Failing to add @aimane-chnaif as reviewer 🤷

aimane-chnaif · 2023-08-16T20:16:21Z

@jjcoffee please take first round of review and test

aimane-chnaif

@Antasel please fix lint. Also, as agreed, we can skip the case of _ prefixed email inside italic markdown. This will make code much simpler.

@aimane-chnaif
I've fixed lint

as agreed, we can skip the case of _ prefixed email inside italic markdown. This will make code much simpler.

Also restored autoemail & quote rule's order and some tweaks on Italic rule
according to the change, autotest cases are updated

jjcoffee · 2023-08-17T09:05:35Z

@aimane-chnaif Can you clarify what you mean by the case of "_ prefixed email inside italic markdown"? Do you mean:

Email with leading underscore ([email protected]) wrapped in italic markdown: [email protected]_
Normal email wrapped in italic markdown: [email protected]_

I don't think this would be expected behaviour and would result in a regression. If you wrap a normal email ([email protected]) in italic markdown it should just be italicised and linked. cc @aimane-chnaif

Agreed. If we just change parsing order of autoEmail and italic, should this be fixed?

@Antasel Let's add all of these in test case. Github markdown seems to have different logic

[email protected] -> [email protected]

[email protected] -> [email protected]

[email protected] -> [email protected]

[email protected]_ -> [email protected]_

[email protected]__ -> [email protected]__

[email protected]_ -> [email protected]

[email protected]_ -> _[email protected]

[email protected]__ -> [email protected]_

[email protected]__ -> [email protected]

@Antasel Let's add all of these in test case. Github markdown seems to have different logic

[email protected] -> [email protected]

[email protected]_ -> [email protected]

[email protected]_ -> _[email protected]

[email protected]__ -> [email protected]_

[email protected]__ -> [email protected]

those cases are already covered in Expensify/App#17387 (comment)
so there is no need to restore the changed order of autoemail and italic rule, just leave it as it is.
I will revert last commit.
How you think ? @jjcoffee

@Antasel Yes I think that's the only way to get the behaviour we want here. I don't think it's possible to isolate a fix for [email protected]_ from [email protected]_, which is what @aimane-chnaif was initially talking about.

@aimane-chnaif you meant "the case of _ prefixed email inside italic markdown can be skipped" is following case ?

[email protected]_ -> _[email protected]
after parsed, underscore is not contained in email
if so, it can be done by only moving autoemail rule after italic rule. no need extra tweak in italic rule
cc: @aimane-chnaif

I am fine with it. @jjcoffee you too?

@Antasel Sorry I'm not clear, what would the result be for [email protected]_?

That expected to be parsed as [email protected] but _[email protected] actually, @Antasel you meant correct?

@aimane-chnaif I thought you wanted _<em><a href="mailto:[email protected]">[email protected]</a></em> after parsed.
currently with Expensify/App#17387 (comment), it is parsed as <em><a href="mailto:[email protected]">[email protected]</a></em>

That's what I don't care too much. Either result is fine to me

jjcoffee · 2023-08-17T09:07:06Z

__tests__/ExpensiMark-HTML-test.js


    testInput = '~*[email protected]_*~';
-    expect(parser.replace(testInput)).toBe('<del><strong><em><a href="mailto:abc@gmail.com">abc@gmail.com</a></em></strong></del>');
+    expect(parser.replace(testInput)).toBe('<del><strong><a href="mailto:_abc@gmail.com">_abc@gmail.com</a>_</strong></del>');


Same here, I don't think this is the expected behaviour.

jjcoffee · 2023-08-17T10:13:58Z

@Antasel Let's add some of the markdown tests from ExpensiMark-HTML-test.js into the Tests section of the PR so it's easier to visualise how it will work for markdown cases. For example [email protected]_ would be useful, maybe some of the multiline ones too?

jjcoffee · 2023-08-17T13:02:27Z

@Antasel Please can you fix the lint issues again.

aimane-chnaif · 2023-08-17T13:04:21Z

@Antasel I just noticed that your commit signature is unverified.

jjcoffee · 2023-08-17T13:13:30Z

@Antasel See here at point 10. It might be easiest to close this PR and open a new one where you make new signed commits, then you'll get a "Verified" badge here:

Antasel · 2023-08-17T13:20:42Z

thanks, I will do it now,
but I remember I followed it before

jjcoffee · 2023-08-17T13:27:11Z

The result is not correct for [email protected]:

Also doesn't work with it on its own. Can you check @Antasel?

aimane-chnaif · 2023-08-17T13:34:11Z

The result is not correct for [email protected]:

Also doesn't work with it on its own. Can you check @Antasel?

This is more like a bug in Expensify/App#16762.
If it's not quick fix, can be out of scope.
As it is parsed as email in current app which is wrong, I won't say this is regression.

jjcoffee · 2023-08-17T13:41:43Z

@aimane-chnaif Are you saying it's incorrect to parse [email protected] as an email, or just the one with the leading dot? The former is correct as far as I know! Current production:

Antasel · 2023-08-17T13:46:25Z

@jjcoffee I am getting correctly

Antasel · 2023-08-17T13:51:21Z

@aimane-chnaif commit signature has been verified

aimane-chnaif · 2023-08-17T13:53:18Z

@Antasel is it now ready for review?

