In other words, it's PHP that isn't giving us the data rather than Sentry. ------------------------------------------------------------------------ [2018-04-26 23:02:57] hanskrentel at yahoo dot de you can do in PHP userland, at the beginning of your app (and before the error handler is triggered), reserve some memory (e.g. by assigning a larger string to a global variable), then when the error is triggered and w/ the problems you talk about, free that buffer. ------------------------------------------------------------------------ [2018-04-26 22:57:17] archon810 at gmail dot com Description: ------------ Hi, This is a follow-up directly with the PHP team regarding https://github.com/getsentry/sentry-php/issues/582, a Sentry issue about capturing variables and stack traces for PHP. The problem is, after certain fatal exceptions, like out of memory or maximum execution time exceeded, Sentry is unable to capture stack traces and variables. The conclusion in the thread is that error_get_last (http://php.net/manual/en/function.error-get-last.php) does not provide them to Sentry in such cases, so I'm here to facilitate a discussion around the subject and find a possible fix because it's extremely valuable to be able to see the variables and stack traces for such fatal failures. If the problem is that PHP's limitation, such as bumping into the memory max, prevents this extra info from being passed, perhaps we can introduce a configurable buffer which can help house this data? Please discuss. Thank you. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76274&edit=1
