289 // possible that the error handler itself may crash or die on an internal | |
290 // error, for example, when the stack/heap is badly damaged. We must be | |
291 // able to handle recursive errors that happen inside error handler. | |
292 // | |
293 // Error reporting is done in several steps. If a crash or internal error | |
294 // occurred when reporting an error, the nested signal/exception handler | |
295 // can skip steps that are already (or partially) done. Error reporting will | |
296 // continue from the next step. This allows us to retrieve and print | |
297 // information that may be unsafe to get after a fatal error. If it happens, | |
298 // you may find nested report_and_die() frames when you look at the stack | |
299 // in a debugger. | |
300 // | |
301 // In general, a hang in error handler is much worse than a crash or internal | |
302 // error, as it's harder to recover from a hang. Deadlock can happen if we | |
303 // try to grab a lock that is already owned by current thread, or if the | |
304 // owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the | |
305 // error handler and all the functions it called should avoid grabbing any | |
306 // lock. An important thing to notice is that memory allocation needs a lock. | |
307 // | |
308 // We should avoid using large stack allocated buffers. Many errors happen | |
309 // when stack space is already low. Making things even worse is that there | |
310 // could be nested report_and_die() calls on stack (see above). Only one | |
