> camel-google-calendar: stream consumer can skip events and only reads the
> first page
> ------------------------------------------------------------------------------------

> Key: CAMEL-24343
> URL: https://issues.apache.org/jira/browse/CAMEL-24343
> Project: Camel
> Issue Type: Bug
> Components: camel-google-calendar
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Major
>
> {{GoogleCalendarStreamConsumer}} can silently skip events when
> {{considerLastUpdate=true}}:
> {code:java}
> // GoogleCalendarStreamConsumer.java:154-167
> if (!dateList.isEmpty()) {
> ...
> calendar.add(java.util.Calendar.SECOND, 1);
> finalLastUpdate = calendar.getTime();
> } else {
> finalLastUpdate = new Date();
> }
> {code}
> * On a poll that returns no events the cursor is advanced to the local {{new
> Date()}}, so any event updated between the previous poll and "now" (including
> clock-skew between the local machine and Google) is never delivered.
> * On a non-empty poll the cursor is set to the newest event's update time
> plus one second, so events updated in that same second are skipped.
> In addition, the non-sync branch never follows the page token:
> {code:java}
> // GoogleCalendarStreamConsumer.java:134
> c = request.setOrderBy("updated").execute();
> {code}
> Only the first page (maxResults, default 10) is ever consumed, and because
> the cursor still advances the remainder is dropped.
> Two smaller issues in the same class:
> * The 410 (invalid sync token) handler recurses into itself, {{return
> poll();}} at :117, with no bound.
> * {{c.getItems()}} is dereferenced without a null check at :123 and :138.
> Found during a source audit of the {{components/camel-google}} module family
> against main @ c3b01310be15.
