Module lfs_pointer 

Whether a blob is a Git LFS pointer, decided as git-lfs decides it. What: Whether a blob is a Git LFS pointer, decided the way git-lfs 3.8.1 decides it when it scans a push. Why: The upload step finds the LFS objects the pushed commits introduce without starting git-lfs. A blob counts when the scanner would hand it to the transfer queue: smaller than the cutoff (lfs/scanner.go, BlobSizeCutoff), a header that names git-media, hawser or git-lfs (lfs/pointer.go, matcherRE), lines in the order version, oid, size with a known version, an sha256: object name of 64 lower-case hexadecimal digits and a non-negative decimal size; a pointer of size zero is skipped by prepareUpload (commands/uploader.go). The path of the blob and .gitattributes play no part. A spelling the port is not sure about (extension lines, non-ASCII edges) is a decline, so the caller falls back to git-lfs itself.

In TS you’d write (pseudocode):

const verdict = decodePointer(blob); // { kind: 'not-a-pointer' } | { kind: 'pointer', oid, size } | { kind: 'decline' }

Enums

Verdict

What a blob is.

Constants

BLOB_SIZE_CUTOFF

The blob size from which a blob is never read as a pointer.

Functions

decode_pointer

What: The verdict for the content of one blob. Why: One pass over at most BLOB_SIZE_CUTOFF bytes.
