe 404: #define _POSIX_VDISABLE in termios.h (Laurent Bercot)

1.330 fefe 430: argh, atexit fell victim to bit rot (or maybe Olaf)
1.331 fefe 431: add WANT_INET_ADDR_DNS to make gethostbyname not look up IP numbers
432: but use them to fill in the struct hostent directly.
1.332 olaf 433: signal is now a correct signal (Olaf)
1.333 fefe 434: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
435: the built-in defaults.
1.334 fefe 436: add file "SECURITY". I will document design tradeoffs that have
437: security implications there.
1.335 fefe 438: fixed regex LINEEND condition
1.336 fefe 439: add .size directive to i386 syscalls
1.337 fefe 440: shove a few more bytes off the i386 socket calls

1.308 fefe 453: 0.19:
454: current gcc cvs makes __thread a keyword (Eric Troan)

1.313 fefe 458: fix ia64 start code and unified syscall (me)
1.314 fefe 459: add sparc/strlen.S from Thomas Ogrisegg

469: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 470: add libm2.s from contrib to i386 (oops, how long has it been sitting
471: there?)
1.284 fefe 472: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 473: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 474: upcoming AMD Hammer chips!). You can't even buy the chips yet and
475: the diet libc already supports it! Amazing ;-)
476: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 477: Andre sent a patch to add ARM profiling. He says it does not work
478: yet, but it's a start.
1.287 fefe 479: added getdents64 backwards compatibility and include it in large file
480: support #defines
1.288 fefe 481: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)
1.289 fefe 482: ftell did not take ungetc into account (Kevin Ryde through Debian).

1.281 fefe 508:
1.264 fefe 509: 0.17:
1.265 fefe 510: fix several bugs in getservent_r
1.266 fefe 511: Gunnar Ritter reported the following:
512: moved tcgetpgrp and tcsetpgrp to unistd.h
513: adjusted lstat->lstat64 #define to make it work with function pointers
514: move __dietlibc__ #define from features.h to diet
1.267 fefe 515: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
516: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 517: Thomas also sent me profiling support (so far only on x86, but
518: profiling/PORTING describes what needs to be done for other
519: architectures)!
1.272 fefe 520: add contrib/dprof.c, also from Thomas.
1.269 fefe 521: Andreas Krennmair sent a patch to add the BSD regex interface to
522: libcompat
1.271 fefe 523: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 524: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 525: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 526: abort did not flush all stdio streams
1.277 fefe 527: fix some nasty regular expression bugs
528: write a stupid malloc checker (contrib/debug-realloc.c) to help me
529: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 530: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 531: fix DNS domain search
1.280 fefe 532: i386 memccpy exchanged esi and edi :-( I should do more checks before
533: accepting external code...
1.264 fefe 534:
1.244 fefe 535: 0.16:
536: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 537: Andre found two very embarassing bugs in my four lines of md5 glue.
538: I need to get more sleep.
1.247 fefe 539: Thanks Ogrisegg found that ptrace does not work as documented and
540: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 541: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
542: fix ptrace.h for S/390 and ARM
543: provide a PORTING document so we don't lose track of which file need
544: to be touched to port the diet libc to a new platform.
1.249 fefe 545: remove a few warnings
546: provide a prototype for usleep.
1.250 fefe 547: make __dtostr work on ARM by using long instead of long long.
548: Idea by Dirk Engling.
1.251 fefe 549: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 550: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 551: Kurt Garloff sent in patches to
552: fix struct termios on non-x86 architectures
1.254 fefe 553: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
554: create libcompat.a (and move daemon to it)
1.255 fefe 555: add getdelim and getline
556: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 557: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 558: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 559: Hans Lermen fixed i386/getenv.S
1.259 fefe 560: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 561: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
562: Macodiseas)
1.261 fefe 563: sys/ipc.h now includes sys/types.h
1.262 olaf 564: Olaf: started to make the sparc64 port

1.244 fefe 566:
1.224 fefe 567: 0.15:
1.225 fefe 568: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 569: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 570: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
571: thread-safe!
1.228 fefe 572: remove vfork and add alarm to dynamic syscalls.
573: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 574: The MD5 code generated unaligned accesses when passed an unaligned
575: pointer on little endian ARM and MIPS.
576: MIPS unified syscall didn't compile anymore.
