1.261 fefe 325: sys/ipc.h now includes sys/types.h
1.262 olaf 326: Olaf: started to make the sparc64 port
1.263 fefe 327: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 328:
1.224 fefe 329: 0.15:
1.225 fefe 330: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 331: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 332: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
333: thread-safe!
1.228 fefe 334: remove vfork and add alarm to dynamic syscalls.
335: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 336: The MD5 code generated unaligned accesses when passed an unaligned
337: pointer on little endian ARM and MIPS.
338: MIPS unified syscall didn't compile anymore.
339: Put up new mipsel target to cross compile for little endian mips.
340: The mips target will again explicitly set endianness to big endian.
341: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 342: Duh, when we removed return0, we broke tzset when the time zone parser
343: was disabled. Uwe Ohse noticed this. Thanks!
344: Fix gethostbyname to match host names case insensitively in /etc/hosts.
345: Oops, this was reported 6 weeks ago but I overlooked the email.
346: Thanks, Denis Rachal!
1.231 fefe 347: vsnprintf's zero termination was broken.
1.233 fefe 348: Uwe Ohse found a few more bugs:
349: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
350: does it correctly.
351: Make inet_aton use strtoul instead of strtol
352: fdopen would close the file descriptor if it could not malloc the
353: buffer.
354: strftime updates.
355: Make _FILE_OFFSET_BITS includes -Wundef clean
356: Andre found a typo in endian.h for big endian mips
1.234 fefe 357: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 358: strstr(whatever,"") returned NULL, not whatever. Found by a new test
359: suite entry for strstr that I wrote.
1.245 fefe 360: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 361: add <asm/sigcontext.h> for profiling support.
362: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 363: an i386 assembler getenv implementation (roughly half the size)
364: add grantpt, ptsname, unlockpt
1.236 fefe 365: add a getenv test suite entry.
1.238 fefe 366: Andre contributed an ARM assembler md5 implementation and he fixed mmap
367: on ARM.
368: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 369: getservent_r did not parse lines without aliases. Thanks, Jaroslav
370: Macodiseas!
1.240 fefe 371: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 372: removed annoying -Wconversion gcc switch
1.242 fefe 373: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 374: Kurt Garloff sent these diffs:
375: add fdatasync (and make it a pthread cancellation point)
376: numerous alpha issues, like using .quad instead of .long for
377: offsets, change strip to -strip in Makefile (so a failing strip does
378: not abort the make), try to be more friendly to the gcc 2.96 that
379: SuSE 7.1 AXP ships with.
1.224 fefe 380:
1.209 fefe 381: 0.14:
1.224 fefe 382: fix brk again (missing __brk, trivial oversight)
1.210 fefe 383: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
384: Thomas Ogrisegg!
1.211 fefe 385: Thomas also contributed a PA-RISC port including testandset, so
386: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 387: made the fake locale more believable.
388: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 389: moved _exit into the unified syscall on x86.
1.214 fefe 390: Uwe Ohse found many more bugs:
391: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
392: liblatin1 was more or less completely broken if you gave it chars as
393: arguments, not ints (signedness). execvp had a buffer overflow in
394: case a PATH element exceeded PATH_MAX, but it's not a security
395: problem since setuid programs need to set their path to some known
396: value anyway.
1.219 fefe 397: hasmntopt did not work with foo=bar style options
1.217 fefe 398: Uwe also improved ftw's stack usage.
1.214 fefe 399: Put movl instead of popl rationale in comment in i386/unified.S since
400: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 401: I discovered __attribute__((malloc)) and started using it. For gcc 3,
402: it improves the optimizer when functions return malloced pointers.
1.216 fefe 403: Steven Rostedt pointed out that my setvbuf was broken with regard to
404: size==0 and sent a patch to fix it.
1.218 fefe 405: Thomas Ogrisegg made setenv smaller.
1.220 olaf 406: Olaf: implemented the parisc clone and an atomic testandset, modified the
407: libpthread to respect the parisc UPgrowing stack. still non functional,
408: because the unified syscall uses errno :(
1.221 fefe 409: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 410: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
411: don't write anything which was no longer the case. It also
412: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 413: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 414:
1.193 fefe 415: 0.13:
1.194 fefe 416: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 417: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 418: Olaf: port to S/390!
1.463 leitner 419: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 420: res_query did not initialize last
1.199 fefe 421: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 422: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 423: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 424: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 425: rewrote __dtostr (it also has one more argument now)
1.205 fefe 426: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 427: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
428: fix strncat for the case where n == 0 (security implications?)
429: fix bsearch (it didn't find the very last element in the array, same
430: bug in both the C and the i386 assembly version).
1.205 fefe 431: fixed FNM_PATHNAME in fnmatch
1.204 fefe 432: fix brk (the syscall was documented incorrectly in the Linux man page)
433: Thanks, Thomas Ogrisegg!
1.205 fefe 434: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 435: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 436: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 437:
1.164 fefe 438: 0.12:
439: more contributions from Frank Klemm.
1.165 fefe 440: iconv can now do UCS-2, too.
1.167 fefe 441: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 442: Lots of bug fixes, and several more i386 specific versions of common
443: routines to make them smaller.
1.168 fefe 444: add memmem (a GNU extension that looks useful)
1.170 fefe 445: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 446: add pivot_root syscall, %n for *scanf.
1.169 fefe 447: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 448: add Frank Klemm's optimized md5
1.172 fefe 449: add -Os option to diet (see diet.1).
1.173 fefe 450: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 451: add 32-bit uid/gid syscalls.
1.175 fefe 452: add rand48 (thanks, Johannes Kloos)
1.176 fefe 453: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 454: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
455: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
456: fix gethostent alias list termination. Major oops.
1.178 fefe 457: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 458: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 459: DNS will now properly signal errors and set h_errno.
460: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 461: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
462: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
463: external reference to a symbol that is only in the diet libc. So,
464: when you accidentally link a diet libc compiled object file against
465: glibc, the linker will barf. This will bloat your object files, but
466: you can remove all the references with "strip -R .note" from
467: the binaries in the end (which you should do anyway).
1.182 fefe 468: fix ARM unified syscall (select did not work).
1.183 fefe 469: add getpwent_r ala glibc and replace getpwent
470: do the same for getgrent and getspent
471: remove entlib (new code is smaller)
1.184 fefe 472: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 473: add getpwnam_r and getpwuid_r
1.186 fefe 474: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 475: Olaf muddled with the dynamic linker. It's a clean-room
476: implementation in the sense that it once worked for Olaf in a clean
477: room ;)
1.188 fefe 478: add if_nameindex and if_freenameindex.
479: fixed arm unified syscalls to work with current binutils (; is no
480: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 481: changed all st_[cma]time types to signed long so comparisons against
482: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 483: fixed two bugs regarding ungetc.
484: add getusershell, setusershell, endusershell (for vs_ftpd)
485: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 486: fixed strftime (was completely hosed)
1.192 fefe 487: added real make install target
1.164 fefe 488:
1.115 fefe 489: 0.11:
490: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 491: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 492: add floor, ceil and memchr prototypes.
493: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 494: cleaner errno vs __errno_location handling
495: add placeholder iconv (iconv_open will always return EINVAL)
496: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
497: initialization of getaddrinfo.
1.119 fefe 498: fix vsnprintf %X (printed lower case)
1.120 fefe 499: I wrote a new getopt. It appears to actually work (it is POSIX
500: compliant, it does not sort argv like the GNU version) and is only
501: a little over 300 bytes on x86.
1.121 fefe 502: Guillaume Cottenceau just wrote me that strncat should be even more
503: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 504: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 505: Fix regexec offset return. autoconf now believes that diet libc has
506: POSIX regular expressions.
1.123 fefe 507: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 508: Fix regular expression match for x* when there is no x at all.
1.125 fefe 509: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 510: Add %h to vsnprintf.
1.127 fefe 511: Add FAQ.
1.128 fefe 512: Make %h work for signed numbers and add %hh to vsnprintf.
513: initgroups ignored the group argument :-(
514: remove printf references and nested functions from glob.
1.129 fefe 515: added an errno in libpthread that will display a prominent linker
516: warning.
1.131 fefe 517: started getting rid of kernel headers. Big task! :-(
1.130 fefe 518: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 519: Olaf: added a lot of code in libdl (not yet complete), changed the
520: startup code to make it work with his libdl and ld.so (needs still work
521: too)
1.134 fefe 522: __dns_readstartfiles only took the first domain or search path.
523: Thanks, Anthony de Boer
1.133 olaf 524: Olaf: added clone and a new unified_syscall for PowerPC
525: also dynlinker is now available (i386 only at this time)
1.135 fefe 526: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 527: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 528: fixed word delimiters in regex (they looked for space, i.e. "," did
529: not work as delimiter)
1.138 fefe 530: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 531: added mkdtemp.
1.142 fefe 532: Uwe Ohse reported all of the following bugs:
533: ttyname should return 0 if !isatty.
534: realpath returns NULL if "." cannot be opened
535: putenv erroneously accepted (and mishandled) entries without "=".
536: popen returned 255 instead of 127 if /bin/sh could not be run.
537: fgetc did not set the internal EOF indicator on EOF.
538: bsearch contained an assumption about integer arithmetic overflow
539: behavior.
540: system did not set SIGCHLD and thus contained a race.
541: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 542: daemon did not check whether open returns an fd below 3
543: perror did not save errno.
1.144 olaf 544: Olaf: Peter Jones reported some problems with perror; strerror had the
545: same problem.
546: Peter also posted a patch to atexit/exit. With some modifications it is
547: now implemented.
1.145 fefe 548: Unbuffered stdio and ungetc can no longer be disabled. I will try to
549: implement part of it using ELF weak symbols.
1.146 fefe 550: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 551: Added overflow handling for strtoul and strtol.
1.149 fefe 552: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
553: it before falling back to DNS if enabled.
1.150 fefe 554: Added a littie backwards compatibility cruft for gpm (man, do these
555: sources stink!)
1.151 fefe 556: Added openpty.
1.152 fefe 557: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 558: Fix fseek return value.
1.155 fefe 559: Add dirname and basename.
1.156 fefe 560: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 561: Fixed getservent (did not allow _ and - in the aliases).
562: Thanks, Oden Eriksson
1.158 fefe 563: Added a float.h so configure believes we have ANSI header files.
564: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 565: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 566: scanf and printf function implementations
1.160 fefe 567: Imported a few more functions and optimizations from Frank Klemm (he
568: also rewrote dtostr to have more precision)
1.161 olaf 569: Olaf: checked in a new sig* function family (based on rt_sig*).
570: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 571: Made rudimentary iconv that can convert back and forth between
572: iso-8859-1, utf-8 and ucs-4 (for debugging).
573: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 574:
1.74 fefe 575: 0.10:
576: update getpagesize.
577: add personality.
1.75 fefe 578: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 579: add putchar (apparently arm-linux-gcc will substitute printf("\n")
580: with putchar('\n') behind your back...?!
1.77 fefe 581: import include/scsi/ from glibc.
1.78 fefe 582: add iopl.
1.80 fefe 583: add execl and sigdelset prototypes.
584: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 585: add RPC headers (no code yet).
1.82 fefe 586: add mlockall, munlockall
1.83 fefe 587: make "diet gcc foo.c" work.
588: added Sun RPC code and removed as many warnings as possible in a
589: heroic act of self-mutilation.
590: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 591: added getpass. mount from util-linux actually compiles now!
592: fix the sig*set routines. mount actually works now *bg*
593: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 594: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 595: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 596: add res_init.
597: add asprintf (ugh, what an ugly function).
1.89 fefe 598: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 599: add ut_name alias to ut_host in struct utmp.
600: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 601: add sysinfo, recvmsg, sendmsg.
1.93 fefe 602: add endmntent, getmntent, setmntent.
1.94 fefe 603: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 604: add setenv.
605: remove __restrict from mntent.h, add __restrict__ removal alias for
606: older gcc versions in sys/cdefs.h.
607: add rlim_t, sig_atomic_t declarations.
608: add sigsetjmp #define for __sigsetjmp (oops).
609: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 610: add a gruesome hack to printf floating point to accept %f and kludge
611: together support for %.2f. Don't look at the code, please!
1.98 fefe 612: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 613: imported fix for entlib by Jeff Garzik.
1.100 fefe 614: add glob implementation from Guillaume Cottenceau (Thanks!!)
615: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 616: add REG_ICASE and word start/end handling to my regular expressions.
617: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 618: wrap getcwd to comply to man page (the syscall returns the number of
619: bytes, not the buffer)
620: add realpath.
1.103 fefe 621: fix vfprintf.
1.104 fefe 622: fix *scanf %s zero termination.
623: add abs, labs, llabs.
1.105 fefe 624: add <sys/io.h>, ioperm syscall.
625: add flock to <sys/file.h>
1.106 fefe 626: fixes to bsearch and the regular expressions.
1.107 fefe 627: add fake herror.
1.108 fefe 628: add scandir and alphasort.
1.109 fefe 629: add killpg
1.110 fefe 630: implemented a gross hack to make libpthread compile when
631: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 632: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 633: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 634: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
635: for sending a patch.
1.114 fefe 636: add getserv*.
637: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
638: "search" from resolv.conf.
1.74 fefe 639:
1.73 fefe 640: 0.9:
1.65 fefe 641: fixed initgroups (oops)
1.66 fefe 642: Cleanup appending file open for stdio (thanks, James Antill)
643: imported vfprintf fix from James Antill.
1.67 fefe 644: add fnmatch
645: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 646: Olaf added character classes to *scanf.
1.69 fefe 647: Put object and library files into a separate directory (bin-$ARCH).
648: Add "cross" make target to make all architectures.
649: Add "diet" program and man page.
1.70 fefe 650: Add getgrnam, getgrgid
1.71 fefe 651: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 652: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 653:
1.64 fefe 654: 0.8:
1.34 fefe 655: vsnprintf(0,...) estimated the length of strings with a padding width
656: incorrectly.
1.35 fefe 657: new reboot() from Olaf.
1.36 fefe 658: added prototypes for getsockopt and setsockopt.
1.39 fefe 659: added experimental sem* and shm*
1.38 fefe 660: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 661: added setvbuf (only changes mode, not buffer)
1.41 fefe 662: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
663: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 664: added qsort() and bsearch(). Benchmark on 1000 random ints:
665: glibc: 679414 cycles qsort and 3352 cycles bsearch
666: diet libc: 300010 cycles qsort, 553 cycles bsearch
667: I have no idea why glibc is so slow.
1.43 fefe 668: added __isnan (references by libm.a from glibc).
669: added popen() and pclose(). Now the diet libc can link slsh (from
670: S-Lang!)
1.44 fefe 671: corrected usleep. It was more of an msleep until now.
1.45 fefe 672: corrected __dtostr (it looped when trying to format "0.0").
673: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 674: added ungetc (does it work?)
1.47 fefe 675: added inet_aton (yuck!)
1.50 fefe 676: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 677: added h_errno and __h_errno_location
678: added inet_ntoa
1.49 fefe 679: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 680: add bcopy, index, rindex macros
681: add isgraph and isxdigit
1.52 fefe 682: add strftime (ugh!!!)
1.53 olaf 683: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 684: Jeff Garzik contributed a spec file. I put it in contrib and hope
685: everbody knows what to do with it...
686: Olaf checked in a ton of libpthread stuff.
1.55 fefe 687: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 688: add large file backwards compatibility support (so gzip will run on
689: kernel 2.2 and 2.0)
1.57 fefe 690: added shutdown
1.58 fefe 691: added nice
692: added pseudo-locale support for is* (they are now weak aliases,
693: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
694: overwrite the default is* functions.
1.59 fefe 695: added liblatin1.a
1.60 fefe 696: added tzfile implementation (does it work for anyone else?)
1.61 fefe 697: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 698: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
699: Thanks!
1.63 fefe 700: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 701:
1.21 fefe 702: 0.7.2:
703: added several prototypes to already implemented functions and
704: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 705: added prototypes for process group and dup syscalls. Thanks to
706: Abraham again. He also contributed an implementation for daemon(),
707: an ugly BSD hack. I decided to diversify the lib/ directory a
708: little and now created a libugly/ directory for stuff like system()
709: and daemon() ;-)
710: added libstdio and moved all that stdio crap from lib/ there. The
711: idea is to start separating now what we will separate for shared
712: libraries anyway.
1.26 fefe 713: optimized x86 unified-syscall by Olaf.
1.27 fefe 714: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
715: limits.h instead)
716: added remove.c and enough cruft to limits.h to make it compile lzo,
717: lzop and bzip2.
1.28 fefe 718: added mktime, asctime_r, asctime and ctime (needed for gzip).
719: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 720: format some day (man tzfile, ugh!) :-(
1.29 fefe 721: added unlink prototype to unistd.h.
722: added gmtime and gmtime_r.
1.31 fefe 723: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 724: removed readdir glibc compatibility cruft.
1.31 fefe 725: removed stat glibc compatibility cruft.
1.32 fefe 726: oops, my fread was broken for pipes.
1.33 fefe 727: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 728:
1.9 fefe 729: 0.7.1:
1.11 fefe 730: optimized away the static arrays from __ltostr and __lltostr.
731: optimized away the static arrays (and more!) from strtoul and strtoull.
732: added system (by Olaf).
1.12 fefe 733: added tolower and toupper
1.13 fefe 734: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 735: added clone for mips (by Olaf).
736: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 737: added pause for all (by Olaf).
1.17 fefe 738: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 739: added isupper and islower.
740: added putc and putchar as macros.
1.17 fefe 741: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
742: insightful discussions and patches I partially used for the last three)
1.18 fefe 743: added getpriority and setpriority (also by Abraham)
1.19 fefe 744: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 745: oi, setjmp and longjmp were broken on other platforms, too!
746: Thanks to Sébastien Côté for reporting this.
1.9 fefe 747:
748: 0.7:
1.6 olaf 749: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 750: Initial dynamic loading glue for i386, also by Olaf.
751: We don't have a dynamic loader yet, so this is not yet usable.
752: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
753: vsprintf, writev, all by Olaf.
1.2 fefe 754: imported readdir fix from Guillaume. Mhh, can the kernel interface
755: really be this broken?
1.3 fefe 756: Found a kludgy way to detect whether the kernel includes define struct
757: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
758: not work for you, please tell me!
1.4 fefe 759: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 760: Fixed stdio line buffering. The code was already there but I forgot
761: to mark stdio and stdout as line buffered. This should really be
762: done dynamically using isatty, though.
1.8 fefe 763: Removed superfluous "if (1)" in execvp.c
1.1 cvs 764:
765: 0.6.14:
766: *scanf did not append the 0 byte for %s.
767: added creat and changed creat to call open directly instead of open64.
768: did for fread what 0.6.10 did for fwrite.
769: repaired buffered stdio a little (line buffering is still not
770: supported).
771: [All of these bugs have been reported by Guillaume. Thanks!]
772: added __pure__ to strchr and strrchr in <string.h>
773:
774: 0.6.13:
775: included COPYING to make clear that the diet libc is covered by the
776: GNU General Public License (and _not_ the LGPL). That means that
777: you need to obtain a license from me if you want to use the diet
778: libc in a proprietary program that you want to distribute.
779: The x86 unified syscall swapped arguments #4 and #5 and noone
780: noticed until now! Thanks to Guillaume Cottenceau for reporting
781: this!
782: The malloc had a subtle bug with small allocations that could cause
783: segfault. Guillaume reported it, Olaf fixed it.
784:
785: 0.6.12:
786: added assert, statfs and fstatfs
787: added include/net/if.h so fget compiles again.
788:
789: 0.6.11:
790: added putenv.
791:
792: 0.6.10:
793: fixed fwrite. It returned the number of bytes written, not the number
794: of records. Thanks to Albert D. Cahalan for pointing this out.
795: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
796: added brk and sbrk. harold@nb.com.sg made me do it.
797:
798: 0.6.9:
799: fixed execvp not to return on ENOENT
800: did for {open|read|close|seek|tell}dir what I did for stat before.
801: The glibc compatibility part is currently non-functional.
802: fixed white space handling in sscanf " (" would not match " (".
803: fixed printf to accept 'l' flag.
804: fixed getpwuid (ignored last line)
805:
806: 0.6.8:
807: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
808: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
809: added strlcpy and strlcat from OpenBSD.
810: added stat64, fstat64 and lstat64.
811: added endian.h and made ending of strlen.c endianness-aware
812: added string routines size tweak to dietfeatures.h. Most of the
813: string routines have been unrolled. This is up to three times as
814: fast but creates up to three times larger code. Now you can disable
815: the unrolling.
816: added sendfile.
817: I also added pread. It works on x86 and sparc but not on ppc and mips.
818: I have no idea what's going on. strace disagrees with the kernel.
819: Can anyone help? I asked the Linux kernel mailing list for help, too.
820: added a few aliases of the type __libc_open for open. nm on
821: libpthreads.so indicates that we will need them.
822:
823: 0.6.7:
824: the sources now compile without warnings with -Wall.
825: printf now prints "(null)" when %s is passed NULL. This can be
826: removed with WANT_NULL_PRINTF in dietfeatures.h
827: added vfprintf, execl, ttyname.
828: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
829: __dietfstat so they can use the normal kernel struct stat.
830: stat, lstat and fstat are now C wrappers that convert to the glibc
831: struct stat. So we can avoid that overhead for programs that use
832: dietlibc headers.
833:
834: 0.6.6:
835: changed the Makefiles so you can now set CFLAGS on the command line
836: added memccmp (analogous to memccpy) and strncmp.
837: Olaf fixed another bug in the sparc unified syscall.
838: Paul Clifford contributed a C version of his strlen.S that is much
839: more efficient than the previous strlen on all platforms! It also
840: looks like technology from Roswell. ;-}
841: added a "real" stdio. Well, almost. Please contribute!
842: added dietfeatures.h so you can remove features you don't need.
843: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
844: stdio now works with simple programs and minigzip from libz.
845: stdio uses some major trickery to avoid linking the stdio, stderr and
846: stdout (and reserving space for them) when they are not used.
847:
848: 0.6.5:
849: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
850: most of them bugs in the new header files, but also missing sigset
851: functions.
852: Paul Clifford contributed an assembly strlen.S for ARM and fixed
853: several bugs.
854: Fixed ppc/setjmp and mips/pipe.
855: Olaf contributed a new sparc unified syscall.
856:
857: 0.6.4:
858: declared is* static inline in getservent.
859: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
860: changed strlen to return 0 when passed NULL.
861: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
862: Scientist who actually implemented this without access to a MIPS
863: box, just from reading the architecture manual. And it worked out
864: of the box.
865: started a set of system includes, mainly so that I can use lcc and
866: my alpha-linux cross compiler (which is unable to cross-compile
867: glibc). diet libc can now be compiled without any include files
868: from a normal libc. The includes do declare more than diet libc
869: currently delivers and they are still far from complete for real
870: applications.
871: I will only add assembly versions that are smaller _and_ faster than
872: the C version. Larger routines are only accepted if they are called
873: very often and are substantially faster.
874: added i386 assembly strchr, which is smaller and faster than the old
875: version. It is, however, larger than the version contributed by
876: proton (thanks, anyway).
877: added i386 strlen (31% faster, 14% smaller)
878: "make t" will now create a map file called "mapfile".
879:
880: 0.6.3:
881: added sys_errlist, strerror and perror
882: added isblank
883: added atol
884:
885: 0.6.2:
886: mmap for ARM didn't compile. Thanks, Paul!
887:
888: 0.6.1:
889: split mmap into the architecture specific subdirectories.
890: getenv now copes with environ==NULL, thanks Paul Clifford.
891: Paul also contributed a smaller ARM startup code.
892:
893: 0.6:
894: strcat returned the wrong result. Thanks, Dietz Pröpper.
895: strtod now understands a negative exponent (oops, thanks Bertram Barth)
896: Port to arm-linux-gnu, but on the Netwinder I use for testing the
897: __dtostr does not work (I have no idea why!)
898: The MIPS port now uses (much smaller) non-PIC code. That means that
899: the applications you link against diet libc also have to be compiled
900: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
901: Thanks to Ralf Bächle for helping me with this!
902: I made subdirectories for the architectures and use VPATH to override
903: VPATH so that make finds the source file automatically. That should
904: simplify the sources greatly.
905: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
906: ARM and MIPS now also have setjmp and longjmp
907: "compile" and "load" are now make targets. Use them for djb programs.
908: added contrib/elftrunc.c which will remove unnecessary ELF headers.
909: Again, contributed from Olaf. Great work!
910:
911: 0.5.12:
912: printf also does signed numbers.
913: If you don't use atexit, dietlibc now does not link exit, only _exit.
914: *printf now correctly returns the number of bytes written.
915: Olaf contributed experimental sscanf and vsscanf implementations.
916: If passed NULL as buffer, snprintf will not write anything but still
917: return the number of bytes it would have written.
918: Initial MIPS port! (Oh, the agony!)
919: No setjmp and longjmp support yet! Please contribute!
920: I even implemented unified syscalls for MIPS. Still, MIPS code is
921: almost twice the size of SPARC code. If anyone knows why: please
922: tell me!
923:
924: 0.5.11:
925: I implemented new unified syscalls for x86, sparc and ppc, this time based
926: on .s files and not .c files, and I moved the syscalls into
927: subdirectores to clean the dietlibc sources up a little.
