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
1.358 fefe 24: remove a few more warnings
1.359 fefe 25: add new 2.5 syscall #defines
26: add epoll_create, epoll_ctl and epoll_wait
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)

1.330 fefe 41: argh, atexit fell victim to bit rot (or maybe Olaf)
1.331 fefe 42: add WANT_INET_ADDR_DNS to make gethostbyname not look up IP numbers
43: but use them to fill in the struct hostent directly.
1.332 olaf 44: signal is now a correct signal (Olaf)
1.333 fefe 45: read optimizer cflags for diet -Os gcc from ~/.diet/gcc, overriding
46: the built-in defaults.
1.334 fefe 47: add file "SECURITY". I will document design tradeoffs that have
48: security implications there.
1.335 fefe 49: fixed regex LINEEND condition
1.336 fefe 50: add .size directive to i386 syscalls
1.337 fefe 51: shove a few more bytes off the i386 socket calls
1.339 fefe 52: setjmp, longjmp and clone for x86_64 are now implemented but not tested (Olaf)

1.321 fefe 58: some malloc fixes for very big numbers (Enrico Scholz, me)
1.322 fefe 59: x86_64 unified syscall did not preserve rbx violating ABI (Gwenole)

1.329 fefe 62: add asm/statfs.h to work around people using <linux/fs.h>
1.319 fefe 63:
1.308 fefe 64: 0.19:
65: current gcc cvs makes __thread a keyword (Eric Troan)
1.316 fefe 66: be more strict regarding hostile DNS packets (me)
1.312 fefe 67: fix ia64 compile problems (Gerrit Pape)
1.311 fefe 68: make killpg a function and not a macro (broke bash 2.05b)
1.313 fefe 69: fix ia64 start code and unified syscall (me)
1.314 fefe 70: add sparc/strlen.S from Thomas Ogrisegg
71: add more space to ARM __jmp_buf in setjmp.h (Andre)
1.315 fefe 72: fix libcompat/syscall.S (did't compile on arm)
1.316 fefe 73: add integer overflow fix in xdr_array after bugtraq advisory (me)
1.317 fefe 74: fix x86_64 socket calls and mmap (and some more) (Gwenole Beauchesne)

1.282 fefe 79: add stpcpy (from Thomas Ogrisegg)
80: check in mktime fix (from Luc Van Oostenryck)
1.283 fefe 81: add libm2.s from contrib to i386 (oops, how long has it been sitting
82: there?)
1.284 fefe 83: add truncate64 and ftruncate64 and prototype for truncate (only had ftruncate)
1.285 fefe 84: Michal Ludvig ported the diet libc to the x86_64 architecture (the
85: upcoming AMD Hammer chips!). You can't even buy the chips yet and
86: the diet libc already supports it! Amazing ;-)
87: Michal's patch also fixed several of the outstanding warnings. Thanks!
1.286 fefe 88: Andre sent a patch to add ARM profiling. He says it does not work
89: yet, but it's a start.

124: adjusted lstat->lstat64 #define to make it work with function pointers
125: move __dietlibc__ #define from features.h to diet
1.267 fefe 126: Thomas Ogrisegg sent x86 memccpy and strncpy routines and introduced
127: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 128: Thomas also sent me profiling support (so far only on x86, but
129: profiling/PORTING describes what needs to be done for other
130: architectures)!
1.272 fefe 131: add contrib/dprof.c, also from Thomas.
1.269 fefe 132: Andreas Krennmair sent a patch to add the BSD regex interface to
133: libcompat
1.271 fefe 134: Andre noticed that __dtostr never sets first to false. Oops!
1.274 fefe 135: Andre has provided a largely untested patch that seems to fix the problem.
1.275 fefe 136: Igor Gilitschenski sent a patch for the "%8.7lx" issue.
1.276 fefe 137: abort did not flush all stdio streams
1.277 fefe 138: fix some nasty regular expression bugs
139: write a stupid malloc checker (contrib/debug-realloc.c) to help me
140: debug my regular expressions. Please read contrib/debug-realloc.txt
1.278 fefe 141: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 142: fix DNS domain search
1.280 fefe 143: i386 memccpy exchanged esi and edi :-( I should do more checks before
144: accepting external code...
1.264 fefe 145:
1.244 fefe 146: 0.16:
147: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 148: Andre found two very embarassing bugs in my four lines of md5 glue.
149: I need to get more sleep.
