In this, the third and final installation of Andres' Introduction to Groovy series, you learn about how Groovy handles variable numbers of arguments, named parameters, currying, and more about Groovy operators. Including, some new operators.
Swing Fuse (actually just Fuse), is a framework designed to make it easier to create your own custom desktop components. In this article, Daniel Spiewak shows you how to get started and provides sample source code you can download.
Willam Louth shows how he uses JXInsight Probes to investigate probable performance issues with code bases that he is not familiar with. He also highlights possible pitfalls in creating a benchmark, as well as in the analysis of results.
# Large updates and deletes are now supported by buffering data to disk if required. The threshold is currently set to 100'000 bytes and can be changed using SET MAX_OPERATION_MEMORY or using by appending ;MAX_OPERATION_MEMORY=.. to the database URL. See also the docs.
# MVCC: now an exception is thrown when an application tries to change the MVCC setting while the database is already open.
# Referential integrity checks didn't lock the referenced table, and thus could read uncommitted rows of other connections. In that way the referential contraints could get violated (except when using MVCC).
# Renaming or dropping a user with a schema, or removing the admin property of that user made the schema inaccessible after re-opening the database. Fixed.
# The H2 Console now also support the command line option -ifExists when started from the Server tool, but only when connecting to H2 databases.
# Duplicate column names were not detected when renaming columns. Fixed.
# The console did not display multiple embedded spaces in text correctly. Fixed.
# Google Android support: use 'ant codeswitchAndroid' to switch the source code to Android.
# Values of type ARRAY are now sorted as in PostgreSQL.
# In the cluster mode, could not connect if only one server was running (last release only). Fixed.
# The performance of large CSV operations has been improved.
# Now using custom toString() for most JDBC objects and commands.
# Nested temporary views (SELECT * FROM (SELECT ...)) with parameters didn't work in some cases. Fixed.
# CSV: Using an empty field delimiter didn't work (a workaround was using char(0)). Fixed.
# A patch for Apache DDL Utils is available at https://issues.apache.org/jira/browse/DDLUTILS-185 # The default value for h2.emergencySpaceInitial is now 256 KB (to speed up creating encrypted databases)
# Eduardo Velasques has translated the H2 Console and the error messages to Brazilian Portuguese. Thanks a lot!
# Creating a table from GROUP_CONCAT didn't work if the data was longer than 255 characters

Re: H2 Database 1.0.62 Released
Unfortunately, there was a bug in version 1.0.62: some server settings didn't work. This has been fixed in version 1.0.63.
