As reported in bug1647039comment87, the Decrypt button presents some inconsistent behaviour we could improve.

  • Improve discoverability: As of now, the button and notification message is showed inside the Message Security popup. This was done on purpose to prevent the issue of having multiple notification stacked in the message pane. We could explore the possibility of exposing this notification outside as a regular NotificationBar, or implementing the notification counter on top of the encryption label like in the proposed original design.
  • Reload information: We should force a full message reload once the user clicks on the Decrypt button to properly update the message security info and prevent visual inconsistencies.
Summary: Improve usability of the Decrypt message action → Improve usability of the Decrypt message action (applies to PGP inline encrypted messages)

I noticed another problem that I'm trying to tackle.
If the .eml file is opened from File > Open > Saved message, OpenPGP is properly loaded and the encryption button is showed.
If the message is opened directly from the attachment, nothing shows up.

Attached patch 1672851-inline-decrypt.diff (obsolete) — Splinter Review

This is a WIP patch which takes care of a couple of things:

  • The Decrypt bar is now a proper notification.
  • Upon clicking Decrypt, the encryption status is properly updated.

This doesn't solve the issue when opening the message directly from an attachment.
I think the problem comes from the messenger.openAttachment method, which is a C++ method (nsMessenger::OpenAttachment).
https://searchfox.org/comm-central/rev/ccdaa27822e254ca10d9c576c9a3723e141a05ae/mail/base/content/msgHdrView.js#2060

Instead, if we open the file from File > Open > Saved message, everything is handled in JS here: https://searchfox.org/comm-central/rev/ccdaa27822e254ca10d9c576c9a3723e141a05ae/mail/base/content/mailWindowOverlay.js#2312

What should be the approach here?
Should we check if the content type is a message and open it via JS? Could we properly convert the URI to be readable?

You could try it but I suspect it can't just be opened "like that" via js.

I'd think this and at least the one for Exchange should also move to a notification since the messages will be more or less unusable without that information.

Sounds good.
With these changes, the inline notifications that will remain inside the security popup are Import Key and Missing Signature alerts.
I think this is good.

On yeah, I'm well aware this is not gonna be an easy change.

Kai, I'm pinging you to see if you have any insights of what we could do for the problem highlighted in comment 1.

Should we force open .eml files via JS instead of C++, or is there a way for those attachments to be scanned for encrypted parts, and therefore properly triggering the encryption information?

Attached patch 1672851-inline-decrypt.diff (obsolete) — Splinter Review

This patch takes care of using the MozElements.NotificationBox for both unable to decrypt, partially encrypted, and broken exchange errors.

Unfortunately, I wasn't able to manually test the 3rd scenario.
Does anyone have the ability to send me an email to simulate the broken MS exchange error?

Comment on attachment 9183912 [details] [diff] [review] 1672851-inline-decrypt.diff Review of attachment 9183912 [details] [diff] [review]: ----------------------------------------------------------------- When I get a notification about partial encryption, then (try to) decrypt, I get two notification boxes stacked on top of each other: first the "Reminder: the message shown below is only a subset of the original message" and below that, "The secret key that is required to decrypt this message is not available". I would expect only one notification bar, messages hidden under each other by priority if need be, but here since decryption failed also there shouldn't ideally be the reminder at all. Can you add a test that this is working? For notifications, you can check examples e.g. in https://searchfox.org/comm-central/rev/458e8a4488e9a3eccf4602f64f2145da387ebb25/mail/test/browser/composition/browser_attachmentReminder.js#351 ::: mail/base/content/mailWindowOverlay.js @@ -3155,5 @@ > get msgNotificationBar() { > delete this.msgNotificationBar; > > let newNotificationBox = new MozElements.NotificationBox(element => { > - element.setAttribute("flex", "1"); sure this can go?

Note that for successful decryption, use standard keys, see bug 1669014.

I sent you email.

Repairing of that message worked previously, but repairing is no longer offered with 78.4

ok, I discovered the repair button inside the openpgp button; repairing using that button works.

(In reply to Alessandro Castellani (:aleca) from comment #1)

(a) If the .eml file is opened from File > Open > Saved message, OpenPGP is properly loaded and the encryption button is showed.
(b) If the message is opened directly from the attachment, nothing shows up.

I don't understand the difference.
Can you please describe in more detail what (b) is about?

Are scenarios (a) and (b) about the same, or about different messages?

(In reply to Kai Engert (:KaiE:) from comment #12)

I don't understand the difference.
Can you please describe in more detail what (b) is about?

(b) A single click on the .eml attached to the message you're currently reading. Opening an .eml directly from the list of attachments doesn't trigger the OpenPGP feature.

Are scenarios (a) and (b) about the same, or about different messages?

I'm talking about the same attached message.
But in scenario (a) I saved the message locally and then opened it via the menu File > Open > Saved message.
In scenario (b) I clicked directly on the attachment in the message pane. As I wrote in comment 2, clicking on an attached email message uses a C++ method to fetch it and to open a new window.

(In reply to Magnus Melin [:mkmelin] from comment #8)

I would expect only one notification bar, messages hidden under each other by priority if need be

I was expecting that as well, I'm not sure if that's the expected behaviour of the notifications or there's something wrong with our implementation. I'll investigate.

but here since decryption failed also there shouldn't ideally be the reminder at all.

Yeah, that makes sense. I'll postpone the reminder only if the decryption fails. The original code has the same issue, showing the reminder regardless the decryption outcome.

Can you add a test that this is working?

For sure.

  • element.setAttribute("flex", "1");

sure this can go?

I converted the "mail-notification-top" into a vbox as I noticed that multiple notifications were being added inline.
I wonder if that's an issue we always had and never noticed since we don't usually stack notifications.

All right, a little update here.

  • Opening .eml attachments is a whole other beast that we will need to tackle at some point in a follow up bug.
  • I opened bug 1674013 as I stumbled upon that issue while working on this patch. The issue is not caused by this patch.
  • I opened bug 1673958 as I noticed an incorrect implementation of the NotificationBox. I already fixed the part touching this patch.
  • I created 2 tests to cover the broken MS-Exchange and the PGP inline partial decryption. I'm running these test with a couple of emails that users sent me to recreate the issue, but of course since those contain real data and addresses, we can't use them in the patch.

How can I update our test .eml files to simulate those 2 scenarios?

Attached patch 1672851-inline-decrypt.diff (obsolete) — Splinter Review

Meanwhile, I'm uploading the patch for a review.
The two new tests currently fail because I'm loading placeholder messages, waiting for some help in creating those variations I wrote above.

I've manually crafted the messages you requested, see attachments.

According to this bugs title, maybe bug 1673798 is related.

Thanks Kai for those files, perfect.
The test for the broken MS-Exchange is disabled as it fails due to bug 1674013.

A little update to the patch before pushing as I found out that buttons inside MozElements.NotificationBox accept the "l10n-id" attribute, therefore no need to update any string for a safer uplift.

The tree has been orange enough to make it hard to notice, but this broke the "draft notification" - the bar you should get when looking at a draft.

I was wrongly cleaning up all the notifications at the end of the decryption process.
With this follow up patch, the OpenPGP code only handles the removal of specific notifications.

I'm gonna create a single patch for easier uplift to beta, and also properly update the variation for 78.

I'm suspecting this also is causing
comm/mail/test/browser/message-header/browser_phishingBar.js | A promise chain failed to handle a rejection: can't access property "getElementsByTagName", msgFrame.contentDocument is null - stack: getBodyElement@chrome://openpgp/content/ui/enigmailMessengerOverlay.js:1372:5

.... which has been showing up, but not quite consistently. Filed bug 1674895 about that.

This patch is corrupted, it fails to apply with an error message in line 191. Did you manually edit a patch to create this file?

The patch seems corrupted in many ways. If you diff v3 and v4, you'll see many lines that change a single space. And for the two test .eml files, I'm guessing you have changed the line endings from CRLF to something else. OpenPGP messages must be CRLF.

I think you've simply tried to combine the three commits into one, with the adjusted setTimeout call. I didn't see other changes.

I've applied those locally to a esr78 tree, and then used hg export.
This is the resulting patch.

I'm not sure why I see a change from the earlier v4 patch and this one in the eml files, but I've verified that this patch will create files that are byte-identical with the file that was commited on trunk.
