Access to objects with hash indices.

ROD allows for accessing objects via fields with hash indices,
which are useful for indices with millions of keys.
These are split accross multiple files for faster load-time.

Background
Given
the library works in development mode
Scenarios
  1. indexing with hash index
  2. extending the DB when hash index is used
  3. indexing of fields with different DBs for the same model with hash index
  4. indexing of particular values with hash index
  5. multiple objects with indexed fields with hash index
  6. iterating over the index key-values pairs
  7. indexing with empty database
indexing with hash index

Rod should allow to access objects via values of their fields,
for which indices were built.

Given
the class space is cleared
And
the model is connected with the default database
And
a class Caveman has a name field of type string with hash index
And
a class Caveman has an age field of type integer with hash index
And
a class Caveman has an identifier field of type ulong with hash index
And
a class Caveman has a height field of type float with hash index
When
database is created
And
I create a Caveman
And
his name is 'Fred'
And
his age is '25'
And
his identifier is '111222333'
And
his height is '1.86'
And
I store him in the database
And
I create another Caveman
And
his name is 'Barney'
And
his age is '26'
And
his identifier is '111222444'
And
his height is '1.67'
And
I store him in the database
And
I create another Caveman
And
his name is 'Wilma'
And
his age is '25'
And
his identifier is '111222555'
And
his height is '1.67'
And
I store her in the database
And
I reopen database for reading
Then
there should be 3 Caveman(s)
And
there should be 1 Caveman with 'Fred' name
And
there should be 1 Caveman with 'Wilma' name
And
there should be 1 Caveman with 'Barney' name
And
there should be 2 Caveman(s) with '25' age
And
there should be 1 Caveman with '26' age
And
there should be 1 Caveman with '111222333' identifier
And
there should be 1 Caveman with '111222444' identifier
And
there should be 1 Caveman with '111222555' identifier
And
there should be 2 Caveman(s) with '1.67' height
And
there should be 1 Caveman with '1.86' height
And
some Caveman with 'Fred' name should be equal to the first Caveman
And
some Caveman with 'Barney' name should be equal to the second Caveman
And
some Caveman with 'Wilma' name should be equal to the third Caveman
And
the first Caveman with 'Fred' name should be equal to the first Caveman
And
the first Caveman with 'Barney' name should be equal to the second Caveman
And
the first Caveman with 'Wilma' name should be equal to the third Caveman
When
database is created
And
I create a Caveman
And
his name is 'Fred'
And
I store him in the database
And
I create another Caveman
And
his name is 'Barney'
And
I store him in the database
And
I create another Caveman
And
her name is 'Wilma'
And
I store her in the database
And
I reopen database for reading
Then
there should be 3 Caveman(s)
And
there should be 1 Caveman with 'Fred' name
And
there should be 1 Caveman with 'Wilma' name
And
there should be 1 Caveman with 'Barney' name
And
some Caveman with 'Fred' name should be equal to the first Caveman
And
some Caveman with 'Barney' name should be equal to the second Caveman
And
some Caveman with 'Wilma' name should be equal to the third Caveman
And
the first Caveman with 'Fred' name should be equal to the first Caveman
And
the first Caveman with 'Barney' name should be equal to the second Caveman
And
the first Caveman with 'Wilma' name should be equal to the third Caveman
extending the DB when hash index is used

Rod should allow to extend the DB when the hash index is used.
The index should be properly updated.

Given
the class space is cleared
And
the model is connected with the default database
And
a class Caveman has a name field of type string with hash index
When
database is created
And
I create a Caveman
And
his name is 'Fred'
And
I store him in the database
And
I create another Caveman
And
his name is 'Barney'
And
I store him in the database
And
I reopen database
And
I create another Caveman
And
her name is 'Wilma'
And
I store her in the database
And
I create another Caveman
And
his name is 'Fred'
And
I store him in the database
And
I reopen database for reading
Then
there should be 4 Caveman(s)
And
there should be 1 Caveman with 'Wilma' name
And
there should be 2 Caveman(s) with 'Fred' name
And
there should be 1 Caveman with 'Barney' name
And
some Caveman with 'Fred' name should be equal to the first Caveman
And
some Caveman with 'Barney' name should be equal to the second Caveman
And
some Caveman with 'Wilma' name should be equal to the third Caveman
And
the first Caveman with 'Barney' name should be equal to the second Caveman
And
the first Caveman with 'Wilma' name should be equal to the third Caveman
indexing of fields with different DBs for the same model with hash index

The contents of indices should be fulshed when the database is reopened.

