a79ec1c6cd test_util.py: use SHA-256 from pycryptopp instead of MD5 from hashlib (for uses in which any hash will do), since hashlib was only added to the stdlib in Python 2.5. 2010-08-05 22:00:51 -07:00

43c5032105 util/spans.py: __nonzero__ cannot return a long either. for #1154 2010-08-05 11:55:07 -07:00

8844655705 One fix for bug #1154: webapi GETs with a 'Range' header broke new-downloader. 
The Range header causes n.read() to be called with an offset= of type 'long',
which eventually got used in a Spans/DataSpans object's __len__ method.
Apparently python doesn't permit __len__() to return longs, only ints.
Rewrote Spans/DataSpans to use s.len() instead of len(s) aka s.__len__() .
Added a test in test_download. Note that test_web didn't catch this because
it uses mock FileNodes for speed: it's probably time to rewrite that.

There is still an unresolved error-recovery problem in #1154, so I'm not
closing the ticket quite yet.

cbcb728e7e Add a byte-spans utility class, like perl's Set::IntSpan for .newsrc files. 
Also a data-spans class, which records a byte (instead of a bit) for each
index.

d888bf3377 Clean up log.err calls, for one of the issues in #889. 
allmydata.util.log.err() either takes a Failure as the first positional
argument, or takes no positional arguments and must be invoked in an
exception handler. Fixed its signature to match both foolscap.logging.log.err
and twisted.python.log.err . Included a brief unit test.

fc3bd0c987 use added secret to protect convergent encryption 
Now upload or encode methods take a required argument named "convergence" which can be either None, indicating no convergent encryption at all, or a string, which is the "added secret" to be mixed in to the content hash key.  If you want traditional convergent encryption behavior, set the added secret to be the empty string.

This patch also renames "content hash key" to "convergent encryption" in a argument names and variable names.  (A different and larger renaming is needed in order to clarify that Tahoe supports immutable files which are not encrypted content-hash-key a.k.a. convergent encryption.)

This patch also changes a few unit tests to use non-convergent encryption, because it doesn't matter for what they are testing and non-convergent encryption is slightly faster.
