as a further enhancement to efafda16f, schedule a render immediately if
500ms have passed without one, and cap the max delay to 500ms.
This removes delay for short logs, and prevents an issue where output that
is produced reasonably quickly will not be rendered for a long time.
frontend would furiously try to render as fast as it received data
chunks from the server. This causes a lot of extra load on the browser
renderer if the logs are large. Buffer and batch calls to rerender
to improve performance.

do not escape links to downstream jobs generated with a private
ANSI CSI escape sequence, because the newer ansi_up escapes HTML.
Work around its dropping of unknown sequences, and have the link
use the Vue routing mechanism rather than a page reload.
resolves#161
only a small subset of vue-router is used, and integration is
complicated by each route having its own EventSource request.
Implementing the routing directly allows simplification of
the EventSource logic.
Another motivating factor is that the vue-router packages in
debian have been unreliable, making the dependence on vue-router
a hinderance for packaging laminar in debian.
to 2.6.12 and 3.4.8 respectively, as they are the versions available
in Debian. fix an exposed issue where the status handler attempted
to manipulate the DOM before vue had rendered it - such manipulations
need to be deferred with $nextTick().
too esoteric for the front page, converting it to an example
of querying laminar db directly and using gnuplot should provide
more value to those needing deeper insights into job behaviour.
This allows build chains to be traced in the common case where
an upstream job calls `laminarc queue' instead of `laminarc start'.
Incomplete job runs now have database entries, which requires
some adjustments in queries. Queued jobs can now be viewed in
the frontend and there is a corresponding status icon.
add -h|--help usage messages to laminarc and laminard
add a mechanism to compile in a version number, and display the
version in the help messages and in the frontend.

WebUI rewritten in a more modern style, bootstrap is dropped in favour of
plain css/grid. Hand-crafted svgs replace utf-8 glyphs for a more uniform
look and smoother animation. webmanifest added for better mobile behaviour.
No doubt minor tweaks will follow...

Chrome auto-reconnects when an EventSource connection is interrupted
but Firefox doesn't. Enforce consistent behaviour by implementing
reconnect logic.
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.
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.
fix a missing js function call that broke log output in the
webui, and replace TextDecoderStream with TextDecoder because
the former isn't supported in Firefox
- regressions and recoveries: list of jobs whose run status changed,
ordered first by currently failing jobs, secondly by count of jobs
since the status change, descending for currently failing jobs and
ascending for currently passing jobs
- low pass rates: list of the jobs with the worst pass rates calculated
over all time
- run time changes: jobs with the largest changes in build time. This
is calculated as the difference between the range and the standard
deviation over the past 10 runs.
- average run time distribution: shows the number of jobs in the
system divided into buckets based on their average runtime
The computed list of filtered jobs wasn't updated when a notification
was received from the server. Switch to using a method rather than a
computed property to fix this. Also add tags to jobs reported in
job_started and job_completed notifications
This feature allows runs to be sorted by result, number, start time
or duration, in ascending or descending order, on the Job page. Request
is processed server-side so that the correct page division can be done.
Currently running jobs are not sorted.