Given
the class space is cleared
And
the model is connected with the default database
And
a class Caveman has a name field of type string with hash index
When
database is created
And
I create a Caveman
And
his name is 'Fred'
And
I store him in the database
And
I create another Caveman
And
his name is 'Fred'
And
I store him in the database
And
I create another Caveman
And
his name is 'Fred'
And
I store him in the database
And
I reopen database for reading
And
I access the Caveman name index
And
database is created in tmp/location2
And
I create a Caveman
And
his name is 'Wilma'
And
I store him in the database
And
I create another Caveman
And
his name is 'Wilma'
And
I store him in the database
And
I create another Caveman
And
his name is 'Wilma'
And
I store him in the database
And
I reopen database for reading in tmp/location2
Then
there should be 3 Caveman(s)
And
there should be 3 Caveman(s) with 'Wilma' name
And
there should be 0 Caveman(s) with 'Fred' name
And
some Caveman with 'Wilma' name should be equal to the first Caveman
indexing of particular values with hash index
Given

And
the model is connected with the default database
And
a class Caveman has a name field of type string with hash index
And
a class Caveman has a surname field of type string with hash index
And
a class Caveman has a login field of type string with hash index
And
a class Caveman has an age field of type integer with hash index
When
database is created
And
I create and store the following Caveman(s):
name surname login age
John Smith john 12
Lara Croft lara 23
Adam Parker adam 12
Adam noob1 33
noob2 -1
Adam noob1 33
And
I reopen database for reading
Then
there should be 6 Caveman(s)
And
there should be 1 Caveman with 'John' name
And
there should be 2 Caveman(s) with 'Adam' name
And
there should be 2 Caveman(s) with '12' age
And
there should be 1 Caveman with '-1' age
And
there should be 2 Caveman(s) with '' name
And
there should be 2 Caveman(s) with '' surname
multiple objects with indexed fields with hash index

The database should properly store thausands of objects with some indexed fields.

Given
the class space is cleared
And
the model is connected with the default database
And
a class User has a name field of type string with hash index
And
a class User has a surname field of type string with hash index
And
a class User has an age field of type integer
When
database is created
And
I create a User
And
his name is 'John'
And
his surname is 'Smith'
And
his age is '21'
And
I store him in the database 1000 times
And
I create a User
And
her name is 'Lara'
And
her surname is 'Croft'
And
her age is '23'
And
I store her in the database 1000 times
And
I reopen database for reading
Then
there should be 2000 User(s)
Then
there should be 1000 User(s) with 'John' name
Then
there should be 1000 User(s) with 'Smith' surname
Then
there should be 1000 User(s) with 'Lara' name
Then
there should be 1000 User(s) with 'Croft' surname
And
some User with 'John' name should be equal to the first User
iterating over the index key-values pairs

It should be possible to iterate over the keys of a index.

Given
the class space is cleared
And
the model is connected with the default database
And
a class User has a name field of type string with hash index
When
database is created
And
I create a User
And
his name is 'John'
And
I store him in the database
And
I create a User
And
her name is 'Lara'
And
I store her in the database
And
I create a User
And
her name is 'Lara'
And
I store her in the database
And
I create a User
And
her name is 'Pipi'
And
I store her in the database
And
I reopen the database for reading
And
I iterate over the name index of User
Then
there should be 1 User with 'John' name in the iteration results
And
there should be 2 User(s) with 'Lara' name in the iteration results
And
there should be 1 User with 'Pipi' name in the iteration results
And
there should be 0 User(s) with 'Fred' name in the iteration results
indexing with empty database

Rod should behave well when there is an index on a model while
the database is created and nothing is stored in it.

Given
the class space is cleared
And
the model is connected with the default database
And
a class User has a name field of type string with hash index
When
database is created
And
I reopen the database for reading
Then
there should be 0 User(s)
