> Micro-optimization of TTransport.py
> -----------------------------------
>
> Key: THRIFT-4007
> URL: https://issues.apache.org/jira/browse/THRIFT-4007
> Project: Thrift
> Issue Type: Improvement
> Components: Python - Library
> Reporter: Nathan Jensen
> Assignee: James E. King, III
> Priority: Trivial
> Labels: easyfix, performance
> Fix For: 0.11.0
>
>
> Method readAll(self, sz) in class TTransportBase in TTransport.py can be
> optimized to only call len(chunk) once. It currently calls len(chunk) twice,
> i.e.
> {code}
> def readAll(self, sz):
> buff = b''
> have = 0
> while (have < sz):
> chunk = self.read(sz - have)
> have += len(chunk)
> buff += chunk
> if len(chunk) == 0:
> raise EOFError()
> return buff
> {code}
> That results in two method invocations to len(chunk) but it can be reduced to
> one method invocation to len(chunk). Depending on the amount of data being
> read, the extra len(chunk) method invocations can add up to slightly slower
> performance.
