99a046ab51 hashutil: convenience methods for tagged and encoded hashes 
In various cases, including Merkle Trees, it is useful to tag and encode the inputs to your secure hashes to prevent security flaws due to ambiguous meanings of hash values.

4b4f5bbcba change #!/usr/bin/python to #!/usr/bin/env python 
Note that using "whatever version of python the name 'python' maps to in the current shell environment" is more error-prone that specifying which python you mean, such as by executing "/usr/bin/python setup.py" instead of executing "./setup.py".  When you build tahoe (by running "make") it will make a copy of bin/allmydata-tahoe in instdir/bin/allmydata-tahoe with the shebang line rewritten to execute the specific version of python that was used when building instead of to execute "/usr/bin/env python".

However, it seems better that the default for lazy people be "whatever 'python' means currently" instead of "whatever 'python' meant to the manufacturer of your operating system".

78d19c271c rearrange service startup a bit, now Node.startService() returns a Deferred that fires when the tub is actually ready, and there is also a Node.when_tub_ready() hook.

4dd566c9c9 rename Crypto to allmydata.Crypto 
This kind of makes me think that there is a general principle that things
shouldn't know their own names.  After all, a name is what *other* people use
to refer to you.  And in the general case, some other people might refer to you
in ways incompatible with the ways that other people refer to you.

3209fd5e09 rearrange encode/upload, add URIs, switch to ReplicatingEncoder 
Added metadata to the bucket store, which is used to hold the share number
(but the bucket doesn't know that, it just gets a string).

Modified the codec interfaces a bit.

Try to pass around URIs to/from download/upload instead of verifierids.
URI format is still in flux.

Change the current (primitive) file encoder to use a ReplicatingEncoder
because it provides ICodecEncoder. We will be moving to the (less primitive)
file encoder (currently in allmydata.encode_new) eventually, but for now
this change lets us test out PyRS or zooko's upcoming C-based RS codec in
something larger than a single unit test. This primitive file encoder only
uses a single segment, and has no merkle trees.

Also added allmydata.util.deferredutil for a DeferredList wrapper that
errbacks (but only when all component Deferreds have fired) if there were
any errors, which unfortunately is not a behavior available from the standard
DeferredList.

b0315fc549 make encode_new use py_ecc for real live erasure coding 
(This patch is not tested -- I'm working on a Mac which doesn't have gcc
installed...  (gcc is necessary for the crypto module.)  I will now attempt to
connect to a better development computer over my mom's staticy, failure-prone,
14.4 K modem...)

6eaaf1fe9d import py_ecc, a pure python fec by Emin Martinian, which is under a permissive licence 
It is too slow for a real product, but is a quick way to get a working prototype, and also is freely redistributable by us...

3490378551 move all packages into src/, fix allmydata.Crypto build. Now you must perform a 'setup.py build' before using anything, and you must add the build directory (build/lib.linux-i686-2.4) to your PYTHONPATH before doing anything 2006-12-14 03:39:50 -07:00
