Plugins can now define their own annotation tie- breaker when two revisions introduce the exact same line. The Bazaar team is happy to announce availability of a new release of the bzr adaptive version control system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from http://bazaar-vcs.org/ Download as a source tarball; packages for various systems will be available soon. -- Bob Tanner tan...@real-time.com Key fingerprint = F785 DDFC CF94 7CE8 AA87 3A9D 3895 26F1 0DDB E378 -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations.html
Re: Problems with sys.stout.flush()

That's not how streams work, chief. Once you output (and flush)
something you can't un-output it.
What you probably want to do is to write a carriage return (\r)
which usually causes the cursor to return to the beginning of the
line, so that any new text you write overwrites the old text.
This has nothing to do with flushing; flushing doesn't erase or clear
the old input. Flushing is usually needed for a different reason,
however, namely standard output doesn't actually get sent to the
console until it sees a newline (\n) unless you flush the buffer.
Try to adapt this example to your problem:
for i in xrange(11):
sys.stdout.write('*'*(10-i) + ' '*i + '\r')
sys.stdout.flush()
time.sleep(2)
Notice that you have to print out spaces as well, to overwrite the
previous characters on the line (well, it might not be strictly needed

Hey,
The only reason I didn't supply full details is because I thought it may
just be something simple I was missing. Sorry for the confusing. Well
here's the full code.
import sys, os
from time import sleep
class progress:
def progressbar(self, number, total, char):
percentage = float(number*100)/total
percentage = int(round(percentage))
percentage = int(100 - percentage)
self.f=sys.stdout
if percentage 0:
char = char * percentage
self.f.write(char)
self.f.flush()
sleep(0.2)
def countlines(self, file):
lineCount = 0
f = open(file)
it = iter(f)
try:
while it.next():
lineCount += 1
except StopIteration:
pass
return lineCount
def main():
p = progress()
lines = 5
#lines = p.countlines(/tmp/junk)
count = lines
for i in xrange(lines):
p.progressbar(count, lines, *)
count -=1
print Finished
if __name__ == __main__:
main()
For now we can ignore the countlines() function. I need a nice progress
display e.g. ** continuing on til it reaches 100% I
need this to print out on one line only. At the moment it does do this,
only problem is its appends the print out from the last print out. I
need it to clear the last print out and then print the new print out
without appending the last.
So when it prints a progress at 50% it will print 50 (*) characters and
if the next progress is 51% it will print 51 (*) characters including
the last 50 (*) characters, so instead on ending up with 100 (*)
characters I end up with a shit load of them depending on how many lines
I pass to the progressbar() function.
Needed Output:
***Finished
Current Output:
Finished
Note: As you can see I'm only sending 5 lines to the progressbar()
function and It prints this many characters, so you could imagine if I
have 1 lines I would end up with a heap of * characters.

Abstract Classes
I am implementing a set of specifications that were designed to be OO language neutral. Several classes are specified as being abstract; so therefore there should be no instances of them, correct? However in the classes that are subclasses what is the correct way in Python to implement them? I am using the zope.interface module as well. For example: class IA(Interface): m = Int() p = TextLine() class IB(Interface): x = Bool() s = Text() class A(object): This is an abstract class with attributes m is an int and p is a string implements(IA) pass class B(A): implements(IB) def __init__(self,m,p,x,s): m=m p=p x=x s=s or should it be like: class A(object): This is an abstract class with attributes m is an int and p is a string implements(IA) def __init__(self,m,p): m=m p=p class B(A): implements(IB) def __init__(self,m,p,x,s): A.__init__(m,p) x=x s=s or maybe even: class B(A): implements(IB) def __init__(self,m,p,x,s): super(A.__init__(m,p)) x=x s=s Thanks for any pointers.

Here's why: when you write char = char * percentage, you are setting char to a string, so on the next iteration char is the string you printed last time. Thus char grows factorially with iterations. Not good.

So my question is instead of keeping separate lists for each destination node's shortest path. How can I represent and store them in a tree structure using python. Then I can easily find out what are the common nodes in the path to each destination. If I understand correctly, you want to know the path given the end-node. Common sense dictates that you use back links if that has to be done with decent efficiency. The back links can be added as part of the algorithm. Thanks once again.

PureData py/pyExt into standalone python
Hi guys, Short version: I've written some python classes for py/pyExt extensions for the dataflow graphical programming environment PureData. Here's an example PureData screenshot for clarity: see: http://i40.tinypic.com/2rrx6gy.jpg My classes talk to eachother via the PureData system, and they talk to the outside world via pyPortMIDI (which enables raw MIDI data communication). PureData encourages modularisation, so I've written several classes: * some that receive raw MIDI data, * some that parse this into human-readable tokens, * some that just generate human-readable tokens, * and some that parse human-readable tokens then send raw MIDI data I want to join these together as a stand-alone python application, using internal python communication instead of PureData... ...but I don't know how to do this. The only python I know comes from writing using the pyExt API, and the PureData API (which is written in C). Long(er) version: Miller Pukette's PureData: http://puredata.info/ Thomas Grill's Flext: http://puredata.info/Members/thomas/flext Thomas Grill's Py/Pyext: http://puredata.info/Members/thomas/py/ John Harrison's PyPortMIDI: http://www.media.mit.edu/~harrison/code.html CMU's PortMIDI: http://www.cs.cmu.edu/~music/portmusic/ PureData is a graphical dataflow programming environment that (among many, many other things!) allows for very rapid development of Audio and MIDI processing. Objects in PureData (and MaxMSP) communicate by sending messages through patch cords that connect an outlet to an inlet of another object. Thomas Grill's py/pyExt allows python code to be embedded as a PureData object. The benefit being that this python code can be effortlessly ported across multiple platforms (win32/linux/osx) and also to the highly related (but more commercial) Cycling'74 MaxMSP system. (PureData object code is written in C and generally not easy to port between platforms, nor between PD and MaxMSP - so writing portable python objects is a boon!) a pyExt object sends messages from its outlets using the line: self._outlet(outlet_id,message_to_send) a pyExt object performs actions when a message arrives at an inlet. An integer arriving at inlet 1 could be attached to this method code: def int_1(self,*arg): print received integer:,arg[0] If these pieces of code were in separate python classes - how would I connect two objects together such that an integer was passed between the two? If the first object sent 42, in puredata it would look like this: http://i44.tinypic.com/15eh74p.gif useless fact: the screenshot doubles up (i.e. pyext sender sender) due to the first word being the python file (i.e. sender.py), whilst the second is the name of the object class (i.e class sender (pyext._class) Maybe a more tricky question is: PureData supports message busses - messages sent to named busses can be broadcast to multiple locations. How would I connect objects up in this way using python? a pyExt object registers to receive messages on a certain bus using: self._bind(bus_name,self.method_to_call) def method_to_call(self,*arg): print a message on, bus_name, arrived print the message was, len(arg), long print and had the values, arg, inside a pyExt object sends messages to a particular bus by using: self._send(bus_name,message_to_send) -- http://mail.python.org/mailman/listinfo/python-list

Replacing module with a stub for unit testing
Hi, I'm working on a unit test framework for a module. The module I'm testing indirectly calls another module which is expensive to access --- CDLLs whose functions access a database. test_MyModule ---MyModule---IntermediateModule--- ExpensiveModule I want to create a stub of ExpensiveModule and have that be accessed by IntermediateModule instead of the real version test_MyModule ---MyModule---IntermediateModule--- ExpensiveModuleStub I tried the following in my unittest: import ExpensiveModuleStub sys.modules['ExpensiveModule'] = ExpensiveModuleStub # Doesn't work But, import statements in the IntermediateModule still access the real ExpensiveModule, not the stub. The examples I can find of creating and using Mock or Stub objects seem to all follow a pattern where the fake objects are passed in as arguments to the code being tested. For example, see the Example Usage section here: http://python-mock.sourceforge.net. But that doesn't work in my case as the module I'm testing doesn't directly use the module that I want to replace. Can anybody suggest something? Thanks, Scott -- http://mail.python.org/mailman/listinfo/python-list

