DebugBreak equivalent in Java?

眉间皱痕 提交于 2019-12-06 19:23:05
问题 I'm looking for a way to break into the debugger from Java code, without setting a breakpoint in the IDE. In Win32 there was DebugBreak() , in C# there's DebugBreak() Equivalent in C#, but I can't find anything in Java. What I'm trying to do: say I have a wait with a 30s timeout, but in normal conditions that wait should always be <1s. I'd like to use ByteMan or something similar to wait with 1s timeout first, and break into the debugger if that wait timed out. 回答1: Not a direct answer to

How to set a breakpoint at a lambda call in Google Chrome DevTools?

随声附和 提交于 2019-12-06 19:04:53
问题 I use Babel and Google Chrome Developer Tools with JavaScript source maps enabled. Given this code function myFunc(elements) { return elements .map(element => element.value) .filter(value => value >= 0); } how can I pause execution at execution of lambda function element => element.value ? If I set a breakpoint at line of .map(element => element.value) it will only pause when map is executed, but not when the lambda function is executed. 回答1: This feature is finally available (at least in

How get a breakpoint on variable write in Visual Studio?

问题 How I can set breakpoint on variable change (I think this is write access) in Visual Studio? 回答1: This is referred to as a Data Breakpoint in Visual Studio. To create one you'll need the address of the variable in question (just add &variableName ) to the watch or immediate window. Then do the following Debug -> New Breakpoint -> New Data Breakpoint Enter the address in and size of the value in bytes Note: This is only supported for C++ applications. Managed languages don't support data break

Eclipse stops at non-existent breakpoint

问题 I have an Eclipse (java) project which stops at non-existent breakpoints. There was a breakpoint at this location at one time, but I removed it. Any ideas why this would be happening? Note: It is not the same issue mentioned here - phantom breakpoint driving me crazy! 回答1: If you are sure that there aren't breakpoints (Run > Remove All Breakpoints), then there are 2 things to consider: You are misunderstanding something of how the debugger works. Your program is stopped because it's waiting

Is there any way to break on the next line of code executed in Visual Studio?

问题 I'm trying to track down a bug that occurs when I click a particular element on an aspx page... In the past I've had to track down the class that handles that particular event and put a break point on the line that I think should be hit. Often it takes me several tries before I finally find the correct class....especially if the class is a user control buried somewhere... So it's left me wondering if there is any way to get Visual Studio to break at the next line of code executed after I

Cannot get rid of breakpoint in JdbcOdbcDriver.finalize()

∥☆過路亽.° 提交于 2019-12-06 15:41:19
I use MyEclipse 8.6 + Apache Tomcat 5.5.27 + JRockit 1.6.0 05 for web development. Every time I start up Tomcat in debug mode from MyEclipse, it suspends on a NullPointerException in JdbcOdbcDriver.finalize():96" . The stack trace is only Thread.run (of course, finalizer): protected synchronized void finalize() { if (OdbcApi.getTracer().isTracing()) { OdbcApi.getTracer().trace("Driver.finalize"); } try { if (hDbc != 0L) { disconnect(hDbc); closeConnection(hDbc); hDbc = 0L; } } catch (SQLException localSQLException) {} } It is really annoying, seeing this hundreds of times every workday. I did

How can gdb be used to watch for any changes in an entire region of memory?

China☆狼群 提交于 2019-12-06 11:57:46
For example, can I break on any change to memory in an address range from <startaddress> to <endaddress> ? How about reads and/or writes? On Linux/x86, GDB uses the processor debug registers to implement hardware watchpoints. Such watchpoints are fast -- the program runs at full speed, until the processor stops and signals the application when the access or write watchpoint is triggered. But such watchpoints can only work on 1-word sized data. Recent Valgrind versions (SVN, but no released versions) implement GDB remote protocol stub, and allow you to set read or write watchpoints over

Setting breakpoints dynamically at runtime in Javascript

99封情书 提交于 2019-12-06 11:51:42
Both firebug and the built in console in webkit browsers make it possible to set breakpoints in running Javascript code, so you can debug it as you would with any other language. What I'm wondering is if there is any way that I can instruct firebug or webkit that I'd like to set a breakpoint on line X in file Y at runtime, and to be able to examine variables in the specific scope that I have paused in. I need something that can work in both Chrome (or any other webkit browser) and Firefox. For the latter Firebug is an acceptable dependency. Supporting IE is not a requirement. I've been

XCode Global Breakpoints don't show stack trace

问题 I set up global break points from locations libobjc.A.dylib and CoreFoundation. I run my iphone app and it hits the exception. XCode stops at the breakpoint but does not show any error in the log besides: Pending breakpoint 1 - "objc_exception_throw" resolved Pending breakpoint 2 - "-[NSException raise]" resolved I click the "Continue" button on the console and I get the same indistinguishable error I received before I enabled the breakpoints. How do I get the stack trace that setting up the

Debugging of a JVM application (Java or Scala) with breakpoints in Gradle and IntelliJ 2016.3.5

I have a JVM application that I need to debug using breakpoints with a Gradle task (run and test as dependencies) within IntelliJ 2016.3.5. There are various sources on how to accomplish debugging with Gradle and IntelliJ: Debug Gradle plugins with IntelliJ Using Intellij to set breakpoints in gradle project (most helpful one) https://youtrack.jetbrains.com/issue/IDEA-119551 https://youtrack.jetbrains.com/issue/IDEA-86465 https://youtrack.jetbrains.com/issue/IDEA-119494 However, these sources are either outdated or meant for another scenario. I do not want to debug the Gradle script but the
