| 247 | * s = TraceKit.computeStackTrace.ofCaller([depth]) | | |
| 248 | * s = TraceKit.computeStackTrace(exception) // consider using TraceKit.report instead (see below) | | |
| 249 | * Returns: | | |
| 250 | * s.name - exception name | | |
| 251 | * s.message - exception message | | |
| 252 | * s.stack[i].url - JavaScript or HTML file URL | | |
| 253 | * s.stack[i].func - function name, or empty for anonymous functions (if guessing did not work) | | |
| 254 | * s.stack[i].args - arguments passed to the function, if known | | |
| 255 | * s.stack[i].line - line number, if known | | |
| 256 | * s.stack[i].column - column number, if known | | |
| 257 | * s.stack[i].context - an array of source code lines; the middle element corresponds to the correct line# | | |
| 258 | * s.mode - 'stack', 'stacktrace', 'multiline', 'callers', 'onerror', or 'failed' -- method used to collect the stack trace | | |
| 259 | * | | |
| 260 | * Supports: | | |
| 261 | * - Firefox: full stack trace with line numbers and unreliable column | | |
| 262 | * number on top frame | | |
| 263 | * - Opera 10: full stack trace with line and column numbers | | |
| 264 | * - Opera 9-: full stack trace with line numbers | | |
| 265 | * - Chrome: full stack trace with line and column numbers | | |
| 266 | * - Safari: line and column number for the topmost stacktrace element | | |
| 267 | * only | | |
| 268 | * - IE: no line numbers whatsoever | | |
| 269 | * | | |
| 270 | * Tries to guess names of anonymous functions by looking for assignments | | |
| 271 | * in the source code. In IE and Safari, we have to guess source file names | | |
| 272 | * by searching for function bodies inside all page scripts. This will not | | |
| 273 | * work for scripts that are loaded cross-domain. | | |
| 274 | * Here be dragons: some function names may be guessed incorrectly, and | | |
| 275 | * duplicate functions may be mismatched. | | |
| 276 | * | | |
| 277 | * TraceKit.computeStackTrace should only be used for tracing purposes. | | |
| 278 | * Logging of unhandled exceptions should be done with TraceKit.report, | | |
| 279 | * which builds on top of TraceKit.computeStackTrace and provides better | | |
| 280 | * IE support by utilizing the window.onerror event to retrieve information | | |
| 281 | * about the top of the stack. | | |
| 282 | * | | |
| 283 | * Note: In IE and Safari, no stack trace is recorded on the Error object, | | |
| 284 | * so computeStackTrace instead walks its *own* chain of callers. | | |
| 285 | * This means that: | | |
| 286 | * * in Safari, some methods may be missing from the stack trace; | | |
| 287 | * * in IE, the topmost function in the stack trace will always be the | | |
| 288 | * caller of computeStackTrace. | | |
| 289 | * | | |
| 290 | * This is okay for tracing (because you are likely to be calling | | |
| 291 | * computeStackTrace from the function you want to be the topmost element | | |
| 292 | * of the stack trace anyway), but not okay for logging unhandled | | |
| 293 | * exceptions (because your catch block will likely be far away from the | | |
| 294 | * inner function that actually caused the exception). | | |
| 295 | * | | |
| 296 | * Tracing example: | | |
| 297 | * function trace(message) { | | |
| 298 | * var stackInfo = TraceKit.computeStackTrace.ofCaller(); | | |
| 299 | * var data = message + "\n"; | | |
| 300 | * for(var i in stackInfo.stack) { | | |
| 301 | * var item = stackInfo.stack[i]; | | |
| 302 | * data += (item.func || '[anonymous]') + "() in " + item.url + ":" + (item.line || '0') + "\n"; | | |
| 303 | * } | | |
| 304 | * if (window.console) | | |
| 305 | * console.info(data); | | |
