* Fix multiple thinkos in newlocaleCorinna Vinschen2016-08-151-54/+59
| | | | | | | | | | | | | - Setting the categories strings in tmp_locale short-circuits __loadlocale. Use a new_categories array instead, just as in _setlocale_r. - If we have a base, copy over the *not* defined categories in category_mask in the first place. Rearrange loop accordingly. - Free base right in newlocale. Signed-off by: Corinna Vinschen <corinna@vinschen.de>

* Change loadlocale to fill a __locale_t given as parameterCorinna Vinschen2016-08-1512-88/+87
| | | | | | | | | | | | Don't use global variables. This allows to call loadlocale from the yet to be created newlocale(). Rename _thr_locale_t to __locale_t (these locales are not restricted to threads so the name is misleading). Along these lines, fix _set_ctype to take a __locale_t as parameter.

* Consolidate wctomb/mbtowc calls for POSIX-1.2008Corinna Vinschen2016-08-1531-356/+942
| | | | | | | | | | | | | | | | | | | | | - Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls. - Instead, create array of function for ISO and Windows codepages to point to function which does not require to evaluate the charset string on each call. Create matching helper functions. I.e., __iso_wctomb, __iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the right function pointer now. - Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC. - Drop global __wctomb/__mbtowc vars. - Utilize aforementioned changes in Cygwin to get rid of charset in other, calling functions and simplify the code. - In Cygwin restrict global cygheap locale info to the job performed by internal_setlocale. Use UTF-8 instead of ASCII on the fly in internal conversion functions. - In Cygwin dll_entry, make sure to initialize a TLS area with a NULL _REENT->_locale pointer. Add comment to explain why.

* POSIX-1.2008 per-thread locales, groundwork part 2Corinna Vinschen2016-08-1520-477/+272
| | | | | | | | | Move all locale category structure definitions into setlocale.h and remove other headers in locale subdir. Create inline accessor functions for current category struct pointers and use throughout. Use pointers to "C" locale category structs by default in __global_locale.

* POSIX-1.2008 per-thread locales, groundwork part 1Corinna Vinschen2016-08-1531-484/+610
| | | | | | | | | | | | | | | | Introduce first cut of struct _thr_locale_t used for the locale_t definition. Introduce global instance called __global_locale used by default. Introduce internal inline functions __get_global_locale, __get_locale_r, __get_current_locale. Remove usage of global variables in favor of accessor functions pointing to __global_locale for now. Include all local headers in locale subdir from setlocale.h to get single include for internal locale access. Introduce __CTYPE_PTR macro to replace direct access to __ctype_ptr__ and use throughout in isxxx functions. Signed-off by: Corinna Vinschen <corinna@vinschen.de>

* kill(pid, sig) before waitpid() returns -1 for sig != 0Erik Bray2016-08-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a followup to a report back in 2011 about essentially the same issue: https://cygwin.com/ml/cygwin/2011-04/msg00031.html The same test program in that report demonstrates the issue, but with kill sending any non-zero signal. To reiterate, the problem here is POSIX compliance with respect to sending signals to zombie processes. http://pubs.opengroup.org/onlinepubs/9699919799/functions/kill.html claims: Existing implementations vary on the result of a kill() with pid indicating an inactive process (a terminated process that has not been waited for by its parent). Some indicate success on such a call (subject to permission checking), while others give an error of [ESRCH]. Since the definition of process lifetime in this volume of POSIX.1-2008 covers inactive processes, the [ESRCH] error as described is inappropriate in this case. In particular, this means that an application cannot have a parent process check for termination of a particular child with kill(). (Usually this is done with the null signal; this can be done reliably with waitpid().) In response to the originally issue, this was fixed *specifically* for the case of kill(pid, 0). But my reading of the above is that kill() should return 0 in this case regardless of the signal (modulo permissions, etc.). On Linux, for example, when calling kill with pid of a zombie process the kernel will happily deliver the signal to the relevant task_struct; it will just never be acted on since the task will never run again.

* arc: Fix strcmp for big endian without barrel shifterAnton Kolesov2016-08-111-3/+3
| | | | | | | | | | | | | strcmp.S contained invalid guard for code that used barrel-shifter optional instruction - it was checking for !ARC601 instead of whether barrel shifter is present. While it is true that ARC601 doesn't have barrel shifter, so does some other ARC EM configurations. 2016-07-21 Anton Kolesov <Anton.Kolesov@synopsys.com> * libc/machine/arc/strcmp.S: Fix big endian without barrel shifter.

| | | | | | | | | | Commit d7586cb incorrectly checked only for the new cursor position beyond the old cursor position to decide if we have to correct for user scrolling. Since this situation is handled just fine if the cursor is still visible, only perform the subsequent correction if the cursor is not in the visible console window.

* Open process with PROCESS_QUERY_INFORMATION to fetch mapsCorinna Vinschen2016-08-011-2/+2
| | | | | | | | | | | | | | Commit ba58e5f lowered permission requirements when opening threads and processes to {PROCESS,THREAD}_QUERY_LIMITED_INFORMATION. However, when creating the /proc/<PID>/maps file, the call to VirtualQueryEx requires PROCESS_QUERY_INFORMATION access Note: It seems PROCESS_QUERY_LIMITED_INFORMATION is sufficient starting with Windows 8.1, but this is neither documented on MSDN, nor is it a safe bet. It may have to do with a fixed implementation of the UAC trust levels. Let's better follow the docs for now. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Fix clear screen behaviour of console when user scrolled up or downCorinna Vinschen2016-07-291-1/+21
| | | | | | | | | | We must call SetConsoleCursorPosition prior to SetConsoleWindowInfo, otherwise the scroll bars will not be updated by the OS. Make sure to scroll the console window by just the right amount to have the new cursor position one line after the used console buffer area at the top of the console window, no matter the scroll state.

* Don't raise SIGTTIN from poll/selectCorinna Vinschen2016-07-273-10/+41
| | | | | | | | | | | | | SIGTTIN should be raised when read() is made on a tty in a backgrounded process, but not when it's tested with poll()/select(). I guess poll()/select() does need to call bg_check(), in order to detect the error conditions that notices (that is, if bg_check() returns bg_eof or bg_error, then fd is ready as an error condition exists) so add an optional parameter to fhandler_base::bg_select() to indicate that signals aren't desired.
