1.278 fefe 325: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 326: fix DNS domain search
1.280 fefe 327: i386 memccpy exchanged esi and edi :-( I should do more checks before
328: accepting external code...
1.264 fefe 329:
1.244 fefe 330: 0.16:
331: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 332: Andre found two very embarassing bugs in my four lines of md5 glue.
333: I need to get more sleep.
1.247 fefe 334: Thanks Ogrisegg found that ptrace does not work as documented and
335: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 336: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
337: fix ptrace.h for S/390 and ARM
338: provide a PORTING document so we don't lose track of which file need
339: to be touched to port the diet libc to a new platform.
1.249 fefe 340: remove a few warnings
341: provide a prototype for usleep.
1.250 fefe 342: make __dtostr work on ARM by using long instead of long long.
343: Idea by Dirk Engling.
1.251 fefe 344: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 345: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 346: Kurt Garloff sent in patches to
347: fix struct termios on non-x86 architectures
1.254 fefe 348: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
349: create libcompat.a (and move daemon to it)
1.255 fefe 350: add getdelim and getline
351: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 352: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 353: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 354: Hans Lermen fixed i386/getenv.S
1.259 fefe 355: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 356: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
357: Macodiseas)
1.261 fefe 358: sys/ipc.h now includes sys/types.h
1.262 olaf 359: Olaf: started to make the sparc64 port
1.263 fefe 360: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 361:
1.224 fefe 362: 0.15:
1.225 fefe 363: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 364: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 365: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
366: thread-safe!
1.228 fefe 367: remove vfork and add alarm to dynamic syscalls.
368: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 369: The MD5 code generated unaligned accesses when passed an unaligned
370: pointer on little endian ARM and MIPS.
371: MIPS unified syscall didn't compile anymore.
372: Put up new mipsel target to cross compile for little endian mips.
373: The mips target will again explicitly set endianness to big endian.
374: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 375: Duh, when we removed return0, we broke tzset when the time zone parser
376: was disabled. Uwe Ohse noticed this. Thanks!
377: Fix gethostbyname to match host names case insensitively in /etc/hosts.
378: Oops, this was reported 6 weeks ago but I overlooked the email.
379: Thanks, Denis Rachal!
1.231 fefe 380: vsnprintf's zero termination was broken.
1.233 fefe 381: Uwe Ohse found a few more bugs:
382: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
383: does it correctly.
384: Make inet_aton use strtoul instead of strtol
385: fdopen would close the file descriptor if it could not malloc the
386: buffer.
387: strftime updates.
388: Make _FILE_OFFSET_BITS includes -Wundef clean
389: Andre found a typo in endian.h for big endian mips
1.234 fefe 390: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 391: strstr(whatever,"") returned NULL, not whatever. Found by a new test
392: suite entry for strstr that I wrote.
1.245 fefe 393: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 394: add <asm/sigcontext.h> for profiling support.
395: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 396: an i386 assembler getenv implementation (roughly half the size)
397: add grantpt, ptsname, unlockpt
1.236 fefe 398: add a getenv test suite entry.
1.238 fefe 399: Andre contributed an ARM assembler md5 implementation and he fixed mmap
400: on ARM.
401: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 402: getservent_r did not parse lines without aliases. Thanks, Jaroslav
403: Macodiseas!
1.240 fefe 404: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 405: removed annoying -Wconversion gcc switch
1.242 fefe 406: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 407: Kurt Garloff sent these diffs:
408: add fdatasync (and make it a pthread cancellation point)
409: numerous alpha issues, like using .quad instead of .long for
410: offsets, change strip to -strip in Makefile (so a failing strip does
411: not abort the make), try to be more friendly to the gcc 2.96 that
412: SuSE 7.1 AXP ships with.
1.224 fefe 413:
1.209 fefe 414: 0.14:
1.224 fefe 415: fix brk again (missing __brk, trivial oversight)
1.210 fefe 416: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
417: Thomas Ogrisegg!
