devpi 1.2 releases: many improvements + py33 support
The devpi-{server,client}-1.2 releases bring a lot of refinements
and improvements for serving and interacting with your own pypi indexes:
- devpi-server serves release files from URLs containing a MD5 hash
allowing safe serving of those files through nginx
- devpi-server's USER/INDEX urls can now be used directly with
pip/easy_install without the previously required (and still valid)
``+simple/`` suffix.
- ``devpi use --set-cfg`` reads and writes pip/easy_install
configuration files, making those installers pick up the in-use
index seemlessly. You can even do ``devpi use --always-set-cfg`` to
always set those config files when issuing a devpi use afterwards.
- ``devpi upload`` got many improvements:
- versioned files (git and hg) will be exported to a clean directory prior to
the build step
- distutils/setup.py is now only used for building a package
- documentation upload is tied to a version now
- you can directly upload distribution files, including wheel files
- both devpi-server and devpi-client are python3.3 compatible now and
depend on a new devpi-common package which consolidates various
pypi-interaction aspects to avoid code duplication. Also,
global http proxy settings are honoured.
If you have an existing devpi-server-1.1 installation serving
your own packages you can install devpi-server=1.2 and
migrate the data with::
devpi-server --upgrade-state [--serverdir your_server_dir]
This upgrades your server state in-place. Please make sure you
backup your serverdir ahead of doing the upgrade (default location
is ~/.devpi/server).
WARNING: ``devpi-server --gendeploy`` is deprecated and will be removed
probably in favor of just generating example config files for
nginx/supervisor/cron. Also ``devpi install`` is deprecated now
in favor of using pip/easy_install directly (see also the --set-cfg
and --always-set-cfg options).
For more information please refer to the extensive documentation at:
http://doc.devpi.net/

