When trying to save plugin settings at /plugins/scribd, I get a 500 error.

This makes them keyboard inaccessible. Some examples: Adding other contact (from profile) or Adding another New email address (for notification preferences).

Creating a quiz, I click Find a question.
Select a question from teh question bank.
Later I add the same question to the quiz from the question bank.

I take the quiz as a student, giving different answers to each instance of the question.

The second version seems to overwrite the first: both versions of the question show the second's answer, and are scored with the second's scoring.

I realize this isn't a likely user workflow, but not desirable behavior anyway....

The major functionality of the page should be included in the section that is designated role="main". Currently, most of this functionality is found in the inappropriate section with role="complimentary". This obscures the main functionality of the page and is exacerbated by the fact that the "main" section comes after the "complimentary" section in the render order, so if an AT user skips to the main content, they totally bypass all the major actions of the page.

note:

I created a module named locked <script>alert('module name');</script>

When I go to add an item to the module,the page alerts 'module name'.

When the modal dialog opens, it again alerts 'module name'.

I have been trying to get this installed for a few weeks now. I have also been documenting my installation procedures and have it down well until I get to this setup. When I run

RAILS_ENV=production rake db:initial_setup

I get the following rake aborted!
You have already activated rake 0.9.2, but your Gemfile requires rake 0.8.7. Consider using bundle exec.

I am using ruby 1.8.7 (2008-05-31 patchlevel 0)
rubygems 1.8.5
rails 2.3.11

Not sure how to proceed with the installation.

I have a course titled Demo - <script>alert('demo');</script>

If I go to my inbox and compose a message for that course, and click on Select Recipients, the page alerts demo, but only the first time I click that button.

The tabs in course settings appear as just a set of links. I'd suggest making these more semantic and accessible by coding these as actual tabs and letting the AT users know this via ARIA. The expected behavior would be that only the active tab is tabbable. When a user tabs to it, they can then use the left/right arrows to navigate the rest of the tabs in the UL. By using tabpanels to relate the tab content to the tab, users will clearly understand the association between the tab and the content on the page. This will also help users tab through the page content efficiently.

Internet Explorer 8 does not allow assignment submissions via file upload. It prompts to download a file named "file.text" when clicking on the submit button. Firefox works fine. IE works on the Instructure demo site, but not community edition sites.

On my test build I created a course named Course-101<script>alert('foo');</script>

When I click on Grades, it alerts foo twice, and then fails to load with this js error:

unterminated string literal
[Break On This Error] 2-07:00","context_type":"Course","title":"<script>alert('foo');

I added my API information to the scribd config file and tried to run RAILS_ENV=production rake db:generate_data but since the instructions had me change the owner of the config files the rake command fails with this error:
(in /var/rails/canvas)
rake aborted!
Permission denied - /var/rails/canvas/config/security.yml

To fix the problem I simply changed the owner of the files back to my username i.e:
sudo chown canvasadmin config/*.yml
I re-ran the rake command and it worked but then I got this error:
Rails Error: Unable to access log file. Please ensure that /var/rails/canvas/log/production.log exists and is chmod 0666. The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.

So I went back and performed the same thing on all the other files the instructions had me change i.e:
sudo chown -R canvasadmin config/environment.rb log tmp public/assets public/stylesheets/compiled Gemfile.lock

I re-ran the rake command and restarted apache and everything configured fine.
Just remember to re-run the chown commands with canvasuser to get things back in order.

Is there a simpler method to ensure the rake commands run successfully without changing file owners eachtime? Does the rake command need to be ran each time a config file is changed or can I just restart apache?

Thanks,
Tyler

I don't see any indication that the notifications that appear at the top of the page would be announced to AT users. I'd suggest using the roles of "alert" or "status" so that they will be announced. Due to the visual treatment, it appears that these should be announced.

Additionally, the links on these are inconsistent and, some of them, extremely non-descriptive. When you add memebers, the notification that a member has been added has <a href"">#... this doesn't help an AT user know whether to click this link or not.

The form at https://mysite.com/accounts//settings submits over HTTP even when the page was loaded with HTTPS.

Creating a quiz without an assignment group causes the error below when publishing the quiz and breaks course exporting.

Cannot cleanly cast "null" to integer (AssignmentGroup#id)

1. Create new course
2. Create new quiz
3. Publish triggers error
4. Course export fails

I'm seeing some cascading styles that are resulting in a .64em font size in the Add Assignment dropdown menu. This is quite difficult to read, even with good eyesight.

Even using a files domain, it is still possible to steal the ajax auth token.

It takes 2 file uploads. The first does the theft, and it looks like this:

... some actual content

After the attacker knows the url to that file, they upload a second file that looks like this:

Loading that document requires the victim to log in a second time, which might stop someone who's really paying attention, but once they do both the canvas app and the first file are in the same domain, so the content can be read.

