350: adjusted lstat->lstat64 #define to make it work with function pointers
351: move __dietlibc__ #define from features.h to diet
1.267 fefe 352: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
353: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 354: Thomas also sent me profiling support (so far only on x86, but
355: profiling/PORTING describes what needs to be done for other
356: architectures)!
1.272 fefe 357: add contrib/dprof.c, also from Thomas.
1.269 fefe 358: Andreas Krennmair sent a patch to add the BSD regex interface to
359: libcompat
1.271 fefe 360: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 361: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 362: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 363: abort did not flush all stdio streams
1.277 fefe 364: fix some nasty regular expression bugs
365: write a stupid malloc checker (contrib/debug-realloc.c) to help me
366: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 367: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 368: fix DNS domain search
1.280 fefe 369: i386 memccpy exchanged esi and edi :-( I should do more checks before
370: accepting external code...
1.264 fefe 371:
1.244 fefe 372: 0.16:
373: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 374: Andre found two very embarassing bugs in my four lines of md5 glue.
375: I need to get more sleep.
1.247 fefe 376: Thanks Ogrisegg found that ptrace does not work as documented and
377: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 378: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
379: fix ptrace.h for S/390 and ARM
380: provide a PORTING document so we don't lose track of which file need
381: to be touched to port the diet libc to a new platform.
1.249 fefe 382: remove a few warnings
383: provide a prototype for usleep.
1.250 fefe 384: make __dtostr work on ARM by using long instead of long long.
385: Idea by Dirk Engling.
1.251 fefe 386: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 387: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 388: Kurt Garloff sent in patches to
389: fix struct termios on non-x86 architectures
1.254 fefe 390: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
391: create libcompat.a (and move daemon to it)
1.255 fefe 392: add getdelim and getline
393: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 394: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 395: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 396: Hans Lermen fixed i386/getenv.S
1.259 fefe 397: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 398: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
399: Macodiseas)
1.261 fefe 400: sys/ipc.h now includes sys/types.h
1.262 olaf 401: Olaf: started to make the sparc64 port
1.263 fefe 402: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 403:
1.224 fefe 404: 0.15:
1.225 fefe 405: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 406: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 407: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
408: thread-safe!
1.228 fefe 409: remove vfork and add alarm to dynamic syscalls.
410: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 411: The MD5 code generated unaligned accesses when passed an unaligned
412: pointer on little endian ARM and MIPS.
413: MIPS unified syscall didn't compile anymore.
414: Put up new mipsel target to cross compile for little endian mips.
415: The mips target will again explicitly set endianness to big endian.
416: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 417: Duh, when we removed return0, we broke tzset when the time zone parser
418: was disabled. Uwe Ohse noticed this. Thanks!
419: Fix gethostbyname to match host names case insensitively in /etc/hosts.
420: Oops, this was reported 6 weeks ago but I overlooked the email.
421: Thanks, Denis Rachal!
1.231 fefe 422: vsnprintf's zero termination was broken.
1.233 fefe 423: Uwe Ohse found a few more bugs:
424: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
425: does it correctly.
426: Make inet_aton use strtoul instead of strtol
427: fdopen would close the file descriptor if it could not malloc the
428: buffer.
429: strftime updates.
430: Make _FILE_OFFSET_BITS includes -Wundef clean
431: Andre found a typo in endian.h for big endian mips
1.234 fefe 432: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 433: strstr(whatever,"") returned NULL, not whatever. Found by a new test
434: suite entry for strstr that I wrote.
1.245 fefe 435: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 436: add <asm/sigcontext.h> for profiling support.
437: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 438: an i386 assembler getenv implementation (roughly half the size)
439: add grantpt, ptsname, unlockpt
1.236 fefe 440: add a getenv test suite entry.
1.238 fefe 441: Andre contributed an ARM assembler md5 implementation and he fixed mmap
442: on ARM.
443: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 444: getservent_r did not parse lines without aliases. Thanks, Jaroslav
445: Macodiseas!
