ee8f97394e Check return value for setenv() 2007-11-06 10:35:50 +00:00
Sean Farley
2966d28c32 Significantly reduce the memory leak as noted in BUGS section for 
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

ba174a5e38 Back out all POSIXified *env() changes. 
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

97e49dd4b5 Eliminate error with -W* strict flags and make putenv() calls conforming to 
standard and portable in the same way as f.e. gcc internal portable code does.

231a973125 Speed up hardlink detection by using a self-sizing hash 
table rather than the old linear list search.

On my "hardlink detection torture test", this reduced
user time from 4700 seconds down to 4.2 seconds
and wallclock time from 1:24:48 down to 1:08.
(Yes, that's over one THOUSAND times reduction in user time. ;-)
In the worst case, the new code doubles peak memory usage,
though it could actually reduce memory usage in many cases.

1aa8a0a95b * add a -c option which displays the grand total of all files 
counted.

 * re-word parts of the man page which I felt were badly worded
   or ambiguous.

 * change the behaviour of argument processing so that when more
   than one of the -P, -H and -L options are specified it will
   print an error message, rather than choosing the last option
   specified, this behaviour is more logical and consistent with
   other utilities.

 * change the behaviour of argument processing so that negative
   arguments to the -d option are not allowed.
