"Trying to make PLY work for the first time",
"I'm new to Python and I'm having some problems trying to make PLY works. For now, all I want is to successfully run the example from the PLY homepage.\n\nAt first I tried to just download PLY-3.8, put the ply folder in the same directory I saved the example (calc.py) and ran it. The calc.py file is at the C:\\Users\\...\\Python directory and the ply folder is the C:\\Users\\...\\Python\\ply, just to make it clearer. But I got an ImportError: No module named 'ply'.\n\nThen I searched for a while, tried to update something called distutils and install the modules through the Windows PowerShell and so on and so forth, but none of that worked and I just reset the whole thing (reinstalling Python and all of that). But then I finally got it to work by simply inserting into the sys.path the directory path where the script I was running (edit: in interactive mode) was, by doing this:\n\nimport sys\nsys.path.insert(0,'C:\\\\Users\\\\ ... \\\\Python')\n\n\nThis fixed the ImportError but, and this is where I am now, there are a bunch of other errors:\n\nTraceback (most recent call last):\n File \"C:\\Users\\...\\Python\\calc.py\", line 48, in <module>\n lexer = lex.lex()\n File \"C:\\Users\\...\\Python\\ply\\lex.py\", line 906, in lex\n if linfo.validate_all():\n File \"C:\\Users\\...\\Python\\ply\\lex.py\", line 580, in validate_all\n self.validate_rules()\n File \"C:\\Users\\...\\Python\\ply\\lex.py\", line 822, in validate_rules\n self.validate_module(module)\n File \"C:\\Users\\...\\Python\\ply\\lex.py\", line 833, in validate_module\n lines, linen = inspect.getsourcelines(module)\n File \"c:\\users\\...\\python\\python35\\lib\\inspect.py\", line 930, in getsourcelines\n lines, lnum = findsource(object)\n File \"c:\\users\\...\\python\\python35\\lib\\inspect.py\", line 743, in findsource\n file = getsourcefile(object)\n File \"c:\\users\\...\\python\\python35\\lib\\inspect.py\", line 659, in getsourcefile\n filename = getfile(object)\n File \"c:\\users\\...\\python\\python35\\lib\\inspect.py\", line 606, in getfile\n raise TypeError('{!r} is a built-in module'.format(object))\nTypeError: <module '__main__'> is a built-in module\n\n\nNow I have absolutely no idea what to do. I tried to search for a solution but had no luck. I appreciate if anyone can help me out.\n\nI'm on Windows 10, using Python 3.5.0 and iep as my IDE (www.iep-project.org) if these informations are of any importance.\n\nIn short: I just want to successfully run the example from the PLY homepage and then I think I can figure out the rest.\n\nEDIT: I found out that if I do:\n\nimport inspect\ninspect.getfile(__main__)\n\n\nI get the exact same (last) error from before:\n\nTraceback (most recent call last):\n File \"<console>\", line 1, in <module>\n File \"c:\\users\\...\\python\\python35\\lib\\inspect.py\", line 606, in getfile\n raise TypeError('{!r} is a built-in module'.format(object))\nTypeError: <module '__main__'> is a built-in module\n\n\nI think this is the culprit, but I still don't know how to fix it.\n\nEDIT 2: I got it to work and answered the question explaining how, but if someone have a more complete answer, I would love to hear it."

However, when I click outside the EditText view, the onItemClick() method is not being called.\n\nI considered the fact that the EditText within the ListView item was causing the ListView events to be caught and not propagated. I took out the EditText from the above layout file and the onItemClick() method was called, as expected.\n\nThis would lead me to believe that the sibling TextViews of the EditText view could receive click events. This was correct. That worked. It also led me to believe that the ancestor LinearLayouts of the EditText would NOT receive click events if I clicked outside the EditText view. This is not the case. Both the parent LinearLayout holding the EditText AND the grandparent LinearLayout that holds the entire ListView item both received click events whenever I clicked outside the EditText view. Clicking inside the EditText view did not, however, propagate to its ancestors. That is what I had hoped.\n\nSo if the ancestor widgets are able to receive click events outside the EditText, why then, is the parent ListView not receiving the event to trigger the onItemClick() method? Why does the EditText prevent events from propagating back to the ListView?\n\nThank you in advance for your help."

I am running into what appears to be a common issue and that is that the entire stream does not make it to the client.\n\nHere is my server code:\n\n//Returns Customer Info\nfunction TServerMethods.GetBPInfo(CardCode : String): TStringStream;\nbegin\n Result := TStringStream.Create;\n try\n qBPInfo.Close;\n if CardCode.Trim = '' then\n qBPInfo.ParamByName('ParmCardCode').AsString := '%%'\n else\n qBPInfo.ParamByName('ParmCardCode').AsString := '%' + CardCode + '%';\n qBPInfo.Open;\n FDSchemaAdapterBPInfo.SaveToStream(Result, TFDStorageFormat.sfBinary);\n Result.Position := 0;\n // Result.SaveToFile('output.adb');\n except\n raise;\n end;\nend;\n\n\nHere is my client code:\n\nprocedure TdmDataSnap.GetBPInfo(CardCode : String);\nvar\n LStringStream : TStringStream;\nbegin\n dmDataSnap.FDStoredProcBPInfo.ParamByName('CardCode').AsString := CardCode;\n FDStoredProcBPInfo.ExecProc;\n LStringStream := TStringStream.Create(FDStoredProcBPInfo.ParamByName('ReturnValue').asBlob);\n //LStringStream.Clear;\n //LStringStream.LoadFromFile('Output.adb');\n try\n if LStringStream <> nil then\n begin\n LStringStream.Position := 0;\n try\n DataModuleFDClient.FDSchemaAdapterBP.LoadFromStream(LStringStream, TFDStorageFormat.sfBinary);\n except\n on E : Exception do\n showmessage(e.Message);\n end;\n end;\n finally\n LStringStream.Free;\n end;\nend;\n\n\nYou will see the stream save and load code; that is how I determined that the server was getting the entire result set into the stream, and that the client could handle the entire result set and display it properly.\n\nSo smaller streams transfer just fine, but this big one, when examined in the ide debugger, does not start with the 65,66,68,83 characters and the load fails with the error, '[FireDAC][Stan]-710.

I'm trying to stay with this coding scheme. \n\nHow do I adapt this code to correctly receive large streams?\n\nUpdate 1:\n\nOk, I tried strings and Base64 encoding.

I'm working on improving query times to eagerly load an entity with several nested child objects, and have reduced the number of queries by using .Include(\"Object.Child\") to bring in navigation properties. At first, I thought I was getting a good result, seeing the \"Total query execution time\" in the SQL tab of Glimpse reduce significantly. Yet the \"Total connection open time\" stays high, and is very long for the resulting combined mega-query. See screenshot below.\n\nI'm wondering if anyone can help me understand what is going on with the differences in the two durations? Glimpse says my command takes <100 ms, but that the SQL connection takes >5 seconds. The query in this case is really messy with lots of joins etc, however it's not clear where the time goes if indeed the query itself finishes in 100 ms. \n\nNote: I've seen the answer about why two durations here, but it doesn't explain the nature of each."

I've been following every step in this tutorial and I've double checked everything -- it is exactly the same as in this tutorial. I see other people who have similar problems are always because of incorrect debug hash code. But I've checked like a million times that I got the correct debug hash code. Some people say that if you wanna release an app, you need a release code. However, I'm not releasing my app -- I'm just testing it on an android device, so I guess I dont really need a release code to do that?\n\nAlso, I've checked that I've included my facebook application id for this app in the Android Manifest. So basically, everything I did was strictly following the tutorials on Facebook Developers.\n\nI've seen some people suggesting to use the \"keytool\" in JDK 6 in stead of JDK 7. And I've checked that I actually did generate my debug hash code with the \"keytool\" in JDK 6.\n\nSo I've tried everything, but the problem still exists!\n\nIn that Android Tutorial, it suggests putting this in your code so that you can monitor your LogCat to see if your current state is logged in or logged out:\n\nprivate void onSessionStateChange(Session session, SessionState state, Exception exception) {\n if (state.isOpened()) {\n Log.i(TAG, \"Logged in...\");\n } else if (state.isClosed()) {\n Log.i(TAG, \"Logged out...\");\n }\n}\n\n\nIn my case, no matter how many times I clicked Facebook Login Button, I always got \"Logged out...\" in my LogCat.\n\nAlso, the funny thing is, I can't even log in facebook using those sample apps coming with Facebook Android SDK 3.0.1 (eg. SessonLoginSample)!!!!! When I click the login button in those sample apps, nothing happens -- which means I'm not successfully logged in.\n\nI really hope you guys out there can help me with this problem. It's weird I don't see other people with the exact same problem (as I said, those with similar problems are always because of incorrect debug code, but I've checked mine, it is 100% correct).

