|
F=New Feature
|
|
|
|
Start (V0.1)
|
|
|
|
B A symbol and it's indirected counterpart cannot be used both - fixed.
|
|
|
|
B __stdio.c used the wrong flag for testing if filehandle has to be closed
|
|
so the standard filehandle was closed three times - fixed.
|
|
|
|
P memchr.c changed - the C code looks not very good, but the assembler
|
|
code is very smart now.
|
|
|
|
F Half initialized local arrays reference bzero() - added.
|
|
|
|
M malloc now rounds even _MSTEP up to full MMU page.
|
|
|
|
P strcat(),strncat(),strcpy(),strncpy(),strchr(),strrchr() rewritten in asm.
|
|
|
|
B strcmp(),strncmp() work on signed char - fixed.
|
|
|
|
P Removed __chkabort() in fgetc() and fputc() - it's not necessary to poll
|
|
CTRL-C for EVERY character written.
|
|
|
|
B Extraneous semicolon (';') in freopen() deleted.
|
|
|
|
M Changed the code for setting buffer flags in setvbuf().
|
|
|
|
B setvbuf() should set the buffer size ;-) - fixed.
|
|
|
|
S _main() has the commandline as argument INCLUDING the program's name.
|
|
Had to change the interface - easiest way was to rename _main as __submain
|
|
and write a new __submain calling _main. Moved the call to open
|
|
the shared libraries out of the startups, too.
|
|
|
|
S The private library bases now have two '_'.
|
|
|
|
B libm.a needs the private library bases, too.
|
|
|
|
S Some changes for Gerhard's gerlib: All I/O functions now run over
|
|
a unix-alike interface. The standard I/O streams now use fopen.
|
|
|
|
F Added setbuffer() to be able to compile gas1.38 .
|
|
|
|
F changed 'static char *errorlist[]' to 'char *sys_errlist[]' for better
|
|
compatibility. Added 'int sys_nerr' too :-P.
|
|
|
|
F Rewrote documentation & some new chapters in texinfo format.
|
|
|
|
F Changed the directory structure to the distribution form.
|
|
Added a 'distribution' makefile entry.
|
|
|
|
V0.2
|
|
|
|
B Adjusted global makefile for auto detach startups.
|
|
|
|
F specs file added.
|
|
|
|
F The gcc frontend has libgcc.a hardcoded. Added a stub libgcc.a to get
|
|
specs file to work.
|
|
|
|
B gas writes EOF and expects it to be handled as 0xff - fixed.
|
|
|
|
B Symbol redirections didn't work the way I expected - removed most of them.
|
|
|
|
B -lm links libm.a BEFORE libnix. Moved some functions.
|
|
|
|
B vfscanf() does no longer ungetc EOF.
|
|
|
|
M Optimized __udivsi3, __umodsi3, __divsi3, __modsi3, div, ldiv.
|
|
|
|
F Some functions added to libamiga.a.
|
|
|
|
V0.3
|
|
|
|
B strtod() gave a warning - fixed.
|
|
|
|
B strftime() didn't count correctly - fixed.
|
|
|
|
M Optimized atan2, fmod, strlen.
|
|
|
|
B Bug in makefile for the math libraries - fixed.
|
|
|
|
F The low level standard-I/O functions are now posix compliant.
|
|
|
|
F access(), stricmp(), unlink(), fstat(), bcmp() added.
|
|
|
|
V0.4
|
|
|
|
B Fixed bug in fstat().
|
|
|
|
B Bugs in fread() and fwrite() when processing no data at all - fixed.
|
|
|
|
P Added an inline version of strlen() in vfprintf, vsscanf, strxfrm, setlocale.
|
|
|
|
M Rewrote all stub functions as symbol redirections to a single one.
|
|
|
|
F strcasecmp() added.
|
|
|
|
S moved __modsi3, __umodsi3 into the div-equivalents.
|
|
|
|
B A missing locale.library should not cause a program exit - fixed.
|
|
|
|
B asctime used 'c' instead of 'C' - fixed.
|
|
|
|
B strftime didn't work correctly on numbers longer than 2 characters - fixed.
|
|
|
|
B Some additional work on the low level I/O needed.
|
|
|
|
S Did some work on the startups.
|
|
|
|
S The auto-detach startups had some holes. I removed them
|
|
from distribution until I get a better method :'(.
|
|
|
|

|
|
|
|
F Hook and boopsi functions added to libamiga.a.
|
|

|
|
|
|
F Auto-detach reintegrated (clean this time) as an object module.
|
|
|
|
F FastRand and RangeRand added to libamiga.a.

