2013-01-11 Christopher Faylor <me.cygwin2013@cgf.cx>
* DevNotes: Add entry cgf-000021.
* select.cc (select): Unconditionally return when a signal is detected.
(select_stuff::wait): Ditto.
2013-01-11 Corinna Vinschen <corinna@vinschen.de>
* syscalls.cc (rename): Drop handling paths > 32757 chars, emit EINVAL
instead, thus simplifying code allocating and filling pfri. Drop size
and use constant expression in NtSetInformationFile call. Add comments.
Drop redundant test for fs_serial_number and change comment accordingly.
2013-01-11 Thomas Wolff <towo@towo.net>
* fhandler.h (class dev_console): Flag for expanded control sequence.
* fhandler_console.cc (char_command): Supporting cursor style modes.
2013-01-10 Corinna Vinschen <corinna@vinschen.de>
* path.h (path_conv::fs_type): New method.
* syscalls.cc (rename): Check for cross-device situation before
touching anything. Explain why. Workaround NFS bug in call to
NtSetInformationFile(FileRenameInformation).
2013-01-09 Corinna Vinschen <corinna@vinschen.de>
* cygerrno.h: Fix copyright.
* exceptions.cc: Drop comment explaining removed variable.
2013-01-09 Corinna Vinschen <corinna@vinschen.de>
* dcrt0.cc (main_thread_sinit): New inline function. Fix and explain
a stdio initialization issue.
(dll_crt0_1): Call main_thread_sinit rather than __sinit.
2013-01-07 Christopher Faylor <me.cygwin2013@cgf.cx>
* thread.cc (pthread_rwlock::lookup_reader): Remove parameter: always
assume that we're looking for the current thread.
(pthread_rwlock::tryrdlock): Eliminate self variable. Accommodate
change in lookup_reader().
(pthread_rwlock::unlock): Ditto.
(pthread_rwlock::rdlock): Ditto. Move add_reader call after writer
tests to more closely mimic old behavior.
(pthread_rwlock::wrlock): Accommodate change in lookup_reader().
* thread.h ((pthread_rwlock::lookup_reader): Eliminate argument.
2013-01-07 Christopher Faylor <me.cygwin2013@cgf.cx>
* thread.cc (pthread_rwlock::add_reader): Perform new operation here
and return pointer to allocated RWLOCK_READER structure.
(pthread_rwlock::rdlock): Reorganize to reflect new add_reader
functionality.
(pthread_rwlock::tryrdlock): Ditto. Remove unneeded call to
lookup_reader().
* thread.h (pthread_rwlock::RWLOCK_READER::RWLOCK_READER): New
constructor.
(pthread_rwlock::add_reader): Reflect new functionality.
2013-01-03 Christopher Faylor <me.cygwin2013@cgf.cx>
* globals.cc (exit_states): Renumber so that ES_EXIT_STARTING is first,
as intended.
* sigproc.cc (wait_sig): Only stop accepting signals after
exit_state > ES_EXIT_STARTING.
2013-01-03 Christopher Faylor <me.cygwin2013@cgf.cx>
* sigproc.cc (exit_thread): Set thread signal mask so that no signals
are sent to an exiting thread.
2013-01-02 Christopher Faylor <me.cygwin2013@cgf.cx>
* sigproc.cc (no_signals_available): Remove exit_state test since
signals are available in a limited fashion when exiting.
(sig_dispatch_pending): Ditto.
(sig_send): Ditto.
(exit_thread): Rearrange to avoid an unnecessary DuplicateProcess when
exiting.
(wait_sig): Allow special signals when exiting.
2013-01-02 Christopher Faylor <me.cygwin2013@cgf.cx>
* DevNotes: Add entry cgf-000020, relating to previous checkin.
2013-01-02 Christopher Faylor <me.cygwin2013@cgf.cx>
* cygtls.h (_cygtls::signal_exit): Delete from class.
* exception.h (cygwin_exception): New class.
(cygwin_exception::dumpstack): Declare new function.
(cygwin_exception::context): Ditto.
(cygwin_exception::dump_exception): Ditto.
* exceptions.cc (cygwin_exception::dump_exception): Move into
cygwin_exception class. Accommodate new variable names.
(cygwin_exception::dumpstack): Ditto stackdump -> dumpstack.
(exception::handle): Move andreas processing earlier. Defer signal
processing decisions to the signal thread where they belong. Pass
exception information to sig_send via new siginfo_t si_cyg field.
(ctrl_c_handler): Wait for SIGHUP signal to be processed since it could
cause a process exit and we don't want races with thread exit lock.
(signal_exit): Move back here from sigproc.cc. Modify arguments and
remove from sigpacket class. Decide when to dump core based on signal
type.
(sigpacket::process): Handle exiting signals in context of threads
rather than in the signal thread. Signal debugger on non-Windows
signals. Remove setup_signal_exit call.
* sigproc.cc (no_signals_available): Remove argument.
(signal_exit_code): Delete.
(close_my_readsig): Ditto.
(_cygtls::signal_exit): Move to exceptions.cc.
(sigproc_terminate): Don't attempt to terminate signal thread.
(setup_signal_exit): Delete.
(exit_thread): Use new si_cyg entry in siginfo_t.
(sig_send): Just use empty initializer for si. Accommodate change in
no_signals_available argument.
(wait_sig): Remove attempt to "go asynchronous" on process exit.
Delete __SIGEXIT handling. Don't ever exit.
* sigproc.h: Remove __SIGEXIT from signal enum. Renumber.
* include/cygwin/signal.h (siginfo_t): Add si_cyg entry.