Hi,

when i run this

RAILS_ENV=production rake db:initial_setup

at the end it asks the email address and password for the administrator account. But when i enter the details it gives the following error..

"Problem creating administrator account. no mac address candidates found."

any ideas why this error occurs ?

I'm running through the production install instructions on the wiki. Got to the part where I setup the db.

$ RAILS_ENV=production rake db:initial_setup

It works fine until I get to the point where it wants to create a delayed_jobs table...

== CreateDelayedJobs: migrating ==============================================
-- create_table(:delayed_jobs)
rake aborted!
An error has occurred, all later migrations canceled:

Access denied for user 'canvas'@'localhost' (using password: YES)

(See full trace by running task with --trace)

I created the canvas user in mysql using the Production Install Wiki. I think I can just GRANT the canvas user more permissions in MySQL, but wasn't sure why this didn't work since I followed the MySQL setup instructions correctly.

Am using Quick Start directions to set up Canvas in following environment:
-Mac OS 10.6.6
-MySQL server version: 5.1.48
-Apache 2.2.15

I followed instructions and everything seemed to install correctly:
-installed RVM as a user
-installed Gems in user folder
-installed Bundler

When installing the Bundler, got the following errors:

I am having some trouble using my SSL certificates when trying to configure Canvas. Whenever I try to use the .pem that was given to me by my CA and the .key file that I generated, in the canvas file under the sites available folder, I get an error saying the "Webpage isn't available please try again later" when trying to load in Google Chrome in Windows 7. But when I use the default SSL files that are given in the Production Start Wiki, it works just fine, but I get the certificate files aren't trusted.

I generated the .pem and .key file using the openssl command in Ubuntu 10.04 and GoDaddy is my certificate authority.

Thanks,
Mike

When creating a quiz, the user can use the formatting dropdown to add H2s to the instruction text. When published, this text falls under the heading "instrcutions:", which is an H3.

Certain account settings do not appear to go in to effect until Ruby is restarted. For example, if I uncheck the "who can create new courses" boxes on the account settings page, students can still create a new course. Restarting Ruby (passenger, unicorn, mongrel, etc.) fixes the problem.

When editing a course page, the "Insert Content into the Page" header is improperly nested as an H4. It should be an H3 under the H2 of "Page Tools". The following subheaders should be H4s.

Of course, the heading titles seem a little odd when you read it as Page Tools> Insert Content into this page ... not really sure what "tools" are available.

The Jobs control panel page at /jobs sends some ajax requests. The protocol for these requests is HTTP even if the jobs page is loaded over HTTPS.

If the server responds with a 301 to the HTTPS address, the redirect will not be followed. The jobs tables are never populated.

I tried to upgrade from an earlier pull in the year to the latest stable release and after getting the database upgraded and everything else working I am now getting these javascript errors.

Uncaught ReferenceError: jQuery is not defined common.js:328
login:154Uncaught ReferenceError: $ is not defined
login:168Uncaught ReferenceError: $ is not defined

I have a course in my account named <script>alert('Course Name');</script>My Course

When I visit http:///accounts/1 it alerts 'Course Name', and there's this on the bottom of the page, below the powered by Instructure logo:

","My Course","My Course","Demo - alert('demo')"]} }); // get rid of this lookup part and it will use ajax queries to that serviceUrl above. I just figured this would be faster // and since we dont have that many users per institution we can afford to send it in a pageload. } });

It looks like that part is caused by this data structure not escaping a </script> tag in it, which the browser is putting a higher priority on than closing the quote:

autoComplete = $courseName.autocomplete({
...
lookup: {"data":[3,4,1,2],"suggestions":["Demo - <script>alert('demo');</script>","<script>alert('Course Name');</script>My Course","<script>alert('foo');</script>My Course","Demo - alert('demo')"]}
});

The fact that "My Courses", "Current Groups" and "Needing Grading" are H2s on all pages is odd. Semantically, the heading structure should speak to the particular hierarchy of the page. I'd urge you to reexamine your heading structure on page by page, making sure that it will assist AT users in understanding that particular page's hierarchy. The first suggestion would be to not make the labels in drop-down menus page headers.

The accounts -> users page sometimes shows duplicate entries in the list of users. The same user, with the same id, shows up more than once.

Since the notification preference settings are coded as tables, rather than interactive elements (like radio buttons), they are inaccessible to keyboard users. I'd suggest going with semantic code here and using css to style the elements to look however you want them to appear.

There is a typo on Lines 145 and 156 of the ProfileController located in app/controllers/profile_controller.rb.

On an AJAX request that triggers a validation error it tries to output the pseudonym errors using the local variable "pseudonym" instead of "pseudonym_to_update" as used in the rest of the code. The same problem occurs on both lines. You can trigger the error by trying to change your password to something under 6 characters.

format.json { render :json => pseudonym.errors.to_json, :status => :bad_request }

should be

format.json { render :json => pseudonym_to_update.errors.to_json, :status => :bad_request }

when i was installing bundle we are getting error as cannot locate gem file as bundler gem is installed already, could any one help me regarding how to solve and continue ....thanks in advance

Unchecking “allow multiple attempts” for a quiz doesn’t seem to be respected. Students are still able to take the quiz multiple times.

The web conference creation page at /courses//conferences will list web conference types even if they have been disabled at /plugins

I mentioned this in the google group, but I wanted to document it here as well.

There is a problem with Canvas' SAML single logout implementation. Canvas does not responsd to IdP initiated SLO requests with a LogoutResponse, but instead redirects to /logout, and creates a new LogougRequest.

See the link above for more info.

Thanks!

I got the url required for non-authenticated homework file viewing down to this:

http://files.anise:8080/files/12/download?verifier=d58163ba9efaa2873ddc98a66d316dbf308d761a

I then tried to download file 13, which was another student's file with this url:

I can't seem to use the Chat feature of the hosted Canvas version with the keyboard or with screen reader software. Am I missing something?

I followed the Quick Start guide and while Canvas runs, the specs do not. After fixing the "encryption key is too short" error, many tests fail with "Could not find table 'delayed_jobs'". I'm running the tests using rake spec:models.

What's the proper way to setup Canvas so the specs run without error?

It would greatly help with accessibility if the landmark aria roles that are designating the different sections of your page had aria-labelledby attributes pointing to the appropriate headings.

I'm finding multiple locations where is being used for labeling non-input elements. This is non-semantic and can be quite confusing for AT users. One example of this is on the profile page, where "full name:", "profile name:" and "timezone" are labels regardless of whether the corresponding inputs are displayed or not. The proper way to handle this would be to have the switch to a or something when the corresponding input is toggled to display:none.

When commenting on a discussion displayed on the Recently Activity screen... you have a link to "more options". The link takes you away from the Recently Activity screen, however, any text your may have previously entered in the textarea is cleared. The link suggests that more options may be shown, however, the outcome is different. The link should probably be removed, or if it must stay, any text already inputted by the user should follow to the brand new screen.

ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

This installed gem successfully, but got bunch of "no definition" messages for ri and RDoc documentation (e.g. No definition for next_result, No definition for field_name... etc)

So close....

The previously entered url shows up automatically whenever I bring up the "Link to Website URL" dialog. This feature seems only useful if I was using the same url constantly. I found myself having to override the default url with the correct one. Can this be left blank? Thanks!

With the absence of visual context, there are many cases where the actionable elements don't contain enough information for a user to figure out what they would do. I'd suggest using titles or offscreen text to make these more accessible. One example are the "And also..." links on the notification preferences page. What can a user expect will happen when they click those?

It would be useful with a few lines on how to get started - commands to get the gems installed, database set up etc. Even for people familiar with RoR, there are always some details that might be different.

I'm getting an error on installation on Ubuntu. Can't quite figure it, though I thought it might be in my mysql config.

RAILS_ENV=production rake db:initial_setup
(in /var/rails/canvas)
rake aborted!
syntax error on line 23, col 8: ` queue:'

(See full trace by running task with --trace)

Any ideas?

As a student, I added this content to a discussion forum:

Now, as an admin, every time I visit that discussion forum, I become user 11. If that account id doesn't have access to the course, I get permission denied messages, if it does belong to that course, the admin could inadvertently post content as that user.

I use a Cr-48 for school and the class I am in has a context module for each week. When I pull up the course all the modules are initially expanded until the javascript gets far enough along that it knows to collapse them. This usually takes a while to get fully loaded. It's annoying because I initially see way too much information and I potentally overscroll as a result of the modules collapsing.

Instead, if this info was processed server side, I would be closer to the info I'm looking for and I would avoid overscrolling when everything finally does collapse (and the small overhead of processing the collapse would be removed).

I went ahead and made some very minor changes to allow the collapsed/expanded state to be determined server side.

I'm not sure how these minor changes affect anything else in the system because I have limited rails experience, and even less experience with canvas. I was also very conservative with how much javascript I removed. I'm not sure what code was only used for the collapsing and what code is used elsewhere. It may even be the case that I broke something I'm not aware of :D

Let me know any thoughts about this change and what might need to be done to make this better.

I should also note that when I'm using my full-size laptop and desktop computers, this isn't nearly as annoying, although I still notice it happening ;)
