Building OnionShare

Start by getting the source code:

git clone https://github.com/micahflee/onionshare.git
cd onionshare

Linux

Install the needed dependencies:

For Debian-like distros:

apt install -y python3-flask python3-stem python3-pyqt5 python3-crypto python3-socks  python-nautilus tor obfs4proxy python3-pytest build-essential fakeroot python3-all python3-stdeb dh-python python3-flask-httpauth python3-distutils python3-psutil python3-watchdog

For Fedora-like distros:

dnf install -y python3-flask python3-flask-httpauth python3-stem python3-qt5 python3-crypto python3-pysocks nautilus-python tor obfs4 python3-pytest rpm-build python3-psutil python3-watchdog

After that you can try both the CLI and the GUI version of OnionShare:

./dev_scripts/onionshare
./dev_scripts/onionshare-gui

You can also build OnionShare packages to install:

Create a .deb on Debian-like distros: ./install/build_deb.sh

Create a .rpm on Fedora-like distros: ./install/build_rpm.sh

For OpenSuSE: There are instructions for building in the wiki.

For ArchLinux: There is a PKBUILD available here that can be used to install OnionShare.

If you find that these instructions don't work for your Linux distribution or version, consult the Linux Distribution Support wiki guide, which might contain extra instructions.

macOS

Install Xcode from the Mac App Store. Once it's installed, run it for the first time to set it up. Also, run this to make sure command line tools are installed: xcode-select --install. And finally, open Xcode, go to Preferences > Locations, and make sure under Command Line Tools you select an installed version from the dropdown. (This is required for installing Qt5.)

Download and install Python 3.7.4 from https://www.python.org/downloads/release/python-374/. I downloaded python-3.7.4-macosx10.9.pkg.

You may also need to run the command /Applications/Python\ 3.7/Install\ Certificates.command to update Python 3.6's internal certificate store. Otherwise, you may find that fetching the Tor Browser .dmg file fails later due to a certificate validation error.

Install Qt 5.13.1 for macOS from https://www.qt.io/offline-installers. I downloaded qt-opensource-mac-x64-5.13.1.dmg. In the installer, you can skip making an account, and all you need is Qt > Qt 5.13.1 > macOS.

Now install pip dependencies. If you want to use a virtualenv, create it and activate it first:

python3 -m venv venv
. venv/bin/activate

Then install the dependencies:

pip3 install -r install/requirements.txt

You can run both the CLI and GUI versions of OnionShare without building an bundle

./dev_scripts/onionshare
./dev_scripts/onionshare-gui

To build the app bundle

install/build_osx.sh

Now you should have dist/OnionShare.app.

To codesign and build a pkg for distribution

install/build_osx.sh --release

Now you should have dist/OnionShare.pkg.

Windows

Setting up your dev environment

Download Python 3.7.4, 32-bit (x86) from https://www.python.org/downloads/release/python-374/. I downloaded python-3.7.4.exe. When installing it, make sure to check the "Add Python 3.7 to PATH" checkbox on the first page of the installer.

Open a command prompt, cd to the onionshare folder, and install dependencies with pip:

pip install -r install\requirements.txt

Install the Qt 5.13.1 from https://www.qt.io/offline-installers. I downloaded qt-opensource-windows-x86-5.13.1.exe. In the installer, you can skip making an account, and all you need Qt > Qt 5.13.1 > MSVC 2017 32-bit.

After that you can try both the CLI and the GUI version of OnionShare:

python dev_scripts\onionshare
python dev_scripts\onionshare-gui

If you want to build a .exe

These instructions include adding folders to the path in Windows. To do this, go to Start and type "advanced system settings", and open "View advanced system settings" in the Control Panel. Click Environment Variables. Under "System variables" double-click on Path. From there you can add and remove folders that are available in the PATH.

Download and install 7-Zip from http://www.7-zip.org/download.html. I downloaded 7z1900.exe.

Download and install the standalone Windows 10 SDK. Note that you may not need this if you already have Visual Studio.

