Use 'bitmap' node to support more pages
Use 'bitmap node' to support more pages
Feb 14, 2024
It sounds good. But I think we don't need to use the link because the capacity of one 'chunk' is static.So there is a easier way to resolve this,We use all of the first page of each chunk as the meta page.There're also other better solutions such as Windows NTFS and Linux ext file system.Please feel free to discuss here if you have any idea发自我的 iPhone在 2024年2月13日,21:53,Mark Song ***@***.***> 写道:

Currently, the max page cnt of a file is about 65,000. It is limited by ths size of BPFileHeader::bitmap.
Shall we use the bitmap node:
struct BitmapNode {
PageNum prev;
PageNum next;
char bitmap[0];
}
to support Infinite number of pages ?
