| | | | | | | | | | | | | | | | | strptime(3) confused July with June with the fr_FR locale. 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. PR: kern/141939 Submitted by: Denis Chatelain <denis@tikuts.com> Notes: svn path=/stable/7/; revision=214080

| | | | | | | | | | | | | Fix a bug due to a type conversion from 64 to 32 bits. The side effect of this type conversion is the high bits which were used to indicate if a special character was a literal or special were dropped. As a result, all special character were treated as special, even if they were supposed to be literals. Approved by: mentor (wes@) Notes: svn path=/stable/7/; revision=208366
* MFC r206760: getcwd(3): Clarify that EACCES may or may not be checked.Jilles Tjoelker2010-05-051-3/+11
| | | | | | | | | | | | | | | | | | POSIX permits but does not require checking access on the current and parent directories. Because various programs do not like it if getcwd(3) fails, it seems best to avoid checking access as much as possible. There are various reports in GNATS about this (search for getcwd). Our getcwd(3) implementation first queries the kernel for the pathname directly, which does not check any permissions but sometimes fails, and then falls back to reading all parent directories for the names.

| | | | | | | | | | | | Use thr_once() with once_t controls to initialize various thread_key_t objects used to provide per-thread storage in the RPC code. Almost all of these used double-checking with a dedicated mutex (tsd_lock) to do this before. However, that is not always safe with more relaxed memory orders. There were also other bugs, such as one in __rpc_createrr() that caused a new key to be allocated each time __rpc_createrr() was invoked. Notes: svn path=/stable/7/; revision=205450

| | | | | | | | | | | | | | | | | | | | - The OPSZ macro actually only does the right thing for int32 and int64 operands but not for double and extended double ones. Instead of trying to fix the macro just nuke it and unroll the loops in the correct way though as extended double operands turn out to be the only special case. - For FxTO{s,d,q} the source operand is int64 so rs2 has to be re-decoded after setting type accordingly as it's generally decoded using the low 2 bits as the type, which are 0 for these three instructions. - Similarly, in case of F{s,d,q}TOx the target is int64 so rd has to be re-decoded using not only the operand mask appropriate for int64 but also the correct register number encoding. - Use const where appropriate. - Wrap long lines.
