|
275 |
// possible that the error handler itself may crash or die on an internal |
|
276 |
// error, for example, when the stack/heap is badly damaged. We must be |
|
277 |
// able to handle recursive errors that happen inside error handler. |
|
278 |
// |
|
279 |
// Error reporting is done in several steps. If a crash or internal error |
|
280 |
// occurred when reporting an error, the nested signal/exception handler |
|
281 |
// can skip steps that are already (or partially) done. Error reporting will |
|
282 |
// continue from the next step. This allows us to retrieve and print |
|
283 |
// information that may be unsafe to get after a fatal error. If it happens, |
|
284 |
// you may find nested report_and_die() frames when you look at the stack |

// in a debugger. |

// |
|
287 |
// In general, a hang in error handler is much worse than a crash or internal |
|
288 |
// error, as it's harder to recover from a hang. Deadlock can happen if we |
|
289 |
// try to grab a lock that is already owned by current thread, or if the |
|
290 |
// owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the |
|
291 |
// error handler and all the functions it called should avoid grabbing any |
|
292 |
// lock. An important thing to notice is that memory allocation needs a lock. |
|
293 |
// |
|
294 |
// We should avoid using large stack allocated buffers. Many errors happen |
|
295 |
// when stack space is already low. Making things even worse is that there |
|
296 |
// could be nested report_and_die() calls on stack (see above). Only one |
