Marcio, The existence of forum site / mailing list does not guarantee your problem will be solved. The bitbucket.org doesn’t offer mailing list feature, however you can subscribe to any changes happening by following me or concrete project there. The specific issues can be tracked down to commit via issues list. What relates to mailing list… I have sent request to google groups to allow dot in name, however there was no reply yet. I suppose that might take a week to hear something back from them. Anyway, should you have any specific questions please use this mailing list or contact me directly.

There have been some issues with running Python on OSX, so you'd want to make sure you're running the very latest; for instance, 3.3.4 fixed some issues with 10.9 Mavericks. Generally, I'd say you'll do reasonably well on either platform, as long as you're happy with the editor and related tools; but personally, I love my Linux for development. I use Debian (Ubuntu is closely related to Debian), with Xfce, SciTE, and roughly ten thousand terminal windows - that's my IDE. SciTE is available for a Mac, and there are plenty of other excellent text editors as well, so you shouldn't have any trouble on that score. Your text editor is probably more important to your productivity than your OS is. Whether you're on Windows, Mac OS, or Linux, or something more obscure like OS/2, you can run your scripts just fine (OS/2 isn't an officially supported Python platform, but I have a third-party build that works fine for me); the important part is getting code from your brain through your fingers into the computer, and a good editor can help hugely with that. You'll hear advocates for vi/vim, emacs, and myriad others, but ultimately, just grab one that looks good and get to know it :) Personally, I'd recommend going Linux, for the openness; among other benefits, it's generally easier to build C stuff from source on Linux than on pretty much any other platform. But you should be able to use your preferred Mac just fine, and learning something new is a cost that's hard to justify. Just do be sure (and yes, I'm reiterating this) that you're on the very latest Python you can get. At the moment, that's 3.3.4, but soon there'll be a 3.4 release.

Please advise It's not clear what you mean here; I'll guess that by iterations you mean changes by database you mean the db or ndb datastore and by info you mean data stored in the datastore. Apologies if this isn't so. Appengine doesn't document any migration utilities to handle changes in your datastore schema, so you need to manage the effects of such changes yourself. To ensure that you do not lose data when changing your model code, avoid making destructive changes to your models, i.e. - don't delete properties from a model - don't rename properties on a model If you must make these changes for some reason, you'll need to migrate the data somehow. In my experience with Appengine, data is not actaully lost if you make destructive changes to your models, it becomes inaccessible becuae the property names it was stored under no longer exist on the model. In theory you could access the data by adding the proprties back to the model or (maybe) by loading a different model definition in the remote shell, but this is not something that you would want to rely on in a production environment. tl,dr: it's ok to add new properties to you models, but don't remove or rename properties.

That's the exact line of thinking that leads to problems. You are not placing a number at the address xyz, you are pointing the name xyz to the number 3. That number still exists elsewhere. xyz = 3 abc = xyz Does this copy the 3 from xyz into abc? In C, it would. Those variables might not exist anywhere, but they must, by definition, be storing the integer 3. And that integer has been copied. But in Python, no it does not. It doesn't *copy* anything. And if you fiddle with the integer 3 in some way, making it different, it'll be different whether you look at xyz or abc, because they're the same 3. You can't see that with integers because Python's int is immutable, but this is where the confusion about mutable vs immutable objects comes from. Immutable objects behave *sufficiently similarly* to the C/Pascal model that it's possible to think Python works the same way, but it doesn't. The nearest C equivalent to what I'm talking about is pointers. (CPython objects are basically used with pointers anyway. When you get back an object reference from a CPython API function, you get a pointer, optionally with the responsibility for one of its references.) This is broadly how Python objects work: /* Python strings are immutable, so the equivalent would be a list. */ /* I'm using a string because C doesn't have a list type. */ char *xyz = strcpy(malloc(20),Hello, world!); char *abc = xyz; xyz[1] = 'a'; printf(abc has: %s\n, abc); That'll show that abc has Hallo, world!, even though it was through xyz that the change was made. The thing that is that string is the puddle of bytes on the heap (allocated with the malloc(20) up above). The name just has a reference to that. Creating another reference to the same object doesn't change anything. ChrisA -- https://mail.python.org/mailman/listinfo/python-list

