            Transfer two transaction in one function
            Asked 2022-Apr-14 at 16:06

            I want to pay two transactions within one function. The msg.sender should pay a fee to the contract first. The rest which is still in msg.value should be transferred to the seller. I always get an error. To clarify i tested both transactions by their own and it worked and i have implemented a receive() function that the contract can receive the funds. Here is the code:

            ...

            ANSWER

            Answered 2022-Apr-14 at 14:52

            Your snippet is trying to send more funds than the contract has - which causes the whole transaction to revert.

            The contract has 0 MANTIS before the transaction invoking sendMoney().

            The transaction sent along 0.1 MANTIS ( == 100000000000000000 wei), which is reflected in the msg.value global variable.

            The first transfer() sends 10 wei, so the left available balance is now 99999999999999990 wei (10 less than 0.1 MANTIS). But the second transfer() is trying to send 100000000000000000 (the msg.value), which is 10 wei more than the contract has available at the moment.

            Solution: Lower the second transfer by the already sent amount.

            When sending ether to another contract it sends it to the contract?
            Asked 2022-Apr-14 at 08:54

            I try to send ether from one address to another. But in the transaction the receiver seems to be the contract address. My goal is to send from address 1 to address 2:

            address1:0xDb7c83d499787E6b7660C961F8a9999E3C395AdE address2:0x9199D9323b25BA171De6b9189201Bb322Ba12274

            But the receiver in the transaction appears to be the contract: https://blockscout.mantis.hexapod.network/tx/0x9bc22ad45dbf60881151c3b94b3d3daa98bc84b1906f1ed131ee2ca9a89484eb/internal-transactions

            Function:

            function sendMoney() public payable {

            address payable seller = payable(0x9199D9323b25BA171De6b9189201Bb322Ba12274);

            ANSWER

            Answered 2022-Apr-14 at 08:54

            When you're invoking the sendMoney() function, you're sending a transaction to the contract that implements this function.

            The seller.transfer(msg.value); is an internal transaction - a part of the main transaction.

            Unable to update submodule from Github within WSL

            I'm having trouble updating the submodules I use for my vim configuration despite everything else working from a GitHub perspective.

            I have already followed github's "generating SSH keys" as well as "adding SSH keys to github" article multiple times and have re-added my SSH key multiple times. I have tried the ed protocol, as well as the RSA and neither seems to work.

            Strangely enough, all other tests for whether or not I'm connected work. I'm able to git clone a raw repository without a problem, even private repositories using ssh links.

            I can also use the ssh -T git@github.com command fine and it says i'm authenticated with my proper user account and everything.

            First, try the same test with a private ssh key without passphrase, again, for testing only.
            That way, you don't have to deal with the ssh-agent while you are checking for the root cause of that "Permission denied" issue.

            Check again that ssh -Tv -i /my/private/key git@github.com does work (display a Welcome message)

            Second, set the GIT_SHS_COMMAND environment variable to display debug information:

            Implementation of automated workflow testing
            Asked 2021-Feb-05 at 23:03

            I have doubts on how to implement test automation in the company where I am currently. I was wondering what workflow do you suggest?

            The project I will be working on uses, on its back-end, the Java language. At first, I want to propose the use of Selenium Webdriver with Java, but some gaps remain:

            1. How would I integrate with problem tracking tools? (Mantis or Jira)
            2. A team member suggested using Python with Selenium Webdriver, is it interesting? (I am afraid)
            3. When developers are committed to the QA environment, how would I do automated testing automatically?

            Thank you in advance for your help!

            With the evolution of AUT (Application under Test) the project is sure to scale up vertically and horizontally. Hence to maintain a healthy Test Coverage you have to set up an Automation Test Suite to validate the Regression Tests.

            Mantis and Jira both can be integrated using either of the Selenium clients Java and Python on demand.

            While for Java clients testng is a popular framework, for Python clients you can use the unittest framework.

            Nginx reverse proxy - Internal servers separated by trailing slash
            Asked 2020-Sep-20 at 12:58

            I'm a newbie at Nginx, and have been searching a lot for the right answer to my question, but couldn't find it; not because it is not there, but my newbie condition limits me to adapt a generic solution to my issue.

            The situation is this: I have a Mantis Bug Tracker in my private LAN (http://10.111.111.12). On the other hand, i have an OwnCloud website also on my LAN (IP 10.111.111.5), with URL http://10.111.111.5/owncloud/.

            What i want to do is to deploy a Nginx Reverse Proxy that handles all requests from Internet at publicdomain.com, and use trailing slash for each internal webserver. The desired result would be:

            http://www.publicdomain.com/bugtracker -> redirects to http://10.111.111.12/index.php http://www.publicdomain.com/cloud -> redirects to http://10.111.111.5/owncloud/ (note that "cloud" is preferred over "owncloud")

            On the future, it is necessary to continue using trailing slash for other web servers to be deployed.

            Questions are: is this scenario possible? if so, is it enough with configuring nginx or I have to reconfigure internal web servers as well?

            I really appreciate your help, by indicating me a possible solution or pointing me to the right direction on previous posts.

            Thanks a lot in advance.
