By the way, I think I have found the correct wording. for my understood, the handover of objects to imported modules doesn't work because, e.g. trying to hand-over an SQLite connection into a imported module, can't work because the attributes are not transfered. I'm sorry for my bad english, it's fascinating. 2 years ago I've written very large english technical documents for my company.

Maybe you should post some of the Perl code, in small pieces. Then we can suggest ways those poarticular things might be done in Python. Python threads really easily (with some limitations, but for many purposes those limitations are irrelevant). When I have a situation like yours seems to be, I tend to write a few different items, connected together with a main program. Write modules that define a class for the things you need to talk to: the database, the sensors, etc. From the main program, create an instance of the relevant classes, then dispatch threads doing what needs to be done. The main program might be shaped like this: import db_module # use a better name # defines a class called DB to talk to a # database import sensors_module # use a better name # defines a class called Sensors to report # sensor values def thread_function(db, sensors): ... do something that should happen in a thread ... # get some objects to connect to db and sensors db = db_module.DB(connection-info-here...) sensors = sensors_module.Sensors(sensor-connection-info-here...) # set up a Thread and start it T = Thread(target=thread_function, args=(db, sensors)) T.start() ... create other threads as needed ... You see here that: - the modules do not know _specifics_ about the db or sensors; they are told connection info - instantiating a class instance: db = db_module.DB(connection-info-here...) passes the specifics - you get back a class instance - you pass those instances (db, sensors) to the thread_function; it uses them to access database and sensors So you see that the modules do not directly share information with each other. The main program gets objects from each module and hands them to whoever needs to work with them. Does this clarify your namespace issues?

Parsing files in python
Hello: I am writing a program that is made up of a collection of POV-Ray macros. POV-Ray is available at povray.org. It is a ray-tracing program that reads a scene description language (SDL) to create photo-realistic images. At this time my program (for modeling building information) is so huge that I am finding it difficult managing the macros and I am not even near completion. I am hoping to move this program to python and am wondering the best way to approach this. I would like to model my program after LaTeX. Basically the user writes a text file using certain key words and numbers and my python program reads this file, calls the classes that will then work together to calculate the information that is needed to create an accurate model. The result of this calculation will be an output to another text file in the appropriate format such as POV-Ray SDL, OpenSCAD script, etc. This file output can then be rendered by the corresponding program to produce the actual 3D model. The macros I have now currently does this but like I said it is getting tedious and most importantly the fun factor is losing its strength for me. I have been advised to check out python-ply and I have come across others. I have not really tried any yet and before I dive into any one of them I was wondering what else I should know. The following is a sample of what the text file that will be processed by this proposed system will contain. I appreciate any pointers and suggestions. Thank you very much. possible user file content for parsing // in the following the python interface program reads //+ the contents of the file other.file as if its content //+ were located at this point. include other.file //In the following the python interface makes snap_size a //+ global parameter declare snap_size = 10 // In the following buildingLevel is a class that is //+ called and passed the parameters in parenthesis. buildingLevel(FirstLevel, 3000) // In the following snapOffset is a class that is //+ called and passed the parameters in parenthesis. snapOffset(Closet-S1_r1, Closet-S2_r3, 0,0,0) end of user file content It should also be possible to include comments using double-slashes, etc. Sincerely, Kene (kemen...@gmail.com) -- http://mail.python.org/mailman/listinfo/python-list

Maybe a few hundred million characters, but i haven't tried beyond that. i suspect the limit you're hitting is the limit of subject size in an email protocol. In particular, the 3rd argument to sendmail() needs to have newlines in a particular format before you get to the body of the email. The body can be quite large, but you probably are required to have the appropriate headers first. When you send a short message, does it all come out as a subject line?

