| 279 | When you submit a javascript to the server, it will be executed
|
|---|
| 280 | on a sandbox on the server. Before the event is loaded from a file
|
|---|
| 281 | and made available within the sandbox. Generally, the sandbox
|
|---|
| 282 | can easily be enhanced, e.g. with algorithms available in php.
|
|---|
| 283 | This can be done on request. After execution, the result returned
|
|---|
| 284 | by the script is then displayed in the camera display.

|---|
| 287 | Simply for security reasons. To avoid tranferring the event to the client's
|
|---|
| 288 | browser, the script must be executed on the server side. Also Python
|
|---|
| 289 | and PHP offer the possibility to execute scripts within a program,
|
|---|
| 290 | they do not have any security feature to avoid for exmple access to the
|
|---|
| 291 | local disk. The V8 Javascript engine however, is very limited in
|
|---|
| 292 | functionality and therefore ideally suited for a sandboxed and
|
|---|
| 293 | therefore safe excution on the server. Any other solution is welcome.
|
|---|

| 295 | <H3>Javascript hints!</H3>
|
|---|
| 296 | Please note that in Javascript only basic data typed (number, etc)
|
|---|
| 297 | are copied in an assignment. In all other cases, only a reference
|
|---|
| 298 | is copied. For example, the following code snippet does not return 2
|
|---|
| 299 | as you might expect but 7!
|
|---|
| 300 | <pre><!--<textarea id="code0" style="height:auto;overflow-x:auto;overflow-y:hidden;">-->
|
|---|
| 301 | var arr = [ 0, 1, 2, 3 ];
|
|---|
| 302 | var cpy = arr;
|
|---|
| 303 | cpy[2] = 7;
|
|---|
| 304 | print(arr[2]);
|
|---|
| 305 | </pre><!--</textarea>-->
|
|---|
| 306 | To avoid that, the global namespace implements a clone function.
|
|---|
| 307 | For exmaple, the following code snippet will return the expected output:
|
|---|
| 308 | <pre><!--<textarea id="code1">-->
|
|---|
| 309 | var arr = [ 0, 1, 2, 3 ];
|
|---|
| 310 | var cpy = $.clone(arr);
|
|---|
| 311 | cpy[2] = 7;
|
|---|
| 312 | print(arr[2]);
|
|---|
| 313 | </pre><!--</textarea>-->

| 315 | <H3>Javascript arrays</H3>
|
|---|
| 316 | Note that javascript arrays have some very powerful member functions.
|
|---|
| 317 | For a description see for example
|
|---|
| 318 | <A HREF="http://www.tutorialspoint.com/javascript/javascript_arrays_object.htm">here</A>
|
|---|
| 319 | or search google for function like <i>map</i> or <i>reduce</i>.

