This patchset reworks structures that represent SQL triggers to inherent
them from base trigger class. It is an important step to introduce a
LUA persistent trigger in Tarantool as well as to support SQL triggers
evaluation on the server side.
In scope of this patchset the _triggers space was extended with a new fields.
The _trigger space updated format is:
[<name> STRING, <space_id> UINT32, <opts> MAP, <language> STR,
<type> STR, <event_manipulation> STR,
<action_timing> STR, <code> STR]
Now trigger is produced mostly by tuple-based metadata definition instead of
naive SQL request parsing.
Branch: http://github.com/tarantool/tarantool/tree/kshch/gh-4343-persistent-triggers
Issue: https://github.com/tarantool/tarantool/issues/4343
Kirill Shcherbatov (9):
sql: remove redundant pointer in TriggerStep

The trigger pointer in the sql_trigger structure is a dead code
now, so it could be deleted.
Needed for #4343

Renamed struct trigger to struct lua_trigger because the 'trigger'
name is too general. Currently Tarantool has non-persistent
AppServer Lua triggers represented with 'trigger' structure so as
SQL-specific persistent trigger object named 'sql_trigger'.
In scope of this patchset we going to significantly rework
triggers subsystem and introduce a new base trigger class named
'trigger', so this name is be better to be released.

From: Kirill Shcherbatov @ 2019-10-14 16:03 UTC (permalink / raw)
To: tarantool-patches, tarantool-patches, kostja.osipov, korablev
This patch introduces a new trigger_event_manipulation enum
that describes a trigger event. This is the type of operation on
the associated space for which the trigger activates.
The value could be `INSERT` (a row was inserted), `DELETE`
(a row was deleted), or `UPDATE` (a row was modified).
Using the enum instead of sql-specific TK_ token identified is
an important step to introduce a trigger_def structure in
further patches.
Needed for #4343

This patch introduces a new trigger_action_timing enum
that describes a moment when the trigger activates: before or
after the triggering event.
Using the enum instead of sql-specific TK_ token identified is
an important step to introduce a trigger_def structure in
further patches.
Needed for #4343

To: tarantool-patches, tarantool-patches, kostja.osipov, korablev
Using a rlist structure member to organize structures in a list
is typical practice in the Tarantool core; and reduces costs for
supporting and extending of an existent code.
With this refactoring using an universal trigger structure in
further patches would be simpler.
Needed for #4343

To: tarantool-patches, tarantool-patches, kostja.osipov, korablev
SQL grammar used to construct the sql_trigger object or to
generate a related VDBE instructions in a two functions with
a shared context: sql_trigger_begin and sql_trigger_end.
It used to be an AST compile or VDBE code generation in according
to parser::is_parse_only flag state - that is messy.
This patch reworks SQL rule a bit to call a function once, when
the whole trigger context is assembled to call the first function
that constructs AST or the second to emit VDBE code.
Needed for #4343.

From: Kirill Shcherbatov @ 2019-10-14 16:03 UTC (permalink / raw)
To: tarantool-patches, tarantool-patches, kostja.osipov, korablev
Introduced a new sql_trigger_expr to aggregate all
sql_triger-related ASTs. This allows to rework
sql_trigger_compile function in further patches to return
sql_trigger_expr object instead of the complete trigger
object.
It is an important step of refactoring, because we are going
to construct trigger and trigger_def objects universally by
information that will be defined in the _trigger space.
Needed for #4343

To: tarantool-patches, tarantool-patches, kostja.osipov, korablev
This patch reworks a _trigger system space to make it
useful not only for sql triggers definitions.
The format of the updated system space is
_trigger (space id = 328)
[<name> STRING, <space_id> UINT32, <opts> MAP, <language> STR,
<type> STR, <event_manipulation> STR,
<action_timing> STR, <code> STR]
After insertion into this space, a new instance describing trigger
object is created using language-dependent constructor.
This volumerous refactoring is an initial step for further
introduction of persistent triggers in Lua.
Needed for #4343

To be honest, I don't clearly understand what plan you are following now.
I remember that you wrote RFC, what status does it have now? Is it accepted
and this preparation is done in accordance with it? If so, let's firstly
push RFC. In case RFC is not approved or is changed, it would be nice to
see more detailed rationale for these patches..
Personally I've already said (see [dev] [rfc] Persistent triggers in Tarantool
thread) that I do not support idea of storing both Lua and SQL trigger's
metadata in one space.

Well, we can not reach the point not only because we have
different opinions, but because the discussion is so slow.
The reason to store all persistent objects of the same type in the
same space is that Tarantool is designed as a multiple frontend
system. I.e. tomorrow there may be another front end, not just Lua
or SQL, and one doesn't want to have a separate table for each
front end.
If the trigger timing, action type, definer, setuid and other
semantics is the same, and only the language is different, then
why duplicate the space? Whenever we add a new property common to
all triggers (e.g. persist enabled/disabled), we'll have to do
extra work.

Having said that, I should note that I mentioned earlier that I
don't think this feature is a high priority work.

It is not slow, it just gets stuck..

Let's be objective: how close we are to introduce new language in
Tarantool? Is there any demand for new language at all?

The thing is they are not the same. In fact, set of Lua and SQL trigger's
features are quite different. In Lua trigger timing can be one of
on_replace or before_replace, meanwhile in SQL trigger timing is one of
BEFORE/AFTER/INSTEAD replace; In Lua action event is replace, whereas in SQL
it can be INSERT/DELETE/UPDATE; FOR EACH ROW/STATEMENT action in SQL, and
only FOR EACH ROW is available in Lua.

it is one of the tenets of the design. Should it be broken now
just because it feels like it won't happen? I think it's a way
broader question than the scope of this patch.

Right, so it's different values (today) of properties, but the properties
are largely the same.
May I want to define a statement-level trigger in Lua in future?
Why not?
What are the benefits of having a separate table?

Okay, let's enumerate all possible properties of _trigger space (I've taken
version from the last RFC):
- name (both have)
- func_id (only Lua)
- space_id (both have)
- type (means one of replace/connection/auth etc; only Lua)
- event (only SQL)
- action_time (SQL and Lua have sets of timings which don't intersect)
- action (only SQL)
So there are only two features in common now: name and space id.

We don't have to manage and validate options that in fact are reasonable
only for SQL or Lua triggers.

If there will be persistent lua triggers, would it be possible to
drop them from SQL? With what construct? What will be their name
space (same name space as SQL triggers, or a distinct names space)?
Case sensitivity?

IMHO there should be no opportunity to drop Lua NoSQL triggers from SQL;
they should share different namespaces (as it happens now). The reason
is that SQL triggers will be implemented as NoSQL on_replace triggers
under the hood.

I need to mention that I didn't followed this outdated proposal in the
refactoring that we are discussing.
<name> STRING (both have)
<space_id> UINT32 (both have)
<opts> MAP (non of them for now, legacy, but potentially usefull)
<language> STR (both have)
<type> STR (both have; currently 'replace' type only - replace trigger;
perhaps we would like to support some different trigger types)
<event_manipulation> STR {"DELETE", "UPDATE", "INSERT" --
SQL only? - but it is possible to support it in Lua also}
<action_timing> STR {"BEFORE", "AFTER" - both have}
<code> STR (both have)

This is true for non-persistent triggers. What if we ever decide
to persist Lua triggers?

Why there should be any difference between them? Persisted Lua triggers
have nothing in common with SQL triggers. They are just parsed and re-created
after restart. Then they behave as normal (in-memory) NoSQL triggers.

Strictly speaking, this relates only to NoSQL triggers.

How is this supposed to be supported in Lua? For NoSQL triggers only "replace"
event is valid, which obviously is non of delete, update or insert.

AFTER is not the same as on_replace; SQL also has INSTEAD.

You format missing func_id which is required for NoSQL triggers and action
(FOR EACH STMT/ROW) which is valid for SQL only.

Lua has Lua triggers, right. But they have old and new tuple.
As you know,
INSERT = REPLACE(old=NULL, new)
DELETE = REPLACE(old, new=NULL)
UPDATE = REPLACE(old, new)
So formally we may use such terminology and support corresponding
trigger_def-based if(s) if we like it.
On the other hand some options could be banned for some engines.

Yes, unfortunately INSTEAD OF is a different thing. And I test it in trigger_def_check
helper.

We don't have to take a reference to function object by id, it is messy.
Let's better assemble own object using body field.

Should they be "visible" to SQL? They certainly have effect on SQL
tables. If they are visible, should it be possible to enable,
disable, drop or modify them? If yes, what SQL syntax do you
suggest? If you suggest to use the same syntax as for SQL
triggers, the issue of trigger namespace arises.

Hi!
JFY, I agree with Kirill and Kostja. Triggers are
triggers, regardless of their language. If something is
not yet supported in box triggers, it will be supported
later. We will have much more trouble with managing two
tables, than in having to validate its tuples more
rigorously. After all, tuple validation will happen just
in alter.cc and only one time. I don't see why is it such
a problem, to just validate a tuple. While having two
tables will affect the whole lifetime of a space.

this is actually quite unfortunate, the trigger name is general
because it is any kind of trigger, it is not only used in Lua.
Just look at the scope of your patch, it's tree-wide.
I think the old name was good.
Besides, renaming the structure without renaming all of the api to
match is faux pas.

This is sql_trigger_event if we talk about SQL triggers only, or
box_trigger_event if we talk about any kind of database trigger.
Similarly, if we talk about sql_triggers only, it's
sql_trigger_def. If you wish to define a general-purpose trigger
object, for SQL and Lua, it's box_trigger_def.

This is a fine change, but sql_trigger could simply inherit from
struct trigger, and get the swap / add/remove api from it.

I agree with this inheritance path, but it's incomplete
sql_trigger inherits from box_trigger which inherits from
core/trigger.

I agree with the implementation approach, given that we want
persistent Lua triggers, which we hardly do (but we do want SQL
triggers to be fired on NoSQL events, otherwise PeterG rightfully
would claim that Tarantool SQL violates relational tenets by Codd).
I think you should extract this part into an own series and split
it up - it's the most critical piece of the change.
BTW, I thought of another reason to do triggers in Lua and SQL in
a single space: this is how we dealt with persistent functions,
and it worked well. When we talk about backends in Tarantool, we
should not forget about C backend, and whatever other language it
allows to bridge with.
