问题 I can't debug (simple run works fine) my unit tests. Squeryl fails with the following exception: error while reflecting on metadata for (Some(private scala.Option com.company.play.model.db.mapping.Position.orgUnit2id),Some(public scala.Option com.company.play.model.db.mapping.Position.orgUnit2id()),None,Set(@org.squeryl.annotations.ColumnBase(optionType=class java.lang.Object, name=, length=-1, scale=-1, value=ORG_UNIT2ID))) of class com.company.play.model.db.mapping.Position java.lang

问题 I have a script written in Pascal. I would to debug it in this way: stop at every line, dump values of all variables in memory and go to the next line. Is it possible to do it with gdb or some other open-source tool for Linux? 回答1: Compile file with option -g : fpc/gpc -g file.pas Run gdb for this file: gdb file Set all of needed variables: display first_var display second_var ... Start debugging: start By pressing s you can continue to the next line. 回答2: I'll present a proof-of-concept that

问题 Sometimes when I am debugging I get message like this. Program received signal SIG44, Real-time event 44. What does it means? Thank you. EDIT : Platform is linux 回答1: A signal is a message sent by the kernel to a process in order to notify the process that event of some kind has occurred in the system. Usual signals on linux are for example SIGINT (value 2, interrupt from keyboard) or SIGKILL ( value 9, kill a program). Signals are received either when the kernel detects a system event (like

问题 Unity 5.1.2 iOS 8.4 Ive noticed massive performance issues with iPhone 6 Plus Tested on iPhones 4s, 5, 6 performance looks about that Running solid 60 FPS On iPhone 6 Plus however performance is going down to about 22 FPS for some reason.
