René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Gzip decoder too strict","articleBody":"- **Version**: 5.9.0\n- **Platform**: Windows 7 64 bit\n- **Subsystem**: zlib\n\nWhile talking to a web server on an embedded device, asking for gzip content encoding I get responses that are considered OK by all major browsers (Chrome, Firefox, IE) and also cURL. However, the Node `zlib`module considers the gzip stream incomplete and throws an error. The error returned by the `zlib` module reads: `Error: unexpected end of file at Zlib._handle.onerror (zlib.js:363:17)`. Inspecting the gzip response it seems to be missing a footer detailing the CRC and the length of the compressed data.\n\nA small program that reproduces this with an actual response from the device in it:\n\n``` javascript\nvar buffer = require(\"buffer\");\nvar stream = require(\"stream\");\nvar fs = require(\"fs\");\nvar zlib = require(\"zlib\");\n\nvar s = new stream.Readable();\nvar b = new buffer.Buffer([\n    0x1F, 0x8B, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x0B, 0xB2, 0xB1,\n    0xAF, 0xC8, 0xCD, 0x51, 0x28, 0x4B, 0x2D, 0x2A, 0xCE, 0xCC, 0xCF, 0xB3,\n    0x55, 0x32, 0xD4, 0x33, 0x50, 0x52, 0x48, 0xCD, 0x4B, 0xCE, 0x4F, 0xC9,\n    0xCC, 0x4B, 0xB7, 0x55, 0x2A, 0x2D, 0x49, 0xD3, 0xB5, 0x50, 0x52, 0xB0,\n    0xB7, 0xE3, 0xE5, 0xB2, 0x49, 0xCC, 0x49, 0x2C, 0xCA, 0x2D, 0x56, 0x48,\n    0x4E, 0x4C, 0xCE, 0x48, 0xCD, 0x4C, 0xB1, 0x55, 0xB2, 0x54, 0x52, 0x50,\n    0xD0, 0x07, 0x4A, 0x00, 0x00, 0x00, 0x00, 0xFF, 0xFF\n]);\n\ns.push(b);\ns.push(null);\ns.pipe(zlib.createGunzip()).pipe(process.stdout);\n```\n\nWould it be possible to make the Node gzip decoder more lenient and behave more like all major browsers and cURL do?\n","author":{"url":"https://github.com/peterkooijmans","@type":"Person","name":"peterkooijmans"},"datePublished":"2016-03-17T16:31:10.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":4},"url":"https://github.com/5761/node/issues/5761"}
