2016-04-12Eliminate immediate_quitPedro Alves1-9/+0
This finally gets rid of immediate_quit (and surrounding infrustruture), as nothing sets it anymore. gdb_call_async_signal_handler was only necessary in order to handle immediate_quit. We can just call mark_async_signal_handler directly on all hosts now. In turn, we can clean up mingw-hdep.c's gdb_select a bit, as sigint_event / sigint_handler is no longer needed. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * defs.h: Update comments on SIGINT handling.

2016-04-12Fix signal handler/event-loop racesPedro Alves1-1/+31
GDB's core signal handling suffers from a classical signal handler / mainline code race: int gdb_do_one_event (void) { ... /* First let's see if there are any asynchronous signal handlers that are ready. These would be the result of invoking any of the signal handlers. */ if (invoke_async_signal_handlers ()) return 1; ... /* Block waiting for a new event. (...). */ if (gdb_wait_for_event (1) < 0) return -1; ... } If a signal is delivered while gdb is blocked in the poll/select inside gdb_wait_for_event, then the select/poll breaks with EINTR, we'll loop back around and call invoke_async_signal_handlers. However, if the signal handler runs between invoke_async_signal_handlers and gdb_wait_for_event, gdb_wait_for_event will block, until the next unrelated event... The fix is to a struct serial_event, and register it in the set of files that select/poll in gdb_wait_for_event waits on. The signal handlers that defer work to invoke_async_signal_handlers call mark_async_signal_handler, which is adjusted to also set the new serial event in addition to setting a flag, and is thus now is garanteed to immediately unblock the next gdb_select/poll call, up until invoke_async_signal_handlers is called and the event is cleared. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * event-loop.c: Include "ser-event.h". (async_signal_handlers_serial_event): New global. (async_signals_handler, initialize_async_signal_handlers): New functions. (mark_async_signal_handler): Set async_signal_handlers_serial_event. (invoke_async_signal_handlers): Clear async_signal_handlers_serial_event. * event-top.c (async_init_signals): Call initialize_async_signal_handlers.

2015-08-26Replace some xmalloc-family functions with XNEW-family onesSimon Marchi1-6/+5
This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

2015-08-25remote: allow aborting long operations (e.g., file transfers)Pedro Alves1-0/+16
Currently, when remote debugging, if you type Ctrl-C just while the target stopped for an internal event, and GDB is busy doing something that takes a while (e.g., fetching chunks of a shared library off of the target, with vFile, to process ELF headers and debug info), the Ctrl-C is lost. The patch hooks up the QUIT macro to a new target method that lets the target react to the double-Ctrl-C before the event loop is reached, which allows reacting to a double-Ctrl-C even when GDB is busy doing some long operation and not waiting for a stop reply. That end result is: (gdb) c Continuing. ^C ^C Interrupted while waiting for the program. Give up waiting? (y or n) y Quit (gdb) info threads Id Target Id Frame * 1 Thread 11673 0x00007ffff7deb240 in _dl_debug_state () from target:/lib64/ld-linux-x86-64.so.2 (gdb) If, however, GDB is waiting for a stop reply (because the target has been resumed, with e.g., vCont;c), but the target isn't responding, we now get: (gdb) c Continuing. ^C ^C The target is not responding to interrupt requests. Stop debugging it? (y or n) y Disconnected from target. (gdb) info threads No threads. This offers to disconnect, because when we're waiting for a stop reply, there's nothing else we can send the target other than an interrupt request. And if that doesn't work, there's nothing else we can do. The Ctrl-C is presently lost because until we get to a user-visible stop, the SIGINT handler that is installed is the one that forwards the interrupt to the remote side, with the \003 "packet" [1]. But, gdbserver ignores an interrupt request if the program is stopped. Still, even if it didn't, the server can only report back a stop-because-of-SIGINT when the program is next resumed. And it may take a while to actually re-resume the target. [1] - In the old sync days, the remote target would react to a double-Ctrl-C by asking users whether they wanted to give up waiting and disconnect. The code is still there, but it it isn't reacheable on most hosts, which support serial connections in async mode (probably only DJGPP doesn't). Even then, in sync mode, remote.c's SIGINT handler is only installed while the target is resumed, and is removed as soon as the target sends back a stop reply. That means that a Ctrl-C just while GDB is processing an internal event can end up with an odd "Quit" at the prompt instead of "Program stopped by SIGINT". In contrast, in async mode, remote.c's SIGINT handler is set up as long as target_terminal_inferior or target_terminal_ours_for_output are in effect (IOW, until we get a user-visible stop and call target_terminal_ours), so the user shouldn't get back a spurious Quit. However, it's still desirable to be able to interrupt a long-running GDB operation, if GDB takes a while to re-resume the target or get back to the event loop. Tested on x86_64 Fedora 20. gdb/ChangeLog: 2015-08-24 Pedro Alves <palves@redhat.com> * defs.h (maybe_quit): Declare.

