Flow of TAR stream
|
|
==================
|
|
|
|
The underlying use of `github.com/vbatts/tar-split/archive/tar` is most similar
|
|
to stdlib.
|
|
|
|
|
|
Packer interface
|
|
----------------
|
|
|
|
For ease of storage and usage of the raw bytes, there will be a storage
|
|
interface, that accepts an io.Writer (This way you could pass it an in memory
|
|
buffer or a file handle).
|
|
|
|
Having a Packer interface can allow configuration of hash.Hash for file payloads
|
|
and providing your own io.Writer.
|
|
|
|
Instead of having a state directory to store all the header information for all
|
|
Readers, we will leave that up to user of Reader. Because we can not assume an
|
|
ID for each Reader, and keeping that information differentiated.
|
|
|
|
|
|
|
|
State Directory
|
|
---------------
|
|
|
|
Perhaps we could deduplicate the header info, by hashing the rawbytes and
|
|
storing them in a directory tree like:
|
|
|
|
./ac/dc/beef
|
|
|
|
Then reference the hash of the header info, in the positional records for the
|
|
tar stream. Though this could be a future feature, and not required for an
|
|
initial implementation. Also, this would imply an owned state directory, rather
|
|
than just writing storage info to an io.Writer.
