testfixtures 3.0.1 Released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of testfixtures 3.0.1. This is a bug 
fix release featuring the following changes:


- Some documentation tweaks and clarifications.

- Fixed a bug which masked exceptions when using compare() with a broken 
generator.


- Fixed a bug when comparing a generator with a non-generator.

- Ensure LogCapture cleans up global state it may effect.

- Fixed replacement of static methods using a Replacer.

If you haven't bumped into it already, testfixtures is a collection of 
helpers for writing succinct unit tests including help for:


- Comparing objects and sequences

Better feedback when the results aren't as you expected along with 
support for comparison of objects that don't normally support comparison.


- Mocking out objects and methods

Easy to use ways of stubbing out objects, classes or individual methods 
for both doc tests and unit tests. Special helpers are provided for 
testing with dates and times.


- Testing logging

Helpers for capturing logging output in both doc tests and unit tests.

- Testing stream output

Helpers for capturing stream output, such as that from print statements, 
and making assertion about it.


- Testing with files and directories

Support for creating and checking files and directories in sandboxes for 
both doc tests and unit tests.


- Testing exceptions

Easy to use ways of checking that a certain exception is raised, even 
down the to the parameters the exception is raised with.


The package is on PyPI and a full list of all the links to docs, issue 
trackers and the like can be found here:

xlrd 0.7.9 released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of xlrd 0.7.9:

http://pypi.python.org/pypi/xlrd/0.7.9

This release fixes an annoying merge bug on my part that resulted in a 
"NameError: global name 'BYTES_X00' is not defined" error where opening 
certain Excel files.


Barring any more brown bag issues, this will be the last release in the 
0.7 series and the last release supporting Python 2.1 and 2.2.


The next release, in a week or so if there are no further 0.7 problems, 
will be 0.8.0 targeting Python 2.6 and upwards and featuring support for 
reading data from .xlsx files (although not formatting, unless some 
sponsorship or patches turn up). If you're interested in this, it would 
be great if you could try out the master branch and let us know if you 
find any problems:


https://github.com/python-excel/xlrd

There's also details of all things Python and Excel related here:

To try to do an exception in this case:

No.


- are there any possibly drawbacks of using SQLalchemy instead of the
   MySqlDB interface?


You won't be using it instead of mysqldb, you'll be using it as a layer 
over mysqldb.



   For the second point I guess that we might have a bit less fine
   tuning,


Not so, any tuning you can do direct against the dbapi driver can still 
be done through SQLAalchemy.



   Any other possible issue?


If you have problems, I'd suggest asking on the sqlalchemy mailing list:

xlrd 0.8.0 released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of xlrd 0.8.0:

http://pypi.python.org/pypi/xlrd/0.8.0

This release finally lands the support for both .xls and .xlsx files.
Many thanks to John Machin for all his work on making this happen.
Opening of .xlsx files is seamless, just use xlrd as you did before and 
it all should "just work".


xlrd 0.8.0 is also the first release that that targets Python 2.6 and 
2.7, but no Python 3 just yet. Python 2.5 and below may work but are not 
supported. If you need to use Python 2.5 or earlier, please stick to 
xlrd 0.7.x.


Speaking of xlrd 0.7.x, that's now in "requested maintenance only" mode 
;-) That means, if possible, use 0.8.x. If you have a really good reason 
for sticking with 0.7.x, and you find a bug that you can't work around, 
then please make this clear on the python-ex...@googlegroups.com and 
we'll see what we can do.


If you find any problems, please ask about them on the list, or submit 
an issue on GitHub:


https://github.com/python-excel/xlrd/issues

xlrd 0.9.0 released, now with Python 3 support!

[Chris Withers]

Hi All,

I'm pleased to announce the release of xlrd 0.9.0:

http://pypi.python.org/pypi/xlrd/0.9.0

This release means the supported versions of Python supported by xlrd 
are 2.6, 2.7, 3.2 and 3.3!


