Access a class in another python script

[DBS]

Hello,

I'm using Python 3.5 and have two python scripts where one needs access to a 
class in the other script for authentication purposes.

The scripts runs through GitHub to poll for all pull requests and pull requests 
that meet a certain condition.

The call from the second script to the class and variables in the first script 
are working, but I'm getting prompted for credentials several times.

I wrapped the credentials in a class and created an object in the second script 
to access the class so that I would not be prompted for credentials in the 
second script.  I've include both scripts below.  

I'm still new to python, but I think it's how I'm calling the class or the 
import in the second script???

Thanks in advance for your time.

Speaking as (a) webmaster, a page that tells windows users how to 
have more than one Python version on your machine; how to use
virtualenv after you have multiple Python versions, and how
to find out which versions of Python you already have would have
significant value.

For this to be useful in Python, you would have to annotate Python's small 
object allocator to designate it as a malloc()-like function, no?

libevent-python

[chenc...@inhand.com.cn]

hi:
   I use libevent-python package currently. I read the file 
eventmodule.c, but I can not understand the function:


  static EventObject *EventBase_CreateEvent(EventBaseObject *self, 
PyObject *args, PyObject *kwargs)

 {
   EventObject *newEvent = NULL;

   newEvent = (EventObject *)Event_New(_Type,NULL,NULL);

   if (Event_Init(newEvent, args, kwargs) < 0){
 return NULL;
   }

   if (PyObject_CallMethod((PyObject *)newEvent, "setEventBase", "O", 
self) == NULL){

 return NULL;
   }

   return newEvent;
 }

 So, I can not know the param "EventBaseObject *self" is what?  And I 
read the examples/echo_server.py file, I read the follow source:

   class BaseConnection(object):
bufferSize = 2**16
def __init__(self, sock, addr, server):
self.sock = sock
self.addr = addr
self.server = server
self.sock.setblocking(False)
self.buf = []
self.readEvent = libevent.createEvent(
self.sock,libevent.EV_READ|libevent.EV_PERSIST, self._doRead)
self.writeEvent = libevent.createEvent(
self.sock,libevent.EV_WRITE, self._doWrite)
self.startReading()
 So, I can not see pass the self parameter. Is anybody know this?

[issue25300] Enable Intel MPX (Memory protection Extensions) feature

[STINNER Victor]

STINNER Victor added the comment:

FYI In the discussion of the PEP 445 "Add new APIs to customize Python
memory allocators" it was proposed to add runtime option to choose the
memory allocator. At least for debug purpose, it would help to be able
to use malloc() for *all* Python memory allocations. Would it help to
find more bugs with MPX?

It's not possible to disable our fast allocator for small objects,
disabling it has a high cost on performances (Python would be much
slower).

[issue25341] File mode wb+ appears as rb+

[Mark Williams]

New submission from Mark Williams:

There is at least one mode in which a file can be opened that cannot be 
represented in its mode attribute: wb+.  This mode instead appears as 'rb+' in 
the mode attribute:

Python 3.5.0 (default, Oct  3 2015, 10:40:38)
[GCC 4.2.1 Compatible FreeBSD Clang 3.4.1 (tags/RELEASE_34/dot1-final 208032)] 
on freebsd10
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> if os.path.exists('some_file'): os.unlink('some_file')
...
>>> with open('some_file', 'r+b') as f: print(f.mode)
...
Traceback (most recent call last):
  File "", line 1, in 
FileNotFoundError: [Errno 2] No such file or directory: 'some_file'
>>> with open('some_file', 'w+b') as f: print(f.mode)
...
rb+
>>> with open('some_file', 'r+b') as f: print(f.mode)
rb+


This means code that interacts with file objects cannot trust the mode of 
binary files.  For example, you can't use tempfile.TemporaryFile (the mode 
argument of which defaults to 'wb+') and GzipFile:


>>> import gzip
>>> from tempfile import TemporaryFile
>>> with TemporaryFile() as f:
... gzip.GzipFile(fileobj=f).write(b'test')
...
Traceback (most recent call last):
  File "", line 2, in 
  File "/usr/local/lib/python3.5/gzip.py", line 249, in write
raise OSError(errno.EBADF, "write() on read-only GzipFile object")
OSError: [Errno 9] write() on read-only GzipFile object


This occurs because without a mode argument passed to its initializer, GzipFile 
checks that the fp object's mode starts with 'w', 'a', or 'x'.