577: Put up new mipsel target to cross compile for little endian mips.
578: The mips target will again explicitly set endianness to big endian.
579: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 580: Duh, when we removed return0, we broke tzset when the time zone parser
581: was disabled. Uwe Ohse noticed this. Thanks!
582: Fix gethostbyname to match host names case insensitively in /etc/hosts.
583: Oops, this was reported 6 weeks ago but I overlooked the email.
584: Thanks, Denis Rachal!
1.231 fefe 585: vsnprintf's zero termination was broken.
1.233 fefe 586: Uwe Ohse found a few more bugs:
587: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
588: does it correctly.
589: Make inet_aton use strtoul instead of strtol
590: fdopen would close the file descriptor if it could not malloc the
591: buffer.
592: strftime updates.
593: Make _FILE_OFFSET_BITS includes -Wundef clean
594: Andre found a typo in endian.h for big endian mips
1.234 fefe 595: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 596: strstr(whatever,"") returned NULL, not whatever. Found by a new test
597: suite entry for strstr that I wrote.
1.245 fefe 598: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 599: add <asm/sigcontext.h> for profiling support.
600: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 601: an i386 assembler getenv implementation (roughly half the size)
602: add grantpt, ptsname, unlockpt
1.236 fefe 603: add a getenv test suite entry.
1.238 fefe 604: Andre contributed an ARM assembler md5 implementation and he fixed mmap
605: on ARM.
606: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 607: getservent_r did not parse lines without aliases. Thanks, Jaroslav
608: Macodiseas!
1.240 fefe 609: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 610: removed annoying -Wconversion gcc switch
1.242 fefe 611: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 612: Kurt Garloff sent these diffs:
613: add fdatasync (and make it a pthread cancellation point)
614: numerous alpha issues, like using .quad instead of .long for
615: offsets, change strip to -strip in Makefile (so a failing strip does
616: not abort the make), try to be more friendly to the gcc 2.96 that
617: SuSE 7.1 AXP ships with.
1.224 fefe 618:
1.209 fefe 619: 0.14:
1.224 fefe 620: fix brk again (missing __brk, trivial oversight)
1.210 fefe 621: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
622: Thomas Ogrisegg!
1.211 fefe 623: Thomas also contributed a PA-RISC port including testandset, so
624: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 625: made the fake locale more believable.
626: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 627: moved _exit into the unified syscall on x86.
1.214 fefe 628: Uwe Ohse found many more bugs:
629: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
630: liblatin1 was more or less completely broken if you gave it chars as
631: arguments, not ints (signedness). execvp had a buffer overflow in
632: case a PATH element exceeded PATH_MAX, but it's not a security
633: problem since setuid programs need to set their path to some known
634: value anyway.
1.219 fefe 635: hasmntopt did not work with foo=bar style options
1.217 fefe 636: Uwe also improved ftw's stack usage.
1.214 fefe 637: Put movl instead of popl rationale in comment in i386/unified.S since
638: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 639: I discovered __attribute__((malloc)) and started using it. For gcc 3,
640: it improves the optimizer when functions return malloced pointers.
1.216 fefe 641: Steven Rostedt pointed out that my setvbuf was broken with regard to
642: size==0 and sent a patch to fix it.
1.218 fefe 643: Thomas Ogrisegg made setenv smaller.
1.220 olaf 644: Olaf: implemented the parisc clone and an atomic testandset, modified the
645: libpthread to respect the parisc UPgrowing stack. still non functional,
646: because the unified syscall uses errno :(
1.221 fefe 647: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 648: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
649: don't write anything which was no longer the case. It also
650: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 651: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 652:
1.193 fefe 653: 0.13:
1.194 fefe 654: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 655: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 656: Olaf: port to S/390!
1.463 leitner 657: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 658: res_query did not initialize last
1.199 fefe 659: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 660: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 661: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 662: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 663: rewrote __dtostr (it also has one more argument now)
1.205 fefe 664: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 665: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
666: fix strncat for the case where n == 0 (security implications?)
667: fix bsearch (it didn't find the very last element in the array, same
668: bug in both the C and the i386 assembly version).
1.205 fefe 669: fixed FNM_PATHNAME in fnmatch
1.204 fefe 670: fix brk (the syscall was documented incorrectly in the Linux man page)
671: Thanks, Thomas Ogrisegg!
