Ivan Smirnov 5e71e17bdf Make changes to format_descriptor backwards-compat 
The format strings that are known at compile time are now accessible
via both ::value and ::format(), and format strings for everything
else is accessible via ::format(). This makes it backwards compatible.

Wenzel Jakob 09f40e010f Merge pull request #282 from jagerman/key-iterators 
Add pybind11::make_key_iterator for map iteration
 2016-08-12 08:35:45 +02:00
Jason Rhinelander 5aa85be26e Added pybind11::make_key_iterator for map iteration 
This allows exposing a dict-like interface to python code, allowing
iteration over keys via:

    for k in custommapping:
        ...

while still allowing iteration over pairs, so that you can also
implement 'dict.items()' functionality which returns a pair iterator,
allowing:

    for k, v in custommapping.items():
        ...

example-sequences-and-iterators is updated with a custom class providing
both types of iteration.

Improve constructor/destructor tracking
 2016-08-12 00:56:26 +02:00
Jason Rhinelander 3f589379ec Improve constructor/destructor tracking 
This commit rewrites the examples that look for constructor/destructor
calls to do so via static variable tracking rather than output parsing.

The added ConstructorStats class provides methods to keep track of
constructors and destructors, number of default/copy/move constructors,
and number of copy/move assignments.  It also provides a mechanism for
storing values (e.g. for value construction), and then allows all of
this to be checked at the end of a test by getting the statistics for a
C++ (or python mapping) class.

By not relying on the precise pattern of constructions/destructions,
but rather simply ensuring that every construction is matched with a
destruction on the same object, we ensure that everything that gets
created also gets destroyed as expected.

This replaces all of the various "std::cout << whatever" code in
constructors/destructors with
`print_created(this)`/`print_destroyed(this)`/etc. functions which
provide similar output, but now has a unified format across the
different examples, including a new ### prefix that makes mixed example
output and lifecycle events easier to distinguish.

With this change, relaxed mode is no longer needed, which enables
testing for proper destruction under MSVC, and under any other compiler
that generates code calling extra constructors, or optimizes away any
constructors.  GCC/clang are used as the baseline for move
constructors; the tests are adapted to allow more move constructors to
be evoked (but other types are constructors much have matching counts).

This commit also disables output buffering of tests, as the buffering
sometimes results in C++ output ending up in the middle of python
output (or vice versa), depending on the OS/python version.

Silence MSVC warning
 2016-08-11 22:35:15 +02:00
Jason Rhinelander e20fc61a33 Silence MSVC warning 
PR #329 generates the following warning under MSVC:

    ...\cast.h(202): warning C4456: declaration of 'it' hides previous local declaration

This renames the second iterator to silence it.

Wenzel Jakob 5a4cd3b45c Merge pull request #329 from jagerman/track-same-ptr-instances 
Track registered instances that share a pointer address
 2016-08-10 18:24:10 +02:00
Jason Rhinelander f2ecd8927e Implement reference_internal with a keep_alive 
reference_internal requires an `instance` field to track the returned
reference's parent, but that's just a duplication of what
keep_alive<0,1> does, so use a keep alive to do this to eliminate the
duplication.
 2016-08-10 12:08:04 -04:00
Jason Rhinelander efc2aa7ee7 Removed obsolete documentation about duplicate address problems 
It no longer applies since instances are now identified by both address
and type.
