The new ACE editor introduces full support for emojis (and, thereby, UTF-16 characters with high- and low-surrogates). Hence, we can remove our custom fix.
Further, this update will allow emojis to be used in pair programming sessions.
Previously, we were at an ACE editor published between 1.1.8 and 1.1.9. This caused multiple issues and was especially a problem for the upcoming pair programming feature. Further, updating ace is a long-time priority, see https://github.com/openHPI/codeocean/issues/250.
Now, we are not yet updating to the latest version, but rather to the next minor version. This already contains breaking changes, and we are currently interested to keep the number of changes as low as possible. Further updating ACE might be still a future task.
The new ACE version 1.2.0 is taken from this tag: https://github.com/ajaxorg/ace-builds/releases/tag/v1.2.0.
We are using the src build (not minified, not in the noconflict version), since the same was used before as well.
Further, we need to change our migration for storing editor events. Since the table is not yet used (in production), we also update the enum.
* This commit refactors the table used to store events.
* We also use a UUID as session identifier in the synchronized editor to support multiple concurrent tabs opened by the same user.
* Further, we renamed some methods to make them easier to distinguish.
This commit mainly changes the color definitions. Mostly, those changes are semantically equally, but there are a few changes that occurred to align the color scheme within the app.
This is useful to remove any handlers, e.g., when submitting an exercise. Hopefully, we will see less Javascript errors due to cumbersome behavior with these changes...
Also, I am cleaning up unused event handlers. The `showOutput` method doesn't seem to be used, we should observe this in the future.
Closes CODEOCEAN-KQ
Even though not reproducible locally, we had some errors captured through Sentry where the Tooltip was opened on the (already hidden) run button. This resulted in an error by the Bootstrap library. Most likely, the issue was caused by some race condition.
Fixes CODEOCEAN-BA
Previously, removing an UTF-16 character (such as emojis) required pressing the backspace twice. This was caused by ACE only handling single UTF-8 characters.
Fixes CODEOCEAN-GC
Hypothesis: When unloadAutoSave was called, we first saved (causing this.autosaveTimer to become null) and then tried to clearTimeout on this variable (= on null). This probably never worked?
Hopefully closes CODEOCEAN-B5
Previously, a user-defined test (those run with "Test" instead of "Run") would cause a flash message and a Sentry error if anything was printed to StdErr. As this might happen during user code execution (and therefore is no error), we remove this warning. All existing errors are already caught (compare with enum status in testrun.rb), so it's fine for now.
Fixes CODEOCEAN-BT