Optimizing math functions
Hello all, I would like to maximize or minimize a given math function over a specific set of values, in Python preferably. I was checking out Wolfram Alpha (http://www70.wolframalpha.com/) and it can do simple optimization problems in math, such as maximize 15*x - x**2 over 0 to 15 (http://www70.wolframalpha.com/input/?i=maximize+15*x+-+x**2+over+0+to+15) which finds the maximum value and input for x in the range 0 to 15. Very cool. (This is of course a very simple example). What it apparently can't do is for maximize (or minimize) functions that contain two variables, x and y, or more. So for example a simple example would be maximize x**2 + y**2 over x:0 to 15, y:0-12 -- this does not work -- though I'm unclear about -- the correct syntax too. Is there some sort of simple Python module that would allow me to evaluate this type of function? In this particular instance I am interested in the minimum of x * sin(4*x) + 1.1 * sin(2*y), where x,y in range 0-10 though in other problems the range may not be identical for x and y. Thanks, Esmail ps: Does anyone know if Octave or some other free Linux (or Windows) program might also do this in a simple way? My preference would still be a Python solution that would be simple to use, ie plug in the function, the ranges and have it pop out the solution :-) -- http://mail.python.org/mailman/listinfo/python-list

The ‘MiniMock’ library URL:http://pypi.python.org/pypi/MiniMock
addresses this by mocking objects via namespace.
If you know the code under test will import ‘spam.eggs.beans’, import
that yourself in your unit test module, then mock the object with
‘minimock.mock('spam.eggs.beans')’. Whatever object was at that name
will be mocked (until ‘minimock.restore()’), and other code referring to
that name will get the mocked object.

That's not how streams work, chief. Once you output (and flush)
something you can't un-output it.
What you probably want to do is to write a carriage return (\r)
which usually causes the cursor to return to the beginning of the
line, so that any new text you write overwrites the old text.
This has nothing to do with flushing; flushing doesn't erase or clear
the old input. Flushing is usually needed for a different reason,
however, namely standard output doesn't actually get sent to the
console until it sees a newline (\n) unless you flush the buffer.
Try to adapt this example to your problem:
for i in xrange(11):
sys.stdout.write('*'*(10-i) + ' '*i + '\r')
sys.stdout.flush()
time.sleep(2)
Your example prints a new line each time,
Did you run it and observe what happened, or did you just guess what
it actually did? On my system it doesn't print new lines.

Well, based on the code you posted it doesn't look like your progress
bar is fine.
Anyway, you haven't described the problem you are having very well,
and we can guess what might be wrong but if you want better help
you're going to have to describe your problem more coherently. Give
us the
1. What code are you actually running (cut-and-paste, please, don't

3. What does the code actually output when you run it (cut-and paste,

4. Include any tracebacks if there are any.
In the meantime, I repeat my suggestion that you take my example and

because it always prints a trailing whitespace. Use sys.stdout.write
for it.

Hey,
The only reason I didn't supply full details is because I thought it
may just be something simple I was missing. Sorry for the confusing.
Well here's the full code.
import sys, os
from time import sleep
class progress:
def progressbar(self, number, total, char):
percentage = float(number*100)/total
percentage = int(round(percentage))
percentage = int(100 - percentage)
self.f=sys.stdout
if percentage 0:
char = char * percentage
self.f.write(char)
self.f.flush()
sleep(0.2)
def countlines(self, file):
lineCount = 0
f = open(file)
it = iter(f)
try:
while it.next():
lineCount += 1
except StopIteration:
pass
return lineCount
def main():
p = progress()
lines = 5
#lines = p.countlines(/tmp/junk)
count = lines
for i in xrange(lines):
p.progressbar(count, lines, *)
count -=1
print Finished
if __name__ == __main__:
main()
For now we can ignore the countlines() function. I need a nice
progress display e.g. ** continuing on til it
reaches 100% I need this to print out on one line only. At the moment
it does do this, only problem is its appends the print out from the
last print out. I need it to clear the last print out and then print
the new print out without appending the last.
So when it prints a progress at 50% it will print 50 (*) characters
and if the next progress is 51% it will print 51 (*) characters
including the last 50 (*) characters, so instead on ending up with 100
(*) characters I end up with a shit load of them depending on how many
lines I pass to the progressbar() function.
Needed Output:
***Finished
Current Output:
Finished
Note: As you can see I'm only sending 5 lines to the progressbar()
function and It prints this many characters, so you could imagine if I
have 1 lines I would end up with a heap of * characters.

If you have a directory in your PYTHONPATH before the standard library directories that has a string module, for example, absolute_import will not help you. I was getting confused by the fact that when I print sys.path from the python shell, the first entry is an empty string. This empty string must denote the current directory though, because: ['', '/usr/lib/python25.zip', '/usr/lib/python2.5', '/usr/lib/ python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/ python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/ usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/ Numeric', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/ site-packages/gst-0.10', '/var/lib/python-support/python2.5', '/usr/ lib/python2.5/site-packages/gtk-2.0', '/var/lib/python-support/ python2.5/gtk-2.0'] When I have this sys.path, doing an import string from a module where I have absolute imports enabled will still import the string module in the package (which also means it is in the same directory in this case.) So I think my string.py is being imported not because it is in the same package, but because the home directory is searched first. The empty string doesn't make much sense though (at least in a Unix system, you would imagine it would be something like './') but I guess that synce Python is platform independent, the empty string is taken to denote the current directory.

No, you're confusing two different problems:
(1) Scale the width of the progress bar to 100 characters;
(2) Make the progress bar appear on one line instead of multiple lines.
To solve the *second* problem, use the hint already given by Carl Banks.
To solve the *first* problem, use mathematics, then re-do your method,
because your method is wrong. Before you can write code to solve this
problem, you first have to get the mathematics right: you want to scale
the width of the progress bar to be 100 asterisks no matter how many
lines you have.
(a) If you have exactly 100 lines, and you draw one asterisk per line,
then you get a progress bar of exactly 100 asterisks.
(b) If you have 50 lines, and you want a progress bar of exactly 100
asterisks, you need to draw *two* asterisks per line.
(c) If you have 200 lines, and you want a progress bar of exactly 100
asterisks, you need to draw *one half* an asterisk per line (or one
asterisk per *two* lines).
(d) If you have N lines, and you want a progress bar of exactly 100
asterisks, each line must be equivalent to [] asterisks.
Once you have filled in the blank, then go back to writing code.
Some further hints: I've added some commentary to your code:
def progressbar(self, number, total, char):
percentage = float(number*100)/total
percentage = int(round(percentage))
percentage = int(100 - percentage)
# Why not combine all of the above into one line?
# percentage = int(100 - round(number*100.0/total))
self.f=sys.stdout
# Why are you storing stdout as an attribute to the method? Unless
# you will need it again elsewhere, this is a waste.
if percentage 0:
char = char * percentage
# Carl Banks has already pointed out the problem here.
self.f.write(char)
self.f.flush()
# Better written like this:
# sys.stdout.write(char)
# sys.stdout.flush()
sleep(0.2)
Finally, here's a function that should do what you ask for:
from __future__ import division
import sys
def progressbar(number, total, char='*', maxwidth=100):
done = number/total
if not 0 = done = 1:
raise ValueError('number or total out of range')
# Scale done=1 = maxwidth chars.
s = int(done*maxwidth)*char
sys.stdout.write(s + '\r')
sys.stdout.flush()
sleep(0.2)
This should work in normal terminal windows (tested on Linux, should
work on Windows and Mac too) but some IDEs may mess it up.

I'm not sure why you're puzzled; it could be the question of why 16, but i suspect it's because you can't see who creates this x attribute. Unlike languages like Java and C++, object attributes are not fixed at the time the class is compiled. Some attributes are created by the placement of the code, for example the method name f. But others are created in the code of the class (typically the __init__() method), and others can be created by anyone, at any time. I don't know why the tutorial starts with this, but it illustrates that an object is really just a container for attributes, some of which are callable (methods), and some of which are data (what Java would call fields). Anybody with an object reference can create, modify or delete those attributes. If it's being done inside the class methods, you use the syntax self.counter.

I have a regex that needs multiline flag. Some where I read I can pass multiline flag in regex string itself without using re.compile. If anybody have any idea about how to do that please reply. As detailed at [1], (?iLmsux) (One or more letters from the set 'i', 'L', 'm', 's', 'u', 'x'.) The group matches the empty string; the letters set the corresponding flags: re.I (ignore case), re.L (locale dependent), re.M (multi-line), re.S (dot matches all), re.U (Unicode dependent), and re.X (verbose), for the entire regular expression. (The flags are described in Module Contents.) This is useful if you wish to include the flags as part of the regular expression, instead of passing a flag argument to the compile() function. So you should be able to insert (?m) at the beginning of your regexp to make it multiline. -tkc [1] http://docs.python.org/library/re.html -- http://mail.python.org/mailman/listinfo/python-list

Several classes are specified as being abstract; so therefore there should be no instances of them, correct? However in the classes that are subclasses what is the correct way in Python to implement them? That very much depends on the classes, and how much the abstract classes do. With the very simple examples you give which have no methods even, I'd be strongly tempted not to implement the classes at all. But let's assume that's not a good idea (and there are plenty of reasons for it not to be a good idea, to be fair). Caution: I am not in the slightest bit familiar with the zope.interface module, which does make your IA and IB classes look exceptionally pointless. Again, it's fairly safe to presume that I'm wrong there :-) I am using the zope.interface module as well. For example: class IA(Interface): m = Int() p = TextLine() class IB(Interface): x = Bool() s = Text() class A(object): This is an abstract class with attributes m is an int and p is a string implements(IA) pass class B(A): implements(IB) def __init__(self,m,p,x,s): m=m p=p x=x s=s Presumably you mean self.m = m self.p = p and so on? This doesn't seem to be a consistent approach. Class B enforces initialisation of all its attributes, including the inherited ones, but class A doesn't. or should it be like: class A(object): This is an abstract class with attributes m is an int and p is a string implements(IA) def __init__(self,m,p): m=m p=p class B(A): implements(IB) def __init__(self,m,p,x,s): A.__init__(m,p) x=x s=s Modulo the self. as before, this is more consistent. or maybe even: class B(A): implements(IB) def __init__(self,m,p,x,s): super(A.__init__(m,p)) x=x s=s I have a bit of an allergy to super() because it works in slightly unexpected ways.

So am I to understand that there is no consistency in string handling throughout the standard modules/objects/methods? Seems to make python a lot more complicated than it needs to be, but okay. What it seems like you're not understanding here is that regular expressions are a special case. \b means something in Python literals. It maps to a single character, \x08. It _is_ a single character. r\b is two characters, a slash followed by a b. Regular expressions have an _entire_ range of their own special characters that have nothing to do with Python special characters. For regular expressions, \b -- that is, a slash followed by a b -- are TWO characters (not one, like \b is to Python) that have special meaning. Raw strings really exist SO you can do this. So you can do r\b and have the slash-followed-by-b be encoded into two characters, which the re library can then threat as a test for the blank string. Otherwise, you'd have to do \\b and similar a LOT when building up regular expressions... The re library just has its own rules for how it interprets strings. Its not no consistency. Its that regular expressions have meaning outside of Python and Python's implementation follows that general meaning (some, mostly, or to some other definition of how much). --S -- http://mail.python.org/mailman/listinfo/python-list

Seems to make python a lot more complicated than it needs to be, but okay. No, you are imagining complexity that doesn't exist. To the Python compiler, a string is a string is a string. The rules are very simple: you write a string literal using quotation marks to tell the compiler the text between these delimiters are a literal string. Here are the delimiters understood by Python: Regular strings, must be on a single line: ' ' or Regular strings, allowed to include multiple lines: ''' ''' or Raw strings, must be on a single line: r' ' or r Raw strings, allowed to include multiple lines: r''' ''' or r Regular strings interpret backslash escapes specially: \c has special meaning depending on what c is. For example, \t is interpreted by the compiler as a tab, and \n is interpreted as a newline. Raw strings *don't* interpret backslashes specially (except that you can't end the raw string with an odd number of backslashes). That is how you *create* string literals. It is 100% consistent all through Python: the rules apply in every module, in every function, everywhere, because the compiler creates the string before the function or module gets a chance to see the string. Having been created, how the string is *used* depends on the application, and Python modules and functions are no different. Inside a calculator application, the meaning of the literal string x/y would be very different than it would be inside an application dealing with file names. Python modules are no different: - the os module interprets many strings as file names according to the rules for your operating system: e.g. on Linux '/' separates parts of the pathname into sub-directories. On Windows, either forward or backslashes are used to separate directories, and ':' is used to separate drive letters from the path. - the glob module interprets strings according to the rules for shell globbing: e.g. '*' means 'match any number of any character', '?' means 'match a single of any character'. - the re module interprets strings according to the rules for regular expressions: e.g. '.*' means 'match any number of any character (except newline by default)' and '\d' (backslash-d) means 'match a single decimal digit'. - the urllib and urllib2 modules interpret strings according to the rules of dealing with URLs. In every case, you construct the string literals using the same rules, but the *meaning* of them differs according to the application. Because regular expressions give special meanings to literal backslashes, it is inconvenient to create many regexes using regular strings, because you need to escape the backslashes. That's where raw strings are more useful. -- Steven -- http://mail.python.org/mailman/listinfo/python-list