1.247 fefe 150: Thanks Ogrisegg found that ptrace does not work as documented and
151: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 152: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
153: fix ptrace.h for S/390 and ARM
154: provide a PORTING document so we don't lose track of which file need
155: to be touched to port the diet libc to a new platform.
1.249 fefe 156: remove a few warnings
157: provide a prototype for usleep.
1.250 fefe 158: make __dtostr work on ARM by using long instead of long long.
159: Idea by Dirk Engling.
1.251 fefe 160: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 161: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 162: Kurt Garloff sent in patches to
163: fix struct termios on non-x86 architectures
1.254 fefe 164: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
165: create libcompat.a (and move daemon to it)
1.255 fefe 166: add getdelim and getline
167: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 168: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 169: Olaf: fixed *scanf familie. It hadn't wored with "long long".

1.244 fefe 177:
1.224 fefe 178: 0.15:
1.225 fefe 179: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 180: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 181: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
182: thread-safe!
1.228 fefe 183: remove vfork and add alarm to dynamic syscalls.
184: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 185: The MD5 code generated unaligned accesses when passed an unaligned
186: pointer on little endian ARM and MIPS.
187: MIPS unified syscall didn't compile anymore.
188: Put up new mipsel target to cross compile for little endian mips.
189: The mips target will again explicitly set endianness to big endian.
190: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 191: Duh, when we removed return0, we broke tzset when the time zone parser
192: was disabled. Uwe Ohse noticed this. Thanks!
193: Fix gethostbyname to match host names case insensitively in /etc/hosts.
194: Oops, this was reported 6 weeks ago but I overlooked the email.
195: Thanks, Denis Rachal!
1.231 fefe 196: vsnprintf's zero termination was broken.
1.233 fefe 197: Uwe Ohse found a few more bugs:
198: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
199: does it correctly.
200: Make inet_aton use strtoul instead of strtol
201: fdopen would close the file descriptor if it could not malloc the
202: buffer.
203: strftime updates.
204: Make _FILE_OFFSET_BITS includes -Wundef clean
205: Andre found a typo in endian.h for big endian mips
1.234 fefe 206: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 207: strstr(whatever,"") returned NULL, not whatever. Found by a new test
208: suite entry for strstr that I wrote.
1.245 fefe 209: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 210: add <asm/sigcontext.h> for profiling support.
211: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 212: an i386 assembler getenv implementation (roughly half the size)
213: add grantpt, ptsname, unlockpt
1.236 fefe 214: add a getenv test suite entry.
1.238 fefe 215: Andre contributed an ARM assembler md5 implementation and he fixed mmap
216: on ARM.
217: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 218: getservent_r did not parse lines without aliases. Thanks, Jaroslav
219: Macodiseas!
1.240 fefe 220: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 221: removed annoying -Wconversion gcc switch
1.242 fefe 222: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 223: Kurt Garloff sent these diffs:
224: add fdatasync (and make it a pthread cancellation point)
225: numerous alpha issues, like using .quad instead of .long for
226: offsets, change strip to -strip in Makefile (so a failing strip does
227: not abort the make), try to be more friendly to the gcc 2.96 that
228: SuSE 7.1 AXP ships with.
1.224 fefe 229:
1.209 fefe 230: 0.14:
1.224 fefe 231: fix brk again (missing __brk, trivial oversight)
1.210 fefe 232: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
233: Thomas Ogrisegg!
1.211 fefe 234: Thomas also contributed a PA-RISC port including testandset, so
235: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 236: made the fake locale more believable.
237: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 238: moved _exit into the unified syscall on x86.
1.214 fefe 239: Uwe Ohse found many more bugs:
240: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
241: liblatin1 was more or less completely broken if you gave it chars as
242: arguments, not ints (signedness). execvp had a buffer overflow in
243: case a PATH element exceeded PATH_MAX, but it's not a security
244: problem since setuid programs need to set their path to some known
245: value anyway.
1.219 fefe 246: hasmntopt did not work with foo=bar style options
1.217 fefe 247: Uwe also improved ftw's stack usage.
1.214 fefe 248: Put movl instead of popl rationale in comment in i386/unified.S since
249: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 250: I discovered __attribute__((malloc)) and started using it. For gcc 3,
251: it improves the optimizer when functions return malloced pointers.
1.216 fefe 252: Steven Rostedt pointed out that my setvbuf was broken with regard to
253: size==0 and sent a patch to fix it.
1.218 fefe 254: Thomas Ogrisegg made setenv smaller.
