+PyPy training session
+================================
+
+PyPy training session
+---------------------
+
+- Part 1: Run your application under PyPy
+
+- Part 2: Write your own interpreter with PyPy
+
+
+Part 1
+------
+
+* Run your application under PyPy
+
+
+How to run PyPy
+----------------
+
+* ``pypy program.py``
+
+* That's it!
+
+ - (modulo details)
+
+Challenge
+---------
+
+* ``html_fibo.py``
+
+* HTML list of fibonacci numbers
+
+* (the most complicate ever)
+
+* run it on CPython
+
+* run it on PyPy
+
+* fix it!
+
+
+Refcounting vs generational GC (1)
+----------------------------------
+
+|scriptsize|
+|example<| |scriptsize| ``gc0.py`` |end_scriptsize| |>|
+
+.. sourcecode:: python
+
+ def foo():
+ f = file('/tmp/bar.txt', 'w')
+ f.write('hello world')
+
+ foo()
+ print file('/tmp/bar.txt').read()
+
+|end_example|
+
+|pause|
+|example<| |scriptsize| ``gc1.py`` |end_scriptsize| |>|
+
+.. sourcecode:: python
+
+ def foo():
+ f = file('/tmp/bar.txt', 'w')
+ f.write('hello world')
+ f.close() # <-------
+
+|end_example|
+
+|pause|
+|example<| |scriptsize| ``gc2.py`` |end_scriptsize| |>|
+
+.. sourcecode:: python
+
+ def foo():
+ with file('/tmp/bar.txt', 'w') as f:
+ f.write('hello world')
+
+|end_example|
+|end_scriptsize|
+
+
+Refcounting vs generational GC (2)
+----------------------------------
+
+* ``__del__``
+
+ - especially files or sockets
+
+ - don't leak file descriptors!
+
+* weakrefs
+
+* ``finally`` inside generators
+
+
+
+Just-in-Time Compilation
+------------------------
+
+* Tracing JIT, like TraceMonkey
+
+* Complete by construction
+
+* Supports Intel x86, amd64, and soon ARM
+
+
+Short introduction to JITting
+-----------------------------
+
+* run code with the interpreter
+
+* observe what it does
+
+* generate optimized machine code for commonly executed paths
+
+* using runtime knowledge (types, paths taken)
+
+Tracing JIT
+-----------
+
+* compiles one loop at a time
+
+* generates linear code paths, recording what the interpreter did
+
+* for each possible branch, generate a guard, that exits assembler on triggering
+
+* if guard fails often enough, start tracing from the failure
+
+Meta-Tracing in PyPy
+--------------------
+
+* The explanation above assumes a tracing JIT for the full Python
+ language
+
+* Would need to be maintained whenever we change the Python version we
+ support
+
+* Instead, we have a "meta-tracing JIT"
+
+* A very important point for us since we don't have a huge team
+ to implement all Python semantics for the JIT
+
+* We trace the python interpreter's main loop (running N times) interpreting
+ a python loop (running once)
+
+
+PYPYLOG
+--------
+
+|small|
+
+* ``PYPYLOG=categories:logfile pypy program.py``
+
+|end_small|
+
+* categories:
+
+ - gc-minor, gc-major
+
+ - jit-log-noopt, jit-log-opt
+
+ - jit-backend
+
+ - jit-backend-counts
+
+
+Inspecting the JIT log
+-----------------------
+
+|scriptsize|
+|example<| |scriptsize| ``count.py`` |end_scriptsize| |>|
+
+.. sourcecode:: python
+
+ def count_mult_of_5(N):
+ mult = 0
+ not_mult = 0
+ for i in range(N):
+ if i % 5 == 0:
+ mult += 1
+ else:
+ not_mult += 1
+ return mult, not_mult
+
+|end_example|
+|end_scriptsize|
+
+|small|
+
+* ``PYPYLOG=jit-log-opt:mylog pypy count.py 2000``
+
+* ``PYPYLOG=jit-log-opt:mylog pypy count.py 10000``
+
+|end_small|
+
+
+The jitviewer
+-------------
+
+|scriptsize|
+
+* ``PYPYLOG=jit-log-opt,jit-backend-counts:mylog pypy count.py 2000``
+
+* ``PYPYLOG=jit-log-opt,jit-backend-counts:mylog pypy count.py 10000``
+
+* ``jitviewer.py log.pypylog``
+
+* Look at the (missing) bridge!
