350: there?)
1.284 fefe 351: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 352: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 353: upcoming AMD Hammer chips!). You can't even buy the chips yet and
354: the diet libc already supports it! Amazing ;-)
355: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 356: Andre sent a patch to add ARM profiling. He says it does not work
357: yet, but it's a start.
1.287 fefe 358: added getdents64 backwards compatibility and include it in large file
359: support #defines
1.288 fefe 360: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

392: adjusted lstat->lstat64 #define to make it work with function pointers
393: move __dietlibc__ #define from features.h to diet
1.267 fefe 394: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
395: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 396: Thomas also sent me profiling support (so far only on x86, but
397: profiling/PORTING describes what needs to be done for other
398: architectures)!
1.272 fefe 399: add contrib/dprof.c, also from Thomas.
1.269 fefe 400: Andreas Krennmair sent a patch to add the BSD regex interface to
401: libcompat
1.271 fefe 402: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 403: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 404: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 405: abort did not flush all stdio streams
1.277 fefe 406: fix some nasty regular expression bugs
407: write a stupid malloc checker (contrib/debug-realloc.c) to help me
408: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 409: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 410: fix DNS domain search
1.280 fefe 411: i386 memccpy exchanged esi and edi :-( I should do more checks before
412: accepting external code...
1.264 fefe 413:
1.244 fefe 414: 0.16:
415: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 416: Andre found two very embarassing bugs in my four lines of md5 glue.
417: I need to get more sleep.
1.247 fefe 418: Thanks Ogrisegg found that ptrace does not work as documented and
419: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 420: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
421: fix ptrace.h for S/390 and ARM
422: provide a PORTING document so we don't lose track of which file need
423: to be touched to port the diet libc to a new platform.
1.249 fefe 424: remove a few warnings
425: provide a prototype for usleep.
1.250 fefe 426: make __dtostr work on ARM by using long instead of long long.
427: Idea by Dirk Engling.
1.251 fefe 428: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 429: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 430: Kurt Garloff sent in patches to
431: fix struct termios on non-x86 architectures
1.254 fefe 432: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
433: create libcompat.a (and move daemon to it)
1.255 fefe 434: add getdelim and getline
435: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 436: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 437: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 438: Hans Lermen fixed i386/getenv.S
1.259 fefe 439: diet -Os no longer discards -fpic and -fno-pic

1.244 fefe 445:
1.224 fefe 446: 0.15:
1.225 fefe 447: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 448: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 449: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
450: thread-safe!
1.228 fefe 451: remove vfork and add alarm to dynamic syscalls.
452: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 453: The MD5 code generated unaligned accesses when passed an unaligned
454: pointer on little endian ARM and MIPS.
455: MIPS unified syscall didn't compile anymore.
456: Put up new mipsel target to cross compile for little endian mips.
457: The mips target will again explicitly set endianness to big endian.
458: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 459: Duh, when we removed return0, we broke tzset when the time zone parser
460: was disabled. Uwe Ohse noticed this. Thanks!
461: Fix gethostbyname to match host names case insensitively in /etc/hosts.
462: Oops, this was reported 6 weeks ago but I overlooked the email.
463: Thanks, Denis Rachal!
1.231 fefe 464: vsnprintf's zero termination was broken.
1.233 fefe 465: Uwe Ohse found a few more bugs:
466: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
467: does it correctly.
468: Make inet_aton use strtoul instead of strtol
469: fdopen would close the file descriptor if it could not malloc the
470: buffer.
471: strftime updates.
472: Make _FILE_OFFSET_BITS includes -Wundef clean
473: Andre found a typo in endian.h for big endian mips
1.234 fefe 474: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 475: strstr(whatever,"") returned NULL, not whatever. Found by a new test
476: suite entry for strstr that I wrote.
1.245 fefe 477: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 478: add <asm/sigcontext.h> for profiling support.
479: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 480: an i386 assembler getenv implementation (roughly half the size)
481: add grantpt, ptsname, unlockpt
1.236 fefe 482: add a getenv test suite entry.
1.238 fefe 483: Andre contributed an ARM assembler md5 implementation and he fixed mmap
484: on ARM.
485: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 486: getservent_r did not parse lines without aliases. Thanks, Jaroslav
487: Macodiseas!
1.240 fefe 488: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 489: removed annoying -Wconversion gcc switch
1.242 fefe 490: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 491: Kurt Garloff sent these diffs:
492: add fdatasync (and make it a pthread cancellation point)
493: numerous alpha issues, like using .quad instead of .long for
494: offsets, change strip to -strip in Makefile (so a failing strip does
495: not abort the make), try to be more friendly to the gcc 2.96 that
496: SuSE 7.1 AXP ships with.
1.224 fefe 497:
1.209 fefe 498: 0.14:
1.224 fefe 499: fix brk again (missing __brk, trivial oversight)
1.210 fefe 500: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
501: Thomas Ogrisegg!
1.211 fefe 502: Thomas also contributed a PA-RISC port including testandset, so
503: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 504: made the fake locale more believable.
505: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 506: moved _exit into the unified syscall on x86.
1.214 fefe 507: Uwe Ohse found many more bugs:
508: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
509: liblatin1 was more or less completely broken if you gave it chars as
510: arguments, not ints (signedness). execvp had a buffer overflow in
511: case a PATH element exceeded PATH_MAX, but it's not a security
512: problem since setuid programs need to set their path to some known
513: value anyway.
1.219 fefe 514: hasmntopt did not work with foo=bar style options
1.217 fefe 515: Uwe also improved ftw's stack usage.
1.214 fefe 516: Put movl instead of popl rationale in comment in i386/unified.S since
517: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 518: I discovered __attribute__((malloc)) and started using it. For gcc 3,
519: it improves the optimizer when functions return malloced pointers.
1.216 fefe 520: Steven Rostedt pointed out that my setvbuf was broken with regard to
521: size==0 and sent a patch to fix it.
1.218 fefe 522: Thomas Ogrisegg made setenv smaller.
1.220 olaf 523: Olaf: implemented the parisc clone and an atomic testandset, modified the
524: libpthread to respect the parisc UPgrowing stack. still non functional,
525: because the unified syscall uses errno :(
1.221 fefe 526: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 527: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
528: don't write anything which was no longer the case. It also
529: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 530: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 531:
1.193 fefe 532: 0.13:
1.194 fefe 533: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 534: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 535: Olaf: port to S/390!
1.463 leitner 536: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 537: res_query did not initialize last
1.199 fefe 538: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 539: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 540: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 541: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 542: rewrote __dtostr (it also has one more argument now)
1.205 fefe 543: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 544: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
545: fix strncat for the case where n == 0 (security implications?)
546: fix bsearch (it didn't find the very last element in the array, same
547: bug in both the C and the i386 assembly version).
1.205 fefe 548: fixed FNM_PATHNAME in fnmatch
1.204 fefe 549: fix brk (the syscall was documented incorrectly in the Linux man page)
550: Thanks, Thomas Ogrisegg!
1.205 fefe 551: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 552: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 553: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 554:
1.164 fefe 555: 0.12:
556: more contributions from Frank Klemm.
1.165 fefe 557: iconv can now do UCS-2, too.
1.167 fefe 558: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 559: Lots of bug fixes, and several more i386 specific versions of common
560: routines to make them smaller.
1.168 fefe 561: add memmem (a GNU extension that looks useful)
1.170 fefe 562: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 563: add pivot_root syscall, %n for *scanf.
1.169 fefe 564: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 565: add Frank Klemm's optimized md5
1.172 fefe 566: add -Os option to diet (see diet.1).
1.173 fefe 567: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 568: add 32-bit uid/gid syscalls.
1.175 fefe 569: add rand48 (thanks, Johannes Kloos)
1.176 fefe 570: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 571: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
572: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
573: fix gethostent alias list termination. Major oops.
1.178 fefe 574: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 575: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 576: DNS will now properly signal errors and set h_errno.
