| 2011-04-20 18:19 <sharoon> cedk: can you explain what you meant by your last tweet ? | ||
| 2011-04-20 18:22 <cedk> sharoon: there is index in mongodb ? | ||
| 2011-04-20 18:22 <sharoon> cedk: yes | ||
| 2011-04-20 18:22 <cedk> sharoon: so it will be great to be able to define it in the field | ||
| 2011-04-20 18:22 <sharoon> cedk: http://www.mongodb.org/display/DOCS/Indexes | ||
| 2011-04-20 18:22 <cedk> sharoon: like we have select=1 in SQL | ||
| 2011-04-20 18:22 <sharoon> cedk: oh yes, resuse select = 1 ? | ||
| 2011-04-20 18:22 <sharoon> cedk: yes | ||
| 2011-04-20 18:23 <sharoon> cedk: adding a ticket for that | ||
| 2011-04-20 18:23 <cedk> sharoon: otherwise your search will not be efficient | ||
| 2011-04-20 18:24 <sharoon> cedk: yes | ||
| 2011-04-20 18:24 <cedk> sharoon: and you do that because you have a lot of products :-) | ||
| 2011-04-20 18:24 <sharoon> cedk: oh yes i have over a million of them :D | ||
| 2011-04-20 18:25 <cedk> sharoon: next step is to find a way to edit Mongo field in the GTK client :-) | ||
| 2011-04-20 18:25 <sharoon> cedk: its already there | ||
| 2011-04-20 18:26 <cedk> sharoon: where? | ||
| 2011-04-20 18:26 <cedk> sharoon: wait... | ||
| 2011-04-20 18:26 <sharoon> cedk: like MongoAttribute is dislayed using default widget | ||
| 2011-04-20 18:26 <cedk> sharoon: ok I understand | ||
| 2011-04-20 18:26 <sharoon> cedk: but yes MongoDocument is stillr epresented as a JSON | ||
| 2011-04-20 18:28 <sharoon> cedk: https://bitbucket.org/sharoonthomas/trytond-mongodb/issue/1/use-of-indexes | ||
| 2011-04-20 18:28 <sharoon> ACTION out for lunch, brb | ||
| 2011-04-20 18:29 <cedk> sharoon: do you think this kind of fields could be added dynamicly? | ||

| 2011-04-20 22:42 <sharoon> cedk: I have some performance improvements to make, its too naive like __slots__ optimisation for some classes like the http://hg2.tryton.org/trytond/file/5f1bf7c0591e/trytond/transaction.py#l8 etc | ||
| 2011-04-20 22:42 <sharoon> cedk: is there still time for me to propose a patch ? | ||
| 2011-04-20 23:06 <cedk> sharoon: I'm not sure it will improve something | ||
| 2011-04-20 23:08 <cedk> sharoon: have you benchmark? | ||
| 2011-04-20 23:11 <cedk> sharoon: slots are there to limit memory usage | ||
| 2011-04-20 23:11 <cedk> sharoon: but for Transaction, there is only one instance per request | ||
| 2011-04-20 23:11 <cedk> so the gain is very limited | ||

