69: the diet libc already supports it! Amazing ;-)
70: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 71: Andre sent a patch to add ARM profiling. He says it does not work

110: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 111: Thomas also sent me profiling support (so far only on x86, but
112: profiling/PORTING describes what needs to be done for other
113: architectures)!
1.272 fefe 114: add contrib/dprof.c, also from Thomas.
1.269 fefe 115: Andreas Krennmair sent a patch to add the BSD regex interface to
116: libcompat

1.277 fefe 121: fix some nasty regular expression bugs
122: write a stupid malloc checker (contrib/debug-realloc.c) to help me

1.278 fefe 124: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 125: fix DNS domain search
1.280 fefe 126: i386 memccpy exchanged esi and edi :-( I should do more checks before

1.244 fefe 129: 0.16:
130: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 131: Andre found two very embarassing bugs in my four lines of md5 glue.
132: I need to get more sleep.
1.247 fefe 133: Thanks Ogrisegg found that ptrace does not work as documented and
134: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 135: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
136: fix ptrace.h for S/390 and ARM
137: provide a PORTING document so we don't lose track of which file need
138: to be touched to port the diet libc to a new platform.
1.249 fefe 139: remove a few warnings
140: provide a prototype for usleep.
1.250 fefe 141: make __dtostr work on ARM by using long instead of long long.
142: Idea by Dirk Engling.

148: create libcompat.a (and move daemon to it)
1.255 fefe 149: add getdelim and getline
150: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 151: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 152: Olaf: fixed *scanf familie. It hadn't wored with "long long".

1.244 fefe 160:
1.224 fefe 161: 0.15:
1.225 fefe 162: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 163: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 164: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
165: thread-safe!
1.228 fefe 166: remove vfork and add alarm to dynamic syscalls.
167: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 168: The MD5 code generated unaligned accesses when passed an unaligned
169: pointer on little endian ARM and MIPS.
170: MIPS unified syscall didn't compile anymore.
171: Put up new mipsel target to cross compile for little endian mips.
172: The mips target will again explicitly set endianness to big endian.
173: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 174: Duh, when we removed return0, we broke tzset when the time zone parser
175: was disabled. Uwe Ohse noticed this. Thanks!
176: Fix gethostbyname to match host names case insensitively in /etc/hosts.
177: Oops, this was reported 6 weeks ago but I overlooked the email.
178: Thanks, Denis Rachal!
1.231 fefe 179: vsnprintf's zero termination was broken.
1.233 fefe 180: Uwe Ohse found a few more bugs:
181: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
182: does it correctly.
183: Make inet_aton use strtoul instead of strtol
184: fdopen would close the file descriptor if it could not malloc the
185: buffer.
186: strftime updates.
187: Make _FILE_OFFSET_BITS includes -Wundef clean
188: Andre found a typo in endian.h for big endian mips
1.234 fefe 189: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 190: strstr(whatever,"") returned NULL, not whatever. Found by a new test
191: suite entry for strstr that I wrote.
1.245 fefe 192: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 193: add <asm/sigcontext.h> for profiling support.
194: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 195: an i386 assembler getenv implementation (roughly half the size)
196: add grantpt, ptsname, unlockpt
1.236 fefe 197: add a getenv test suite entry.
1.238 fefe 198: Andre contributed an ARM assembler md5 implementation and he fixed mmap
199: on ARM.
200: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 201: getservent_r did not parse lines without aliases. Thanks, Jaroslav
202: Macodiseas!
1.240 fefe 203: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 204: removed annoying -Wconversion gcc switch
1.242 fefe 205: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 206: Kurt Garloff sent these diffs:
207: add fdatasync (and make it a pthread cancellation point)
208: numerous alpha issues, like using .quad instead of .long for
209: offsets, change strip to -strip in Makefile (so a failing strip does
210: not abort the make), try to be more friendly to the gcc 2.96 that
211: SuSE 7.1 AXP ships with.
