In the client view list, only show running allocations count for each
client, rather than include already completed tasks.
This is done for two reasons:
First, consitency with the CLI: `nomad node status --allocs` only
shows running allocs.
Second, and more importantly, the count is useful to estimate how loaded
the clients are. Allocs that have completed (but not GCed yet) have
very little value to operators.
This would happen because a no connection error happens after the second request fails, but
that's because it's assumed the second request is to a server node. However, if a user clicks
stderr fast enough, the first and second requests are both to the client node. This changes
the logic to check if the request is to the server before deeming log streaming a total failure.
Typically a failover means that the client can't be reached. However, if
the client does eventually return after the timeout period, the log will
stream indefinitely. This fixes that using an API that wasn't broadly
available at the time this was first written.
This closes#7456. It hides the terminal when the job is dead and
displays an error when trying to open an exec session for a task
that isn’t running. There’s a skipped test for the latter behaviour
that I’ll have to come back for.
This closes#7454. It makes use of the existing watchable tools to
allow the exec popup sidebar to be live-updating. It also adds
alphabetic sorting of task groups and tasks.
This is a minimal implementation that closes#7463. It doesn’t include
true support for moving around within the command to edit using arrow
keys because it gets too complex when managing wrapping at the edge of
the terminal. Instead, arrow keys are ignored. It also ignores ^A and
^E, which are cursor manipulations that pose similar problems to arrow
keys. It does support ^U, which deletes the entire command.
It also allows a command to be pasted, which was previously unsupported.
This is accomplished by migrating from Xterm.js’s onKey handler to
onData, which is recommended here:
https://github.com/xtermjs/xterm.js/issues/2673#issuecomment-574897733
onData is a higher-level handler that issues events with the final
interpreted data instead of the individual key events. That means the
processing in this PR has changed from inspecting DOM key events to
inspecting their ASCII equivalents, which I’ve extracted into a utility
dictionary for use in tests and implementation.
One consequence of ignoring most control characters is that if you paste
a string that includes a control character, that character will be
stripped. It’s somewhat strange for compound sequences like arrow keys;
if you run copy('/bin/b' + '\x1b[D' + 'ash') in a Javascript console and
paste what’s on the clipboard, you get "/bin/b[Dash". That’s because
the left arrow key, as in that centre portion of the string,
is represented by the escape character and a coded sequence. Stripping
the control character leaves the coded sequence as part of the paste.
That seems like an acceptable compromise vs either ignoring any pasted
string with control characters (confusing UX) or trying to interpret and
strip all such compound control sequences (difficult to be exhaustive).
This effectively overrides Bulma's default field layout tweaks
at different breakpoints. This includes going from flex to block
and different font-sizes.
The "default" order values as set by Bulma are different for different
breakpoints. Since this wasn't considering breakpoints, it resulted
in the unexpected reordering of pagination elements as different page
widths. Turns out removing this property gives us what we want.
When a node has no host volumes, the API response will
have a null value for the HostVolumes attribute, which
in turn becomes a null value instead of an empty array
in the store. This protects against that, ensuring host
volumes is always an array.
This closes#7476. The decomposition of computed properties
is necessary to avoid nested aggregate dependent keys; the
previous dependent key of `taskGroup` will be inadequate
when the sidebar becomes live-updating.
Closes#7197#7199
Note: Test coverage is limited to adapter and serializer unit tests. All
acceptance tests have been stubbed and all features have been manually
tested end-to-end.
This represents Phase 1 of #6993 which is the core workflow of CSI in
the UI. It includes a couple new pages for viewing all external volumes
as well as the allocations associated with each. It also updates
existing volume related views on job and allocation pages to handle both
Host Volumes and CSI Volumes.
This connects Xterm.js to a Nomad exec websocket so people
can interact on clients via live sessions. There are buttons on
job, allocation, task group, and task detail pages that open a
popup that lets them edit their shell command and start a
session.
More is to come, as recorded in issues.
I originally planned to add component documentation, but as this dragged on and I found that JSDoc-to-Markdown sometimes needed hand-tuning, I decided to skip it and focus on replicating what was already present in Freestyle. Adding documentation is a finite task that can be revisited in the future.
My goal was to migrate everything from Freestyle with as few changes as possible. Some adaptations that I found necessary:
• the DelayedArray and DelayedTruth utilities that delay component rendering until slightly after initial render because without them:
◦ charts were rendering with zero width
◦ the JSON viewer was rendering with empty content
• Storybook in Ember renders components in a routerless/controllerless context by default, so some component stories needed changes:
◦ table pagination/sorting stories access to query params, which necessitates some reaching into Ember internals to start routing and dynamically generate a Storybook route/controller to render components into
◦ some stories have a faux controller as part of their Storybook context that hosts setInterval-linked dynamic computed properties
• some jiggery-pokery with anchor tags
◦ inert href='#' had to become href='javascript:;
◦ links that are actually meant to navigate need target='_parent' so they don’t navigate inside the Storybook iframe
Maybe some of these could be addressed by fixes in ember-cli-storybook but I’m wary of digging around in there any more than I already have, as I’ve lost a lot of time to Storybook confusion and frustrations already 😞
The STORYBOOK=true environment variable tweaks some environment settings to get things working as expected in the Storybook context.
I chose to:
• use angle bracket invocation within stories rather than have to migrate them soon after having moved to Storybook
• keep Freestyle around for now for its palette and typeface components
This builds on API changes in #6017 and #6021 to conditionally turn off the
“Run Job” button based on the current token’s capabilities, or the capabilities
of the anonymous policy if no token is present.
If you try to visit the job-run route directly, it redirects to the job list.
There are two changes here, and some caveats/commentary:
1. The “State“ table column was actually sorting only by status. The state was not an actual property, just something calculated in each client row, as a product of status, isEligible, and isDraining. This PR adds isDraining as a component of compositeState so it can be used for sorting.
2. The Sortable mixin declares dependent keys that cause the sort to be live-updating, but only if the members of the array change, such as if a new client is added, but not if any of the sortable properties change. This PR adds a SortableFactory function that generates a mixin whose listSorted computed property includes dependent keys for the sortable properties, so the table will live-update if any of the sortable properties change, not just the array members. There’s a warning if you use SortableFactory without dependent keys and via the original Sortable interface, so we can eventually migrate away from it.
As the angle bracket invocation RFC says:
> There is no dedicated syntax for passing an "else" block
> directly. If needed, that can be passed using the named
> blocks syntax.
https://github.com/emberjs/rfcs/blob/master/text/0311-angle-bracket-invocation.md#block
Unfortunately, using a contextual component doesn’t help as
the yield inside that component will still result in content
rendering that would show when the source isn’t empty. So
we decided to change the interface so you have to check
whether the source is empty before using it, which aligns with
how list-table works.
This is mostly deprecation fixes and blueprint changes. There
are some dependency updates too; the changes to Ember
Basic Dropdown necessitated changing it to angle bracket
component invocation. The conversion of the rest of the
templates will happen separately.
This fixes a race condition in the pseudo-relationship between a
TaskState and a Task that was causing the Consul Connect proxy tag
to sometimes show on the wrong task. There’s no direct Ember Data-style
relationship between a TaskState and its Task; instead, it’s determined
by searching for a Task with the matching name. The related Task was
sometimes stored before everything was ready and not recalculated when
the name became known. This ensures the relationship is accurate if the
TaskState’s name property changes.
Protect against case where an alloc has no services and avoid
dereferencing null.
Here, we ensure that the model and test serializers mimic the API by
having nil TaskGroup.Services instead of an empty array.
I put this property in the wrong place.
I’ve found how to fix the mock API in the tests but
they’re failing to pass with headless Chrome only,
so they’re skipped for now.
This was causing elements to flow off the page, since the element was
assuming 100% but also had a 250px margin for the left column.
This had previously been "fixed" by setting overflow-x: auto, but that
resulted in tooltips from being clipped.
This is a better solution to the same problem.
It may be an Ember bug: in some circumstances, the
ember-transitioning-in class was persisting in table
sort links even after the transition completed. This
changes the transition animations to be targeted only
for breadcrumbs and directory links.
The new streaming-file component takes an arbitrary logger component
along with some mode flags and handles things like polling, DOM updates,
and scroll position.
When sorting by size, directories are sorted by name, as size
isn’t displayed.
This includes a change to the positioning of sort arrows for all tables,
moving them closer to the text, because in some cases, the arrows
for right-aligned columns were ambiguously positioned.
This uses ember-page-title to add dynamic page titles throughout the
route hierarchy. When there’s more than one region, the current
current region is added before the final entry of “- Nomad”.
