Summary:
Ref T11589. Previously, when we failed to load database configuration we just continued anyway, in order to get to setup checks so we could raise a better error.
There was a small chance that this could lead to pages running in a broken state, where ONLY that connection failed and everything else worked. This was accidentally fixed by narrowing the exceptions we continue on in D16489.
However, this "fix" meant that users no longer got helpful setup instructions. Instead:
- Keep throwing these exceptions: it's bad to continue if we've failed to connect to the database.
- However, catch them and turn them into setup errors.
- Share all the setup code so these errors and setup check errors work the same way.
Test Plan:
- Intentionally broke `mysql.host` and `mysql.pass`.
- Loaded pages.
- Got good setup errors.
- Hit normal setup errors too.
- Put everything back.
- Swapped into cluster mode.
- Intentionally broke cluster mode, saw failover to readonly.

- preflight checks (critical checks: PHP version stuff, extensions);
- configuration;
- normal checks.
The PHP checks are split into critical ("bad version") and noncritical ("sub-optimal config").
I tidied up the extension checks slightly, we realistically depend on `cURL` nowadays.

- Loaded normal pages.

- Used DarkConsole "Startup" tab to verify that preflight checks take <1ms to run (we run them on every page without caching, at least for now, but they only do trivial checks like PHP versions).

Fixes T11480. This cleans up the error logs a little by quieting three common errors which are really malformed requests:
- The CSRF error happens when bots hit anything which does write checks.
- The "wrong cookie domain" errors happen when bots try to use the `security.alternate-file-domain` to browse stuff like `/auth/start/`.
- The "no phcid" errors happen when bots try to go through the login flow.
All of these are clearly communicated to human users, commonly encountered by bots, and not useful to log.
I collapsed the `CSRFException` type into a standard malformed request exception, since nothing catches it and I can't really come up with a reason why anything would ever care.
Test Plan:
Hit each error through some level of `curl -H ...` and/or fakery. Verified that they showed to users before/after, but no longer log.

This either generates the preview or redirects to an existing preview. This is a good behavior in general, because the preview may take a while to generate and we don't want to wait for it to generate on the server side.
However, this flickers a lot in Safari. We might be able to cache this, but we really shouldn't, since the preview URI isn't a legitimately stable/permanent one.
Instead, do a (cheap) server-side check to see if the preview already exists. If it does, return a direct URI. This gives us a stable thumbnail in Safari.

The URI will stop working once any attached object changes its view policy, or the file view policy itself changes.
Files with `canCDN` (totally public data like profile images, CSS, JS, etc) use "cache-control: public" so they can be CDN'd.
Files without `canCDN` use "cache-control: private" so they won't be cached by the CDN. They could still be cached by a misbehaving local cache, but if you don't want your users seeing one anothers' secret files you should configure your local network properly.
Our "Cache-Control" headers were also from 1999 or something, update them to be more modern/sane. I can't find any evidence that any browser has done the wrong thing with this simpler ruleset in the last ~10 years.

This is a likely fix for HTTP clones against proxied repositories in the
cluster, although I'm not 100% sure I'm replicating it correctly.
The issue appears to be that we're proxying all the headers, including the
"Transfer-Encoding" header, although the request will already have stripped
any encoding. This might cause us to emit a "chunked" header without a
chunked body.
Auditors: chad
When you `getInt()` an array, PHP decides the array has value `1`. This would
cause us to post to blog #1 incorrectly. I didn't catch this locally because
I happened to be posting to blog #1.
Stop us from interpreting array values as `1`, and fix blog interpretation.
This approach is a little messy (projects has the same issue) but I'll see
if I can clean it up in some future change.

Summary:
Ref T10004. After a user logs in, we send them to the "next" URI cookie if there is one, but currently don't always do a very good job of selecting a "next" URI, especially if they tried to do something with a dialog before being asked to log in.
In particular, if a logged-out user clicks an action like "Edit Blocking Tasks" on a Maniphest task, the default behavior is to send them to the standalone page for that dialog after they log in. This can be pretty confusing.
See T2691 and D6416 for earlier efforts here. At that time, we added a mechanism to //manually// override the default behavior, and fixed the most common links. This worked, but I'd like to fix the //default// beahvior so we don't need to remember to `setObjectURI()` correctly all over the place.
ApplicationEditor has also introduced new cases which are more difficult to get right. While we could get them right by using the override and being careful about things, this also motivates fixing the default behavior.
Finally, we have better tools for fixing the default behavior now than we did in 2013.
Instead of using manual overrides, have JS include an "X-Phabricator-Via" header in Ajax requests. This is basically like a referrer header, and will contain the page the user's browser is on.
In essentially every case, this should be a very good place (and often the best place) to send them after login. For all pages currently using `setObjectURI()`, it should produce the same behavior by default.
I'll remove the `setObjectURI()` mechanism in the next diff.
Test Plan: Clicked various workflow actions while logged out, saw "next" get set to a reasonable value, was redirected to a sensible, non-confusing page after login (the page with whatever button I clicked on it).

- Merge "publish" and "unpublish" controllers into one.
New behavior:
- Blogs and posts have three views:
- "View": Internal view URI, which is a normal detail page.
- "Internal Live": Internal view URI which is a little prettier.
- "External Live": External view URI for an external domain.
Right now, the differences are pretty minor (basically, different crumbs/chrome). This mostly gives us room to put some milder flavor of skins back later (photography or more "presentation" elements, for example).
This removes 9 million lines of code so I probably missed a couple of things, but I think it's like 95% of the way there.
Test Plan:
Here are some examples of what the "view", "internal" and "external" views look like for blogs (posts are similar):
"View": Unchanged
{F1021634}
"Internal": No chrome or footer. Still write actions (edit, post commments). Has crumbs to get back into Phame.
{F1021635}
"External": No chrome or footer. No write actions. No Phabricator crumbs. No policy/status information.
{F1021638}
I figure we'll probably tweak these a bit to figure out what makes sense (like: maybe no actions on "internal, live"? and "external, live" probably needs a way to set a root "Company >" crumb?) but that they're reasonable-ish as a first cut?

Right now it lives in some odd places. Notably, `PhabricatorApplicationSearchEngine` has some weird helper methods for this stuff. Rather than give `EditEngine` the same set of weird helper methods, pull all this stuff out into "HTTPParameterTypes".
Future diffs will add "Projects" and "Users" types where all the custom parsing/lookup logic can live. Then eventually the Search stuff can reuse these.

Two possible approaches are:
# Prevent the write from occuring.
# Change the code to allow the write.
In the past, I think we've hit similar cases and done (1). However, IIRC those writes were sketchier, more isolated, and easy to remove (I think there was one with PKCS8 keys). This one is pretty legit and not very easy to remove without making a bit of a mess.
There's no techncial reason we can't do (2), we just have to create a no-op WriteGuard for the setup phase.
