[SIO-2521] Submission confirmation e-mail should contain the SIO login

Wed, 7 Dec 2022 22:41:13 +0100

The current e-mail sent by SIO looks as follows. Please add user login. I got a complaint where a contestant mixed up their ids and there was no way of checking this natural information in the e-mail.

[SIO-2520] Error 403 when clicking on a question's author in SIO2

Tue, 1 Nov 2022 21:20:36 +0100

I am a contest admin but not SIO2 admin in contest https://sio2.mimuw.edu.pl/c/oi30-1/. For each question asked by the contestants, I have 3 clickable links: author, date and question topic. The first one (e.g. https://sio2.mimuw.edu.pl/c/oi30-1/u/74551) produces error 403 for me. I presume that this is to show me that I don't have permissions to view the user data (right?), but my user feeling is unpleasant.

[SIO-2519] Failing nightly tests on GitHub Actions

Link https://github.com/sio2project/task-package-examples/blob/master/tutorial/kwa/doc/kwazad.pdf gives error 404 on https://github.com/sio2project/oioioi/wiki/%5BPL%5D-1.-Podstawowa-paczka

[SIO-2516] Link to problem package structure should be accessible via Szkopul

Thu, 29 Sep 2022 11:53:18 +0200

This guy: https://github.com/sio2project/oioioi/wiki should be linked somewhere. Perhaps here: https://szkopul.edu.pl/c/wprawki-wp-2022/admin/contests/probleminstance/

[SIO-2515] Problem package without tests in in/ fails

Thu, 29 Sep 2022 11:52:07 +0200

A task without tests generated in in/ does not upload to Szkopul. It can be the case that all tests are automjatically generated, though. So it should be uploaded afaik.

[SIO-2514] SameSite atribute in language preference cookie

Mon, 6 Jun 2022 13:10:40 +0200

Firefox warns:

Cookie “lang” will be soon rejected because it has the “SameSite” attribute set to “None” or an invalid value, without the “secure” attribute. To know more about the “SameSite“ attribute, read https://developer.mozilla.org/docs/Web/HTTP/Headers/Set-Cookie/SameSite

[SIO-2513] Export reports for all submissions

Mon, 30 May 2022 17:47:11 +0200

For resolver purposes the following data are needed in json format for every submission(report):
- time of submission
- submitter data (probably login or/and id)
- task id
- submission score
- id of first test not marked as "OK"
( optionally - list of tests and verdicts )

[SIO-2512] Allow configuring who can rejudge

Mon, 23 May 2022 12:56:49 +0200

Currently teachers are able to make mass rejudges (via selecting submissions in submissions tab). In case of small rejudges (<100submissions) this is not a problem. When bigger rejudges occur, filetracker2 dies due to big number of requests from Workers.

In perfect scenario we would replace the inefficient storage backend, but it would require a bit of work. Current workaround is to decrease CONCURENCY in settings.py, but it might be a nice feature to be able to control access to this (mass rejudge) feature.

One way I was thinking to implement it is adding a predicate can_mass_rejudge w ContestController getting a request and rejudge order. One can override its behavior per ContestController basis.

[SIO-2511] Maybe use default django 404 page

Mon, 9 May 2022 12:49:43 +0200

We are still using custom 404 page (see `handler404`), due to Django security issues, but it seems, that they, are not longer present in new versions.

Check if 404 page provided by Django has no known security issue, and see how it looks. If there are no reasons not to, change 404 page to be the one provided by Django.

[SIO-2507] JavaScript error when visiting web-page

When opening oioioi the "Cannot read property 'addEventListener' of null" appears in console. Due to this, Cypress tests cannot be properly run.

[SIO-2506] Improve PreferenceFactory

Mon, 25 Apr 2022 12:47:49 +0200

Following changes added `PreferenceFactory` class that is used to generate preference forms, currently used to generate edit profile view form:
https://jira.sio2project.mimuw.edu.pl/browse/SIO-1624
https://gerrit.sio2project.mimuw.edu.pl/#/c/2291/

Currently only place where `add_field` method is used is inside:
1. base/forms.py > _maybe_add_field
2. base/views.py > adjust_preferences_factory_fields
3. tests

Two improvements have to be made:
1. `_maybe_add_field` function takes label strings from settings, where they are translated. Functionality should be added to automatically translate labels in `PreferenceFactory` and move translation logic out of settings. It should be considered if label names shouldn't be moved from settings entirely.
Alternatively field labes can be made into positional parameter, and translation will occur in caller.

2. With addition of `UserPreferences` model `PreferenceFactory` needs functionality to automatically add fields from `UserPreferences`, similarly to how forms can be automatically generated from models.
It is currently made manually inside `adjust_preferences_factory_fields` which can badly impact future refactor/updates.

[SIO-2502] Github actions - translations

Fri, 27 May 2022 14:26:23 +0200

Migrate hudson actions for managing translations to Github:

* https://hudson.sio2project.mimuw.edu.pl/job/oioioi-translations-download/
* https://hudson.sio2project.mimuw.edu.pl/job/oioioi-translations-upload/

Review other jobs from Hudson, in particular verify how hard is to migrate:

[SIO-2501] Auto-created primary key used when not defining a primary key type warning

Thu, 14 Apr 2022 10:02:06 +0200

Because of the change in Django 3.2, when defining a model, if no field in a model is defined with primary_key=True an implicit primary key is added. The type of this implicit primary key can now be controlled via the DEFAULT_AUTO_FIELD setting and AppConfig.default_auto_field attribute. No more needing to override primary keys in all models.

To avoid unwanted migrations in the future, configure it on a per-app basis by adding default_auto_field = 'django.db.models.AutoField' in all AppConfig classes.

[SIO-2496] add missing migrations

Mon, 28 Mar 2022 21:10:55 +0200

clean installation (i.e. from docker) has some pending migrations
(1 in django-rest-framework, 1 in django-simple-captcha, 1 in oioioi/problems).

solution:
- upgrade django-rest-framework
- upgrade django-simple-captcha
- add missing migration to oioioi/problems

[SIO-2495] Dodanie preferencji użytkownika

Wed, 13 Apr 2022 16:15:53 +0200

Aktualnie nie istnieje możliwość prostego dodawania ustawień/preferencji użytkownika. Należy więc dodać model preferencji wraz form-ą ustawiającą je lub zaimplementować je w inny sposób.
Ostatecznie dodanie nowej preferencji użytkownika powinno sprowadzać się do kilku linii kodu, podobnie jak przy ustawieniach contest-u.

[SIO-2494] upgrade pytest

Mon, 25 Apr 2022 12:39:56 +0200

Currently code is using pytest version 4.6.11 (released on 2020-06-04).

Current version is pytest 7.1.2 (released on 2022-04-23).

It seems that there are no reasons why we should use 4.x pytest version,
so we should use latest version of pytest in setup.py.

Some changes in tests API might be required:
https://docs.pytest.org/en/latest/backwards-compatibility.html

[SIO-2493] Solutions are not scored after clean SIO initialization

Mon, 11 Apr 2022 15:35:57 +0200

After clean initialization of SIO solutions are not scored due to the lack of a few directories in 'web' container.

They can be easily crated using
```
mkdir -p media/links/submissions
mkdir -p media/links/problems
```
using container's bash (at /sio2/deployment), but this process looks like it could be solved during Docker initialization (in Dockerfile).

Update: It seems that the problem cannot be solved that easily. Creating the directories does not change anything. The first submission is never successful, but every other is.

This is the log generated at the page.

[SIO-2492] Translated strings which end with a space.

Sat, 26 Mar 2022 22:56:21 +0100

Some of strings translated in OIOIOI end with a space, which is very hard to notice in Transifex and can lead to errors such as this in a screenshot.

[SIO-2491] No avatar for admin created users

Tue, 4 Oct 2022 11:24:05 +0200

When logging in with a user account created via administrator panel there is no avatar photo in upper right corner.

[SIO-2490] Page at /api/docs/ generates response code 500

Wed, 6 Apr 2022 14:59:59 +0200

Visiting the page /api/docs/ at local oioioi or szkopul.pl results in response code 500 or `'AutoSchema' object has no attribute 'get_link'`.

