370: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 371: add libm2.s from contrib to i386 (oops, how long has it been sitting
372: there?)
1.284 fefe 373: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 374: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 375: upcoming AMD Hammer chips!). You can't even buy the chips yet and
376: the diet libc already supports it! Amazing ;-)
377: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 378: Andre sent a patch to add ARM profiling. He says it does not work
379: yet, but it's a start.
1.287 fefe 380: added getdents64 backwards compatibility and include it in large file
381: support #defines
1.288 fefe 382: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

414: adjusted lstat->lstat64 #define to make it work with function pointers
415: move __dietlibc__ #define from features.h to diet
1.267 fefe 416: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
417: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 418: Thomas also sent me profiling support (so far only on x86, but
419: profiling/PORTING describes what needs to be done for other
420: architectures)!
1.272 fefe 421: add contrib/dprof.c, also from Thomas.
1.269 fefe 422: Andreas Krennmair sent a patch to add the BSD regex interface to
423: libcompat
1.271 fefe 424: Andre noticed that __dtostr never sets first to false. Oops!

1.275 fefe 426: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 427: abort did not flush all stdio streams
1.277 fefe 428: fix some nasty regular expression bugs
429: write a stupid malloc checker (contrib/debug-realloc.c) to help me
430: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 431: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 432: fix DNS domain search
1.280 fefe 433: i386 memccpy exchanged esi and edi :-( I should do more checks before
434: accepting external code...
1.264 fefe 435:
1.244 fefe 436: 0.16:
437: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 438: Andre found two very embarassing bugs in my four lines of md5 glue.
439: I need to get more sleep.
1.247 fefe 440: Thanks Ogrisegg found that ptrace does not work as documented and
441: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 442: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
443: fix ptrace.h for S/390 and ARM
444: provide a PORTING document so we don't lose track of which file need
445: to be touched to port the diet libc to a new platform.
1.249 fefe 446: remove a few warnings
447: provide a prototype for usleep.
1.250 fefe 448: make __dtostr work on ARM by using long instead of long long.
449: Idea by Dirk Engling.
1.251 fefe 450: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 451: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 452: Kurt Garloff sent in patches to
453: fix struct termios on non-x86 architectures
1.254 fefe 454: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
455: create libcompat.a (and move daemon to it)
1.255 fefe 456: add getdelim and getline
457: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 458: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 459: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 460: Hans Lermen fixed i386/getenv.S
1.259 fefe 461: diet -Os no longer discards -fpic and -fno-pic

1.244 fefe 467:
1.224 fefe 468: 0.15:
1.225 fefe 469: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 470: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 471: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
472: thread-safe!
1.228 fefe 473: remove vfork and add alarm to dynamic syscalls.
474: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 475: The MD5 code generated unaligned accesses when passed an unaligned
476: pointer on little endian ARM and MIPS.
477: MIPS unified syscall didn't compile anymore.
478: Put up new mipsel target to cross compile for little endian mips.
479: The mips target will again explicitly set endianness to big endian.
480: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 481: Duh, when we removed return0, we broke tzset when the time zone parser
482: was disabled. Uwe Ohse noticed this. Thanks!
483: Fix gethostbyname to match host names case insensitively in /etc/hosts.
484: Oops, this was reported 6 weeks ago but I overlooked the email.
485: Thanks, Denis Rachal!
1.231 fefe 486: vsnprintf's zero termination was broken.
1.233 fefe 487: Uwe Ohse found a few more bugs:
488: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
489: does it correctly.
490: Make inet_aton use strtoul instead of strtol
491: fdopen would close the file descriptor if it could not malloc the
492: buffer.
493: strftime updates.
494: Make _FILE_OFFSET_BITS includes -Wundef clean
495: Andre found a typo in endian.h for big endian mips
1.234 fefe 496: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 497: strstr(whatever,"") returned NULL, not whatever. Found by a new test
498: suite entry for strstr that I wrote.
1.245 fefe 499: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 500: add <asm/sigcontext.h> for profiling support.
501: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 502: an i386 assembler getenv implementation (roughly half the size)
503: add grantpt, ptsname, unlockpt
1.236 fefe 504: add a getenv test suite entry.
