Contents

This directory contains tools for developers working on this repository.

github-merge.sh

A small script to automate merging pull-requests securely and sign them with GPG.

For example:

./github-merge.sh bitcoin/bitcoin 3077

(in any git repository) will help you merge pull request #3077 for the bitcoin/bitcoin repository.

What it does:

  • Fetch master and the pull request.
  • Locally construct a merge commit.
  • Show the diff that merge results in.
  • Ask you to verify the resulting source tree (so you can do a make check or whatever).
  • Ask you whether to GPG sign the merge commit.
  • Ask you whether to push the result upstream.

This means that there are no potential race conditions (where a pullreq gets updated while you're reviewing it, but before you click merge), and when using GPG signatures, that even a compromised github couldn't mess with the sources.

Setup

Configuring the github-merge tool for the bitcoin repository is done in the following way:

git config githubmerge.repository bitcoin/bitcoin
git config githubmerge.testcmd "make -j4 check" (adapt to whatever you want to use for testing)
git config --global user.signingkey mykeyid (if you want to GPG sign)

fix-copyright-headers.py

Every year newly updated files need to have its copyright headers updated to reflect the current year. If you run this script from src/ it will automatically update the year on the copyright header for all .cpp and .h files if these have a git commit from the current year.

For example a file changed in 2014 (with 2014 being the current year): // Copyright (c) 2009-2013 The Bitcoin developers

would be changed to: // Copyright (c) 2009-2014 The Bitcoin developers

symbol-check.py

A script to check that the (Linux) executables produced by gitian only contain allowed gcc, glibc and libstdc++ version symbols. This makes sure they are still compatible with the minimum supported Linux distribution versions.

Example usage after a gitian build:

find ../gitian-builder/build -type f -executable | xargs python contrib/devtools/symbol-check.py

If only supported symbols are used the return value will be 0 and the output will be empty.

If there are 'unsupported' symbols, the return value will be 1 a list like this will be printed:

.../64/test_bitcoin: symbol memcpy from unsupported version GLIBC_2.14
.../64/test_bitcoin: symbol __fdelt_chk from unsupported version GLIBC_2.15
.../64/test_bitcoin: symbol std::out_of_range::~out_of_range() from unsupported version GLIBCXX_3.4.15
.../64/test_bitcoin: symbol _ZNSt8__detail15_List_nod from unsupported version GLIBCXX_3.4.15