928: A binary consisting of printf("%s is %d\n","olaf",23) is now
929: 2864 bytes on sparc
930: 2488 bytes on intel
931: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
932: to make a few more applications work.
933: Olaf Dreesen also implemented some unified syscall stuff for x86.
934: He discovered that with our unified syscall interface it actually
935: costs <10 bytes total to make all system calls thread safe!
936: I implemented atexit() (can register up to 4 callbacks).
937: I implemented strtod and __dtostr (the opposite). Now we can add
938: floating point support to vsnprintf and sscanf!
939:
940: 0.5.10:
941: I actually saw that I can not only merge the errno handling code of
942: the system calls on x86, I can also merge the rest (including the
943: arguments) except for setting the system call number. All those
944: system calls are now just a jump to a unified system call handler.
945: I got rid of x86openclose again. The savings are substantial:
946: chown from embutils went from 7664 to 7184 bytes!
947: If I'd move the system call wrappers to assembly language, I could
948: even reduce the alignment (does not matter since it's just a jump
949: anyway) and get rid of the "ret" behind each jump (one byte per
950: system call!)
951:
952: 0.5.9:
953: added memchr, strpbrk, strstr, strtol, isspace (hehe)
954: fixed strdup
955: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
956: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
957: (no signed integers, only strings and unsigned integers (but
958: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
959: that code must be wonderful, I don't understand it at all *bg*)
960: Olaf's printf does understand padding like in "%08d" and "%8d" and
961: automatically pads pointers with '0'.
962: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
963: Thanks to proton for inspiration on this.
964: The new x86 start code also does not reference exit any more, thus saving
965: 64 bytes for executables that don't call exit explicitly.
966: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
967: Moved errno and environ to start.S, saving no byte binary size but
968: speeding up compilation and slightly shortening dietlibc.a ;-)
969: For x86: joined open and close into one assembler file, sharing the
970: errno handling. This is a feasibility test and it actually saves a
971: few bytes. I think I will reimplement the _syscall[1-6] macros on
972: all platforms now to share the errno handling code for them.
973:
974: 0.5.8:
975: fixed strchr to be able to look for 0.
976:
977: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
978: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
979: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
980: contributed by Olaf Dreesen)
981:
982: added execvp, getcwd
983:
984: fixed __xmknod
985:
986: Note: can it be that the ftw interface really is so broken that I
987: cannot implement it without having to implement some searching data
988: structure? I included an experimental ftw implementation that will
989: not follow symlinks.
990:
991: 0.5.7:
992: oops, if_nametoindex was broken!
993:
994: 0.5.6:
995: ported to ppc-linux.
996: fixed i386 sigsetjmp (I mistyped the function name)
997: included sigjmp.c
998:
999: 0.5.5:
1000: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1001: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1002: I fixed it now.
1003: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1004: fixed readdir to use getdents and not the intel inline asm
1005:
1006: 0.5.4:
1007: ported to sparclinux (sparc32 only). Beware: does not work yet.
1008: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1009:
1010: 0.5.3:
1011: added tcsetattr and getenv to compile e3
1012:
1013: 0.5.2:
1014: added vhangup, tcgetattr, isatty and memcmp for fgetty
1015: (http://www.fefe.de/fgetty/)
1016: added localtime from uC-libc.
1017:
1018: 0.5.1:
1019: stat and friends actually work now. Yuck! Another case of
1020: translation between kernel and userland. Why can't the kernel
1021: people and the libc people simply agree on a standard?
1022: removed many unnecessary includes to speed up compilation.
1023: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1024: inlined socketcall to reduce code size.
1025: "load" and "compile" are examples for djb code.
1026:
1027: 0.5:
1028: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1029: each object file is now treated with "strip -x -R .note -R .comment"
1030: split each system call into a separate object file
1031: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1032:
1033: 0.4.1:
1034: oops, the strchr implementation was wrong. Thanks Jens Laas!
1035:
1036: 0.4:
1037: copied opendir and friends from uC-libc.
1038: added getservent and getservby* in gerservent.c
1039:
1040: 0.3:
1041: remove readdir system call
1042: added getdents system call
1043: added getpwnam/getpwuid implementation in getpwnam.c
1044: added a few string functions (in str*.c)
1045:
