Thomas SharedInboxandClaude Sonnet 4.6	2336afa0d7	fix: show password required error instead of crashing when no stored password (#235 ) During _load(), check whether a password exists in secure storage and track the result in _hasStoredPassword. The password field validator now requires user input when no password is stored, so _tryConnection() fails fast at form validation instead of throwing an unhandled StateError.

Thomas SharedInboxandClaude Sonnet 4.6	c343ed6bd7	feat: monitor agent loop health every 2 hours (#217 ) - Track a heartbeat timestamp in ~/.sharedinbox-agent-heartbeat at the start of each _run_loop() invocation so we can tell when it last ran. - Add `agent_loop.py monitor` subcommand that exits 1 with a WARNING message if the heartbeat is missing, corrupted, or older than 2 hours. - Add .forgejo/workflows/monitor.yml scheduled workflow that runs the monitor check every 2 hours on the self-hosted runner; a CI failure serves as the warning when the loop is stalled. - Add 7 unit tests covering all monitor / heartbeat scenarios.

Thomas SharedInboxandClaude Sonnet 4.6	1d5eb187bf	fix: fall back to text input when mobile_scanner plugin is unavailable (#202 ) On some Android builds the mobile_scanner native plugin is not registered, causing a MissingPluginException when the send/receive screens try to open the QR scanner. Add a pre-flight _initScanner() method that starts and immediately stops a temporary MobileScannerController in a try/catch; any exception (including MissingPluginException) sets _scannerFailed=true and the UI falls back to the existing copy-paste text-input flow instead of leaving the user stuck with a blank camera view.

Thomas SharedInboxandClaude Sonnet 4.6	77e581299d	fix: filter out schedule/deploy workflow runs in CI checks _latest_main_ci_run() was using event != pull_request which still matched deploy.yml schedule runs when their prettyref == "main", blocking the loop from picking up new issues. _latest_ci_run_for_branch() had the same issue: the else branch matched any non-pull_request event including schedule runs. Both functions now explicitly filter for event == "push" only. Tests updated: rename _latest_ci_run → _latest_main_ci_run, mock _open_issue_prs to prevent real API calls in unit tests, and update _find_pr_for_branch side_effect to reflect the upstream post-merge PR-still-open verification check.

Thomas SharedInbox	3f946dfca0	fix: switch Play Store upload from httplib2 to requests The Play Store AAB upload was failing with httplib2.error.RedirectMissingLocation when Google's API returned a redirect during the resumable upload initiation. Switched from google-api-python-client (which uses httplib2 internally) to pure requests-based AuthorizedSession, which handles redirects correctly. Closes #198	2026-05-24 07:52:12 +02:00
Thomas SharedInboxandClaude Sonnet 4.6	c517f604e0	test: update deploy_playstore tests for requests-based transport The previous tests patched google_auth_httplib2 and googleapiclient which no longer exist in the new implementation. Rewrite to mock AuthorizedSession and _upload_aab_resumable, covering the same scenarios: happy path, retry on transient errors, backoff delays, and exhausted attempts.

Thomas SharedInboxandClaude Sonnet 4.6	7d393ec818	fix: switch Play Store upload from httplib2 to requests httplib2 treats 308 Resume Incomplete responses (used by Google's resumable upload API) as redirects and raises RedirectMissingLocation when the response lacks a Location header. Switch to google.auth.transport.requests.AuthorizedSession + direct HTTP calls so the upload uses the requests library, which handles 308 correctly.

Thomas SharedInboxandClaude Sonnet 4.6	7715190cbf	fix: retry AAB upload on RedirectMissingLocation with exponential backoff Adds a 3-attempt retry loop around the resumable AAB upload that catches httplib2.error.RedirectMissingLocation (a transient network error) and retries with exponential backoff (10s, 20s). A fresh MediaFileUpload is created on each attempt because resumable upload objects cannot be reused after failure. Also adds TestUploadRetry covering the retry path.

Thomas SharedInboxandClaude Sonnet 4.6	80cde04d87	fix: retry AAB upload on RedirectMissingLocation with exponential backoff (#186 ) Wrap the resumable bundle upload in a loop of up to _MAX_UPLOAD_ATTEMPTS (3) attempts. On httplib2.error.RedirectMissingLocation, recreate MediaFileUpload (resumable uploads cannot reuse the same object) and wait 10 s / 20 s before retrying. After all attempts are exhausted, raise RuntimeError chained to the last exception. Add tests covering the retry path, backoff delays, fresh MediaFileUpload on each attempt, and exhaustion.

Thomas SharedInboxandClaude Sonnet 4.6	fb6f2cca68	fix: add timeout and retries to Play Store upload (#185 ) Switch deploy_playstore.py from requests/AuthorizedSession to the googleapiclient.discovery client with google-auth-httplib2, so that AuthorizedHttp(timeout=300) enforces a hard socket timeout on all requests and num_retries=3 on every .execute() call enables automatic retries for transient failures. Update flake.nix and ci/main.go to install the new dependencies (google-api-python-client, google-auth-httplib2, httplib2) instead of the old google-auth + requests pair.
