Subject [jira] [Commented] (LUCENE-4613) CompressingStoredFieldsWriter ignores the segment suffix if writing aborted
Date Tue, 11 Dec 2012 15:47:22 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4613?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13529065#comment-13529065

Yes I think it'd be even better. You can use _TestUtil#randomSimpleString(Random, int maxLength).

In fact, using random segment suffix is very difficult to achieve, as we cannot ensure that
the codec instantiated through SPI will get the same segment suffix as the codec instantiated
in the {{TestCompressingStoredFieldsFormat#setUp()}, and therefore the {{_TestUtil#checkIndex(Directory
dir)}} will fail. The segment suffix must be deterministic, e.g., similar to the current solution
using the formatName as segment suffix.

> If the writing is aborted, CompressingStoredFieldsWriter does not remove partially-written
files as the segment suffix is not taken into consideration.
