Warning: symlink(): Permission denied in tripal_jbrowse_mgmt_copy_file() (line 440 of /var/www/html/sites/all/modules/tripal_jbrowse/tripal_jbrowse_mgmt/includes/tripal_jbrowse_mgmt.api.inc).

这是一个警告信息,指出在 `tripal_jbrowse_mgmt_copy_file()` 函数的实现中发生了 `symlink()` 函数的权限被拒绝的错误。这是在 `/var/www/html/sites/all/modules/tripal_jbrowse/tripal_jbrowse_mgmt/includes/tripal_jbrowse_mgmt.api.inc` 文件的第 440 行。
错误信息还指出,在将文件 `/var/www/html/sites/default/files/raw/pame.bam/ngs.bam/pame.ngs.bam` 复制到 `/var/www/html/sites/default/files/jbrowse/persea_americana__avocados/data/bam` 目录时失败。如果预期通过现有文件来创建此轨道,请选择 Symbolic Link(符号链接)选项。
这个错误可能是由于权限问题导致的。可能是文件或目录的权限设置不允许创建符号链接,或者执行该操作的用户没有足够的权限。你可能需要检查相关文件和目录的权限设置,并确保执行操作的用户具有足够的权限来创建符号链接或复制文件。
请注意,这只是一个警告信息,可能会影响到 JBrowse 扩展模块的功能。为了解决此问题,你需要检查并解决权限问题,并在需要时选择正确的选项来创建轨道。

使用std::filesystem::recursive_directory_iterator和std::filesystem::directory_options::follow_directory_symlink选项迭代目录
在C++标准库 `<filesystem>` 中,`std::filesystem::recursive_directory_iterator` 和 `std::filesystem::directory_options::follow_directory_symlink` 是一起使用的,用于递归地遍历目录,并且可以跟随符号链接。
当你创建一个 `recursive_directory_iterator` 对象时,你可以提供一个 `std::filesystem::directory_options` 实例,其中可以设置 `follow_directory_symlinks` 选项为 `true` 来表示跟随符号链接。这将允许你在遍历目录结构时,不仅包括直接的子目录,也包括通过符号链接指向的子目录。
以下是基本的用法示例:
```cpp
#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
void traverse_dir(const fs::path& root_path) {
fs::directory_options options;
options.recursive(); // 设置为递归模式
options.follow_directory_symlinks(); // 跟随符号链接
for (const auto &entry : fs::directory_iterator(root_path, options)) {
if (fs::is_directory(entry)) {
std::cout << "Directory: " << entry.path() << '\n';
} else {
std::cout << "File: " << entry.path() << '\n';
}
}
}
int main() {
traverse_dir(fs::current_path()); // 从当前工作目录开始
return 0;
}
```
在这个示例中,`traverse_dir` 函数会遍历指定路径下的所有目录,无论它们是否是符号链接,以及链接指向的是另一个目录还是文件。
Error: EACCES: permission denied, symlink
This error message means that the user running the command does not have permission to create a symlink (symbolic link) in the specified location.
To fix this issue, first ensure that you have the necessary permissions to create a symlink in the directory you are trying to create it in. You may need to check the file permissions using the `ls -l` command and change them using `chmod`.
If you do not have permission to create a symlink in the current directory, try creating it in a different directory where you have the necessary permissions.
Alternatively, you can try running the command with elevated permissions using `sudo` or as the root user. However, be cautious when using elevated permissions and only use them when necessary.