1.224 fefe 212:
1.209 fefe 213: 0.14:
1.224 fefe 214: fix brk again (missing __brk, trivial oversight)
1.210 fefe 215: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
216: Thomas Ogrisegg!
1.211 fefe 217: Thomas also contributed a PA-RISC port including testandset, so
218: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 219: made the fake locale more believable.
220: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 221: moved _exit into the unified syscall on x86.
1.214 fefe 222: Uwe Ohse found many more bugs:
223: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
224: liblatin1 was more or less completely broken if you gave it chars as
225: arguments, not ints (signedness). execvp had a buffer overflow in
226: case a PATH element exceeded PATH_MAX, but it's not a security
227: problem since setuid programs need to set their path to some known
228: value anyway.
1.219 fefe 229: hasmntopt did not work with foo=bar style options
1.217 fefe 230: Uwe also improved ftw's stack usage.
1.214 fefe 231: Put movl instead of popl rationale in comment in i386/unified.S since
232: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 233: I discovered __attribute__((malloc)) and started using it. For gcc 3,
234: it improves the optimizer when functions return malloced pointers.
1.216 fefe 235: Steven Rostedt pointed out that my setvbuf was broken with regard to
236: size==0 and sent a patch to fix it.
1.218 fefe 237: Thomas Ogrisegg made setenv smaller.
1.220 olaf 238: Olaf: implemented the parisc clone and an atomic testandset, modified the
239: libpthread to respect the parisc UPgrowing stack. still non functional,
240: because the unified syscall uses errno :(
1.221 fefe 241: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 242: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
243: don't write anything which was no longer the case. It also
244: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 245: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 246:
1.193 fefe 247: 0.13:
1.194 fefe 248: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 249: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 250: Olaf: port to S/390!
1.196 leitner 251: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 252: res_query did not initialize last
1.199 fefe 253: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 254: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 255: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 256: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 257: rewrote __dtostr (it also has one more argument now)
1.205 fefe 258: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 259: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
260: fix strncat for the case where n == 0 (security implications?)
261: fix bsearch (it didn't find the very last element in the array, same
262: bug in both the C and the i386 assembly version).
1.205 fefe 263: fixed FNM_PATHNAME in fnmatch
1.204 fefe 264: fix brk (the syscall was documented incorrectly in the Linux man page)
265: Thanks, Thomas Ogrisegg!
1.205 fefe 266: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 267: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 268: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 269:
1.164 fefe 270: 0.12:
271: more contributions from Frank Klemm.
1.165 fefe 272: iconv can now do UCS-2, too.
1.167 fefe 273: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 274: Lots of bug fixes, and several more i386 specific versions of common
275: routines to make them smaller.
1.168 fefe 276: add memmem (a GNU extension that looks useful)
1.170 fefe 277: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 278: add pivot_root syscall, %n for *scanf.
1.169 fefe 279: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 280: add Frank Klemm's optimized md5
1.172 fefe 281: add -Os option to diet (see diet.1).
1.173 fefe 282: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 283: add 32-bit uid/gid syscalls.
1.175 fefe 284: add rand48 (thanks, Johannes Kloos)
1.176 fefe 285: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 286: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
287: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
288: fix gethostent alias list termination. Major oops.
1.178 fefe 289: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 290: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 291: DNS will now properly signal errors and set h_errno.
292: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 293: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
294: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
295: external reference to a symbol that is only in the diet libc. So,
296: when you accidentally link a diet libc compiled object file against
297: glibc, the linker will barf. This will bloat your object files, but
298: you can remove all the references with "strip -R .note" from
299: the binaries in the end (which you should do anyway).
1.182 fefe 300: fix ARM unified syscall (select did not work).
1.183 fefe 301: add getpwent_r ala glibc and replace getpwent
302: do the same for getgrent and getspent
303: remove entlib (new code is smaller)
1.184 fefe 304: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 305: add getpwnam_r and getpwuid_r
1.186 fefe 306: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 307: Olaf muddled with the dynamic linker. It's a clean-room
308: implementation in the sense that it once worked for Olaf in a clean
309: room ;)
1.188 fefe 310: add if_nameindex and if_freenameindex.
