This is Guppy-PE version 0.1.9 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.

There will be several more tests. Some tests may take a while. Caveat: Some tests may be somewhat picky, and may have to be relaxed to pass in different installations.