1.238 fefe 505: Andre contributed an ARM assembler md5 implementation and he fixed mmap
506: on ARM.
507: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 508: getservent_r did not parse lines without aliases. Thanks, Jaroslav
509: Macodiseas!
1.240 fefe 510: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 511: removed annoying -Wconversion gcc switch
1.242 fefe 512: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 513: Kurt Garloff sent these diffs:
514: add fdatasync (and make it a pthread cancellation point)
515: numerous alpha issues, like using .quad instead of .long for
516: offsets, change strip to -strip in Makefile (so a failing strip does
517: not abort the make), try to be more friendly to the gcc 2.96 that
518: SuSE 7.1 AXP ships with.
1.224 fefe 519:
1.209 fefe 520: 0.14:
1.224 fefe 521: fix brk again (missing __brk, trivial oversight)
1.210 fefe 522: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
523: Thomas Ogrisegg!
1.211 fefe 524: Thomas also contributed a PA-RISC port including testandset, so
525: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 526: made the fake locale more believable.
527: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 528: moved _exit into the unified syscall on x86.
1.214 fefe 529: Uwe Ohse found many more bugs:
530: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
531: liblatin1 was more or less completely broken if you gave it chars as
532: arguments, not ints (signedness). execvp had a buffer overflow in
533: case a PATH element exceeded PATH_MAX, but it's not a security
534: problem since setuid programs need to set their path to some known
535: value anyway.
1.219 fefe 536: hasmntopt did not work with foo=bar style options
1.217 fefe 537: Uwe also improved ftw's stack usage.
1.214 fefe 538: Put movl instead of popl rationale in comment in i386/unified.S since
539: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 540: I discovered __attribute__((malloc)) and started using it. For gcc 3,
541: it improves the optimizer when functions return malloced pointers.
1.216 fefe 542: Steven Rostedt pointed out that my setvbuf was broken with regard to
543: size==0 and sent a patch to fix it.
1.218 fefe 544: Thomas Ogrisegg made setenv smaller.
1.220 olaf 545: Olaf: implemented the parisc clone and an atomic testandset, modified the
546: libpthread to respect the parisc UPgrowing stack. still non functional,
547: because the unified syscall uses errno :(
1.221 fefe 548: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 549: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
550: don't write anything which was no longer the case. It also
551: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 552: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 553:
1.193 fefe 554: 0.13:
1.194 fefe 555: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 556: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 557: Olaf: port to S/390!
1.463 leitner 558: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 559: res_query did not initialize last
1.199 fefe 560: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 561: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 562: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 563: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 564: rewrote __dtostr (it also has one more argument now)
1.205 fefe 565: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 566: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
567: fix strncat for the case where n == 0 (security implications?)
568: fix bsearch (it didn't find the very last element in the array, same
569: bug in both the C and the i386 assembly version).
1.205 fefe 570: fixed FNM_PATHNAME in fnmatch
1.204 fefe 571: fix brk (the syscall was documented incorrectly in the Linux man page)
572: Thanks, Thomas Ogrisegg!
1.205 fefe 573: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 574: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 575: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 576:
1.164 fefe 577: 0.12:
578: more contributions from Frank Klemm.
1.165 fefe 579: iconv can now do UCS-2, too.
1.167 fefe 580: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 581: Lots of bug fixes, and several more i386 specific versions of common
582: routines to make them smaller.
1.168 fefe 583: add memmem (a GNU extension that looks useful)
1.170 fefe 584: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 585: add pivot_root syscall, %n for *scanf.
1.169 fefe 586: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 587: add Frank Klemm's optimized md5
1.172 fefe 588: add -Os option to diet (see diet.1).
1.173 fefe 589: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 590: add 32-bit uid/gid syscalls.
1.175 fefe 591: add rand48 (thanks, Johannes Kloos)
1.176 fefe 592: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 593: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
594: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
595: fix gethostent alias list termination. Major oops.
1.178 fefe 596: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 597: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 598: DNS will now properly signal errors and set h_errno.
