281: pointer on little endian ARM and MIPS.
282: MIPS unified syscall didn't compile anymore.
283: Put up new mipsel target to cross compile for little endian mips.
284: The mips target will again explicitly set endianness to big endian.
285: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 286: Duh, when we removed return0, we broke tzset when the time zone parser
287: was disabled. Uwe Ohse noticed this. Thanks!

1.236 fefe 309: add a getenv test suite entry.
1.238 fefe 310: Andre contributed an ARM assembler md5 implementation and he fixed mmap
311: on ARM.

1.243 fefe 318: Kurt Garloff sent these diffs:
319: add fdatasync (and make it a pthread cancellation point)
320: numerous alpha issues, like using .quad instead of .long for
321: offsets, change strip to -strip in Makefile (so a failing strip does
322: not abort the make), try to be more friendly to the gcc 2.96 that
323: SuSE 7.1 AXP ships with.
1.224 fefe 324:
1.209 fefe 325: 0.14:
1.224 fefe 326: fix brk again (missing __brk, trivial oversight)
1.210 fefe 327: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
328: Thomas Ogrisegg!
1.211 fefe 329: Thomas also contributed a PA-RISC port including testandset, so
330: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 331: made the fake locale more believable.
332: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 333: moved _exit into the unified syscall on x86.
1.214 fefe 334: Uwe Ohse found many more bugs:
335: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
336: liblatin1 was more or less completely broken if you gave it chars as
337: arguments, not ints (signedness). execvp had a buffer overflow in
338: case a PATH element exceeded PATH_MAX, but it's not a security
339: problem since setuid programs need to set their path to some known
340: value anyway.
1.219 fefe 341: hasmntopt did not work with foo=bar style options
1.217 fefe 342: Uwe also improved ftw's stack usage.
1.214 fefe 343: Put movl instead of popl rationale in comment in i386/unified.S since
344: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 345: I discovered __attribute__((malloc)) and started using it. For gcc 3,
346: it improves the optimizer when functions return malloced pointers.
1.216 fefe 347: Steven Rostedt pointed out that my setvbuf was broken with regard to
348: size==0 and sent a patch to fix it.
1.218 fefe 349: Thomas Ogrisegg made setenv smaller.
1.220 olaf 350: Olaf: implemented the parisc clone and an atomic testandset, modified the
351: libpthread to respect the parisc UPgrowing stack. still non functional,
352: because the unified syscall uses errno :(
1.221 fefe 353: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 354: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
355: don't write anything which was no longer the case. It also
356: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 357: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 358:
1.193 fefe 359: 0.13:
1.194 fefe 360: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 361: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 362: Olaf: port to S/390!
1.196 leitner 363: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 364: res_query did not initialize last
1.199 fefe 365: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 366: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 367: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 368: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 369: rewrote __dtostr (it also has one more argument now)
1.205 fefe 370: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 371: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
372: fix strncat for the case where n == 0 (security implications?)
373: fix bsearch (it didn't find the very last element in the array, same
374: bug in both the C and the i386 assembly version).
1.205 fefe 375: fixed FNM_PATHNAME in fnmatch
1.204 fefe 376: fix brk (the syscall was documented incorrectly in the Linux man page)
377: Thanks, Thomas Ogrisegg!
1.205 fefe 378: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 379: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 380: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 381:
1.164 fefe 382: 0.12:
383: more contributions from Frank Klemm.
1.165 fefe 384: iconv can now do UCS-2, too.
1.167 fefe 385: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 386: Lots of bug fixes, and several more i386 specific versions of common
387: routines to make them smaller.
1.168 fefe 388: add memmem (a GNU extension that looks useful)
1.170 fefe 389: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 390: add pivot_root syscall, %n for *scanf.
1.169 fefe 391: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 392: add Frank Klemm's optimized md5
1.172 fefe 393: add -Os option to diet (see diet.1).
1.173 fefe 394: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 395: add 32-bit uid/gid syscalls.
1.175 fefe 396: add rand48 (thanks, Johannes Kloos)
1.176 fefe 397: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 398: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
399: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
400: fix gethostent alias list termination. Major oops.
1.178 fefe 401: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 402: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 403: DNS will now properly signal errors and set h_errno.
404: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 405: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
406: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
407: external reference to a symbol that is only in the diet libc. So,
408: when you accidentally link a diet libc compiled object file against
409: glibc, the linker will barf. This will bloat your object files, but
410: you can remove all the references with "strip -R .note" from
411: the binaries in the end (which you should do anyway).
1.182 fefe 412: fix ARM unified syscall (select did not work).
1.183 fefe 413: add getpwent_r ala glibc and replace getpwent
414: do the same for getgrent and getspent
415: remove entlib (new code is smaller)
1.184 fefe 416: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 417: add getpwnam_r and getpwuid_r
1.186 fefe 418: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 419: Olaf muddled with the dynamic linker. It's a clean-room
420: implementation in the sense that it once worked for Olaf in a clean
421: room ;)
1.188 fefe 422: add if_nameindex and if_freenameindex.
423: fixed arm unified syscalls to work with current binutils (; is no
424: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 425: changed all st_[cma]time types to signed long so comparisons against
426: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 427: fixed two bugs regarding ungetc.
428: add getusershell, setusershell, endusershell (for vs_ftpd)
429: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 430: fixed strftime (was completely hosed)
1.192 fefe 431: added real make install target
1.164 fefe 432:
1.115 fefe 433: 0.11:
434: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 435: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 436: add floor, ceil and memchr prototypes.
437: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 438: cleaner errno vs __errno_location handling
439: add placeholder iconv (iconv_open will always return EINVAL)
440: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
441: initialization of getaddrinfo.
1.119 fefe 442: fix vsnprintf %X (printed lower case)
1.120 fefe 443: I wrote a new getopt. It appears to actually work (it is POSIX
444: compliant, it does not sort argv like the GNU version) and is only
445: a little over 300 bytes on x86.
1.121 fefe 446: Guillaume Cottenceau just wrote me that strncat should be even more
447: broken than it already is: it should append n bytes AND THEN \0!
448: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 449: Fix regexec offset return. autoconf now believes that diet libc has
450: POSIX regular expressions.
1.123 fefe 451: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 452: Fix regular expression match for x* when there is no x at all.
1.125 fefe 453: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 454: Add %h to vsnprintf.
1.127 fefe 455: Add FAQ.
1.128 fefe 456: Make %h work for signed numbers and add %hh to vsnprintf.
457: initgroups ignored the group argument :-(
458: remove printf references and nested functions from glob.
1.129 fefe 459: added an errno in libpthread that will display a prominent linker
460: warning.
1.131 fefe 461: started getting rid of kernel headers. Big task! :-(
1.130 fefe 462: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 463: Olaf: added a lot of code in libdl (not yet complete), changed the
464: startup code to make it work with his libdl and ld.so (needs still work
465: too)
1.134 fefe 466: __dns_readstartfiles only took the first domain or search path.
467: Thanks, Anthony de Boer
1.133 olaf 468: Olaf: added clone and a new unified_syscall for PowerPC
469: also dynlinker is now available (i386 only at this time)
1.135 fefe 470: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 471: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 472: fixed word delimiters in regex (they looked for space, i.e. "," did
473: not work as delimiter)
1.138 fefe 474: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 475: added mkdtemp.
1.142 fefe 476: Uwe Ohse reported all of the following bugs:
477: ttyname should return 0 if !isatty.
478: realpath returns NULL if "." cannot be opened
479: putenv erroneously accepted (and mishandled) entries without "=".
480: popen returned 255 instead of 127 if /bin/sh could not be run.
481: fgetc did not set the internal EOF indicator on EOF.
482: bsearch contained an assumption about integer arithmetic overflow
483: behavior.
484: system did not set SIGCHLD and thus contained a race.
485: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 486: daemon did not check whether open returns an fd below 3
487: perror did not save errno.
1.144 olaf 488: Olaf: Peter Jones reported some problems with perror; strerror had the
489: same problem.
490: Peter also posted a patch to atexit/exit. With some modifications it is
491: now implemented.
1.145 fefe 492: Unbuffered stdio and ungetc can no longer be disabled. I will try to
493: implement part of it using ELF weak symbols.
1.146 fefe 494: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 495: Added overflow handling for strtoul and strtol.
1.149 fefe 496: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
497: it before falling back to DNS if enabled.
1.150 fefe 498: Added a littie backwards compatibility cruft for gpm (man, do these
499: sources stink!)
1.151 fefe 500: Added openpty.
1.152 fefe 501: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 502: Fix fseek return value.
1.155 fefe 503: Add dirname and basename.
1.156 fefe 504: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 505: Fixed getservent (did not allow _ and - in the aliases).
506: Thanks, Oden Eriksson
1.158 fefe 507: Added a float.h so configure believes we have ANSI header files.
508: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 509: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 510: scanf and printf function implementations
1.160 fefe 511: Imported a few more functions and optimizations from Frank Klemm (he
512: also rewrote dtostr to have more precision)
1.161 olaf 513: Olaf: checked in a new sig* function family (based on rt_sig*).
514: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 515: Made rudimentary iconv that can convert back and forth between
516: iso-8859-1, utf-8 and ucs-4 (for debugging).
517: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 518:
1.74 fefe 519: 0.10:
520: update getpagesize.
521: add personality.
1.75 fefe 522: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 523: add putchar (apparently arm-linux-gcc will substitute printf("\n")
524: with putchar('\n') behind your back...?!
1.77 fefe 525: import include/scsi/ from glibc.
1.78 fefe 526: add iopl.
1.80 fefe 527: add execl and sigdelset prototypes.
528: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 529: add RPC headers (no code yet).
1.82 fefe 530: add mlockall, munlockall
1.83 fefe 531: make "diet gcc foo.c" work.
532: added Sun RPC code and removed as many warnings as possible in a
533: heroic act of self-mutilation.
534: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 535: added getpass. mount from util-linux actually compiles now!
536: fix the sig*set routines. mount actually works now *bg*
537: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 538: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 539: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 540: add res_init.
541: add asprintf (ugh, what an ugly function).
1.89 fefe 542: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 543: add ut_name alias to ut_host in struct utmp.
544: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 545: add sysinfo, recvmsg, sendmsg.
1.93 fefe 546: add endmntent, getmntent, setmntent.
1.94 fefe 547: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 548: add setenv.
549: remove __restrict from mntent.h, add __restrict__ removal alias for
550: older gcc versions in sys/cdefs.h.
551: add rlim_t, sig_atomic_t declarations.
552: add sigsetjmp #define for __sigsetjmp (oops).
553: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 554: add a gruesome hack to printf floating point to accept %f and kludge
555: together support for %.2f. Don't look at the code, please!
1.98 fefe 556: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 557: imported fix for entlib by Jeff Garzik.
1.100 fefe 558: add glob implementation from Guillaume Cottenceau (Thanks!!)
559: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 560: add REG_ICASE and word start/end handling to my regular expressions.
561: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 562: wrap getcwd to comply to man page (the syscall returns the number of
563: bytes, not the buffer)
564: add realpath.
1.103 fefe 565: fix vfprintf.
1.104 fefe 566: fix *scanf %s zero termination.
567: add abs, labs, llabs.
1.105 fefe 568: add <sys/io.h>, ioperm syscall.
569: add flock to <sys/file.h>
1.106 fefe 570: fixes to bsearch and the regular expressions.
1.107 fefe 571: add fake herror.
1.108 fefe 572: add scandir and alphasort.
1.109 fefe 573: add killpg
1.110 fefe 574: implemented a gross hack to make libpthread compile when
575: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 576: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 577: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 578: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
579: for sending a patch.
1.114 fefe 580: add getserv*.
581: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
582: "search" from resolv.conf.
1.74 fefe 583:
1.73 fefe 584: 0.9:
1.65 fefe 585: fixed initgroups (oops)
1.66 fefe 586: Cleanup appending file open for stdio (thanks, James Antill)
587: imported vfprintf fix from James Antill.
1.67 fefe 588: add fnmatch
589: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 590: Olaf added character classes to *scanf.
1.69 fefe 591: Put object and library files into a separate directory (bin-$ARCH).
