[PYCBC-105] Provide simple 'raw' view API

Fri, 17 May 2013 14:21:10 -0500

This API will just provide a means by which a user can get a view results. Paths will be passed verbatim to LCB, and the view payload may be handled as a subclass of the Result object

[PYCBC-112] Add test to ensure objects can be pretty-printed

Thu, 16 May 2013 16:12:30 -0500

Write tests to ensure Result objects can be repr'd and stringified without errors.

[PYCBC-90] Allow FMT_PLAIN for 'normal' python strings.

Fri, 17 May 2013 14:25:06 -0500

Currently simple strings, i.e. "str" will not properly be set in "plain" mode. The library should apply some heuristics to determine if the string is a simple "byte" string, or whether it needs some special encoding.

[PYCBC-45] Remove Couchbase.save({'_id':'key', 'json':'doc'}) in favor of .set() doing key name detection

Thu, 30 Aug 2012 10:37:09 -0500

It seems .save() was added to do some special handling (_design/doc PUTing). It leans on doc._id which is going away in 2.0, so it "smells" if nothing else.

Additionally, leaning on .set() and cb['bucket']['key'] = 'value' for the API will give us great consistency and less confusion.

.save() should be deprecated
.set() should use JSON by default
.set() should handle keys named '_design/(*)' via the HTTP API

[PYCBC-39] Add Design document management, including error handling

Thu, 30 Aug 2012 14:24:08 -0500

Add the additional functionality needed to create and replace design documents. This will likely be an extension on the Bucket class.

[PYCBC-40] RESTful Bucket Flushing

Thu, 30 Aug 2012 23:21:47 -0500

Add the ability to call the RESTful bucket flush.

[PYCBC-31] python SDK disables all logging

Fri, 3 Aug 2012 12:02:10 -0500

took a few hours to find why logging in my python app stopped working, and it's because I started using the couchbase python SDK which strangely disables logging...

  logging.disable(logging.ERROR)

here...

  https://github.com/couchbase/couchbase-python-client/blob/master/couchbase/client.py#L33

the temporary workaround in my app was to call...

  logging.disable(logging.NOTSET)

but, that's just a hack workaround against a socially awkward (read: rude) implementation.

[PYCBC-16] increment from two clients seems to not work

Thu, 30 Aug 2012 15:51:49 -0500

This was originally observed with an older version, and in trying to reproduce it the latest change seems to show incr/decr is further broken. Still, this should be an easy test to add since it's been verified to fail.

from pymembase.membaseclient import VBucketAwareMembaseClient
client_one = VBucketAwareMembaseClient('http://host/pools/default','default','')
client_two = VBucketAwareMembaseClient('http://host/pools/default','default','')

# Client one sets a numeric key
client_one.set('jacob',0,0,'20')
client_one.get('jacob')

# Client two tries to increment this numeric key
client_two.incr('jacob')
# This returns (0, cas) - it should be 21!
# Client two can keep incrementing this weird key
client_two.incr('jacob')
# Returns (1, cas)

# However - if client two gets the key...
client_two.get('jacob')
client_two.incr('jacob')
# (21, cas)
# !!!

p.s.: want to thank oliland from IRC on reporting this

[PYCBC-17] client does not exit cleanly on interpreter exit

Fri, 6 Apr 2012 14:00:05 -0500

The couchbase client does not exit cleanly when the interpreter exits - i.e. does not disconnect unless you call client.done()

This can be fixed by daemonizing the CommandDispatcher threads. See http://docs.python.org/library/threading.html#threading.Thread.daemon

[PYCBC-14] incr() and decr() not working with VBucketAwareMembaseClient / Membase 1.7

Thu, 31 May 2012 23:30:39 -0500

See reproduction code attached. When executed it spits out a lot of errors ('amount') and eventually times out while still erroring in the background.

[PYCBC-3] decr() function fails gracelessly

Fri, 12 Aug 2011 13:11:38 -0500

While learning more about the functions in the vbucketawareclient I tried .decr() with minimal parameters. I lost control of my Python session as it didn't really fail gracefully. I wasn't really trying to make it work, but think this is broken :) and really hard to test further because of this tie-up.

