1.352 fefe 15: fix unified x86_64 unified syscall 64-bit return value issue (Gwenole)
1.353 fefe 16: the getdents64 emulation was broken and repairing it opened a can of
17: worms. So I ripped it out. I also changed the readdir64 emulation
18: to work if there is no getdents64.
1.354 fefe 19: fix ia64 start.S (Thanks to Volker Birk for an account on his ia64 box)
1.355 fefe 20: many ia64 fixes (waitpid, nice, fork, vfork, time, utime ...)
1.356 fefe 21: More fixes from Gwenole (printf %p only printed the last 32 bits, I
22: botched the getdents64 #ifdefs, we violated the x86_64 ABI)
1.357 fefe 23: change signal() to do as glibc does

1.360 fefe 27: the new x86 syscall numbers exceed 255, breaking our %al optimization
28: I worked around it with conditional assembly in cpp macros. Ugh.
1.361 fefe 29: more MIPS fixes (the stoned MIPS ABI for restartable syscalls expects
30: the instruction before the syscall to be a load immediate)
31: fix fread() from a pipe (oops, tried to lseek)
1.362 fefe 32: #define _POSIX_VDISABLE in termios.h (Laurent Bercot)
1.363 fefe 33: two *printf fixes (Gernot Tenchio)

43: use -G 8 on MIPS to reduce code size (Johannes Stezenbach)
1.328 fefe 44: add munlock (Jens Låås)
1.330 fefe 45: argh, atexit fell victim to bit rot (or maybe Olaf)
1.331 fefe 46: add WANT_INET_ADDR_DNS to make gethostbyname not look up IP numbers
47: but use them to fill in the struct hostent directly.
1.332 olaf 48: signal is now a correct signal (Olaf)
1.333 fefe 49: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
50: the built-in defaults.
1.334 fefe 51: add file "SECURITY". I will document design tradeoffs that have
52: security implications there.
1.335 fefe 53: fixed regex LINEEND condition
1.336 fefe 54: add .size directive to i386 syscalls
1.337 fefe 55: shove a few more bytes off the i386 socket calls
1.339 fefe 56: setjmp, longjmp and clone for x86_64 are now implemented but not tested (Olaf)

1.308 fefe 68: 0.19:
69: current gcc cvs makes __thread a keyword (Eric Troan)
1.316 fefe 70: be more strict regarding hostile DNS packets (me)
1.312 fefe 71: fix ia64 compile problems (Gerrit Pape)
1.311 fefe 72: make killpg a function and not a macro (broke bash 2.05b)
1.313 fefe 73: fix ia64 start code and unified syscall (me)
1.314 fefe 74: add sparc/strlen.S from Thomas Ogrisegg
75: add more space to ARM __jmp_buf in setjmp.h (Andre)
1.315 fefe 76: fix libcompat/syscall.S (did't compile on arm)
1.316 fefe 77: add integer overflow fix in xdr_array after bugtraq advisory (me)
1.317 fefe 78: fix x86_64 socket calls and mmap (and some more) (Gwenole Beauchesne)

1.308 fefe 81:
1.281 fefe 82: 0.18:
1.282 fefe 83: add stpcpy (from Thomas Ogrisegg)
84: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 85: add libm2.s from contrib to i386 (oops, how long has it been sitting
86: there?)
1.284 fefe 87: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.285 fefe 88: Michal Ludvig ported the diet libc to the x86_64 architecture (the
89: upcoming AMD Hammer chips!). You can't even buy the chips yet and
90: the diet libc already supports it! Amazing ;-)
91: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 92: Andre sent a patch to add ARM profiling. He says it does not work

128: adjusted lstat->lstat64 #define to make it work with function pointers
129: move __dietlibc__ #define from features.h to diet
1.267 fefe 130: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
131: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 132: Thomas also sent me profiling support (so far only on x86, but
133: profiling/PORTING describes what needs to be done for other
134: architectures)!
1.272 fefe 135: add contrib/dprof.c, also from Thomas.
1.269 fefe 136: Andreas Krennmair sent a patch to add the BSD regex interface to
137: libcompat
1.271 fefe 138: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 139: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 140: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 141: abort did not flush all stdio streams
1.277 fefe 142: fix some nasty regular expression bugs
143: write a stupid malloc checker (contrib/debug-realloc.c) to help me
144: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 145: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 146: fix DNS domain search
1.280 fefe 147: i386 memccpy exchanged esi and edi :-( I should do more checks before
148: accepting external code...
1.264 fefe 149:
1.244 fefe 150: 0.16:
151: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 152: Andre found two very embarassing bugs in my four lines of md5 glue.
153: I need to get more sleep.
1.247 fefe 154: Thanks Ogrisegg found that ptrace does not work as documented and
155: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 156: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
157: fix ptrace.h for S/390 and ARM
158: provide a PORTING document so we don't lose track of which file need
159: to be touched to port the diet libc to a new platform.
1.249 fefe 160: remove a few warnings
161: provide a prototype for usleep.
1.250 fefe 162: make __dtostr work on ARM by using long instead of long long.
163: Idea by Dirk Engling.
1.251 fefe 164: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 165: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 166: Kurt Garloff sent in patches to
167: fix struct termios on non-x86 architectures
1.254 fefe 168: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
169: create libcompat.a (and move daemon to it)
1.255 fefe 170: add getdelim and getline
171: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 172: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 173: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 174: Hans Lermen fixed i386/getenv.S
1.259 fefe 175: diet -Os no longer discards -fpic and -fno-pic

1.244 fefe 181:
1.224 fefe 182: 0.15:
1.225 fefe 183: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 184: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 185: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
186: thread-safe!
1.228 fefe 187: remove vfork and add alarm to dynamic syscalls.
188: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 189: The MD5 code generated unaligned accesses when passed an unaligned
190: pointer on little endian ARM and MIPS.
191: MIPS unified syscall didn't compile anymore.
192: Put up new mipsel target to cross compile for little endian mips.
193: The mips target will again explicitly set endianness to big endian.
194: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 195: Duh, when we removed return0, we broke tzset when the time zone parser
196: was disabled. Uwe Ohse noticed this. Thanks!
197: Fix gethostbyname to match host names case insensitively in /etc/hosts.
198: Oops, this was reported 6 weeks ago but I overlooked the email.
199: Thanks, Denis Rachal!
1.231 fefe 200: vsnprintf's zero termination was broken.
1.233 fefe 201: Uwe Ohse found a few more bugs:
202: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
203: does it correctly.
204: Make inet_aton use strtoul instead of strtol
205: fdopen would close the file descriptor if it could not malloc the
206: buffer.
207: strftime updates.
208: Make _FILE_OFFSET_BITS includes -Wundef clean
209: Andre found a typo in endian.h for big endian mips
1.234 fefe 210: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 211: strstr(whatever,"") returned NULL, not whatever. Found by a new test
212: suite entry for strstr that I wrote.
1.245 fefe 213: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 214: add <asm/sigcontext.h> for profiling support.
215: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 216: an i386 assembler getenv implementation (roughly half the size)
217: add grantpt, ptsname, unlockpt
1.236 fefe 218: add a getenv test suite entry.
1.238 fefe 219: Andre contributed an ARM assembler md5 implementation and he fixed mmap
220: on ARM.
221: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 222: getservent_r did not parse lines without aliases. Thanks, Jaroslav
223: Macodiseas!
1.240 fefe 224: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 225: removed annoying -Wconversion gcc switch
1.242 fefe 226: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 227: Kurt Garloff sent these diffs:
228: add fdatasync (and make it a pthread cancellation point)
229: numerous alpha issues, like using .quad instead of .long for
230: offsets, change strip to -strip in Makefile (so a failing strip does
231: not abort the make), try to be more friendly to the gcc 2.96 that
232: SuSE 7.1 AXP ships with.
1.224 fefe 233:
1.209 fefe 234: 0.14:
1.224 fefe 235: fix brk again (missing __brk, trivial oversight)
1.210 fefe 236: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
237: Thomas Ogrisegg!
1.211 fefe 238: Thomas also contributed a PA-RISC port including testandset, so
239: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 240: made the fake locale more believable.
241: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 242: moved _exit into the unified syscall on x86.
1.214 fefe 243: Uwe Ohse found many more bugs:
244: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
245: liblatin1 was more or less completely broken if you gave it chars as
246: arguments, not ints (signedness). execvp had a buffer overflow in
247: case a PATH element exceeded PATH_MAX, but it's not a security
248: problem since setuid programs need to set their path to some known
249: value anyway.
1.219 fefe 250: hasmntopt did not work with foo=bar style options
1.217 fefe 251: Uwe also improved ftw's stack usage.
1.214 fefe 252: Put movl instead of popl rationale in comment in i386/unified.S since
253: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 254: I discovered __attribute__((malloc)) and started using it. For gcc 3,
255: it improves the optimizer when functions return malloced pointers.
1.216 fefe 256: Steven Rostedt pointed out that my setvbuf was broken with regard to
257: size==0 and sent a patch to fix it.
1.218 fefe 258: Thomas Ogrisegg made setenv smaller.
1.220 olaf 259: Olaf: implemented the parisc clone and an atomic testandset, modified the
260: libpthread to respect the parisc UPgrowing stack. still non functional,
261: because the unified syscall uses errno :(
1.221 fefe 262: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 263: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
264: don't write anything which was no longer the case. It also
265: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 266: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 267:
1.193 fefe 268: 0.13:
1.194 fefe 269: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 270: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 271: Olaf: port to S/390!
1.196 leitner 272: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 273: res_query did not initialize last
1.199 fefe 274: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 275: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 276: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 277: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 278: rewrote __dtostr (it also has one more argument now)
1.205 fefe 279: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 280: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
281: fix strncat for the case where n == 0 (security implications?)
282: fix bsearch (it didn't find the very last element in the array, same
283: bug in both the C and the i386 assembly version).
1.205 fefe 284: fixed FNM_PATHNAME in fnmatch
1.204 fefe 285: fix brk (the syscall was documented incorrectly in the Linux man page)
286: Thanks, Thomas Ogrisegg!
1.205 fefe 287: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 288: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 289: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 290:
1.164 fefe 291: 0.12:
292: more contributions from Frank Klemm.
1.165 fefe 293: iconv can now do UCS-2, too.
1.167 fefe 294: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 295: Lots of bug fixes, and several more i386 specific versions of common
296: routines to make them smaller.
1.168 fefe 297: add memmem (a GNU extension that looks useful)
1.170 fefe 298: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 299: add pivot_root syscall, %n for *scanf.
1.169 fefe 300: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 301: add Frank Klemm's optimized md5
1.172 fefe 302: add -Os option to diet (see diet.1).
1.173 fefe 303: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 304: add 32-bit uid/gid syscalls.
1.175 fefe 305: add rand48 (thanks, Johannes Kloos)
1.176 fefe 306: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 307: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
308: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
309: fix gethostent alias list termination. Major oops.
1.178 fefe 310: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 311: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 312: DNS will now properly signal errors and set h_errno.
313: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 314: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
315: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
316: external reference to a symbol that is only in the diet libc. So,
317: when you accidentally link a diet libc compiled object file against
318: glibc, the linker will barf. This will bloat your object files, but
319: you can remove all the references with "strip -R .note" from
320: the binaries in the end (which you should do anyway).
1.182 fefe 321: fix ARM unified syscall (select did not work).
1.183 fefe 322: add getpwent_r ala glibc and replace getpwent
323: do the same for getgrent and getspent
324: remove entlib (new code is smaller)
1.184 fefe 325: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 326: add getpwnam_r and getpwuid_r
1.186 fefe 327: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 328: Olaf muddled with the dynamic linker. It's a clean-room
329: implementation in the sense that it once worked for Olaf in a clean
330: room ;)
1.188 fefe 331: add if_nameindex and if_freenameindex.
332: fixed arm unified syscalls to work with current binutils (; is no
333: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 334: changed all st_[cma]time types to signed long so comparisons against
335: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 336: fixed two bugs regarding ungetc.
337: add getusershell, setusershell, endusershell (for vs_ftpd)
338: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 339: fixed strftime (was completely hosed)
1.192 fefe 340: added real make install target
1.164 fefe 341:
1.115 fefe 342: 0.11:
343: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 344: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 345: add floor, ceil and memchr prototypes.
346: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 347: cleaner errno vs __errno_location handling
348: add placeholder iconv (iconv_open will always return EINVAL)
349: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
350: initialization of getaddrinfo.
1.119 fefe 351: fix vsnprintf %X (printed lower case)
1.120 fefe 352: I wrote a new getopt. It appears to actually work (it is POSIX
353: compliant, it does not sort argv like the GNU version) and is only
354: a little over 300 bytes on x86.
1.121 fefe 355: Guillaume Cottenceau just wrote me that strncat should be even more
356: broken than it already is: it should append n bytes AND THEN \0!
357: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 358: Fix regexec offset return. autoconf now believes that diet libc has
359: POSIX regular expressions.
1.123 fefe 360: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 361: Fix regular expression match for x* when there is no x at all.
1.125 fefe 362: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 363: Add %h to vsnprintf.
1.127 fefe 364: Add FAQ.
1.128 fefe 365: Make %h work for signed numbers and add %hh to vsnprintf.
366: initgroups ignored the group argument :-(
367: remove printf references and nested functions from glob.
1.129 fefe 368: added an errno in libpthread that will display a prominent linker
369: warning.
1.131 fefe 370: started getting rid of kernel headers. Big task! :-(
1.130 fefe 371: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 372: Olaf: added a lot of code in libdl (not yet complete), changed the
373: startup code to make it work with his libdl and ld.so (needs still work
374: too)
1.134 fefe 375: __dns_readstartfiles only took the first domain or search path.
376: Thanks, Anthony de Boer
1.133 olaf 377: Olaf: added clone and a new unified_syscall for PowerPC
378: also dynlinker is now available (i386 only at this time)
1.135 fefe 379: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 380: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 381: fixed word delimiters in regex (they looked for space, i.e. "," did
382: not work as delimiter)
1.138 fefe 383: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 384: added mkdtemp.
1.142 fefe 385: Uwe Ohse reported all of the following bugs:
386: ttyname should return 0 if !isatty.
387: realpath returns NULL if "." cannot be opened
388: putenv erroneously accepted (and mishandled) entries without "=".
389: popen returned 255 instead of 127 if /bin/sh could not be run.
390: fgetc did not set the internal EOF indicator on EOF.
391: bsearch contained an assumption about integer arithmetic overflow
392: behavior.
393: system did not set SIGCHLD and thus contained a race.
394: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 395: daemon did not check whether open returns an fd below 3
396: perror did not save errno.
1.144 olaf 397: Olaf: Peter Jones reported some problems with perror; strerror had the
398: same problem.
399: Peter also posted a patch to atexit/exit. With some modifications it is
400: now implemented.
1.145 fefe 401: Unbuffered stdio and ungetc can no longer be disabled. I will try to
402: implement part of it using ELF weak symbols.
1.146 fefe 403: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 404: Added overflow handling for strtoul and strtol.
1.149 fefe 405: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
406: it before falling back to DNS if enabled.
1.150 fefe 407: Added a littie backwards compatibility cruft for gpm (man, do these
408: sources stink!)
1.151 fefe 409: Added openpty.
1.152 fefe 410: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 411: Fix fseek return value.
1.155 fefe 412: Add dirname and basename.
1.156 fefe 413: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 414: Fixed getservent (did not allow _ and - in the aliases).
415: Thanks, Oden Eriksson
1.158 fefe 416: Added a float.h so configure believes we have ANSI header files.
417: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 418: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 419: scanf and printf function implementations
1.160 fefe 420: Imported a few more functions and optimizations from Frank Klemm (he
421: also rewrote dtostr to have more precision)
1.161 olaf 422: Olaf: checked in a new sig* function family (based on rt_sig*).
423: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 424: Made rudimentary iconv that can convert back and forth between
425: iso-8859-1, utf-8 and ucs-4 (for debugging).
426: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 427:
1.74 fefe 428: 0.10:
429: update getpagesize.
430: add personality.
1.75 fefe 431: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 432: add putchar (apparently arm-linux-gcc will substitute printf("\n")
433: with putchar('\n') behind your back...?!
1.77 fefe 434: import include/scsi/ from glibc.
1.78 fefe 435: add iopl.
1.80 fefe 436: add execl and sigdelset prototypes.
437: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 438: add RPC headers (no code yet).
1.82 fefe 439: add mlockall, munlockall
1.83 fefe 440: make "diet gcc foo.c" work.
441: added Sun RPC code and removed as many warnings as possible in a
442: heroic act of self-mutilation.
443: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 444: added getpass. mount from util-linux actually compiles now!
445: fix the sig*set routines. mount actually works now *bg*
446: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 447: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 448: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 449: add res_init.
450: add asprintf (ugh, what an ugly function).
1.89 fefe 451: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 452: add ut_name alias to ut_host in struct utmp.
453: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 454: add sysinfo, recvmsg, sendmsg.
1.93 fefe 455: add endmntent, getmntent, setmntent.
1.94 fefe 456: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 457: add setenv.
458: remove __restrict from mntent.h, add __restrict__ removal alias for
459: older gcc versions in sys/cdefs.h.
460: add rlim_t, sig_atomic_t declarations.
461: add sigsetjmp #define for __sigsetjmp (oops).
462: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 463: add a gruesome hack to printf floating point to accept %f and kludge
464: together support for %.2f. Don't look at the code, please!
1.98 fefe 465: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 466: imported fix for entlib by Jeff Garzik.
1.100 fefe 467: add glob implementation from Guillaume Cottenceau (Thanks!!)
468: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 469: add REG_ICASE and word start/end handling to my regular expressions.
470: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 471: wrap getcwd to comply to man page (the syscall returns the number of
472: bytes, not the buffer)
473: add realpath.
1.103 fefe 474: fix vfprintf.
1.104 fefe 475: fix *scanf %s zero termination.
476: add abs, labs, llabs.
1.105 fefe 477: add <sys/io.h>, ioperm syscall.
478: add flock to <sys/file.h>
1.106 fefe 479: fixes to bsearch and the regular expressions.
1.107 fefe 480: add fake herror.
1.108 fefe 481: add scandir and alphasort.
1.109 fefe 482: add killpg
1.110 fefe 483: implemented a gross hack to make libpthread compile when
484: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 485: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 486: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 487: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
488: for sending a patch.
1.114 fefe 489: add getserv*.
490: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
491: "search" from resolv.conf.
1.74 fefe 492:
1.73 fefe 493: 0.9:
1.65 fefe 494: fixed initgroups (oops)
1.66 fefe 495: Cleanup appending file open for stdio (thanks, James Antill)
496: imported vfprintf fix from James Antill.
1.67 fefe 497: add fnmatch
498: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 499: Olaf added character classes to *scanf.
1.69 fefe 500: Put object and library files into a separate directory (bin-$ARCH).
501: Add "cross" make target to make all architectures.
502: Add "diet" program and man page.
1.70 fefe 503: Add getgrnam, getgrgid
1.71 fefe 504: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 505: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 506:
1.64 fefe 507: 0.8:
1.34 fefe 508: vsnprintf(0,...) estimated the length of strings with a padding width
509: incorrectly.
1.35 fefe 510: new reboot() from Olaf.
1.36 fefe 511: added prototypes for getsockopt and setsockopt.
1.39 fefe 512: added experimental sem* and shm*
1.38 fefe 513: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 514: added setvbuf (only changes mode, not buffer)
1.41 fefe 515: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
516: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 517: added qsort() and bsearch(). Benchmark on 1000 random ints:
518: glibc: 679414 cycles qsort and 3352 cycles bsearch
519: diet libc: 300010 cycles qsort, 553 cycles bsearch
520: I have no idea why glibc is so slow.
1.43 fefe 521: added __isnan (references by libm.a from glibc).
522: added popen() and pclose(). Now the diet libc can link slsh (from
523: S-Lang!)
1.44 fefe 524: corrected usleep. It was more of an msleep until now.
1.45 fefe 525: corrected __dtostr (it looped when trying to format "0.0").
526: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 527: added ungetc (does it work?)
1.47 fefe 528: added inet_aton (yuck!)
1.50 fefe 529: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 530: added h_errno and __h_errno_location
531: added inet_ntoa
1.49 fefe 532: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 533: add bcopy, index, rindex macros
534: add isgraph and isxdigit
1.52 fefe 535: add strftime (ugh!!!)
1.53 olaf 536: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 537: Jeff Garzik contributed a spec file. I put it in contrib and hope
538: everbody knows what to do with it...
539: Olaf checked in a ton of libpthread stuff.
1.55 fefe 540: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 541: add large file backwards compatibility support (so gzip will run on
542: kernel 2.2 and 2.0)
1.57 fefe 543: added shutdown
1.58 fefe 544: added nice
545: added pseudo-locale support for is* (they are now weak aliases,
546: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
547: overwrite the default is* functions.
1.59 fefe 548: added liblatin1.a
1.60 fefe 549: added tzfile implementation (does it work for anyone else?)
1.61 fefe 550: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 551: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
552: Thanks!
1.63 fefe 553: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 554:
1.21 fefe 555: 0.7.2:
556: added several prototypes to already implemented functions and
557: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 558: added prototypes for process group and dup syscalls. Thanks to
559: Abraham again. He also contributed an implementation for daemon(),
560: an ugly BSD hack. I decided to diversify the lib/ directory a
561: little and now created a libugly/ directory for stuff like system()
562: and daemon() ;-)
563: added libstdio and moved all that stdio crap from lib/ there. The
564: idea is to start separating now what we will separate for shared
565: libraries anyway.
1.26 fefe 566: optimized x86 unified-syscall by Olaf.
1.27 fefe 567: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
568: limits.h instead)
569: added remove.c and enough cruft to limits.h to make it compile lzo,
570: lzop and bzip2.
1.28 fefe 571: added mktime, asctime_r, asctime and ctime (needed for gzip).
572: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 573: format some day (man tzfile, ugh!) :-(
1.29 fefe 574: added unlink prototype to unistd.h.
575: added gmtime and gmtime_r.
1.31 fefe 576: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 577: removed readdir glibc compatibility cruft.
1.31 fefe 578: removed stat glibc compatibility cruft.
1.32 fefe 579: oops, my fread was broken for pipes.
1.33 fefe 580: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 581:
1.9 fefe 582: 0.7.1:
1.11 fefe 583: optimized away the static arrays from __ltostr and __lltostr.
584: optimized away the static arrays (and more!) from strtoul and strtoull.
585: added system (by Olaf).
1.12 fefe 586: added tolower and toupper
1.13 fefe 587: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 588: added clone for mips (by Olaf).
589: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 590: added pause for all (by Olaf).
1.17 fefe 591: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 592: added isupper and islower.
593: added putc and putchar as macros.
1.17 fefe 594: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
595: insightful discussions and patches I partially used for the last three)
1.18 fefe 596: added getpriority and setpriority (also by Abraham)
1.19 fefe 597: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 598: oi, setjmp and longjmp were broken on other platforms, too!
599: Thanks to Sébastien Côté for reporting this.
1.9 fefe 600:
601: 0.7:
1.6 olaf 602: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 603: Initial dynamic loading glue for i386, also by Olaf.
604: We don't have a dynamic loader yet, so this is not yet usable.
605: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
606: vsprintf, writev, all by Olaf.
1.2 fefe 607: imported readdir fix from Guillaume. Mhh, can the kernel interface
608: really be this broken?
1.3 fefe 609: Found a kludgy way to detect whether the kernel includes define struct
610: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
611: not work for you, please tell me!
1.4 fefe 612: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 613: Fixed stdio line buffering. The code was already there but I forgot
614: to mark stdio and stdout as line buffered. This should really be
615: done dynamically using isatty, though.
1.8 fefe 616: Removed superfluous "if (1)" in execvp.c
1.1 cvs 617:
618: 0.6.14:
619: *scanf did not append the 0 byte for %s.
620: added creat and changed creat to call open directly instead of open64.
621: did for fread what 0.6.10 did for fwrite.
622: repaired buffered stdio a little (line buffering is still not
623: supported).
624: [All of these bugs have been reported by Guillaume. Thanks!]
625: added __pure__ to strchr and strrchr in <string.h>
626:
627: 0.6.13:
628: included COPYING to make clear that the diet libc is covered by the
629: GNU General Public License (and _not_ the LGPL). That means that
630: you need to obtain a license from me if you want to use the diet
631: libc in a proprietary program that you want to distribute.
632: The x86 unified syscall swapped arguments #4 and #5 and noone
633: noticed until now! Thanks to Guillaume Cottenceau for reporting
634: this!
635: The malloc had a subtle bug with small allocations that could cause
636: segfault. Guillaume reported it, Olaf fixed it.
637:
638: 0.6.12:
639: added assert, statfs and fstatfs
640: added include/net/if.h so fget compiles again.
641:
642: 0.6.11:
643: added putenv.
644:
645: 0.6.10:
646: fixed fwrite. It returned the number of bytes written, not the number
647: of records. Thanks to Albert D. Cahalan for pointing this out.
648: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
649: added brk and sbrk. harold@nb.com.sg made me do it.
650:
651: 0.6.9:
652: fixed execvp not to return on ENOENT
653: did for {open|read|close|seek|tell}dir what I did for stat before.
654: The glibc compatibility part is currently non-functional.
655: fixed white space handling in sscanf " (" would not match " (".
656: fixed printf to accept 'l' flag.
657: fixed getpwuid (ignored last line)
658:
659: 0.6.8:
660: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
661: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
662: added strlcpy and strlcat from OpenBSD.
663: added stat64, fstat64 and lstat64.
664: added endian.h and made ending of strlen.c endianness-aware
665: added string routines size tweak to dietfeatures.h. Most of the
666: string routines have been unrolled. This is up to three times as
667: fast but creates up to three times larger code. Now you can disable
668: the unrolling.
669: added sendfile.
670: I also added pread. It works on x86 and sparc but not on ppc and mips.
671: I have no idea what's going on. strace disagrees with the kernel.
672: Can anyone help? I asked the Linux kernel mailing list for help, too.
673: added a few aliases of the type __libc_open for open. nm on
674: libpthreads.so indicates that we will need them.
675:
676: 0.6.7:
677: the sources now compile without warnings with -Wall.
678: printf now prints "(null)" when %s is passed NULL. This can be
679: removed with WANT_NULL_PRINTF in dietfeatures.h
680: added vfprintf, execl, ttyname.
681: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
682: __dietfstat so they can use the normal kernel struct stat.
683: stat, lstat and fstat are now C wrappers that convert to the glibc
684: struct stat. So we can avoid that overhead for programs that use
685: dietlibc headers.
686:
687: 0.6.6:
688: changed the Makefiles so you can now set CFLAGS on the command line
689: added memccmp (analogous to memccpy) and strncmp.
690: Olaf fixed another bug in the sparc unified syscall.
691: Paul Clifford contributed a C version of his strlen.S that is much
692: more efficient than the previous strlen on all platforms! It also
693: looks like technology from Roswell. ;-}
694: added a "real" stdio. Well, almost. Please contribute!
695: added dietfeatures.h so you can remove features you don't need.
696: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
697: stdio now works with simple programs and minigzip from libz.
698: stdio uses some major trickery to avoid linking the stdio, stderr and
699: stdout (and reserving space for them) when they are not used.
700:
701: 0.6.5:
702: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
703: most of them bugs in the new header files, but also missing sigset
704: functions.
705: Paul Clifford contributed an assembly strlen.S for ARM and fixed
706: several bugs.
707: Fixed ppc/setjmp and mips/pipe.
708: Olaf contributed a new sparc unified syscall.
709:
710: 0.6.4:
711: declared is* static inline in getservent.
712: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
713: changed strlen to return 0 when passed NULL.
714: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
715: Scientist who actually implemented this without access to a MIPS
716: box, just from reading the architecture manual. And it worked out
717: of the box.
718: started a set of system includes, mainly so that I can use lcc and
719: my alpha-linux cross compiler (which is unable to cross-compile
720: glibc). diet libc can now be compiled without any include files
721: from a normal libc. The includes do declare more than diet libc
722: currently delivers and they are still far from complete for real
723: applications.
724: I will only add assembly versions that are smaller _and_ faster than
725: the C version. Larger routines are only accepted if they are called
726: very often and are substantially faster.
727: added i386 assembly strchr, which is smaller and faster than the old
728: version. It is, however, larger than the version contributed by
729: proton (thanks, anyway).
730: added i386 strlen (31% faster, 14% smaller)
731: "make t" will now create a map file called "mapfile".
732:
733: 0.6.3:
734: added sys_errlist, strerror and perror
735: added isblank
736: added atol
737:
738: 0.6.2:
739: mmap for ARM didn't compile. Thanks, Paul!
740:
741: 0.6.1:
742: split mmap into the architecture specific subdirectories.
743: getenv now copes with environ==NULL, thanks Paul Clifford.
744: Paul also contributed a smaller ARM startup code.
745:
746: 0.6:
747: strcat returned the wrong result. Thanks, Dietz Pröpper.
748: strtod now understands a negative exponent (oops, thanks Bertram Barth)
749: Port to arm-linux-gnu, but on the Netwinder I use for testing the
750: __dtostr does not work (I have no idea why!)
751: The MIPS port now uses (much smaller) non-PIC code. That means that
752: the applications you link against diet libc also have to be compiled
753: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
754: Thanks to Ralf Bächle for helping me with this!
755: I made subdirectories for the architectures and use VPATH to override
756: VPATH so that make finds the source file automatically. That should
757: simplify the sources greatly.
758: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
759: ARM and MIPS now also have setjmp and longjmp
760: "compile" and "load" are now make targets. Use them for djb programs.
761: added contrib/elftrunc.c which will remove unnecessary ELF headers.
762: Again, contributed from Olaf. Great work!
763:
764: 0.5.12:
765: printf also does signed numbers.
766: If you don't use atexit, dietlibc now does not link exit, only _exit.
767: *printf now correctly returns the number of bytes written.
768: Olaf contributed experimental sscanf and vsscanf implementations.
769: If passed NULL as buffer, snprintf will not write anything but still
770: return the number of bytes it would have written.
771: Initial MIPS port! (Oh, the agony!)
772: No setjmp and longjmp support yet! Please contribute!
773: I even implemented unified syscalls for MIPS. Still, MIPS code is
774: almost twice the size of SPARC code. If anyone knows why: please
775: tell me!
776:
777: 0.5.11:
778: I implemented new unified syscalls for x86, sparc and ppc, this time based
779: on .s files and not .c files, and I moved the syscalls into
780: subdirectores to clean the dietlibc sources up a little.
781: A binary consisting of printf("%s is %d\n","olaf",23) is now
782: 2864 bytes on sparc
783: 2488 bytes on intel
784: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
785: to make a few more applications work.
786: Olaf Dreesen also implemented some unified syscall stuff for x86.
787: He discovered that with our unified syscall interface it actually
788: costs <10 bytes total to make all system calls thread safe!
789: I implemented atexit() (can register up to 4 callbacks).
790: I implemented strtod and __dtostr (the opposite). Now we can add
791: floating point support to vsnprintf and sscanf!
792:
793: 0.5.10:
794: I actually saw that I can not only merge the errno handling code of
795: the system calls on x86, I can also merge the rest (including the
796: arguments) except for setting the system call number. All those
797: system calls are now just a jump to a unified system call handler.
798: I got rid of x86openclose again. The savings are substantial:
799: chown from embutils went from 7664 to 7184 bytes!
800: If I'd move the system call wrappers to assembly language, I could
801: even reduce the alignment (does not matter since it's just a jump
802: anyway) and get rid of the "ret" behind each jump (one byte per
803: system call!)
804:
805: 0.5.9:
806: added memchr, strpbrk, strstr, strtol, isspace (hehe)
807: fixed strdup
808: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
809: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
810: (no signed integers, only strings and unsigned integers (but
811: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
812: that code must be wonderful, I don't understand it at all *bg*)
813: Olaf's printf does understand padding like in "%08d" and "%8d" and
814: automatically pads pointers with '0'.
815: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
816: Thanks to proton for inspiration on this.
817: The new x86 start code also does not reference exit any more, thus saving
818: 64 bytes for executables that don't call exit explicitly.
819: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
820: Moved errno and environ to start.S, saving no byte binary size but
821: speeding up compilation and slightly shortening dietlibc.a ;-)
822: For x86: joined open and close into one assembler file, sharing the
823: errno handling. This is a feasibility test and it actually saves a
824: few bytes. I think I will reimplement the _syscall[1-6] macros on
825: all platforms now to share the errno handling code for them.
826:
827: 0.5.8:
828: fixed strchr to be able to look for 0.
829:
830: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
831: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
832: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
833: contributed by Olaf Dreesen)
834:
835: added execvp, getcwd
836:
837: fixed __xmknod
838:
839: Note: can it be that the ftw interface really is so broken that I
840: cannot implement it without having to implement some searching data
841: structure? I included an experimental ftw implementation that will
842: not follow symlinks.
843:
844: 0.5.7:
845: oops, if_nametoindex was broken!
846:
847: 0.5.6:
848: ported to ppc-linux.
849: fixed i386 sigsetjmp (I mistyped the function name)
850: included sigjmp.c
851:
852: 0.5.5:
853: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
854: actually, it wasn't fork that wasn't working for sparc, it was pipe.
855: I fixed it now.
856: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
857: fixed readdir to use getdents and not the intel inline asm
858:
859: 0.5.4:
860: ported to sparclinux (sparc32 only). Beware: does not work yet.
861: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
862:
863: 0.5.3:
864: added tcsetattr and getenv to compile e3
865:
866: 0.5.2:
867: added vhangup, tcgetattr, isatty and memcmp for fgetty
868: (http://www.fefe.de/fgetty/)
869: added localtime from uC-libc.
870:
871: 0.5.1:
872: stat and friends actually work now. Yuck! Another case of
873: translation between kernel and userland. Why can't the kernel
874: people and the libc people simply agree on a standard?
875: removed many unnecessary includes to speed up compilation.
876: added -fomit-frame-pointer and i386 compilation target to reduce code size.
877: inlined socketcall to reduce code size.
878: "load" and "compile" are examples for djb code.
879:
880: 0.5:
881: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
882: each object file is now treated with "strip -x -R .note -R .comment"
883: split each system call into a separate object file
884: added ntohs, htons, alarm, if_indextoname and if_nametoindex
885:
886: 0.4.1:
887: oops, the strchr implementation was wrong. Thanks Jens Laas!
888:
889: 0.4:
890: copied opendir and friends from uC-libc.
891: added getservent and getservby* in gerservent.c
892:
893: 0.3:
894: remove readdir system call
895: added getdents system call
896: added getpwnam/getpwuid implementation in getpwnam.c
897: added a few string functions (in str*.c)
