Our instance used for template rendering needs a lock to ensure there is
no race condition where rendering happens on 2 threads at the same time.
This can lead to local poisoning which can cause unexpected results in
emails
Previous to this fix we were leaking methods on the internal action view
template class per render.
This caused email generation to be very low and a steady memory leak in the
application in sidekiq when sending out emails
The behavior change is new to Rails 6 so this fix does not need to be
backported into stable.
Zeitwerk simplifies working with dependencies in dev and makes it easier reloading class chains.
We no longer need to use Rails "require_dependency" anywhere and instead can just use standard
Ruby patterns to require files.
This is a far reaching change and we expect some followups here.
In some very rare cases CssParser could be loaded but CssParser::Parser not
this ensures we check for the actual constant we plan to call for concurrent
digest generations
This feature adds the ability to customize the HTML part of all emails using a custom HTML template and optionally some CSS to style it. The CSS will be parsed and converted into inline styles because CSS is poorly supported by email clients. When writing the custom HTML and CSS, be aware of what email clients support. Keep customizations very simple.
Customizations can be added and edited in Admin > Customize > Email Style.
Since the summary email is already heavily styled, there is a setting to disable custom styles for summary emails called "apply custom styles to digest" found in Admin > Settings > Email.
As part of this work, RTL locales are now rendered correctly for all emails.
This feature is off by default and can can be configured with the `email_total_attachment_size_limit_kb` site setting.

This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Minor fixes to add Rails 6 support to Discourse, we now will boot
with RAILS_MASTER=1, all specs pass
Only one tiny deprecation left
Largest change was the way ActiveModel:Errors changed interface a
bit but there is a simple backwards compat way of working it
We had quite a few cases in core where inputs are being mutated as a side
effect of calling a method.
This handles all the cases where specs caught this.
Mutating inputs makes code harder to reason about. Eg:
```
frog = "frog"
jump(frog)
puts frog
"fly" # ?????
```
This commit is part of a followup commit that adds # frozen_string_literal
to all our specs.
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.

- The test_email job is removed, because it was always being run synchronously (not in sidekiq)
- 34b29f62 added a bypass for critical emails, to match the spec. This removes the bypass, and removes the spec.
- This adapts the specs for 72ffabf6, so that they check for emails being sent
- This reimplements c2797921, allowing test emails to be sent even when emails are disabled
Migrates email user options to a new data structure, where `email_always`, `email_direct` and `email_private_messages` are replace by
* `email_messages_level`, with options: `always`, `only_when_away` and `never` (defaults to `always`)
* `email_level`, with options: `always`, `only_when_away` and `never` (defaults to `only_when_away`)
We can only be sure that an email is sent when we get a mailer in
`ActionMailer::Deliveries`. A couple of tests were actually incorrect
because it didn't flow through our email sender where there are more
conditions in determining whether an email is sent or not.
If you reply to an email with the word "mute" a topic will be muted
If you reply to an email with the word "track" a topic will be tracked
If you reply to an email with the word "watch" a topic will be watched
These ninja command can help advanced mailing list ex-users, saves a trip
to the website
* Enable user email PM when posting to group or replying to topic via email
* remove extra line
* Add test and fix snake_case
* Only reenable email_private_messages for PM replies
* FEATURE: add indication if incoming email attachment was rejected and inform sender about it
* include errors for rejected attachments in email
* don't send warning email to staged users
* use user object instead of user_id in add_attachments method
* Add possibility to add hidden posts with PostCreator
* FEATURE: Create hidden posts for received spam emails
Spamchecker usually have 3 results: HAM, SPAM and PROBABLY_SPAM
SPAM gets usually directly rejected and needs no further handling.
HAM is good message and usually gets passed unmodified.
PROBABLY_SPAM gets an additional header to allow further processing.
This change addes processing capabilities for such headers and marks
new posts created as hidden when received via email.
This updates tests to use latest rails 5 practice
and updates ALL dependencies that could be updated
Performance testing shows that performance has not regressed
if anything it is marginally faster now.
Ignores the site setting "find_related_post_with_key" and always tries to honor the `In-Reply-To` and `References` header for emails sent to a group.
The senders email address must be included in the `To` or `CC` header of a previous email sent to the group and the `Message-ID` of that email must be included in the current email's `In-Reply-To` or `References` header.
* `rescue nil` is a really bad pattern to use in our code base.
We should rescue errors that we expect the code to throw and
not rescue everything because we're unsure of what errors the
code would throw. This would reduce the amount of pain we face
when debugging why something isn't working as expexted. I've
been bitten countless of times by errors being swallowed as a
result during debugging sessions.
This change allows email-clients to show threaded views of mails as
expected. Apparently most algorithms expect the message ids of mails
in the Reference-header-field to be sorted such that they build a
traversal through the thread, so the oldest (original) message being
first, then its child, grandchild and so on until it arrives at the
message id that the "new" mail (that is to be sent) is the reply to.

If the stuff in brackets would be the message ID, the References-Header
field of a message that is a reply to [1-2-1] should look like:
References: 1, 1-1, 1-2-1
Discussion took place in:
https://meta.discourse.org/t/e-mail-threading-in-ml-mode-does-not-work-in-thunderbird
Main information taken from:
https://www.jwz.org/doc/threading.html
* store time it took to index message in DB (to find performance issues)
* ignore listserv specific files
* better examples for split_regex
* first email in mbox shouldn't contain the split string
* always lock the DB in exclusive mode
* save email within transaction
* messages can be grouped by subject and use original order (for Listserv)
* adds option to index emails without running the import
Although 407a23663d will send rejection
messages for unrecognized errors, sometimes processing the email will
raise an error which has a blank message.
This commit:
1. Shows rejected emails which have already been processed and contain
a blank error in /admin/email/rejected
2. Replaces new blank error messages with the error type
The mail class seems to handle mails sent with Content-Transfer-Encoding: 8bit
somewhat weirdly: It decodes them (to utf-8), changes the raw source to base64,
and does not modify the Content-Type:charset= header.
This leads to Discourse trying the message encoding (in my example ISO-8859-1)
first, and if that does not contain any unparseable characters, it uses that.
Sadly, in ISO-8859-1, every byte sequence is valid.
Fix this by always trying to decode as UTF-8 first. The probability of someone
using another encoding that cleanly (but wrongly) decodes as UTF-8 should be
fairly low.
currently, Discourse uses '---' in its notifications to
separate the signature with unsubscribe links etc. from
the body of the message.
The RFC standard defines '-- '.
https://www.ietf.org/rfc/rfc3676.txt (4.3)
The problem has been discussed in:
https://meta.discourse.org/t/previous-replies-separator-is-not-rfc-compliant/39410
And an incomplete fix has been added a year ago:
86819f08c3
The separator is important, because some mail clients strip off the
signature automatically in replies if the signature is recognised as such.
