fsdump test
===========
Let's get a temp file path to work with first.
>>> import tempfile
>>> path = tempfile.mktemp('.fs', 'Data')
>>> print 'path:', path #doctest: +ELLIPSIS
path: ...Data...fs
More imports.
>>> import ZODB
>>> from ZODB.FileStorage import FileStorage
>>> import transaction as txn
>>> from BTrees.OOBTree import OOBTree
>>> from ZODB.FileStorage.fsdump import fsdump # we're testing this
Create an empty FileStorage.
>>> st = FileStorage(path)
For empty DB fsdump() output definitely empty:
>>> fsdump(path)
Create a root object and try again:
>>> db = ZODB.DB(st) # yes, that creates a root object!
>>> fsdump(path) #doctest: +ELLIPSIS
Trans #00000 tid=... time=... offset=52
status=' ' user='' description='initial database creation'
data #00000 oid=0000000000000000 size=66 class=persistent.mapping.PersistentMapping
Now we see first transaction with root object.
Let's add a BTree:
>>> root = db.open().root()
>>> root['tree'] = OOBTree()
>>> txn.get().note('added an OOBTree')
>>> txn.get().commit()
>>> fsdump(path) #doctest: +ELLIPSIS
Trans #00000 tid=... time=... offset=52
status=' ' user='' description='initial database creation'
data #00000 oid=0000000000000000 size=66 class=persistent.mapping.PersistentMapping
Trans #00001 tid=... time=... offset=207
status=' ' user='' description='added an OOBTree'
data #00000 oid=0000000000000000 size=114 class=persistent.mapping.PersistentMapping
data #00001 oid=0000000000000001 size=30 class=BTrees._OOBTree.OOBTree
Now we see two transactions and two changed objects.
Clean up.
>>> st.close()
>>> st.cleanup() # remove .fs, .index, etc
