Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

1.0.1 - 2023-10-10

Added

Fixed

Changed

  • Updated Debian to bookworm
  • Updated zeitgitterd to 1.1.6
  • Updated git timestamp to 1.1.1 (through zeitgitterd)

1.0.0 - 2021-11-04

Added

  • Notice in run.sh that some gpg (not gpg1) commands seem to remove the keys of the PGP Digital Timestamping Service (probably due to their old format). If that happens, running docker-compose exec --user 15177 autoblockchainify gpg1 --pgp2 --import /stamper.asc will load the keys again.

Fixed

Changed

  • Upgraded to debian:bullseye-slim

0.9.6 - 2021-06-25

Added

  • Name and print threads for debugging
  • Allow additional daemon paramaters (e.g., --debug-level XDEBUG) to be passed to make test
  • Additional debug level XDEBUG ("excessive debug"). If you want your configuration to be backward-compatible, do not use --debug-level XDEBUG, which will raise an exception at start of older versions, but --debug-level 3.
  • Documentation for real-world mail test (and test for it)

Fixed

  • Spurious error message "Logfile vanished. Double mail receive thread?" was caused by too little wiggle room for timestamping+delays and bad logic (logfile creation wasn't the precondition for waiting for the mail). This resulted in every second mail-based timestamp being skipped for the example setup.
  • Made mail logic more robust (see comment before async_email_timestamp())

Changed

  • Commit messages now use "🔗" emoji directly instead of ":link:"
  • Streamlined and improved logging messages; switched to Signale, using aligned mode (more readable without ANSI colors)
  • Rely on deltat library instead of local copy
  • No extra delay after last timestamper

0.9.5 - 2021-01-16

Added

  • Allow docker image to be built with a specific PyPI version (a feature you probably will not need, but is useful while developing/testing)
  • Direct ability to run development docker

Fixed

Changed

  • Version numbers of non-tagged versions now end in .postX, where X is the number of commits since the tag (unless overridden by FORCE_VERSION environment variable)
  • Require git timestamp version of at least 1.0.4
  • Docker image slightly smaller
  • Docker processes run as user blockchain for more defensive security
  • During a transition phase, there will be an ownership change for the /blockchain directory subtree (will be triggered if that directory is not writable by the user blockchain)

0.9.4 - 2020-12-09

Added

  • Documentation in the config files for --zeitgitter-sleep

Fixed

  • Copy-paste like rebase problems with --zeitgitter-sleep, --push-repository, and --domain leading to termination; releasing hotfix

Changed

0.9.3 - 2020-12-09

Added

  • --zeigitter-sleep allows to sleep between upstream timestamps, e.g. to ensure a consistent ordering of cross-timestamping events for each commit.
  • Time intervals (such as "5m3.5s") may skip the seconds indication, s. So --zeigitter-sleep=0 is also valid.
  • On restart, tries to resume waiting for a mail response from PGP Digital Timestamping Service (was added some versions ago, but never documented)
  • Timespans may also indicate the number of weeks now (e.g., "1w 2d 8h 40m 3.5s")
  • Simplfied using multiple cross-timestampers:
    • Add support to push all branches using --push_branch=*, saving the need to list/update them all (see also Changes below)
    • --zeigitter-timestamp no longer needs a branch name, if git timestamp will determine it correctly. This leads to much shorter and more maintainable lists of cross-timestamping servers.

Fixed

  • Docker health check failed due to missing wget

Changed

  • The interval defaults (10m with changes, at least once every 1h) in the configuration have been adopted to what is documented.
  • Docker image is now based on debian:buster-slim. As the same number of packages (171) has to be added on top of it, starting with the smaller image is preferable. (See [#0.9.6---2020-08-13](v0.9.6 below) for why not using one of the python base images.)
  • Default for --push-branch is now *, meaning --all (which cannot be expressed in the config file)

0.9.2 - 2020-10-02

Added

  • Suspend "normal" (non-forced) commits during merge, in order to not interfere with manual maintenance processes
  • Prevent git timestamp > 1.0.3 from creating ~/.gitconfig; instead, it will record key IDs in ~/.git/config, keeping the blockchain cleaner

Fixed

  • Handle that .gnupg also is in the volume now
  • Send out mail only every force interval. Also, do not trigger immediate addition of a mail reply only, avoiding double commits/timestamps every force interval on idle repositories.

Changed

0.9.1 - 2020-09-27

Added

  • Support .ssh directory in the blockchain directory (not included in the Blockchain by default)

Fixed

  • sample.env now contains the actual names of the environment variables.
  • Serialization for mail-related processing to avoid duplicate work and race conditions

Changed

  • Format of PGP Timestamper request mail message (ISO 8601 format)

0.9.0 - 2020-09-26

Added

  • Derived from Zeitgitter timestamping server

Fixed

Changed