Antasel · 2023-08-17T13:57:46Z

we need to check why @jjcoffee is getting incorrectly

Antasel · 2023-08-17T13:59:02Z

@jjcoffee which platform did you check it on ?

jjcoffee · 2023-08-17T13:59:36Z

@Antasel I think all your commits need to be signed - you've only signed the new one. I think that's correct right @aimane-chnaif?

I will retest soon - I might have some cached node_modules messing things up 😄

aimane-chnaif · 2023-08-17T14:00:49Z

@Antasel there's still unsigned commit. All commits should be signed

jjcoffee · 2023-08-17T14:03:16Z

@Antasel It fails when I add it as a test, so it must be an issue with the regex:

aimane-chnaif · 2023-08-23T12:05:16Z

'Maximum Regex stack depth reached'

This was reported before and now marked as fixed - Expensify/App#21266

jjcoffee · 2023-08-23T12:07:29Z

@Antasel Can you try merging main in case the issue is resolved by the PR @aimane-chnaif mentions?

Antasel · 2023-08-23T12:11:32Z

noted, let me try

Antasel · 2023-08-23T12:17:42Z

@jjcoffee
my test was on the main where the PR had been merged

Antasel · 2023-08-23T12:23:29Z

@Antasel I'm confused, are you saying that autolink is trying to parse the domain part of this email:

yes, sure
if we disable autolink rule, no error is happened

Antasel · 2023-08-23T12:30:37Z

@jjcoffee @aimane-chnaif
you can try at your side.
on latest version of expensify-common, please limit domain level length to 10 on MARKDOWN_EMAIL regex, then autolink rule is not parsing even simple invalid email [email protected] , causing the error.
maybe #559 's contributor should check it again

Antasel · 2023-08-23T12:42:55Z

I am getting this warning, but ios app gets stuck for 10 seconds

Antasel · 2023-08-24T08:18:12Z

@aimane-chnaif @jjcoffee
I've posted more reasonable bug report (Expensify/App#21266 (comment)) on #21266 .
The issue is out of current PR's scope.
I think we can move forward.

jjcoffee · 2023-08-24T08:46:22Z

@Antasel Agree it looks like a separate issue. From what I understand, any invalid email (like a super long email that's over the length limits) will not be parsed by the email rule so the autolinker tries to parse it and fails because of issues with the autolink rule. I think it's worth reporting this as a separate bug on Slack.

I think next steps here are to add some additional manual tests:

Try to login with an invalid email + an email at the limit (e.g. just below length limit)
Navigate to Settings > Profile > Contact Method > New Contact Method, try an invalid email

I will run some platform tests today, but otherwise it's ready for review. We're running close to the 9 day limit for merging, so let's try and get this merged today! cc @aimane-chnaif

Antasel · 2023-08-24T09:11:09Z

@jjcoffee noted
Could you please make video of iOS, mobile safari, desktop Platform to save time, whilst testing ?

jjcoffee · 2023-08-24T13:27:41Z

@Antasel Actually we can ignore tests for sign-in as if FE validates, BE will still return that it's an invalid email (the error message is just slightly different). Also, there's now(?) a length limit on all email input fields, so you can't enter an email >254 chars anyway 😄

Can you add Navigate to Settings > Profile > Contact Method > New Contact Method, try an invalid email as a test to the description here please? Maybe specifically for a@a.abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijkl

Antasel · 2023-08-24T15:00:01Z

Can you add Navigate to Settings > Profile > Contact Method > New Contact Method, try an invalid email as a test to the description here please? Maybe specifically for a@a.abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijkl

I've added it and updated demo video.
now Could we move forward ?
@aimane-chnaif @jjcoffee

jjcoffee · 2023-08-24T15:20:23Z

@Antasel Thanks! Please also remove the // Overall length too long item in the invalid emails list since this will always fail the test on iOS.

jjcoffee · 2023-08-24T15:41:53Z

Tests well, just waiting for the Android build. I think this is ready for review @aimane-chnaif - please prioritise as we're getting close to the 9 day limit. Thanks!

Android test added! @aimane-chnaif Do you think you can review today?

aimane-chnaif · 2023-08-25T12:40:51Z

This is not expected. Italicize should not happen when there's non-blank character before starting _ and after ending _

jjcoffee · 2023-08-25T12:49:06Z

I guess this is to do with putting the autoEmail rule after the italic rule, since a~*[email protected] would otherwise be parsed by autoEmail as this being the email part: [email protected]. cc @Antasel

jjcoffee · 2023-08-25T12:51:34Z

@aimane-chnaif Actually this is current behaviour on main, so unrelated to this PR:

aimane-chnaif · 2023-08-25T12:52:24Z

Nvm. No matter this is bug or not, I think this can be out of scope as already happens on staging:

All of these should still be invalid, right? Why not retain these tests?

Though looks like at least the last one is already covered by the test on 184

Right. They are not intentionally removed but maybe overwritten since these are recently added in #562 and #563 after @Antasel prepared these cases for testing.
@Antasel let's add these back. I just tested these cases and still work fine.
And also pull main

@NikkiWines @aimane-chnaif
The cases have been restored.

We used to have the quote rule run before the italic rule. Changing that order caused an invalid markdown rendering for cases like:

_Msg then a > quote_
