This PR hardens artifact URL signing by encoding signature inputs in an
unambiguous binary payload before computing the HMAC.
What it changes:
- replace direct concatenation-style signing inputs with explicit
payload builders
- encode string fields with a length prefix before appending their bytes
- encode integer fields as fixed-width binary values instead of decimal
text
- apply the same hardening to both:
- Actions Artifact V4 signing in `routers/api/actions/artifactsv4.go`
- artifact download signing in `routers/api/v1/repo/action.go`
- add regression tests that verify distinct field combinations produce
distinct payloads and signatures
Why:
The previous signing logic built HMAC inputs by appending multiple
fields without a strongly structured representation. That kind of
construction can create ambiguity at field boundaries, where different
parameter combinations may serialize into the same byte stream for
signing.
This change removes that ambiguity by constructing a deterministic
payload format with explicit boundaries between fields.

- content_encoding contains a slash => v4 artifact
- updated proto files to support mime_type and no longer return errors for upload-artifact v7
- json and txt files are now previewed in browser
- normalized content-disposition header creation
- azure blob storage uploads directly in servedirect mode (no proxying data)
- normalize content-disposition headers based on go mime package
- getting both filename and filename* encoding is done via custom code
Closes#36829

* Use base64.RawURLEncoding to avoid equal sign
* using the nodejs package they seem to get lost
* Support uploads with unspecified length
* Support uploads with a single named blockid
* without requiring a blockmap

I was testing typos-cli and fixed some misspelled wording here.
All changes are internal — no public API fields, database columns,
locale keys, or migration names are affected.
* fixes a fixture status to upload confirmed
* add another fixture as noise to break tests as soon they are exposed
to api
* v4 delete test added check that artifact is no longer visible in
internal api with status pending delete
* removal of http 404 on empty list: actions/upload-artifact@v4 now
backoff on http 404 of ListArtifacts endpoint
* fixes artifacts with pending delete etc. are able to be found and
downloaded if the storage is not freed
* download endpoint has to use 302 redirect
* fake blob download used if direct download not possible
* downloading v3 artifacts not possible
New repo apis based on GitHub Rest V3
- GET /runs/{run}/artifacts (Cannot use run index of url due to not
being unique)
- GET /artifacts
- GET + DELETE /artifacts/{artifact_id}
- GET /artifacts/{artifact_id}/zip
- (GET /artifacts/{artifact_id}/zip/raw this is a workaround for a http
302 assertion in actions/toolkit)
- api docs removed this is protected by a signed url like the internal
artifacts api and no longer usable with any token or swagger
- returns http 401 if the signature is invalid
- or change the artifact id
- or expired after 1 hour

Introduce RequestContext: is a short-lived context that is used to store
request-specific data.
RequestContext could be used to clean form tmp files, close context git
repo, and do some tracing in the future.
Then a lot of legacy code could be removed or improved. For example:
most `ctx.Repo.GitRepo.Close()` could be removed because the git repo
could be closed when the request is done.
Multiple chunks are uploaded with type "block" without using
"appendBlock" and eventually out of order for bigger uploads.
8MB seems to be the chunk size
This change parses the blockList uploaded after all blocks to get the
final artifact size and order them correctly before calculating the
sha256 checksum over all blocks
Fixes#31354
This PR only does "renaming":
* `Route` should be `Router` (and chi router is also called "router")
* `Params` should be `PathParam` (to distingush it from URL query param, and to match `FormString`)
* Use lower case for private functions to avoid exposing or abusing
This PR implemented object storages(LFS/Packages/Attachments and etc.)
for Azure Blob Storage. It depends on azure official golang SDK and can
support both the azure blob storage cloud service and azurite mock
server.
