Original Pull Request: https://github.com/google/brotli/pull/448

State: closed
Merged: Yes

Add flush and finish methods to the Compressor object in
the extension module and change compress to only process data.
Now, one or more compress calls followed by a finish call
will be equivalent to a module-level compress call.

Note: To maximize the compression efficiency (and match
underlying Brotli behavior, the Compressor object compress
method does not guarantee all input is immediately written to
output. To ensure immediate output, call flush to manually
flush the compression buffer. Extraneous flushing can increase
the size, but may be required when processing streaming data.
