Lantz - automation and instrumentation in Python
Today I am releasing Lantz, a Python automation and instrumentation toolkit that allows you to control instruments in a clean and efficient manner writing pure Python code. For more information you can read the full announcement here [0] or look into the documentation [1] (or in the github mirror: [2]) It is BSD licensed and there is a public GitHub repo if you want to check out the code [3] [0] http://python-in-the-lab.blogspot.de/ [1] http://lantz.glugcen.dc.uba.ar/ [2] http://hgrecco.github.com/lantz/ [3] https://github.com/hgrecco/lantz -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
cx_Freeze 4.3
What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables, in much the same way that py2exe and py2app do. Unlike these two tools, cx_Freeze is cross platform and should work on any platform that Python itself works on. It supports Python 2.3 or higher, including Python 3. Where do I get it? http://cx-freeze.sourceforge.net What's new? The release notes can be read here as well: http://cx_freeze.readthedocs.org/en/latest/releasenotes.html 1) Added options to build Mac OS X application bundles and DMG packages using bdist_mac and bdist_dmg distutils commands. Written by Rob Reilink. 2) The documentation is now using Sphinx, and is available on ReadTheDocs.org. 3) Added support for Python 3.3 which uses a different compiled file format than earlier versions of Python. 4) Added support for Windows services which start automatically and which are capable of monitoring changes in sessions such as lock and unlock. 5) New cxfreeze-quickstart wizard to create a basic setup.py file. Initially written by Thomas Kluyver. 6) Included files under their original name can now be passed to include_files as a tuple with an empty second element. Written by r_haritonov. 7) File inclusions/exclusions can now be specified using a full path, or a shared library name with a version number suffix. Bugs fixed: 1) Messagebox display of certain errors in Windows GUI applications with Python 3. (Issue 3486872) 2) Running Windows GUI applications in a path containing non-ASCII characters. 3) Calculate the correct filename for the Python shared library in Python 3.2. (Issue 3411270) 4) Including a package would not include the packages within that package, only the modules within that package.

In the code sample provided, you will see that the label widgets
stacked on each row will block click events on the containing
rowFrames below them. You can get a click event (on the sub frames)
to work by clicking the exaggerated border on the frames. All the
events work properly for me, although this GUI interface seems
unintuitive even with proper borders and colors.
Fredric, I can't help but feel that you are not attacking the problem
correctly. Please explain the following questions in detail so that i
may be able to provide help:
It works for me too.
I spent another day running the offending class in a simplified
environment and it worked flawlessly. In what way the environment makes
the difference is anything but obvious. But it has got to be the
environment.
Q1. You have subclassed a Tkinter.Frame and you are building rows of
sub-frames into this toplevel frame; with each row holding
horizontally stacked label widgets. Okay, I can see a need to wrap up
a RowFrame object, but i don't see a need to create a
RowFrameFactory. Can you explain this design decision?
I sent this same response yesterday with a screen shot attached. The
message didn't pass. It must have been rejected by a spam filter. So I
try again without the screen shot. (Too bad. A picture is worth a
thousand words).
The hit list is a table of investment titles (stock, funds, bonds)
that displays upon entry of a search pattern into a respective template.
The table displays the matching records: name, symbol, ISIN, CUSIP, Sec.
Any line can be click-selected. So they are to look like buttons.
Representing the mentioned names and id codes in Label widgets was the
simplest way I could come up with to align them in columns, admittedly
without the benefit of much experience. But it does look good. the
layout is fine.
I find the Tkinter system quite challenging. Doing a layout isn't so
much a matter of dimensioning and placing things as a struggle to trick
a number of automatic dimensioning and placing mechanisms into
obliging--mechanisms that are rather numerous and hard to remember.
Q2. It seems odd to me that you want to engage the rowFrame widgets
via events but NOT the Label widgets. Can you explain this design
decision?
Again, the labels serve to align the fields into columns. As to the
bindings, I just now found out, that Entry and Leave can be bound to
the line frame, but the mouse buttons don't act on the frame with the
labels covering it wall to wall. Entry will lighten up the background of
the line. Leave restores the normal color. ButtonRelease-N will select
the line, darkening the text. The coloring has to be done separately on
each label across the line, as the labels cover the frame. That isn't a
problem.
I'm sorry

Cheers, Daniel Your expectations are reasonable. You forget to finish that sentence. Your expectations are reasonable, for languages that don't have variables which can actually vary. *wink* For purely functional languages like Haskell, the behaviour you show below makes sense.

