Unlike RFC 1951 (DEFLATE), bzip2 does not use zero-length Huffman codes to indicate that the symbol is missing. Instead, bzip2 uses a sparse bitmap to indicate which symbols are present. Thus, it is undefined what happens when a length of zero is used. Thus, fix the parsing logic so that the length cannot ever go below 1-bit similar to how the C logic does things. To confirm that the C bzip2 utility chokes on this data: $ echo "425a6836314159265359b1f7404b000000400040002000217d184682ee48 a70a12163ee80960" | xxd -r -p | bzip2 -d bzip2: Data integrity error when decompressing For reference see: bzip2-1.0.6/decompress.c:320 Change-Id: Ic1568f8e7f80cdea51d887b4d712cc239c2fe85e Reviewed-on: https://go-review.googlesource.com/20119 Run-TryBot: Joe Tsai <joetsai@digital-static.net> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Matthew Dempsky <mdempsky@google.com> |

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.
Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
