Please try out 1.1 or the cvs head and reopen the bug if you have issues with that version. You have done significant work on this, and I would be interested to know if this issue exists in 1.1 core. If you do find it, please submit the patch in diff -u format (I use eclipse, it's really easy) and I will expedite the commit. If you were to be able to create a junit first, that would be great. |
I run Xindice under Windows 98 and use this classpath: D:\JDK\lib\tools.jar (tried at first and last position of the classpath) D:\XINDICE\Java\Lib\xmldb.jar D:\XINDICE\Java\Lib\XIndice.jar D:\XINDICE\Java\Lib\xalan-2.0.1.jar D:\XINDICE\Java\Lib\XERCES-1.4.3.jar D:\XINDICE\Java\Lib\openorb-1.2.0.jar D:\XINDICE\Java\Lib\ANT-1.4.1.jar + JSDK 1.3.1 or JDK 1.4.01 (tried both) when I start the server with startup.bat, my screen is filled with exceptions like these: DEBUG> java.lang.IndexOutOfBoundsException at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:89) at org.apache.xindice.core.filer.Paged$Page.streamTo(Paged.java:992) at org.apache.xindice.core.filer.Paged.readValue(Paged.java:163) at org.apache.xindice.core.filer.BTreeFiler.readRecord(BTreeFiler.java:131) at org.apache.xindice.core.Collection.getDocument(Collection.java:714) at org.apache.xindice.core.Collection.putDocument(Collection.java:624) at org.apache.xindice.core.Collection.putObject(Collection.java:795) at org.apache.xindice.core.Collection.setObject(Collection.java:807) at org.apache.xindice.core.SystemCollection.saveSymbols (SystemCollection.java:202) at org.apache.xindice.core.SystemCollection.loadSymbols (SystemCollection.java:185) at org.apache.xindice.core.Collection.setConfig(Collection.java:175) at org.apache.xindice.core.CollectionManager$1.process (CollectionManager.java:96) at org.apache.xindice.util.Configuration.processChildren(Configuration.java:684) at org.apache.xindice.core.CollectionManager.setConfig (CollectionManager.java:92) at org.apache.xindice.core.Collection.setConfig(Collection.java:216) at org.apache.xindice.core.SystemCollection.init(SystemCollection.java:155) at org.apache.xindice.core.Database.setConfig(Database.java:155) at org.apache.xindice.server.services.XindiceService.initialize (XindiceService.java:106) at org.apache.xindice.server.standard.StdServiceManager.addService (StdServiceManager.java:166) at org.apache.xindice.server.standard.StdServiceManager$1.process (StdServiceManager.java:104) at org.apache.xindice.util.Configuration.processChildren(Configuration.java:684) at org.apache.xindice.server.standard.StdServiceManager.setConfig (StdServiceManager.java:90) at org.apache.xindice.server.Kernel.loadAPI(Kernel.java:336) at org.apache.xindice.server.Kernel.<init>(Kernel.java:150) at org.apache.xindice.server.Kernel.<init>(Kernel.java:117) at org.apache.xindice.server.Xindice.main(Xindice.java:96) DEBUG> java.io.IOException: Negative seek offset at java.io.RandomAccessFile.seek(Native Method) at org.apache.xindice.core.filer.Paged$Page.read(Paged.java:921) at org.apache.xindice.core.filer.Paged.getPage(Paged.java:130) at org.apache.xindice.core.filer.Paged.getPage(Paged.java:144) at org.apache.xindice.core.filer.Paged.writeValue(Paged.java:207) at org.apache.xindice.core.filer.BTreeFiler.writeRecord(BTreeFiler.java:173) at org.apache.xindice.core.Collection.putDocument(Collection.java:629) at org.apache.xindice.core.Collection.putObject(Collection.java:795) at org.apache.xindice.core.Collection.setObject(Collection.java:807) at org.apache.xindice.core.SystemCollection.saveSymbols (SystemCollection.java:202) at org.apache.xindice.core.SystemCollection.loadSymbols (SystemCollection.java:185) at org.apache.xindice.core.Collection.setConfig(Collection.java:175) at org.apache.xindice.core.CollectionManager$1.process (CollectionManager.java:96) at org.apache.xindice.util.Configuration.processChildren(Configuration.java:684) at org.apache.xindice.core.CollectionManager.setConfig (CollectionManager.java:92) at org.apache.xindice.core.Collection.setConfig(Collection.java:216) at org.apache.xindice.core.SystemCollection.init(SystemCollection.java:155) at org.apache.xindice.core.Database.setConfig(Database.java:155) at org.apache.xindice.server.services.XindiceService.initialize (XindiceService.java:106) at org.apache.xindice.server.standard.StdServiceManager.addService (StdServiceManager.java:166) at org.apache.xindice.server.standard.StdServiceManager$1.process (StdServiceManager.java:104) at org.apache.xindice.util.Configuration.processChildren(Configuration.java:684) at org.apache.xindice.server.standard.StdServiceManager.setConfig (StdServiceManager.java:90) at org.apache.xindice.server.Kernel.loadAPI(Kernel.java:336) at org.apache.xindice.server.Kernel.<init>(Kernel.java:150) at org.apache.xindice.server.Kernel.<init>(Kernel.java:117) at org.apache.xindice.server.Xindice.main(Xindice.java:96) By editing the Xindice sources I added some messages to track a bit more my trouble and discovered that the readValue function in BTreeFiler::readRecord is the one who failed. public synchronized Record readRecord(Key key) throws DBException { checkOpened(); try { long pos = findValue(key); Page startPage = getPage(pos); Value v = readValue(startPage); BTreeFilerPageHeader sph = (BTreeFilerPageHeader)startPage.getPageHeader(); HashMap meta = new HashMap(2); meta.put(Record.CREATED, new Long(sph.getCreated())); meta.put(Record.MODIFIED, new Long(sph.getModified())); return new Record(key, v, meta); } catch ( BTreeNotFoundException b ) { } catch ( BTreeException b ) { throw b; } catch ( Exception e ) { org.apache.xindice.Debug.printStackTrace(e); } return null; } Here the steps: 1) the system ask for the pos of the key 'database.xml' and got the result 1. 2) then it asks for the startpage at this position: the page header he receive is '(pageNum: 1, keyPos: 64, dataPos: -262, offset: 8 192)' It's a sample, but these numbers are most of the time negative and appears to have no sense. 3) it calls the readValue function who fail, acting on a negative number this function should not use. However, even with theses troubles, the server is launched and creating a collection then adding a document is possible. Even queries seems then to work. but I have to say that when I stop the server with a: xindiceadmin shutdown -c /db I receive the following dump: org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 208 completed: Maybe at com.sun.corba.se.internal.iiop.IIOPConnection.purge_calls(IIOPConnect ion.java:438) at com.sun.corba.se.internal.iiop.ReaderThread.run(ReaderThread.java:70) ERROR : org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No Verify the Xindice server is running org.omg.CORBA.COMM_FAILURE: ERROR : org.omg.CORBA.COMM_FAILURE: vmcid: SUN mi nor code: 201 completed: No Verify the Xindice server is running vmcid: 0x0 m inor code: 0 completed: No at org.apache.xindice.tools.XMLTools.process(XMLTools.java:267) at org.apache.xindice.tools.XMLAdminTools.main(XMLAdminTools.java:89) and all data I may have stored during this session are lost. At the next restart of Xindice I will only find the collection system available. Marc.