The macros I have now currently does this but like I said it is getting tedious and most importantly the fun factor is losing its strength for me. I have been advised to check out python-ply and I have come across others. I have not really tried any yet and before I dive into any one of them I was wondering what else I should know. The following is a sample of what the text file that will be processed by this proposed system will contain. I appreciate any pointers and suggestions. Mine is Don't do that. Seriously. What I understand is that you are proposing to design and write a parser for yet another Domain Specific Language -- that will require knowledge to use that is useless outside the specific domain. I expect that is will come to duplicate the basic facilities of existing languages. Users will want to be able to calculate, make conditional calculations and constructions, iterate*, and define functions (subroutines, macros). Why bother to reinvent all that? It often becomes a mess. (Or you will offer or people will want to mix Python with the dsl. That also can become a mess.) Instead, write a pypovray package incorporating the POV macros, that can be imported into a python program. Write a tutorial for the specific parts of Python that users will need. For instances, someone wants to place duplicate or parameterized models on a rectangular grid, along an arc, or even at random locations. possible user file content for parsing // in the following the python interface program reads //+ the contents of the file other.file as if its content //+ were located at this point. # this is a python comment. trivial difference from // include other.file import other.file # with Python's variations # or exec(open('other.file')) # but it is nearly always better to # keep the separate namespace.

?????? compile python 3.3 with bz2 support
Finally I worked it out. I write it down Here to people who meet the same problem like me. 1. Install bzip2 from source is OK 2. There is no need to add --with-bz2 to ./configure, because it is not a valid param. python makefile will search the bz2 itself, if it find the bz2 lib, it will automatically compile this module. see setup.py line 1373. So the ./configure outputs the warning : configure: WARNING: unrecognized options: --with-bz2 3. The reason why I failed before is that I did not correctly compile the bz2.so, the filename _bz2.cpython-33m_failed.so has indicated that fact. And the reason why I faild to compile bz2.so is strangely the RedHat SELinux. So the only thing I then do is disable it (setenforce 0), after that, everything is OK.

[issue16754] Incorrect shared library extension on linux
New submission from Sandro Mani: I'm using Python3 as available in Fedora rawhide (python3-3.3.0-2.fc19.x86_64). Attempting to build a project using python3/distutils, I noticed that find_library_file would not find any library at all. Some investigation showed that this was due to the fact that libraries were searched with the .cpython-33m.so extension. Even more investigation showed that the library extension was read being overridden by the one defined in the /usr/lib64/python3.3/config-3.3m/Makefile shipped by python3-libs. See below for the detailed analysis. The python-versioned extension obviously makes no sense for regular shared objects which are not python binary modules, so this is clearly wrong. As a workaround I patched sysconfig.py to comment out customize_compiler::235 (compiler.shared_lib_extension = so_ext, see below), recompiled python (all tests still pass), and things seem to work. Detailed analysis: setup.py: def _find_library_file(self, library): return self.compiler.find_library_file(self.compiler.library_dirs, library) --- In function /usr/lib64/python3.3/distutils/unixcompiler.py at find_library_file::266: shared_f = self.library_filename(lib, lib_type='shared') In function /usr/lib64/python3.3/distutils/ccompiler.py at library_filename::882: ext = getattr(self, lib_type + _lib_extension) - Where does shared_lib_extension get defined? * At /usr/lib64/python3.3/distutils/ccompiler.py::66 shared_lib_extension = None - default for abstract class * At /usr/lib64/python3.3/distutils/unixcompiler.py::77 shared_lib_extension = .so - this is the correct value * In function /usr/lib64/python3.3/distutils/sysconfig.py at customize_compiler::235 by /usr/lib64/python3.3/distutils/sysconfig.py at customize_compiler::235 compiler.shared_lib_extension = so_ext by /usr/lib64/python3.3/distutils/sysconfig.py at customize_compiler::194 (cc, cxx, opt, cflags, ccshared, ldshared, so_ext, ar, ar_flags) = \ get_config_vars('CC', 'CXX', 'OPT', 'CFLAGS', 'CCSHARED', 'LDSHARED', 'SO', 'AR', 'ARFLAGS')) by /usr/lib64/python3.3/distutils/sysconfig.py at get_config_vars::530 526 global _config_vars 527 if _config_vars is None: 528 func = globals().get(_init_ + os.name) # - os.name = posix 529 if func: 530 func() # - _init_posix, populates _config_vars by /usr/lib64/python3.3/distutils/sysconfig.py at _init_posix::439 435 g = {} 436 # load the installed Makefile: 437 try: 438 filename = get_makefile_filename() # /usr/lib64/python3.3/config-3.3m/Makefile 439 parse_makefile(filename, g) ... 476 global _config_vars 477 _config_vars = g # - _config_vars[SO] = .cpython-33m.so by /usr/lib64/python3.3/config-3.3m/Makefile::122 SO= .cpython-33m.so -- assignee: eric.araujo components: Distutils messages: 177979 nosy: eric.araujo, smani, tarek priority: normal severity: normal status: open title: Incorrect shared library extension on linux type: behavior versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16754 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15302] Use argparse instead of getopt in test.regrtest
Chris Jerdonek added the comment: The reason in part is because of the lack of unit tests of regrtest (as commenters above have noted). By preserving the getopt interface, we can keep almost all of the untested code as is. You should view the patch as a first step in refactoring to use argparse. We can remove the conversion code and the main for loop in later steps. Note to committers: I was meaning to rename regrlib.py when I was working on this. Until regrtest-related code is in its own subpackage, I think the file name should begin with regrtest -- perhaps regrtester.py or regrtestlib.py. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15302 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Serhiy Storchaka added the comment: As I understand, the issue is that mmap slicing returns an empty string for large (but less than ssize_t limit) indices on 2.7. May be it relates to 30-bit digits long integer implementation? -- nosy: +serhiy.storchaka ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16743 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15302] Use argparse instead of getopt in test.regrtest
Chris Jerdonek added the comment: Yes, I agree with all of that but thought it would be easier to review if done incrementally as separate steps.

[issue7263] Fix set.intersection docstring
Juan Benavente Ponce added the comment: Comparing the docstrings with the on-line documentation, I have found that, in addition to the already mentioned issue, the fact that many methods only require the first argument to be a set (or frozenset) object is not mentioned anywhere in the docstrings. Would it be useful if I write here a list of all the cases where this happens, and a possible alternative? An example: Python 2.7 set.union current docstring: Return the union of sets as a new set. (i.e. all elements that are in either set.) possible enhancement: union(set1, *iterables) -- new set Return a new set with elements from set1 and all the iterables. Would it be a good idea to create a different docstring for the bound method? E.g: unbound version: union(set1, *iterables) -- new set Return a new set with elements from set1 and all the iterables. bound version: set1.union(*iterables) -- new set Return a new set with elements from set1 and all the iterables. If writing this list would be useful, please tell me so, and I will do it.

[issue16712] collections.abc.Sequence should not provide __reversed__
Raymond Hettinger added the comment: Guido put a number of non-optimal implementations in the ABCs. His goal was to define the interface and to supply a working default implementation (see MutableMapping.clear() for a prime example). In the case of __reversed__(), it is unfortunate that it slows down the default implementation of reverse(). The latter only runs faster because it is in C, not because of any algorithmic issue. FWIW, the same is also true of Sequence.__contains__(). This logic in the ABC is straight-forward but slows down the code as compared to Python's C optimizations which can infer a __contains__ method from a sequence that defines __getitem__(). Given that the issue isn't algorithmic and is merely a C vs pure Python issue, I recommend leaving the current code as-is. If someone truly cares about the speed issue, it would be an easy matter to supply a C helper function in the ABCs for speeding-up __reversed__ and __contains__ (for an example of how to do this, see _count_elements() in the collections module). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16712 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16743] mmap accepts files 1 GB, but processes only 1 GB
Terry J. Reedy added the comment: To me, Marc's title and penultimate sentence imply that he thinks that mmap should not accept such files. (But he should speak for himself.) As I said, not accepting such files could break working code. As for the alternative of 'fixing' methods: Is it only slicing or other methods, even *every* method that 'misbehaves' when attempting to read (or write) beyond the 1 gig limit? I am guessing the last. If so, just about every method (inherited from bytearray, like slicing, or mmap specific) would need a fix conditional on the build and access location (and OS or hardware?). Even for slices, what change would you (or anyone) make? Keep in mind that is it a *feature* of slices that they generally always work, and that this is specifically true of bytearrays. (Memory-mapped file objects behave like both bytearray and like file objects.) I am actually a bit surprised that the limit is 1 gb rather than 2, 3, or 4 gb. Is it the same on *nix? What is the limit for a bytearray on Win 7? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16743 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
