Ungzipping chunks of bytes from from S3 using iter_chunks()

由 冷暖自知 提交于 2020-06-13 05:01:35
问题 I am encountering issues ungzipping chunks of bytes that I am reading from S3 using the iter_chunks() method from boto3 . The strategy of ungzipping the file chunk-by-chunk originates from this issue. The code is as follows: dec = zlib.decompressobj(32 + zlib.MAX_WBITS) for chunk in app.s3_client.get_object(Bucket=bucket, Key=key)["Body"].iter_chunks(2 ** 19): data = dec.decompress(chunk) print(len(chunk), len(data)) # 524288 65505 # 524288 0 # 524288 0 # ... This code initially prints out

Does any mainstream compression algorithm natively support streaming data

由 狂风中的少年 提交于 2020-05-14 11:45:35
问题 Does any mainstream compression algorithm, for example either snappy, zlib or bzip natively support streaming data across the network? For example if I have to send a compressed payload, then will I have to manually prepend the size of the payload before sending the message? Or does any library provide the API to tell whether a message is complete given x bytes? 回答1: zlib, bzip2, lz4, zstd, brotli, lzma2, and many others all support streaming through the use of an end-of-data marker in the

Linux系统运维笔记(四),CentOS 6.4安装Nginx

Linux系统运维笔记(四),CentOS 6.4安装Nginx 1，安装编译工具及库文件 yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel 2，安装 PCRE ，PCRE 作用是让 Nginx 支持 Rewrite 功能。 # yum install -y pcre pcre-devel 　　 3，从官方地址（http://nginx.org/）下载 解压 #tar -zxvf nginx-1.10.3.tar.gz 进入Nginx目录 #cd nginx-1.10.3 Nginx源码编译： #./configure #make #make install 4，先找一下nginx安装到什么位置上了，#whereis nginx ，默认的安装路径为：/usr/local/nginx；跳转到其目录下sbin路径下，便可以启动或停止它了。 ./nginx 启动nginx ./nginx -s stop 停止nginx,此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程。 ./nginx -s quit 停止nginx，此方式停止步骤是待nginx进程处理任务完毕进行停止。 ./nginx -s reload 重启nginx，一般是重新载入配置文件时使用 ./nginx -s