599: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 600: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
601: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
602: external reference to a symbol that is only in the diet libc. So,
603: when you accidentally link a diet libc compiled object file against
604: glibc, the linker will barf. This will bloat your object files, but
605: you can remove all the references with "strip -R .note" from
606: the binaries in the end (which you should do anyway).
1.182 fefe 607: fix ARM unified syscall (select did not work).
1.183 fefe 608: add getpwent_r ala glibc and replace getpwent
609: do the same for getgrent and getspent
610: remove entlib (new code is smaller)
1.184 fefe 611: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 612: add getpwnam_r and getpwuid_r
1.186 fefe 613: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 614: Olaf muddled with the dynamic linker. It's a clean-room
615: implementation in the sense that it once worked for Olaf in a clean
616: room ;)
1.188 fefe 617: add if_nameindex and if_freenameindex.
618: fixed arm unified syscalls to work with current binutils (; is no
619: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 620: changed all st_[cma]time types to signed long so comparisons against
621: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 622: fixed two bugs regarding ungetc.
623: add getusershell, setusershell, endusershell (for vs_ftpd)
624: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 625: fixed strftime (was completely hosed)
1.192 fefe 626: added real make install target
1.164 fefe 627:
1.115 fefe 628: 0.11:
629: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 630: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 631: add floor, ceil and memchr prototypes.
632: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 633: cleaner errno vs __errno_location handling
634: add placeholder iconv (iconv_open will always return EINVAL)
635: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
636: initialization of getaddrinfo.
1.119 fefe 637: fix vsnprintf %X (printed lower case)
1.120 fefe 638: I wrote a new getopt. It appears to actually work (it is POSIX
639: compliant, it does not sort argv like the GNU version) and is only
640: a little over 300 bytes on x86.
1.121 fefe 641: Guillaume Cottenceau just wrote me that strncat should be even more
642: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 643: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 644: Fix regexec offset return. autoconf now believes that diet libc has
645: POSIX regular expressions.
1.123 fefe 646: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 647: Fix regular expression match for x* when there is no x at all.
1.125 fefe 648: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 649: Add %h to vsnprintf.
1.127 fefe 650: Add FAQ.
1.128 fefe 651: Make %h work for signed numbers and add %hh to vsnprintf.
652: initgroups ignored the group argument :-(
653: remove printf references and nested functions from glob.
1.129 fefe 654: added an errno in libpthread that will display a prominent linker
655: warning.
1.131 fefe 656: started getting rid of kernel headers. Big task! :-(
1.130 fefe 657: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 658: Olaf: added a lot of code in libdl (not yet complete), changed the
659: startup code to make it work with his libdl and ld.so (needs still work
660: too)
1.134 fefe 661: __dns_readstartfiles only took the first domain or search path.
662: Thanks, Anthony de Boer
1.133 olaf 663: Olaf: added clone and a new unified_syscall for PowerPC
664: also dynlinker is now available (i386 only at this time)
1.135 fefe 665: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 666: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 667: fixed word delimiters in regex (they looked for space, i.e. "," did
668: not work as delimiter)
1.138 fefe 669: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 670: added mkdtemp.
1.142 fefe 671: Uwe Ohse reported all of the following bugs:
672: ttyname should return 0 if !isatty.
673: realpath returns NULL if "." cannot be opened
674: putenv erroneously accepted (and mishandled) entries without "=".
675: popen returned 255 instead of 127 if /bin/sh could not be run.
676: fgetc did not set the internal EOF indicator on EOF.
677: bsearch contained an assumption about integer arithmetic overflow
678: behavior.
679: system did not set SIGCHLD and thus contained a race.
680: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 681: daemon did not check whether open returns an fd below 3
682: perror did not save errno.
1.144 olaf 683: Olaf: Peter Jones reported some problems with perror; strerror had the
684: same problem.
685: Peter also posted a patch to atexit/exit. With some modifications it is
686: now implemented.
1.145 fefe 687: Unbuffered stdio and ungetc can no longer be disabled. I will try to
688: implement part of it using ELF weak symbols.
1.146 fefe 689: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 690: Added overflow handling for strtoul and strtol.