|
|---|
| 321 | <H3>The global object $</H3>
|
|---|
| 322 |
|
|---|
| 323 | The environment provides a global object (namesapce) called $ with the following members:
|
|---|
| 324 | <table>
|
|---|
| 325 | <tr><td>$.event</td><td>The event header information as obtained from the file</td></tr>
|
|---|
| 326 | <tr><td>$.event.numEvents</td><td>Number of events in the file</td></tr>
|
|---|
| 327 | <tr><td>$.event.numRoi</td><td>Number of samples per pixel</td></tr>
|
|---|
| 328 | <tr><td>$.event.numPix</td><td>Number of pixels</td></tr>
|
|---|
| 329 | <tr><td>$.event.eventNumber</td><td>Event number</td></tr>
|
|---|
| 330 | <tr><td>$.event.triggerNumber</td><td>Trigger number</td></tr>
|
|---|
| 331 | <tr><td>$.event.triggerType</td><td>Trigger type</td></tr>
|
|---|
| 332 | <tr><td>$.event.unixTime[2]</td><td>Timestamp when the event arrived at the event builder</td></tr>
|
|---|
| 333 | <tr><td>$.data[numPix][numRoi]</td><td>Theevent data</td></tr>
|
|---|
| 334 | </table>
|
|---|
| 335 |
|
|---|
| 336 | <H3>Stack traces</H3>
|
|---|
| 337 | Please note that due to some interna, the line numbers in the
|
|---|
| 338 | stack trace shown in case of runtime errors are by one line too high.
|
|---|
| 339 |
|
|---|
| 340 | <H3>Editor 1 (proc)</H3>
|
|---|
| 341 |
|
|---|
| 342 | <I>proc</I> can return an array with numRoi entries or an array with up to
|
|---|
| 343 | four sub-arrays each of nRoi entries. They will be displayed in the graph.
|
|---|
| 344 | The chosel pixel is available as <I>pixel</I>.
|
|---|
| 345 | The most simple is to just return the selected pixel data unprocssed:
|
|---|
| 346 | <pre>
|
|---|
| 347 | return $.data[pixel];
|
|---|
| 348 | </pre>
|
|---|
| 349 |
|
|---|
| 350 | <H3>Editor 2 (main)</H3>
|
|---|
| 351 | <I>main</I> should return extracted data per pixel. As <I>proc</I> it can
|
|---|
| 352 | return a single array or an array with up to four sub-arrays each with
|
|---|
| 353 | numPix entries. They are displayed in the camera displays. The function
|
|---|
| 354 | implemented as <I>proc</I> is accessible as <I>proc(i)</I> with <I>i</I>
|
|---|
| 355 | being available in <I>proc</I> as <I>pixel</I>. A very simple extractor
|
|---|
| 356 | could be to return just the sample at the trigger position
|
|---|
| 357 | <pre>
|
|---|
| 358 | var rc = [];
|
|---|
| 359 | for (var i=0; i<$.event.numPix; i++)
|
|---|
| 360 | rc[i] = $.data[i][60];
|
|---|
| 361 | return rc;
|
|---|
| 362 | </pre>
|
|---|
| 363 | or taking the data pre-procesed by the code of the <I>proc</I>-function:
|
|---|
| 364 | <pre>
|
|---|
| 365 | var rc = [];
|
|---|
| 366 | for (var i=0; i<$.event.numPix; i++)
|
|---|
| 367 | rc[i] = proc(i)[60];
|
|---|
| 368 | return rc;
|
|---|
| 369 | </pre>
|
|---|
| 370 |
|
|---|
| 371 | Note that the precise access to the result of proc might depend on what
|
|---|
| 372 | exactly is retruned by proc (an array, or an array with sub-arrays).
|
|---|
| 373 |
|
|---|
| 374 | Pixel which are not returned (<tt>undefind</tt> or <tt>null</tt>) are
|
|---|
| 375 | not displayed. This allows to show cleaned images as well or test
|
|---|
| 376 | image cleaning algorithms.
|
|---|
| 377 |
|
|---|
| 378 | <H3>What is the data?</H3>
|
|---|
| 379 | The data are all data files found in disks in La Palma (to be precise:
|
|---|
| 380 | on daq's disks). The data is raw-data but with the most recent
|
|---|
| 381 | DRS calibration (only the 1024-cell offset calibration)
|
|---|
| 382 | applied, while the application is done in intergers, i.e. the
|
|---|
| 383 | fractional part of the calibration constant is removed.
|
|---|
| 384 | (This is basically what is written in our FITS files as part of the
|
|---|
| 385 | lossless compression process). No spike or jump removal is applied.
|
|---|
| 386 |
|
|---|
| 387 | <H3>The editor</H3>
|
|---|
| 388 | Key bindings of the editor can be found at
|
|---|
| 389 | <A HREF="http://codemirror.net/doc/manual.html#commands">Codemirror</A>.
|
|---|
| 390 | In addition the following binding are defined: Tab - Auto indent;
|
|---|
| 391 | F11 - Switch to fullscreen; Esc - In fullscreen mode to
|
|---|
| 392 | leave fullscreen; Ctrl-r - replace; Ctrl-y - Delete the line under the cursor;
|
|---|
| 393 | Ctrl-. (dot) - Fold code; Ctrl-Down (cursor down) - Autocomplete.
|
|---|
| 394 |
|
|---|
| 395 | <H3>How to change the file?</H3>
|
|---|
| 396 | Start typing the date in the filename field. The available files
|
|---|
| 397 | will be filtered as you type. To select a file you need to select
|
|---|
| 398 | it fom the pull down.
|
|---|
| 399 |
|
|---|
| 400 | <H3>How to change the displayed pixel?</H3>
|
|---|
| 401 | Enter the pixel number on the corresponding field or its hwardware
|
|---|
| 402 | address. As soon as you acknowledge your change (e.g. remove focus
|
|---|
| 403 | by clicking somewhere else) the pixel contents gets displayed.
|
|---|
| 404 |
|
|---|
| 405 | <H3>How to Save/Load a script?</H3>
|
|---|
| 406 | To load a file choose a file fro your local hard drive via the
|
|---|
| 407 | file selection dialog. To save the contents of the editor, press
|
|---|
| 408 | Save.
|
|---|
| 409 |
|
|---|
| 410 | <H3>Submit</H3>
|
|---|
| 411 | If you have changed the script and you want to run it on the current event
|
|---|
| 412 | press Submit. The Javascript will be executed for this event on
|
|---|
| 413 | the server.
|
|---|
| 414 |
|
|---|
| 415 | <!--<H3>Autosubmit</H3>
|
|---|
| 416 | If Autosumit is enabled, the script will be submitted each time
|
|---|
| 417 | the file name or the event number is changed and executed.-->
|
|---|
| 418 |
|
|---|
| 419 | <H3>Pixel value</H3>
|
|---|
| 420 | To display the value returned for a pixel just click on the pixel.
|
|---|
| 421 | The value will be displayed in the Pixel field. This will also
|
|---|
| 422 | display the corresponding waveform in the graph.
|
|---|
| 423 |
|
|---|
| 424 | <H3>Min/max values</H3>
|
|---|
| 425 | Min and max values for the plot and the graph can be determined
|
|---|
| 426 | automatically or manully. To set the to a fixed value, enable the
|
|---|
| 427 | min and/or max field and enter the value of your choice. It will
|
|---|
| 428 | survive changing files, events or pixel.
|
|---|
| 429 |
|
|---|
| 430 | <H3>Why is loading the page so slow?</H3>
|
|---|
| 431 | The total contents of the javascript libraries is about 1MB which
|
|---|
| 432 | all have to be treasferred to the browser. In addition the loading
|
|---|
| 433 | and processing of the event takes up to 1s so that the loading
|
|---|
| 434 | time of the page might be untypically slow. Once finished,
|
|---|
| 435 | the amaount of code to load can be decreased.
|
|---|
| 436 |
|
|---|
| 437 | <H3>How to unzoom the plot?</H3>
|
|---|
| 438 | Double click on the plot.
