This specifies the name of the package using nomdl through godep, which
is applied as a prefix to github.com/attic-labs/noms imports.
For example, -godep=github.com/foo/bar generates imports to
"github.com/foo/bar/Godeps/_workspace/src/github.com/attic-labs/noms".
Instead of writing sequence chunks as soon as they're are created (as a
result of hitting chunk boundaries), only write them once they're
referenced - which only happens if those chunks are themselves chunked.
The effect of this is root chunks of collections/blobs aren't written
until they're committed, which makes the XML importer run twice as fast
on a month of MLB data - 60s instead of 120s, with --ldb-dump-stats
showing a PutCount of 21,272 instead of 342,254.
In the future it should be possible to avoid writing *any* chunks until
the root is committed, which will improve incremental update
performance, but that's a larger change (issue #710). This change fixes
issue #832.
If two files depend on the same file we ended up overwriting the
first written file which is problematic because the "internal" types
would not be written the second time.
Ref values use the TargetRef to get the internal implementation
RegisterFromValFunction and ToNomsValueFromTypeRef were only used by
ref values at this point so these were renamed and simplified to be
more specific for ref values
This is needed to be able to round trip enums.
If there is no codegen for an enum that is read from the datastore we
now return a types.Enum which can be serialized back to the same
sequence.
The generated code for typed structs now uses a Go struct which
implements Value directly. The fields in this struct uses the "user"
type. (The union value still uses types.Value though.)
When a typed struct is created by the decoder, it asks for a struct
builder which returns a channel that the values of the fields of the
struct are sent to.
We now do a recursive call which bottoms out with a ref.Ref for RefKind
Values. This means that we traverse into nested structures consistently.
The effect of this is that we get all the refs that the current chunk
references.
The output file should always be emitted relative to -out-dir. I was
incorrectly appending the path to the input file onto that provided in
-out-dir to construct the path to the output file.
