77: an dietfeatures.h #define WANT_FULL_POSIX_COMPAT
1.268 fefe 78: Thomas also sent me profiling support (so far only on x86, but
79: profiling/PORTING describes what needs to be done for other
80: architectures)!
1.272 fefe 81: add contrib/dprof.c, also from Thomas.
1.269 fefe 82: Andreas Krennmair sent a patch to add the BSD regex interface to
83: libcompat
1.271 fefe 84: Andre noticed that __dtostr never sets first to false. Oops!

1.277 fefe 88: fix some nasty regular expression bugs
89: write a stupid malloc checker (contrib/debug-realloc.c) to help me

1.278 fefe 91: our i386 memchr,memcmp were broken for the count=0 case
1.279 fefe 92: fix DNS domain search
1.280 fefe 93: i386 memccpy exchanged esi and edi :-( I should do more checks before

1.244 fefe 96: 0.16:
97: "diet -v" or "diet -Os" segfaulted without further arguments.
1.246 fefe 98: Andre found two very embarassing bugs in my four lines of md5 glue.
99: I need to get more sleep.
1.247 fefe 100: Thanks Ogrisegg found that ptrace does not work as documented and
101: provided a wrapper that emulates the glibc behaviour.
1.248 fefe 102: Dirk Engling saved 8 bytes and 4 cycles in the ARM clone()
103: fix ptrace.h for S/390 and ARM
104: provide a PORTING document so we don't lose track of which file need
105: to be touched to port the diet libc to a new platform.
1.249 fefe 106: remove a few warnings
107: provide a prototype for usleep.
1.250 fefe 108: make __dtostr work on ARM by using long instead of long long.
109: Idea by Dirk Engling.
1.251 fefe 110: fix an argument counting bug in *scanf (Thomas Ogrisegg)
1.252 fefe 111: Forgot an #endif in asm/sigcontext.h (Mike Castle)
1.253 fefe 112: Kurt Garloff sent in patches to
113: fix struct termios on non-x86 architectures
1.254 fefe 114: printf("%+05d\n",500) was broken (Raimar Falke told me, Olaf fixed it)
115: create libcompat.a (and move daemon to it)
1.255 fefe 116: add getdelim and getline
117: *printf now recognize 'z' integer flag (and ignore it)
1.256 olaf 118: Dirk Engling provided a strcpy.S for ARM.
1.257 olaf 119: Olaf: fixed *scanf familie. It hadn't wored with "long long".
1.258 fefe 120: Hans Lermen fixed i386/getenv.S
1.259 fefe 121: diet -Os no longer discards -fpic and -fno-pic

1.244 fefe 127:
1.224 fefe 128: 0.15:
1.225 fefe 129: vfork sucks. I reverted to the old behavior where vfork==fork.
1.226 fefe 130: fix bsearch (and remove i386 assembly bsearch, needs to be redone).
1.227 fefe 131: Thanks Ogrisegg sent a patch to make the PA-RISC unified syscall
132: thread-safe!
1.228 fefe 133: remove vfork and add alarm to dynamic syscalls.
134: fix diet-dyn to link in dyn_dstop.o and not dyn_stop.o.
1.229 fefe 135: The MD5 code generated unaligned accesses when passed an unaligned
136: pointer on little endian ARM and MIPS.
137: MIPS unified syscall didn't compile anymore.
138: Put up new mipsel target to cross compile for little endian mips.
139: The mips target will again explicitly set endianness to big endian.
140: Compiling natively on a MIPS box should not touch the endianness.
1.230 fefe 141: Duh, when we removed return0, we broke tzset when the time zone parser
142: was disabled. Uwe Ohse noticed this. Thanks!
143: Fix gethostbyname to match host names case insensitively in /etc/hosts.
144: Oops, this was reported 6 weeks ago but I overlooked the email.
145: Thanks, Denis Rachal!
1.231 fefe 146: vsnprintf's zero termination was broken.
1.233 fefe 147: Uwe Ohse found a few more bugs:
148: Remove WANT_BUGGY_GLIBC_STRSEP. The Linux man page is broken, glibc
149: does it correctly.
150: Make inet_aton use strtoul instead of strtol
151: fdopen would close the file descriptor if it could not malloc the
152: buffer.
153: strftime updates.
154: Make _FILE_OFFSET_BITS includes -Wundef clean
155: Andre found a typo in endian.h for big endian mips
1.234 fefe 156: Ryan told me that fmod was not included in libm. Oops.
1.235 fefe 157: strstr(whatever,"") returned NULL, not whatever. Found by a new test
158: suite entry for strstr that I wrote.
1.245 fefe 159: Thomas Ogrisegg suggested or sent patches for the following:
1.236 fefe 160: add <asm/sigcontext.h> for profiling support.
161: make strncpy a #define in string.h to save a few bytes.
1.241 fefe 162: an i386 assembler getenv implementation (roughly half the size)
163: add grantpt, ptsname, unlockpt
1.236 fefe 164: add a getenv test suite entry.
1.238 fefe 165: Andre contributed an ARM assembler md5 implementation and he fixed mmap
166: on ARM.
167: add glibc macro names in sys/reboot.h. Mentioned by Laurent G. Bercot
1.239 fefe 168: getservent_r did not parse lines without aliases. Thanks, Jaroslav
169: Macodiseas!
