gzip

问题 So, I'm trying to write a gzip file, actually from the net, but to simplify I wrote some very basic test. import gzip LINES = [b'I am a test line' for _ in range(100_000)] f = gzip.open('./test.text.gz', 'wb') for line in LINES: f.write(line) f.close() It runs great, and I can see in Jupyter that it has created the test.txt.gz file in the directory listing. So I click on it expecting a whole host of garbage characters indicative of a binary file, like you would see in Notepad. However,

问题 I try to read a Minecraft world with Python from the filesystem and the .mca region/anvil files using the NBT 1.4.1 module (Named Binary Tag Reader/Writer), which is supposed to read the NBT format used in Minecraft. It works fine for files such as level.dat, but throws an error for the region files such as r.0.0.mca Edit: I am referring to the auto generated world files that minecraft stores in the .minecraft/saves/"MyWorld"/ folder. Such as the level.dat (which works), and the mca files

问题 I have a react app with a pretty large build size, it is deployed on an Nginx server with SSL. I learned a bit about GZip and how it can improve the site's performance. But I also came to know that it is not to safe to use GZip with SSL. GZip is enabled for HTML files by default in Nginx. Should I enable it for other files like Javascript and CSS as well to improve performance ? 回答1: When you say it is not to safe to use GZip with SSL i assume that you are talking about Breach Attack. Well

问题 I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response. In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION . I'm not sure regarding the strategies - DEFAULT_STRATEGY , FILTERED and HUFFMAN_ONLY I can make some sense from the Javadoc but I was wondering if someone had used a specific strategy in their apps and if you saw any difference in terms of

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
