User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20180123231643

Steps to reproduce:

Step 1:
Create an HTML file with the following content:

<!DOCTYPE html
><meta charset="utf-8"
><title>Test to include Javascript named with non-ASCII characters</title
><script src="測.js"></script
><p>Test to include Javascript named with non-ASCII characters</p>

Step 2:

Create a Javascript file 測.js with the following content:

console.log("a test");

Step 3:

Open the HTML file with Firefox, and then see what the web console output.


Actual results:

It outputs text with a unreadable URI-encoded filename.


Expected results:

It should have output text with a readable URI-decoded filename; or at least it should be customizable through about:config for the user to choose which they would like to see, and default the value to "showing decoded".
Also, the full path of the file name will be displayed when the pointer device is hovering over the filename. The full path is shown in a URI-encoded way like the filename, so it needs to be decoded too. Besides, if the full path includes a non-ASCII domain name, it's shown in Punycode, which needs to be depunycoded.

(I wondered if this is related to bug 987069...  Looks like the latest news is that bug 1380617 made the Punycode domains appear, which is slightly better that before, but still sub-optimal.  So, perhaps Punycode detection and conversion makes sense in DevTools UI side...?)

Yes, I agree with you.

bug 987069 became actually defunct when bug 1380617 was resolved.

The remaining work is in the DevTools side.
This is the screen after patching part 1.
Now all the filename and hostname are readable as Unicode characters if they are non-English.

After patching part 3, the tree pane in the Storage shows the Unicode domain name together with the raw domain name, but the table pane keeps the raw domain name unchanged. as from the perspective of client programmer, cookies and other storages are storaged according to the raw name instead of the decoded name, so I intentionally leave the raw domain name in the table unchanged, which is a special case particularly in part 3.

Thanks for working on this. From your screenshot, I notice the storage inspector is inconsistent with the other two tools you've patched. The storage inspector now displays both human-readable and punycode, while the other tools display just human-readable. Is that intentional ?

Also, could you create a shared module in devtools/client/shared/ to avoid duplication ?

It is intentional. Because the table may show more than one domains, although they will all belong to one common parent domain, it may not be very appearant to match the level in the long Puyncode characters at a first glance,especially when the domain name consists more than two domain levels. So I labeled the Unicode domain name together with the Punycode domain name to help developers more easily match domains.

I originally wanted to create a new shared module, but then I found there is a ready-made shared IDL interface nsIIDNService which converts a Punycode domain to a Unicode domain, and it's fairly easy to use, we just need to call its method convertToDisplayIDN and that's all. And also, converting URI-encoded filename is also fairly easy by just calling decodeURIComponent. So I think the code in the different tools are not actually duplicated, creating a shared module wouldn't help in the sense of avoiding duplication and reducing the number of the code lines, but it does help in the sense of naming a easy-to-remember method because the code of using nsIIDNService is a very long line and hard to remember.

So, yeah, I will create a new shared module providing easy-to-remember functions for this.

The patches are going through a refactoring, so please don't review it now, I'll upload a refactored one soon.
I was testing the Network panel using STRs from comment #0 and I am not sure if I see the actual issue. See the attached screenshot with highlighted areas where the file path/name is. No patch applied. What's wrong?

From the screenshots Zhang provided, only the domain name is broken for the netmonitor, not the filename.

Both the Unicode filename and the Unicode domain name are broken in the web console.

In the network monitor and the stroage inspector, only the Unicode domain name is broken.

BTW, since you uploaded the screenshot, I would like to talk about the header content, I personally think it might be better to keep the request URL in the header panel to be the raw URL rather than the decoded one, because the header content is used to represent actually transferred data. So I prefer this one to be the raw. Please see bug 1450435 I filed.

This could happen if the user is going to visit a URL with an invalid UTF-8 code.

For example, http://example.org/%E8%A9%A6.html is a valid URL, but http://example.org/%E8%A9.html is invalid, because %E8%A9 is not a valid UTF-8 code.

> could we add tests for data: URIs ?

getUnicodeUrl is not intended to be used for a data URI. Base64 URIs are fine because they don't contain %, but textual data URIs would be broken. So I don't think it's correct to call it for a data URIs. Maybe I should document part 1 to make it clear.

Good point.

Bug 1448553 - Part 3: Decodeds Punycode-encoded international domain names in the Network Monitor so that they are displayed as human-readable Unicode text.

https://reviewboard.mozilla.org/r/233064/#review239116

Thanks for working on this!

