* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* While discussing the new gets_s.c in D12785, ed@ suggested puttingCy Schubert2017-11-031-2/+2
| | | | | | | | | | | | {}'s around the if (c == EOF) block to prevent potential 'trailing else' issues from being introduced when refactoring. As my gets_s() code is based on this, it makes sense to fix the same issue here first here and now, then do an svn copy again to capture this history).

* Make stdio deferred cancel-safe.Konstantin Belousov2017-06-291-7/+10
| | | | | | | | | | | | | | | | | | | | | | | If used with fopen(3)/fdopen(3)-ed FILEs, stdio accurately uses non-cancellable internal versions of the functions, i.e. it seems to be fine with regard to cancellation. But if the funopen(3) and f{r,w}open(3) functions were used to open the FILE, and corresponding user functions create cancellation points (they typically have no other choice), then stdio code at least leaks FILE' lock. The change installs cleanup handler which unlocks FILE. Some minimal restructuring of the code was required to make it use common return place to satisfy hand-rolled pthread_cleanup_pop() requirements.

* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-241-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Evans2000-01-271-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

* Suggested by: Bruce Evans, Jeffrey Hsu, Gary PalmerJames Raynard1996-06-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | Added $Id$'s to files that were lacking them (gpalmer), made some cosmetic changes to conform to style guidelines (bde) and checked against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde) One last code cleanup:- Removed spurious casts in fseek.c and stdio.c. Added missing function argument in fwalk.c. Added missing header include in flags.c and rget.c. Put in casts where int's were being passed as size_t's. Put in missing prototypes for static functions. Changed second args of __sflags() inflags.c and writehook() in vasprintf.c from char * to const char * to conform to prototypes. This directory now compiles with no warnings with -Wall under gcc-2.6.3 and with considerably less warnings than before with the ultra-pedantic script I used for testing. (Most of the remaining ones are due to const poisoning). Notes: svn path=/head/; revision=16586