|
|
|

V0.6

F Added a stackswap-module
|
|
|

S Changed stat() to work silently (now suppresses all *DOS* requesters)
|
|
|
|
B Fixed a bug in __swbuf() - overrun buffersize by one character, oops...
|
|
|
|
B __chkabort() didn't clear ctrl-c signal - fixed
|
|
|
|
S signal handling heavily changed - now more unix-like
|
|
|
|
F Added default values to libstubs.a for some by certain modules used variables
|
|
(__stack, _procname, __priority)

|
|
V0.7 (second official release)
|
|
|
|
B fseek didn't clear the EOF flag.
|
|
|
|
S Dropped the ChangeMode call in open(). Now mode "a" files have a shared lock,

but the other method didn't work with all handlers :-(.
|
|
|
|
B Made fread() and fwrite() buffered.
|
|
|
|
S Got rid of those ARexx-scripts when building the library :-). Now you can
|
|
build libnix on a sun using a cross-compiler.
|
|
|
|
B Fixed some holes in the commandline parser that could give empty arguments.
|
|
|
|
F Prepared startups for the third argument of main(int argc,char *argv[],char *env[]).
|
|
It's not supported, but you could now ;-).
|
|
|
|
B Fixed a bug in the floating point part of vprintf (introduced with the last
|
|
revision :-( ).
|
|
|
|
F fileno() and fdtofh() added.
|
|
|
|
F Version string added to ALL the modules - let's see if this hack works :-).
|
|
|
|
V0.8 (third official release)
|
|
|
|
B Fixed the returncode of close(STDIN_FILENO) and errno after lseek().
|
|

B Fixed a bug in atan2().
|
|
|
|
F All libnix requesters now check pr_WindowPtr first.
|
|
|
|

|
|
|
|
V0.9
|
|
|
|
B ANSI demands flushing of line or unbuffered output files write reading from
|
|
line buffered input.
|
|
|
|
B Fixed the bug that wrote weird characters for floats on some machines -
|
|
the system math libraries don't work correct if you open them in alphabetical
|
|
order (like the computer generated libstubs.a did - thanks ls :-( ).
|
|
|
|
M Optimized the commandline parsers and shared library opener.
|
|
|
|
M Removed some unused prototypes in C-files.
|
|
|
|
V1.0
|
|
|
|
B If no characters are read gets() should return NULL. Dropped unnecessary
|
|
ferror() call in fgets by the way.
|
|
|
|
B strtoul() read characters which were invalid for the current base.
|
|
|
|

|
|
|
|
P tweaked string functions and removed some asm versions
|
|
|
|
P updated headers/strsup.h with new string functions
|
|
|
|
F moved all 1.3 compatibility stuff into a separate lib called libnix13.a

|
|
|
|
S added some const qualifiers at several places
|
|
|
|
F tweaked libamiga.a functions
|
|
|

|
|
|

|
|

|
|
|
|
B strftime() formats for date and date/time were swapped
|
|
(apparently this was due to an outdated manpage...)
|
|
|
|
B fixed incorrect types usage with proper system types
|
|
(makes the library better prepared for PPC ;-)
|
|
|
|
P improved memset(), bcopy() and bzero()
|
|
(hopefully ;-)
|
|
|
|
B fixed (harmless?) bug in freopen() open mode handling
|
|
(did only handle rwa[b]+ but not rwa+[b])
|
|
|
|
B fixed append filemode to really write at end of file only
|
|
|
|
S changed fdopen() to be independed from freopen()
|
|

S stdin/stdout/stderr initialization now use fdopen()
|
|
(-> removed freopen()'s stdio open kludge)
|
|
|
|
S adapted chmod() to return success if SetProtection
|
|
fails because source is locked
|
|
|
|
F finally rewrote devinit.c to use GCC 2.7.2.1 features
|
|
(now in sync with libinit.c/libinitr.c)
|
|
|
|
B fixed Makefiles for case sensitives filesystems, cross
|
|
compilation support (dosesn't use ar directly anymore)
|
|
and proper $(MAKE) handling
|
|
|
|
B fixed hole in math/Makefile.in :-(
|

F added a better and more general debug scheme
|
|
|
|
F added gettimeofday() from libnixPPC package

|
|
__request.c -- rewritten in C (Gunther Nikl)
|
|
|
