Hello! Thank you for review! New patch below. There won't be diff
between versions as I started this version before decided to save
this diff.

Hi! Thanks for the patch!
I see that Kostja slightly reviewed it and you did not
answer him, so I inlined here some of his comments to
agree/disagree with them.
See 8 comments below.

Ugh. You're including a header which ends with Int. Have you
thought what this Int means? It's not Integer.
Strictly speaking, I agree with him. Src/box/execute is not
an SQL internal file. It even uses SQLite public API to
fetch names and types. I guess, you should implement a getter
for ids list like
const struct stailq *
vdbe_auto_ids_list(const struct Vdbe *v);
Fixed.

What is the point of this == 0? Why are you comparing with an

I partially agree and I guess it is my fault that I am too harsh
about code style. You used here == 0 because stailq_empty()
returns an integer, but its name looks like a flag getter, so you
can use it as a boolean here.

I agree. He means 'vdbe_add_new_id'. And in such a
case it is evidently a part of Vdbe API, so put it into
vdbe.h with this signature:
int
vdbe_add_new_auto_id(struct Vdbe *vdbe, int64_t id);
Fixed.

6. If you have Vdbe, you do not need to store the list both in
Vdbe and sql_txn. Store it in Vdbe only.
Fixed.
7. Kostja said:
Why malloc?
It is understandable why malloc - txn after commit invalidates
the region memory. We neither can save ids on obuf directly
since while getting next id a yield is possible and the obuf
will be messed with another request. But guess I thought up a
solution. It is a bit tricky, so maybe it should be accounted
as a separate issue and this solved with malloc.
I propose to split txn_commit() into commit and region reset.
Txn_commit() goal is to write data to disk, not to destroy a
region. It saves us when a transaction is started and committed
by Vdbe. But what about autocommit transactions? I think, we
should get rid of autocommit transactions for Vdbe. Vdbe always
starts a transaction for DML and commits it, but without region
reset - it is a part of vdbe finalize routine (which already
exists actually).
This split of txn_commit logic allows to store anything on
a region during Vdbe work and not being afraid about a reset.

sql: return all generated ids via IPROTO
According to documentation some JDBC functions have an ability to
return all ids that were generated in executed INSERT statement.
This patch gives a way to implement such functionality.
