warc | Web archiver to bundle web page

I currently parsing WARC files from CommonCrawl corpus and I would like to know upfront, without iterating through all WARC records, how many records are there.

Does WARC 1.1 standard defines such information?

Half of the buffer used with ReadFile is corrupt. Regardless of the size of the buffer, half of it has the same corrupted character. I have look for anything that could be causing the read to stop early, etc. If I increase the size of the buffer, I see more of the file so it is not failing on a particular part of the file.

Visual Studio 2019. Windows 10.

Hi I'm working on a project for fun with the common crawl data I have a subset of the most current crawls warc file paths from here

so basically I have a url like https://commoncrawl.s3.amazonaws.com/crawl-data/CC-MAIN-2020-45/segments/1603107863364.0/warc/CC-MAIN-20201019145901-20201019175901-00000.warc.gz (the first url in the warc paths) and I am streaming in the request like so:

Processing Common Crawl warc files. These are 5gb uncompressed. Inside there is text, xml and warc headers.

This is the code I am particulary having trouble with:

Assuming I have:

• the link of the CC*.warc file (and the file itself, if it helps);
• offset; and
• length

How can I get the HTML content of that page?

Thanks for your time and attention.

I'm very new to Python and I'm having trouble working on an assignment which basically is like this:

#Read line by line a WARC file to identify string1.

#When string1 found, add part of the string as a key to a dictionary.

#Then continue reading file to identify string2, and add part of string2 as a value to the previous key.

#Keep going through file and doing the same to build the dictionary.

I can't import anything so it's causing me a bit of trouble, especially adding the key, then leaving the value empty and continue going through the file to find string2 to be used as value.

I've started thinking something like saving the key to an intermediate variable, then going on to identify the value, add to an intermediate variable and finally build the dictionary.

I am downloading common crawl files from AWS. Apparently, they are large concatenated .gz files, which is supported by the gzip standard. I am using zlib to deflate but I only get the decompressed contents of the file up to the first concatenation. I have tried adding inflateReset() but then I get error -5, which indicates a buffer or file problem. I suspect I am close.

here's the code without inflateReset. It works fine on non-concatenated files.

I have successfully crawled a website using Nutch and now I want to create a warc from the results. However, running both the warc and commoncrawldump commands fail. Also, running bin/nutch dump -segement .... works successfully on the same segment folder.

I am using nutch v-1.17 and running:

I'm having difficulties in making a Tokio client that receives packets from a server and stores them in a queue for the main thread to process, while being able to send packets to the server from another queue at the same time.

I'm trying to make a very simple online game demonstration, having a game client that Sends data (it's own modified states, like player movement) and receives data (Game states modified by other players & server, like an NPC/other players that also moved).

The idea is to have a network thread that accesses two Arcs holding Mutexes to Vec that store serialized data. One Arc is for IncomingPackets, and the other for OutgoingPackets. IncomingPackets would be filled by packets sent from the server to the client that would be later read by the main thread, and OutgoingPackets would be filled by the main thread with packets that should be sent to the server.

I can't seem to receive or send packets in another thread.

The client would only connect to the server, and the server would allow many clients (which would be served individually).

The explanations around stream's usage and implementation are not newbie-friendly, but I think I should be using them somehow.

I wrote some code, but it does not work and is probably wrong.

(My original code does not compile, so treat this as pseudocode, sorry)