The patch looks good in genereal, I am just worried about the support for the DevTools Launchpad.
See my inline comment

This require loads a module that uses chrome API, specifically:

const idnService = Cc["@mozilla.org/network/idn-service;1"].getService(Ci.nsIIDNService);

The Network monitor panel related code (UI) is currently chrome API free - using only standard (web) content API, and so it can run within a tab (read more about the Launchpad [1])

I think that we should use the same technique as e.g. for the `open-request-in-tab.js` module in the Network panel.

There are two versions of that module (two version, two implementations):
devtools/client/netmonitor/src/utils/open-request-in-tab.js
devtools/client/netmonitor/src/utils/firefox/open-request-in-tab.js

The first chrome API free
The second using chrome API

[1] https://searchfox.org/mozilla-central/source/devtools/client/netmonitor/README.md

So, I think there should be two version of the `unicode-url.js` module.

This might be done as a follow up, but we should at least track this, since it breaks the Launchpad.

Honza
@Nicolas, what's do you think about the Launchpad support? See my previous comment.
I know the support for Launchpad is not the top priority atm, but I think that we should at least track issues.

Thank you for the information.

If we are going to implement a Chrome API free version of the `unicode-url.js`, I would suggest we use a ready-made Punycode decoder instead of writing one from scratch, as there are time-tested robust Javascript implementations.

https://github.com/bestiejs/punycode.js

This one seems practicable from the programming perspective, but it uses the MIT License, I have not enough knowledge on these licenses, so I am not sure if it's allowed to be included in a MPL project.

I think I would opt for a mock of this module, where each function returns what it was passed. The mock should then be declared in the webpack config.
Given the status of the launchpad at the moment, I'd rather not look too much for a feature-parity replacement. We can always fix it later if we feel like the launchpad workflow is important for us.

I agree with Nicolas. Having empty mock of the module would be good
enough for me too + file a follow up, so we can track the rest.

I found a bug in part 1: The "Filter output" input couldn't correctly filter Unicode filenames, actually it still filtered filename by URI-encoded filenames even the filename was displayed as Unicode. Part 1 of this commit fixed this bug, now that the "Filter output" input works for Unicode filenames.

Sorry, typo. I meant part 2 when I said part 1.
Found one unnecessary newline I made in part 2, patches pushed again.

Please be aware I pushed twice in several minutes.
Talking about mochitest, I have difficulty figuring out how to do mochitest for Unicode filenames.

Since mach is buggy for handling Unicode filenames(maybe as is mochitest), so a file with a Unicode filename cannot be considered, so I am wondering how we can mochitest a URL request with a Unicode filename? Right now, I haven't found there is any ready-made mechanism which simulates a Unicode URL with a Unicode filename, I wonder if there is one, if not, do we need to implement such functionality in some underlying code?

build/pgo/server-locations.txt has some non-ascii host names you can use.
If you need a non-ascii path name then you can probably do that using an sjs file, see

Thank you very much for the information. Server-side script is really what I am looking for.
Mochitests have been added for the Web Console(Testing ).

The changes in the Network Monitor and the Storage Inspector actually only changes text labels. No functionality invovled. We just need to make sure we're not breaking the exisiting mochitests in the two devtools, and I think it's enough.
BTW, the Network Monitor had supported the Unicode filename before this bug, but it was buggy for filtering the Unicode filename, that is, it already was broken before this bug, so I'll file a new bug for fixing that bug instead of fixing it in this one.
From some results of mochitests broken by this commit, I found that URI datas are possible to be passed in some cases, so I added support for the data: URIs in getUnicodeUrl, and also added xpcshell-based unit tests for data: URIs.

Would the following work ?

Do we need to consider the case where the data scheme is uppercased(E.g. DATA: or Data:)? 

If so, then we need to make a lowercased or uppercased conversion before calling startsWith("data:"). Since the function is used mostly for URLs, not for data: URIs, it would decrease the performance for URL conversion in this function. So I would like to suggest we keep the original code.

Thanks for the patch!

Looks good to me. Just one thing, please move/rename the mockup module:

from:
devtools/client/netmonitor/src/utils/unicode-url.js

to
devtools/client/shared/webpack/shims/unicode-url-stub.js
  
This way, it'll be ready to be used by other panels too (not only the Network panel can run on top of the Launchpad). 
  
R+ assuming the above is resolved and try is green.

Thanks,

Could I simply move
devtools/client/webconsole/test/browser_webconsole_log_file_filter.js
to
devtools/client/webconsole/new-console-output/test/mochitest/browser_webconsole_filename_filters.js ?

After looking into the code in browser_webconsole_file_filters.js, I believe it is just used to test filtering Javascript's outputs, not filenames. But the old browser_webconsole_log_file_filter.js is used to test filtering filenames(I.e. used to test bug 923281, which proposed adding a feature for searching filenames).

So, the two files serve different purposes. So I suggest simply moving devtools/client/webconsole/test/browser_webconsole_log_file_filter.js to the new directory.
Of course, the old APIs in this file, if any, will be changed to new APIs.
> Could I simply move

Sure, as long as we keep a consistent style with the other tests from this directory.
Issues mentioned above have all been addressed.

This one has been fixed, I pushed twice, and this one relates to the former push.
Jan,

FYI, Please note that the unicode-url-stub.js is not removed(I originally added it in part 3, but now I added in part 2 instead of part 3, that's because webpack.config.js in the Web Console also needs it.), but due to the limitation of the review diff, it "mistakenly" shows as if the file is removed.
I just triggered dt and dt-e10s mochitests on all Linux64

Once if the try is all green, I'll continue to trigger mochitests on all platforms.
Try is all green except two timed-out failures, no functionality-related failure:

https://reviewboard.mozilla.org/r/234124/#review240474

Thanks for adding the test. However, it seems that this is only testing the output, and not the filtering per-se. We should make sure that filtering work as expected.
Also, let's not move the files but copy the ones we need.

we shouldn't make change here.
Could we copy the test file (with `hg cp`) instead of moving it ?

we try to not have the bug number in the filename anymore. Could you rename it when doing the copy ?

I don't understand those assertions: we don't do any filtering between them, and I find it hard to follow what should be filtered or not from this function alone

Could we move this as the top of the file, since it the block that describes best what is happening in this test ?

Unless I'm missing something, the doesn't seem to test message filtering at all, but only that the message are displayed as expected.

The test should be completed to make sure that filtering does work as intended.

They are used to test filtering filenames, not the output contents themselves.

Both `testFilteringOutputsWithAsciiFilename` and `testFilteringOutputsWithAsciiFilename` test filtering messages together with filenames.

For example, HANZI_1 is used both in an output message and a filename, while HANZI_2 is used only in a filename. `test2.js` is a file, and is also a string in test1.js.

But I'll refine the test cases to make them more understandable.
Typo.

s/They are used to test filtering filenames, not the output contents themselves/They are used to test filtering filenames, and the output contents themselves
Sorry to insist Zhang, but I triple checked the patch again and I can't see where we do set a text filter (i.e. fill the filter input with the filenames we want to check).
Previously this was done in `setStringFilter` , which was called several times.
Here the `findMessages` call only assert what is on the output, not any text filter the user might set.

Ah, I see what you meant.

Sorry, I misundersood `findMessages` without looking into the code of `findMessages`. I thought it's used to fill the filter input, and after replacing `findMessages` with `setStringFilter`, I got no assertion failure, which made me believe what I thought was right.

Attachment #8965384 - Attachment is obsolete: true
I rewrite the test file for testing the Webconsole's filter input from scratch.

The tests were devided into different files, now the tests are integrated into a new file, and the new test file tests filtering for both the output contents and the filenames.

The filter input test files in the old directory are untouched.

Thanks a lot, this is taking shape nicely.

let's avoind having globals and instead pass the hud as function argument

(Diff revision 1)

so, before starting filtering things and making assertions, we might want to make sure all the messages are displayed.
Since we use the console api, we can't really tell when we open the console that they have been displayed. On some slow machine this might take some time (and thus, create intermittents failure on our CI).

What we know though is that the console api guarantee the order of logs. So here we could wait until there is a "winter" and a "\\u51ac" messages using waitFor and findMessage

```js
// Let's wait for the last logged message of each
// file to be displayed in the output.
const lastSeason = SEASONS[SEASONS.length - 1];
await waitFor(() => 
  findMessage(hud, lastSeason.english) &&
  findMessage(hud, lastSeason.escapedChinese)
);
```

Or we can wait until we do have a certain count of messages. Do what you prefer :)

could we inline the function content in here ? Since we only have one function, and that it is used only once, I find it easier to have the whole test in the add_task block

instead of checking the number of messages, could we check that the expected message are indeed displayed (with findMessages for example) ?
Because here, we might have the right number bit the wrong messages if something goes wrong.

we can directly return the result of the querySelectorAll since we don't rely on CSS to hide messages (they are not in the DOM anymore)

Ah, I am personally used to the style, I tend to write my own HTML documents without any non-semantical white spaces and line breaks, and for the purpose of ease CSS to prevent them from being unintentionally visible in some cases. Since it's definitely not the case, and some people may not be used to it, I changed it to the typical style.
The new patch addressed all the issues mentioned above and is rebased against mozilla-central

nit: this is only used in one test, so I'd prefer if this was moved back into this test file. (We try to not clutter head.js too much).
We can move it back here later if we feel the need to use it in multiple tests.
