1.333 fefe 120: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
121: the built-in defaults.

1.284 fefe 158: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.285 fefe 159: Michal Ludvig ported the diet libc to the x86_64 architecture (the

202: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 203: Thomas also sent me profiling support (so far only on x86, but
204: profiling/PORTING describes what needs to be done for other
205: architectures)!
1.272 fefe 206: add contrib/dprof.c, also from Thomas.
1.269 fefe 207: Andreas Krennmair sent a patch to add the BSD regex interface to
208: libcompat

1.277 fefe 213: fix some nasty regular expression bugs
214: write a stupid malloc checker (contrib/debug-realloc.c) to help me

1.278 fefe 216: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 217: fix DNS domain search
1.280 fefe 218: i386 memccpy exchanged esi and edi :-( I should do more checks before

1.244 fefe 221: 0.16:
222: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 223: Andre found two very embarassing bugs in my four lines of md5 glue.
224: I need to get more sleep.
1.247 fefe 225: Thanks Ogrisegg found that ptrace does not work as documented and
226: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 227: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
228: fix ptrace.h for S/390 and ARM
229: provide a PORTING document so we don't lose track of which file need
230: to be touched to port the diet libc to a new platform.
1.249 fefe 231: remove a few warnings
232: provide a prototype for usleep.
1.250 fefe 233: make __dtostr work on ARM by using long instead of long long.
234: Idea by Dirk Engling.
1.251 fefe 235: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 236: Forgot an #endif in asm/sigcontext.h (Mike Castle)

1.254 fefe 239: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
240: create libcompat.a (and move daemon to it)
1.255 fefe 241: add getdelim and getline
242: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 243: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 244: Olaf: fixed *scanf familie. It hadn't wored with "long long".

1.224 fefe 253: 0.15:
1.225 fefe 254: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 255: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 256: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
257: thread-safe!
1.228 fefe 258: remove vfork and add alarm to dynamic syscalls.
259: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 260: The MD5 code generated unaligned accesses when passed an unaligned
261: pointer on little endian ARM and MIPS.
262: MIPS unified syscall didn't compile anymore.
263: Put up new mipsel target to cross compile for little endian mips.
264: The mips target will again explicitly set endianness to big endian.
265: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 266: Duh, when we removed return0, we broke tzset when the time zone parser
267: was disabled. Uwe Ohse noticed this. Thanks!
268: Fix gethostbyname to match host names case insensitively in /etc/hosts.
269: Oops, this was reported 6 weeks ago but I overlooked the email.
270: Thanks, Denis Rachal!
1.231 fefe 271: vsnprintf's zero termination was broken.
1.233 fefe 272: Uwe Ohse found a few more bugs:
273: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
274: does it correctly.
275: Make inet_aton use strtoul instead of strtol
276: fdopen would close the file descriptor if it could not malloc the
277: buffer.
278: strftime updates.
279: Make _FILE_OFFSET_BITS includes -Wundef clean
280: Andre found a typo in endian.h for big endian mips
1.234 fefe 281: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 282: strstr(whatever,"") returned NULL, not whatever. Found by a new test
283: suite entry for strstr that I wrote.
1.245 fefe 284: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 285: add <asm/sigcontext.h> for profiling support.
286: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 287: an i386 assembler getenv implementation (roughly half the size)
288: add grantpt, ptsname, unlockpt
1.236 fefe 289: add a getenv test suite entry.
1.238 fefe 290: Andre contributed an ARM assembler md5 implementation and he fixed mmap
291: on ARM.
292: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 293: getservent_r did not parse lines without aliases. Thanks, Jaroslav
294: Macodiseas!
1.240 fefe 295: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 296: removed annoying -Wconversion gcc switch
1.242 fefe 297: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 298: Kurt Garloff sent these diffs:
299: add fdatasync (and make it a pthread cancellation point)
300: numerous alpha issues, like using .quad instead of .long for
301: offsets, change strip to -strip in Makefile (so a failing strip does
302: not abort the make), try to be more friendly to the gcc 2.96 that
303: SuSE 7.1 AXP ships with.
