352: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 353: add libm2.s from contrib to i386 (oops, how long has it been sitting
354: there?)
1.284 fefe 355: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 356: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 357: upcoming AMD Hammer chips!). You can't even buy the chips yet and
358: the diet libc already supports it! Amazing ;-)
359: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 360: Andre sent a patch to add ARM profiling. He says it does not work
361: yet, but it's a start.
1.287 fefe 362: added getdents64 backwards compatibility and include it in large file
363: support #defines
1.288 fefe 364: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

396: adjusted lstat->lstat64 #define to make it work with function pointers
397: move __dietlibc__ #define from features.h to diet
1.267 fefe 398: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
399: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 400: Thomas also sent me profiling support (so far only on x86, but
401: profiling/PORTING describes what needs to be done for other
402: architectures)!
1.272 fefe 403: add contrib/dprof.c, also from Thomas.
1.269 fefe 404: Andreas Krennmair sent a patch to add the BSD regex interface to
405: libcompat
1.271 fefe 406: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 407: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 408: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 409: abort did not flush all stdio streams
1.277 fefe 410: fix some nasty regular expression bugs
411: write a stupid malloc checker (contrib/debug-realloc.c) to help me
412: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 413: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 414: fix DNS domain search
1.280 fefe 415: i386 memccpy exchanged esi and edi :-( I should do more checks before
416: accepting external code...
1.264 fefe 417:
1.244 fefe 418: 0.16:
419: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 420: Andre found two very embarassing bugs in my four lines of md5 glue.
421: I need to get more sleep.
1.247 fefe 422: Thanks Ogrisegg found that ptrace does not work as documented and
423: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 424: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
425: fix ptrace.h for S/390 and ARM
426: provide a PORTING document so we don't lose track of which file need
427: to be touched to port the diet libc to a new platform.
1.249 fefe 428: remove a few warnings
429: provide a prototype for usleep.
1.250 fefe 430: make __dtostr work on ARM by using long instead of long long.
431: Idea by Dirk Engling.
1.251 fefe 432: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 433: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 434: Kurt Garloff sent in patches to
435: fix struct termios on non-x86 architectures
1.254 fefe 436: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
437: create libcompat.a (and move daemon to it)
1.255 fefe 438: add getdelim and getline
439: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 440: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 441: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 442: Hans Lermen fixed i386/getenv.S
1.259 fefe 443: diet -Os no longer discards -fpic and -fno-pic

1.244 fefe 449:
1.224 fefe 450: 0.15:
1.225 fefe 451: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 452: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 453: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
454: thread-safe!
1.228 fefe 455: remove vfork and add alarm to dynamic syscalls.
456: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 457: The MD5 code generated unaligned accesses when passed an unaligned
458: pointer on little endian ARM and MIPS.
459: MIPS unified syscall didn't compile anymore.
460: Put up new mipsel target to cross compile for little endian mips.
461: The mips target will again explicitly set endianness to big endian.
462: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 463: Duh, when we removed return0, we broke tzset when the time zone parser
464: was disabled. Uwe Ohse noticed this. Thanks!
465: Fix gethostbyname to match host names case insensitively in /etc/hosts.
466: Oops, this was reported 6 weeks ago but I overlooked the email.
467: Thanks, Denis Rachal!
1.231 fefe 468: vsnprintf's zero termination was broken.
1.233 fefe 469: Uwe Ohse found a few more bugs:
470: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
471: does it correctly.
472: Make inet_aton use strtoul instead of strtol
473: fdopen would close the file descriptor if it could not malloc the
474: buffer.
475: strftime updates.
476: Make _FILE_OFFSET_BITS includes -Wundef clean
477: Andre found a typo in endian.h for big endian mips
1.234 fefe 478: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 479: strstr(whatever,"") returned NULL, not whatever. Found by a new test
480: suite entry for strstr that I wrote.
1.245 fefe 481: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 482: add <asm/sigcontext.h> for profiling support.
483: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 484: an i386 assembler getenv implementation (roughly half the size)
485: add grantpt, ptsname, unlockpt
1.236 fefe 486: add a getenv test suite entry.
1.238 fefe 487: Andre contributed an ARM assembler md5 implementation and he fixed mmap
488: on ARM.
489: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 490: getservent_r did not parse lines without aliases. Thanks, Jaroslav
491: Macodiseas!
1.240 fefe 492: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 493: removed annoying -Wconversion gcc switch
1.242 fefe 494: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 495: Kurt Garloff sent these diffs:
496: add fdatasync (and make it a pthread cancellation point)
497: numerous alpha issues, like using .quad instead of .long for
498: offsets, change strip to -strip in Makefile (so a failing strip does
499: not abort the make), try to be more friendly to the gcc 2.96 that
500: SuSE 7.1 AXP ships with.
1.224 fefe 501:
1.209 fefe 502: 0.14:
1.224 fefe 503: fix brk again (missing __brk, trivial oversight)
1.210 fefe 504: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
505: Thomas Ogrisegg!
1.211 fefe 506: Thomas also contributed a PA-RISC port including testandset, so
507: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 508: made the fake locale more believable.
509: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 510: moved _exit into the unified syscall on x86.
1.214 fefe 511: Uwe Ohse found many more bugs:
512: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
513: liblatin1 was more or less completely broken if you gave it chars as
514: arguments, not ints (signedness). execvp had a buffer overflow in
515: case a PATH element exceeded PATH_MAX, but it's not a security
516: problem since setuid programs need to set their path to some known
517: value anyway.
1.219 fefe 518: hasmntopt did not work with foo=bar style options
1.217 fefe 519: Uwe also improved ftw's stack usage.
1.214 fefe 520: Put movl instead of popl rationale in comment in i386/unified.S since
521: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 522: I discovered __attribute__((malloc)) and started using it. For gcc 3,
523: it improves the optimizer when functions return malloced pointers.
1.216 fefe 524: Steven Rostedt pointed out that my setvbuf was broken with regard to
525: size==0 and sent a patch to fix it.
1.218 fefe 526: Thomas Ogrisegg made setenv smaller.
1.220 olaf 527: Olaf: implemented the parisc clone and an atomic testandset, modified the
528: libpthread to respect the parisc UPgrowing stack. still non functional,
529: because the unified syscall uses errno :(
1.221 fefe 530: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 531: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
532: don't write anything which was no longer the case. It also
533: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 534: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 535:
1.193 fefe 536: 0.13:
1.194 fefe 537: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 538: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 539: Olaf: port to S/390!
1.463 leitner 540: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 541: res_query did not initialize last
1.199 fefe 542: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 543: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 544: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 545: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 546: rewrote __dtostr (it also has one more argument now)
1.205 fefe 547: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 548: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
549: fix strncat for the case where n == 0 (security implications?)
550: fix bsearch (it didn't find the very last element in the array, same
551: bug in both the C and the i386 assembly version).
1.205 fefe 552: fixed FNM_PATHNAME in fnmatch
1.204 fefe 553: fix brk (the syscall was documented incorrectly in the Linux man page)
554: Thanks, Thomas Ogrisegg!
1.205 fefe 555: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 556: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 557: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 558:
1.164 fefe 559: 0.12:
560: more contributions from Frank Klemm.
1.165 fefe 561: iconv can now do UCS-2, too.
1.167 fefe 562: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 563: Lots of bug fixes, and several more i386 specific versions of common
564: routines to make them smaller.
1.168 fefe 565: add memmem (a GNU extension that looks useful)
1.170 fefe 566: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 567: add pivot_root syscall, %n for *scanf.
1.169 fefe 568: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 569: add Frank Klemm's optimized md5
1.172 fefe 570: add -Os option to diet (see diet.1).
1.173 fefe 571: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 572: add 32-bit uid/gid syscalls.
1.175 fefe 573: add rand48 (thanks, Johannes Kloos)
1.176 fefe 574: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 575: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
576: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
577: fix gethostent alias list termination. Major oops.
1.178 fefe 578: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 579: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 580: DNS will now properly signal errors and set h_errno.
