* Split updatepwd() into two smaller functions. The first one, findpwd(),Stefan Farfeleder2008-02-241-38/+45
| | | | | | | | | | | | | computes the new path and the second one, updatepwd(), updates the variables PWD, OLDPWD and the path used for the pwd builtin according to the new directory. For a logical directory change, chdir() is now called between those two functions, no longer causing wrong values to be stored in PWD etc. if it fails.

| | | | | | | | | | | | | | | | | | | | with the same name exists, delete that directory first, before performing the copy. This ensures that mv(1) across devices follows the semantics of rename(2), as required by POSIX. This change could introduce the potential of data loss, even if the copy fails, violating the atomicity properties of rename(2). This is (mostly) mitigated by first renaming the destination and obliterating it only after a succesfull copy. The above logic also led to the introduction of code that will cleanup the results of a partial copy, if a cross-device copy fails.

* Introduce a way to make pure kernal threads.Julian Elischer2007-10-264-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | kthread_add() takes the same parameters as the old kthread_create() plus a pointer to a process structure, and adds a kernel thread to that process. kproc_kthread_add() takes the parameters for kthread_add, plus a process name and a pointer to a pointer to a process instead of just a pointer, and if the proc * is NULL, it creates the process to the specifications required, before adding the thread to it. All other old kthread_xxx() calls return, but act on (struct thread *) instead of (struct proc *). One reason to change the name is so that any old kernel modules that are lying around and expect kthread_create() to make a process will not just accidentally link. fix top to show kernel threads by their thread name in -SH mode add a tdnam formatting option to ps to show thread names. make all idle threads actual kthreads and put them into their own idled process. make all interrupt threads kthreads and put them in an interd process (mainly for aesthetic and accounting reasons) rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper' man page fixes to follow.

These bugs have existed for some time. - Allow swapout to try each thread in a process individually and then swapin the whole process if any of these fail. This allows us to move most scheduler related swap flags into td_flags. - Keep ki_sflag for backwards compat but change all in source tools to use the new and more correct location of P_INMEM.

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.