Add the following directories (you might want to make sure these are exact on your computer) to the path:

  • C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x86
  • C:\Program Files (x86)\Windows Kits\10\Redist\10.0.18362.0\ucrt\DLLs\x86
  • C:\Program Files (x86)\7-Zip
  • C:\Users\user\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\PyQt5\Qt\bin

If you want the .exe to not get falsely flagged as malicious by anti-virus software

OnionShare uses PyInstaller to turn the python source code into Windows executable .exe file. Apparently, malware developers also use PyInstaller, and some anti-virus vendors have included snippets of PyInstaller code in their virus definitions. To avoid this, you have to compile the Windows PyInstaller bootloader yourself instead of using the pre-compiled one that comes with PyInstaller.

(If you don't care about this, you can install PyInstaller with pip install PyInstaller==3.5.)

Here's how to compile the PyInstaller bootloader:

Download and install Microsoft Build Tools for Visual Studio 2019. I downloaded vs_buildtools__1285639570.1568593053.exe. In the installer, check the box next to "Visual C++ build tools". Click "Individual components", and under "Compilers, build tools and runtimes", check "Windows Universal CRT SDK". Then click install. When installation is done, you may have to reboot your computer.

Then, enable the 32-bit Visual C++ Toolset on the Command Line like this:

cd "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build"
vcvars32.bat

Make sure you have a new enough setuptools:

pip install --upgrade setuptools

Now make sure you don't have PyInstaller installed from pip:

pip uninstall PyInstaller
rmdir C:\Users\user\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\PyInstaller /S

Change to a folder where you keep source code, and clone the PyInstaller git repo and checkout the v3.5 tag:

git clone https://github.com/pyinstaller/pyinstaller.git
cd pyinstaller
git tag -v v3.5

(Note that ideally you would verify the git tag, but the PGP key that has signed the v3.5 git tag for is not published anywhere, so this isn't possible. See this issue.)

And compile the bootloader, following these instructions. To compile, run this:

cd bootloader
python waf distclean all --target-arch=32bit --msvc_targets=x86

Finally, install the PyInstaller module into your local site-packages:

cd ..
python setup.py install

Now the next time you use PyInstaller to build OnionShare, the .exe file should not be flagged as malicious by anti-virus.

If you want to build the installer

If you want to sign binaries with Authenticode

  • You'll need a code signing certificate. I got an open source code signing certificate from Certum.
  • Once you get a code signing key and certificate and covert it to a pfx file, import it into your certificate store.

To make a .exe:

  • Open a command prompt, cd into the onionshare directory, and type: pyinstaller install\pyinstaller.spec. onionshare-gui.exe and all of their supporting files will get created inside the dist folder.

To build the installer:

Note that you must have a codesigning certificate installed in order to use the install\build_exe.bat script, because it codesigns onionshare-gui.exe, uninstall.exe, and onionshare-setup.exe.

Open a command prompt, cd to the onionshare directory, and type: install\build_exe.bat

This will prompt you to codesign three binaries and execute one unsigned binary. When you're done clicking through everything you will have dist\onionshare-setup.exe.

Running tests

OnionShare includes PyTest unit tests. To run the tests, first install some dependencies:

pip3 install -r install/requirements-tests.txt

Then you can run pytest against the tests/ directory.

pytest tests/

You can run GUI tests like this:

pytest --rungui tests/

If you would like to also run the GUI unit tests in 'tor' mode, start Tor Browser in the background, then run:

pytest --rungui --runtor tests/

Keep in mind that the Tor tests take a lot longer to run than local mode, but they are also more comprehensive.

You can also choose to wrap the tests in xvfb-run so that a ton of OnionShare windows don't pop up on your desktop (you may need to install the xorg-x11-server-Xvfb package), like this:

xvfb-run pytest --rungui tests/

Making releases

This section documents the release process. Unless you're a core OnionShare developer making a release, you'll probably never need to follow it.

