396a78b627 Use gdbpy_enter in python_interactive_command
This changes python_interactive_command to use gdbpy_enter.
Previously this function was leaving a dangling cleanup -- this is
sort of ok in a command function, but IMO it's still better to clean
up.

6349f452e0 Introduce htab_up and use gdbpy_enter in py-framefilter.c
This introduces a new "htab_up" typedef, which is a std::unique_ptr
that can call htab_delete.  Then it changes some code in
py-framefilter.c to use both gdbpy_enter and the new htab_up.

abf5651e47 Change event code to use gdbpy_ref
This changes the event code in the Python layer to use
gdbpy_ref, simplifying the logic in many places.

It also changes evpy_emit_event not to steal a reference to its
argument.  This is simpler to do now that gdbpy_ref is in use;
it's also a reasonable cleanup in its own right.  While doing this I
realized that evpy_emit_event should not be calling gdbpy_print_stack
(all the outermost callers do this if needed), so I removed this as
well.

a68ff33e0d Introduce py-ref.h
This patch introduces class gdbpy_ref, which is a sort of smart
pointer that owns a single Python reference to a PyObject.  This class
acts a bit like unique_ptr, but also a bit like shared_ptr (in that
copies do what you might expect); I considered going solely with
unique_ptr but it seemed quite strange to have a unique_ptr that
actually manages a shared resource.

Subsequent patches use this new class to simplify logic in the Python
layer.

2017-01-10  Tom Tromey  <tom@tromey.com>

112e8700a6 Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy.  ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.

In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.

It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

3fff9862d5 Create subobject value in pretty printer
Nowadays, we create a value of subobject in pretty printer with 'address'
being used,

  value = value_from_contents_and_address (type, valaddr + embedded_offset,
					   address + embedded_offset);

  set_value_component_location (value, val);
  /* set_value_component_location resets the address, so we may
     need to set it again.  */
  if (VALUE_LVAL (value) != lval_internalvar
      && VALUE_LVAL (value) != lval_internalvar_component
      && VALUE_LVAL (value) != lval_computed)
    set_value_address (value, address + embedded_offset);

value_from_contents_and_address creates a value from memory, but the
value we are pretty-printing may not from memory at all.

Instead of using value_from_contents_and_address, we create a value
of subobject with the same location as object's but different offset.
We avoid using address in this way.  As a result, parameter 'address'
in apply_val_pretty_printer is no longer needed, we can remove it in
next step.

We've already had the location of the 'whole' value, so it is safe
to assume we can create a value of 'component' or 'suboject' value
at the same location but with different offset.

33cc7d368f Make gdb.PendingFrame.read_register handle "user" registers.
The C function, pending_framepy_read_register(), which implements
the python interface gdb.PendingFrame.read_register does not handle
the so called "user" registers like "pc".  An assertion error is
triggered due to the user registers having numbers larger than or
equal to gdbarch_num_regs(gdbarch).

With the VALUE_FRAME_ID tweak in place, the call to
get_frame_register_value() can simply be replaced by a call to
value_of_register(), which handles both real registers as well as the
user registers.

	* python/py-unwind.c (pending_framepy_read_register): Use
	value_of_register() instead of get_frame_register_value().

9b9720149d Use unique_xmalloc_ptr in Python code
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.

30a7bb833c Fix some error-handling bugs in python frame filters
While writing a Python frame filter, I found a few bugs in the current
frame filter code.  In particular:

* One spot converts a Python long to a CORE_ADDR using PyLong_AsLong.
  However, this can fail on overflow.  I changed this to use
  get_addr_from_python.

* Another spot is doing the same but with PyLong_AsUnsignedLongLong; I
  changed this as well just for consistency.

* Converting line numbers can print "-1" if conversion from long
  fails.  This isn't fatal but just a bit ugly.

I've included a test case for the first issue.  The line number one
didn't seem important enough to bother with.

2016-11-08  Tom Tromey  <tom@tromey.com>

	* python/py-framefilter.c (py_print_frame): Use
	get_addr_from_python.  Check for errors when getting line number.

2f408ecb92 Use ui_file_as_string throughout more
This replaces most of the remaining ui_file_xstrdup calls with
ui_file_as_string calls.  Whenever a call was replaced, that led to a
cascade of other necessary adjustments throughout, to make the code
use std::string instead of raw pointers.  And then whenever I added a
std::string as member of a struct, I needed to adjust
allocation/destruction of said struct to use new/delete instead of
xmalloc/xfree.

The stopping point was once gdb built again.  These doesn't seem to be
a way to reasonably split this out further.

Maybe-not-obvious changes:

 - demangle_for_lookup returns a cleanup today.  To get rid of that,
   and avoid unnecessary string dupping/copying, this introduces a
   demangle_result_storage type that the caller instantiates and
   passes to demangle_for_lookup.

 - Many methods returned a "char *" to indicate that the caller owns
   the memory and must free it.  Those are switched to return a
   std::string instead.  Methods that return a "view" into some
   internal string return a "const char *" instead.  I.e., we only
   copy/allocate when necessary.

b15cc25cbe Make symfile_add_flags and objfile->flags strongly typed
This makes these flag types be "enum flag" types.  The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.

This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:

  @@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)
	what is frameless.  */
     reinit_frame_cache ();

  -  if ((flags & SYMFILE_NO_READ) == 0)
  +  if ((add_flags & SYMFILE_NO_READ) == 0)
       set_initial_language ();
   }

Above, "flags" are objfile flags, not symfile_add_flags.  So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...

I moved the flags definitions to separate files to break circular
dependencies.

Built with --enable-targets=all and tested on x86-64 Fedora 23.

b7b633e9b1 Use RAII to save and restore scalars
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.

12c58cd4dc Avoid -Wduplicated-cond warnings in gdb/python
I tried building gdb with -Wduplicated-cond.  This patch fixes the
simpler issue that was found.

In Python 3, "int" and "long" are synonyms, so code like:

      else if (PyLong_Check (obj))
...
      else if (PyInt_Check (obj))

.... will trigger this warning.  The fix is to conditionalize the
PyInt_Check branches on Python 2.

Tested by rebuilding, with both version of Python, on x86-64 Fedora 24.