1.240 fefe 446: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 447: removed annoying -Wconversion gcc switch
1.242 fefe 448: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 449: Kurt Garloff sent these diffs:
450: add fdatasync (and make it a pthread cancellation point)
451: numerous alpha issues, like using .quad instead of .long for
452: offsets, change strip to -strip in Makefile (so a failing strip does
453: not abort the make), try to be more friendly to the gcc 2.96 that
454: SuSE 7.1 AXP ships with.
1.224 fefe 455:
1.209 fefe 456: 0.14:
1.224 fefe 457: fix brk again (missing __brk, trivial oversight)
1.210 fefe 458: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
459: Thomas Ogrisegg!
1.211 fefe 460: Thomas also contributed a PA-RISC port including testandset, so
461: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 462: made the fake locale more believable.
463: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 464: moved _exit into the unified syscall on x86.
1.214 fefe 465: Uwe Ohse found many more bugs:
466: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
467: liblatin1 was more or less completely broken if you gave it chars as
468: arguments, not ints (signedness). execvp had a buffer overflow in
469: case a PATH element exceeded PATH_MAX, but it's not a security
470: problem since setuid programs need to set their path to some known
471: value anyway.
1.219 fefe 472: hasmntopt did not work with foo=bar style options
1.217 fefe 473: Uwe also improved ftw's stack usage.
1.214 fefe 474: Put movl instead of popl rationale in comment in i386/unified.S since
475: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 476: I discovered __attribute__((malloc)) and started using it. For gcc 3,
477: it improves the optimizer when functions return malloced pointers.
1.216 fefe 478: Steven Rostedt pointed out that my setvbuf was broken with regard to
479: size==0 and sent a patch to fix it.
1.218 fefe 480: Thomas Ogrisegg made setenv smaller.
1.220 olaf 481: Olaf: implemented the parisc clone and an atomic testandset, modified the
482: libpthread to respect the parisc UPgrowing stack. still non functional,
483: because the unified syscall uses errno :(
1.221 fefe 484: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 485: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
486: don't write anything which was no longer the case. It also
487: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 488: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 489:
1.193 fefe 490: 0.13:
1.194 fefe 491: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 492: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 493: Olaf: port to S/390!
1.463 leitner 494: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 495: res_query did not initialize last
1.199 fefe 496: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 497: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 498: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 499: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 500: rewrote __dtostr (it also has one more argument now)
1.205 fefe 501: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 502: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
503: fix strncat for the case where n == 0 (security implications?)
504: fix bsearch (it didn't find the very last element in the array, same
505: bug in both the C and the i386 assembly version).
1.205 fefe 506: fixed FNM_PATHNAME in fnmatch
1.204 fefe 507: fix brk (the syscall was documented incorrectly in the Linux man page)
508: Thanks, Thomas Ogrisegg!
1.205 fefe 509: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 510: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 511: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 512:
1.164 fefe 513: 0.12:
514: more contributions from Frank Klemm.
1.165 fefe 515: iconv can now do UCS-2, too.
1.167 fefe 516: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 517: Lots of bug fixes, and several more i386 specific versions of common
518: routines to make them smaller.
1.168 fefe 519: add memmem (a GNU extension that looks useful)
1.170 fefe 520: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 521: add pivot_root syscall, %n for *scanf.
1.169 fefe 522: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 523: add Frank Klemm's optimized md5
1.172 fefe 524: add -Os option to diet (see diet.1).
1.173 fefe 525: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 526: add 32-bit uid/gid syscalls.
1.175 fefe 527: add rand48 (thanks, Johannes Kloos)
1.176 fefe 528: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 529: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
530: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
531: fix gethostent alias list termination. Major oops.
1.178 fefe 532: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 533: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 534: DNS will now properly signal errors and set h_errno.
535: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 536: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
537: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
538: external reference to a symbol that is only in the diet libc. So,
539: when you accidentally link a diet libc compiled object file against
540: glibc, the linker will barf. This will bloat your object files, but
541: you can remove all the references with "strip -R .note" from
542: the binaries in the end (which you should do anyway).
1.182 fefe 543: fix ARM unified syscall (select did not work).
1.183 fefe 544: add getpwent_r ala glibc and replace getpwent
545: do the same for getgrent and getspent
546: remove entlib (new code is smaller)
1.184 fefe 547: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 548: add getpwnam_r and getpwuid_r
1.186 fefe 549: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 550: Olaf muddled with the dynamic linker. It's a clean-room
551: implementation in the sense that it once worked for Olaf in a clean
552: room ;)
1.188 fefe 553: add if_nameindex and if_freenameindex.
554: fixed arm unified syscalls to work with current binutils (; is no
555: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 556: changed all st_[cma]time types to signed long so comparisons against
557: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 558: fixed two bugs regarding ungetc.
559: add getusershell, setusershell, endusershell (for vs_ftpd)
560: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 561: fixed strftime (was completely hosed)
1.192 fefe 562: added real make install target
1.164 fefe 563:
1.115 fefe 564: 0.11:
565: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 566: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 567: add floor, ceil and memchr prototypes.
568: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 569: cleaner errno vs __errno_location handling
570: add placeholder iconv (iconv_open will always return EINVAL)
571: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
572: initialization of getaddrinfo.
1.119 fefe 573: fix vsnprintf %X (printed lower case)
1.120 fefe 574: I wrote a new getopt. It appears to actually work (it is POSIX
575: compliant, it does not sort argv like the GNU version) and is only
576: a little over 300 bytes on x86.
1.121 fefe 577: Guillaume Cottenceau just wrote me that strncat should be even more
578: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 579: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 580: Fix regexec offset return. autoconf now believes that diet libc has
581: POSIX regular expressions.
1.123 fefe 582: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 583: Fix regular expression match for x* when there is no x at all.
1.125 fefe 584: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 585: Add %h to vsnprintf.
1.127 fefe 586: Add FAQ.
1.128 fefe 587: Make %h work for signed numbers and add %hh to vsnprintf.
588: initgroups ignored the group argument :-(
589: remove printf references and nested functions from glob.
1.129 fefe 590: added an errno in libpthread that will display a prominent linker
591: warning.
1.131 fefe 592: started getting rid of kernel headers. Big task! :-(
1.130 fefe 593: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 594: Olaf: added a lot of code in libdl (not yet complete), changed the
595: startup code to make it work with his libdl and ld.so (needs still work
596: too)
1.134 fefe 597: __dns_readstartfiles only took the first domain or search path.
598: Thanks, Anthony de Boer
1.133 olaf 599: Olaf: added clone and a new unified_syscall for PowerPC
600: also dynlinker is now available (i386 only at this time)
1.135 fefe 601: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 602: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 603: fixed word delimiters in regex (they looked for space, i.e. "," did
604: not work as delimiter)
1.138 fefe 605: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 606: added mkdtemp.
1.142 fefe 607: Uwe Ohse reported all of the following bugs:
608: ttyname should return 0 if !isatty.
609: realpath returns NULL if "." cannot be opened
610: putenv erroneously accepted (and mishandled) entries without "=".
611: popen returned 255 instead of 127 if /bin/sh could not be run.
612: fgetc did not set the internal EOF indicator on EOF.
613: bsearch contained an assumption about integer arithmetic overflow
614: behavior.
615: system did not set SIGCHLD and thus contained a race.
616: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 617: daemon did not check whether open returns an fd below 3
618: perror did not save errno.
1.144 olaf 619: Olaf: Peter Jones reported some problems with perror; strerror had the
620: same problem.
621: Peter also posted a patch to atexit/exit. With some modifications it is
622: now implemented.
1.145 fefe 623: Unbuffered stdio and ungetc can no longer be disabled. I will try to
624: implement part of it using ELF weak symbols.
1.146 fefe 625: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 626: Added overflow handling for strtoul and strtol.
