2019-07-07luci-base: luci.js: don't abort finished xhr objectsJo-Philipp Wich
Calling abort() on a finished xhr object will clear properties such as status which can confuse code relying on legacy LuCI request helper functions. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: ui.js: fix rendering of rich dropdown placeholdersJo-Philipp Wich
Placeholders may be HTML elements instead of plain strings, so do not use innerHTML to assign them but rely on L.dom.content() instead. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: implement further ubus callsJo-Philipp Wich
Implement new ubus rpcd backend calls for later use in the frontend: - netdevs: dump information about Linux network devices present - boardjson: dump /etc/board.json if present - offload_support: query whether netfilter offloading is supported Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: fix handling of large ubus HTTP requestsJo-Philipp Wich

2019-07-07luci-base: add client-side implementation of luci.model.firewallJo-Philipp Wich
Introduce firewall.js, a client side reimplementation of the luci.model.firewall class. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: add client-side implementation of luci.model.networkJo-Philipp Wich
Introduce network.js, a client side reimplementation of the luci.model.network class. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: add client-side prng libraryJo-Philipp Wich
Introduce a new tools.prng JS library which implements the musl libc srand() and rand() calls to produce identical pseudo random number sequences in the browser which is needed for the string to color conversion later on. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: make require() failures catcheableJo-Philipp Wich
Refactor L.require() to use L.raise() instead of L.error() to signal class loading failures. This allows callers to handle class loading errors in a graceful manner. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: split off CBI validations into separate classJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: rework L.error()Jo-Philipp Wich
Factor out an L.raise() function out of L.error() which constructs and throws an exception object. Rework the remaining L.error() function to internally use L.raise() to construct exceptionts to render. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: form.js: default to unlimited dropdown sizeJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: ui.js: improve dropdown behaviourJo-Philipp Wich

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: rpc.js: drop batch apiJo-Philipp Wich
Now that LuCI.Request is transparently coalescing requests, there is no need for the rather cumbersome batch()/flush() api in rpc.js. Also refactor the code to get rid of the rpcRequestRegistry indirection and remove superfluous promises which simplifies the code a lot. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-mod-system: rework leds.js and system.js viewsJo-Philipp Wich
- Drop manual RPC batch usage - Use LuCI.Poll for status updates Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Extend LuCI.Request to automatically coalesce subsequent requests to ubus resources into single batch requests. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: rpc.js: make base URL configurableJo-Philipp Wich
Implement setters and getters for the base URL prefix used and also implement a session ID getter while we're at it. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: introduce generic LuCI.PollJo-Philipp Wich
Introduce a new LuCI.Poll class which is able to repeat any promise based function and not strictly tied to HTTP request semantics. Also rework LuCI.Request.Poll and XHR.Poll as well as LuCI.start(), LuCI.stop(), LuCI.halt() etc. to redirect to the new api. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: enable strict modeJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: introduce form.jsJo-Philipp Wich
Add a new client side form.js library which is a more or less direct reimplementation of the Lua side cbi.lua in JavaScript. Due to its client side nature, it supports a number of features which would be hard to realize on the server side, such as drag&drop sorting, modal sub-map dialogs, reload-free editing etc. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: switch from server side to client side widget markupJo-Philipp Wich
Do not render standard widgets like checkboxes, select boxes, text input fields etc. on the server side anymore but utilize the ui.js primitives instead. This avoids logic duplication between server side cbi templates and JS widgets in the future. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: cbi.js, ui.js: add custom validation callbacks, new ui widgetsJo-Philipp Wich
Implement further widget primitives like text inputs or checkboxes and support custom validation callback functions when instantiating CBI validators. Also add support initializing ui.js widgets from the "data-ui-widget" HTML attribute. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: add client based view actionsJo-Philipp Wich
Introduce a new view() target for CBI dispatch nodes, as long with the required template and plumbing work in luci.js to allow requiring view classes. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: tweak error handlingJo-Philipp Wich
If the ui class is loaded, use its modalDialog facility to display runtime errors, alternatively render them into the maincontent area. Also prevent duplication of stack trace information and throw a low level error on session expiration to allow higher layers to properly handle it. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: replace uci change pages with client side modal dialogJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: add uci.js and rpc.js classesJo-Philipp Wich
Add a new rpc.js class which provides low level facilities to exchanges messages with the ubus rpc endpoint. Also introduce a new uci.js class which provides client side uci manipulation routines. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: add ubus-http gatewayJo-Philipp Wich
Add an admin/ubus route mimicking the native uhttpd-mod-ubus protocol. The main difference to the native protocol is that this gateway requires no additional per-object/procedure ACL setup on the router side and that it is located under the same prefix as LuCI itself, allowing the reuse of the session login cookie. This route is meant to be a transitional mechanism until client side RPC calls are eventually migrated to uhttpd-mod-ubus completely. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: move dropdown, combox and dynlist widget code to L.uiJo-Philipp Wich
Move the widget code to the ui class and replace it with compatibility shims in cbi.js Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: add L.dom.data()Jo-Philipp Wich
Add a new data() function which allows to attach arbitrary JS data to DOM elements. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: cbi.js: support field validation for formless inputsJo-Philipp Wich
JS CBI fields have no parent form element anymore. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: cbi.js: untangle dropdown and dynlists from dependency updateJo-Philipp Wich
In order to prepare the move of the dynlist and dropdown widgets into the LuCI ui class, remove the direct calls to cbi_d_update() and replace them with custom events instead. Extend cbi_init() to handle these custom events and to invoke cbi_d_update() when receiving them. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: add L.bind() helperJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: consolidate error handlingJo-Philipp Wich

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: split ui helper functions into external ui.jsJo-Philipp Wich
Use the new class loader infrastructure to move gui specific functionality out of the luci.js core and dispatch a new event 'luci-loaded' which is fired once all external classes have been fetched. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: add dynamic class loaderJo-Philipp Wich
Introduce L.require() to fetch additional JavaScript classes. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: convert LuCI to Class instanceJo-Philipp Wich
Also hijack cbi_init() and call it after the LuCI DOM setup. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2019-07-07luci-base: luci.js: add HTTP request functionsJo-Philipp Wich
Add a fetch() inspired HTTP request utility class to luci.js and replace the old xhr.js class with a stub using the new request api. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
