From 6a187c065f075c51155873cdb5309105f72f9db6 Mon Sep 17 00:00:00 2001 From: Kevin Atkinson Date: Tue, 19 Apr 2016 17:05:41 -0400 Subject: [PATCH 01/32] Refactor Makefile. Move the go commands that should run under cmd/ipfs in the Makefile in cmd/ipfs rather than doing a "cd cmd/ipfs && go ..." in the root Makefile. The "cd cmd/ipfs && go ..." lines causes problems with GNU Emacs's compilation mode. With the current setup Emacs is unable to jump to the location of the error outputted by go compiler as it can not find the source file. The problem is that the embedded "cd" command causes Emacs's compilation mode to lose track of the current directory and thus attempts to look for the source file in the wrong directory.

The datastore has an optional "advanced" datastore that handles Put requests for non []byte values, a "normal" datastore that handles all other put requests, and then any number of other datastore, some of them that can be designated read-only. Delete requests are passed on to all datastore not designed read-only. For now, querying will only work on a "normal" datastore. Note: Only tested in the case of just a "normal" datastore and the case of an "advanced" and "normal" datastore. Towards #875.

This involved: 1) Constructing an alternative data object that instead of raw bytes is a DataPtr with information on where the data is on the file system and enough other information in AltData to reconstruct the Merkle-DAG node. 2) A new datastore "filestore" that stores just the information in DataPtr. When retrieving blocks the Merkle-DAG node is reconstructed from combining AltData with the data from the file in the file system. Because the datastore needs to reconstruct the node it needs access to the Protocol Buffers for "merkledag" and "unixfs" and thus, for now, lives in go-ipfs instead of go-datastore. The filestore uses another datastore to store the protocol buffer encoded DataPtr. By default this is the leveldb datastore, as the size fo the encoded DataPtr is small. Towards #875.
