Psyco -- the Python Specializing Compiler.
Typical usage: add the following lines to your application's main module:
\begin{description}
%[visit_definition_list_item]
\item[try::]
%[visit_definition]
import psyco
psyco.profile()
%[depart_definition]
%[depart_definition_list_item]
%[visit_definition_list_item]
\item[except::]
%[visit_definition]
print 'Psyco not found, ignoring it'
%[depart_definition]
%[depart_definition_list_item]
\end{description}

\hypertarget{functions}{}
\section*{Functions}
\pdfbookmark[0]{Functions}{functions}
\texttt{cannotcompile(x):}
\begin{quote}
Instruct Psyco never to compile the given function, method
or code object.
\end{quote}
\texttt{log(logfile='', mode='w', top=10):}
\begin{quote}
Enable logging to the given file.
If the file name is unspecified, a default name is built by appending
a 'log-psyco' extension to the main script name.
Mode is 'a' to append to a possibly existing file or 'w' to overwrite
an existing file. Note that the log file may grow quickly in 'a' mode.
\end{quote}
\texttt{runonly(memory=None, time=None, memorymax=None, timemax=None):}
\begin{quote}
Nonprofiler.
XXX check if this is useful and document.
\end{quote}
\texttt{profile(watermark = default{\_}watermark,}
\begin{quote}
Turn on profiling.
The 'watermark' parameter controls how easily running functions will
be compiled. The smaller the value, the more functions are compiled.
\end{quote}
\texttt{full(memory=None, time=None, memorymax=None, timemax=None):}
\begin{quote}
Compile as much as possible.
Typical use is for small scripts performing intensive computations
or string handling.
\end{quote}
\texttt{dumpcodebuf():}
\begin{quote}
Write in file psyco.dump a copy of the emitted machine code,
provided Psyco was compiled with a non-zero CODE{\_}DUMP.
See py-utils/httpxam.py to examine psyco.dump.
\end{quote}
\texttt{stop():}
\begin{quote}
Turn off all automatic compilation. bind() calls remain in effect.
\end{quote}
\texttt{proxy(x, rec=None):}
\begin{quote}
Return a Psyco-enabled copy of the function.
The original function is still available for non-compiled calls.
The optional second argument specifies the number of recursive
compilation levels: all functions called by func are compiled
up to the given depth of indirection.
\end{quote}
\texttt{background(watermark = default{\_}watermark,}
\begin{quote}
Turn on passive profiling.
This is a very lightweight mode in which only intensively computing
functions can be detected. The smaller the 'watermark', the more functions
are compiled.
\end{quote}
\texttt{unbind(x):}
\begin{quote}
Reverse of bind().
\end{quote}
\texttt{bind(x, rec=None):}
\begin{quote}
Enable compilation of the given function, method, or class object.
If C is a class (or anything with a '{\_}{\_}dict{\_}{\_}' attribute), bind(C) will
rebind all functions and methods found in C.{\_}{\_}dict{\_}{\_} (which means, for
classes, all methods defined in the class but not in its parents).
The optional second argument specifies the number of recursive
compilation levels: all functions called by func are compiled
up to the given depth of indirection.
\end{quote}
\texttt{{\_}getemulframe(depth=0):}
\begin{quote}
As {\_}getframe(), but the returned objects are real Python frame objects
emulating Psyco frames. Some of their attributes can be wrong or missing,
however.
\end{quote}
\texttt{unproxy(proxy):}
\begin{quote}
Return a new copy of the original function of method behind a proxy.
The result behaves like the original function in that calling it
does not trigger compilation nor execution of any compiled code.
\end{quote}