1.220 olaf 255: Olaf: implemented the parisc clone and an atomic testandset, modified the
256: libpthread to respect the parisc UPgrowing stack. still non functional,
257: because the unified syscall uses errno :(
1.221 fefe 258: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 259: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
260: don't write anything which was no longer the case. It also
261: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 262: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 263:
1.193 fefe 264: 0.13:
1.194 fefe 265: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 266: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 267: Olaf: port to S/390!
1.196 leitner 268: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 269: res_query did not initialize last
1.199 fefe 270: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 271: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 272: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 273: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 274: rewrote __dtostr (it also has one more argument now)
1.205 fefe 275: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 276: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
277: fix strncat for the case where n == 0 (security implications?)
278: fix bsearch (it didn't find the very last element in the array, same
279: bug in both the C and the i386 assembly version).
1.205 fefe 280: fixed FNM_PATHNAME in fnmatch
1.204 fefe 281: fix brk (the syscall was documented incorrectly in the Linux man page)
282: Thanks, Thomas Ogrisegg!
1.205 fefe 283: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 284: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 285: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 286:
1.164 fefe 287: 0.12:
288: more contributions from Frank Klemm.
1.165 fefe 289: iconv can now do UCS-2, too.
1.167 fefe 290: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 291: Lots of bug fixes, and several more i386 specific versions of common
292: routines to make them smaller.
1.168 fefe 293: add memmem (a GNU extension that looks useful)
1.170 fefe 294: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 295: add pivot_root syscall, %n for *scanf.
1.169 fefe 296: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 297: add Frank Klemm's optimized md5
1.172 fefe 298: add -Os option to diet (see diet.1).
1.173 fefe 299: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 300: add 32-bit uid/gid syscalls.
1.175 fefe 301: add rand48 (thanks, Johannes Kloos)
1.176 fefe 302: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 303: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
304: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
305: fix gethostent alias list termination. Major oops.
1.178 fefe 306: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 307: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 308: DNS will now properly signal errors and set h_errno.
309: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 310: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
311: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
312: external reference to a symbol that is only in the diet libc. So,
313: when you accidentally link a diet libc compiled object file against
314: glibc, the linker will barf. This will bloat your object files, but
315: you can remove all the references with "strip -R .note" from
316: the binaries in the end (which you should do anyway).
1.182 fefe 317: fix ARM unified syscall (select did not work).
1.183 fefe 318: add getpwent_r ala glibc and replace getpwent
319: do the same for getgrent and getspent
320: remove entlib (new code is smaller)
1.184 fefe 321: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 322: add getpwnam_r and getpwuid_r
1.186 fefe 323: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 324: Olaf muddled with the dynamic linker. It's a clean-room
325: implementation in the sense that it once worked for Olaf in a clean
326: room ;)
1.188 fefe 327: add if_nameindex and if_freenameindex.
328: fixed arm unified syscalls to work with current binutils (; is no
329: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 330: changed all st_[cma]time types to signed long so comparisons against
331: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 332: fixed two bugs regarding ungetc.
333: add getusershell, setusershell, endusershell (for vs_ftpd)
334: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 335: fixed strftime (was completely hosed)
1.192 fefe 336: added real make install target
1.164 fefe 337:
1.115 fefe 338: 0.11:
339: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 340: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 341: add floor, ceil and memchr prototypes.
342: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 343: cleaner errno vs __errno_location handling
344: add placeholder iconv (iconv_open will always return EINVAL)
345: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
346: initialization of getaddrinfo.
1.119 fefe 347: fix vsnprintf %X (printed lower case)
1.120 fefe 348: I wrote a new getopt. It appears to actually work (it is POSIX
349: compliant, it does not sort argv like the GNU version) and is only
350: a little over 300 bytes on x86.
1.121 fefe 351: Guillaume Cottenceau just wrote me that strncat should be even more
352: broken than it already is: it should append n bytes AND THEN \0!
353: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 354: Fix regexec offset return. autoconf now believes that diet libc has
355: POSIX regular expressions.
1.123 fefe 356: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 357: Fix regular expression match for x* when there is no x at all.
1.125 fefe 358: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 359: Add %h to vsnprintf.
1.127 fefe 360: Add FAQ.
1.128 fefe 361: Make %h work for signed numbers and add %hh to vsnprintf.
362: initgroups ignored the group argument :-(
363: remove printf references and nested functions from glob.
1.129 fefe 364: added an errno in libpthread that will display a prominent linker
365: warning.
