afd2ace0dc Apply inverse edge edits after committing primary object edits
Summary:
Fixes T13082. When you create a revision (say, `D111`) with `Ref T222` in the body, we write a `D111 -> T222` edge ("revision 111 references task 222") and an inverse `T222 -> D111` edge ("task 222 is referenced by revision 111").

We also apply a transaction to `D111` ("alice added a task: Txxx.") and an inverse transaction to `T222` ("alice added a revision: Dxxx").

Currently, it appears that the inverse transaction can sometimes generate mail faster than `D111` actually commits its (database) transactions, so the mail says "alice added a revision: Unknown Object (Differential Revision)". See T13082 for evidence that this is true, and a reproduction case.

To fix this, apply the inverse transaction (to `T222`) after we commit the main object (here, `D111`).

This is tricky because when we apply transactions, the transaction editor automatically "fixes" them to be consistent with the database state. For example, if a task already has title "XYZ" and you set the title to "XYZ" (same title), we just no-op the transaction.

It also fixes edge edits. The old sequence was:

  - Open (database) transaction.
  - Apply our transaction ("alice added a task").
  - Apply the inverse transaction ("alice added a revision").
  - Write the edges to the database.
  - Commit (database) transaction.

Under this sequence, the inverse transaction was "correct" and didn't need to be fixed, so the fixing step didn't touch it.

The new sequence is:

  - Open (database) transaction.
  - Apply our transaction ("alice added a task").
  - Write the edges.
  - Commit (database) transaction.
  - Apply the inverse transaction ("alice added a revision").

Since the inverse transaction now happens after the database edge write, the fixing step detects that it's a no-op and throws it away if we do this naively.

Instead, add some special cases around inverse edits to skip the correction/fixing logic, and just pass the "right" values in the first place.

Test Plan:
Added and removed related tasks from revisions, saw appropriate transactions render on both objects.

(It's hard to be certain this completely fixes the issue since it only happened occasionally in the first place, but we can see if it happens any more on `secure`.)

6bb31de305 Use the customizable "Welcome Mail" message in welcome mail
Summary:
Depends on D19994. See PHI1027. If an install has customized the "Welcome Mail" message, include it in welcome mail. A special custom message from the profile screen overrides it, if provided.

(I fiddled with putting the custom message as "placeholder" text in the remarkup area as a hint, but newlines in "placeholder" text appear to have issues in Safari and Firefox. I think this is probably reasonably clear as-is.)

Make both render remarkup-into-text so things like links work properly, as it's reasonably likely that installs will want to link to things.

Test Plan:
  - With custom "Welcome Mail" text, sent mail with no custom override (got custom text) and a custom override (got overridden text).
  - Linked to some stuff, got sensible links in the mail (`bin/mail show-outbound`).

2c713b2d25 Add "Auth Messages" to support customizing onboarding/welcome flows
Summary:
Ref T13222. Long ago, we had a Config option (`welcome.html`) to let you dump HTML onto the login screen, but this was relatively hard to use and not good from a security perspective.

In some cases this was obsoleted by Dashboards, but there's at least some remaining set of use cases for actual login instructions on the login screen. For example, WMF has some guidance on //which// SSO mechanism to use based on what types of account you have. On `secure`, users assume they can register by clicking "Log In With GitHub" or whatever, and it might reduce frustration to tell them upfront that registration is closed.

Some other types of auth messaging could also either use customization or defaults (e.g., the invite/welcome/approve mail).

We could do this with a bunch of Config options, but I'd generally like to move to a world where there's less stuff in Config and more configuration is contextual. I think it tends to be easier to use, and we get a lot of fringe benefits (granular permissions, API, normal transaction logs, more abililty to customize workflows and provide contextual help/hints, etc). Here, for example, we can provide a remarkup preview, which would be trickier with Config.

This does not actually do anything yet.

ab7aceaabf Allow administrators to provide custom welcome text when welcoming users on the profile workflow
Summary:
See PHI1027. Currently, we allow you to customize invite email, but not most other types of email (approve, welcome). As a step forward, also allow welcome email to be customized with a message.

I considered separating the custom text from the main text with something heavyhanded ("alice added this custom message:") or a beautiful ASCII art divider like one of these:

https://www.asciiart.eu/art-and-design/dividers

...but nothing truly sung to me.

This only works on the profile flow for now. I'm planning to let you set a default message. I may or may not let you customize from "Create New User", seems like the default message probably covers most of that. Probably won't touch `scripts/user/add_user.php` since that's not really exactly super supported.

