TIOJ 3.2.2

This is a bug-fix release. For a direct installation setup, migrating the database is needed.

• Fix overflow on programs using >=2TiB of VSS

TIOJ 3.2.1

This is a bug-fix release.

Important Upgrade Note

Because of a bug in the migration script in v3.2.0, if you have previously upgraded to v3.2.0, the display type in some sample testdata might be wrong. You can fix them by either:

• Run RAILS_ENV=production rails db:rollback && RAILS_ENV=production rails db:migrate to automatically fix it.
  NOTE: If you have manually set the display type of some of the sample testdata after migrating to v3.2.0, running this will reset all the changes!
• Run rails sample:identify_non_plaintext [detail=1] to list all sample testdata that is either non-plaintext or previously marked as non-plaintext, and manually check them.
  Note that there may be some plaintext testdata marked as non-plaintext (those containing parentheses), and also some non-plaintext testdata not marked as non-plaintext (those containing HTML escape sequences).

The bug won't occur if you didn't upgrade to v3.2.0. Just directly upgrade to v3.2.1 if that's the case.

Changes & Bug Fixes

• Add plain markdown format for sample testdata, and rename the pre-v3.2.0 display behavior from "markdown" to "Raw HTML"
• Fix incorrect plaintext sample testdata detection in migration (#44)

TIOJ 3.2.0

This version includes some enhancements and bug fixes. See Wiki for upgrade instructions. For a direct installation setup, the following steps are needed:

• (Strongly recommended) Upgrade tioj-judge to v2.1.2 for bug fixes
• Upgrade Ruby to v3.3.7
• Upgrade JavaScript packages
• Migrate database
• Configure [path-to-tioj]/scripts/trim_sessions.sh to run periodically (daily is recommended) to avoid database getting too large
  • Example crontab settings: 30 3 * * * [path-to-tioj]/scripts/trim_sessions.sh to run it at 3:30 AM every day
  • Note that running this script for the first time will take a long time if the sessions table is big.

The deprecated rails credentials:edit configuration method is removed. Migrate to settings.yml if you are still using it.

Enhancements

• Change sample input/output to be displayed in plaintext by default (#40, #43 by @OmeletWithoutEgg)
  • A new option Sample Display Type can be configured to "markdown". Old samples containing non-plaintext will be preserved using this option. Run rails sample:identify_non_plaintext [detail=1] to list all sample testdata that includes non-plaintext.