[SIO-2489] End-to-end testing with Cypress

Sun, 14 Aug 2022 14:57:46 +0200

Selenium tests are not working.
I propose new solution using Cypress (https://www.cypress.io).
Advantages:
- useful gui
- screenshot (or video) on test failure
- type safe tests (written in Typescript)
- testing on multiple browsers

I created PoC test suite: https://sinol3.dasie.mimuw.edu.pl/incvis/oioioi/merge_requests/1

See patch for more details.

[SIO-2488] Make tests work with apostrophe encoded as both ''' and '''.

Mon, 28 Mar 2022 10:50:26 +0200

Currently some of tests checking whether response contains a phrase with an apostrophe assume that is encoded by ''' (or before upgrade to Django 3.0 - '''). It would be better to improve these tests so that they work without making such assumption.

[SIO-2487] cleanup filterwarnings setting in pytest.ini

Thu, 10 Mar 2022 08:38:18 +0100

Currently filterwarnings ignores almost all depracationwarnings from oioioi code. This is inconvenient for testing library upgrades.

Proposed changes:
- show all warnings from oioioi during pytest
- fail pytest on selected warnings
- fix most important warnings and create Jira tickets for more time consuming

[SIO-2486] Merge hotfixes from szkopul to master branch of oioioi

Sun, 5 Jun 2022 12:01:19 +0200

Repository
ssh://gerrit.sio2project.mimuw.edu.pl:29418/szkopul
contains several hotfixes and changes dedicated to szkopul.edu.pl.
On every deployment changes from main repository are rebased on top of szkopuł repo (see https://hudson.sio2project.mimuw.edu.pl/job/szkopul-rebase/).

This procedure is inconvenient (i.e. hotfixes are not tested, sometimes there are conflicts during rebasing).
We should try to move as many hotfixes as possible to main code and/or move some functionality controlled by system settings.

Results of `git diff github/master origin/master -- ':!*/npm-shrinkwrap.json'` attached to a ticket.

[SIO-2485] Adding SmartJudge -- possibility of judging only tests that affect score

Wed, 9 Mar 2022 13:19:26 +0100

SmartJudge is a tool implemented by Karol Farbis on SIO2 staszic (https://github.com/InformatykaNaStart/staszic-sio2). It allows to set a mode where only essential tests are judged, so when one of the tests is not OK, all other tests in given package are ignored.

[SIO-2484] broken tests for django 2.2.26

Wed, 23 Mar 2022 13:29:18 +0100

Due to changes in Django 2.2.26 some tests fail.

Cause:
- changes for dictsort usage in templates: https://docs.djangoproject.com/en/4.0/releases/2.2.26/#cve-2021-45116-potential-information-disclosure-in-dictsort-template-filter

How to reproduce:
- pip3 install -U django==2.2.26
- docker-compose -f docker-compose-dev.yml -f extra/docker/docker-compose-dev-noserver.yml exec "web" ../oioioi/test3.sh -v oioioi/problems/tests/test_task_archive.py

affected template:

+++ b/oioioi/problems/templates/problems/task-archive-problemgroup.html
{% for value, subdict in problems.subnodes.items|dictsort:"0.order" %}

affected view:

task_archive_tag_view

code
```
problems.subnodes.items|dictsort:"0.order"
```
sorts tuples (subnodes.items()) by value of order attribute of first element of tuple (key)

[SIO-2483] Mitigate possibility of input data tasks leaks

Wed, 16 Mar 2022 20:35:18 +0100

Mitategate possibility of leaking input data for tasks with full-feedback.
During Algorithms & Data structure exams it happened few times that students leaked input data for tests using printing tests.

Workaround (used during one exam): custom checker that limits verbosity of wrong answer result (see attached sorchk.cpp)

Dwie możliwe (i łatwe do wprowadzenia) opcje:
  1. Uczestnik wcale nie widzi komentarzy do testów z wynikiem WA.
  2. Uczestnik widzi komentarze do testów z wynikiem WA, ale ucięte bardziej niż obecnie (np. do 80 znaków).
Poza tym pozostają dwa pytania:
  - Czy powinno to być ustawienie dotyczące contestu, czy rundy? Jako ustawienie pojedynczego zadania raczej nie ma sensu (główne potencjalne zastosowanie to kolokwia, egzaminy, sprawdziany, gdzie ukrywanie komentarzy dotyczy wszystkich zadań).
  - Czy ukrywanie powinno dotyczyć tylko czasu trwania rundy (jeżeli byłoby to ustawienie rundy), czy powinno być aktywne aż do wyłączenia przez administratora contestu?

[SIO-2482] Add option for contest configuration to ignore invalid submissions

Mon, 28 Feb 2022 09:43:33 +0100

Add option for contest configuration (i.e. Olimpiada Informatyczna), such that:

As a contestant I would like to avoid situation when submitting wrong file cancels my score for already solved task (i.e. if by mistake I submit solution for task A as a solution for task B).

Such situation happens rarely (but it happens) during OI contests (for example it happened once this year in Feb 2022).

Possible solutions:
- ignore in ranking solutions that does not pass example tests
- use in the ranking last solution that pass example tests (tests that are included in the task description)
- [SPECIAL CASE] if for some task there are no solutions that pass example tests then use in ranking last submitted solution

[SIO-2481] Store author's information about packages

Tue, 8 Feb 2022 22:29:14 +0100

In main (no. 1) it was possible to specify problem's author. We should add this metadata to the package's config and parse it in oioioi.

[SIO-2480] Translation of default iomode in sinol.cls file is not working

Tue, 8 Feb 2022 14:05:25 +0100

In /oioioi/sinolpack/files there is a sinol.cls file.
When used in task statements, it has a default iomode (\iomode{files}).
It does not update translations of example input/output texts, making them always polish.

PS: Moving the line to the bottom might fix the issue.
PSS: Should files really be the default iomode?
PSSS: And should we really use 8 years old sinol.cls file? There are surely newer versions around in use.

[SIO-2479] Fix problemset URLs

Wed, 26 Jan 2022 14:14:38 +0100

When somebody tries to go to problemset while being in some contest, the URL "remembers" the contest (the suffix is /c/contest_name/problemset) .

Because of that users are not able to submit to any problem.

Steps to reproduce:
1. Choose any contest from the main page.
2. Choose problemset from dropdown menu in the navbar.

[SIO-2478] Add link to the solution of each problem in problems tab

Mon, 31 Jan 2022 09:31:26 +0100

When somebody wants to look for a solution of some problem they submitted a long time ago, sometimes it can be hard to find it in a long list of submissions.

I suggest adding a hyperlink to a last submission of a score visible in a 'problems' tab. This will improve users experience as well as save a lot of time.

[SIO-2477] simplify deployment

Mon, 28 Feb 2022 09:56:58 +0100

Currently deployment requires:
- manual patching of master branch with custom list of commits
- using external scripts
- is not documented well

Goals:
- all patches are included in master branch (and possibly turned on/off by settings)
- scripts are includes in the repo
- there exists some documentation for the process

[SIO-2476] migrate from python 3.6 to 3.7 or 3.8

Mon, 28 Feb 2022 09:31:38 +0100

Support for python 3.6 ended on 23 Dec 2021.

[SIO-2475] drop support for python 2.7

Fri, 22 Apr 2022 17:45:30 +0200

python 2.7 support ended on 01 Jan 2020

[SIO-2474] Fix night builds

Mon, 28 Feb 2022 09:33:28 +0100

Night tests on Hudson are failing since May 2021.
This is due to version conflict for Python 2 installation.

Goals:
- remove support for python 2 in nighthly tests and move to python 3
- make sure that tests are passing and they take less than 1.5hr

[SIO-2473] Invalid INDEX format in export submission

Wed, 23 Mar 2022 09:03:57 +0100

After "Export submission" the format of INDEX file is invalid.
Most columns are exported with binary string tag (see anonymized screenshot).
UTF characters are exported in hex format.

Expected behaviour:
INDEX file that can be loaded to Excel or pandas.read_csv

[SIO-2472] c++17 support in sinol makefiles

Sun, 2 Jan 2022 22:51:07 +0100

Currently we override makefiles in sinol packs, which force c++11. Jury want's c++17, which is fairly available on modern machines.

[SIO-2471] Missing edit test options

Mon, 31 Jan 2022 09:32:06 +0100

Recently we received complaint about missing options in PI edit UI. Please see the e-mail attached.

[SIO-2470] Race condition in ranking creation

Mon, 11 Apr 2022 09:01:15 +0200

Sometimes, the same user is enlisted twice in the ranking. See attached screenshot.

[SIO-2469] List of rounds for specific contest

Mon, 12 Dec 2022 08:42:10 +0100

Query https://sio2.mimuw.edu.pl/c/pa-2021-1/status/ returns information about one round (current or future) only. Can you add a list of rounds for a specific contest with times information?

I want to create automatic export contests and rounds to clist.by.

[SIO-2468] Bycie anonimowym nie robi cię anonimowym

Thu, 17 Mar 2022 19:19:45 +0100

Obecnie istnieje możliwość "anonimowego" uczestnictwa w konkursie. Polega ona na zastąpieniu imienia i nazwiska uczestnika jego loginem w rankingu.

Nie jest to rzeczywista anonimowość - login może zawierać fragmenty nazwiska, być znany dla kolegów itd.

Ponadto, opcja ta jest niedostępna w większości konkursów.

Możliwym rozwiązaniem jest używanie ustalonego ciągu znaków ("???", "anonimowy" itd) w miejsce loginu.
(Można by też takich uczestników wcale nie pokazywać w publicznym rankingu, przy czym wydaje się to rozwiązaniem bardzo niekorzystnym.)

Kwestie do rostrzygnięcia:
1. Czy nowa wersja powinna zastąpić dotychczasową, czy istnieć równolegle do niej (do wyboru dla administratora pomiędzy brakiem anonimowości / loginem / "???")
2. Jak powinno wyglądać zarządzanie tym ustawieniem - np. ustalone w typie konkursu (tak jak obecnie) lub możliwe do modyfikacji w ustawieniach konkursu (ewentualnie wartości domyślne dla danego serwera)

Dla zachowania zgodności ze stanem obecnym sensowne wydaje się wprowadzenie tej zmiany jako nowej opcji per konkurs, która nadpisywałaby dotychczasowe zachowanie.

[SIO-2467] Bulk move problems between contests

Sun, 28 Nov 2021 15:13:48 +0100

Currently it is possible to move problems on one by one basis. New feature will allow to select and move problems from one contest to another all at once.

This will speed up contest creation when some of the problems are reused.

[SIO-2466] Participation in contest without being visible in Ranking

Sun, 28 Nov 2021 15:04:17 +0100

We heard that some participants are "afraid" to participate because their result will be visible on the public Ranking list.

This feature will allow less confident participants to take part in contest without exposing their results to their colleagues.

[SIO-2465] Limiting visibility of Ranking list

Sun, 28 Nov 2021 15:07:24 +0100

Setting visibility of Ranking list for particular contest, depending on admin's choice.

Visibility modes:
- hidden
- visible to teacher only
- visible

[SIO-2464] In some browsers "No, go back" button deletes account at /delete_account.

Wed, 8 Dec 2021 23:30:59 +0100

On page "/delete_account/" the "No, go back" button also removes account.
This problem was diagnosed on chrome based browsers (Google Chrome, new Microsoft Edge), but not on Firefox.

HTML standard says button with no type is submit. Firefox documentation says button with no type is submit if no submit button is present in the form and button otherwise. It worked in Firefox, but only due to incompatibility with the standard.

Therefore they should had been given type different from "submit".

[SIO-2463] Incomplete support for quiz problems

Fri, 28 Jan 2022 11:40:38 +0100

* "Add a quiz", "Quiz name" are not translated into Polish.
* It is possible to enable reveals for a quiz problem, but then trying to open submission page results in RelatedObjectDoesNotExist exception.

[SIO-2462] Upgrade django do wersji 3.2

Wed, 13 Apr 2022 15:52:42 +0200

Wsparcie do 2.2 kończy się 2022-04-01.
Obecna wersja LTS to 3.2.

Release notes 3.2:
- https://docs.djangoproject.com/en/3.2/releases/3.2/

Wersja minimalna: to rozpoznanie niekomatybilności i dokładne oszacowanie złożoności migracji

Przydatne linki:
- https://theorangeone.net/posts/django-32/

Dodatkowy problem, który trzeba będzie rozwiązać to upgrade wersji Pythona na maszynie ripper.
Obecnie do testów w Hudson używany jest Python 3.5 a Django 3.2 wymaga Pythona 3.6 lub lepszego.
(być może da się wykorzystać ~/.pyenv/versions/3.7.10/bin/python)

[SIO-2461] Why is the space a dissallowed character in profile's name field

Thu, 25 Nov 2021 23:25:25 +0100

Currently we inform users with invalid characters in their personal details that they change it, but we have users with two-words names (mostly Asians). We should consider redefining allowed symbols in names.
One should investigate where currently allowed symbols came from and update them is possible.

[SIO-2460] Require password in account deletion form

Wed, 8 Dec 2021 23:31:05 +0100

We get regularly complaints that sometimes students did not logged out of school computer and someone deleted their account as a bad joke.
What is worse is trying to recover the deleted accounts.

[SIO-2459] Resolve "Stop using CDNs" Github issue

Mon, 10 Jan 2022 18:20:16 +0100

In sio2 we use local copy of mathjax. We should document how to set mathjax source for the browsers and close the issue (https://github.com/sio2project/oioioi/issues/44).

[SIO-2458] Unhelpful compiller configuration error messages

Wed, 24 Nov 2021 13:55:09 +0100

Currently we enforce some structure on *_COMPILERS in settings.py, but when structure is invalid we raise ImproperlyConfigured error without telling what is invalid, which makes changing the config more challenging.

[SIO-2457] Bardziej intuicyjny zielony pasek

Thu, 23 Dec 2021 20:20:28 +0100

Pasek, który wskazuje ile czasu zostało do końca zadania może wprowadzać w błąd i sugerować, że coś się nie załadowało.
Możliwa poprawka to np dodanie możliwości najechania na pasek i wyświetlenia co znaczy.

[SIO-2456] Zaznaczanie bieżącej pozycji na rankingu

Tue, 25 Jan 2022 21:15:17 +0100

Na stronie rankingu, zalogowany użytkownik mógłby być od razu zaznaczony (teraz trzeba kliknąć Find my place), kliknięcie przycisku mogłoby jedynie przenosić widok do miejsca w rankingu bieżącego użytkownika.

[SIO-2455] Podgląd wyników zgłoszenia bez odświeżania strony

Mon, 9 May 2022 23:05:58 +0200

Obsługa dynamicznych stron WWW dla strony moje zgłoszenia. Odświeżanie w tle listy i statusów submittów.

Coś podobnego jest serwerze Staszicowym.

Być może to jest za duże:
- można ograniczyć do tylko wyświetlania informacji "są nowe dane odśwież stronę"
- inne temat to synchronizacja zegara (czas do końca konkursu) - bez odświeżania strony potrafi się rozjechać o kilka minut

[SIO-2454] Poprawki do tłumaczeń

Wed, 12 Jan 2022 14:44:24 +0100

* na stronie głównej zalogowanego użytkownika, w angielskiej wersji:
"Any planned downtime outside of these ours will be separately announced here." ours -> hours
* w angielskiej wersji po wybraniu "edit profile" informacja o zgodzie na przetwarzanie danych osobowych jest po polsku -> powinna być wyświetlana angielska wersja zgody

[SIO-2453] Dark mode

Wed, 17 Nov 2021 15:10:32 +0100

Dodanie możliwości zmiany motywu kolorystycznego na ciemniejszy/mniej męczący wzrok.

