breakpoints

When debugging ASP.NET MVC app, breakpoints are not hit

由 只愿长相守 提交于 2019-11-30 11:52:47
问题 When trying to debug a ASP.NET MVC app, the breakpoints in my controllers arent getting hit. When entering debug mode they just show an empty red circle with a warning triangle instead of the normal full circle. This is strange because debugging was working fine until now, and no configuration changes have been made in my environment for a while. I have seen this question and had a look at my modules view and the correct ones aren't being loaded, however I'm not sure how to remedy this. Also

LLDB Error: Unable to resolve breakpoint to any actual locations

由 谁都会走 提交于 2019-11-30 11:46:59
I'm trying to use LLDB (because I apparently can't use gdb anymore) to debug som of my code and each time I try to... (lldb) breakpoint set -f file.c -l 65 I get... Breakpoint 1: no locations (pending) WARNING: Unable to resolve breakpoint to any actual locations. I've tried different things like assigning the breakpoint to a function and such but I always get the same error. When running there's no break. Please help! lldb: resolving breakpoints to locations If your out file doesn't have debugging symbols enabled for Code Generation Options then breakpoints likely can't be resolved to

Why is my xcode jump to assembly view when break point set?

由 这一生的挚爱 提交于 2019-11-30 11:39:54
When I try to debug with breakpoint, it jump to assembly view like this no matter which line of code. I want the highlight of current source line back!! How can I config it?? This is a useful feature sometimes, but is easy to turn off: Debug > Debug Workflow > Always Show Disassembly In older versions of Xcode (<6.1): Product > Debug Workflow > Show Disassembly When Debugging I'm having the same issue in Xcode 6.1 and solved it by doing the following: Debug -> Debug Workflow -> UNCHECK Always Show Disassembly Make sure "Always Show Disassembly" is unchecked You can try this Product > Debug >

PHP Debugging with Breakpoints - case studies, examples..?

由 ≡放荡痞女 提交于 2019-11-30 11:28:15
I'd really like to get deeper into my php scripts and use things like breakpoints, as I'm doing with JS with firebug. I'd like to know more about what techniques people use, and some solid examples of how to debug with breakpoints a php project. Thing's I'd like to be able to see.. Properties of objects Class hierarchies.. where objects are coming from, file names etc.. (useful in ZF/Magento) Variables, types, content.. headers, post data, get data, session data, cookies.. Network / filesystem status.. I know a lot of this can be done with logging and print_r/vardump etc, but its a bit raw..

GDB breakpoints

由 浪尽此生 提交于 2019-11-30 11:21:44
问题 I have a list of breakpoints which I want to add each time I debug a particular program. Is there a way I can put all of the breakpoint information in a file and use it at the start of each debug session? In other words can I provide a script file with breakpoint information to GDB before I give the 'run' command? 回答1: From man gdb(1) : -x file Execute GDB commands from file file. You could then put your breakpoints in a file: break [file:]function break [file:]function ... 回答2: You can put

What is meant by a number after “break” or “continue” in PHP?

问题 Could someone please explain, with examples, what is meant by loop break 2 or continue 2 in PHP? What does it mean when break or continue is followed by a number? 回答1: $array = array(1,2,3); foreach ($array as $item){ if ($item == 2) { break; } echo $item; } outputs "1" because the loop was broken forever, before echo was able to print "2". $array = array(1,2,3); foreach ($array as $item){ if ($item == 2) { continue; } echo $item; } outputs 13 because the second iteration was passed $numbers

How to figure out proper min-width and max-width values for responsive CSS?

由 感情迁移 提交于 2019-11-30 10:15:44
I'm just now diving into responsive CSS and design, and I'm wondering how I'm supposed to figure out various device widths out. I don't want to spend all day testing every single mobile device possible, I just want to get the responsive layout enough to where it works. I saw some sites using @media only screen and (max-device-width: xx) but it seems that limits it to very specific resolutions, not actual browser window sizes. Any advice at all would be great. I'm not new to web development or CSS, but totally new to responsive design. It would seem that you're trying to figure out where and

Eclipse pausing without a breakpoint

由 旧巷老猫 提交于 2019-11-30 09:14:43
问题 While debugging my project in Eclipse, it will (repeatably, at the same point in the code) pause execution as if it's reached a breakpoint. No exceptions are thrown, the project has no breakpoints, and if I hit resume, it carries on without a problem. What could be causing this behaviour? 回答1: The Eclipse debugger pauses if the code throws an exception - at least it does for me (maybe this can be toggled). Just un-pause the thread and you'll most likely see a stacktrace being printed to

Using GDB without debugging symbols on x86?

由 我怕爱的太早我们不能终老 提交于 2019-11-30 08:26:48
How do I use GDB to debug a program which do not have debugging symbols on a 32-bit x86 processor? Inspecting the function arguments, local variables, resolving pointers would be useful to know how to do. The intention is not really to use this for reverse engineering, as I'm sometimes just too lazy to install the debugging symbols and would be great to know how to get some basic information out of gdb. To start out, you can do; gdb "whatever" break __libc_start_main r that will setup a breakpoint in libc's crt0 code and allow you to break before main, even if the target binary is totally

Debugging and counting breakpoint hits

由 穿精又带淫゛_ 提交于 2019-11-30 07:52:04
问题 Sometimes when I examine a code I didn’t write, I launch eclipse in debug mode and use figures to understand a program. For example, if they are n items retrieved from the DB, it can be interesting to know that there’re n processed items in a service, etc. When loops are used, things get more complicated: if we’re in a “while” loop, the number of execution is not defined and if there are alternatives, the flow of execution can greatly change. For this purpose, I sometimes set a breakpoint in