have fun,

1.2
devpi-server:
- serve links to files on simple pages and index root as relative
paths so that it works more nicely with proxy-pass server setups.
fixes issue56.
- make devpi-server and devpi-common python3.3 compatible, addresses
issue57
- use system http/s proxy settings from devpi-server. fixes issue58.
- refactor locations to allow nginx serving static files more directly.
Also updated nginx template accordingly.
- rework --upgrade-state to detect the state version of the server dir
and create an appropriate virtualenv with a devpi-server install in order
to export data, and then import that version.
- allow to use /user/index as indexserver url for pip/easy_install by
redirecting non-json queries to /user/index/PROJ[/] to
/user/index/+simple/PROJ/
- fix submission of multi-value fields like classifiers or platform
(previously they would be wrongly collapsed to become the last value of a
list)
- fix normalization import/export issue: pypi names take precendence
for defining the real name of a project.
- always store uploaded documentation with a version. While
devpi upload will make sure to pass in the version, setup.py upload_docs
will not pass in a version. In the latter case, devpi-server assumes
the documentation belongs to the highest yet registered release.
This change requires exporting with devpi-1.1 and importing with devpi-1.2
in order to properly store versioned docs internally.
- use types/url/metadata/validation functionality of new depdency devpi_common
- internal cleanup using pytest-flakes
- make devpi-server use a proper UserAgent string
devpi-client:
- devpi list and devpi remove now accept a pip/setuptools style
requirement like pkg=1.0 instead of the former for limited pkg-1.0.
- make devpi-client fully work with python3.3 and fix test bugs
- use system http/s proxy settings. fixes issue58.
- add devpi test -c tox.ini package to use a particular (external)
tox.ini for running tox with the unpackaged package.
also add --fallback-ini tox.ini option which will only
be used if the download package has no tox.ini.
- new devpi use --set-cfg option to set pip/easy_install configuration
files when changing indexes. Also new devpi use --always-set-cfg=yes
option if you want to imply --set-cfg on future devpi use invocations
and devpi use --always-st-cfg=no to disable this implication.
- support git and hg for exporting all versioned files of a directory
before performing the build step when uploading
- improve how upload works: setup.py is only used for building docs
and release files but not for the remote upload part. This gets rid of a
number of hacks that were done trying to get the Python shipped distutils
to pick the proper devpi index and allows proper SSL verification on Python2.6
onwards.
- upload: show response when uploading
ANN: NumPy 1.8.0 release.
I am pleased to announce the availability of NumPy 1.8.0. This release is the culmination of over a years worth of work by the NumPy team and contains many fixes, enhancements, and new features. Highlights are: - New, no 2to3, Python 2 and Python 3 are supported by a common code base. - New, gufuncs for linear algebra, enabling operations on stacked arrays. - New, inplace fancy indexing for ufuncs with the ``.at`` method. - New, ``partition`` function, partial sorting via selection for fast median. - New, ``nanmean``, ``nanvar``, and ``nanstd`` functions skipping NaNs. - New, ``full`` and ``full_like`` functions to create value initialized arrays. - New, ``PyUFunc_RegisterLoopForDescr``, better ufunc support for user dtypes. - Numerous performance improvements in many areas. This release requires Python 2.6, 2.7 or 3.2-3.3, support for Python 2.4 and 2.5 has been dropped. Sources and binaries can be found at http://sourceforge.net/projects/numpy/files/NumPy/1.8.0/. Some 119 people contributed to this release. This is a remarkable increase and shows that there is still life in this venerable code that had its beginning in Numeric some 18 years ago. Many thanks to you all. Enjoy, Chuck NumPy 1.8.0 Release Notes * This release supports Python 2.6 -2.7 and 3.2 - 3.3. Highlights == * New, no 2to3, Python 2 and Python 3 are supported by a common code base. * New, gufuncs for linear algebra, enabling operations on stacked arrays. * New, inplace fancy indexing for ufuncs with the ``.at`` method. * New, ``partition`` function, partial sorting via selection for fast median. * New, ``nanmean``, ``nanvar``, and ``nanstd`` functions skipping NaNs. * New, ``full`` and ``full_like`` functions to create value initialized arrays. * New, ``PyUFunc_RegisterLoopForDescr``, better ufunc support for user dtypes. * Numerous performance improvements in many areas. Dropped Support === Support for Python versions 2.4 and 2.5 has been dropped, Support for SCons has been removed. Future Changes == The Datetime64 type remains experimental in this release. In 1.9 there will probably be some changes to make it more useable. The diagonal method currently returns a new array and raises a FutureWarning. In 1.9 it will return a readonly view. Multiple field selection from a array of structured type currently returns a new array and raises a FutureWarning. In 1.9 it will return a readonly view. The numpy/oldnumeric and numpy/numarray compatibility modules will be removed in 1.9. Compatibility notes === The doc/sphinxext content has been moved into its own github repository, and is included in numpy as a submodule. See the instructions in doc/HOWTO_BUILD_DOCS.rst.txt for how to access the content. .. _numpydoc: https://github.com/numpy/numpydoc The hash function of numpy.void scalars has been changed. Previously the pointer to the data was hashed as an integer. Now, the hash function uses the tuple-hash algorithm to combine the hash functions of the elements of the scalar, but only if the scalar is read-only. Numpy has switched its build system to using 'separate compilation' by default. In previous releases this was supported, but not default. This should produce the same results as the old system, but if you're trying to do something complicated like link numpy statically or using an unusual compiler, then it's possible you will encounter problems. If so, please file a bug and as a temporary workaround you can re-enable the old build system by exporting the shell variable NPY_SEPARATE_COMPILATION=0. For the AdvancedNew iterator the ``oa_ndim`` flag should now be -1 to indicate that no ``op_axes`` and ``itershape`` are passed in. The ``oa_ndim == 0`` case, now indicates a 0-D iteration and ``op_axes`` being NULL and the old usage is deprecated. This does not effect the ``NpyIter_New`` or ``NpyIter_MultiNew`` functions. The functions nanargmin and nanargmax now return np.iinfo['intp'].min for the index in all-NaN slices. Previously the functions would raise a ValueError for array returns and NaN for scalar returns. NPY_RELAXED_STRIDES_CHECKING There is a new compile time environment variable ``NPY_RELAXED_STRIDES_CHECKING``. If this variable is set to 1, then numpy will consider more arrays to be C- or F-contiguous -- for example, it becomes possible to have a column vector which is considered both C- and F-contiguous simultaneously. The new definition is more accurate, allows for faster code that makes fewer unnecessary copies, and simplifies numpy's code internally. However, it may also break third-party libraries that make too-strong assumptions about the stride values of C- and F-contiguous arrays. (It is also currently known that this breaks Cython code using memoryviews, which will be fixed in Cython.) THIS WILL BECOME THE DEFAULT IN A FUTURE RELEASE, SO PLEASE

