325: to be touched to port the diet libc to a new platform.
1.249 fefe 326: remove a few warnings
327: provide a prototype for usleep.
1.250 fefe 328: make __dtostr work on ARM by using long instead of long long.
329: Idea by Dirk Engling.
1.251 fefe 330: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 331: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 332: Kurt Garloff sent in patches to
333: fix struct termios on non-x86 architectures
1.254 fefe 334: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
335: create libcompat.a (and move daemon to it)
1.255 fefe 336: add getdelim and getline
337: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 338: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 339: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 340: Hans Lermen fixed i386/getenv.S
1.259 fefe 341: diet -Os no longer discards -fpic and -fno-pic
1.260 fefe 342: fix i386 rand/random to use correct RAND_MAX (thanks, Jaroslav
343: Macodiseas)
1.261 fefe 344: sys/ipc.h now includes sys/types.h
1.262 olaf 345: Olaf: started to make the sparc64 port
1.263 fefe 346: scandir should not sort if compar() is NULL (reported by Andrea Marrosu)
1.244 fefe 347:
1.224 fefe 348: 0.15:
1.225 fefe 349: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 350: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 351: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
352: thread-safe!
1.228 fefe 353: remove vfork and add alarm to dynamic syscalls.
354: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 355: The MD5 code generated unaligned accesses when passed an unaligned
356: pointer on little endian ARM and MIPS.
357: MIPS unified syscall didn't compile anymore.
358: Put up new mipsel target to cross compile for little endian mips.
359: The mips target will again explicitly set endianness to big endian.
360: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 361: Duh, when we removed return0, we broke tzset when the time zone parser
362: was disabled. Uwe Ohse noticed this. Thanks!
363: Fix gethostbyname to match host names case insensitively in /etc/hosts.
364: Oops, this was reported 6 weeks ago but I overlooked the email.
365: Thanks, Denis Rachal!
1.231 fefe 366: vsnprintf's zero termination was broken.
1.233 fefe 367: Uwe Ohse found a few more bugs:
368: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
369: does it correctly.
370: Make inet_aton use strtoul instead of strtol
371: fdopen would close the file descriptor if it could not malloc the
372: buffer.
373: strftime updates.
374: Make _FILE_OFFSET_BITS includes -Wundef clean
375: Andre found a typo in endian.h for big endian mips
1.234 fefe 376: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 377: strstr(whatever,"") returned NULL, not whatever. Found by a new test
378: suite entry for strstr that I wrote.
1.245 fefe 379: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 380: add <asm/sigcontext.h> for profiling support.
381: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 382: an i386 assembler getenv implementation (roughly half the size)
383: add grantpt, ptsname, unlockpt
1.236 fefe 384: add a getenv test suite entry.
1.238 fefe 385: Andre contributed an ARM assembler md5 implementation and he fixed mmap
386: on ARM.
387: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 388: getservent_r did not parse lines without aliases. Thanks, Jaroslav
389: Macodiseas!
1.240 fefe 390: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 391: removed annoying -Wconversion gcc switch
1.242 fefe 392: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 393: Kurt Garloff sent these diffs:
394: add fdatasync (and make it a pthread cancellation point)
395: numerous alpha issues, like using .quad instead of .long for
396: offsets, change strip to -strip in Makefile (so a failing strip does
397: not abort the make), try to be more friendly to the gcc 2.96 that
398: SuSE 7.1 AXP ships with.
1.224 fefe 399:
1.209 fefe 400: 0.14:
1.224 fefe 401: fix brk again (missing __brk, trivial oversight)
1.210 fefe 402: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
403: Thomas Ogrisegg!
1.211 fefe 404: Thomas also contributed a PA-RISC port including testandset, so
405: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 406: made the fake locale more believable.
407: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 408: moved _exit into the unified syscall on x86.
