1.283 fefe 323: add libm2.s from contrib to i386 (oops, how long has it been sitting
324: there?)
1.284 fefe 325: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.450 leitner 326: Michal Ludvig (SuSE) ported the diet libc to the x86_64 architecture (the
1.285 fefe 327: upcoming AMD Hammer chips!). You can't even buy the chips yet and
328: the diet libc already supports it! Amazing ;-)
329: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 330: Andre sent a patch to add ARM profiling. He says it does not work
331: yet, but it's a start.
1.287 fefe 332: added getdents64 backwards compatibility and include it in large file
333: support #defines
1.288 fefe 334: perror now checks if the message is NULL like glibc (Thomas Ogrisegg)

1.281 fefe 361:
1.264 fefe 362: 0.17:
1.265 fefe 363: fix several bugs in getservent_r
1.266 fefe 364: Gunnar Ritter reported the following:
365: moved tcgetpgrp and tcsetpgrp to unistd.h
366: adjusted lstat->lstat64 #define to make it work with function pointers
367: move __dietlibc__ #define from features.h to diet
1.267 fefe 368: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
369: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 370: Thomas also sent me profiling support (so far only on x86, but
371: profiling/PORTING describes what needs to be done for other
372: architectures)!
1.272 fefe 373: add contrib/dprof.c, also from Thomas.
1.269 fefe 374: Andreas Krennmair sent a patch to add the BSD regex interface to
375: libcompat
1.271 fefe 376: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 377: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 378: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 379: abort did not flush all stdio streams
1.277 fefe 380: fix some nasty regular expression bugs
381: write a stupid malloc checker (contrib/debug-realloc.c) to help me
382: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 383: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 384: fix DNS domain search
1.280 fefe 385: i386 memccpy exchanged esi and edi :-( I should do more checks before
386: accepting external code...
1.264 fefe 387:
1.244 fefe 388: 0.16:
389: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 390: Andre found two very embarassing bugs in my four lines of md5 glue.
391: I need to get more sleep.
1.247 fefe 392: Thanks Ogrisegg found that ptrace does not work as documented and
393: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 394: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
395: fix ptrace.h for S/390 and ARM
396: provide a PORTING document so we don't lose track of which file need
397: to be touched to port the diet libc to a new platform.
1.249 fefe 398: remove a few warnings
399: provide a prototype for usleep.
1.250 fefe 400: make __dtostr work on ARM by using long instead of long long.
401: Idea by Dirk Engling.
1.251 fefe 402: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 403: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 404: Kurt Garloff sent in patches to
405: fix struct termios on non-x86 architectures
1.254 fefe 406: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
407: create libcompat.a (and move daemon to it)
1.255 fefe 408: add getdelim and getline
409: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 410: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 411: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 412: Hans Lermen fixed i386/getenv.S
1.259 fefe 413: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 414: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
415: Macodiseas)
1.261 fefe 416: sys/ipc.h now includes sys/types.h
1.262 olaf 417: Olaf: started to make the sparc64 port
1.263 fefe 418: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 419:
1.224 fefe 420: 0.15:
1.225 fefe 421: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 422: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 423: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
424: thread-safe!
1.228 fefe 425: remove vfork and add alarm to dynamic syscalls.
426: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 427: The MD5 code generated unaligned accesses when passed an unaligned
428: pointer on little endian ARM and MIPS.
429: MIPS unified syscall didn't compile anymore.
430: Put up new mipsel target to cross compile for little endian mips.
431: The mips target will again explicitly set endianness to big endian.
432: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 433: Duh, when we removed return0, we broke tzset when the time zone parser
434: was disabled. Uwe Ohse noticed this. Thanks!
435: Fix gethostbyname to match host names case insensitively in /etc/hosts.
436: Oops, this was reported 6 weeks ago but I overlooked the email.
437: Thanks, Denis Rachal!
1.231 fefe 438: vsnprintf's zero termination was broken.
1.233 fefe 439: Uwe Ohse found a few more bugs:
440: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
441: does it correctly.
442: Make inet_aton use strtoul instead of strtol
443: fdopen would close the file descriptor if it could not malloc the
444: buffer.
445: strftime updates.
