Night shift notifications on weekends were missing the type label,
making them ambiguous. Also fix schedule post text fallback to use
this_monday instead of now for the start date.
Dependabot now scans per-function requirement directories instead
of the repo root. Admin override/open/clear commands accept an
optional day/night parameter for weekend day shift management.
- Add _find_employee_shift() to check both day/night on weekends
- Drop/swap now correctly find and operate on weekend day shifts
- Pick finds first available shift type on weekends
- Admin override/open/clear update 3CX for same-day active shifts
- Ring scheduler: use DynamoDBCrudPolicy (resolve_shift needs Query)
- Button pickup: update 3CX for active shift type, not just night
- Pick/drop/swap commands: only update 3CX when shift type is active
- Swap command: add missing past-date guard
- add_roster_entry: reject if extension already exists
- Apply ruff formatting
The 3CX routing was changed from ring group 800 to queue 801 in a
previous PR on ring-scheduler-3cx. Updates all callers and the SAM
template parameter default accordingly.
- Reject /oncall pick and /oncall drop for past dates
- Show ephemeral error when stale pickup buttons are clicked
- Hide pickup buttons for dates in the past
- Add explicit "Day (8am-5pm)" and "Night (5pm-8am)" labels to
schedule lines, pickup buttons, and shift change notifications
- Store schedule message timestamp in DynamoDB (SCHEDULE_POST record)
- Delete previous week's schedule post before posting the new one
- Live-update the schedule post via chat_update after any
pick/drop/swap/button-pickup so it always reflects current state
- Add afterhours-ring-scheduler Lambda with 4 EventBridge rules
(daily 8am EST/EDT + weekend 5pm EST/EDT) for 3CX ring group
routing updates
- Extract shared ring_scheduler.py module for direct ring group
updates from both the scheduled Lambda and the Slack bot
- Replace cross-Lambda invoke with direct update_ring_group() call
in the Slack bot — eliminates lambda:InvokeFunction dependency
- Use RingGroup API (correct) instead of Queue API (was wrong in
the original ring-scheduler repo)
- Eliminate YAML config fallback — DynamoDB is the sole schedule
source
- Add RingGroupNumber CloudFormation parameter
- Slack bot token and signing secret now read from Secrets Manager
- 3CX credentials (domain, client-id, client-secret) moved to
Secrets Manager under afterhours-shift-manager/3cx-* prefix
- Channel ID is now a non-secret CloudFormation parameter (ShiftChannel)
- Add shared secrets.py helper for Secrets Manager reads
- Remove SSM and KMS IAM policies, add secretsmanager:GetSecretValue
Move from flat src/ to per-function directories:
- src/slack-bot/ — Slack Bolt Lambda handler
- src/weekly-post/ — Monday schedule + pay post
- src/roster-sync/ — Daily 3CX roster sync
- src/shared/ — Lambda Layer with schedule, blocks, three_cx_client
Each function has its own requirements.txt and CodeUri. Shared
modules are deployed as a SAM Layer (afterhours-shared) importable
as `from shared.X import Y`.
- Set arm64 architecture globally for all Lambda functions
- Add explicit CloudWatch log groups with 60-day retention
- Add missing WeeklyPostFunctionArn to stack outputs
- Add Dependabot assignees for both ecosystems
- Add samconfig.toml.example for onboarding
The date comparison used git's author date in its stored timezone
(e.g. -04:00) against GitHub API mergedAt values in UTC (Z suffix).
Lexicographic string comparison across different timezone formats
caused every PR from the tagged commit's day to be re-included in
subsequent versions. Normalize to UTC with format-local so both
sides match.
Also replace the hardcoded canvas URL with the CANVAS_ID env var
already available in the step.
Two root causes:
- claim_open_shift ConditionExpression failed when no OVERRIDE record
existed (shift available via weekly fallback). Added attribute_not_exists
check so claims succeed for both missing and OPEN overrides.
- Slack ack timeout: chat_postMessage took too long before respond() was
called, causing Slack to show an error. Moved respond() first and made
channel notifications best-effort with try/except.
