Implement a separate process, the "leader", which runs all the
scripts for a job run, instead of directly from the main laminard
process. This makes for a cleaner process tree view, where the
owning job for a given script is clear; also the leader process
acts as a subreaper to clean up any wayward descendent processes.
Resolves#78.
The nodes/tags system has not been particularly successful, it's not as
intuitive as it could be, and in an attempt to be a single feature to address
many use cases, ends up addressing none of them particularly well.
This commit replaces nodes and tags with contexts.
Each job may define which context(s) the job may be associated with.
Laminar will only pop the job off the waiting queue when it can be assigned
to a context. A context defines an integer number of executors, which
represents how many runs can be simultaneously assigned to it. A context
may provide extra environment variables.
Essentially, a context replaces a node, and tags are gone. You just assign
jobs to contexts directly, and you can use a glob expression. This should be
more intuitive.
For grouping jobs in the WebUI, a separate mechanism called "groups" is provided.
Large refactor that more closely aligns the codebase to the kj async
style, more clearly exposes an interface for functional testing and
removes cruft. There is a slight increase in coupling between the
Laminar and Http/Rpc classes, but this was always an issue, just until
now more obscured by the arbitrary pure virtual LaminarInterface class
(which has been removed in this change) and the previous lumping
together of all the async stuff in the Server class (which is now
more spread around the code according to function).
This change replaces the use of Websockets with Server Side Events
(SSE). They are simpler and more suitable for the publish-style messages
used by Laminar, and typically require less configuration of the
reverse proxy HTTP server.
Use of gmock is also removed, which eases testing in certain envs.
Resolves#90.
Create example Dockerfile and document its use in the User Manual.
This provides a minimal Alpine Linux based starting point for users who want to build a custom Laminar Docker container.
Fix all hrefs and vue routes to correctly operate against the
<base href> tag. Add a configuration parameter to override the
content of the href attribute, and describe its use.
