Types

type App

type App struct {
	// Listen is the address (of the form host|ip:port) on which the app
	// will listen. It defines CAMLI_APP_LISTEN.
	// If empty, the default is the concatenation of the Camlistore server's
	// Listen host part, and a random port.
	Listen string `json:"listen,omitempty"`

	// BackendURL is the URL of the application's process, always ending in a
	// trailing slash. It is the URL that the app handler will proxy to when
	// getting requests for the concerned app.
	// If empty, the default is the concatenation of the Camlistore server's BaseURL
	// scheme, the Camlistore server's BaseURL host part, and the port of Listen.
	BackendURL string `json:"backendURL,omitempty"`

	// APIHost is URL prefix of the Camlistore server which the app should
	// use to make API calls. It defines CAMLI_API_HOST.
	// If empty, the default is the Camlistore server's BaseURL, with a
	// trailing slash appended.
	APIHost string `json:"apiHost,omitempty"`

	// HTTPSCert is the path to the HTTPS certificate file. If not set, and
	// Camlistore is using HTTPS, the app should try to use Camlistore's Let's
	// Encrypt cache (assuming it runs on the same host).
	HTTPSCert string `json:"httpsCert,omitempty"`
	HTTPSKey  string `json:"httpsKey,omitempty"` // path to the HTTPS key file.
}

App holds the common configuration values for apps and the app handler. See https://camlistore.org/doc/app-environment

type Config

type Config struct {
	Auth    string `json:"auth"`              // auth scheme and values (ex: userpass:foo:bar).
	BaseURL string `json:"baseURL,omitempty"` // Base URL the server advertizes. For when behind a proxy.
	Listen  string `json:"listen"`            // address (of the form host|ip:port) on which the server will listen on.
	// CamliNetIP is the optional internet-facing IP address for this
	// Camlistore instance. If set, a name in the camlistore.net domain for
	// that IP address will be requested on startup. The obtained domain name
	// will then be used as the host name in the base URL.
	// For now, the protocol to get the name requires receiving a challenge
	// on port 443. Also, this option implies HTTPS, and that the HTTPS
	// certificate is obtained from Let's Encrypt. For these reasons, this
	// option is mutually exclusive with BaseURL, Listen, HTTPSCert, and
	// HTTPSKey.
	CamliNetIP         string `json:"camliNetIP"`
	Identity           string `json:"identity"`           // GPG identity.
	IdentitySecretRing string `json:"identitySecretRing"` // path to the secret ring file.
	// alternative source tree, to override the embedded ui and/or closure resources.
	// If non empty, the ui files will be expected at
	// sourceRoot + "/server/camlistored/ui" and the closure library at
	// sourceRoot + "/vendor/embed/closure/lib"

	PackBlobs          bool   `json:"packBlobs,omitempty"`          // use "diskpacked" instead of the default filestorage. (exclusive with PackRelated)
	PackRelated        bool   `json:"packRelated,omitempty"`        // use "blobpacked" instead of the default storage (exclusive with PackBlobs)
	S3                 string `json:"s3,omitempty"`                 // Amazon S3 credentials: access_key_id:secret_access_key:bucket[/optional/dir][:hostname].
	B2                 string `json:"b2,omitempty"`                 // Backblaze B2 credentials: account_id:application_key:bucket[/optional/dir].

	MemoryIndex       bool         `json:"memoryIndex,omitempty"`       // use memory-only indexer.

	// DBNames lists which database names to use for various types of key/value stores. The keys may be:
	//    "index"               (overrides 'dbname' key above)
	//    "queue-sync-to-index" (the sync queue to index things)

}

Config holds the values from the JSON (high-level) server config file that is exposed to users (and is by default at osutil.UserServerConfigPath). From this simpler configuration, a complete, low-level one, is generated by serverinit.genLowLevelConfig, and used to configure the various Camlistore components.

type Publish

type Publish struct {
	// Program is the server app program to run as the publisher.
	// Defaults to "publisher".
	Program string `json:"program"`

	*App // Common apps and app handler configuration.

	// CamliRoot value that defines our root permanode for this
	// publisher. The root permanode is used as the root for all the
	// paths served by this publisher.
	CamliRoot string `json:"camliRoot"`

	// GoTemplate is the name of the Go template file used by this
	// publisher to represent the data. This file should live in
	// app/publisher/.
	GoTemplate string `json:"goTemplate"`

	// CacheRoot is the path that will be used as the root for the
	// caching blobserver (for images). No caching if empty.
	// An example value is Config.BlobPath + "/cache".
	CacheRoot string `json:"cacheRoot,omitempty"`

	// SourceRoot optionally defines the directory where to look for some resources
	// such as HTML templates, as well as javascript, and CSS files. The
	// default is to use the resources embedded in the publisher binary, found
	// in the publisher app source directory.
	SourceRoot string `json:"sourceRoot,omitempty"`
}

Publish holds the server configuration values specific to a publisher, i.e. to a publish prefix.

type ScanCab

type ScanCab struct {
	// Program is the server app program to run as the scanning cabinet.
	// Defaults to "scanningcabinet".
	Program string `json:"program"`

	// Prefix is the URL path prefix where the scanning cabinet app handler is mounted
	// on Camlistore.
	// It always ends with a trailing slash. Examples: "/scancab/", "/scanning/".
	Prefix string `json:"prefix"`

	// Auth is the authentication scheme and values to access the app.
	// It defaults to the server config auth.
	// Common uses are HTTP basic auth: "userpass:foo:bar", or no authentication:
	// "none". See https://camlistore.org/pkg/auth for other schemes.
	Auth string `json:"auth"`

	// App is for the common apps and app handler configuration.
	*App
}

ScanCab holds the server configuration values specific to a scanning cabinet app. Please note that the scanning cabinet app is still experimental and is subject to change.
