344 | Libev contains numerous internal assert() invocations to check for |
|
|
345 | consistency and user errors. These are normally enabled, but most |
|
|
346 | perl builds disable this error reporting mechanism by default. You |
|
|
347 | can re-enable these asserts here. Enabling them might help you catch |
|
|
348 | programming bugs earlier, but might cause a small slowdown. Also, failures |
|
|
349 | will be reported by aboritng your program, instead of throwing a perl |
|
|
350 | exception. |
|
|
351 | |
|
|
352 | If unsure, enable this if you only use this perl installation for |
|
|
353 | development, and leave it off for use in production environments. |

366 | Very rarely, people want to tweak EV even more, e.g. to exclude |
|
|
367 | or include certain watcher types or backends. This can be done by adding |
|
|
368 | extra -D options here, or via the EV_EXTRA_DEFS environment variable. |
|
|
369 | |
|
|
370 | For example, if you run into compile problems because of missing memory |
|
|
371 | fences (or you just want extra performance), you can tell EV to not support |
|
|
372 | smp and threads via -DEV_NO_THREADS. |