1.224 fefe 304:
1.209 fefe 305: 0.14:
1.224 fefe 306: fix brk again (missing __brk, trivial oversight)
1.210 fefe 307: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
308: Thomas Ogrisegg!
1.211 fefe 309: Thomas also contributed a PA-RISC port including testandset, so
310: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 311: made the fake locale more believable.
312: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 313: moved _exit into the unified syscall on x86.
1.214 fefe 314: Uwe Ohse found many more bugs:
315: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
316: liblatin1 was more or less completely broken if you gave it chars as
317: arguments, not ints (signedness). execvp had a buffer overflow in
318: case a PATH element exceeded PATH_MAX, but it's not a security
319: problem since setuid programs need to set their path to some known
320: value anyway.
1.219 fefe 321: hasmntopt did not work with foo=bar style options
1.217 fefe 322: Uwe also improved ftw's stack usage.
1.214 fefe 323: Put movl instead of popl rationale in comment in i386/unified.S since
324: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 325: I discovered __attribute__((malloc)) and started using it. For gcc 3,
326: it improves the optimizer when functions return malloced pointers.
1.216 fefe 327: Steven Rostedt pointed out that my setvbuf was broken with regard to
328: size==0 and sent a patch to fix it.
1.218 fefe 329: Thomas Ogrisegg made setenv smaller.
1.220 olaf 330: Olaf: implemented the parisc clone and an atomic testandset, modified the
331: libpthread to respect the parisc UPgrowing stack. still non functional,
332: because the unified syscall uses errno :(
1.221 fefe 333: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 334: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
335: don't write anything which was no longer the case. It also
336: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 337: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 338:
1.193 fefe 339: 0.13:
1.194 fefe 340: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 341: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 342: Olaf: port to S/390!
1.196 leitner 343: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 344: res_query did not initialize last
1.199 fefe 345: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 346: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 347: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 348: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 349: rewrote __dtostr (it also has one more argument now)
1.205 fefe 350: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 351: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
352: fix strncat for the case where n == 0 (security implications?)
353: fix bsearch (it didn't find the very last element in the array, same
354: bug in both the C and the i386 assembly version).
1.205 fefe 355: fixed FNM_PATHNAME in fnmatch
1.204 fefe 356: fix brk (the syscall was documented incorrectly in the Linux man page)
357: Thanks, Thomas Ogrisegg!
1.205 fefe 358: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 359: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 360: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 361:
1.164 fefe 362: 0.12:
363: more contributions from Frank Klemm.
1.165 fefe 364: iconv can now do UCS-2, too.
1.167 fefe 365: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 366: Lots of bug fixes, and several more i386 specific versions of common
367: routines to make them smaller.
1.168 fefe 368: add memmem (a GNU extension that looks useful)
1.170 fefe 369: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 370: add pivot_root syscall, %n for *scanf.
1.169 fefe 371: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 372: add Frank Klemm's optimized md5
1.172 fefe 373: add -Os option to diet (see diet.1).
1.173 fefe 374: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 375: add 32-bit uid/gid syscalls.
1.175 fefe 376: add rand48 (thanks, Johannes Kloos)
1.176 fefe 377: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 378: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
379: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
380: fix gethostent alias list termination. Major oops.
1.178 fefe 381: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 382: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 383: DNS will now properly signal errors and set h_errno.
384: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 385: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
386: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
387: external reference to a symbol that is only in the diet libc. So,
388: when you accidentally link a diet libc compiled object file against
389: glibc, the linker will barf. This will bloat your object files, but
390: you can remove all the references with "strip -R .note" from
391: the binaries in the end (which you should do anyway).
1.182 fefe 392: fix ARM unified syscall (select did not work).
1.183 fefe 393: add getpwent_r ala glibc and replace getpwent
394: do the same for getgrent and getspent
395: remove entlib (new code is smaller)
1.184 fefe 396: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 397: add getpwnam_r and getpwuid_r
1.186 fefe 398: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 399: Olaf muddled with the dynamic linker. It's a clean-room
400: implementation in the sense that it once worked for Olaf in a clean
401: room ;)
1.188 fefe 402: add if_nameindex and if_freenameindex.
403: fixed arm unified syscalls to work with current binutils (; is no
404: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 405: changed all st_[cma]time types to signed long so comparisons against
406: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 407: fixed two bugs regarding ungetc.
408: add getusershell, setusershell, endusershell (for vs_ftpd)
409: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 410: fixed strftime (was completely hosed)
1.192 fefe 411: added real make install target
1.164 fefe 412:
1.115 fefe 413: 0.11:
414: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 415: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 416: add floor, ceil and memchr prototypes.
417: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 418: cleaner errno vs __errno_location handling
419: add placeholder iconv (iconv_open will always return EINVAL)
420: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
421: initialization of getaddrinfo.
1.119 fefe 422: fix vsnprintf %X (printed lower case)
1.120 fefe 423: I wrote a new getopt. It appears to actually work (it is POSIX
424: compliant, it does not sort argv like the GNU version) and is only
425: a little over 300 bytes on x86.
1.121 fefe 426: Guillaume Cottenceau just wrote me that strncat should be even more
427: broken than it already is: it should append n bytes AND THEN \0!
428: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 429: Fix regexec offset return. autoconf now believes that diet libc has
430: POSIX regular expressions.
1.123 fefe 431: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 432: Fix regular expression match for x* when there is no x at all.
1.125 fefe 433: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 434: Add %h to vsnprintf.
1.127 fefe 435: Add FAQ.
1.128 fefe 436: Make %h work for signed numbers and add %hh to vsnprintf.
437: initgroups ignored the group argument :-(
438: remove printf references and nested functions from glob.
1.129 fefe 439: added an errno in libpthread that will display a prominent linker
440: warning.
1.131 fefe 441: started getting rid of kernel headers. Big task! :-(
1.130 fefe 442: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 443: Olaf: added a lot of code in libdl (not yet complete), changed the
444: startup code to make it work with his libdl and ld.so (needs still work
445: too)
1.134 fefe 446: __dns_readstartfiles only took the first domain or search path.
447: Thanks, Anthony de Boer
1.133 olaf 448: Olaf: added clone and a new unified_syscall for PowerPC
449: also dynlinker is now available (i386 only at this time)
1.135 fefe 450: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 451: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 452: fixed word delimiters in regex (they looked for space, i.e. "," did
453: not work as delimiter)
1.138 fefe 454: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 455: added mkdtemp.
1.142 fefe 456: Uwe Ohse reported all of the following bugs:
457: ttyname should return 0 if !isatty.
458: realpath returns NULL if "." cannot be opened
459: putenv erroneously accepted (and mishandled) entries without "=".
460: popen returned 255 instead of 127 if /bin/sh could not be run.
461: fgetc did not set the internal EOF indicator on EOF.
462: bsearch contained an assumption about integer arithmetic overflow
463: behavior.
464: system did not set SIGCHLD and thus contained a race.
465: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 466: daemon did not check whether open returns an fd below 3
467: perror did not save errno.
1.144 olaf 468: Olaf: Peter Jones reported some problems with perror; strerror had the
469: same problem.
470: Peter also posted a patch to atexit/exit. With some modifications it is
471: now implemented.
1.145 fefe 472: Unbuffered stdio and ungetc can no longer be disabled. I will try to
473: implement part of it using ELF weak symbols.
1.146 fefe 474: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 475: Added overflow handling for strtoul and strtol.
1.149 fefe 476: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
477: it before falling back to DNS if enabled.
1.150 fefe 478: Added a littie backwards compatibility cruft for gpm (man, do these
479: sources stink!)
1.151 fefe 480: Added openpty.
1.152 fefe 481: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 482: Fix fseek return value.
1.155 fefe 483: Add dirname and basename.
1.156 fefe 484: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 485: Fixed getservent (did not allow _ and - in the aliases).
486: Thanks, Oden Eriksson
1.158 fefe 487: Added a float.h so configure believes we have ANSI header files.
488: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 489: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 490: scanf and printf function implementations
1.160 fefe 491: Imported a few more functions and optimizations from Frank Klemm (he
492: also rewrote dtostr to have more precision)
1.161 olaf 493: Olaf: checked in a new sig* function family (based on rt_sig*).
494: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 495: Made rudimentary iconv that can convert back and forth between
496: iso-8859-1, utf-8 and ucs-4 (for debugging).
497: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 498:
1.74 fefe 499: 0.10:
500: update getpagesize.
501: add personality.
1.75 fefe 502: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 503: add putchar (apparently arm-linux-gcc will substitute printf("\n")
504: with putchar('\n') behind your back...?!
1.77 fefe 505: import include/scsi/ from glibc.
1.78 fefe 506: add iopl.
1.80 fefe 507: add execl and sigdelset prototypes.
508: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 509: add RPC headers (no code yet).
1.82 fefe 510: add mlockall, munlockall
1.83 fefe 511: make "diet gcc foo.c" work.
512: added Sun RPC code and removed as many warnings as possible in a
513: heroic act of self-mutilation.
514: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 515: added getpass. mount from util-linux actually compiles now!
516: fix the sig*set routines. mount actually works now *bg*
517: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 518: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 519: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 520: add res_init.
521: add asprintf (ugh, what an ugly function).
1.89 fefe 522: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 523: add ut_name alias to ut_host in struct utmp.
524: add inet_ntop, inet_pton, gethostbyname2.

1.94 fefe 527: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 528: add setenv.
529: remove __restrict from mntent.h, add __restrict__ removal alias for
530: older gcc versions in sys/cdefs.h.
531: add rlim_t, sig_atomic_t declarations.
532: add sigsetjmp #define for __sigsetjmp (oops).
533: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 534: add a gruesome hack to printf floating point to accept %f and kludge
535: together support for %.2f. Don't look at the code, please!
1.98 fefe 536: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 537: imported fix for entlib by Jeff Garzik.
1.100 fefe 538: add glob implementation from Guillaume Cottenceau (Thanks!!)
539: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 540: add REG_ICASE and word start/end handling to my regular expressions.
541: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 542: wrap getcwd to comply to man page (the syscall returns the number of
543: bytes, not the buffer)
544: add realpath.
1.103 fefe 545: fix vfprintf.
1.104 fefe 546: fix *scanf %s zero termination.
547: add abs, labs, llabs.
1.105 fefe 548: add <sys/io.h>, ioperm syscall.
549: add flock to <sys/file.h>
1.106 fefe 550: fixes to bsearch and the regular expressions.
1.107 fefe 551: add fake herror.
1.108 fefe 552: add scandir and alphasort.
1.109 fefe 553: add killpg
1.110 fefe 554: implemented a gross hack to make libpthread compile when
555: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 556: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 557: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 558: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
559: for sending a patch.
1.114 fefe 560: add getserv*.
561: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
562: "search" from resolv.conf.
1.74 fefe 563:
1.73 fefe 564: 0.9:
1.65 fefe 565: fixed initgroups (oops)
1.66 fefe 566: Cleanup appending file open for stdio (thanks, James Antill)
567: imported vfprintf fix from James Antill.
1.67 fefe 568: add fnmatch
569: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 570: Olaf added character classes to *scanf.
1.69 fefe 571: Put object and library files into a separate directory (bin-$ARCH).
572: Add "cross" make target to make all architectures.
573: Add "diet" program and man page.
1.70 fefe 574: Add getgrnam, getgrgid
1.71 fefe 575: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 576: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 577:
1.64 fefe 578: 0.8:
1.34 fefe 579: vsnprintf(0,...) estimated the length of strings with a padding width
580: incorrectly.
1.35 fefe 581: new reboot() from Olaf.
1.36 fefe 582: added prototypes for getsockopt and setsockopt.
1.39 fefe 583: added experimental sem* and shm*
1.38 fefe 584: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 585: added setvbuf (only changes mode, not buffer)
1.41 fefe 586: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
587: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 588: added qsort() and bsearch(). Benchmark on 1000 random ints:
589: glibc: 679414 cycles qsort and 3352 cycles bsearch
590: diet libc: 300010 cycles qsort, 553 cycles bsearch
591: I have no idea why glibc is so slow.
1.43 fefe 592: added __isnan (references by libm.a from glibc).
593: added popen() and pclose(). Now the diet libc can link slsh (from
594: S-Lang!)
1.44 fefe 595: corrected usleep. It was more of an msleep until now.
1.45 fefe 596: corrected __dtostr (it looped when trying to format "0.0").
597: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 598: added ungetc (does it work?)
1.47 fefe 599: added inet_aton (yuck!)
1.50 fefe 600: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 601: added h_errno and __h_errno_location
602: added inet_ntoa
1.49 fefe 603: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 604: add bcopy, index, rindex macros
605: add isgraph and isxdigit
1.52 fefe 606: add strftime (ugh!!!)
1.53 olaf 607: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 608: Jeff Garzik contributed a spec file. I put it in contrib and hope
609: everbody knows what to do with it...
610: Olaf checked in a ton of libpthread stuff.
1.55 fefe 611: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 612: add large file backwards compatibility support (so gzip will run on
613: kernel 2.2 and 2.0)
1.57 fefe 614: added shutdown
1.58 fefe 615: added nice
616: added pseudo-locale support for is* (they are now weak aliases,
617: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
618: overwrite the default is* functions.
1.59 fefe 619: added liblatin1.a
1.60 fefe 620: added tzfile implementation (does it work for anyone else?)
1.61 fefe 621: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 622: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
623: Thanks!
1.63 fefe 624: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 625:
1.21 fefe 626: 0.7.2:
627: added several prototypes to already implemented functions and
628: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 629: added prototypes for process group and dup syscalls. Thanks to
630: Abraham again. He also contributed an implementation for daemon(),
631: an ugly BSD hack. I decided to diversify the lib/ directory a
632: little and now created a libugly/ directory for stuff like system()
633: and daemon() ;-)
634: added libstdio and moved all that stdio crap from lib/ there. The
635: idea is to start separating now what we will separate for shared
636: libraries anyway.
1.26 fefe 637: optimized x86 unified-syscall by Olaf.
1.27 fefe 638: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
639: limits.h instead)
640: added remove.c and enough cruft to limits.h to make it compile lzo,
641: lzop and bzip2.
1.28 fefe 642: added mktime, asctime_r, asctime and ctime (needed for gzip).
643: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 644: format some day (man tzfile, ugh!) :-(
1.29 fefe 645: added unlink prototype to unistd.h.
646: added gmtime and gmtime_r.
1.31 fefe 647: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 648: removed readdir glibc compatibility cruft.
1.31 fefe 649: removed stat glibc compatibility cruft.
1.32 fefe 650: oops, my fread was broken for pipes.
1.33 fefe 651: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 652:
1.9 fefe 653: 0.7.1:
1.11 fefe 654: optimized away the static arrays from __ltostr and __lltostr.
655: optimized away the static arrays (and more!) from strtoul and strtoull.
656: added system (by Olaf).
1.12 fefe 657: added tolower and toupper
1.13 fefe 658: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 659: added clone for mips (by Olaf).
660: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 661: added pause for all (by Olaf).
1.17 fefe 662: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 663: added isupper and islower.
664: added putc and putchar as macros.
1.17 fefe 665: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
666: insightful discussions and patches I partially used for the last three)
1.18 fefe 667: added getpriority and setpriority (also by Abraham)
1.19 fefe 668: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 669: oi, setjmp and longjmp were broken on other platforms, too!
670: Thanks to Sébastien Côté for reporting this.
1.9 fefe 671:
672: 0.7:
1.6 olaf 673: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 674: Initial dynamic loading glue for i386, also by Olaf.
675: We don't have a dynamic loader yet, so this is not yet usable.
676: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
677: vsprintf, writev, all by Olaf.
1.2 fefe 678: imported readdir fix from Guillaume. Mhh, can the kernel interface
679: really be this broken?
1.3 fefe 680: Found a kludgy way to detect whether the kernel includes define struct
681: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
682: not work for you, please tell me!
1.4 fefe 683: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 684: Fixed stdio line buffering. The code was already there but I forgot
685: to mark stdio and stdout as line buffered. This should really be
686: done dynamically using isatty, though.
1.8 fefe 687: Removed superfluous "if (1)" in execvp.c
1.1 cvs 688:
689: 0.6.14:
690: *scanf did not append the 0 byte for %s.
691: added creat and changed creat to call open directly instead of open64.
692: did for fread what 0.6.10 did for fwrite.
693: repaired buffered stdio a little (line buffering is still not
694: supported).
695: [All of these bugs have been reported by Guillaume. Thanks!]
696: added __pure__ to strchr and strrchr in <string.h>
697:
698: 0.6.13:
699: included COPYING to make clear that the diet libc is covered by the
700: GNU General Public License (and _not_ the LGPL). That means that
701: you need to obtain a license from me if you want to use the diet
702: libc in a proprietary program that you want to distribute.
703: The x86 unified syscall swapped arguments #4 and #5 and noone
704: noticed until now! Thanks to Guillaume Cottenceau for reporting
705: this!
706: The malloc had a subtle bug with small allocations that could cause
707: segfault. Guillaume reported it, Olaf fixed it.
708:
709: 0.6.12:
710: added assert, statfs and fstatfs
711: added include/net/if.h so fget compiles again.
712:
713: 0.6.11:
714: added putenv.
715:
716: 0.6.10:
717: fixed fwrite. It returned the number of bytes written, not the number
718: of records. Thanks to Albert D. Cahalan for pointing this out.
719: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
720: added brk and sbrk. harold@nb.com.sg made me do it.
721:
722: 0.6.9:
723: fixed execvp not to return on ENOENT
724: did for {open|read|close|seek|tell}dir what I did for stat before.
725: The glibc compatibility part is currently non-functional.
726: fixed white space handling in sscanf " (" would not match " (".
727: fixed printf to accept 'l' flag.
728: fixed getpwuid (ignored last line)
729:
730: 0.6.8:
731: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
732: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
733: added strlcpy and strlcat from OpenBSD.
734: added stat64, fstat64 and lstat64.
735: added endian.h and made ending of strlen.c endianness-aware
736: added string routines size tweak to dietfeatures.h. Most of the
737: string routines have been unrolled. This is up to three times as
738: fast but creates up to three times larger code. Now you can disable
739: the unrolling.
740: added sendfile.
741: I also added pread. It works on x86 and sparc but not on ppc and mips.
742: I have no idea what's going on. strace disagrees with the kernel.
743: Can anyone help? I asked the Linux kernel mailing list for help, too.
744: added a few aliases of the type __libc_open for open. nm on
745: libpthreads.so indicates that we will need them.
746:
747: 0.6.7:
748: the sources now compile without warnings with -Wall.
749: printf now prints "(null)" when %s is passed NULL. This can be
750: removed with WANT_NULL_PRINTF in dietfeatures.h
751: added vfprintf, execl, ttyname.
752: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
753: __dietfstat so they can use the normal kernel struct stat.
754: stat, lstat and fstat are now C wrappers that convert to the glibc
755: struct stat. So we can avoid that overhead for programs that use
756: dietlibc headers.
757:
758: 0.6.6:
759: changed the Makefiles so you can now set CFLAGS on the command line
760: added memccmp (analogous to memccpy) and strncmp.
761: Olaf fixed another bug in the sparc unified syscall.
762: Paul Clifford contributed a C version of his strlen.S that is much
763: more efficient than the previous strlen on all platforms! It also
764: looks like technology from Roswell. ;-}
765: added a "real" stdio. Well, almost. Please contribute!
766: added dietfeatures.h so you can remove features you don't need.
767: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
768: stdio now works with simple programs and minigzip from libz.
769: stdio uses some major trickery to avoid linking the stdio, stderr and
770: stdout (and reserving space for them) when they are not used.
771:
772: 0.6.5:
773: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
774: most of them bugs in the new header files, but also missing sigset
775: functions.
776: Paul Clifford contributed an assembly strlen.S for ARM and fixed
777: several bugs.
778: Fixed ppc/setjmp and mips/pipe.
779: Olaf contributed a new sparc unified syscall.
780:
781: 0.6.4:
782: declared is* static inline in getservent.
783: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
784: changed strlen to return 0 when passed NULL.
785: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
786: Scientist who actually implemented this without access to a MIPS
787: box, just from reading the architecture manual. And it worked out
788: of the box.
789: started a set of system includes, mainly so that I can use lcc and
790: my alpha-linux cross compiler (which is unable to cross-compile
791: glibc). diet libc can now be compiled without any include files
792: from a normal libc. The includes do declare more than diet libc
793: currently delivers and they are still far from complete for real
794: applications.
795: I will only add assembly versions that are smaller _and_ faster than
796: the C version. Larger routines are only accepted if they are called
797: very often and are substantially faster.
798: added i386 assembly strchr, which is smaller and faster than the old
799: version. It is, however, larger than the version contributed by
800: proton (thanks, anyway).
801: added i386 strlen (31% faster, 14% smaller)
802: "make t" will now create a map file called "mapfile".
803:
804: 0.6.3:
805: added sys_errlist, strerror and perror
806: added isblank
807: added atol
808:
809: 0.6.2:
810: mmap for ARM didn't compile. Thanks, Paul!
811:
812: 0.6.1:
813: split mmap into the architecture specific subdirectories.
814: getenv now copes with environ==NULL, thanks Paul Clifford.
815: Paul also contributed a smaller ARM startup code.
816:
817: 0.6:
818: strcat returned the wrong result. Thanks, Dietz Pröpper.
819: strtod now understands a negative exponent (oops, thanks Bertram Barth)
820: Port to arm-linux-gnu, but on the Netwinder I use for testing the
821: __dtostr does not work (I have no idea why!)
822: The MIPS port now uses (much smaller) non-PIC code. That means that
823: the applications you link against diet libc also have to be compiled
824: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
825: Thanks to Ralf Bächle for helping me with this!
826: I made subdirectories for the architectures and use VPATH to override
827: VPATH so that make finds the source file automatically. That should
828: simplify the sources greatly.
829: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
830: ARM and MIPS now also have setjmp and longjmp
831: "compile" and "load" are now make targets. Use them for djb programs.
832: added contrib/elftrunc.c which will remove unnecessary ELF headers.
833: Again, contributed from Olaf. Great work!
834:
835: 0.5.12:
836: printf also does signed numbers.
837: If you don't use atexit, dietlibc now does not link exit, only _exit.
838: *printf now correctly returns the number of bytes written.
839: Olaf contributed experimental sscanf and vsscanf implementations.
840: If passed NULL as buffer, snprintf will not write anything but still
841: return the number of bytes it would have written.
842: Initial MIPS port! (Oh, the agony!)
843: No setjmp and longjmp support yet! Please contribute!
844: I even implemented unified syscalls for MIPS. Still, MIPS code is
845: almost twice the size of SPARC code. If anyone knows why: please
846: tell me!
847:
848: 0.5.11:
849: I implemented new unified syscalls for x86, sparc and ppc, this time based
850: on .s files and not .c files, and I moved the syscalls into
851: subdirectores to clean the dietlibc sources up a little.
852: A binary consisting of printf("%s is %d\n","olaf",23) is now
853: 2864 bytes on sparc
854: 2488 bytes on intel
855: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
856: to make a few more applications work.
857: Olaf Dreesen also implemented some unified syscall stuff for x86.
858: He discovered that with our unified syscall interface it actually
859: costs <10 bytes total to make all system calls thread safe!
860: I implemented atexit() (can register up to 4 callbacks).
861: I implemented strtod and __dtostr (the opposite). Now we can add
862: floating point support to vsnprintf and sscanf!
863:
864: 0.5.10:
865: I actually saw that I can not only merge the errno handling code of
866: the system calls on x86, I can also merge the rest (including the
867: arguments) except for setting the system call number. All those
868: system calls are now just a jump to a unified system call handler.
869: I got rid of x86openclose again. The savings are substantial:
870: chown from embutils went from 7664 to 7184 bytes!
871: If I'd move the system call wrappers to assembly language, I could
872: even reduce the alignment (does not matter since it's just a jump
873: anyway) and get rid of the "ret" behind each jump (one byte per
874: system call!)
875:
876: 0.5.9:
877: added memchr, strpbrk, strstr, strtol, isspace (hehe)
878: fixed strdup
879: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
880: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
881: (no signed integers, only strings and unsigned integers (but
882: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
883: that code must be wonderful, I don't understand it at all *bg*)
884: Olaf's printf does understand padding like in "%08d" and "%8d" and
885: automatically pads pointers with '0'.
886: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
887: Thanks to proton for inspiration on this.
888: The new x86 start code also does not reference exit any more, thus saving
889: 64 bytes for executables that don't call exit explicitly.
890: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
891: Moved errno and environ to start.S, saving no byte binary size but
892: speeding up compilation and slightly shortening dietlibc.a ;-)
893: For x86: joined open and close into one assembler file, sharing the
894: errno handling. This is a feasibility test and it actually saves a
895: few bytes. I think I will reimplement the _syscall[1-6] macros on
896: all platforms now to share the errno handling code for them.
897:
898: 0.5.8:
899: fixed strchr to be able to look for 0.
900:
901: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
902: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
903: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
904: contributed by Olaf Dreesen)
905:
906: added execvp, getcwd
907:
908: fixed __xmknod
909:
910: Note: can it be that the ftw interface really is so broken that I
911: cannot implement it without having to implement some searching data
912: structure? I included an experimental ftw implementation that will
913: not follow symlinks.
914:
915: 0.5.7:
916: oops, if_nametoindex was broken!
917:
918: 0.5.6:
919: ported to ppc-linux.
920: fixed i386 sigsetjmp (I mistyped the function name)
921: included sigjmp.c
922:
923: 0.5.5:
924: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
925: actually, it wasn't fork that wasn't working for sparc, it was pipe.
926: I fixed it now.
927: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
928: fixed readdir to use getdents and not the intel inline asm
929:
930: 0.5.4:
931: ported to sparclinux (sparc32 only). Beware: does not work yet.
932: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
933:
934: 0.5.3:
935: added tcsetattr and getenv to compile e3
936:
937: 0.5.2:
938: added vhangup, tcgetattr, isatty and memcmp for fgetty
939: (http://www.fefe.de/fgetty/)
940: added localtime from uC-libc.
941:
942: 0.5.1:
943: stat and friends actually work now. Yuck! Another case of
944: translation between kernel and userland. Why can't the kernel
945: people and the libc people simply agree on a standard?
946: removed many unnecessary includes to speed up compilation.
947: added -fomit-frame-pointer and i386 compilation target to reduce code size.
948: inlined socketcall to reduce code size.
949: "load" and "compile" are examples for djb code.
950:
951: 0.5:
952: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
953: each object file is now treated with "strip -x -R .note -R .comment"
954: split each system call into a separate object file
955: added ntohs, htons, alarm, if_indextoname and if_nametoindex
956:
957: 0.4.1:
958: oops, the strchr implementation was wrong. Thanks Jens Laas!
959:
960: 0.4:
961: copied opendir and friends from uC-libc.
962: added getservent and getservby* in gerservent.c
963:
964: 0.3:
965: remove readdir system call
966: added getdents system call
967: added getpwnam/getpwuid implementation in getpwnam.c
968: added a few string functions (in str*.c)
969:
