【s3cmd】给s3cmd加点debug日志再编一个
时间:2022-07-27
本文章向大家介绍【s3cmd】给s3cmd加点debug日志再编一个，主要内容包括其使用实例、应用技巧、基本知识点总结和需要注意事项，具有一定的参考价值，需要的朋友可以参考一下。
最近有同学反映 s3cmd 上传的数据比原文件小…WTF，居然有这种事？我不信，然后看了下同学的需求，上传一个1G的文件，按照分段上传的默认配置，就是以15M为一段，分段上传，基本公式就是 1024M/15M=68.2。
通过给 s3cmd -d put 加下 debug 日志，查看一下分段上传的过程，发现段数和最后一段的尾巴 Bytes 相加确实就是1024M也就是1G，应该不存在丢数据的问题。
业务场景下，这个文件是通过其他进程写，一般来说他们会先写然后 mv到某个目录下再去上传，那到底是哪个环节有问题呢？
先不管是哪个环节的问题，我先要确认不是 s3cmd 的问题，看了下分段上传的代码，决定分段上传的段数的因素就一个，就是文件的总大小，参考下图，这个 size 是通过 python 的 os.stat() 方法获得的。
直接使用的 debug 信息里没有和这个文件的总大小，debug 日志里只有关于文件分了几段15M地上传以及最后的剩余段，所以这次我 debug 的方法就是把这个 size 打印出来，确认 s3cmd put 里获得文件的大小是没问题的，加入的代码如下，编译完后就会生成 rpm 包和相应的 tar 包，解压出来的目录名是以 commit 名来做后缀的，直接使用就可以了。
然后就是重新编一个 s3cmd 出来了，幸好 s3cmd 有提供 Makefile，一个命令就解决了。下面是 s3cmd 编译的日志。