1.205 fefe 672: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 673: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 674: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 675:
1.164 fefe 676: 0.12:
677: more contributions from Frank Klemm.
1.165 fefe 678: iconv can now do UCS-2, too.
1.167 fefe 679: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 680: Lots of bug fixes, and several more i386 specific versions of common
681: routines to make them smaller.
1.168 fefe 682: add memmem (a GNU extension that looks useful)
1.170 fefe 683: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 684: add pivot_root syscall, %n for *scanf.
1.169 fefe 685: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 686: add Frank Klemm's optimized md5
1.172 fefe 687: add -Os option to diet (see diet.1).
1.173 fefe 688: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 689: add 32-bit uid/gid syscalls.
1.175 fefe 690: add rand48 (thanks, Johannes Kloos)
1.176 fefe 691: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 692: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
693: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
694: fix gethostent alias list termination. Major oops.
1.178 fefe 695: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 696: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 697: DNS will now properly signal errors and set h_errno.
698: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 699: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
700: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
701: external reference to a symbol that is only in the diet libc. So,
702: when you accidentally link a diet libc compiled object file against
703: glibc, the linker will barf. This will bloat your object files, but
704: you can remove all the references with "strip -R .note" from
705: the binaries in the end (which you should do anyway).
1.182 fefe 706: fix ARM unified syscall (select did not work).
1.183 fefe 707: add getpwent_r ala glibc and replace getpwent
708: do the same for getgrent and getspent
709: remove entlib (new code is smaller)
1.184 fefe 710: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 711: add getpwnam_r and getpwuid_r
1.186 fefe 712: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 713: Olaf muddled with the dynamic linker. It's a clean-room
714: implementation in the sense that it once worked for Olaf in a clean
715: room ;)
1.188 fefe 716: add if_nameindex and if_freenameindex.
717: fixed arm unified syscalls to work with current binutils (; is no
718: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 719: changed all st_[cma]time types to signed long so comparisons against
720: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 721: fixed two bugs regarding ungetc.
722: add getusershell, setusershell, endusershell (for vs_ftpd)
723: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 724: fixed strftime (was completely hosed)
1.192 fefe 725: added real make install target
1.164 fefe 726:
1.115 fefe 727: 0.11:
728: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 729: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 730: add floor, ceil and memchr prototypes.
731: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 732: cleaner errno vs __errno_location handling
733: add placeholder iconv (iconv_open will always return EINVAL)
734: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
735: initialization of getaddrinfo.
1.119 fefe 736: fix vsnprintf %X (printed lower case)
1.120 fefe 737: I wrote a new getopt. It appears to actually work (it is POSIX
738: compliant, it does not sort argv like the GNU version) and is only
739: a little over 300 bytes on x86.
1.121 fefe 740: Guillaume Cottenceau just wrote me that strncat should be even more
741: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 742: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 743: Fix regexec offset return. autoconf now believes that diet libc has
744: POSIX regular expressions.
1.123 fefe 745: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 746: Fix regular expression match for x* when there is no x at all.
1.125 fefe 747: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 748: Add %h to vsnprintf.
1.127 fefe 749: Add FAQ.
1.128 fefe 750: Make %h work for signed numbers and add %hh to vsnprintf.
751: initgroups ignored the group argument :-(
752: remove printf references and nested functions from glob.
1.129 fefe 753: added an errno in libpthread that will display a prominent linker
754: warning.
1.131 fefe 755: started getting rid of kernel headers. Big task! :-(
1.130 fefe 756: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 757: Olaf: added a lot of code in libdl (not yet complete), changed the
758: startup code to make it work with his libdl and ld.so (needs still work
759: too)
1.134 fefe 760: __dns_readstartfiles only took the first domain or search path.
761: Thanks, Anthony de Boer
1.133 olaf 762: Olaf: added clone and a new unified_syscall for PowerPC
763: also dynlinker is now available (i386 only at this time)
1.135 fefe 764: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 765: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 766: fixed word delimiters in regex (they looked for space, i.e. "," did
767: not work as delimiter)
1.138 fefe 768: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 769: added mkdtemp.
1.142 fefe 770: Uwe Ohse reported all of the following bugs:
771: ttyname should return 0 if !isatty.
772: realpath returns NULL if "." cannot be opened
773: putenv erroneously accepted (and mishandled) entries without "=".
