Summary:
- We have a hard-coded minimum length of 3 right now (and 1 in the other
interface), which is sort of silly.
- Provide a more reasonable default, and allow it to be configured.
- We have two password reset interfaces, one of which no longer actually
requires you to verify you own the account. This is more than a bit derp.
- Merge the interfaces into one, using either an email token or the account's
current password to let you change the password.
Test Plan:
- Reset password on an account.
- Changed password on an account.
- Created a new account, logged in, set the password.
- Tried to set a too-short password, got an error.

Summary:
If you try to establish several sessions quickly (e.g., by running several
copies of "arc" at once, as in "arc x | arc y"), the current logic has a high
chance of making them all pick the same conduit session to refresh (since it's
the oldest one when each process selects the current sessions). This means they
all issue updates against "conduit-3" (or whatever) and one ends up with a bogus
session.
Instead, do an update against the table with the session key we read, so only
one process wins the race. If we don't win the race, try again until we do or
have tried every session slot.
Test Plan:
- Wiped conduit sessions, ran arc commands to verify the fresh session case.
- Ran a bunch of arc piped to itself, e.g. "arc list | arc list | arc list |
...". It succeeds up to the session limit, and above that gets failures as
expected.
- Manually checked the session table to make sure things seemed reasonable
there.
- Generally ran a bunch of arc commands.
- Logged out and logged in on the web interface.

moves us off raw sha1() calls in order to make it easier to audit the codebase

- We now generate HMAC mail keys but accept MAC or HMAC. In a few months, we
can remove the MAC version.
- The only remaining callsite is Conduit. We can't use HMAC since Arcanist
would need to know the key. {T550} provides a better solution to this, anyway.

This is pretty straightforward, except:
- We need to request read/write access to the address book to get the account
ID (which we MUST have) and real name, email and account name (which we'd like

"get_loggedin_user_basic_information" type of call in the Google API suite (or,
at least, I couldn't find one).
- We can't get the profile picture or profile URI since there's no Plus API
access and Google users don't have meaningful public pages otherwise.
- Google doesn't save the fact that you've authorized the app, so every time
you want to login you need to reaffirm that you want to give us silly amounts of
access. Phabricator sessions are pretty long-duration though so this shouldn't
be a major issue.

- Since we have a small number of storage mechanisms and highly structured

performing a write?".
- Never allow writes without CSRF checks.
- This will probably break some things. That's fine: they're CSRF
vulnerabilities or weird edge cases that we can fix. But don't push to Facebook
for a few days unless you're prepared to deal with this.

Summary:
We currently cycle CSRF tokens every hour and check for the last two valid ones.
This means that a form could go stale in as little as an hour, and is certainly
stale after two.
When a stale form is submitted, you basically get a terrible heisen-state where
some of your data might persist if you're lucky but more likely it all just
vanishes. The .js file below outlines some more details.
This is a pretty terrible UX and we don't need to be as conservative about CSRF
validation as we're being. Remedy this problem by:
- Accepting the last 6 CSRF tokens instead of the last 1 (i.e., pages are
valid for at least 6 hours, and for as long as 7).
- Using JS to refresh the CSRF token every 55 minutes (i.e., pages connected
to the internet are valid indefinitely).
- Showing the user an explicit message about what went wrong when CSRF
validation fails so the experience is less bewildering.
They should now only be able to submit with a bad CSRF token if:
- They load a page, disconnect from the internet for 7 hours, reconnect, and
submit the form within 55 minutes; or
- They are actually the victim of a CSRF attack.
We could eventually fix the first one by tracking reconnects, which might be
"free" once the notification server gets built. It will probably never be an
issue in practice.
Test Plan:
- Reduced CSRF cycle frequency to 2 seconds, submitted a form after 15
seconds, got the CSRF exception.
- Reduced csrf-refresh cycle frequency to 3 seconds, submitted a form after 15
seconds, got a clean form post.
- Added debugging code the the csrf refresh to make sure it was doing sensible
things (pulling different tokens, finding all the inputs).

Summary:
Currently, we echo the password as the user types it. This turns out to be a bit
of an issue in over-the-shoulder installs. Instead, disable tty echo while the
user is typing their password so nothing is shown (like how 'sudo' works).
Also show a better error message if the user chooses a duplicate email; without
testing for this we just throw a duplicate key exception when saving, which
isn't easy to understand. The other duplicate key exception is duplicate
username, which is impossible (the script updates rather than creating in this
case).
There's currently a bug where creating a user and setting their password at the
same time doesn't work. This is because we hash the PHID into the password hash,
but it's empty if the user hasn't been persisted yet. Make sure the user is
persisted before setting their password.
Finally, fix an issue where $original would have the new username set, creating
a somewhat confusing summary at the end.
I'm also going to improve the password behavior/explanation here once I add
welcome emails ("Hi Joe, epriestley created an account for you on Phabricator,
click here to login...").

- Typed a password and didn't have it echoed. I also tested this on Ubuntu
