Earwin Burrfoot commented on LUCENE-2818:
-----------------------------------------
bq. Can abort() have a default impl in IndexOutput, such as close() followed by
deleteFile() maybe? If so, then it won't break anything.
It can't. To call deleteFile you need both a reference to papa-Directory and a
name of the file this IO writes to. Abstract IO class has neither. If we add
them, they have to be passed to a new constructor, and that's an API break ;)
bq. Would abort() on Directory fit better? E.g., it can abort all currently
open and modified files, instead of the caller calling abort() on each
IndexOutput? Are you thinking of a case where a write failed, and the caller
would call abort() immediately, instead of some higher-level code? If so, would
rollback() be a better name?
Oh, no, no. No way. I don't want to push someone else's responsibility on
Directory. This abort() is merely a shortcut.
Let's go with a usage example:
Here's FieldsWriter.java with LUCENE-2814 applied (skipping irrelevant parts) -

Now, the same, with abort() - https://gist.github.com/746367

> Project: Lucene - Java
> Issue Type: Improvement
> Reporter: Earwin Burrfoot
>
> I'd like to see abort() method on IndexOutput that silently (no exceptions)
> closes IO and then does silent papaDir.deleteFile(this.fileName()).
> This will simplify a bunch of error recovery code for IndexWriter and
> friends, but constitutes an API backcompat break.
> What do you think?
