src-test2/lib/libc/stdlib/realpath.c, branch release/3.5.0_cvs

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.

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