Very exciting stuff, and a massive thank you to
Thomas Kluyver (@takluyver on GitHub) for doing the bulk of the work to 
make this happen.


Also thanks to Martin Panter (@vadmium in GitHub, if I'm following 
correctly) for his additional work on the pull request and Manfred 
Moitzi for re-licensing his unit tests so we could include them.


This is obviously a big release, so I wouldn't recommend jumping on it 
in production just yet, but it would be great if people could get 
testing on both Python 2 and Python 3.


If you find any problems, please ask about them on the 
python-ex...@googlegroups.com list, or submit an issue on GitHub:


https://github.com/python-excel/xlrd/issues

To be clear, I wasn't asking for a change to existing behaviour, I was

niggles.

Sorry, I don't agree. It is *never* a good idea to install packages 
globally. Using virtualenv or similar (buildout, etc) gives you a 
single, cross platform way of not ending up with a mess of a python 
installation where you have a bunch of libraries of random versions 
installed, often with no way of finding out what version they are or how 
to uninstall them.


Heaven forbid you want to use or develop more than one project per 
machine; then you end up with different projects needing different 
versions of the same libraries and you're screwed. ;-)



The pip system does a good job o
managing package installs in the global context.


Ask the pip maintainers whether they'd suggest using pip on the global 
system python or inside a virtualenv...



see the point. On Windows the installer is the point of entry for 'package'
management, going outside that can get confusing.


"Python" should be though of as the application, not any individual 
library...



I also understand setting up a
Windows installer is non-trivial.


It isn't a lot of work from what I remember, I just don't like 
encouraging bad practices...



offing, the OP might find it easier to use the Python packaging from here on 
out.


What is "the Python packaging" you refer to?


xlrd3 - Library for developers to extract data from
Microsoft Excel (tm) spreadsheet files
xlrd1 - library for extracting data from Microsoft Excel
spreadsheet files


I would avoid both of these like the plague, it's a shame the people who

xlwt 0.7.4 released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of xlwt 0.7.4. This release has only 
a couple of changes in it:


- Python 2.3 to 2.7 are now the officially supported versions, no Python 
3 yet, sorry.


- The datemode in an xlwt Workbook can be set to 1904 by doing 
`workbook.dates_1904 = 1` and is written to the output file. However the 
datemode was not being reflected in conversions from datetime.datetime 
and datetime.date objects to floats for output, resulting in dates that 
were 4 years too high when seen in Excel.


For a full details, please see the GitHub repository:

https://secure.simplistix.co.uk/svn/xlwt/trunk

This release features the following changes:

- Google Spreadsheet doesn't write the undefined-contents byte at the

xlrd 0.7.8 released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of xlrd 0.7.8:

http://pypi.python.org/pypi/xlrd/0.7.8

This release features the following changes:

- Compatibility with Python 2.1 and 2.2 is restored.

- Fix for github issue #7: assertion error when reading file with 
xlwt-written bitmap. The assertion is now ignored and a warning logged 
if verbosity > 0.


- superfluous zero bytes at end of xls OBJECT records are now ignored.

For full details, please see the GitHub repository:

https://github.com/python-excel/xlrd

Barring any packaging issues or serious bugs, this will be the last 
release in the 0.7 series and the last release supporting Python 2.1 and 
2.2.


The next release, likely in a couple of weeks time, will be 0.8.0 
targeting Python 2.6 and upwards and featuring support for reading data 
from .xlsx files (although not formatting, unless some sponsorship or 
patches turn up). If you're interested in this, it would be great if you 
could try out the master branch and let us know if you find any problems:

mortar_rdb 1.2.0 released!

[Chris Withers]

Hi All,

I'm pleased to announce a new release of mortar_rdb.

This package ties together SQLAlchemy, sqlalchemy-migrate and
the component architecture to make it easy to develop projects
using SQLAlchemy through their complete lifecycle.

Changes in this release were:

- Pass None as the default for echo rather than False on the
  advice of Daniel Holth.

- When using mortar_rdb.registerSession, allow exlicit
  disabling of two-phase commit.

