* Reduce NL_ARGMAX to 4096 to match Linux.Brooks Davis2018-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | NL_ARGMAX is the maximum number of positional arguments supported by printf(3). Prior to r308145 it was declared as 99 and not enforced. r308145 added enforcement and increased the value to 64k. Unfortunately, development versions of PostgreSQL used the system definition to allocate and zero an NL_ARGMAX * 4 sized array on the stack of its snprintf implementation with measurable performance impacts. This has been fixed in new PostgreSQL versions, but it is possible that other programs suffer from this problem. A value of 4096 puts us on par with Linux and is certainly large enough for any reasonable program.

* include: 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=326024

| | | | | | | | | | | | | | * Some values changed in POSIX.1-2001; provide the former value if a program requests compliance to an earlier version of POSIX.

| | | | | | | | | | | | | All the "Minimum Values" (POSIX.1-2008 XBD 13 Headers <limits.h>) are now correct. These should all be exactly as they are in the specification; the possibly higher values we support are announced differently.

| | | | | | | | | | | | | | Implement new sysconf keys. Change the implenentation of _SC_ASYNCHRONOUS_IO in preparation for the next set of changes. Move some limits which had been in <sys/syslimits.h> to <limits.h> where they belong. They had only ever been in syslimits.h to provide for the kernel implementation of the CTL_USER MIB branch, which went away with newsysctl years ago. (There is a #error in <sys/syslimits.h> which I will downgrade in the next commit.) Notes: svn path=/head/; revision=106055

* Reviewed by: bdePeter Dufault1998-03-081-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Changes to support building with _POSIX_SOURCE set to 199309L: 1. Add sys/_posix.h to handle those preprocessor defs that POSIX says have effects when defined before including any header files; 2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE 3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now defined in POSIX. These show up when: _POSIX_SOURCE and _POSIX_C_SOURCE are not set or _POSIX_C_SOURCE is set >= 199309L and vanish when: _POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L. 4. Explain these in man 9 posix4; 5. Include _posix.h and conditionalize on new feature test. Notes: svn path=/head/; revision=34319
