Push notification - Package manifest format

[miroslavhajek]

1. What version of Go are you using (go version)?

• go version go1.12.7 darwin/amd64
• github.com/RobotsAndPencils/buford v0.14.0

2. What operating system (GOOS) are you using (go env) and what version?

3. What did you do? (steps to reproduce or a code sample is helpful)

Create package for Apple notification via

pkg := pushpackage.New(c.Response().Writer)
pkg.EncodeJSON("website.json", ...)
pkg.File("icon.iconset/icon_16x16.png", "static/icon_16x16.png")
pkg.File("icon.iconset/[email protected]", "static/[email protected]")
err := pkg.Sign(...) // err = nil, OK

4. What did you expect to see?

The manifest is a JSON dictionary named manifest.json that contains an entry for each file, where the local file path is the entry’s key, and a dictionary object is the entry’s value. This dictionary contains the hashType and hashValue, which is the file’s SHA512 checksum; for example:

{
   "website.json": {
      "hashType": "sha512",
      "hashValue": "..."
   },
   "icon.iconset/icon_16x16.png": {
      "hashType": "sha512",
      "hashValue": "8bb462e25ca79cca241355f5ae97ffab352acf7d2a0390f6547f1d0a55ade59e01e725bea70778ad2822b1ec137a8c0547197727ae2e9fed620b0d3ddea6803b"
   },
   ...
}

5. What did you see instead?

{
  "icon.iconset/icon_16x16.png": "da39a3ee5e6b4b0d3255bfef95601890afd80709",
  "icon.iconset/[email protected]": "da39a3ee5e6b4b0d3255bfef95601890afd80709",
  "website.json": "..."
}

Response from Apple on {webServiceURL}/v1/log API:

{"logs":["Unable to generate ICNS file for push notification package"]}

In [email protected]/pushpackage/pushpackage.go in only simple hastable and the checksum is sha1 algorithm instead of sha512 ([email protected]/pushpackage/checksum.go).

package pushpackage

// Package for website push package or wallet pass package.
type Package struct {
	z *zip.Writer

	// manifest is a map of relative file paths to their SHA checksums
	manifest map[string]string

	err error
}