Potrzebny:
- projekt UI do zmiany trybu dzienny/nocny
- jak mają wyglądać nowe kolory
- ustalić kto musi zaakceptować nowe kolory (poza TAG)
- uzyskać akceptację nowej kolorystyki

[SIO-2452] Wbudowany edytor kodu

Wed, 18 May 2022 16:25:10 +0200

Dodanie edytoru kodu z podświetlaniem składni do formularza Submit.
np. https://codemirror.net/

- research jakie edytory są dostępne (jakie mają możliwości vs wymagania vs ograniczenia licencyjne)
https://docs.google.com/document/d/1oHSLtrvRf5zkoERskaPn1en1mNUE16Vogu_Yho8bBpY/edit?usp=sharing

- czy użytkownik może wlączyć/wyłączyć taki edytor
- co robić na stronie jeśli edytor nie działa poprawnie

[SIO-2451] Uporządkowanie ustawień sklonowanych zadań

Wed, 27 Oct 2021 18:18:37 +0200

- cześć ustawień jest lokalnie per konkurs
- część globalnie na cały system
- usuwanie załączników

[SIO-2450] Prirytetowanie zgłoszeń do sprawdzania

Wed, 27 Oct 2021 18:17:19 +0200

możliwość szybszego sprawdzenia wybranych zgłoszeń

[SIO-2449] Symulator konkurs treningu

Wed, 17 Nov 2021 15:01:39 +0100

- przycisk replay dla istniejącego konkursu (np. wirtualny II etap czy egzamin)
- zwłaszcza istotne dla konkursów bez full-feedback
- codeforces ma coś podobnego

[SIO-2448] Webowy manager zadań

Wed, 27 Oct 2021 18:14:36 +0200

- żeby można było łatwo wyszukiwać zadania
- żeby można było łatow kopiować pomiędzy konkursami
- żeby można było dodawać dokumentację do zadań
- żeby można było wersjonować paczki

[SIO-2447] Disqualification on Quiz Submission results in 500 for the user

Sun, 9 Jan 2022 22:14:22 +0100

We should allow for disqualifications based on any submission type or at least check for valid submission types when adding disqualification object.

[SIO-2446] Duplicate contest problems

Sat, 25 Sep 2021 10:03:29 +0200

Say you conduct lessons in 2 groups and you want to have the same problems in both contests, but manually copying all problems is annoying. It would be nice to have a button "duplicate contest"

[SIO-2445] Dupli(Multi-)plicates of the same participants in the ranking

Sun, 19 Sep 2021 00:33:27 +0200

Participants are displayed multiple times despite using one account:
1 Jan Ni 100 100 200
1 Jan Ni 100 100 200
1 Jan Ni 100. 100 200 https://szkopul.edu.pl/c/zadankasrednie/ranking/ for example in this contest, but I've seen it multiple times.

[SIO-2444] Compiller override form bricks on error

Tue, 7 Sep 2021 10:03:29 +0200

How to reproduce:
1. Create a new contest
2. Create compiller override

[SIO-2443] Output of checker is inserted to the database as is

[SIO-2437] NOTIFICATIONS_SERVER_ENABLED setting is confusing

Sat, 15 May 2021 11:43:33 +0200

NOTIFICATIONS_SERVER_ENABLED only tells supervisord whether to start notification-server. However, at first glance, it is not clear what does NOTIFICATIONS_SERVER_ENABLED means:
- Will it start notification server?
- Will oioioi connect to provided server details but not spawn a notification server?
- Will oioioi not connect to any notification server?

[SIO-2436] Add autoreveal for problems with as many reveals as submissions

Mon, 31 Jan 2022 22:34:58 +0100

Currently if organisers want to show users their scores without reports reveal configs are used. However users must click reveal score every time they submit a solution.

If no. of submissions <= no. of reveals we should reveal scores automatically.

Proposition of implementation:

Instead of checking if no. of submissions <= no. of reveals, allow to leave no. of reveals field empty and add explaining help text to it. Then if no. of reveals is None, user can see the score of their every submission, unless it is submitted during the last [disable_time] minutes of the round. In "Score revealing" section on submission page:
- If user cannot see the score, there is a message explaining why (same as this shown now instead of reveal button) - submission has status "CE", it is not scored yet or it was submitted during period, when reveals are disabled.
- If user can see the score, there is the score and additional information that scores of all submissions in the task are visible automatically, unless submitted during the last [disable_time] minutes of the round.

The other way could be to completely remove "Score revealing" section from submission page when no. of reveals is empty. But then, where would we show the information about disabling reveals in last [disable_time] minutes of the contest, if it is enabled? Also, waiting long for a submission to be scored can make user think that the reveals are disabled if there is no "Score revealing" section.

If no. of reveals if specified, system behaviour should not change.

Tue, 30 Mar 2021 00:37:42 +0200

Create contest controller with specified languages -- e.g. add

Mon, 22 Mar 2021 17:16:48 +0100

[SIO-2405] Prioritize certain kinds of statuses when aggregating ACM-style test results

Mon, 7 Jun 2021 01:03:57 +0200

In ACM-style contests, the user-visible result for a submit is "AC" when all tests pass, and some type of error status when one or more tests fail.

Currently, if multiple tests fail with different statuses, the "first" failure is shown.
Moreover, "first" is defined according to some internal order, different from the order visible in UI.

It'd be preferable if the status to display was chosen based on type of failure, and not order of tests.
For example, RE could take precedence over WA, then MLE, then TLE, etc.

[SIO-2398] Allow opening registration at a later date on contests with public registration

Mon, 28 Feb 2022 20:46:27 +0100

Contests such as PA and OI have a public registration form that any registered user can fill in to become a participant.

They can do this as soon as the contest is created, which leaves very little time for contest admins to configure the contest properly before someone registers.

There should be a registration start date, or an "enable registration" checbox, in the contest settings (including contest creation form), which contest admins can use to keep the registration closed until they're ready.

[SIO-2397] Use automatic source code formating on the project

Fri, 19 Nov 2021 17:50:49 +0100

For a year or two, the pylint hooks on gerrit weren't working, so a large portion of the code may not be following our code style.

We could use an automated code formatting tool such as "black" or "darker" to reformat that code, and possibly keep code automatically formatted in the future.

However, our project has a few peculiar conventions, such as the distinction between single and double quotes. It'd be better if we could keep them, so code formatting tools may need some special configuration for this.

Also, if we were to do code formatting when unrelated changes are being made, care must be taken to keep the diffs readable.

[SIO-2396] API: Allow finding a problem by contest_id and short_name

Relates — Thu, 24 Jun 2021 11:45:09 +0200

Contest id and problem short name already uniquely identify a problem instance, so they could be used to find it, and the problem.

It would be nice to have an API that allows obtaining problem_id (and possibly problem_instance_id) by providing contest id and problem short name.
The problem_id would be very useful for reuploading a package from a CI, which does not necessarily know it beforehend, but does have access the contest id and short name in the package source.

[SIO-2395] API: Allow contest/problem admins to query package upload status

It'd be better if everyone who can upload a problem using the API could also query the status of the package they uploaded.

[SIO-2392] Exportszu times out

Duplicate — Wed, 16 Dec 2020 13:01:42 +0100

In large contests, generating an archive of every contestant's submissions takes a long time. Because the "export submissions" functionality does this synchronously, it causes a "504 gateway time-out" error before the archive is finished and ready for download.

One way to fix this would be to generate the arachive asynchronously, with a similar UX to generating user outs - you click once to generate the archive, and after a while, when the archive is done, you refresh the page and get a link to download the archive. In this case, care must be taken to keep track of when the archive was generated, as submissions created after that moment won't be included, and the user should be warned about this.

Another option would be to use a streaming response, so that the archive is being sent to the user as it's being generated. This could make the download slower than necessary, but at least the start of the response would arrive sooner, hopefully avoiding timeouts.

Yet another possibility is that this operation is slow for no good reason and could be made faster.

Thu, 24 Jun 2021 12:12:17 +0200

The version constraints in oioioi's setup.py are rather chaotic.

Some of them weren't updated when we updated Django, which means we're using unnecessarily old dependencies.
Other have hardcoded versions from some point in the past.
Other don't have less-than constraint, allowing newer, incompatible versions of some package to be installed.

We should go through each of them, find out the maximal range of versions that works correctly with our version of Django and Python, and set the constraints to that range.

[SIO-2375] Remove deprecated compiler names.

Thu, 24 Jun 2021 12:13:27 +0200

After 01.01.2021 deprecated compiler names should be removed.

Their list can be found in the setup.py of the sioworkers.
They should be removed not only from that file, but also all throughout sioworkers, including the rst documentation.
One small problem is that sio-compile standalone script uses deprecated 'default-' compiler names (in the function sio.compilers.job:main). It therefore needs some other, preferably local, constants to select default compilers for languages.
In every other place, to the best of my knowledge, the deprecated compiler names can be removed safely.

The deprecated compiler names are also present in OIOIOI (I grepped them in two places, I may have missed some). As far as I know they exist in code paths that are never taken, so there they can also be safely removed.

Affected changes:

Problem:
The database query is too heavy.

TODO:
Optimize the database query.

Description:

As for now user contests will be visible for all registered users.
This is something we don't want. (The user contests should be visible only to people who visited them before)

The changes above aim to resolve this issue. But there is a side effect.
In the first change there is a query that is not optimized by django:
"return Q(contestview__user=request.user)"

This results in a very heavy query that needs to be improved before it can be submitted to master.

[SIO-2359] Clicking the problem name in Submission View could lead to the problem site

Relates — Tue, 26 May 2020 16:20:36 +0200

From my personal experience, usually when you work on a problem and find out that your solution doesn't work, your first reaction is to want to revisit the problem statement.

It would be only natural to achieve so by clicking the problem name in the submission view. It is unclickable for regular users; however, admins can use it to quickly access the problem (instance?) admin view. Replacing this behaviour with a non-user-dependent problem link might be worth considering.

[SIO-2356] Make deployment easier

Tue, 23 Jun 2020 17:21:20 +0200

Create an easy way to deploy OIOIOI using the Docker technology as a backend.
Only the most basic settings should be exposed to the operator, all the other ones should be standardized.
Updating should also be noob-friendly, without the need to read diffs from UPGRADING.rst, etc.

In the light of these changes we should also remove Vagrant support.

When a teacher adds a public problem from problemset, they can modify some task settings.
There are however two links, to which the teacher, not owning the problem, has no rights.
These are package link (to download package) and advanced problem settings link.
Error 403 occurs, when entering those links.
It would be worth removing those links from teacher view

[SIO-2351] Cannot add to contest from "add to contest" in problem site

[SIO-2350] API: no problem_id after package_upload

Relates — Wed, 16 Dec 2020 09:23:23 +0100

Names from: https://sio2.mimuw.edu.pl/api/docs/

There is no way to check problem_id after package_upload, within API.
It makes impossible automatic reuploading package inside CI, without checking id by hand.

Because of that, API is much less useful than it could be.

Possible solution:
- package_upload returns package_id,
- package_id allows to check upload status (and problem_id if upload was successful).

Other solutions are also possible:
- Possibility to use package_id instead of problem_id.
- Reserving problem_id at the beginning. On fail, it is still reserved and waiting for package reupload.

[SIO-2349] Super users cannot access user group details

[SIO-2348] Allow owners of problemset problems to decide if tests are public

Thu, 24 Jun 2021 12:14:49 +0200

Many of our problemset tasks have had their tests published.
So it would be convenient to have these tests available @ Szkopul as well.
And maybe we can publish tests which have not been published before, for educational purposes.

Additionally, if a task with published tests is being added by a teacher, it should be clear for her/him that the tests are publicly available.

[SIO-2347] Add tests packages description to config.yml

Sat, 18 Apr 2020 12:05:57 +0200

We often upload packages with example tests and sometimes with all tests (added in TESTS PACKAGES on problem site).

It would be cool to be able to specify these tests packages in config.yml, like this:

tests_packages:
   mar_example_tests:
       description: Testy przykładowe do zadania Marchewka
       tests: [0*]
       publish_date: now

Wildcards and current publish_date are some additional features, not necessary.

[SIO-2346] Changing the name of a category in a forum changes the order of categories as well

Fri, 8 Jan 2021 14:35:51 +0100

When you change the name of some category in a forum, the category is displayed then as the last one. For example, you might have categories: "Something 1", "Something 2", "Something 3". And then when you change "Something 2" to "Something 2 - important update", you are stuck with "Something 1", "Something 3" and "Something 2 - important update". This is of course not ideal.

Quick fix: sort by the creation time.
Better fix: allow to reorder the categories.

[SIO-2345] Adding an announcement just for specific contestant (or contestants?)

Fri, 15 Jan 2021 18:16:19 +0100

Quite often we would like to notify some person or a group of people during the contest. Right now, in "Questions and news" we have just two options: send a public announcement to everyone, or answer someone's questions. Having something in-between, i.e. being able to send an announcement to a specific person, or a group of people would be really handy.

So far, the typical workflow was: ask an admin to su into the contestant account, ask an empty question (as a contestant), and then answer to this question, which is way too complicated and hacky.