446: Make _FILE_OFFSET_BITS includes -Wundef clean
447: Andre found a typo in endian.h for big endian mips
1.234 fefe 448: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 449: strstr(whatever,"") returned NULL, not whatever. Found by a new test
450: suite entry for strstr that I wrote.
1.245 fefe 451: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 452: add <asm/sigcontext.h> for profiling support.
453: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 454: an i386 assembler getenv implementation (roughly half the size)
455: add grantpt, ptsname, unlockpt
1.236 fefe 456: add a getenv test suite entry.
1.238 fefe 457: Andre contributed an ARM assembler md5 implementation and he fixed mmap
458: on ARM.
459: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 460: getservent_r did not parse lines without aliases. Thanks, Jaroslav
461: Macodiseas!
1.240 fefe 462: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 463: removed annoying -Wconversion gcc switch
1.242 fefe 464: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 465: Kurt Garloff sent these diffs:
466: add fdatasync (and make it a pthread cancellation point)
467: numerous alpha issues, like using .quad instead of .long for
468: offsets, change strip to -strip in Makefile (so a failing strip does
469: not abort the make), try to be more friendly to the gcc 2.96 that
470: SuSE 7.1 AXP ships with.
1.224 fefe 471:
1.209 fefe 472: 0.14:
1.224 fefe 473: fix brk again (missing __brk, trivial oversight)
1.210 fefe 474: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
475: Thomas Ogrisegg!
1.211 fefe 476: Thomas also contributed a PA-RISC port including testandset, so
477: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 478: made the fake locale more believable.
479: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 480: moved _exit into the unified syscall on x86.
1.214 fefe 481: Uwe Ohse found many more bugs:
482: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
483: liblatin1 was more or less completely broken if you gave it chars as
484: arguments, not ints (signedness). execvp had a buffer overflow in
485: case a PATH element exceeded PATH_MAX, but it's not a security
486: problem since setuid programs need to set their path to some known
487: value anyway.
1.219 fefe 488: hasmntopt did not work with foo=bar style options
1.217 fefe 489: Uwe also improved ftw's stack usage.
1.214 fefe 490: Put movl instead of popl rationale in comment in i386/unified.S since
491: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 492: I discovered __attribute__((malloc)) and started using it. For gcc 3,
493: it improves the optimizer when functions return malloced pointers.
1.216 fefe 494: Steven Rostedt pointed out that my setvbuf was broken with regard to
495: size==0 and sent a patch to fix it.
1.218 fefe 496: Thomas Ogrisegg made setenv smaller.
1.220 olaf 497: Olaf: implemented the parisc clone and an atomic testandset, modified the
498: libpthread to respect the parisc UPgrowing stack. still non functional,
499: because the unified syscall uses errno :(
1.221 fefe 500: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 501: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
502: don't write anything which was no longer the case. It also
503: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 504: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 505:
1.193 fefe 506: 0.13:
1.194 fefe 507: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 508: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 509: Olaf: port to S/390!
1.463 leitner 510: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 511: res_query did not initialize last
1.199 fefe 512: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 513: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 514: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 515: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 516: rewrote __dtostr (it also has one more argument now)
1.205 fefe 517: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 518: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
519: fix strncat for the case where n == 0 (security implications?)
520: fix bsearch (it didn't find the very last element in the array, same
521: bug in both the C and the i386 assembly version).
1.205 fefe 522: fixed FNM_PATHNAME in fnmatch
1.204 fefe 523: fix brk (the syscall was documented incorrectly in the Linux man page)
524: Thanks, Thomas Ogrisegg!
1.205 fefe 525: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 526: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 527: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 528:
1.164 fefe 529: 0.12:
530: more contributions from Frank Klemm.
1.165 fefe 531: iconv can now do UCS-2, too.
1.167 fefe 532: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 533: Lots of bug fixes, and several more i386 specific versions of common
534: routines to make them smaller.
1.168 fefe 535: add memmem (a GNU extension that looks useful)
1.170 fefe 536: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 537: add pivot_root syscall, %n for *scanf.
1.169 fefe 538: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 539: add Frank Klemm's optimized md5
1.172 fefe 540: add -Os option to diet (see diet.1).
