3947f654ea gdb: make add_com_alias accept target as a cmd_list_element
The alias creation functions currently accept a name to specify the
target command.  They pass this to add_alias_cmd, which needs to lookup
the target command by name.

Given that:

 - We don't support creating an alias for a command before that command
   exists.
 - We always use add_info_alias just after creating that target command,
   and therefore have access to the target command's cmd_list_element.

... change add_com_alias to accept the target command as a
cmd_list_element (other functions are done in subsequent patches).  This
ensures we don't create the alias before the target command, because you
need to get the cmd_list_element from somewhere when you call the alias
creation function.  And it avoids an unecessary command lookup.  So it
seems better to me in every aspect.

gdb/ChangeLog:

	* command.h (add_com_alias): Accept target as
	cmd_list_element.  Update callers.

2f822da535 gdb: generate the prefix name for prefix commands on demand
Previously, the prefixname field of struct cmd_list_element was manually
set for prefix commands.  This seems verbose and error prone as it
required every single call to functions adding prefix commands to
specify the prefix name while the same information can be easily
generated.

Historically, this was not possible as the prefix field was null for
many commands, but this was fixed in commit
3f4d92ebdf by Philippe Waroquiers, so
we can rely on the prefix field being set when generating the prefix
name.

This commit also fixes a use after free in this scenario:
* A command gets created via Python (using the gdb.Command class).
  The prefix name member is dynamically allocated.
* An alias to the new command is created. The alias's prefixname is set
  to point to the prefixname for the original command with a direct
  assignment.
* A new command with the same name as the Python command is created.
* The object for the original Python command gets freed and its
  prefixname gets freed as well.
* The alias is updated to point to the new command, but its prefixname
  is not updated so it keeps pointing to the freed one.

gdb/ChangeLog:

	* command.h (add_prefix_cmd): Remove the prefixname argument as
	it can now be generated automatically.  Update all callers.
	(add_basic_prefix_cmd): Ditto.
	(add_show_prefix_cmd): Ditto.

	(add_prefix_cmd_suppress_notification): Ditto.
	(add_abbrev_prefix_cmd): Ditto.
	* cli/cli-decode.h (struct cmd_list_element): Replace the
	prefixname member variable with a method which generates the
	prefix name at runtime.  Update all code reading the prefix
	name to use the method, and remove all code setting it.
	* python/py-cmd.c (cmdpy_destroyer): Remove code to free the
	prefixname member as it's now a method.
	(cmdpy_function): Determine if the command is a prefix by
	looking at prefixlist, not prefixname.

edeaceda7b gdb: startup commands to control Python extension language
Add two new commands to GDB that can be placed into the early
initialization to control how Python starts up.  The new options are:

  set python ignore-environment on|off
  set python dont-write-bytecode auto|on|off

  show python ignore-environment
  show python dont-write-bytecode

These can be used from GDB's startup file to control how the Python
extension language behaves.  These options are equivalent to the -E
and -B flags to python respectively, their descriptions from the
Python man page:

  -E     Ignore environment variables like PYTHONPATH and PYTHONHOME
         that modify the  behavior  of  the  interpreter.

  -B     Don't write .pyc files on import.

041ca48e97 gdb: extension languages finish_initialization to initialize
Now that both Python and Guile are fully initialized from their
respective finish_initialization methods, the "finish" in the method
name doesn't really make sense; initialization starts _and_ finishes
with that method.

As such, this commit renames finish_initialization to just initialize.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* extension-priv.h (struct extension_language_ops): Rename
	'finish_initialization' to 'initialize'.
	* extension.c (finish_ext_lang_initialization): Renamed to...
	(ext_lang_initialization): ...this, update comment, and updated
	the calls to reflect the change in struct extension_language_ops.

8e3685bf25 gdb: delay python initialisation until gdbpy_finish_initialization
Delay Python initialisation until gdbpy_finish_initialization.

This is mostly about splitting the existing gdbpy_initialize_*
functions in two, all the calls to register_objfile_data_with_cleanup,
gdbarch_data_register_post_init, etc are moved into new _initialize_*
functions, but everything else is left in the gdbpy_initialize_*
functions.

Then the call to do_start_initialization (in python/python.c) is moved
from the _initialize_python function into gdbpy_finish_initialization.

There should be no user visible changes after this commit.

	* python/py-arch.c (_initialize_py_arch): New function.
	(gdbpy_initialize_arch): Move code to _initialize_py_arch.

ba6a0ef349 gdb: use make_scoped_restore to restore gdbpy_current_objfile
The current mechanism by which the Python gdb.current_objfile is
maintained does not allow for nested auto-load events.  It is assumed
that once an auto-load script has finished loading then the current
objfile should be set back to NULL.  In a nested situation, we should
be restoring the previous value.

We already have an RAII class to handle save/restore type behaviour,
so lets just switch to use that.

The test is a little contrived, but is simple enough, and triggers the
bug.  The real use case might involve the auto-load script calling
functions (either in the just-loaded object file, or in the main
executable), which in turn trigger further auto-loads to occur.

gdb/ChangeLog:

	* python/python.c (gdbpy_source_objfile_script): Use
	make_scoped_restore to restore gdbpy_current_objfile.
	(gdbpy_execute_objfile_script): Likewise.

2708dbbd58 gdb/python: reformat an error string
While working on another patch I noticed an oddly formatted error
message in the Python code.

When 'set python print-stack message' is in effect then consider this
Python script:

  class TestCommand (gdb.Command):
      def __init__ (self):
          gdb.Command.__init__ (self, "test-cmd", gdb.COMMAND_DATA)
      def invoke(self, args, from_tty):
          raise RuntimeError ("bad")
  TestCommand ()

And this GDB session:

  (gdb) source path/to/python/script.py
  (gdb) test-cmd
  Python Exception <class 'RuntimeError'> bad:
  Error occurred in Python: bad

The line 'Python Exception <class 'RuntimeError'> bad:' doesn't look
terrible in this situation, the colon at the end of the first line
makes sense given the second line.

However, there are places in GDB where there is no second line
printed, for example consider this python script:

  def stop_listener (e):
      raise RuntimeError ("bad")
  gdb.events.stop.connect (stop_listener)

Then this GDB session:

  (gdb) file helloworld.exe
  (gdb) start
  Temporary breakpoint 1 at 0x40112a: file hello.c, line 6.
  Starting program: helloworld.exe

  Temporary breakpoint 1, main () at hello.c:6
  6	  printf ("Hello World\n");
  Python Exception <class 'RuntimeError'> bad:
  (gdb) si
  0x000000000040112f	6	  printf ("Hello World\n");
  Python Exception <class 'RuntimeError'> bad:

In this case there is no auxiliary information displayed after the
warning, and the line ending in the colon looks weird to me.

A quick survey of the code seems to indicate that it is not uncommon
for there to be no auxiliary information line printed, its not just
the one case I found above.

I propose that the line that currently looks like this:

  Python Exception <class 'RuntimeError'> bad:

Be reformatted like this:

  Python Exception <class 'RuntimeError'>: bad

I think this looks fine then in either situation.  The first now looks
like this:

  (gdb) test-cmd
  Python Exception <class 'RuntimeError'>: bad
  Error occurred in Python: bad

And the second like this:

  (gdb) si
  0x000000000040112f	6	  printf ("Hello World\n");
  Python Exception <class 'RuntimeError'>: bad

There's just two tests that needed updating.  Errors are checked for
in many more tests, but most of the time the pattern doesn't care
about the colon.

gdb/ChangeLog:

	* python/python.c (gdbpy_print_stack): Reformat an error message.

gdb/testsuite/ChangeLog:

	* gdb.python/py-framefilter.exp: Update expected results.
	* gdb.python/python.exp: Update expected results.

dda83cd783 gdb, gdbserver, gdbsupport: fix leading space vs tabs issues
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).

0f767f942b gdb/python: Add gdb.Architecture.registers method
This commit adds a new method gdb.Architecture.registers that returns
an object of the new type gdb.RegisterDescriptorIterator.  This
iterator returns objects of the new type gdb.RegisterDescriptor.

