* fix uselocale((locale_t)0) not to modify localeTimo Teräs2015-06-051-3/+1
| | | | | commit 68630b55c0c7219fe9df70dc28ffbf9efc8021d8 made the new locale to be assigned unconditonally resulting in crashes later on.
* eliminate costly tricks to avoid TLS access for current locale stateRich Felker2015-05-161-9/+1
| | | | | | | | | | | | | | | the code being removed used atomics to track whether any threads might be using a locale other than the current global locale, and whether any threads might have abstract 8-bit (non-UTF-8) LC_CTYPE active, a feature which was never committed (still pending). the motivations were to support early execution prior to setup of the thread pointer, to partially support systems (ancient kernels) where thread pointer setup is not possible, and to avoid high performance cost on archs where accessing the thread pointer may be very slow. since commit 19a1fe670acb3ab9ead0fe31859ca7d4fe40dd54, the thread pointer is always available, so these hacks are no longer needed. removing them greatly simplifies the affected code.
* add locale frameworkRich Felker2014-07-021-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | this commit adds non-stub implementations of setlocale, duplocale, newlocale, and uselocale, along with the data structures and minimal code needed for representing the active locale on a per-thread basis and optimizing the common case where thread-local locale settings are not in use. at this point, the data structures only contain what is necessary to represent LC_CTYPE (a single flag) and LC_MESSAGES (a name for use in finding message translation files). representation for the other categories will be added later; the expectation is that a single pointer will suffice for each. for LC_CTYPE, the strings "C" and "POSIX" are treated as special; any other string is accepted and treated as "C.UTF-8". for other categories, any string is accepted after being truncated to a maximum supported length (currently 15 bytes). for LC_MESSAGES, the name is kept regardless of whether libc itself can use such a message translation locale, since applications using catgets or gettext should be able to use message locales libc is not aware of. for other categories, names which are not successfully loaded as locales (which, at present, means all names) are treated as aliases for "C". setlocale never fails. locale settings are not yet used anywhere, so this commit should have no visible effects except for the contents of the string returned by setlocale.
* replace all remaining internal uses of pthread_self with __pthread_selfRich Felker2014-06-101-1/+1
| | | | | | | | | | prior to version 1.1.0, the difference between pthread_self (the public function) and __pthread_self (the internal macro or inline function) was that the former would lazily initialize the thread pointer if it was not already initialized, whereas the latter would crash in this case. since lazy initialization is no longer supported, use of pthread_self no longer makes sense; it simply generates larger, slower code.
