Dev0.4.0 #1381

This used to lead to large refcount numbers, causing Flush to create a lot of IPFS objects, and merkledag to consume tens of gigabytes of RAM. License: MIT Signed-off-by: Jeromy <jeromyj@gmail.com>

OS X sed is documented as "-i SUFFIX", GNU sed as "-iSUFFIX". The one consistent case seems to be "-iSUFFIX", where suffix cannot empty (or OS X will parse the next argument as the suffix). This used to leave around files named `refsout=` on Linux, and was just confusing. License: MIT Signed-off-by: Jeromy <jeromyj@gmail.com>

These secondary copies were never actually queried, and didn't contain the indirect refcounts so they couldn't become the authoritative source anyway as is. New goal is to move pinning into IPFS objects. A migration will be needed to remove the old data from the datastore. This can happen at any time after this commit.

Pinner had method GetManual that returned a ManualPinner, so every Pinner had to implement ManualPinner anyway. License: MIT Signed-off-by: Jeromy <jeromyj@gmail.com>

Platform-dependent behavior is not nice, and negative refcounts are not very useful. License: MIT Signed-off-by: Jeromy <jeromyj@gmail.com>

WARNING: No migration performed! That needs to come in a separate commit, perhaps amended into this one. This is the minimal rewrite, only changing the storage from JSON(+extra keys) in Datastore to IPFS objects. All of the pinning state is still loaded in memory, and written from scratch on Flush. To do more would require API changes, e.g. adding error returns. Set/Multiset is not cleanly separated into a library, yet, as it's API is expected to change radically.

There was doublewrapping with an unneeded msgio. given that we use a stream muxer now, msgio is only needed by secureConn -- to signal the boundaries of an encrypted / mac-ed ciphertext. Side note: i think including the varint length in the clear is actually a bad idea that can be exploited by an attacker. it should be encrypted, too.

The addition of a locking interface to the blockstore allows us to perform atomic operations on the underlying datastore without having to worry about different operations happening in the background, such as garbage collection. License: MIT Signed-off-by: Jeromy <jeromyj@gmail.com>

This commit improves (fixes) the FetchGraph call for recursively fetching every descendant node of a given merkledag node. This operation should be the simplest way of ensuring that you have replicated a dag locally. This commit also implements a method in the merkledag package called EnumerateChildren, this method is used to get a set of the keys of every descendant node of the given node. All keys found are noted in the passed in KeySet, which may in the future be implemented on disk to avoid excessive memory consumption. License: MIT Signed-off-by: Jeromy <jeromyj@gmail.com>

This gives us a clean slate for the new code, avoiding leftovers. License: MIT Signed-off-by: Tommi Virtanen <tv@eagain.net>

Earlier, it also checked checked the leveldb directory. That part added no crash safety to the application, and just hardcoded assumptions about the datastore. If anything, this should rely on the absolute last item created by fsrepo.Init, and there should be fsync guarantees about ordering. License: MIT Signed-off-by: Tommi Virtanen <tv@eagain.net>

To test it, set up an S3 bucket (in an AWS region that is not US Standard, for read-after-write consistency), run `ipfs init`, then edit `~/.ipfs/config` to say "Datastore": { "Type": "s3", "Region": "us-west-1", "Bucket": "mahbukkit", "ACL": "private" }, with the right values. Set `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` in the environment and you should be able to run `ipfs add` and `ipfs cat` and see the bucket be populated. No automated tests exist, unfortunately. S3 is thorny to simulate. License: MIT Signed-off-by: Tommi Virtanen <tv@eagain.net>
