Three things in one move:
1. Centralize per-type size caps in config/trypost.php under media.max_size_mb.
The MediaType enum now reads from there:
MediaType::Image->maxSizeInMb() // 10 (env: MEDIA_IMAGE_MAX_SIZE_MB)
MediaType::Video->maxSizeInMb() // 1024 (env: MEDIA_VIDEO_MAX_SIZE_MB)
Plus convenience helpers maxSizeInBytes() and maxSizeInKb() so callers
don't have to multiply themselves. StoreAssetRequest now uses
MediaType::Video->maxSizeInKb() in its 'max:' rule and mimes derived
from MediaType::{Image,Video}->allowedMimeTypes(). storeChunked
validation moved to the new StoreChunkedAssetRequest FormRequest
(also reads from the enum). MediaAttacher uses
MediaType::Video->maxSizeInBytes() as the streaming-abort threshold
and enforces the per-type cap after MIME resolution.
2. Drop MediaType::Document. We never accepted PDFs anywhere — the
StoreAssetRequest mimes list excluded them, the storeChunked
extension regex excluded them, MediaAttacher excluded them. The only
places that referenced Document were:
- Platform::allowedMediaTypes for LinkedIn/LinkedInPage (declared
but unreachable)
- HasMedia::getMediaType fallback when MIME wasn't image/video/*
Both now cleaned up. HasMedia::getMediaType throws
InvalidArgumentException for unsupported MIMEs instead of silently
returning a fake 'document' type. Platform::LinkedIn now matches
every other social platform: [Image, Video].
3. Add MediaType::fromMime($mime): ?self — replaces the inline mime →
type loop that MediaAttacher used to roll. Returns null for
unsupported MIMEs (caller decides how to react).
Tests:
- MediaTypeTest rewritten for the new shape (no Document, config-driven
sizes, fromMime + size-helper coverage).
- PlatformTest no longer asserts Document on LinkedIn.
- HasMediaTest replaces the 'detects document type' case with one that
asserts the throw on unsupported MIMEs. The 'add media from path'
test now uses real PNG bytes from the fixture.
- AssetControllerTest chunked tests use real PNG bytes and assert 422
(FormRequest unprocessable) for malformed Content-Range headers,
matching the new validation layer.
