+Hello everyone!
+
+We've wrapped up the Warsaw sprint, so I would like to describe some
+branches which have been recently merged and which improved the I/O and the
+GC: `gc_no_cleanup_nursery`_ and `gc-incminimark-pinning`_.
+
+.. _`gc_no_cleanup_nursery`: 
https://bitbucket.org/pypy/pypy/commits/9e2f7a37c1e2
+.. _`gc-incminimark-pinning`: 
https://bitbucket.org/pypy/pypy/commits/64017d818038
+
+The first branch was started by Wenzhu Man for her Google Summer of Code
+and finished by Maciej Fijałkowski and Armin Rigo.
+The PyPy GC works by allocating new objects in the young object
+area (the nursery), simply by incrementing a pointer. After each minor
+collection, the nursery has to be cleaned up. For simplicity, the GC used 
+to do it by zeroing the whole nursery.
+
+This approach has bad effects on the cache, since you zero a large piece of
+memory at once and do unnecessary work for things that don't require zeroing
+like large strings. We mitigated the first problem somewhat with incremental
+nursery zeroing, but this branch removes the zeroing completely, thus
+improving the string handling and recursive code (since jitframes don't
+requires zeroed memory either). I measured the effect on two examples: 
+a recursive implementation of  `fibonacci`_ and `gcbench`_,
+to measure GC performance.
+
+.. _`fibonacci`: 
https://bitbucket.org/pypy/benchmarks/src/69152c2aee7766051aab15735b0b82a46b82b802/own/fib.py?at=default
+.. _`gcbench`: 
https://bitbucket.org/pypy/benchmarks/src/69152c2aee7766051aab15735b0b82a46b82b802/own/gcbench.py?at=default
+
+The results for fibonacci and gcbench are below (normalized to cpython
+2.7). Benchmarks were run 50 times each (note that the big standard
+deviation comes mostly from the warmup at the beginning, true figures
+are smaller):
+
+++- 
+-++
+| benchmark  | CPython  | PyPy 2.4| PyPy non-zero

+| fibonacci  | 4.8+-0.15 (1.0x) | 0.59+-0.07 (8.1x)   | 0.45+-0.07

+++--+-++
+
+The second branch was done by Gregor Wegberg for his master thesis and finished
+by Maciej Fijałkowski and Armin Rigo. Because of the way it works, the 
PyPy GC from
+time to time moves the objects in memory, meaning that their address can 
change.
+Therefore, if you want to pass pointers to some external C function (for
+example, write(2) or read(2)), you need to ensure that the objects they are
+pointing to will not be moved by the GC (e.g. when running a different thread).
+PyPy up to 2.4 solves the problem by copying the data into or from a 
non-movable buffer, which
+is obviously inefficient.
+The branch introduce the concept of "pinning", which allows us to inform the
+GC that it is not allowed to move a certain object for a short period of time.
+This introduces a bit of extra complexity
+in the garbage collector, but improves the I/O performance quite drastically,
+because we no longer need the extra copy to and from the non-movable buffers.
+
+In `this benchmark`_, which does I/O in a loop,
+we either write a number of bytes from a freshly allocated string into
+/dev/null or read a number of bytes from /dev/full. I'm showing the results
+for PyPy 2.4, PyPy with non-zero-nursery and PyPy with non-zero-nursery and
+object pinning. Those are wall times for cases using ``os.read/os.write``
+and ``file.read/file.write``, normalized against CPython 2.7.
+
+Benchmarks were done using PyPy 2.4 and revisions ``85646d1d07fb`` for
+non-zero-nursery and ``3d8fe96dc4d9`` for non-zero-nursery and pinning.
+The benchmarks were run once, since the standard deviation was small.
+
+
+
+What we can see is that ``os.read`` and ``os.write`` both improved greatly
+and outperforms CPython now for each combination. ``file`` operations are
+a little more tricky, and while those branches improved the situation a bit,
+the improvement is not as drastic as in ``os`` versions.  It really should not
+be the case and it showcases how our ``file`` buffering is inferior to CPython.
+We plan on removing our own buffering and using ``FILE*`` in C in the near 
future,
+so we should outperform CPython on those too (since our allocations are 
cheaper).
+If you look carefully in the benchmark, the write function is copied three 
times

[pypy-commit] pypy jit-targets: Rename ProcedureToken to JitCellToken. It now refers to all compiled traces starting from a specific JitCell and it is used as a decsr of jumps produced by the frontend

Log:Rename ProcedureToken to JitCellToken. It now refers to all compiled
traces starting from a specific JitCell and it is used as a decsr of
jumps produced by the frontend to indicate the target of the jump.
The optimizer will the convert this to a jump to a TargetToken
(which refers to a specific label in an already compiled trace). If
that is not yet possible it will be converted into a label resop
with a new TargetTocken