311: fixed arm unified syscalls to work with current binutils (; is no
312: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 313: changed all st_[cma]time types to signed long so comparisons against
314: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 315: fixed two bugs regarding ungetc.
316: add getusershell, setusershell, endusershell (for vs_ftpd)
317: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 318: fixed strftime (was completely hosed)
1.192 fefe 319: added real make install target
1.164 fefe 320:
1.115 fefe 321: 0.11:
322: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 323: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 324: add floor, ceil and memchr prototypes.
325: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 326: cleaner errno vs __errno_location handling
327: add placeholder iconv (iconv_open will always return EINVAL)
328: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
329: initialization of getaddrinfo.
1.119 fefe 330: fix vsnprintf %X (printed lower case)
1.120 fefe 331: I wrote a new getopt. It appears to actually work (it is POSIX
332: compliant, it does not sort argv like the GNU version) and is only
333: a little over 300 bytes on x86.
1.121 fefe 334: Guillaume Cottenceau just wrote me that strncat should be even more
335: broken than it already is: it should append n bytes AND THEN \0!
336: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 337: Fix regexec offset return. autoconf now believes that diet libc has
338: POSIX regular expressions.
1.123 fefe 339: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 340: Fix regular expression match for x* when there is no x at all.
1.125 fefe 341: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 342: Add %h to vsnprintf.
1.127 fefe 343: Add FAQ.
1.128 fefe 344: Make %h work for signed numbers and add %hh to vsnprintf.
345: initgroups ignored the group argument :-(
346: remove printf references and nested functions from glob.
1.129 fefe 347: added an errno in libpthread that will display a prominent linker
348: warning.
1.131 fefe 349: started getting rid of kernel headers. Big task! :-(
1.130 fefe 350: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 351: Olaf: added a lot of code in libdl (not yet complete), changed the
352: startup code to make it work with his libdl and ld.so (needs still work
353: too)
1.134 fefe 354: __dns_readstartfiles only took the first domain or search path.
355: Thanks, Anthony de Boer
1.133 olaf 356: Olaf: added clone and a new unified_syscall for PowerPC
357: also dynlinker is now available (i386 only at this time)
1.135 fefe 358: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 359: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 360: fixed word delimiters in regex (they looked for space, i.e. "," did
361: not work as delimiter)
1.138 fefe 362: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 363: added mkdtemp.
1.142 fefe 364: Uwe Ohse reported all of the following bugs:
365: ttyname should return 0 if !isatty.
366: realpath returns NULL if "." cannot be opened
367: putenv erroneously accepted (and mishandled) entries without "=".
368: popen returned 255 instead of 127 if /bin/sh could not be run.
369: fgetc did not set the internal EOF indicator on EOF.
370: bsearch contained an assumption about integer arithmetic overflow
371: behavior.
372: system did not set SIGCHLD and thus contained a race.
373: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 374: daemon did not check whether open returns an fd below 3
375: perror did not save errno.
1.144 olaf 376: Olaf: Peter Jones reported some problems with perror; strerror had the
377: same problem.
378: Peter also posted a patch to atexit/exit. With some modifications it is
379: now implemented.
1.145 fefe 380: Unbuffered stdio and ungetc can no longer be disabled. I will try to
381: implement part of it using ELF weak symbols.
1.146 fefe 382: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 383: Added overflow handling for strtoul and strtol.
1.149 fefe 384: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
385: it before falling back to DNS if enabled.
1.150 fefe 386: Added a littie backwards compatibility cruft for gpm (man, do these
387: sources stink!)
1.151 fefe 388: Added openpty.
1.152 fefe 389: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 390: Fix fseek return value.
1.155 fefe 391: Add dirname and basename.
1.156 fefe 392: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 393: Fixed getservent (did not allow _ and - in the aliases).
394: Thanks, Oden Eriksson
1.158 fefe 395: Added a float.h so configure believes we have ANSI header files.
396: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 397: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 398: scanf and printf function implementations
1.160 fefe 399: Imported a few more functions and optimizations from Frank Klemm (he
400: also rewrote dtostr to have more precision)
1.161 olaf 401: Olaf: checked in a new sig* function family (based on rt_sig*).
402: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 403: Made rudimentary iconv that can convert back and forth between
404: iso-8859-1, utf-8 and ucs-4 (for debugging).
405: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 406:
1.74 fefe 407: 0.10:
408: update getpagesize.
409: add personality.
1.75 fefe 410: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 411: add putchar (apparently arm-linux-gcc will substitute printf("\n")
412: with putchar('\n') behind your back...?!
1.77 fefe 413: import include/scsi/ from glibc.
1.78 fefe 414: add iopl.
1.80 fefe 415: add execl and sigdelset prototypes.
416: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 417: add RPC headers (no code yet).
1.82 fefe 418: add mlockall, munlockall
1.83 fefe 419: make "diet gcc foo.c" work.
420: added Sun RPC code and removed as many warnings as possible in a
421: heroic act of self-mutilation.
422: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 423: added getpass. mount from util-linux actually compiles now!
424: fix the sig*set routines. mount actually works now *bg*
425: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 426: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 427: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 428: add res_init.
429: add asprintf (ugh, what an ugly function).
1.89 fefe 430: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 431: add ut_name alias to ut_host in struct utmp.
432: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 433: add sysinfo, recvmsg, sendmsg.
1.93 fefe 434: add endmntent, getmntent, setmntent.
1.94 fefe 435: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 436: add setenv.
437: remove __restrict from mntent.h, add __restrict__ removal alias for
438: older gcc versions in sys/cdefs.h.
439: add rlim_t, sig_atomic_t declarations.
440: add sigsetjmp #define for __sigsetjmp (oops).
441: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 442: add a gruesome hack to printf floating point to accept %f and kludge
443: together support for %.2f. Don't look at the code, please!
1.98 fefe 444: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 445: imported fix for entlib by Jeff Garzik.
1.100 fefe 446: add glob implementation from Guillaume Cottenceau (Thanks!!)
447: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 448: add REG_ICASE and word start/end handling to my regular expressions.
449: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 450: wrap getcwd to comply to man page (the syscall returns the number of
451: bytes, not the buffer)
452: add realpath.
1.103 fefe 453: fix vfprintf.
1.104 fefe 454: fix *scanf %s zero termination.
455: add abs, labs, llabs.
1.105 fefe 456: add <sys/io.h>, ioperm syscall.
457: add flock to <sys/file.h>
1.106 fefe 458: fixes to bsearch and the regular expressions.
1.107 fefe 459: add fake herror.
1.108 fefe 460: add scandir and alphasort.
1.109 fefe 461: add killpg
1.110 fefe 462: implemented a gross hack to make libpthread compile when
463: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 464: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 465: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 466: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
467: for sending a patch.
1.114 fefe 468: add getserv*.
469: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
470: "search" from resolv.conf.
1.74 fefe 471:
1.73 fefe 472: 0.9:
1.65 fefe 473: fixed initgroups (oops)
1.66 fefe 474: Cleanup appending file open for stdio (thanks, James Antill)
475: imported vfprintf fix from James Antill.
1.67 fefe 476: add fnmatch
477: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 478: Olaf added character classes to *scanf.
1.69 fefe 479: Put object and library files into a separate directory (bin-$ARCH).
480: Add "cross" make target to make all architectures.
481: Add "diet" program and man page.
1.70 fefe 482: Add getgrnam, getgrgid
1.71 fefe 483: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 484: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 485:
1.64 fefe 486: 0.8:
1.34 fefe 487: vsnprintf(0,...) estimated the length of strings with a padding width
488: incorrectly.
1.35 fefe 489: new reboot() from Olaf.
1.36 fefe 490: added prototypes for getsockopt and setsockopt.
1.39 fefe 491: added experimental sem* and shm*
1.38 fefe 492: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 493: added setvbuf (only changes mode, not buffer)
1.41 fefe 494: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
495: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 496: added qsort() and bsearch(). Benchmark on 1000 random ints:
497: glibc: 679414 cycles qsort and 3352 cycles bsearch
498: diet libc: 300010 cycles qsort, 553 cycles bsearch
499: I have no idea why glibc is so slow.
1.43 fefe 500: added __isnan (references by libm.a from glibc).
501: added popen() and pclose(). Now the diet libc can link slsh (from
502: S-Lang!)
1.44 fefe 503: corrected usleep. It was more of an msleep until now.
1.45 fefe 504: corrected __dtostr (it looped when trying to format "0.0").
505: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 506: added ungetc (does it work?)
1.47 fefe 507: added inet_aton (yuck!)
1.50 fefe 508: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 509: added h_errno and __h_errno_location
510: added inet_ntoa
1.49 fefe 511: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 512: add bcopy, index, rindex macros
513: add isgraph and isxdigit
1.52 fefe 514: add strftime (ugh!!!)
1.53 olaf 515: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 516: Jeff Garzik contributed a spec file. I put it in contrib and hope
517: everbody knows what to do with it...
518: Olaf checked in a ton of libpthread stuff.
1.55 fefe 519: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 520: add large file backwards compatibility support (so gzip will run on
521: kernel 2.2 and 2.0)
1.57 fefe 522: added shutdown
1.58 fefe 523: added nice
524: added pseudo-locale support for is* (they are now weak aliases,
525: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
526: overwrite the default is* functions.
1.59 fefe 527: added liblatin1.a
1.60 fefe 528: added tzfile implementation (does it work for anyone else?)
1.61 fefe 529: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 530: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
531: Thanks!
1.63 fefe 532: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 533:
1.21 fefe 534: 0.7.2:
535: added several prototypes to already implemented functions and
536: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 537: added prototypes for process group and dup syscalls. Thanks to
538: Abraham again. He also contributed an implementation for daemon(),
539: an ugly BSD hack. I decided to diversify the lib/ directory a
540: little and now created a libugly/ directory for stuff like system()
541: and daemon() ;-)
542: added libstdio and moved all that stdio crap from lib/ there. The
543: idea is to start separating now what we will separate for shared
544: libraries anyway.
1.26 fefe 545: optimized x86 unified-syscall by Olaf.
1.27 fefe 546: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
547: limits.h instead)
548: added remove.c and enough cruft to limits.h to make it compile lzo,
549: lzop and bzip2.
1.28 fefe 550: added mktime, asctime_r, asctime and ctime (needed for gzip).
551: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 552: format some day (man tzfile, ugh!) :-(
1.29 fefe 553: added unlink prototype to unistd.h.
554: added gmtime and gmtime_r.
1.31 fefe 555: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 556: removed readdir glibc compatibility cruft.
1.31 fefe 557: removed stat glibc compatibility cruft.
1.32 fefe 558: oops, my fread was broken for pipes.
1.33 fefe 559: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 560:
1.9 fefe 561: 0.7.1:
1.11 fefe 562: optimized away the static arrays from __ltostr and __lltostr.
563: optimized away the static arrays (and more!) from strtoul and strtoull.
564: added system (by Olaf).
1.12 fefe 565: added tolower and toupper
1.13 fefe 566: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 567: added clone for mips (by Olaf).
568: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 569: added pause for all (by Olaf).
1.17 fefe 570: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 571: added isupper and islower.
572: added putc and putchar as macros.
1.17 fefe 573: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
574: insightful discussions and patches I partially used for the last three)
1.18 fefe 575: added getpriority and setpriority (also by Abraham)
1.19 fefe 576: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 577: oi, setjmp and longjmp were broken on other platforms, too!
578: Thanks to Sébastien Côté for reporting this.
1.9 fefe 579:
580: 0.7:
1.6 olaf 581: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 582: Initial dynamic loading glue for i386, also by Olaf.
583: We don't have a dynamic loader yet, so this is not yet usable.
584: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
585: vsprintf, writev, all by Olaf.
1.2 fefe 586: imported readdir fix from Guillaume. Mhh, can the kernel interface
587: really be this broken?
1.3 fefe 588: Found a kludgy way to detect whether the kernel includes define struct
589: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
590: not work for you, please tell me!
1.4 fefe 591: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 592: Fixed stdio line buffering. The code was already there but I forgot
593: to mark stdio and stdout as line buffered. This should really be
594: done dynamically using isatty, though.
1.8 fefe 595: Removed superfluous "if (1)" in execvp.c
1.1 cvs 596:
597: 0.6.14:
598: *scanf did not append the 0 byte for %s.
599: added creat and changed creat to call open directly instead of open64.
600: did for fread what 0.6.10 did for fwrite.
601: repaired buffered stdio a little (line buffering is still not
602: supported).
603: [All of these bugs have been reported by Guillaume. Thanks!]
604: added __pure__ to strchr and strrchr in <string.h>
605:
606: 0.6.13:
607: included COPYING to make clear that the diet libc is covered by the
608: GNU General Public License (and _not_ the LGPL). That means that
609: you need to obtain a license from me if you want to use the diet
610: libc in a proprietary program that you want to distribute.
611: The x86 unified syscall swapped arguments #4 and #5 and noone
612: noticed until now! Thanks to Guillaume Cottenceau for reporting
613: this!
614: The malloc had a subtle bug with small allocations that could cause
615: segfault. Guillaume reported it, Olaf fixed it.
616:
617: 0.6.12:
618: added assert, statfs and fstatfs
619: added include/net/if.h so fget compiles again.
620:
621: 0.6.11:
622: added putenv.
623:
624: 0.6.10:
625: fixed fwrite. It returned the number of bytes written, not the number
626: of records. Thanks to Albert D. Cahalan for pointing this out.
627: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
628: added brk and sbrk. harold@nb.com.sg made me do it.
629:
630: 0.6.9:
631: fixed execvp not to return on ENOENT
632: did for {open|read|close|seek|tell}dir what I did for stat before.
633: The glibc compatibility part is currently non-functional.
634: fixed white space handling in sscanf " (" would not match " (".
635: fixed printf to accept 'l' flag.
636: fixed getpwuid (ignored last line)
637:
638: 0.6.8:
639: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
640: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
641: added strlcpy and strlcat from OpenBSD.
642: added stat64, fstat64 and lstat64.
643: added endian.h and made ending of strlen.c endianness-aware
644: added string routines size tweak to dietfeatures.h. Most of the
645: string routines have been unrolled. This is up to three times as
646: fast but creates up to three times larger code. Now you can disable
647: the unrolling.
648: added sendfile.
649: I also added pread. It works on x86 and sparc but not on ppc and mips.
650: I have no idea what's going on. strace disagrees with the kernel.
651: Can anyone help? I asked the Linux kernel mailing list for help, too.
652: added a few aliases of the type __libc_open for open. nm on
653: libpthreads.so indicates that we will need them.
654:
655: 0.6.7:
656: the sources now compile without warnings with -Wall.
657: printf now prints "(null)" when %s is passed NULL. This can be
658: removed with WANT_NULL_PRINTF in dietfeatures.h
659: added vfprintf, execl, ttyname.
660: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
661: __dietfstat so they can use the normal kernel struct stat.
662: stat, lstat and fstat are now C wrappers that convert to the glibc
663: struct stat. So we can avoid that overhead for programs that use
664: dietlibc headers.
665:
666: 0.6.6:
667: changed the Makefiles so you can now set CFLAGS on the command line
668: added memccmp (analogous to memccpy) and strncmp.
669: Olaf fixed another bug in the sparc unified syscall.
670: Paul Clifford contributed a C version of his strlen.S that is much
671: more efficient than the previous strlen on all platforms! It also
672: looks like technology from Roswell. ;-}
673: added a "real" stdio. Well, almost. Please contribute!
674: added dietfeatures.h so you can remove features you don't need.
675: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
676: stdio now works with simple programs and minigzip from libz.
677: stdio uses some major trickery to avoid linking the stdio, stderr and
678: stdout (and reserving space for them) when they are not used.
679:
680: 0.6.5:
681: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
682: most of them bugs in the new header files, but also missing sigset
683: functions.
684: Paul Clifford contributed an assembly strlen.S for ARM and fixed
685: several bugs.
686: Fixed ppc/setjmp and mips/pipe.
687: Olaf contributed a new sparc unified syscall.
688:
689: 0.6.4:
690: declared is* static inline in getservent.
691: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
692: changed strlen to return 0 when passed NULL.
693: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
694: Scientist who actually implemented this without access to a MIPS
695: box, just from reading the architecture manual. And it worked out
696: of the box.
697: started a set of system includes, mainly so that I can use lcc and
698: my alpha-linux cross compiler (which is unable to cross-compile
699: glibc). diet libc can now be compiled without any include files
700: from a normal libc. The includes do declare more than diet libc
701: currently delivers and they are still far from complete for real
702: applications.
703: I will only add assembly versions that are smaller _and_ faster than
704: the C version. Larger routines are only accepted if they are called
705: very often and are substantially faster.
706: added i386 assembly strchr, which is smaller and faster than the old
707: version. It is, however, larger than the version contributed by
708: proton (thanks, anyway).
709: added i386 strlen (31% faster, 14% smaller)
710: "make t" will now create a map file called "mapfile".
711:
712: 0.6.3:
713: added sys_errlist, strerror and perror
714: added isblank
715: added atol
716:
717: 0.6.2:
718: mmap for ARM didn't compile. Thanks, Paul!
719:
720: 0.6.1:
721: split mmap into the architecture specific subdirectories.
722: getenv now copes with environ==NULL, thanks Paul Clifford.
723: Paul also contributed a smaller ARM startup code.
724:
725: 0.6:
726: strcat returned the wrong result. Thanks, Dietz Pröpper.
727: strtod now understands a negative exponent (oops, thanks Bertram Barth)
728: Port to arm-linux-gnu, but on the Netwinder I use for testing the
729: __dtostr does not work (I have no idea why!)
730: The MIPS port now uses (much smaller) non-PIC code. That means that
731: the applications you link against diet libc also have to be compiled
732: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
733: Thanks to Ralf Bächle for helping me with this!
734: I made subdirectories for the architectures and use VPATH to override
735: VPATH so that make finds the source file automatically. That should
736: simplify the sources greatly.
737: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
738: ARM and MIPS now also have setjmp and longjmp
739: "compile" and "load" are now make targets. Use them for djb programs.
740: added contrib/elftrunc.c which will remove unnecessary ELF headers.
741: Again, contributed from Olaf. Great work!
742:
743: 0.5.12:
744: printf also does signed numbers.
745: If you don't use atexit, dietlibc now does not link exit, only _exit.
746: *printf now correctly returns the number of bytes written.
747: Olaf contributed experimental sscanf and vsscanf implementations.
748: If passed NULL as buffer, snprintf will not write anything but still
749: return the number of bytes it would have written.
750: Initial MIPS port! (Oh, the agony!)
751: No setjmp and longjmp support yet! Please contribute!
752: I even implemented unified syscalls for MIPS. Still, MIPS code is
753: almost twice the size of SPARC code. If anyone knows why: please
754: tell me!
755:
756: 0.5.11:
757: I implemented new unified syscalls for x86, sparc and ppc, this time based
758: on .s files and not .c files, and I moved the syscalls into
759: subdirectores to clean the dietlibc sources up a little.
760: A binary consisting of printf("%s is %d\n","olaf",23) is now
761: 2864 bytes on sparc
762: 2488 bytes on intel
763: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
764: to make a few more applications work.
765: Olaf Dreesen also implemented some unified syscall stuff for x86.
766: He discovered that with our unified syscall interface it actually
767: costs <10 bytes total to make all system calls thread safe!
