Why: Improve reliability of the imjournal basic test under CI timing variance and journal churn, reducing non-actionable failures. Impact: imjournal basic tests become more resilient and may skip when host journal load is excessive. Before/After: test could fail due to startup/noise races; now it waits for readiness, retries under noise, and reports cleaner errors. Technical Overview: - Added a readiness probe phase in imjournal-basic before the real assertion message to avoid IgnorePreviousMessages startup races. - Added short retry logic for high recent journal volume and skip only after retries are exhausted. - Added tunables for noise window, threshold, retries, and sleep. - Updated journal_print to write newline-terminated records and explicitly fflush/fclose so writes are durably handed to journald. - Updated content_check_with_count to treat missing output file as not-yet-done until the test hard deadline, then fail. - Improved failure diagnostics for missing output file to avoid secondary shell errors that obscure the primary failure.

/* A testing tool that tries to emit message given as argument
|
|
* to the journal, and, if succceds (at least per journald retcode).
|
|
* If whole operation is successful there is need to actually check
|
|
* that message is present in journal (also veryfing journal read perms)
|
|
*
|
|
* Retcodes: 0 - success
|
|
* 1 - wrong arguments (expects exactly one)
|
|
* 2 - failed to open journal for writing
|
|
* 3 - failed to actually write message to journal
