2015-03-07Split TRY_CATCH into TRY + CATCHPedro Alves1-4/+8
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.

2015-01-12Append to input history file instead of overwriting itPatrick Palka1-1/+1
This patch makes readline append new history lines to the GDB history file on exit instead of overwriting the entire history file on exit. This change allows us to run multiple simultaneous GDB sessions without having each session overwrite the added history of each other session on exit. Care must be taken to ensure that the history file doesn't get corrupted when multiple GDB processes are trying to simultaneously append to and then truncate it. Safety is achieved in such a situation by using an intermediate local history file to mutually exclude multiple processes from simultaneously performing write operations on the global history file. gdb/ChangeLog: * top.h (gdb_add_history): Declare. * top.c (command_count): New variable. (gdb_add_history): New function. (gdb_safe_append_history): New static function. (quit_force): Call it.

2014-12-15Fix build with Python 3.4 (PR python/16784)Simon Marchi1-1/+1
The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook. I would've changed any user of it, but it seems like nothing is using it, Built-tested with python 2.7.x, 3.3.y and 3.4.z. gdb/ChangeLog: * defs.h (gdb_readline): Constify argument.

2014-11-23Fix the processing of Meta-key commands in TUIPatrick Palka1-1/+12
This patch fixes the annoying bug where key sequences such as Alt_F or Alt_B (go forward or backwards by a word) do not behave promptly in TUI. You have to press a third key in order for the key sequence to register. This is mostly ncurses' fault. Calling wgetch() normally causes ncurses to read only a single key from stdin. However if the key read is the start-sequence key (^[ a.k.a. ESC) then wgetch() reads TWO keys from stdin, storing the 2nd key into an internal FIFO buffer and returning the start-sequence key. The extraneous read of the 2nd key makes us miss its corresponding stdin event, so the event loop blocks until a third key is pressed. This explains why such key sequences do not behave promptly in TUI. To fix this issue, we must somehow compensate for the missed stdin event corresponding to the 2nd byte of a key sequence. This patch achieves this by hacking up the stdin event handler to conditionally execute the readline callback multiple times in a row. This is done via a new global variable, call_stdin_event_handler_again_p, which is set from tui_getc() when we receive a start-sequence key and notice extra pending input in the ncurses buffer. Tested on x86_64-unknown-linux-gnu. gdb/ChangeLog: * event-top.h (call_stdin_event_handler_again_p): Declare. * event-top.c (call_stdin_event_handler_again_p): Define. (stdin_event_handler): Use it. * tui/tui-io.c (tui_getc): Prepare to call the stdin event handler again if there is pending input following a start sequence.
2014-10-29PR python/17372 - Python hangs when displaying help()Pedro Alves1-5/+56
This is more of a readline/terminal issue than a Python one. PR17372 is a regression in 7.8 caused by the fix for PR17072: commit 0017922d0292d8c374584f6100874580659c9973 Author: Pedro Alves <palves@redhat.com> Date: Mon Jul 14 19:55:32 2014 +0100 Background execution + pagination aborts readline/gdb gdb_readline_wrapper_line removes the handler after a line is processed. Usually, we'll end up re-displaying the prompt, and that reinstalls the handler. But if the output is coming out of handling a stop event, we don't re-display the prompt, and nothing restores the handler. So the next input wakes up the event loop and calls into readline, which aborts. ... gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> PR gdb/17072 * top.c (gdb_readline_wrapper_line): Tweak comment. (gdb_readline_wrapper_cleanup): If readline is enabled, reinstall the input handler callback. The problem is that installing the input handler callback also preps the terminal, putting it in raw mode and with echo disabled, which is bad if we're going to call a command that assumes cooked/canonical mode, and echo enabled, like in the case of the PR, Python's interactive shell. Another example I came up with that doesn't depend on Python is starting a subshell with "(gdb) shell /bin/sh" from a multi-line command. Tests covering both these examples are added. The fix is to revert the original fix for PR gdb/17072, and instead restore the callback handler after processing an asynchronous target event. Furthermore, calling rl_callback_handler_install when we already have some input in readline's line buffer discards that input, which is obviously a bad thing to do while the user is typing. No specific test is added for that, because I first tried calling it even if the callback handler was still installed and that resulted in hundreds of failures in the testsuite. gdb/ 2014-10-29 Pedro Alves <palves@redhat.com> PR python/17372 * event-top.c (change_line_handler): Call gdb_rl_callback_handler_remove instead of rl_callback_handler_remove.

2014-05-29Make display_gdb_prompt CLI-only.Pedro Alves1-5/+0
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.

2013-01-22With some changes to how software single-step (SSS) breakpoints arePedro Alves1-0/+3
handled, one of those being to place SSS breakpoints on the breakpoint chain as all other breakpoints, annota1.exp times out with lots and lots of breakpoint-invalid and frame-changed annotations. All those extra annotations are actually unnecessary. For one, SSS breakpoints are internal breakpoints, so the frontend shouldn't care if they were added, removed or changed. Then, there's really no point in emitting "breakpoints-invalid" or "frames-invalid" more than once between times the frontend/user can actually issues GDB commands; the frontend will have to wait for the GDB prompt to refresh its state, so emitting those annotations at most once between prompts is enough. Non-stop or async would complicate this, but no frontend will be using annotations in those modes (one of goes of emacs switching to MI was non-stop mode support, AFAIK). The previous patch reveals there has been an intention in the past to suppress multiple breakpoints-invalid annotations caused by ignore count changes. As the previous patch shows, that's always been broken, but in any case, this patch actually makes it work. The next patch will remove several annotation-specific calls in breakpoint.c in favor of always using the breakpoint modified & friends observers, and that causes yet more of these annotations, because several calls to the corresponding annotate_* functions in breakpoint.c are missing, particularly in newer code. So all in all, here's a simple mechanism that avoids sending the same annotation to the frontend more than once until gdb is ready to accept further commands. Tested on x86_64 Fedora 17. 2013-01-22 Pedro Alves <palves@redhat.com> * annotate.c: Include "inferior.h". (frames_invalid_emitted) (breakpoints_invalid_emitted): New globals. (async_background_execution_p): New function. (annotate_breakpoints_changed, annotate_frames_invalid): Skip emitting the annotation if it has already been emitted. (annotate_display_prompt): New function. * annotate.h (annotate_display_prompt): New declaration. * event-top.c: Include annotate.h. (display_gdb_prompt): Call annotate_display_prompt.
