* MM-11420: plugins: compute bundle hash on load (#9172)Jesse Hallam2018-07-311-14/+15
| | | | | | | | | | | | * plugins: compute bundle hash on load Use this hash to bust client caches whenever the plugin bundle changes. * eliminate redundant pluginHandler * switch to 64-bit FNV-1a * Fix test
* unpack prepacked plugins on plugins initialization (#9149)Jesse Hallam2018-07-261-0/+21

* MM-8622: Improved plugin error reporting (#8737)Jesse Hallam2018-05-231-22/+218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * allow `Wait()`ing on the supervisor In the event the plugin supervisor shuts down a plugin for crashing too many times, the new `Wait()` interface allows the `ActivatePlugin` to accept a callback function to trigger when `supervisor.Wait()` returns. If the supervisor shuts down normally, this callback is invoked with a nil error, otherwise any error reported by the supervisor is passed along. * improve plugin activation/deactivation logic Avoid triggering activation of previously failed-to-start plugins just becase something in the configuration changed. Now, intelligently compare the global enable bit as well as the each individual plugin's enabled bit. * expose store to manipulate PluginStatuses * expose API to fetch plugin statuses * keep track of whether or not plugin sandboxing is supported * transition plugin statuses * restore error on plugin activation if already active * don't initialize test plugins until successfully loaded * emit websocket events when plugin statuses change * skip pruning if already initialized * MM-8622: maintain plugin statuses in memory Switch away from persisting plugin statuses to the database, and maintain in memory instead. This will be followed by a cluster interface to query the in-memory status of plugin statuses from all cluster nodes. At the same time, rename `cluster_discovery_id` on the `PluginStatus` model object to `cluster_id`. * MM-8622: aggregate plugin statuses across cluster * fetch cluster plugin statuses when emitting websocket notification * address unit test fixes after rebasing * relax (poor) racey unit test re: supervisor.Wait() * make store-mocks

* MM-8622: improved plugin error handling (#8692)Jesse Hallam2018-05-011-37/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * don't report an error on plugin activation if already active * improved plugin logging events Log an error when a plugin's ServeHTTP fails, or when it unexpectedly terminates. Restart a plugin at most three times, allowing its failure to later bubble up under the "failed to stay running" status. * clarified plugin activation/deactivation Avoid repeatedly activating when any configuration bit changes. Improved logging. * constrain plugin ids to ^[a-zA-Z0-9-_\.]+$ and enforce minimum length Previously, the plugin id was used unsanitized to relocate the plugin bundle, which allowed writing outside the `plugins/` directory by using an `id` containing `../`. Similarly, an empty string was accepted as an id and led to unexpected error messages. * remove plugins by manifest path, not id If the id within the manifest ever diverges from the actual plugin location, it becomes impossible to remove via the API. Instead, if the plugin is found by id, remove the path containing the manifest. * ignore plugins with nil manifests If a plugin was detected, but had a manifest that couldn't be parsed, it will be left nil but still be listed among the packages. Skip over these in most cases to avoid segfaults. * leverage mlog more effectively for plugins * build issues
