Comment #25 on issue 146 by kxepal: Up-to-dated view server
http://code.google.com/p/couchdb-python/issues/detail?id=146

It's good thing to review your own code after some time passed. This update  
includes a lot of fixes and even some new features:

global:
- removed global state and cross module references (WOO-HOO!)
- rewritten QueryServer api
- added SimpleQueryServer as high level abstraction on top of QS internals
- added MockQueryServer to help write unittests
- fix docstring and typos.
- query server logs are more useful now in debug mode
- update documentation with android paragraph and how to customize query  
server
- place TODO references to actual CouchDB issues: COUCHDB-729, COUCHDB-282,  
COUCHDB-1261, COUCHDB-898. I could fix them locally, but this will make  
more differences between original JS server and Python one.
- add more over 170 test cases

compiler:
- fix crush for compilation of source code with windows newlines
- fix double crush if function compilation failed
- fix crush for malformed base64 encoded egg
- fix crush on egg cache usage
- code refactoring

stream:
- abstraction from JSON module exception type on decode/encode operations

render:
- fix COUCHDB-1272
- code refactoring

validate:
- prevent query server crush by validate_doc_update on Python exceptions

views:
- reduce_output_overflow error now will be raised properly
- small refactoring
- document seal now works better with copy.deepcopy()

design functions:
- send(), start(), provides(), register_type() available only for show and  
list functions
- get_row() available only for list functions
- log() function is not proxy of logging.info anymore

All test passed for:
- Python 2.4 to 2.7
- PyPy 1.5 and 1.6
- Android 2.3.4 with Python for Android version 5 against CouchDB-1.0,  
andorid-0.1 and MobileFuton 1.7

Please, could someone review docstrings and sphinx docs? I'm sure  
documentation text is far from good state /:

I took a look at this, but I'm having some trouble getting the tests  
running. In particular, this bit doesn't seem to work, independent of the  
view server used:

djc@enrai couchdb-python $ python
Python 2.7.2 (default, Oct 24 2011, 10:16:20)
[GCC 4.5.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Meanwhile, this works just fine from the command-line:

djc@enrai couchdb-python $ python couchdb/view.py
["reset"]
true

I looked at the queryserver.zip from comment 25 and the files from comment  
6. It seems to me that the former is too large and complex to take into  
couchdb-python at this time. The stuff from comment 6 is much more simple,  
but I couldn't run the test suite due to the above issue.

Hi, Dirkjan!

Thanks for first review(: Actually, I never run it as subprocess, but if  
you take a look at couchdb/tests/testutil.py::QueryServer so it could be  
run as subprocess, just remove shell=True from Popen.

There is a huge difference between comment 6 and comment 25. It's not in  
code size, it's in bugs, code complexity, documentation, tests, features,  
logging and how easily you could extend it without getting things broken.  
Support of old CouchDB releases is not a little part of it, just a few  
functions that easily could be removed. For example, I've easily added  
multiprocessing support for qs#25 for map/reduce functions just by  
decorating server/views.py functions without touching source code.

Also, you have to change a look from comment 6 to comment 22. That was the  
last version of all-in-one-file queryserver, but it still buggy by design.

Main goal of qs#25 and all code splitting was to simplify future support,  
allow to extend it easy and help with couchapps unittesting because now you  
could run it not as subprocess. And it had been reached.

You may read changelogs in this thread and in my clone at viewserver  
branch, they are quite full.

Updated Python query server in attachments. After almost year usage in  
production there was fixed some small problems:
- Eventually crush on chunk encoding for _list functions.
- View lib cleanup on reset command
- Handle single named MIME type params e.g. application/pdf;base64
- Reduced useless logging output to improve they readability.
- Fix COUCHDB-1330.
- Fix crush on malformed MIME type.
- Couchapp modules no more needed to be wrapped into some scope: just write  
regular
Python code for them. For example:
{{{
   import datetime

   def foo(datetime=datetime):
       return  
datetime.datetime.utcnow().replace(microsecond=0).isoformat('T')

   exports['foo'] = foo

   def foo():
       return  
datetime.datetime.utcnow().replace(microsecond=0).isoformat('T')

   exports['foo'] = foo
