* libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-251-0/+2
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. 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. Notes: svn path=/head/; revision=326193

* Back out timegm error check from r272562.Andrey A. Chernov2014-10-071-2/+0
| | | | | | | | | | POSIX treats negative time_t as undefined (i.e. may be valid too, depends on system's policy we don't have) and we don't set EOVERFLOW in mktime/timegm as POSIX requires to surely distinguish -1 return as valid negative time from -1 as error return.

* Add strptime(3) support for %U and %W (take 2)Pedro F. Giffuni2014-09-281-7/+119
| | | | | | | | | | | | | | | | | | | | | | | Add support for the missing POSIX-2001 %U and %W features: the existing FreeBSD strptime code recognizes both directives and validates that the week number lies in the permitted range, but then simply discards the value. Initial support for the feature was written by Paul Green. David Carlier added the initial handling of tm_wday/tm_yday. Major credit goes to Andrey Chernov for detecting much of the brokenness, and rewriting/cleaning most of the code, making it much more robust.

* strptime: add support for %t and %nPedro F. Giffuni2014-06-181-38/+20
| | | | | | | | | | | | | | | | | | Posix strptime() requires support for %t and %n, which were added to the illumos port. Curiously we were skipping white spaces by default in most other cases making %t meaningless. We now skip spaces in the case of the %e specifier as strftime(3) explicitly adds a space for the single digit case.

* strptime(3) confused July with June with the fr_FR locale.Edwin Groothuis2010-05-091-0/+8
| | | | | | | | | | | | | | | | When parsing the month "juillet" (abbr "jul"), %B recognized it as "juin" (abbr "jui") because the full name of the month names is checked at the same time as the abbrevation. The new behaviour checks the full names first before checking the abbrevation names.

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
