Tamás Gulácsi 97520583b8 Use 'uint32' instead of 'int64' for blob sizes everywhere.
Not just in blob.SizedRef, but in blobserver.Fetch and
blobserver.FetchStreaming, too.
Blobs have a max size of 10-32 MB anyway, and the index.Corpus is now using
uint32 to save memory.

Brad Fitzpatrick 70475701d1 Get rid of QueueCreator and all its associated complexity.
Previous TODO entry was:

-- Get rid of QueueCreator entirely. Plan:
     -- sync handler still has a source and dest (one pair) but
        instead of calling CreateQueue on the source, it instead
        has an index.Storage (configured via a RequiredObject
        so it can be a kvfile, leveldb, mysql, postgres etc)
     -- make all the index.Storage types be instantiable
        from a jsonconfig Object, perhaps with constructors keyed
        on a "type" field.
     -- make sync handler support blobserver.Receiver (or StatReceiver)
        like indexes, so it can receive blobs.  but all it needs to
        do to acknowledge the ReceiveBlob is write and flush to its
        index.Storage. the syncing is async by default. (otherwise callers
        could just use "replica" if they wanted sync replication).
        But maybe for ease of configuration switching, we could also
        support a sync mode.  when it needs to replicate a blob,
        it uses the source.
     -- future option: sync mirror to an alternate path on ReceiveBlob
        that can delete. e.g. you're uploading to s3 and google,
        but don't want to upload to both at once, so you use the localdisk
        as a buffer to spread out your upstream bandwidth.
     -- end result: no more hardlinks or queue creator.

Tamás Gulácsi 161fc061d3 use syncutil.Group and syncutil.Gate for paralellizing blobserver stats/removes
- where TODO exist.

Brad Fitzpatrick 7dd7f948cc localdisk: fix Stat deadlock regression, use pkg/gate.
The errc channel needs to be buffered. Broken by b24cad68dd which
radically simplified this method.

Brad Fitzpatrick b24cad68dd Cleanup: remove BlobHub and time.Duration waits from storage interface
Move up a layer to the HTTP.  Also, start to remove ContextWrapper
stuff.  We've done it differently for App Engine instead, and will do
it differently yet moving forward.

Also add blobserver.Receive and use it in most places, moving checksum
verification up a layer.

Bunch of other cleanup and TODO fixing too.

Much simpler and cleaner.

Brad Fitzpatrick 0714a463c9 Update from r60 to [almost] Go 1.
A lot is still broken, but most stuff at least compiles now.

The directory tree has been rearranged now too.  Go libraries are now
under "pkg".  Fully qualified, they are e.g. "camlistore.org/pkg/jsonsign".

The go tool cannot yet fetch from arbitrary domains, but discussion is
happening now on which mechanism to use to allow that.

For now, put the camlistore root under $GOPATH/src.  Typically $GOPATH
is $HOME, so Camlistore should be at $HOME/src/camlistore.org.

Then you can:

$ go build ./server/camlistored

... etc

The build.pl script is currently disabled.  It'll be resurrected at
some point, but with a very different role (helping create a fake
GOPATH and running the go build command, if things are installed at
the wrong place, and/or running fileembed generators).

Many things are certainly broken.

Many things are disabled.  (MySQL, all indexing, etc).

Many things need to be moved into
camlistore.org/third_party/{code.google.com,github.com} and updated
from their r60 to Go 1 versions, where applicable.

The GoMySQL stuff should be updated to use database/sql and the ziutek
library implementing database/sql/driver.

Help wanted.