If you have a directory in your PYTHONPATH before the standard library directories that has a string module, for example, absolute_import will not help you. I was getting confused by the fact that when I print sys.path from the python shell, the first entry is an empty string. This empty string must denote the current directory though, because: ['', '/usr/lib/python25.zip', '/usr/lib/python2.5', '/usr/lib/ ...] When I have this sys.path, doing an import string from a module where I have absolute imports enabled will still import the string module in the package (which also means it is in the same directory in this case.) Mmm, I don't understand this. Do you mean that the current directory is a package (that is, it contains an __init__.py file? And the main script is there? Then, from Python's POV, it is NOT a package; packages are recognized only at import time; if you execute a script that happens to be inside a package directory, Python is not aware of the packageness of such directory. In that case, all imports are absolute. The current directory should not be a package (at least, not a package accessible from sys.path), nasty things may happen. So I think my string.py is being imported not because it is in the same package, but because the home directory is searched first. Yes. The empty string doesn't make much sense though (at least in a Unix system, you would imagine it would be something like './') but I guess that synce Python is platform independent, the empty string is taken to denote the current directory. Maybe you're surprised, but I don't think it's strange at all. Nobody writes open(./foo.txt) instead of open(foo.txt), and os.path.normpath(./foo.txt) is actually foo.txt.

[issue960325] --require feature option for configure/make (fail if building not possible)
Björn Lindqvist bjou...@gmail.com added the comment: I'm not Hallvard but I'd also appreciate this feature. I think it is quite important to have for automated build systems; Python seem to build correctly but then down the line some other package fails because the bz2 module is not available. IMHO it is wrong that you _can_ build python without libbz2 (for example) because what you get is a broken standard library. It is not mentioned anywhere in the documentation that bz2 is an optional module. I think terminating the build at the configure step if libbz2 is not found would be correct. Otherwise maybe the standard --with configure options could be used for this. E.g. ./configure --with-bz2 --with-ssl etc. -- nosy: +bjourne ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue960325 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue6060] PYTHONHOME should be more flexible (and controllable by --libdir)
soundmurderer soundmurde...@gmail.com added the comment: OK, I'm convinced. Changing PYTHONHOME is bad. But I am all in favor R. David Murray's solution of extending to include something like PYTHONHOMELIB. Martin v. Löwis: What I want is simply to be able to use --libdir to tell ./configure where to put standard Python libs, and I want my Python installation to recognize this lib location without having to hack PYTHONPATH or PYTHONHOME or anything else. This would make the behavior of --libdir exactly what people generally expect from using configure scripts supplied by many other projects. As of now, setting --libdir doesn't even do anything, silently! But even fixing --libdir per patch in http://bugs.python.org/issue858809 still doesn't work because the lib path has a hardcoded component. I just think that a sys admin, when he/she sees a configure script, should be able to tell it what to do via flags, run it, and expect it to Do The Right Thing, without worrying about the Python-specific workarounds to make libs and bins go to the desired place. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6060 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5259] smtplib is broken in Python3
José Luis Cáceres j...@telefonica.net added the comment:
There is a similar problem that I found with encode_cram_md5 in
smtplib.py, SMTP.login() method. I used the solution proposed by miwa,
both for PLAIN and CRAM MD5 authentication. Additionally, for the last
one, I had to introduce a second correction and byte encode the
password string when passing it to hmac.HMAC.
I do not know if I did things correctly, but just in case it can help
here is the complete patch that I used and worked well with the two
AUTH methods. I keep the original and modified lines for clarity.
def encode_cram_md5(challenge, user, password):
challenge = base64.decodestring(challenge)
#response = user + + hmac.HMAC(password,
challenge).hexdigest()
response = user + + hmac.HMAC(password.encode(),
challenge).hexdigest()
#return encode_base64(response)
return encode_base64((response).encode('ascii'), eol='')
def encode_plain(user, password):
#return encode_base64(\0%s\0%s % (user, password))
return encode_base64((\0%s\0%s % (user, password)).encode
('ascii'), eol='')
