The goal of this patch set is to teach vinyl operate on key statements
like on regular tuples so that we can avoid filling tuples read from
secondary index runs with nulls (aka tuple surrogate). This is required
to implement multikey indexes in vinyl.
The first seven patches are preparatory - they do some cleanup that
stand on the way and can probably be applied even if the rest of the
patch set is rejected. The real work is done by the last 5 patches,
which should be reviewed with scrutiny. I'm far not sure this is the
right way to go, but I've failed to find a better solution so far.
https://github.com/tarantool/tarantool/commits/dv/vy-dont-store-nulls-in-sk
Vladimir Davydov (12):
vinyl: use vy_lsm_env::empty_key where appropriate
vinyl: make vy_tuple_delete static
key_def: cleanup virtual function initialization
key_def: move cmp and hash functions declarations to key_def.h
vinyl: move vy_tuple_key_contains_null to generic code
vinyl: move vy_key_dup to generic code
vinyl: sanitize full/empty key stmt detection
vinyl: remove optimized comparators
vinyl: introduce statement environment
vinyl: rename key stmt construction routine
vinyl: don't use IPROTO_SELECT type for key statements
vinyl: do not fill secondary tuples with nulls when decoded

No need to allocate an empty key during DDL - we already have one
preallocated in vy_lsm_env.

- Rename key_def_set_cmp to key_def_func_set, because it sets not only
comparators these days.
- Rename tuple_extract_key_set to tuple_extract_key_func_set to match
tuple_hash_func_set.
- Introduce tuple_compare_func_set and use it instead of setting
comparators explicitly in key_def.c.

Most of them are already there - for instance see see tuple_extract_key
and tuple_compare. Let's move the rest there too for consistency.

The function doesn't require any knowledge of vinyl statement layout and
can work on regular tuples. Let's rename it to tuple_key_contains_null,
move its implementation to tuple_extract_key.cc, and declare it in
key_def.h, as we do with other similar functions.

This helper function has nothing to do with vinyl - it's simply
duplicates a msgpack array. Let's move it to tuple.c and rename
it to key_dup.

Historically, we use tuple_field_count to check whether a statement
represents an empty key (match all) or a full key (point lookup): if
the number of fields in a tuple is greater than or equal to the number
of parts in a key definition, it can be used as a full key; if the
number of fields is zero, then the statement represents an empty key.
While this used to be correct not so long ago, appearance of JSON
indexes changed the rules of the game: now a tuple can have nested
indexed fields so that the same field number appears in the key
definition multiple times. This means tuple_field_count can be less
than the number of key parts and hence the full key check won't work
for a statement representing a tuple.
Actually, any tuple in vinyl can be used as a full key as it has all
key parts by definition, there's no need to use tuple_field_count for
such statements - we only need to do that for statements representing
keys. Keeping that in mind, let's introduce helpers for checking
whether a statement can be used as a full/empty key and use them
throughout the code.

A vinyl statement (vy_stmt struct) may represent either a tuple or a
key. We differentiate between the two kinds by statement type - we use
SELECT for keys and other types for tuples. This was done that way so
that we could pass both tuples and keys to a read iterator as a search
key. To avoid branching in comparators when the types of compared
statements are known in advance, we provide several comparators, each of
which expects certain statement types, e.g. a tuple and a key. Actually,
such a micro optimization looks like an overkill, because a typical
comparator is called by a function pointer and has a lot of comparisons
in the code, see tuple_compare_slowpath for instance. Eliminating one
branch will hardly make the code perform better. At the same time, it
makes the code more difficult to write. Besides, once we remove nils
from statements read from disk (aka surrogate tuples), which is required
to support multikey index, the number of places where types of compared
statements are known will diminish drastically. That said, let's remove
optimized comparators and always use vy_stmt_compare, which checks types
of compared statements and calls the appropriate comparator.

This will allow us to determine a statement type (key or tuple)
by checking its format against key_format.

To: kostja; +Cc: tarantool-patches
Currently, it's called vy_stmt_new_select, but soon a key statement will
be allowed to have any type, not just IPROTO_SELECT. So let's rename it
to vy_stmt_new_key. Let's also rename the wrapper vy_key_from_msgpack to
vy_stmt_new_key_from_array, because its key feature is that in contrast
to vy_stmt_new_key it takes a msgpack array instead of key data + part
count.

To differentiate between key and tuple statements in comparators, we set
IPROTO_SELECT type for key statements. As a result, we can't use key
statements in the run iterator directly although secondary index runs do
store statements in key format. Instead we create surrogate tuples
filling missing fields with NULLs. This won't play nicely with multikey
indexes so we need to teach iterators to deal with statements in key
format. The first step in this direction is dropping IPROTO_SELECT and
starting to identify key statements by format instead.

In contrast to a primary index, which stores full tuples, secondary
indexes only store extended (secondary + primary) keys on disk. To make
them look like tuples, we fill missing fields with nulls (aka tuple
surrogate). This isn't going to work nicely with multikey indexes
though: how would you make a surrogate array from a key? We could
special-case multikey index handling, but that would look cumbersome.
So this patch removes nulls from secondary tuples restored from disk
altogether. To achieve that, it's enough to use key_format for them -
then the comparators will detect that it's actually a key, not a tuple
and use the appropriate primitive.

I don't understand the purpose of this patch yet.

This is OK to push, but please don't push it until it's really
needed (e.g. until you get OK to push on a patch which uses it).

OK to push, but the same comment as for the previous patch
applies, I don't think this patch is useful without the rest.

I like the new names, vy_stmt_new_key_from_array - maybe
vy_stmt_new_key_from_msgpack after all?

It's amazing how simple this patch is, it's OK to push provided we

Because there's no place for msgpack helpers inside tarantool. Besides,
other functions operating on raw keys (which are msgpack arrays) have
key_ prefix, e.g. key_compare.

OK. I just wanted to expel it from vinyl code so as to avoid confusion
between vinyl key statement and raw key msgpack.

Subject: [PATCH] key_def: cleanup virtual function initialization
- Rename key_def_set_cmp to key_def_set_func, because it sets not only
comparators these days.
- Rename tuple_hash_func_set and tuple_extract_key_set to
key_def_set_hash_func and key_def_set_extract_func, because it's more
like subject-verb-object naming convention used throughout the code.
- Introduce key_def_set_compare_func and use it instead of setting
comparators explicitly in key_def.c.

Well, it's just a technical debt left from the json index patch.
In fact, the code may be buggy/suboptimal without this patch. E.g.
tuple cache heavily relays on whether the passed statement is a full
or a partial key. If it fails to detect it, it won't store a chain
when it should. We used to use tuple_field_count to check whether
a tuple represents a full key or not:
if (tuple_field_count(tuple) >= cmp_def->part_count)
/* full key */
With json indexes this isn't correct anymore, because the same field may
be indexed multiple times, e.g. [2].path1 and [2].path2. Due to this,
the full key check may fail for a full tuple, which is obviously wrong
although a full tuple must have all key parts defined. This patch makes
those check work only tuples representing keys while assuming that all
tuples may be used as full keys. And it wraps it inside a pair of helper
functions.

But vy_stmt_new_key also takes msgpack so we'd have two functions both
taking msgpack, called vy_stmt_new_key and vy_stmt_new_key_from_msgpack.
Looks confusing IMO. Not that it really matters to me. I can rename it
if you think it's OK.
