2023-11-21gdb: Replace gdb::optional with std::optionalLancelot Six1-3/+3
Since GDB now requires C++17, we don't need the internally maintained gdb::optional implementation. This patch does the following replacing: - gdb::optional -> std::optional - gdb::in_place -> std::in_place - #include "gdbsupport/gdb_optional.h" -> #include <optional> This change has mostly been done automatically. One exception is gdbsupport/thread-pool.* which did not use the gdb:: prefix as it already lives in the gdb namespace.

2022-10-19internal_error: remove need to pass __FILE__/__LINE__Pedro Alves1-2/+1
Currently, every internal_error call must be passed __FILE__/__LINE__ explicitly, like: internal_error (__FILE__, __LINE__, "foo %d", var); The need to pass in explicit __FILE__/__LINE__ is there probably because the function predates widespread and portable variadic macros availability. We can use variadic macros nowadays, and in fact, we already use them in several places, including the related gdb_assert_not_reached. So this patch renames the internal_error function to something else, and then reimplements internal_error as a variadic macro that expands __FILE__/__LINE__ itself. The result is that we now should call internal_error like so: internal_error ("foo %d", var); Likewise for internal_warning. The patch adjusts all calls sites. 99% of the adjustments were done with a perl/sed script. The non-mechanical changes are in gdbsupport/errors.h, gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

2022-08-19gdb_do_one_event: use integer test syntaxPatrick Monnerat1-2/+2
Timeout is an int, not a bool.
2022-08-18gdbsupport/event-loop: add a timeout parameter to gdb_do_one_eventPatrick Monnerat1-10/+35
Since commit b2d8657, having a per-interpreter event/command loop is not possible anymore. As Insight uses a GUI that has its own event loop, gdb and GUI event loops have then to be "merged" (i.e.: work together). But this is problematic as gdb_do_one_event is not aware of this alternate event loop and thus may wait forever. A solution is to delegate GUI events handling to the gdb events handler. Insight uses Tck/Tk as GUI and the latter offers a "notifier" feature to implement such a delegation. The Tcl notifier spec requires the event wait function to support a timeout parameter. Unfortunately gdb_do_one_event does not feature such a parameter. This timeout cannot be implemented externally with a gdb timer, because it would become an event by itself and thus can cause a legitimate event to be missed if the timeout is 0. Tcl implements "idle events" that are (internally) triggered only when no other event is pending. For this reason, it can call the event wait function with a 0 timeout quite often. This patch implements a wait timeout to gdb_do_one_event. The initial pending events monitoring is performed as before without the possibility to enter a wait state. If no pending event has been found during this phase, a timer is then created for the given timeout in order to re-use the implemented timeout logic and the event wait is then performed. This "internal" timer only limits the wait time and should never be triggered. It is deleted upon gdb_do_one_event exit. The new parameter defaults to "no timeout" (-1): as it is used by Insight only, there is no need to update calls from the gdb source tree.
2022-05-16Reindent gdbsupport/event-loop.cc:handle_file_eventPedro Alves1-54/+50
The handle_file_event function has a few unnecessary {} lexical blocks, presumably because they were originally if blocks, and the conditions were removed, or something along those lines. Remove the unnecessary blocks, and reindent. Change-Id: Iaecbe5c9f4940a80b81dbbc42e51ce506f6aafb2
2022-05-16gdbsupport/event-loop.cc: simplify !HAVE_POLL pathsPedro Alves1-61/+27
gdbsupport/event-loop.cc throughout handles the case of use_poll being true on a system where HAVE_POLL is not defined, by calling internal_error if that situation ever happens. Simplify this by moving the "use_poll" global itself under HAVE_POLL, so that it's way more unlikely to ever end up in such a situation. Then, move the code that checks the value of use_poll under HAVE_POLL too, and remove the internal_error calls. Like, from: if (use_poll) { #ifdef HAVE_POLL // poll code #else internal_error (....); #endif /* HAVE_POLL */ } else { // select code } to #ifdef HAVE_POLL if (use_poll) { // poll code } else #endif /* HAVE_POLL */ { // select code } While at it, make use_poll be a bool. The current code is using unsigned char most probably to save space, but I don't think it really matters here.

2021-12-04gdbsupport: fix memory leak in create_file_handler when re-using file handlerSimon Marchi1-7/+6
ASan made me notice a memory leak, where the memory tied to the file handle name string wasn't freed. When register a file handler with an fd that is already registered, we re-use the file_handler object, so we ended up creating a new std::string object and overwriting the file_handler::name pointer, without free-ing the old std::string. Fix this by allocating file_handler with new, deleting it with delete, and making file_handler::name not a pointer. Change-Id: Ie304cc78ab5ae5dfad9a1366e9890c09de651f43

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-5/+5
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

In GDB, each UI used to get its own unique number, until commit cbe256847e19 ("Remove ui::num"). Re-introduce this field, and use it to make a unique name for the handler. I'm not too sure what goes on in ser-base.c, all I know is that it's what is used when debugging remotely. I've just named the main handler "serial". It would be good to have unique names there too. For instance when debugging with two different remote connections, we'd ideally want the handlers to have unique names. I didn't do it in this patch though. gdb/ChangeLog: * async-event.c (initialize_async_signal_handlers): Pass name to add_file_handler * event-top.c (ui_register_input_event_handler): Likewise. * linux-nat.c (linux_nat_target::async): Likewise. * run-on-main-thread.c (_initialize_run_on_main_thread): Likewise * ser-base.c (reschedule): Likewise. (ser_base_async): Likewise. * tui/tui-io.c: Likewise. * top.h (struct ui) <num>: New field. * top.c (highest_ui_num): New variable. (ui::ui): Initialize num. gdbserver/ChangeLog: * linux-low.cc (linux_process_target::async): Pass name to add_file_handler. * remote-utils.cc (handle_accept_event): Likewise. (remote_open): Likewise. gdbsupport/ChangeLog: * event-loop.h (add_file_handler): Add "name" parameter. * event-loop.cc (struct file_handler) <name>: New field. (create_file_handler): Add "name" parameter, assign it to file handler. (add_file_handler): Add "name" parameter. Change-Id: I9f1545f73888ebb6778eb653a618ca44d105f92c
2020-09-24gdb: remove file_handler typedefSimon Marchi1-12/+23
