David Smiley resolved SOLR-9085. -------------------------------- Resolution: Fixed > DateRangeField is broken before the year 1582 > --------------------------------------------- > > Key: SOLR-9085 > URL: https://issues.apache.org/jira/browse/SOLR-9085 > Project: Solr > Issue Type: Bug > Affects Versions: 6.0 > Reporter: David Smiley > Assignee: David Smiley > Fix For: 6.1 > > Attachments: SOLR-9085.patch > > > DateRangeField has some issues for dates before 1582 (the Gregorian Change > Date), following Solr 6. The main problem is that it uses DateMathParser > which no longer observes a GCD and then it converts that Date to a Calendar > using Calendar.setTime(date) which considers the GCD. We can't altogether > avoid Calendar.java as in SOLR-9080 because DateRangePrefixTree currently > fundamentally depends on it. However I recently learned we can simply change > the GCD like so: {{cal.setGregorianChange(new Date(Long.MIN_VALUE));}} > beforehand. DateRangeField also calls Calendar.getTime as well, which is > affected by GCD considerations. > For users that use DateRangeField but do *not* use "Date Math" and do not > have 'Z' in their date strings then date strings are completely parsed by > DateRangePrefixTree and there should be no issue. > DateRangePrefixTree ought to be improved a bit too (in a separate issue)... > like making the GCD configurable, and setting using > SimpleDateFormatter.setCalendar it uses to format. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
