@AndrewChubatiuk Thanks for the PR.
However, there are many changes and it appears that the SQL Alchemy version update includes unrelated refactorings...

We would like to accurately manage what modifications have been made with SQL Alchemy version upgrades, so could you please separate the PR? I apologize for asking you to do something troublesome, but it would be a great help if you could do that. thank you.

masayuki038 · 2023-12-22T09:47:24Z

@guidopetri @konnectr If it is okay to merge this from your perspective, please let me know. If so, I will consider this again.

AndrewChubatiuk · 2023-12-22T10:20:37Z

@masayuki038 besides:

removing -p option in ci
moving Alerts states to a separate Enum

other changes were required:

paginator changes were needed cause paginator function from flask-sqlachemy has changed
removing relative imports was related to issues in sqlalchemy
sort_query function was completely removed from sqlalchemy-utils, so it had to be replaced
all json changes were related to a bunch of issues in tests with a filtering in where clause

sqlalchemy dependencies introduce lots of changes, which do not allow to prepare tiny diffs. god bless flask and all its dependencies was not required to be upgraded together with sqlalchemy deps

AndrewChubatiuk · 2023-12-22T10:21:54Z

@masayuki038 could you please trigger ci from the latest commit, I've fixed lint there

masayuki038 · 2023-12-22T12:24:47Z

It looks ci is running now...

build for a latest commit was not triggered

For some reason, CI stopped working, so I will cancel the review.

masayuki038 · 2023-12-23T02:07:05Z

@AndrewChubatiuk I manually re-run Github Action, but I may not have been able to fetch the latest code. I tried deleting my review, but the status did not change.

Could you try pushing something? Or could you please close this and create another PR?

AndrewChubatiuk · 2023-12-23T08:03:07Z

@masayuki038 please approve this pipeline

I understand correctly that we are still abandoning simplejson ?

konnectr · 2023-12-24T04:47:43Z

I will try to test the operation in manual mode in the near future. It is unlikely that our auto-tests cover all possible problems

masayuki038 · 2023-12-24T07:39:13Z

@konnectr Thanks! I will start to review this next week as well.

@AndrewChubatiuk
Sorry for the delay. I have finished reviewing this for now. Please check the comments.

Regarding the following points, I am not pointing out every line. If you will fix it, fix it all.

Please do not include updates that are not directly related to upgrading to SQLAlchemy 1.4 in this PR
- However, I agree with your updates almost. Please separate to another PR
In some places, count() has been changed to len(...). Please use count()

thank you.

-            updated_query_ids = models.Query.update_latest_result(query_result)


I missed this update... Could you let me know why you removed this line?

QueryResult and Query have relationship, there's no need to run multiple queries to store both separately (especially, when Query object already exists), doing everything in store_result function

It looks like that Query is updated in update_latest_result.

redash/redash/models/__init__.py

Line 741 in b7f22b1

db.session.add(q)

Can we skip this update?

update_latest_result method was removed

Query was updated in the method(as below).

redash/redash/models/__init__.py

Lines 737 to 741 in bd17662

for q in queries:

q.latest_query_data = query_result

# don't auto-update the updated_at timestamp

q.skip_updated_at = True

db.session.add(q)

Is there an alternative to this? Or have you decided that this process is not necessary? If you decide that it is unnecessary, please let us know the reason.

It seems to me that without this update, Redash's behavior will be affected. Isn't Query.lastest_query_data and some attributes no longer updated?

i do not see contradiction, from what you've posted.

Referenced by: TABLE "queries" CONSTRAINT "queries_latest_query_data_id_fkey" FOREIGN KEY (latest_query_data_id) REFERENCES query_results(id)

so 1 QueryResult to many Queries

I don't think that having Foreign Key constraints has anything to do with multiplicity.

I thought 1 Query to many QueryResults (like this).

Is it not correct?

Query has latest_query_data_id attribute, which references private key in QueryResult table, which means, that multiple Query object can set the same latest_query_data_id, which means that 1 QueryResult will be referred by multiple Queries - 1 QueryResults many queries

hey @masayuki038
sorry for time you've spend in a review process, but closing this PR as not going to work on redash any further

which means, that multiple Query object can set the same latest_query_data_id,

This is the case if different Queries have the same query_hash. However, it is caused by hash value collisions, right? I don't think we should discuss it in this context.

1 Query - many QueryResults

Yes. Therefore, I think we should name query instead of queries in QueryResult. That is my point.

@masayuki038 i update only things, which are impacted by pr comments changes

masayuki038 · 2024-05-02T12:32:42Z

@AndrewChubatiuk OK. But, I don't think we need to update "assert_called_once_with("requests.redash_ping.get", ANY)" to "assert_called" like the above thread by upgrading to SQLAlchemy 2.0... Why did you update it yesterday?