Test Plan:
Sent mail with and without custom messages, reviewed it with `bin/mail show-outbound`.

5537e29ee8 Move "Welcome" mail generation out of PhabricatorUser
Summary:
Ref PHI1027. Currently, `PhabricatorUser` has a couple of mail-related methods which shouldn't really be there in the long term. Immediately, I want to make some adjusments to the welcome email.

Move "Welcome" mail generation to a separate class and consolidate all the error handling. (Eventually, "invite" and "verify address" email should move to similar subclasses, too.) Previously, a bunch of errors/conditions got checked in multiple places.

The only functional change is that we no longer allow you to send welcome mail to disabled users.

Test Plan:
  - Used "Send Welcome Mail" from profile pages to send mail.
  - Hit "not admin", "disabled user", "bot/mailing list" errors.
  - Used `scripts/user/add_user.php` to send welcome mail.
  - Used "Create New User" to send welcome mail.

310ad7f8f4 Put a hard limit on password login attempts from the same remote address
Summary:
Ref T13222. Currently, if a remote address fails a few login attempts (5) in a short period of time (15 minutes) we require a CAPTCHA for each additional attempt.

This relies on:

  - Administrators configuring ReCAPTCHA, which they may just not bother with.
  - Administrators being comfortable with Google running arbitrary trusted Javascript, which they may not be comfortable with.
  - ReCAPTCHA actually being effective, which seems likely true for unsophisticated attackers but perhaps less true for more sophisticated attackers (see <https://github.com/ecthros/uncaptcha2>, for example).

(For unsophisticated attackers and researchers, "Rumola" has been the standard CAPTCHA bypass tool for some time. This is an extension that pays humans to solve CAPTCHAs for you. This is not practical at "brute force a strong password" scale. Google appears to have removed it from the Chrome store. The "submit the captcha back to Google's APIs" trick probably isn't practical at brute-force-scale either, but it's easier to imagine weaponizing that than weaponizing human solvers.)

Add a hard gate behind the CAPTHCA wall so that we fail into a secure state if there's no CAPTCHA or the attacker can defeat CAPTCHAs at a very low cost.

The big downside to this is that an attacker who controls your remote address (e.g., is behind the same NAT device you're behind on corpnet) can lock you out of your account. However:

  - That //should// be a lot of access (although maybe this isn't that high of a barrier in many cases, since compromising a "smart fridge" or "smart water glass" or whatever might be good enough).
  - You can still do "Forgot password?" and login via email link, although this may not be obvious.

Test Plan:
  - Logged in normally.
  - Failed many many login attempts, got hard gated.

c125ab7a42 Remove "metamta.*.subject-prefix" options
Summary:
In ~2012, the first of these options was added because someone who hates dogs and works at Asana also hated `[Differential]` in the subject line. The use case there was actually //removing// the text, not changing it, but I made the prefix editable since it seemed like slightly less of a one-off.

These options are among the dumbest and most useless config options we have and very rarely used, see T11760. A very small number of instances have configured one of these options.

Newer applications stopped providing these options and no one has complained.

You can get the same effect with `translation.override`. Although I'm not sure we'll keep that around forever, it's a reasonable replacement today. I'll call out an example in the changelog to help installs that want to preserve this option.

If we did want to provide this, it should just be in {nav Applications > Settings} for each application, but I think it's wildly-low-value and "hack via translations" or "local patch" are entirely reasonable if you really want to change these strings.

Test Plan: Grepped for `subject-prefix`.

ff220acae6 Don't bounce mail messages if any recipient was reserved
Summary:
Ref T13222. If we receive a message and nothing processes it, we normally try to send the user an error message like "hey, nothing handled this, maybe you got the address wrong".

Just skip the "send them an error message" part if any recipient was reserved, so if you "Reply All" to a message that is "From: noreply@phabricator" you don't get a relatively unhelpful error.

This also makes sure that the "void" address doesn't generate bounces if the "From" is a valid user email address (e.g., with `metamta.can-send-as-user`). That is:

  - Phabricator needs to send a mail with only "CC" users.
  - Phabricator puts the "void" address in "To" as a placeholder.
  - The "void" address happens to route back to Phabricator.

We don't want that mail to bounce to anywhere. Normally, it won't:

  - From is usually "noreply@phabricator", which isn't a user, so we won't send anything back: we only send mail to verified user email addresses.
  - The message will have "X-Phabricator-Sent-This-Message: true" so we won't process it at all.

