Console is not supported for a recorded stack frame, in debug mode

问题 I am not able to backtrace using the bt command in debug mode after crash. I have searched but did not get the solution. I have tried [NSThread callStackSymbols] , but it gives the same message in console: Console is not supported for a recorded stack frame How can I do this? 回答1: There's nothing wrong with your Xcode, you just need to select the appropriate instance from the debug navigator, like this.

PHP: friend classes and ungreedy caller function/class

由 喜夏-厌秋 提交于 2020-01-22 16:27:31
问题 Is there any way to get the caller function with something else than debug_backtrace()? I'm looking for a less greedy way to simulate scopes like friend or internal . Let's say I have a class A and a class B. Until now, I've been using debug_backtrace() , which is too greedy (IMHO). I thought of something like this: <?php class A { public function __construct(B $callerObj) {} } class B { public function someMethod() { $obj = new A($this); } } ?> It might be OK if you want to limit it to one

Is debug_backtrace() safe for serious usage in production environment?

问题 It's functionality is so strong that I worry about its stability and performance. What do you think? UPDATE What I'm doing is this: $old_dir = getcwd(); chdir( dirname($included_file) ); include ( $included_file ); chdir( $old_dir ); Essentially it just does include ( $included_file ); ,but inside that $included_file it can't find 3.php which is in the same directory as itself is in,so I manually set the cwd and it works.But it would be nice if I find the reason why it can't find.As for why

Kernel oops Oops: 80000005 on arm embedded system

问题 Please help me to solve this Oops. I use a 1 milli sec high resolution timer and installing it as a seperate module with "insmod". This fires every 1 ms and i have to do some task with this timer interrupt. There are other processes which does image transfer and i see ethernet driver interrupt appearing to send the image. This enet interrupt is having some high priority and looks like it is delaying the 1 ms timer interrupt above, but i am not sure. I see the below Oops after running test for

Enable full backtrace-logging in production

由 纵然是瞬间 提交于 2019-12-11 03:52:41
问题 I am getting an error only in production and to debug that, I would like to enable full backtracing in production. I already have config.log_level = :debug in config/environments/production.rb , but that does not give me a backtrace, only logs the queries, requests and and served assets in detail. 回答1: To show backtraces in the production environment, set config.consider_all_requests_local = true in config/environments/production.rb . It's not good practice to leave this turned on, however it

debug_backtrace() from registered shutdown function in PHP

由 こ雲淡風輕ζ 提交于 2019-11-29 01:11:42
While tinkering for an answer to this question , I found that debug_backtrace() doesn't trace beyond the function registered to register_shutdown_function() , when called from within it. This was mentioned in this comment for register_shutdown_function() in the PHP docs, stating: You may get the idea to call debug_backtrace or debug_print_backtrace from inside a shutdown function, to trace where a fatal error occurred. Unfortunately, these functions will not work inside a shutdown function. Explained with a bit more detail, comments on this answer state: Doesn't work. The shutdown function
