tdurieux 9adff11e74 fix(cache): atomic file writes and size-validated cache reads
A failed/interrupted GitHub fetch could leave a 0-byte or truncated
file in the local cache. Subsequent reads happily streamed the empty
content as the file's body — visible to users as an "Empty file" with
HTTP 200. Reproduced on artifact-70B6/Lethe/configs.py (#694).

- FileSystem.write: stream into a sibling .tmp and rename into place
  only on finish. Stream errors discard the tmp and leave any prior
  cached file untouched. Drop the utf-8 encoding that was silently
  corrupting binary blobs.
- GitHubStream.getFileContentCache: accept an expected size and treat
  cached.size < expected as a poisoned cache (truncated fetch) → rm
  and re-fetch. cached.size >= expected is accepted, which keeps
  Git LFS-resolved files (whose FileModel.size is the pointer size)
  working.
- AnonymizedFile: expose size() and pass it through to the streamer
  alongside sha so the cache check has the upstream size.

Existing poisoned entries self-heal on next access.

Anonymous Github

Anonymous Github is a system that helps anonymize Github repositories for double-anonymous paper submissions. A public instance of Anonymous Github is hosted at https://anonymous.4open.science/.

Anonymous Github anonymizes the following:

  • Github repository owner, organization, and name
  • File and directory names
  • File contents of all extensions, including markdown, text, Java, etc.

Usage

Public instance

https://anonymous.4open.science/

CLI

This CLI tool allows you to anonymize your GitHub repositories locally, generating an anonymized zip file based on your configuration settings.

# Install the Anonymous GitHub CLI tool
npm install -g @tdurieux/anonymous_github

# Run the Anonymous GitHub CLI tool
anonymous_github

Own instance

1. Clone the repository

git clone https://github.com/tdurieux/anonymous_github/
cd anonymous_github
npm i

2. Configure the GitHub token

Create a .env file with the following contents:

GITHUB_TOKEN=<GITHUB_TOKEN>
CLIENT_ID=<CLIENT_ID>
CLIENT_SECRET=<CLIENT_SECRET>
PORT=5000
DB_USERNAME=
DB_PASSWORD=
AUTH_CALLBACK=http://localhost:5000/github/auth,

3. Start Anonymous Github server

docker-compose up -d

4. Go to Anonymous Github

Go to http://localhost:5000. By default, Anonymous Github uses port 5000. It can be changed in docker-compose.yml. I would recommand to put Anonymous GitHub behind ngnix to handle the https certificates.

What is the scope of anonymization?

In double-anonymous peer-review, the boundary of anonymization is the paper plus its online appendix, and only this, it's not the whole world. Googling any part of the paper or the online appendix can be considered as a deliberate attempt to break anonymity (explanation)

How does it work?

Anonymous Github either downloads the complete repository and anonymizes the content of the file or proxies the request to GitHub. In both cases, the original and anonymized versions of the file are cached on the server.

gitmask is a tool to anonymously contribute to a Github repository.

blind-reviews is a browser add-on that enables a person reviewing a GitHub pull request to hide identifying information about the person submitting it.
