Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),

2000-01-27T23:07:25Z

just use _foo() <-- foo(). In the case of a libpthread that doesn't do call conversion (such as linuxthreads and our upcoming libpthread), this is adequate. In the case of libc_r, we still need three names, which are now _thread_sys_foo() <-- _foo() <-- foo(). Convert all internal libc usage of: aio_suspend(), close(), fsync(), msync(), nanosleep(), open(), fcntl(), read(), and write() to _foo() instead of foo(). Remove all internal libc usage of: creat(), pause(), sleep(), system(), tcdrain(), wait(), and waitpid(). Make thread cancellation fully POSIX-compliant. Suggested by: deischen

Add three-tier symbol naming in support of POSIX thread cancellation

points. For library functions, the pattern is __sleep() <-- _libc_sleep() <-- sleep(). The arrows represent weak aliases. For system calls, the pattern is _read() <-- _libc_read() <-- read().

fix tabs lost apparently in copy&paste

Replace memory leaking instances of realloc with non-leaking reallocf.

1998-09-16T04:17:47Z

In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

realpath() should break on looped symlinks.

Part 2 of a failed commit (cvs broke). Original message:

1997-03-13T06:58:46Z

Back out a dubious Lite2 change to "optimise" getcwd() to look at $PWD because it's potentially dangerous (think: symlink races). Move realpath() back to it's original location, and remove getcwd_physical() by renaming it back to getcwd() and zapping the original getcwd wrapper. Noticed by: bde The following commits already happened but the log message got lost: Modified Files: gen/Makefile.inc gen/getcwd.c stdlib/Makefile.inc Removed Files: gen/realpath.3

merge from Lite2 - realpath() now shares a lot of code with getcwd()

and is now in the same file.

Don't attempt to lstat() the POSIXLY invalid empty pathname.

1995-02-25T16:06:07Z

realpath() still accepts "" as an arg and converts it to a canonical pathname for the current directory.
