== Clock skew testing == ## Clock skew testing
The faketime package in Ubuntu 16.04 is too old to know about `CLOCK_MONOTONIC_COARSE` but tor uses it. This causes startup to fail in the faketime library. Also if asan is active, its runtime must be listed first in `LD_PRELOAD`, which prevents using the normal faketime wrapper script.

== GitLab and GitHub repo sync notes == ## GitLab and GitHub repo sync notes
GitLab.com [https://gitlab.com/help/workflow/repository_mirroring.md supports] pull and push sync (one of each per repository). This needs an access token for push (at least over HTTPS; push mirroring over SSH doesn't seem to be supported). GitLab Community Edition doesn't support mirroring; that's an Enterprise Edition thing. It's possible to configure CI pipelines to do it, but it's somewhat less friendly. On the other hand, the built-in mirroring isn't configurable to force-update refs, which a custom pipeline would be able to do.

[https://gitlab.com/help/ssh/README.md#deploy-keys GitLab] and [https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys GitHub] both support SSH deploy keys. These default to read-only on GitLab, and read-write on GitHub. Deploy keys are per-repository.

GitLab has [https://gitlab.com/help/api/README.md#private-tokens Private Tokens] and [https://gitlab.com/help/user/profile/personal_access_tokens.md Personal Access Tokens]. Private Tokens are for API use and supposedly allow full API access as you, but don't seem to provide push access over HTTPS. Access Tokens (with `api` scope) apparently do provide push access over HTTPS. GitHub doesn't have Private Tokens, but does have [https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/ Access Tokens].