1.211 fefe 418: Thomas also contributed a PA-RISC port including testandset, so
419: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 420: made the fake locale more believable.
421: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 422: moved _exit into the unified syscall on x86.
1.214 fefe 423: Uwe Ohse found many more bugs:
424: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
425: liblatin1 was more or less completely broken if you gave it chars as
426: arguments, not ints (signedness). execvp had a buffer overflow in
427: case a PATH element exceeded PATH_MAX, but it's not a security
428: problem since setuid programs need to set their path to some known
429: value anyway.
1.219 fefe 430: hasmntopt did not work with foo=bar style options
1.217 fefe 431: Uwe also improved ftw's stack usage.
1.214 fefe 432: Put movl instead of popl rationale in comment in i386/unified.S since
433: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 434: I discovered __attribute__((malloc)) and started using it. For gcc 3,
435: it improves the optimizer when functions return malloced pointers.
1.216 fefe 436: Steven Rostedt pointed out that my setvbuf was broken with regard to
437: size==0 and sent a patch to fix it.
1.218 fefe 438: Thomas Ogrisegg made setenv smaller.
1.220 olaf 439: Olaf: implemented the parisc clone and an atomic testandset, modified the
440: libpthread to respect the parisc UPgrowing stack. still non functional,
441: because the unified syscall uses errno :(
1.221 fefe 442: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 443: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
444: don't write anything which was no longer the case. It also
445: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 446: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 447:
1.193 fefe 448: 0.13:
1.194 fefe 449: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 450: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 451: Olaf: port to S/390!
1.463 leitner 452: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 453: res_query did not initialize last
1.199 fefe 454: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 455: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 456: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 457: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 458: rewrote __dtostr (it also has one more argument now)
1.205 fefe 459: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 460: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
461: fix strncat for the case where n == 0 (security implications?)
462: fix bsearch (it didn't find the very last element in the array, same
463: bug in both the C and the i386 assembly version).
1.205 fefe 464: fixed FNM_PATHNAME in fnmatch
1.204 fefe 465: fix brk (the syscall was documented incorrectly in the Linux man page)
466: Thanks, Thomas Ogrisegg!
1.205 fefe 467: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 468: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 469: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 470:
1.164 fefe 471: 0.12:
472: more contributions from Frank Klemm.
1.165 fefe 473: iconv can now do UCS-2, too.
1.167 fefe 474: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 475: Lots of bug fixes, and several more i386 specific versions of common
476: routines to make them smaller.
1.168 fefe 477: add memmem (a GNU extension that looks useful)
1.170 fefe 478: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 479: add pivot_root syscall, %n for *scanf.
1.169 fefe 480: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 481: add Frank Klemm's optimized md5
1.172 fefe 482: add -Os option to diet (see diet.1).
1.173 fefe 483: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 484: add 32-bit uid/gid syscalls.
1.175 fefe 485: add rand48 (thanks, Johannes Kloos)
1.176 fefe 486: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 487: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
488: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
489: fix gethostent alias list termination. Major oops.
1.178 fefe 490: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 491: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 492: DNS will now properly signal errors and set h_errno.
493: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 494: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
495: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
496: external reference to a symbol that is only in the diet libc. So,
497: when you accidentally link a diet libc compiled object file against
498: glibc, the linker will barf. This will bloat your object files, but
499: you can remove all the references with "strip -R .note" from
500: the binaries in the end (which you should do anyway).
1.182 fefe 501: fix ARM unified syscall (select did not work).
1.183 fefe 502: add getpwent_r ala glibc and replace getpwent
503: do the same for getgrent and getspent
504: remove entlib (new code is smaller)
1.184 fefe 505: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 506: add getpwnam_r and getpwuid_r
1.186 fefe 507: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 508: Olaf muddled with the dynamic linker. It's a clean-room
509: implementation in the sense that it once worked for Olaf in a clean
510: room ;)
1.188 fefe 511: add if_nameindex and if_freenameindex.
512: fixed arm unified syscalls to work with current binutils (; is no
513: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 514: changed all st_[cma]time types to signed long so comparisons against
515: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 516: fixed two bugs regarding ungetc.
517: add getusershell, setusershell, endusershell (for vs_ftpd)
518: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 519: fixed strftime (was completely hosed)
1.192 fefe 520: added real make install target
1.164 fefe 521:
1.115 fefe 522: 0.11:
523: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 524: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 525: add floor, ceil and memchr prototypes.
526: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 527: cleaner errno vs __errno_location handling
528: add placeholder iconv (iconv_open will always return EINVAL)
529: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
530: initialization of getaddrinfo.
1.119 fefe 531: fix vsnprintf %X (printed lower case)
1.120 fefe 532: I wrote a new getopt. It appears to actually work (it is POSIX
533: compliant, it does not sort argv like the GNU version) and is only
534: a little over 300 bytes on x86.
1.121 fefe 535: Guillaume Cottenceau just wrote me that strncat should be even more
536: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 537: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 538: Fix regexec offset return. autoconf now believes that diet libc has
539: POSIX regular expressions.
1.123 fefe 540: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 541: Fix regular expression match for x* when there is no x at all.
1.125 fefe 542: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 543: Add %h to vsnprintf.
1.127 fefe 544: Add FAQ.
1.128 fefe 545: Make %h work for signed numbers and add %hh to vsnprintf.
546: initgroups ignored the group argument :-(
547: remove printf references and nested functions from glob.
1.129 fefe 548: added an errno in libpthread that will display a prominent linker
549: warning.
1.131 fefe 550: started getting rid of kernel headers. Big task! :-(
1.130 fefe 551: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 552: Olaf: added a lot of code in libdl (not yet complete), changed the
553: startup code to make it work with his libdl and ld.so (needs still work
554: too)
1.134 fefe 555: __dns_readstartfiles only took the first domain or search path.
556: Thanks, Anthony de Boer
1.133 olaf 557: Olaf: added clone and a new unified_syscall for PowerPC
558: also dynlinker is now available (i386 only at this time)
1.135 fefe 559: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 560: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 561: fixed word delimiters in regex (they looked for space, i.e. "," did
562: not work as delimiter)
1.138 fefe 563: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 564: added mkdtemp.
1.142 fefe 565: Uwe Ohse reported all of the following bugs:
566: ttyname should return 0 if !isatty.
567: realpath returns NULL if "." cannot be opened
568: putenv erroneously accepted (and mishandled) entries without "=".
569: popen returned 255 instead of 127 if /bin/sh could not be run.
570: fgetc did not set the internal EOF indicator on EOF.
571: bsearch contained an assumption about integer arithmetic overflow
572: behavior.
573: system did not set SIGCHLD and thus contained a race.
574: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 575: daemon did not check whether open returns an fd below 3
576: perror did not save errno.
1.144 olaf 577: Olaf: Peter Jones reported some problems with perror; strerror had the
578: same problem.
579: Peter also posted a patch to atexit/exit. With some modifications it is
580: now implemented.
1.145 fefe 581: Unbuffered stdio and ungetc can no longer be disabled. I will try to
582: implement part of it using ELF weak symbols.
1.146 fefe 583: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 584: Added overflow handling for strtoul and strtol.
1.149 fefe 585: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
586: it before falling back to DNS if enabled.
1.150 fefe 587: Added a littie backwards compatibility cruft for gpm (man, do these
588: sources stink!)
1.151 fefe 589: Added openpty.
1.152 fefe 590: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 591: Fix fseek return value.
1.155 fefe 592: Add dirname and basename.
1.156 fefe 593: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 594: Fixed getservent (did not allow _ and - in the aliases).
595: Thanks, Oden Eriksson
1.158 fefe 596: Added a float.h so configure believes we have ANSI header files.
597: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 598: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 599: scanf and printf function implementations
1.160 fefe 600: Imported a few more functions and optimizations from Frank Klemm (he
601: also rewrote dtostr to have more precision)
1.161 olaf 602: Olaf: checked in a new sig* function family (based on rt_sig*).
603: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 604: Made rudimentary iconv that can convert back and forth between
605: iso-8859-1, utf-8 and ucs-4 (for debugging).
606: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 607:
1.74 fefe 608: 0.10:
609: update getpagesize.
610: add personality.
1.75 fefe 611: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 612: add putchar (apparently arm-linux-gcc will substitute printf("\n")
613: with putchar('\n') behind your back...?!
1.77 fefe 614: import include/scsi/ from glibc.
1.78 fefe 615: add iopl.
1.80 fefe 616: add execl and sigdelset prototypes.
617: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 618: add RPC headers (no code yet).
1.82 fefe 619: add mlockall, munlockall
1.83 fefe 620: make "diet gcc foo.c" work.
621: added Sun RPC code and removed as many warnings as possible in a
622: heroic act of self-mutilation.
623: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 624: added getpass. mount from util-linux actually compiles now!
625: fix the sig*set routines. mount actually works now *bg*
626: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 627: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 628: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 629: add res_init.
630: add asprintf (ugh, what an ugly function).
1.89 fefe 631: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 632: add ut_name alias to ut_host in struct utmp.
633: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 634: add sysinfo, recvmsg, sendmsg.
1.93 fefe 635: add endmntent, getmntent, setmntent.
1.94 fefe 636: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 637: add setenv.
638: remove __restrict from mntent.h, add __restrict__ removal alias for
639: older gcc versions in sys/cdefs.h.
640: add rlim_t, sig_atomic_t declarations.
641: add sigsetjmp #define for __sigsetjmp (oops).
642: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 643: add a gruesome hack to printf floating point to accept %f and kludge
644: together support for %.2f. Don't look at the code, please!
1.98 fefe 645: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 646: imported fix for entlib by Jeff Garzik.
1.100 fefe 647: add glob implementation from Guillaume Cottenceau (Thanks!!)
648: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 649: add REG_ICASE and word start/end handling to my regular expressions.
650: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 651: wrap getcwd to comply to man page (the syscall returns the number of
652: bytes, not the buffer)
653: add realpath.
1.103 fefe 654: fix vfprintf.
1.104 fefe 655: fix *scanf %s zero termination.
656: add abs, labs, llabs.
1.105 fefe 657: add <sys/io.h>, ioperm syscall.
658: add flock to <sys/file.h>
1.106 fefe 659: fixes to bsearch and the regular expressions.
1.107 fefe 660: add fake herror.
1.108 fefe 661: add scandir and alphasort.
1.109 fefe 662: add killpg
1.110 fefe 663: implemented a gross hack to make libpthread compile when
664: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 665: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 666: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 667: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
668: for sending a patch.
1.114 fefe 669: add getserv*.
670: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
671: "search" from resolv.conf.
1.74 fefe 672:
1.73 fefe 673: 0.9:
1.65 fefe 674: fixed initgroups (oops)
1.66 fefe 675: Cleanup appending file open for stdio (thanks, James Antill)
676: imported vfprintf fix from James Antill.
1.67 fefe 677: add fnmatch
678: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 679: Olaf added character classes to *scanf.
1.69 fefe 680: Put object and library files into a separate directory (bin-$ARCH).
681: Add "cross" make target to make all architectures.
682: Add "diet" program and man page.
1.70 fefe 683: Add getgrnam, getgrgid
1.71 fefe 684: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 685: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 686:
1.64 fefe 687: 0.8:
1.34 fefe 688: vsnprintf(0,...) estimated the length of strings with a padding width
689: incorrectly.
1.35 fefe 690: new reboot() from Olaf.
1.36 fefe 691: added prototypes for getsockopt and setsockopt.
1.39 fefe 692: added experimental sem* and shm*
1.38 fefe 693: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 694: added setvbuf (only changes mode, not buffer)
1.41 fefe 695: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
696: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 697: added qsort() and bsearch(). Benchmark on 1000 random ints:
698: glibc: 679414 cycles qsort and 3352 cycles bsearch
699: diet libc: 300010 cycles qsort, 553 cycles bsearch
700: I have no idea why glibc is so slow.
1.43 fefe 701: added __isnan (references by libm.a from glibc).
702: added popen() and pclose(). Now the diet libc can link slsh (from
703: S-Lang!)
1.44 fefe 704: corrected usleep. It was more of an msleep until now.
1.45 fefe 705: corrected __dtostr (it looped when trying to format "0.0").
706: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 707: added ungetc (does it work?)
1.47 fefe 708: added inet_aton (yuck!)
1.50 fefe 709: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 710: added h_errno and __h_errno_location
711: added inet_ntoa
1.49 fefe 712: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 713: add bcopy, index, rindex macros
714: add isgraph and isxdigit
1.52 fefe 715: add strftime (ugh!!!)
1.53 olaf 716: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 717: Jeff Garzik contributed a spec file. I put it in contrib and hope
718: everbody knows what to do with it...
719: Olaf checked in a ton of libpthread stuff.
1.55 fefe 720: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 721: add large file backwards compatibility support (so gzip will run on
722: kernel 2.2 and 2.0)
1.57 fefe 723: added shutdown
1.58 fefe 724: added nice
725: added pseudo-locale support for is* (they are now weak aliases,
726: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
727: overwrite the default is* functions.
1.59 fefe 728: added liblatin1.a
1.60 fefe 729: added tzfile implementation (does it work for anyone else?)
1.61 fefe 730: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 731: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
732: Thanks!
1.63 fefe 733: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 734:
1.21 fefe 735: 0.7.2:
736: added several prototypes to already implemented functions and
737: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 738: added prototypes for process group and dup syscalls. Thanks to
739: Abraham again. He also contributed an implementation for daemon(),
740: an ugly BSD hack. I decided to diversify the lib/ directory a
741: little and now created a libugly/ directory for stuff like system()
742: and daemon() ;-)
743: added libstdio and moved all that stdio crap from lib/ there. The
744: idea is to start separating now what we will separate for shared
745: libraries anyway.
1.26 fefe 746: optimized x86 unified-syscall by Olaf.
1.27 fefe 747: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
748: limits.h instead)
749: added remove.c and enough cruft to limits.h to make it compile lzo,
750: lzop and bzip2.
1.28 fefe 751: added mktime, asctime_r, asctime and ctime (needed for gzip).
752: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 753: format some day (man tzfile, ugh!) :-(
1.29 fefe 754: added unlink prototype to unistd.h.
755: added gmtime and gmtime_r.
1.31 fefe 756: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 757: removed readdir glibc compatibility cruft.
1.31 fefe 758: removed stat glibc compatibility cruft.
1.32 fefe 759: oops, my fread was broken for pipes.
1.33 fefe 760: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 761:
1.9 fefe 762: 0.7.1:
1.11 fefe 763: optimized away the static arrays from __ltostr and __lltostr.
764: optimized away the static arrays (and more!) from strtoul and strtoull.
765: added system (by Olaf).
1.12 fefe 766: added tolower and toupper
1.13 fefe 767: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 768: added clone for mips (by Olaf).
769: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 770: added pause for all (by Olaf).
1.17 fefe 771: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 772: added isupper and islower.
773: added putc and putchar as macros.
1.17 fefe 774: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
775: insightful discussions and patches I partially used for the last three)
1.18 fefe 776: added getpriority and setpriority (also by Abraham)
1.19 fefe 777: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 778: oi, setjmp and longjmp were broken on other platforms, too!
779: Thanks to Sébastien Côté for reporting this.
1.9 fefe 780:
781: 0.7:
1.6 olaf 782: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 783: Initial dynamic loading glue for i386, also by Olaf.
784: We don't have a dynamic loader yet, so this is not yet usable.
785: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
786: vsprintf, writev, all by Olaf.
1.2 fefe 787: imported readdir fix from Guillaume. Mhh, can the kernel interface
788: really be this broken?
1.3 fefe 789: Found a kludgy way to detect whether the kernel includes define struct
790: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
791: not work for you, please tell me!
1.4 fefe 792: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 793: Fixed stdio line buffering. The code was already there but I forgot
794: to mark stdio and stdout as line buffered. This should really be
795: done dynamically using isatty, though.
1.8 fefe 796: Removed superfluous "if (1)" in execvp.c
1.1 cvs 797:
798: 0.6.14:
799: *scanf did not append the 0 byte for %s.
800: added creat and changed creat to call open directly instead of open64.
801: did for fread what 0.6.10 did for fwrite.
802: repaired buffered stdio a little (line buffering is still not
803: supported).
804: [All of these bugs have been reported by Guillaume. Thanks!]
805: added __pure__ to strchr and strrchr in <string.h>
806:
807: 0.6.13:
808: included COPYING to make clear that the diet libc is covered by the
809: GNU General Public License (and _not_ the LGPL). That means that
810: you need to obtain a license from me if you want to use the diet
811: libc in a proprietary program that you want to distribute.
812: The x86 unified syscall swapped arguments #4 and #5 and noone
813: noticed until now! Thanks to Guillaume Cottenceau for reporting
814: this!
815: The malloc had a subtle bug with small allocations that could cause
816: segfault. Guillaume reported it, Olaf fixed it.
817:
818: 0.6.12:
819: added assert, statfs and fstatfs
820: added include/net/if.h so fget compiles again.
821:
822: 0.6.11:
823: added putenv.
824:
825: 0.6.10:
826: fixed fwrite. It returned the number of bytes written, not the number
827: of records. Thanks to Albert D. Cahalan for pointing this out.
828: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
829: added brk and sbrk. harold@nb.com.sg made me do it.
830:
831: 0.6.9:
832: fixed execvp not to return on ENOENT
833: did for {open|read|close|seek|tell}dir what I did for stat before.
834: The glibc compatibility part is currently non-functional.
835: fixed white space handling in sscanf " (" would not match " (".
836: fixed printf to accept 'l' flag.
837: fixed getpwuid (ignored last line)
838:
839: 0.6.8:
840: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
841: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
842: added strlcpy and strlcat from OpenBSD.
843: added stat64, fstat64 and lstat64.
844: added endian.h and made ending of strlen.c endianness-aware
845: added string routines size tweak to dietfeatures.h. Most of the
846: string routines have been unrolled. This is up to three times as
847: fast but creates up to three times larger code. Now you can disable
848: the unrolling.
849: added sendfile.
850: I also added pread. It works on x86 and sparc but not on ppc and mips.
851: I have no idea what's going on. strace disagrees with the kernel.
852: Can anyone help? I asked the Linux kernel mailing list for help, too.
853: added a few aliases of the type __libc_open for open. nm on
854: libpthreads.so indicates that we will need them.
855:
856: 0.6.7:
857: the sources now compile without warnings with -Wall.
858: printf now prints "(null)" when %s is passed NULL. This can be
859: removed with WANT_NULL_PRINTF in dietfeatures.h
860: added vfprintf, execl, ttyname.
861: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
862: __dietfstat so they can use the normal kernel struct stat.
863: stat, lstat and fstat are now C wrappers that convert to the glibc
864: struct stat. So we can avoid that overhead for programs that use
865: dietlibc headers.
866:
867: 0.6.6:
868: changed the Makefiles so you can now set CFLAGS on the command line
869: added memccmp (analogous to memccpy) and strncmp.
870: Olaf fixed another bug in the sparc unified syscall.
871: Paul Clifford contributed a C version of his strlen.S that is much
872: more efficient than the previous strlen on all platforms! It also
873: looks like technology from Roswell. ;-}
874: added a "real" stdio. Well, almost. Please contribute!
875: added dietfeatures.h so you can remove features you don't need.
876: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
877: stdio now works with simple programs and minigzip from libz.
878: stdio uses some major trickery to avoid linking the stdio, stderr and
879: stdout (and reserving space for them) when they are not used.
880:
881: 0.6.5:
882: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
883: most of them bugs in the new header files, but also missing sigset
884: functions.
885: Paul Clifford contributed an assembly strlen.S for ARM and fixed
886: several bugs.
887: Fixed ppc/setjmp and mips/pipe.
888: Olaf contributed a new sparc unified syscall.
889:
890: 0.6.4:
891: declared is* static inline in getservent.
892: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
893: changed strlen to return 0 when passed NULL.
894: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
895: Scientist who actually implemented this without access to a MIPS
896: box, just from reading the architecture manual. And it worked out
897: of the box.
898: started a set of system includes, mainly so that I can use lcc and
899: my alpha-linux cross compiler (which is unable to cross-compile
900: glibc). diet libc can now be compiled without any include files
901: from a normal libc. The includes do declare more than diet libc
902: currently delivers and they are still far from complete for real
903: applications.
904: I will only add assembly versions that are smaller _and_ faster than
905: the C version. Larger routines are only accepted if they are called
906: very often and are substantially faster.
907: added i386 assembly strchr, which is smaller and faster than the old
908: version. It is, however, larger than the version contributed by
909: proton (thanks, anyway).
910: added i386 strlen (31% faster, 14% smaller)
911: "make t" will now create a map file called "mapfile".
912:
913: 0.6.3:
914: added sys_errlist, strerror and perror
915: added isblank
916: added atol
917:
918: 0.6.2:
919: mmap for ARM didn't compile. Thanks, Paul!
920:
921: 0.6.1:
922: split mmap into the architecture specific subdirectories.
923: getenv now copes with environ==NULL, thanks Paul Clifford.
924: Paul also contributed a smaller ARM startup code.
925:
926: 0.6:
927: strcat returned the wrong result. Thanks, Dietz Pröpper.
928: strtod now understands a negative exponent (oops, thanks Bertram Barth)
929: Port to arm-linux-gnu, but on the Netwinder I use for testing the
930: __dtostr does not work (I have no idea why!)
931: The MIPS port now uses (much smaller) non-PIC code. That means that
932: the applications you link against diet libc also have to be compiled
933: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
934: Thanks to Ralf Bächle for helping me with this!
935: I made subdirectories for the architectures and use VPATH to override
936: VPATH so that make finds the source file automatically. That should
937: simplify the sources greatly.
938: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
939: ARM and MIPS now also have setjmp and longjmp
940: "compile" and "load" are now make targets. Use them for djb programs.
941: added contrib/elftrunc.c which will remove unnecessary ELF headers.
942: Again, contributed from Olaf. Great work!
943:
944: 0.5.12:
945: printf also does signed numbers.
946: If you don't use atexit, dietlibc now does not link exit, only _exit.
947: *printf now correctly returns the number of bytes written.
948: Olaf contributed experimental sscanf and vsscanf implementations.
949: If passed NULL as buffer, snprintf will not write anything but still
950: return the number of bytes it would have written.
951: Initial MIPS port! (Oh, the agony!)
952: No setjmp and longjmp support yet! Please contribute!
953: I even implemented unified syscalls for MIPS. Still, MIPS code is
954: almost twice the size of SPARC code. If anyone knows why: please
955: tell me!
956:
957: 0.5.11:
958: I implemented new unified syscalls for x86, sparc and ppc, this time based
959: on .s files and not .c files, and I moved the syscalls into
960: subdirectores to clean the dietlibc sources up a little.
961: A binary consisting of printf("%s is %d\n","olaf",23) is now
962: 2864 bytes on sparc
963: 2488 bytes on intel
964: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
965: to make a few more applications work.
966: Olaf Dreesen also implemented some unified syscall stuff for x86.
967: He discovered that with our unified syscall interface it actually
968: costs <10 bytes total to make all system calls thread safe!
969: I implemented atexit() (can register up to 4 callbacks).
970: I implemented strtod and __dtostr (the opposite). Now we can add
971: floating point support to vsnprintf and sscanf!
972:
973: 0.5.10:
974: I actually saw that I can not only merge the errno handling code of
975: the system calls on x86, I can also merge the rest (including the
976: arguments) except for setting the system call number. All those
977: system calls are now just a jump to a unified system call handler.
978: I got rid of x86openclose again. The savings are substantial:
979: chown from embutils went from 7664 to 7184 bytes!
980: If I'd move the system call wrappers to assembly language, I could
981: even reduce the alignment (does not matter since it's just a jump
982: anyway) and get rid of the "ret" behind each jump (one byte per
983: system call!)
984:
985: 0.5.9:
986: added memchr, strpbrk, strstr, strtol, isspace (hehe)
987: fixed strdup
988: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
989: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
990: (no signed integers, only strings and unsigned integers (but
991: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
992: that code must be wonderful, I don't understand it at all *bg*)
993: Olaf's printf does understand padding like in "%08d" and "%8d" and
994: automatically pads pointers with '0'.
995: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
996: Thanks to proton for inspiration on this.
997: The new x86 start code also does not reference exit any more, thus saving
998: 64 bytes for executables that don't call exit explicitly.
999: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
1000: Moved errno and environ to start.S, saving no byte binary size but
1001: speeding up compilation and slightly shortening dietlibc.a ;-)
1002: For x86: joined open and close into one assembler file, sharing the
1003: errno handling. This is a feasibility test and it actually saves a
1004: few bytes. I think I will reimplement the _syscall[1-6] macros on
1005: all platforms now to share the errno handling code for them.
1006:
1007: 0.5.8:
1008: fixed strchr to be able to look for 0.
1009:
1010: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
1011: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
1012: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
1013: contributed by Olaf Dreesen)
1014:
1015: added execvp, getcwd
1016:
1017: fixed __xmknod
1018:
1019: Note: can it be that the ftw interface really is so broken that I
1020: cannot implement it without having to implement some searching data
1021: structure? I included an experimental ftw implementation that will
1022: not follow symlinks.
1023:
1024: 0.5.7:
1025: oops, if_nametoindex was broken!
1026:
1027: 0.5.6:
1028: ported to ppc-linux.
1029: fixed i386 sigsetjmp (I mistyped the function name)
1030: included sigjmp.c
1031:
1032: 0.5.5:
1033: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1034: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1035: I fixed it now.
1036: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1037: fixed readdir to use getdents and not the intel inline asm
1038:
1039: 0.5.4:
1040: ported to sparclinux (sparc32 only). Beware: does not work yet.
1041: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1042:
1043: 0.5.3:
1044: added tcsetattr and getenv to compile e3
1045:
1046: 0.5.2:
1047: added vhangup, tcgetattr, isatty and memcmp for fgetty
1048: (http://www.fefe.de/fgetty/)
1049: added localtime from uC-libc.
1050:
1051: 0.5.1:
1052: stat and friends actually work now. Yuck! Another case of
1053: translation between kernel and userland. Why can't the kernel
1054: people and the libc people simply agree on a standard?
1055: removed many unnecessary includes to speed up compilation.
1056: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1057: inlined socketcall to reduce code size.
1058: "load" and "compile" are examples for djb code.
1059:
1060: 0.5:
1061: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1062: each object file is now treated with "strip -x -R .note -R .comment"
1063: split each system call into a separate object file
1064: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1065:
1066: 0.4.1:
1067: oops, the strchr implementation was wrong. Thanks Jens Laas!
1068:
1069: 0.4:
1070: copied opendir and friends from uC-libc.
1071: added getservent and getservby* in gerservent.c
1072:
1073: 0.3:
1074: remove readdir system call
1075: added getdents system call
1076: added getpwnam/getpwuid implementation in getpwnam.c
1077: added a few string functions (in str*.c)
1078:
