AuthTask

File: components/tasks/AuthTask.*
Function: RunAuth

Purpose

Authenticates a username/password pair against the backend. Resolves the active server first (LAN probe → WAN fallback, up to SERVER_LAN_FORCE_RETRIES = 3 LAN attempts), then performs a GET to /auth/{user}/{pass} with TIMEOUT_AUTH = 15 000 ms.

XML interface

<component name="AuthTask" extends="Task">
  <interface>
    <!-- inputs -->
    <field id="username"      type="string"    value="" />
    <field id="password"      type="string"    value="" />
    <!-- outputs -->
    <field id="result"        type="assocarray" />
    <field id="done"          type="boolean"   value="false" />
    <field id="statusMessage" type="string"    value="" />
    <field id="statusTick"    type="integer"   value="0" />
  </interface>
</component>

Input fields

Field	Type	Description
`username`	string	Plain-text username.
`password`	string	Plain-text password.

Output fields

Field	Type	Description
`result`	assocarray	Full auth result (see structure below).
`done`	boolean	Set to `true` when the task finishes (success or failure).
`statusMessage`	string	Human-readable progress text (e.g. “Conectando con servidor local…”).
`statusTick`	integer	Incremented each time `statusMessage` changes; observe this to detect updates.

Result structure

result = {
    success                  : false,
    userId                   : "",
    streamUrl                : "",
    subscriberActive         : false,
    subscriberDisabledReason : "",
    errorCode                : -1,      ' AUTH_REASON_* constant
    authReason               : 0,
    errorMsg                 : "",
    rawBody                  : "",
    resolvedServer           : ""
}

Completion signal

Observe done. When done = true, read result. result.success = true means authentication passed; result.subscriberActive confirms the subscriber account is active.

Auth reason codes

PlaylistTask

File: components/tasks/PlaylistTask.*
Function: RunPlaylist

Purpose

Downloads the authenticated M3U8 playlist from /auth/{user}/{pass}/playlist/m3u8/hls and parses it into channel and category arrays. Supports server failover: up to RETRY_MAX = 3 attempts across the server sequence.

XML interface

<component name="PlaylistTask" extends="Task">
  <interface>
    <!-- inputs -->
    <field id="username" type="string" value="" />
    <field id="password" type="string" value="" />
    <!-- outputs -->
    <field id="result"   type="assocarray" />
    <field id="done"     type="boolean"   value="false" />
  </interface>
</component>

Input fields

Field	Type	Description
`username`	string	Credential for the playlist URL.
`password`	string	Credential for the playlist URL.

Output fields

Field	Type	Description
`result`	assocarray	Full playlist result (see structure below).
`done`	boolean	Set to `true` on completion.

Result structure

result = {
    success    : false,
    channels   : [],      ' array of channel objects
    categories : [],      ' array of category name strings
    errorMsg   : "",
    errorCode  : 0,       ' AUTH_REASON_* constant
    authReason : 0,
    rawBody    : "",
    httpCode   : 0
}

Each entry in result.channels is a channel object:

{
    id        : "",      ' tvg-id
    name      : "",      ' tvg-name (or from #EXTINF trailing label)
    logo      : "",      ' tvg-logo URL
    group     : "General",
    number    : -1,       ' channel-number attribute
    url       : "",       ' HLS stream URL
    streamId  : "",       ' extracted from URL path
    contentId : ""        ' streamId if found, else channel number string
}

Completion signal

Observe done. On success, result.channels and result.categories are populated and also written directly to m.global.channelList / m.global.categories.

Logging

The task logs extinf_sample lines (first 3 #EXTINF entries), a logo_summary, and up to 5 channel_sample lines at the GTV_Log level.

AdsPollingTask

File: components/tasks/AdsPollingTask.*
Function: RunAdsPolling

Purpose

Long-running polling task. Performs the initial ads handshake (if ADS_HANDSHAKE_ENABLED = true), then polls the active snapshot endpoint every ADS_POLL_MS = 10 000 ms. Tracks impression versioning and signals session-level auth failures back to MainScene.

XML interface

<component name="AdsPollingTask" extends="Task">
  <interface>
    <!-- inputs -->
    <field id="streamId"            type="string"  value="" />
    <field id="streamPosition"      type="string"  value="" />
    <field id="resetChannel"        type="boolean" value="false" onChange="onResetChannel" />
    <!-- ad output -->
    <field id="adData"              type="assocarray" />
    <field id="adsSnapshot"         type="assocarray" />
    <!-- clear signal -->
    <field id="adsCleared"          type="boolean" value="false" />
    <field id="clearedStreamPosition" type="string" value="" />
    <field id="clearedStreamId"     type="string" value="" />
    <!-- session signals -->
    <field id="userInactive"        type="boolean" value="false" />
    <field id="userInactiveReason"  type="string"  value="" />
    <field id="sessionInvalid"      type="boolean" value="false" />
    <field id="sessionInvalidReason" type="string" value="" />
  </interface>
</component>

Input fields

Field	Type	Description
`streamId`	string	Current stream identifier (from channel `streamId`).
`streamPosition`	string	Channel number string; fallback stream identifier.
`resetChannel`	boolean	Set to `true` when the channel changes; resets `sinceVersion` and triggers an immediate poll.

Output fields

Field	Type	Description
`adData`	assocarray	Normalized first ad from the latest snapshot.
`adsSnapshot`	assocarray	Full snapshot object (version, ads array, stream info).
`adsCleared`	boolean	Toggled `false → true` when the server signals no active ads.
`clearedStreamPosition`	string	Stream position from the clear event.
`clearedStreamId`	string	Stream ID from the clear event.
`userInactive`	boolean	Toggled when the polling response indicates account inactivity.
`userInactiveReason`	string	Localized reason string for the inactive state.
`sessionInvalid`	boolean	Toggled when the response signals credential/password invalidation.
`sessionInvalidReason`	string	Localized reason string.

Completion signal

This is a long-running task; it does not use a done field. Stop it by setting control = "stop".

Poll endpoint

Requests are sent to ADS_API_BASE_URL + ADS_PATH_ACTIVE (default: https://ads.globaltv.lat/api/v1/app/ads/active) with query parameters:

?device_id=<id>&stream_id=<id>&since_version=<ver>

or, if stream_id is unavailable:

?device_id=<id>&stream_position=<number>&since_version=<ver>

Handshake

Before the first poll, TryAdsHandshake() POSTs to ADS_PATH_HANDSHAKE with device and subscriber info. Failures are logged but do not block polling.

ConnectivityTask

File: components/tasks/ConnectivityTask.*
Function: RunConnectivityTask

Purpose

Periodic network health checker. Pings the active server’s health endpoint every 10 seconds and updates m.global.hasInternet / m.global.isOnline. Suppresses log spam by only logging on state transitions.

XML interface

<component name="ConnectivityTask" extends="Task">
  <interface>
    <!-- output -->
    <field id="hasInternet" type="boolean" value="true" />
    <!-- trigger -->
    <field id="checkNow"    type="boolean" value="false" />
  </interface>
</component>

Fields

Field	Direction	Type	Description
`hasInternet`	output	boolean	`true` if the last health ping succeeded. Also written to `m.global.hasInternet`.
`checkNow`	input	boolean	Set to `true` to trigger an immediate check outside the 10-second cycle.

Completion signal

Long-running task. Stopped via control = "stop". Output is written continuously to hasInternet and m.global.

Check logic

sub DoCheck()
    server = GTV_ServerNormalizeBaseUrl(m.global.activeServer)
    if server = ""
        server = GTV_ServerPrimaryConnectivityUrl()
    end if
    result = GTV_PingServer(server)   ' GET to server + PATH_HEALTH, 2500ms timeout
    m.top.hasInternet    = result
    m.global.hasInternet = result
    m.global.isOnline    = GTV_IsOnline()
end sub

HandshakeTask

File: components/tasks/HandshakeTask.*
Function: RunHandshake

Purpose

Performs the initial device handshake with the backend. Probes the server list to find a reachable endpoint, then POSTs device information to PATH_HANDSHAKE = /api/v1/app/devices/handshake. Sets m.global.activeServer, m.global.deviceId, m.global.realtimeMode, and device metadata.

XML interface

<component name="HandshakeTask" extends="Task">
  <interface>
    <!-- output -->
    <field id="result"          type="assocarray" />
    <field id="done"            type="boolean"    value="false" />
    <!-- optional input -->
    <field id="forcedServerUrl" type="string"     value="" />
  </interface>
</component>

Input fields

Field	Type	Description
`forcedServerUrl`	string	If set, bypasses auto-probe and connects only to this URL (used when the user manually selects a server in Settings).

Output fields

Field	Type	Description
`result`	assocarray	Handshake result (see structure below).
`done`	boolean	Set to `true` on completion.

Result structure

result = {
    success      : false,
    server       : "",         ' resolved server base URL
    realtimeMode : "polling",  ' from backend response
    errorCode    : -1,
    errorMsg     : ""
}

Completion signal

Observe done. result.success = true means the handshake succeeded. HTTP 401/403 responses set result.errorCode to that HTTP code but are treated as “auth required” (not a hard failure) by MainScene.

POST payload

payload = {
    platform     : "roku",
    device_id    : deviceId,
    device_model : GTV_GetBrandedDeviceModel(di),
    os_version   : osVersion,
    app_version  : GTV_GetAppVersion()   ' e.g. "1.0.7"
}

MetricsTask

File: components/tasks/MetricsTask.*
Function: RunMetrics

Purpose

Long-running event sink. Waits for trackEvent field writes and POSTs each event to PATH_METRICS = /api/v1/app/metrics/track. Handles ad impression batch events separately via ADS_PATH_IMPRESSIONS.

XML interface

<component name="MetricsTask" extends="Task">
  <interface>
    <!-- input -->
    <field id="trackEvent" type="assocarray" />
    <!-- output -->
    <field id="lastResult" type="assocarray" />
  </interface>
</component>

Fields

Field	Direction	Type	Description
`trackEvent`	input	assocarray	Event object to post. Writing this field triggers `PostEvent`.
`lastResult`	output	assocarray	Result of the most recent post: `{ok, code, server}`.

Event object structure

event = {
    eventType  : "ad_shown",    ' or event_type
    adId       : "<id>",
    adFormat   : "A",
    extraData  : {}              ' optional extra key-value pairs
}

For impression batch events, use eventType = "ad_impression_closed" and add:

{
    eventType  : "ad_impression_closed",
    adId       : "<id>",
    stream_id  : "<id>",
    visible_ms : 4200,
    event_uuid : "<uuid>"
}

Impression events with visible_ms < 1000 are silently dropped. Duplicate event_uuid values within a session are deduplicated.

Completion signal

Long-running task. Stopped via control = "stop". Auth failures (HTTP 401/403) permanently disable metric posting for the remainder of the session.

ServerProbeTask

File: components/tasks/ServerProbeTask.*
Function: RunServerProbe

Purpose

One-shot task that probes a single server URL by calling GTV_PingServer(). Used by SettingsScreen to test connectivity to a specific server profile before applying it.

XML interface

<component name="ServerProbeTask" extends="Task">
  <interface>
    <field id="baseUrl" type="string"    value="" />
    <field id="result"  type="assocarray" />
    <field id="done"    type="boolean"   value="false" />
  </interface>
</component>

Input fields

Field	Type	Description
`baseUrl`	string	Server base URL to probe (e.g. `https://admin.globaltv.lat`).

Output fields

Field	Type	Description
`result`	assocarray	Probe result (see structure below).
`done`	boolean	Set to `true` when the probe completes.

Result structure

result = {
    success : false,
    baseUrl : "<normalized url>",
    message : "Servidor no disponible"
}

success = true means GTV_PingServer() received an HTTP response in the range 200–499 within TIMEOUT_HEALTH = 2 500 ms.

Completion signal

Observe done. Check result.success for the probe outcome.
