We basically steal all the objects from their notmuch parents, therefore
they are completely under Ruby's gc control.
The order at which these objects are freed does not matter any more,
because destroying the database does not destroy all the children
objects, since they belong to Ruby now.

Currently Ruby data points directly to a notmuch object (e.g.
notmuch_database_t), since we don't need any extra data that is fine.
However, in the next commit we will need extra data, therefore we create
a new struct notmuch_rb_object_t wrapper which contains nothing but a
pointer to the current pointer (e.g. notmuch_database_t).
This struct is tied to the Ruby object, and is freed when the Ruby
object is freed by the garbage collector.
We do nothing with this wrapper, so no functionality should be changed.

The struct used to store the types (rb_data_type_t) contains a "data"
field where we can store whatever we want. I use that field to store a
pointer to the corresponding destroy function. For example
notmuch_rb_database_type contains a pointer to notmuch_database_destroy.
I cast that pointer as a notmuch_status_t (func*)(void *) and call
that function passing the internal object (e.g. notmuch_database_t).
Using the rb_data_type_t data we can call the correct notmuch destroy
function.
Therefore this:
ret = ((notmuch_status_t (*)(void *)) type->data) (nm_object);
Is effectively the same as this:
ret = notmuch_database_destroy (database);
The advantage of doing it this way is that much less code is necesary
since each rb_data_type_t has the corresponding destroy function stored
in it.

Virtually the whole ruby core moved from RData to RTypeData, let's do so
ourselves too.
Basically the information typically passed through Data_Wrap_Struct is
now stored in a struct rb_data_type_t (mark and free functions). This
has the advantage that more information can be easily added, like the
name of the type, a custom data ponter, and more.
Data_Wrap_Struct is replaced with TypedData_Wrap_Struct, and the
information is stored in a struct rb_data_type_t, rather than passed
as arguments.
Check_Type is replaced with Check_TypedStruct, which is a wrapper for
rb_check_typeddata (with casts).
#define Check_TypedStruct(v, t) \
rb_check_typeddata(RBIMPL_CAST((VALUE)(v)), (t))
We can use rb_check_typeddata directly, just like we use rb_data_object_get
directly.

This makes the code more maintainable and will help in further patches.
No functional changes.

We need a way to pass parameters to the indexing functionality on the
first index, not just on reindexing. The obvious place is in
notmuch_database_add_message. But since modifying the argument list
would break both API and ABI, we needed a new name.
I considered notmuch_database_add_message_with_params(), but the
functionality we're talking about doesn't always add a message. It
tries to index a specific file, possibly adding a message, but
possibly doing other things, like adding terms to an existing message,
or failing to deal with message objects entirely (e.g. because the
file didn't contain a message).
So i chose the function name notmuch_database_index_file.
I confess i'm a little concerned about confusing future notmuch
developers with the new name, since we already have a private
_notmuch_message_index_file function, and the two do rather different
things. But i think the added clarity for people linking against the
future libnotmuch and the capacity for using index parameters makes
this a worthwhile tradeoff. (that said, if anyone has another name
that they strongly prefer, i'd be happy to go with it)
This changeset also adjusts the tests so that we test whether the new,
preferred function returns bad values (since the deprecated function
just calls the new one).
We can keep the deprecated n_d_add_message function around as long as
we like, but at the next place where we're forced to break API or ABI
we can probably choose to drop the name relatively safely.
NOTE: there is probably more cleanup to do in the ruby and go bindings
to complete the deprecation directly. I don't know those languages
well enough to attempt a fix; i don't know how to test them; and i
don't know the culture around those languages about API additions or
deprecations.
Many of the external links found in the notmuch source can be resolved
using https instead of http. This changeset addresses as many as i
could find, without touching the e-mail corpus or expected outputs
found in tests.
The Ruby bindings were missing a way to get all the tags of the
database. Now you should be able to access this with the public
instance method `all_tags` of your database object.
Example of use:
notmuchdb = Notmuch::Database.new path, { :create => false,
:mode => Notmuch::MODE_READ_ONLY }
my_tags = notmuchdb.all_tags
my_tags.each { |tag|
print tag
}
my_tags.destroy!
Amended by db: improve error reporting, add test
Two new wrappers:
Notmuch::Database.find_message(id) => Notmuch::Message or nil
Notmuch::Database.find_message_by_filename(path) => Notmuch::Message or nil
Let the user destroy objects that she wants explicitly.
It's not possible to specify the order objects are garbage collected.
