Merge pull request from GHSA-686w-5m7m-54vc

decNumberToString calls for a buffer that can hold a string of digits+14
characters, not a buffer of size digits+14.
We need to allocate an extra byte for the NUL byte.

-10E-1000010001, for example, will be stringified as -1.0E-1000010000
and decNumberToString will currently write an extra NUL byte after the
allocated buffer in the heap.

jq

jq is a lightweight and flexible command-line JSON processor akin to sed,awk,grep, and friends for JSON data. It's written in portable C and has zero runtime dependencies, allowing you to easily slice, filter, map, and transform structured data.

Documentation

Installation

Prebuilt Binaries

Download the latest releases from the GitHub release page.

Docker Image

Pull the jq image to start quickly with Docker.

Building from source

Dependencies

  • libtool
  • make
  • automake
  • autoconf

Instructions

git submodule update --init # if building from git to get oniguruma
autoreconf -i               # if building from git
./configure --with-oniguruma=builtin
make -j8
make check
sudo make install

Build a statically linked version:

make LDFLAGS=-all-static

If you‘re not using the latest git version but instead building a released tarball (available on the release page), skip the autoreconf step, and flex or bison won’t be needed.

Cross-Compilation

For details on cross-compilation, check out the GitHub Actions file and the cross-compilation wiki page.