The address could be a symbol, too. The Python statement xyz = 3 places a number in the address xyz. It doesn't matter whether addresses are numeric or symbolic, Python does not use that model for variables. Consider this example. There are a few steps, so let's go through them. First we prove that so-called address abc and xyz are distinct. If they were the same address, then they would logically have to contain the same value, but that is not the case: abc = 23 xyz = 42 assert abc != xyz This proves that the two addresses are different. Now we prove that they are the same address: abc = xyz = [] xyz.append(42) assert abc == [42] If they were different, then modifying the object at xyz cannot modify the object at abc. So we have a contradiction: addresses abc and xyz are both the same address, and different addresses. There is a way to wiggle out of the contradiction: accept that the addresses are distinct, but claim that a single object can be in two different locations at once. But if we make that argument, we are stretching the metaphor of location quite considerably. Absent time- travel, objects cannot be in two locations at once. Claiming that they can be requires stretching the metaphor of location past breaking point. Self-confession time: some years ago, I used to make exactly that argument. I used to argue that the right way to visualise Python's variable model was to consider that objects were stored in variables in exactly the way you are suggesting. I didn't describe them as symbolic addresses, but otherwise the model was the same. In order to make the model work, I argued that objects could be in more than one place at once, including *inside* itself: L = [] L.append(L) and explicitly argued that this didn't matter. After all, if I can watch Doctor Who and accept the concept of his TARDIS materialising inside itself, I can understand the idea of a list being inside itself. That was before I really grasped the difference between the name binding and fixed location variable models. While I'm still fond of the concept of a box being inside itself, I've come to understand that having to stretch the metaphor of location so far simply indicates that the metaphor does not work with Python's semantics. Python's actual behaviour is not a good fit for the variables are locations model, not even if you think of locations in the abstract with symbolic names rather the numeric addresses. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

[ANN] pyOpenSSL 0.14
Greetings fellow Pythoneers, I'm happy to announce that pyOpenSSL 0.14 is now available. pyOpenSSL is a set of Python bindings for OpenSSL. It includes some low-level cryptography APIs but is primarily focused on providing an API for using the TLS protocol from Python. Check out the PyPI page (https://pypi.python.org/pypi/pyOpenSSL) for downloads. This release of pyOpenSSL adds: * Support for TLSv1.1 and TLSv1.2 * First-class support for PyPy * New flags, such as MODE_RELEASE_BUFFERS and OP_NO_COMPRESSION * Some APIs to access to the SSL session cache * A variety of bug fixes for error handling cases Additionally, there are three major changes to the project: First, the documentation has been converted from LaTeX (CPython's previous documentation system) to Sphinx (CPython's new documentation system ;). You can find the new documentation on the PyPI documentation site (https://pythonhosted.org/pyOpenSSL/) or https://pyopenssl.readthedocs.org/). Second, pyOpenSSL is no longer implemented in C as a collection of extension modules using the Python/C API. Instead, pyOpenSSL is now a pure-Python project with a dependency on a new project, cryptography (https://github.com/pyca/cryptography), which provides (among other things) a cffi-based interface to OpenSSL. This change means that pyOpenSSL development is now more accessible to Python programmers with little or no experience with C. This is also how pyOpenSSL is now able to support PyPy. Finally, the project's code hosting has moved from Launchpad to Github. Many branches remain only on Launchpad along with their associated bug reports. Over the coming releases I hope that the fixes and features in these branches will be ported to Python and incorporated into the pyOpenSSL master development branch. Bug tracking has been disabled on Launchpad so that the amount of useful information hosted there can gradually dwindle to nothing. Please use Github (https://github.com/pyca/pyopenssl) for further development and bug reporting. Thanks and enjoy, Jean-Paul -- https://mail.python.org/mailman/listinfo/python-list

I'm not sure you can depend on that sort of pattern of memory usage. In any case, you'd need some way to pretend that every integer is really an object, so you'd need to define id(), the 'is' operator, and everything else that can work with objects, to ensure that they correctly handle this. It would be a reasonable performance improvement to use native integers for the small ones (where small integers might still be fairly large by human standards), but unlike in languages like Pike (which does something like what you're saying), Python has a concept of object identity which can't be broken. (Pike's integers simply _are_, they aren't considered separate objects. You can't test them for identity. Its strings, also, simply are, although since Pike strings are guaranteed to be interned, their values and identities really are the same. To Pike, it's only more complex types that need to distinguish value from identity.) So this optimization, which certainly does make sense on the face of it, would potentially make a mess of things elsewhere. I'm sure PyPy optimizes small integers somewhat, though.