| 2011-04-20 23:13 <cedk> sharoon: for info: http://stackoverflow.com/questions/472000/python-slots | ||
| 2011-04-20 23:19 <sharoon> cedk: any issues ? | ||
| 2011-04-20 23:20 <cedk> sharoon: ??? | ||
| 2011-04-20 23:21 <sharoon> cedk: got it now | ||
| 2011-04-20 23:21 <cedk> sharoon: it is bad practice to optimise stuff that doesn't need | ||
| 2011-04-20 23:22 <sharoon> cedk: i thought it was getting intialised too many times let me recheck a profile count i got | ||
| 2011-04-20 23:22 <cedk> sharoon: if you are concern, you can have a look at https://bugs.tryton.org/roundup/issue1892 | ||
| 2011-04-20 23:24 <cedk> sharoon: and we should really get your read with tuple for 2.2 | ||
| 2011-04-20 23:25 <sharoon> cedk: thats something we got to discuss | ||
| 2011-04-20 23:25 <sharoon> cedk: i was doing some experiments and these are my findings | ||
| 2011-04-20 23:25 <sharoon> cedk: 1. creation of dict is slow | ||
| 2011-04-20 23:26 <sharoon> cedk: 2. but pickling of tuple, list and dict are fastest and custom objects including named tuples dont match it | ||
| 2011-04-20 23:27 <cedk> sharoon: what do you want to discuss? | ||
| 2011-04-20 23:27 <sharoon> cedk: 3. when compression is used the dict's repeating keys are removed and hence the compression ensures there is not much overhead just because we use dict | ||
| 2011-04-20 23:27 <sharoon> cedk: read with tuple benefits | ||
| 2011-04-20 23:29 <cedk> sharoon: I'm convinced that we must go to tuple | ||
| 2011-04-20 23:29 <sharoon> cedk: ok | ||
| 2011-04-20 23:30 <sharoon> cedk: and returna list of tuple with the first tuple as column headers ? | ||
| 2011-04-20 23:30 <cedk> sharoon: no header | ||
| 2011-04-20 23:30 <sharoon> cedk: ok | ||
| 2011-04-20 23:30 <cedk> sharoon: the header is the list you give | ||
| 2011-04-20 23:30 <sharoon> ok | ||
| 2011-04-20 23:31 <sharoon> cedk: we automatically insert id | ||
| 2011-04-20 23:31 <cedk> sharoon: we will remove this feature :-) | ||
| 2011-04-20 23:32 <sharoon> cedk: :D you get what you ask for and in that case fields_names must be a required argument | ||
| 2011-04-20 23:32 <cedk> sharoon: yes | ||
| 2011-04-20 23:32 <cedk> sharoon: and we must ensure that the order is the same as the list of ids | ||
| 2011-04-20 23:32 <sharoon> cedk: On a separate note what do you think of __slots__ optimisation of browse node ? | ||
| 2011-04-20 23:33 <sharoon> cedk: agree | ||
| 2011-04-20 23:33 <cedk> sharoon: I think it is a waste of time because we will merge Browse with Model | ||
| 2011-04-20 23:34 <cedk> sharoon: and slots will be a no way | ||
| 2011-04-20 23:34 <sharoon> cedk: Active Record pattern | ||
| 2011-04-20 23:34 <sharoon> !! | ||
| 2011-04-20 23:34 <cedk> sharoon: yes it is on the roadmap | ||
| 2011-04-20 23:35 <cedk> so much to do, so little time | ||
| 2011-04-20 23:35 <sharoon> cedk: but you do realise that an insatnce of a model is gonna be huge right | ||
| 2011-04-20 23:36 <sharoon> cedk: i guess it may be better to have browse record is a descriptor | ||
| 2011-04-20 23:36 <cedk> sharoon: why? | ||
| 2011-04-20 23:36 <sharoon> cedk: will each record not represent an instance of the Model ? | ||
| 2011-04-20 23:37 <cedk> sharoon: yes | ||
| 2011-04-20 23:37 <sharoon> cedk: "so much to do, so little time" => "call for a sprint of x days" | ||
| 2011-04-20 23:38 <sharoon> cedk: for example an instance of ModelSQL (eq to pool.get('x')) alone has over 100 attributes in methods etc, its huge | ||
| 2011-04-20 23:39 <cedk> sharoon: the attributes are not on the instance | ||
| 2011-04-20 23:40 <sharoon> cedk: ok ? | ||
| 2011-04-20 23:40 <cedk> sharoon: it will not be very different then what we have now | ||
| 2011-04-20 23:40 <cedk> sharoon: it will be just more Pythonic | ||
| 2011-04-20 23:40 <sharoon> cedk: ok | ||
| 2011-04-20 23:41 <cedk> sharoon: I don't think for now that memory consumption is an issue for Tryton | ||
| 2011-04-20 23:42 <sharoon> cedk: http://paste.pocoo.org/show/375459/ | ||

| 2011-04-20 23:42 <cedk> sharoon: I could say that __search_domain_calc need some love | ||
| 2011-04-20 23:43 <cedk> sharoon: but it will be improved with pysql | ||