1.149 fefe 691: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
692: it before falling back to DNS if enabled.
1.150 fefe 693: Added a littie backwards compatibility cruft for gpm (man, do these
694: sources stink!)
1.151 fefe 695: Added openpty.
1.152 fefe 696: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 697: Fix fseek return value.
1.155 fefe 698: Add dirname and basename.
1.156 fefe 699: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 700: Fixed getservent (did not allow _ and - in the aliases).
701: Thanks, Oden Eriksson
1.158 fefe 702: Added a float.h so configure believes we have ANSI header files.
703: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 704: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 705: scanf and printf function implementations
1.160 fefe 706: Imported a few more functions and optimizations from Frank Klemm (he
707: also rewrote dtostr to have more precision)
1.161 olaf 708: Olaf: checked in a new sig* function family (based on rt_sig*).
709: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 710: Made rudimentary iconv that can convert back and forth between
711: iso-8859-1, utf-8 and ucs-4 (for debugging).
712: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 713:
1.74 fefe 714: 0.10:
715: update getpagesize.
716: add personality.
1.75 fefe 717: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 718: add putchar (apparently arm-linux-gcc will substitute printf("\n")
719: with putchar('\n') behind your back...?!
1.77 fefe 720: import include/scsi/ from glibc.
1.78 fefe 721: add iopl.
1.80 fefe 722: add execl and sigdelset prototypes.
723: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 724: add RPC headers (no code yet).
1.82 fefe 725: add mlockall, munlockall
1.83 fefe 726: make "diet gcc foo.c" work.
727: added Sun RPC code and removed as many warnings as possible in a
728: heroic act of self-mutilation.
729: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 730: added getpass. mount from util-linux actually compiles now!
731: fix the sig*set routines. mount actually works now *bg*
732: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 733: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 734: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 735: add res_init.
736: add asprintf (ugh, what an ugly function).
1.89 fefe 737: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 738: add ut_name alias to ut_host in struct utmp.
739: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 740: add sysinfo, recvmsg, sendmsg.
1.93 fefe 741: add endmntent, getmntent, setmntent.
1.94 fefe 742: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 743: add setenv.
744: remove __restrict from mntent.h, add __restrict__ removal alias for
745: older gcc versions in sys/cdefs.h.
746: add rlim_t, sig_atomic_t declarations.
747: add sigsetjmp #define for __sigsetjmp (oops).
748: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 749: add a gruesome hack to printf floating point to accept %f and kludge
750: together support for %.2f. Don't look at the code, please!
1.98 fefe 751: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 752: imported fix for entlib by Jeff Garzik.
1.100 fefe 753: add glob implementation from Guillaume Cottenceau (Thanks!!)
754: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 755: add REG_ICASE and word start/end handling to my regular expressions.
756: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 757: wrap getcwd to comply to man page (the syscall returns the number of
758: bytes, not the buffer)
759: add realpath.
1.103 fefe 760: fix vfprintf.
1.104 fefe 761: fix *scanf %s zero termination.
762: add abs, labs, llabs.
1.105 fefe 763: add <sys/io.h>, ioperm syscall.
764: add flock to <sys/file.h>
1.106 fefe 765: fixes to bsearch and the regular expressions.
1.107 fefe 766: add fake herror.
1.108 fefe 767: add scandir and alphasort.
1.109 fefe 768: add killpg
1.110 fefe 769: implemented a gross hack to make libpthread compile when
770: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 771: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 772: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 773: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
774: for sending a patch.
1.114 fefe 775: add getserv*.
776: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
777: "search" from resolv.conf.
1.74 fefe 778:
1.73 fefe 779: 0.9:
1.65 fefe 780: fixed initgroups (oops)
1.66 fefe 781: Cleanup appending file open for stdio (thanks, James Antill)
782: imported vfprintf fix from James Antill.
1.67 fefe 783: add fnmatch
784: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 785: Olaf added character classes to *scanf.
1.69 fefe 786: Put object and library files into a separate directory (bin-$ARCH).
787: Add "cross" make target to make all architectures.
788: Add "diet" program and man page.
