I am very fond of this patch. Still, the fact remains that until this
command is implemented by some other fast-import backend, it is hard
to know what git-specific concepts are encoded in its current
implementation. (I am in particular worried about what should be
gauranteed about the blob_identifier in the
blob blob_identifier 1823
line and whether
cat-blob blob_name
cat-blob :11
are going to overlap and cause trouble for some backends.)
On the other hand, development of svn-fe continues to benefit from
cat-blob and its cousins ls-tree and ls[1]. and there has been brief
discussion of using cat-blob to make cvs2git more friendly. So here's
a reroll, since it seems clear that this feature should be in future
versions of fast-import in some form.
Thoughts welcome, as always (even as simple as "I have a bad feeling
about this" or "everything in this patch looks ready to go").
Patches based against v1.7.0.7 for no particular reason.
David Barr (1):
fast-import: let importers retrieve blobs
Jonathan Nieder (3):
fast-import: stricter parsing of integer options
fast-import: clarify documentation of "feature" command
fast-import: Allow cat-blob requests at arbitrary points in stream

[1] ls-tree commit_name "path/to/file" would have output format
100644 blob blob_identifier path/to/file and within a commit
command, ls "path/to/file" would produce output in the same
format.