581: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 582: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
583: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
584: external reference to a symbol that is only in the diet libc. So,
585: when you accidentally link a diet libc compiled object file against
586: glibc, the linker will barf. This will bloat your object files, but
587: you can remove all the references with "strip -R .note" from
588: the binaries in the end (which you should do anyway).
1.182 fefe 589: fix ARM unified syscall (select did not work).
1.183 fefe 590: add getpwent_r ala glibc and replace getpwent
591: do the same for getgrent and getspent
592: remove entlib (new code is smaller)
1.184 fefe 593: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 594: add getpwnam_r and getpwuid_r
1.186 fefe 595: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 596: Olaf muddled with the dynamic linker. It's a clean-room
597: implementation in the sense that it once worked for Olaf in a clean
598: room ;)
1.188 fefe 599: add if_nameindex and if_freenameindex.
600: fixed arm unified syscalls to work with current binutils (; is no
601: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 602: changed all st_[cma]time types to signed long so comparisons against
603: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 604: fixed two bugs regarding ungetc.
605: add getusershell, setusershell, endusershell (for vs_ftpd)
606: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 607: fixed strftime (was completely hosed)
1.192 fefe 608: added real make install target
1.164 fefe 609:
1.115 fefe 610: 0.11:
611: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 612: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 613: add floor, ceil and memchr prototypes.
614: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 615: cleaner errno vs __errno_location handling
616: add placeholder iconv (iconv_open will always return EINVAL)
617: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
618: initialization of getaddrinfo.
1.119 fefe 619: fix vsnprintf %X (printed lower case)
1.120 fefe 620: I wrote a new getopt. It appears to actually work (it is POSIX
621: compliant, it does not sort argv like the GNU version) and is only
622: a little over 300 bytes on x86.
1.121 fefe 623: Guillaume Cottenceau just wrote me that strncat should be even more
624: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 625: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 626: Fix regexec offset return. autoconf now believes that diet libc has
627: POSIX regular expressions.
1.123 fefe 628: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 629: Fix regular expression match for x* when there is no x at all.
1.125 fefe 630: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 631: Add %h to vsnprintf.
1.127 fefe 632: Add FAQ.
1.128 fefe 633: Make %h work for signed numbers and add %hh to vsnprintf.
634: initgroups ignored the group argument :-(
635: remove printf references and nested functions from glob.
1.129 fefe 636: added an errno in libpthread that will display a prominent linker
637: warning.
1.131 fefe 638: started getting rid of kernel headers. Big task! :-(
1.130 fefe 639: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 640: Olaf: added a lot of code in libdl (not yet complete), changed the
641: startup code to make it work with his libdl and ld.so (needs still work
642: too)
1.134 fefe 643: __dns_readstartfiles only took the first domain or search path.
644: Thanks, Anthony de Boer
1.133 olaf 645: Olaf: added clone and a new unified_syscall for PowerPC
646: also dynlinker is now available (i386 only at this time)
1.135 fefe 647: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 648: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 649: fixed word delimiters in regex (they looked for space, i.e. "," did
650: not work as delimiter)
1.138 fefe 651: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 652: added mkdtemp.
1.142 fefe 653: Uwe Ohse reported all of the following bugs:
654: ttyname should return 0 if !isatty.
655: realpath returns NULL if "." cannot be opened
656: putenv erroneously accepted (and mishandled) entries without "=".
657: popen returned 255 instead of 127 if /bin/sh could not be run.
658: fgetc did not set the internal EOF indicator on EOF.
659: bsearch contained an assumption about integer arithmetic overflow
660: behavior.
661: system did not set SIGCHLD and thus contained a race.
662: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 663: daemon did not check whether open returns an fd below 3
664: perror did not save errno.
1.144 olaf 665: Olaf: Peter Jones reported some problems with perror; strerror had the
666: same problem.
667: Peter also posted a patch to atexit/exit. With some modifications it is
668: now implemented.
1.145 fefe 669: Unbuffered stdio and ungetc can no longer be disabled. I will try to
670: implement part of it using ELF weak symbols.
1.146 fefe 671: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 672: Added overflow handling for strtoul and strtol.
1.149 fefe 673: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
674: it before falling back to DNS if enabled.