774: popen returned 255 instead of 127 if /bin/sh could not be run.
775: fgetc did not set the internal EOF indicator on EOF.
776: bsearch contained an assumption about integer arithmetic overflow
777: behavior.
778: system did not set SIGCHLD and thus contained a race.
779: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 780: daemon did not check whether open returns an fd below 3
781: perror did not save errno.
1.144 olaf 782: Olaf: Peter Jones reported some problems with perror; strerror had the
783: same problem.
784: Peter also posted a patch to atexit/exit. With some modifications it is
785: now implemented.
1.145 fefe 786: Unbuffered stdio and ungetc can no longer be disabled. I will try to
787: implement part of it using ELF weak symbols.
1.146 fefe 788: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 789: Added overflow handling for strtoul and strtol.
1.149 fefe 790: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
791: it before falling back to DNS if enabled.
1.150 fefe 792: Added a littie backwards compatibility cruft for gpm (man, do these
793: sources stink!)
1.151 fefe 794: Added openpty.
1.152 fefe 795: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 796: Fix fseek return value.
1.155 fefe 797: Add dirname and basename.
1.156 fefe 798: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 799: Fixed getservent (did not allow _ and - in the aliases).
800: Thanks, Oden Eriksson
1.158 fefe 801: Added a float.h so configure believes we have ANSI header files.
802: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 803: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 804: scanf and printf function implementations
1.160 fefe 805: Imported a few more functions and optimizations from Frank Klemm (he
806: also rewrote dtostr to have more precision)
1.161 olaf 807: Olaf: checked in a new sig* function family (based on rt_sig*).
808: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 809: Made rudimentary iconv that can convert back and forth between
810: iso-8859-1, utf-8 and ucs-4 (for debugging).
811: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 812:
1.74 fefe 813: 0.10:
814: update getpagesize.
815: add personality.
1.75 fefe 816: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 817: add putchar (apparently arm-linux-gcc will substitute printf("\n")
818: with putchar('\n') behind your back...?!
1.77 fefe 819: import include/scsi/ from glibc.
1.78 fefe 820: add iopl.
1.80 fefe 821: add execl and sigdelset prototypes.
822: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 823: add RPC headers (no code yet).
1.82 fefe 824: add mlockall, munlockall
1.83 fefe 825: make "diet gcc foo.c" work.
826: added Sun RPC code and removed as many warnings as possible in a
827: heroic act of self-mutilation.
828: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 829: added getpass. mount from util-linux actually compiles now!
830: fix the sig*set routines. mount actually works now *bg*
831: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 832: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 833: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 834: add res_init.
835: add asprintf (ugh, what an ugly function).
1.89 fefe 836: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 837: add ut_name alias to ut_host in struct utmp.
838: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 839: add sysinfo, recvmsg, sendmsg.
1.93 fefe 840: add endmntent, getmntent, setmntent.
1.94 fefe 841: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 842: add setenv.
843: remove __restrict from mntent.h, add __restrict__ removal alias for
844: older gcc versions in sys/cdefs.h.
845: add rlim_t, sig_atomic_t declarations.
846: add sigsetjmp #define for __sigsetjmp (oops).
847: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 848: add a gruesome hack to printf floating point to accept %f and kludge
849: together support for %.2f. Don't look at the code, please!
1.98 fefe 850: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 851: imported fix for entlib by Jeff Garzik.
1.100 fefe 852: add glob implementation from Guillaume Cottenceau (Thanks!!)
853: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 854: add REG_ICASE and word start/end handling to my regular expressions.
855: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 856: wrap getcwd to comply to man page (the syscall returns the number of
857: bytes, not the buffer)
858: add realpath.
1.103 fefe 859: fix vfprintf.
1.104 fefe 860: fix *scanf %s zero termination.
861: add abs, labs, llabs.
1.105 fefe 862: add <sys/io.h>, ioperm syscall.
863: add flock to <sys/file.h>
1.106 fefe 864: fixes to bsearch and the regular expressions.
1.107 fefe 865: add fake herror.
1.108 fefe 866: add scandir and alphasort.
1.109 fefe 867: add killpg
1.110 fefe 868: implemented a gross hack to make libpthread compile when
869: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 870: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 871: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 872: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
873: for sending a patch.
1.114 fefe 874: add getserv*.
