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