Added support for OpenTelemetry via {otel}. By default, if otel::is_tracing_enabled() returns TRUE, then shiny will record all OpenTelemetery spans. See {otelsdk}’s Collecting Telemetry Data for more details on configuring OpenTelemetry.
Shiny now supports OpenTelemetry via {otel}. By default, if otel::is_tracing_enabled() returns TRUE, then shiny records all OpenTelemetry spans. See {otelsdk}’s Collecting Telemetry Data for more details on configuring OpenTelemetry. (#4269, #4300)
Supported values for options(shiny.otel.bind) (or Sys.getenv("SHINY_OTEL_BIND")):
Supported values for options(shiny.otel.bind) (which defaults to Sys.getenv("SHINY_OTEL_BIND") if set) are:
"none" - No Shiny OpenTelemetry tracing."all" [default] - All Shiny OpenTelemetry tracing. Currently equivalent to "reactivity".Spans are recorded for:
+OpenTelemetry spans are recorded for:
session_start: Wraps the calling of the server() function. Also contains HTTP request within the attributes.reactive debounce, reactive throttle: Captures the calculation (including any async promise chains) of a debounce()d or throttle()d reactive expression.reactiveFileReader, reactivePoll: Captures the calculation (including any async promise chains) of a reactiveFileReader() or reactivePoll().ExtendedTask: Captures the calculation (including any async promise chains) of an ExtendedTask.Set reactiveVal <name> - When a reactiveVal() is setSet reactiveValues <name>$<key> - When a reactiveValues() element is setoptions(shiny.otel.sanitize.errors = FALSE).options(shiny.otel.sanitize.errors = FALSE).Set ExtendedTask <name> <value> - When an ExtendedTask’s respective reactive value (e.g., status, value, and error) is set.<ExtendedTask name> add to queue - When an ExtendedTask is added to the task queue.All logs and spans contain the session.id attribute.
All OpenTelemetry logs and spans will contain a session.id attribute containing the active session ID.
icon argument of updateActionButton()/updateActionLink() nows allows values other than shiny::icon() (e.g., fontawesome::fa(), bsicons::bs_icon(), etc). (#4249)updateActionButton() and updateActionLink() now accept values other than shiny::icon() for the icon argument (e.g., fontawesome::fa(), bsicons::bs_icon(), etc). (#4249)updateActionButton()/updateActionLink() now correctly renders HTML content passed to the label argument. (#4249)
Fixed an issue where updateSelectizeInput(options = list(plugins="remove_button")) could lead to multiple remove buttons. (#4275)
Showcase mode now uses server-side markdown rendering with the commonmark package, providing support for GitHub Flavored Markdown features (tables, strikethrough, autolinks, task lists). While most existing README.md files should continue to work as expected, some minor rendering differences may occur due to the change in markdown processor. (#4202, #4201)
debounce(), reactiveFileReader(), reactivePoll(), reactiveValues(), and throttle() now attempt to retrieve the assigned name for the default label if the srcref is available. If a value cannot easily be produced, a default label is used instead. (#4269, #4300)
The default label for items described below will now attempt to retrieve the assigned name if the srcref is available. If a value can not easily be produced, a default label will be used instead. This should improve the OpenTelemetry span labels and the reactlog experience. (#4269, #4300)
bindCache() and reactive()
updateActionButton() and updateActionLink() now correctly render HTML content passed to the label argument. (#4249)
updateSelectizeInput() no longer creates multiple remove buttons when options = list(plugins="remove_button") is used. (#4275)

The return value of actionButton()/actionLink() changed slightly: label and icon are wrapped in an additional HTML container element. This allows for: 1. updateActionButton()/updateActionLink() to distinguish between the label and icon when making updates and 2. spacing between label and icon to be more easily customized via CSS.
actionButton() and actionLink() now wraps label and icon in an additional HTML container element. This allows updateActionButton() and updateActionLink() to distinguish between the label and icon when making updates, and allows spacing between label and icon to be more easily customized via CSS.R/extended-task.R