1.131 fefe 366: started getting rid of kernel headers. Big task! :-(
1.130 fefe 367: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 368: Olaf: added a lot of code in libdl (not yet complete), changed the
369: startup code to make it work with his libdl and ld.so (needs still work
370: too)
1.134 fefe 371: __dns_readstartfiles only took the first domain or search path.
372: Thanks, Anthony de Boer
1.133 olaf 373: Olaf: added clone and a new unified_syscall for PowerPC
374: also dynlinker is now available (i386 only at this time)
1.135 fefe 375: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 376: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 377: fixed word delimiters in regex (they looked for space, i.e. "," did
378: not work as delimiter)
1.138 fefe 379: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 380: added mkdtemp.
1.142 fefe 381: Uwe Ohse reported all of the following bugs:
382: ttyname should return 0 if !isatty.
383: realpath returns NULL if "." cannot be opened
384: putenv erroneously accepted (and mishandled) entries without "=".
385: popen returned 255 instead of 127 if /bin/sh could not be run.
386: fgetc did not set the internal EOF indicator on EOF.
387: bsearch contained an assumption about integer arithmetic overflow
388: behavior.
389: system did not set SIGCHLD and thus contained a race.
390: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 391: daemon did not check whether open returns an fd below 3
392: perror did not save errno.
1.144 olaf 393: Olaf: Peter Jones reported some problems with perror; strerror had the
394: same problem.
395: Peter also posted a patch to atexit/exit. With some modifications it is
396: now implemented.
1.145 fefe 397: Unbuffered stdio and ungetc can no longer be disabled. I will try to
398: implement part of it using ELF weak symbols.
1.146 fefe 399: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 400: Added overflow handling for strtoul and strtol.
1.149 fefe 401: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
402: it before falling back to DNS if enabled.
1.150 fefe 403: Added a littie backwards compatibility cruft for gpm (man, do these
404: sources stink!)
1.151 fefe 405: Added openpty.
1.152 fefe 406: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 407: Fix fseek return value.
1.155 fefe 408: Add dirname and basename.
1.156 fefe 409: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 410: Fixed getservent (did not allow _ and - in the aliases).
411: Thanks, Oden Eriksson
1.158 fefe 412: Added a float.h so configure believes we have ANSI header files.
413: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 414: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 415: scanf and printf function implementations
1.160 fefe 416: Imported a few more functions and optimizations from Frank Klemm (he
417: also rewrote dtostr to have more precision)
1.161 olaf 418: Olaf: checked in a new sig* function family (based on rt_sig*).
419: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 420: Made rudimentary iconv that can convert back and forth between
421: iso-8859-1, utf-8 and ucs-4 (for debugging).
422: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 423:
1.74 fefe 424: 0.10:
425: update getpagesize.
426: add personality.
1.75 fefe 427: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 428: add putchar (apparently arm-linux-gcc will substitute printf("\n")
429: with putchar('\n') behind your back...?!
1.77 fefe 430: import include/scsi/ from glibc.
1.78 fefe 431: add iopl.
1.80 fefe 432: add execl and sigdelset prototypes.
433: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 434: add RPC headers (no code yet).
1.82 fefe 435: add mlockall, munlockall
1.83 fefe 436: make "diet gcc foo.c" work.
437: added Sun RPC code and removed as many warnings as possible in a
438: heroic act of self-mutilation.
439: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 440: added getpass. mount from util-linux actually compiles now!
441: fix the sig*set routines. mount actually works now *bg*
442: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 443: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 444: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 445: add res_init.
446: add asprintf (ugh, what an ugly function).
1.89 fefe 447: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 448: add ut_name alias to ut_host in struct utmp.
449: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 450: add sysinfo, recvmsg, sendmsg.
1.93 fefe 451: add endmntent, getmntent, setmntent.
1.94 fefe 452: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 453: add setenv.
454: remove __restrict from mntent.h, add __restrict__ removal alias for
455: older gcc versions in sys/cdefs.h.
456: add rlim_t, sig_atomic_t declarations.
457: add sigsetjmp #define for __sigsetjmp (oops).
458: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 459: add a gruesome hack to printf floating point to accept %f and kludge
460: together support for %.2f. Don't look at the code, please!
1.98 fefe 461: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 462: imported fix for entlib by Jeff Garzik.
1.100 fefe 463: add glob implementation from Guillaume Cottenceau (Thanks!!)
