2005-09-20* dcrt0.cc (do_exit): Only call sigproc_terminate from one location --Christopher Faylor6-21/+45
pinfo::exit. * pinfo.cc (pinfo::exit): Move sigproc_terminate later so that signals can be processed while waiting for hExeced child. (pinfo::maybe_set_exit_code_from_windows): Set exit code from sigExeced if it is non-zero. Set exit_state to ES_EXEC_EXIT prior to waiting for captive process exit code. * exceptions.cc (sigExeced): New global variable. (signal_exit): Remove noreturn attribute from declaration. (signal_exit): Just terminate captive process and return if hExeced on the theory that the exit will be subsequently handled in the main thread. * sigproc.cc (sigproc_terminate): Eliminate test for ES_SIGPROCTERMINATE and use ES_FINAL instead. (sig_send): Use no_signals_available instead of duplicate test. * winsup.h (ES_EXEC_EXIT): New enum. (ES_SIGPROCTERMINATE): Delete.

2005-09-19* sigproc.cc (talktome): Take siginfo_t argument. Don't scan all pids tryingChristopher Faylor2-7/+12

2005-09-19 * include/winsock2.h (SO_EXCLUSIVEADDRUSE): Define.Danny Smith2-0/+6
Thanks to Gisle Vanem <giva at bgnett dot no>
2005-09-19 * include/stdlib.h (strtof): Add prototype. UglifyDanny Smith2-6/+25

2005-09-17* pipe.cc (fhandler_pipe::open): Use 'cfree' to free buffer since it is nowChristopher Faylor2-1/+6
allocated by cmalloc.

follow SUSv3. * include/arpa/inet.h (inet_ntop): Ditto. * include/cygwin/in.h: Include cygwin/socket.h to get socklen_t.
2005-09-16* environ.cc (build_env): Use "kilo"bytes not "mega"bytes. Return immediatelyChristopher Faylor3-2/+11
on error. * spawn.cc (spawn_guts): Set return value to -1 on error from build_env.

(EXITCODE_NOSET): Ditto. * sigproc.cc (no_signals_available): Remove check for hwait_sig. Just rely on my_sendsig. Pass in an argument controlling when it is appropriate to test EXITCODE_SET. (proc_can_be_signalled): Remove checks for myself since this function is never called in that context. (sigproc_init): Pre-initialize my_sendsig to non-zero so that proc_can_be_signalled will know that we expect to be signalable soon. (sig_send): Change debugging output.
2005-09-16* sigproc.cc (no_signals_available): Return true if sending to self from theChristopher Faylor5-14/+16
signal thread. (wait_sig): Correct so that WaitForSingleObject is called when hMainThread is != 0, rather than the reverse. * cygheap.cc (cygheap_fixup_in_child): Clarify potential error message. * fork.cc (fork_copy): Cosmetic change.
2005-09-15* sigproc.cc (wait_sig): Reorganize exit case so that ExitProcess is alwaysChristopher Faylor2-12/+27

2005-09-14.Christopher Faylor1-1/+1
2005-09-14* exceptions.cc (sigtid): Remove declaration.Christopher Faylor8-42/+79

(sigproc_terminate): Use and set exit_state appropriately to determine when to do anything. Send __SIGEXIT to self to control process exit. (sig_send): Use my_sendsig for sending signals. Don't call proc_can_be_signalled for myself since the criteria is now different for sending signals to myself. (wait_sig): Copy myself->sendsig to my_sendsig for future use. Exit signal loop when __SIGEXIT is received. Wait for main thread to exit and use its exit status to actually exit process. * sigproc.h (__SIGEXIT): New enum. * dcrt0.cc (alloc_stack): Eliminate superfluous "return;". * debug.cc (add_handle): Ditto. * devices.in (device::parse): Ditto. * dtable.cc (dtable::vfork_parent_restore): Ditto.

heap. Change fatal error to avoid confusion with cygheap. * spawn.cc (linebuf::finish): New function. (linebuf::add): Cosmetic change. (spawn_guts): Only avoid building windows command line if the program being executed was actually mounted with -X.