My comment was direct result of Christian stating: (paraphrase) On some systems you are not permitted to delete a file whilst the file is open ...which seems to be consistent to me. Why would *anybody* want to delete a file whilst the file is open? Because it is useful and a sensible thing to do. Why should one misbehaved application, keeping a file open, be allowed to hold every other application, and the file system, hostage? This is one of the many poor decisions which makes Windows so vulnerable to viruses and malware. If malware can arrange to keep itself open, you can't delete it. Thanks guys! Bringing back the car analogy again: Would you consider jumping from a moving vehicle a consistent interaction with the interface of a vehicle? Of course not. The interface for a vehicle is simple and consistent: 1. You enter the vehicle at location A 2. The vehicle transports you to location B 3. You exit the vehicle Amusingly, you neglected to specify the vehicle stops -- and rightly so, because of course having to stop the vehicle is not a *necessary* condition for exiting it, as tens of thousands of stunt men and women can attest. Not to mention people parachuting out of an airplane, pirates or commandos boarding a moving ship, pedestrians transferring from a slow moving walkway to a faster moving walkway, farmers jumping off a trailer while it is still being towed behind a tractor (and jumping back on again), and Bruce Willis in Red in very possibly the best slow-motion action sequence in the history of Hollywood. http://www.youtube.com/watch?v=xonMpj2YyDU At no time during the trip would anyone expect you to leap from the vehicle. Expected or not, you can do so. But when you delete open files, you are essentially leaping from the moving vehicle! This behavior goes against all expectations of consistency in an API -- and against all sanity when riding in a vehicle! Fortunately, files on a file system are not cars, and deleting open files is a perfectly reasonable thing to do, no more frightening than in Python deleting a reference to an object using the del statement. Imagine how stupid it would be if this happened: py x = 42 py y = x py del y Traceback (most recent call last): File stdin, line 1, in module DeleteError: cannot delete reference to object '42' until no other references to it exist Fortunately, Python doesn't do that -- it tracks when the object is no longer being accessed, and only then physically reclaims the memory used. And so it is on POSIX file systems: the file system keeps track of when the file on disk is no longer being accessed, and only then physically reclaims the blocks being used. Until then, deleting the file merely unlinks the file name from the blocks on disk, in the same way that del y merely unlinks the name y from the object 42. Opening files for exclusive read *by default* is a pointless and silly limitation. It#39;s also unsafe: if a process opens a file for exclusive read, and then dies, *no other process* can close that file. Oh come on. Are you actually going to use errors or unintended consequences, or even Acts of God to defend your argument? Features have to be judged by their actual consequences, not some unrealistic sense of theoretical purity. The actual consequences of mandatory exclusive file locking is, *it sucks*. Windows users are used to having to reboot their server every few days because something is broken, so they might not mind rebooting it because some file is locked in a mandatory open state and not even the operating system can unlock it. But for those with proper operating systems who expect months of uninterrupted service, mandatory locking is a problem to be avoided, not a feature. Okay. Okay. I suppose IF the car spontaneously combusted THEN the passengers would be wise to jump out, leaving the vehicle to the whims of inertia. In this analogy, is the car the file name, the inode, or the directory? Are the passengers the file name(s), or the file contents, or the inode? Is the driver meant to be the file system? If I have a hard link to the file, does that mean the passengers are in two cars at once, or two lots of passengers in the same car? One neat trick is to open a file, then delete it from disk while it is still open. So long as your process is still running, you can write to this ghost file, as normal, but no other process can (easily) see it. And when your process ends, the file contents is

help needed with subprocess, pipes and parameters

pass a bunch of different parameters into it, and use it as a batch over a
bunch of different papers.

My attempts run fine, create destination folders ok and prints done but don't
actually seem to process the file. Is there some way to get subprocess to
output the command it's generating so I can see what I'm doing wrong, rather
than just the output of the command?
How can I chekc that kate's opening the pipe left from bob?Bob may take
some time to execute, will that matter?

katePath = C:\\Programs\\kate\\kate.exe

Mocked object returning another Mocked object
Greetings Fellow Group, I'd need your help to fix some issues I have with my unitary tests. I'm trying to bring them to the next level by Mocking equipments controlled by my application. Despite me reading http://www.voidspace.org.uk/python/mock/index.html I cannot figure out how to do the following : I have an App object with the 'target' attribute. This target is controlling a piece of hardware. The hardware itself holds a software, hence the target object having an 'api' attribute. I hope I make sense. So basically I'd like self.target.api.anyMethod() to return a Mocked object (Mocking an Api object response). ** Question ** I do I make *all* method calls return a specifik Mock? target = Mock() result = target.api.start() # I'd like result to be a Mock I defined with the 'returnCode' attribute print result.returnCode 1 But I would like to do it for any method of api (the list is huge, setting each of them is not an option I think) so that in the end, result = target.api.start() result = target.api.stop() result = target.api.reset() result = target.api.loadSw() return all the same Mock object (with 'returnCode') Any idea ?