For the sake of completeness/searchability: w+ and r+ are different modes, so 
rb+ and wb+ must be different modes.  Per 
https://docs.python.org/3/library/functions.html#open :

"""
For binary read-write access, the mode 'w+b' opens and truncates the file to 0 
bytes. 'r+b' opens the file without truncation.
"""


I haven't been able to test this on Windows, but I expect precisely the same 
behavior given my understanding of the relevant source.

_io_FileIO___init___impl in _io/fileio.c does the right thing and includes 
O_CREAT and O_TRUNC in the open(2) flags upon seeing 'w' in the mode:

https://hg.python.org/cpython/file/3.5/Modules/_io/fileio.c#l324

this ensures correct interaction with the file system.  But it also sets 
self->readable and self->writable upon seeing '+' in the mode:

https://hg.python.org/cpython/file/3.5/Modules/_io/fileio.c#l341

The open flags are not retained.  Consequently, when the mode attribute is 
accessed and the get_mode calls the mode_string function, the instance has 
insufficient information to differentiate between 'rb+' and 'wb+':

https://hg.python.org/cpython/file/3.5/Modules/_io/fileio.c#l1043

If the FileIO instance did retain the 'flags' variable that's declared and set 
in its initializer, then mode_string could use it to determine the difference 
between wb+ and rb+.

I would be happy to write a patch for this.

Yes, both 'fr' and 'rf' need to be supported (and all upper/lower variants). 
And in the future, maybe 'fb' (and 'rfb', 'bfr', ...).

Unfortunately, the regex doesn't scale well for all of the combinations.

[issue25300] Enable Intel MPX (Memory protection Extensions) feature

[Florin Papa]

Florin Papa added the comment:

No modifications need to be made to the small object allocator. The malloc 
situation was just an example, it does not mean that setting pointer bounds 
occurs only in a malloc call. It also occurs when you declare a static array or 
when you initialize a new pointer:

int *x = (int*)malloc(10 * sizeof(int));
int *y = x; // the bounds for x will be passed on to y

When using "fcheck-pointer-bounds -mmpx" _all_ memory accesses will be 
instrumented.

Re: python3.5 + reportlab + windows again

[Robin Becker]

.


well it seems someone can build these extensions properly. I used Christoph
Gohlke's reportlab build and although there are 3 failures in the latest tests I
don't see any crashes etc etc and all the failures are explainable. Last thing I
saw from him in respect of pyRXPU was to use extra_compile_args=['/Od']. I will
try that in the reportlab extension builds and see if the problems go away.


I figured out the problem I was having with windows vs python3.5. It seems that 
something has changed in the way extensions are loaded when using imp to 
override the normal import mechanism.


The following code works OK for python 2.7, 3.3 & 3.4, but fails fairly 
catastrophically when used in a complex way (ie running reportlab's tests). 
Simple usage appears to work ie when I run one test.



My extension loading code looks like this

##
def __hack__():
import sys, os, importlib, imp
if sys.modules['reportlab'].__path__[0].lower()!=r'c:\code\reportlab': 
return
from distutils.util import get_platform

archname = get_platform()

_p0=r'c:\repos\reportlab\build\lib.%s-%d.%d' % 
(archname,sys.version_info[0],sys.version_info[1])
_p1=r'c:\repos\pyRXP\build\lib.%s-%d.%d' % 
(archname,sys.version_info[0],sys.version_info[1])

_overrides={
'reportlab.lib._rl_accel':os.path.join(_p0,r'reportlab\lib'),

'reportlab.graphics._renderPM':os.path.join(_p0,r'reportlab\graphics'),
'pyRXPU':_p1,
}
def find_override(name):
if name in _overrides and os.path.isdir(_overrides[name]):
fpd = imp.find_module(name.split('.')[-1],[_overrides[name]])
try:
try:
return imp.load_module(name,fpd[0],fpd[1],fpd[2])
except:
pass
finally:
if fpd[0]: fpd[0].close()

class RLImporter(object):
def __init__(self):
self.module = None

def find_module(self, name, path=None):
m = find_override(name)
if m:
m.__loader__ = self
self.module = m
return self

def load_module(self, name):
if not self.module:
raise ImportError("Unable to load module %s" % name)
sys.modules[name] = m = self.module
self.module = None
return m
sys.meta_path.insert(0, RLImporter())
__hack__()
del __hack__
##

My guess is that it's not cool any more to use imp.load_module repeatedly or 
that the hack of passing the found module about using a temporary attribute is 
not a good idea.



