pseudo signal to process group instead of just calling
init_console_handler.
* sigproc.cc (wait_sig): Call init_console_handler here on __SIGSETPGRP
signal.
* sigproc.h (__SIGSETPGRP): Define.
* include/cygwin/wait.h: Use new __wait_status_to_int()
macro to access status value in W*() status checks.
Fix status description.
* include/sys/wait.h: Allow `int' and `union wait' as
wait status parameter. Change __wait_status_to_int()
macro and wait () prototypes accordingly. Add inline
functions for C++. Remove extra `;'.
environment pointer as parameter and return pointer to corresponding
win32 environment block if != NULL. Otherwise just sync as before.
(cygwin_internal): Add CW_CVT_ENV_TO_WINENV case.
* include/cygwin/version.h: Bump API minor number.
* include/sys/cygwin.h (cygwin_getinfo_types): Add CW_CVT_ENV_TO_WINENV.
memcpy function optimized for the cortex-a15.
* libc/machine/arm/memcpy-stub.c: New file.
* libc/machine/arm/Makefile.am (lib_a_SOURCES): Add memcpy-stub.c,
memcpy.S.
* libc/machine/arm/Makefile.in: Regenerate.
if Attaching to a process with the trace-children flag set.
(handle_output_debug_string): Apparently we don't need to explicitly
attach for debugging when a child process starts
* Makefile.in (strace.exe): Link with ntdll
a given DLL name. Change default search path to allow /usr/bin.
(get_full_path_of_dll): Find DLLs even if the caller used a ".so"
suffix or a "lib" prefix for the DLL.
field.
(class lockf_t): Add lf_ver field.
(lockf_t::lockf_t): Initialize lf_ver to 0.
(class inode_t): Change i_wait to i_cnt. Change comment to explain
change in usage.
(inode_t:use): Rename from wait. Make private.
(inode_t::unuse): Rename from unwait. Make private.
(inode_t::inuse): Rename from waiting. Make private.
(inode_t::notused): New public method to set use count to 0.
(inode_t::unlock_and_remove): New method to unlock node and to delete
it if it's unused in current process.
(fhandler_base::del_my_locks): Drop global list lock. Drop variable
no_locks_left. Simpify unlocking and removing node by just calling
unlock_and_remove.
(fixup_lockf_after_exec): Call notused method for each node.
(inode_t::get): Call use method. Lock node only if outside of list
lock.
(inode_t::get_all_locks_list): Accommodate additional lf_ver field
when creating lockf_t structure from object name.
(lockf_t::create_lock_obj_attr): Accommodate additional lf_ver field
when creating object name from lockf_t structure. Handle
STATUS_OBJECT_NAME_COLLISION gracefully in F_POSIX case as well.
Change comment accordingly. Increment lf_ver field rather than high
byte of lf_wid field. Simplify comment.
(fhandler_disk_file::lock): Always call unlock_and_remove rather than
just UNLOCK on node.
(lf_setlock): Move ret definition where it's used. Drop unneeded
tests for obj being not NULL. Only check for deadlock condition if the
lock we're trying to establish is a POSIX lock. Revamp object
collecting and wait code to cover all cases. Don't return with EDEADLK
if blocking process can't be opened for synchronization in F_POSIX case,
rather just wait like in F_FLOCK case. Change system_printf to
debug_printf in that case. Only run WaitForMultipleObjects with high
priority. Close obj and process handles prior to locking node.
(fhandler_base::close): Move call to del_my_locks from here...
* fhandler_disk_file.cc (fhandler_disk_file::open): ...to here.
* flock.cc (struct lockfattr_t): New type.
(lockf_t::close_lock_obj): New method, use throughout.
(lockf_t::create_lock_obj_attr): New method.
(lockf_t::create_lock_obj): Use create_lock_obj_attr method. Handle
STATUS_OBJECT_NAME_COLLISION in F_FLOCK case gracefully. Add lengthy
comments to explain why and how.
(lockf_t::open_lock_obj): Use create_lock_obj_attr method.
(lockf_t::del_lock_obj): Call NtSetEvent rather than SetEvent for
symmetry.
(fhandler_disk_file::lock): Define n only where it's used. Call
need_fork_fixup only if call was successful. Handle EINTR and
ECANCELED return values from lf_setlock.
(lf_setlock): Drop WAIT_UNLOCKED and WAIT_PROC_EXITED. Don't wait
for event object handle count to become <= 1 in F_LOCK case.
Simplify WFMO return value handling. Don't handle signal and cancel
events here; just return with appropriate error code instead.
(lf_getblock): Ignore locks for which the handle can't be opened.
Use IsEventSignalled.
* ntdll.h (STATUS_INVALID_INFO_CLASS): Undef if defined elsewhere to
make sure the definition is casted to NTSTATUS.
(STATUS_INVALID_HANDLE): Define and ditto.
(STATUS_OBJECT_NAME_COLLISION): Define.
(NtSetEvent): Declare.
FILE_OVERWITE/FILE_OVERWRITE_IF. Set file size to 0 explicitely if
regular, existing file has been opened for writing with O_TRUNC flag
set. Explain why.
sigprocmask to copy parent thread signal mask into new parent_sigmask
member.
(pthread::thread_init_wrapper): Copy _my_tls.sigmask from new
parent_sigmask member.
* thread.h (class pthread): Drop parent_tls. Add parent_sigmask.
* libc/posix/regexec.c: Define "nope" only #ifndef NDEBUG.
* libc/stdio/vfscanf.c: Define "state" only #ifdef _MB_CAPABLE.
* libc/string/wcwidth.c: Include <wctypes.h> for "iswprint" and
"iswcntrl".
* libc/string/index.c: Include <strings.h> for "index".
* libc/string/rindex.c: Include <strings.h> for "rindex".
* libc/string/strcasecmp.c: Include <strings.h> for "strcasecmp".
Don't include <string.h>.
* libc/string/strncasecmp.c: Include <strings.h> for "strncasecmp".
Don't include <string.h>.
* libc/string/bzero.c: Include <strings.h> for "bzero".
Don't include <string.h>
* libc/misc/ffs.c: Include <strings.h> for "ffs".
Don't include <_ansi.h>.