Changelog, version, and signed git tag

Before making a release, all of these should be complete:

  • share/version.txt should have the correct version
  • install/onionshare.nsi should have the correct version, for the Windows installer
  • CHANGELOG.md should be updated to include a list of all major changes since the last release
  • There must be a PGP-signed git tag for the version, e.g. for OnionShare 2.1, the tag must be v2.1

The first step for the Linux, macOS, and Windows releases is the same:

Verify the release git tag:

git fetch
git tag -v v$VERSION

If the tag verifies successfully, check it out:

git checkout v$VERSION

Linux release

TODO: Write Flatpak instructions (see this issue).

To make a PPA release:

  • Go to Ubuntu build machine, which must have ~/.dput.cf with the correct PPA info in it, and with the correct PGP signing key
  • Verify and checkout the git tag for this release
  • Run ./install/ppa_release.sh, which builds a source package and uploads to the PPA build server
  • Login to Launchpad to monitor the build and make sure it is successful; if not, make minor patches and try the release again
  • After build is successful, from Launchpad, copy the binary from cosmic into other suites

macOS release

To make a macOS release, go to macOS build machine:

  • Build machine should be running macOS 10.11.6, and must have the Apple-trusted Developer ID Application: Micah Lee and Developer ID Installer: Micah Lee code-signing certificates installed
  • Verify and checkout the git tag for this release
  • Run ./install/build_osx.sh --release; this will make a codesigned installer package called dist/OnionShare-$VERSION.pkg
  • Copy OnionShare-$VERSION.pkg to developer machine

Then move back to the developer machine:

  • PGP-sign the macOS installer, gpg -a --detach-sign OnionShare-$VERSION.pkg

Note that once we support notarizing the macOS installer (see this issue), these will be the steps instead:

  • Developer machine, running the latest macOS, must have an app-specific Apple ID password saved in the login keychain called onionshare-notarize
  • Notarize it: xcrun altool --notarize-app --primary-bundle-id "com.micahflee.onionshare" -u "micah@micahflee.com" -p "@keychain:onionshare-notarize" --file OnionShare-$VERSION.pkg
  • Wait for it to get approved, check status with: xcrun altool --notarization-history 0 -u "micah@micahflee.com" -p "@keychain:onionshare-notarize"
  • After it's approved, staple the ticket: xcrun stapler staple OnionShare-$VERSION.pkg
  • PGP-sign the final, notarized and stapled, gpg -a --detach-sign OnionShare-$VERSION.pkg

This process ends up with two final files:

OnionShare-$VERSION.pkg
OnionShare-$VERSION.pkg.asc

Windows release

To make a Windows release, go to Windows build machine:

  • Build machine should be running Windows 10, and have the Windows codesigning certificate installed
  • Verify and checkout the git tag for this release
  • Run install\build_exe.bat; this will make a codesigned installer package called dist\onionshare-$VERSION-setup.exe
  • Copy onionshare-$VERSION-setup.exe to developer machine

Then move back to the developer machine:

  • PGP-sign the Windows installer, gpg -a --detach-sign onionshare-$VERSION-setup.exe

This process ends up with two final files:

onionshare-$VERSION-setup.exe
onionshare-$VERSION-setup.exe.asc

Source package

To make a source package, run ./install/build_source.sh $TAG, where $TAG is the the name of the signed git tag, e.g. v2.1.

This process ends up with two final files in dist:

onionshare-$VERSION.tar.gz
onionshare-$VERSION.tar.gz.asc

Publishing the release

To publish the release:

  • Create a new release on GitHub, put the changelog in the description of the release, and upload all six files (the macOS installer, the Windows installer, the source package, and their signatures)
  • Upload the six release files to https://onionshare.org/dist/$VERSION/
  • Copy the six release files into the OnionShare team Keybase filesystem
  • Update the onionshare-website repo:
    • Edit latest-version.txt to match the latest version
    • Update the version number and download links
    • Deploy to https://onionshare.org/
  • Email the onionshare-dev mailing list announcing the release
  • Make a PR to homebrew-cask to update the macOS version
