Par Winzell c41534c7e6 We need these two fellows for the previous patch to make sense. 2008-12-31 00:59:28 +00:00
Par Winzell 0ccd8bdb82 Extend our Index annotation to accept a 'complex' attribute. If an index ixFoo is marked complex for a given record, Depot will call the static method ixFooDefinition on that record class and expect a List<Tuple<SQLExpression, OrderBy.Order>> return value.
The purpose of all this is to create function (or expression, rather) indexes, which PostgreSQL does quite happily.

Michael Bayne e3aed39330 Document our thrown exceptions. 2008-12-16 00:00:52 +00:00
Par Winzell 44fd01cc2d Switch to nulls here, too, making migration work right for HSQLDB. 2008-12-10 23:02:34 +00:00
Par Winzell b3cb1d6214 Cut and paste error. 2008-12-10 21:09:56 +00:00
Michael Bayne 50d31cfcc5 Unused import nixage. 2008-12-10 20:05:34 +00:00
Par Winzell f0f08f9516 More HSQL support:
- HSQL doesn't have full text search, so we just OR up a bunch of LIKE conditions to catch any and all matches. This is not efficient, but it'll do just fine for things like unit tests and development work.
 - HSQL doesn't have & and |, it calls them BITAND and BITOR.
 - HSQL doesn't have MySQL's unix_timestamp() or a way to get an 'epoch' from a date like PostgreSQL, so we count the number of seconds since 1970-01-01. I have not investigated to make sure this is exact, but it should at least be internally consistent.
 - HSQL has a very neat list of data types that (no surprise) map very well to Java types.

Par Winzell 96dfa3ca04 Break up the function that generates ColumnDefinitions for our fields and pass around a mutable instance of that object so as to give subclasses more freedom to do whatever weird stuff they need to to generate SQL for all the incompatible dialects out there. This is not elegant, and I feel this code along with ColumnDefinition and some of DatabaseLiaison, should pperhaps find a new home in the SQLBuilder structure. 2008-12-09 23:20:14 +00:00
Par Winzell b9bb84d3af Cope with the new ColumnDefinition. 2008-12-09 23:18:17 +00:00
Par Winzell 7eaaea15e7 Instead of enumerating columns for which values will be auto-generated and supplying magical DEFAULT arguments for them, simply don't include those columns in the insert. 2008-12-09 23:00:50 +00:00
Par Winzell cc07817238 Remove an ancient TODO: Get rid of SELECT FOR UPDATE and instead locklessly claim the next available primary key value. 2008-12-09 22:56:55 +00:00
Par Winzell 817857d20e HSQL doesn't think 'false' is a proper condition in a DELETE statement, and I suppose it has a point. This should always work. 2008-12-09 20:28:20 +00:00
Michael Bayne 14a85d0de6 Differentiate between explicit queries and decomposed queries. 2008-11-25 22:02:15 +00:00
Michael Bayne 8ab95ec10e Unconcretification of QueryClause. I concreted it a while back when it did
something and then those needs went away and now it's just a marker that
differentiates arbitrary SQLExpression instances from those that represent
clauses of a query.
2008-11-25 20:53:33 +00:00
Michael Bayne 8fec576663 Moved things that are not part of the Depot public API into an impl package.
Also moved WhereClause into depot.clause since it really wanted to be there.
2008-11-25 20:44:22 +00:00
Michael Bayne 980be19918 Unused import pruning and other cleaning. 2008-11-25 20:14:09 +00:00
Michael Bayne 0b439978fb Stubbed out Depot support for HSQLDB. This also doesn't work yet but will some
day be made to work and enable more sophisticated unit testing of Depot and
systems that use Depot.
2008-11-25 20:13:43 +00:00
Michael Bayne bc44c4e58e A cache adapter for testing. 2008-11-25 00:57:22 +00:00
Michael Bayne 9e2dbeb174 Finished collection caching implementation. Our databases will shortly breath a
great sigh of relief.
2008-11-25 00:57:04 +00:00
Michael Bayne ae34697c8d KeySet is going to get stuffed into the cache, so we're making it more memory
efficient.

