This directory contains tools for developers working on this repository.
clang-format-diff.py
===================
A script to format unified git diffs according to [.clang-format](../../src/.clang-format).
For instance, to format the last commit with 0 lines of context,
the script should be called from the git root folder as follows.
```
git diff -U0 HEAD~1.. | ./contrib/devtools/clang-format-diff.py -p1 -i -v
```
copyright\_header.py
====================
Provides utilities for managing copyright headers of `The Bitcoin Core
developers` in repository source files. It has three subcommands:
```
$ ./copyright_header.py report <base_directory> [verbose]
$ ./copyright_header.py update <base_directory>
$ ./copyright_header.py insert <file>
```
Running these subcommands without arguments displays a usage string.
copyright\_header.py report \<base\_directory\> [verbose]
---------------------------------------------------------
Produces a report of all copyright header notices found inside the source files
of a repository. Useful to quickly visualize the state of the headers.
Specifying `verbose` will list the full filenames of files of each category.
copyright\_header.py update \<base\_directory\> [verbose]
---------------------------------------------------------
Updates all the copyright headers of `The Bitcoin Core developers` which were
changed in a year more recent than is listed. For example:
```
// Copyright (c) <firstYear>-<lastYear> The Bitcoin Core developers
```
will be updated to:
```
// Copyright (c) <firstYear>-<lastModifiedYear> The Bitcoin Core developers
```
where `<lastModifiedYear>` is obtained from the `git log` history.
This subcommand also handles copyright headers that have only a single year. In
those cases:
```
// Copyright (c) <year> The Bitcoin Core developers
```
will be updated to:
```
// Copyright (c) <year>-<lastModifiedYear> The Bitcoin Core developers
```
where the update is appropriate.
copyright\_header.py insert \<file\>
------------------------------------
Inserts a copyright header for `The Bitcoin Core developers` at the top of the
file in either Python or C++ style as determined by the file extension. If the
file is a Python file and it has `#!` starting the first line, the header is
inserted in the line below it.
The copyright dates will be set to be `<year_introduced>-<current_year>` where
`<year_introduced>` is according to the `git log` history. If
`<year_introduced>` is equal to `<current_year>`, it will be set as a single
year rather than two hyphenated years.
If the file already has a copyright for `The Bitcoin Core developers`, the
script will exit.
gen-manpages.sh
===============
A small script to automatically create manpages in ../../doc/man by running the release binaries with the -help option.
This requires help2man which can be found at: https://www.gnu.org/software/help2man/
With in-tree builds this tool can be run from any directory within the
repostitory. To use this tool with out-of-tree builds set `BUILDDIR`. For
example:
```bash
BUILDDIR=$PWD/build contrib/devtools/gen-manpages.sh
```
github-merge.py
===============
A small script to automate merging pull-requests securely and sign them with GPG.
For example:
./github-merge.py 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)
Create and verify timestamps of merge commits
---------------------------------------------
To create or verify timestamps on the merge commits, install the OpenTimestamps
client via `pip3 install opentimestamps-client`. Then, dowload the gpg wrapper
`ots-git-gpg-wrapper.sh` and set it as git's `gpg.program`. See
[the ots git integration documentation](https://github.com/opentimestamps/opentimestamps-client/blob/master/doc/git-integration.md#usage)
for further details.
optimize-pngs.py
================
A script to optimize png files in the bitcoin
repository (requires pngcrush).

security-check.py and test-security-check.py
============================================
Perform basic ELF security checks on a series of executables.
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
update-translations.py
======================
Run this script from the root of the repository to update all translations from transifex.
It will do the following automatically:
- fetch all translations
- post-process them into valid and committable format
- add missing translations to the build system (TODO)
See doc/translation-process.md for more information.

circular-dependencies.py
========================
Run this script from the root of the source tree (`src/`) to find circular dependencies in the source code.
This looks only at which files include other files, treating the `.cpp` and `.h` file as one unit.
Example usage:
cd .../src
../contrib/devtools/circular-dependencies.py {*,*/*,*/*/*}.{h,cpp}