1.70 fefe 789: Add getgrnam, getgrgid
1.71 fefe 790: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 791: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 792:
1.64 fefe 793: 0.8:
1.34 fefe 794: vsnprintf(0,...) estimated the length of strings with a padding width
795: incorrectly.
1.35 fefe 796: new reboot() from Olaf.
1.36 fefe 797: added prototypes for getsockopt and setsockopt.
1.39 fefe 798: added experimental sem* and shm*
1.38 fefe 799: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 800: added setvbuf (only changes mode, not buffer)
1.41 fefe 801: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
802: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 803: added qsort() and bsearch(). Benchmark on 1000 random ints:
804: glibc: 679414 cycles qsort and 3352 cycles bsearch
805: diet libc: 300010 cycles qsort, 553 cycles bsearch
806: I have no idea why glibc is so slow.
1.43 fefe 807: added __isnan (references by libm.a from glibc).
808: added popen() and pclose(). Now the diet libc can link slsh (from
809: S-Lang!)
1.44 fefe 810: corrected usleep. It was more of an msleep until now.
1.45 fefe 811: corrected __dtostr (it looped when trying to format "0.0").
812: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 813: added ungetc (does it work?)
1.47 fefe 814: added inet_aton (yuck!)
1.50 fefe 815: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 816: added h_errno and __h_errno_location
817: added inet_ntoa
1.49 fefe 818: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 819: add bcopy, index, rindex macros
820: add isgraph and isxdigit
1.52 fefe 821: add strftime (ugh!!!)
1.53 olaf 822: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 823: Jeff Garzik contributed a spec file. I put it in contrib and hope
824: everbody knows what to do with it...
825: Olaf checked in a ton of libpthread stuff.
1.55 fefe 826: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 827: add large file backwards compatibility support (so gzip will run on
828: kernel 2.2 and 2.0)
1.57 fefe 829: added shutdown
1.58 fefe 830: added nice
831: added pseudo-locale support for is* (they are now weak aliases,
832: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
833: overwrite the default is* functions.
1.59 fefe 834: added liblatin1.a
1.60 fefe 835: added tzfile implementation (does it work for anyone else?)
1.61 fefe 836: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 837: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
838: Thanks!
1.63 fefe 839: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 840:
1.21 fefe 841: 0.7.2:
842: added several prototypes to already implemented functions and
843: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 844: added prototypes for process group and dup syscalls. Thanks to
845: Abraham again. He also contributed an implementation for daemon(),
846: an ugly BSD hack. I decided to diversify the lib/ directory a
847: little and now created a libugly/ directory for stuff like system()
848: and daemon() ;-)
849: added libstdio and moved all that stdio crap from lib/ there. The
850: idea is to start separating now what we will separate for shared
851: libraries anyway.
1.26 fefe 852: optimized x86 unified-syscall by Olaf.
1.27 fefe 853: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
854: limits.h instead)
855: added remove.c and enough cruft to limits.h to make it compile lzo,
856: lzop and bzip2.
1.28 fefe 857: added mktime, asctime_r, asctime and ctime (needed for gzip).
858: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 859: format some day (man tzfile, ugh!) :-(
1.29 fefe 860: added unlink prototype to unistd.h.
861: added gmtime and gmtime_r.
1.31 fefe 862: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 863: removed readdir glibc compatibility cruft.
1.31 fefe 864: removed stat glibc compatibility cruft.
1.32 fefe 865: oops, my fread was broken for pipes.
1.33 fefe 866: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 867:
1.9 fefe 868: 0.7.1:
1.11 fefe 869: optimized away the static arrays from __ltostr and __lltostr.
870: optimized away the static arrays (and more!) from strtoul and strtoull.
871: added system (by Olaf).
1.12 fefe 872: added tolower and toupper
1.13 fefe 873: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 874: added clone for mips (by Olaf).
875: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 876: added pause for all (by Olaf).
1.17 fefe 877: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 878: added isupper and islower.
879: added putc and putchar as macros.
1.17 fefe 880: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
881: insightful discussions and patches I partially used for the last three)
1.18 fefe 882: added getpriority and setpriority (also by Abraham)
1.19 fefe 883: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 884: oi, setjmp and longjmp were broken on other platforms, too!