1.240 fefe 170: fix MIPS start code (argv[0] was always corrupt)
1.241 fefe 171: removed annoying -Wconversion gcc switch
1.242 fefe 172: add -v to diet.c and fix MIPS CFLAGS in diet. Thanks, Johannes Stezenbach
1.243 fefe 173: Kurt Garloff sent these diffs:
174: add fdatasync (and make it a pthread cancellation point)
175: numerous alpha issues, like using .quad instead of .long for
176: offsets, change strip to -strip in Makefile (so a failing strip does
177: not abort the make), try to be more friendly to the gcc 2.96 that
178: SuSE 7.1 AXP ships with.
1.224 fefe 179:
1.209 fefe 180: 0.14:
1.224 fefe 181: fix brk again (missing __brk, trivial oversight)
1.210 fefe 182: a new i386/atol.S that is 4 bytes smaller (and faster, too!). Thanks,
183: Thomas Ogrisegg!
1.211 fefe 184: Thomas also contributed a PA-RISC port including testandset, so
185: libpthread will work once we implement clone! Great work, Thomas.
1.212 fefe 186: made the fake locale more believable.
187: If you need gettext, use http://www.ca.postgresql.org/~petere/gettext.html
1.213 fefe 188: moved _exit into the unified syscall on x86.
1.214 fefe 189: Uwe Ohse found many more bugs:
190: getpass EINTR handling, ttyname, sysconf_cpus with SLASH_PROC_OK,
191: liblatin1 was more or less completely broken if you gave it chars as
192: arguments, not ints (signedness). execvp had a buffer overflow in
193: case a PATH element exceeded PATH_MAX, but it's not a security
194: problem since setuid programs need to set their path to some known
195: value anyway.
1.219 fefe 196: hasmntopt did not work with foo=bar style options
1.217 fefe 197: Uwe also improved ftw's stack usage.
1.214 fefe 198: Put movl instead of popl rationale in comment in i386/unified.S since
199: three people have suggested saving a few bytes with popl now ;)
1.215 fefe 200: I discovered __attribute__((malloc)) and started using it. For gcc 3,
201: it improves the optimizer when functions return malloced pointers.
1.216 fefe 202: Steven Rostedt pointed out that my setvbuf was broken with regard to
203: size==0 and sent a patch to fix it.
1.218 fefe 204: Thomas Ogrisegg made setenv smaller.
1.220 olaf 205: Olaf: implemented the parisc clone and an atomic testandset, modified the
206: libpthread to respect the parisc UPgrowing stack. still non functional,
207: because the unified syscall uses errno :(
1.221 fefe 208: tcgetospeed read from the wrong termios field. Thanks, Gunnar Ritter!
1.222 fefe 209: Fixed asprintf (relied on vsnprintf(NULL,...) to return length but
210: don't write anything which was no longer the case. It also
211: allocated one byte unnecessarily, which Uwe Ohse found.
1.223 fefe 212: Fix ttyname (readlink does not \0-terminate, forgot to do that).
1.209 fefe 213:
1.193 fefe 214: 0.13:
1.194 fefe 215: add readdir64 and automatic mapping if _FILE_OFFSET_BITS == 64
1.199 fefe 216: make diet not include the linker safeguard stuff when preprocessing
1.207 fefe 217: Olaf: port to S/390!
1.196 leitner 218: me: fix vfork (it was put into dietlibc.a twice)
1.197 leitner 219: res_query did not initialize last
1.199 fefe 220: diet (not diet-dyn, of course) now adds -static to the gcc command line
1.198 leitner 221: fixed fflush on input streams (tic from ncurses exposed this)
1.199 fefe 222: duh, there is an alarm system call, too, so we use it and not setitimer
1.200 fefe 223: fix comparison in gmtime_r that caused Jan 1 to be converted to Dec 32.
1.201 fefe 224: rewrote __dtostr (it also has one more argument now)
1.205 fefe 225: Thanks to Erik Troan for bringing these to my attention:
1.204 fefe 226: make putenv behave like glibc (putenv("HOME") == unsetenv("HOME"))
227: fix strncat for the case where n == 0 (security implications?)
228: fix bsearch (it didn't find the very last element in the array, same
229: bug in both the C and the i386 assembly version).
1.205 fefe 230: fixed FNM_PATHNAME in fnmatch
1.204 fefe 231: fix brk (the syscall was documented incorrectly in the Linux man page)
232: Thanks, Thomas Ogrisegg!
1.205 fefe 233: added negated character classes to fnmatch (not required by POSIX)
1.206 fefe 234: make the utmp routines open utmp read-only if read-write doesn't work.
1.208 fefe 235: remove syscalls.c directory, it is obsolete now with unified syscalls
1.193 fefe 236:
1.164 fefe 237: 0.12:
238: more contributions from Frank Klemm.
1.165 fefe 239: iconv can now do UCS-2, too.
1.167 fefe 240: Imported several x86 assembly routines from Wouter van Kleunen.
1.166 fefe 241: Lots of bug fixes, and several more i386 specific versions of common
242: routines to make them smaller.
1.168 fefe 243: add memmem (a GNU extension that looks useful)
1.170 fefe 244: several changes from Michal Ludvig: inttypes.h gets C99 macros,
1.168 fefe 245: add pivot_root syscall, %n for *scanf.
1.169 fefe 246: add adjtimex (thanks, Laurent BERCOT)
1.171 fefe 247: add Frank Klemm's optimized md5
1.172 fefe 248: add -Os option to diet (see diet.1).
1.173 fefe 249: several IPv6 constants and HZ were missing, thanks Johannes Kloos.
1.174 fefe 250: add 32-bit uid/gid syscalls.
