i'll keep this on a separate branch for now while i experiment with other possible alternatives, but for now both our hacky implementation especially, and more popular ones (like anubis) aren't looking too great on the deterrent front: https://github.com/eternal-flame-AD/pow-buster

This uses a much faster method of generating request IDs using an atomically updated counter instead of a mutex lock and read of /dev/random.

updates our codeberg.org/gruf/go-kv log key-value formatting library to latest version, which comes with some maaaaaaajor speed boosts in the form of:
- very minimal reflect.Value{} usage
- caching prepared formatting functions per type
~~still a work-in-progress until i make a release tag on the go-kv repository, which itself is waiting on published benchmark results in the README and finishing writing some code comments~~
benchmarks so far show this to be ~3x faster than the "fmt" stdlib package on average, when run across a wide variety (106 different types) of test cases, while still creating more visually friendly log output and actually recursing down nested struct ptrs

# Description
This updates our proof-of-work middleware, NoLLaMas, to work on a more easily configurable algorithm (thank you f0x for bringing this to my attention!). Instead of requiring that a solution with pre-determined number of '0' chars be found, it now pre-computes a result with a pre-determined nonce value that it expects the client to iterate up-to. (though with some level of jitter applied, to prevent it being too-easily gamed). This allows the user to configure roughly how many hash-encode rounds they want their clients to have to complete.

This pull request adds a very simple ad-hoc ListenBrainz widget to the frontend web view, with progressive enhancement (in all fail states it just falls back to rendering the field as normal).
This necessitated adding the ListenBrainz API endpoint to the `connect-src` part of our Content-Security-Policy header. We might want to tweak this to only add that endpoint to `connect-src` for profiles, and then only for profiles that include a ListenBrainz field, but this would require significant dicking about with the middleware, and checks inside the app logic, such that it might not be worthwhile (after all, we control all the scripts right now anyway).

# Description
Fixes a bug in the new timeline code in which the limit query parameter wasn't always being fulfilled, in which case some clients like Tusky would then assume it didn't need to add a "load more" placeholder view even when there were more statuses to be loaded. This also fiddles around a bit in the logging middleware handler to add some more code comments, and add logging of full request URIs when it is safe to do so.

This adds a proof-of-work based scraper deterrence to GoToSocial's middleware stack on profile and status web pages. Heavily inspired by https://github.com/TecharoHQ/anubis, but massively stripped back for our own usecase.
Todo:
- ~~add configuration option so this is disabled by default~~
- ~~fix whatever weirdness is preventing this working with CSP (even in debug)~~
- ~~use our standard templating mechanism going through apiutil helper func~~
- ~~probably some absurdly small performance improvements to be made in pooling re-used hex encode / hash encode buffers~~ the web endpoints aren't as hot a path as API / ActivityPub, will leave as-is for now as it is already very minimal and well optimized
- ~~verify the cryptographic assumptions re: using a portion of token as challenge data~~ this isn't a serious application of cryptography, if it turns out to be a problem we'll fix it, but it definitely should not be easily possible to guess a SHA256 hash from the first 1/4 of it even if mathematically it might make it a bit easier
- ~~theme / make look nice??~~
- ~~add a spinner~~
- ~~add entry in example configuration~~
- ~~add documentation~~

* [chore] Upgrade golangci-lint, ignore existing int overflow warnings
There is a new lint for unchecked int casts. Integer overflows are bad,
but the old code that triggers this lint seems to be perfectly fine.
Instead of disabling the lint entirely for new code as well, grandfather
in existing code.
* fix golangci-lint documentation link

* get rid of remaining nolint:gosec
* swagger updates

inlining (#3323)

* remove unused global variable

|
* [chore] Synchronise our robots.txt with upstream
* [feature] Add headers to escape AI crawlers
This adds 2 headers that a number of AI crawlers respect to signal that
content should not be included in their datasets.
|
|
* Set frame-ancestors in the CSP
This ensures we can't be loaded/embedded in an iframe. It also sets the
older X-Frame-Options for fallback.
* Disable MIME type sniffing
* Set Referrer-Policy
This sets the policy such that browsers will never send the Referer
header along with a request, unless it's a request to the same protocol,
host/domain and port. Basically, only send it when navigating through
our own UI, but not anything external.
The default is strict-origin-when-cross-origin when unset, which sends
the Referer header for requests unless it's going from HTTPS to HTTP
(i.e a security downgrade, hence the 'strict').

* [bugfix] CSP policy fixes for S3 in non-proxied mode
* It should be img-src
* In both img-src and media-src we still need to include 'self'
|
|
* [bugfix] Add s3 endpoint as image-src and media-src for CSP
* use https if secure
* reorder comment
|
|
This adds the CSP header with a policy of only loading from the same
domain. We don't make use of external media, CSS, JS, fonts, so we don't
ever need external data loaded in our context.
When building a DEBUG build, the policy gets extended to include
localhost:*, i.e localhost on any port. This keeps the live-reloading
flow for JS development working. localhost and 127.0.0.1 are considered
to be the same so mixing and matching those doesn't result in a CSP
violation.
