361: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 362: add libm2.s from contrib to i386 (oops, how long has it been sitting
363: there?)
1.284 fefe 364: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 365: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 366: upcoming AMD Hammer chips!). You can't even buy the chips yet and
367: the diet libc already supports it! Amazing ;-)
368: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 369: Andre sent a patch to add ARM profiling. He says it does not work
370: yet, but it's a start.
1.287 fefe 371: added getdents64 backwards compatibility and include it in large file
372: support #defines
1.288 fefe 373: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

405: adjusted lstat->lstat64 #define to make it work with function pointers
406: move __dietlibc__ #define from features.h to diet
1.267 fefe 407: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
408: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 409: Thomas also sent me profiling support (so far only on x86, but
410: profiling/PORTING describes what needs to be done for other
411: architectures)!
1.272 fefe 412: add contrib/dprof.c, also from Thomas.
1.269 fefe 413: Andreas Krennmair sent a patch to add the BSD regex interface to
414: libcompat
1.271 fefe 415: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 416: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 417: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 418: abort did not flush all stdio streams
1.277 fefe 419: fix some nasty regular expression bugs
420: write a stupid malloc checker (contrib/debug-realloc.c) to help me
421: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 422: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 423: fix DNS domain search
1.280 fefe 424: i386 memccpy exchanged esi and edi :-( I should do more checks before
425: accepting external code...
1.264 fefe 426:
1.244 fefe 427: 0.16:
428: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 429: Andre found two very embarassing bugs in my four lines of md5 glue.
430: I need to get more sleep.
1.247 fefe 431: Thanks Ogrisegg found that ptrace does not work as documented and
432: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 433: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
434: fix ptrace.h for S/390 and ARM
435: provide a PORTING document so we don't lose track of which file need
436: to be touched to port the diet libc to a new platform.
1.249 fefe 437: remove a few warnings
438: provide a prototype for usleep.
1.250 fefe 439: make __dtostr work on ARM by using long instead of long long.
440: Idea by Dirk Engling.
1.251 fefe 441: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 442: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 443: Kurt Garloff sent in patches to
444: fix struct termios on non-x86 architectures
1.254 fefe 445: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
446: create libcompat.a (and move daemon to it)
1.255 fefe 447: add getdelim and getline
448: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 449: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 450: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 451: Hans Lermen fixed i386/getenv.S
1.259 fefe 452: diet -Os no longer discards -fpic and -fno-pic

1.244 fefe 458:
1.224 fefe 459: 0.15:
1.225 fefe 460: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 461: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 462: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
463: thread-safe!
1.228 fefe 464: remove vfork and add alarm to dynamic syscalls.
465: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 466: The MD5 code generated unaligned accesses when passed an unaligned
467: pointer on little endian ARM and MIPS.
468: MIPS unified syscall didn't compile anymore.
469: Put up new mipsel target to cross compile for little endian mips.
470: The mips target will again explicitly set endianness to big endian.
471: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 472: Duh, when we removed return0, we broke tzset when the time zone parser
473: was disabled. Uwe Ohse noticed this. Thanks!
474: Fix gethostbyname to match host names case insensitively in /etc/hosts.
475: Oops, this was reported 6 weeks ago but I overlooked the email.
476: Thanks, Denis Rachal!
1.231 fefe 477: vsnprintf's zero termination was broken.
1.233 fefe 478: Uwe Ohse found a few more bugs:
479: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
480: does it correctly.
481: Make inet_aton use strtoul instead of strtol
482: fdopen would close the file descriptor if it could not malloc the
483: buffer.
484: strftime updates.
485: Make _FILE_OFFSET_BITS includes -Wundef clean
486: Andre found a typo in endian.h for big endian mips
1.234 fefe 487: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 488: strstr(whatever,"") returned NULL, not whatever. Found by a new test
489: suite entry for strstr that I wrote.
1.245 fefe 490: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 491: add <asm/sigcontext.h> for profiling support.
492: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 493: an i386 assembler getenv implementation (roughly half the size)
494: add grantpt, ptsname, unlockpt
1.236 fefe 495: add a getenv test suite entry.
