Subject [jira] Updated: (DERBY-1241) When booting a database under security manager, boot may fail with message java.sql.SQLException: Java exception: 'access denied (java.io.FilePermission for logmirror.ctrl if database was not shutdown cleanly after previous access

     [ http://issues.apache.org/jira/browse/DERBY-1241?page=all ]

Myrna van Lunteren updated DERBY-1241:
--------------------------------------

    Attachment: DERBY-1421_101_20060802.diff

Attaching the promised 10.1 patch. 

This is the merge comamnd I couldn't get to work: 
svn merge -r 427795:427796 https://svn.apache.org/repos/asf/derby/code/trunk

It gave me an error:

svn: REPORT request failed on '/repos/asf/!svn/vcc/default'
svn:
Cannot replace a directory from within

with the patched 10.1.3.1 insane jars derbyall ran with only 1 failed test: JapanCodeConversion
(because of using a jre rather than jdk path).

> When booting a database under security manager,  boot may  fail with message java.sql.SQLException:
Java exception: 'access denied (java.io.FilePermission   for  logmirror.ctrl   if database
was not shutdown cleanly after  previous access

is invalid  on log factory boot method and cause this failure on boot if  the database was
not shutdown cleanly.  The reproduction  (see comment) shows that can happens after database
creation.

> By looking at the stack it looks like log/logmirror.ctrl  is not getting accessed in
the privileged block at  line 2940 in LogToFile.java.
> if (checkpointInstant == LogCounter.INVALID_LOG_INSTANT &&                  
  getMirrorControlFileName().exists())
> Not sure how you got checkpointInstant to be INVALID , may be your test program might
have exited before a first valid checkpoint. Any one fixing this bugs should make sure that
is the case.
> In any case  call to exists should have been privExists(getMirrorControlFileName()).
> Please file a Jira entry  with information on how to reproduce this bug.