...but this is another layer of certainty.

Test Plan: Used `bin/mail receive-test` to receive mail to an invalid, unreserved address (bounce/error email) and an invalid, reserved address (no bounce/error email).

b5797ce60a Refactor mail to produce an intermediate "bag of strings" object in preparation for SMS
Summary:
Depends on D19954. Ref T920. This is a step toward a world where "Mailers" are generic and may send messages over a broader array of channels (email, SMS, postal mail).

There are a few major parts here:

  - Instead of calling `$mailer->setSubject()`, `$mailer->setFrom()`, etc., build in intermediate `$message` object first, then pass that to the mailer.
    - This breaks every mailer! This change on its own does not fix them. I plan to fix them in a series of "update mailer X", "update mailer Y" followups.
    - This generally makes the API easier to change in the far future, and in the near future supports mailers accepting different types of `$message` objects with the same API.
  - Pull the "build an email" stuff out into a `PhabricatorMailEmailEngine`. `MetaMTAMail` is already a huge object without also doing this translation step. This is just a separation/simplification change, but also tries to fight against `MetaMTAMail` getting 5K lines of email/sms/whatsapp/postal-mail code.
  - Try to rewrite the "build an email" stuff to be a bit more straightforward while making it generate objects. Prior to this change, it had this weird flow:

```lang=php
foreach ($properties as $key => $prop) {
  switch ($key) {
    case 'xyz':
      // ...
  }
}
```

This is just inherently somewhat hard to puzzle out, and it means that processing order depends on internal property order, which is quite surprising.

Test Plan: This breaks everything on its own; adapters must be updated to use the new API. See followups.

a37b28ef79 Prevent inbound processing of the "void/placeholder" address and other reserved addresses
Summary:
Depends on D19952. Ref T13222. Never process mail targets if they match:

  - The "default" address which we send mail "From".
  - The "void" address which we use as a placholder "To" when we only have "CC" addresses.
  - Any address from a list of reserved/administrative names.

The first two prevent loops. The third one prevents abuse.

There's a reasonably well-annotated list of reservations and reasons here:

https://webmasters.stackexchange.com/questions/104811/is-there-any-list-of-email-addresses-reserved-because-of-security-concerns-for-a

Stuff like `support@` seems fine; stuff like `ssladmin@` might let you get SSL certs issued for a domain you don't control.

Also, forbid users from creating application emails with these reserved addresses.

Finally, build the default and void addresses somewhat more cleverly.

Test Plan: Added unit tests, tried to configured reserved addresses, hit the default/void cases manually with `bin/mail receive-test`.

e3aa043a02 Allow multiple mail receivers to react to an individual email
Summary:
Fixes T7477. Fixes T13066. Currently, inbound mail is processed by the first receiver that matches any "To:" address. "Cc" addresses are ignored.

**To, CC, and Multiple Receivers**

Some users would like to be able to "Cc" addresses like `bugs@` instead of having to "To" the address, which makes perfect sense. That's the driving use case behind T7477.

Since users can To/Cc multiple "create object" or "update object" addresses, I also wanted to make the behavior more general. For example, if you email `bugs@` and also `paste@`, your mail might reasonably make both a Task and a Paste. Is this useful? I'm not sure. But it seems like it's pretty clearly the best match for user intent, and the least-surprising behavior we can have. There's also no good rule for picking which address "wins" when two or more match -- we ended up with "address order", which is pretty arbitrary since "To" and "Cc" are not really ordered fields.

One part of this change is removing `phabricator.allow-email-users`. In practice, this option only controlled whether users were allowed to send mail to "Application Email" addresses with a configured default author, and it's unlikely that we'll expand it since I think the future of external/grey users is Nuance, not richer interaction with Maniphest/Differential/etc. Since this option only made "Default Author" work and "Default Author" is optional, we can simplify behavior by making the rule work like this:

  - If an address specifies a default author, it allows public email.
  - If an address does not, it doesn't.

That's basically how it worked already, except that you could intentionally "break" the behavior by not configuring `phabricator.allow-email-users`. This is a backwards compatility change with possible security implications (it might allow email in that was previously blocked by configuration) that I'll call out in the changelog, but I suspect that no installs are really impacted and this new behavior is generally more intuitive.

A somewhat related change here is that each receiver is allowed to react to each individual email address, instead of firing once. This allows you to configure `bugs-a@` and `bugs-b@` and CC them both and get two tasks. Useful? Maybe not, but seems like the best execution of intent.