- No longer log passwords during session registration.

- Specify sqlalchemy 0.6 as a requirement, until
  zope.sqlalchemy is ported, mortar_rdb shouldn't be
  used with :mod:`sqlalchemy` 0.7.

If you'd like to see what mortar_rdb can do for you, please have a read 
of the narrative usage docs, which give a quick run through of the 
lifespan of a project developers using mortar_rdb:


http://packages.python.org/mortar_rdb/use.html

MailingLogger 3.4.0 Released!

[Chris Withers]

I'm pleased to announce a new release of Mailinglogger.

The handlers have the following features:

- customisable and dynamic subject lines for emails sent

- emails sent with a configurable headers for easy filtering

- flood protection to ensure the number of emails sent is not excessive

- support for SMTP servers that require authentication

- fully documented and tested

This release has no functional changes but finally ships with a full new 
set of Sphinx docs:

in search of graceful co-routines

[Chris Withers]

Hi All,

I'm looking for a graceful pattern for the situation where I have a 
provider of a sequence, the consumer of a sequence and code to moderate 
the two, and where I'd like to consumer to be able to signal to the 
provider that it hasn't succeeded in processing one element in the queue.


So, I'd want the controlling code to look a lot like:

for item in provider:
  try:
consumer.handleItem(self)
  except:
 provider.failed(item)

Now, since the sequence is long, and comes from a file, I wanted the 
provider to be an iterator, so it occurred to me I could try and use the 
new 2-way generator communication to solve the "communicate back with 
the provider", with something like:


for item in provider:
  try:
consumer.handleItem(self)
  except:
 provider.send('fail')
  else:
 provider.send('succeed')

..but of course, this won't work, as 'send' causes the provider 
iteration to continue and then returns a value itself. That feels weird 
and wrong to me, but I guess my use case might not be what was intended 
for the send method.


Anyway, I wonder how other people would write this?
(I'm particularly interested in a sane way to use the two way 
communication that PEP 342 introduced)


cheers,

Chris

On 18/05/2011 03:10, Terry Reedy wrote:

By default, Python iterators operate in pull mode -- consumers request a
new item when they want one. I believe .send was mostly intended to
reverse that, to operate in push mode where producers .send() a item to
a consumer when they are ready to. That is certainly true of examples I
have seen.


My first exposure was with the @inlineCallbacks decorator in twisted, 
which does use it both ways...



Using .send for feedback to a provider is trickier, as the two other
posts have shown.


The closest I've found to something graceful is:

def mygenerator(*args):
for arg in args:
print "yielding:",arg
result = yield arg
print "returned:",result
if result is not None:
yield None

provider = mygenerator(1,2,3)
for arg in provider:
print "got:",arg
if arg%2:
provider.send('hello')

However, if you do g.send(None), you still get a result back, which 
feels a bit weird...


It's pretty disappointing that neither the send nor throw methods added 
as part of PEP342 were provided with a parameter or variant that did 
"send an item but don't advance the generator".


> Another option is to write an iterator class instead

of generator function. You can then give the provider a message receive
method (.send or whatever) that is decoupled from the send-next method.


Yes, that's an option I'd considered, however, with a provider class as 
follows:


class Provider:

def __init__(self,*args):
self.args = args
self.current = 0

def next(self):
try:
val = self.args[self.current]
except:
raise StopIteration()
self.current += 1
print "yielding:",val
return val

def send(self,value):
print "returned:",value

def __iter__(self):
return self

provider = Provider(1,2,3)
for arg in provider:
print "got:",arg
if arg%2:
provider.send('hello')

...but that's a lot more code, and allows one of my anti-use cases to 
happen:


provider = Provider(1,2,3)
provider.send("don't want this to be possible")

The generator implementation deals with the above specific case:

  File "test.py", line 12, in 
provider.send('hello')
TypeError: can't send non-None value to a just-started generator

...which is, in itself, a little weird, given that it doesn't protect

testfixtures 5.2.0 released!

