principle, the current devfs-based cloning facilit makes the current user<->kernel protocol for allocating new pts nodes difficult or impossible to do without leading to resource leaks or race conditions. We tentatively plan to reintroduce ptmx/pts support in FreeBSD 7.1 once a fixed version has settled out in HEAD. People who really want to run with the current code can re-enable it but it will require tweaking conf files and unifdef'ing it. By removing it now before the release, we avoid having to support the current allocation protocol in future releases in order to provide backwards compatibility with older libc's.

or replace (i.e., zdump) the environment after a call to setenv(), putenv() or unsetenv() has been made, a few changes were made. - getenv() will return the value from the new environ array. - setenv() was split into two functions: __setenv() which is most of the previous setenv() without checks on the name and setenv() which contains the checks before calling __setenv(). - setenv(), putenv() and unsetenv() will unset all previous values and call __setenv() on all entries in the new environ array which in turn adds them to the end of the envVars array. Calling __setenv() instead of setenv() is done to avoid the temporary replacement of the '=' in a string with a NUL byte. Some strings may be read-only data. Added more regression checks for clearing the environment array. Replaced gettimeofday() with getrusage() in timing regression check for better accuracy. Fixed an off-by-one bug in __remove_putenv() in the use of memmove(). This went unnoticed due to the allocation of double the number of environ entries when building envVars. Fixed a few spelling mistakes in the comments. Reviewed by: ache Approved by: wes Approved by: re (kensmith)

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.