**Sender vs Author**

Adjacently, T13066 described an improvement to error handling behavior here: we did not distinguish between "sender" (the user matching the email "From" address) and "actor" (the user we're actually acting as in the application). These are different when you're some internet rando and send to `bugs@`, which has a default author. Then the "sender" is `null` and the "author" is `@bugs-robot` or whatever (some user account you've configured).

This refines "Sender" vs "Author". This is mostly a purity/correctness change, but it means that we won't send random email error messages to `@bugs-robot`.

Since receivers are now allowed to process mail with no "sender" if they have some default "actor" they would rather use instead, it's not an error to send from an invalid address unless nothing processes the mail.

**Other**

This removes the "abundant receivers" error since this is no longer an error.

This always sets "external user" mail recipients to be unverified. As far as I can tell, there's no pathway by which we send them email anyway (before or after this change), although it's possible I'm missing something somewhere.

Test Plan:
I did most of this with `bin/mail receive-test`. I rigged the workflow slightly for some of it since it doesn't support multiple addresses or explicit "CC" and adding either would be a bit tricky.

These could also be tested with `scripts/mail/mail_handler.php`, but I don't currently have the MIME parser extension installed locally after a recent upgrade to Mojave and suspect T13232 makes it tricky to install.

- Ran unit tests, which provide significant coverage of this flow.
- Sent mail to multiple Maniphest application emails, got multiple tasks.
- Sent mail to a Maniphest and a Paste application email, got a task and a paste.
- Sent mail to a task.
  - Saw original email recorded on tasks. This is a behavior particular to tasks.
- Sent mail to a paste.
- Sent mail to a mock.
- Sent mail to a Phame blog post.
- Sent mail to a Legalpad document.
- Sent mail to a Conpherence thread.
- Sent mail to a poll.
- This isn't every type of supported object but it's enough of them that I'm pretty confident I didn't break the whole flow.
- Sent mail to an object I could not view (got an error).
- As a non-user, sent mail to several "create an object..." addresses.
  - Addresses with a default user worked (e.g., created a task).
  - Addresses without a default user did not work.

73e3057c52 Rename "MetaMTA" mail attachments and add more mail message objects
Summary:
Depends on D19953. Ref T9141. We have a "MetaMTAAttachment" object, rename it to "MailAttachment".

Also add a "Header" object and an "EmailMessage" object. Currently, mail adapters have a large number of methods like `setSubject()`, `addTo()`, etc, that I would like to remove.

I'd like the API to be more like `sendMessage(PhabricatorMailExternalMessage $message)`. This is likely a significant simplification anyway, since the implementations of all these methods are just copy/pasted boilerplate anyway (lots of `$this->subject = $subject;`) and this will let Adapters support other message media (SMS, APNS, Whatsapp, etc.)

That's a larger change, but move toward a world where we can build a concrete `$message` object for "email" or "sms".

The `PhabricatorMailEmailMessage` object is just a dumb, flat object representation of the information an adapter needs to actually send mail. The existing `PhabricatorMetaMTAMail` is a much more complex object and has a lot of rich data (delivery status, related object PHIDs, etc) and is a storage object.

The new flow will be something like:

  - `PhabricatorMetaMTAMail` (possibly renamed) is the storage object for any outbound message on this channel. It tracks message content, acceptable delivery media (SMS vs email), delivery status, related objects, has a PHID, and has a daemon worker associated with delivering it.
  - It builds a `PhabricatorMailExternalMessage`, which is a simple, flat description of the message it wants to send. The subclass of this object depends on the message medium. For email, this will be an `EmailMessage`. This is just a "bag of strings" sort of object, with appropriate flattened values for the adapter to work with (e.g., Email has email addresses, SMS has phone numbers).
  - It passes the `ExternalMessage` (which is a `MailMessage` or `SMSMessage` or whatever) to the adapter.
  - The adapter reads the nice flat properties off it and turns them into an API request, SMTP call, etc.

This is sort of how things work today anyway. The major change is that I want to hand off a "bag of strings" object instead of calling `setX()`, `setY()`, `setZ()` with each individual value.

Test Plan: Grepped for `MetaMTAAttachment`. This doesn't change any behavior yet.

84f94994ad Remove "metamta.insecure-auth-with-reply-to" Config option
Summary:
Ref T7477. This option was added in D842 in 2011, to support a specific narrow use case at Quora with community moderators using some kind of weird Gmail config.

I don't recall it ever coming up since then, and a survey of a subset of hosted instances (see T11760) reveals that no instances are using this option today. Presumably, even Quora has completed the onboarding discussed in D842, if they still use Phabricator. This option generally does not seem very useful outside of very unusual/narrow cases like the one Quora had.

This would be relatively easy to restore as a local patch if installs //do// need it, but I suspect this has no use cases anywhere.

e2f0571104 Drop empty inbound mail at the beginning of the receive workflow, not inside object handlers
Summary:
Ref T920. Ref T7477. We currently drop empty mail only once it reaches the `ReplyHandler` layer.

I think no plausible receiver can ever do anything useful with this kind of mail, so we can safely drop it earlier and simplify some of the logic. After T7477, we'd end up throwing multiple exceptions if you sent empty mail to several valid receivers.

(I also want to move away from APIs oriented around raw addresses in more specialized layers, and this is one of the few callsites for raw mail address information.)

This requires updating some unit tests to actually have message bodies, since they failed with this error before hitting the other errors otherwise.

1f4cf23455 Remove "phabricator.csrf-key" and upgrade CSRF hashing to SHA256
Summary:
Ref T12509.

  - Remove the "phabricator.csrf-key" configuration option in favor of automatically generating an HMAC key.
  - Upgrade two hasher callsites (one in CSRF itself, one in providing a CSRF secret for logged-out users) to SHA256.
  - Extract the CSRF logic from `PhabricatorUser` to a standalone engine.

I was originally going to do this as two changes (extract logic, then upgrade hashes) but the logic had a couple of very silly pieces to it that made faithful extraction a little silly.

For example, it computed `time_block = (epoch + (offset * cycle_frequency)) / cycle_frequency` instead of `time_block = (epoch / cycle_frequency) + offset`. These are equivalent but the former was kind of silly.

It also computed `substr(hmac(substr(hmac(secret)).salt))` instead of `substr(hmac(secret.salt))`. These have the same overall effect but the former is, again, kind of silly (and a little bit materially worse, in this case).

This will cause a one-time compatibility break: pages loaded before the upgrade won't be able to submit contained forms after the upgrade, unless they're open for long enough for the Javascript to refresh the CSRF token (an hour, I think?). I'll note this in the changelog.

Test Plan:
  - As a logged-in user, submitted forms normally (worked).
  - As a logged-in user, submitted forms with a bad CSRF value (error, as expected).
  - As a logged-out user, hit the success and error cases.
  - Visually inspected tokens for correct format.

Summary:
Ref T920. This simplifies mail configuration.

The "metamta.domain" option is only used to generate Thread-ID values, and we just need something that looks like a bit like a domain in order to make GMail happy. Just use the install domain. In most cases, this is almost certainly the configured value anyway. In some cases, this may cause a one-time threading break for existing threads; I'll call this out in the changelog.

The "metamta.placeholder-to-recipient" is used to put some null value in "To:" when a mail only has CCs. This is so that if you write a local client mail rule like "when I'm in CC, burn the message in a fire" it works even if all the "to" addresses have elected not to receive the mail. Instead: just send it to an unlikely address at our own domain.

I'll add some additional handling for the possiblity that we may receive this email ourselves in the next change, but it overlaps with T7477.

afa69eedd1 Remove an old digest in Celerity code and some obsolete configuration options
Summary:
Ref T12509. This upgrades a `weakDigest()` callsite to SHA256-HMAC and removes three config options:

  - `celerity.resource-hash`: Now hard-coded, since the use case for ever adjusting it was very weak.
  - `celerity.enable-deflate`: Intended to make cache inspection easier, but we haven't needed to inspect caches in ~forever.
  - `celerity.minify`: Intended to make debugging minification easier, but we haven't needed to debug this in ~forever.

In the latter two cases, the options were purely developer-focused, and it's easy to go add an `&& false` somewhere in the code if we need to disable these features to debug something, but the relevant parts of the code basically work properly and never need debugging. These options were excessively paranoid, based on the static resource enviroment at Facebook being far more perilous.

The first case theoretically had end-user utility for fixing stuck content caches. In modern Phabricator, it's not intuitive that you'd go adjust a Config option to fix this. I don't recall any users ever actually running into problems here, though.

(An earlier version of this change did more magic with `celerity.resource-hash`, but this ended up with a more substantial simplification.)
