Tighten the Phabricator support policy from "we will help with literally anything for free" to "we will help with anything for free, except unreproducible fishing expeditions".
This is not the right policy in the long term (in some form, I expect the level of free support will decrease, and, e.g., I won't be offering to drive to your place and fix your stuff), but this class of issue is by far the worst and most pressing and I want to stop dealing with fishing expeditions like this one right now, since I hate supporting them and they're a disproportionately huge waste of time:

- The most common workflow complaint I've seen recently is something like "how do I use Differential with a branch full of random code that me and several other developers all commit to"? There are some okay answers ("commandeer") but I think the best answer is "don't do that". Add a document explaining how development works at Facebook (and many other companies) without the use of feature branching, why it's better, and how you can lay the technical groundwork you need to to stop doing this.
- Add a general "smaller commits are better" and "your commit messsage should provide context" document.

Long term we'll probably delete timeline and move to webhooks, since everyone who has asked about this stuff has been eager to trade away the durability and ordering of the timeline for the ease of use of webhooks. There's also no reason to timeline this anymore since parsing is no longer order-dependent.

lighttpd could support rules like this, to add efficiency:
# Aggressively cache all static files
$HTTP["url"] =~ "\.(jpg|gif|png|css|js|htc)" {
expire.url = ( "" => "access 1 years" )
}
# Compress files for faster transfer
compress.filetype = (
"text/plain",
"text/html",
"text/javascript",
"text/css",
"text/xml"
)
compress.cache-dir = <would need to set to something>?
I don't know if that is necessary or useful. Probably not a good idea
at this point, where the code is changing so rapidly: a 1 year cache
of javascript code could cause trouble. And i think the default
lighttpd.conf already compresses text/html, text/plain, text/css, and
application/x-javascript by default, so we're ok there (could add
text/javascript and text/xml, I guess).
Summary:
This addresses three issues with the current patch management system:
# Two people developing at the same time often pick the same SQL patch number, and then have to go rename it. The system catches this, but it's silly.
# Second/third-party developers can't use the same system to manage auxiliary storage they may want to add.
# There's no way to build mock databases for unit tests that need to do reads.
To resolve these things, you can now name your patches whatever you want and conflicts are just merge conflicts, which are less of a pain to fix than filename conflicts.
Dependencies are now a DAG, with implicit dependencies created on the prior patch if no dependencies are specified. Developers can add new concrete subclasses of `PhabricatorSQLPatchList` to add storage management, and define the dependency branchpoint of their patches so they apply in the correct order (although, generally, they should not depend on the mainline patches, presumably).
The commands `storage upgrade --namespace test1234` and `storage destroy --namespace test1234` will allow unit tests to build and destroy MySQL storage.
A "quickstart" mode allows an upgrade from scratch in ~1200ms. Destruction takes about 200ms. These seem like fairily reasonable costs to actually use in tests. Building from scratch patch-by-patch takes about 6000ms.
Test Plan:
- Created new databases from scratch with and without quickstart in a separate test namespace. Pointed the webapp at the test namespaces, browsed around, everything looked good.
- Compared quickstart and no-quickstart dump states, they're identical except for mysqldump timestamps and a few similar things.
- Upgraded a legacy database to the new storage format.
- Destroyed / dumped storage.

Summary:
We have a lot of cases where we store object relationships, but it's all kind of messy and custom. Some particular problems:
- We go to great lengths to enforce order stability in Differential revisions, but the implementation is complex and inelegant.
- Some relationships are stored on-object, so we can't pull the inverses easily. For example, Maniphest shows child tasks but not parent tasks.
- I want to add more of these and don't want to continue building custom stuff.
- UIs like the "attach stuff to other stuff" UI need custom branches for each object type.
- Stuff like "allow commits to close tasks" is notrivial because of nonstandard metadata storage.
Provide an association-like "edge" framework to fix these problems. This is nearly identical to associations, with a few differences:
- I put edge metadata in a separate table and don't load it by default, to keep edge rows small and allow large metadata if necessary. The on-edge metadata seemed to get abused a lot at Facebook.
- I put a 'seq' column on the edges to ensure they have an explicit, stable ordering within a source and type.
This isn't actually used anywhere yet, but my first target is attaching commits to tasks for T904.
Test Plan: Made a mock page that used Editor and Query. Verified adding and removing edges, overwriting edges, writing and loading edge data, sequence number generation.