1.150 fefe 675: Added a littie backwards compatibility cruft for gpm (man, do these
676: sources stink!)
1.151 fefe 677: Added openpty.
1.152 fefe 678: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 679: Fix fseek return value.
1.155 fefe 680: Add dirname and basename.
1.156 fefe 681: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 682: Fixed getservent (did not allow _ and - in the aliases).
683: Thanks, Oden Eriksson
1.158 fefe 684: Added a float.h so configure believes we have ANSI header files.
685: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 686: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 687: scanf and printf function implementations
1.160 fefe 688: Imported a few more functions and optimizations from Frank Klemm (he
689: also rewrote dtostr to have more precision)
1.161 olaf 690: Olaf: checked in a new sig* function family (based on rt_sig*).
691: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 692: Made rudimentary iconv that can convert back and forth between
693: iso-8859-1, utf-8 and ucs-4 (for debugging).
694: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 695:
1.74 fefe 696: 0.10:
697: update getpagesize.
698: add personality.
1.75 fefe 699: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 700: add putchar (apparently arm-linux-gcc will substitute printf("\n")
701: with putchar('\n') behind your back...?!
1.77 fefe 702: import include/scsi/ from glibc.
1.78 fefe 703: add iopl.
1.80 fefe 704: add execl and sigdelset prototypes.
705: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 706: add RPC headers (no code yet).
1.82 fefe 707: add mlockall, munlockall
1.83 fefe 708: make "diet gcc foo.c" work.
709: added Sun RPC code and removed as many warnings as possible in a
710: heroic act of self-mutilation.
711: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 712: added getpass. mount from util-linux actually compiles now!
713: fix the sig*set routines. mount actually works now *bg*
714: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 715: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 716: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 717: add res_init.
718: add asprintf (ugh, what an ugly function).
1.89 fefe 719: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 720: add ut_name alias to ut_host in struct utmp.
721: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 722: add sysinfo, recvmsg, sendmsg.
1.93 fefe 723: add endmntent, getmntent, setmntent.
1.94 fefe 724: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 725: add setenv.
726: remove __restrict from mntent.h, add __restrict__ removal alias for
727: older gcc versions in sys/cdefs.h.
728: add rlim_t, sig_atomic_t declarations.
729: add sigsetjmp #define for __sigsetjmp (oops).
730: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 731: add a gruesome hack to printf floating point to accept %f and kludge
732: together support for %.2f. Don't look at the code, please!
1.98 fefe 733: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 734: imported fix for entlib by Jeff Garzik.
1.100 fefe 735: add glob implementation from Guillaume Cottenceau (Thanks!!)
736: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 737: add REG_ICASE and word start/end handling to my regular expressions.
738: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 739: wrap getcwd to comply to man page (the syscall returns the number of
740: bytes, not the buffer)
741: add realpath.
1.103 fefe 742: fix vfprintf.
1.104 fefe 743: fix *scanf %s zero termination.
744: add abs, labs, llabs.
1.105 fefe 745: add <sys/io.h>, ioperm syscall.
746: add flock to <sys/file.h>
1.106 fefe 747: fixes to bsearch and the regular expressions.
1.107 fefe 748: add fake herror.
1.108 fefe 749: add scandir and alphasort.
1.109 fefe 750: add killpg
1.110 fefe 751: implemented a gross hack to make libpthread compile when
752: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 753: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 754: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 755: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
756: for sending a patch.
1.114 fefe 757: add getserv*.
758: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
759: "search" from resolv.conf.
1.74 fefe 760:
1.73 fefe 761: 0.9:
1.65 fefe 762: fixed initgroups (oops)
1.66 fefe 763: Cleanup appending file open for stdio (thanks, James Antill)
764: imported vfprintf fix from James Antill.
1.67 fefe 765: add fnmatch
766: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 767: Olaf added character classes to *scanf.
1.69 fefe 768: Put object and library files into a separate directory (bin-$ARCH).
769: Add "cross" make target to make all architectures.
770: Add "diet" program and man page.