[Chris Withers]

   Hi All,

   I'm pleased to announce the release of testfixtures 5.2.0 featuring the
   following:

 * test_datetime and test_time now  accept a [1]datetime instance  during
   instantiation to set the initial value.
 * test_date now accepts a  [2]date instance during instantiation to  set
   the initial value.
 *Relax the restriction on adding, setting or
   instantiatingtest_datetimewithtzinfosuchthatif
   the tzinfo matches  the one configured,  then it's okay  to add.  This
   means  that  you   can  now  instantiate   a  test_datetime  with   an
   existing [3]datetime instance that has tzinfo set.
 * testfixtures.django.compare_model() now ignores [4]many to many fields
   rather than blowing up on them.
 * Drop official support for Python 3.4, although things should  continue
   to work.

   The package is on PyPI and a full list of all the links to docs, issue
   trackers and the like can be found here:

mush 2.7 released! - Type-based dependency injection for scripts

[Chris Withers]

Hi All,

I'm very happy to announce the a new release of Mush, a light weight

testfixtures 6.0.0 released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of testfixtures 6.0.0 featuring the 
following:


 * |compare()|
   
will
   now handle objects that do not natively support equality or
   inequality and will treat these objects as equal if they are of the
   same type and have the same attributes as found using|vars()|
   or|__slots__|.
   This is a change in behaviour which, while it could conceivably
   cause tests that are currently failing to pass, should not cause any
   currently passing tests to start failing.
 * Add support for writing to the|stdin|of|MockPopen|
   
instances.
 * The default behaviour of|MockPopen|
   
can
   now be controlled by providing a callable.
 * |LogCapture.actual()|
   
is
   now part of the documented public interface.
 * Add|LogCapture.check_present()|
   
to
   help with assertions about a sub-set of messages logged along with
   those that are logged in a non-deterministic order.
 * |Comparison|
   
now
   supports objects with|__slots__|.
 * Added|ShouldAssert|
   
as
   a simpler tool for testing test helpers.
 * Changed the internals of the various decorators testfixtures
   provides such that they can be used in conjunction
   with|unittest.mock.patch()|
   on
   the same test method or function.
 * Changed the internals of|ShouldRaise|
   
and|Comparison|
   
to
   make use of|compare()|
   
and
   so provide nested comparisons with better feedback. This finally
   allows|ShouldRaise|
   
to
   deal with Django’s|ValidationError|
   
.
 * Added handling of self-referential structures to|compare()|
   
by
   treating all but the first occurence as equal. Another change needed
   to support Django’s insane|ValidationError|
   
.

Thanks to Hamish Downer and Tim Davies for their work on|MockPopen| 
.


Thanks to Wim Glenn and Daniel Fortunov for their help reviewing some of 
the more major changes.

testfixtures 6.0.2 released - important bug fix!

[Chris Withers]

Hi All,

I'm afraid I've found quite a serious regression in the 6.x series of 
testfixtures releases:


Objects that had neither __dict__ nor __slots__ would always be 
considered equal by compare().
I hit this comparing datetimes, but this would also affect types 
provides by extensions in other languages such as C or C++.
This did not affect built-in types such as dict, set, tuple and list as 
they have specific comparers provided that were not affects.


I've released 6.0.2 to fix this and would urge anyone using 6.0.0 or 
6.0.1 to upgrade as soon as possible.

xlrd 0.9.4 released!

[Chris Withers]

Hi All,

Well, I've finally called it and tagged current master of xlrd as 1.0.0:

This release includes the following changes since the last release:

- Official support, such as it is, is now for 2.6, 2.7, 3.3+

- Fixes a bug in looking up non-lowercase sheet filenames by ensuring 
that the sheet targets are transformed the same way as the 
component_names dict keys.


- Fixes a bug for ragged_rows=False when merged cells increases the 
number of columns in the sheet. This requires all rows to be extended to 
ensure equal row lengths that match the number of columns in the sheet.