464: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 465: add REG_ICASE and word start/end handling to my regular expressions.
466: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 467: wrap getcwd to comply to man page (the syscall returns the number of
468: bytes, not the buffer)
469: add realpath.
1.103 fefe 470: fix vfprintf.
1.104 fefe 471: fix *scanf %s zero termination.
472: add abs, labs, llabs.
1.105 fefe 473: add <sys/io.h>, ioperm syscall.
474: add flock to <sys/file.h>
1.106 fefe 475: fixes to bsearch and the regular expressions.
1.107 fefe 476: add fake herror.
1.108 fefe 477: add scandir and alphasort.
1.109 fefe 478: add killpg
1.110 fefe 479: implemented a gross hack to make libpthread compile when
480: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 481: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 482: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 483: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
484: for sending a patch.
1.114 fefe 485: add getserv*.
486: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
487: "search" from resolv.conf.
1.74 fefe 488:
1.73 fefe 489: 0.9:
1.65 fefe 490: fixed initgroups (oops)
1.66 fefe 491: Cleanup appending file open for stdio (thanks, James Antill)
492: imported vfprintf fix from James Antill.
1.67 fefe 493: add fnmatch
494: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 495: Olaf added character classes to *scanf.
1.69 fefe 496: Put object and library files into a separate directory (bin-$ARCH).
497: Add "cross" make target to make all architectures.
498: Add "diet" program and man page.
1.70 fefe 499: Add getgrnam, getgrgid
1.71 fefe 500: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 501: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 502:
1.64 fefe 503: 0.8:
1.34 fefe 504: vsnprintf(0,...) estimated the length of strings with a padding width
505: incorrectly.
1.35 fefe 506: new reboot() from Olaf.
1.36 fefe 507: added prototypes for getsockopt and setsockopt.
1.39 fefe 508: added experimental sem* and shm*
1.38 fefe 509: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 510: added setvbuf (only changes mode, not buffer)
1.41 fefe 511: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
512: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 513: added qsort() and bsearch(). Benchmark on 1000 random ints:
514: glibc: 679414 cycles qsort and 3352 cycles bsearch
515: diet libc: 300010 cycles qsort, 553 cycles bsearch
516: I have no idea why glibc is so slow.
1.43 fefe 517: added __isnan (references by libm.a from glibc).
518: added popen() and pclose(). Now the diet libc can link slsh (from
519: S-Lang!)
1.44 fefe 520: corrected usleep. It was more of an msleep until now.
1.45 fefe 521: corrected __dtostr (it looped when trying to format "0.0").
522: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 523: added ungetc (does it work?)
1.47 fefe 524: added inet_aton (yuck!)
1.50 fefe 525: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 526: added h_errno and __h_errno_location
527: added inet_ntoa
1.49 fefe 528: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 529: add bcopy, index, rindex macros
530: add isgraph and isxdigit
1.52 fefe 531: add strftime (ugh!!!)
1.53 olaf 532: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 533: Jeff Garzik contributed a spec file. I put it in contrib and hope
534: everbody knows what to do with it...
535: Olaf checked in a ton of libpthread stuff.
1.55 fefe 536: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 537: add large file backwards compatibility support (so gzip will run on
538: kernel 2.2 and 2.0)
1.57 fefe 539: added shutdown
1.58 fefe 540: added nice
541: added pseudo-locale support for is* (they are now weak aliases,
542: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
543: overwrite the default is* functions.
1.59 fefe 544: added liblatin1.a
1.60 fefe 545: added tzfile implementation (does it work for anyone else?)
1.61 fefe 546: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 547: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
548: Thanks!
1.63 fefe 549: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 550:
1.21 fefe 551: 0.7.2:
552: added several prototypes to already implemented functions and
553: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 554: added prototypes for process group and dup syscalls. Thanks to
555: Abraham again. He also contributed an implementation for daemon(),
556: an ugly BSD hack. I decided to diversify the lib/ directory a
557: little and now created a libugly/ directory for stuff like system()
558: and daemon() ;-)
559: added libstdio and moved all that stdio crap from lib/ there. The
560: idea is to start separating now what we will separate for shared
561: libraries anyway.
1.26 fefe 562: optimized x86 unified-syscall by Olaf.
1.27 fefe 563: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
564: limits.h instead)
565: added remove.c and enough cruft to limits.h to make it compile lzo,
566: lzop and bzip2.
1.28 fefe 567: added mktime, asctime_r, asctime and ctime (needed for gzip).
568: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 569: format some day (man tzfile, ugh!) :-(
1.29 fefe 570: added unlink prototype to unistd.h.
571: added gmtime and gmtime_r.
1.31 fefe 572: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 573: removed readdir glibc compatibility cruft.
1.31 fefe 574: removed stat glibc compatibility cruft.
1.32 fefe 575: oops, my fread was broken for pipes.
1.33 fefe 576: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 577:
1.9 fefe 578: 0.7.1:
1.11 fefe 579: optimized away the static arrays from __ltostr and __lltostr.
580: optimized away the static arrays (and more!) from strtoul and strtoull.
581: added system (by Olaf).
1.12 fefe 582: added tolower and toupper
1.13 fefe 583: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 584: added clone for mips (by Olaf).
585: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 586: added pause for all (by Olaf).
1.17 fefe 587: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 588: added isupper and islower.
589: added putc and putchar as macros.
1.17 fefe 590: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
591: insightful discussions and patches I partially used for the last three)
1.18 fefe 592: added getpriority and setpriority (also by Abraham)
1.19 fefe 593: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 594: oi, setjmp and longjmp were broken on other platforms, too!
595: Thanks to Sébastien Côté for reporting this.
1.9 fefe 596:
597: 0.7:
1.6 olaf 598: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 599: Initial dynamic loading glue for i386, also by Olaf.
600: We don't have a dynamic loader yet, so this is not yet usable.
601: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
602: vsprintf, writev, all by Olaf.
1.2 fefe 603: imported readdir fix from Guillaume. Mhh, can the kernel interface
604: really be this broken?
1.3 fefe 605: Found a kludgy way to detect whether the kernel includes define struct
606: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
607: not work for you, please tell me!
1.4 fefe 608: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 609: Fixed stdio line buffering. The code was already there but I forgot
610: to mark stdio and stdout as line buffered. This should really be
611: done dynamically using isatty, though.
1.8 fefe 612: Removed superfluous "if (1)" in execvp.c
1.1 cvs 613:
614: 0.6.14:
615: *scanf did not append the 0 byte for %s.
616: added creat and changed creat to call open directly instead of open64.
617: did for fread what 0.6.10 did for fwrite.
618: repaired buffered stdio a little (line buffering is still not
619: supported).
620: [All of these bugs have been reported by Guillaume. Thanks!]
621: added __pure__ to strchr and strrchr in <string.h>
622:
623: 0.6.13:
624: included COPYING to make clear that the diet libc is covered by the
625: GNU General Public License (and _not_ the LGPL). That means that
626: you need to obtain a license from me if you want to use the diet
627: libc in a proprietary program that you want to distribute.
628: The x86 unified syscall swapped arguments #4 and #5 and noone
629: noticed until now! Thanks to Guillaume Cottenceau for reporting
630: this!
631: The malloc had a subtle bug with small allocations that could cause
632: segfault. Guillaume reported it, Olaf fixed it.
633:
634: 0.6.12:
635: added assert, statfs and fstatfs
636: added include/net/if.h so fget compiles again.
637:
638: 0.6.11:
639: added putenv.
640:
641: 0.6.10:
642: fixed fwrite. It returned the number of bytes written, not the number
643: of records. Thanks to Albert D. Cahalan for pointing this out.
644: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
645: added brk and sbrk. harold@nb.com.sg made me do it.
646:
647: 0.6.9:
648: fixed execvp not to return on ENOENT
649: did for {open|read|close|seek|tell}dir what I did for stat before.
650: The glibc compatibility part is currently non-functional.
651: fixed white space handling in sscanf " (" would not match " (".
652: fixed printf to accept 'l' flag.
653: fixed getpwuid (ignored last line)
654:
655: 0.6.8:
656: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
657: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
658: added strlcpy and strlcat from OpenBSD.
659: added stat64, fstat64 and lstat64.
660: added endian.h and made ending of strlen.c endianness-aware
661: added string routines size tweak to dietfeatures.h. Most of the
662: string routines have been unrolled. This is up to three times as
663: fast but creates up to three times larger code. Now you can disable
664: the unrolling.
665: added sendfile.
666: I also added pread. It works on x86 and sparc but not on ppc and mips.
667: I have no idea what's going on. strace disagrees with the kernel.
668: Can anyone help? I asked the Linux kernel mailing list for help, too.
669: added a few aliases of the type __libc_open for open. nm on
670: libpthreads.so indicates that we will need them.