[SIO-2344] API: package_upload does not work

Fri, 10 Apr 2020 09:49:21 +0200

```

Error code: 403
Returned JSON: `{"message":"Permission denied."}`

Tested on SIO and Szkopuł by different users with permissions.

PS (to person fixing)
It would be nice, if uploading packed would return problem_id needed by package_reupload, if that doesn't now.

User, reading from left to right, in order to view a question, clicks on the first link - author, and views his list of questions, instead of the question itself. But, pressing both of date links, opens the question.

[SIO-2337] [UI] "Add to contest" button is unnaturally placed in problemset

Relates — Wed, 9 Dec 2020 14:14:40 +0100

In problemset, in problems list, there is an "add to contest" button. When we enter a specific problem, there is no such button anymore. To find it, we need to enter settings, and then, on the left side (in the opposite to other action buttons, which are places to the right), we find a subwindow with the desired action. We could make this button separate, and more reachable.

One of the ideas is in the tabs bar (settings, private key, ect.) add an additional tab-button, aligned to right and visible ad a button (just as in problem list in problemset)

When entering a quiz submittion, there is an option to diff it with previous solutions. However using this options throws an exception.

[SIO-2297] When adding new question to a quiz, rejudging old submissions breaks them

Relates — Tue, 15 Dec 2020 12:54:07 +0100

When a new question is added to a quiz, and then rejudging old submittions to the same quiz, a crash will occur and these submissions will corrupt (making them impossible to view without a crash).
Probably the same will happen, if we remove or significantly change a question (though I didn't test that)

[SIO-2296] System error in quiz not working

Relates — Tue, 3 Mar 2020 16:08:32 +0100

When system error occurs in quiz judging, a crash occurs when trying to open the broken submission.
Instead, a graceful blue "System error" status should appear, with traceback (as it happens, when normal submittion to a problem gets a system error).

Ways to reproduce:
1) break handlers.py for quizes. For example, in function "_match_text_input" delete in if "question", so that unexisting object "quiz" is used. ("if quiz.controller.is_case_ignored():").
After saving the file and relaunching sioworkers, submit a quiz solution and try to view submission.
2) submit a solution to quiz. Then, add a new question to the quiz. Then, rejudge the solution. An error will appear, when trying to view it

[SIO-2294] Reupload package has three possibilities of package selection, while only one is allowed

Relates — Tue, 31 Mar 2020 13:18:06 +0200

When reuploading package, the same UI shows, as when creating a new problem. The UI allows to select an existing problem from problemset, or to create a quiz. When reuploading, both these options are disallowed. Therefor, the tabs should be hidden, showing only one possible option

[SIO-2293] Quiz problem site has unused tabs

Relates — Tue, 3 Mar 2020 16:08:26 +0100

When entering quiz's problem site, there are four tabs, but two of them (files and problem statement) are empty, displaying info that nothing's there. They should be removed

[SIO-2292] Problem actions in admin's problems tab has actions unrelated to quizes

Relates — Wed, 2 Dec 2020 17:48:40 +0100

In admin view, in the problems tab, each problem has some actions.
If a problem is a quiz, it has almost the same set of actions, though half of them is not working.
The actions that should be removed (as they simply do not work) are:
- Model solutions
- Reset tests limits
- Reupload package (does not show always, but can be seen eg. a moment after creation)

Also preferably "Edit problem" should be changed to "Edit quiz", to not misslead the admins about the actions made by that button

[SIO-2290] Set a default file for the 'test run' module

Wed, 13 Nov 2019 17:47:14 +0100

In contests like Polish Olimpiad in Informatics, there is a module for test submission of a problem('test run').
In that module a user is supposed to provide source code of a program and a file with test data. By default no file is selected so to test his/her program the user has to create a file on their local machine and copy to it a default test data from the task description.

Modify the module so that when no file with test data is selected the program will be run on the first initial* test. It shouldn't check the output of the program but rather display it normally as if the initial test was supplied from the user's computer.

* More formally ABC0.in, or ABC0a.in(if multiple initial tests are present). Where 'ABC' is the task's ID.

[SIO-2289] Add easily accessible problem score information in Task Archive

Tue, 26 May 2020 16:20:09 +0200

The old Problemset displayed current scores for all the problems that the browsing user had attempted to solve, in the problem selection view.

This feature is missing in the current Task Archive, which is inconvenient for users wishing both to recognise the problems they've already solved or attempted solving, and the problems they haven't seen before.

Thu, 24 Jun 2021 12:21:50 +0200

Certain settings - eg. testrun configurations or score reveal configurations - depend not just on the problem, but also contest rules, and should be able to differ between contests. Therefore, they should be in probleminstance settings, and not in problem settings.

[SIO-2283] Merge files and tests tabs in the contest view

[SIO-2277] Ranking ingores custom update_user_result_for_{round,contest}

Thu, 24 Jun 2021 12:23:26 +0200

It's possible to override the update_user_result_for_{round,contest} methods in a contest controller, and change the way results for round and contest are computed form a simple sum to something more elaborate. (For example, on OIJ, we need to have max of two different quizzes.)
Those results will be saved in UserResultForRound and UserResultForContest models.

However, the ranking doesn't care. It just takes per-problem scores from UserResultForProblem objects and sums them.

[SIO-2275] Make models' names compatible with python2 and python3

Mon, 22 Mar 2021 17:33:15 +0100

Django models uses internal function of python classes __unicode__ and __str__ to extract 'name' of the given object, e.g. on admin pages.
Because of changes in string representations in Python3 this behavior has to be change (python3 -> unicode, python2 -> str). Fortunatelly django provides very helpful decorator to ensure compatibility with both versions of python.

[SIO-2274] Quizzes improvements for the Junior Olympiad in Informatics

Sun, 31 Oct 2021 18:10:43 +0100

For the Junior Olympiad in Informatics, we would like to use the quizzes module, but we need some more features:
- ability to add pictures and math equations in questions and answers,
- contestants should be able to type their own answer (a single integer or a word)
- add the possibility to differ scoring within one question (for example, there might be an answer worth 1 point, and another answer worth two points)
- we would like to have the following workflow:
-- teacher add a set of questions categorized into several categories
-- contestant can prepare for a quiz, they can generate practice quizzes, the quiz should contain random questions from different categories (for example 10 algorithmic questions and 10 programming questions)
-- finally, they should be able to take a rated quiz, which should be scored.

[SIO-2146] "Send Feedback" dance

Mon, 27 Apr 2020 16:28:43 +0200

The "Send Feedback" form available after pushing "send feedback" button on the right side of szkopul.mimuw.edu.pl moves between two different positions on the screen making it hard to fill it and submit it. I attach a video demonstrating the issue.

Tested Browsers:
- Mozilla Firefox 65.0.2 (64 bits) on Arch Linux - form dancing as in video
- Chromium 72.0.3626.121 (64 bits) on Arch Linux - OK

[SIO-2145] Allow enabling "participants" app without "oi" app

Relates — Mon, 27 Apr 2020 16:28:27 +0200

When you enable participants app without oi app you currently get following exception when migrating
```
django.db.migrations.exceptions.NodeNotFoundError: Migration participants.0004_auto_20160412_1718 dependencies reference nonexistent parent node (u'oi', u'0002_auto_20160412_1720')
```

Hotfix on Szkopul removes that dependency. This dependency was created, becouse "onsiteregistration" was previously part of "oi" app and was moved to "participants" app. Correct order of migrations is important to preserve data in that table if "oi" app is used.

[SIO-2144] "Export submissions" timing out with big archives

Duplicate — Wed, 16 Dec 2020 13:01:42 +0100

When you try to export submissions, it will take a long time to generate an archive, and before OIOIOI starts sending it, it is likely that either a reverse proxy or the browser will time out.

One way to fix this would be to generate the archive asynchronously, and immediately send a response to the user stating that the archive will be available shortly. When the user refreshes the page, and the archive is already ready, the page will show a download link to the archive instead.

Another way could possibly be to start streaming the response while the archive is still being generated. Theoretically, tar should be capable of that. Not sure about Django.

[SIO-2140] It is hard for people not involved in sio2project to report bugs

Mon, 27 Apr 2020 16:28:03 +0200

First of all, nowhere on the JIRA homepage does it say that they need to create an account at accounts.sio2project.mimuw.edu.pl.
There's only login form, and a confusing
"Not a member? To request an account, please contact your JIRA administrators."
text.

Secondly, many fields in the new issue form can be easily filled wrong:
- the "affected version" field is used in a non-standard way, that is confusing to newcomers, and isn't explained anywhere
- in the "component" it's easy to accidentally pick "sio2project website" instead of "OIOIOI" if one doesn't know that "OIOIOI" is actually the name of sio2's web interface.

[SIO-2139] Automatic deployment of contest tasks

Mon, 27 Apr 2020 16:27:44 +0200

As the infrastructure used during the contest preparation phase may be based on git (for example, OI currently is), it would be nice to have automatic deployment.
My idea is to link the master branch in gitlab with SIO2, so that the contest always contains the latest content of the master branch. We want to avoid manual management of packages, as to avoid potential mistakes.

I believe that simplest realization is to create one "shareable" link per task to upload packages. Link works like "reupload package", so it cannot affect other tasks or create a new one.

API should be easy to connect with CI (like GitLab CI).
Access to CI may have more persons than to SIO contest!

Link revoking would be nice.

[SIO-2132] Change submission messages to be more readable