As I understand it, the goal is to write the api object so that you can call any function on it... I'd like result to be a Mock I defined with the 'returnCode' attribute print result.returnCode 1 ...and every function should just return the same return code. Right? But I would like to do it for any method of api (the list is huge, setting each of them is not an option I think) so that in the end, result = target.api.start() result = target.api.stop() result = target.api.reset() result = target.api.loadSw() return all the same Mock object (with 'returnCode') There are two options I could think of: 1. Intercept attribute lookup From the top of my head, the syntax is something like this: class TargetMock(object): def __getattr__(self, name): def default_result(*vargs, **kwargs): return ReturnCode(1) return default_result This just ignores the name and returns a function returning the mock return code. I think you get the idea. 2. Intercept individual lookups class TargetMock(object): def _default(self, *vargs, **kwargs): return ReturnCode(1) start = _default stop = _default reset = _default loadSW = _default Yes, this ignores your claim that the list of functions is too big to add every function individually. I'd just add them on demand when a test accesses a function that isn't there yet. The advantage is that it shows clearly which of the functions are just stubs if you actually implement a few of them differently. If the list functions is really that huge but you have a class (the real driver class) that defines this API, then you could extract this list programmatically. That way, you could also ensure that your mock API doesn't provide functions not supported by the original. Good luck! Uli -- http://mail.python.org/mailman/listinfo/python-list

Initial nose experience
I've been using unittest for many years, but have steadfastly (perhaps stubbornly) avoided newfangled improvements like nose. I finally decided to take a serious look at nose. There were a few pain points I had to work through to get our existing collection of tests to run under nose. I figured I'd share them for the benefit of others who may be going through the same process. First nose won't import executable files, at least not by default. All of our test files are executable, with a #!/usr/bin/env python line at the top, and a if __name__ == '__main__' block, which does some setup and invokes unittest.main(), at the bottom. Going to the top of our source tree and typing nosetests was an uninspiring experience: $ nosetests -- Ran 0 tests in 0.001s OK The fix is either make them non-executable, or do nosetests --exe. Next up was the the setup in the if __name__ == '__main__' block wasn't running. The solution here is to move all the setup to setUpModule(), where it belongs. SetUpModule() is new in Python 2.7 but it turns out it's trivial to drop that version into older systems (http://pypi.python.org/pypi/unittest2). We found a bunch of tests which require some specific setup before they could run (most blatantly, some selenium tests which depend on X11). When we were running tests semi-manually, that was not a big deal. With nose's find them all and run them strategy, this fails. The obvious fix is that every test needs to either set up the right environment, or be protected with the appropriate @skip decorator so it doesn't run if the environment isn't good. Lastly, nose, by default, doesn't say much. When things go wrong and you have no clue what's happening, --verbose and --debug are your friends. -- http://mail.python.org/mailman/listinfo/python-list

To come back to the OPs question. Variables can be assigned. Or they can be bound. [C++ programmers will be familiar with the difference between initialization and assignment] List comprehensions are defined in terms of assignment to the local variable rather than binding. Hence the issue. Below are two functions that simulate mapping (lambda x: x**i) where the i's come from some given list def binding_version(lst): if not lst: return [] i = lst[0] return [(lambda x: x ** i)] + binding_version(lst[1:]) def assign_version(lst): ret = [] for i in lst: ret.append(lambda x: x**i) return ret -- fs= binding_version([0,1,2]) fs[0](2) 1 fs[1](2) 2 fs[2](2) 4 fs= assign_version([0,1,2]) fs[0](2) 4 fs[1](2) 4 fs[2](2) 4 -- http://mail.python.org/mailman/listinfo/python-list

In development, your script is your execution unit, so you let the interpreter print out your tracebacks. In production, there will usually be one, maybe two subunits (for instance, a TCP-based server might have the socket connection as an execution unit, and possibly a command parser inside that), and at the top of that subunit, you have a broad exception handler that resets that one unit (goes back and accepts another client, or waits for another command).

On a Posix system, it's entirely normal to unlink() a temp file first thing after you've created it. The expectation is that the file will continue to exists, and be writeable, until you close it. In fact, there's a function in the standard library named tempfile.TemporaryFile that does exactly that: create a file and unlink it immediately. This function would be useless if you couldn't write to your temporary file. It's possible to create a temporary file even in Windows. -- http://mail.python.org/mailman/listinfo/python-list

Re: code review
From now on, for each operator I would have to remember wether it
is a supposedly comparison operator or not.
I believe the following rule is true: if a op b is True or False raises,
then op is a potentially chained comparison operation. They are (not)
equal (and (not) is), the 4 order comparisons, and (not) in. 'in' should
be the only surprise and most confusing.
1 3 in {3,4}
True
3 in {3,4} {4}
False
'and' and 'or' are not included because they do not always return a
bool, and indeed, they are not binary operators in the usual sense
because of short-circuiting.

howto do a robust simple cross platform beep
Hi, I just want to use a beep command that works cross platform. I tried the simplest approach (just printing the BEL character '\a' chr(7) to the console. This fails on my Ubuntu 12.04 host, as the pcspkr is in the list of the blacklisted kernel modules. I found another snippet trying to push a sine wave directly to /dev/audio but I don't have write permissions to /dev/audio. Other solutions seem to suggest to play a wav file, but of course first I had to write code creating me a wav file. How do others handle simple beeps? I just want to use them as alert, when certain events occur within a very long running non GUI application. Thanks for any info. What I do at the moment is: For Windows I use winsound.Beep For Linux I create some raw data and pipe it into sox's 'play' command.

For an inexperienced system administrator, this may appear mysterious. The solution is to us lsof to identify the unlinked file, which gives you the process id of the application, which you can then kill. As soon as you do that, the space is freed up again.

Re: lambda in list comprehension acting funny
On Jul 13, 10:53 pm, Hans Mulder han...@xs4all.nl wrote: If you add `global VERBOSE` to `caller`, then there is only one variable named `VERBOSE` and what `function` does, depends on the most recent assignment to that variable. If you remove your `global VERBOSE`, then there are two variables by that name, one global and one local to `caller`. In that case, there is the question of which one `function` will use. Good point. See below. The function `function` refers to a variable `VERBOSE` that isn't local. In some programming langauages, the interpreter would then scan the call stack at run-time, looking for a scope where that name is defined. It would find the local one in `caller`. This is known as dynamic binding. Other interpreters use the `VERBOSE` that was in scope at the point in the program text where `function` was defined. In this case, that would be the global one. This is called lexical binding. Some programming languages allow you to indicate on a per- variable basis whether you want dynamic or lexical binding. Python is firmly in the lexical camp. Dynamic binding is not available in Python, and never will be. Thats a good intention. The question is whether it is uniformly realized. Consider the following def foo(x): i = 100 if x: j = [i for i in range(10)] return i else: return i In python 2 two different 'i's could be returned. In python3 only one i can be returned. One could call it dynamic binding. Evidently Guido thinks it a bug which is why he changed it. The leakage of i in the OPs question is the same kind of bug. tl;dr version: This is 2012.

In python 2 two different 'i's could be returned. In python3 only one i can be returned. One could call it dynamic binding. One could also call it a tractor, but it isn't either of those things. The difference is whether or not list comprehensions create their own scope. In Python 2, they don't; in Python 3, they do. Personally I don't have an opinion as to which is better, but in neither case does this have any thing to do with lexical versus dynamic binding. Evidently Guido thinks it a bug which is why he changed it. It was a case that either list comps be changed to *not* expose their loop variable, or generator expressions be changed *to* expose their loop variable. The Python 2 situation where list comps and gen expressions have opposite behaviour was unfortunate. The leakage of i in the OPs question is the same kind of bug. Not at all. The OP was *deliberately* creating a closure using i -- under those circumstances, it would be a bug if i *didn't* leak. The OP's gotcha was: 1) he expected the closure to use early binding, where i in each function was bound to the value of i in the enclosing scope at the moment the function was defined; 2) but Python actually uses late binding for closures, where the value of i in each function is set to the value of i in the enclosing scope when the function is called. As far as I can tell, Python always uses late binding for scopes; the only time it does early binding is for default values of function parameters. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