2015-08-24Prepare for gnulib updatePedro Alves1-1/+1
After the last gnulib import (Dec 2012), gnulib upstream started replacing mingw's 'struct timeval' with a version with 64-bit time_t, for POSIX compliance: commit f8e84098084b3b53bc6943a5542af1f607ffd477 Author: Bruno Haible <bruno@clisp.org> Date: Sat Jan 28 18:12:10 2012 +0100 sys_time: Override 'struct timeval' on some native Windows platforms. See: https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00372.html However, that results in conflicts with native Winsock2's 'select': select()'s argument http://sourceforge.net/p/mingw-w64/mailman/message/29610438/ ... and libiberty's timeval-utils.h timeval_add/timeval_sub, at the least. We don't really need the POSIX compliance, so this patch prepares us to simply not use gnulib's 'struct timeval' replacement once a more recent gnulib is imported, thus preserving the current behavior, by adding a sys/time.h wrapper header that undefs gnulib's replacements, and including that everywhere instead. The SIZE -> OSIZE change is necessary because newer gnulib's sys/time.h also includes windows.h/winsock2.h, which defines a conflicting SIZE symbol. Cross build-tested mingw-w64 32-bit and 64-bit. Regtested on x86_64 Fedora 20. gdb/ChangeLog: 2015-08-24 Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add common/gdb_sys_time.h. * common/gdb_sys_time.h: New file. * event-loop.c: Include gdb_sys_time.h instead of sys/time.h. * gdb_select.h: Likewise. * gdb_usleep.c: Likewise. * maint.c: Likewise. * mi/mi-main.c: Likewise. * mi/mi-parse.h: Likewise. * remote-fileio.c: Likewise. * remote-m32r-sdi.c: Likewise. * remote.c: Likewise. * ser-base.c: Likewise. * ser-pipe.c: Likewise. * ser-tcp.c: Likewise. * ser-unix.c: Likewise. * symfile.c: Likewise. * symfile.c: Likewise.

2015-05-15Fix gdb.mi/mi-nsmoribund.exp timeoutsPedro Alves1-32/+88
The PPC64 buildbot has been showing timeouts in mi-nsmoribund.exp, like this: (...) -thread-info FAIL: gdb.mi/mi-nsmoribund.exp: thread state: all running except the breakpoint thread (timeout) ... and I can reproduce this on gcc110 (PPC64) on the gcc compile farm. That is, the test sends "-thread-info" to GDB, but GDB never replies back. The problem is that these machines are too fast for gdb. :-) That test has a few threads running the same tight loop, and constantly hitting a thread-specific breakpoint that needs to be stepped over. If threads trip on breakpoints fast enough that linux-nat.c's event pipe associated with SIGCHLD is constantly being written to, even if the stdin file descriptor also has an event to handle, gdb never gets to it. because linux-nat.c's pipe comes first in the set of descriptors served by the poll/select code in the event loop. Fix this by having the event loop serve file event sources in round-robin-like fashion, similarly to how its done in gdb_do_one_event. Unfortunately, the poll and the select variants each need their own fixing. Tested on x86_64 Fedora 20 (poll and select variants), and PPC64 Fedora 18. Fixes the timeout in the PPC64 machine in the compile farm that times out without this, and I won't be surprised if it fixes other random timeouts in other tests. (gdbserver's copy of the event-loop doesn't need this (yet), as it still pushes all ready events to an event queue. That is, it hasn't had 70b66289 merged yet. We should really merge both event-loop.c copies into a single shared file, but that's for another day.) gdb/ChangeLog: 2015-05-15 Pedro Alves <palves@redhat.com> Simon Marchi <simon.marchi@ericsson.com> * event-loop.c (gdb_notifier) <next_file_handler, next_poll_fds_index>: New fields. (get_next_file_handler_to_handle_and_advance): New function. (delete_file_handler): If deleting the next file handler to handle, advance to the next file handler. (gdb_wait_for_event): Bail early if no event fired. Poll file handlers in round-robin fashion.
2015-03-07Split TRY_CATCH into TRY + CATCHPedro Alves1-3/+4
This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

commit 70b66289 (Simplify event-loop core, remove two-step event processing) causes a build failure when compiling GDB with gcc/-O2: gdb/event-loop.c: In function ‘gdb_do_one_event’: gdb/event-loop.c:296:10: error: ‘res’ may be used uninitialized in this function [-Werror=maybe-uninitialized] if (res > 0) ^ GCC isn't realizing that event_source_head can never be > 2 and that therefore 'res' is always initialized in all possible paths.