1.214 fefe 409: Uwe Ohse found many more bugs:
410: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
411: liblatin1 was more or less completely broken if you gave it chars as
412: arguments, not ints (signedness). execvp had a buffer overflow in
413: case a PATH element exceeded PATH_MAX, but it's not a security
414: problem since setuid programs need to set their path to some known
415: value anyway.
1.219 fefe 416: hasmntopt did not work with foo=bar style options
1.217 fefe 417: Uwe also improved ftw's stack usage.
1.214 fefe 418: Put movl instead of popl rationale in comment in i386/unified.S since
419: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 420: I discovered __attribute__((malloc)) and started using it. For gcc 3,
421: it improves the optimizer when functions return malloced pointers.
1.216 fefe 422: Steven Rostedt pointed out that my setvbuf was broken with regard to
423: size==0 and sent a patch to fix it.
1.218 fefe 424: Thomas Ogrisegg made setenv smaller.
1.220 olaf 425: Olaf: implemented the parisc clone and an atomic testandset, modified the
426: libpthread to respect the parisc UPgrowing stack. still non functional,
427: because the unified syscall uses errno :(
1.221 fefe 428: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 429: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
430: don't write anything which was no longer the case. It also
431: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 432: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 433:
1.193 fefe 434: 0.13:
1.194 fefe 435: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 436: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 437: Olaf: port to S/390!
1.463 leitner 438: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 439: res_query did not initialize last
1.199 fefe 440: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 441: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 442: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 443: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 444: rewrote __dtostr (it also has one more argument now)
1.205 fefe 445: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 446: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
447: fix strncat for the case where n == 0 (security implications?)
448: fix bsearch (it didn't find the very last element in the array, same
449: bug in both the C and the i386 assembly version).
1.205 fefe 450: fixed FNM_PATHNAME in fnmatch
1.204 fefe 451: fix brk (the syscall was documented incorrectly in the Linux man page)
452: Thanks, Thomas Ogrisegg!
1.205 fefe 453: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 454: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 455: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 456:
1.164 fefe 457: 0.12:
458: more contributions from Frank Klemm.
1.165 fefe 459: iconv can now do UCS-2, too.
1.167 fefe 460: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 461: Lots of bug fixes, and several more i386 specific versions of common
462: routines to make them smaller.
1.168 fefe 463: add memmem (a GNU extension that looks useful)
1.170 fefe 464: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 465: add pivot_root syscall, %n for *scanf.
1.169 fefe 466: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 467: add Frank Klemm's optimized md5
1.172 fefe 468: add -Os option to diet (see diet.1).
1.173 fefe 469: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 470: add 32-bit uid/gid syscalls.
1.175 fefe 471: add rand48 (thanks, Johannes Kloos)
1.176 fefe 472: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 473: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
474: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
475: fix gethostent alias list termination. Major oops.
1.178 fefe 476: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 477: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 478: DNS will now properly signal errors and set h_errno.
479: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 480: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
481: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
482: external reference to a symbol that is only in the diet libc. So,
483: when you accidentally link a diet libc compiled object file against
484: glibc, the linker will barf. This will bloat your object files, but
485: you can remove all the references with "strip -R .note" from
486: the binaries in the end (which you should do anyway).
1.182 fefe 487: fix ARM unified syscall (select did not work).
1.183 fefe 488: add getpwent_r ala glibc and replace getpwent
489: do the same for getgrent and getspent
490: remove entlib (new code is smaller)
1.184 fefe 491: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 492: add getpwnam_r and getpwuid_r
1.186 fefe 493: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 494: Olaf muddled with the dynamic linker. It's a clean-room
495: implementation in the sense that it once worked for Olaf in a clean
496: room ;)
1.188 fefe 497: add if_nameindex and if_freenameindex.
498: fixed arm unified syscalls to work with current binutils (; is no
499: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 500: changed all st_[cma]time types to signed long so comparisons against
501: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 502: fixed two bugs regarding ungetc.
503: add getusershell, setusershell, endusershell (for vs_ftpd)
504: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 505: fixed strftime (was completely hosed)
1.192 fefe 506: added real make install target
1.164 fefe 507:
1.115 fefe 508: 0.11:
509: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 510: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 511: add floor, ceil and memchr prototypes.
512: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 513: cleaner errno vs __errno_location handling
514: add placeholder iconv (iconv_open will always return EINVAL)
515: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
516: initialization of getaddrinfo.
1.119 fefe 517: fix vsnprintf %X (printed lower case)
1.120 fefe 518: I wrote a new getopt. It appears to actually work (it is POSIX
519: compliant, it does not sort argv like the GNU version) and is only
520: a little over 300 bytes on x86.
1.121 fefe 521: Guillaume Cottenceau just wrote me that strncat should be even more
522: broken than it already is: it should append n bytes AND THEN \0!
1.463 leitner 523: I wonder how many programmers have produced off-by-one errors here...
1.122 fefe 524: Fix regexec offset return. autoconf now believes that diet libc has
525: POSIX regular expressions.
1.123 fefe 526: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 527: Fix regular expression match for x* when there is no x at all.
1.125 fefe 528: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 529: Add %h to vsnprintf.
1.127 fefe 530: Add FAQ.
1.128 fefe 531: Make %h work for signed numbers and add %hh to vsnprintf.
532: initgroups ignored the group argument :-(
533: remove printf references and nested functions from glob.
1.129 fefe 534: added an errno in libpthread that will display a prominent linker
535: warning.
1.131 fefe 536: started getting rid of kernel headers. Big task! :-(
1.130 fefe 537: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 538: Olaf: added a lot of code in libdl (not yet complete), changed the
539: startup code to make it work with his libdl and ld.so (needs still work
540: too)
1.134 fefe 541: __dns_readstartfiles only took the first domain or search path.
542: Thanks, Anthony de Boer
1.133 olaf 543: Olaf: added clone and a new unified_syscall for PowerPC
544: also dynlinker is now available (i386 only at this time)
1.135 fefe 545: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 546: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 547: fixed word delimiters in regex (they looked for space, i.e. "," did
548: not work as delimiter)
1.138 fefe 549: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 550: added mkdtemp.
1.142 fefe 551: Uwe Ohse reported all of the following bugs:
552: ttyname should return 0 if !isatty.
553: realpath returns NULL if "." cannot be opened
554: putenv erroneously accepted (and mishandled) entries without "=".
555: popen returned 255 instead of 127 if /bin/sh could not be run.
556: fgetc did not set the internal EOF indicator on EOF.
557: bsearch contained an assumption about integer arithmetic overflow
558: behavior.
559: system did not set SIGCHLD and thus contained a race.
560: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 561: daemon did not check whether open returns an fd below 3
562: perror did not save errno.
1.144 olaf 563: Olaf: Peter Jones reported some problems with perror; strerror had the
564: same problem.
565: Peter also posted a patch to atexit/exit. With some modifications it is
566: now implemented.
1.145 fefe 567: Unbuffered stdio and ungetc can no longer be disabled. I will try to
568: implement part of it using ELF weak symbols.
1.146 fefe 569: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 570: Added overflow handling for strtoul and strtol.
1.149 fefe 571: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
572: it before falling back to DNS if enabled.
1.150 fefe 573: Added a littie backwards compatibility cruft for gpm (man, do these
574: sources stink!)
1.151 fefe 575: Added openpty.
1.152 fefe 576: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 577: Fix fseek return value.
1.155 fefe 578: Add dirname and basename.
1.156 fefe 579: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 580: Fixed getservent (did not allow _ and - in the aliases).
581: Thanks, Oden Eriksson
1.158 fefe 582: Added a float.h so configure believes we have ANSI header files.
583: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 584: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 585: scanf and printf function implementations
1.160 fefe 586: Imported a few more functions and optimizations from Frank Klemm (he
587: also rewrote dtostr to have more precision)
1.161 olaf 588: Olaf: checked in a new sig* function family (based on rt_sig*).
589: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 590: Made rudimentary iconv that can convert back and forth between
591: iso-8859-1, utf-8 and ucs-4 (for debugging).
592: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 593:
1.74 fefe 594: 0.10:
595: update getpagesize.
596: add personality.
1.75 fefe 597: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 598: add putchar (apparently arm-linux-gcc will substitute printf("\n")
599: with putchar('\n') behind your back...?!
1.77 fefe 600: import include/scsi/ from glibc.
1.78 fefe 601: add iopl.
1.80 fefe 602: add execl and sigdelset prototypes.
603: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 604: add RPC headers (no code yet).
1.82 fefe 605: add mlockall, munlockall
1.83 fefe 606: make "diet gcc foo.c" work.
607: added Sun RPC code and removed as many warnings as possible in a
608: heroic act of self-mutilation.
609: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 610: added getpass. mount from util-linux actually compiles now!
611: fix the sig*set routines. mount actually works now *bg*
612: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 613: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 614: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 615: add res_init.
616: add asprintf (ugh, what an ugly function).
1.89 fefe 617: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 618: add ut_name alias to ut_host in struct utmp.
619: add inet_ntop, inet_pton, gethostbyname2.

1.93 fefe 621: add endmntent, getmntent, setmntent.
1.94 fefe 622: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 623: add setenv.
624: remove __restrict from mntent.h, add __restrict__ removal alias for
625: older gcc versions in sys/cdefs.h.
626: add rlim_t, sig_atomic_t declarations.
627: add sigsetjmp #define for __sigsetjmp (oops).
628: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 629: add a gruesome hack to printf floating point to accept %f and kludge
630: together support for %.2f. Don't look at the code, please!
1.98 fefe 631: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 632: imported fix for entlib by Jeff Garzik.
1.100 fefe 633: add glob implementation from Guillaume Cottenceau (Thanks!!)
634: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 635: add REG_ICASE and word start/end handling to my regular expressions.
636: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 637: wrap getcwd to comply to man page (the syscall returns the number of
638: bytes, not the buffer)
639: add realpath.
1.103 fefe 640: fix vfprintf.
1.104 fefe 641: fix *scanf %s zero termination.
642: add abs, labs, llabs.
1.105 fefe 643: add <sys/io.h>, ioperm syscall.
644: add flock to <sys/file.h>
1.106 fefe 645: fixes to bsearch and the regular expressions.
1.107 fefe 646: add fake herror.
1.108 fefe 647: add scandir and alphasort.
1.109 fefe 648: add killpg
1.110 fefe 649: implemented a gross hack to make libpthread compile when
650: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 651: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 652: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 653: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
654: for sending a patch.
1.114 fefe 655: add getserv*.
656: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
657: "search" from resolv.conf.
1.74 fefe 658:
1.73 fefe 659: 0.9:
1.65 fefe 660: fixed initgroups (oops)

662: imported vfprintf fix from James Antill.
1.67 fefe 663: add fnmatch
664: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 665: Olaf added character classes to *scanf.
1.69 fefe 666: Put object and library files into a separate directory (bin-$ARCH).
667: Add "cross" make target to make all architectures.
668: Add "diet" program and man page.
1.70 fefe 669: Add getgrnam, getgrgid
1.71 fefe 670: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 671: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 672:
1.64 fefe 673: 0.8:
1.34 fefe 674: vsnprintf(0,...) estimated the length of strings with a padding width
675: incorrectly.
1.35 fefe 676: new reboot() from Olaf.
1.36 fefe 677: added prototypes for getsockopt and setsockopt.
1.39 fefe 678: added experimental sem* and shm*
1.38 fefe 679: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 680: added setvbuf (only changes mode, not buffer)
1.41 fefe 681: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
682: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 683: added qsort() and bsearch(). Benchmark on 1000 random ints:
684: glibc: 679414 cycles qsort and 3352 cycles bsearch
685: diet libc: 300010 cycles qsort, 553 cycles bsearch
686: I have no idea why glibc is so slow.
1.43 fefe 687: added __isnan (references by libm.a from glibc).
688: added popen() and pclose(). Now the diet libc can link slsh (from
689: S-Lang!)
1.44 fefe 690: corrected usleep. It was more of an msleep until now.
1.45 fefe 691: corrected __dtostr (it looped when trying to format "0.0").
692: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 693: added ungetc (does it work?)
1.47 fefe 694: added inet_aton (yuck!)
1.50 fefe 695: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 696: added h_errno and __h_errno_location
697: added inet_ntoa
1.49 fefe 698: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 699: add bcopy, index, rindex macros
700: add isgraph and isxdigit
1.52 fefe 701: add strftime (ugh!!!)
1.53 olaf 702: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 703: Jeff Garzik contributed a spec file. I put it in contrib and hope
704: everbody knows what to do with it...
705: Olaf checked in a ton of libpthread stuff.
1.55 fefe 706: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 707: add large file backwards compatibility support (so gzip will run on
708: kernel 2.2 and 2.0)
1.57 fefe 709: added shutdown
1.58 fefe 710: added nice
711: added pseudo-locale support for is* (they are now weak aliases,
712: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
713: overwrite the default is* functions.
1.59 fefe 714: added liblatin1.a
1.60 fefe 715: added tzfile implementation (does it work for anyone else?)
1.61 fefe 716: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 717: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
718: Thanks!
1.63 fefe 719: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 720:
1.21 fefe 721: 0.7.2:
722: added several prototypes to already implemented functions and
723: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 724: added prototypes for process group and dup syscalls. Thanks to
725: Abraham again. He also contributed an implementation for daemon(),
726: an ugly BSD hack. I decided to diversify the lib/ directory a
727: little and now created a libugly/ directory for stuff like system()
728: and daemon() ;-)
729: added libstdio and moved all that stdio crap from lib/ there. The
730: idea is to start separating now what we will separate for shared
731: libraries anyway.
1.26 fefe 732: optimized x86 unified-syscall by Olaf.
1.27 fefe 733: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
734: limits.h instead)
735: added remove.c and enough cruft to limits.h to make it compile lzo,
736: lzop and bzip2.
1.28 fefe 737: added mktime, asctime_r, asctime and ctime (needed for gzip).
738: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 739: format some day (man tzfile, ugh!) :-(
1.29 fefe 740: added unlink prototype to unistd.h.
741: added gmtime and gmtime_r.
1.31 fefe 742: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 743: removed readdir glibc compatibility cruft.
1.31 fefe 744: removed stat glibc compatibility cruft.
1.32 fefe 745: oops, my fread was broken for pipes.
1.33 fefe 746: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 747:
1.9 fefe 748: 0.7.1:
1.11 fefe 749: optimized away the static arrays from __ltostr and __lltostr.
750: optimized away the static arrays (and more!) from strtoul and strtoull.
751: added system (by Olaf).
1.12 fefe 752: added tolower and toupper
1.13 fefe 753: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 754: added clone for mips (by Olaf).
755: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 756: added pause for all (by Olaf).
1.17 fefe 757: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 758: added isupper and islower.
759: added putc and putchar as macros.
1.17 fefe 760: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
761: insightful discussions and patches I partially used for the last three)
1.18 fefe 762: added getpriority and setpriority (also by Abraham)
1.19 fefe 763: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 764: oi, setjmp and longjmp were broken on other platforms, too!
765: Thanks to Sébastien Côté for reporting this.
1.9 fefe 766:
767: 0.7:
1.6 olaf 768: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 769: Initial dynamic loading glue for i386, also by Olaf.
770: We don't have a dynamic loader yet, so this is not yet usable.
771: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
772: vsprintf, writev, all by Olaf.
1.2 fefe 773: imported readdir fix from Guillaume. Mhh, can the kernel interface
774: really be this broken?
1.3 fefe 775: Found a kludgy way to detect whether the kernel includes define struct
776: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
777: not work for you, please tell me!
1.4 fefe 778: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 779: Fixed stdio line buffering. The code was already there but I forgot
780: to mark stdio and stdout as line buffered. This should really be
781: done dynamically using isatty, though.
1.8 fefe 782: Removed superfluous "if (1)" in execvp.c
1.1 cvs 783:
784: 0.6.14:
785: *scanf did not append the 0 byte for %s.
786: added creat and changed creat to call open directly instead of open64.
787: did for fread what 0.6.10 did for fwrite.
788: repaired buffered stdio a little (line buffering is still not
789: supported).
790: [All of these bugs have been reported by Guillaume. Thanks!]
791: added __pure__ to strchr and strrchr in <string.h>
792:
793: 0.6.13:
794: included COPYING to make clear that the diet libc is covered by the
795: GNU General Public License (and _not_ the LGPL). That means that
796: you need to obtain a license from me if you want to use the diet
797: libc in a proprietary program that you want to distribute.
798: The x86 unified syscall swapped arguments #4 and #5 and noone
799: noticed until now! Thanks to Guillaume Cottenceau for reporting
800: this!
801: The malloc had a subtle bug with small allocations that could cause
802: segfault. Guillaume reported it, Olaf fixed it.
803:
804: 0.6.12:
805: added assert, statfs and fstatfs
806: added include/net/if.h so fget compiles again.
807:
808: 0.6.11:
809: added putenv.
810:
811: 0.6.10:
812: fixed fwrite. It returned the number of bytes written, not the number
813: of records. Thanks to Albert D. Cahalan for pointing this out.
814: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
815: added brk and sbrk. harold@nb.com.sg made me do it.
816:
817: 0.6.9:
818: fixed execvp not to return on ENOENT
819: did for {open|read|close|seek|tell}dir what I did for stat before.
820: The glibc compatibility part is currently non-functional.
821: fixed white space handling in sscanf " (" would not match " (".
822: fixed printf to accept 'l' flag.
823: fixed getpwuid (ignored last line)
824:
825: 0.6.8:
826: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
827: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
828: added strlcpy and strlcat from OpenBSD.
829: added stat64, fstat64 and lstat64.
830: added endian.h and made ending of strlen.c endianness-aware
831: added string routines size tweak to dietfeatures.h. Most of the
832: string routines have been unrolled. This is up to three times as
833: fast but creates up to three times larger code. Now you can disable
834: the unrolling.
835: added sendfile.
836: I also added pread. It works on x86 and sparc but not on ppc and mips.
837: I have no idea what's going on. strace disagrees with the kernel.
838: Can anyone help? I asked the Linux kernel mailing list for help, too.
839: added a few aliases of the type __libc_open for open. nm on
840: libpthreads.so indicates that we will need them.
841:
842: 0.6.7:
843: the sources now compile without warnings with -Wall.
844: printf now prints "(null)" when %s is passed NULL. This can be
845: removed with WANT_NULL_PRINTF in dietfeatures.h
846: added vfprintf, execl, ttyname.
847: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
848: __dietfstat so they can use the normal kernel struct stat.
849: stat, lstat and fstat are now C wrappers that convert to the glibc
850: struct stat. So we can avoid that overhead for programs that use
851: dietlibc headers.
852:
853: 0.6.6:
854: changed the Makefiles so you can now set CFLAGS on the command line
855: added memccmp (analogous to memccpy) and strncmp.
856: Olaf fixed another bug in the sparc unified syscall.
857: Paul Clifford contributed a C version of his strlen.S that is much
858: more efficient than the previous strlen on all platforms! It also
859: looks like technology from Roswell. ;-}
860: added a "real" stdio. Well, almost. Please contribute!
861: added dietfeatures.h so you can remove features you don't need.
862: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
863: stdio now works with simple programs and minigzip from libz.
864: stdio uses some major trickery to avoid linking the stdio, stderr and
865: stdout (and reserving space for them) when they are not used.
866:
867: 0.6.5:
868: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
869: most of them bugs in the new header files, but also missing sigset
870: functions.
871: Paul Clifford contributed an assembly strlen.S for ARM and fixed
872: several bugs.
873: Fixed ppc/setjmp and mips/pipe.
874: Olaf contributed a new sparc unified syscall.
875:
876: 0.6.4:
877: declared is* static inline in getservent.
878: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
879: changed strlen to return 0 when passed NULL.
880: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
881: Scientist who actually implemented this without access to a MIPS
882: box, just from reading the architecture manual. And it worked out
883: of the box.
884: started a set of system includes, mainly so that I can use lcc and
885: my alpha-linux cross compiler (which is unable to cross-compile
886: glibc). diet libc can now be compiled without any include files
887: from a normal libc. The includes do declare more than diet libc
888: currently delivers and they are still far from complete for real
889: applications.
890: I will only add assembly versions that are smaller _and_ faster than
891: the C version. Larger routines are only accepted if they are called
892: very often and are substantially faster.
893: added i386 assembly strchr, which is smaller and faster than the old
894: version. It is, however, larger than the version contributed by
895: proton (thanks, anyway).
896: added i386 strlen (31% faster, 14% smaller)
897: "make t" will now create a map file called "mapfile".
898:
899: 0.6.3:
900: added sys_errlist, strerror and perror
901: added isblank
902: added atol
903:
904: 0.6.2:
905: mmap for ARM didn't compile. Thanks, Paul!
906:
907: 0.6.1:
908: split mmap into the architecture specific subdirectories.
909: getenv now copes with environ==NULL, thanks Paul Clifford.
910: Paul also contributed a smaller ARM startup code.
911:
912: 0.6:
913: strcat returned the wrong result. Thanks, Dietz Pröpper.
914: strtod now understands a negative exponent (oops, thanks Bertram Barth)
915: Port to arm-linux-gnu, but on the Netwinder I use for testing the
916: __dtostr does not work (I have no idea why!)
917: The MIPS port now uses (much smaller) non-PIC code. That means that
918: the applications you link against diet libc also have to be compiled
919: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
920: Thanks to Ralf Bächle for helping me with this!
921: I made subdirectories for the architectures and use VPATH to override
922: VPATH so that make finds the source file automatically. That should
923: simplify the sources greatly.
924: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
925: ARM and MIPS now also have setjmp and longjmp
926: "compile" and "load" are now make targets. Use them for djb programs.
927: added contrib/elftrunc.c which will remove unnecessary ELF headers.
928: Again, contributed from Olaf. Great work!
929:
930: 0.5.12:
931: printf also does signed numbers.
932: If you don't use atexit, dietlibc now does not link exit, only _exit.
933: *printf now correctly returns the number of bytes written.
934: Olaf contributed experimental sscanf and vsscanf implementations.
935: If passed NULL as buffer, snprintf will not write anything but still
936: return the number of bytes it would have written.
937: Initial MIPS port! (Oh, the agony!)
938: No setjmp and longjmp support yet! Please contribute!
939: I even implemented unified syscalls for MIPS. Still, MIPS code is
940: almost twice the size of SPARC code. If anyone knows why: please
941: tell me!
942:
943: 0.5.11:
944: I implemented new unified syscalls for x86, sparc and ppc, this time based
945: on .s files and not .c files, and I moved the syscalls into
946: subdirectores to clean the dietlibc sources up a little.
947: A binary consisting of printf("%s is %d\n","olaf",23) is now
948: 2864 bytes on sparc
949: 2488 bytes on intel
950: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
951: to make a few more applications work.
952: Olaf Dreesen also implemented some unified syscall stuff for x86.
953: He discovered that with our unified syscall interface it actually
954: costs <10 bytes total to make all system calls thread safe!
955: I implemented atexit() (can register up to 4 callbacks).
956: I implemented strtod and __dtostr (the opposite). Now we can add
957: floating point support to vsnprintf and sscanf!
958:
959: 0.5.10:
960: I actually saw that I can not only merge the errno handling code of
961: the system calls on x86, I can also merge the rest (including the
962: arguments) except for setting the system call number. All those
963: system calls are now just a jump to a unified system call handler.
964: I got rid of x86openclose again. The savings are substantial:
965: chown from embutils went from 7664 to 7184 bytes!
966: If I'd move the system call wrappers to assembly language, I could
967: even reduce the alignment (does not matter since it's just a jump
968: anyway) and get rid of the "ret" behind each jump (one byte per
969: system call!)
970:
971: 0.5.9:
972: added memchr, strpbrk, strstr, strtol, isspace (hehe)
973: fixed strdup
974: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
975: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
976: (no signed integers, only strings and unsigned integers (but
977: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
978: that code must be wonderful, I don't understand it at all *bg*)
979: Olaf's printf does understand padding like in "%08d" and "%8d" and
980: automatically pads pointers with '0'.
981: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
982: Thanks to proton for inspiration on this.
983: The new x86 start code also does not reference exit any more, thus saving
984: 64 bytes for executables that don't call exit explicitly.
985: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
986: Moved errno and environ to start.S, saving no byte binary size but
987: speeding up compilation and slightly shortening dietlibc.a ;-)
988: For x86: joined open and close into one assembler file, sharing the
989: errno handling. This is a feasibility test and it actually saves a
990: few bytes. I think I will reimplement the _syscall[1-6] macros on
991: all platforms now to share the errno handling code for them.
992:
993: 0.5.8:
994: fixed strchr to be able to look for 0.
995:
996: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
997: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
998: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
999: contributed by Olaf Dreesen)
1000:
1001: added execvp, getcwd
1002:
1003: fixed __xmknod
1004:
1005: Note: can it be that the ftw interface really is so broken that I
1006: cannot implement it without having to implement some searching data
1007: structure? I included an experimental ftw implementation that will
1008: not follow symlinks.
1009:
1010: 0.5.7:
1011: oops, if_nametoindex was broken!
1012:
1013: 0.5.6:
1014: ported to ppc-linux.
1015: fixed i386 sigsetjmp (I mistyped the function name)
1016: included sigjmp.c
1017:
1018: 0.5.5:
1019: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
1020: actually, it wasn't fork that wasn't working for sparc, it was pipe.
1021: I fixed it now.
1022: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
1023: fixed readdir to use getdents and not the intel inline asm
1024:
1025: 0.5.4:
1026: ported to sparclinux (sparc32 only). Beware: does not work yet.
1027: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
1028:
1029: 0.5.3:
1030: added tcsetattr and getenv to compile e3
1031:
1032: 0.5.2:
1033: added vhangup, tcgetattr, isatty and memcmp for fgetty
1034: (http://www.fefe.de/fgetty/)
1035: added localtime from uC-libc.
1036:
1037: 0.5.1:
1038: stat and friends actually work now. Yuck! Another case of
1039: translation between kernel and userland. Why can't the kernel
1040: people and the libc people simply agree on a standard?
1041: removed many unnecessary includes to speed up compilation.
1042: added -fomit-frame-pointer and i386 compilation target to reduce code size.
1043: inlined socketcall to reduce code size.
1044: "load" and "compile" are examples for djb code.
1045:
1046: 0.5:
1047: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
1048: each object file is now treated with "strip -x -R .note -R .comment"
1049: split each system call into a separate object file
1050: added ntohs, htons, alarm, if_indextoname and if_nametoindex
1051:
1052: 0.4.1:
1053: oops, the strchr implementation was wrong. Thanks Jens Laas!
1054:
1055: 0.4:
1056: copied opendir and friends from uC-libc.
1057: added getservent and getservby* in gerservent.c
1058:
1059: 0.3:
1060: remove readdir system call
1061: added getdents system call
1062: added getpwnam/getpwuid implementation in getpwnam.c
1063: added a few string functions (in str*.c)
1064:
