Eclipse/LiClipse 打开 .py 文件时冻结
Eclipse/LiClipse freezes when .py file is opened
我的带有 PyDev 的 LiClipse 在项目打开几秒钟后开始冻结。我检查了更新但没有成功。当它被冻结时，LiClipse 消耗了大约 48% 的 CPU 和 300 000 kb 的内存（消耗这么多内存可能还可以）。
编辑：当项目不是 运行 时冻结，它只是在 Eclipse 中打开！
我已经尝试删除 .metadata 并从头开始导入项目，但这个问题又出现了。
我怀疑当我打开一个特定的 py 文件时会发生这种冻结，其中有一个很长的字符串（我正在处理请求 - 帖子）。
这是一段来自 .metadata 的日志，但它可能不包含根据时间冻结的问题（最后记录的问题 - 15:56，最后一次冻结 - 15:58）：

可能是哪里出了问题？
不幸的是，日志似乎没有太大帮助（显示的条目应该是无害的）。
我认为你是对的，因为代码中可能存在某种模式，由于某种原因使其递归，所以，如果它是 public，你能否指出我，以便我可以尝试打开它就出现reproduce/fix的错误？
否则，另一种方法是在发生这种情况时将一些分析器附加到 Eclipse 并将输出传递给我（即：https://www.yourkit.com/ can attach to a running program if you pass some vmargs to eclipse.ini -- https://www.yourkit.com/docs/80/help/agent.jsp）
另一个选项可能是获取 Eclipse SDK、PyDev 源代码 (http://pydev.org/developers.html)，然后执行调试会话并按下调试器暂停键以查看可能发生的情况...
我的带有 PyDev 的 LiClipse 在项目打开几秒钟后开始冻结。我检查了更新但没有成功。当它被冻结时，LiClipse 消耗了大约 48% 的 CPU 和 300 000 kb 的内存（消耗这么多内存可能还可以）。

!ENTRY org.eclipse.egit.ui 2 0 2015-05-12 15:27:21.162
!MESSAGE Warning: EGit couldn't detect the installation path "gitPrefix" of native Git. Hence EGit can't respect system level
Git settings which might be configured in ${gitPrefix}/etc/gitconfig under the native Git installation directory.
The most important of these settings is core.autocrlf. Git for Windows by default sets this parameter to true in
this system level configuration. The Git installation location can be configured on the
Team > Git > Configuration preference page's 'System Settings' tab.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.
!ENTRY org.eclipse.egit.ui 2 0 2015-05-12 15:27:21.163
!MESSAGE Warning: The environment variable HOME is not set. The following directory will be used to store the Git
user global configuration and to define the default location to store repositories: 'C:\Users\Milwou'. If this is
not correct please set the HOME environment variable and restart Eclipse. Otherwise Git for Windows and
EGit might behave differently since they see different configuration options.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

可能是哪里出了问题？
不幸的是，日志似乎没有太大帮助（显示的条目应该是无害的）。
我认为你是对的，因为代码中可能存在某种模式，由于某种原因使其递归，所以，如果它是 public，你能否指出我，以便我可以尝试打开它就出现reproduce/fix的错误？
否则，另一种方法是在发生这种情况时将一些分析器附加到 Eclipse 并将输出传递给我（即：https://www.yourkit.com/ can attach to a running program if you pass some vmargs to eclipse.ini -- https://www.yourkit.com/docs/80/help/agent.jsp）
另一个选项可能是获取 Eclipse SDK、PyDev 源代码 (http://pydev.org/developers.html)，然后执行调试会话并按下调试器暂停键以查看可能发生的情况...