The language spec is based on duck typing everything as an object with a class and attributes. Revised code would have to either turn the reference int into a real object on every access (which would be tremendously inefficient), or code special case treatment of reference ints into *every* piece code that might act on ints (which is all over the interpreter) so as to simulate the int object behavior. id(someint) is the least of the problems. Special-casing ints to store the value in the reference has been proposed and rejected.

Re: Can tuples be replaced with lists all the time?
On Sunday, February 23, 2014 12:06:13 PM UTC+8, Sam wrote: My understanding of Python tuples is that they are like immutable lists. If this is the cause, why can't we replace tuples with lists all the time (just don't reassign the lists)? Correct me if I am wrong. == OK, lets be serious about high-level programming lnguages. Python is a dynamical typed ( name binding mechnism implicitly), imperative language with the built in auto GC and the heap plus stack managements in the bundled scriptor. A tuple is treated immutable and a list is mutable in Python. I suggest one can read the introductions about Erlang which is a non-imperative high level language in the 5 to 6 th gen programming languages in back-end server applictions for the robustness and maintainence costs. Neverthless, Python is regarded as a programming firendly language when comparing with other high level languages. -- https://mail.python.org/mailman/listinfo/python-list
Re: Can global variable be passed into Python function?
Chris Angelico ros...@gmail.com: id() is (if I recall correctly) supposed to return an integer in the native range That restriction seems beyond the scope of the language definition. Still, it can be trivially provided for. In any case, you'd need some way to pretend that every integer is really an object, so you'd need to define id(), the 'is' operator, and everything else that can work with objects, to ensure that they correctly handle this. Trivial, I should say. It would be a reasonable performance improvement to use native integers for the small ones Maybe. Point is, whether it's done this way or that is irrelevant from the point of view of functional correctness. Whether an integer is an object or not has absolutely nothing to do with the implementation of the interpreter. And thus, Python variables are barely distinguishable from C variables.

It doesn't make any difference whatsoever for a Python programmer how this or that object type has been implemented under the hood. Hogwash. Int variables are not all variables.

Looking for someone who can build a 64-bit version of SpamBayes installer for Windows
SpamBayes development has been dormant for several years, however it still has a reasonably good following among the Outlook crowd. (I guess Microsoft has still not provided good spam filtering tools for Outlook?) Anyway, though all of SpamBayes is written in pure Python, there is still a small amount of glue code (Microsoft Visual C++-generated dialogs, I think) which is written in C++. As more and more Windows users have moved to 64-bit versions of Windows and Outlook, we've had more and more reports of failures. I think all that's necessary (speaking as someone who knows nothing about Windows) is for someone to build a 64-bit version of the SpamBayes installer for Windows. I don't know how hard that would be, but I presume that for someone with some experience in this area it probably wouldn't be difficult. The current SpamBayes code base should run with Python 2.7. Anybody available to help? Thanks, Skip Montanaro -- https://mail.python.org/mailman/listinfo/python-list

Anyway, we are discussing this to make it clear that the language definition is abstract. No. The language definition is concrete: it describes a concrete interface. You are confusing the interface with the implementation: the language definition is only abstract with regard to the implementation, which is free to vary, so long as the interface remains the same. Regardless of the implementation, Python code must behave in certain ways, and the reference implementation CPython defines the semantics of variable as name binding, not fixed locations. Can this by implemented using fixed locations? Of course it can, and is: the proof is that CPython's name binding variables are implemented in C, which uses fixed location variables. All compliant implementations are equally correct. It doesn't make any difference whatsoever for a Python programmer how this or that object type has been implemented under the hood. Performance can matter :-) But you are correct, as far as it goes. Where you are going wrong is by confusing the semantics of Python code with the underlying implementation of the Python virtual machine. -- Steven -- https://mail.python.org/mailman/listinfo/python-list

[RELEASED] Python 3.4.0 release candidate 2 is now available
On behalf of the Python development team, I'm delighted to announce the second and final release candidate of Python 3.4. This is a preview release, and its use is not recommended for production settings. Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Major new features and changes in the 3.4 release series include: * PEP 428, a pathlib module providing object-oriented filesystem paths * PEP 435, a standardized enum module * PEP 436, a build enhancement that will help generate introspection information for builtins * PEP 442, improved semantics for object finalization * PEP 443, adding single-dispatch generic functions to the standard library * PEP 445, a new C API for implementing custom memory allocators * PEP 446, changing file descriptors to not be inherited by default in subprocesses * PEP 450, a new statistics module * PEP 451, standardizing module metadata for Python's module import system * PEP 453, a bundled installer for the *pip* package manager * PEP 454, a new tracemalloc module for tracing Python memory allocations * PEP 456, a new hash algorithm for Python strings and binary data * PEP 3154, a new and improved protocol for pickled objects * PEP 3156, a new asyncio module, a new framework for asynchronous I/O Python 3.4 is now in feature freeze, meaning that no new features will be added. The final release is projected for mid-March 2014. The python.org web site has recently been updated to something completely new, and I'm having some difficulty updating it. For now I've made Python 3.4.0rc2 available on the legacy web site: http://legacy.python.org/download/releases/3.4.0/ Once I can update the new web site, Python 3.4.0rc2 will be available here: http://python.org/download/releases/ (I'm not sure what the final URL will be, but you'll see it listed on that page.) Please consider trying Python 3.4.0rc2 with your code and reporting any new issues you notice to: http://bugs.python.org/ Enjoy! -- Larry Hastings, Release Manager larry at hastings.org (on behalf of the entire python-dev team and 3.4's contributors) -- https://mail.python.org/mailman/listinfo/python-list

[issue20742] 2to3 zip fixer doesn't fix for loops.
New submission from David Jones:
Consider the following code:
for z in zip([1]):pass
2to3 does not convert the zip in this code to list(zip(...)); it does not
change this code at all.
That can be an (obscure) bug because the zip in Python 2 has different
semantics from the zip in Python 3.
The output of this program
from __future__ import print_function
S = []
def l(c):
for i in [0,1]:
S.append(c)
yield i
S.append(c.upper())
la = l('a')
lb = l('b')
for a,b in zip(la, lb):
S.append(#)
print(''.join(S))
is different in Python 2 and Python 3 (when converted with 2to3, which doesn't
change the program).
In Python 2 the output is:
ababA##
In Python 3 the output is:
ab#ab#A
Obviously this example is somewhat contrived, but I have a non-contrived
example involving decoding PNG images (if anyone is interested).

[issue20155] Regression test test_httpservers fails, hangs on Windows
Jeff Allen added the comment: Thanks for adding to the evidence here. As discussed above, disabling the security product (which is Bitdefender) on my PC didn't stop the problem for me, and I'm reluctant to uninstall. I narrowed it to the Windows Base Filtering Engine, but perhaps the behaviour of the BFE is extended by installing BD. If so, you could say this is not a Python problem, it is caused by BD normalising the HTTP. Or BD could say it is caused by expecting a defined result from abnormal HTTP. I took the view it were best fixed at our end. I found I could test the same thing (AFAICT), but modify the tests so they don't get interfered with. http://bugs.jython.org/issue2109 http://hg.python.org/jython/rev/6441fcfd940b Would a patch made from this be applicable to CPython? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20155 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20636] Better repr for tkinter widgets
Serhiy Storchaka added the comment: tkinter.Button object .3070343372.3066782348 Not knowing the internal of tkinter, this seems somewhat confusing. Is that an anonymous name/id? If the name parameter is not specified, repr(id(self)) is used. Here is a button with id() == 3066782348, its parent has id() == 3070343372 and its grandparent is root. str() for this button returns full name .3070343372.3066782348. tkinter.Button object .panel.b1 This already looks more useful. How is that determined? Why the first object is missing (i.e. .panel seems to be an attribute of a missing object)? Tk widgets are organized in hierarchical structure and names look similar to file system names. . is the root, .frame is a frame in the root, .frame.b1 is a button in frame .frame. Regarding the patch, are you sure that .__class__.__module__ is always available? I seem to remember that it might be missing in some cases, e.g. modules written in C (but I might be confusing it with something else like __file__). Yes, for example __module__ is absent in _tkinter.TkappType.

