couozu / leveldbwin Goto Github PK

在发现这里之前我也自己尝试port leveldb(rev 49)到windows, 
代码部分是借鉴网上的(也包含你的), 测试都能通过, 
希望对你有点用处.

我是来自csdn的朋友，请教能否用vc2008编译leveldb
并请教能否用leveldb存储blob值，如果数据流在1T～2T之间，每��
�blob大约30K，性能将会如何？

Would like to use this project but several source files are missing license 
headers.  Perhaps it should use the standard leveldb source files header which 
looks like:


    // Copyright (c) 2011 The LevelDB Authors. All rights reserved.
    // Use of this source code is governed by a BSD-style license that can be

如果想要让程序在64位机上运行，不知要添加哪些改动？

All tests passed on debug build, but on release build, DBTest.Randomized always 
fails.

My build env: VS 2010 + SP1, Windows 7
Revision: r16(latest by now)

Error message:

Any comments?

I've attached a set of patches I made to provide x64 support. I'd be happy to 
explain any/all of it if there was any interest in merging.

我不知道leveldb如何更改才可以支持windows
可以给出wiki么？让我自己动手也行。现在 
没那么多时间研究。
如果有人 可以 改下，将leveldb最新的1.5版本 
更新，那就好了！

What steps will reproduce the problem?
1. Visually inspect the source code of slice.h.
2. Notice lossy integer conversion error.

What is the expected output?
Integer assignments to larger or same bit length.

What do you see instead?
size_t assigned to int ()

What version of the product are you using? On what operating system?
Current online source.

Please provide any additional information below.

Slice size_t member is declared as size_t:
size_t size_;

Later min_len is assigned the value of the size_ member.
const int min_len = (size_ < b.size_) ? size_ : b.size_;
