This is Guppy-PE version 0.1.10
A Python Programming Environment.
CONTENTS
This distribution provides a root package, guppy, with the following
subpackages:
doc Documentation data files: *.html, *.jpg, and help support.
etc Support modules. Contains especially the Glue protocol module.
gsl The Guppy Specification Language implementation. This can
be used to create documents and tests from a common source.
heapy The heap analysis toolset. It can be used to find information
about the objects in the heap and display the information
in various ways.
sets Bitsets and 'nodesets' implemented in C.
The following files are not in packages but on the toplevel:
gsl-mode-0.1.el Emacs mode for GSL
specs/*.gsl Specifications
specs/genguppydoc.py Regenerates the doc/*.html files from specs/*.gsl
REQUIREMENTS
You should have Python 2.3, 2.4, 2.5 or 2.6
To build the system so you can use Heapy, you should have what is
needed to build extension modules from source code. The extension
modules are used not only in Heapy but also in GSL in some
situations. (The test generator uses bitsets to speed up an
algorithm.)
To use the graphical browser, Tkinter is needed.
To use the remote monitor, threading must be available.
INSTALLATION
Extract the files from the .tar.gz file, in Linux for example by:
tar xzf guppy-x.y.z.tar.gz
where x.y.z is the current version number. This will create the
directory guppy-x.y.z . You should then cd into this directory. You
can then compile the extension modules by:
python setup.py build
And to install you can do, for example, as follows to install to the
default location (when you are super-user):
python setup.py install
NOTE that you typically must LEAVE the guppy-x.y.z directory to use
Heapy, since the current directory is usually in the Python search
path, and then Python will find the guppy directory there FIRST and
will NOT find the extension modules. This may be a somewhat common
problem -- so I am noting it here for lack of a suitable fix at the
moment.
I also note that the documentation files and emacs-mode are not
automatically installed.
HEAPY USAGE EXAMPLE
The following example shows
1. How to create the session context: h=hpy()
2. How to show the reachable objects in the heap: h.heap()
3. How to create and show a set of objects: h.iso(1,[],{})
4. How to show the shortest paths from the root to x: h.iso(x).sp
>>> from guppy import hpy; h=hpy()
>>> h.heap()
Partition of a set of 48477 objects. Total size = 3265516 bytes.

TEST
To test if the heapy build and installation was ok, you can do:
>>> from guppy import hpy
>>> hpy().test()
Testing sets
Test #0
Test #1
Test #2
...
There will be several more tests. Some tests may take a while.
Caveat 1: Some tests may be somewhat picky, and may have to be relaxed
to pass in different installations.
Caveat 2: All tests don't currently work always in Python 2.7