1.173 fefe 541: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 542: add 32-bit uid/gid syscalls.
1.175 fefe 543: add rand48 (thanks, Johannes Kloos)
1.176 fefe 544: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 545: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
546: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
547: fix gethostent alias list termination. Major oops.
1.178 fefe 548: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 549: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 550: DNS will now properly signal errors and set h_errno.
551: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 552: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
553: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
554: external reference to a symbol that is only in the diet libc. So,
555: when you accidentally link a diet libc compiled object file against
556: glibc, the linker will barf. This will bloat your object files, but
557: you can remove all the references with "strip -R .note" from
558: the binaries in the end (which you should do anyway).
1.182 fefe 559: fix ARM unified syscall (select did not work).
1.183 fefe 560: add getpwent_r ala glibc and replace getpwent
561: do the same for getgrent and getspent
562: remove entlib (new code is smaller)
1.184 fefe 563: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 564: add getpwnam_r and getpwuid_r
1.186 fefe 565: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 566: Olaf muddled with the dynamic linker. It's a clean-room
567: implementation in the sense that it once worked for Olaf in a clean
568: room ;)
1.188 fefe 569: add if_nameindex and if_freenameindex.
570: fixed arm unified syscalls to work with current binutils (; is no
571: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 572: changed all st_[cma]time types to signed long so comparisons against
573: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 574: fixed two bugs regarding ungetc.
575: add getusershell, setusershell, endusershell (for vs_ftpd)
576: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 577: fixed strftime (was completely hosed)
1.192 fefe 578: added real make install target
1.164 fefe 579:
1.115 fefe 580: 0.11:
581: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 582: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 583: add floor, ceil and memchr prototypes.
584: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 585: cleaner errno vs __errno_location handling
586: add placeholder iconv (iconv_open will always return EINVAL)
587: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
588: initialization of getaddrinfo.
1.119 fefe 589: fix vsnprintf %X (printed lower case)
1.120 fefe 590: I wrote a new getopt. It appears to actually work (it is POSIX
591: compliant, it does not sort argv like the GNU version) and is only
592: a little over 300 bytes on x86.
1.121 fefe 593: Guillaume Cottenceau just wrote me that strncat should be even more
594: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 595: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 596: Fix regexec offset return. autoconf now believes that diet libc has
597: POSIX regular expressions.
1.123 fefe 598: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 599: Fix regular expression match for x* when there is no x at all.
1.125 fefe 600: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 601: Add %h to vsnprintf.
1.127 fefe 602: Add FAQ.
1.128 fefe 603: Make %h work for signed numbers and add %hh to vsnprintf.
604: initgroups ignored the group argument :-(
605: remove printf references and nested functions from glob.
1.129 fefe 606: added an errno in libpthread that will display a prominent linker
607: warning.
1.131 fefe 608: started getting rid of kernel headers. Big task! :-(
1.130 fefe 609: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 610: Olaf: added a lot of code in libdl (not yet complete), changed the
611: startup code to make it work with his libdl and ld.so (needs still work
612: too)
1.134 fefe 613: __dns_readstartfiles only took the first domain or search path.
614: Thanks, Anthony de Boer
1.133 olaf 615: Olaf: added clone and a new unified_syscall for PowerPC
616: also dynlinker is now available (i386 only at this time)
1.135 fefe 617: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 618: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 619: fixed word delimiters in regex (they looked for space, i.e. "," did
620: not work as delimiter)
1.138 fefe 621: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 622: added mkdtemp.
1.142 fefe 623: Uwe Ohse reported all of the following bugs:
624: ttyname should return 0 if !isatty.
625: realpath returns NULL if "." cannot be opened
626: putenv erroneously accepted (and mishandled) entries without "=".
627: popen returned 255 instead of 127 if /bin/sh could not be run.
628: fgetc did not set the internal EOF indicator on EOF.
629: bsearch contained an assumption about integer arithmetic overflow
630: behavior.
631: system did not set SIGCHLD and thus contained a race.
632: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 633: daemon did not check whether open returns an fd below 3
634: perror did not save errno.
1.144 olaf 635: Olaf: Peter Jones reported some problems with perror; strerror had the
636: same problem.