592: Add "cross" make target to make all architectures.
593: Add "diet" program and man page.
1.70 fefe 594: Add getgrnam, getgrgid
1.71 fefe 595: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 596: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 597:
1.64 fefe 598: 0.8:
1.34 fefe 599: vsnprintf(0,...) estimated the length of strings with a padding width
600: incorrectly.
1.35 fefe 601: new reboot() from Olaf.
1.36 fefe 602: added prototypes for getsockopt and setsockopt.
1.39 fefe 603: added experimental sem* and shm*
1.38 fefe 604: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 605: added setvbuf (only changes mode, not buffer)
1.41 fefe 606: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
607: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 608: added qsort() and bsearch(). Benchmark on 1000 random ints:
609: glibc: 679414 cycles qsort and 3352 cycles bsearch
610: diet libc: 300010 cycles qsort, 553 cycles bsearch
611: I have no idea why glibc is so slow.
1.43 fefe 612: added __isnan (references by libm.a from glibc).
613: added popen() and pclose(). Now the diet libc can link slsh (from
614: S-Lang!)
1.44 fefe 615: corrected usleep. It was more of an msleep until now.
1.45 fefe 616: corrected __dtostr (it looped when trying to format "0.0").
617: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 618: added ungetc (does it work?)
1.47 fefe 619: added inet_aton (yuck!)
1.50 fefe 620: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 621: added h_errno and __h_errno_location
622: added inet_ntoa
1.49 fefe 623: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 624: add bcopy, index, rindex macros
625: add isgraph and isxdigit
1.52 fefe 626: add strftime (ugh!!!)
1.53 olaf 627: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 628: Jeff Garzik contributed a spec file. I put it in contrib and hope
629: everbody knows what to do with it...
630: Olaf checked in a ton of libpthread stuff.
1.55 fefe 631: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 632: add large file backwards compatibility support (so gzip will run on
633: kernel 2.2 and 2.0)
1.57 fefe 634: added shutdown
1.58 fefe 635: added nice
636: added pseudo-locale support for is* (they are now weak aliases,
637: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
638: overwrite the default is* functions.
1.59 fefe 639: added liblatin1.a
1.60 fefe 640: added tzfile implementation (does it work for anyone else?)
1.61 fefe 641: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 642: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
643: Thanks!
1.63 fefe 644: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 645:
1.21 fefe 646: 0.7.2:
647: added several prototypes to already implemented functions and
648: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 649: added prototypes for process group and dup syscalls. Thanks to
650: Abraham again. He also contributed an implementation for daemon(),
651: an ugly BSD hack. I decided to diversify the lib/ directory a
652: little and now created a libugly/ directory for stuff like system()
653: and daemon() ;-)
654: added libstdio and moved all that stdio crap from lib/ there. The
655: idea is to start separating now what we will separate for shared
656: libraries anyway.
1.26 fefe 657: optimized x86 unified-syscall by Olaf.
1.27 fefe 658: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
659: limits.h instead)
660: added remove.c and enough cruft to limits.h to make it compile lzo,
661: lzop and bzip2.
1.28 fefe 662: added mktime, asctime_r, asctime and ctime (needed for gzip).
663: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 664: format some day (man tzfile, ugh!) :-(
1.29 fefe 665: added unlink prototype to unistd.h.
666: added gmtime and gmtime_r.
1.31 fefe 667: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 668: removed readdir glibc compatibility cruft.
1.31 fefe 669: removed stat glibc compatibility cruft.
1.32 fefe 670: oops, my fread was broken for pipes.
1.33 fefe 671: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 672:
1.9 fefe 673: 0.7.1:
1.11 fefe 674: optimized away the static arrays from __ltostr and __lltostr.
675: optimized away the static arrays (and more!) from strtoul and strtoull.
676: added system (by Olaf).
1.12 fefe 677: added tolower and toupper
1.13 fefe 678: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 679: added clone for mips (by Olaf).
680: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 681: added pause for all (by Olaf).
1.17 fefe 682: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 683: added isupper and islower.
684: added putc and putchar as macros.