671:
672: 0.6.7:
673: the sources now compile without warnings with -Wall.
674: printf now prints "(null)" when %s is passed NULL. This can be
675: removed with WANT_NULL_PRINTF in dietfeatures.h
676: added vfprintf, execl, ttyname.
677: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
678: __dietfstat so they can use the normal kernel struct stat.
679: stat, lstat and fstat are now C wrappers that convert to the glibc
680: struct stat. So we can avoid that overhead for programs that use
681: dietlibc headers.
682:
683: 0.6.6:
684: changed the Makefiles so you can now set CFLAGS on the command line
685: added memccmp (analogous to memccpy) and strncmp.
686: Olaf fixed another bug in the sparc unified syscall.
687: Paul Clifford contributed a C version of his strlen.S that is much
688: more efficient than the previous strlen on all platforms! It also
689: looks like technology from Roswell. ;-}
690: added a "real" stdio. Well, almost. Please contribute!
691: added dietfeatures.h so you can remove features you don't need.
692: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
693: stdio now works with simple programs and minigzip from libz.
694: stdio uses some major trickery to avoid linking the stdio, stderr and
695: stdout (and reserving space for them) when they are not used.
696:
697: 0.6.5:
698: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
699: most of them bugs in the new header files, but also missing sigset
700: functions.
701: Paul Clifford contributed an assembly strlen.S for ARM and fixed
702: several bugs.
703: Fixed ppc/setjmp and mips/pipe.
704: Olaf contributed a new sparc unified syscall.
705:
706: 0.6.4:
707: declared is* static inline in getservent.
708: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
709: changed strlen to return 0 when passed NULL.
710: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
711: Scientist who actually implemented this without access to a MIPS
712: box, just from reading the architecture manual. And it worked out
713: of the box.
714: started a set of system includes, mainly so that I can use lcc and
715: my alpha-linux cross compiler (which is unable to cross-compile
716: glibc). diet libc can now be compiled without any include files
717: from a normal libc. The includes do declare more than diet libc
718: currently delivers and they are still far from complete for real
719: applications.
720: I will only add assembly versions that are smaller _and_ faster than
721: the C version. Larger routines are only accepted if they are called
722: very often and are substantially faster.
723: added i386 assembly strchr, which is smaller and faster than the old
724: version. It is, however, larger than the version contributed by
725: proton (thanks, anyway).
726: added i386 strlen (31% faster, 14% smaller)
727: "make t" will now create a map file called "mapfile".
728:
729: 0.6.3:
730: added sys_errlist, strerror and perror
731: added isblank
732: added atol
733:
734: 0.6.2:
735: mmap for ARM didn't compile. Thanks, Paul!
736:
737: 0.6.1:
738: split mmap into the architecture specific subdirectories.
739: getenv now copes with environ==NULL, thanks Paul Clifford.
740: Paul also contributed a smaller ARM startup code.
741:
742: 0.6:
743: strcat returned the wrong result. Thanks, Dietz Pröpper.
744: strtod now understands a negative exponent (oops, thanks Bertram Barth)
745: Port to arm-linux-gnu, but on the Netwinder I use for testing the
746: __dtostr does not work (I have no idea why!)
747: The MIPS port now uses (much smaller) non-PIC code. That means that
748: the applications you link against diet libc also have to be compiled
749: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
750: Thanks to Ralf Bächle for helping me with this!
751: I made subdirectories for the architectures and use VPATH to override
752: VPATH so that make finds the source file automatically. That should
753: simplify the sources greatly.
754: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
755: ARM and MIPS now also have setjmp and longjmp
756: "compile" and "load" are now make targets. Use them for djb programs.
757: added contrib/elftrunc.c which will remove unnecessary ELF headers.
758: Again, contributed from Olaf. Great work!
759:
760: 0.5.12:
761: printf also does signed numbers.
762: If you don't use atexit, dietlibc now does not link exit, only _exit.
763: *printf now correctly returns the number of bytes written.
764: Olaf contributed experimental sscanf and vsscanf implementations.
765: If passed NULL as buffer, snprintf will not write anything but still
766: return the number of bytes it would have written.
767: Initial MIPS port! (Oh, the agony!)
768: No setjmp and longjmp support yet! Please contribute!
769: I even implemented unified syscalls for MIPS. Still, MIPS code is
770: almost twice the size of SPARC code. If anyone knows why: please
771: tell me!