637: Peter also posted a patch to atexit/exit. With some modifications it is
638: now implemented.
1.145 fefe 639: Unbuffered stdio and ungetc can no longer be disabled. I will try to
640: implement part of it using ELF weak symbols.
1.146 fefe 641: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 642: Added overflow handling for strtoul and strtol.
1.149 fefe 643: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
644: it before falling back to DNS if enabled.
1.150 fefe 645: Added a littie backwards compatibility cruft for gpm (man, do these
646: sources stink!)
1.151 fefe 647: Added openpty.
1.152 fefe 648: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 649: Fix fseek return value.
1.155 fefe 650: Add dirname and basename.
1.156 fefe 651: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 652: Fixed getservent (did not allow _ and - in the aliases).
653: Thanks, Oden Eriksson
1.158 fefe 654: Added a float.h so configure believes we have ANSI header files.
655: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 656: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 657: scanf and printf function implementations
1.160 fefe 658: Imported a few more functions and optimizations from Frank Klemm (he
659: also rewrote dtostr to have more precision)
1.161 olaf 660: Olaf: checked in a new sig* function family (based on rt_sig*).
661: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 662: Made rudimentary iconv that can convert back and forth between
663: iso-8859-1, utf-8 and ucs-4 (for debugging).
664: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 665:
1.74 fefe 666: 0.10:
667: update getpagesize.
668: add personality.
1.75 fefe 669: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 670: add putchar (apparently arm-linux-gcc will substitute printf("\n")
671: with putchar('\n') behind your back...?!
1.77 fefe 672: import include/scsi/ from glibc.
1.78 fefe 673: add iopl.
1.80 fefe 674: add execl and sigdelset prototypes.
675: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 676: add RPC headers (no code yet).
1.82 fefe 677: add mlockall, munlockall
1.83 fefe 678: make "diet gcc foo.c" work.
679: added Sun RPC code and removed as many warnings as possible in a
680: heroic act of self-mutilation.
681: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 682: added getpass. mount from util-linux actually compiles now!
683: fix the sig*set routines. mount actually works now *bg*
684: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 685: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 686: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 687: add res_init.
688: add asprintf (ugh, what an ugly function).
1.89 fefe 689: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 690: add ut_name alias to ut_host in struct utmp.
691: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 692: add sysinfo, recvmsg, sendmsg.
1.93 fefe 693: add endmntent, getmntent, setmntent.
1.94 fefe 694: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 695: add setenv.
696: remove __restrict from mntent.h, add __restrict__ removal alias for
697: older gcc versions in sys/cdefs.h.
698: add rlim_t, sig_atomic_t declarations.
699: add sigsetjmp #define for __sigsetjmp (oops).
700: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 701: add a gruesome hack to printf floating point to accept %f and kludge
702: together support for %.2f. Don't look at the code, please!
1.98 fefe 703: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 704: imported fix for entlib by Jeff Garzik.
1.100 fefe 705: add glob implementation from Guillaume Cottenceau (Thanks!!)
706: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 707: add REG_ICASE and word start/end handling to my regular expressions.
708: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 709: wrap getcwd to comply to man page (the syscall returns the number of
710: bytes, not the buffer)
711: add realpath.
1.103 fefe 712: fix vfprintf.
1.104 fefe 713: fix *scanf %s zero termination.
714: add abs, labs, llabs.
1.105 fefe 715: add <sys/io.h>, ioperm syscall.
716: add flock to <sys/file.h>
1.106 fefe 717: fixes to bsearch and the regular expressions.
1.107 fefe 718: add fake herror.
1.108 fefe 719: add scandir and alphasort.
1.109 fefe 720: add killpg
1.110 fefe 721: implemented a gross hack to make libpthread compile when
722: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 723: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 724: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 725: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
726: for sending a patch.
1.114 fefe 727: add getserv*.
728: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
729: "search" from resolv.conf.
1.74 fefe 730:
1.73 fefe 731: 0.9:
1.65 fefe 732: fixed initgroups (oops)
1.66 fefe 733: Cleanup appending file open for stdio (thanks, James Antill)
734: imported vfprintf fix from James Antill.
1.67 fefe 735: add fnmatch
736: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 737: Olaf added character classes to *scanf.
1.69 fefe 738: Put object and library files into a separate directory (bin-$ARCH).
739: Add "cross" make target to make all architectures.
740: Add "diet" program and man page.
1.70 fefe 741: Add getgrnam, getgrgid
1.71 fefe 742: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 743: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 744:
1.64 fefe 745: 0.8:
1.34 fefe 746: vsnprintf(0,...) estimated the length of strings with a padding width
747: incorrectly.
1.35 fefe 748: new reboot() from Olaf.
1.36 fefe 749: added prototypes for getsockopt and setsockopt.
1.39 fefe 750: added experimental sem* and shm*
1.38 fefe 751: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 752: added setvbuf (only changes mode, not buffer)
1.41 fefe 753: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
754: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 755: added qsort() and bsearch(). Benchmark on 1000 random ints:
756: glibc: 679414 cycles qsort and 3352 cycles bsearch
757: diet libc: 300010 cycles qsort, 553 cycles bsearch
758: I have no idea why glibc is so slow.
1.43 fefe 759: added __isnan (references by libm.a from glibc).
760: added popen() and pclose(). Now the diet libc can link slsh (from
761: S-Lang!)
1.44 fefe 762: corrected usleep. It was more of an msleep until now.
1.45 fefe 763: corrected __dtostr (it looped when trying to format "0.0").
764: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 765: added ungetc (does it work?)
1.47 fefe 766: added inet_aton (yuck!)
1.50 fefe 767: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 768: added h_errno and __h_errno_location
769: added inet_ntoa
1.49 fefe 770: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 771: add bcopy, index, rindex macros
772: add isgraph and isxdigit
1.52 fefe 773: add strftime (ugh!!!)
1.53 olaf 774: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 775: Jeff Garzik contributed a spec file. I put it in contrib and hope
776: everbody knows what to do with it...
777: Olaf checked in a ton of libpthread stuff.
1.55 fefe 778: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 779: add large file backwards compatibility support (so gzip will run on
780: kernel 2.2 and 2.0)
1.57 fefe 781: added shutdown
1.58 fefe 782: added nice
783: added pseudo-locale support for is* (they are now weak aliases,
784: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
785: overwrite the default is* functions.
1.59 fefe 786: added liblatin1.a
1.60 fefe 787: added tzfile implementation (does it work for anyone else?)
1.61 fefe 788: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 789: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
790: Thanks!
1.63 fefe 791: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 792:
1.21 fefe 793: 0.7.2:
794: added several prototypes to already implemented functions and
795: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 796: added prototypes for process group and dup syscalls. Thanks to
797: Abraham again. He also contributed an implementation for daemon(),
798: an ugly BSD hack. I decided to diversify the lib/ directory a
799: little and now created a libugly/ directory for stuff like system()
800: and daemon() ;-)
801: added libstdio and moved all that stdio crap from lib/ there. The
802: idea is to start separating now what we will separate for shared
803: libraries anyway.
1.26 fefe 804: optimized x86 unified-syscall by Olaf.
1.27 fefe 805: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
806: limits.h instead)
807: added remove.c and enough cruft to limits.h to make it compile lzo,
808: lzop and bzip2.
1.28 fefe 809: added mktime, asctime_r, asctime and ctime (needed for gzip).
810: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 811: format some day (man tzfile, ugh!) :-(
1.29 fefe 812: added unlink prototype to unistd.h.
813: added gmtime and gmtime_r.
1.31 fefe 814: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 815: removed readdir glibc compatibility cruft.
1.31 fefe 816: removed stat glibc compatibility cruft.
1.32 fefe 817: oops, my fread was broken for pipes.
1.33 fefe 818: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 819:
1.9 fefe 820: 0.7.1:
1.11 fefe 821: optimized away the static arrays from __ltostr and __lltostr.
822: optimized away the static arrays (and more!) from strtoul and strtoull.
823: added system (by Olaf).
1.12 fefe 824: added tolower and toupper
1.13 fefe 825: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 826: added clone for mips (by Olaf).
827: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 828: added pause for all (by Olaf).
1.17 fefe 829: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 830: added isupper and islower.
831: added putc and putchar as macros.
1.17 fefe 832: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
833: insightful discussions and patches I partially used for the last three)
1.18 fefe 834: added getpriority and setpriority (also by Abraham)
1.19 fefe 835: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 836: oi, setjmp and longjmp were broken on other platforms, too!
837: Thanks to Sébastien Côté for reporting this.
1.9 fefe 838:
839: 0.7:
1.6 olaf 840: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 841: Initial dynamic loading glue for i386, also by Olaf.
842: We don't have a dynamic loader yet, so this is not yet usable.
843: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
844: vsprintf, writev, all by Olaf.
1.2 fefe 845: imported readdir fix from Guillaume. Mhh, can the kernel interface
846: really be this broken?
1.3 fefe 847: Found a kludgy way to detect whether the kernel includes define struct
848: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
849: not work for you, please tell me!
1.4 fefe 850: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 851: Fixed stdio line buffering. The code was already there but I forgot
852: to mark stdio and stdout as line buffered. This should really be
853: done dynamically using isatty, though.
1.8 fefe 854: Removed superfluous "if (1)" in execvp.c
1.1 cvs 855:
856: 0.6.14:
857: *scanf did not append the 0 byte for %s.
858: added creat and changed creat to call open directly instead of open64.
859: did for fread what 0.6.10 did for fwrite.
860: repaired buffered stdio a little (line buffering is still not
861: supported).
862: [All of these bugs have been reported by Guillaume. Thanks!]
863: added __pure__ to strchr and strrchr in <string.h>
864:
865: 0.6.13:
866: included COPYING to make clear that the diet libc is covered by the
867: GNU General Public License (and _not_ the LGPL). That means that
868: you need to obtain a license from me if you want to use the diet
869: libc in a proprietary program that you want to distribute.
870: The x86 unified syscall swapped arguments #4 and #5 and noone
871: noticed until now! Thanks to Guillaume Cottenceau for reporting
872: this!
873: The malloc had a subtle bug with small allocations that could cause
874: segfault. Guillaume reported it, Olaf fixed it.
875:
876: 0.6.12:
877: added assert, statfs and fstatfs
878: added include/net/if.h so fget compiles again.
879:
880: 0.6.11:
881: added putenv.
882:
883: 0.6.10:
884: fixed fwrite. It returned the number of bytes written, not the number
885: of records. Thanks to Albert D. Cahalan for pointing this out.
886: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
887: added brk and sbrk. harold@nb.com.sg made me do it.
888:
889: 0.6.9:
890: fixed execvp not to return on ENOENT
891: did for {open|read|close|seek|tell}dir what I did for stat before.
892: The glibc compatibility part is currently non-functional.
893: fixed white space handling in sscanf " (" would not match " (".
894: fixed printf to accept 'l' flag.
895: fixed getpwuid (ignored last line)
896:
897: 0.6.8:
898: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
899: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
900: added strlcpy and strlcat from OpenBSD.
901: added stat64, fstat64 and lstat64.
902: added endian.h and made ending of strlen.c endianness-aware
903: added string routines size tweak to dietfeatures.h. Most of the
904: string routines have been unrolled. This is up to three times as
905: fast but creates up to three times larger code. Now you can disable
906: the unrolling.
907: added sendfile.
908: I also added pread. It works on x86 and sparc but not on ppc and mips.
909: I have no idea what's going on. strace disagrees with the kernel.
910: Can anyone help? I asked the Linux kernel mailing list for help, too.
911: added a few aliases of the type __libc_open for open. nm on
912: libpthreads.so indicates that we will need them.
913:
914: 0.6.7:
915: the sources now compile without warnings with -Wall.
916: printf now prints "(null)" when %s is passed NULL. This can be
917: removed with WANT_NULL_PRINTF in dietfeatures.h
918: added vfprintf, execl, ttyname.
919: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
920: __dietfstat so they can use the normal kernel struct stat.
921: stat, lstat and fstat are now C wrappers that convert to the glibc
922: struct stat. So we can avoid that overhead for programs that use
923: dietlibc headers.
924:
925: 0.6.6:
926: changed the Makefiles so you can now set CFLAGS on the command line
927: added memccmp (analogous to memccpy) and strncmp.
928: Olaf fixed another bug in the sparc unified syscall.
929: Paul Clifford contributed a C version of his strlen.S that is much
930: more efficient than the previous strlen on all platforms! It also
931: looks like technology from Roswell. ;-}
932: added a "real" stdio. Well, almost. Please contribute!
933: added dietfeatures.h so you can remove features you don't need.
934: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
935: stdio now works with simple programs and minigzip from libz.
936: stdio uses some major trickery to avoid linking the stdio, stderr and
937: stdout (and reserving space for them) when they are not used.
938:
939: 0.6.5:
940: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
941: most of them bugs in the new header files, but also missing sigset
942: functions.
943: Paul Clifford contributed an assembly strlen.S for ARM and fixed
944: several bugs.
945: Fixed ppc/setjmp and mips/pipe.
946: Olaf contributed a new sparc unified syscall.
947:
948: 0.6.4:
949: declared is* static inline in getservent.
950: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
951: changed strlen to return 0 when passed NULL.
952: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
953: Scientist who actually implemented this without access to a MIPS
954: box, just from reading the architecture manual. And it worked out
955: of the box.
956: started a set of system includes, mainly so that I can use lcc and
957: my alpha-linux cross compiler (which is unable to cross-compile
958: glibc). diet libc can now be compiled without any include files
959: from a normal libc. The includes do declare more than diet libc
960: currently delivers and they are still far from complete for real
961: applications.
962: I will only add assembly versions that are smaller _and_ faster than
963: the C version. Larger routines are only accepted if they are called
964: very often and are substantially faster.
965: added i386 assembly strchr, which is smaller and faster than the old
966: version. It is, however, larger than the version contributed by
967: proton (thanks, anyway).
968: added i386 strlen (31% faster, 14% smaller)
969: "make t" will now create a map file called "mapfile".
970:
971: 0.6.3:
972: added sys_errlist, strerror and perror
973: added isblank
974: added atol
975:
976: 0.6.2:
977: mmap for ARM didn't compile. Thanks, Paul!
978:
979: 0.6.1:
980: split mmap into the architecture specific subdirectories.
981: getenv now copes with environ==NULL, thanks Paul Clifford.
982: Paul also contributed a smaller ARM startup code.
983:
984: 0.6:
985: strcat returned the wrong result. Thanks, Dietz Pröpper.
986: strtod now understands a negative exponent (oops, thanks Bertram Barth)
987: Port to arm-linux-gnu, but on the Netwinder I use for testing the
988: __dtostr does not work (I have no idea why!)
989: The MIPS port now uses (much smaller) non-PIC code. That means that
990: the applications you link against diet libc also have to be compiled
991: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
992: Thanks to Ralf Bächle for helping me with this!
993: I made subdirectories for the architectures and use VPATH to override
994: VPATH so that make finds the source file automatically. That should
995: simplify the sources greatly.
996: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
997: ARM and MIPS now also have setjmp and longjmp
998: "compile" and "load" are now make targets. Use them for djb programs.
999: added contrib/elftrunc.c which will remove unnecessary ELF headers.
1000: Again, contributed from Olaf. Great work!
1001:
1002: 0.5.12:
1003: printf also does signed numbers.
1004: If you don't use atexit, dietlibc now does not link exit, only _exit.
1005: *printf now correctly returns the number of bytes written.
1006: Olaf contributed experimental sscanf and vsscanf implementations.
1007: If passed NULL as buffer, snprintf will not write anything but still
1008: return the number of bytes it would have written.
1009: Initial MIPS port! (Oh, the agony!)
1010: No setjmp and longjmp support yet! Please contribute!
1011: I even implemented unified syscalls for MIPS. Still, MIPS code is
1012: almost twice the size of SPARC code. If anyone knows why: please
1013: tell me!
1014:
1015: 0.5.11:
1016: I implemented new unified syscalls for x86, sparc and ppc, this time based
1017: on .s files and not .c files, and I moved the syscalls into
1018: subdirectores to clean the dietlibc sources up a little.
1019: A binary consisting of printf("%s is %d\n","olaf",23) is now
1020: 2864 bytes on sparc
1021: 2488 bytes on intel
1022: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
1023: to make a few more applications work.