885: Thanks to Sébastien Côté for reporting this.
1.9 fefe 886:
887: 0.7:
1.6 olaf 888: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 889: Initial dynamic loading glue for i386, also by Olaf.
890: We don't have a dynamic loader yet, so this is not yet usable.
891: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
892: vsprintf, writev, all by Olaf.
1.2 fefe 893: imported readdir fix from Guillaume. Mhh, can the kernel interface
894: really be this broken?
1.3 fefe 895: Found a kludgy way to detect whether the kernel includes define struct
896: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
897: not work for you, please tell me!
1.4 fefe 898: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 899: Fixed stdio line buffering. The code was already there but I forgot
900: to mark stdio and stdout as line buffered. This should really be
901: done dynamically using isatty, though.
1.8 fefe 902: Removed superfluous "if (1)" in execvp.c
1.1 cvs 903:
904: 0.6.14:
905: *scanf did not append the 0 byte for %s.
906: added creat and changed creat to call open directly instead of open64.
907: did for fread what 0.6.10 did for fwrite.
908: repaired buffered stdio a little (line buffering is still not
909: supported).
910: [All of these bugs have been reported by Guillaume. Thanks!]
911: added __pure__ to strchr and strrchr in <string.h>
912:
913: 0.6.13:
914: included COPYING to make clear that the diet libc is covered by the
915: GNU General Public License (and _not_ the LGPL). That means that
916: you need to obtain a license from me if you want to use the diet
917: libc in a proprietary program that you want to distribute.
918: The x86 unified syscall swapped arguments #4 and #5 and noone
919: noticed until now! Thanks to Guillaume Cottenceau for reporting
920: this!
921: The malloc had a subtle bug with small allocations that could cause
922: segfault. Guillaume reported it, Olaf fixed it.
923:
924: 0.6.12:
925: added assert, statfs and fstatfs
926: added include/net/if.h so fget compiles again.
927:
928: 0.6.11:
929: added putenv.
930:
931: 0.6.10:
932: fixed fwrite. It returned the number of bytes written, not the number
933: of records. Thanks to Albert D. Cahalan for pointing this out.
934: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
935: added brk and sbrk. harold@nb.com.sg made me do it.
936:
937: 0.6.9:
938: fixed execvp not to return on ENOENT
939: did for {open|read|close|seek|tell}dir what I did for stat before.
940: The glibc compatibility part is currently non-functional.
941: fixed white space handling in sscanf " (" would not match " (".
942: fixed printf to accept 'l' flag.
943: fixed getpwuid (ignored last line)
944:
945: 0.6.8:
946: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
947: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
948: added strlcpy and strlcat from OpenBSD.
949: added stat64, fstat64 and lstat64.
950: added endian.h and made ending of strlen.c endianness-aware
951: added string routines size tweak to dietfeatures.h. Most of the
952: string routines have been unrolled. This is up to three times as
953: fast but creates up to three times larger code. Now you can disable
954: the unrolling.
955: added sendfile.
956: I also added pread. It works on x86 and sparc but not on ppc and mips.
957: I have no idea what's going on. strace disagrees with the kernel.
958: Can anyone help? I asked the Linux kernel mailing list for help, too.
959: added a few aliases of the type __libc_open for open. nm on
960: libpthreads.so indicates that we will need them.
961:
962: 0.6.7:
963: the sources now compile without warnings with -Wall.
964: printf now prints "(null)" when %s is passed NULL. This can be
965: removed with WANT_NULL_PRINTF in dietfeatures.h
966: added vfprintf, execl, ttyname.
967: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
968: __dietfstat so they can use the normal kernel struct stat.
969: stat, lstat and fstat are now C wrappers that convert to the glibc
970: struct stat. So we can avoid that overhead for programs that use
971: dietlibc headers.
972:
973: 0.6.6:
974: changed the Makefiles so you can now set CFLAGS on the command line
975: added memccmp (analogous to memccpy) and strncmp.
976: Olaf fixed another bug in the sparc unified syscall.
977: Paul Clifford contributed a C version of his strlen.S that is much
978: more efficient than the previous strlen on all platforms! It also
979: looks like technology from Roswell. ;-}
980: added a "real" stdio. Well, almost. Please contribute!
981: added dietfeatures.h so you can remove features you don't need.
982: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
983: stdio now works with simple programs and minigzip from libz.
984: stdio uses some major trickery to avoid linking the stdio, stderr and
985: stdout (and reserving space for them) when they are not used.
986:
987: 0.6.5:
988: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
989: most of them bugs in the new header files, but also missing sigset
990: functions.
991: Paul Clifford contributed an assembly strlen.S for ARM and fixed
992: several bugs.
993: Fixed ppc/setjmp and mips/pipe.
994: Olaf contributed a new sparc unified syscall.
995:
996: 0.6.4:
997: declared is* static inline in getservent.
998: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
999: changed strlen to return 0 when passed NULL.
1000: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
1001: Scientist who actually implemented this without access to a MIPS
1002: box, just from reading the architecture manual. And it worked out
1003: of the box.
1004: started a set of system includes, mainly so that I can use lcc and
1005: my alpha-linux cross compiler (which is unable to cross-compile
1006: glibc). diet libc can now be compiled without any include files
1007: from a normal libc. The includes do declare more than diet libc
1008: currently delivers and they are still far from complete for real
1009: applications.
1010: I will only add assembly versions that are smaller _and_ faster than
1011: the C version. Larger routines are only accepted if they are called
1012: very often and are substantially faster.
1013: added i386 assembly strchr, which is smaller and faster than the old
1014: version. It is, however, larger than the version contributed by
1015: proton (thanks, anyway).
1016: added i386 strlen (31% faster, 14% smaller)
1017: "make t" will now create a map file called "mapfile".
1018:
1019: 0.6.3:
1020: added sys_errlist, strerror and perror
1021: added isblank
1022: added atol
1023:
1024: 0.6.2:
1025: mmap for ARM didn't compile. Thanks, Paul!
1026:
1027: 0.6.1:
1028: split mmap into the architecture specific subdirectories.
1029: getenv now copes with environ==NULL, thanks Paul Clifford.
1030: Paul also contributed a smaller ARM startup code.
1031:
1032: 0.6:
1033: strcat returned the wrong result. Thanks, Dietz Pröpper.
1034: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1035: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1036: __dtostr does not work (I have no idea why!)
1037: The MIPS port now uses (much smaller) non-PIC code. That means that
1038: the applications you link against diet libc also have to be compiled
1039: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1040: Thanks to Ralf Bächle for helping me with this!
1041: I made subdirectories for the architectures and use VPATH to override
1042: VPATH so that make finds the source file automatically. That should
1043: simplify the sources greatly.
1044: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1045: ARM and MIPS now also have setjmp and longjmp
1046: "compile" and "load" are now make targets. Use them for djb programs.
1047: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1048: Again, contributed from Olaf. Great work!
1049:
1050: 0.5.12:
1051: printf also does signed numbers.
1052: If you don't use atexit, dietlibc now does not link exit, only _exit.
1053: *printf now correctly returns the number of bytes written.
1054: Olaf contributed experimental sscanf and vsscanf implementations.
1055: If passed NULL as buffer, snprintf will not write anything but still
1056: return the number of bytes it would have written.
1057: Initial MIPS port! (Oh, the agony!)
1058: No setjmp and longjmp support yet! Please contribute!
1059: I even implemented unified syscalls for MIPS. Still, MIPS code is
1060: almost twice the size of SPARC code. If anyone knows why: please
1061: tell me!
1062:
1063: 0.5.11:
1064: I implemented new unified syscalls for x86, sparc and ppc, this time based
1065: on .s files and not .c files, and I moved the syscalls into
1066: subdirectores to clean the dietlibc sources up a little.
1067: A binary consisting of printf("%s is %d\n","olaf",23) is now
1068: 2864 bytes on sparc
1069: 2488 bytes on intel
1070: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1071: to make a few more applications work.
