"How to resolve database deadlock issue caused by parallel goroutines using retry transaction?",
"We are working to build an exchange using Go. Following components are there in the system of now:\n\n\nFrontend \nBackend\nMatching Engine.\n\n\nHere is how the system works:\n\n\nUser creates an order which goes to Backend. \nBackend processes the new order in following manner :\n\n\nIt validates the order request data & then a db transaction is created for updating users account balance in account table & new order is inserted in the order table. \nAfter db interaction is completed; backend produces a new order message in queue. \n\nMatching Engine processes the new order from the queue and pushes the engine response(i.e updated orders & trades) in another queue\nBackend consumes the engine response as below:\n\n\nMultiple goroutines run in parallel to process engine response &store the updates received in engine response. \nFor storing the the updates, a database transaction is created within each goroutine to update the users account balance, orders & store new trades. \n\nProblem occurs during this stage when concurrent (parallel) transactions try to update the same users account at a time, a deadlock is created in DB as multiple transaction try to lock the same record. Also while a users previously placed orders are being matched and processed user can create new order as mentioned in step 2, so transaction created in step 2 also tries to update the same users account in database which is being accessed by backend to store Matching Engine response. This also adds to the chances of deadlock. \nHow to properly manage and prevent the database deadlock generated in above mentioned flow.\nWe have tried a solution to retry transaction by following code but the deadlock issue can still be reproduced\n\n\n // Update accounts, orders, trades with max retry of 5\n for i := 0; i < 5; i++ {\n err = nil\n time.Sleep(10 * time.Second)\n if err = manager.saveEngineResponse(newEngineResponse, accountUpdatesToDoRef, &updatedOrders); err == nil {\n break\n }\n logger.Debug(\"Error saving engine response\", err)\n }\n if err != nil {\n logger.Fatal(err)\n return\n }\n\n\n\n Error : Error 1213: Deadlock found when trying to get lock; try\n restarting transaction\n\n\nI have refered the link : How to avoid mysql 'Deadlock found when trying to get lock; try restarting transaction'\nwhich states that by keeping the operations in a specific order deadlocks can be avoided. And in the above scenario all transaction will first update account, then order & then trades if any. So the order of operations is consistent in different transactions"

"I'm setting up a Lambda as a webhook handler that receive data POSTed from a remote API.\nAs per usual, the external webhook is POSTing the data in the form:\npayload='SOME_JSON' for example payload='{"foo":"bar"}'\nHow can AWS API Gateway be configured to correctly handle application/x-www-form-urlencoded data POSTed from an external webhook, e.g., to correctly map the raw content string into a "form style" parameter name/value pair and pass the value (which is JSON) to the Lambda?\nThe problem is that AWS API Gateway, by default, tries to relay the entire raw string payload=JSONSTRING to the Lambda, but of course the payload= is not JSON, it's the form parameter name, so that generates a 400 error (body not in JSON format).\nTo test, I posted the same data to both the AWS API Gateway, and, so that I can see exactly what is POSTed from the webhook, also to webhook.site for debugging.\nAs shown below the in webhook.site screengrab, the raw data POSTed is in the usual webhook format, "parameter=value" eg payload=JSONSTRING, specifically: payload='{\\"arg1\\":\\"val1\\"}'\nAnd as shown in the webhook.site screengrab, their site completely understood how to map that to a "parameter name" (payload) and the parameter value.\nwebhook.site screengrab:\n\nThe closest I've come is to get the API Gateway & Lambda to stop throwing 400 errors, by using API Gateway's "Body Mapping Template" to at least force the raw content "param=value" into JSON format using this body mapping:\n{"body": "$input.body"}\n\nas described in this helpful blog post: https://blog.summercat.com/using-aws-lambda-and-api-gateway-as-html-form-endpoint.html\n(edit: that blog post was old, Body Mapping Template is not required, API Gateway now supports enabling "Use Lambda Proxy integration" on the Integration Request for the POST method which passed to the Lambda the full input object (headers, payload, etc) as JSON to get rid of the 400 errors. But the "body" key/value in the JSON is still not parse-able JSON, it is prefixed with the payload=")\nBut the problem is the the Lambda event hash still isn't in a usable format it still includes the "payload=...(escaped string)" e.g.\n`{"body"=>"payload=%7B%22arg1%22%3A%22val1%22%7D"\nSo I hope there is some way to configure API Gateway to do what the rest of the world can do, and map the POSTed raw content "payload=JSONSTRING" to a JSON object that is passed to the Lambda, such as {"payload" : "JSONSTRING"} or perhaps just JSONSTRING?"

"MongoDB: adding sort() to query ruins result set for $and query",
"I've stumbled upon some very strange behavior with MongoDB. For my test case, I have an MongoDB collection with 9 documents. All documents have the exact same structure, including the fields expired_at: Date and location: [lng, lat].\n\nI now need to find all documents that are not expired yet and are within a bounding box; I show match documents on map. for this I set up the following queries:\n\nvar qExpiry = {\"expired_at\": { $gt : new Date() } };\nvar qLocation = { \"location\" : { $geoWithin : { $box : [ [ 123.8766, 8.3269 ] , [ 122.8122, 8.24974 ] ] } } };\nvar qFull = { $and: [ qExpiry, qLocation ] };\n\n\nSince the expiry date is long in the past, and when I set the bounding box large enough, the following queries give me all 9 documents as expected:\n\ndb.docs.find(qExpiry);\ndb.docs.find(qLocation);\ndb.docs.find(qFull);\ndb.docs.find(qExpiry).sort({\"created_at\" : -1});\ndb.docs.find(qLocation).sort({\"created_at\" : -1});\n\n\nNow here's the deal: The following query returns 0 documents:\n\ndb.docs.find(qFull).sort({\"created_at\" : -1});\n\n\nJust adding sort to the AND query ruins the result (please note that I want to sort since I also have a limit in order to avoid cluttering the map on larger scales). Sorting by other fields yield the same empty result. What's going on here?\n\n(Actually even stranger: When I zoom into my map, I sometimes get results for qFull, even with sorting. One could argue that qLocation is faulty. But when I only use qLocation, the results are always correct. And qExpiry is always true for all documents anyway)"

"iOS - Using Search API for Google Shopping",
"My ultimate goal is to search for an item (using a query in code) and display some information from a JSON object using the Google Shopping API - Objective-C Client. \n\nI know that the search API for shopping is going to be deprecated very shortly but wanted to at least get something to work just to show that it does work. So short term I would like to get this to work and long term use something similar (such as an Amazon API). \n\nI am targeting iOS 6.0+ and am currently using XCode 4.6. I followed this blog tutorial here for XCode 4.5 and got everything set up as stated here. (Although maybe there is another way to get the pre-built library built - but the blog author said that that did not work)\n\nIf you look at this link they give you an example of how to use the API(under Basics - Objects and Queries) but I have a problem in that I cannot find the GTLServiceGoogleShopping object anywhere. If you use the svn command to checkout the library files you don't get this object nor do you get any example code for this particular service. \n\nI am wondering if anyone has done this in iOS before and/or if anyone would like to recommend an alternative way to do a product search on the web that returns a JSON Object, that is compatible with XCode/iOS and that is as easy to use as the Google Shopping API seems to be. (i.e. use a few objects to make a http request then parse the JSON object as needed). \n\nAny help/information/guidance would be greatly appreciated."

"Reflecting changes made to stored procedure in Entity Framework-generated complex type",
"So I've got a DB in SQL Server that I'm connecting to and using Entity Framework 4.1 to generate my POCO classes, which works generally pretty well. There are also stored procedures that I am using the 'function import' feature to create retrieve the resulting rows of data from calling them. Essentially the process I'm using is to:\n\n\nRight-click on the Model.edmx and choose \"Function Import...\"\nPick the procedure from the dropdown\nEnter my desired Function Import Name\nClick \"Get Column Information\"\nClick \"Create New Complex Type\"\nClick \"OK\"\n\n\nand that will create a POCO class for the result set definition and I can do something like:\n\nvar query = context.GetMyStuff().AsQueryable(); \n\nto retrieve the results. This seems to work just fine.\n\nNow the trouble I'm having is when I try to modify a stored procedure and then get the changes to propagate to my code. For instance, I added an additional column to a table and then updated the stored procedure to return that column data as part of the results. I don't see how to make that update propagate into the function import stuff, i.e., get the generated POCO to have a new property for that added column. \n\nWhat's the drill to make that update to the procedure reflect back in C# side? Am I going to have to make a new class each time? Wasn't obvious to me how to do this.\n\n\n\nAdditional Info:\n\nWhen I've tried to \"Update\" the Complex type, as suggested in the response by Ladislav to this question, I get an error message \"Verify that the FunctionImport name is unique.\"\n\nIf I try what E.J. Brennan suggests below, I get the same error message.\n\nWhat does work, at least for me, is to open the Model.edmx file in Notepad++, find the FunctionImport line and delete it then regenerate it. That's not ideal, but it worked."

"When initializing my aspx page, I declare it (inside OnInit) in the StructureMap container to get it injected into the appropriate presenter:\n\ncontainer.Configure(x => x.For<IMyInterface>().HttpContextScoped().Use(this));\n\n\nHttpContextScope should force removing \"this\" (i.e. the page object) from the container at the end of the current request. To prove it I've added - just after the above line - the following code:\n\nIEnumerable<InstanceRef> refs = container.Model.InstancesOf<IMyInterface>();\nforeach (InstanceRef r in refs)\n{\n Type t = r.ConcreteType;\n}\n\n\nThe question is: \n\nWhy the refs collection increases by 1 in each postback? \n\nIt not only increases but r.ConcreteType doesn't raise any exception - it means that the underlying object really exist. The page is injected into the presenter which is itself declared in the HttpContext scope.\n\nWhat am I doing wrong that HttpContext scope seems to work incorrectly?\n\nThanks in advance\n\n\n\nI've thought it over and the result is as follows. If I configured the container to create a new instance of my class (it (configuration) would be done only once, during Application_Start), the container would create an instance and then - really delete it at the end of the Http request. But I only register the existing instance of this class. The container is not the instance's owner and therefore it may not delete it - but the configuration keeps the reference to it (therefore it can't be deleted at all). At the other side, the configuration item is not removed by anybody, anytime (but added in every Http request).\n\nTherefore all that works as it works. It is, of course, my misunderstanding of \"HttpContextScoped\" (and some other things :-( ).\n\nSo, I'm at the starting point: is there any way to remove such a registration from the configuration?\n\n[Edited]\nIt seems that I can't remove such a registration. The solution is: replace the automatic constructor injection with a manual property injection. I.e.: create the presenter (without its view) and then - set the view manually: thePresenter.View = this;\nThe aforementioned registration is not added and the problem just doeasn't appear."

"Tracking DateAccessed in SQL Server Row?",
"This seems like it should be trivial, but I'm stuck after checking the CREATE TRIGGER docs. No select trigger.\n\nI have a table:\n\nCREATE TABLE [Fileserver].[Files]\n (\n [FileId] [int] IDENTITY(1, 1) NOT NULL ,\n [DateAccessed] [datetime] NULL ,\n [DateCreated] [datetime] NULL ,\n [DateModified] [datetime] NULL\n )\nGO\n\n\nWhen someone reads a row from the table, I want to update the DateAccessed column. DateCreated is handled with a default value of getdate(), and DateModified with a trigger. I cannot think of a way to handle DateAccessed WITHOUT limiting table access to a stored procedure. Our team is making heavy use of Linq2Sql, so I prefer to allow SQL selects on the table.\n\nThanks!"

"GLPaint with GLKit: flickering when drawing",
"I'm having a problem with GLKit in a project that is similar to GLPaint. \n\nFirst of all, I'm not using GLKViewController, but only a GLKView which is added to my class.\n\nMy problem is that when I draw in my GLKView, the content flickers. It looks as if I was drawing in a certain frame buffer in the first call to GLKViewDelegate's drawRect and next call it was a different frame buffer, then next call it came back to the first one, etc.\nI have tested this possibility and it does not seem to be the case, both render buffer and frame buffer are the same in all the drawing.\n\nHere is how my drawing works (similar to GLPaint sample code):\n\nOn touch events, I call renderStroke to generate points that are used in the drawing to apply the textures and present a line. I am using custom shaders, so I place the buffer containing these points in a pre-specified spot so the shader has access to it:\n\n// Give the vertex positions to the vertex shader\nglVertexAttribPointer(ATTRIB_POSITION, 2, GL_FLOAT, 0, 0, vertexBuffer);\nglEnableVertexAttribArray(ATTRIB_POSITION);\n\n\nThen, in the draw method, I call glDrawArrays: \n\n- (void)glkView:(GLKView *)view drawInRect:(CGRect)rect {\n glDrawArrays(GL_POINTS, 0, self.verticesCount);\n}\n\n\nHere is how I initialize the GLKView:\n\nself.glView = [[GLKView alloc] initWithFrame:self.frame];\nself.glView.context = _context;\nself.glView.delegate = self;\nself.glView.drawableColorFormat = GLKViewDrawableColorFormatRGBA8888;\nself.glView.drawableStencilFormat = GLKViewDrawableStencilFormat8;\nself.glView.enableSetNeedsDisplay = NO;\nself.glView.userInteractionEnabled = NO;\n[self addSubview:self.glView];\n\n\nThe texture, modelViewProjection matrix seem to work properly since I can see the right texture applied to every point. \n\nI've been searching ways to debug this, but everything I saw seemed normal. Is there something I'm missing?\n\nThanks!\n\nEDIT: \n\nI am wondering, when drawRect is called, is the color_render_buffer and stencil_buffer meant to be cleared before further drawing is done? My goal here is to keep the drawing I have done previously and draw other content on top of it. Without GLKit, this is normally done using kEAGLDrawablePropertyRetainedBacking. I have set it on the glView layer using: \n\nCAEAGLLayer * const eaglLayer = (CAEAGLLayer*) self.glView.layer;\neaglLayer.opaque = NO;\neaglLayer.drawableProperties = @{kEAGLDrawablePropertyRetainedBacking : @(YES)};\n\n\nThis does not seem to work however."