1.175 fefe 251: add rand48 (thanks, Johannes Kloos)
1.176 fefe 252: fixed a lot of bugs in getopt* (thanks, Johannes)
1.177 fefe 253: add strxfrm and tweak limits.h. glib-1.3.8 now compiles without changes.
254: add a few more module syscalls. modutils-2.4.9 now compiles without changes.
255: fix gethostent alias list termination. Major oops.
1.178 fefe 256: add execle and two DNS constants (from Johannes Kloos).
1.179 fefe 257: opendir did not close-on-exec (thanks, Laurent Bercot).
1.180 fefe 258: DNS will now properly signal errors and set h_errno.
259: A few more cleanups (thanks, Andreas Jabs and Matthias Andree).
1.181 fefe 260: Added an uber-cool linker safeguard feature! Idea by Matthias Andree.
261: If you enable WANT_SAFEGUARD in dietfeatures.h, diet will include an
262: external reference to a symbol that is only in the diet libc. So,
263: when you accidentally link a diet libc compiled object file against
264: glibc, the linker will barf. This will bloat your object files, but
265: you can remove all the references with "strip -R .note" from
266: the binaries in the end (which you should do anyway).
1.182 fefe 267: fix ARM unified syscall (select did not work).
1.183 fefe 268: add getpwent_r ala glibc and replace getpwent
269: do the same for getgrent and getspent
270: remove entlib (new code is smaller)
1.184 fefe 271: rewrite getserv* to use parselib (and provide ..._r, too)
1.185 fefe 272: add getpwnam_r and getpwuid_r
1.186 fefe 273: rewrite getproto* to use parselib (and protive ..._r, too)
1.187 fefe 274: Olaf muddled with the dynamic linker. It's a clean-room
275: implementation in the sense that it once worked for Olaf in a clean
276: room ;)
1.188 fefe 277: add if_nameindex and if_freenameindex.
278: fixed arm unified syscalls to work with current binutils (; is no
279: longer a line separator but starts a comment, switched to .macro)
1.189 fefe 280: changed all st_[cma]time types to signed long so comparisons against
281: LONG_MIN will work correctly. (GNU tar does this)
1.190 fefe 282: fixed two bugs regarding ungetc.
283: add getusershell, setusershell, endusershell (for vs_ftpd)
284: add prctl, dirfd (also for vs_ftpd)
1.191 fefe 285: fixed strftime (was completely hosed)
1.192 fefe 286: added real make install target
1.164 fefe 287:
1.115 fefe 288: 0.11:
289: fix major oops in DNS routines (only with WANT_FULL_RESOLV_CONF enabled).
1.116 fefe 290: fix vsscanf bug (Thanks, David Chappell).
1.117 fefe 291: add floor, ceil and memchr prototypes.
292: add __builtin_expect and expect #defines for gcc versions below 3.0
1.118 fefe 293: cleaner errno vs __errno_location handling
294: add placeholder iconv (iconv_open will always return EINVAL)
295: try to remove kernel 2.4 header dependency in IPv6 sockaddr_in6
296: initialization of getaddrinfo.
1.119 fefe 297: fix vsnprintf %X (printed lower case)
1.120 fefe 298: I wrote a new getopt. It appears to actually work (it is POSIX
299: compliant, it does not sort argv like the GNU version) and is only
300: a little over 300 bytes on x86.
1.121 fefe 301: Guillaume Cottenceau just wrote me that strncat should be even more
302: broken than it already is: it should append n bytes AND THEN \0!
303: I wonder how many programmers have produces off-by-one errors here...
1.122 fefe 304: Fix regexec offset return. autoconf now believes that diet libc has
305: POSIX regular expressions.
1.123 fefe 306: Fix fnmatch (a/b/* matched a/b/c/d even if FNM_PATHNAME was set)
1.124 fefe 307: Fix regular expression match for x* when there is no x at all.
1.125 fefe 308: Fix memory leak in error case in gethostbyname(2|). Thanks, Dietz Pröpper.
1.126 fefe 309: Add %h to vsnprintf.
1.127 fefe 310: Add FAQ.
1.128 fefe 311: Make %h work for signed numbers and add %hh to vsnprintf.
312: initgroups ignored the group argument :-(
313: remove printf references and nested functions from glob.
1.129 fefe 314: added an errno in libpthread that will display a prominent linker
315: warning.
1.131 fefe 316: started getting rid of kernel headers. Big task! :-(
1.130 fefe 317: add res_mkquery. The diet libc can now compile and link mtr.
1.132 olaf 318: Olaf: added a lot of code in libdl (not yet complete), changed the
319: startup code to make it work with his libdl and ld.so (needs still work
320: too)
1.134 fefe 321: __dns_readstartfiles only took the first domain or search path.
322: Thanks, Anthony de Boer
1.133 olaf 323: Olaf: added clone and a new unified_syscall for PowerPC
324: also dynlinker is now available (i386 only at this time)
1.135 fefe 325: crufted together a stdarg.h implementation from the various gcc headers.
1.136 fefe 326: implement getopt_long (ugh, the GNU people need professional help)
1.137 fefe 327: fixed word delimiters in regex (they looked for space, i.e. "," did
328: not work as delimiter)
1.138 fefe 329: errno.h now declares sys_errlist and sys_nerr.
1.143 fefe 330: added mkdtemp.
1.142 fefe 331: Uwe Ohse reported all of the following bugs:
332: ttyname should return 0 if !isatty.