1.149 fefe 627: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
628: it before falling back to DNS if enabled.
1.150 fefe 629: Added a littie backwards compatibility cruft for gpm (man, do these
630: sources stink!)
1.151 fefe 631: Added openpty.
1.152 fefe 632: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 633: Fix fseek return value.
1.155 fefe 634: Add dirname and basename.
1.156 fefe 635: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 636: Fixed getservent (did not allow _ and - in the aliases).
637: Thanks, Oden Eriksson
1.158 fefe 638: Added a float.h so configure believes we have ANSI header files.
639: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 640: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 641: scanf and printf function implementations
1.160 fefe 642: Imported a few more functions and optimizations from Frank Klemm (he
643: also rewrote dtostr to have more precision)
1.161 olaf 644: Olaf: checked in a new sig* function family (based on rt_sig*).
645: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 646: Made rudimentary iconv that can convert back and forth between
647: iso-8859-1, utf-8 and ucs-4 (for debugging).
648: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 649:
1.74 fefe 650: 0.10:
651: update getpagesize.
652: add personality.
1.75 fefe 653: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 654: add putchar (apparently arm-linux-gcc will substitute printf("\n")
655: with putchar('\n') behind your back...?!
1.77 fefe 656: import include/scsi/ from glibc.
1.78 fefe 657: add iopl.
1.80 fefe 658: add execl and sigdelset prototypes.
659: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 660: add RPC headers (no code yet).
1.82 fefe 661: add mlockall, munlockall
1.83 fefe 662: make "diet gcc foo.c" work.
663: added Sun RPC code and removed as many warnings as possible in a
664: heroic act of self-mutilation.
665: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 666: added getpass. mount from util-linux actually compiles now!
667: fix the sig*set routines. mount actually works now *bg*
668: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 669: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 670: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 671: add res_init.
672: add asprintf (ugh, what an ugly function).
1.89 fefe 673: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 674: add ut_name alias to ut_host in struct utmp.
675: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 676: add sysinfo, recvmsg, sendmsg.
1.93 fefe 677: add endmntent, getmntent, setmntent.
1.94 fefe 678: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 679: add setenv.
680: remove __restrict from mntent.h, add __restrict__ removal alias for
681: older gcc versions in sys/cdefs.h.
682: add rlim_t, sig_atomic_t declarations.
683: add sigsetjmp #define for __sigsetjmp (oops).
684: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 685: add a gruesome hack to printf floating point to accept %f and kludge
686: together support for %.2f. Don't look at the code, please!
1.98 fefe 687: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 688: imported fix for entlib by Jeff Garzik.
1.100 fefe 689: add glob implementation from Guillaume Cottenceau (Thanks!!)
690: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 691: add REG_ICASE and word start/end handling to my regular expressions.
692: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 693: wrap getcwd to comply to man page (the syscall returns the number of
694: bytes, not the buffer)
695: add realpath.
1.103 fefe 696: fix vfprintf.
1.104 fefe 697: fix *scanf %s zero termination.
698: add abs, labs, llabs.
1.105 fefe 699: add <sys/io.h>, ioperm syscall.
700: add flock to <sys/file.h>
1.106 fefe 701: fixes to bsearch and the regular expressions.
1.107 fefe 702: add fake herror.
1.108 fefe 703: add scandir and alphasort.
1.109 fefe 704: add killpg
1.110 fefe 705: implemented a gross hack to make libpthread compile when
706: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 707: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 708: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 709: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
710: for sending a patch.
1.114 fefe 711: add getserv*.
712: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
713: "search" from resolv.conf.
1.74 fefe 714:
1.73 fefe 715: 0.9:
1.65 fefe 716: fixed initgroups (oops)
1.66 fefe 717: Cleanup appending file open for stdio (thanks, James Antill)
718: imported vfprintf fix from James Antill.
1.67 fefe 719: add fnmatch
720: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 721: Olaf added character classes to *scanf.
