Hey,
ok I know that I'm brand new with your source, but can you please explain
me, why the Log object is configuring the database in the open method of
Log?
Shouldn't this code not be within the database class where you check all
the other database properties?
Ok I've a first solution - I think very dirty.
I justed added a new property
filesreadonly=true
If this property is set added the following code in the Log.open()
if (pProperties.isPropertyTrue("readonly")) {
bReadOnly = true;
dDatabase.setReadOnly();
if (cCache != null) {
cCache.open(true);
}
reopenAllTextCaches();
bRestoring = true;
ScriptRunner.runScript(dDatabase, sFileScript, logType);
bRestoring = false;
return false;
}
// akede@users - patch Files readonly (e.G. on a CD)
if (pProperties.isPropertyTrue("filesreadonly")) {
bReadOnly = true; // The log should be read only
//dDatabase.setReadOnly(); // The database should be
possible to be modified
if (cCache != null) {
cCache.open(true);
}
reopenAllTextCaches();
bRestoring = true;
ScriptRunner.runScript(dDatabase, sFileScript, logType);
bRestoring = false;
return false;
}
// end: patch akede
Cause the Log writer checks during the write if bReadOnly is true he will
not try to write anything to the disc. And because the Log checks the
bReadOnly on the close() too, there will also no script or cached file be
written.
As I said above, it was for me a little bit confusing that a Log class is
responsible for reading and writing the database and not the database
class. So I was first confused why i worked till I understood that the
Log.bReadOnly flag in the Log class only affects the files and not the
database.bReadOnly only takes care about the statements and JDBC calls. If
the database object would be asked for veryfing that scripts can be written
or not, my patch won't work.
I'm looking forward to any comments.
Alex
PS: I changed also the HsqlDatabaseProperties.java but just to set the
default value of filesreadonly to false.