[issue20747] Charset.header_encode in email.charset doesn't take a maxlinelen argument and has inconsistent behavior with different encodings
New submission from Rik:
If you look at the `header_encode` method in the `Charset` class in
`email.charset`, you'll see that depending on the `header_encoding` that is set
on the `Charset` instance, it will either encode it using base64 or
quoted-printable (QP):
http://hg.python.org/cpython/file/3a1db0d2747e/Lib/email/charset.py#l351
However, QP always uses `maxlinelen=None` and base64 doesn't. This results in
the following behaviour:
- If you use base64 encoding and your header size is longer than the default
`maxlinelen`, it will be split over multiple lines.
- If you use QP encoding with the same header it doesn't get split over
multiple lines.
You can easily test it with this snippet:
from email.charset import Charset, BASE64, QP
header = (
'tejkstj tlkjes takldjf aseio neaoiflk asnfoieas nflkdan foeias '
'naskln ioeasn kldan flkansoie naslk dnaslk fndaslk fneoisaf '
'neklasn dfklasnf oiasenf lkadsn lkfanldk fas dfknaioe nas'
)
charset = Charset('utf-8')
charset.header_encoding = BASE64
print 'BASE64:'
print charset.header_encode(header)
charset.header_encoding = QP
print 'QP:'
print charset.header_encode(header)
Which will output:
BASE64:
=?utf-8?b?dGVqa3N0aiB0bGtqZXMgdGFrbGRqZiBhc2VpbyBuZWFvaWZsayBhc25mb2llYXMg?=
=?utf-8?b?bmZsa2RhbiBmb2VpYXMgbmFza2xuIGlvZWFzbiBrbGRhbiBmbGthbnNvaWUgbmFz?=
=?utf-8?b?bGsgZG5hc2xrIGZuZGFzbGsgZm5lb2lzYWYgbmVrbGFzbiBkZmtsYXNuZiBvaWFz?=
=?utf-8?b?ZW5mIGxrYWRzbiBsa2ZhbmxkayBmYXMgZGZrbmFpb2UgbmFz?=
QP:
=?utf-8?q?tejkstj_tlkjes_takldjf_aseio_neaoiflk_asnfoieas_nflkdan_foeias_naskln_ioeasn_kldan_flkansoie_naslk_dnaslk_fndaslk_fneoisaf_neklasn_dfklasnf_oiasenf_lkadsn_lkfanldk_fas_dfknaioe_nas?=
This is inconsistent behavior.
Aside from that, I think the `header_encode` method should accept an argument
`maxlinelen` that defaults to an appropriate value (probably 76), but which you
can overwrite on free will.
This is (I think) also necessary because the `Header` class in `email.header`
has a `maxlinelen` attribute that is used for the same purpose. Normally this
works fine, but when you specified a charset for your header, it uses the
`Charset` class and the `maxlinelen` is lost. This is happening here:
http://hg.python.org/cpython/file/3a1db0d2747e/Lib/email/header.py#l368
You see, the `_encode_chunks` takes the `maxlinelen` argument but doesn't pass
it on to the `header_encode` method of `charset` (which is a `Charset`
instance).
As such, you can see this issue in action with the following snippet:
from email.header import Header
maxlinelen = 999
print 'No charset:'
print Header(
u'asdfjk lasjdf sajdfl ajsdfaj sdlkfjas kfladjs flkajsdflk jsadklf
jadslkfj adslkfj asdlkjf lksadjfkldas jfkldasj fkadsj fladsjf kladsjfk
asdjfkldasasd kfaj kfladsj fkadsjf asdf ',
maxlinelen=maxlinelen
).encode()
print 'Charset with special characters:'
print Header(
u'attachment; filename=ajdsklfj klasdjfkl asdjfkl jadsfja sdflkads fad
fads adsf dasjfkl jadslkfj dlasf asd \u6211\u6211\u6211 jo \u6211\u6211 jo
\u6211\u6211',
charset='utf-8',
maxlinelen=999
).encode()
Which will output:
No charset:
asdfjk lasjdf sajdfl ajsdfaj sdlkfjas kfladjs flkajsdflk jsadklf jadslkfj
adslkfj asdlkjf lksadjfkldas jfkldasj fkadsj fladsjf kladsjfk asdjfkldasasd

[issue20748] 3.4rc2 MSI uninstallation leaves behind ensurepip _uninstall .pyc
New submission from Martin v. Löwis: The installer currently leaves behind a single pyc file, namely Lib\ensurepip\__pycache__\_uninstall.cpython-34.pyc I believe that the problem is that installer computes the list of files to be removed in the script generation phase, finding out what files match __pycache__\*.*. The _uninstall .pyc is not there yet. Then, during script execution, first pip uninstallation is run, creating the pyc file, then the (precomputed) list of files is removed. In rc1, this was not a problem because PIP removal happened in the UI phase (i.e. before script execution); this was changed to support elevated privileges in #20641. The simplest work-around could be to run pip uninstallation with -B. I just edited the MSI with orca, and that seems to work fine. If anybody can suggest how installer could be instructed to remove the .pyc regularly through the RemoveFiles action, I'd appreciate any help. -- messages: 212014 nosy: loewis priority: release blocker severity: normal status: open title: 3.4rc2 MSI uninstallation leaves behind ensurepip _uninstall .pyc ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I fail to see how two CDATA sections in one element are related to support for ]] inside CDATA.

[issue6143] IDLE - an extension to clear the shell window
Tal Einat added the comment: Terry, please do give Squeezer a try before making a decision! Squeezer may be slightly more complex than ClearWindow in concept and in code, but IMO it is simpler and more appropriate for use by a novice user. I'm attaching a screenshot to give a feeling of what working in the IDLE shell with Squeezer looks like. This screenshot was taken on Windows. Note that the second squeezed text is the very long Max recursion depth exception traceback, which I manually squeezed after it was printed. Now I'll try to make the case for Squeezer one last time... Nobody expects a Squeezer Inquisition! Amongst Squeezer's weaponry are such diverse elements as: 1. No fear! Squeezer automatically catches overly long outputs for users, so they need not fear crashing IDLE or losing their history just by printing something long accidentally. 2. No surprise! Squeezer requires no learning and is completely self-explanatory. It's an in-line button with a label of the form Squeezed text (13412 lines). Hovering over it with the mouse shows tooltip listing the various available interactions (expand, copy, preview). Don't want the text to be squeezed? Double-click and the button is replaced by the original text! 3. Ruthless efficiency! With Squeezer, IDLE will never slow down to a crawl again! (Well, unless you explicitly expand a very long output.) 4. Dashing red uniforms! Okay, not really, but it does look nice. Also, beware *the comfy chair*! Squeezer conveniently allows one to manually squeeze exception tracebacks and other outputs to clean up the shell history. This is available via the right-click context menu. Finally, I'll mention that ClearWindow forces a user to choose: delete your entire shell history, or keep it all. Squeezer allows a user to choose which parts to hide and which to keep, and nothing is ever lost since squeezed text can always be expanded again. That's it. If this doesn't convince people of the utility of Squeezer, I truly believe nothing else will. -- Added file: http://bugs.python.org/file34200/Squeezer Screenshot.PNG ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6143 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20646] 3.4 cherry-pick: 180e4b678003 select and kqueue round the timeout aways from zero
Gregory P. Smith added the comment: I don't see why this cannot wait until 3.4.1. True, rounding away from zero is desirable in these cases but it seems like this should be a non issue most of the time and any distro (ubuntu) that picks up 3.4.0 can apply this fix to their own python package if they ever find this causing an actual problem. It was never explained in the original #20320 why anything considers it sane to call a selector with a non-zero microscopic timeout in the first place and expect well defined behavior. IMNSHO desiring any timeout less than a millisecond is asking for trouble from a variety of OS APIs. -- nosy: +gregory.p.smith ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20646 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Martin v. Löwis added the comment: I fail to see the bug in Python. minidom is behaving correctly. The error is in xmlrunner, which does error_info = str(test_result.get_error_info()) failureText = xml_document.createCDATASection(error_info) This is incorrect - it would have to check that error_info does not contain ]] (since CDATA sections must not contain ]]). If it finds ]] in the error_info, it would have to create two CDATA sections, e.g. one up to and including ]], and the second one starting at (repeated if there is more than one occurrence of ]] in error_info. Alternatively, it should just create a text node, since writing a text node will properly escape all special characters in error_info. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue20714 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
