NetBeans调试不进入断点 5C

RedHat Enterprise Linux 6, C++ NetBeans下写的程序,主要是在main线程中创建了2个子线程,其中一个用libpcap来抓包并把包存到一个队列里,另一个线程是不断从队列里取包,利用pcap_dump方法存到.pcap文件里。现在程序遇到了几个问题:

调试的时候在每个线程处都打了断点,开始debug的时候都能进去断点,但是点continue后就进不去任何断点了,也没有在存数据,日志也没在记,那么这个时候程序运行到哪儿了呢?应该没有死锁,也没抛异常,因为在catch异常的地方也打了断点;
发现在Linux C++程序一直运行一段时间,在数据量大时总是很容易出现terminate called after throwing an instance of std bad_alloc what():std::bad_alloc的错误,请问这是因为指针new和delete的时候没用好导致的吗,但好像也有人说频繁new和delete也会出现这种问题。
楼主C++不是很好,现在工作中总要用C++,而且同事也没有对Linux C++很熟悉的,所以还请懂的大神指点一二,多谢了。

Netbeans 8.0.2调试器断点不起作用

<div class="post-text" itemprop="text"> <p>I just installed Netbeans for PHP (version 8.0.2). XDebug seemed to come with this installation. I'm trying to get the breakpoints and stepping through the code to work on my local machine, which is running WAMP, to work.</p> <p>I've never used debugging for PHP; only with Excel VBA, so I'm familiar with how breakpoints and stepping through code works. It seems that this feature comes with Netbeans/XDebug.</p> <p>But when I click on the debug button on the top middle of the screen, a bunch of buttons pop up. A good portion of them are greyed out and I am not able to use them. Specifically, the continue, step over, step into, step out, and run to cursor. The stop button is there, but works fine. When I click on debug, a new browser window opens and my code displays in the browser. It seems to ignore the breakpoint that I have placed in my code, though.</p> <p>I have breakpoints in my code, just to see how it all works in a PHP IDE, but I can't seem to get the breakpoints to work. My code is really nothing fancy; all I have is what is below:</p> <pre><code>&lt;?php echo "Hello world!&lt;br /&gt;"; echo "Google Chromium."; </code></pre> <p>I have a breakpoint on line 2 where it says "Hello world!" (I clicked on the left side of the code and a red box displayed next to the line of code).</p> <p>I am not really sure where to start with fixing this. XDebug shows up in my <code>phpinfo()</code> as version 2.2.5. I've seen some questions address changing some of the parameters in php.ini, but each seems very specific to the person who posts problem. I've checked the port to make sure it's 9000, I've also placed/changed the following code in my php.ini file:</p> <pre><code>[xdebug] xdebug.remote_enable = on xdebug.profiler_enable = on xdebug.profiler_enable_trigger = off xdebug.profiler_output_name = cachegrind.out.%t.%p xdebug.profiler_output_dir = "c:/wamp/tmp" xdebug.show_local_vars=0 xdebug.remote_handler=dbgp xdebug.remote_host=localhost xdebug.remote_port=9000 </code></pre> <p>How do I get breakpoints to work and stepping through code to work with Netbeans and XDebug?</p> </div>

Netbeans断点不与xdebug一起使用

<div class="post-text" itemprop="text"> <p>Right i'm pulling my hair out on this one. </p> <p>I'm using Netbeans, EasyPHP, and Installed xdebug using by copy/pasting my phpinfo() results into the xdebug wizard which then tells you which .dll file you need to download.</p> <p>Well i've followed all the instructions, my phpinfo() now says xdebug is installed, I've added the appropiate lines in my php.ini file. However, my breakpoints in Netbeans do not work! I know that xdebug is installed because if I manually add <code>xdebug_break()</code> to my code then they act as a breakpoint.</p> <p>How can I get netbeans and breakpoints to work without manually using the xdebug php function everytime ?!</p> <p>PS. I know this question has been asked a million times but I've followed the other solutions and none have fixed my problem!</p> <p>I'm using XP if that shines any light on the matter?</p> </div>

在Netbeans远程服务器上进行调试

<div class="post-text" itemprop="text"> <p>I use Netbeans and debug code with xdebug for debugging php files that are remote from server. And I config to upload to the server when I save a file in Netbeans.</p> <p>I work in a team. I download some code that needs to be modified or added. So in Netbeans (in my computer) there are some old files that aren't updated from the server which is caused by people on the team who modified or added files in server.</p> <p>Example: Server has files <code>index.php</code> , <code>foo.php</code> , <code>bar.php</code> and my Netbeans has files <code>index.php</code> , <code>foo.php</code> , <code>bar.php</code> too, but <code>bar.php</code> in the server is updated by people on the team. But <code>bar.php</code> in my Netbeans is old file that isn't updated. So <code>bar.php</code> file in server is the newest <code>bar.php</code> in my Netbeans</p> <p>And code in <code>foo.php</code> calls function from <code>bar.php</code></p> <p><strong>Question</strong> If I am debugging in <code>foo.php</code> file. </p> <p>1) Netbean will upload <code>foo.php</code> file to server or not.</p> <p>2) Netbean will upload all files (in Netbeans) to server or not.</p> <p>3) If Answer 1) and 2) is not.

<div class="post-text" itemprop="text"> <p>I've been using netbeans 8.2 for several self-contained Drupal sites.

NetBeans + XDebug断点无法正常工作

<div class="post-text" itemprop="text"> <p>I know there are countless of questions regarding this subject, however no matter what I've tried I've had no luck whatsoever. The problem I'm encountering is regarding breakpoints when using NetBeans and XDebug (on Windows 8.1 if that affects anything).</p> <p>The issue is that no breakpoints are working. By default when debugging with NetBeans, it stops on the first line and this does successfully happen. Therefore NetBeans is somehow connecting to XDebug. However, any other breakpoints in any other files are not working.</p> <p>I've tried various different settings in the php.ini file but no luck so far. I've also tried switching on the XDebug log file so that maybe I can analyse what's going on, but this also didn't work. Finally I've tried setting breakpoints using <code>xdebug_break()</code> which also didn't work.</p> <p><strong>XDebug settings in php.ini</strong></p> <pre><code>;[XDebug] ; Only Zend OR (!)

PHP Xdebug Netbeans断点

<div class="post-text" itemprop="text"> <p>After working fine, with no config changes for months xdebug/netbeans is now useless. I can create breakpoints but whenever it has 'stepped in' to a further scope its impossible to step thru and simply jumps out of the inner scope to the caller. There are no exceptions generated.</p> <p>Using tail -f xdebug.log shows breakbpoints being correctly created / removed, Netbeans failed to remove from Ubuntu Software Centre, however I reinstalled over the top of existing. This does not seem clean as Netbeans remembered settings.</p> <h2>Latest steps:</h2> <p>Ran instructions at <a href="https://xdebug.org/wizard.php" rel="nofollow noreferrer">https://xdebug.org/wizard.php</a> and rebooted webserver Of note here it recommended install of xdebug-2.4.1 instead of previously 2.4.0 however this made no difference to current state of NetB / Xdebug combo. I checked php-fpm ini and this correct phpized version still ?</p> <p>Ran uninstall.sh at /usr/local/netbeans8.*</p> <p>Downloaded re-install at <a href="http://www.oracle.com/technetwork/articles/javase/jdk-netbeans-jsp-142931.html" rel="nofollow noreferrer">http://www.oracle.com/technetwork/articles/javase/jdk-netbeans-jsp-142931.html</a> (I also need Java JDK so this is ideal) Made it executable and ran installer (as sudo)</p> <pre><code>chmod +x jdk-8u101-nb-8_1-linux-x64.sh; ./jdk-8u101-nb-8_1-linux-x64.sh; </code></pre> <p>And nothing changes - this is very frustrating that software designers still cannot be a***d to create proper uninstallers. Still same settings prior to re-install.</p> <h2>Further</h2> <p>Closed NetBeans again</p> <pre><code>cdl /home </code></pre> <p>then check in each user dir</p> <pre><code>rm -r .netbeans rm -r NetBeansProjects </code></pre> <p>There was also a directory called nbproject near the site root directory and in the sitefiles repo which is gitted - these was removed.</p> <h2>Update</h2> <p>Now set up the project including the crap Netbeans debug 'stop at first line' and allowing watches (whats the point of these defaults in a generally used framework norm such as laravel and what is debugging without being able to look at variable values). Its now begun allowing stepping thru code but after closing debug session will now not allow access to run config. Had to close all projects and reopen. This proves that its a Netbeans issue.</p> </div>
