* struct tm.tm_year is listed as 'years since 1900', and is signed. OnPeter Wemm2004-08-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | 64 bit systems, years roughly -2^31 through 2^31 can be represented in time_t without any trouble. 32 bit time_t systems only range from roughly 1902 through 2038. As a consequence, none of the date munging code for all the various calendar tweaks before then is present. There are other problems including the fact that there was no 'year zero' and so on. So rather than get excited about trying to figure out when the calendar jumped by two weeks etc, simply disallow negative (ie: prior to 1900) years. This happens to have an important side effect. If you bzero a 'struct tm', it corresponds to 'Jan 0, 1900, 00:00 GMT'. This happens to be representable (after canonification) in 64 bit time_t space. Zero tm structs are generally an error and mktime normally returns -1 for them. Interestingly, it tries to canonify the 'jan 0' to 'dec 31, 1899', ie: year -1. This conveniently trips the negative year test above, which means we can trivially detect the null 'tm' struct. This actually tripped up code at work. :-/ (Don't ask) Notes: svn path=/head/; revision=134231

* Replace rev 1.33 with a real fix. The problem was integer overflowsPeter Wemm2002-12-021-8/+2
| | | | | | | | | | | | | | | | | | | when trying to store the year in a signed int. The maximum time_t on ia64 is around 292 billion years in the future, but 'int' and struct tm.tm_year can only represent then ext 2.1 billion years or so. This solves the problem of mktime/localtime looping on ia64. Unfortunately, the standards say that tm_year is an 'int', so we are still stuck with a y2147483647 bug. bash2's configure script looks for bugs in mktime() and fails on ia64 because of this. However, mktime() on FreeBSD fails the test normally anyway so this is no big loss. This change does not affect any other platforms besides ia64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here are the diffs for libc_r to get it one step closer to P1003.1c These make most of the thread/mutex/condvar structures opaque to the user. There are three functions which have been renamed with _np suffixes because they are extensions to P1003.1c (I did them for JAVA, which needs to suspend/resume threads and also start threads suspended). I've created a new header (pthread_np.h) for the non-POSIX stuff. The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented doesn't work. I think its best to delete it. I don't think libc_r needs tags anyway, 'cause most of the source is in libc which does have tags. also: Here's the first batch of man pages for the thread functions. The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was inherited from /usr/src/lib/libc/Makefile that should only be done with libc. also: I should have sent this diff with the pthread(3) man page. It allows people to type make -DWANT_LIBC_R world to get libc_r built with the rest of the world. I put this in the pthread(3) man page. The default is still not to build libc_r. also: The diff attached adds a pthread(3) man page to /usr/src/share/man/man3. The idea is that without libc_r installed, this man page will give people enough info to know that they have to build libc_r. Notes: svn path=/head/; revision=17706