The intent of the above code is to allow me to build extensions for multiple 
pythons in a single area under c:\repos\reportlab\build and allow loading of 
those with different python versions. I don't want to pollute my repository with 
different extensions so prefer to keep them in the build area (and they change 
very slowly compared to the python code).


Is there some simple sample code that can be used as a model for this. I've 
tried looking at the importlib docs and my brain is bursting. I also looked at
http://chimera.labs.oreilly.com/books/123000393/ch10.html, but that seems 
all about normal python models/packages.


I think importlib has split the loading of extensions into a different method, 
and there seem to be assertions about re-using an existing loader.

Any python .py file can be either run as a main program or module (ie,

for both, it should end with

The latter is ofter to call a function main() defined previously.  If

[issue25300] Enable Intel MPX (Memory protection Extensions) feature

[Antoine Pitrou]

Antoine Pitrou added the comment:

The small object allocator uses large mmap-allocated arenas of 256 KB (IIRC) 
and carves small objects out of it.  So unless the pointer returned by 
PyObject_Malloc() has its bounds set manually using one of the intrinsic 
functions (*), MPX would believe the bounds of small objects are the bounds of 
the 256 KB arenas containing them, right?

(*) I'm assuming __bnd_set_ptr_bounds()

There is a runtime cost associated with MPX instrumentation, which is kept to a 
minimum due to the use of hardware instructions and registers. When 
"fcheck-pointer-bounds -mmpx" compilation flags are set, instrumentation is 
enabled for _all_ memory acceses in the code. This means that when you perform 
a malloc, the pointer bounds will be set inside the malloc call, and then 
passed on to your variable. Alternatively, you can manually instrument only 
regions of interest in your code using GCC functions described here [1].

Please see __bnd_set_ptr_bounds here [1] for bound manipulation. In order to 
have a better understanding of what happens when using MPX, I suggest writing a 
simple C program and look at the assembly code generated (MPX instructions and 
registers begin with bnd). You can use the following steps:

gcc -g -c test.c -O2 -fcheck-pointer-bounds -mmpx
objdump -d -M intel -S test.o

[Christian Heimes]

Christian Heimes added the comment:

Thanks for your patch. There might be a simpler way. By default a SSLContext 
only caches server sessions. You can enable client session caching with:

  SSL_CTX_set_session_cache_mode(ctx, SSL_SESS_CACHE_CLIENT)

This may be sufficient for FTP over TLS since both sockets are created from the 
same context.

 
The new patch has a flaw. With the new SSLSession object a user could attempt 
to reuse a SSLSession with a different SSLContext. That's going to break 
OpenSSL.

>From SSL_set_session(3)

NOTES
   SSL_SESSION objects keep internal link information about the session 
cache list, when being inserted into one SSL_CTX object's session cache.  One 
SSL_SESSION object, regardless of its reference count, must therefore only be 
used with one SSL_CTX object (and the SSL objects created from this SSL_CTX 
object).

Re: change data in large excel file(more than 240 000 rows on sheet)

Which makes a nonsense of using a super-secure algorithm in many cases.

If you are doing in-place symmetric file encryption then it's the
security of the key hashing algorithm that matters much more than the
actual encryption used on the file.

Using ccrypt, enc, etc. for file encryption means the password that
encodes the encryption key is saved with the file so brute-force
attacks to get the key are quite straightforward.

[issue25342] test_json segfault on OpenBSD

[Stefan Krah]

Stefan Krah added the comment:

It's not noise, we also have problems on Windows with test_json.

In theory we should set Py_DEFAULT_RECURSION_LIMIT in Python/ceval.c
to appropriate values for the default OS stack sizes in order to get
a proper RuntimeError instead of a segfault.

For OpenBSD it's clearly too high for the default.  Could you try
to find a safe value (perhaps 500 instead of 1000) for OpenBSD's
default?

ANN: Eliot 0.9, the logging system with causality - now with journald support

[Itamar Turner-Trauring]

 
Eliot 0.9 is out, with a new utility for pretty-printing log messages
and native journald support [1]. You can now route Eliot logs to
journald and when an error occurs easily find all logged actions that
led up to that particular error, as opposed to most logging systems
where this would involve reading all the logs and figuring out which
ones apply and which to ignore. 

Most logging systems can tell you what happened; Eliot tells you _why_
it happened:

$ python linkcheck.py | eliot-tree
4c42a789-76f5-4f0b-b154-3dd0e3041445
+-- check_links@1/started
`-- urls: [u'http://google.com', u'http://nosuchurl']
+-- download@2,1/started
`-- url: http://google.com
+-- download@2,2/succeeded
+-- download@3,1/started
`-- url: http://nosuchurl
+-- download@3,2/failed
|-- exception: requests.exceptions.ConnectionError
|-- reason: ('Conn aborted', gaierror(-2, 'Name unknown'))
+-- check_links@4/failed
|-- exception: exceptions.ValueError
|-- reason: ('Conn aborted.', gaierror(-2, 'Name unknown'))

And here's the code that generated these logs (eliot-tree [2] was used
to render the output):

import sys
from eliot import start_action, to_file
import requests
to_file(sys.stdout)

def check_links(urls):
with start_action(action_type="check_links", urls=urls):
for url in urls:
try:
with start_action(action_type="download", url=url):
response = requests.get(url)
response.raise_for_status()
except Exception as e:
raise ValueError(str(e))

check_links(["http://google.com;], ["http://nosuchurl;])

Mike,

What happens if you do [Windows] + R (ie Start > Run), enter "python"
and click OK?

If it comes up with a Python window, what happens if you type this:

import sys
print(sys.executable)

You can do all this in one step if you're feeling adventurous:

Start > Run > python -i -c "import sys; print(sys.executable)"

[issue25342] test_json segfault on OpenBSD

[STINNER Victor]

STINNER Victor added the comment:

Would it be possible to compute the recursion limit depending on the current 
maximum C stack size? At least estimate it? I guess the sys.getdefaultlimit() 
is 1000 is an arbitrary value. I also know that the effective limit depends on 
the memory allocated on the stack by C functions. Calling a Python function and 
a function implemented in C is different :-/

First release of pytest-vw!

[Florian Bruhin]

Hey,

I'm happy to announce the first release of pytest-vw, a pytest plugin
which makes failing test cases succeed in continuous integration
tools.

See https://github.com/The-Compiler/pytest-vw for more information.

Of course, any similarities with a current event concerning (but not
limited to) a multinational automobile manufacturer are purely
coincidental.

(In all seriousness: This was mainly to try the excellent
cookiecutter[1] and cookiecutter-pytest-plugin[2] projects - it's also
inspired by (read: a blatant ripoff of) PHPunit VW)

I would like to see Python in use as much as anyone. However, I am not sure
we are doing users or ourselves much of a favor encouraging pieces of the
language be distributed in so many kits.

I do not know, but it does not seem that Java has much of this problem.
Everyone seems to know that Java should be installed on the system. There
is a clear way to have multiple versions of Java on one system.

There would be benefits in having a well structured way to do it. I am not
suggesting that other ways should be prohibited.

This approach would fit well with the Python maxim to pick one really good
way to do it.

The ratio (1000/8MB) seems to be stable on Linux. Perhaps we could

It's just an estimate of course.

Installation problem

[MICHAEL]

Hello, 

Please forgive a new user's ignorance. 

I am trying to install Python 3.5.0 on my laptop (Windows 10). The default 
installation directory is shown as c:\Users\(my user 
name)\AppData\Local\Programs\Python\Python35-32. However, if I select Custom 
Install then the default installation directory is c:\Program 
Files(x86)\Python3.5. 

In either case, after the installation is complete I cannot find a Python3.5 
directory under Program Files(x86) or the Users\... directory. The python.exe 
file can be located under c:\OpenOffice. Other python files are found scattered 
all over my hard drive in locations such as c:\ HamRadio\WSJT, or c:\Program 
Files(x86)\Cyberlink, or c:\CHIRP, or a variety of other directories, but never 
in the designated installation directory. 