Test script:

from couchbase.couchbaseclient import VBucketAwareCouchbaseClient as client
server = "http://localhost:8091/pools/default"
v = client(server,"default","")
# returns 11210
v.set("TESTKEY",0,0,"TESTVALUE")
# returns (4020540899, 602, '')
v.decr("TESTKEY",1)
#[2011-08-11 16:51:52,415] - [couchbaseclient] [4320661504] - ERROR - 'amount'
#[2011-08-11 16:51:52,627] - [couchbaseclient] [4320661504] - ERROR - 'amount'
#[2011-08-11 16:51:52,827] - [couchbaseclient] [4320661504] - ERROR - 'amount'
#.. never ends

[PYCBC-70] shutdown in client takes over 2 seconds

Sat, 4 May 2013 10:58:16 -0500

The shutdown function in the Couchbase object seems to take over 2 seconds.

From the discussion with the bug reporter:
@ingenthr it looks like the mc_client.done() is the culprit. the bucket is being deleted every request, calling mc_client.done() which is taking 2.3 sec to finish asa @ 2:00

oh? thanks for tracing that down! I'll get an issue filed ingenthr @ 2:00
perezd [~derek@23-24-210-193-static.hfc.comcastbusiness.net] entered the room. 2:00

client.Bucket asa @ 2:01
perezd left the room (quit: Client Quit). 2:01

that's interesting ingenthr @ 2:03
I wonder what it's doing there 2:03

is it bad to not properly shutdown? asa @ 2:08
looks like there is self._dispatcher_stopped_event.wait(2) 2:08

well, I think there's a configuration thread. it may leak something? I'm not certain to be honest ingenthr @ 2:08

comment it out and suddenly it iis very fast. asa @ 2:08
line 66 in couchbaseclient.py 2:09

heh ingenthr @ 2:09
well, this has been the area we need to fix I beleive 2:09

[PYCBC-107] Support py3's 'dict_keys' for multi methods

Wed, 15 May 2013 18:51:43 -0500

'dict_keys' should be supported, rather than forcing users to do list(d.keys()).

[PYCBC-114] Internal base management implementation

Thu, 16 May 2013 16:12:44 -0500

This is a 'basic' HTTP implementation. This will be the basis for views as well. As it stands now, this is an unstable API (i.e. the interface may (and probably *will*)) change. This task is just to get the code bits in order so that we're able to do less work when adjusting APIs

[PYCBC-108] Pass ascii=False to json.dumps

Thu, 16 May 2013 16:12:35 -0500

This will decrease the data size for UTF-8 strings. However this will store JSON as non-ascii. Is this supported? (it should be, as JSON says it's utf-8 by definition).

[PYCBC-111] Memory leak on bad arguments

Thu, 16 May 2013 16:13:05 -0500

There may be a memory leak in the MultiResult object if an error is thrown after the MultiResult object is allocated.

[PYCBC-116] Review error messages to ensure they're concise, informative, actionable

Sun, 19 May 2013 16:05:26 -0500

There are some like "Couldn't connect", which should be more from a user perspective.

[PYCBC-59] Provide Standardized Logging

Sun, 19 May 2013 16:07:18 -0500

Provides the consistent level of logging provided by other SDKs. Provide more information on configuring logging for developers.

[PYCBC-92] Provide 'codec' options for keys and values

Tue, 21 May 2013 09:01:28 -0500

This will be a preliminary interface, and would allow users to circumvent (either for interoperability or for bugs in the client) "hard coded" encoding rules (pun intended)

The constructor for the Connection class should accept a 'codec' which is an object providing the
following functions:

To encode:
encode_key(self, key) => key_as_bytearray

To decode:
decode_key(self, bytearray) => whatever

To encode a value; should return the bytearray and flags to use
encode_value(self, value) => (bytearray, flags)

To decode a value, function should look at flags and return a bytearray
possibly examining flags.

decode_value(self, value, flags) => bytearray

[PYCBC-106] Expose server list

Wed, 15 May 2013 18:51:06 -0500

This might be needed for more advanced handling of views, or integration of views into a more efficient, "native" HTTP client.

[PYCBC-15] client can't set() integer values

Tue, 24 Jul 2012 15:34:33 -0500

Attempting to set an integer value with the python client will produce:

TypeError: object of type 'int' has no len()

We should be getting the object length from the string (unicode?) representation of the object passed into set().
