Currently, when we add a new python sub-system to GDB,
e.g. py-inferior.c, we end up having to create a new function like
gdbpy_initialize_inferior, which then has to be called from the
function do_start_initialization in python.c.
In some cases (py-micmd.c and py-tui.c), we have two functions
gdbpy_initialize_*, and gdbpy_finalize_*, with the second being called
from finalize_python which is also in python.c.
This commit proposes a mechanism to manage these initialization and
finalization calls, this means that adding a new Python subsystem will
no longer require changes to python.c or python-internal.h, instead,
the initialization and finalization functions will be registered
directly from the sub-system file, e.g. py-inferior.c, or py-micmd.c.
The initialization and finalization functions are managed through a
new class gdbpy_initialize_file in python-internal.h. This class
contains a single global vector of all the initialization and
finalization functions.
In each Python sub-system we create a new gdbpy_initialize_file
object, the object constructor takes care of registering the two
callback functions.
Now from python.c we can call static functions on the
gdbpy_initialize_file class which take care of walking the callback
list and invoking each callback in turn.
To slightly simplify the Python sub-system files I added a new macro
GDBPY_INITIALIZE_FILE, which hides the need to create an object. We
can now just do this:
GDBPY_INITIALIZE_FILE (gdbpy_initialize_registers);
One possible problem with this change is that there is now no
guaranteed ordering of how the various sub-systems are initialized (or
finalized). To try and avoid dependencies creeping in I have added a
use of the environment variable GDB_REVERSE_INIT_FUNCTIONS, this is
the same environment variable used in the generated init.c file.
Just like with init.c, when this environment variable is set we
reverse the list of Python initialization (and finalization)
functions. As there is already a test that starts GDB with the
environment variable set then this should offer some level of
protection against dependencies creeping in - though for full
protection I guess we'd need to run all gdb.python/*.exp tests with
the variable set.
I have tested this patch with the environment variable set, and saw no
regressions, so I think we are fine right now.
One other change of note was for gdbpy_initialize_gdb_readline, this
function previously returned void. In order to make this function
have the correct signature I've updated its return type to int, and we
now return 0 to indicate success.
All of the other initialize (and finalize) functions have been made
static within their respective sub-system files.
There should be no user visible changes after this commit.

Hannes filed a bug showing a crash, where a pretty-printer written in
Python could cause a use-after-free. He sent a patch, but I thought a
different approach was needed.
In a much earlier patch (see bug #12533), we changed the Python code
to release new values from the value chain when constructing a
gdb.Value. The rationale for this is that if you write a command that
does a lot of computations in a loop, all the values will be kept live
by the value chain, resulting in gdb using a large amount of memory.
However, suppose a value is passed to Python from some code in gdb
that needs to use the value after the call into Python. In this
scenario, value_to_value_object will still release the value -- and
because gdb code doesn't generally keep strong references to values (a
consequence of the ancient decision to use the value chain to avoid
memory management), this will result in a use-after-free.
This scenario can happen, as it turns out, when a value is passed to
Python for pretty-printing. Now, normally this route boxes the value
via value_to_value_object_no_release, avoiding the problematic release
from the value chain. However, if you then call Value.cast, the
underlying value API might return the same value, when is then
released from the chain.
This patch fixes the problem by changing how value boxing is done.
value_to_value_object no longer removes a value from the chain.
Instead, every spot in gdb that might construct new values uses a
scoped_value_mark to ensure that the requirements of bug #12533 are
met. And, because incoming values aren't ever released from the chain
(the Value.cast one comes earlier on the chain than the
scoped_value_mark), the bug can no longer occur. (Note that many
spots in the Python layer already take this approach, so not many
places needed to be touched.)
In the future I think we should replace the use of raw "value *" with
value_ref_ptr pretty much everywhere. This will ensure lifetime
safety throughout gdb.
The test case in this patch comes from Hannes' original patch. I only
made a trivial ("require") change to it. However, while this fails
for him, I can't make it fail on this machine; nevertheless, he tried
my patch and reported the bug as being fixed.

New in this version:
- Rebase on master, fix a few more issues that appeared.
python-internal.h contains a number of macros that helped make the code
work with both Python 2 and 3. Remove them and adjust the code to use
the Python 3 functions.

Currently, gdb's Python layer captures the current architecture and
language when "entering" Python code. This has some undesirable
effects, and so this series changes how this is handled.
First, there is code like this:
gdbpy_enter enter_py (python_gdbarch, python_language);
This is incorrect, because both of these are NULL when not otherwise
assigned. This can cause crashes in some cases -- I've added one to
the test suite. (Note that this crasher is just an example, other
ones along the same lines are possible.)
Second, when the language is captured in this way, it means that
Python code cannot affect the current language for its own purposes.
It's reasonable to want to write code like this:
gdb.execute('set language mumble')
... stuff using the current language
gdb.execute('set language previous-value')
However, this won't actually work, because the language is captured on
entry. I've added a test to show this as well.
This patch changes gdb to try to avoid capturing the current values.
The Python concept of the current gdbarch is only set in those few
cases where a non-default value is computed or needed; and the
language is not captured at all -- instead, in the cases where it's
required, the current language is temporarily changed.

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).

directly. This is quite a big diff, but this was mostly done using sed
and coccinelle. A few call sites were done by hand.
gdb/ChangeLog:
* gdbtypes.h (TYPE_CODE): Remove. Change all call sites to use
type::code instead.

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.

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.

This replaces more pointer+length with gdb::array_view. This time,
around invoke_xmethod, and then propagating the fallout around, which
inevitably leaks to the overload resolution code.
There are several places in the code that want to grab a slice of an
array, by advancing the array pointer, and decreasing the length
pointer. This patch introduces a pair of new
gdb::array_view::slice(...) methods to make that convenient and clear.
Unit test included.

I think that the clone method of xmethod_worker can be removed. It is
only used in find_overload_match, to clone an xmethod we want to
keep. Instead, we can just std::move it out of the vector and into
value_from_xmethod. value_from_xmethod creates a value that will own
the xmethod_worker from that point. Other xmethod_workers left in the
vector will get destroyed when the vector gets destroyed, but the chosen
one will keep living inside the value struct.
gdb/ChangeLog:
* extension.h (struct xmethod_worker) <clone>: Remove.
* python/py-xmethods.c (struct python_xmethod_worker) <clone>:
Remove.
(python_xmethod_worker::clone): Remove.
* valops.c (find_overload_match): Use std::move instead of

The initial goal of this patch was to remove the usage of
VEC(xmethod_worker_ptr) and corresponding cleanups. I ended up having
to C++ify the xmethod_worker code, to be able to have xmethod_workers
free their data in destructors, and therefore be able to use vectors of
xmethod_worker unique_ptr.
The operations in extension_language_ops that act on one instance of
xmethod_worker (get result type, get args type, invoke) are transformed
to methods of xmethod_worker. xmethod_worker becomes an abstract base
class with virtual pure methods which python_xmethod_worker implements.
The only xmethod-related operation left in extension_language_ops is
get_matching_xmethod_workers, which returns a list of xmethod_workers.
The changes are relatively straightforward, but here are some notes on
things that may raise eyebrows:
- I was not really comfortable with the value_of_xmethod function. At
first it looks like a simple getter, so I considered making it a
method of xmethod_worker. But actually it creates a value and
transfers the ownership of the xmethod_worker to it. It would be a
bit weird and error-prone if calling a method on an object silently
removed the ownership of the object from the caller. To reflect the
behavior more accurately, I renamed it to value_from_xmethod and made
it accept an rvalue-reference (so the caller knows it gives away the
ownership). I noticed the backlink from xmethod_worker to its owning
value was not used, so I removed it.
- Some code, like get_matching_xmethod_workers, made each callee fill
a new vector, which was then merged in the result vector. I think
it's safe if we always pass the same vector around, and each
implementation just appends to it.
- The clone operation does not seem particularly useful, it is removed
in the following patch.

This patch adds the ability to inspect rvalue reference types and values using
the gdb python module. This is achieved by creating two wrappers for
valpy_reference_value(), using the ReferenceExplorer class to handle the
objects of rvalue reference types and placing necessary checks for a
TYPE_CODE_RVALUE_REF type code next to the checks for a TYPE_CODE_REF type
code.

wrap subclasses of PyObject. The default argument remains PyObject;
and this necessitated renaming uses of "gdbpy_ref" to "gdbpy_ref<>".

* python/py-ref.h (gdbpy_ref_policy): Now a template.

When the gdbpy_ref objects get destroyed, they call Py_DECREF to
decrement the reference counter of the python object they hold a
reference to. Any time we call into the Python API, we should be
holding the GIL. The gdbpy_enter object does that for us in an
RAII-fashion.
However, if gdbpy_enter is declared after a gdbpy_ref object in a
function, gdbpy_enter's destructor will be called (and the GIL will be
released) before gdbpy_ref's destructor is called. Therefore, we will
end up calling Py_DECREF without holding the GIL.
This became obvious with Python 3.6, where memory management functions
have asserts to make sure that the GIL is held. This was exposed by
tests py-as-string.exp, py-function.exp and py-xmethods. For example:
(gdb) p $_as_string(enum_valid)

The fix is to place the gdbpy_enter first in the function. I also
cleaned up the comments a bit and removed the unnecessary initialization
of the value variable.

the gdbpy_enter object declared first.