Scattered files include: 
python.exe (in Open Office) 
python27.dll (in CHIRP) 
pythoncom27.dll (in CHIRP) 
python33.dll (in HamRadio\WSJT) 
python25.dll (in "Koan c:\Program Files(x86)\Cyberlink) 

I assume these various .dll files are used in the various other programs I have 
installed but I cannot understand, at the moment, why the main python program 
does not appear in the designated installation directory. 

Any ideas or suggestion you may have are most welcome and appreciated. 

Thanks very much, 
Mike Wolcott

[issue5380] pty.read raises IOError when slave pty device is closed

[Xavier de Gaye]

Xavier de Gaye added the comment:

TLPI (The Linux Programming Interface book) says about the pty implementation 
on linux, at section 5 of chapter 64:

If we close all file descriptors referring to the pseudoterminal slave, 
then:
a) A read() from the master device fails with the error EIO. (On some other 
UNIX implementations, a read() returns end-of-file in this case.)

and also adds this (which is slightly off topic here):

b)  A write() to the master device succeeds, unless the input queue of the 
slave device is full, in which case the write() blocks. If the slave device is 
subsequently reopened, these bytes can be read.

UNIX implementations vary widely in their behavior for the last case. On 
some UNIX implementations, write() fails with the error EIO. On other 
implementations, write() succeeds, but the output bytes are discarded (i.e., 
they can’t be read if the slave is reopened). In general, these variations 
don’t present a problem. Normally, the process on the master side detects that 
the slave has been closed because a read() from the master returns end-of-file 
or fails. At this point, the process performs no further writes to the master.

I'm asking to adjust the limit at _runtime_. getrlimit() is not

(Not entirely sure if you're serious...)

Those were elements of the other programs he mentioned which ship Python
as, eg, a scripting or even because they're partly or wholly implemented
in Python. Apart from the file locations, none of the DLL versions are
35: python27.dll, python33.dll etc.

[issue24848] Warts in UTF-7 error handling

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

The difference between 2.7 and 3.x is that 2.7 uses isalnum() in IS_BASE64, and 
3.x test concrete ranges. Therefore depending on platform and locale 2.7 can 
accept wrong bytes as BASE64 characters and return incorrect result. Following 
patch makes 2.7 code the same as 3.x. Tests are changed to fail with large 
probability with unpatched code ('\xe1' is an alnum on almost all 8-bit 
locales).

It doesn't really matter how much you add; any Caesar cipher is going
to fall easily to just a little bit of frequency analysis. Consider an
extreme case, where the range of X is the size of the entire Unicode
character set. If the message is written in a Latin-based character
set, chances are good that the majority of the characters will fall
within a range of <96, giving the attacker a great starting point to
brute-force from.

Those would all be different programs that have packaged up (part of)
Python with them - and in some cases, a very old version. You can
ignore those.

Did the installation give any complaints? It's possible that you'd
need to elevate privileges for the global installation, though you
should be able to install to your own user directory without
elevation.

[issue5380] pty.read raises IOError when slave pty device is closed

[Guido van Rossum]

Guido van Rossum added the comment:

Honestly, Antoine's patch looks reasonable to me (except that the names of the 
test modules perpetuate the confusion that pipes and ptys are similar).

Can someone just port that to 3.6? (The change in semantics is big enough that 
I don't think we should shove it into a bugfix release.)

In other news, the pty.py module is pretty pathetic. Kill or improve? It feels 
like one of those "included" batteries that runs out of juice after 5 minutes.

[Steve Dower]

Steve Dower added the comment:

Hopefully with the extra logging we'll be able to see if something is failing 
at the point of detection. Any failure here (permissions in registry, etc.) 
will cause the launcher to not be installed on upgrade (which might be the same 
as removing it... I need to spend more time working through the dependencies 
involved here because they are messy).

[issue25344] Enhancement to Logging - Logging Stack

[David Silverman]

New submission from David Silverman:

It would be useful to have the ability to push logs onto a stack. This way you 
can log events to the stack. If an error occurred, you could pop the stack and 
output the log events. If no error occurred, you could pop the stack and 
discard the logs.

