2510	[r=rogpeppe] agent: safer and more flexible [r=rogpeppe] agent: safer and more flexible For the machine agent, we need a way of safely updating the agent configuration from multiple places. The singleton approach wasn't cutting it, and isn't very Go like (communicating by sharing memory n' all). So we change agent.Config to split out setting and writing methods, so that the majority of places that use it can use read-only methods. We add a Clone method to make it possible to pass around a read-only copy of a mutable config. We also factor out some methods that are really behavioural and not directly to do with Config (except that they use information from the Config). This means that any config changes they make can be made under control of external code. https://codereview.appspot.com/81570043/	Roger Peppe	10 years ago
2443	[r=dimitern],[bug=1291400] upgrades: Local provider 1.16 to ... [r=dimitern],[bug=1291400] upgrades: Local provider 1.16 to 1.18 migration This adds a couple of utility methods: - agent.MigrateConfig() - allows to atomically change and save an existing agent config (only DataDir, LogDir, Jobs or Values); - agent.PatchConfig (only for tests) - to facilitate testing of the above. Then, we add an upgrade step for migrating existing 1.16 local environments to 1.18, including: - agent config (DataDir, LogDir, Jobs, Values) - rsyslog configuration and setup - environment config (container and namespace settings) - removing deprecated stuff (shared-storage dir and the related settings in the agent config). In addition, a few changes and drive-by fixes were done to related packages. Tested extensively live using a 1.16 local environment upgrading to 1.18. https://codereview.appspot.com/77340044/ R=fwereade	Dimiter Naydenov	10 years ago

2361	[r=wallyworld] Machine agent runs upgrade operations [r=wallyworld] Machine agent runs upgrade operations When the machine agent starts, it runs whatever upgrade operations are relevant according to the agents's jobs. The upgrades need to complete before any of the workers are started. Changes to machine agent tests were needed because now a machine needs to be properly provisioned for the agent to start up, since the access to the state api will fail unless a machine is provisioned. Also included are some drive by fixes to some syslog and version tests from other reviews. https://codereview.appspot.com/68250046/	Ian Booth	10 years ago
2332	[r=wallyworld] Version and upgrade refactorings [r=wallyworld] Version and upgrade refactorings A few small changes from a previous review. 1. Replace Version.Less() with Version.Compare() 2. Rename UpgradeStep, UpgradeOperation, UpgradeTarget to Step, Operation, Target. https://codereview.appspot.com/64880043/	Ian Booth	10 years ago
2324	[r=wallyworld] Upgrade rsyslog config files [r=wallyworld] Upgrade rsyslog config files Add upgrade capability for rsyslog config files. A chunk of code refactoring was also done. Previously committed code to upgrade the uniter lock directory was moved to its own file, plus code to test rsyslog config contents was pulled out so it could be reused. https://codereview.appspot.com/62950043/	Ian Booth	10 years ago

This branch also adds an upgrade step to make sure that existing environments also get the goodness. https://codereview.appspot.com/62390043/	Tim Penhey	10 years ago
2317	[r=wallyworld] Fixes to upgrade infrastructure [r=wallyworld] Fixes to upgrade infrastructure The initial upgrade framework was including steps for the current version by mistake. Additional tests also added. https://codereview.appspot.com/61510049/	Ian Booth	10 years ago