- Fixes to enable reading of SAP-generated .xls files.

- support BIFF4 files with missing FORMAT records.

- support files with missing WINDOW2 record.

- Empty cells are now always unicode strings, they were a bytestring on 
Python2 and a unicode string on Python3.

testfixtures 6.4.0 released - important bug fix! (again)

[Chris Withers]

   Hi All,

   I'm afraid I found quite a [1]serious problem with unittest.mock.call
   objects that is important for users of testfixtures' MockPopen helper.

   This release includes a monkey patch to fix that issue as well as a facade
   over both unittest.mock and the rolling backport on pypi, giving
   preference to the latter, so you don't have to change your code if you
   need to flip to the rolling backport for a while when waiting to a bug fix
   to land in Python core.

   This release also include:

 * Add official support for Python 3.7.
 * Drop official support for Python 3.5.
 * Better feedback when [2]call() comparisons fail when using compare().
 * A re-working of  MockPopen to enable it  to handle multiple  processes
   being active at the same time.
 * Fixes to Mocking dates and times documentation.

   The package is on PyPI and a full list of all the links to docs, issue
   trackers and the like can be found here:

mush 1.1 released! - Type-based dependency injection for scripts

[Chris Withers]

Hi All,

I'm very happy to announce the a new release of Mush, a light weight 
dependency injection framework aimed at enabling the easy testing and 
re-use of chunks of code that make up scripts.


This release rounds out a few rough edges after a few months of real 
world use:


- Runners can now be created from other Runners during instantiation or 
using the .extend() method as well as concatenation.


- @requires decorations can now be stacked

- Runners now have a .replace() method allowing you to replace a 
callable with a mock to make sure the callable is passed the right 
parameters.


For a worked example of how to use Mush to reduce the copy'n'paste in 
your scripts, please see here:


http://pythonhosted.org/mush/examples.html

Full docs are here:

mush 1.2 released! - Type-based dependency injection for scripts

[Chris Withers]

Hi All,

I'm very happy to announce the a new release of Mush, a light weight 
dependency injection framework aimed at enabling the easy testing and 
re-use of chunks of code that make up scripts.


This release rounds out a some more rough edges after even more real 
world use:


- The 'nothing' singleton is now used  instead of None for marking
  return types, fixing a bug that occurred when a callable tried to
  type-map a result that was None.

- Add an after() type wrapper for callables that need to wait
  until after a resource is used but that can't accept that resource
  as a parameter.

For a worked example of how to use Mush to reduce the copy'n'paste in 
your scripts, please see here:

MailingLogger 3.8.0 Released!

[Chris Withers]

I'm pleased to announce a new release of Mailinglogger.

Mailinglogger provides two handlers for the standard python
logging framework that enable log entries to be emailed either as the
entries are logged or as a summary at the end of the running process.

The handlers have the following features:

- customisable and dynamic subject lines for emails sent

- emails sent with a configurable headers for easy filtering

- flood protection to ensure the number of emails sent is not excessive

- support for SMTP servers that require authentication

- fully documented and tested

This release adds flood limiting to the SummarisingLogger, ensuring that 
emails it sends aren't bigger than MTAs are prepared to handle.


Full docs can be found here:

http://packages.python.org/mailinglogger/

For more information, please see:
http://www.simplistix.co.uk/software/python/mailinglogger
or

testfixtures 4.7.0 Released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of testfixtures 4.7.0. Since 4.5.1, 
the following have been added:


- Add the ability to pass raises=False to compare() to just get
  the resulting message back rather than having an exception raised.

- Fix a bug that mean symlinked directories would never show up when
  using TempDirectory.compare() and friends.

- Add the `followlinks` parameter to TempDirectory.compare() to
  indicate that symlinked or hard linked directories should be recursed
  into when using `recursive=True`.

The package is on PyPI and a full list of all the links to docs, issue 
trackers and the like can be found here:

mush 2.0 released! - Type-based dependency injection for scripts

[Chris Withers]

Hi All,

I'm very happy to announce a new release of Mush, a light weight 
dependency injection framework aimed at enabling the easy testing and 
re-use of chunks of code that make up scripts.