Also switched from Collection to Iterable in some internal spots where we don't
need anything other than an iterator. I wanted to push this all the way out to
DepotRepository but ran into some snags. I'm leaving in this change in case I
feel like desnaggling the external bits later.
2008-11-24 22:05:04 +00:00
Michael Bayne ae414006bc These don't *really* override anything so we can't mark them as such as JDK 1.5
will do le freak out.
2008-11-21 06:30:32 +00:00
Michael Bayne f6339978bf Missed a spot. 2008-11-21 06:11:57 +00:00
Michael Bayne 475200849c Extract query and record cache tracking into parent. 2008-11-21 03:19:44 +00:00
Michael Bayne e347f4ac17 More toString()ery. Changed KeyUtil to DepotUtil so I could jam some more
useful stuff in it.
2008-11-21 03:15:47 +00:00
Michael Bayne e98ad09588 If loadAll() can return its results entirely from the cache before invoke(),
have it do so. Down to the last couple of steps for collection caching.
2008-11-21 02:50:16 +00:00
Michael Bayne 22c086f64e Extracted findAllKeys() query into a helper class, made it possible for Query
to request a read-write connection.
2008-11-21 02:30:08 +00:00
Michael Bayne 3cf711e083 More toString()s. 2008-11-21 02:04:07 +00:00
Michael Bayne 9880ff326c A whole bunch of revampery on the way to collection caching, including some
basic stats reporting and query and cache logging.

PersistenceContext no longer sticks its nose so deeply into the business of
Query and Modifier. It just passes itself along and allows them to do any cache
activity they need during their normal execution. The one situation where we
keep our nose in their business is to allow a Query to return a result from the
cache before it is even invoked so that we can avoid requesting a database
connection if we won't ever need one.

Michael Bayne 5f26eb28c9 Fixed sed error. 2008-11-20 00:16:57 +00:00
Michael Bayne 566ebcf7f9 Only release the connection if we didn't report it as failed. 2008-11-17 21:55:02 +00:00
Michael Bayne 1f86dbd9c4 Google Collectivised. 2008-11-16 18:31:25 +00:00
Michael Bayne 9c0dbb5b47 Fixed up packages. 2008-11-16 08:01:19 +00:00
Michael Bayne c60181a484 We need a GWT module. 2008-11-16 07:53:22 +00:00
Michael Bayne 7a23a6bd49 Copy the tests over. I couldn't migrate these with the rest of the SVN
migration because svndumpfilter is a royal pain in my ass.
2008-11-16 07:30:20 +00:00
Michael Bayne b32b4eecc3 Updated the source headers and added the license file. 2008-11-16 06:17:45 +00:00
Michael Bayne 40c1480039 More tidying, added Javadoc overview. 2008-11-16 06:08:56 +00:00
Michael Bayne 745c380e8d Repackage Depot as com.samskivert.depot as it is now a standalone library.
We're also going to allow ourselves the luxury of a Google Collections
dependency.
2008-11-16 05:59:28 +00:00
Michael Bayne 6959383b6c Unified Query and Modifier under Operation which cleans up some niggles in
PersistenceContext.
2008-11-13 23:35:12 +00:00
Par Winzell f653e59a66 That was broken code-in-progress and not meant to be commnitted. 2008-11-05 00:19:59 +00:00
Par Winzell 49391b1995 When we reinitialize the Throttle with a smaller number of allowed operations within a time period, we should preserve the oldest rather than the newest ones, or we'll most likely be in immediate and unfair violation of the limit. 2008-11-05 00:18:21 +00:00
Par Winzell bac0348951 Change these hard-coded defaults. Should also be made configurable. 2008-11-04 19:20:33 +00:00
Michael Bayne 05f499736e Nixed unused import, commented out others that go with commented out code. 2008-11-01 05:39:27 +00:00
Michael Bayne 8ec25c5a6d Make the 1.5 compiler happy. 2008-10-31 00:42:53 +00:00
Michael Bayne 2b8bc0c97f When we can switch entirely to 1.6 we can use Postgres's value = any(?::int[])
form to pass as many damned keys we want in a giant array. At that time we can
nix all the >32,768 key fiddly business.
2008-10-31 00:17:36 +00:00
Michael Bayne ec76d4d29f Oops, avoid introducing a bug when nulls == zeros == values.length. We want to
return null in that case.
2008-10-24 05:18:50 +00:00
Michael Bayne 2309c490f7 Compromise on our 0 == null stance for primary key columns. See the code
comments for further details.
2008-10-24 05:13:28 +00:00
Michael Bayne ba97743754 Make sure we use the up to date metadata when doing our stale column check. 2008-10-22 01:09:22 +00:00
Michael Bayne 19287550f4 More javadoc cleanup. 2008-09-30 00:23:57 +00:00
Michael Bayne 4c94296b67 Javadoc fixes. 2008-09-30 00:12:08 +00:00
Michael Bayne fee6be6c2d Added support for data migrations, which are run after all schema migrations
have been run and are also coordinated between disparate processes by an
in-database lock system.
