* * pinfo.cc (_pinfo::dup_proc_pipe): Make warning more severe by actuallyChristopher Faylor2005-10-191-5/+8
| | | | | | printing it. (_pinfo::alert_parent): Fix comment. Don't send to parent if we are in an exec stub.

| | | | | | | | | | | | | | | | | | | | | | | | | | | cygthread to handle extra argument, throughout. * cygthread.h (cygthread::callproc): Declare new method. (cygthread::cygthread): Add optional length argument to allow copying arguments to executing thread. * cygthread.cc (cygthread::callproc): Define new method. (cygthread::stub): Use callfunc to invoke thread func to allow potentially allocating stack memory which will be returned. (cygthread::simplestub): Ditto. (cygthread::cygthread): Accept arglen argument. Reset ev here prior to activating thread. Wait for ev after activating thread if we're copying contents to the thread. Wait until the end before setting h, to allow thread synchronization. (cygthread::release): Don't reset ev here. Rely on that happening the next time the thread is activated. * pinfo.h (commune_process): Rename declaration from _pinfo::commune_process. * pinfo.cc (commune_process): Ditto for definition. Modify slightly to allow running as a separate cygthread. * sigproc.cc (child_info::sync): Always wait for both subproc_ready and any hProcess if we have a cygwin parent. (talktome): Change argument to be a pointer to siginfo_t. Contiguously allocate whole siginfo_t structure + any needed extra for eventual passing to commune_process thread. (wait_sig): Accommodate change in talktome argument. * pipe.cc (fhandler_pipe::fixup_after_exec): Remove debugging.

| | | | | | | | | | | | instead. (get_exit_lock): New function. Grabs the lock and sets initial exit_state. * exceptions.cc (try_to_debug): Use low_priority_sleep. (sigpacket::process): Avoid handler if this is an exec stub.

Use information from argument rather than reading from another pipe. Synchronize with other process's commune event. (_pinfo::commune_request): Rename from commune_send. Change DWORD to __uint32 in argument. Fill out information in new siginfo_t element and rely on extended operation of sig_send rather than trying to deal with synchronization issues here. Use process handle and read pipe information filled out by sig_send to gather information from the other process. * sigproc.cc (sig_send): Take special action if "communing" to ensure synchronization with the other process and to return information about the other process to the caller. (talktome): Accept a siginfo_t and handle arguments. Read additional information from the signal pipe when _si_commune._si_code has the PICOM_EXTRASTR flag set. (wait_sig): Pass the transmitted siginfo_t struct and the pipe handle to talktome. Close pipe read handle as soon as possible after we detect that we're exiting.
