Onebox improved error handling and support for Instagram Access Tokens (#11253)
* FEATURE: display error if Oneboxing fails due to HTTP error

- display warning if onebox URL is unresolvable
- display warning if attributes are missing

* FEATURE: Use new Instagram oEmbed endpoint if access token is configured

Instagram requires an Access Token to access their oEmbed endpoint. The requirements (from https://developers.facebook.com/docs/instagram/oembed/) are as follows:

- a Facebook Developer account, which you can create at developers.facebook.com
- a registered Facebook app
- the oEmbed Product added to the app
- an Access Token
- The Facebook app must be in Live Mode

The generated Access Token, once added to SiteSetting.facebook_app_access_token, will be passed to onebox. Onebox can then use this token to access the oEmbed endpoint to generate a onebox for Instagram.

* DEV: update user agent string

* DEV: don’t do HEAD requests against news.yahoo.com

* DEV: Bump onebox version from 2.1.5 to 2.1.6

* DEV: Avoid re-reading templates

* DEV: Tweaks to onebox mustache templates

* DEV: simplified error message for missing onebox data

* Apply suggestions from code review

FIX: Replace deprecated URI.encode, URI.escape, URI.unescape and URI.unencode (#8528)
The following methods have long been deprecated in ruby due to flaws in their implementation per http://blade.nagaokaut.ac.jp/cgi-bin/vframe.rb/ruby/ruby-core/29293?29179-31097:

URI.escape
URI.unescape
URI.encode
URI.unencode
escape/encode are just aliases for one another. This PR uses the Addressable gem to replace these methods with its own encode, unencode, and encode_component methods where appropriate.

I have put all references to Addressable::URI here into the UrlHelper to keep them corralled in one place to make changes to this implementation easier.

Addressable is now also an explicit gem dependency.

Sam Saffron 7429700389 FIX: ensure we can download maxmind without redis or db config
This also corrects FileHelper.download so it supports "follow_redirect"
correctly (it used to always follow 1 redirect) and adds a `validate_url`
param that will bypass all uri validation if set to false (default is true)

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

this ensures we always bypass and do not read entire payloads

Guo Xiang Tan d43895e2a0 Don't log 404s for `FinalDestination`.
* We can't do anything about 404s
2018-05-25 10:11:16 +08:00
Guo Xiang Tan 142571bba0 Remove use of `rescue nil`.
* `rescue nil` is a really bad pattern to use in our code base.
  We should rescue errors that we expect the code to throw and
  not rescue everything because we're unsure of what errors the
  code would throw. This would reduce the amount of pain we face
  when debugging why something isn't working as expexted. I've
  been bitten countless of times by errors being swallowed as a
  result during debugging sessions.

Sam Saffron 8185b8cb06 FEATURE: cache https redirects per hostname
If a hostname does an https redirect we cache that so next
lookup does not incur it.

Also, only rate limit per ip once per final destination

Raise final destination protection to 1000 ip lookups an hour

Sam 70bb2aa426 FEATURE: allow specifying s3 config via globals
This refactors handling of s3 so it can be specified via GlobalSetting

This means that in a multisite environment you can configure s3 uploads
without actual sites knowing credentials in s3

It is a critical setting for situations where assets are mirrored to s3.
