> b4hand: Are you interested in writing a fix and a test for this?

Yes I am. Any ideas? Maybe a try catch kind of, but in JavaScript of course.
b4hand: I would start with seeing if you can create a failing test case. A try/catch might be a suitable fix, however :whimboo or :ato may have a better suggestion.
Assignee: nobody → bforehand
Try/catch is fine with me, and we might want to combine it with a possible failure as result of calling `file.exists()`

Bug 1408066 - Addon.js install fails if path is incorrect.

https://reviewboard.mozilla.org/r/191316/#review196498

Sorry for picking up the review from you Dave. But I thought this way Benny has the time to update the patch until you are around tomorrow.

Please only wrap the constructor of `File` into the try/catch, and use a better error message for that case. Right now we would loose the stack frame in case the file does not exist.

Why do you add this line here again? You have it already above, so make use of the variable after moving its declaration out of the try/catch block.

Just use the plain xpi file name here. This is also a relative path and will cause an error to be thrown. Maybe update the test name to "test_install_with_relative_path"

It was my understanding that a the variables defined within a try/catch are only available within that scope.

That's why I said "after moving its declaration out of the try/catch block". :)

Also please note that when working with mozreview you should best reply inside this tool by navigating to the created issue first. Doing that will keep all the comments together.
You also created a complete new commit in that patch series. I wonder who that is possible at all. Please check that and if necessary fixup/squash all the commits into a single one.

Ah yes...I apologize. First time using git cinnabar. I'll fix it.

It's not a bad path, but not an absolute one. See the documentation on MDN:

https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Reference/Interface/nsILocalFile#initWithPath()

So a better error message would be:

"An absolute path is required for the addon."

I didn't miss them but it was a bit difficult to understand what you meant from just 1 sentence. 

This should be ```test_install_relative_path```? The first augument for ```os.join``` could be something like ```'relative-path'```, and then of course the new error message.

Henrik meant that a more accurate name for the test would be "test_install_with_relative_path". He's also suggesting that you can recreate a relative path by simply specifying self.addons.install("does-not-exist.xpi"). There is no need to use os.join at all.

It would be better to reference an existing addon, to not actually overlap with the path not exist failure. But as I can see, Benjamin did that with the latest update.

Indentation should match the rest of the file.

Hmm my knowledge of JS6 has failed me. I thought since we will access this variable later it needed to be a ```var``` and not a ```let```. Works with ```let``` though.

r=me with the comments fixed.

Exception messages should not contain a proposal how to get it fixed, but explain what was wrong. Also you are not adding the addon path anymore.

Here an example: `${path} is not an absolute path.`

If the length of the line is shorter then 79, then leave all in one single line.

This change is unnecessary, and not needed because the line length doesn't exceed the maximum amount of characters.
