"""
Verify that (i.e. check whether) the Pandas DataFrame provided
satisfies the constraints in the JSON .tdda file provided.
Mandatory Inputs:
df A Pandas DataFrame, to be checked.
constraints_path The path to a JSON .tdda file (possibly
generated by the discover_constraints
function, below) containing constraints
to be checked.
Optional Inputs:
epsilon When checking minimum and maximum values
for numeric fields, this provides a
tolerance. The tolerance is a proportion
of the constraint value by which the
constraint can be exceeded without causing
a constraint violation to be issued.
With the default value of epsilon
(EPSILON_DEFAULT = 0.01, i.e. 1%), values
can be up to 1% larger than a max constraint
without generating constraint failure,
and minimum values can be up to 1% smaller
that the minimum constraint value without
generating a constraint failure. (These
are modified, as appropraite, for negative
values.)
NOTE: A consequence of the fact that these
are proportionate is that min/max values
of zero do not have any tolerance, i.e.
the wrong sign always generates a failure.
type_checking: 'strict' or 'sloppy'.
Because Pandas silently, routinely and
automatically "promotes" integer and boolean
columns to reals and objects respectively
if they contain nulls, strict type checking
can be problematical in Pandas. For this reason,
type_checking defaults to 'sloppy', meaning
that type changes that could plausibly be
attriuted to Pandas type promotion will not
generate constraint values.
If this is set to strict, a Pandas "float"
column c will only be allowed to satisfy a
an "int" type constraint if
c.dropnulls().astype(int) == c.dropnulls().
Similarly, Object fields will satisfy a
'bool' constraint only if
c.dropnulls().astype(bool) == c.dropnulls().
report: 'all' or 'fields'
This controls the behaviour of the __str__
method on the resulting PandasVerification
object (but not its content).
The default is 'all', which means that
all fields are shown, together with the
verification status of each constraint
for that field.
If report is set to 'fields', only fields for
which at least one constraint failed are shown.
NOTE: The method also accepts
'constraints', which will be used to
indicate that only failing constraints for
failing fields should be shown.
This behaviour is not yet implented.
Returns:
PandasVerification object. This object has attributes:
passed # Number of passing constriants
failures # Number of failing constraints
It also has a .to_frame() method for converting the results
of the verification to a Pandas DataFrame, and a __str__
method to print both the detailed and summary results of
the verification.
Example usage (see tdda/constraints/examples/simple_verification.py
for slightly fuller example).

"""
Returns historical data on one or several RICs
Parameters
----------
rics: string or list of strings
Single RIC or List of RICs to retrieve historical data for
start_date: string or datetime.datetime or datetime.timedelta
Starting date and time of the historical range.
string format is: '%Y-%m-%dT%H:%M:%S'. e.g. '2016-01-20T15:04:05'.
datetime.timedelta is negative number of day relative to datetime.now().
Default: datetime.now() + timedelta(-100)
You can use the helper function get_date_from_today, please see the usage in the examples section
end_date: string or datetime.datetime or datetime.timedelta
End date and time of the historical range.
string format could be
- '%Y-%m-%d' (e.g. '2017-01-20')
- '%Y-%m-%dT%H:%M:%S' (e.g. '2017-01-20T15:04:05')
datetime.timedelta is negative number of day relative to datetime.now().
Default: datetime.now()
You can use the helper function get_date_from_today, please see the usage in the examples section
interval: string
Data interval.
Possible values: 'tick', 'minute', 'hour', 'daily', 'weekly', 'monthly', 'quarterly', 'yearly' (Default 'daily')
Default: 'daily'
fields: string or list of strings
Use this parameter to filter the returned fields set.
Available fields: 'TIMESTAMP', 'VALUE', 'VOLUME', 'HIGH', 'LOW', 'OPEN', 'CLOSE', 'COUNT'
By default all fields are returned.
count: int, optional
Max number of data points retrieved.
calendar: string, optional
Possible values: 'native', 'tradingdays', 'calendardays'.
corax: string, optional
Possible values: 'adjusted', 'unadjusted'
normalize: boolean, optional
If set to True, the function will return a normalized data frame with the following columns 'Date','Security','Field'.
If the value of this parameter is False the returned data frame shape will depend on the number of rics and the number of fields in the response.
There are three different shapes:
- One ric and many fields
- Many rics and one field
- Many rics and many fields
Default: False
Remark: This parameter has a less precedence than the parameter rawOutput i.e. if rawOutput is set to True, the returned data will be the raw data and this parameter will be ignored
raw_output: boolean, optional
Set this parameter to True to get the data in json format
if set to False, the function will return a data frame which shape is defined by the parameter normalize
Default: False
debug: boolean, optional
When set to True, the json request and response are printed.
Default: False
Raises
------
Exception
If request fails or if server returns an error.
ValueError
If a parameter type or value is wrong.

Note
----
This function also collects and summarizes runtime
workload statistics, which may introduce additional
overhead. This overhead can be avoided by directly
instantiating a :class:`Solver` object and
calling the :func:`Solver.solve` method.
Parameters
----------
problem : :class:`pybnb.Problem <pybnb.problem.Problem>`
An object that defines a branch-and-bound problem
comm : ``mpi4py.MPI.Comm``, optional
The MPI communicator to use. If unset, the
mpi4py.MPI.COMM_WORLD communicator will be
used. Setting this keyword to None will disable the
use of MPI and avoid an attempted import of
mpi4py.MPI (which avoids triggering a call to
`MPI_Init()`).
dispatcher_rank : int, optional
The process with this rank will be designated the
dispatcher process. If MPI functionality is disabled
(by setting comm=None, or when comm.size==1), this
keyword must be left at 0. (default: 0)
log_filename : string, optional
A filename where solver output should be sent in
addition to console. This keyword will be ignored if
the `log` keyword is set. (default: None)
results_filename : string, optional
Saves the solver results into a YAML-formatted file
with the given name. (default: None)
**kwds
Additional keywords to be passed to
:func:`Solver.solve`. See that method for additional
keyword documentation.
Returns
-------
results : :class:`SolverResults <pybnb.solver_results.SolverResults>`
An object storing information about the solve.

Reference coordinate array of shape ``(3,)`` or ``(n, 3)`` (dtype is