I have been away from my Internet connection for several days and could not respond to them when they were first posted here. The comments have all been considered. And I am discussing them with other researchers that I work with. Since Perl has a calculation speed limit that is probably not easy to get around, before too long another language will be selected for initially doing certain things such as performing calculations and plotting charts. And the existing Perl code might then be gradually translated into that new language. Gnuplot is presently being used to draw charts. And it works. But it has its own limitations such as with its interaction speed when it is used for working with Perl program generated data files. My main, complex programs won't be run at Web sites. They will instead continue to be available as downloadable exe programs. The CGI (or whatever) programming work would involve relatively simple programs. But they would need to be able to generate charts that would be displayed on Web pages. That sounds like it is probably fairly easy to do using Python. A Perl - Gnuplot combination is also supposed to be able to do that. But so far I have not seen any good explanations for how to actually get Gnuplot to run as a callable CGI program. So other programs such as Python are being considered. -- https://mail.python.org/mailman/listinfo/python-list

zero argument member functions versus properties
Python makes it very easy to turn a zero argument member function into a property (hooray!) by simply adding the @property decorator. (Meme for well thought py feature - Guido was here) But the ease with which you can do this makes the zero argument member function or property discussion trickier for me. Generally my sense here is there are two extremes 1- the zero argument function is sort of factory-like. It potentially has non-trivial run time, or it substitutes calling a class constructor when building certain objects. 2- it simply retrieves a stored value (perhaps lazily evaluating it first) so 1 should clearly be a zero argument member function. 2 should be a method. Other than that, I say when in doubt, go with zero argument method. In particular something in my gut says that if the thing I'm returning is itself a function, than don't go with property. In other words foo.bar()(x) self documents that bar returns a function whereas foo.bar(x) looks like bar is a one argument member function of foo, as opposed to a property that returns a 1 argument function I also think that foo.size() implies that foo performs a count every time it's called, and foo.size implies that the run time will amortize to O(1) somehow (usually with lazy eval). So the implementation should drive the property or not decision. Sound a bit right? Seems like some of the energetic posters will have fun with this one, re:less. -- https://mail.python.org/mailman/listinfo/python-list

(Meme for well thought py feature - Guido was here) It is well-thought out, but it's also quite late in Python's history. Properties didn't get added until new style classes and descriptors, which was in version 2.2. I'm not sure if it's Guido to thank for them. But the ease with which you can do this makes the zero argument member function or property discussion trickier for me. Generally my sense here is there are two extremes 1- the zero argument function is sort of factory-like. It potentially has non-trivial run time, or it substitutes calling a class constructor when building certain objects. 2- it simply retrieves a stored value (perhaps lazily evaluating it first) I normally go with something like this: Something with a significant overhead (e.g. memory or running time) should be a method. The fact that you have to call it is a hint that it may require non-trivial resources/time to perform. On the other hand, something that feels like it ought to be an inherent attribute of an object should be a property if you need it to be lazily calculated, or a standard attribute if you want to give direct access to it. For example, imagine an object representing a printable page. The paper size (A4, A3, foolscap, etc.) is an inherent attribute of a page, so it ought to be accessed using attribute notation: mypage.size If this is lazily generated, or if you want to protect the attribute with data validation, you should use a property. Otherwise, an ordinary data attribute is acceptable. (This isn't Java or Ruby, where data-hiding is compulsory :-) On the other hand, the Postscript image of the page is not inherent to the page, and it is also expensive to generate. So it ought to be generated lazily, only when needed, but using method notation: mypage.postscript() Page margins are intermediate. They feel kind of inherent to a page, but not exactly -- in a complex document, the margins may depend on the section you are in. Margins can vary depending on whether the page is at the left or the right. So page margins probably ought to be computed attributes. But they probably won't be terribly expensive to compute. So here I would again go with a property, assuming the page object knows whether it is on the left or the right, and which section it belongs to. But if somebody else decided that margins ought to be an explicit method, I wouldn't consider them wrong. It is a matter of personal taste. [...] I also think that foo.size() implies that foo performs a count every time it's called, and foo.size implies that the run time will amortize to O(1) somehow (usually with lazy eval).

