2018-03-26Validate HTTP response length while receiving (#6891)Akihiko Odaki
to_s method of HTTP::Response keeps blocking while it receives the whole content, no matter how it is big. This means it may waste time to receive unacceptably large files. It may also consume memory and disk in the process. This solves the inefficency by checking response length while receiving.
2018-03-24Close http connection in perform method of Request class (#6889)Akihiko Odaki
HTTP connections must be explicitly closed in many cases, and letting perform method close connections makes its callers less redundant and prevent them from forgetting to close connections.

2018-02-02Fix saving of oEmbed image (#6409)abcang

2017-12-07Add embed_url to preview cards (#5775)Akihiko Odaki
2017-11-20Fixed duplicating URL of photo type of oEmbed (#5763)abcang
2017-10-17Don't capture scheme-less URLs in the status (#5435)unarist
Specifically, this fixes status length calculation to be same as JS side. BTW, since this pattern used in not only preview card fetching, we should extract it (with twitter-regex?) and write tests I think.
2017-10-12Fix some failure cases on FetchLinkCardService (#5347)unarist
* If OEmbed response doesn't have a required property `type`, ignore it. e.g. `NoMethodError: undefined method 'type' for ...` * If we failed to detect encoding, fallback to default behavior of Nokogiri. e.g. `KeyError: key not found: :encoding`
2017-10-06Improve error handling on LinkCrawlWorker (#5250)unarist
* Improve error handling on LinkCrawlWorker * Ignore TimeoutError and InvalidURIError too * Record errors to debug log * Enable dead job queue on LinkCrawlWorker Since most of acceptable errors were already ignored, only our side issue should go to dead job queue. * Ignore all http gem errors
2017-09-14Enable to recognize most kinds of characters as URL paths (#4941)ふぁぼ原
2017-09-14Support OpenGraph video embeds (#4897)Eugen Rochko
* Support OpenGraph video embeds It's not really OpenGraph, it's twitter:player property, but it's not OEmbed so that fits. For example, this allows Twitch clips to be displayed as embeds. Also, fixes glitch-soc/mastodon#135 * Fix invalid OpenGraph cards being saved through attaching and revisit URLs after 14 days
2017-09-01Make PreviewCard records reuseable between statuses (#4642)Eugen Rochko

2017-06-11Fix an error when TagManager.local_url? is called with a bad URI (#3701)ThibG
TagManager.local_url? was sometimes called with an URI with a nil host, leading to a crash in TagManager.local_url?. This fixes moves the already-existing uri.host.blank? check in front to avoid this case.