Relates — Thu, 31 Jan 2019 13:15:26 +0100

Every message the user gets back in their submission report is now abreviated, such as INI_OK or CE. Meanings of those are not obvious to new users and thus they should be changed to something more understandable.

[SIO-2131] Fix submission messages to display the full name

Relates — Thu, 31 Jan 2019 13:15:14 +0100

We do stuff like this (in the order of execution):

    # ...
    submission_statuses.register('WA', _("Wrong Answer"))

    class TestReport(models.Model):
        status = EnumField(submission_statuses)
        # ...

    # in different file
    submission_statuses.register('MCE', _("Message Count Exceeded"))

Because of the way EnumField snapshots the registry at construction time,
TestReport.get_status_display will not be aware of MCE's display name.

As a result, Zeus statuses (MCE and MSE) display as "MCE"/"MSE" instead of their full name in the tests table on the submission report page.

Moreover, in the header of submission report page, and on the my submissions page, all statuses (except 'OK', 'ERR' and '?', as those are defined in contests/models.py) show as their acronym (eg. "WA") instead of their full name (i.e. "Wrong Answer")

This may have something to do with ~~SIO-1600~~

[SIO-2124] Incorrect input archive for testrun causes System Error

Mon, 27 Apr 2020 16:29:15 +0200

In a contest with testruns enabled, a participant can send send their own code with their own input to be ran in our evaluation environment.

The specified input file can either be a raw input file, or a zip archive containing a single file with the input data.

If the archive contains multiple files and its extension is not .zip,
the form will not show an error about multiple files,
but workers will detect that there's more than one file, and trigger a SystemError.

The form should validate the archive in the same (or more strict) way than workers do.
Particularly, the method of detecting if something is a zip should be the same in oioioi and workers.
Another way to do it would be to have oioioi explicitely tell the workers if the input is the zip or not. (The workers would still validate if there's only one archive member and unpack it, but wouldn't try to detect if the input is a zip or not.)

[SIO-2123] null-sandbox has incorrect extension

Mon, 27 Apr 2020 16:29:14 +0200

As described in the documentation ( https://sioworkers.readthedocs.io/en/latest/#sandboxes ) null-sandbox.tar.gz has a .tar.gz extension, even though it's an uncompressed tar archive, which should have just .tar extension.

It's possible that this sandbox will fail to unpack because of it. We don't know for sure, because nobody uses this sandbox.

Still this should be fixed, eg. by renaming the sandbox to null-sandbox.tar, or by compressing it with gzip, so that it really is .tar.gz, and adjusting the documentation to reflect the change.

Can we have a more structured task archive, I mean:
- we can have a tree of contests (for example Contests > OI > XXI OI > II stage > First day), then problems can be attached to the corresponding nodes,
- then we can have cool URLs (people complain that the problem URLs are unnecessarily long, MAIN had way better URLs, for instance: main.edu.pl/archive/oi/12/nad/, if I remember correctly),
- then we can have some cool statistics (for example you have solved 95% of all tasks from OI).

Mon, 27 Apr 2020 16:27:50 +0200

2) for already compressed files (.zip, .gz), compressing them once more on the filetracker level makes no sense

Both client and server should be modified to support both compressed and not compressed files.

[SIO-2073] Set environ['required_ram'] for various worker jobs

Tue, 26 Mar 2019 16:42:00 +0100

Part of ~~SIO-1928~~.

Jobs should report the predicted amount of RAM that they need. This should probably be a new environ parameter ("required_ram" is proposed), but another part of this issue is investigating whether there is already some similar parameter, and if there is, whether it can be used for ~~SIO-1928~~.

The list of all jobs can be found in `setup.py` of sioworkers package (`sio.jobs` list).

[SIO-2071] Modify job schedulers to take into account RAM amount

Tue, 26 Mar 2019 16:38:05 +0100

Part of ~~SIO-1928~~.

Right now various jobs are scheduled between workers using only WORKER_CONCURRENCY parameter. Existing schedulers should be modified to take into account WORKER_RAM parameter for workers and environ['required_ram'] for jobs.

[SIO-2070] Add information about available RAM to worker config

Tue, 26 Mar 2019 16:40:41 +0100

Part of ~~SIO-1928~~.

Right now, the worker config defines WORKER_CONCURRENCY parameter which is calculated from both CPU number and (RAM / average RAM for a job). This parameter should be split into WORKER_CONCURRENCY that only depends on CPU count, and WORKER_RAM that declares the amount of RAM that can be used.

The default value should leave some RAM for OS usage.

[SIO-2069] Upgrade to Django 2.0

Thu, 24 Jun 2021 12:33:22 +0200

It requires Python 3.

Note: update python version check in default_settings.py.
Note: update dependencies like django-two-factor-auth to use latest supported version by Django 2.0.

[SIO-2068] Upgrade to Django 1.11

Mon, 22 Mar 2021 17:44:11 +0100

Note: in default settings we should change required python version.
Note: update dependencies like django-two-factor-auth to use latest supported version by Django 1.11.

[SIO-2067] User session management.

Mon, 27 Apr 2020 16:28:15 +0200

Use django-user-sessions (https://django-user-sessions.readthedocs.io/en/1.5.3/installation.html) to display list of user sessions with ability to terminate them. Example app here: https://example-two-factor-auth.herokuapp.com/ (src code here: https://github.com/Bouke/django-two-factor-auth/tree/master/example).

Another feature: add option to make sessions last until closing the web browser.

Note: use GeoIP2. If all sessions will originate from our internal network, please contact oi-admins to resolve this.

Note: preferably locate this option between "Two factor authentication" (order=150) and "Logout" (order=200) entries in user menu.

[SIO-2066] Enforce 2FA for contest admins

Mon, 27 Apr 2020 16:28:16 +0200

For security reason, add to contest settings option "Contests admins must have 2FA enabled.". Otherwise, their contest admin privileges will be revoked until they enable 2FA. They should see message that they need to enable 2FA while having activated contest to which they have admin privileges (analogous to: https://gerrit.sio2project.mimuw.edu.pl/#/c/2953/3/oioioi/base/templates/base.html).

PS following the rule "sum(security mechanisms) = min(security mechanisms)", consider if effective superusers should have revoked privileges or not (I guess effective superusers shouldn't be an exception).

[SIO-2065] Scheduler: equal priority for user, not task.

Mon, 27 Apr 2020 16:28:30 +0200

During some contests (for example Potyczki Algorytmiczne), competitors have unlimited number of submissions. Some could think "I won't score this problem anyway, so I'll submit a lot of submissions just to fill submission queue and make other competitors wait longer for results". Therefore, scheduler should take into account who is owner of the submissions and give equal priority for each user, not for submission.

[SIO-2064] Trivia module

Mon, 27 Apr 2020 16:28:31 +0200

liveranking module provides site with real time visualisations. During last Potyczki Algorytmiczne we came up with idea of adding trivia to it (quickly hacked version here: https://www.facebook.com/potyczki/photos/pcb.1873197056041937/1873195482708761/?type=3&theater). For each, let's say 7 updates of donuts, there is one extra with full screen trivia. Trivias should be added in contest administration menu.
Consult oi-admins if you want to have access to quickly hacked version of code that provides this feature.

PS we can add some configurable options to liveranking: for how long are displayed donuts, for how long are displayed trivias, after how many donuts updates we should display trivia.

[SIO-2063] File compression in filetracker

Tue, 26 Mar 2019 16:39:03 +0100

Szkopuł filetracker's database weights a lot (hundreds of GB). After compressing it with xz (LZMA2), the size is reduced 2-4 times AFAIR.

Objective is to store files in filetracker compressed with xz.
Extra objective: compare what occupies more space - compressed file or not compressed version of same file. Some directories gain weight from hundreds of MB to some GB - what is against logic since xz header is 10-100B I guess while the disk block size should be 4 kB (maybe there were a lot of empty files?).

[SIO-2062] Provide a way to inspect sioworkersd queue

Mon, 27 Apr 2020 16:28:49 +0200

Sioworkersd keeps one or more queues of tasks, and groups of tasks, etc. in its internal state, which affects how the tasks are sent to workers and how the results are sent back to the requestor.

To ease debugging and monitoring performance of sioworkersd, it's useful for admins to be able to inspect that state. There's already a manage.py command for that: `manage.py worker queue`, but it doesn't provide any useful information.

The command calls `get_queue()` method of sioworkersd RPC API, which returns `unicode(scheduler)`. However, none of the schedulers implement __unicode__ in a meaningful way.
The PrioritizingScheduler tries to stringify its queues, but they themselves don't provide a meaningful __unicode__. The FIFOScheduler seems to have its __unicode__ reference an undefined vraiable (possibly broken during refactoring), but I haven't tested it.

Another thing to consider would be displaying the sioworkersd queue information in the worker management web interface of sio2.

[SIO-2061] Allow upsolving

Mon, 27 Apr 2020 17:58:11 +0200

During ONTAK camps, we have to create eternal contest so participants can submit their solution after the round ends. Adding possibility to submit solutions after the contest ends would solve this problem.

I hacked something similar. There is a new field with "upsolving" score in result models. I also created a new kind of submission, but I'm not sure if this is the best approach.

[SIO-2060] Generate tests only if needed

Mon, 27 Apr 2020 18:06:05 +0200

If the package has input generator, why don't we just generate tests if someone submits a solution to this problem? The tests can be cached for example for one day or something and then removed.

We have to be sure that generator is deterministic (generate tests twice during package processing), we can also keep md5 of tests if needed.

This should solve a lot of problems with memory.

[SIO-2059] In the model solutions table, show also memory limit and amount of points for each test.

Mon, 27 Apr 2020 16:27:51 +0200

Model solutions view (for example https://szkopul.edu.pl/problem/22133/models), shows only the time limit.

[SIO-2057] Creating a team in admin mode is causing an error if we add membership at the same time

Tue, 26 Mar 2019 16:38:48 +0100

Just try to add a new team and add some members at the same time.
The following error should occur:

  File "/home/rno/sio2/venv/local/lib/python2.7/site-packages/django/forms/models.py", line 411, in validate_unique

  File "/home/rno/sio2/oioioi/oioioi/teams/models.py", line 45, in validate_unique

When we first add a team and then try to add its members, it works.

[SIO-2056] In ACM mode problem score has red label.

Mon, 27 Apr 2020 16:28:56 +0200

Instead of cool colorful labels with a number of points, in ACM contests, we have the red label with time and amount of bombs. Please change color to green at least.

[SIO-2055] Add support for output-only tasks

Tue, 18 May 2021 15:08:13 +0200

There are several problems from international olympiads that use output-only format, i.e. contestant can submit only output files for given inputs (in zip format or txt). Right now SIO does not support such tasks.

[SIO-2050] Submission limit should be visible in submission form

Relates — Tue, 26 Mar 2019 16:37:17 +0100

Right now there is no indication of submission limit on the submission page. If a user is not aware that the limit exists, and may be pretty strict, they might send a lot of "test" submissions, and hit the limit in a short time (see SIO-1679).

It would be nice to give a simple "X attempts left" indicator on the submission page.

[SIO-2049] Differentiate colours between "OK" and "Partially OK"

Relates — Tue, 3 Mar 2020 16:08:21 +0100

When the problem grader assigns only a fraction of points for a test, it is still displayed as "OK" with green background, which could be misleading. It would be better to write "Partially OK" or just "OK" with a different bg colour (say, yellow).

I mean, when the grader outputs:
"OK
some message
50"
then the program is assigned 50% of the points. It is a different situation from the one when it gets 100% of the points but still the only difference in the display is in the footnote to the test case. Some of the contestants find this situation confusing.

[SIO-2048] Allow customizing the disqualification message

Mon, 25 Jan 2021 19:44:25 +0100

Right now, the disqualification message says something like "By the power of the contest rules you are going to be disqualified.", and it's hardcoded. This isn't 100% accurate, as the disqualification process depends on the rules of the specific contest.

Eg. for OI, the juree would like the messageay to say "According the the Organizational Principles of the Competition, the proposition to disqualify you will be presented to the Head Comitee". On some other contests, a different message may be appropriate.

There should be a way to change this message, preferably on a per-contest basis.

[SIO-2047] Add contribution guide

[SIO-2046] Styling: problem packages table is not fully visible

Tue, 3 Mar 2020 16:08:33 +0100

There are two issues with a visibility of a problem packages list at /c/CONTEST_NAME/admin/problems/problempackage/

1. It's partially covered by a "Filter" column if the browser window isn't wide enough (e.g. it applies to laptops with a standard 1366x768 resolution, with the window maximized).

2. And on the other hand it's width is capped at a certain value with the table's content horizontally scrollable - even though all of it could fit with no "hidden overflow" on a wide enough screen (e.g. also standard fullHD monitor)

[SIO-2045] Page not found error after deleting a contest

Tue, 26 Mar 2019 16:37:30 +0100

If you are viewing the admin page with an active contest (so that admin site is prefixed by the contest id in the URL) and you delete that contest, you get a 404 error afterwards instead of for example being taken into proper admin page without the contest prefix.

[SIO-2044] [Zeus/PA] Allow Zeus problem ID edition

Mon, 27 Apr 2020 16:28:32 +0200

Sometimes we need to rejudge submissions, but after getting access to new Zeus instance, the problems have new IDs in Zeus system and SIO2 allows us to specify these IDs only during uploading the tasks packages, so the only way to change them later is updating them manually in database via django shell or db shell.

We can also consider if we want to allow edition of Zeus system ID. Actually it can be easily hacked out by changing appropriate Zeus IP in settings.py. But adding this field to the form shouldn't require much work after adding the first field.

Tue, 26 Mar 2019 16:39:40 +0100

Currently, the number of testruns a participant can submit for a particular problem is limited by the probleminstance's submission limit. The same limit is used for regular submissions.

It would be nice to be able to set a different submission limit for testruns than for normal submits.

[SIO-2041] When uploading problem packages .tar.gz extension fails

Mon, 27 Apr 2020 16:27:43 +0200

It's because the archive unpacking recognises archive format by file extension, but because of usage of temporary filename it's getting only the part of the extension after the last dot, so something.tar.gz is recognised as ".gz" format which is not supported.

Simple solution: use ".tgz"
Better solution: make the file format hint consider extensions with multiple parts?

[SIO-2040] [Zeus/PA] Invalid validation of allowed languages

Mon, 27 Apr 2020 16:28:05 +0200

PA contest controllers allows C and C++ while Zeus problem controller allows only C++. On submission view you see both C and C++ (since it is PA contest and some problems allows both C and C++), but there is no later check if specific problem allows chosen language what can result in accepting submission in C for Zeus problem which is wrong behavior.

[SIO-2039] su to inactive account logs you out

Tue, 3 Mar 2020 16:08:37 +0100

Sometimes you want to su as some person and usually you know his/her name. Some people have multiple accounts with some of them being inactive and you don't know which are active and which aren't. So you just pick random one and... if you have tried to su as an inactive user, you will be logged out (I also got redirection loop sometime, when trying to su on some admin pages). There's no message about what happened.

1) There should be no redirection loops
2) You should get an error that chosen user is inactive (or even exclude him/her from search result). After getting an error, you should still be logged in as you.

[SIO-2038] 2FA

Mon, 27 Apr 2020 16:28:51 +0200

Add 2 factor authentication to OIOIOI - use time based tokens. Later, we can also add U2F.

Moreover, add a new setting "enforce 2fa for superadmins" to settings.py (maybe add setting for contest admins privileges and also specific option in contest settings, too). With this option enabled, superadmins have full access if and only if they have enabled 2FA. Otherwise they have privileges of regular users.

I plan to work on this when I'll get some free time. If it isn't ready before March 2018, you can just ignore this sentence or ping me :)

[SIO-2035] Require explaining the reason when reporting a forum post.

Fri, 8 Jan 2021 14:30:56 +0100

Currently, reporting a forum post takes a single click on a link next to the post.
There's also no way to provide an explanation of why the post was reported.
This makes it very easy to accidentally report some posts, while making it hard for contest admins to go through the reports and decide which ones are legitimate and which are not.

Some users (participants and juree members alike) have been complaining about this:
https://sio2.mimuw.edu.pl/c/oi25-1/forum/62/654/

One way of solving it would be to make the "report" link redirect to a form where the user could fill in the reason for reporting the post, and confirm that they indeed want to make the report. The user could also go back if they clicked on the "report" link by accident.

[SIO-2027] Remove leftover grappelli CSS classes

Relates — Tue, 26 Mar 2019 16:39:28 +0100

There are some leftover `grp-*` CSS classes from Grappelli (which we stopped using when we moved to Django 1.9), mostly in `oioioi/programs/templates/programs/admin/tests_inline.html` but also in some other files.

Some things that are usually done with special HTML tags (eg. tables) were done with divs with special `grp-*` class, which doesn't work anymore, since Grappelli is no longer present. Other parts of styling may also be broken.

I guess it'll be necessary to find out what each of those classes did, and how to replace it with something that works with bootstrap.

ValueError: Tried to save contest with empty controller

Probable cause:
If there are no rounds specified, this code saves the contest even if it's not supposed to (commit=False):
https://github.com/sio2project/oioioi/blob/master/oioioi/contests/forms.py#L73-L82

Git blame suggests it's been there since the very beginning, I have on idea why this issue didn't appear before.

[SIO-2019] Tests fields in the Change problem instance view don't appear as they should

Mon, 27 Apr 2020 16:28:23 +0200

Steps to reproduce:
1. Upload a package in Contest Administration > Problems.
2. After it is processed, return to the Problems section and click Edit problem on the newly uploaded package.

The tests fields should be displayed in a table, like in previous versions of OIOIOI, but instead they are shown under each other, completely unstyled.

[SIO-2018] Submissions imported from main links to PL version despite ENG set

[SIO-2016] Add more selenium tests

Mon, 27 Apr 2020 16:28:51 +0200

We've recently added support for selenium tests in OIOIOI. They're great for testing integration, simulating real contests, users behaviour etc.
Right now there's only few tests so it would be nice to add some more. It's also a good way to learn about OIOIOI's components!
More details here: http://oioioi.readthedocs.io/en/latest/sections/misc.html#selenium-tests.

[SIO-2015] Directories in supervisord.conf should be wrapped in "".

Mon, 27 Apr 2020 16:29:13 +0200

In supervisord.conf there are a lot of filesystem paths passed as arguments to services like:
-c {{ settings.FILETRACKER_CACHE_ROOT }}
or
{{ PROJECT_DIR }}/manage.py

They should be wrapped in "" (if it does work in supervisord.conf.template) as if they contained spaces they wouldn't be treated as one argument (such behaviour could result in serious damage e.g. overwriting important files).

It will be more secure and will allow us to run any process including solutions in many programming languages (i.a. rust, python, java, ...).

[SIO-2003] Faster oitimetool

Tue, 26 Mar 2019 16:40:11 +0100

Consider using perf: https://perf.wiki.kernel.org/index.php/Main_Page

Problems:
- Linux only
- Counts rep asm instruction as one (current oitimetool counts number of iterations of rep instructions)
- Note: if we will count rep instruction as one, we should change statute of Polish Olympiad in Informatics

Solves/improves:
- performance (perf is faster than pin)
- we can use newer kernels (pin requires some old one)
