2023-05-24 r/6194 feat(tazjin/tgsa): add gpt-3 powered message translation featureVincent Ambo1-7/+79
this is slow and often overloaded, but it's kind of cool when it works. this translation method deals much better with the kind of slang you'd see in telegram posts than any other method.

2023-04-12 r/6096 feat(tazjin/tgsa): support extracting fallback message from previewVincent Ambo1-11/+37
some telegram channels do not allow embedding of messages, but do allow a preview to be shown on twitter. this preview is just embedded in the html, and can be scraped out if no message was found. technically this preview also contains image links, but they are to very low resolution, thumbnail-style images so i decided not to include them here.

uses the tgsa-proxied media links in the message bbcode, leading to stable image serving even if telegram swaps cdn addresses around, as long as their embed page is någorlunda the same.

2022-05-14 r/4077 feat(tazjin/tgsa): add stable redirects to telegram imagesVincent Ambo1-5/+53
telegram occasionally changes the upstream urls at which images are served, with old/new partially overlapping in time afaict. with this commit, a new endpoint is added to tgsa at /img/$user/$post_id/$img_idx which serves a redirect to the actual image url that telegram had returned within the last hour (i.e. as per the cache). next step is to use these image urls in the bbcode itself.

this lays the groundwork for adding another handler and returning handler results as `anyhow::Result<rouille::Response>`. needed for the image redirect stuff.

2022-05-14 r/4075 refactor(tazjin/tgsa): factor out cache access helperVincent Ambo1-13/+21
factor out a function to access telegram posts from the cache, fetching them anew if required. a small behavioural change means that the program now takes a write lock when fetching a post, to avoid simultaneously fetching the same post many times (quite likely once it serves image redirects).

2022-05-14 r/4074 feat(tazjin/tgsa): Expire cached telegram entries after one hourVincent Ambo1-5/+22
Telegram expires certain links in messages after some (unknown) amount of time; this commit is the first step to working around that by providing an image URL proxy. In order to do that, we tick two important boxes here: 1. Store an extensible data structure in the cache. 2. Expire them periodically.

2022-04-19 r/3975 chore(tgsa): Remove shortening of image linksVincent Ambo1-25/+7
The link shortening was in place because posts with image URLs that were too long would not get recognised as valid image links. astral has fixed this after my report: https://forums.somethingawful.com/showthread.php?threadid=3999866 I verified this with the example post that has a bunch of images and such in it. Thanks astral!