"Does ignoring a base type in Entity Framework Code First also ignore subclasses?",
"I'm attempting to simulate a scenario in which I am inheriting from concrete base classes in a 3rd party library, then mapping my own classes using Entity Framework Code First. I would really prefer for my classes to have the same simple name as the base classes. I obviously can't change the class names of the base classes, nor can I change the base class to abstract. As expected, I get the following error:\n\n\n The type 'EfInheritanceTest.Models.Order' and the type\n 'EfInheritanceTest.Models.Base.Order' both have the same simple name\n of 'Order' and so cannot be used in the same model. All types in a\n given model must have unique simple names. Use 'NotMappedAttribute' or\n call Ignore in the Code First fluent API to explicitly exclude a\n property or type from the model.\n\n\nAs I understand it, in EF6 this is possible so long as only one of the classes is actually mapped. However, if I attempt to ignore the base class using the fluent API, I get the following error instead:\n\n\n The type 'EfInheritanceTest.Models.Order' was not mapped. Check that\n the type has not been explicitly excluded by using the Ignore method\n or NotMappedAttribute data annotation. Verify that the type was\n defined as a class, is not primitive or generic, and does not inherit\n from EntityObject.\n\n\n... which seems to indicate that by ignoring the base class, I ignore any subclasses as well. Full code below. Any way to work around this and \"unignore\" the subclass? Or is this a limitation of EF type mapping?\n\nnamespace EfInheritanceTest.Models.Base\n{\n public class Order\n {\n public virtual int Id { get; set; }\n public virtual string Name { get; set; }\n public virtual decimal Amount { get; set; }\n }\n}\n\nnamespace EfInheritanceTest.Models\n{\n public class Order : Base.Order\n {\n public virtual DateTime OrderDate { get; set; }\n }\n}\n\nnamespace EfInheritanceTest.Data\n{\n public class OrdersDbContext : DbContext\n {\n public OrdersDbContext() : base (\"OrdersDbContext\") { }\n\n public IDbSet<EfInheritanceTest.Models.Order> Orders { get; set; }\n\n protected override void OnModelCreating(DbModelBuilder modelBuilder)\n {\n base.OnModelCreating(modelBuilder);\n modelBuilder.Types<Models.Base.Order>().Configure(c => c.Ignore());\n modelBuilder.Types<Models.Order>().Configure(c => c.ToTable(\"order\"));\n modelBuilder.Entity<Models.Order>().Map(c =>\n {\n c.MapInheritedProperties();\n c.ToTable(\"order\");\n });\n\n }\n }\n}"

I have to do this in the WAS server, so what do I need to do? I mean, I have read that it defines some security roles in the application.xml that binds with the WAS server, and that they need some ids that look through the ibm-application-bnd.xmi\n\nIt also seems that I need some kind of ibm-web-bnd.xmi to just reconfigure my web.xml with the same users (which gets me terribly confused).\n\nDo I need to create these files (I don't have a RAS, just an Eclipse Galileo (yeah, I also sometime think I am playing in hard mode), so I have no way to do this automatically) or can I just configure the application.xml and the web.xml correctly without these files? I have managed myself to more or less create these files and finally create an EAR that the WAS has deployed (correctly, it says). \n\nThis sounds a hell of lot complex for just a user validation, so I don't now if I am right or wrong. \nProbably wrong, since WAS keeps saying \"com.ibm.websphere.security.PasswordCheckFailedException: No user wasadmin found\".\n\nIs there any insightful documentation of how to do this?\n\nThanks!"

"Unexpected behaviour with using STM32 QSPI over HAL",
"I am using the QSPI (or dual-SPI) interface of the STM32L452 to create instructions for an LED driver using the HAL. I have managed to get it to work but I have to set quite absurd configuration options for the command to make it work.\nHere's my initialization code:\n hqspi.Instance = QUADSPI;\n hqspi.Init.ClockPrescaler = 31;\n hqspi.Init.FifoThreshold = 1;\n hqspi.Init.SampleShifting = QSPI_SAMPLE_SHIFTING_NONE;\n hqspi.Init.FlashSize = 31;\n hqspi.Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_1_CYCLE;\n hqspi.Init.ClockMode = QSPI_CLOCK_MODE_0;\n hqspi.Init.FlashID = QSPI_FLASH_ID_1;\n hqspi.Init.DualFlash = QSPI_DUALFLASH_DISABLE;\n HAL_QSPI_Init(&hqspi);\n\nHere's the code I'm using to set up the command\n qspiCommand.InstructionMode = QSPI_INSTRUCTION_NONE;\n qspiCommand.AddressMode = QSPI_ADDRESS_NONE;\n qspiCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE;\n qspiCommand.DataMode = QSPI_DATA_2_LINES;\n qspiCommand.DummyCycles = 0;\n qspiCommand.NbData = 81;\n qspiCommand.DdrMode = QSPI_DDR_MODE_DISABLE;\n qspiCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY; // I have to set this\n qspiCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD; // I have to set this\n\nThen I send it off using HAL_QSPI_Command and HAL_QSPI_Transmit.\nHere's the output that I expect and that I can achieve using the code above:\n\nMind that this is a one-off transfer, and is only output when I call the two functions above.\nThe weird thing is that I have to set\nqspiCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY;\n\n(which should not have an effect when DdrMode is disabled)\nand\nqspiCommand.SIOOMode = QSPI_SIOO_INST_EVERY_CMD;\n\n(which should not have an effect when InstructionMode is none).\nIf I do not set both of them, weird things happen. This is the output if I remove the DdrHoldHalfCycle parameter:\n\nMind that this is a continuous signal, which starts and won't stop after I called the transmit function.\nWhat am I missing here? I really shouldn't need those parameters to make it work."