1.17 fefe 685: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
686: insightful discussions and patches I partially used for the last three)
1.18 fefe 687: added getpriority and setpriority (also by Abraham)
1.19 fefe 688: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 689: oi, setjmp and longjmp were broken on other platforms, too!
690: Thanks to Sébastien Côté for reporting this.
1.9 fefe 691:
692: 0.7:
1.6 olaf 693: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 694: Initial dynamic loading glue for i386, also by Olaf.
695: We don't have a dynamic loader yet, so this is not yet usable.
696: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
697: vsprintf, writev, all by Olaf.
1.2 fefe 698: imported readdir fix from Guillaume. Mhh, can the kernel interface
699: really be this broken?
1.3 fefe 700: Found a kludgy way to detect whether the kernel includes define struct
701: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
702: not work for you, please tell me!
1.4 fefe 703: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 704: Fixed stdio line buffering. The code was already there but I forgot
705: to mark stdio and stdout as line buffered. This should really be
706: done dynamically using isatty, though.
1.8 fefe 707: Removed superfluous "if (1)" in execvp.c
1.1 cvs 708:
709: 0.6.14:
710: *scanf did not append the 0 byte for %s.
711: added creat and changed creat to call open directly instead of open64.
712: did for fread what 0.6.10 did for fwrite.
713: repaired buffered stdio a little (line buffering is still not
714: supported).
715: [All of these bugs have been reported by Guillaume. Thanks!]
716: added __pure__ to strchr and strrchr in <string.h>
717:
718: 0.6.13:
719: included COPYING to make clear that the diet libc is covered by the
720: GNU General Public License (and _not_ the LGPL). That means that
721: you need to obtain a license from me if you want to use the diet
722: libc in a proprietary program that you want to distribute.
723: The x86 unified syscall swapped arguments #4 and #5 and noone
724: noticed until now! Thanks to Guillaume Cottenceau for reporting
725: this!
726: The malloc had a subtle bug with small allocations that could cause
727: segfault. Guillaume reported it, Olaf fixed it.
728:
729: 0.6.12:
730: added assert, statfs and fstatfs
731: added include/net/if.h so fget compiles again.
732:
733: 0.6.11:
734: added putenv.
735:
736: 0.6.10:
737: fixed fwrite. It returned the number of bytes written, not the number
738: of records. Thanks to Albert D. Cahalan for pointing this out.
739: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
740: added brk and sbrk. harold@nb.com.sg made me do it.
741:
742: 0.6.9:
743: fixed execvp not to return on ENOENT
744: did for {open|read|close|seek|tell}dir what I did for stat before.
745: The glibc compatibility part is currently non-functional.
746: fixed white space handling in sscanf " (" would not match " (".
747: fixed printf to accept 'l' flag.
748: fixed getpwuid (ignored last line)
749:
750: 0.6.8:
751: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
752: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
753: added strlcpy and strlcat from OpenBSD.
754: added stat64, fstat64 and lstat64.
755: added endian.h and made ending of strlen.c endianness-aware
756: added string routines size tweak to dietfeatures.h. Most of the
757: string routines have been unrolled. This is up to three times as
758: fast but creates up to three times larger code. Now you can disable
759: the unrolling.
760: added sendfile.
761: I also added pread. It works on x86 and sparc but not on ppc and mips.
762: I have no idea what's going on. strace disagrees with the kernel.
763: Can anyone help? I asked the Linux kernel mailing list for help, too.
764: added a few aliases of the type __libc_open for open. nm on
765: libpthreads.so indicates that we will need them.
766:
767: 0.6.7:
768: the sources now compile without warnings with -Wall.
769: printf now prints "(null)" when %s is passed NULL. This can be
770: removed with WANT_NULL_PRINTF in dietfeatures.h
771: added vfprintf, execl, ttyname.
772: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
773: __dietfstat so they can use the normal kernel struct stat.
774: stat, lstat and fstat are now C wrappers that convert to the glibc
775: struct stat. So we can avoid that overhead for programs that use
776: dietlibc headers.
777:
778: 0.6.6:
779: changed the Makefiles so you can now set CFLAGS on the command line
780: added memccmp (analogous to memccpy) and strncmp.
781: Olaf fixed another bug in the sparc unified syscall.
782: Paul Clifford contributed a C version of his strlen.S that is much
783: more efficient than the previous strlen on all platforms! It also
784: looks like technology from Roswell. ;-}
785: added a "real" stdio. Well, almost. Please contribute!
786: added dietfeatures.h so you can remove features you don't need.
787: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
788: stdio now works with simple programs and minigzip from libz.
789: stdio uses some major trickery to avoid linking the stdio, stderr and
790: stdout (and reserving space for them) when they are not used.
791:
792: 0.6.5:
793: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
794: most of them bugs in the new header files, but also missing sigset
795: functions.
796: Paul Clifford contributed an assembly strlen.S for ARM and fixed
797: several bugs.
798: Fixed ppc/setjmp and mips/pipe.
799: Olaf contributed a new sparc unified syscall.
800:
801: 0.6.4:
802: declared is* static inline in getservent.
803: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
804: changed strlen to return 0 when passed NULL.
805: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
806: Scientist who actually implemented this without access to a MIPS
807: box, just from reading the architecture manual. And it worked out
808: of the box.
809: started a set of system includes, mainly so that I can use lcc and
810: my alpha-linux cross compiler (which is unable to cross-compile
811: glibc). diet libc can now be compiled without any include files
812: from a normal libc. The includes do declare more than diet libc
813: currently delivers and they are still far from complete for real
814: applications.
815: I will only add assembly versions that are smaller _and_ faster than
816: the C version. Larger routines are only accepted if they are called
817: very often and are substantially faster.
818: added i386 assembly strchr, which is smaller and faster than the old
819: version. It is, however, larger than the version contributed by
820: proton (thanks, anyway).
821: added i386 strlen (31% faster, 14% smaller)
822: "make t" will now create a map file called "mapfile".
823:
824: 0.6.3:
825: added sys_errlist, strerror and perror
826: added isblank
827: added atol
828:
829: 0.6.2:
830: mmap for ARM didn't compile. Thanks, Paul!
831:
832: 0.6.1:
833: split mmap into the architecture specific subdirectories.
834: getenv now copes with environ==NULL, thanks Paul Clifford.
835: Paul also contributed a smaller ARM startup code.
836:
837: 0.6:
838: strcat returned the wrong result. Thanks, Dietz Pröpper.
839: strtod now understands a negative exponent (oops, thanks Bertram Barth)
840: Port to arm-linux-gnu, but on the Netwinder I use for testing the
841: __dtostr does not work (I have no idea why!)
842: The MIPS port now uses (much smaller) non-PIC code. That means that
843: the applications you link against diet libc also have to be compiled
844: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
845: Thanks to Ralf Bächle for helping me with this!
846: I made subdirectories for the architectures and use VPATH to override
847: VPATH so that make finds the source file automatically. That should
848: simplify the sources greatly.
849: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
850: ARM and MIPS now also have setjmp and longjmp
851: "compile" and "load" are now make targets. Use them for djb programs.
852: added contrib/elftrunc.c which will remove unnecessary ELF headers.
853: Again, contributed from Olaf. Great work!
854:
855: 0.5.12:
856: printf also does signed numbers.
857: If you don't use atexit, dietlibc now does not link exit, only _exit.
858: *printf now correctly returns the number of bytes written.
859: Olaf contributed experimental sscanf and vsscanf implementations.
860: If passed NULL as buffer, snprintf will not write anything but still
861: return the number of bytes it would have written.
862: Initial MIPS port! (Oh, the agony!)
863: No setjmp and longjmp support yet! Please contribute!
864: I even implemented unified syscalls for MIPS. Still, MIPS code is
865: almost twice the size of SPARC code. If anyone knows why: please
866: tell me!
867:
868: 0.5.11:
869: I implemented new unified syscalls for x86, sparc and ppc, this time based
870: on .s files and not .c files, and I moved the syscalls into
871: subdirectores to clean the dietlibc sources up a little.
872: A binary consisting of printf("%s is %d\n","olaf",23) is now
873: 2864 bytes on sparc
874: 2488 bytes on intel
875: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
876: to make a few more applications work.
877: Olaf Dreesen also implemented some unified syscall stuff for x86.
878: He discovered that with our unified syscall interface it actually
879: costs <10 bytes total to make all system calls thread safe!
880: I implemented atexit() (can register up to 4 callbacks).
881: I implemented strtod and __dtostr (the opposite). Now we can add
882: floating point support to vsnprintf and sscanf!
883:
884: 0.5.10:
885: I actually saw that I can not only merge the errno handling code of
886: the system calls on x86, I can also merge the rest (including the
887: arguments) except for setting the system call number. All those
888: system calls are now just a jump to a unified system call handler.
889: I got rid of x86openclose again. The savings are substantial:
890: chown from embutils went from 7664 to 7184 bytes!
891: If I'd move the system call wrappers to assembly language, I could
892: even reduce the alignment (does not matter since it's just a jump
893: anyway) and get rid of the "ret" behind each jump (one byte per
894: system call!)
895:
896: 0.5.9:
897: added memchr, strpbrk, strstr, strtol, isspace (hehe)
898: fixed strdup
899: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
900: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
901: (no signed integers, only strings and unsigned integers (but
902: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
903: that code must be wonderful, I don't understand it at all *bg*)
904: Olaf's printf does understand padding like in "%08d" and "%8d" and
905: automatically pads pointers with '0'.
906: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
907: Thanks to proton for inspiration on this.
908: The new x86 start code also does not reference exit any more, thus saving
909: 64 bytes for executables that don't call exit explicitly.
910: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
911: Moved errno and environ to start.S, saving no byte binary size but
912: speeding up compilation and slightly shortening dietlibc.a ;-)
913: For x86: joined open and close into one assembler file, sharing the
914: errno handling. This is a feasibility test and it actually saves a
915: few bytes. I think I will reimplement the _syscall[1-6] macros on
916: all platforms now to share the errno handling code for them.
917:
918: 0.5.8:
919: fixed strchr to be able to look for 0.
920:
921: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
922: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
923: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
924: contributed by Olaf Dreesen)
925:
926: added execvp, getcwd
927:
928: fixed __xmknod
929:
930: Note: can it be that the ftw interface really is so broken that I
931: cannot implement it without having to implement some searching data
932: structure? I included an experimental ftw implementation that will
933: not follow symlinks.
934:
935: 0.5.7:
936: oops, if_nametoindex was broken!
937:
938: 0.5.6:
939: ported to ppc-linux.
940: fixed i386 sigsetjmp (I mistyped the function name)
941: included sigjmp.c
942:
943: 0.5.5:
944: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
945: actually, it wasn't fork that wasn't working for sparc, it was pipe.
946: I fixed it now.
947: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
948: fixed readdir to use getdents and not the intel inline asm
949:
950: 0.5.4:
951: ported to sparclinux (sparc32 only). Beware: does not work yet.
952: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
953:
954: 0.5.3:
955: added tcsetattr and getenv to compile e3
956:
957: 0.5.2:
958: added vhangup, tcgetattr, isatty and memcmp for fgetty
959: (http://www.fefe.de/fgetty/)
960: added localtime from uC-libc.
961:
962: 0.5.1:
963: stat and friends actually work now. Yuck! Another case of
964: translation between kernel and userland. Why can't the kernel
965: people and the libc people simply agree on a standard?
966: removed many unnecessary includes to speed up compilation.
967: added -fomit-frame-pointer and i386 compilation target to reduce code size.
968: inlined socketcall to reduce code size.
969: "load" and "compile" are examples for djb code.
970:
971: 0.5:
972: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
973: each object file is now treated with "strip -x -R .note -R .comment"
974: split each system call into a separate object file
975: added ntohs, htons, alarm, if_indextoname and if_nametoindex
976:
977: 0.4.1:
978: oops, the strchr implementation was wrong. Thanks Jens Laas!
979:
980: 0.4:
981: copied opendir and friends from uC-libc.
982: added getservent and getservby* in gerservent.c
983:
984: 0.3:
985: remove readdir system call
986: added getdents system call
987: added getpwnam/getpwuid implementation in getpwnam.c
988: added a few string functions (in str*.c)
989:
