Subject [jira] [Commented] (DERBY-5886) FILE_CANNOT_REMOVE_FILE exception prints garbage.
Date Fri, 14 Sep 2012 18:38:08 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5886?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13456020#comment-13456020
] 

Dag H. Wanvik commented on DERBY-5886:
--------------------------------------

Note that File#delete does not throw IOException, it only returns false if a file can't be
deleted, so maybe that's why the second argument is (inadvertently?) omitted from the two
usages in EncryptData and RFResource.

Java 7 offers the method java.nio.file.Files#delete(path) which does throw IOException and
others if the file can't be deleted. http://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#delete(java.nio.file.Path),
so going forward we may want to use that method so get more precise diagnostics.

> SQLState.FILE_CANNOT_REMOVE_FILE maps to a message which has 2 arguments. This SQLState
is used many times. It is variously given 1, 2, or 3 arguments. It's unclear whether we need
multiple messages here or whether a single message could be pressed into service for all cases.
As it is, some of these invocations are going to generate confusing garbage for the user.
This SQLState is used in the following classes:
> java/engine/org/apache/derby/impl/store/raw/data/EncryptData.java
> java/engine/org/apache/derby/impl/store/raw/data/RAFContainer.java
> java/engine/org/apache/derby/impl/store/raw/data/RFResource.java
