| * Revert recent change for Bug#8855.Paul Eggert2012-11-241-3/+0
| | | | | | | | | | | | | | | | As reported by Harald Hanche-Olsen in <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00445.html> the change introduces a further bug, of creating lots of zombie processes in some cases. Further work is needed to come up with a better fix for Bug#8855.

(sys_wait): Remove prototype. * nt/config.nt (HAVE_SYS_WAIT_H): Define to 1. * src/w32proc.c (create_child): Don't clip the PID of the child process to fit into an Emacs integer, as this is no longer a restriction. (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by reaping only the process specified by PID argument, if that is positive. Use PID instead of dead_child to know which process to reap. Wait for the child to die only if WNOHANG is not in OPTIONS. (sys_select): Don't set dead_child. * src/sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion, as it is no longer needed. * src/process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions, no longer needed. (record_child_status_change): Remove the setting of record_at_most_one_child for the !WNOHANG case. 2012-11-03 Paul Eggert <eggert@cs.ucla.edu> Fix a race condition that causes Emacs to mess up glib (Bug#8855). This is a backport from the trunk. The symptom is a diagnostic "GLib-WARNING **: In call to g_spawn_sync(), exit status of a child process was requested but SIGCHLD action was set to SIG_IGN and ECHILD was received by waitpid(), so exit status can't be returned." The diagnostic is partly wrong, as the SIGCHLD action is not set to SIG_IGN. The real bug is a race condition between Emacs and glib: Emacs does a waitpid (-1, ...) and reaps glib's subprocess by mistake, so that glib can't find it. Work around the bug by invoking waitpid only on subprocesses that Emacs itself creates. * src/process.c (create_process, record_child_status_change): Don't use special value -1 in pid field, as the caller now must know the pid rather than having the callee infer it. The inference was sometimes incorrect anyway, due to another race. (create_process): Set new 'alive' member if child is created. (process_status_retrieved): New function. (record_child_status_change): Use it. Accept negative 1st argument, which means to wait for the processes that Emacs already knows about. Move special-case code for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of processes that have already been waited for, by testing and clearing new 'alive' member. (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change now does this internally. (handle_child_signal): Let record_child_status_change do all the work, since we do not want to reap all exited child processes, only the child processes that Emacs itself created. * src/process.h (Lisp_Process): New boolean member 'alive'.
* | Fix a recently-introduced delete-process race condition.Paul Eggert2012-12-051-0/+6
| | | | | | | | | | | | | | | | | | * callproc.c, process.h (record_kill_process): New function, containing part of the old call_process_kill. (call_process_kill): Use it. This does not change call_process_kill's behavior. * process.c (Fdelete_process): Use record_kill_process to fix a race condition that could cause Emacs to lose track of a child.
* | Don't let call-process be a zombie factory.Paul Eggert2012-12-031-17/+0

As a side effect, this change also fixes a longstanding rare race condition whereby Emacs could mistakenly kill unrelated processes, and it fixes a bug where a second C-g does not kill a recalcitrant synchronous process in GNU/Linux and similar platforms. The patch should also fix the last vestiges of Bug#9488, a bug which has mostly been fixed on the trunk by other changes. * callproc.c, process.h (synch_process_alive, synch_process_death) (synch_process_termsig, sync_process_retcode): Remove. All uses removed, to simplify analysis and so that less consing is done inside critical sections. * callproc.c (call_process_exited): Remove. All uses replaced with !synch_process_pid. * callproc.c (synch_process_pid, synch_process_fd): New static vars. These take the role of what used to be in unwind-protect arg. All uses changed. (block_child_signal, unblock_child_signal): New functions, to avoid races that could kill innocent-victim processes. (call_process_kill, call_process_cleanup, Fcall_process): Use them. (call_process_kill): Record killed processes as deleted, so that zombies do not clutter up the system. Do this inside a critical section, to avoid a race that would allow the clutter. (call_process_cleanup): Fix code so that the second C-g works again on common platforms such as GNU/Linux. (Fcall_process): Create the child process in a critical section, to fix a race condition. If creating an asynchronous process, record it as deleted so that zombies do not clutter up the system. Do unwind-protect for WINDOWSNT too, as that's simpler in the light of these changes. Omit unnecessary call to emacs_close before failure, as the unwind-protect code does that. * callproc.c (call_process_cleanup): * w32proc.c (waitpid): Simplify now that synch_process_alive is gone. * process.c (record_deleted_pid): New function, containing code refactored out of Fdelete_process. (Fdelete_process): Use it. (process_status_retrieved): Remove. All callers changed to use child_status_change. (record_child_status_change): Remove, folding its contents into ... (handle_child_signal): ... this signal handler. Now, this function is purely a handler for SIGCHLD, and is not called after a synchronous waitpid returns; the synchronous code is moved to wait_for_termination. There is no need to worry about reaping more than one child now. * sysdep.c (get_child_status, child_status_changed): New functions. (wait_for_termination): Now takes int * status and bool interruptible arguments, too. Do not record child status change; that's now the caller's responsibility. All callers changed. Reimplement in terms of get_child_status. (wait_for_termination_1, interruptible_wait_for_termination): Remove. All callers changed to use wait_for_termination. * syswait.h: Include <stdbool.h>, for bool. (record_child_status_change, interruptible_wait_for_termination): Remove decls. (record_deleted_pid, child_status_changed): New decls. (wait_for_termination): Adjust to API changes noted above. Fixes: debbugs:12980

* lisp.h: Fix a problem with aliasing and vector headers.Paul Eggert2011-04-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 4.6.0 optimizes based on type-based alias analysis. For example, if b is of type struct buffer * and v of type struct Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size != &v->size, and therefore "v->size = 1; b->size = 2; return v->size;" must therefore return 1. This assumption is incorrect for Emacs, since it type-puns struct Lisp_Vector * with many other types. To fix this problem, this patch adds a new type struct vector_header that documents the constraints on layout of vectors and pseudovectors, and helps optimizing compilers not get fooled by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons. * lisp.h (XVECTOR_SIZE): New convenience macro. All previous uses of XVECTOR (foo)->size replaced to use this macro, to avoid the hassle of writing XVECTOR (foo)->header.size. (XVECTOR_HEADER_SIZE): New macro, for use in XSETPSEUDOVECTOR. (XSETTYPED_PVECTYPE): New macro, specifying the name of the size member. (XSETPVECTYPE): Rewrite in terms of new macro. (XSETPVECTYPESIZE): New macro, specifying both type and size. This is a bit clearer, and further avoids the possibility of undesirable aliasing. (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size. (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XVECTOR_HEADER_SIZE. (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE, since Lisp_Subr is a special case (no "next" field). (ASIZE): Rewrite in terms of XVECTOR_SIZE. (struct vector_header): New type. (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the object, to help avoid aliasing. (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP. (SUBRP): Likewise, since Lisp_Subr is a special case. * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table): (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector): (struct Lisp_Hash_Table): Combine first two members into a single struct vector_header member. All uses of "size" and "next" members changed to be "header.size" and "header.next". * buffer.h (struct buffer): Likewise. * font.h (struct font_spec, struct font_entity, struct font): Likewise. * frame.h (struct frame): Likewise. * process.h (struct Lisp_Process): Likewise. * termhooks.h (struct terminal): Likewise. * window.c (struct save_window_data, struct saved_window): Likewise. * window.h (struct window): Likewise. * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector): Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems. * buffer.c (init_buffer_once): Likewise. * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a special case. * process.c (Fformat_network_address): Use local var for size, for brevity.
