没有.

获得压缩流的确切大小的唯一方法是实际去解压缩它(即使您将所有内容都写入/dev/null 并只计算字节数).

The only way to get the exact size of a compressed stream is to actually go and decompress it (even if you write everything to /dev/null and just count the bytes).

值得注意的是，ISIZE定义为

Its worth noting that ISIZE is defined as

ISIZE(输入尺寸)
这包含原始(未压缩)输入的大小
数据模 2^32.

ISIZE (Input SIZE)
This contains the size of the original (uncompressed) input
data modulo 2^32.

在 gzip RFC 中，所以它实际上并不破坏 在 32 位屏障上，您看到的是预期行为.

in the gzip RFC so it isn't actually breaking at the 32-bit barrier, what you're seeing is expected behavior.
