This patch removes gdb_stdtargerr. There doesn't seem to be a need
for this -- it is always the same as stdtarg, and (I believe) has been
for many years.

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

Instead of having the interpreter code registering observers for the
signal_received observable, add a "signal_received" virtual method to
struct interp. Add a interps_notify_signal_received function that loops
over all UIs and calls the signal_received method on the interpreter.
Finally, add a notify_signal_received function that calls
interps_notify_signal_received and then notifies the observers. Replace
all existing notifications to the signal_received observers with calls
to notify_signal_received.
Before this patch, the CLI and MI code both register a signal_received
observer. These observer go over all UIs, and, for those that have a
interpreter of the right kind, print the stop notifiation.
After this patch, we have just one "loop over all UIs", inside
interps_notify_signal_received. Since the interp::on_signal_received
method gets called once for each interpreter, the implementations only
need to deal with the current interpreter (the "this" pointer).
The motivation for this patch comes from a future patch, that makes the
amdgpu code register an observer to print a warning after the CLI's
signal stop message. Since the amdgpu and the CLI code both use
observers, the order of the two messages is not stable, unless we define
the priority using the observer dependency system. However, the
approach of using virtual methods on the interpreters seems like a good
change anyway, I think it's more straightforward and simple to
understand than the current solution that uses observers. We are sure
that the amdgpu message gets printed after the CLI message, since
observers are notified after interpreters.
Keep the signal_received, even if nothing uses if, because we will be
using it in the upcoming amdgpu patch implementing the warning described
above.

This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

This renames the fields of cli_interp_base::saved_output_files, as
requested by Simon. I tried to choose names that more obviously
reflect what the field is used for. I also added a couple of
comments.

When using the "set logging" commands, cli_interp_base::set_logging
will send gdb_stdlog output (among others) to the tee it makes for
gdb_stdout. However, this has the side effect of also causing logging
to use the pager. This is PR gdb/29787.
This patch fixes the problem by keeping stderr and stdlog separate
from stdout, preserving the rule that only gdb_stdout should page.

Right now, tee_file owns the second stream it writes to. This is done
for the convenience of the users. In a subsequent patch, this will no
longer be convenient, so this patch moves the responsibility for
ownership to the users of tee_file.

CLI redirect uses a global variable, 'saved_output'. However, globals
are generally bad, and there is no need for this one -- it can be a
member of cli_interp_base. This patch makes this change.
|
|
I happened to find a couple of obsolete declarations in cli-interp.h.
This patch removes them. Tested by rebuilding.
|
|
cli_set_logging is declared but not defined. It's probably a leftover
from whenever interpreters were changed to use inheritance. This
patch removes the declaration. Tested by grep and rebuilding.

Currently, when logging is enabled, output will be sent to both a
logfile and standard terminal output. The redirect option sends output
only to the logfile. This includes all debug output.
Add the option to redirect debug output seperately to normal
output, using the cli command:
set logging debugredirect on
By setting this and enabling logging, all output and debug will
be sent to the logfile. The user will still see all output but
no debug output.
This causes a change in behaviour for anyone currently using
logging redirect, as now only output will be redirected. Users
will have to issue the additional command above to also redirect
debug.
Expand ui-redirect.exp cover the changes.
gdb/ChangeLog:
* cli/cli-interp.c (struct saved_output_files): Add saved entry.
(cli_interp_base::set_logging): Check debug_redirect.
* cli/cli-interp.h (set_logging): Add debug_redirect parameter.
* cli/cli-logging.c (debug_redirect): Add static variable.
(pop_output_files): Add default param.
(handle_redirections): Print debug setting.
(show_logging_command): Likewise.
(_initialize_cli_logging): Add debugredirect command.
* interps.c (current_interp_set_logging): Add debug_redirect
parameter.
* interps.h (set_logging): Add debug_redirect parameter.

Instead of using two bools to decide if the files should close when tee_file
is closed, make file one stay open and file two close. This simplifies the
use cases for it.
Inline the make_logging_output into the calling functions (the logic here
looks ugly in order to simplify a later change).
Expand ui-redirect.exp to cover the changes, similar to mi-logging.exp.
gdb/ChangeLog:
* cli/cli-interp.c (cli_interp_base::set_logging): Create tee_file
directly.
* cli/cli-interp.h (make_logging_output): Remove declaration.
* cli/cli-logging.c (make_logging_output): Remove function.
* mi/mi-interp.c (mi_interp::set_logging): Create tee_file
directly.
* ui-file.c (tee_file::tee_file): Remove bools.
(tee_file::~tee_file): Remove deletes.
* ui-file.h (tee_file): Remove bools.
gdb/testsuite/ChangeLog:
* gdb.base/ui-redirect.exp: Test redirection.

While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards. I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.
So, I changed the script to normalize all include guards in gdb. This
patch is the result.
As usual the script is available here:
https://github.com/tromey/gdb-refactoring-scripts
Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.

- The interp->data field disappears, since we can put data in the
interpreter directly now. The "init" method remains in place, but
it now returns void.
- A few places check if the interpreter method is NULL before calling
it, and also check whether the method returns true/false. For some
of those methods, all current implementations always return true.
In those cases, this commit makes the C++-fied method return void
instead and cleans up the callers.
Tested on x86_64 Fedora 23.

This patch gets rid of this hack in mi_set_logging:
/* The tee created already is based on gdb_stdout, which for MI
is a console and so we end up in an infinite loop of console
writing to ui_file writing to console etc. So discard the
existing tee (it hasn't been used yet, and MI won't ever use
it), and create one based on raw_stdout instead. */
By pushing down responsibility for the tee creation to the
interpreter. I.e., pushing the CLI bits out of handle_redirections

This fixes a few leaks that I spotted, and then confirmed with
"valgrind --leak-check=full":

One is fixed by transfering ownership of the log file to the tee. In
pseudo-patch, since the code was moved at the same time:
- out = new tee_file (curr_output, false, logfile.get (), false);
+ out = new tee_file (curr_output, false, logfile.get (), true);
The other is this bit in mi_set_logging:
else
{
+ delete mi->raw_stdout;
I tried to split the leak fixes to a smaller preparatory patch, but
that was difficult exactly because of the tee hack in
handle_redirections -> mi_set_logging.

There's code in the MI interpreter that decides whether a stop should
be sent to MI's console stream. Move this check to the CLI
interpreter code, so that we can reuse it in both the CLI and TUI
interpreters.

2016-06-21 Pedro Alves <palves@redhat.com>
* cli/cli-interp.c: Include gdbthread.h and thread-fsm.h.
(should_print_stop_to_console): New function, factored out from
mi_on_normal_stop_1.
* cli/cli-interp.h (should_print_stop_to_console): Declare.
* mi/mi-interp.c (mi_on_normal_stop_1): Use
should_print_stop_to_console. Pass it the current UI's console
interpreter.
* mi/mi-main.c (captured_mi_execute_command): Use the
INTERP_CONSOLE symbol rather than explicit "console".

All interpreter types (CLI/TUI/MI) print the prompt, and then call
start_event_loop.
Because we'll need an interpreter hook to display the
interpreter-specific prompt before going back to the event loop,
without actually starting an event loop, this patch moves the
start_event_loop call to common code, and replaces the command_loop
hook with a pre_command_look hook, that now just prints the prompt.
Turns out to be a cleanup on its own right anyway.

Due to the way that readline's API works (based on globals), we can
only have one instance of readline in a process. So the goal of this
patch is to only allow editing in the main UI, and make sure that only
one UI calls into readline. Some MI paths touch readline variables
currently, which is bad as that is changing variables that matter for
the main console UI. This patch fixes those.
This actually fixes a nasty bug -- starting gdb in MI mode ("gdb
-i=mi"), and then doing "set editing on" crashes GDB, because MI is
not prepared to use readline:
set editing on
&"set editing on\n"
=cmd-param-changed,param="editing",value="on"
^done
(gdb)
p 1
readline: readline_callback_read_char() called with no handler!
Aborted (core dumped)
The fix for that was to add an interp_proc method to query the
interpreter whether it actually supports editing. New test included.
