| 26 | * eventHandler |
| 27 | * |
| 28 | * This module handles events as they come in directly from JVMTI |
| 29 | * and also maps them to JDI events. JDI events are those requested |
| 30 | * at the JDI or JDWP level and seen on those levels. Mapping is |
| 31 | * one-to-many, a JVMTI event may map to several JDI events, or |
| 32 | * to none. Part of that mapping process is filteration, which |
| 33 | * eventFilter sub-module handles. A JDI EventRequest corresponds |
| 34 | * to a HandlerNode and a JDI filter to the hidden HandlerNode data |
| 35 | * used by eventFilter. For example, if at the JDI level the user |
| 36 | * executed: |
| 37 | * |
| 38 | * EventRequestManager erm = vm.eventRequestManager(); |
| 39 | * BreakpointRequest bp = erm.createBreakpointRequest(); |
| 40 | * bp.enable(); |
| 41 | * ClassPrepareRequest req = erm.createClassPrepareRequest(); |
| 42 | * req.enable(); |
| 43 | * req = erm.createClassPrepareRequest(); |
| 44 | * req.addClassFilter("Foo*"); |
| 45 | * req.enable(); |
| 46 | * |
| 47 | * Three handlers would be created, the first with a LocationOnly |
| 48 | * filter and the last with a ClassMatch filter. |
| 49 | * When a JVMTI class prepare event for "Foobar" |
| 50 | * comes in, the second handler will create one JDI event, the |
| 51 | * third handler will compare the class signature, and since |
| 52 | * it matchs create a second event. There may also be internal |
| 53 | * events as there are in this case, one created by the front-end |
| 54 | * and one by the back-end. |
| 55 | * |
| 56 | * Each event kind has a handler chain, which is a doublely linked |
| 57 | * list of handlers for that kind of event. |

| 273 | * is always reported last. Here are the possible combinations and |
| 274 | * their order: |
| 275 | * |
| 276 | * (p1) METHOD_ENTRY, BREAKPOINT (existing) |
| 277 | * (p2) METHOD_ENTRY, BREAKPOINT (new) |
| 278 | * (p1) METHOD_ENTRY, SINGLE_STEP |
| 279 | * (p1) METHOD_ENTRY, SINGLE_STEP, BREAKPOINT (existing) |
| 280 | * (p1/p2) METHOD_ENTRY, SINGLE_STEP, BREAKPOINT (new) |
| 281 | * (p1) SINGLE_STEP, BREAKPOINT (existing) |
| 282 | * (p2) SINGLE_STEP, BREAKPOINT (new) |
| 283 | * |
| 284 | * BREAKPOINT (existing) indicates a BREAKPOINT that is set before |
| 285 | * the other co-located event is posted. BREAKPOINT (new) indicates |
| 286 | * a BREAKPOINT that is set after the other co-located event is |
| 287 | * posted and before the thread has resumed execution. |
| 288 | * |
| 289 | * Co-location of events policy used to be implemented via |
| 290 | * temporary BREAKPOINTs along with deferring the reporting of |
| 291 | * non-BREAKPOINT co-located events, but the temporary BREAKPOINTs |
| 292 | * caused performance problems on VMs where setting or clearing |
| 293 | * BREAKPOINTs is expensive, e.g., HotSpot. |
| 294 | * |
| 295 | * The policy is now implemented in two phases. Phase 1: when a |
| 296 | * METHOD_ENTRY or SINGLE_STEP event is received, if there is an |
| 297 | * existing co-located BREAKPOINT, then the current event is |
| 298 | * deferred. When the BREAKPOINT event is processed, the event |
| 299 | * bag will contain the deferred METHOD_ENTRY and/or SINGLE_STEP |
| 300 | * events along with the BREAKPOINT event. For a METHOD_ENTRY |
| 301 | * event where there is not an existing co-located BREAKPOINT, |
| 302 | * if SINGLE_STEP events are also enabled for the thread, then |
| 303 | * the METHOD_ENTRY event is deferred. When the SINGLE_STEP event |
| 304 | * is processed, the event bag will also contain the deferred |
| 305 | * METHOD_ENTRY event. This covers each of the combinations |
| 306 | * marked with 'p1' above. |
| 307 | * |
| 308 | * Phase 2: if there is no existing co-located BREAKPOINT, then the |
| 309 | * location information for the METHOD_ENTRY or SINGLE_STEP event |
| 310 | * is recorded in the ThreadNode. If the next event for the thread |
| 311 | * is a co-located BREAKPOINT, then the first BREAKPOINT event will |
| 312 | * be skipped since it cannot be delivered in the same event set. |
| 313 | * This covers each of the combinations marked with 'p2' above. |
| 314 | * |
| 315 | * For the combination marked p1/p2, part of the case is handled |
| 316 | * during phase 1 and the rest is handled during phase 2. |
| 317 | * |
| 318 | * The recording of information in the ThreadNode is handled in |
| 319 | * this routine. The special handling of the next event for the |
| 320 | * thread is handled in skipEventReport(). |
