Summary:
The "Export Data" workflow incorrectly uses the "Policy Favorites" setting to choose a default export format. This is just a copy/paste error; the correct setting exists and is unused.
If the setting value is an array (as the "Policy Favorites" value often is), we try to use it as an array index. This generates a runtime exception after D21044.

Summary:
See <https://discourse.phabricator-community.org/t/bad-regex-in-prose-diff-logic/3969>.
The prose splitting rules normally guarantee that newlines appear only at the beginning or end of blocks. However, if a prose sentence ends with text like "...x\n.", we can end up with a newline inside a "sentence".
If we do, the regular expression that breaks it into pieces will fail.
Arguably, this is an error in how sentences are split apart (we might prefer to split this into two sentences, "x\n" and ".", rather than a single "x\n." sentence) but in the general case it's not unreasonable for blocks to contain newlines, so a simple fix is to make the pattern more robust.
Test Plan: Added a failing test which includes this behavior, made it pass.

Summary:
Currently, Phortune attempts to prevent users from removing themselves as account managers. It does this by checking that the new list includes them.
Usually this is sufficient, because you can't normally edit an account unless you're already a manager. However, we get the wrong result (incorrect rejection of the edit) if the actor is omnipotent and the acting user was not already a member.
It's okay to edit an account into a state which doesn't include you if you have permission to edit the account and aren't already a manager.
Specifically, this supports more formal tooling around staff modifications to billing accounts, where the actor has staff-omnipotence and the acting user is a staff member and only used for purposes of leaving a useful audit trail.
Test Plan: Elsewhere, ran staff tooling to modify accounts and was able to act as "alice" to add "bailey", even though "alice" was not herself a manager.

Summary:
See <https://discourse.phabricator-community.org/t/how-to-override-localhost-localdomain-in-email-message-id/3876/>.
Currently, Phabricator generates a "Message-ID" only in a subset of cases (roughly: when the message is first-in-thread and we expect the thread may have more than one message).
In cases where it does not generate a message ID, it expects the SMTP server to generate one for it. Servers will generally do this, and some ONLY do this (that is, they ignore IDs from Phabricator and replace them). Thus, several pieces of configuration control whether Phabricator attempts to generate a "Message-ID" at all.
The PHPMailer code has fallback behavior which generates a "<random>@localhost.localdomain" message ID. This is never desirable and ignores Phabricator-level configuration that Message IDs should not be generated.
For now, remove this code: it is never the desired behavior and sometimes explicitly contradicts the intent of configuration.
Possibly, a better change may be to make Phabricator always generate a message ID in cases where it isn't forbidden from doing so by configuration. However, that's a more complicated change and it's not clear if/when it would produce better behavior, so start here for now.
Test Plan: Confirmed by affected user (see linked thread).

This algorithm currently counts "\ No newline at end of file" lines as though they were normal source lines. This can cause offset issues in the rare case that a diff contains two of these lines (for each side of the file) and has changes between them (because the last line of the file was modified between the diffs).

Summary:
Ref T13538. See PHI1739. Synthetic Git commits with no author and/or no commit message currently extract `null` and then fail to parse.
Ideally, we would carefully distinguish between `null` and empty string. In practice, that requires significant schema changes (these columns are non-nullable and have indexing requirements) and these cases are degenerate. These commits are challenging to build and can not normally be constructed with `git commit`.
At least for now, merge the `null` cases into the empty string cases so we can survive import.
Test Plan:
- Constructed a commit with no author and no commit message using the approach described in T13538; pushed and parsed it.
- Before: fatals during identity selection and storing the commit message (both roughly NULL inserts into non-null columns).
- After: clean import.

Summary:
Ref T13529. Now that instances can be renamed, an instance may have multiple valid SSH usernames and the preferred SSH username may not be the intenal instance name.
`PhacilitySiteSource` should already always set `diffusion.ssh-username` correctly, to the current preferred SSH username (which may be "new-name" after a rename from "old-name"), so we should never be able to reach this code without an accurate `diffusion.ssh-username` value available.
The code to resolve names into instances also already works for both "ssh old-name@..." and "ssh new-name@...".
So I believe this code has no beneficial effects and only causes harm: it may force us to return "old-name" when falling through would correctly return "new-name".
Test Plan:
- Previously: renamed an instance, then SSH'd to it using both the old and new names. Both work.
- Previously: verified that `diffusion.ssh-username` is set correctly after a rename.
- Verified that Diffusion "Clone" UI now shows "new-name" after an instance rename.

- view a 2-up diff with content on both sides;

- use your mouse to click "New Inline Comment" in the context menu that pops up.
The mousedown event for the "New Inline Comment" click removes the "copy selection" behavior and creates a flash where both sides of the diff are selected.
This doesn't happen with (most) normal clicks because mouse down on a non-grabbable element clears the document selection.
To avoid this, don't reset the copy selection behavior if the user mouses down on an "<a />". This might not be robust, but seems simple and plausible as a fix.

After changes to distinguish between invalid and passphrase-protected keys, SSH private key management code incorrectly uses "-y ..." ("print public key") when it means "-p ..." ("modify input file, removing passphrase"). This results in the command having no effect, and Passphrase stores the raw input credential, not the stripped version.
We can't recover the keys because we don't store the passphrase, so no migration here is really possible. (We could add more code to detect this case, but it's presumably rare.)