772:
773: 0.5.11:
774: I implemented new unified syscalls for x86, sparc and ppc, this time based
775: on .s files and not .c files, and I moved the syscalls into
776: subdirectores to clean the dietlibc sources up a little.
777: A binary consisting of printf("%s is %d\n","olaf",23) is now
778: 2864 bytes on sparc
779: 2488 bytes on intel
780: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
781: to make a few more applications work.
782: Olaf Dreesen also implemented some unified syscall stuff for x86.
783: He discovered that with our unified syscall interface it actually
784: costs <10 bytes total to make all system calls thread safe!
785: I implemented atexit() (can register up to 4 callbacks).
786: I implemented strtod and __dtostr (the opposite). Now we can add
787: floating point support to vsnprintf and sscanf!
788:
789: 0.5.10:
790: I actually saw that I can not only merge the errno handling code of
791: the system calls on x86, I can also merge the rest (including the
792: arguments) except for setting the system call number. All those
793: system calls are now just a jump to a unified system call handler.
794: I got rid of x86openclose again. The savings are substantial:
795: chown from embutils went from 7664 to 7184 bytes!
796: If I'd move the system call wrappers to assembly language, I could
797: even reduce the alignment (does not matter since it's just a jump
798: anyway) and get rid of the "ret" behind each jump (one byte per
799: system call!)
800:
801: 0.5.9:
802: added memchr, strpbrk, strstr, strtol, isspace (hehe)
803: fixed strdup
804: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
805: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
806: (no signed integers, only strings and unsigned integers (but
807: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
808: that code must be wonderful, I don't understand it at all *bg*)
809: Olaf's printf does understand padding like in "%08d" and "%8d" and
810: automatically pads pointers with '0'.
811: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
812: Thanks to proton for inspiration on this.
813: The new x86 start code also does not reference exit any more, thus saving
814: 64 bytes for executables that don't call exit explicitly.
815: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
816: Moved errno and environ to start.S, saving no byte binary size but
817: speeding up compilation and slightly shortening dietlibc.a ;-)
818: For x86: joined open and close into one assembler file, sharing the
819: errno handling. This is a feasibility test and it actually saves a
820: few bytes. I think I will reimplement the _syscall[1-6] macros on
821: all platforms now to share the errno handling code for them.
822:
823: 0.5.8:
824: fixed strchr to be able to look for 0.
825:
826: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
827: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
828: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
829: contributed by Olaf Dreesen)
830:
831: added execvp, getcwd
832:
833: fixed __xmknod
834:
835: Note: can it be that the ftw interface really is so broken that I
836: cannot implement it without having to implement some searching data
837: structure? I included an experimental ftw implementation that will
838: not follow symlinks.
839:
840: 0.5.7:
841: oops, if_nametoindex was broken!
842:
843: 0.5.6:
844: ported to ppc-linux.
845: fixed i386 sigsetjmp (I mistyped the function name)
846: included sigjmp.c
847:
848: 0.5.5:
849: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
850: actually, it wasn't fork that wasn't working for sparc, it was pipe.
851: I fixed it now.
852: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
853: fixed readdir to use getdents and not the intel inline asm
854:
855: 0.5.4:
856: ported to sparclinux (sparc32 only). Beware: does not work yet.
857: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
858:
859: 0.5.3:
860: added tcsetattr and getenv to compile e3
861:
862: 0.5.2:
863: added vhangup, tcgetattr, isatty and memcmp for fgetty
864: (http://www.fefe.de/fgetty/)
865: added localtime from uC-libc.
866:
867: 0.5.1:
868: stat and friends actually work now. Yuck! Another case of
869: translation between kernel and userland. Why can't the kernel
870: people and the libc people simply agree on a standard?
871: removed many unnecessary includes to speed up compilation.
872: added -fomit-frame-pointer and i386 compilation target to reduce code size.
873: inlined socketcall to reduce code size.
874: "load" and "compile" are examples for djb code.
875:
876: 0.5:
877: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
878: each object file is now treated with "strip -x -R .note -R .comment"
879: split each system call into a separate object file
880: added ntohs, htons, alarm, if_indextoname and if_nametoindex
881:
882: 0.4.1:
883: oops, the strchr implementation was wrong. Thanks Jens Laas!
884:
885: 0.4:
886: copied opendir and friends from uC-libc.
887: added getservent and getservby* in gerservent.c
888:
889: 0.3:
890: remove readdir system call
891: added getdents system call
892: added getpwnam/getpwuid implementation in getpwnam.c
893: added a few string functions (in str*.c)
