| bigkevmcd | ganesh_ariveguru: you're not really providing enough information | 12:55 |
| bigkevmcd | ganesh_ariveguru: how are you storing the text file? are you indexing it? | 12:55 |
| *** teix has joined #zope | 12:55 | |
| bigkevmcd | ganesh_ariveguru: are you packing the database? | 12:55 |
| bigkevmcd | ganesh_ariveguru: FWIW, I just uploaded a 992k file into an otherwise empty Data.fs file, and it's not 1.1M | 12:57 |

| *** MrTango has quit IRC | 12:57 | |
| ganesh_ariveguru | no...i am not directly storing text files.... | 12:58 |
| ganesh_ariveguru | i am extracting content from text files | 12:58 |
| ganesh_ariveguru | and storing on it | 12:59 |
| *** MrTango has joined #zope | 13:02 | |
| ganesh_ariveguru | hi...bigkevmcd | 13:26 |
| ganesh_ariveguru | pls tell some solutions | 13:27 |
| ganesh_ariveguru | bigkevmcd: while appending data to db, it's size is growing rapidly | 13:27 |
| bigkevmcd | ganesh_ariveguru: that makes sense | 13:28 |
| bigkevmcd | ganesh_ariveguru: you're adding objects to the database | 13:28 |
| bigkevmcd | ganesh_ariveguru: if you have older, unreferenced objects, then packing will remove them | 13:28 |
| ganesh_ariveguru | bigkevmcd: but instead appending , if i stored all objects in one shot....db size is very less | 13:29 |
| bigkevmcd | ganesh_ariveguru: the Zope db stores a history of transactions | 13:29 |
| bigkevmcd | ganesh_ariveguru: packing will remove what it can | 13:29 |
| ganesh_ariveguru | how to do packing...when to do packing | 13:29 |
| *** zagy has quit IRC | 13:30 | |
| *** __mac__ has quit IRC | 13:30 | |
| ganesh_ariveguru | bigkevmcd:packing before each transactions? | 13:30 |
| bigkevmcd | ganesh_ariveguru: no, don't pack before each transaction | 13:30 |
| bigkevmcd | ganesh_ariveguru: pack daily or something | 13:30 |
| bigkevmcd | ganesh_ariveguru: that's what most folk do | 13:31 |
| ganesh_ariveguru | my transaction is done by a for loop.....for each object i'll append to db, and commit the transaction.... | 13:31 |
| ganesh_ariveguru | so it is growing and having history for each object | 13:32 |
| ganesh_ariveguru | so...how i can get rid of it... | 13:32 |
| bigkevmcd | ganesh_ariveguru: not necessarily | 13:32 |
| bigkevmcd | ganesh_ariveguru: only if the objects are changing | 13:32 |
| bigkevmcd | ganesh_ariveguru: there's a subtle difference between changing objects, and adding objects | 13:33 |
| ganesh_ariveguru | see.....this will be my one object in db{ | 13:35 |
| ganesh_ariveguru | "question_papers" : [{ | 13:35 |
| ganesh_ariveguru | "q_id " : "1", | 13:35 |
| ganesh_ariveguru | "question" : "some text" | 13:35 |

| ganesh_ariveguru | } | 13:35 |
| bigkevmcd | pastebin | 13:35 |
| ganesh_ariveguru | i question papers' list i will add, like this many elements{ | 13:36 |
| ganesh_ariveguru | "q_id " : "2", | 13:36 |

| ganesh_ariveguru | bigkevmcd you got what am asking? | 13:40 |
| bigkevmcd | ganesh_ariveguru: yes | 13:40 |
| *** tisto has quit IRC | 13:41 | |
| bigkevmcd | ganesh_ariveguru: and you're changing the top-level object, so it will maintain the history in each transaction | 13:41 |
| ganesh_ariveguru | so how to delete the history? | 13:41 |
| bigkevmcd | packing! | 13:42 |
| bigkevmcd | <ganesh_ariveguru> i have written my own ZODB class there is no pack method | 13:42 |
| bigkevmcd | I doubt that's true | 13:42 |
| bigkevmcd | but, if it is, you'll need to write your own | 13:42 |
| bigkevmcd | I suspect you're using the standard ZODB class | 13:42 |
| bigkevmcd | and, in that case, you can call pack on it | 13:42 |
| ganesh_ariveguru | wait i will post my ZOdb class | 13:43 |
| ganesh_ariveguru | bigkevmcd:http://paste.lisp.org/new/zope...how to select channel in this....\ | 13:44 |
| bigkevmcd | ganesh_ariveguru: select None and paste the URL | 13:44 |
| ganesh_ariveguru | http://paste.lisp.org/+2RRT | 13:46 |
| ganesh_ariveguru | bigkevmcd: i have pasted my zodb class there.... | 13:47 |
| bigkevmcd | sure | 13:47 |
| bigkevmcd | so, your pack method doesn't need that first line, but you're calling pack on the db, which is correct | 13:47 |
| ganesh_ariveguru | you told me based on my zodb class....how to write packing script....pls | 13:48 |
| bigkevmcd | call pack | 13:50 |
| bigkevmcd | it's as simple as that | 13:50 |
| ganesh_ariveguru | ya...when to call | 13:50 |
| bigkevmcd | at 18:01:33UTC | 13:51 |
| ganesh_ariveguru | after finishing all transactions..? | 13:51 |
| bigkevmcd | on alternate days, if they have a e in them | 13:51 |
| ganesh_ariveguru | nice comedy... | 13:51 |
| ganesh_ariveguru | a e, what's tha? | 13:51 |
| ganesh_ariveguru | what's that? | 13:51 |
| bigkevmcd | basically, call when you need to | 13:53 |
| bigkevmcd | if you really want to call after every transaction, I think that's stupid, but feel free | 13:53 |
| bigkevmcd | its your application | 13:53 |

| *** __mac__ has joined #zope | 14:08 | |
| bigkevmcd | ganesh_ariveguru: bear in mind that backing up a live zodb is fraught, so backup a .old might be desirable | 14:08 |

| bigkevmcd | ganesh_ariveguru: eh? | 14:28 |
| bigkevmcd | ganesh_ariveguru: why do you think that? | 14:28 |
| ganesh_ariveguru | consider if one person is using my application in his mobile....he will add new notes or some data to db, so after packing, .fs file will be there with reduced size, but .fs.old wil be with big size. ... so it will cause the application size, so i want to delete that... | 14:31 |
