[1.7.1] - 2023-02-20

• daemon: improve shutdown when jobs fail
• daemon: log decoding errors

[1.7] - 2023-01-08

• Fix InvalidPath for case insensitive conflicts on macOS

• Handle common store path errors to print a human readable exception

• Pretty Print C+ exceptions

• Deploy: don't throw errors when bootstrapping fails

[1.6.1] - 2023-09-25

Fixed

• deploy: Correctly format cachix deploy agent exception messages

• deploy: use high-level activate script for Darwin

• deploy: Support darwin-version.json

• #547: Filter invalid paths when watching the store

• Filter out existing upstream paths when using watch-exec

• Retrying is now printed as stderr, which is important for watch-exec automation

[1.6] - 2023-06-27

Added

• cachix remove MYCACHE: reverses cachix use MYCACHE.

Changed

• cachix push now displays a progress bar and summary before pushing.

[1.5] - 2023-05-17

Added

• cachix pin - See https://docs.cachix.org/pins

Fixed

• Reverted "Rewrite C++ bits to Haskell"

  This reverts 15 commits related towards getting Cachix to built statically without C++ code in Nix.

  Since it's not possible to interact with Nix sqlite directly in a reliable manner, we'll go the route of autogenerating C++ binding without Template Haskell, at some point.

[1.4.2] - 2023-04-05

Fixed

• Fix watch-* command with the new Store implementation by openining a new connection each time.

[1.4.1] - 2023-03-31

Fixed

• Open Nix database in read-only mode instead of immutable.

[1.4] - 2023-03-26

Changed

• Rewrote C++ bindings to Nix in Haskell, reducing the closure and making it easy to statically compile Cachix.

[1.3.3] - 2023-03-18

Fixed

• Fix watch-exec exiting too soon.

[1.3.2] - 2023-03-17

Fixed

• Fix build on GHC 9.4

[1.3.1] - 2023-03-09

Fixed

• Signal handling in watch-exec & watch-store commands.

[1.3] - 2023-03-06

Added

• Upload nars using multiple parts, improving bandwidth speed and parallelization.

Changed

• Bump defaults jobs to 8.
• Improve 401 erros by showing the body of backend response.
• Deploy: improve agent startup and shutdown.

Fixed

• Unblock interrupt signal on darwin (possibly also Linux).
• Deploy: wait for the logs to finish when activating.

[1.2] - 2023-01-06

Added

• NARs are now streamed without invoking an external process, so if you have a lot of small files, there should be some significant performance improvements

• cachix deploy activate now by default waits for the agents to be deployed, displays the logs and exists if any deployments fail. If you'd like to keep the old behaviour pass --async flag.

Changed

• We no longer pin Nix to speed up version bumps of Nix

Fixed

• A number of improvements to stability of the websocket connection used in cachix deploy.

• Fixed a regression in cachix deploy activate, requiring --agent flag that should be optional.

• Fixed a C++ crash that would sometimes happen on exceptions in rare conditions.

[1.1] - 2022-12-16

Added

• Use ZSTD compresion method by default and allow overriding it via --compression-method back to XZ. You can also change the default permanently on your binary cache settings page.

• Cachix Deploy got a complete rewrite with correctness in mind and reliablity.

• Cachix Deploy agent now supports --bootstrap that awaits a new agent to spawn and then shuts down.

• Cachix Deploy now supports home-manager

• Generated NixOS module now uses the naming of Nix settings as introduced in NixOS 22.05.

[1.0.0] - 2022-09-06

• Cachix Deploy: disable negative narinfo caching

[0.8.1] - 2022-07-26

Fixed

[0.8.0] - 2022-07-10

[0.5.1] - 2020-11-09

Fixed

• Regression: use auth token when using signing key with private caches
• Configure netrc even if cachix config doesn't exist

[0.5.0] - 2020-11-06

  • Don't suggest creating a cache when generating keypair as it's the wrong order

  • #290: Explain what is going on when there's no signing key

  • #262: improve instructions when on NixOS and the user is untrusted

0.3.7 - 2020-03-12

Added

• Get deriver and references from C++ structures rather then shelling out (slight performance improvement)

• #251: Assert nar hash before creating narinfo

  Fixes rare but annoying bug of "bad nar archive" from Nix. Never managed to reproduce. One theory is that the path disappears as its deleted by GC or nix-store --delete.

• Print correct path when passing --nixos-folder and encountering an error

0.3.6 - 2020-02-22

Fixed

• #275: support LTS-13.x and GHC 8.2.2

Added

Fixed

• #258: don't swallow exceptions while --watch-store
• NixOS: instruct to use sudo

0.3.4 - 2019-10-01

Fixed

• #240: push: prefer store paths as command arguments over stdin

  Some programming languages like go and nodejs always open stdin pipe, which confuses cachix to think there's stdin content.

  Sadly checking stdin for contents is tricky since we get into the whole buffering mess.
