v0.5.3

A full set of changes can be found here.

Highlights:

• Updated compatibility to docker 0.11.1.
• Fixed a mounting error with relative folders.
• Added more debugging information when the DEBUG=1 environment variable is set.

Upgrading:

• Hroot is now designed to interoperate with docker 0.11.1, and unofficially 0.10.x.
• This is likely a backwards-incompatible change, as docker's API has changed again.
• If you're not ready to upgrade, stick with the previous release of Hroot, which uses docker 0.7.2.

Other comments:

The DEBUG=1 environment variable now prints a lot more information, with the intention of troubleshooting remote user's problems or issues with docker interactions. This can be rather verbose.

For now, the old debug behaviour (simply printing a stack trace on crash) has been changed to a DEBUG_STACK=1 environment variable. In the future, we'd like to improve this with proper log-levels.

v0.5.2

A full set of changes can be found here.

Highlights:

• Added -H flag passthrough to connect to any docker daemon.
• Hroot now cancels a build with a helpful message if your git config isn't ready to commit yet.
• Fixed a bug where Hroot could crash if the Docker cache was cold.

Upgrading:

• Hroot will no longer start its own Docker daemon; this behaviour was confusing and would generally trigger when something else wasn't working.

v0.5.1

A full set of changes can be found here.

Highlights:

• Fixed a bug where the graph could fail to detect you have an image.
• Added --epoch flag to hroot build to disable the recording of modified timestamps.
  • See #38 for more details.

v0.5.0

A full set of changes can be found here.

Highlights:

• Renamed project to Hroot. Hroot gives you Historical Roots!

Upgrading:

• Configuration files are now called hroot.toml.
• Branch names are now prefixed with hroot/ instead of docket/.

v0.4.0

A full set of changes can be found here.

Highlights:

• New documentation with a tutorial to help new users get started.
• The configuration file syntax has been split into sections! Much easier to understand.
• Massive improvements to the way Docket interacts with your graph.
  • Operations involving git should now be faster, smoother, and less surprising.
• Docket now attempts to use the system default daemon (in /var/run) by default.
• Cache detection was improved - no more loading from the graph unnecessarily.
• Updated to Golang 1.2.

Upgrading:

• The graph now uses the consistent branch prefix docket/image/.
  • You will need to rename your branches accordingly.
• Additionally, Docket v0.4.0 lays down the contract of each commit beginning with the image name.
  • This will allow us to support loading a specific branch's commit in the future (see #7).
  • Nothing is required right now, but for future compatibility it's advised you amend your commits.
• Configuration files are now called docket.toml and have a new layout.
  • See #20 and #34 for reasoning and major changes. We think you'll like it!
• Docket no longer assumes a default command; failing to provide one will now exit with an error.
• The build flag --noop is now less confusing and is no longer used for bootstrapping.
• Docket will now unconditionally use the system default daemon if it is running, then falls back on old behavior (looking for a dock folder and/or starting a daemon itself). In the future a -H flag will be added to make this easier (see #28).

Other comments:

Building Docket now requires Golang 1.2 due to switching out our use of a forked tar library.

This change mirrors a decision already made upstream by Docker.

With several Docket subsystems now firming up rather nicely, we've added several unit tests.

These can be run with ./goad test.

v0.3.0

A full set of changes can be found here.

Highlights:

• Docket graphs now hold the container's files, not tar archives. See a diff of your entire system!
• Docket now checks if the docker cache has the image you're requesting. You can now be reasonably sure you will never pull from the docker index unless explicitly requested via -s index.
• Lots of bug fixes and code cleanup under the hood.

Upgrading:

• Because the graph format no longer uses tars, loading from & saving to an old graph will not work! We have not implemented a system to carry your graph forward; you will need to rebuild.
• Docket no longer assumes a default image name; failing to provide one will now exit with an error, rather than launching Ubuntu.

Other comments:

Please note that there's an inherent race condition in checking if the docker cache has an image; another docker client could delete the image between check & use, which would trigger an index pull from docker. We have little control over this :(

This will be documented and possibly prevented further. For now, users in sensitive environments should still consider the standard /etc/hosts rule to block index.docker.io.

v0.2.0

A full set of changes can be found here.

Highlights:

• Significant refactoring of docket commands!
• Added version command.

Upgrading:

• All docket commands have been simplified into docket run and docket build. More details are available in the readme.

v0.1.0

Initial release!
