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 removes some unused variables, found with -Wunused. I have
not removed everything reported by -Wunused, because some expressions
such as
struct type *arg_type = check_typedef (value_type);
in bfin-tdep.c could have an unexpected but important side-effect. I
removed others that I considered more low-risk, such as:
struct gdbarch *gdbarch = get_objfile_arch (objfile);
I tested building with Python 2/Python 3/no Python, with/without expat,
with/without libipt and with/without babeltrace.

This patch teaches GDB about setting breakpoints in all scopes
(namespaces and classes) by default.
Here's a contrived example:
(gdb) b func<tab>
(anonymous namespace)::A::function() Bn::(anonymous namespace)::B::function() function(int, int)
(anonymous namespace)::B::function() Bn::(anonymous namespace)::function() gdb::(anonymous namespace)::A::function()
(anonymous namespace)::B::function() const Bn::(anonymous namespace)::function(int, int) gdb::(anonymous namespace)::function()
(anonymous namespace)::function() Bn::B::func() gdb::(anonymous namespace)::function(int, int)
(anonymous namespace)::function(int, int) Bn::B::function() gdb::A::func()
A::func() Bn::func() gdb::A::function()
A::function() Bn::function() gdb::func()
B::func() Bn::function(int, int) gdb::function()
B::function() Bn::function(long) gdb::function(int, int)
B::function() const func() gdb::function(long)
B::function_const() const function()
(gdb) b function
Breakpoint 1 at 0x4005ce: function. (26 locations)
(gdb) b B::function<tab>
(anonymous namespace)::B::function() B::function() const Bn::B::function()
(anonymous namespace)::B::function() const B::function_const() const
B::function() Bn::(anonymous namespace)::B::function()
(gdb) b B::function
Breakpoint 1 at 0x40072c: B::function. (6 locations)
To get back the original behavior of interpreting the function name as
a fully-qualified name, you can use the new "-qualified" (or "-q")
option/flag (added by this commit). For example:
(gdb) b B::function
(anonymous namespace)::B::function() B::function() const Bn::B::function()
(anonymous namespace)::B::function() const B::function_const() const
B::function() Bn::(anonymous namespace)::B::function()
vs:
(gdb) b -qualified B::function
B::function() B::function() const B::function_const() const
I've chosen "-qualified" / "-q" because "-f" (for "full" or
"fully-qualified") is already taken for "-function".
Note: the "-qualified" option works with both linespecs and explicit
locations. I.e., these are equivalent:
(gdb) b -q func
(gdb) b -q -f func
and so are these:
(gdb) b -q filename.cc:func
(gdb) b -q -s filename.cc -f func
(gdb) b -s filename.cc -q -f func
(gdb) b -s filename.cc -f func -q
To better understand why I consider wild matching the better default,
consider what happens when we get to the point when _all_ of GDB is
wrapped under "namespace gdb {}". I have a patch series that does
that, and when I started debugging that GDB, I immediately became
frustrated. You'd have to write "b gdb::internal_error", "b
gdb::foo", "b gdb::bar", etc. etc., which gets annoying pretty
quickly. OTOH, consider how this makes it very easy to set
breakpoints in classes wrapped in anonymous namespaces. You just
don't think of them, GDB finds the symbols for you automatically.
(At the Cauldron a couple months ago, several people told me that they
run into a similar issue when debugging other C++ projects. One
example was when debugging LLVM, which puts all its code under the
"llvm" namespace.)
Implementation-wise, what the patch does is:
- makes C++ symbol name hashing only consider the last component of
a symbol name. (so that we can look up symbol names by
last-component name only).
- adds a C++ symbol name matcher for symbol_name_match_type::WILD,
which ignores missing leading specifiers / components.
- adjusts a few preexisting testsuite tests to use "-qualified" when
they mean it.
- adds new testsuite tests.
- adds unit tests.
Grows the gdb.linespec/ tests like this:
-# of expected passes 7823
+# of expected passes 8977

While playing with valgrind, I noticed that with Python 3, the progname
variable in do_start_initialization is not being freed (concat returns a
malloc'ed string). This patch uses unique_xmalloc_ptr to manage it.
With Python 2, we pass progname it directly to Py_SetProgramName, so it
should not be freed. We therefore release it before passing it.
gdb/ChangeLog:
* python/python.c (do_start_initialization): Change progname
type to gdb::unique_xmalloc_ptr. Release the pointer when using
Python 2.

This changes add_com to take a cmd_const_cfunc_ftype, and then fixes
up all the command implementations.
In most cases this is trivial.
In a couple of places I had to again introduce a temporary non-const
overload. These overloads will be removed when add_info is
constified.

This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.
In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors". These overloads are temporary; once constification is
complete they can be removed.
This patch also fixes a typo I happened to notice while constifying.
Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build. So, while I made a best-effort there, I am not
certain they will still compile.
Tested by rebuilding.

The first patch in this series went through several iterations as I'd
forgotten how many places had to be touched to add a new event and a
new event type.
This patch simplifies the process using two new ".def" files. Now, a
new event type can be added by adding a line to "py-event-types.def",
and a new event registry can be added by adding a line to
"py-all-events.def".

This adds a few new events to gdb's Python layer: new_inferior,
inferior_deleted, and new_thread. I wanted to be able to add a
combined inferior/thread display window to my GUI, and I needed a few
events to make this work. This is PR python/15622.

This replaces "struct symtabs_and_lines" with
std::vector<symtab_and_line> in most cases. This removes a number of
cleanups.
In some cases, the sals objects do not own the sals they point at.
Instead they point at some sal that lives on the stack. Typically
something like this:
struct symtab_and_line sal;
struct symtabs_and_lines sals;
// fill in sal
sals.nelts = 1;
sals.sals = &sal;
// use sals
Instead of switching those cases to std::vector too, such usages are
replaced by gdb::array_view<symtab_and_line> instead. This avoids
introducing heap allocations.

This removes cleanups from gdbpy_decode_line, in favor of a use of
unique_xmalloc_ptr.

This adds a generic instruction class to Python and has gdb.RecordInstruction
inherit from it.
|

This introduces command_line_up, a unique_ptr for command_line
objects, and changes many places to use it. This removes a number of
cleanups.
Command lines are funny in that sometimes they are reference counted.
Once there is more C++-ification of some of the users, perhaps all of
these can be changed to use shared_ptr instead.

This removes make_cleanup_delete_event_location and instead changes
the various location functions to return an event_location_up, a new
unique_ptr typedef.
This is largely straightforward, but be sure to examine the
init_breakpoint_sal change. I believe the code I deleted there is
dead, because "location != NULL" can never be true in that branch; but
you should double-check.

GDB fails to build for Windows host with Python 2 support enabled due
to PyFile_FromString's second argument being of type char * and being
passed a (const) string literal. This parameter is input only so this
commit fixes the issue by casting to char *.

* python/python.c (python_run_simple_file): Cast mode literal to
non-const char pointer as expected by PyFile_FromString.

-Wwrite-strings flags code like:
static char *keywords[] = {"command", "from_tty", "to_string", NULL };
as needing "(char *)" casts, because string literals are "const char []".
We can get rid of the casts by changing the array type like this:
- static char *keywords[] = {"command", "from_tty", "to_string", NULL };
+ static const char *keywords[] = {"command", "from_tty", "to_string", NULL };
However, passing the such array to PyArg_ParseTupleAndKeywords no longer
works OOTB, because PyArg_ParseTupleAndKeywords expects a "char **":
PyArg_ParseTupleAndKeywords(PyObject *args, PyObject *kw,
const char *format,
char *keywords[], ...);
and "const char **" is not implicitly convertible to "char **". C++
is more tolerant that C here WRT aliasing, and a const_cast<char **>
is fine. However, to avoid having all callers do the cast themselves,
this commit defines a gdb_PyArg_ParseTupleAndKeywords function here
with a corresponding 'keywords' parameter type that does the cast in a
single place.

2017-04-05 Pedro Alves <palves@redhat.com>
* python/python-internal.h (gdb_PyArg_ParseTupleAndKeywords): New

The patch "Fix memory leak in python.c:do_start_initialization"
(https://sourceware.org/ml/gdb-patches/2017-03/msg00407.html) introduced a
compilation error on some platforms:
../../binutils-gdb/gdb/python/python.c: In function bool do_start_initialization():
../../binutils-gdb/gdb/python/python.c:1556:16: error: invalid conversion from const void* to void* [-fpermissive]
xfree (libdir);
^
This is fixed by removing the constness of libdir's data type.
gdb/ChangeLog:
* python/python.c (do_start_initialization): Remove 'const' from
data type of libdir.
|
|
When intializing Python the path to the python binary is build the
following way
progname = concat (ldirname (python_libdir), SLASH_STRING, "bin",
SLASH_STRING, "python", (char *) NULL);
This is problematic as both concat and ldirname allocate memory for the
string they return. Thus the memory allocated by ldirname cannot be
accessed afterwards causing a memory leak. Fix it by temporarily storing
libdir in a variable and xfree it after concat.
gdb/ChangeLog:
python/python.c (do_start_initialization): Fix memory leak.

This adds an event that is emitted just before GDB presents a prompt
to the user. This provides Python code a way to react to whatever
changes might have been made by the previous command. For example, in
my GUI I use this to track changes to the selected frame and reflect
them in the UI.
Built and regtested on x86-64 Fedora 23.

This changes the last functions in python.c to use gdbpy_enter. I

This changes python_interactive_command to use gdbpy_enter.
Previously this function was leaving a dangling cleanup -- this is

This changes some utility functions in the Python code to return
unique_xmalloc_ptr, and then fixes up the callers.
I chose unique_xmalloc_ptr rather than std::string because at a few
call points the xmalloc'd string is released and ownership transferred
elsewhere.
This patch found a few existing memory leaks. For example,
py-unwind.c called gdbpy_obj_to_string but never freed the result.
Built and regression tested on the buildbot.

This patch replaces many (but not all) uses of
make_cleanup_restore_integer with a simple RAII-based template class.
It also removes the similar restore_execution_direction cleanup in
favor of this new class. Subsequent patches will replace other
similar cleanups with this class.
The class is typically instantiated using make_scoped_restore. This
allows for template argument deduction.

The gdb.decode_line python function is documented to support the same location
expressions as the "break" command. It currently expects a linespec location.
Instead of creating a linespec location directly, create the location via

PR python/19293 notes that when a Python unwinder is disabled, the
frame cache is not invalidated. This means that disabling an unwinder
doesn't have any immediate effect -- but in my experience it's often
the case that I want to enable or disable an unwinder in order to see
what happens.
This patch adds a new gdb.invalidate_cached_frames function and
arranges for the relevant bits of library code to call it. I've only
partially documented this function, considering a warning sufficient
without going into all the reasons ordinary code should not call it.
The name of the new function was taken from a comment in frame.h next
to reinit_frame_cache.
No new test as I think the updates to the existing test are sufficient
to show that the code is working as intended.
Built and regtested on x86-64 Fedora 23.
