From 1287cdaf338c4f1b782985597de9358de534bbef Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Wed, 27 May 2015 16:25:32 -0700 Subject: [PATCH] Close 'out' consistently in ArchiveCommand.call Whether the output stream specified with setOutputStream() is closed by ArchiveCommand.call() is murky and inconsistent: - on success, it is closed - if an exception is encountered when writing the archive, it is closed - if an exception is encountered when calling createArchiveStream to open the archive, we forget to close it Close the output stream consistently to avoid leaks. Now that the inner try-with-resources doesn't have its own finally block, this allows us to merge the two try blocks. It would be even better to never close the output stream. That will involve more API changes to avoid silently breaking callers, so it is deferred to a later change.
