Walkthrough

The recent changes enhance the Tor Docker setup by integrating essential tools and configurations for pluggable transports. Key updates include the installation of dependencies like go, git, ca-certificates, and libcap, along with the creation and building of transport clients such as obfs4proxy, snowflake, and webtunnel. Additionally, support for bridges in Tor's configuration and translations has been added, and the HEALTHCHECK timing has been adjusted for improved stability.

Changes

File/Path	Summary
.github/renovate.json	Added versioning and datasource templates for dependencies obfs4, snowflake, and webtunnel.
tor/Dockerfile	Introduced dependencies go, git, ca-certificates, and libcap. Downloaded and built pluggable transports obfs4proxy, snowflake, and webtunnel. Set capabilities for binding to privileged ports and adjusted the HEALTHCHECK start period.
tor/config.yaml	Introduced the bridges option, now specified as a string with a default empty array [].
tor/translations/en.yaml	Expanded translations to include configuration details for bridges in Tor, with corresponding name and description fields.
tor/.../s6-overlay/s6-rc.d/init-tor/run	Added support for transport plugins (obfs2, obfs3, obfs4, scramblesuit, snowflake, WebTunnel) and included logic to add specified bridges to the Tor configuration file.

In tunnels beneath the moonlight's sheen,
Obfs4proxy and snowflake dream.
With git and go, their tasks they bear,
And webtunnel dances through the night air.
Together they bind, a vigilant guard,
Bridging the gaps, no effort too hard.

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
