DDE后端(非dentry)：测试中发现的不足和bug-优快云博客

本文档记录了inotify在桌面环境应用中的测试过程，包括handle_rename()引起的内存溢出问题、handle_new()的bug复现及pixbuf组件中的资源管理和效率优化问题。

inotify源码：https://github.com/linuxdeepin/dde/tree/develop/app/desktop

测试代码源码：https://github.com/linuxdeepin/dde/tree/desktop_test/app/desktop/test

1. handle_rename()内存溢出

[ 19%] Testing handle_rename...
** (desktop:4431): WARNING **: Did't know file type /tmp/test_files/360wallpaper38.jpg2
** Message: console message: file:///home/ycl/dde/resources//desktop/js/desktop.js @42: don't support type

[ 19%] Testing handle_rename...

** (desktop:4431): ERROR **: Test handle_rename Failed

跟踪/断点陷阱

void handle_rename(GFile *, GFile *);
Test({
GFile *old_f = g_file_new_for_path(file1);
gchar *filename = g_strconcat(file1, "2", NULL);
GFile *new_f = g_file_new_for_path(filename);
handle_rename(old_f, new_f);

g_free(filename);
g_object_unref(old_f);
g_object_unref(new_f);
}, "handle_rename");

2、void handle_new(GFile* f);

bug同上

3、pixbuf.c中get_data_uri_by_path()中未释pixbuf

现在已释放

char* get_data_uri_by_path(const char* path)
{
    GError *error = NULL;
    GdkPixbuf* pixbuf = gdk_pixbuf_new_from_file(path, &error);
    if (error != NULL) {
        g_warning("%s\n", error->message);
        g_error_free(error);
        return NULL;
    }
    char* c = get_data_uri_by_pixbuf(pixbuf);
    g_object_unref(pixbuf);
    return c;

}

4、pixbuf_to_canvas_data执行效率太低了，很慢

一个百度的logo，test 1分钟才到2%。有待优化，里面就是用两个for循环对图像处理的

char* pixbuf_to_canvas_data(GdkPixbuf* pixbuf)
