Overview ¶
Package blob handles content-addressed blob storage in Fossil repository databases.
Fossil's blob format is a 4-byte big-endian uncompressed-size prefix followed by zlib-compressed data. Compress and Decompress handle this encoding transparently.
Store compresses content, computes its SHA1 hash, and inserts it into the blob table. StoreDelta does the same for delta-encoded blobs and records the delta relationship. Load retrieves and decompresses a blob by RID.

Functions ¶
func Compress ¶
Compress produces Fossil-compatible compressed blob content: [4-byte big-endian uncompressed size][zlib-compressed data]. This matches Fossil's blob_compress() in src/blob.c.
func Decompress ¶
Decompress handles Fossil's compressed blob format: [4-byte big-endian uncompressed size][zlib-compressed data]. The 4-byte prefix is skipped before decompressing.
func StoreDelta ¶