577: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 578: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
579: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
580: external reference to a symbol that is only in the diet libc. So,
581: when you accidentally link a diet libc compiled object file against
582: glibc, the linker will barf. This will bloat your object files, but
583: you can remove all the references with "strip -R .note" from
584: the binaries in the end (which you should do anyway).
1.182 fefe 585: fix ARM unified syscall (select did not work).
1.183 fefe 586: add getpwent_r ala glibc and replace getpwent
587: do the same for getgrent and getspent
588: remove entlib (new code is smaller)
1.184 fefe 589: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 590: add getpwnam_r and getpwuid_r
1.186 fefe 591: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 592: Olaf muddled with the dynamic linker. It's a clean-room
593: implementation in the sense that it once worked for Olaf in a clean
594: room ;)
1.188 fefe 595: add if_nameindex and if_freenameindex.
596: fixed arm unified syscalls to work with current binutils (; is no
597: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 598: changed all st_[cma]time types to signed long so comparisons against
599: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 600: fixed two bugs regarding ungetc.
601: add getusershell, setusershell, endusershell (for vs_ftpd)
602: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 603: fixed strftime (was completely hosed)
1.192 fefe 604: added real make install target
1.164 fefe 605:
1.115 fefe 606: 0.11:
607: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 608: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 609: add floor, ceil and memchr prototypes.
610: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 611: cleaner errno vs __errno_location handling
612: add placeholder iconv (iconv_open will always return EINVAL)
613: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
614: initialization of getaddrinfo.
1.119 fefe 615: fix vsnprintf %X (printed lower case)
1.120 fefe 616: I wrote a new getopt. It appears to actually work (it is POSIX
617: compliant, it does not sort argv like the GNU version) and is only
618: a little over 300 bytes on x86.
1.121 fefe 619: Guillaume Cottenceau just wrote me that strncat should be even more
620: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 621: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 622: Fix regexec offset return. autoconf now believes that diet libc has
623: POSIX regular expressions.
1.123 fefe 624: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 625: Fix regular expression match for x* when there is no x at all.
1.125 fefe 626: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 627: Add %h to vsnprintf.
1.127 fefe 628: Add FAQ.
1.128 fefe 629: Make %h work for signed numbers and add %hh to vsnprintf.
630: initgroups ignored the group argument :-(
631: remove printf references and nested functions from glob.
1.129 fefe 632: added an errno in libpthread that will display a prominent linker
633: warning.
1.131 fefe 634: started getting rid of kernel headers. Big task! :-(
1.130 fefe 635: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 636: Olaf: added a lot of code in libdl (not yet complete), changed the
637: startup code to make it work with his libdl and ld.so (needs still work
638: too)
1.134 fefe 639: __dns_readstartfiles only took the first domain or search path.
640: Thanks, Anthony de Boer
1.133 olaf 641: Olaf: added clone and a new unified_syscall for PowerPC
642: also dynlinker is now available (i386 only at this time)
1.135 fefe 643: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 644: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 645: fixed word delimiters in regex (they looked for space, i.e. "," did
646: not work as delimiter)
1.138 fefe 647: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 648: added mkdtemp.
1.142 fefe 649: Uwe Ohse reported all of the following bugs:
650: ttyname should return 0 if !isatty.
651: realpath returns NULL if "." cannot be opened
652: putenv erroneously accepted (and mishandled) entries without "=".
653: popen returned 255 instead of 127 if /bin/sh could not be run.
654: fgetc did not set the internal EOF indicator on EOF.
655: bsearch contained an assumption about integer arithmetic overflow
656: behavior.
657: system did not set SIGCHLD and thus contained a race.
658: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 659: daemon did not check whether open returns an fd below 3
660: perror did not save errno.
1.144 olaf 661: Olaf: Peter Jones reported some problems with perror; strerror had the
662: same problem.
663: Peter also posted a patch to atexit/exit. With some modifications it is
664: now implemented.
1.145 fefe 665: Unbuffered stdio and ungetc can no longer be disabled. I will try to
666: implement part of it using ELF weak symbols.
1.146 fefe 667: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 668: Added overflow handling for strtoul and strtol.
1.149 fefe 669: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
670: it before falling back to DNS if enabled.
1.150 fefe 671: Added a littie backwards compatibility cruft for gpm (man, do these
672: sources stink!)
1.151 fefe 673: Added openpty.
1.152 fefe 674: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 675: Fix fseek return value.
1.155 fefe 676: Add dirname and basename.
1.156 fefe 677: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 678: Fixed getservent (did not allow _ and - in the aliases).
679: Thanks, Oden Eriksson
1.158 fefe 680: Added a float.h so configure believes we have ANSI header files.
681: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 682: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 683: scanf and printf function implementations
1.160 fefe 684: Imported a few more functions and optimizations from Frank Klemm (he
685: also rewrote dtostr to have more precision)
1.161 olaf 686: Olaf: checked in a new sig* function family (based on rt_sig*).
687: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 688: Made rudimentary iconv that can convert back and forth between
689: iso-8859-1, utf-8 and ucs-4 (for debugging).
690: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 691:
1.74 fefe 692: 0.10:
693: update getpagesize.
694: add personality.
1.75 fefe 695: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 696: add putchar (apparently arm-linux-gcc will substitute printf("\n")
697: with putchar('\n') behind your back...?!
1.77 fefe 698: import include/scsi/ from glibc.
1.78 fefe 699: add iopl.
1.80 fefe 700: add execl and sigdelset prototypes.
701: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 702: add RPC headers (no code yet).
1.82 fefe 703: add mlockall, munlockall
1.83 fefe 704: make "diet gcc foo.c" work.
705: added Sun RPC code and removed as many warnings as possible in a
706: heroic act of self-mutilation.
707: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 708: added getpass. mount from util-linux actually compiles now!
709: fix the sig*set routines. mount actually works now *bg*
710: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 711: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 712: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 713: add res_init.
714: add asprintf (ugh, what an ugly function).
1.89 fefe 715: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 716: add ut_name alias to ut_host in struct utmp.
717: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 718: add sysinfo, recvmsg, sendmsg.
1.93 fefe 719: add endmntent, getmntent, setmntent.
1.94 fefe 720: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 721: add setenv.
722: remove __restrict from mntent.h, add __restrict__ removal alias for
723: older gcc versions in sys/cdefs.h.
724: add rlim_t, sig_atomic_t declarations.
725: add sigsetjmp #define for __sigsetjmp (oops).
726: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 727: add a gruesome hack to printf floating point to accept %f and kludge
728: together support for %.2f. Don't look at the code, please!
1.98 fefe 729: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 730: imported fix for entlib by Jeff Garzik.
1.100 fefe 731: add glob implementation from Guillaume Cottenceau (Thanks!!)
732: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 733: add REG_ICASE and word start/end handling to my regular expressions.
734: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 735: wrap getcwd to comply to man page (the syscall returns the number of
736: bytes, not the buffer)
737: add realpath.
1.103 fefe 738: fix vfprintf.
1.104 fefe 739: fix *scanf %s zero termination.
740: add abs, labs, llabs.
1.105 fefe 741: add <sys/io.h>, ioperm syscall.
742: add flock to <sys/file.h>
1.106 fefe 743: fixes to bsearch and the regular expressions.
1.107 fefe 744: add fake herror.
1.108 fefe 745: add scandir and alphasort.
1.109 fefe 746: add killpg
1.110 fefe 747: implemented a gross hack to make libpthread compile when
748: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 749: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 750: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 751: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
752: for sending a patch.
1.114 fefe 753: add getserv*.
754: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
755: "search" from resolv.conf.
1.74 fefe 756:
1.73 fefe 757: 0.9:
1.65 fefe 758: fixed initgroups (oops)
1.66 fefe 759: Cleanup appending file open for stdio (thanks, James Antill)
760: imported vfprintf fix from James Antill.
1.67 fefe 761: add fnmatch
762: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 763: Olaf added character classes to *scanf.
1.69 fefe 764: Put object and library files into a separate directory (bin-$ARCH).
765: Add "cross" make target to make all architectures.
766: Add "diet" program and man page.
1.70 fefe 767: Add getgrnam, getgrgid
1.71 fefe 768: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 769: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 770:
1.64 fefe 771: 0.8:
1.34 fefe 772: vsnprintf(0,...) estimated the length of strings with a padding width
773: incorrectly.
1.35 fefe 774: new reboot() from Olaf.
1.36 fefe 775: added prototypes for getsockopt and setsockopt.
1.39 fefe 776: added experimental sem* and shm*
1.38 fefe 777: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 778: added setvbuf (only changes mode, not buffer)
1.41 fefe 779: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
780: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 781: added qsort() and bsearch(). Benchmark on 1000 random ints:
782: glibc: 679414 cycles qsort and 3352 cycles bsearch
783: diet libc: 300010 cycles qsort, 553 cycles bsearch
784: I have no idea why glibc is so slow.
1.43 fefe 785: added __isnan (references by libm.a from glibc).
786: added popen() and pclose(). Now the diet libc can link slsh (from
787: S-Lang!)
1.44 fefe 788: corrected usleep. It was more of an msleep until now.
1.45 fefe 789: corrected __dtostr (it looped when trying to format "0.0").
790: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 791: added ungetc (does it work?)
1.47 fefe 792: added inet_aton (yuck!)
1.50 fefe 793: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 794: added h_errno and __h_errno_location
795: added inet_ntoa
1.49 fefe 796: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 797: add bcopy, index, rindex macros
798: add isgraph and isxdigit
1.52 fefe 799: add strftime (ugh!!!)
1.53 olaf 800: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 801: Jeff Garzik contributed a spec file. I put it in contrib and hope
802: everbody knows what to do with it...
803: Olaf checked in a ton of libpthread stuff.
1.55 fefe 804: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 805: add large file backwards compatibility support (so gzip will run on
806: kernel 2.2 and 2.0)
1.57 fefe 807: added shutdown
1.58 fefe 808: added nice
809: added pseudo-locale support for is* (they are now weak aliases,
810: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
811: overwrite the default is* functions.
1.59 fefe 812: added liblatin1.a
1.60 fefe 813: added tzfile implementation (does it work for anyone else?)
1.61 fefe 814: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 815: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
816: Thanks!
1.63 fefe 817: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 818:
1.21 fefe 819: 0.7.2:
820: added several prototypes to already implemented functions and
821: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 822: added prototypes for process group and dup syscalls. Thanks to
823: Abraham again. He also contributed an implementation for daemon(),
824: an ugly BSD hack. I decided to diversify the lib/ directory a
825: little and now created a libugly/ directory for stuff like system()
826: and daemon() ;-)
827: added libstdio and moved all that stdio crap from lib/ there. The
828: idea is to start separating now what we will separate for shared
829: libraries anyway.
1.26 fefe 830: optimized x86 unified-syscall by Olaf.
1.27 fefe 831: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
832: limits.h instead)
833: added remove.c and enough cruft to limits.h to make it compile lzo,
834: lzop and bzip2.
1.28 fefe 835: added mktime, asctime_r, asctime and ctime (needed for gzip).
836: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 837: format some day (man tzfile, ugh!) :-(
1.29 fefe 838: added unlink prototype to unistd.h.
839: added gmtime and gmtime_r.
1.31 fefe 840: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 841: removed readdir glibc compatibility cruft.
1.31 fefe 842: removed stat glibc compatibility cruft.
1.32 fefe 843: oops, my fread was broken for pipes.
1.33 fefe 844: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 845:
1.9 fefe 846: 0.7.1:
1.11 fefe 847: optimized away the static arrays from __ltostr and __lltostr.
848: optimized away the static arrays (and more!) from strtoul and strtoull.
849: added system (by Olaf).
1.12 fefe 850: added tolower and toupper
1.13 fefe 851: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 852: added clone for mips (by Olaf).
853: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 854: added pause for all (by Olaf).
1.17 fefe 855: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 856: added isupper and islower.
857: added putc and putchar as macros.
1.17 fefe 858: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
859: insightful discussions and patches I partially used for the last three)
1.18 fefe 860: added getpriority and setpriority (also by Abraham)
1.19 fefe 861: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 862: oi, setjmp and longjmp were broken on other platforms, too!
863: Thanks to Sébastien Côté for reporting this.
1.9 fefe 864:
865: 0.7:
1.6 olaf 866: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 867: Initial dynamic loading glue for i386, also by Olaf.
868: We don't have a dynamic loader yet, so this is not yet usable.
869: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
870: vsprintf, writev, all by Olaf.
1.2 fefe 871: imported readdir fix from Guillaume. Mhh, can the kernel interface
872: really be this broken?
1.3 fefe 873: Found a kludgy way to detect whether the kernel includes define struct
874: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
875: not work for you, please tell me!
1.4 fefe 876: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 877: Fixed stdio line buffering. The code was already there but I forgot
878: to mark stdio and stdout as line buffered. This should really be
879: done dynamically using isatty, though.
1.8 fefe 880: Removed superfluous "if (1)" in execvp.c
1.1 cvs 881:
882: 0.6.14:
883: *scanf did not append the 0 byte for %s.
884: added creat and changed creat to call open directly instead of open64.
885: did for fread what 0.6.10 did for fwrite.
886: repaired buffered stdio a little (line buffering is still not
887: supported).
888: [All of these bugs have been reported by Guillaume. Thanks!]
889: added __pure__ to strchr and strrchr in <string.h>
890:
891: 0.6.13:
892: included COPYING to make clear that the diet libc is covered by the
893: GNU General Public License (and _not_ the LGPL). That means that
894: you need to obtain a license from me if you want to use the diet
895: libc in a proprietary program that you want to distribute.
896: The x86 unified syscall swapped arguments #4 and #5 and noone
897: noticed until now! Thanks to Guillaume Cottenceau for reporting
898: this!
899: The malloc had a subtle bug with small allocations that could cause
900: segfault. Guillaume reported it, Olaf fixed it.
901:
902: 0.6.12:
903: added assert, statfs and fstatfs
904: added include/net/if.h so fget compiles again.
905:
906: 0.6.11:
907: added putenv.
908:
909: 0.6.10:
910: fixed fwrite. It returned the number of bytes written, not the number
911: of records. Thanks to Albert D. Cahalan for pointing this out.
912: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
913: added brk and sbrk. harold@nb.com.sg made me do it.
914:
915: 0.6.9:
916: fixed execvp not to return on ENOENT
917: did for {open|read|close|seek|tell}dir what I did for stat before.
918: The glibc compatibility part is currently non-functional.
919: fixed white space handling in sscanf " (" would not match " (".
920: fixed printf to accept 'l' flag.
921: fixed getpwuid (ignored last line)
922:
923: 0.6.8:
924: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
925: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
926: added strlcpy and strlcat from OpenBSD.
927: added stat64, fstat64 and lstat64.
928: added endian.h and made ending of strlen.c endianness-aware
929: added string routines size tweak to dietfeatures.h. Most of the
930: string routines have been unrolled. This is up to three times as
931: fast but creates up to three times larger code. Now you can disable
932: the unrolling.
933: added sendfile.
934: I also added pread. It works on x86 and sparc but not on ppc and mips.
935: I have no idea what's going on. strace disagrees with the kernel.
936: Can anyone help? I asked the Linux kernel mailing list for help, too.
937: added a few aliases of the type __libc_open for open. nm on
938: libpthreads.so indicates that we will need them.
939:
940: 0.6.7:
941: the sources now compile without warnings with -Wall.
942: printf now prints "(null)" when %s is passed NULL. This can be
943: removed with WANT_NULL_PRINTF in dietfeatures.h
944: added vfprintf, execl, ttyname.
945: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
946: __dietfstat so they can use the normal kernel struct stat.
947: stat, lstat and fstat are now C wrappers that convert to the glibc
948: struct stat. So we can avoid that overhead for programs that use
949: dietlibc headers.
950:
951: 0.6.6:
952: changed the Makefiles so you can now set CFLAGS on the command line
953: added memccmp (analogous to memccpy) and strncmp.
954: Olaf fixed another bug in the sparc unified syscall.
955: Paul Clifford contributed a C version of his strlen.S that is much
956: more efficient than the previous strlen on all platforms! It also
957: looks like technology from Roswell. ;-}
958: added a "real" stdio. Well, almost. Please contribute!
959: added dietfeatures.h so you can remove features you don't need.
960: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
961: stdio now works with simple programs and minigzip from libz.
962: stdio uses some major trickery to avoid linking the stdio, stderr and
963: stdout (and reserving space for them) when they are not used.
964:
965: 0.6.5:
966: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
967: most of them bugs in the new header files, but also missing sigset
968: functions.
969: Paul Clifford contributed an assembly strlen.S for ARM and fixed
970: several bugs.
971: Fixed ppc/setjmp and mips/pipe.
972: Olaf contributed a new sparc unified syscall.
973:
974: 0.6.4:
975: declared is* static inline in getservent.
976: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
977: changed strlen to return 0 when passed NULL.
978: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
979: Scientist who actually implemented this without access to a MIPS
980: box, just from reading the architecture manual. And it worked out
981: of the box.
982: started a set of system includes, mainly so that I can use lcc and
983: my alpha-linux cross compiler (which is unable to cross-compile
984: glibc). diet libc can now be compiled without any include files
985: from a normal libc. The includes do declare more than diet libc
986: currently delivers and they are still far from complete for real
987: applications.
988: I will only add assembly versions that are smaller _and_ faster than
989: the C version. Larger routines are only accepted if they are called
990: very often and are substantially faster.
991: added i386 assembly strchr, which is smaller and faster than the old
992: version. It is, however, larger than the version contributed by
993: proton (thanks, anyway).
994: added i386 strlen (31% faster, 14% smaller)
995: "make t" will now create a map file called "mapfile".
996:
997: 0.6.3:
998: added sys_errlist, strerror and perror
999: added isblank
1000: added atol
1001:
1002: 0.6.2:
1003: mmap for ARM didn't compile. Thanks, Paul!
1004:
1005: 0.6.1:
1006: split mmap into the architecture specific subdirectories.
1007: getenv now copes with environ==NULL, thanks Paul Clifford.
1008: Paul also contributed a smaller ARM startup code.
1009:
1010: 0.6:
1011: strcat returned the wrong result. Thanks, Dietz Pröpper.
1012: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1013: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1014: __dtostr does not work (I have no idea why!)
1015: The MIPS port now uses (much smaller) non-PIC code. That means that
1016: the applications you link against diet libc also have to be compiled
1017: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1018: Thanks to Ralf Bächle for helping me with this!
1019: I made subdirectories for the architectures and use VPATH to override
1020: VPATH so that make finds the source file automatically. That should
1021: simplify the sources greatly.
1022: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1023: ARM and MIPS now also have setjmp and longjmp
1024: "compile" and "load" are now make targets. Use them for djb programs.
1025: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1026: Again, contributed from Olaf. Great work!
1027:
1028: 0.5.12:
1029: printf also does signed numbers.
1030: If you don't use atexit, dietlibc now does not link exit, only _exit.
1031: *printf now correctly returns the number of bytes written.
1032: Olaf contributed experimental sscanf and vsscanf implementations.
1033: If passed NULL as buffer, snprintf will not write anything but still
1034: return the number of bytes it would have written.
1035: Initial MIPS port! (Oh, the agony!)
1036: No setjmp and longjmp support yet! Please contribute!
1037: I even implemented unified syscalls for MIPS. Still, MIPS code is
1038: almost twice the size of SPARC code. If anyone knows why: please
1039: tell me!
1040:
1041: 0.5.11:
1042: I implemented new unified syscalls for x86, sparc and ppc, this time based
1043: on .s files and not .c files, and I moved the syscalls into
1044: subdirectores to clean the dietlibc sources up a little.
1045: A binary consisting of printf("%s is %d\n","olaf",23) is now
1046: 2864 bytes on sparc
1047: 2488 bytes on intel
1048: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1049: to make a few more applications work.
1050: Olaf Dreesen also implemented some unified syscall stuff for x86.
1051: He discovered that with our unified syscall interface it actually
1052: costs <10 bytes total to make all system calls thread safe!
1053: I implemented atexit() (can register up to 4 callbacks).
1054: I implemented strtod and __dtostr (the opposite). Now we can add
1055: floating point support to vsnprintf and sscanf!
1056:
1057: 0.5.10:
1058: I actually saw that I can not only merge the errno handling code of
1059: the system calls on x86, I can also merge the rest (including the
1060: arguments) except for setting the system call number. All those
1061: system calls are now just a jump to a unified system call handler.
1062: I got rid of x86openclose again. The savings are substantial:
1063: chown from embutils went from 7664 to 7184 bytes!
1064: If I'd move the system call wrappers to assembly language, I could
1065: even reduce the alignment (does not matter since it's just a jump
1066: anyway) and get rid of the "ret" behind each jump (one byte per
1067: system call!)
1068:
1069: 0.5.9:
1070: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1071: fixed strdup
1072: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1073: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1074: (no signed integers, only strings and unsigned integers (but
1075: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1076: that code must be wonderful, I don't understand it at all *bg*)
1077: Olaf's printf does understand padding like in "%08d" and "%8d" and
1078: automatically pads pointers with '0'.
1079: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1080: Thanks to proton for inspiration on this.
1081: The new x86 start code also does not reference exit any more, thus saving
1082: 64 bytes for executables that don't call exit explicitly.
1083: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1084: Moved errno and environ to start.S, saving no byte binary size but
1085: speeding up compilation and slightly shortening dietlibc.a ;-)
1086: For x86: joined open and close into one assembler file, sharing the
1087: errno handling. This is a feasibility test and it actually saves a
1088: few bytes. I think I will reimplement the _syscall[1-6] macros on
1089: all platforms now to share the errno handling code for them.
1090:
1091: 0.5.8:
1092: fixed strchr to be able to look for 0.
1093:
1094: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1095: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1096: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1097: contributed by Olaf Dreesen)
1098:
1099: added execvp, getcwd
1100:
1101: fixed __xmknod
1102:
1103: Note: can it be that the ftw interface really is so broken that I
1104: cannot implement it without having to implement some searching data
1105: structure? I included an experimental ftw implementation that will
1106: not follow symlinks.
1107:
1108: 0.5.7:
1109: oops, if_nametoindex was broken!
1110:
1111: 0.5.6:
1112: ported to ppc-linux.
1113: fixed i386 sigsetjmp (I mistyped the function name)
1114: included sigjmp.c
1115:
1116: 0.5.5:
1117: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1118: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1119: I fixed it now.
1120: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1121: fixed readdir to use getdents and not the intel inline asm
1122:
1123: 0.5.4:
1124: ported to sparclinux (sparc32 only). Beware: does not work yet.
1125: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1126:
1127: 0.5.3:
1128: added tcsetattr and getenv to compile e3
1129:
1130: 0.5.2:
1131: added vhangup, tcgetattr, isatty and memcmp for fgetty
1132: (http://www.fefe.de/fgetty/)
1133: added localtime from uC-libc.
1134:
1135: 0.5.1:
1136: stat and friends actually work now. Yuck! Another case of
1137: translation between kernel and userland. Why can't the kernel
1138: people and the libc people simply agree on a standard?
1139: removed many unnecessary includes to speed up compilation.
1140: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1141: inlined socketcall to reduce code size.
1142: "load" and "compile" are examples for djb code.
1143:
1144: 0.5:
1145: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1146: each object file is now treated with "strip -x -R .note -R .comment"
1147: split each system call into a separate object file
1148: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1149:
1150: 0.4.1:
1151: oops, the strchr implementation was wrong. Thanks Jens Laas!
1152:
1153: 0.4:
1154: copied opendir and friends from uC-libc.
1155: added getservent and getservby* in gerservent.c
1156:
1157: 0.3:
1158: remove readdir system call
1159: added getdents system call
1160: added getpwnam/getpwuid implementation in getpwnam.c
1161: added a few string functions (in str*.c)
