Sim is an open source platform for carrying out algorithmic contests and programming classes. This repository contains all Sim projects as a monorepo.

sim-project's Issues

Web client broken on minor browsers due to a small compatibility issue

TL;DR

Many minor distributions still use Chromium 83 but produced by the builder/optimizer script.js involves logical nullish assignment (??=) operator which is supported by Chromium 85 and above.

A brief introduction of myself

With respect, gentleman. I am Adam Maleszka, a graduate of the ID class of the XIII'th High School in Szczecin. In the 7th grade I became a "laureate" of the Junior IT Olympics (laureate in quotation marks, because that year the final did not quite take place). In practice, my fascination with computers reaches even the 1st grade though. I love competitive programming, networking, security and cryptography, GNU/Linux and the whole Open Source community.

Chromium compatibility issue

I've been using Linux for five years and managed to choose my final Linux distribution, GNU Guix. It's ingenious, it's powerful, but also out-of-date a bit, especially with qtwebengine 5.15.2 (Chromium 83). It is worth noting that qtwebengine 5.15.2 is in many distributions, even on Debian Bullseye.

After inspecting the script.js, the reason seems to be in logical nullish assignment operators which is not supported by Chromium 83:

It is surprising to me, especially since the source code appears:

https://github.com/varqox/sim/blob/b115a4e858dda1288917243e511751b835c28482/src/web_server/static/kit/scripts.js#L238-L247

Does any compilation tool optimizes the above code for the newer standard, Chromium 85? It looks like a small tweak in the building system and SIM on my browser will work back.

Installation hangs at running custom install script

I've decided to try hosting a local instance of sim for whatever reason, and while installing I've been following the steps given in the README (steps from the section Instructions: release build and installation step by step).
However, at step 7 (meson install -C release-build) the command shoots out a lot of output, then hangs with the last message being Running custom install script '/usr/bin/sh -c <sim-install-dir>/release-build/setup-installation "$MESON_INSTALL_DESTDIR_PREFIX"'. Is this step supposed to take >1 hour, or is something happening?
For information, everything before this happened went fine with zero errors whatsoever.

Running Arch Linux x86_64, with all required packages installed and updated.

404 should be fixed quickly

"Fix contest submit error 404 after refresh" has certainly a too low priority in the TODO list. When going back in history from submitting code, I get a 404 error. It is extremely annoying, because I'm often resubmitting code. Fix this asap pls!!1!.

The EDIT problem does not work.

Hello,
I installed the SIM on my server. I added a problem and would like to edit it. I can not do this, HTTP error code:

501 - This feature has not been implemented yet.

It's the same with submission and solutions. What to do?
Regards.
Sorry for my English.

Add ranking

Teachers cannot edit their accounts

Every time I try to update my teacher account I get an error: 'type: Type selects option to which you do not have permission'. This error occurs even if I don't change anything.

Add round editing

Create documentation

Disregard non-printable characters

When reading outputs of programs disregard non-printable characters to prevents situations like the one in the picture from happening.

Problem with adding problem

Hello,

While adding the problem, I received the error:

Caught exception: execvp ('zip') - 2: No dry file or directory (thrown at src / lib / simlib / src / spawner.cc: 18)

In addition, I am asking for an example of a package.

Thank you and best regards.

SHA256

Write sim SHA256 implementation.

Inconsistency when clicking on a problem's name in contest view vs round view

When I open a contest and click on "Problems" then problem name it takes me to the pdf problem statement. When I click on the round name beforehand, however, it takes me to the problem's page (the page of a given problem in a given contest, not the general system-wide problem page).

Try out Intel pintool in judging process

Update readme

• add Arch installation instructions (package names, needed step after pacman'ing mariadb)
• correct Ubuntu package name: mariadb -> mysql
• make -j 4 -> make -j $(nproc)
• explain what should one write when "It will ask for MySQL credentials" (or at least write the default options)
• change git clone command to clone develop branch
• server.conf file -> sim.conf

db_new.php, wut?
