# DragonX utilities

Scripts in this directory are used by DragonX developers in the process of development
or in releasing a new version of DragonX.

Utilities in this directory:

## build.sh

Compile DragonX full node code. This is the main build entrypoint.

## build-arm.sh

Compile DragonX full node code for ARM architecture.
**has not worked for some time**

## build-arm-xcompile.sh

Cross-Compile DragonX full node code for ARM architecture on an x86 build server.

## build-debian-package.sh

Builds an x86 Debian package for DragonX.

## build-debian-package-ARM.sh

Builds an ARM Debian package for DragonX.

## build-mac.sh

Compile DragonX full node code for mac. NOTE: This is likely broken.

## build-win.sh

Compile DragonX full node code for windows

## bootstrap-dragonx.sh

Download and apply a DRAGONX blockchain bootstrap so a new node can sync quickly.
Safely preserves wallet.dat and configuration files, and verifies the archive against
checksums and (once configured) a detached signature. See sign-bootstrap.md for the
signing procedure.

## sign-bootstrap.md

Documentation for maintainers on how to create the signing keypair and sign the
DRAGONX.zip bootstrap archive that bootstrap-dragonx.sh verifies.

## checkpoints.pl

Generate checkpoint data for chainparams.cpp . This automates the creation of
block heights and block hashes by asking dragonxd (via dragonx-cli) for the data
and then generating the C++ code needed to embed them in the DragonX source code.

## docker-entrypoint.sh

Script to use DragonX with Docker.

## docker-hush-cli.sh

Convenience script to run dragonx-cli in a running Docker container.

## replace.pl

Replace a string in a set of files by another string. Very useful for updating
a variable name or value across many files, or updating copyrights.

## 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 util/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

## 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/

When you type "make manpages" it runs this script.

## gen-linux-binary-release.sh

Generate linux release binary.
