Raw files ​

A file path in a repository works like a file on a web server. PUT stores a body as the next version of a path. GET returns the current version. Use it from build scripts and CI jobs that have curl or PowerShell and nothing else.

The address is the same for all three methods:

text
https://<host>/api/v1/repositories/<repository>/raw/<path>

For example: https://arkvory.example/api/v1/repositories/releases/raw/builds/game/1.4/GameSetup.exe.

Store a file ​

You need a repository and a key with write access. See Accounts and keys. Send the key as Authorization: Bearer <key>. Raw files accept no other kind of authentication.

bash
export ARKVORY_KEY="$(cat ~/.arkvory/key)"
URL="https://arkvory.example/api/v1/repositories/releases/raw/builds/game/1.4/GameSetup.exe"

curl --fail-with-body -sS -T ./GameSetup.exe \
  -H "Authorization: Bearer $ARKVORY_KEY" \
  "$URL"
powershell
$headers = @{ Authorization = "Bearer $env:ARKVORY_KEY" }
$url = 'https://arkvory.example/api/v1/repositories/releases/raw/builds/game/1.4/GameSetup.exe'
Invoke-RestMethod -Method Put -InFile .\GameSetup.exe -Headers $headers -Uri $url
bash
wget -qO- --method=PUT --body-file=GameSetup.exe \
  --header="Authorization: Bearer $ARKVORY_KEY" "$URL"

Give curl -T the full address of the file, not of a folder. Encode characters in the path that a URL does not allow: write a space as %20, # as %23 and ? as %3F.

The answer is JSON. A new file or new bytes return 201:

json
{
  "path": "builds/game/1.4/GameSetup.exe",
  "revision": 1,
  "created": true,
  "artifact": { "id": "00000000-0000-4000-8000-000000000001", "size": "1048576", "sha256": "…" }
}

If the path already holds exactly these bytes, the answer is 200 with "created": false and the same revision. Nothing is stored. A step of a CI job can run again without creating a new version. size is a string of decimal digits.

Send a checksum ​

Send the SHA-256 of the file with X-Checksum-Sha256, and the length with Content-Length. curl -T and PowerShell send the length for a file. Then the server writes the bytes directly into storage in one pass and checks them there. A wrong checksum returns 422 with the code integrity_mismatch, stores nothing, and keeps the path as it was.

bash
curl --fail-with-body -sS -T ./GameSetup.exe \
  -H "Authorization: Bearer $ARKVORY_KEY" \
  -H "X-Checksum-Sha256: $(sha256sum GameSetup.exe | cut -d' ' -f1)" \
  "$URL"
powershell
$headers['X-Checksum-Sha256'] = (Get-FileHash .\GameSetup.exe -Algorithm SHA256).Hash.ToLower()
Invoke-RestMethod -Method Put -InFile .\GameSetup.exe -Headers $headers -Uri $url

Without the checksum, or with a chunked body that has no Content-Length, the server first writes the body into a temporary file and hashes it. Then it stores it. This needs up to twice the size of the file on the disk of the server for a short time, and a second pass over the bytes. The server removes temporary files that a failure left behind after one day.

When you send the checksum and the length, and the path already holds these bytes, the server answers 200 without reading the body, and closes the connection.

Create only ​

A PUT reads only one condition, If-None-Match: *. With it, the server stores the file only if the path does not exist. Otherwise it answers 409 with the reason already_exists, also when the bytes are the same. Any other value of If-None-Match on a PUT returns 400.

bash
curl --fail-with-body -sS -T ./notes.txt \
  -H "Authorization: Bearer $ARKVORY_KEY" -H "If-None-Match: *" \
  "https://arkvory.example/api/v1/repositories/releases/raw/docs/notes.txt"

Two writers ​

When two requests change the same path at the same time, the first wins. The later one gets 409 with the reason revision_mismatch, and the path keeps the content of the winner. Run the request again to make a new revision. The uploaded bytes of the loser stay as an artifact without a path until retention removes them.

Read a file ​

GET returns the current version of the path. HEAD returns the headers only.

bash
curl --fail-with-body -sS -H "Authorization: Bearer $ARKVORY_KEY" -o GameSetup.exe "$URL"
powershell
$ProgressPreference = 'SilentlyContinue'
Invoke-WebRequest -Headers $headers -Uri $url -OutFile .\GameSetup.exe
bash
wget --header="Authorization: Bearer $ARKVORY_KEY" -O GameSetup.exe "$URL"

The answer headers:

HeaderValue
ETag"sha256:<digest>": the SHA-256 of the content, in quotes
Content-LengthThe size of the file
Accept-Rangesbytes
Content-TypeAlways application/octet-stream
Content-Dispositionattachment with the last segment of the path as the file name
X-Arkvory-Artifact-IdThe ID of the artifact that holds this version

An unknown path returns 404.

Ranges and conditional requests ​

Request headerEffect
Range: bytes=0-1023206 with the requested part and Content-Range. A start past the end of the file returns 416 with Content-Range: bytes */<size>.
Range: bytes=-1024The last 1024 bytes
Range: bytes=1048576-From the offset to the end
If-Range: "sha256:…"Applies the Range only if the ETag is exactly this one. If the path has a new version, you get the whole new file.
If-None-Match: "sha256:…"304 with no body if the ETag is the same. It works with HEAD too.

Only one range per request is supported. A request with several ranges returns the whole file.

A path can get a new version at any time, and a GET resolves the path again. To continue a download safely, remember the ETag of the first answer and send it as If-Range:

bash
etag=$(curl -sSI -H "Authorization: Bearer $ARKVORY_KEY" "$URL" | awk 'tolower($1)=="etag:" {print $2}' | tr -d '\r')
curl -sS -H "Authorization: Bearer $ARKVORY_KEY" -H "If-Range: $etag" \
  -H "Range: bytes=1048576-" "$URL" >> GameSetup.part

To skip a download when the file has not changed, send the ETag you stored last time:

bash
curl -sS -o /dev/null -w '%{http_code}\n' -H "Authorization: Bearer $ARKVORY_KEY" \
  -H 'If-None-Match: "sha256:<digest>"' "$URL"

For large files, arkvoryctl get downloads with resume and verifies the SHA-256 for you.

Paths and versions ​

A raw file is a file by path. Every PUT with new bytes adds a revision to the path: revision 1, 2, 3 and so on. Earlier revisions stay. Bytes are never replaced, because each revision points to its own immutable artifact, named after the last segment of the path.

  • GET on the raw address always gives the current revision.
  • To see all revisions of a path, read its history: getAssetHistory, or محفوظات الملفات in the console.
  • To read an older revision, getAssetRevision returns its artifact. Download it with the content address of the artifact.
  • To go back to an old revision, use restoreAsset. It adds a new revision that points to the old bytes.
  • To list the paths of a repository by prefix, use listAssetPage.
  • A path cannot be deleted. The history stays. Retention does not remove artifacts that a path revision uses.

The same operations are in the SDK (client.raw.putRawFile, downloadRawFile) and in arkvoryctl (put, get).

Path rules ​

RuleValue
Length1 to 1024 characters
FoldersSegments separated by /
Not allowedAn empty segment (a//b), . or .., a backslash, a colon and control characters

curl and browsers remove . and .. from a URL before they send it, so such a path never arrives. A path that breaks the rules returns 400.

Permissions ​

Personal tokens and file keys get read or write access to the repository. Service keys get exact actions.

OperationService key actionsPersonal token or file key
GET, HEADcontent.readRead access
PUTupload.create, upload.write, upload.complete, asset.read, asset.write, artifact.readWrite access, token scope read-write

A deployment agent that only downloads needs the action content.read.

A read gateway accepts GET and HEAD only. A mirror serves reads and refuses PUT with 409 and the reason mirror_read_only.

Limits ​

LimitValue
File sizeThe maximum object size of the installation, ARKVORY_MAX_OBJECT_BYTES (about 10 TiB by default)
One PUT requestMust finish within 30 minutes and must not pause for more than 30 seconds (ARKVORY_UPLOAD_DEADLINE_MS, ARKVORY_UPLOAD_IDLE_TIMEOUT_MS). These are also the highest allowed values.
Uploads at the same time2 per server and 1 per key by default (ARKVORY_MAX_UPLOADS, ARKVORY_MAX_UPLOADS_PER_PRINCIPAL). A waiting request gives up after 20 seconds with 503.
Downloads at the same time16 per server and 4 per key by default
QuotaThe file counts against the repository quota and the capacity of the installation

A single PUT has no resume: after a failure, it starts again from the first byte. Use raw files for small and medium files and for scripts. For large files or slow networks, use arkvoryctl put or the SDK. They upload in parts, continue after a failure and check the SHA-256. They also store the file as a revision of a path. The variables are described in Environment variables.

Unity Addressables ​

Addressables load the catalog and the bundles with plain GET requests, so a build folder can live under a raw path. This suits internal builds, QA and tools. It does not suit players on the public internet: a raw read always needs a key, a download link expires within 24 hours, and a key inside a shipped player is not a secret.

Upload the folder with arkvoryctl put. Files whose bytes did not change are not sent again. Use one folder per build, because a path always returns its newest revision, and an old catalog must not meet new bundles:

bash
cd ServerData/StandaloneWindows64
find . -type f | while read -r file; do
  arkvoryctl put "$file" "addressables/game/$BUILD/StandaloneWindows64/${file#./}" || exit 1
done
powershell
$root = (Resolve-Path .\ServerData\StandaloneWindows64).Path
Get-ChildItem $root -Recurse -File | ForEach-Object {
  $relative = $_.FullName.Substring($root.Length + 1) -replace '\\', '/'
  arkvoryctl put $_.FullName "addressables/game/$env:BUILD/StandaloneWindows64/$relative"
  if ($LASTEXITCODE -ne 0) { exit $LASTEXITCODE }
}

Set the remote load path of the Addressables profile to the raw address of that folder, for example https://arkvory.example/api/v1/repositories/releases/raw/addressables/game/<build>/[BuildTarget]. Give the player a key that can only read: a personal access token with read access, or a service key with the action content.read. Raw files accept the key only in the Authorization header, so set it on every request:

csharp
Addressables.WebRequestOverride = request =>
{
    if (request.url.StartsWith("https://arkvory.example/"))
        request.SetRequestHeader("Authorization", "Bearer " + readKey);
};

The property is Addressables.WebRequestOverride in Addressables 1.x; check the name in your version. This is a pattern, not a tested integration.

Troubleshooting ​

Errors are JSON documents with code, reason, message and requestId. See Errors. Give the requestId to your administrator to find the request in the server log.
