When a public image's thumb_url or url fails to load, the fileupload
field fetches its preview once through the authenticated thumb route
(session key in the header) and shows it from an object URL, revoked
when the item is forgotten and on unmount. The preview is reported as
unavailable only when that fetch or the object-URL image fails too.
Protected fields behave as before.
- attach.Store returns attach.ErrProtectedNeedsPrivateBucket for an
is_public false upload while storage.uploads.public_url is set, before
any blob is written
- OpenBucket's public_url line becomes a warning naming the refusal
- OpenBucket validates public_url (absolute http/https, host, no user info, query
or fragment; the error names the key) and records it next to public_path_prefix
- a set public_url logs one start-up line: the bucket behind it must hold only
public files, since it bypasses the is_public check
- attach.PublicURLBase; PublicURL, File.URL and thumbnail URLs use the base when
set and keep the public_path_prefix proxy URLs otherwise
- TestPublicURLSmoke; storage Public URL base section, attachments, configuration
and lagoon README
- DiskExtension: a fixed table of specific sniffed types keeps a matching client
extension or uses the canonical one; generic sniffs keep the client extension
unless it is script-capable (then txt or bin); never asks package mime
- Store names the blob with DiskExtension(sniffed, ext); file_name, the allow-list
and the stored content_type are unchanged
- TestStoreDiskExtensionSmoke: a PNG uploaded as x.html is stored and served as .png,
report.docx keeps .docx, an HTML body named note.txt keeps .txt
- attachments docs on disk names, storage deploy note on nosniff and allow-lists,
lagoon README
- Manifest.Tags from build.tags (^[a-z0-9_]+$, duplicates dropped), round-tripped by SaveManifest
- summer build passes -tags=<list> through goBuildArgs and prints the build tags line
- attach: s3blob imported only by s3_on.go (//go:build summercms_s3); an untagged binary
refuses an s3:// bucket_url naming the tag, build.tags and -tags
- go mod tidy adds the AWS SDK v2 modules as indirect requirements
- storage, modules, scaffolding, configuration and scaling docs plus the lagoon README
The prefix was only trimmed. Without a leading slash ServeMux read its first
segment as a host pattern, so every upload silently answered 404, and a CDN
URL panicked in ServeMux and surfaced as a misleading route conflict. With
storage.uploads.serve on, BuildRouter now refuses a prefix that is not an
absolute URL path (scheme, host, query, fragment, whitespace, wildcard
braces, empty, . or .. segments, or a bare /) with an error naming the key.
The route answered with the blob's stored Content-Type, which attach.Store
sniffs from the bytes, so a public text upload starting with <html> was
served as text/html on the application origin; nosniff does not help when
the declared type is already HTML. Every response now carries a sandboxing
Content-Security-Policy, and a successful response whose type is not a
raster image (JPEG, PNG, GIF, WebP, AVIF) gets Content-Disposition:
attachment, on GET and HEAD. Covers stay inline.
- TestUploadsMount: key off registers nothing; on, a public blob is served
with its content type and nosniff, HEAD has no body, private, missing,
partition and encoded traversal paths 404, an unpublished bucket or
database 404s, a custom prefix is honoured
- mountUploads refuses a plugin route at or under the prefix, so
BuildRouter fails instead of only an identical pattern failing at
Assemble (README and storage docs updated)
- TestAccessLog: pattern and status for 200, handler 404 and recovered
panic, path only for unmatched requests, locale-prefixed requests keep
the pattern, integer duration_ms, no query, header or Authorization
value, ResponseController flush still works
- surf mounts GET {storage.uploads.public_path_prefix}/{path...} on
attach.StaticHandlerPublic when storage.uploads.serve is true
- bucket and database resolved per request; X-Content-Type-Options: nosniff
- surf README, storage and configuration docs describe the key
- attach.PublicURL and (*File).URL build Winter File::getPath() URLs; the
thumbnailer decodes webp via golang.org/x/image v0.46.0 and checks the
image size from the header before decoding
- tide requests carry multipart parts (files beside the fixture pinned by
sha256) encoded with the fixed MultipartBoundary, so PHP and Go receive
byte-identical bodies
- tide masks the random partition, disk name and file id of url/thumb_url
upload URLs while still diffing prefix, size, mode and extension, and
NormalizePublications masks Carbon dates in the published album
- docs/backend: admin controllers, forms, lists and filters, relation
manager, users and permissions, settings, partials and widgets, admin SPA
- docs/services: storage, outbound HTTP, realtime, Web Push, search, parity
testing and the Frontend and AJAX (not provided) page
- Examples for cabana (with testdata/docs YAML), fetchguard, lighthouse and
its centrifugo driver, flare, beachcomber and typesense, tide; lighthouse
and beachcomber TestDocs* regions run on their Postgres harnesses
- concept map rows link their guide pages and the not-provided rows the
Frontend and AJAX page; index lists Backend, Database and Services
- TestDocsRequiredPages asserts the D-08 section order