And the existing Perl code might then be gradually translated into that new language. The nice things about Python are that it makes a great glue language for putting together components written in low-level languages like C and Fortran, and that there is a rich ecosystem of products for speeding it up in various ways. So when you hit the speed limits of pure Python, you have lots of options. In no particular order: * try using another Python compiler: PyPy is probably the most mature of the stand-alone optimizing compilers, and you can expect to double the speed of typical Python code, but there are others; * use numpy and scipy for vectorized mathematical routines; * re-write critical code as C or Fortran libraries; * use Pyrex (possibly unmaintained now) or Cython to write C extensions in a Python-like language; * use Psyco or Numba (JIT specialising compilers for Python); * use Theano (optimizing computer algebra system compiler); * use ctypes to call C functions directly; * use other products like Boost, Weave, and more.

It's not as clear-cut as it looks in C#. Although refactoring the class in this way doesn't change the API, it does break ABI, which is significant in an environment where virtually everything is distributed in binary form. This happens because a property access compiled to CIL byte code is transformed into a call to a getter or setter method, which is a distinct operation from an ordinary attribute access. Whereas in Python, an attribute access is just compiled as an attribute access no matter what the underlying implementation of that access may end up being at run-time. -- https://mail.python.org/mailman/listinfo/python-list

The recommended way is to use a secondary table, as has been pointed out. Most SQL databases allow you to store arbitrary data as an opaque value (i.e. BLOB).

The limitation, of course, is that the data is opaque as far as the database goes; you can't do queries against it.

As print is now a function, you're going to need to construct a

[snip reasons] But your second reason, better known as the pigeonhole principle, demonstrates that for any lossless compression method, there must be data sets that actually expand the data. It doesn't matter how cleverly you compress the data, you can't fit 20kg of potatoes in a 10kg bag, so to speak. Suppose your compression algorithm compresses a single byte into a nybble (four bits). There are 256 different input data sets (0x00, 0x01, ... 0xFF) and only 16 different outputs (0x0, 0x1, ... 0xF). There is no way for 256 pigeons to fit in 16 pigeon holes unless you put two or more pigeons in at least one hole. Ergo, if the compression algorithm is lossless, *some* data must be expanded rather than compressed. You have to be careful to make this totally rigorous, too. Note that I *can* make a compression algorithm that takes any length-n sequence and compresses all but one sequence by at least one bit, and does not ever expand the data. 00 - 01 - 0 10 - 1 11 - 00 This, obviously, is just 'cause the length is an extra piece of data, but sometimes you have to store that anyway ;).

[my emphasis] The implication, that the OP does not have any programming experience, will be clear to anyone with with even mediocre English speaking ability. The semantic information conveyed to the OP is the same as the statement of fact, you have no programming experience and it is perfectly valid to claim that you told the OP that he had no programming experience. I pointed this out in nearly every email but in every one of your responses to it, you ignore that concluding sentence and mention *only* your initial questioning sentence to justify your assertion that you posed it as a question. As an aside, you shouldn't rely on that initial question sentence so much either -- just because something is framed as a question does not mean its intent is not to attack: excuse me for asking, but are you an asshole? You asked, have you *ever* done *any* programming *at all*?

My claims of ad hominem and attack follow from the fact that you *did* tell the OP he had no programming experience, in direct contradiction to what he had stated, and with no evidence to support your claim beyond the OP's opinions on loops and goto's. Each time I have responded to you, I have given direct quotes and directly addressed the substance of your posts, which is all to do with the supposed tone of my response to the OP. Each time you have continued to misrepresent me, misquote me, and interpret my words assuming bad faith rather than good, in order to justify your idea that my post was an ad hominem attack. Including this post, where you make the false statement that: [quote] His idea was that loop tests should always or usually be done at the end of the loop. You discussed *nothing* that supported that idea. Emphasis yours. But in fact I gave the concrete example of Pascal repeat...until loops, which have the test at the end of the loop. So yet again your claims are simply wrong. That was an unfortunate example for you to chose since it directly contradicts your claims. Read that quote again. You are a programmer. You should understand logic. Please explain how acknowledging *one* useful end-of-loop construct supports the idea that /quote/ loop tests should *always or usually* be done at the end of the loop /endquote/, especially when you present it with long string of cases where testing at the bottom is *not* desirable. You did not agree with the OPs idea that the test should *always* go at the end of the loop and I represented your opinion as such. This was pointed out to you before yet you continue to claim I am misrepresenting you. This is four posts in a row now that you have wrongly represented me. I can only conclude that you think that by repeating a lie often enough, you'll convince others that it must be true and win. In my preceding post, I pointed out your practice of repeating the same discredited accusations in the the hope that repeating them enough would somehow make them true... It is amusing to see you lift my own words to use against me (although I used the word accusation and you choose to use the word lie -- a difference in our standards I guess.) I misrepresented you once, immediately acknowledged and corrected it when you pointed it out. You have continued to accuse me of misrepresenting you in *every* post you've made, while refusing to respond to my request to tell me how you think you *should* be paraphrased.

Run gnuplot and point it to the file of commands (e.g., 'gnuplot gunplot.cmd') . How this is done depends upon the CGI program language (see below). 3.

Hey everyone, As time progresses, so does my Redis object mapper. The rom package is a Redis object mapper for Python. It sports an interface similar to Django's ORM, SQLAlchemy + Elixir, or Appengine's datastore. The changelog for recent releases can be seen below my signature. You can find the package at: https://www.github.com/josiahcarlson/rom https://pypi.python.org/pypi/rom And docs can be found at: http://pythonhosted.org/rom/ Please CC me on any replies if you have any questions or comments. Thank you, - Josiah #--- 0.22 [fixed] size estimation for intersection ordering when filtering has now been fixed, thank you to https://github.com/MickeyKim for the report and the change (should improve performance). [fixed] an issue with some types when trying to update attributes has now been fixed, thank you to https://github.com/denisvolokh for the report. [changed] improved performance for simple numeric range queries of the form Model.get_by(attr=value) or Model.get_by(attr=(min, max)) by roughly a factor of 60x or better in some cases. Thank you to https://github.com/MickeyKim for the report on poor performance. #--- 0.21 [fixed] upload for rom 0.20 was missing new columns.py, now fixed #--- 0.20 [changed] Added exception when performing .all(), .execute(), or .count() on query objects that have had no filters or attribute ordering provided. This addresses issue #12. [changed] Moved column definitions to their own module, shouldn't affect any normal uses of rom. [added] For users of Redis 2.6 and later, there is a beta Lua-enabled writing option that allows for multiple unique columns on models. In some cases, this may improve performance when writing many entities very quickly. [added] The ability to reload an entity from Redis, optionally discarding any modifications to the object itself. Check out the documentation for Model.refresh(), Session.refresh(), and Session.refresh_all() [added] Tests for the newly changed/added features. [changed] Tests no longer use flushdb() - all test models/indexes/etc. are prefixed with RomTest, and we find/delete such keys before and after any tests are run. Now anyone can reasonably run the test suite. #--- 0.19 [fixed] Thanks to a bug report by https://github.com/MickeyKim , was notified of a bug when using unique indexes, which is now fixed and has a testcase. -- https://mail.python.org/mailman/listinfo/python-list

Write a file with gnuplot commands (e.g., 'gnuplot.cmd') that set the output device to a graphics file of some format (e.g., PNG), generate a plot, and quit gnuplot.

