* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-11/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579

* Simplify sytem call renaming. Instead of _foo() <-- _libc_foo <-- foo(),Jason Evans2000-01-271-5/+5
| | | | | | | | | | | | | | | | | | | | 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.

* Implement the weak aliases for private entry points in the inet_*John Polstra1998-09-021-1/+10
| | | | | | | | | | | | | | and res_* modules in a way that works for ELF. I moved the aliases out of res_stubs.c and into the individual modules where the entry points are defined. Weak aliases don't work in ELF unless that is the case. (Actually, I'm surprised it worked for a.out.) This should fix the undefined "inet_addr" and related symbols in various applications that fail to include <arpa/inet.h> or <resolv.h> as they are supposed to do.

* Resolve some unexpected differences when comparing with the 2.2 version.Peter Wemm1998-05-021-2/+10
| | | | | | | | | One bug was relatively harmless (select's timeout had an uninitialized tv_usec), the other I'm not so sure.. (neglected to catch select returns less than zero). Both of these were irrelevant on kernels with poll(). Notes: svn path=/head/; revision=35624
* Update libc dns code to 4.9.7-T1B level. This involved chopping out largePeter Wemm1998-05-021-2/+43
| | | | | | | | | chunks of res_comp.c and replacing it with chunks of bind-8.1.1's resolver code. (There are no interface changes though) The other parts are better bounds checking related. Notes: svn path=/head/; revision=35623
* Some adjustments for the resolver use of poll(). For some reason I thoughtPeter Wemm1997-09-161-7/+8
| | | | | | | | | | an unimplemented syscall returned ENOSYS, rather than EINVAL. I have run statically linked code with this wrapper and it does appear to work fine on 2.2-stable which doesn't have poll(). ktrace shows the poll syscall fail once and the fallback to select() working. Notes: svn path=/head/; revision=29488
* Call poll(2) from within the resolver but adapt to older kernels without itPeter Wemm1997-09-141-26/+68
| | | | | | | | | | | | | | | | if necessary. This removes the need to malloc large fd_set's for selecting on high fd's (larger than FD_SETSIZE at libc compile time). The syscall adaptive stuff only happens on the very first call. SIGSYS is masked, and if the call to poll fails with ENOSYS, then we use select for the life of the program. If poll does not fail with ENOSYS, then we always use poll and skip the once-off signal masking gunk. This may be overkill, but it saved my neck a few times while working on multiple different sets of kernel sources, some with poll, some without. Notes: svn path=/head/; revision=29380
* replace the OpenBSD fd_set sizing code with something more efficient.Peter Wemm1997-06-281-9/+16
| | | | | | | | | | Only call malloc() if the fd is too big for the compiled in fd_set size, and don't use calloc either. This should reduce the impact of conflicts with private malloc implementations etc. When using the fd_set on the stack, only zero what is needed rather than all 1024 bits like FD_ZERO did.
