pull-git-pack

Encode and decode git packfiles, with a pull-stream API

API

var pack = require('pull-git-pack')

pack.decode(opts, repo[, onEnd, read]): readObject

Transform packfile data into git objects. If read is not given, pack.decode returns a through stream.

• opts.verbosity < 2: number, determines level of console output.

  • verbosity < 2: number, determines level of console output.
  • verbosity == 2: number, determines level of console output.
  • verbosity > 2: number, determines level of console output.

• opts.onHeader(numObjects): function called once when reading the header at the beginning of the packfile that lists how many objects the packfile contains.

• repo: an abstract-pull-git-repo object. repo.getObject may be called to resolve ref-deltas in the packfile (including if the target object is in the packfile itself)

• onEnd(err): function called when the packfile is finished decoding or has an error

• read: readable stream of packfile data

• readObject: readable stream of git objects in the format of abstract-pull-git-repo

  • object.type: one of ["tag", "commit", "tree", "blob"]
  • object.length: size in bytes of the object
  • object.offset: offset of the object in the pack. for use with packidxs
  • object.read(abort, next(end, buf)): readable stream of data

pack.decodeWithIndex(repo, readPack, readIdx): readObject

Transform a packfile data into git objects, using pack index data to speed up the process.

pack.encode([opts, ]numObjects, readObject): read

Transform git objects into packfile data. If readObject is not given, pack.encode returns a through stream.

• opts: options, reserved for later use

• numObjects: number of git objects that will be in the packfile

• readObject(end, cb(end, object)}: readable stream of git objects

• read(end, cb(end, data)): readable stream of packfile data

Index Pack

var indexPack = require('pull-git-pack/lib/index-pack')

indexPack(cb(err, idx, packfileFixed)) : sink

Build a pack index (.idx file) from a git pack file, as git-index-pack(1) would do.

• source: stream of packfile data
• idx: readable stream of pack index data
• packfileFixed: stream of pack data, fixed to make it not thin
