[issue24872] Add /NODEFAULTLIB:MSVCRT to _msvccompiler
Christoph Gohlke added the comment: FWIW, I rebuilt static libraries for zlib, jbig, jpeg, openjpeg, tiff, webp, lcms, and freetype with /MT flag (a tedious task) and was able to build matplotlib and Pillow using Python 3.5.0rc1. As expected there is no dependency on the vcruntime DLL. Even if everything is built with /MT and using UCRT, some extensions will still depend on version specific Visual C runtime DLLs, e.g. OpenMP, requiring users or distributors to install/bundle the VC runtime package. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24872 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Serhiy Storchaka added the comment:

that fully consumed its input iterable is already space-inefficient.

An internal iterator is not pickled as iter(de), but as an iterator of the
list [a, b, c, d, e] with 3 items consumed. This list also saved as a
part of a cycle object state, but not as a copy, but as a reference.
There are two alternative patches. Both keep Raymonds optimization of cycle
iterating, but have advantages. cycle_reduce_2.patch makes __reduce__ faster
and more memory efficient than Raymonds variant. cycle_reduce_3.patch makes
unpickled cycle object so optimized as original.

The user's password will be encrypted on the server and nobody will be able to Most systems I know of don't store the password on the server in the first place. They store a one-way hash generated from the password (possibly using a randomly generated salt that is also saved with the hash -- that is, rather than just hash password into hashstring, they hash saltpassword into otherhash and prepend the salt - saltotherhash. When user comes to connect later, they match the user name in the password database, extract the salt from saltotherhash, attach it to the password given by the user, generate the hash, and see if it matches the rest of the saved hash). The hash value is only used for matching purposes, not for any subsequent processing -- it is not a cryptography key, nor is any cryptography key used to produce it. Thanks for the feedback. Actually the passwords on my webmail in 2000 to 2005 were not encrypted, but I agree with you that passwords should be always encrypted. read the user's mail except the user himself. Is it possible? When I had How do you intend to handle new inbound email? After all, the sender of the email sure won't know about any user encryption key -- that means you have to have the encryption key stored on your server associated with the recipient username, so that you can encrypt inbound email before putting it into the user's mailbox... Do you also intend to encrypt the header information or just the body of the message? A public key system MIGHT support that, in that the public key -- used to send to the recipient is only used to encrypt the data, and can be stored on your server (in the same username/password account file). The private (decryption) key would have to be stored on the user's computer and never provided to your server machine -- and you'd need some way to send individual encrypted messages to the user where they are decrypted on their computer, NOT ON the server. You'd also need to be able to identify which messages are new, read, deleted -- if the mailbox is encrypted, this likely means each message is a file within the mailbox, since you can't do things like mark and compress an MBOX (all mail is in one file with a special header marking the start of a message) file without corrupting the encryption stream. If, at anytime, the decryption key is on the server, you have lost the security you claim to be striving for -- as any court ordered system could just patch in a packet sniffer and wait for your user to connect, capture the password, and capture the decryption key if it is sent to the server to retrieve mail (though they don't even need it at that point -- they could just capture the decrypted contents being sent to the user... TLS/SSL sessions may alleviate that problem, but it does mean having certificates to initiate the TLS session keys). If the packets are TLS encrypted, they can require one to patch into the server at the point where the contents are converted back to plain text and capture the traffic. Of course, this now means the user has to carry around a keyring that can be accessed by any computer used to read the email (since the decryption key can not be on the server, if they read email from an android tablet they need to have the key installed on the tablet; they also need it on their desktop if they use it to access the server; on their phone if it has a browser, etc.). A Javascript client is probably going to be rather slow at decrypting the emails -- but you may not be able to install a compiled Java encryption package on all the clients out there (you'd have to have something for iOS, something for Android, for Linux, Macintosh, and Windows -- though the latter three might be able to use the same core Java code). We've taken care of inbound email. What were your plans for outgoing email? You can't encrypt that as it is going to other systems and other users who are not part of your server and don't expect to see encrypted stuff. You could perhaps store the already sent messages using the same public key, but you can't do that with in-work drafts stored on the server prior to being sent (at least, not without requiring them to pass from the server to the client for decryption and then back to the server in plain-text for delivery -- deleting the draft copy and saving an encrypted sent copy) I think ProtonMail https://protonmail.ch/ is doing something similar to what I want, so maybe I'll check what they are doing.

Here're a couple of interesting projects that I found on a google search that might relate to what you're trying to do: http://www.python-camelot.com/ http://kivy.org/ But like the other poster said, take some time to learn a new language, such as Python. Things can get complicated in a hurry, but if you have a solid understanding of the language, it's doable. Also it is helpful if you have a good working knowledge of SQL. SQL is useful when interacting with a variety of database engines such as MS SQL, or a freely available one like PostgreSQL. Then there are dozens of different database access libraries and abstractions you can choose from such as SQLAlchemy. And for creating a GUI there are several different toolkits. As for the future of DOS, existing DOS programs including your DBASE-5 apps should continue running indefinitely with the wonderful DOSBox program: http://www.dosbox.com/.

Terry J. Reedy added the comment:
3.5 is the same as 3.6 in that now both help(help) and help('help') show the
not terribly helpful Help on _Helper in module site object: Buried in the
text is
| Calling help() at the Python prompt starts an interactive help session.
| Calling help(thing) prints help for the python object 'thing'.
As before, I think the _Helpter stuff should be eliminated and
explanation added for help('topic') and a description of what 'topic's are
specially recognized.
There has been this improvement
help('jslfjslfdjlskfj') # 3.4
no Python documentation found for 'jslfjslfdjlskfj'
help('jsflksjflkjsl') # 3.5
No Python documentation found for 'jsflksjflkjsl'.
Use help() to get the interactive help utility.
Use help(str) for help on the str class.
but the latter omits decription of what 'topic' will give special output. By
experiment, keywords (help('if')), builtins, and unimported modules
(help('itertools')) works.
Yes, 3.4 can be patched.

who use this api use IDE's and want the type hinting. So, options I
can think of are to create a load of classes and returning instances
of them, return named tuples or even terser would be to return
something like:
def api_method(foo, bar):
produces two return values, x and y.
...
return type('MyResult', (), {'__slots__': [], 'some_field': x,
'another_field': y})()
The last option humorously returns readonly fields.
However, the latter two don't help much for type hinting unless
someone knows something I don't about doc strings? As a Python user,
what is preferred?
Thanks,
jlc

[issue24879] Pydoc to list data descriptors in _fields order if it exists
New submission from Raymond Hettinger:
Currently, help() lists out data descriptors in alphabetical order. This is
fine in the general case, however if the fields are parts of a named tuple, it
is more sensible to list them in the order found in the tuple.
The presence of a named tuple can be detected by the presence of a _fields
attribute that is a list of strings. That strings can be used as a primary
sort key before an alphabetical sort of anything not listed in _fields.
Person = namedtuple('Person', ['nickname', 'firstname', 'age'])
help(Person)
Help on class Person in module __main__:
class Person(builtins.tuple)
| Person(nickname, firstname, age)
|
...
|

| __new__(_cls, nickname, firstname, age)

RPI.GPIO Help
Hello, all. I am hoping some people here are familiar with the RPi.GPIO
python module for the Raspberry Pi.
Very new to Python and electronics. Not to computing in general though.
I posted for help about accepting key presses and then discovered that
wiring up buttons directly to the Pi was 1/50th as difficult as I thought
it would be so I am going a different route than keyboard emulation and
needing GUI toolkits, etc.
However, I am getting error messages with RPi.GPIO.
I have three buttons, Red, Yellow and Blue in colour, attached to the
Pi. The eventual goal is to have pressing one button result in changing
the colour of an LED lightstrip to that colour and the Pi record how long
the strip spent as each colour.
For development purposes I have the controls near me and my desktop
computer, and the Pi networked to this computer. For now I have each
button press result in a print statement. When I get this working I will
replace the print statements with the code to change colours on the LED
strip using the Blinkstick module.
This is the basic test code.

no module named kivy import error in ubuntu 14.04
Hi I am new to linux. I tried various things in attempt to install kivy. I installed python 2.7.10 (I think python3 was already installed in ubuntu 14.04). Then i downloaded kivy from https://pypi.python.org/packages/source/K/Kivy/Kivy-1.9.0.tar.gz, extracted it and tried to execute python setup.py inside the kivy folder. But it showed the error no module named cython. Then I tried installing cython, it installed successfully but the command python setup.py still gave the error no module named cython. Finally I installed kivy using instructions on this video: https://www.youtube.com/watch?v=mypVFCIIZtw. Now when i try to run the following commands: $ cd path to kivy-examples (I used the actual path, i.e., /usr/share/kivy-examples) $ cd demo/touchtracer $ python main.py I am still getting the error:ImportError: No module named kivy. Any help will be highly appreciated. Thanks. -- https://mail.python.org/mailman/listinfo/python-list

distutils error ?
I tried building the spammodule.c example described in the documentation

generates a link error:

without errors but generated a system error when _spam was imported.

Hello, all. I am hoping some people here are familiar with the RPi.GPIO
python module for the Raspberry Pi.
Very new to Python and electronics. Not to computing in general though.
I posted for help about accepting key presses and then discovered that
wiring up buttons directly to the Pi was 1/50th as difficult as I thought
it would be so I am going a different route than keyboard emulation and
needing GUI toolkits, etc.
However, I am getting error messages with RPi.GPIO.
I have three buttons, Red, Yellow and Blue in colour, attached to the
Pi. The eventual goal is to have pressing one button result in changing
the colour of an LED lightstrip to that colour and the Pi record how long
the strip spent as each colour.
For development purposes I have the controls near me and my desktop
computer, and the Pi networked to this computer. For now I have each
button press result in a print statement. When I get this working I will
replace the print statements with the code to change colours on the LED
strip using the Blinkstick module.
This is the basic test code.

I'm looking at this:
http://sourceforge.net/p/raspberry-gpio-python/wiki/Inputs/
As far as I can tell, the 'add_event_detect' method adds a callback.
However, you have it in a loop, so you're trying to add more than one
callback (actually, the same one more than once!), which it doesn't
like.
You should add the callbacks only once and then have some kind of sleep
or do-nothing loop, perhaps waiting for the signal to quit (I don't
have a Raspberry Pi, so I don't know what the usual practice is).

If the dependency isn't there, it'll be fine. Do you think it'll be worth having a check box in the installer to get the full runtime? Bearing in mind that most won't need it and many won't be able to install it?

I'd rather return an object with properties, however all the guys

I believe the above gives you both: custom class for type hinting and

Thanks. But I note that those are all for very old, EoL'd versions of Fedora. I manually installed cython with pip, but then the kivy install failed with some C errors. At the top of it's multi-thousand line log output was a warning that it requires cython-0.21.2. Pip had installed cython-0.23. I installed cython-0.21.2 (since I do not use cython for anything else and noting that pip did not bother to inform me it was overwriting an existing install) and then pip installed kivy without error. However there were a number of warning message about missing somethings (libs or python packages, was not clear to me). So I eventually found the kivy docs on their website where they list prerequisite packages for installing kivy on ubuntu. I'll translate those to hopefully the equivalent fedora package names, install them, reinstall kivy, and get a working kivy install. The point here that all the above is a LONG way from what was was posted here: just type 'pip install kivy' and pip will take care of everything.