Problem installing matplotlib 1.3.1 with Python 2.7.6 and 3.3.3 (release candidate 1)
Hello, I tried to install matplotlib 1.3.1 on the release candidates of Python 2.7.6 and 3.3.3. I am on Mac OS X 10.6.8. Although the installation gave no problems, there is a problem with Tcl/Tk. The new Pythons have their own embedded Tcl/Tk, but when installing matplotlib it links to the Frameworks version of Tcl and TK, not to the embedded version. This causes confusion when importing matplotlib.pyplot: objc[70648]: Class TKApplication is implemented in both /Library/Frameworks/Python.framework/Versions/2.7/lib/libtk8.5.dylib and /Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined. objc[70648]: Class TKMenu is implemented in both /Library/Frameworks/Python.framework/Versions/2.7/lib/libtk8.5.dylib and /Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined. objc[70648]: Class TKContentView is implemented in both /Library/Frameworks/Python.framework/Versions/2.7/lib/libtk8.5.dylib and /Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined. objc[70648]: Class TKWindow is implemented in both /Library/Frameworks/Python.framework/Versions/2.7/lib/libtk8.5.dylib and /Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined. And then later it gives a lot of error messages. So I think it should be linked to the embedded version. For this the matplotlib setupext.py should be adapted to find out if there is an embedded Tcl/Tk in the Python installation and set the link parameters accordingly. However, the installed Python versions (from the DMG's) do not contain the Tcl/Tk header files, only the shared library and the tcl files. So I thing the distributed Python should also include the Tcl/Tk header files. -- Piet van Oostrum p...@vanoostrum.org WWW: http://pietvanoostrum.com/ PGP key: [8DAE142BE17999C4] -- https://mail.python.org/mailman/listinfo/python-list

Re: Algorithm that makes maximum compression of completly diffused data.
Note that I *can* make a compression algorithm that takes any length-n sequence and compresses all but one sequence by at least one bit, and does not ever expand the data. 00 - 01 - 0 10 - 1 11 - 00 This, obviously, is just 'cause the length is an extra piece of data, but sometimes you have to store that anyway ;). And how many bits will you use to store the length? So if I have a list of N length-Y lists containing only 1s or 0s, I can genuinely compress the whole structure by N log2 Y items. But you cheated by using a piece of information from outside the system: length. A generic compression algorithm doesn't have this information beforehand. -- MarkJ Tacoma, Washington -- https://mail.python.org/mailman/listinfo/python-list

But for dealing with xls files, I recommend saving to and reading from .csv files; Python deals great with these. If you're not concerned about getting (further) locked into a dying, binary-only platform, you could use xlrd and xlwt though. It looks like xlrd runs on 2.x and 3.x, while xlwt is still 2.x only - that's another reason to go with csv, which works well with 2.x and 3.x for reading and writing. -- https://mail.python.org/mailman/listinfo/python-list

[issue19483] Pure-Python ElementTree classes no longer available since 3.3
New submission from Brecht Machiels: With Python 3.2, I subclassed ElementTree.XMLParser to set ExternalEntityRefHandler on the XMLParser's (expat) 'parser' member. I understand the 'parser' member is not part of the public API, but this was the only way to customize the parser without having to write a parser from scratch. With 3.3, cElementTree replaces the Python implementation by default. Its XMLParser class has no accessible 'parser' member to configure. Unfortunately, there does not seem to be a way to use the pure-Python XMLParser, which would still allow for customization of the parser. Why is the Python version still in the library if it can't be accessed? Only for platforms where the C extension is not available? I see two possible solutions: 1) Have XMLParser (both the C and Python versions) accept an optional parser argument, so that a custom parser can be passed in. 2) Make the Python version of ElementTree available again. My other option is to copy the Python XMLParser version into my project. I would like to avoid this, as this would duplicate a lot of perfectly good code. Perhaps there are other solutions? -- components: XML messages: 202011 nosy: brechtm, eli.bendersky, scoder priority: normal severity: normal status: open title: Pure-Python ElementTree classes no longer available since 3.3 type: behavior versions: Python 3.3, Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19483 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