1024: Olaf Dreesen also implemented some unified syscall stuff for x86.
1025: He discovered that with our unified syscall interface it actually
1026: costs <10 bytes total to make all system calls thread safe!
1027: I implemented atexit() (can register up to 4 callbacks).
1028: I implemented strtod and __dtostr (the opposite). Now we can add
1029: floating point support to vsnprintf and sscanf!
1030:
1031: 0.5.10:
1032: I actually saw that I can not only merge the errno handling code of
1033: the system calls on x86, I can also merge the rest (including the
1034: arguments) except for setting the system call number. All those
1035: system calls are now just a jump to a unified system call handler.
1036: I got rid of x86openclose again. The savings are substantial:
1037: chown from embutils went from 7664 to 7184 bytes!
1038: If I'd move the system call wrappers to assembly language, I could
1039: even reduce the alignment (does not matter since it's just a jump
1040: anyway) and get rid of the "ret" behind each jump (one byte per
1041: system call!)
1042:
1043: 0.5.9:
1044: added memchr, strpbrk, strstr, strtol, isspace (hehe)
1045: fixed strdup
1046: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
1047: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
1048: (no signed integers, only strings and unsigned integers (but
1049: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
1050: that code must be wonderful, I don't understand it at all *bg*)
1051: Olaf's printf does understand padding like in "%08d" and "%8d" and
1052: automatically pads pointers with '0'.
1053: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
1054: Thanks to proton for inspiration on this.
1055: The new x86 start code also does not reference exit any more, thus saving
1056: 64 bytes for executables that don't call exit explicitly.
1057: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1058: Moved errno and environ to start.S, saving no byte binary size but
1059: speeding up compilation and slightly shortening dietlibc.a ;-)
1060: For x86: joined open and close into one assembler file, sharing the
1061: errno handling. This is a feasibility test and it actually saves a
1062: few bytes. I think I will reimplement the _syscall[1-6] macros on
1063: all platforms now to share the errno handling code for them.
1064:
1065: 0.5.8:
1066: fixed strchr to be able to look for 0.
1067:
1068: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1069: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1070: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1071: contributed by Olaf Dreesen)
1072:
1073: added execvp, getcwd
1074:
1075: fixed __xmknod
1076:
1077: Note: can it be that the ftw interface really is so broken that I
1078: cannot implement it without having to implement some searching data
1079: structure? I included an experimental ftw implementation that will
1080: not follow symlinks.
1081:
1082: 0.5.7:
1083: oops, if_nametoindex was broken!
1084:
1085: 0.5.6:
1086: ported to ppc-linux.
1087: fixed i386 sigsetjmp (I mistyped the function name)
1088: included sigjmp.c
1089:
1090: 0.5.5:
1091: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1092: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1093: I fixed it now.
1094: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1095: fixed readdir to use getdents and not the intel inline asm
1096:
1097: 0.5.4:
1098: ported to sparclinux (sparc32 only). Beware: does not work yet.
1099: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1100:
1101: 0.5.3:
1102: added tcsetattr and getenv to compile e3
1103:
1104: 0.5.2:
1105: added vhangup, tcgetattr, isatty and memcmp for fgetty
1106: (http://www.fefe.de/fgetty/)
1107: added localtime from uC-libc.
1108:
1109: 0.5.1:
1110: stat and friends actually work now. Yuck! Another case of
1111: translation between kernel and userland. Why can't the kernel
1112: people and the libc people simply agree on a standard?
1113: removed many unnecessary includes to speed up compilation.
1114: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1115: inlined socketcall to reduce code size.
1116: "load" and "compile" are examples for djb code.
1117:
1118: 0.5:
1119: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1120: each object file is now treated with "strip -x -R .note -R .comment"
1121: split each system call into a separate object file
1122: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1123:
1124: 0.4.1:
1125: oops, the strchr implementation was wrong. Thanks Jens Laas!
1126:
1127: 0.4:
1128: copied opendir and friends from uC-libc.
1129: added getservent and getservby* in gerservent.c
1130:
1131: 0.3:
1132: remove readdir system call
1133: added getdents system call
1134: added getpwnam/getpwuid implementation in getpwnam.c
1135: added a few string functions (in str*.c)
