Send file using Tornado in Python-3.6

Asked 2021-Jun-14 at 00:23

I am trying to send back a file using REST GET with Tornado but the checksum of the returned file is different every time. What could the reason be behind this? Are the chunks returned in incorrect order?

I am using curl to download the file.

Thanks for any advice! :-)

ANSWER

Answered 2021-Jun-07 at 14:54

The problem in the code was that I wrote some extra data to the REST client which ended up in the downloaded file. I also found that curl adds some extra headers in the downloaded file which wget does not do. Tried with -s and --silent but that did not help. Below data was added to the start of the file.

Calculate CRC for File(content)

TLDR: Create a CRC from every file(contentbased) in Directory.
Currently i used from Cpp20 the Filesystem Libary and tried to create a checksum for a file with "hash_value(p)". The thing is, the value does not change. Can you provide me some advice ho to accomplish a checksum, that changes when file content is changed. I would like to stay within the range of CPP libarys or what debian 10 can provide.
Now i tried this:

The thing is, the value does not change.

It's not supposed to. The filesystem::hash_value is a hash of the path to the file, not the contents of the file. If you want to compute a CRC of the contents of a file, you're going to have to read those contents and apply a CRC algorithm to them.

Check if sum possible in array

Asked 2021-Jun-11 at 06:47

Given an array of N nonnegative integers and a target sum, check if it is possible to obtain target by choosing some elements of the array and adding them up. (An element can be chosen multiple times).

I tried to come up with a brute force recursive solution. My idea is that for each element, we have 3 choices

Include the element and stay in the same index
Include the element and move to the next index
Exclude the element and move to the next index

Here's my C++ code

If the array has a non-positive number (such as zero) in it, your solution will never stop iterating.

Unable to install JDK 16 on RPi

Asked 2021-Jun-10 at 15:46

I want to install the JDK 16 on a RPi 3B and I downloaded the Linux ARM 64 Compressed Archive from the Oracle site. Every time I run the command to check the version of java I get the same error: bash: ./java: cannot execute binary file: Exec format error

I already tried to untar it again and download the archive from zero, but I get the same error every time. Considering the RPi 3B not able to support the JDK16 for some reason, I downloaded and installed the Kit on a RPi 4 too, but the result is always the same. I used the checksum to make sure the downloaded archive was intact and it was.

Am I downloading the wrong package or have I missed anything important?

It seems you are running a 32 bit ARM Linux (armv7l), you therefore cannot execute a 64 bit aarch64 JDK. You need to install the 32 bit version, the same way you installed the 64 bit JDK, or to install a 64 bit Linux distribution on your system.

QUESTION

Why we use 1's complement instead of 2's complement when calculating checksums

Asked 2021-Jun-09 at 16:08

When calculating UDP checksums I know that we complement the result and use it to check for errors. But I don't understand why we use 1's complement instead of 2's complement (as shown here). If there are no errors 1's complement results -1 (0xFFFF) and 2's complement results 0 (0x0000).

To check for correct transmission, receiver's CPU must first negate the result then look at the zero flag of ALU. Which costs 1 additional cycle for negation. If 2's complement was used the error checking would be done simply by looking at the zero flag.

...

ANSWER

Answered 2021-Jun-09 at 16:08

That is because using 2's complement may give you a wrong result if the sender and receiver machines have different endianness.

If we use the example:

0000 1111 1110 0000 1111 0000 0001 0000

the checksum with 2's complement calculated on a little-endian machine would be:

0000 0000 0001 0000

if we added our original data to this checksum on a big-endian machine we would get:

0000 0000 1111 1111

which would suggest that our checksum was wrong even though it was not. However, 1's compliments results are independent of the endianness of the machine so if we were to do the same thing with a 1's complement number our checksum would be:

0000 0000 0000 1111

which when added together with the data would get us:

1111 1111 1111 1111

which allows the short UDP checksum to work without requiring both the sender and receiver machines to have the same endianness.

It turns out that the default user in mcr.microsoft.com/windows/nanoserver:1809 is ContainerUser, a non-administrator account. I'm not sure the exact permissions Docker's COPY command uses on Windows containers. On Linux it creates files owned by root though, so something similar in Windows. Switching to the ContainerAdministrator user (USER ContainerAdministrator) for the npm install process fixed my permissions problems.

Maven Artifactory plugin 3.2.3 is recently released. This version includes a fix for this issue.

The root cause is a new field returned from Artifactory in the response of the upload REST API. The fix is to ignore new unknown fields instead of throwing the UnrecognizedPropertyException.