1.69 fefe 722: Put object and library files into a separate directory (bin-$ARCH).
723: Add "cross" make target to make all architectures.
724: Add "diet" program and man page.
1.70 fefe 725: Add getgrnam, getgrgid
1.71 fefe 726: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 727: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 728:
1.64 fefe 729: 0.8:
1.34 fefe 730: vsnprintf(0,...) estimated the length of strings with a padding width
731: incorrectly.
1.35 fefe 732: new reboot() from Olaf.
1.36 fefe 733: added prototypes for getsockopt and setsockopt.
1.39 fefe 734: added experimental sem* and shm*
1.38 fefe 735: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 736: added setvbuf (only changes mode, not buffer)
1.41 fefe 737: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
738: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 739: added qsort() and bsearch(). Benchmark on 1000 random ints:
740: glibc: 679414 cycles qsort and 3352 cycles bsearch
741: diet libc: 300010 cycles qsort, 553 cycles bsearch
742: I have no idea why glibc is so slow.
1.43 fefe 743: added __isnan (references by libm.a from glibc).
744: added popen() and pclose(). Now the diet libc can link slsh (from
745: S-Lang!)
1.44 fefe 746: corrected usleep. It was more of an msleep until now.
1.45 fefe 747: corrected __dtostr (it looped when trying to format "0.0").
748: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 749: added ungetc (does it work?)
1.47 fefe 750: added inet_aton (yuck!)
1.50 fefe 751: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 752: added h_errno and __h_errno_location
753: added inet_ntoa
1.49 fefe 754: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 755: add bcopy, index, rindex macros
756: add isgraph and isxdigit
1.52 fefe 757: add strftime (ugh!!!)
1.53 olaf 758: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 759: Jeff Garzik contributed a spec file. I put it in contrib and hope
760: everbody knows what to do with it...
761: Olaf checked in a ton of libpthread stuff.
1.55 fefe 762: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 763: add large file backwards compatibility support (so gzip will run on
764: kernel 2.2 and 2.0)
1.57 fefe 765: added shutdown
1.58 fefe 766: added nice
767: added pseudo-locale support for is* (they are now weak aliases,
768: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
769: overwrite the default is* functions.
1.59 fefe 770: added liblatin1.a
1.60 fefe 771: added tzfile implementation (does it work for anyone else?)
1.61 fefe 772: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 773: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
774: Thanks!
1.63 fefe 775: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 776:
1.21 fefe 777: 0.7.2:
778: added several prototypes to already implemented functions and
779: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 780: added prototypes for process group and dup syscalls. Thanks to
781: Abraham again. He also contributed an implementation for daemon(),
782: an ugly BSD hack. I decided to diversify the lib/ directory a
783: little and now created a libugly/ directory for stuff like system()
784: and daemon() ;-)
785: added libstdio and moved all that stdio crap from lib/ there. The
786: idea is to start separating now what we will separate for shared
787: libraries anyway.
1.26 fefe 788: optimized x86 unified-syscall by Olaf.
1.27 fefe 789: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
790: limits.h instead)
791: added remove.c and enough cruft to limits.h to make it compile lzo,
792: lzop and bzip2.
1.28 fefe 793: added mktime, asctime_r, asctime and ctime (needed for gzip).
794: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 795: format some day (man tzfile, ugh!) :-(
1.29 fefe 796: added unlink prototype to unistd.h.
797: added gmtime and gmtime_r.
1.31 fefe 798: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 799: removed readdir glibc compatibility cruft.
1.31 fefe 800: removed stat glibc compatibility cruft.
1.32 fefe 801: oops, my fread was broken for pipes.
1.33 fefe 802: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 803:
1.9 fefe 804: 0.7.1:
1.11 fefe 805: optimized away the static arrays from __ltostr and __lltostr.
806: optimized away the static arrays (and more!) from strtoul and strtoull.
807: added system (by Olaf).
1.12 fefe 808: added tolower and toupper
1.13 fefe 809: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 810: added clone for mips (by Olaf).
811: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 812: added pause for all (by Olaf).
1.17 fefe 813: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 814: added isupper and islower.
815: added putc and putchar as macros.
1.17 fefe 816: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
817: insightful discussions and patches I partially used for the last three)
1.18 fefe 818: added getpriority and setpriority (also by Abraham)
1.19 fefe 819: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 820: oi, setjmp and longjmp were broken on other platforms, too!
821: Thanks to Sébastien Côté for reporting this.
1.9 fefe 822:
823: 0.7:
1.6 olaf 824: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 825: Initial dynamic loading glue for i386, also by Olaf.
826: We don't have a dynamic loader yet, so this is not yet usable.
827: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
828: vsprintf, writev, all by Olaf.
1.2 fefe 829: imported readdir fix from Guillaume. Mhh, can the kernel interface
830: really be this broken?
1.3 fefe 831: Found a kludgy way to detect whether the kernel includes define struct
832: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
833: not work for you, please tell me!
1.4 fefe 834: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 835: Fixed stdio line buffering. The code was already there but I forgot
836: to mark stdio and stdout as line buffered. This should really be
837: done dynamically using isatty, though.
1.8 fefe 838: Removed superfluous "if (1)" in execvp.c
1.1 cvs 839:
840: 0.6.14:
841: *scanf did not append the 0 byte for %s.
842: added creat and changed creat to call open directly instead of open64.
843: did for fread what 0.6.10 did for fwrite.
844: repaired buffered stdio a little (line buffering is still not
845: supported).
846: [All of these bugs have been reported by Guillaume. Thanks!]
847: added __pure__ to strchr and strrchr in <string.h>
848:
849: 0.6.13:
850: included COPYING to make clear that the diet libc is covered by the
851: GNU General Public License (and _not_ the LGPL). That means that
852: you need to obtain a license from me if you want to use the diet
853: libc in a proprietary program that you want to distribute.
854: The x86 unified syscall swapped arguments #4 and #5 and noone
855: noticed until now! Thanks to Guillaume Cottenceau for reporting
856: this!
857: The malloc had a subtle bug with small allocations that could cause
858: segfault. Guillaume reported it, Olaf fixed it.
859:
860: 0.6.12:
861: added assert, statfs and fstatfs
862: added include/net/if.h so fget compiles again.
863:
864: 0.6.11:
865: added putenv.
866:
867: 0.6.10:
868: fixed fwrite. It returned the number of bytes written, not the number
869: of records. Thanks to Albert D. Cahalan for pointing this out.
870: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
871: added brk and sbrk. harold@nb.com.sg made me do it.
872:
873: 0.6.9:
874: fixed execvp not to return on ENOENT
875: did for {open|read|close|seek|tell}dir what I did for stat before.
876: The glibc compatibility part is currently non-functional.
877: fixed white space handling in sscanf " (" would not match " (".
878: fixed printf to accept 'l' flag.
879: fixed getpwuid (ignored last line)
880:
881: 0.6.8:
882: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
883: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
884: added strlcpy and strlcat from OpenBSD.
885: added stat64, fstat64 and lstat64.
886: added endian.h and made ending of strlen.c endianness-aware
887: added string routines size tweak to dietfeatures.h. Most of the
888: string routines have been unrolled. This is up to three times as
889: fast but creates up to three times larger code. Now you can disable
890: the unrolling.
891: added sendfile.
892: I also added pread. It works on x86 and sparc but not on ppc and mips.
893: I have no idea what's going on. strace disagrees with the kernel.
894: Can anyone help? I asked the Linux kernel mailing list for help, too.
895: added a few aliases of the type __libc_open for open. nm on
896: libpthreads.so indicates that we will need them.
897:
898: 0.6.7:
899: the sources now compile without warnings with -Wall.
900: printf now prints "(null)" when %s is passed NULL. This can be
901: removed with WANT_NULL_PRINTF in dietfeatures.h
902: added vfprintf, execl, ttyname.
903: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
904: __dietfstat so they can use the normal kernel struct stat.
905: stat, lstat and fstat are now C wrappers that convert to the glibc
906: struct stat. So we can avoid that overhead for programs that use
907: dietlibc headers.
908:
909: 0.6.6:
910: changed the Makefiles so you can now set CFLAGS on the command line
911: added memccmp (analogous to memccpy) and strncmp.
912: Olaf fixed another bug in the sparc unified syscall.
913: Paul Clifford contributed a C version of his strlen.S that is much
914: more efficient than the previous strlen on all platforms! It also
915: looks like technology from Roswell. ;-}
916: added a "real" stdio. Well, almost. Please contribute!
917: added dietfeatures.h so you can remove features you don't need.
918: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
919: stdio now works with simple programs and minigzip from libz.
920: stdio uses some major trickery to avoid linking the stdio, stderr and
921: stdout (and reserving space for them) when they are not used.
922:
923: 0.6.5:
924: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
925: most of them bugs in the new header files, but also missing sigset
926: functions.
927: Paul Clifford contributed an assembly strlen.S for ARM and fixed
928: several bugs.
929: Fixed ppc/setjmp and mips/pipe.
930: Olaf contributed a new sparc unified syscall.
931:
932: 0.6.4:
933: declared is* static inline in getservent.
934: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
935: changed strlen to return 0 when passed NULL.
936: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
937: Scientist who actually implemented this without access to a MIPS
938: box, just from reading the architecture manual. And it worked out
939: of the box.
940: started a set of system includes, mainly so that I can use lcc and
941: my alpha-linux cross compiler (which is unable to cross-compile
942: glibc). diet libc can now be compiled without any include files
943: from a normal libc. The includes do declare more than diet libc
944: currently delivers and they are still far from complete for real
945: applications.
946: I will only add assembly versions that are smaller _and_ faster than
947: the C version. Larger routines are only accepted if they are called
948: very often and are substantially faster.
949: added i386 assembly strchr, which is smaller and faster than the old
950: version. It is, however, larger than the version contributed by
951: proton (thanks, anyway).
952: added i386 strlen (31% faster, 14% smaller)
953: "make t" will now create a map file called "mapfile".
954:
955: 0.6.3:
956: added sys_errlist, strerror and perror
957: added isblank
958: added atol
959:
960: 0.6.2:
961: mmap for ARM didn't compile. Thanks, Paul!
962:
963: 0.6.1:
964: split mmap into the architecture specific subdirectories.
965: getenv now copes with environ==NULL, thanks Paul Clifford.
966: Paul also contributed a smaller ARM startup code.
967:
968: 0.6:
969: strcat returned the wrong result. Thanks, Dietz Pröpper.
970: strtod now understands a negative exponent (oops, thanks Bertram Barth)
971: Port to arm-linux-gnu, but on the Netwinder I use for testing the
972: __dtostr does not work (I have no idea why!)
973: The MIPS port now uses (much smaller) non-PIC code. That means that
974: the applications you link against diet libc also have to be compiled
975: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
976: Thanks to Ralf Bächle for helping me with this!
977: I made subdirectories for the architectures and use VPATH to override
978: VPATH so that make finds the source file automatically. That should
979: simplify the sources greatly.
980: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
981: ARM and MIPS now also have setjmp and longjmp
982: "compile" and "load" are now make targets. Use them for djb programs.
983: added contrib/elftrunc.c which will remove unnecessary ELF headers.
984: Again, contributed from Olaf. Great work!
985:
986: 0.5.12:
987: printf also does signed numbers.
988: If you don't use atexit, dietlibc now does not link exit, only _exit.
989: *printf now correctly returns the number of bytes written.
990: Olaf contributed experimental sscanf and vsscanf implementations.
991: If passed NULL as buffer, snprintf will not write anything but still
992: return the number of bytes it would have written.
993: Initial MIPS port! (Oh, the agony!)
994: No setjmp and longjmp support yet! Please contribute!
995: I even implemented unified syscalls for MIPS. Still, MIPS code is
996: almost twice the size of SPARC code. If anyone knows why: please
997: tell me!
998:
999: 0.5.11:
1000: I implemented new unified syscalls for x86, sparc and ppc, this time based
1001: on .s files and not .c files, and I moved the syscalls into
1002: subdirectores to clean the dietlibc sources up a little.
1003: A binary consisting of printf("%s is %d\n","olaf",23) is now
1004: 2864 bytes on sparc
1005: 2488 bytes on intel
1006: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1007: to make a few more applications work.
1008: Olaf Dreesen also implemented some unified syscall stuff for x86.
1009: He discovered that with our unified syscall interface it actually
1010: costs <10 bytes total to make all system calls thread safe!
1011: I implemented atexit() (can register up to 4 callbacks).
1012: I implemented strtod and __dtostr (the opposite). Now we can add
1013: floating point support to vsnprintf and sscanf!
1014:
1015: 0.5.10:
1016: I actually saw that I can not only merge the errno handling code of
1017: the system calls on x86, I can also merge the rest (including the
1018: arguments) except for setting the system call number. All those
1019: system calls are now just a jump to a unified system call handler.
1020: I got rid of x86openclose again. The savings are substantial:
1021: chown from embutils went from 7664 to 7184 bytes!
1022: If I'd move the system call wrappers to assembly language, I could
1023: even reduce the alignment (does not matter since it's just a jump
1024: anyway) and get rid of the "ret" behind each jump (one byte per
1025: system call!)
1026:
1027: 0.5.9:
1028: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1029: fixed strdup
1030: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1031: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1032: (no signed integers, only strings and unsigned integers (but
1033: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1034: that code must be wonderful, I don't understand it at all *bg*)
1035: Olaf's printf does understand padding like in "%08d" and "%8d" and
1036: automatically pads pointers with '0'.
1037: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1038: Thanks to proton for inspiration on this.
1039: The new x86 start code also does not reference exit any more, thus saving
1040: 64 bytes for executables that don't call exit explicitly.
1041: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1042: Moved errno and environ to start.S, saving no byte binary size but
1043: speeding up compilation and slightly shortening dietlibc.a ;-)
1044: For x86: joined open and close into one assembler file, sharing the
1045: errno handling. This is a feasibility test and it actually saves a
1046: few bytes. I think I will reimplement the _syscall[1-6] macros on
1047: all platforms now to share the errno handling code for them.
1048:
1049: 0.5.8:
1050: fixed strchr to be able to look for 0.
1051:
1052: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1053: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1054: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1055: contributed by Olaf Dreesen)
1056:
1057: added execvp, getcwd
1058:
1059: fixed __xmknod
1060:
1061: Note: can it be that the ftw interface really is so broken that I
1062: cannot implement it without having to implement some searching data
1063: structure? I included an experimental ftw implementation that will
1064: not follow symlinks.

1069: 0.5.6:
1070: ported to ppc-linux.
1071: fixed i386 sigsetjmp (I mistyped the function name)
1072: included sigjmp.c
1073:
1074: 0.5.5:
1075: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1076: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1077: I fixed it now.
1078: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1079: fixed readdir to use getdents and not the intel inline asm
1080:
1081: 0.5.4:
1082: ported to sparclinux (sparc32 only). Beware: does not work yet.
1083: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access

1092:
1093: 0.5.1:
1094: stat and friends actually work now. Yuck! Another case of
1095: translation between kernel and userland. Why can't the kernel
1096: people and the libc people simply agree on a standard?
1097: removed many unnecessary includes to speed up compilation.
1098: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1099: inlined socketcall to reduce code size.
1100: "load" and "compile" are examples for djb code.
1101:
1102: 0.5:
1103: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1104: each object file is now treated with "strip -x -R .note -R .comment"
1105: split each system call into a separate object file
1106: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1107:
