Modular toolkit for Data Processing 2.4 released!
by Tiziano Zito Oct. 22, 2008

Oct. 22, 2008

We are glad to announce release 2.4 of the Modular toolkit for Data Processing (MDP). MDP is a Python library of widely used data processing algorithms that can be combined according to a pipeline analogy to build more complex data processing software. The base of available algorithms includes, to name but the most common, Principal Component Analysis (PCA and NIPALS), several Independent Component Analysis algorithms (CuBICA, FastICA, TDSEP, and JADE), Slow Feature Analysis, Restricted Boltzmann Machine, and Locally Linear Embedding. What's new in version 2.4? -------------------------------------- - The new version introduces a new parallel package to execute the MDP algorithms on multiple processors or machines. The package also offers an interface to develop customized schedulers and parallel algorithms. Old MDP scripts can be turned into their parallelized equivalent with one simple command. - The number of available algorithms is increased with the Locally Linear Embedding and Hessian eigenmaps algorithms to perform dimensionality reduction and manifold learning (many thanks to Jake VanderPlas for his contribution!) - Some more bug fixes, useful features, and code migration towards Python 3.0 Resources --------- Download: http://sourceforge.net/project/showfiles.php?group_id=116959 Homepage: http://mdp-toolkit.sourceforge.net Mailing list: http://sourceforge.net/mail/?group_id=116959 -- Pietro Berkes Volen Center for Complex Systems Brandeis University Waltham, MA, USA Niko Wilbert Institute for Theoretical Biology Humboldt-University Berlin, Germany Tiziano Zito Bernstein Center for Computational Neuroscience Humboldt-University Berlin, Germany

ANN: gui_support, a convenience library for wxPython
by Stef Mientki Oct. 21, 2008

Oct. 21, 2008

hello, gui_support is library for easy creation of GUI designs in wxPython. Although it's quit stable, it's part of a larger project and therefor has a lot of dependencies, but these can easily be removed. Warning: Although this library might be very attractive to newbies, the use of this library will prevent you from learning some of the basics of GUI, specially of containers / sizers in wxPython. Brief documentation can be found here http://oase.uci.kun.nl/~mientki/data_www/pylab_works/pw_gui_support.html ( as this website will soon be moved, this docpage can always be found through the redirector http://pic.flappie.nl look under paragraph PyLab_Works | GUI_support ) Download: http://pylab-works.googlecode.com/files/Data_Python_Test.zip cheers, Stef

ANN: Shipyard 0.02
by Florian Diesch Oct. 19, 2008

Oct. 19, 2008

I'm happy to announce version 0.02 of the Shipyard python module <http://www.florian-diesch.de/software/shipyard/> ================= What is shipyard? ================= Shipyard is a module to process data in a format inspired by email headers (RFC 2822). The goal of shipyard is to have a simple, human readable and human writable replacement for CSV that works better for long data and many rows and doesn't need difficult escaping rules for special characters. It's called ``shipyard`` because that word contains ``py`` and doesn't seem to be taken yet. =========== File format =========== Character encoding ================== A character encoding can be specified similar to :pep:`0263` using:: # -*- coding: <encoding name> -*- in the first line. ``#`` is replaced with the actual `comment`_ mark. More precisely, the first line must match the regular expression:: ^#.*coding[:=]\s*([-\w.]+) Again ``#`` is replaced by the actual `comment`_ mark. The first group of this expression is then interpreted as encoding name. Data set ======== A *data set* consists of zero or more `records <#record>`__ separated by one or more empty lines. Comment ======= Lines starting with the *comment mark* (default: ``#``) are ignored. Comments can be used in or between `records <#record>`__. Record ====== A *record* consists of one or more `fields <#field>`__ Field ===== A *field* is a line that has the form:: key: value *key* is a string that - doesn't contain a colon - doesn't start with the `comment`_ mark - doesn't start with the `continuation`_ mark *value* is an arbitrary string. It can span multiple line using `continuation`_ marks. Continuation ============ If a line starts with the *continuation mark* (default: " " [one blank]) it gets appended to the preceding line, with the continuation mark removed. ===== Usage ===== Obviuosly we need to import shipyard: >>> import shipyard First we open the file: >>> input = open('nobel.sy') Then we create a parser object: >>> reader = shipyard.Parser(keep_linebreaks=False, ... keys=['id', 'discipline', 'year', ... 'name', 'country', 'rationale']) For every record the given keys are initialized with None. Now we can iterater through the records: >>> for record in reader.parse(input): # doctest:+ELLIPSIS ... print record['country'] United States Japan United States ... Instead of iterating we may want to get a list of dicts: >>> input.seek(0) >>> lod = reader.get_list(input) >>> print lod # doctest:+ELLIPSIS [{u'discipline': u'Chemistry', u'name': u'Martin Chalfie', ...}, {u'discipline': u'Chemistry', u'name': u'Osamu Shimomura', ...}, ...] Sometimes we need a dict of dicts (using the 'id' field as key): >>> input.seek(0) >>> dod = reader.get_dict(input, key='id') >>> print dod.keys() [u'11', u'10', u'1', u'0', u'3', u'2', u'5', u'4', u'7', u'6', u'9', u'8'] >>> print dod[u'5'][u'rationale'] for the discovery of the mechanism of spontaneous brokensymmetry in subatomic physics If we don't want dicts we can use the 'factory' parameter: >>> input.seek(0) >>> los = reader.get_list(input, factory = lambda **keys: ', '.join(keys.values())) >>> print los[0] Chemistry, Martin Chalfie, United States, for the discovery and development of the green fluorescentprotein, GFP, 2008, 0 Of course a class works as a factory, too: >>> input.seek(0) >>> class Laureate(object): ... def __init__(self, id, discipline, year, name, country, rationale): ... self.name = name >>> doo = reader.get_dict(input, key='id', factory = Laureate) >>> print doo[u'2'] # doctest:+ELLIPSIS <Laureate object at ...> >>> print doo[u'2'].name Roger Y. Tsien Now let's write a Shipyard file. First we create a StringIO (any other file-like object will do, too): >>> import StringIO >>> output = StringIO.StringIO() Next we need a Writer object: >>> writer = shipyard.Writer(keys=('foo', 'bar'), coding='utf-8') Now we can use write() to write a single record: >>> writer.write(output, {'foo': 1, 'bar': 2}) >>> print output.getvalue() foo: 1 bar: 2 <BLANKLINE> <BLANKLINE> Using write_many() we can write a list of records: >>> output = StringIO.StringIO() >>> d = [dict((('foo', i), ('bar', 2*i))) for i in range(3)] >>> writer.write_many(output, d) >>> print output.getvalue() foo: 0 bar: 0 <BLANKLINE> foo: 1 bar: 2 <BLANKLINE> foo: 2 bar: 4 <BLANKLINE> <BLANKLINE> To get a encoding line we use write_coding(): >>> output = StringIO.StringIO() >>> writer.write_coding(output) >>> print output.getvalue() #-*- coding: utf-8 -*- <BLANKLINE> <BLANKLINE> Now let's do everything at once using write_full(): >>> output = StringIO.StringIO() >>> writer.write_full(output, d) >>> print output.getvalue() #-*- coding: utf-8 -*- <BLANKLINE> foo: 0 bar: 0 <BLANKLINE> foo: 1 bar: 2 <BLANKLINE> foo: 2 bar: 4 <BLANKLINE> <BLANKLINE> Florian -- <http://www.florian-diesch.de/> ----------------------------------------------------------------------- ** Hi!

bzr 1.8 released
by Martin Pool Oct. 17, 2008

Oct. 17, 2008

I'm happy to announce the release of Bazaar 1.8. Bazaar 1.8 includes several fixes that improve working tree performance, display of revision logs, and merges. The bzr testsuite now passes on OS X and Python 2.6, and almost completely passes on Windows. The smartserver code has gained several bug fixes and performance improvements, and can now run server-side hooks within an http server. Thanks to everyone who contributed patches, suggestions, questions and bug reports. We welcome your feedback on this release to bazaar(a)lists.canonical.com or to #bzr on freenode. bzr 1.8 is now available for download from http://bazaar-vcs.org/Download as a source tarball; packages for various systems will be available soon. -- Martin bzr 1.8 2008-10-16 ------------------ Bazaar 1.8 includes several fixes that improve working tree performance, display of revision logs, and merges. The bzr testsuite now passes on OS X and Python 2.6, and almost completely passes on Windows. The smartserver code has gained several bug fixes and performance improvements, and can now run server-side hooks within an http server. BUG FIXES: * Fix "Must end write group" error when another error occurs during ``bzr push``. (Andrew Bennetts, #230902) PORTABILITY: * Some Pyrex versions require the WIN32 macro defined to compile on that platform. (Alexander Belchenko, Martin Pool, #277481) bzr 1.8rc1 2008-10-07 --------------------- CHANGES: * ``bzr log file`` has been changed. It now uses a different method for determining which revisions to show as merging the changes to the file. It now only shows revisions which merged the change towards your mainline. This simplifies the output, makes it faster, and reduces memory consumption. (John Arbash Meinel) * ``bzr merge`` now defaults to having ``--reprocess`` set, whenever ``--show-base`` is not supplied. (John Arbash Meinel) * ``bzr+http//`` will now optionally load plugins and write logs on the server. (Marius Kruger) * ``bzrlib._dirstate_helpers_c.pyx`` does not compile correctly with Pyrex 0.9.4.1 (it generates C code which causes segfaults). We explicitly blacklist that version of the compiler for that extension. Packaged versions will include .c files created with pyrex >= 0.9.6 so it doesn't effect releases, only users running from the source tree. (John Arbash Meinel, #276868) FEATURES * bzr is now compatible with python-2.6. python-2.6 is not yet officially supported (nor released, tests were conducted with the dev version of python-2.6rc2), but all known problems have been fixed. Feedback welcome. (Vincent Ladeuil, #269535) IMPROVEMENTS: * ``bzr annotate`` will now include uncommitted changes from the local working tree by default. Such uncommitted changes are given the revision number they would get if a commit was done, followed with a ? to indicate that its not actually known. (Robert Collins, #3439) * ``bzr branch`` now accepts a ``--standalone`` option, which creates a standalone branch regardless of the presence of shared repositories. (Daniel Watkins) * ``bzr push`` is faster in the case there are no new revisions to push. It is also faster if there are no tags in the local branch. (Andrew Bennetts) * File changes during a commit will update the tree stat cache. (Robert Collins) * Location aliases can now accept a trailing path. (Micheal Hudson) * New hooks ``Lock.hooks`` when LockDirs are acquired and released. (Robert Collins, MartinPool) * Switching in heavyweight checkouts uses the master branch's context, not the checkout's context. (Adrian Wilkins) * ``status`` on large trees is now faster, due to optimisations in the walkdirs code. Of particular note, the walkdirs code now performs a temporary ``chdir()`` while reading a single directory; if your platform has non thread-local current working directories (and is not windows which has its own implementation), this may introduce a race condition during concurrent uses of bzrlib. The bzrlib CLI will not encounter this as it is single threaded for working tree operations. (Robert Collins) * The C extensions now build on python 2.4 (Robert Collins, #271939) * The ``-Dhpss`` debug flag now reports the number of smart server calls per medium to stderr. This is in addition to the existing detailed logging to the .bzr.log trace file. (Andrew Bennetts) BUG FIXES: * Avoid random failures arising from misinterpreted ``errno`` values in ``_readdir_pyx.read_dir``. (Martin Pool, #279381) * Branching from a shared repository on a smart server into a new repository now preserves the repository format. (Andrew Bennetts, #269214) * ``bzr log`` now accepts a ``--change`` option. (Vincent Ladeuil, #248427) * ``bzr missing`` now accepts an ``--include-merges`` option. (Vincent Ladeuil, #233817) * Don't try to filter (internally) '.bzr' from the files to be deleted if it's not there. (Vincent Ladeuil, #272648) * Fix '_in_buffer' AttributeError when using the -Dhpss debug flag. (Andrew Bennetts) * Fix TooManyConcurrentRequests errors caused by a connection failure when doing ``bzr pull`` or ``bzr merge`` from a ``bzr+ssh`` URL. (Andrew Bennetts, #246233) * Fixed ``bzr st -r branch:PATH_TO_BRANCH`` where the other branch is in a different repository than the current one. (Lukáš Lalinský, #144421) * Make the first line of the manpage preamble a comment again. (David Futcher, #242106) * Remove use of optional parameter in GSSAPI FTP support, since it breaks newer versions of Python-Kerberos. (Jelmer Vernooij) * The autopacking logic will now always create a single new pack from all of the content which it deems is worth moving. This avoids the 'repack a single pack' bug and should result in better packing overall. (John Arbash Meinel, #242510, #172644) * Trivial documentation fix. (John Arbash Meinel, #270471) DOCUMENTATION: * Explain revision/range identifiers. (Daniel Clemente) API CHANGES: * ``CommitBuilder.record_entry_contents`` returns one more element in its result tuple - an optional file system hash for the hash cache to use. (Robert Collins) * ``dirstate.DirState.update_entry`` will now only calculate the sha1 of a file if it is likely to be needed in determining the output of iter_changes. (Robert Collins) * The PackRepository, RepositoryPackCollection, NewPack classes have a slightly changed interface to support different index types; as a result other users of these classes need to supply the index types they want. (Robert Collins) TESTING: * ``bzrlib.tests.repository_implementations`` has been renamed to ``bzrlib.tests.per_repository`` so that we have a common structure (and it is shorter). (John Arbash Meinel, #239343) * ``LocalTransport.abspath()`` now returns a drive letter if the transport has one, fixing numerous tests on Windows. (Mark Hammond) * PreviewTree is now tested via intertree_implementations. (Aaron Bentley) * The full test suite is passing again on OSX. (Guillermo Gonzalez, Vincent Ladeuil) * The full test suite passes when run with ``-Eallow_debug``. (Andrew Bennetts) INTERNALS: * A new hook, ``Branch.open``, has been added, which is called when branch objects are opened. (Robert Collins) * ``bzrlib.osutils._walkdirs_utf8`` has been refactored into common tree walking, and modular directory listing code to aid future performance optimisations and refactoring. (Robert Collins) * ``bzrlib.trace.debug_memory`` can be used to get a quick memory dump in the middle of processing. It only reports memory if ``/proc/PID/status`` is available. (John Arbash Meinel) * New method ``RevisionSpec.as_tree`` for representing the revision specifier as a revision tree object. (Lukáš Lalinský) * New race-free method on MutableTree ``get_file_with_stat`` for use when generating stat cache results. (Robert Collins) * New win32utils.get_local_appdata_location() provides access to a local directory for storing data. (Mark Hammond) * To be compatible with python-2.6 a few new rules should be observed. 'message' attribute can't be used anymore in exception classes, 'sha' and 'md5' modules have been deprecated (use osutils.[md5|sha]), object__init__ and object.__new__ don't accept parameters anymore.