A RegisterDescriptor is not a way to read the value of a register,
this is already covered by Frame.read_register, a RegisterDescriptor
is simply a way to discover from Python, which registers are
available for a given architecture.

I did consider just returning a string, the name of each register,
instead of a RegisterDescriptor, however, I'm aware that it we don't
want to break the existing Python API in any way, so if I return just
a string now, but in the future we want more information about a
register then we would have to add a second API to get that
information.  By going straight to a descriptor object now, it is easy
to add additional properties in the future should we wish to.

Right now the only property of a register that a user can access is
the name of the register.

In future we might want to be able to ask the register about is
register groups, or its type.

c47bae859a Fix Python3.9 related runtime problems
Python3.9b1 is now available on Rawhide.  GDB w/ Python 3.9 support
can be built using the configure switch -with-python=/usr/bin/python3.9.

Attempting to run gdb/Python3.9 segfaults on startup:

    #0  0x00007ffff7b0582c in PyEval_ReleaseLock () from /lib64/libpython3.9.so.1.0
    #1  0x000000000069ccbf in do_start_initialization ()
	at worktree-test1/gdb/python/python.c:1789
    #2  _initialize_python ()
	at worktree-test1/gdb/python/python.c:1877
    #3  0x00000000007afb0a in initialize_all_files () at init.c:237
    ...

Consulting the the documentation...

https://docs.python.org/3/c-api/init.html

...we find that PyEval_ReleaseLock() has been deprecated since version
3.2.  It recommends using PyEval_SaveThread or PyEval_ReleaseThread()
instead.  In do_start_initialization, in gdb/python/python.c, we
can replace the calls to PyThreadState_Swap() and PyEval_ReleaseLock()
with a single call to PyEval_SaveThread.   (Thanks to Keith Seitz
for working this out.)

With that in place, GDB gets a little bit further.  It still dies
on startup, but the backtrace is different:

    #0  0x00007ffff7b04306 in PyOS_InterruptOccurred ()
       from /lib64/libpython3.9.so.1.0
    #1  0x0000000000576e86 in check_quit_flag ()

	gdbarch=0x0, language=0x0)
	at worktree-test1/gdb/python/python.c:211
    #4  0x0000000000686e00 in python_new_inferior (inf=0xddeb10)
	at worktree-test1/gdb/python/py-inferior.c:251
    #5  0x00000000005d9fb9 in std::function<void (inferior*)>::operator()(inferior*) const (__args#0=<optimized out>, this=0xccad20)
	at /usr/include/c++/10/bits/std_function.h:617

    #8  0x00000000005dbcb8 in initialize_inferiors ()
	at worktree-test1/gdb/inferior.c:947
    ...

We checked with some Python Developers and were told that we should
acquire the GIL prior to calling any Python C API function.  We
definitely don't have the GIL for calls of PyOS_InterruptOccurred().

I moved class_gdbpy_gil earlier in the file and use it in
gdbpy_check_quit_flag() to acquire (and automatically release) the
GIL.

With those changes in place, I was able to run to a GDB prompt.  But,
when trying to quit, it segfaulted again due to due to some other
problems with gdbpy_check_quit_flag():

    Thread 1 "gdb" received signal SIGSEGV, Segmentation fault.
    0x00007ffff7bbab0c in new_threadstate () from /lib64/libpython3.9.so.1.0
    (top-gdb) bt 8
    #0  0x00007ffff7bbab0c in new_threadstate () from /lib64/libpython3.9.so.1.0
    #1  0x00007ffff7afa5ea in PyGILState_Ensure.cold ()
       from /lib64/libpython3.9.so.1.0
    #2  0x000000000069b58c in gdbpy_gil::gdbpy_gil (this=<synthetic pointer>)
	at worktree-test1/gdb/python/python.c:278
    #3  gdbpy_check_quit_flag (extlang=<optimized out>)
	at worktree-test1/gdb/python/python.c:278
    #4  0x0000000000576e96 in check_quit_flag ()
	at worktree-test1/gdb/extension.c:776
    #5  0x000000000057700c in restore_active_ext_lang (previous=0xe9c050)
	at worktree-test1/gdb/extension.c:729
    #6  0x000000000088913a in do_my_cleanups (
	pmy_chain=0xc31870 <final_cleanup_chain>,
	old_chain=0xae5720 <sentinel_cleanup>)
	at worktree-test1/gdbsupport/cleanups.cc:131
    #7  do_final_cleanups ()
	at worktree-test1/gdbsupport/cleanups.cc:143

In this case, we're trying to call a Python C API function after
Py_Finalize() has been called from finalize_python().  I made
finalize_python set gdb_python_initialized to false and then cause
check_quit_flag() to return early when it's false.

With these changes in place, GDB seems to be working again with
Python3.9b1.  I think it likely that there are other problems lurking.
I wouldn't be surprised to find that there are other calls into Python
where we don't first make sure that we have the GIL.  Further changes
may well be needed.

I see no regressions testing on Rawhide using a GDB built with the
default Python version (3.8.3) versus one built using Python 3.9b1.

I've also tested on Fedora 28, 29, 30, 31, and 32 (all x86_64) using
the default (though updated) system installed versions of Python on
those OSes.  This means that I've tested against Python versions
2.7.15, 2.7.17, 2.7.18, 3.7.7, 3.8.2, and 3.8.3.  In each case GDB
still builds without problem and shows no regressions after applying
this patch.

0fa7617d84 Mark move constructors as "noexcept"
I recently learned that move constructors generally should be marked
"noexcept".  This ensures that standard containers will move objects
when possible, rather than copy them.

This patch fixes the cases I could find.  Note that implicitly-defined
or defaulted move constructors will automatically do what you'd
expect; that is, they are noexcept if all the members have noexcept
move constructors.

While doing this, I noticed a couple of odd cases where the move
constructor seemed to assume that the object being constructed could
have state requiring destruction.  I've fixed these as well.  See
completion_result and scoped_mmap.

08feed99cb Change get_objfile_arch to a method on objfile
This changes get_objfile_arch to be a new inline method,
objfile::arch.

To my surprise, this function came up while profiling DWARF psymbol
reading.  Making this change improved performance from 1.986 seconds
to 1.869 seconds.  Both measurements were done by taking the mean of
10 runs on a fixed copy of the gdb executable.

0743fc83c0 Replace most calls to help_list and cmd_show_list
Currently there are many prefix commands that do nothing but call
either help_list or cmd_show_list.  I happened to notice that one such
call, for "set print type", used the wrong command list parameter,
causing incorrect output.

Rather than fix this bug in isolation, I decided to eliminate this
possibility by adding two new ways to add prefix commands, which
simply route the call to help_list or cmd_show_list, as appropriate.
This makes it impossible for a mismatch to occur.

In some cases, a bit of output was removed; however, I don't think
this output in general was very useful.  It seemed redundant with
what's already printed by help_list.  A representative example is this
hunk, removed from ada-lang.c:

-  printf_unfiltered (_(\
-"\"set ada\" must be followed by the name of a setting.\n"));

This simplified the CLI style set/show commands quite a bit, and
allowed the deletion of a macro.

This also cleans up some unusual code in windows-tdep.c.

Tested on x86-64 Fedora 30.  Note that I have no way to build the
go32-nat.c change.

Information about the deprecated function can be found here:

https://docs.python.org/3.9/whatsnew/3.9.html#deprecated

Specifically, with regard to PyEval_InitThreads(), it says:

    The PyEval_InitThreads() and PyEval_ThreadsInitialized() functions
    are now deprecated and will be removed in Python 3.11.  Calling
    PyEval_InitThreads() now does nothing.  The GIL is initialized by
    Py_Initialize() since Python 3.7.  (Contributed by Victor Stinner
    in bpo-39877.)

I chose to disable the call with a #if test using PY_VERSION_HEX.
There is precedent for use of PY_VERSION_HEX; it's used in two places
in python-internal.h.  I noticed that under certain circumstances
python-internal.h defines PyEval_InitThreads to be nothing, which
accomplishes the same thing.  I considered doing something similar for
this case, but decided against it because, at some point in the future,
the presence of PyEval_InitThreads() without some explanation will be
confusing to a reader who won't be able to find PyEval_InitThreads in
the current (future for us) Python API.  IMO, use of the #if along
with an accompanying comment seemed more straightforward.

gdb/ChangeLog:

	* python/python.c (do_start_initialization): Don't call
	PyEval_InitThreads for Python 3.9 and beyond.

1ba1ac8801 gdb: Enable stdin on exception in execute_gdb_command
This is an update of this patch:

  https://sourceware.org/ml/gdb-patches/2018-09/msg00884.html

This patch attempts to address PR gdb/23718 by re-enabling stdin
whenever an exception is caught during gdb.execute().

When Python gdb.execute() is called, an exception could occur (e.g. the
target disappearing), which is then converted into a Python exception.  If
stdin was disabled before the exception is caught, it is not re-enabled,
because the exception doesn't propagate to the top level of the event loop,
whose catch block would otherwise enable it.

The result is that when execution of a Python script completes, GDB does
not prompt or accept input, and is effectively hung.

This change rectifies the issue by re-enabling stdin in the catch block of
execute_gdb_command, prior to converting the exception to a Python
exception.

Since this patch was originally posted I've added a test, and also I
converted the code to re-enable stdin from this:

  SWITCH_THRU_ALL_UIS ()
    {
      async_enable_stdin ();
    }

to simply this:

  async_enable_stdin ();

My reasoning is that we only need the SWITCH_THRU_ALL_UIS if, at the time
the exception is caught, the current_ui might be different than at the time
we called async_disable_stdin.  Within python's execute_gdb_command I think
it should be impossible to switch current_ui, so the SWITCH_THRU_ALL_UIS
isn't needed.

gdb/ChangeLog:

	PR gdb/23718
	* gdb/python/python.c (execute_gdb_command): Call
	async_enable_stdin in catch block.

f6474de9aa Allow use of Pygments to colorize source code
While GNU Source Highlight is good, it's also difficult to build and
distribute.  For one thing, it needs Boost.  For another, it has an
unusual configuration and installation setup.

Pygments, a Python library, doesn't suffer from these issues, and so I
thought it would be a reasonable fallback.

This patch implements this idea.  GNU Source Highlight is preferred,
but if it is unavailable (or fails), the extension languages are
tried.  This patch also implements support for Pygments.

Something similar could be done for Guile, using:

    https://dthompson.us/projects/guile-syntax-highlight.html

However, I don't know enough about Guile internals to make this
happen, so I have not done it here.

ff47f4f06d Fix valgrind error from gdb.decode_line
PR symtab/12535 points out that gdb.decode_line("") will cause a
valgrind report.

I think the empty linespec does not really make sense.  So, this patch
changes gdb.decode_line to treat a whitespace-only linespec the same
as a non-existing argument.

6b3661116e gdb: add declaration to Python init function
When I try to enable -Wmissing-declarations, I get this error:

      CXX    python/python.o
    /home/smarchi/src/binutils-gdb/gdb/python/python.c: In function ‘PyObject* init__gdb_module()’:
    /home/smarchi/src/binutils-gdb/gdb/python/python.c:1582:1: error: no previous declaration for ‘PyObject* init__gdb_module()’ [-Werror=missing-declarations]
     init__gdb_module (void)
     ^~~~~~~~~~~~~~~~

Prevent it by providing a declaration just before the definition.

gdb/ChangeLog:

	* python/python.c (init__gdb_module): Add declaration.

6c2659886f gdb: add back declarations for _initialize functions
I'd like to enable the -Wmissing-declarations warning.  However, it
warns for every _initialize function, for example:

      CXX    dcache.o
    /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
    /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
     _initialize_dcache (void)
     ^~~~~~~~~~~~~~~~~~

The only practical way forward I found is to add back the declarations,
which were removed by this commit:

    commit 481695ed5f
    Author: John Baldwin <jhb@FreeBSD.org>
    Date:   Sat Sep 9 11:02:37 2017 -0700

        Remove unnecessary function prototypes.

I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

470c0b1c9a gdb: Introduce global_symbol_searcher
Introduce a new class to wrap up the parameters needed for the
function search_symbols, which has now become a member function of
this new class.

The motivation is that search_symbols already takes a lot of
parameters, and a future commit is going to add even more.  This
commit hopefully makes collecting the state required for a search
easier.

As part of this conversion the list of filenames in which to search
has been converted to a std::vector.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* python/python.c (gdbpy_rbreak): Convert to using
	global_symbol_searcher.
	* symtab.c (file_matches): Convert return type to bool, change
	file list to std::vector, update header comment.
	(search_symbols): Rename to...
	(global_symbol_searcher::search): ...this and update now its
	a member function of global_symbol_searcher.  Take account of the
	changes to file_matches.
	(symtab_symbol_info): Convert to using global_symbol_searcher.
	(rbreak_command): Likewise.
	(search_module_symbols): Likewise.
	* symtab.h (enum symbol_search): Update comment.
	(search_symbols): Remove declaration.
	(class global_symbol_searcher): New class.

971db5e21e Use run_on_main_thread in gdb.post_event
This changes gdb.post_event to use the new run_on_main_thread
function.  This is somewhat tricky because the Python GIL must be held
while manipulating reference counts.

The problem seems to be created by gdbpy_enter::~gdbpy_enter () releasing the GIL lock
too early:
~gdbpy_enter () does:
      ...
      PyGILState_Release (m_state);
      python_gdbarch = m_gdbarch;
      python_language = m_language;

      restore_active_ext_lang (m_previous_active);
    }

So, it releases the GIL lock, does 2 assignments and then leads to the following
call sequence:
  restore_active_ext_lang => check_quit_flag => python.c gdbpy_check_quit_flag
     => PyOS_InterruptOccurred => is_main.
is_main code is:
    static int
    is_main(_PyRuntimeState *runtime)
    {
        unsigned long thread = PyThread_get_thread_ident();
        PyInterpreterState *interp = _PyRuntimeState_GetThreadState(runtime)->interp;
        return (thread == runtime->main_thread
                && interp == runtime->interpreters.main);
    }

The macros and functions to access the thread state are documented as:
    /* Variable and macro for in-line access to current thread
       and interpreter state */

    #define _PyRuntimeState_GetThreadState(runtime) \
        ((PyThreadState*)_Py_atomic_load_relaxed(&(runtime)->gilstate.tstate_current))

    /* Get the current Python thread state.

       Efficient macro reading directly the 'gilstate.tstate_current' atomic
       variable. The macro is unsafe: it does not check for error and it can
       return NULL.

       The caller must hold the GIL.

       See also PyThreadState_Get() and PyThreadState_GET(). */
    #define _PyThreadState_GET() _PyRuntimeState_GetThreadState(&_PyRuntime)

So, we see that GDB releases the GIL and then potentially calls
_PyRuntimeState_GetThreadState that needs the GIL.

It is not very clear why the problem is only observed when running under
Valgrind.  Probably caused by the slowdown due to Valgrind and/or to the 'single
thread' scheduling by Valgrind.

This patch fixes the crashes by releasing the GIT lock later.

	* python/python.c (gdbpy_enter::~gdbpy_enter): Release GIL after
	restore_active_ext_lang, as GIL is needed for (indirectly)
	called PyOS_InterruptOccurred.

c9d95fa3d0 Replace the MSYMBOL_*_NAME macros with member functions
Improves readability. In the future, it will also allow making the name
private, once the name setter functions become member functions.

086baaf134 gdb/python: Introduce gdb.lookup_static_symbols
If gdb.lookup_static_symbol is going to return a single symbol then it
makes sense (I think) for it to return a context sensitive choice of
symbol, that is the global static symbol that would be visible to the
program at that point.

However, if the user of the python API wants to instead get a
consistent set of global static symbols, no matter where they stop,
then they have to instead consider all global static symbols with a
given name - there could be many.  That is what this new API function
offers, it returns a list (possibly empty) of all global static
symbols matching a given name (and optionally a given symbol domain).

gdb/ChangeLog:

	* python/py-symbol.c (gdbpy_lookup_static_symbols): New
	function.
	* python/python-internal.h (gdbpy_lookup_static_symbols):
	Declare new function.
	* python/python.c (python_GdbMethods): Add
	gdb.lookup_static_symbols method.
	* NEWS: Mention gdb.lookup_static_symbols.

gdb/testsuite/ChangeLog:

	* gdb.python/py-symbol.exp: Add test for
	gdb.lookup_static_symbols.

gdb/doc/ChangeLog:

	* python.texi (Symbols In Python): Add documentation for
	gdb.lookup_static_symbols.

This simplifies memory management. I've also changed some global variables
to std::string accordingly (which store the result of these functions),
but not all because some are used with add_setshow_optional_filename_cmd
which requires a char*.

e4df087431 Fix leak detected in python.c initialization code.
Valgrind reports the below leak.
Make the variable progname_copy static, so that Valgrind continues
to find a pointer to the memory given to Python.
Note that the comment in do_start_initialization and the Python documentation
indicates that the progname given to Py_SetProgramName cannot be freed.
However, in Python 3.7.4, Py_SetProgramName does:
void
Py_SetProgramName(const wchar_t *program_name)
{
    ...
    PyMem_RawFree(_Py_path_config.program_name);
    _Py_path_config.program_name = _PyMem_RawWcsdup(program_name);

So, it looks like 3.7.4 Python duplicates its argument, which explains
the leak found by Valgrind.
It looks better to respect the doc and not have GDB freeing the string
given to Py_SetProgramName, and avoid the leak error by declaring
the progname_copy static.
This will work with Python versions that really use this string without
duplicating it, and avoids a leak report for Python version that duplicates
it.

4acfdd20c9 gdb: Add new -n flag to some info commands
The 'info variables', its alias 'whereis', and 'info functions' all
include non-debug symbols in the output by default.  The list of
non-debug symbols can sometimes be quite long, resulting in the
debug symbol based results being scrolled off the screen.

This commit adds a '-n' flag to all of the commands listed above that
excludes the non-debug symbols from the results, leaving just the
debug symbol based results.

272044897e Make GDB compile with Python 3 on MinGW
PyFile_FromString and PyFile_AsFile have been removed in Python 3.
There is no obvious replacement that works here, and we can't just
pass our FILE* to a DLL in Windows because it may use a different
C runtime.

So we just call a Python function which reads and executes file
contents. Care must be taken to execute it in the context of
__main__.

Tested by inverting the ifdef and running the testsuite on Debian
Linux (even without the patch, I failed at running the testsuite
on Windows). I did test with both Python 2 and 3.

268a13a5a3 Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the
top level.

This patch just renames the "common" directory.  The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top.  This approach makes the patches a bit
more tractable.

I chose the name "gdbsupport" for the directory.  However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

Tested by the buildbot.

5af5392a3d Fix crash when using PYTHONMALLOC=debug (PR python/24742)
This bug was originally reported against Fedora GDB:

  https://bugzilla.redhat.com/show_bug.cgi?id=1723564

The problem is that GDB will crash in the following scenario:

- PYTHONMALLOC=debug or PYTHONDEVMODE=1 is set.

- The Python debuginfo is installed.

- GDB is used to debug Python.

The crash looks like this:

  $ PYTHONMALLOC=debug gdb -args python3 -c pass
  GNU gdb (GDB) Fedora 8.3-3.fc30
  Reading symbols from python3...
  Reading symbols from /usr/lib/debug/usr/bin/python3.7m-3.7.3-3.fc30.x86_64.debug...
  (gdb) run
  Starting program: /usr/bin/python3 -c pass
  Missing separate debuginfos, use: dnf debuginfo-install glibc-2.29-9.fc30.x86_64
  Debug memory block at address p=0x5603977bf330: API ''
      8098648152243306496 bytes originally requested
      The 7 pad bytes at p-7 are not all FORBIDDENBYTE (0xfb):
	  at p-7: 0x03 *** OUCH
	  at p-6: 0x00 *** OUCH
	  at p-5: 0x00 *** OUCH
	  at p-4: 0x00 *** OUCH
	  at p-3: 0x00 *** OUCH
	  at p-2: 0x00 *** OUCH
	  at p-1: 0x00 *** OUCH
      Because memory is corrupted at the start, the count of bytes requested
	 may be bogus, and checking the trailing pad bytes may segfault.
      The 8 pad bytes at tail=0x706483999ad1f330 are Segmentation fault (core dumped)

It's hard to determine what happens, but after doing some
investigation and talking to Victor Stinner I found that GDB should
not use the Python memory allocation functions before the Python
interpreter is initialized (which makes sense).  However, we do just
that on python/python.c:do_start_initialization:

  ...
  progsize = strlen (progname.get ());
  progname_copy = (wchar_t *) PyMem_Malloc ((progsize + 1) * sizeof (wchar_t));
  ...
  /* Note that Py_SetProgramName expects the string it is passed to
     remain alive for the duration of the program's execution, so
     it is not freed after this call.  */
  Py_SetProgramName (progname_copy);
  ...
  Py_Initialize ();
  PyEval_InitThreads ();

Upon reading the Python 3 C API documentation, I
found (https://docs.python.org/3.5/c-api/memory.html):

  To avoid memory corruption, extension writers should never try to
  operate on Python objects with the functions exported by the C
  library: malloc(), calloc(), realloc() and free(). This will result in
  mixed calls between the C allocator and the Python memory manager with
  fatal consequences, because they implement different algorithms and
  operate on different heaps. However, one may safely allocate and
  release memory blocks with the C library allocator for individual
  purposes[...]

And Py_SetProgramName seems like a very simple call that doesn't need
a Python-allocated memory to work on.  So I'm proposing this patch,
which simply replaces PyMem_Malloc by xmalloc.

Testing this is more complicated.  First, the crash is completely
non-deterministic; I was able to reproduce it 10 times in a row, and
then I wasn't able to reproduce it anymore.  I found that if you
completely remove your build directory and rebuild GDB from scratch,
you can reproduce it again confidently.  And with my patch, I
confirmed that the bug doesn't manifest even in this situation.

No regressions found.

OK to apply?

89549d7f4d Remove trailing newlines from help text
I noticed recently that some command had a trailing newline in its
"help" output.  So, I temporarily hacked cli-decode.c to print
something when a new command was installed that had a trailing newline
in its help message, and wrote this patch, which removes all the ones
I could find this way.  (There could still be a few more in *-nat
files.)

Tested on x86-64 Fedora 29.

422186a95c Remove newlines from warnings
ARI pointed out that a recent patch introduced a call to "warning"
with a string that ended in a newline:

    https://sourceware.org/ml/gdb-patches/2019-06/msg00000.html

This is generally forbidden, I believe, because warning adds its own
newline.

This patch removes all of the trailing newlines I was able to find.  I
searched for 'warning (.*\\n"' and then fixed the ones where the
newline appeared at the end of the string (some had internal
newlines).

Tested on x86-64 Fedora 29.

230d2906b9 Rename gdb exception types
This renames the gdb exception types.  The old types were only needed

b5eba2d8c0 Release the GIL while running a gdb command or expression
PR python/23615 points out that gdb.execute_gdb_command does not
release the Python GIL.  This means that, while the gdb command is
running, other Python threads do not run.

This patch solves the problem by introducing a new RAII class that can
be used to temporarily release and then re-acquire the GIL, then puts
this into the appropriate places in execute_gdb_command and
gdbpy_parse_and_eval.

This does not include a test case, because after some research I could
not find a way to write one that was not racy.

3fabc0163a Do not include py-ref.h in most files
py-ref.h can really only be included from a specific spot in
python-internal.h.  The other includes are not useful, and cause
compilation errors if the includes are ever sorted.  So, remove these
includes.

Arguably, py-ref.h should simply not be a separate header.
