Ricochet-Refresh Build
=================
Installing build dependencies
-----------------------------
To build Ricochet-Refresh, you need a Linux distribution that has support
for runc (such as Debian Buster, Ubuntu 16.04, Fedora 30, etc ...).
Your user account should have sudo access, which is required to be able
to extract container file systems, start containers and copy files to and
from containers.
The sources of most components are downloaded using git, which needs to
be installed. Some components are downloaded using mercurial which also
needs to be installed.
You also need a few perl modules installed:
- YAML::XS
- File::Basename
- Getopt::Long
- Template
- IO::Handle
- IO::CaptureOutput
- JSON
- File::Temp
- Path::Tiny
- File::Path
- File::Slurp
- File::Copy::Recursive
- String::ShellQuote
- Sort::Versions
- Digest::SHA
- Data::UUID
- Data::Dump
If you are running Debian or Ubuntu, you can install them with:
# apt-get install libyaml-libyaml-perl libtemplate-perl \
libio-handle-util-perl libio-all-perl \
libio-captureoutput-perl libjson-perl libpath-tiny-perl \
libstring-shellquote-perl libsort-versions-perl \
libdigest-sha-perl libdata-uuid-perl libdata-dump-perl \
libfile-copy-recursive-perl libfile-slurp-perl git runc \
mercurial
The build system is based on rbm, which is included as a git submodule
in the rbm/ directory. You can fetch the rbm git submodule by running
'make submodule-update'.
Starting a build
----------------
To start a build, run one of the following commands, depending on the
channel you want to build:
$ make release
$ make nightly
You can find the build result in the directory release/unsigned/$version
or alpha/unsigned/$version for release or alpha builds. The result of
nightly can be found in the nightly/$version directory.
If you want to build for a specific platform only, append the platform
name to the makefile target:
$ make nightly-linux-x86_64
$ make nightly-linux-i686
$ make nightly-windows-i686
$ make nightly-windows-x86_64
$ make nightly-osx-x86_64
When you want to quickly do a build to test a change, you can use the
testbuild makefile target, and find the build in the testbuild directory.
The build will be the same as regular alpha builds, except that in order
to make the build faster, only the en-US locale will be built, and no
mar file will be created. If you want to base your testbuild on the latest
nightly code insted, rename rbm.local.conf.example to rbm.local.conf
and adapt the torbrowser-testbuild option accordingly.
Updating git sources
--------------------
You can run `make fetch` to fetch the latest sources from git for all
components included in Ricochet-Refresh. You should run this if you want to
make a nightly build with the latest commits, and you disabled automatic
fetching of new commits for nightly builds in rbm.local.conf.
Number of make processes
------------------------
By default the builds are run with 4 processes simultaneously (with
make -j4). If you want to change the number of processes used, you can
set the RBM_NUM_PROCS environment variable:
$ export RBM_NUM_PROCS=8
You can also set the buildconf/num_procs option in rbm.local.conf.
Automated builds
----------------
If the build fails, a shell will automatically open in the build
container to help you debug the problem. You probably want to disable
this if you want to do automated builds. To disable this, set
the RBM_NO_DEBUG environment variable to 1:
export RBM_NO_DEBUG=1
Or set the debug option to 0 in the rbm.local.conf file.
If you want to select the output directory, you can use rbm's --output-dir
option. You can look at the Makefile to find the rbm command for what
you want to build, and add the --output-dir option. For example, if you
want to build Ricochet-Refresh nightly for linux-x86_64:
./rbm/rbm build release --output-dir=/var/builds/nightly/2020-05-23 \
--target nightly --target torbrowser-linux-x86_64
The files will be put in the directory selected by --output-dir in a
subdirectory named as the version number (or current date for nightly).
To remove this version subdirectory, add the noversiondir target:
./rbm/rbm build release --output-dir=/var/builds/nightly/2020-05-23 \
--target nightly --target torbrowser-linux-x86_64 \
--target noversiondir
Signing builds
--------------
If the environment variable RBM_SIGN_BUILD is set to 1, the
sha256sums-unsigned-build.txt and sha256sums-unsigned-build.incrementals.txt
files will be signed with gpg. You can use the RBM_GPG_OPTS environment
variable to add some options to the gpg command used to sign the file.
You can also set the var/sign_build and var/sign_build_gpg_opts options
in the rbm.local.conf file.
Cleaning obsolete files and containers images
---------------------------------------------
You can run `make clean` to clean old build files and containers that
are no longer used in current builds. Before doing that, you need to
configure the branches and build targets you are using in the
rbm.local.conf file. The cleaning script will check out all the configured
branches to create a list of used build files, and delete the files
from the 'out' directory that are not used. If you want to see the list
of files and containers that would be removed without doing it, you can
use `make clean-dry-run`.