2015-02-03Simplify event-loop core, remove two-step event processingPedro Alves1-241/+93
Even with the previous patch installed, we'll still see sigall-reverse.exp occasionally fail. The problem is that the event loop's event handling processing is done in two steps: #1 - poll all event sources, and push new event objects to the event queue, until all event sources are drained. #2 - go through the event queue, processing each event object at a time. For each event, call the associated callback, and deletes the event object from the queue. and then bad things happen if between #1 and #2 something decides that events from an event source that has already queued events shouldn't be processed yet. To do that, we either remove the event source from the list of event sources, or clear its "have events" flag. However, if an event for that source has meanwhile already been pushed in the event queue, #2 will still process it and call the associated callback... One way to fix it that I considered was to do something to the event objects already in the event queue when an event source is no longer interesting. But then I couldn't find any good reason for the two-step process in the first place. It's much simpler (and less code) to call the event source callbacks as we poll the sources and find events. Tested on x86-64 Fedora 20, native and gdbserver. gdb/ 2015-02-03 Pedro Alves <palves@redhat.com> * event-loop.c: Don't declare nor define a queue type for gdb_event_p. (event_queue): Delete.

2015-02-03When disabling target async, remove all target event sources from the event loopPedro Alves1-0/+8
The sigall-reverse.exp test occasionally fails with something like this: (gdb) PASS: gdb.reverse/sigall-reverse.exp: send signal TERM continue Continuing. The next instruction is syscall exit_group. It will make the program exit. Do you want to stop the program?([y] or n) FAIL: gdb.reverse/sigall-reverse.exp: continue to signal exit (timeout) FAIL: gdb.reverse/sigall-reverse.exp: reverse to handler of TERM (timeout) FAIL: gdb.reverse/sigall-reverse.exp: reverse to gen_TERM (timeout) This is another event-loop/async related problem exposed by the patch that made 'query' use gdb_readline_wrapper (588dcc3edbde19f9). The problem is that even though gdb_readline_wrapper disables target-async while the secondary prompt is in progress, the record target's async event source is left marked. So when gdb_readline_wrapper nests an event loop to process input, it may happen that that event loop ends up processing a target event while GDB is not really ready for it.

2014-05-29Make display_gdb_prompt CLI-only.Pedro Alves1-4/+2
Enabling target-async by default will require implementing sync execution on top of an async target, much like foreground command are implemented on the CLI in async mode. In order to do that, we will need better control of when to print the MI prompt. Currently the interp->display_prompt_p hook is all we have, and MI just always returns false, meaning, make display_gdb_prompt a no-op. We'll need to be able to know to print the MI prompt in some of the conditions that display_gdb_prompt is called from the core, but not all. This is all a litte twisted currently. As we can see, display_gdb_prompt is really CLI specific, so make the console interpreters (console/tui) themselves call it. To be able to do that, and add a few different observers that the interpreters can use to distinguish when or why the the prompt is being printed: #1 - one called whenever a command is cancelled due to an error. #2 - another for when a foreground command just finished. In both cases, CLI wants to print the prompt, while MI doesn't. MI will want to print the prompt in the second case when in a special MI mode. The display_gdb_prompt call in interp_set made me pause. The comment there reads: /* Finally, put up the new prompt to show that we are indeed here. Also, display_gdb_prompt for the console does some readline magic which is needed for the console interpreter, at least... */ But, that looks very much like a no-op to me currently: - the MI interpreter always return false in the prompt hook, meaning actually display no prompt. - the interpreter used at that point is still quiet. And the console/tui interpreters return false in the prompt hook if they're quiet, meaning actually display no prompt. The only remaining possible use would then be the readline magic. But whatever that might have been, it's not reacheable today either, because display_gdb_prompt returns early, before touching readline if the interpreter returns false in the display_prompt_p hook.