An example would be when you call a function it could push logs onto the log 
stack as the function is executing. If an error is encountered, you can 
pop/output the logs to provide more details. But, if no error is encountered, 
the detailed logs can be popped and discarded.

[eryksun]

Start a command prompt; change to the directory that has the MSU, and run it 
with the option "/log:kb2999226.evtx". For me this creates kb2999226.evtx in 
the current directory, which can be converted to XML using wevtutil. If this 
doesn't create a log file, then possibly the .msu file association is 
incorrect. In that case, try running wusa.exe directly, e.g.

"%SystemRoot%\System32\wusa.exe" Windows8.1-KB2999226-x64.msu 
/log:kb2999226.evtx

New submission from Gowtham Nm:

I downloaded Python 3.5 version to install on Windows 10. But apparently, the 
installation does not succeed.
I have tried with lower version of Python also, the installation does not 
succeed on Windows 10.

Have attached the logs of the error. I have checked for the particular error 
code (seen in the screenshot attached) in various forums but none worked.

Looking forward to hear from your team.

[issue25345] Unable to install Python 3.5 on Windows 10

[eryksun]

eryksun added the comment:

Please attach "Python 3.5.0 (32-bit)_*_core_JustForMe.log", if it exists.

According to the log, initially the installer can't create a restore point 
because, I assume, you have the volume shadow copy (VSS) service disabled, i.e. 
the error code is ERROR_SERVICE_DISABLED (0x80070422). That shouldn't derail 
the installation, but it's unusual to disable this service since restore points 
are critically important in case something goes wrong while modifying the 
system.

Next, installing core.msi fails with the error code 
ERROR_INSTALL_ALREADY_RUNNING (0x80070652). This means you had an existing 
installation in progress. Check for running instances of msiexec.exe. If the 
existing installation process is hung, try installing Python 3.5 again after 
rebooting.

That's testing the SMTPServer.__init__() which looks fine.  It's the
SMTPChannel.__init__() that's broken.

The new installer for 3.5 doesn't create an "App Paths" key for
"python.exe" like the old installer used to do (see the old
Tools/msi/msi.py). Without that, unless python.exe is in the search
PATH, "Win+R -> python" and running "start python" in the command
prompt won't work. You can of course add the key manually as the
default value for
"[HKLM|HKCU]\Software\Microsoft\Windows\CurrentVersion\App
Paths\python.exe". IMO, this makes it the 'system' Python.



That's interesting. Any idea why it changed?

That seems fine to me. Alternatively you could pass shell=True to
Popen and then the original command should work verbatim (but see the
warnings about using shell=True).

Probably it's just an oversight. I doubt Steve Dower would have

Using pipe in a system call

[Cecil Westerhof]

I want to do the following Bash command in Python:
sqlite3 spreekwoorden.sqlite "SELECT spreekwoord FROM spreekwoorden;" | 
sort > spreekwoorden2.txt

The following does this in Python:
sqlite_pipe = Popen(
(
'sqlite3',
'spreekwoorden.sqlite',
'SELECT spreekwoord FROM spreekwoorden;'
),
stdout = PIPE
)
Popen(
(
'sort',
'--output=spreekwoorden2.txt',
),
stdin = sqlite_pipe.stdout
)

Is this the correct way, or is there a better way?


By the way: I want this because I just filled the table spreekwoorden
in my Python script and want to save it immediately.

[issue25318] Add _PyBytesWriter API to optimize Unicode encoders

[STINNER Victor]

STINNER Victor added the comment:

Oh, I was surprised to see same or worse performances for 
UTF-8/backslashreplace. In fact, I forgot to enable overallocation. With 
overallocation, it is now faster ;-)

I modified the API to put the "stack buffer" inside _PyBytesWriter API 
directly. I also reworked _PyBytesWriter_Alloc() to call  
_PyBytesWriter_Prepare() so _PyBytesWriter_Alloc() now supports overallocation 
as well. It was part of _PyBytesWriter design to support overallocation at the 
first allocation (_PyBytesWriter_Alloc), that's why we have 
_PyBytesWriter_Alloc() *and* _PyBytesWriter_Init(): it's possible to set 
overallocate=1 between init and alloc.

I pushed my change since it didn't kill performances. It's only a little bit 
smaller but on very short encode: less than 500 ns. In other cases, it's the 
same performances or faster.