875: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
876: "search" from resolv.conf.
1.74 fefe 877:
1.73 fefe 878: 0.9:
1.65 fefe 879: fixed initgroups (oops)
1.66 fefe 880: Cleanup appending file open for stdio (thanks, James Antill)
881: imported vfprintf fix from James Antill.
1.67 fefe 882: add fnmatch
883: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 884: Olaf added character classes to *scanf.
1.69 fefe 885: Put object and library files into a separate directory (bin-$ARCH).
886: Add "cross" make target to make all architectures.
887: Add "diet" program and man page.
1.70 fefe 888: Add getgrnam, getgrgid
1.71 fefe 889: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 890: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 891:
1.64 fefe 892: 0.8:
1.34 fefe 893: vsnprintf(0,...) estimated the length of strings with a padding width
894: incorrectly.
1.35 fefe 895: new reboot() from Olaf.
1.36 fefe 896: added prototypes for getsockopt and setsockopt.
1.39 fefe 897: added experimental sem* and shm*
1.38 fefe 898: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 899: added setvbuf (only changes mode, not buffer)
1.41 fefe 900: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
901: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 902: added qsort() and bsearch(). Benchmark on 1000 random ints:
903: glibc: 679414 cycles qsort and 3352 cycles bsearch
904: diet libc: 300010 cycles qsort, 553 cycles bsearch
905: I have no idea why glibc is so slow.
1.43 fefe 906: added __isnan (references by libm.a from glibc).
907: added popen() and pclose(). Now the diet libc can link slsh (from
908: S-Lang!)
1.44 fefe 909: corrected usleep. It was more of an msleep until now.
1.45 fefe 910: corrected __dtostr (it looped when trying to format "0.0").
911: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 912: added ungetc (does it work?)
1.47 fefe 913: added inet_aton (yuck!)
1.50 fefe 914: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 915: added h_errno and __h_errno_location
916: added inet_ntoa
1.49 fefe 917: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 918: add bcopy, index, rindex macros
919: add isgraph and isxdigit
1.52 fefe 920: add strftime (ugh!!!)
1.53 olaf 921: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 922: Jeff Garzik contributed a spec file. I put it in contrib and hope
923: everbody knows what to do with it...
924: Olaf checked in a ton of libpthread stuff.
1.55 fefe 925: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 926: add large file backwards compatibility support (so gzip will run on
927: kernel 2.2 and 2.0)
1.57 fefe 928: added shutdown
1.58 fefe 929: added nice
930: added pseudo-locale support for is* (they are now weak aliases,
931: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
932: overwrite the default is* functions.
1.59 fefe 933: added liblatin1.a
1.60 fefe 934: added tzfile implementation (does it work for anyone else?)
1.61 fefe 935: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 936: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
937: Thanks!
1.63 fefe 938: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 939:
1.21 fefe 940: 0.7.2:
941: added several prototypes to already implemented functions and
942: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 943: added prototypes for process group and dup syscalls. Thanks to
944: Abraham again. He also contributed an implementation for daemon(),
945: an ugly BSD hack. I decided to diversify the lib/ directory a
946: little and now created a libugly/ directory for stuff like system()
947: and daemon() ;-)
948: added libstdio and moved all that stdio crap from lib/ there. The
949: idea is to start separating now what we will separate for shared
950: libraries anyway.
1.26 fefe 951: optimized x86 unified-syscall by Olaf.
1.27 fefe 952: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
953: limits.h instead)
954: added remove.c and enough cruft to limits.h to make it compile lzo,
955: lzop and bzip2.
1.28 fefe 956: added mktime, asctime_r, asctime and ctime (needed for gzip).
957: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 958: format some day (man tzfile, ugh!) :-(
1.29 fefe 959: added unlink prototype to unistd.h.
960: added gmtime and gmtime_r.
1.31 fefe 961: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 962: removed readdir glibc compatibility cruft.
1.31 fefe 963: removed stat glibc compatibility cruft.
1.32 fefe 964: oops, my fread was broken for pipes.
1.33 fefe 965: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 966:
1.9 fefe 967: 0.7.1:
1.11 fefe 968: optimized away the static arrays from __ltostr and __lltostr.
969: optimized away the static arrays (and more!) from strtoul and strtoull.
970: added system (by Olaf).
1.12 fefe 971: added tolower and toupper
1.13 fefe 972: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 973: added clone for mips (by Olaf).
974: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 975: added pause for all (by Olaf).
1.17 fefe 976: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 977: added isupper and islower.
978: added putc and putchar as macros.
1.17 fefe 979: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
980: insightful discussions and patches I partially used for the last three)
1.18 fefe 981: added getpriority and setpriority (also by Abraham)
1.19 fefe 982: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 983: oi, setjmp and longjmp were broken on other platforms, too!
984: Thanks to Sébastien Côté for reporting this.
1.9 fefe 985:
986: 0.7:
1.6 olaf 987: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 988: Initial dynamic loading glue for i386, also by Olaf.
989: We don't have a dynamic loader yet, so this is not yet usable.
990: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
991: vsprintf, writev, all by Olaf.
1.2 fefe 992: imported readdir fix from Guillaume. Mhh, can the kernel interface
993: really be this broken?
1.3 fefe 994: Found a kludgy way to detect whether the kernel includes define struct
995: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
996: not work for you, please tell me!
1.4 fefe 997: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 998: Fixed stdio line buffering. The code was already there but I forgot
999: to mark stdio and stdout as line buffered. This should really be
1000: done dynamically using isatty, though.
1.8 fefe 1001: Removed superfluous "if (1)" in execvp.c
1.1 cvs 1002:
1003: 0.6.14:
1004: *scanf did not append the 0 byte for %s.
1005: added creat and changed creat to call open directly instead of open64.
1006: did for fread what 0.6.10 did for fwrite.
1007: repaired buffered stdio a little (line buffering is still not
1008: supported).
1009: [All of these bugs have been reported by Guillaume. Thanks!]
1010: added __pure__ to strchr and strrchr in <string.h>
1011:
1012: 0.6.13:
1013: included COPYING to make clear that the diet libc is covered by the
1014: GNU General Public License (and _not_ the LGPL). That means that
1015: you need to obtain a license from me if you want to use the diet
1016: libc in a proprietary program that you want to distribute.
1017: The x86 unified syscall swapped arguments #4 and #5 and noone
1018: noticed until now! Thanks to Guillaume Cottenceau for reporting
1019: this!
1020: The malloc had a subtle bug with small allocations that could cause
1021: segfault. Guillaume reported it, Olaf fixed it.
1022:
1023: 0.6.12:
1024: added assert, statfs and fstatfs
1025: added include/net/if.h so fget compiles again.
1026:
1027: 0.6.11:
1028: added putenv.
1029:
1030: 0.6.10:
1031: fixed fwrite. It returned the number of bytes written, not the number
1032: of records. Thanks to Albert D. Cahalan for pointing this out.
1033: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
1034: added brk and sbrk. harold@nb.com.sg made me do it.
1035:
1036: 0.6.9:
1037: fixed execvp not to return on ENOENT
1038: did for {open|read|close|seek|tell}dir what I did for stat before.
1039: The glibc compatibility part is currently non-functional.
1040: fixed white space handling in sscanf " (" would not match " (".
1041: fixed printf to accept 'l' flag.
1042: fixed getpwuid (ignored last line)
1043:
1044: 0.6.8:
1045: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
1046: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
1047: added strlcpy and strlcat from OpenBSD.
1048: added stat64, fstat64 and lstat64.
1049: added endian.h and made ending of strlen.c endianness-aware
1050: added string routines size tweak to dietfeatures.h. Most of the
1051: string routines have been unrolled. This is up to three times as
1052: fast but creates up to three times larger code. Now you can disable
1053: the unrolling.
1054: added sendfile.
1055: I also added pread. It works on x86 and sparc but not on ppc and mips.
1056: I have no idea what's going on. strace disagrees with the kernel.
1057: Can anyone help? I asked the Linux kernel mailing list for help, too.
1058: added a few aliases of the type __libc_open for open. nm on
1059: libpthreads.so indicates that we will need them.
1060:
1061: 0.6.7:
1062: the sources now compile without warnings with -Wall.
1063: printf now prints "(null)" when %s is passed NULL. This can be
1064: removed with WANT_NULL_PRINTF in dietfeatures.h
1065: added vfprintf, execl, ttyname.
1066: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
1067: __dietfstat so they can use the normal kernel struct stat.
1068: stat, lstat and fstat are now C wrappers that convert to the glibc
1069: struct stat. So we can avoid that overhead for programs that use
1070: dietlibc headers.
1071:
1072: 0.6.6:
1073: changed the Makefiles so you can now set CFLAGS on the command line
1074: added memccmp (analogous to memccpy) and strncmp.
1075: Olaf fixed another bug in the sparc unified syscall.
1076: Paul Clifford contributed a C version of his strlen.S that is much
1077: more efficient than the previous strlen on all platforms! It also
1078: looks like technology from Roswell. ;-}
1079: added a "real" stdio. Well, almost. Please contribute!
1080: added dietfeatures.h so you can remove features you don't need.
1081: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
1082: stdio now works with simple programs and minigzip from libz.
1083: stdio uses some major trickery to avoid linking the stdio, stderr and
1084: stdout (and reserving space for them) when they are not used.
1085:
1086: 0.6.5:
1087: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
1088: most of them bugs in the new header files, but also missing sigset
1089: functions.
1090: Paul Clifford contributed an assembly strlen.S for ARM and fixed
1091: several bugs.
1092: Fixed ppc/setjmp and mips/pipe.
1093: Olaf contributed a new sparc unified syscall.
1094:
1095: 0.6.4:
1096: declared is* static inline in getservent.
1097: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
1098: changed strlen to return 0 when passed NULL.
1099: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1100: Scientist who actually implemented this without access to a MIPS
1101: box, just from reading the architecture manual. And it worked out
1102: of the box.
1103: started a set of system includes, mainly so that I can use lcc and
1104: my alpha-linux cross compiler (which is unable to cross-compile
1105: glibc). diet libc can now be compiled without any include files
1106: from a normal libc. The includes do declare more than diet libc
1107: currently delivers and they are still far from complete for real
1108: applications.
1109: I will only add assembly versions that are smaller _and_ faster than
1110: the C version. Larger routines are only accepted if they are called
1111: very often and are substantially faster.
1112: added i386 assembly strchr, which is smaller and faster than the old
1113: version. It is, however, larger than the version contributed by
1114: proton (thanks, anyway).
1115: added i386 strlen (31% faster, 14% smaller)
1116: "make t" will now create a map file called "mapfile".
1117:
1118: 0.6.3:
1119: added sys_errlist, strerror and perror
1120: added isblank
1121: added atol
1122:
1123: 0.6.2:
1124: mmap for ARM didn't compile. Thanks, Paul!
1125:
1126: 0.6.1:
1127: split mmap into the architecture specific subdirectories.
1128: getenv now copes with environ==NULL, thanks Paul Clifford.
1129: Paul also contributed a smaller ARM startup code.
1130:
1131: 0.6:
1132: strcat returned the wrong result. Thanks, Dietz Pröpper.
1133: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1134: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1135: __dtostr does not work (I have no idea why!)
1136: The MIPS port now uses (much smaller) non-PIC code. That means that
1137: the applications you link against diet libc also have to be compiled
1138: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1139: Thanks to Ralf Bächle for helping me with this!
1140: I made subdirectories for the architectures and use VPATH to override
1141: VPATH so that make finds the source file automatically. That should
1142: simplify the sources greatly.
1143: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1144: ARM and MIPS now also have setjmp and longjmp
1145: "compile" and "load" are now make targets. Use them for djb programs.
1146: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1147: Again, contributed from Olaf. Great work!
1148:
1149: 0.5.12:
1150: printf also does signed numbers.
1151: If you don't use atexit, dietlibc now does not link exit, only _exit.
1152: *printf now correctly returns the number of bytes written.
1153: Olaf contributed experimental sscanf and vsscanf implementations.
1154: If passed NULL as buffer, snprintf will not write anything but still
1155: return the number of bytes it would have written.
1156: Initial MIPS port! (Oh, the agony!)
1157: No setjmp and longjmp support yet! Please contribute!
1158: I even implemented unified syscalls for MIPS. Still, MIPS code is
1159: almost twice the size of SPARC code. If anyone knows why: please
1160: tell me!
1161:
1162: 0.5.11:
1163: I implemented new unified syscalls for x86, sparc and ppc, this time based
1164: on .s files and not .c files, and I moved the syscalls into
1165: subdirectores to clean the dietlibc sources up a little.
1166: A binary consisting of printf("%s is %d\n","olaf",23) is now
1167: 2864 bytes on sparc
1168: 2488 bytes on intel
1169: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1170: to make a few more applications work.
1171: Olaf Dreesen also implemented some unified syscall stuff for x86.
1172: He discovered that with our unified syscall interface it actually
1173: costs <10 bytes total to make all system calls thread safe!
1174: I implemented atexit() (can register up to 4 callbacks).
1175: I implemented strtod and __dtostr (the opposite). Now we can add
1176: floating point support to vsnprintf and sscanf!
1177:
1178: 0.5.10:
1179: I actually saw that I can not only merge the errno handling code of
1180: the system calls on x86, I can also merge the rest (including the
1181: arguments) except for setting the system call number. All those
1182: system calls are now just a jump to a unified system call handler.
1183: I got rid of x86openclose again. The savings are substantial:
1184: chown from embutils went from 7664 to 7184 bytes!
1185: If I'd move the system call wrappers to assembly language, I could
1186: even reduce the alignment (does not matter since it's just a jump
1187: anyway) and get rid of the "ret" behind each jump (one byte per
1188: system call!)
1189:
1190: 0.5.9:
1191: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1192: fixed strdup
1193: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1194: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1195: (no signed integers, only strings and unsigned integers (but
1196: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1197: that code must be wonderful, I don't understand it at all *bg*)
1198: Olaf's printf does understand padding like in "%08d" and "%8d" and
1199: automatically pads pointers with '0'.
1200: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1201: Thanks to proton for inspiration on this.
1202: The new x86 start code also does not reference exit any more, thus saving
1203: 64 bytes for executables that don't call exit explicitly.
1204: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1205: Moved errno and environ to start.S, saving no byte binary size but
1206: speeding up compilation and slightly shortening dietlibc.a ;-)
1207: For x86: joined open and close into one assembler file, sharing the
1208: errno handling. This is a feasibility test and it actually saves a
1209: few bytes. I think I will reimplement the _syscall[1-6] macros on
1210: all platforms now to share the errno handling code for them.
1211:
1212: 0.5.8:
1213: fixed strchr to be able to look for 0.
1214:
1215: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1216: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1217: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1218: contributed by Olaf Dreesen)
1219:
1220: added execvp, getcwd
1221:
1222: fixed __xmknod
1223:
1224: Note: can it be that the ftw interface really is so broken that I
1225: cannot implement it without having to implement some searching data
1226: structure? I included an experimental ftw implementation that will
1227: not follow symlinks.
1228:
1229: 0.5.7:
1230: oops, if_nametoindex was broken!
1231:
1232: 0.5.6:
1233: ported to ppc-linux.
1234: fixed i386 sigsetjmp (I mistyped the function name)
1235: included sigjmp.c
1236:
1237: 0.5.5:
1238: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1239: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1240: I fixed it now.
1241: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1242: fixed readdir to use getdents and not the intel inline asm
1243:
1244: 0.5.4:
1245: ported to sparclinux (sparc32 only). Beware: does not work yet.
1246: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1247:
1248: 0.5.3:
1249: added tcsetattr and getenv to compile e3
1250:
1251: 0.5.2:
1252: added vhangup, tcgetattr, isatty and memcmp for fgetty
1253: (http://www.fefe.de/fgetty/)
1254: added localtime from uC-libc.
1255:
1256: 0.5.1:
1257: stat and friends actually work now. Yuck! Another case of
1258: translation between kernel and userland. Why can't the kernel
1259: people and the libc people simply agree on a standard?
1260: removed many unnecessary includes to speed up compilation.
1261: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1262: inlined socketcall to reduce code size.
1263: "load" and "compile" are examples for djb code.
1264:
1265: 0.5:
1266: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1267: each object file is now treated with "strip -x -R .note -R .comment"
1268: split each system call into a separate object file
1269: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1270:
1271: 0.4.1:
1272: oops, the strchr implementation was wrong. Thanks Jens Laas!
1273:
1274: 0.4:
1275: copied opendir and friends from uC-libc.
1276: added getservent and getservby* in gerservent.c
1277:
1278: 0.3:
1279: remove readdir system call
1280: added getdents system call
1281: added getpwnam/getpwuid implementation in getpwnam.c
1282: added a few string functions (in str*.c)
1283:
