![]() In pseudocode, this is what I did var lineCounter = 0 Īgain, different situation might require different way to find the last time the connection.query() will be called. While I can verify that it is being called when I re-invoke it from the home screen (and when onCreate()/onCreateView() is not called), it seems to retain the old value for 'feature' (and, I assume, the entire old Intent). If original process has made the last call, then call connection.end() in the last callback of the last asynchronous chained function.įor the program I was working on, I counted the lines that was read from the file and I matched the count to another counter counting how many records I have inserted. However, the general idea is to keep track of the original process (in this case reading my file) and check against the last process (in this case my sql insert). With multiple chained asynchronous callbacks, how could I know when will that last connection.query() be called?ĭifferent problems may require different exact implementation. node.js Cannot enqueue Handshake after invoking quitEllen1995- node. 19:45 Pawel Laszczak 0 siblings, 0 replies 81+ messages in thread From: Pawel Laszczak 19:45 UTC ( / raw) To: devicetree Cc: gregkh, felipe.balbi, tland, linux-usb, hdegoede, heikki.krogerus, andy. Cannot enqueue Handshake after invoking quit The reason for the error is that the connection object of the database is designed so that it cannot be. Eureka! I need to call it after the last connection.query() ran. Fixing Node Mysql 'Error: Cannot enqueue Handshake after invoking quit.': TL DR createConnection. PATCH v4 0/6 Introduced new Cadence USBSS DRD Driver. “cannot enqueue query after invoking quit”Īfter another few hours of searching the web, node-inspector debugging, and tons of debugger command and console.log(), the dark cloud was lifted away. After a few hours, as I thought I’m close to being done, I get this error: So here I am with node.js, chrome dev tool, asynchronous functions everywhere, trying to process information from a file and insert them into mysql. What better way to go back at it than working with a framework that I have never code in before? Using tools that I’ve never used before! Of course! (Sarcastic laugh, then cry…) The problem with this fix is that, often, even though all the MySQL calls finish, the res.redirect () fails. This leads me to believe that the way I'm creating models in Express is fundamentally broken.After years focusing almost exclusively on management and a bit of high level enterprise system architecture, I’m starting to code again. Fixing Node Mysql 'Error: Cannot enqueue Handshake after invoking quit.': TL DR createConnection. I often get the following app crash error: 'Cannot enqueue quit after invoking quit.' My kluge solution, which doesn't work very well, is to put a setTimeout function at the end of the route to wait to give the MySQL processes enough time to finish before the connection.end () (or, in this case, pool.end ()). This code un-modified from the models/user.js in my API. Tenho um objeto que ele faz uma consulta no banco MySQL localizando um CNPJ de um cliente, caso ele não encontre ele cadastra esse cliente, se encontrar ele retorna o cliente. Here is script which calls the model //main.jsĬonsole.log(ctime.getTime(), 'user data: ', er_id)Ĭonsole.log(ctime.getTime(), 'user data: ', er_id) Mysql_connection = mysql.createConnection(configs) Ĭonsole.log(`getUserByEmail: connection id: $) These are PRIVATE variables, they can only be accessed within this class a/hotspot/src/cpu/sparc/vm/assemblersparc.cpp Thu Jul 21 08:38:25 2011 -0700 +++ b/hotspot/src/cpu/sparc/vm/assemblersparc.cpp Thu Jul 21 11:25:07 2011 -0700. This means that you cannot enqueue the Handshake. You’ll need to use a Promise or callback instead of a Handshake to ensure that you’re still able to make calls to the bank. That’s because the system won’t be able to create a pool. * This constructor function is responsible for running queries against Similarly, if you’re using a lambda function, you can’t enqueue a Handshake after invoking quit. The reason is, if I take the code from my model and create a CLI script, no errors are returned, mysql doesn't issue any warnings // models/user.js GIT pull irq/core for v5. I don't think the error is in the mysql module. You'll see that the correct answer is returned, but node blows errors. The project is small, just put your database credentials in the the configs/mysql.js file, then run the file node multiple_sends.js You can check it out, I've created an SQL seeder with 2 users so you can just copy paste the query into your database (the seeder even creates a new database) The odd thing is, I get a valid and correct results returned to API requests, but, clearly something is wrong. Everything works fine if I make one request at a time, but, if 2 or more requests hit the server within a second of each other, I get the following error Error: Cannot enqueue Quit after invoking quit
