Conversation
node/monitor is the extension that answers the operator's activity polls. It has never been installed in the session image, so MonitorActivityTracker has been polling something that cannot answer - which, combined with a poll failure being read as inactivity, is why sessions were being reaped regardless of what the user was doing. Package it on every release and attach theia-cloud-monitor-<version>.vsix, so the IDE image can install it by URL the way it already installs data-bridge. The pull_request trigger covers node/monitor, which nothing else in CI builds. vsce package refuses to run without a publisher, so build:vsix could never have worked as shipped. Set it to tum-aet, matching data-bridge, making the extension id tum-aet.theia-cloud-monitor. The version is taken from the release tag with the leading v stripped, the same normalisation the image build does and for the same reason: one release is one version string.

Merge Risk: 🟡 Moderate · up to The new workflow packages the session monitor extension and attaches it to each GitHub release. When a pre-release is published, it can run twice at the same time, and each run deletes the existing file before uploading a new one. If an upload fails, the release can be left without the extension file that installations download by URL, until someone reruns the workflow. Removing the duplicate trigger and the delete-before-upload behavior would make publishing reliable. The new workflow file also needs the required EPL-2.0 license header. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Remove the redundant prereleased trigger.
GitHub’s published event already covers pre-releases. If GitHub emits both subscribed activities for one pre-release, this workflow can build twice and start competing uploads to the same asset name. Keep published as the sole release activity. (docs.github.com)

Do not delete an existing release asset before its replacement is ready.
On a rerun, --clobber deletes the existing VSIX before uploading the new one. If that upload fails, the release loses the asset used by its installation URL. Remove --clobber and handle an existing asset without deleting it during a routine rerun. (cli.github.com)

Why
node/monitoris the VS Code extension that answers the operator's activity polls —GET /monitor/activity/lastActivity,POST /monitor/activity/popup,POST /monitor/message.It has never been installed in the session image. EduIDE's base IDE installs
builtin-extension-pack,data-bridgeandscorpio, and nothing else references@eclipse-theiacloud/monitor-theiaeither. SoMonitorActivityTrackerhas been polling an endpoint that cannot answer, on every session, forever — and because a failed poll was read as inactivity (fixed separately in #140), sessions were reaped 60 minutes after start regardless of what the student was doing.There was no way to fix that, because there was nothing to install. This produces the artifact.
What it does
monitor-vsix.ymlpackages the extension on every release and attachestheia-cloud-monitor-<version>.vsixto it, so the IDE image can pin it by URL exactly as it already pins data-bridge. Nothing is published to a marketplace — the commented-out marketplace steps in data-bridge's own release workflow suggest that was a deliberate choice there too.The
pull_requesttrigger (scoped tonode/monitor/**) exists because nothing else in CI builds this package; without it, a broken manifest would only surface at release time.Version comes from the release tag with the leading
vstripped — the same normalisationbuild.ymlrelies on, and for the same reason: one release is one version string.One thing worth knowing
vsce packagerefuses to run without apublisher:There was none, so the existing
build:vsixscript could never have worked as shipped — more fork residue. Set totum-aetto match data-bridge, making the extension idtum-aet.theia-cloud-monitor.Verified locally
Ran the exact steps the workflow runs:
→
Packaged: theia-cloud-monitor.vsix (23 files, 568 KB), and inside it:vsceinvokesvscode:prepublishitself, so the bundle is always built from the checkout rather than from whateverdist/happened to be lying around.*.vsixis now gitignored undernode/.This is not enough on its own
Two follow-ups are needed before activity tracking actually works, and they should land together:
appDefinitions.defaults.monitor.portmust stop being3000. When it equals the app port the operator drops the dedicated Service port, and the poll then goes to the Service'shttpport, which targets oauth2-proxy and can never return 200.8081(the extension's own default) is the value that works.Until both land, #140 is what protects users: a failed poll no longer times anyone out.
