* fork.cc (frok::parent): Call postfork to do all of the manipulation required
prior to calling pinfo::remember.
* pinfo.h (pinfo::set_rd_proc_pipe): Just set pinfo's rd_proc_pipe. Don't
bother setting it to NULL.
* sigproc.cc (child_info_spawn::wait_for_myself): Call postfork to set up
myself for waiting.
* spawn.cc (child_info_spawn::worker): Avoid now-unnecessary global lock.
Consistently test mode rather than chtype when making wr_proc_pipe decisions.
Call postfork() to set up stuff prior to pinfo::remember.
(child_info_spawn::wait_for_myself): Move function to sigproc.cc.
* pinfo.cc (is_toplevel_proc): Delete unneeded variable.
* sigproc.cc (child_info_spawn::wait_for_myself): Move function from header to
here. Do all setup required to properly wait for top-level execed process to
exit.
* spawn.cc (child_info_spawn::worker): Attempt to properly handle _P_DETACH.
Set wr_proc_pipe if top-level process even when execing. Just call
wait_for_myself() to... wait for myself. Don't call cleanup twice.
(dtable::release): "Close" standard handle if appropriate.
* dcrt0.cc (dll_crt0_0): Fix minor switch formatting problem.
* fork.cc (frok::parent): Make minor comment indentation change.
(child_info::rd_proc_pipe): Declare new field.
(child_info::wr_proc_pipe): Ditto.
(child_info::prefork): Declare new function, derived from previous pinfo
version.
* dcrt0.cc (child_info_fork::handle_fork): Close previous wr_proc_pipe when
appropriate and assign new one from passed-in child_info block.
(child_info_spawn::handle_spawn): Assign our wr_proc_pipe handle from passed-in
child_info block.
* fork.cc (child_info::prefork): Define new function.
(frok::child): Clear rd_proc_pipe and wr_proc_pipe so they will not be closed
by the child_info destructor.
(frok::parent): Use child_info prefork handling, outside of retry loop. Set
rd_proc_pipe in child's pinfo after successful CreateProcess. Eliminate
postfork call.
* globals.cc (my_wr_proc_pipe): Define/declare new variable.
* pinfo.cc (pinfo::pending_rd_proc_pipe): Delete.
(pinfo::pending_wr_proc_pipe): Ditto.
(pinfo::prefork): Ditto.
(pinfo::postfork): Ditto.
(pinfo::postexec): Ditto.
(pinfo::wait): Assume that rd_proc_pipe is set up correctly prior to call.
(_pinfo::alert_parent): Replace "wr_proc_pipe" with "my_wr_proc_pipe".
* pinfo.h (_pinfo::_wr_proc_pipe): Delete declaration.
(_pinfo::set_rd_proc_pipe): Define new function.
(pinfo::pending_rd_proc_pipe): Delete declaration.
(pinfo::pending_wr_proc_pipe): Ditto.
(pinfo::prefork): Ditto.
(pinfo::postfork): Ditto.
(pinfo::postexec): Ditto.
(pinfo::wr_proc_pipe): Ditto.
* sigproc.cc (child_info::child_info): Clear rd_proc_pipe and wr_proc_pipe.
(child_info::cleanup): Close rd_proc_pipe and wr_proc_pipe if necessary.
(child_info_fork::child_info_fork): Set forker_finished to NULL by default.
(child_info_spawn::child_info_spawn): Use my_wr_proc_pipe rather than
myself->wr_proc_pipe.
(child_info::sync): Ditto.
(child_info_spawn::cleanup): Call child_info::cleanup.
* spawn.cc (child_info_spawn::worker): Remove call to myself.prefork(). Set
wr_proc_pipe when execing or set up new rd_proc_pipe/wr_proc_pipe via
child_info::prefork when spawning. Remove call to pinfo::postexec. Set
rd_proc_pipe in child pinfo when spawning. Use my_wr_proc_pipe rather than
myself->wr_proc_pipe. Remove call to postfork.
(pinfo::wait): Change some comments.
(pinfo::prefork): Move a comment.
(pinfo::postfork): Set pending_*_pipe variables to NULL if closed.
(pinfo::postexec): Use right name when closing handle.
(_pinfo::alert_parent): Ditto.
* sigproc.h (hold_everything): Remove debugging label.
* mkglobals_h: Ditto for generated globals.h file.
* globals.cc: Use specific NO_GLOBALS_H flag to control inclusion of globals.h.
* winsup.h: Honor NO_GLOBALS_H to control inclusion of globals.h. Make
clear_procimptoken extern inline so that it is only defined when needed.
The GNU ar has "q" aliased to "r", and we generally want this behavior anyways
(replacing rather than always appending), so change our AR_FLAGS definition.
Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* fhandler.h (wait_return): Add overlapped_nullread.
* fhandler.cc (fhandler_base_overlapped::wait_overlapped): Detect zero-byte
read as a special case.
(fhandler_base_overlapped::raw_read): Keep looping when zero-byte read detected
without EOF.
(fhandler_base_overlapped::raw_write): Quiet gcc warning by adding
overlapped_nullread to switch statement even though it will never actually be
hit.
size from start of import RVA table to end of section.
(find_first_notloaded_dll): Take big executables into account. Use
offset and size computation as in hook_or_detect_cygwin, just simpler.
(hook_or_detect_cygwin): Return NULL rather than false througout.
Change computation of required mapping size to take non-gcc compilers
into account. Explain the differences and what we do against them.
Don't alloca buf if fn is NULL. Never use buf if fn is NULL.
Fix name and address in previous ChangeLog entry.
failing condition.
(pinfo::wait): Pass name of function to dup_proc_pipe. Eliminate error check
for dup_proc_pipe since it never actually returned an error.
* pinfo.h (_pinfo::dup_proc_pipe): Add an argument.
* spawn.cc (child_info_spawn::worker): Pass name of function to dup_proc_pipe.
Explain why. Add code to check if a DLL with the same basename but
different path is the same DLL. Bail out if not.
(in_load_after_fork): New static NO_COPY bool to allow to differ
between linked and loaded DLL at fork.
(dll_list::load_after_fork): Set in_load_after_fork accordingly.
(dll_dllcrt0_1): Don't treat DLL as linked if in_load_after_fork is set.
Drop test for in_forkee.