768: I implemented atexit() (can register up to 4 callbacks).
769: I implemented strtod and __dtostr (the opposite). Now we can add
770: floating point support to vsnprintf and sscanf!
771:
772: 0.5.10:
773: I actually saw that I can not only merge the errno handling code of
774: the system calls on x86, I can also merge the rest (including the
775: arguments) except for setting the system call number. All those
776: system calls are now just a jump to a unified system call handler.
777: I got rid of x86openclose again. The savings are substantial:
778: chown from embutils went from 7664 to 7184 bytes!
779: If I'd move the system call wrappers to assembly language, I could
780: even reduce the alignment (does not matter since it's just a jump
781: anyway) and get rid of the "ret" behind each jump (one byte per
782: system call!)
783:
784: 0.5.9:
785: added memchr, strpbrk, strstr, strtol, isspace (hehe)
786: fixed strdup
787: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
788: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
789: (no signed integers, only strings and unsigned integers (but
790: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
791: that code must be wonderful, I don't understand it at all *bg*)
792: Olaf's printf does understand padding like in "%08d" and "%8d" and
793: automatically pads pointers with '0'.
794: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
795: Thanks to proton for inspiration on this.
796: The new x86 start code also does not reference exit any more, thus saving
797: 64 bytes for executables that don't call exit explicitly.
798: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
799: Moved errno and environ to start.S, saving no byte binary size but
800: speeding up compilation and slightly shortening dietlibc.a ;-)
801: For x86: joined open and close into one assembler file, sharing the
802: errno handling. This is a feasibility test and it actually saves a
803: few bytes. I think I will reimplement the _syscall[1-6] macros on
804: all platforms now to share the errno handling code for them.
805:
806: 0.5.8:
807: fixed strchr to be able to look for 0.
808:
809: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
810: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
811: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
812: contributed by Olaf Dreesen)
813:
814: added execvp, getcwd
815:
816: fixed __xmknod
817:
818: Note: can it be that the ftw interface really is so broken that I
819: cannot implement it without having to implement some searching data
820: structure? I included an experimental ftw implementation that will
821: not follow symlinks.
822:
823: 0.5.7:
824: oops, if_nametoindex was broken!
825:
826: 0.5.6:
827: ported to ppc-linux.
828: fixed i386 sigsetjmp (I mistyped the function name)
829: included sigjmp.c
830:
831: 0.5.5:
832: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
833: actually, it wasn't fork that wasn't working for sparc, it was pipe.
834: I fixed it now.
835: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
836: fixed readdir to use getdents and not the intel inline asm
837:
838: 0.5.4:
839: ported to sparclinux (sparc32 only). Beware: does not work yet.
840: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
841:
842: 0.5.3:
843: added tcsetattr and getenv to compile e3
844:
845: 0.5.2:
846: added vhangup, tcgetattr, isatty and memcmp for fgetty
847: (http://www.fefe.de/fgetty/)
848: added localtime from uC-libc.
849:
850: 0.5.1:
851: stat and friends actually work now. Yuck! Another case of
852: translation between kernel and userland. Why can't the kernel
853: people and the libc people simply agree on a standard?
854: removed many unnecessary includes to speed up compilation.
855: added -fomit-frame-pointer and i386 compilation target to reduce code size.
856: inlined socketcall to reduce code size.
857: "load" and "compile" are examples for djb code.
858:
859: 0.5:
860: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
861: each object file is now treated with "strip -x -R .note -R .comment"
862: split each system call into a separate object file
863: added ntohs, htons, alarm, if_indextoname and if_nametoindex
864:
865: 0.4.1:
866: oops, the strchr implementation was wrong. Thanks Jens Laas!
867:
868: 0.4:
869: copied opendir and friends from uC-libc.
870: added getservent and getservby* in gerservent.c
871:
872: 0.3:
873: remove readdir system call
874: added getdents system call
875: added getpwnam/getpwuid implementation in getpwnam.c
876: added a few string functions (in str*.c)
