Raw Blame History

2011-11-10 Christopher Faylor <me.cygwin2011@cgf.cx>
Throughout use "have_execed" macro rather than "hExeced" global handle.
Throughout rename _PROC_* to _CH_*.
* child_info.h: Include "pinfo.h".
(child_info_types): Rename _PROC_* -> _CH_* to avoid confusion with
similarly named constants.
(_PROC_*): Delete unneeded aliases.
(PROC_*): Ditto.
(CURR_CHILD_INFO_MAGIC): Ditto.
(cchildren): Define using "pinfo_minimal".
(child_info::set_saw_ctrl_c): Move to
(child_info_spawn::set_saw_ctrl_c): Here.
(child_info_spawn::lock): New field.
(child_info_spawn::hExeced): Ditto.
(child_info_spawn::ev): Ditto.
(child_info_spawn::~child_info_spawn): Move to sigproc.cc.
(child_info_spawn::child_info_spawn): Ditto.
(child_info_spawn::cleanup): Declare new function.
(child_info_spawn::set_saw_ctrl_c): Move to this class. Set flag only
when execed and return true when we have set the flag.
(child_info_spawn::child_info_spawn::signal_myself_exited): New function.
(child_info_spawn::wait_for_myself): Ditto.
(child_info_spawn::has_execed_cygwin): Ditto.
(child_info_spawn::has_execed): Ditto. Replaces "hExeced" test.
(child_info_spawn::operator HANDLE&): New operator.
(child_info_spawn::worker): Define old "spawn_guts" as class member.
(ch_spawn): Declare.
(have_execed): Define.
(have_execed_cygwin): Ditto.
* cygheap.h: Update comment.
* dcrt0.cc (get_cygwin_startup_info): Use _CH_* enums.
(child_info_spawn::handle_spawn): Ditto.
(dll_crt0_0): Ditto.
(multiple_cygwin_problem): Ditto.

(ctrl_c_handler): Reference set_saw_ctrl_c via new ch_spawn global.
* globals.cc (hExeced): Delete.
* pinfo.cc (pinfo::thisproc): Refer to cygheap as ::cygheap for
consistency in handle naming when -DDEBUGGING.
(pinfo::init): Accommodate case where myself.h is known but h0 is
passed in.
(pinfo::pinfo): New constructor for setting up a pinfo passed in by
previous exec'or.
(pinfo::proc_waiter): Don't handle subprocess if we're in the process
of exiting due to an exec of a cygwin process. Don't close
rd_proc_pipe here. Close it when we actually are finished with the
process. Use new ch_spawn.signal_myself_exited function to let exec
stub know that subprocess has exited.
(pinfo::wait): Clarify debugging output.
(pinfo::release): Use "close_h" to close all handles to avoid races.
(winpids::add): Assume that elements of the array do not need to be
zeroed and are properly initialized or suffer problems on
pinfo::release. Don't close hProcess since release does that now.

child_info_spawn can use them.
(pinfo): Inherit from pinfo_minimal.
(pinfo::pinfo): Modify to accommodate new pinfo_minimal.

iterated when the process has not execed. Don't do any cleanup here
since it is now handled in pinfo::release.

(child_info::child_info): Assume that all important fields are properly
initialized and avoid memset().

then set up appropriate fields in the struct.
(child_info_spawn::cleanup): Define new function.
(child_info_spawn::record_children): Specifically test for being execed
here. Fill in pinfo_minimal part of children array.

(PROC_DETACHED_CHILD): Delete.
* spawn.cc (chExeced): Delete.
(child_info_spawn::worker): Rename from spawn_guts. Use elements of
child_info_spawn throughout rather than ch.whatever. Use ::cygheap to
