Roll back Charlie's constructor patch. It's an admirable idea but it just adds too much unwieldy boilerplate to large records, and neither of us like the idea of on/off switches. We'll just have to construct by hand.

Charlie's patch to generate field-instantiating constructors for records that do not have existing (non-generated) constructors. Generated, nullable or default-value'd fields are ignored by the constructor.

We'd accidentally conflated SQL expressions and SQL clauses into the one interface SQLExpressionsf, which would allow statements like 'FooRecord.BAR.add(FooRecord.getKey(1))' to compile erroneously. Let SQLExpressions and QueryClauses both be subclasses of a new type SQLFragment, and let our ExpressionVisitor be a FragmentVisitor.

Depot's caching strategy relies on every clause and all its subexpressions constructing deterministic toString()'s. We do it by requesting that each function implementation returns an identifying string. We could use StringUtil.shortClassName() as things stand now, but I think perhaps MDB wants to get rid of the named classes.

SQLOperator gets the axe.

I'm not going all the way down this path today, but now that we've hidden the
...
implementation of operators and expressions, we can go the whole nine yards and
eliminate the named classes entirely (except in cases where we need them for
multiple dispatch by the visitors). Demonstrated this neatness with And and Or.

We're having an existential crisis. There are two exists() methods.

Added Ops.exists().
2009-09-10 03:05:34 +00:00
7a350474f5
Added exists() as well as a static add() and mul() for times when it seems
...
weird to use those fluently. Might also add div() and sub() but I'm currently
wondering why those have varags constructors Div(SQLExpression... values). What
does foo / bar / baz mean exactly? That's a rhetorical question, division is
left associative, but it's still weird and too non-obvious IMO. foo - bar - baz
is also wonky.
2009-09-10 02:56:21 +00:00

Another spot where we need to return non-specific types.
2009-09-10 02:23:24 +00:00

Well, OK. We're going to take the pain and break binary compatibility and use
...
thsi opportunity to move a whole heap of stuff into impl that doesn't really
need to be visible to external parties. We're changing the return value of all
expression creating factory classes to SQLExpression or FluentExp because those
expose all the functionality one might need on the returned values and there's
otherwise no value to be had getting an And() or a LiteralExp() and a downside
of preventing us from replacing the implementation of those expressions without
breaking binary compatibility.
I hemmed a bit about everything in depot.operator. In theory everything there
is available via a combination of Exps and FluentExp but in practice Whirled
uses a ton of those classes directly (whre a ton is defined as 64 imports of
classes in depot.operator). Perhaps I'll go on a cleanup jihad there and then
move all that to impl as well.
The rabbit holes, they always go deep.

These need to return FunctionExp to be binary compatible. Let this be a
...
reminder why it can be useful not to return the most specific type possible
from a method, but rather a more general supertype that allows us to change the
internals of the method without losing binary compatibility.

It turns out PostgreSQL supports LN(exp) and LOG(exp) in double precision, but not LOG(base, exp). So we're adding an explicit LOG10. I wonder how useful the two-argument one is... maybe we should delete it.

Deprecate FunctionExp in favour of explicit support for many common SQL functions, whose convenience factory methods reside in com.samskivert.depot.Funs. The EpochSeconds class is also deprecated in favour of Funs.dateEpoch().

Connection.isClosed() is new in 1.6 and Connection.close() is a no-op if the connection is already closed, so let's go for brevity here and save people from having to have 1.6-specific JDBC drivers.

Charlie's commit patch; if we're not in the auto-commit state, let Depot explicitly commit its operations. If we add transaction awareness to Depot in some future, this behaviour might become more subtle.