[OT] Simulation Results Managment
Hi, This is a general question, loosely related to python since it will be the implementation language. I would like some suggestions as to manage simulation results data from my ASIC design. For my design, - I have a number of simulations testcases (TEST_XX_YY_ZZ), and within each of these test cases we have: - a number of properties (P_AA_BB_CC) - For each property, the following information is given - Property name (P_NAME) - Number of times it was checked (within the testcase) N_CHECKED - Number of times if failed (within the testcase) N_FAILED - A simulation runs a testcase with a set of parameters. - Simple example, SLOW_CLOCK, FAST_CLOCK, etc - For the design, I will run regression every night (at least), so I will have results from multiple timestamps We have 1000 TESTCASES, and 1000 PROPERTIES. At the moment, I have a script that extracts property information from simulation logfile, and provides single PASS/FAIL and all logfiles stored in a directory structure with timestamps/testnames and other parameters embedded in paths I would like to be easily look at (visualize) the data and answer the questions - When did this property last fail, and how many times was it checked - Is this property checked in this test case. Initial question: How to organize the data within python? For a single testcase, I could use a dict. Key P_NAME, data in N_CHECKED, N_FAILED I then have to store multiple instances of testcase based on date (and simulation parameters. Any comments, suggestions?

[issue15307] Patch for --symlink support in pyvenv with framework python
Ned Deily n...@acm.org added the comment: Fixing sys.executable to point to the stub launcher instead of the interpreter in the fw will also fix other unrelated issues, like making python3-32 work properly in 64-/32-bit builds for IDLE and for tests that spawn interpreters in subprocesses. Today, while the main process is 32-bit, the interpreters in subprocesses are 64-bit. I did a little clean up and fixed up the documentation somewhat; see the revised patch. But building a stock installer and running the tests showed two issues: 1) test_osx_env fails at line 28, checking PYTHONEXECUTABLE 2) when running the tests within a venv, test_venv now fails at line 95; sys.baseprefix != sys.prefix. This did not fail previously Also, I saw another test failure when building and running with a test framework environment that included a relative link. It appeared that _NSGetExecutablePath in pythonw.c returned an unnormalized path: sys.executable '/py/dev/default/b10.7_t10.7_x4.3_cclang_d/fw/./root/bin/python3.3' which caused a test_venv failure. I probably won't have time to look at this again for a few days. -- Added file: http://bugs.python.org/file26373/venv-symlinks-v4.txt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15307 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Can you tell me what other platforms they are available on? And/or suggest some alternate language? http://en.wikipedia.org/wiki/Xattr has a list. The question what’s most user friendly. The best way for the user would be your text. However we’ll have to dig through the docs once we support xattr on more platforms. However as I see it, we’re deep down this path already anyway (http://docs.python.org/dev/library/os.html?highlight=xattr#linux-extended-attributes), so I guess we can keep your docs.

[issue15307] Patch for --symlink support in pyvenv with framework python
Ronald Oussoren ronaldousso...@mac.com added the comment: I removed the call to realpath from pythonw because resolving symlinks breaks the feature. Realpath also converts relative paths to absolute paths, and that probably explains the new failure you're having. I'll try to find a solution for this, possibly by calling realpath on dirname(argv[0]) instead of the whole path. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15307 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9458] xml.etree.ElementTree.ElementTree.write(): encoding handling problems
Serhiy Storchaka storch...@gmail.com added the comment: ElementTree write works with two kinds of output -- binary and text. The difference between them is only determined by encoding argument. If encoding is unicode, then output is text, else it is binary. There is no other way for filename or general file-like object to determine kind of output. If these are not explained in the documentation, then the documentation should be improved. The patch can cause data corruption because direct writing to underlying file by fileno conflicts with TextIOBase/BufferedIOBase internal buffering. And not every file-like object have fileno. With patch the behavior becomes less obvious and will lead to confusion. I don't see a behavior bug which should be fixed. Only one thing can be enhanced -- error diagnostic in some corner cases. When we can determines that file object is instance of RawIOBase or TextIOBase and it is conflicts with encoding argument value, it will be helpful for novices to raise a descriptive exception. This is of course not eliminate all causes for confusing. -- nosy: +storchaka ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9458 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15307] Patch for --symlink support in pyvenv with framework python
Ronald Oussoren ronaldousso...@mac.com added the comment: v5 adds test cases for sys.executable and calls realpath on dirname(argv[0]) in pythonw.c and also has the changes in Ned's v4. The test failure for test_venv is expected, the note in http://docs.python.org/dev/library/venv.html explains that sys.base_prefix and sys.base_exec_prefix point to the non-venv Python installation which was used to create the venv. The test fails because it assumes that sys.base_prefix of the created venv is same as sys.prefix of the running python, which is not true when you create a venv in a venv. In particular line 95 of test_venv explicitly tests that sys.prefix == sys.base_prefix, which should fail when running the test within a virtual env. Tweaking the test suite to avoid that failure is beyond the scope of this issue. -- Added file: http://bugs.python.org/file26375/venv-symlinks-v5.txt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15307 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