333: realpath returns NULL if "." cannot be opened
334: putenv erroneously accepted (and mishandled) entries without "=".
335: popen returned 255 instead of 127 if /bin/sh could not be run.
336: fgetc did not set the internal EOF indicator on EOF.
337: bsearch contained an assumption about integer arithmetic overflow
338: behavior.
339: system did not set SIGCHLD and thus contained a race.
340: popen did not set close-on-exec and could leak an fd on malloc error.
1.147 fefe 341: daemon did not check whether open returns an fd below 3
342: perror did not save errno.
1.144 olaf 343: Olaf: Peter Jones reported some problems with perror; strerror had the
344: same problem.
345: Peter also posted a patch to atexit/exit. With some modifications it is
346: now implemented.
1.145 fefe 347: Unbuffered stdio and ungetc can no longer be disabled. I will try to
348: implement part of it using ELF weak symbols.
1.146 fefe 349: Added minimal sysconf (tehe) from David Chappell.
1.148 fefe 350: Added overflow handling for strtoul and strtol.
1.149 fefe 351: Added WANT_ETC_HOSTS in dietfeatures.h and made gethostbyname/2 use
352: it before falling back to DNS if enabled.
1.150 fefe 353: Added a littie backwards compatibility cruft for gpm (man, do these
354: sources stink!)
1.151 fefe 355: Added openpty.
1.152 fefe 356: Squeeze a few bytes off the is* routines, courtesy of Peter Jones.
1.154 fefe 357: Fix fseek return value.
1.155 fefe 358: Add dirname and basename.
1.156 fefe 359: Add a few i386 math routines contributed by Frank Klemm.
1.157 fefe 360: Fixed getservent (did not allow _ and - in the aliases).
361: Thanks, Oden Eriksson
1.158 fefe 362: Added a float.h so configure believes we have ANSI header files.
363: Fix a lot more stdio bugs that Uwe Ohse pointed out.
1.162 fefe 364: Olaf: has added a new scanf and printf core that is suitable for all
1.159 olaf 365: scanf and printf function implementations
1.160 fefe 366: Imported a few more functions and optimizations from Frank Klemm (he
367: also rewrote dtostr to have more precision)
1.161 olaf 368: Olaf: checked in a new sig* function family (based on rt_sig*).
369: legacy <2.2 signal-handling doesn't work at the moment.
1.163 fefe 370: Made rudimentary iconv that can convert back and forth between
371: iso-8859-1, utf-8 and ucs-4 (for debugging).
372: Thanks to Markus Kuhn for the excellent utf-8(7)!
1.115 fefe 373:
1.74 fefe 374: 0.10:
375: update getpagesize.
376: add personality.
1.75 fefe 377: add "%*s" and "%*.*s" support to vsnprintf.
1.76 fefe 378: add putchar (apparently arm-linux-gcc will substitute printf("\n")
379: with putchar('\n') behind your back...?!
1.77 fefe 380: import include/scsi/ from glibc.
1.78 fefe 381: add iopl.
1.80 fefe 382: add execl and sigdelset prototypes.
383: add getopt_long stuff to getopt.h (may compile but won't link).
1.81 fefe 384: add RPC headers (no code yet).
1.82 fefe 385: add mlockall, munlockall
1.83 fefe 386: make "diet gcc foo.c" work.
387: added Sun RPC code and removed as many warnings as possible in a
388: heroic act of self-mutilation.
389: added getproto* and getdtablesize for the RPC cruft :-(
1.84 fefe 390: added getpass. mount from util-linux actually compiles now!
391: fix the sig*set routines. mount actually works now *bg*
392: fix fwrite dividing by zero when trying to fwrite n records of size 0.
1.85 fefe 393: added an initial regex implementation (3500 bytes!!!).
1.87 fefe 394: add llseek and lseek64 with optional lseek fall-back.
1.88 fefe 395: add res_init.
396: add asprintf (ugh, what an ugly function).
1.89 fefe 397: expanded arpa/nameser.h to include backwards compatibility defines
1.90 fefe 398: add ut_name alias to ut_host in struct utmp.
399: add inet_ntop, inet_pton, gethostbyname2.
1.92 fefe 400: add sysinfo, recvmsg, sendmsg.
1.93 fefe 401: add endmntent, getmntent, setmntent.
1.94 fefe 402: fix fnmatch (thanks, Guillaume Cottenceau!)
1.96 fefe 403: add setenv.
404: remove __restrict from mntent.h, add __restrict__ removal alias for
405: older gcc versions in sys/cdefs.h.
406: add rlim_t, sig_atomic_t declarations.
407: add sigsetjmp #define for __sigsetjmp (oops).
408: (Thanks to Chris Siebenmann for these three bug reports)
1.97 fefe 409: add a gruesome hack to printf floating point to accept %f and kludge
410: together support for %.2f. Don't look at the code, please!
1.98 fefe 411: fixed tcsetpgrp (oops, this is embarassing! Thanks, Chris Siebenmann)
1.99 fefe 412: imported fix for entlib by Jeff Garzik.
1.100 fefe 413: add glob implementation from Guillaume Cottenceau (Thanks!!)
414: add libdl fragments from Olaf (Yeah! One step closer to dynamic linking!)
1.101 fefe 415: add REG_ICASE and word start/end handling to my regular expressions.
416: my regular expressions now actually match substrings (i.e. "foobar" to "bar").
1.102 fefe 417: wrap getcwd to comply to man page (the syscall returns the number of
418: bytes, not the buffer)
419: add realpath.
1.103 fefe 420: fix vfprintf.
1.104 fefe 421: fix *scanf %s zero termination.
422: add abs, labs, llabs.
1.105 fefe 423: add <sys/io.h>, ioperm syscall.
424: add flock to <sys/file.h>
1.106 fefe 425: fixes to bsearch and the regular expressions.
1.107 fefe 426: add fake herror.
1.108 fefe 427: add scandir and alphasort.
1.109 fefe 428: add killpg
1.110 fefe 429: implemented a gross hack to make libpthread compile when
430: dietfeatures.h does not define WANT_THREAD_SAFE (it's empty then).
1.111 fefe 431: add getaddrinfo and freeaddrinfo (man, what a fucked up interface!)
1.112 fefe 432: fix sigsuspend (syscall had completely fscked up arguments!)
1.113 fefe 433: RLIM_INFINITY from the kernel is broken. Thanks to Chris Siebenmann
434: for sending a patch.
1.114 fefe 435: add getserv*.
436: add WANT_FULL_RESOLV_CONF so that the DNS routines use "domain" and
437: "search" from resolv.conf.
1.74 fefe 438:
1.73 fefe 439: 0.9:
1.65 fefe 440: fixed initgroups (oops)
1.66 fefe 441: Cleanup appending file open for stdio (thanks, James Antill)
442: imported vfprintf fix from James Antill.
1.67 fefe 443: add fnmatch
444: change index, rindex and bcmp as weak ELF symbols (were #defined before)
1.68 fefe 445: Olaf added character classes to *scanf.
1.69 fefe 446: Put object and library files into a separate directory (bin-$ARCH).
447: Add "cross" make target to make all architectures.
448: Add "diet" program and man page.
1.70 fefe 449: Add getgrnam, getgrgid
1.71 fefe 450: Add cfmakeraw (Thanks, Antonio Musumeci)
1.72 fefe 451: localtime won't call gettimeofday when the tzfile parser is used.
1.65 fefe 452:
1.64 fefe 453: 0.8:
1.34 fefe 454: vsnprintf(0,...) estimated the length of strings with a padding width
455: incorrectly.
1.35 fefe 456: new reboot() from Olaf.
1.36 fefe 457: added prototypes for getsockopt and setsockopt.
1.39 fefe 458: added experimental sem* and shm*
1.38 fefe 459: define EXIT_SUCCESS and EXIT_FAILURE
1.40 fefe 460: added setvbuf (only changes mode, not buffer)
1.41 fefe 461: added dietwarning.h (woohoo, linker warnings!) and used it to warn of
462: insecurity (system, sprintf) or bloat (printf and stdio).
1.42 fefe 463: added qsort() and bsearch(). Benchmark on 1000 random ints:
464: glibc: 679414 cycles qsort and 3352 cycles bsearch
465: diet libc: 300010 cycles qsort, 553 cycles bsearch
466: I have no idea why glibc is so slow.
1.43 fefe 467: added __isnan (references by libm.a from glibc).
468: added popen() and pclose(). Now the diet libc can link slsh (from
469: S-Lang!)
1.44 fefe 470: corrected usleep. It was more of an msleep until now.
1.45 fefe 471: corrected __dtostr (it looped when trying to format "0.0").
472: several fixes to stdio (thanks to S-Lang's excellent test suite!)
1.46 fefe 473: added ungetc (does it work?)
1.47 fefe 474: added inet_aton (yuck!)
1.50 fefe 475: added gethostbyname, gethostbyaddr, gethostbyname_r and gethostbyaddr_r
1.48 fefe 476: added h_errno and __h_errno_location
477: added inet_ntoa
1.49 fefe 478: added setpgrp and getpgrp, strsignal and execv (thanks, Olaf)
1.51 fefe 479: add bcopy, index, rindex macros
480: add isgraph and isxdigit
1.52 fefe 481: add strftime (ugh!!!)
1.53 olaf 482: Olaf fixed strftime, gmtime_r leap year bug.
1.54 fefe 483: Jeff Garzik contributed a spec file. I put it in contrib and hope
484: everbody knows what to do with it...
485: Olaf checked in a ton of libpthread stuff.
1.55 fefe 486: added mkstemp using /dev/urandom (harder to guess than getpid()).
1.56 fefe 487: add large file backwards compatibility support (so gzip will run on
488: kernel 2.2 and 2.0)
1.57 fefe 489: added shutdown
1.58 fefe 490: added nice
491: added pseudo-locale support for is* (they are now weak aliases,
492: isupper -> __isupper_ascii etc). So, for example, liblatin1 can
493: overwrite the default is* functions.
1.59 fefe 494: added liblatin1.a
1.60 fefe 495: added tzfile implementation (does it work for anyone else?)
1.61 fefe 496: added syslog(3) (thanks to Rene Müller!)
1.62 fefe 497: Jeff Garzik contributed getgr*, getpw* and getsp* in one tiny package.
498: Thanks!
1.63 fefe 499: merged duplicate code in execv and execvp into exec_lib.o
1.34 fefe 500:
1.21 fefe 501: 0.7.2:
502: added several prototypes to already implemented functions and
503: <sys/reboot.h>. Thanks for Abraham for pointing this out.
1.22 fefe 504: added prototypes for process group and dup syscalls. Thanks to
505: Abraham again. He also contributed an implementation for daemon(),
506: an ugly BSD hack. I decided to diversify the lib/ directory a
507: little and now created a libugly/ directory for stuff like system()
508: and daemon() ;-)
509: added libstdio and moved all that stdio crap from lib/ there. The
510: idea is to start separating now what we will separate for shared
511: libraries anyway.
1.26 fefe 512: optimized x86 unified-syscall by Olaf.
1.27 fefe 513: added limits.h, removed __ARCHBITS from endian.h (use __WORDSIZE from
514: limits.h instead)
515: added remove.c and enough cruft to limits.h to make it compile lzo,
516: lzop and bzip2.
1.28 fefe 517: added mktime, asctime_r, asctime and ctime (needed for gzip).
518: Someone will need to implement a reader for the glibc localtime file
1.31 fefe 519: format some day (man tzfile, ugh!) :-(
1.29 fefe 520: added unlink prototype to unistd.h.
521: added gmtime and gmtime_r.
1.31 fefe 522: fixed sparc unified syscall error handling (please upgrade!).
1.30 fefe 523: removed readdir glibc compatibility cruft.
1.31 fefe 524: removed stat glibc compatibility cruft.
1.32 fefe 525: oops, my fread was broken for pipes.
1.33 fefe 526: Olaf found a bug in pipe() for sparc, too.
1.21 fefe 527:
1.9 fefe 528: 0.7.1:
1.11 fefe 529: optimized away the static arrays from __ltostr and __lltostr.
530: optimized away the static arrays (and more!) from strtoul and strtoull.
531: added system (by Olaf).
1.12 fefe 532: added tolower and toupper
1.13 fefe 533: added getopt from Olaf (~600 bytes on x86!)
1.14 fefe 534: added clone for mips (by Olaf).
535: fixed longjmp and setjmp on sparc not to require glibc include files.
1.15 olaf 536: added pause for all (by Olaf).
1.17 fefe 537: added __attribute__ ((__const__)) to ctype.h
1.16 fefe 538: added isupper and islower.
539: added putc and putchar as macros.
1.17 fefe 540: added strcasecmp and strncasecmp (thanks to Abraham vd Merwe for
541: insightful discussions and patches I partially used for the last three)
1.18 fefe 542: added getpriority and setpriority (also by Abraham)
1.19 fefe 543: oops, I broke strtoul in a recent optimization attempt.
1.20 fefe 544: oi, setjmp and longjmp were broken on other platforms, too!
545: Thanks to Sébastien Côté for reporting this.
1.9 fefe 546:
547: 0.7:
1.6 olaf 548: clone support for i386,alpha,arm and sparc by Olaf.
1.1 cvs 549: Initial dynamic loading glue for i386, also by Olaf.
550: We don't have a dynamic loader yet, so this is not yet usable.
551: added readv, sigdelset, sigaltstack, sigfillset, sigismember, usleep,
552: vsprintf, writev, all by Olaf.
1.2 fefe 553: imported readdir fix from Guillaume. Mhh, can the kernel interface
554: really be this broken?
1.3 fefe 555: Found a kludgy way to detect whether the kernel includes define struct
556: stat64 (they also define STAT64_HAS_BROKEN_ST_INO). If this does
557: not work for you, please tell me!
1.4 fefe 558: Removed bogus __seek_types enum, it's a bunch of #defines now.
1.7 fefe 559: Fixed stdio line buffering. The code was already there but I forgot
560: to mark stdio and stdout as line buffered. This should really be
561: done dynamically using isatty, though.
1.8 fefe 562: Removed superfluous "if (1)" in execvp.c
1.1 cvs 563:
564: 0.6.14:
565: *scanf did not append the 0 byte for %s.
566: added creat and changed creat to call open directly instead of open64.
567: did for fread what 0.6.10 did for fwrite.
568: repaired buffered stdio a little (line buffering is still not
569: supported).
570: [All of these bugs have been reported by Guillaume. Thanks!]
571: added __pure__ to strchr and strrchr in <string.h>
572:
573: 0.6.13:
574: included COPYING to make clear that the diet libc is covered by the
575: GNU General Public License (and _not_ the LGPL). That means that
576: you need to obtain a license from me if you want to use the diet
577: libc in a proprietary program that you want to distribute.
578: The x86 unified syscall swapped arguments #4 and #5 and noone
579: noticed until now! Thanks to Guillaume Cottenceau for reporting
580: this!
581: The malloc had a subtle bug with small allocations that could cause
582: segfault. Guillaume reported it, Olaf fixed it.
583:
584: 0.6.12:
585: added assert, statfs and fstatfs
586: added include/net/if.h so fget compiles again.
587:
588: 0.6.11:
589: added putenv.
590:
591: 0.6.10:
592: fixed fwrite. It returned the number of bytes written, not the number
593: of records. Thanks to Albert D. Cahalan for pointing this out.
594: fixed fgets. It returned EOF on empty lines. Thanks, Erik Frey.
595: added brk and sbrk. harold@nb.com.sg made me do it.
596:
597: 0.6.9:
598: fixed execvp not to return on ENOENT
599: did for {open|read|close|seek|tell}dir what I did for stat before.
600: The glibc compatibility part is currently non-functional.
601: fixed white space handling in sscanf " (" would not match " (".
602: fixed printf to accept 'l' flag.
603: fixed getpwuid (ignored last line)
604:
605: 0.6.8:
606: Olaf contributed initial thread-safe syscalls for i386, alpha, sparc,
607: mips and arm. I did the one for ppc. They can be enabled in dietfeatures.h.
608: added strlcpy and strlcat from OpenBSD.
609: added stat64, fstat64 and lstat64.
610: added endian.h and made ending of strlen.c endianness-aware
611: added string routines size tweak to dietfeatures.h. Most of the
612: string routines have been unrolled. This is up to three times as
613: fast but creates up to three times larger code. Now you can disable
614: the unrolling.
615: added sendfile.
616: I also added pread. It works on x86 and sparc but not on ppc and mips.
617: I have no idea what's going on. strace disagrees with the kernel.
618: Can anyone help? I asked the Linux kernel mailing list for help, too.
619: added a few aliases of the type __libc_open for open. nm on
620: libpthreads.so indicates that we will need them.
621:
622: 0.6.7:
623: the sources now compile without warnings with -Wall.
624: printf now prints "(null)" when %s is passed NULL. This can be
625: removed with WANT_NULL_PRINTF in dietfeatures.h
626: added vfprintf, execl, ttyname.
627: stat, lstat and fstat are now #defined to __dietstat, __dietlstat and
628: __dietfstat so they can use the normal kernel struct stat.
629: stat, lstat and fstat are now C wrappers that convert to the glibc
630: struct stat. So we can avoid that overhead for programs that use
631: dietlibc headers.
632:
633: 0.6.6:
634: changed the Makefiles so you can now set CFLAGS on the command line
635: added memccmp (analogous to memccpy) and strncmp.
636: Olaf fixed another bug in the sparc unified syscall.
637: Paul Clifford contributed a C version of his strlen.S that is much
638: more efficient than the previous strlen on all platforms! It also
639: looks like technology from Roswell. ;-}
640: added a "real" stdio. Well, almost. Please contribute!
641: added dietfeatures.h so you can remove features you don't need.
642: removed debug code from vsnprintf that changed \0 to ' ' (argh!).
643: stdio now works with simple programs and minigzip from libz.
644: stdio uses some major trickery to avoid linking the stdio, stderr and
645: stdout (and reserving space for them) when they are not used.
646:
647: 0.6.5:
648: Red Plait <redplait@ixcelerator.com> found several bugs in diet libc,
649: most of them bugs in the new header files, but also missing sigset
650: functions.
651: Paul Clifford contributed an assembly strlen.S for ARM and fixed
652: several bugs.
653: Fixed ppc/setjmp and mips/pipe.
654: Olaf contributed a new sparc unified syscall.
655:
656: 0.6.4:
657: declared is* static inline in getservent.
658: added assert_fail, strtoul, isalpha, isdigit, isalnum, isascii.
659: changed strlen to return 0 when passed NULL.
660: new, much smaller unified syscall for MIPS. Thanks to Olaf the Mad
661: Scientist who actually implemented this without access to a MIPS
662: box, just from reading the architecture manual. And it worked out
663: of the box.
664: started a set of system includes, mainly so that I can use lcc and
665: my alpha-linux cross compiler (which is unable to cross-compile
666: glibc). diet libc can now be compiled without any include files
667: from a normal libc. The includes do declare more than diet libc
668: currently delivers and they are still far from complete for real
669: applications.
670: I will only add assembly versions that are smaller _and_ faster than
671: the C version. Larger routines are only accepted if they are called
672: very often and are substantially faster.
673: added i386 assembly strchr, which is smaller and faster than the old
674: version. It is, however, larger than the version contributed by
675: proton (thanks, anyway).
676: added i386 strlen (31% faster, 14% smaller)
677: "make t" will now create a map file called "mapfile".
678:
679: 0.6.3:
680: added sys_errlist, strerror and perror
681: added isblank
682: added atol
683:
684: 0.6.2:
685: mmap for ARM didn't compile. Thanks, Paul!
686:
687: 0.6.1:
688: split mmap into the architecture specific subdirectories.
689: getenv now copes with environ==NULL, thanks Paul Clifford.
690: Paul also contributed a smaller ARM startup code.
691:
692: 0.6:
693: strcat returned the wrong result. Thanks, Dietz Pröpper.
694: strtod now understands a negative exponent (oops, thanks Bertram Barth)
695: Port to arm-linux-gnu, but on the Netwinder I use for testing the
696: __dtostr does not work (I have no idea why!)
697: The MIPS port now uses (much smaller) non-PIC code. That means that
698: the applications you link against diet libc also have to be compiled
699: non-PIC. I suggest copying the CFLAGS from the diet libc Makefile.
700: Thanks to Ralf Bächle for helping me with this!
701: I made subdirectories for the architectures and use VPATH to override
702: VPATH so that make finds the source file automatically. That should
703: simplify the sources greatly.
704: Olaf Dreesen contributed Alpha support including setjmp and longjmp!
705: ARM and MIPS now also have setjmp and longjmp
706: "compile" and "load" are now make targets. Use them for djb programs.
707: added contrib/elftrunc.c which will remove unnecessary ELF headers.
708: Again, contributed from Olaf. Great work!
709:
710: 0.5.12:
711: printf also does signed numbers.
712: If you don't use atexit, dietlibc now does not link exit, only _exit.
713: *printf now correctly returns the number of bytes written.
714: Olaf contributed experimental sscanf and vsscanf implementations.
715: If passed NULL as buffer, snprintf will not write anything but still
716: return the number of bytes it would have written.
717: Initial MIPS port! (Oh, the agony!)
718: No setjmp and longjmp support yet! Please contribute!
719: I even implemented unified syscalls for MIPS. Still, MIPS code is
720: almost twice the size of SPARC code. If anyone knows why: please
721: tell me!