1.238 fefe 496: Andre contributed an ARM assembler md5 implementation and he fixed mmap
497: on ARM.
498: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 499: getservent_r did not parse lines without aliases. Thanks, Jaroslav
500: Macodiseas!
1.240 fefe 501: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 502: removed annoying -Wconversion gcc switch
1.242 fefe 503: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 504: Kurt Garloff sent these diffs:
505: add fdatasync (and make it a pthread cancellation point)
506: numerous alpha issues, like using .quad instead of .long for
507: offsets, change strip to -strip in Makefile (so a failing strip does
508: not abort the make), try to be more friendly to the gcc 2.96 that
509: SuSE 7.1 AXP ships with.
1.224 fefe 510:
1.209 fefe 511: 0.14:
1.224 fefe 512: fix brk again (missing __brk, trivial oversight)
1.210 fefe 513: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
514: Thomas Ogrisegg!
1.211 fefe 515: Thomas also contributed a PA-RISC port including testandset, so
516: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 517: made the fake locale more believable.
518: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 519: moved _exit into the unified syscall on x86.
1.214 fefe 520: Uwe Ohse found many more bugs:
521: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
522: liblatin1 was more or less completely broken if you gave it chars as
523: arguments, not ints (signedness). execvp had a buffer overflow in
524: case a PATH element exceeded PATH_MAX, but it's not a security
525: problem since setuid programs need to set their path to some known
526: value anyway.
1.219 fefe 527: hasmntopt did not work with foo=bar style options
1.217 fefe 528: Uwe also improved ftw's stack usage.
1.214 fefe 529: Put movl instead of popl rationale in comment in i386/unified.S since
530: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 531: I discovered __attribute__((malloc)) and started using it. For gcc 3,
532: it improves the optimizer when functions return malloced pointers.
1.216 fefe 533: Steven Rostedt pointed out that my setvbuf was broken with regard to
534: size==0 and sent a patch to fix it.
1.218 fefe 535: Thomas Ogrisegg made setenv smaller.
1.220 olaf 536: Olaf: implemented the parisc clone and an atomic testandset, modified the
537: libpthread to respect the parisc UPgrowing stack. still non functional,
538: because the unified syscall uses errno :(
1.221 fefe 539: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 540: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
541: don't write anything which was no longer the case. It also
542: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 543: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 544:
1.193 fefe 545: 0.13:
1.194 fefe 546: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 547: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 548: Olaf: port to S/390!
1.463 leitner 549: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 550: res_query did not initialize last
1.199 fefe 551: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 552: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 553: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 554: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 555: rewrote __dtostr (it also has one more argument now)
1.205 fefe 556: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 557: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
558: fix strncat for the case where n == 0 (security implications?)
559: fix bsearch (it didn't find the very last element in the array, same
560: bug in both the C and the i386 assembly version).
1.205 fefe 561: fixed FNM_PATHNAME in fnmatch
1.204 fefe 562: fix brk (the syscall was documented incorrectly in the Linux man page)
563: Thanks, Thomas Ogrisegg!
1.205 fefe 564: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 565: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 566: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 567:
1.164 fefe 568: 0.12:
569: more contributions from Frank Klemm.
1.165 fefe 570: iconv can now do UCS-2, too.
1.167 fefe 571: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 572: Lots of bug fixes, and several more i386 specific versions of common
573: routines to make them smaller.
1.168 fefe 574: add memmem (a GNU extension that looks useful)
1.170 fefe 575: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 576: add pivot_root syscall, %n for *scanf.
1.169 fefe 577: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 578: add Frank Klemm's optimized md5
1.172 fefe 579: add -Os option to diet (see diet.1).
1.173 fefe 580: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 581: add 32-bit uid/gid syscalls.
1.175 fefe 582: add rand48 (thanks, Johannes Kloos)
1.176 fefe 583: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 584: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
585: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
586: fix gethostent alias list termination. Major oops.
1.178 fefe 587: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 588: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 589: DNS will now properly signal errors and set h_errno.
590: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 591: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
592: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
593: external reference to a symbol that is only in the diet libc. So,
594: when you accidentally link a diet libc compiled object file against
595: glibc, the linker will barf. This will bloat your object files, but
596: you can remove all the references with "strip -R .note" from
597: the binaries in the end (which you should do anyway).
1.182 fefe 598: fix ARM unified syscall (select did not work).
1.183 fefe 599: add getpwent_r ala glibc and replace getpwent
600: do the same for getgrent and getspent
601: remove entlib (new code is smaller)
1.184 fefe 602: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 603: add getpwnam_r and getpwuid_r
1.186 fefe 604: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 605: Olaf muddled with the dynamic linker. It's a clean-room
606: implementation in the sense that it once worked for Olaf in a clean
607: room ;)
1.188 fefe 608: add if_nameindex and if_freenameindex.
609: fixed arm unified syscalls to work with current binutils (; is no
610: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 611: changed all st_[cma]time types to signed long so comparisons against
612: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 613: fixed two bugs regarding ungetc.
614: add getusershell, setusershell, endusershell (for vs_ftpd)
615: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 616: fixed strftime (was completely hosed)
1.192 fefe 617: added real make install target
1.164 fefe 618:
1.115 fefe 619: 0.11:
620: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 621: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 622: add floor, ceil and memchr prototypes.
623: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 624: cleaner errno vs __errno_location handling
625: add placeholder iconv (iconv_open will always return EINVAL)
626: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
627: initialization of getaddrinfo.
1.119 fefe 628: fix vsnprintf %X (printed lower case)
1.120 fefe 629: I wrote a new getopt. It appears to actually work (it is POSIX
630: compliant, it does not sort argv like the GNU version) and is only
631: a little over 300 bytes on x86.
1.121 fefe 632: Guillaume Cottenceau just wrote me that strncat should be even more
633: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 634: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 635: Fix regexec offset return. autoconf now believes that diet libc has
636: POSIX regular expressions.
1.123 fefe 637: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 638: Fix regular expression match for x* when there is no x at all.
1.125 fefe 639: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 640: Add %h to vsnprintf.
1.127 fefe 641: Add FAQ.
1.128 fefe 642: Make %h work for signed numbers and add %hh to vsnprintf.
643: initgroups ignored the group argument :-(
644: remove printf references and nested functions from glob.
1.129 fefe 645: added an errno in libpthread that will display a prominent linker
646: warning.
1.131 fefe 647: started getting rid of kernel headers. Big task! :-(
1.130 fefe 648: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 649: Olaf: added a lot of code in libdl (not yet complete), changed the
650: startup code to make it work with his libdl and ld.so (needs still work
651: too)
1.134 fefe 652: __dns_readstartfiles only took the first domain or search path.
653: Thanks, Anthony de Boer
1.133 olaf 654: Olaf: added clone and a new unified_syscall for PowerPC
655: also dynlinker is now available (i386 only at this time)
1.135 fefe 656: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 657: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 658: fixed word delimiters in regex (they looked for space, i.e. "," did
659: not work as delimiter)
1.138 fefe 660: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 661: added mkdtemp.
1.142 fefe 662: Uwe Ohse reported all of the following bugs:
663: ttyname should return 0 if !isatty.
664: realpath returns NULL if "." cannot be opened
665: putenv erroneously accepted (and mishandled) entries without "=".
666: popen returned 255 instead of 127 if /bin/sh could not be run.
667: fgetc did not set the internal EOF indicator on EOF.
668: bsearch contained an assumption about integer arithmetic overflow
669: behavior.
670: system did not set SIGCHLD and thus contained a race.
671: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 672: daemon did not check whether open returns an fd below 3
673: perror did not save errno.
1.144 olaf 674: Olaf: Peter Jones reported some problems with perror; strerror had the
675: same problem.
676: Peter also posted a patch to atexit/exit. With some modifications it is
677: now implemented.
1.145 fefe 678: Unbuffered stdio and ungetc can no longer be disabled. I will try to
679: implement part of it using ELF weak symbols.
1.146 fefe 680: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 681: Added overflow handling for strtoul and strtol.
1.149 fefe 682: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
683: it before falling back to DNS if enabled.
1.150 fefe 684: Added a littie backwards compatibility cruft for gpm (man, do these
685: sources stink!)
1.151 fefe 686: Added openpty.
1.152 fefe 687: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 688: Fix fseek return value.
1.155 fefe 689: Add dirname and basename.
1.156 fefe 690: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 691: Fixed getservent (did not allow _ and - in the aliases).
692: Thanks, Oden Eriksson
1.158 fefe 693: Added a float.h so configure believes we have ANSI header files.
694: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 695: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 696: scanf and printf function implementations
1.160 fefe 697: Imported a few more functions and optimizations from Frank Klemm (he
698: also rewrote dtostr to have more precision)
1.161 olaf 699: Olaf: checked in a new sig* function family (based on rt_sig*).
700: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 701: Made rudimentary iconv that can convert back and forth between
702: iso-8859-1, utf-8 and ucs-4 (for debugging).
703: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 704:
1.74 fefe 705: 0.10:
706: update getpagesize.
707: add personality.
1.75 fefe 708: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 709: add putchar (apparently arm-linux-gcc will substitute printf("\n")
710: with putchar('\n') behind your back...?!
1.77 fefe 711: import include/scsi/ from glibc.
1.78 fefe 712: add iopl.
1.80 fefe 713: add execl and sigdelset prototypes.
714: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 715: add RPC headers (no code yet).
1.82 fefe 716: add mlockall, munlockall
1.83 fefe 717: make "diet gcc foo.c" work.
718: added Sun RPC code and removed as many warnings as possible in a
719: heroic act of self-mutilation.
720: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 721: added getpass. mount from util-linux actually compiles now!
722: fix the sig*set routines. mount actually works now *bg*
723: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 724: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 725: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 726: add res_init.
727: add asprintf (ugh, what an ugly function).
1.89 fefe 728: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 729: add ut_name alias to ut_host in struct utmp.
730: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 731: add sysinfo, recvmsg, sendmsg.
1.93 fefe 732: add endmntent, getmntent, setmntent.
1.94 fefe 733: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 734: add setenv.
735: remove __restrict from mntent.h, add __restrict__ removal alias for
736: older gcc versions in sys/cdefs.h.
737: add rlim_t, sig_atomic_t declarations.
738: add sigsetjmp #define for __sigsetjmp (oops).
739: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 740: add a gruesome hack to printf floating point to accept %f and kludge
741: together support for %.2f. Don't look at the code, please!
1.98 fefe 742: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 743: imported fix for entlib by Jeff Garzik.
1.100 fefe 744: add glob implementation from Guillaume Cottenceau (Thanks!!)
745: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 746: add REG_ICASE and word start/end handling to my regular expressions.
747: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 748: wrap getcwd to comply to man page (the syscall returns the number of
749: bytes, not the buffer)
750: add realpath.
1.103 fefe 751: fix vfprintf.
1.104 fefe 752: fix *scanf %s zero termination.
753: add abs, labs, llabs.
1.105 fefe 754: add <sys/io.h>, ioperm syscall.
755: add flock to <sys/file.h>
1.106 fefe 756: fixes to bsearch and the regular expressions.
1.107 fefe 757: add fake herror.
1.108 fefe 758: add scandir and alphasort.
1.109 fefe 759: add killpg
1.110 fefe 760: implemented a gross hack to make libpthread compile when
761: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 762: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 763: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 764: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
765: for sending a patch.
1.114 fefe 766: add getserv*.
767: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
768: "search" from resolv.conf.
1.74 fefe 769:
1.73 fefe 770: 0.9:
1.65 fefe 771: fixed initgroups (oops)
1.66 fefe 772: Cleanup appending file open for stdio (thanks, James Antill)
773: imported vfprintf fix from James Antill.
1.67 fefe 774: add fnmatch
775: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 776: Olaf added character classes to *scanf.
1.69 fefe 777: Put object and library files into a separate directory (bin-$ARCH).
778: Add "cross" make target to make all architectures.
779: Add "diet" program and man page.
1.70 fefe 780: Add getgrnam, getgrgid
1.71 fefe 781: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 782: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 783:
1.64 fefe 784: 0.8:
1.34 fefe 785: vsnprintf(0,...) estimated the length of strings with a padding width
786: incorrectly.
1.35 fefe 787: new reboot() from Olaf.
1.36 fefe 788: added prototypes for getsockopt and setsockopt.
1.39 fefe 789: added experimental sem* and shm*
1.38 fefe 790: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 791: added setvbuf (only changes mode, not buffer)
1.41 fefe 792: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
793: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 794: added qsort() and bsearch(). Benchmark on 1000 random ints:
795: glibc: 679414 cycles qsort and 3352 cycles bsearch
796: diet libc: 300010 cycles qsort, 553 cycles bsearch
797: I have no idea why glibc is so slow.
1.43 fefe 798: added __isnan (references by libm.a from glibc).
799: added popen() and pclose(). Now the diet libc can link slsh (from
800: S-Lang!)
1.44 fefe 801: corrected usleep. It was more of an msleep until now.
1.45 fefe 802: corrected __dtostr (it looped when trying to format "0.0").
803: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 804: added ungetc (does it work?)
1.47 fefe 805: added inet_aton (yuck!)
1.50 fefe 806: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 807: added h_errno and __h_errno_location
808: added inet_ntoa
1.49 fefe 809: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 810: add bcopy, index, rindex macros
811: add isgraph and isxdigit
1.52 fefe 812: add strftime (ugh!!!)
1.53 olaf 813: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 814: Jeff Garzik contributed a spec file. I put it in contrib and hope
815: everbody knows what to do with it...
816: Olaf checked in a ton of libpthread stuff.
1.55 fefe 817: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 818: add large file backwards compatibility support (so gzip will run on
819: kernel 2.2 and 2.0)
1.57 fefe 820: added shutdown
1.58 fefe 821: added nice
822: added pseudo-locale support for is* (they are now weak aliases,
823: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
824: overwrite the default is* functions.
1.59 fefe 825: added liblatin1.a
1.60 fefe 826: added tzfile implementation (does it work for anyone else?)
1.61 fefe 827: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 828: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
829: Thanks!
1.63 fefe 830: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 831:
1.21 fefe 832: 0.7.2:
833: added several prototypes to already implemented functions and
834: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 835: added prototypes for process group and dup syscalls. Thanks to
836: Abraham again. He also contributed an implementation for daemon(),
837: an ugly BSD hack. I decided to diversify the lib/ directory a
838: little and now created a libugly/ directory for stuff like system()
839: and daemon() ;-)
840: added libstdio and moved all that stdio crap from lib/ there. The
841: idea is to start separating now what we will separate for shared
842: libraries anyway.
1.26 fefe 843: optimized x86 unified-syscall by Olaf.
1.27 fefe 844: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
845: limits.h instead)
846: added remove.c and enough cruft to limits.h to make it compile lzo,
847: lzop and bzip2.
1.28 fefe 848: added mktime, asctime_r, asctime and ctime (needed for gzip).
849: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 850: format some day (man tzfile, ugh!) :-(
1.29 fefe 851: added unlink prototype to unistd.h.
852: added gmtime and gmtime_r.
1.31 fefe 853: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 854: removed readdir glibc compatibility cruft.
1.31 fefe 855: removed stat glibc compatibility cruft.
1.32 fefe 856: oops, my fread was broken for pipes.
1.33 fefe 857: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 858:
1.9 fefe 859: 0.7.1:
1.11 fefe 860: optimized away the static arrays from __ltostr and __lltostr.
861: optimized away the static arrays (and more!) from strtoul and strtoull.
862: added system (by Olaf).
1.12 fefe 863: added tolower and toupper
1.13 fefe 864: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 865: added clone for mips (by Olaf).
866: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 867: added pause for all (by Olaf).
1.17 fefe 868: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 869: added isupper and islower.
870: added putc and putchar as macros.
1.17 fefe 871: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
872: insightful discussions and patches I partially used for the last three)
1.18 fefe 873: added getpriority and setpriority (also by Abraham)
1.19 fefe 874: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 875: oi, setjmp and longjmp were broken on other platforms, too!
876: Thanks to Sébastien Côté for reporting this.
1.9 fefe 877:
878: 0.7:
1.6 olaf 879: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 880: Initial dynamic loading glue for i386, also by Olaf.
881: We don't have a dynamic loader yet, so this is not yet usable.
882: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
883: vsprintf, writev, all by Olaf.
1.2 fefe 884: imported readdir fix from Guillaume. Mhh, can the kernel interface
885: really be this broken?
1.3 fefe 886: Found a kludgy way to detect whether the kernel includes define struct
887: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
888: not work for you, please tell me!
1.4 fefe 889: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 890: Fixed stdio line buffering. The code was already there but I forgot
891: to mark stdio and stdout as line buffered. This should really be
892: done dynamically using isatty, though.
1.8 fefe 893: Removed superfluous "if (1)" in execvp.c
1.1 cvs 894:
895: 0.6.14:
896: *scanf did not append the 0 byte for %s.
897: added creat and changed creat to call open directly instead of open64.
898: did for fread what 0.6.10 did for fwrite.
899: repaired buffered stdio a little (line buffering is still not
900: supported).
901: [All of these bugs have been reported by Guillaume. Thanks!]
902: added __pure__ to strchr and strrchr in <string.h>
903:
904: 0.6.13:
905: included COPYING to make clear that the diet libc is covered by the
906: GNU General Public License (and _not_ the LGPL). That means that
907: you need to obtain a license from me if you want to use the diet
908: libc in a proprietary program that you want to distribute.
909: The x86 unified syscall swapped arguments #4 and #5 and noone
910: noticed until now! Thanks to Guillaume Cottenceau for reporting
911: this!
912: The malloc had a subtle bug with small allocations that could cause
913: segfault. Guillaume reported it, Olaf fixed it.
914:
915: 0.6.12:
916: added assert, statfs and fstatfs
917: added include/net/if.h so fget compiles again.
918:
919: 0.6.11:
920: added putenv.
921:
922: 0.6.10:
923: fixed fwrite. It returned the number of bytes written, not the number
924: of records. Thanks to Albert D. Cahalan for pointing this out.
925: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
926: added brk and sbrk. harold@nb.com.sg made me do it.
927:
928: 0.6.9:
929: fixed execvp not to return on ENOENT
930: did for {open|read|close|seek|tell}dir what I did for stat before.
931: The glibc compatibility part is currently non-functional.
932: fixed white space handling in sscanf " (" would not match " (".
933: fixed printf to accept 'l' flag.
934: fixed getpwuid (ignored last line)
935:
936: 0.6.8:
937: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
938: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
939: added strlcpy and strlcat from OpenBSD.
940: added stat64, fstat64 and lstat64.
941: added endian.h and made ending of strlen.c endianness-aware
942: added string routines size tweak to dietfeatures.h. Most of the
943: string routines have been unrolled. This is up to three times as
944: fast but creates up to three times larger code. Now you can disable
945: the unrolling.
946: added sendfile.
947: I also added pread. It works on x86 and sparc but not on ppc and mips.
948: I have no idea what's going on. strace disagrees with the kernel.
949: Can anyone help? I asked the Linux kernel mailing list for help, too.
950: added a few aliases of the type __libc_open for open. nm on
951: libpthreads.so indicates that we will need them.
952:
953: 0.6.7:
954: the sources now compile without warnings with -Wall.
955: printf now prints "(null)" when %s is passed NULL. This can be
956: removed with WANT_NULL_PRINTF in dietfeatures.h
957: added vfprintf, execl, ttyname.
958: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
959: __dietfstat so they can use the normal kernel struct stat.
960: stat, lstat and fstat are now C wrappers that convert to the glibc
961: struct stat. So we can avoid that overhead for programs that use
962: dietlibc headers.
963:
964: 0.6.6:
965: changed the Makefiles so you can now set CFLAGS on the command line
966: added memccmp (analogous to memccpy) and strncmp.
967: Olaf fixed another bug in the sparc unified syscall.
968: Paul Clifford contributed a C version of his strlen.S that is much
969: more efficient than the previous strlen on all platforms! It also
970: looks like technology from Roswell. ;-}
971: added a "real" stdio. Well, almost. Please contribute!
972: added dietfeatures.h so you can remove features you don't need.
973: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
974: stdio now works with simple programs and minigzip from libz.
975: stdio uses some major trickery to avoid linking the stdio, stderr and
976: stdout (and reserving space for them) when they are not used.
977:
978: 0.6.5:
979: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
980: most of them bugs in the new header files, but also missing sigset
981: functions.
982: Paul Clifford contributed an assembly strlen.S for ARM and fixed
983: several bugs.
984: Fixed ppc/setjmp and mips/pipe.
985: Olaf contributed a new sparc unified syscall.
986:
987: 0.6.4:
988: declared is* static inline in getservent.
989: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
990: changed strlen to return 0 when passed NULL.
991: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
992: Scientist who actually implemented this without access to a MIPS
993: box, just from reading the architecture manual. And it worked out
994: of the box.
995: started a set of system includes, mainly so that I can use lcc and
996: my alpha-linux cross compiler (which is unable to cross-compile
997: glibc). diet libc can now be compiled without any include files
998: from a normal libc. The includes do declare more than diet libc
999: currently delivers and they are still far from complete for real
1000: applications.
1001: I will only add assembly versions that are smaller _and_ faster than
1002: the C version. Larger routines are only accepted if they are called
1003: very often and are substantially faster.
1004: added i386 assembly strchr, which is smaller and faster than the old
1005: version. It is, however, larger than the version contributed by
1006: proton (thanks, anyway).
1007: added i386 strlen (31% faster, 14% smaller)
1008: "make t" will now create a map file called "mapfile".
1009:
1010: 0.6.3:
1011: added sys_errlist, strerror and perror
1012: added isblank
1013: added atol
1014:
1015: 0.6.2:
1016: mmap for ARM didn't compile. Thanks, Paul!
1017:
1018: 0.6.1:
1019: split mmap into the architecture specific subdirectories.
1020: getenv now copes with environ==NULL, thanks Paul Clifford.
1021: Paul also contributed a smaller ARM startup code.
1022:
1023: 0.6:
1024: strcat returned the wrong result. Thanks, Dietz Pröpper.
1025: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1026: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1027: __dtostr does not work (I have no idea why!)
1028: The MIPS port now uses (much smaller) non-PIC code. That means that
1029: the applications you link against diet libc also have to be compiled
1030: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1031: Thanks to Ralf Bächle for helping me with this!
1032: I made subdirectories for the architectures and use VPATH to override
1033: VPATH so that make finds the source file automatically. That should
1034: simplify the sources greatly.
1035: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1036: ARM and MIPS now also have setjmp and longjmp
1037: "compile" and "load" are now make targets. Use them for djb programs.
1038: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1039: Again, contributed from Olaf. Great work!
1040:
1041: 0.5.12:
1042: printf also does signed numbers.
1043: If you don't use atexit, dietlibc now does not link exit, only _exit.
1044: *printf now correctly returns the number of bytes written.
1045: Olaf contributed experimental sscanf and vsscanf implementations.
1046: If passed NULL as buffer, snprintf will not write anything but still
1047: return the number of bytes it would have written.
1048: Initial MIPS port! (Oh, the agony!)
1049: No setjmp and longjmp support yet! Please contribute!
1050: I even implemented unified syscalls for MIPS. Still, MIPS code is
1051: almost twice the size of SPARC code. If anyone knows why: please
1052: tell me!
1053:
1054: 0.5.11:
1055: I implemented new unified syscalls for x86, sparc and ppc, this time based
1056: on .s files and not .c files, and I moved the syscalls into
1057: subdirectores to clean the dietlibc sources up a little.
1058: A binary consisting of printf("%s is %d\n","olaf",23) is now
1059: 2864 bytes on sparc
1060: 2488 bytes on intel
1061: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1062: to make a few more applications work.
1063: Olaf Dreesen also implemented some unified syscall stuff for x86.
1064: He discovered that with our unified syscall interface it actually
1065: costs <10 bytes total to make all system calls thread safe!
1066: I implemented atexit() (can register up to 4 callbacks).
1067: I implemented strtod and __dtostr (the opposite). Now we can add
1068: floating point support to vsnprintf and sscanf!
1069:
1070: 0.5.10:
1071: I actually saw that I can not only merge the errno handling code of
1072: the system calls on x86, I can also merge the rest (including the
1073: arguments) except for setting the system call number. All those
1074: system calls are now just a jump to a unified system call handler.
1075: I got rid of x86openclose again. The savings are substantial:
1076: chown from embutils went from 7664 to 7184 bytes!
1077: If I'd move the system call wrappers to assembly language, I could
1078: even reduce the alignment (does not matter since it's just a jump
1079: anyway) and get rid of the "ret" behind each jump (one byte per
1080: system call!)
1081:
1082: 0.5.9:
1083: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1084: fixed strdup
1085: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1086: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1087: (no signed integers, only strings and unsigned integers (but
1088: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1089: that code must be wonderful, I don't understand it at all *bg*)
1090: Olaf's printf does understand padding like in "%08d" and "%8d" and
1091: automatically pads pointers with '0'.
1092: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1093: Thanks to proton for inspiration on this.
1094: The new x86 start code also does not reference exit any more, thus saving
1095: 64 bytes for executables that don't call exit explicitly.
1096: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1097: Moved errno and environ to start.S, saving no byte binary size but
1098: speeding up compilation and slightly shortening dietlibc.a ;-)
1099: For x86: joined open and close into one assembler file, sharing the
1100: errno handling. This is a feasibility test and it actually saves a
1101: few bytes. I think I will reimplement the _syscall[1-6] macros on
1102: all platforms now to share the errno handling code for them.
1103:
1104: 0.5.8:
1105: fixed strchr to be able to look for 0.
1106:
1107: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1108: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1109: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1110: contributed by Olaf Dreesen)
1111:
1112: added execvp, getcwd
1113:
1114: fixed __xmknod
1115:
1116: Note: can it be that the ftw interface really is so broken that I
1117: cannot implement it without having to implement some searching data
1118: structure? I included an experimental ftw implementation that will
1119: not follow symlinks.
1120:
1121: 0.5.7:
1122: oops, if_nametoindex was broken!
1123:
1124: 0.5.6:
1125: ported to ppc-linux.
1126: fixed i386 sigsetjmp (I mistyped the function name)
1127: included sigjmp.c
1128:
1129: 0.5.5:
1130: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1131: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1132: I fixed it now.
1133: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1134: fixed readdir to use getdents and not the intel inline asm
1135:
1136: 0.5.4:
1137: ported to sparclinux (sparc32 only). Beware: does not work yet.
1138: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1139:
1140: 0.5.3:
1141: added tcsetattr and getenv to compile e3
1142:
1143: 0.5.2:
1144: added vhangup, tcgetattr, isatty and memcmp for fgetty
1145: (http://www.fefe.de/fgetty/)
1146: added localtime from uC-libc.
1147:
1148: 0.5.1:
1149: stat and friends actually work now. Yuck! Another case of
1150: translation between kernel and userland. Why can't the kernel
1151: people and the libc people simply agree on a standard?
1152: removed many unnecessary includes to speed up compilation.
1153: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1154: inlined socketcall to reduce code size.
1155: "load" and "compile" are examples for djb code.
1156:
1157: 0.5:
1158: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1159: each object file is now treated with "strip -x -R .note -R .comment"
1160: split each system call into a separate object file
1161: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1162:
1163: 0.4.1:
1164: oops, the strchr implementation was wrong. Thanks Jens Laas!
1165:
1166: 0.4:
1167: copied opendir and friends from uC-libc.
1168: added getservent and getservby* in gerservent.c
1169:
1170: 0.3:
1171: remove readdir system call
1172: added getdents system call
1173: added getpwnam/getpwuid implementation in getpwnam.c
1174: added a few string functions (in str*.c)
