cryptography lib version 2.1.1 is causing problems
Revert changes to test_warcprox.py
Revert changes to bigtable and dedup
Revert warc to previous behavior
Update unit test
Replace invalid warcfilename variable in playback
Stop using WarcRecord.REFERS_TO header and use payload_digest instead
Check also that locking succeeds after the writer closes the WARC file.
Remove parametrize from ``test_warc_writer_locking``, test only for the
``no_warc_open_suffix=True`` option.
Change `1` to `OBTAINED LOCK` and `0` to `FAILED TO OBTAIN LOCK` in
``lock_file`` method.
Replace timestamp parameter with more generic extra_response_headers={}
When request has --header ``Warcprox-Meta: {\"accept\":[\"capture-metadata\"]}"``
Response has the following header:
``Warcprox-Meta: {"capture-metadata":{"timestamp":"2017-10-31T10:47:50Z"}}``
Update unit test
When client request has HTTP header ``Warcprox-Meta": {"return-capture-timestamp": 1}``,
add to the response the WARC record timestamp in the following HTTP header:
``Warcprox-Meta: {"capture-timestamp": '%Y-%m-%d %H:%M:%S"}``.
Add unit test.
On Linux, `fcntl.flock` is implemented with `flock(2)`, and
`fcntl.lockf` is implemented with `fcntl(2)` — they are not compatible.
Java `lock()` appears to be `fcntl(2)`. So, other Java programs working
with these files work correctly only with `fcntl.lockf`.
`warcprox` MUST use `fcntl.lockf`
Add multiple ``CdxServerDedup`` unit tests to simulate found, not found and
invalid responses from the CDX server. Use a different file
``tests/test_dedup.py`` because we test the CdxServerDedup component
individually and it belongs to the ``warcprox.dedup`` package.
Add ``mock`` package to dev requirements.
Rework the warcprox.dedup.CdxServerDedup class to have better exception
handling.