This release is a re-write dropping all the heuristic callable ordering 
in favour of building up defined sequences of callables with labelled 
insertion points.

testfixtures 4.8.0 Released!

[Chris Withers]

Hi All,

I'm pleased to announce the release of testfixtures 4.8.0 featuring the 
following:


- More succinct mocking with Replacer:

For setUp usage:

replace = Replacer()
replace('x.y.z', Mock())
self.addCleanup(replace.restore)

For one-shot context manager usage:

with Replace('x.y.z', Mock()) as the_mock:
...

Multi-replace context manager usage:

with Replacer() as replace:
dt = replace('x.y.z.datetime', test_datetime())
mock = replace('x.y.do_it', Mock())

- Two context managers for testing warnings:

with ShouldWarn(UserWarning("foo")):
warnings.warn('foo')

with ShouldNotWarn():
... code that should raise no warnings ...

4.8.0 or 4.9.0, that is the question, or should it be just how good is 
your version control? :)


Gah, I really need to automate the release emails to stop stupidity like 
that :-S


It's 4.9.0...

bugfix release that fixes the following:


- Fix bug that prevented logger propagation to be controlled by the
  log_capture decorator.

Thanks to John Kristensen for the fix.

It looks like I also forgot to send out the 4.1.0 release announcement, 
which was a bug and feature release containing the following:


- Fix compare() bug when dict instances with tuple keys were not equal.

- Allow logger propagation to be controlled by LogCapture.

- Enabled disabled loggers if a LogCapture is attached to them.

Thanks to Daniel Fortunov for the compare() fix.

which async framework?

[Chris Withers]

Hi All,

I see python now has a plethora of async frameworks and I need to try 
and pick one to use from:


- asyncio/tulip
- tornado
- twisted

From my side, I'm looking to experimentally build a network testing 
tool that will need to speak a fair few network protocols, both classic 
tcp and multicast-based, and have a web api living on top of it that 
most likely will have a websocket for pumping data to the browser.


I'd like to be able to serve the rest of the web api using a pyramid 
wsgi app if possible, and I'd like to be able to write the things that 
process requests in and validation out in a synchronous fashion, most 
likely spinning off a thread for each one.


The protocols are all financial (do we really not have a pure-python FIX 
library?!) but none are likely to have existing python implementations.


How should I pick between the options? What would people recommend and why?

cheers,

Chris

If you are writing 'standard' blocking, synchronous code, I am not sure
why you would use any of the above.


The idea I have is to do all the networking async based on a declarative 
set of messages in and recording all messages out and then hand that set 
of messages off to a syncronous layer to make assertions, record into a 
database, etc.

I know nothing of tornado. I personally would use asyncio over twisted
if I could because it is simpler, in the stdlib, has the option to write
'untwisted' non-blocking code similar to blocking code, and the docs
easier for me to read.


Thanks.

Guess I was expecting more of a response. I suspect I'll just end up 
cross-posting to the various mailing lists, which I hope won't cause too 
much offence or kick off any flame wars.


I'm faced with a difficult choice that I suspect many in our community 
are, just trying to find out how to make the best decision :-)

It would do both.


Ye of little faith :-P

I've been pleasantly surprised by the succinct, well reasoned and 
respectful replies from each of the communities!

which async framework? - a summary

As one who doesn't lurk on the other lists, is there a nice executive
summary of their responses?


Well, of course, each person recommended their own framework.

The short version was:

- tornado is a web server, if you're not using it, the async stuff is 
better developed elsewhere


- asyncio is very new, not a lot of protocols out in the wild and not 
much battle testing


- twisted is been around the block a lot, huge amounts of support and an 
active, knowledgeable community. Can feel crufty and old in parts, mind


The community bit swung it for me, so I've opted for Twisted, if I ever 
get a chance to work on the project in question ;-)