722:
723: 0.5.11:
724: I implemented new unified syscalls for x86, sparc and ppc, this time based
725: on .s files and not .c files, and I moved the syscalls into
726: subdirectores to clean the dietlibc sources up a little.
727: A binary consisting of printf("%s is %d\n","olaf",23) is now
728: 2864 bytes on sparc
729: 2488 bytes on intel
730: I kludgily implemented fprintf(stdout,... and fprintf(stderr,...
731: to make a few more applications work.
732: Olaf Dreesen also implemented some unified syscall stuff for x86.
733: He discovered that with our unified syscall interface it actually
734: costs <10 bytes total to make all system calls thread safe!
735: I implemented atexit() (can register up to 4 callbacks).
736: I implemented strtod and __dtostr (the opposite). Now we can add
737: floating point support to vsnprintf and sscanf!

739: 0.5.10:
740: I actually saw that I can not only merge the errno handling code of
741: the system calls on x86, I can also merge the rest (including the
742: arguments) except for setting the system call number. All those
743: system calls are now just a jump to a unified system call handler.
744: I got rid of x86openclose again. The savings are substantial:
745: chown from embutils went from 7664 to 7184 bytes!
746: If I'd move the system call wrappers to assembly language, I could
747: even reduce the alignment (does not matter since it's just a jump
748: anyway) and get rid of the "ret" behind each jump (one byte per
749: system call!)
750:
751: 0.5.9:
752: added memchr, strpbrk, strstr, strtol, isspace (hehe)
753: fixed strdup
754: fixed return values for strcpy and strcat (thanks to Norbert Berzen)
755: Olaf Dreesen contributed a strtol and initial {sn|vsn|}printf implementation
756: (no signed integers, only strings and unsigned integers (but
757: supporting octal, hex and decimal). Thanks, Olaf! (by the way:
758: that code must be wonderful, I don't understand it at all *bg*)
759: Olaf's printf does understand padding like in "%08d" and "%8d" and
760: automatically pads pointers with '0'.
761: Rewrote the x86 start code, old: 22 instructions, new: 12 instructions.
762: Thanks to proton for inspiration on this.
763: The new x86 start code also does not reference exit any more, thus saving
764: 64 bytes for executables that don't call exit explicitly.
765: [insert maniacal laughter] EVERY BYTE COUNTS!1!! ;-)
766: Moved errno and environ to start.S, saving no byte binary size but
767: speeding up compilation and slightly shortening dietlibc.a ;-)
768: For x86: joined open and close into one assembler file, sharing the
769: errno handling. This is a feasibility test and it actually saves a
770: few bytes. I think I will reimplement the _syscall[1-6] macros on
771: all platforms now to share the errno handling code for them.
772:
773: 0.5.8:
774: fixed strchr to be able to look for 0.
775:
776: added _llseek, ftruncate, getpgid, getresgid, getresuid, getsid,
777: memccpy, memmove, mprotect, setregid, setresgid, setresuid, setreuid,
778: strncpy, swapon, truncate, strtok, strtok_r, strspn, strcspn (all
779: contributed by Olaf Dreesen)
780:
781: added execvp, getcwd
782:
783: fixed __xmknod
784:
785: Note: can it be that the ftw interface really is so broken that I
786: cannot implement it without having to implement some searching data
787: structure? I included an experimental ftw implementation that will
788: not follow symlinks.
789:
790: 0.5.7:
791: oops, if_nametoindex was broken!
792:
793: 0.5.6:
794: ported to ppc-linux.
795: fixed i386 sigsetjmp (I mistyped the function name)
796: included sigjmp.c
797:
798: 0.5.5:
799: added wait, sys_siglist, longjmp/setjmp/sigsetjmp for i386 and sparc
800: actually, it wasn't fork that wasn't working for sparc, it was pipe.
801: I fixed it now.
802: dietlibc/SPARC assumes -msupersparc (does not provide div, mul, etc)
803: fixed readdir to use getdents and not the intel inline asm
804:
805: 0.5.4:
806: ported to sparclinux (sparc32 only). Beware: does not work yet.
807: added raise, abort, readlink, strcat, geteuid, geteuid, wait3, access
808:
809: 0.5.3:
810: added tcsetattr and getenv to compile e3
811:
812: 0.5.2:
813: added vhangup, tcgetattr, isatty and memcmp for fgetty
814: (http://www.fefe.de/fgetty/)
815: added localtime from uC-libc.
816:
817: 0.5.1:
818: stat and friends actually work now. Yuck! Another case of
819: translation between kernel and userland. Why can't the kernel
820: people and the libc people simply agree on a standard?
821: removed many unnecessary includes to speed up compilation.
822: added -fomit-frame-pointer and i386 compilation target to reduce code size.
823: inlined socketcall to reduce code size.
824: "load" and "compile" are examples for djb code.
825:
826: 0.5:
827: Olaf Dreesen contributed a much smaller implementation of malloc and friends.
828: each object file is now treated with "strip -x -R .note -R .comment"
829: split each system call into a separate object file
830: added ntohs, htons, alarm, if_indextoname and if_nametoindex
831:
832: 0.4.1:
833: oops, the strchr implementation was wrong. Thanks Jens Laas!
834:
835: 0.4:
836: copied opendir and friends from uC-libc.
837: added getservent and getservby* in gerservent.c
838:
839: 0.3:
840: remove readdir system call
841: added getdents system call
842: added getpwnam/getpwuid implementation in getpwnam.c
843: added a few string functions (in str*.c)