1.70 fefe 771: Add getgrnam, getgrgid
1.71 fefe 772: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 773: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 774:
1.64 fefe 775: 0.8:
1.34 fefe 776: vsnprintf(0,...) estimated the length of strings with a padding width
777: incorrectly.
1.35 fefe 778: new reboot() from Olaf.
1.36 fefe 779: added prototypes for getsockopt and setsockopt.
1.39 fefe 780: added experimental sem* and shm*
1.38 fefe 781: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 782: added setvbuf (only changes mode, not buffer)
1.41 fefe 783: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
784: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 785: added qsort() and bsearch(). Benchmark on 1000 random ints:
786: glibc: 679414 cycles qsort and 3352 cycles bsearch
787: diet libc: 300010 cycles qsort, 553 cycles bsearch
788: I have no idea why glibc is so slow.
1.43 fefe 789: added __isnan (references by libm.a from glibc).
790: added popen() and pclose(). Now the diet libc can link slsh (from
791: S-Lang!)
1.44 fefe 792: corrected usleep. It was more of an msleep until now.
1.45 fefe 793: corrected __dtostr (it looped when trying to format "0.0").
794: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 795: added ungetc (does it work?)
1.47 fefe 796: added inet_aton (yuck!)
1.50 fefe 797: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 798: added h_errno and __h_errno_location
799: added inet_ntoa
1.49 fefe 800: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 801: add bcopy, index, rindex macros
802: add isgraph and isxdigit
1.52 fefe 803: add strftime (ugh!!!)
1.53 olaf 804: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 805: Jeff Garzik contributed a spec file. I put it in contrib and hope
806: everbody knows what to do with it...
807: Olaf checked in a ton of libpthread stuff.
1.55 fefe 808: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 809: add large file backwards compatibility support (so gzip will run on
810: kernel 2.2 and 2.0)
1.57 fefe 811: added shutdown
1.58 fefe 812: added nice
813: added pseudo-locale support for is* (they are now weak aliases,
814: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
815: overwrite the default is* functions.
1.59 fefe 816: added liblatin1.a
1.60 fefe 817: added tzfile implementation (does it work for anyone else?)
1.61 fefe 818: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 819: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
820: Thanks!
1.63 fefe 821: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 822:
1.21 fefe 823: 0.7.2:
824: added several prototypes to already implemented functions and
825: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 826: added prototypes for process group and dup syscalls. Thanks to
827: Abraham again. He also contributed an implementation for daemon(),
828: an ugly BSD hack. I decided to diversify the lib/ directory a
829: little and now created a libugly/ directory for stuff like system()
830: and daemon() ;-)
831: added libstdio and moved all that stdio crap from lib/ there. The
832: idea is to start separating now what we will separate for shared
833: libraries anyway.
1.26 fefe 834: optimized x86 unified-syscall by Olaf.
1.27 fefe 835: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
836: limits.h instead)
837: added remove.c and enough cruft to limits.h to make it compile lzo,
838: lzop and bzip2.
1.28 fefe 839: added mktime, asctime_r, asctime and ctime (needed for gzip).
840: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 841: format some day (man tzfile, ugh!) :-(
1.29 fefe 842: added unlink prototype to unistd.h.
843: added gmtime and gmtime_r.
1.31 fefe 844: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 845: removed readdir glibc compatibility cruft.
1.31 fefe 846: removed stat glibc compatibility cruft.
1.32 fefe 847: oops, my fread was broken for pipes.
1.33 fefe 848: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 849:
1.9 fefe 850: 0.7.1:
1.11 fefe 851: optimized away the static arrays from __ltostr and __lltostr.
852: optimized away the static arrays (and more!) from strtoul and strtoull.
853: added system (by Olaf).
1.12 fefe 854: added tolower and toupper
1.13 fefe 855: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 856: added clone for mips (by Olaf).
857: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 858: added pause for all (by Olaf).
1.17 fefe 859: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 860: added isupper and islower.
861: added putc and putchar as macros.
1.17 fefe 862: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
863: insightful discussions and patches I partially used for the last three)
1.18 fefe 864: added getpriority and setpriority (also by Abraham)
1.19 fefe 865: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 866: oi, setjmp and longjmp were broken on other platforms, too!
867: Thanks to Sébastien Côté for reporting this.
1.9 fefe 868:
869: 0.7:
1.6 olaf 870: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 871: Initial dynamic loading glue for i386, also by Olaf.
872: We don't have a dynamic loader yet, so this is not yet usable.
873: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
874: vsprintf, writev, all by Olaf.
1.2 fefe 875: imported readdir fix from Guillaume. Mhh, can the kernel interface
876: really be this broken?
1.3 fefe 877: Found a kludgy way to detect whether the kernel includes define struct
878: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
879: not work for you, please tell me!
1.4 fefe 880: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 881: Fixed stdio line buffering. The code was already there but I forgot
882: to mark stdio and stdout as line buffered. This should really be
883: done dynamically using isatty, though.
1.8 fefe 884: Removed superfluous "if (1)" in execvp.c
1.1 cvs 885:
886: 0.6.14:
887: *scanf did not append the 0 byte for %s.
888: added creat and changed creat to call open directly instead of open64.
889: did for fread what 0.6.10 did for fwrite.
890: repaired buffered stdio a little (line buffering is still not
891: supported).
892: [All of these bugs have been reported by Guillaume. Thanks!]
893: added __pure__ to strchr and strrchr in <string.h>
894:
895: 0.6.13:
896: included COPYING to make clear that the diet libc is covered by the
897: GNU General Public License (and _not_ the LGPL). That means that
898: you need to obtain a license from me if you want to use the diet
899: libc in a proprietary program that you want to distribute.
900: The x86 unified syscall swapped arguments #4 and #5 and noone
901: noticed until now! Thanks to Guillaume Cottenceau for reporting
902: this!
903: The malloc had a subtle bug with small allocations that could cause
904: segfault. Guillaume reported it, Olaf fixed it.
905:
906: 0.6.12:
907: added assert, statfs and fstatfs
908: added include/net/if.h so fget compiles again.
909:
910: 0.6.11:
911: added putenv.
912:
913: 0.6.10:
914: fixed fwrite. It returned the number of bytes written, not the number
915: of records. Thanks to Albert D. Cahalan for pointing this out.
916: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
917: added brk and sbrk. harold@nb.com.sg made me do it.
918:
919: 0.6.9:
920: fixed execvp not to return on ENOENT
921: did for {open|read|close|seek|tell}dir what I did for stat before.
922: The glibc compatibility part is currently non-functional.
923: fixed white space handling in sscanf " (" would not match " (".
924: fixed printf to accept 'l' flag.
925: fixed getpwuid (ignored last line)
926:
927: 0.6.8:
928: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
929: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
930: added strlcpy and strlcat from OpenBSD.
931: added stat64, fstat64 and lstat64.
932: added endian.h and made ending of strlen.c endianness-aware
933: added string routines size tweak to dietfeatures.h. Most of the
934: string routines have been unrolled. This is up to three times as
935: fast but creates up to three times larger code. Now you can disable
936: the unrolling.
937: added sendfile.
938: I also added pread. It works on x86 and sparc but not on ppc and mips.
939: I have no idea what's going on. strace disagrees with the kernel.
940: Can anyone help? I asked the Linux kernel mailing list for help, too.
941: added a few aliases of the type __libc_open for open. nm on
942: libpthreads.so indicates that we will need them.
943:
944: 0.6.7:
945: the sources now compile without warnings with -Wall.
946: printf now prints "(null)" when %s is passed NULL. This can be
947: removed with WANT_NULL_PRINTF in dietfeatures.h
948: added vfprintf, execl, ttyname.
949: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
950: __dietfstat so they can use the normal kernel struct stat.
951: stat, lstat and fstat are now C wrappers that convert to the glibc
952: struct stat. So we can avoid that overhead for programs that use
953: dietlibc headers.
954:
955: 0.6.6:
956: changed the Makefiles so you can now set CFLAGS on the command line
957: added memccmp (analogous to memccpy) and strncmp.
958: Olaf fixed another bug in the sparc unified syscall.
959: Paul Clifford contributed a C version of his strlen.S that is much
960: more efficient than the previous strlen on all platforms! It also
961: looks like technology from Roswell. ;-}
962: added a "real" stdio. Well, almost. Please contribute!
963: added dietfeatures.h so you can remove features you don't need.
964: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
965: stdio now works with simple programs and minigzip from libz.
966: stdio uses some major trickery to avoid linking the stdio, stderr and
967: stdout (and reserving space for them) when they are not used.
968:
969: 0.6.5:
970: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
971: most of them bugs in the new header files, but also missing sigset
972: functions.
973: Paul Clifford contributed an assembly strlen.S for ARM and fixed
974: several bugs.
975: Fixed ppc/setjmp and mips/pipe.
976: Olaf contributed a new sparc unified syscall.
977:
978: 0.6.4:
979: declared is* static inline in getservent.
980: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
981: changed strlen to return 0 when passed NULL.
982: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
983: Scientist who actually implemented this without access to a MIPS
984: box, just from reading the architecture manual. And it worked out
985: of the box.
986: started a set of system includes, mainly so that I can use lcc and
987: my alpha-linux cross compiler (which is unable to cross-compile
988: glibc). diet libc can now be compiled without any include files
989: from a normal libc. The includes do declare more than diet libc
990: currently delivers and they are still far from complete for real
991: applications.
992: I will only add assembly versions that are smaller _and_ faster than
993: the C version. Larger routines are only accepted if they are called
994: very often and are substantially faster.
995: added i386 assembly strchr, which is smaller and faster than the old
996: version. It is, however, larger than the version contributed by
997: proton (thanks, anyway).
998: added i386 strlen (31% faster, 14% smaller)
999: "make t" will now create a map file called "mapfile".
1000:
1001: 0.6.3:
1002: added sys_errlist, strerror and perror
1003: added isblank
1004: added atol
1005:
1006: 0.6.2:
1007: mmap for ARM didn't compile. Thanks, Paul!
1008:
1009: 0.6.1:
1010: split mmap into the architecture specific subdirectories.
1011: getenv now copes with environ==NULL, thanks Paul Clifford.
1012: Paul also contributed a smaller ARM startup code.
1013:
1014: 0.6:
1015: strcat returned the wrong result. Thanks, Dietz Pröpper.
1016: strtod now understands a negative exponent (oops, thanks Bertram Barth)
1017: Port to arm-linux-gnu, but on the Netwinder I use for testing the
1018: __dtostr does not work (I have no idea why!)
1019: The MIPS port now uses (much smaller) non-PIC code. That means that
1020: the applications you link against diet libc also have to be compiled
1021: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
1022: Thanks to Ralf Bächle for helping me with this!
1023: I made subdirectories for the architectures and use VPATH to override
1024: VPATH so that make finds the source file automatically. That should
1025: simplify the sources greatly.
1026: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
1027: ARM and MIPS now also have setjmp and longjmp
1028: "compile" and "load" are now make targets. Use them for djb programs.
1029: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1030: Again, contributed from Olaf. Great work!
1031:
1032: 0.5.12:
1033: printf also does signed numbers.
1034: If you don't use atexit, dietlibc now does not link exit, only _exit.
1035: *printf now correctly returns the number of bytes written.
1036: Olaf contributed experimental sscanf and vsscanf implementations.
1037: If passed NULL as buffer, snprintf will not write anything but still
1038: return the number of bytes it would have written.
1039: Initial MIPS port! (Oh, the agony!)
1040: No setjmp and longjmp support yet! Please contribute!
1041: I even implemented unified syscalls for MIPS. Still, MIPS code is
1042: almost twice the size of SPARC code. If anyone knows why: please
1043: tell me!
1044:
1045: 0.5.11:
1046: I implemented new unified syscalls for x86, sparc and ppc, this time based
1047: on .s files and not .c files, and I moved the syscalls into
1048: subdirectores to clean the dietlibc sources up a little.
1049: A binary consisting of printf("%s is %d\n","olaf",23) is now
1050: 2864 bytes on sparc
1051: 2488 bytes on intel
1052: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1053: to make a few more applications work.
1054: Olaf Dreesen also implemented some unified syscall stuff for x86.
1055: He discovered that with our unified syscall interface it actually
1056: costs <10 bytes total to make all system calls thread safe!
1057: I implemented atexit() (can register up to 4 callbacks).
1058: I implemented strtod and __dtostr (the opposite). Now we can add
1059: floating point support to vsnprintf and sscanf!
1060:
1061: 0.5.10:
1062: I actually saw that I can not only merge the errno handling code of
1063: the system calls on x86, I can also merge the rest (including the
1064: arguments) except for setting the system call number. All those
1065: system calls are now just a jump to a unified system call handler.
1066: I got rid of x86openclose again. The savings are substantial:
1067: chown from embutils went from 7664 to 7184 bytes!
1068: If I'd move the system call wrappers to assembly language, I could
1069: even reduce the alignment (does not matter since it's just a jump
1070: anyway) and get rid of the "ret" behind each jump (one byte per
1071: system call!)
1072:
1073: 0.5.9:
1074: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1075: fixed strdup
1076: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1077: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1078: (no signed integers, only strings and unsigned integers (but
1079: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1080: that code must be wonderful, I don't understand it at all *bg*)
1081: Olaf's printf does understand padding like in "%08d" and "%8d" and
1082: automatically pads pointers with '0'.
1083: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1084: Thanks to proton for inspiration on this.
1085: The new x86 start code also does not reference exit any more, thus saving
1086: 64 bytes for executables that don't call exit explicitly.
1087: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1088: Moved errno and environ to start.S, saving no byte binary size but
1089: speeding up compilation and slightly shortening dietlibc.a ;-)
1090: For x86: joined open and close into one assembler file, sharing the
1091: errno handling. This is a feasibility test and it actually saves a
1092: few bytes. I think I will reimplement the _syscall[1-6] macros on
1093: all platforms now to share the errno handling code for them.
1094:
1095: 0.5.8:
1096: fixed strchr to be able to look for 0.
1097:
1098: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1099: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1100: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1101: contributed by Olaf Dreesen)
1102:
1103: added execvp, getcwd
1104:
1105: fixed __xmknod
1106:
1107: Note: can it be that the ftw interface really is so broken that I
1108: cannot implement it without having to implement some searching data
1109: structure? I included an experimental ftw implementation that will
1110: not follow symlinks.
1111:
1112: 0.5.7:
1113: oops, if_nametoindex was broken!
1114:
1115: 0.5.6:
1116: ported to ppc-linux.
1117: fixed i386 sigsetjmp (I mistyped the function name)
1118: included sigjmp.c
1119:
1120: 0.5.5:
1121: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1122: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1123: I fixed it now.
1124: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1125: fixed readdir to use getdents and not the intel inline asm
1126:
1127: 0.5.4:
1128: ported to sparclinux (sparc32 only). Beware: does not work yet.
1129: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1130:
1131: 0.5.3:
1132: added tcsetattr and getenv to compile e3
1133:
1134: 0.5.2:
1135: added vhangup, tcgetattr, isatty and memcmp for fgetty
1136: (http://www.fefe.de/fgetty/)
1137: added localtime from uC-libc.
1138:
1139: 0.5.1:
1140: stat and friends actually work now. Yuck! Another case of
1141: translation between kernel and userland. Why can't the kernel
1142: people and the libc people simply agree on a standard?
1143: removed many unnecessary includes to speed up compilation.
1144: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1145: inlined socketcall to reduce code size.
1146: "load" and "compile" are examples for djb code.
1147:
1148: 0.5:
1149: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1150: each object file is now treated with "strip -x -R .note -R .comment"
1151: split each system call into a separate object file
1152: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1153:
1154: 0.4.1:
1155: oops, the strchr implementation was wrong. Thanks Jens Laas!
1156:
1157: 0.4:
1158: copied opendir and friends from uC-libc.
1159: added getservent and getservby* in gerservent.c
1160:
1161: 0.3:
1162: remove readdir system call
1163: added getdents system call
1164: added getpwnam/getpwuid implementation in getpwnam.c
1165: added a few string functions (in str*.c)