1072: Olaf Dreesen also implemented some unified syscall stuff for x86.
1073: He discovered that with our unified syscall interface it actually
1074: costs <10 bytes total to make all system calls thread safe!
1075: I implemented atexit() (can register up to 4 callbacks).
1076: I implemented strtod and __dtostr (the opposite). Now we can add
1077: floating point support to vsnprintf and sscanf!
1078:
1079: 0.5.10:
1080: I actually saw that I can not only merge the errno handling code of
1081: the system calls on x86, I can also merge the rest (including the
1082: arguments) except for setting the system call number. All those
1083: system calls are now just a jump to a unified system call handler.
1084: I got rid of x86openclose again. The savings are substantial:
1085: chown from embutils went from 7664 to 7184 bytes!
1086: If I'd move the system call wrappers to assembly language, I could
1087: even reduce the alignment (does not matter since it's just a jump
1088: anyway) and get rid of the "ret" behind each jump (one byte per
1089: system call!)
1090:
1091: 0.5.9:
1092: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1093: fixed strdup
1094: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1095: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1096: (no signed integers, only strings and unsigned integers (but
1097: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1098: that code must be wonderful, I don't understand it at all *bg*)
1099: Olaf's printf does understand padding like in "%08d" and "%8d" and
1100: automatically pads pointers with '0'.
1101: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1102: Thanks to proton for inspiration on this.
1103: The new x86 start code also does not reference exit any more, thus saving
1104: 64 bytes for executables that don't call exit explicitly.
1105: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1106: Moved errno and environ to start.S, saving no byte binary size but
1107: speeding up compilation and slightly shortening dietlibc.a ;-)
1108: For x86: joined open and close into one assembler file, sharing the
1109: errno handling. This is a feasibility test and it actually saves a
1110: few bytes. I think I will reimplement the _syscall[1-6] macros on
1111: all platforms now to share the errno handling code for them.
1112:
1113: 0.5.8:
1114: fixed strchr to be able to look for 0.
1115:
1116: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1117: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1118: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1119: contributed by Olaf Dreesen)
1120:
1121: added execvp, getcwd
1122:
1123: fixed __xmknod
1124:
1125: Note: can it be that the ftw interface really is so broken that I
1126: cannot implement it without having to implement some searching data
1127: structure? I included an experimental ftw implementation that will
1128: not follow symlinks.
1129:
1130: 0.5.7:
1131: oops, if_nametoindex was broken!
1132:
1133: 0.5.6:
1134: ported to ppc-linux.
1135: fixed i386 sigsetjmp (I mistyped the function name)
1136: included sigjmp.c
1137:
1138: 0.5.5:
1139: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1140: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1141: I fixed it now.
1142: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1143: fixed readdir to use getdents and not the intel inline asm
1144:
1145: 0.5.4:
1146: ported to sparclinux (sparc32 only). Beware: does not work yet.
1147: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1148:
1149: 0.5.3:
1150: added tcsetattr and getenv to compile e3
1151:
1152: 0.5.2:
1153: added vhangup, tcgetattr, isatty and memcmp for fgetty
1154: (http://www.fefe.de/fgetty/)
1155: added localtime from uC-libc.
1156:
1157: 0.5.1:
1158: stat and friends actually work now. Yuck! Another case of
1159: translation between kernel and userland. Why can't the kernel
1160: people and the libc people simply agree on a standard?
1161: removed many unnecessary includes to speed up compilation.
1162: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1163: inlined socketcall to reduce code size.
1164: "load" and "compile" are examples for djb code.
1165:
1166: 0.5:
1167: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1168: each object file is now treated with "strip -x -R .note -R .comment"
1169: split each system call into a separate object file
1170: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1171:
1172: 0.4.1:
1173: oops, the strchr implementation was wrong. Thanks Jens Laas!
1174:
1175: 0.4:
1176: copied opendir and friends from uC-libc.
1177: added getservent and getservby* in gerservent.c
1178:
1179: 0.3:
1180: remove readdir system call
1181: added getdents system call
1182: added getpwnam/getpwuid implementation in getpwnam.c
1183: added a few string functions (in str*.c)
1184:
