  • What database table structure should I use for versions, codebases, deployables?

    - by Zac Thompson
    I'm having doubts about my table structure, and I wonder if there is a better approach. I've got a little database for version control repositories (e.g. SVN), the packages (e.g. Linux RPMs) built therefrom, and the versions (e.g. 1.2.3-4) thereof. A given repository might produce no packages, or several, but if there are more than one for a given repository then a particular version for that repository will indicate a single "tag" of the codebase. A particular version "string" might be used to tag a version of the source code in more than one repository, but there may be no relationship between "1.0" for two different repos. So if packages P and Q both come from repo R, then P 1.0 and Q 1.0 are both built from the 1.0 tag of repo R. But if package X comes from repo Y, then X 1.0 has no relationship to P 1.0. In my (simplified) model, I have the following tables (the x_id columns are auto-incrementing surrogate keys; you can pretend I'm using a different primary key if you wish, it's not really important): repository - repository_id - repository_name (unique) ... version - version_id - version_string (unique for a particular repository) - repository_id ... package - package_id - package_name (unique) - repository_id ... This makes it easy for me to see, for example, what are valid versions of a given package: I can join with the version table using the repository_id. However, suppose I would like to add some information to this database, e.g., to indicate which package versions have been approved for release. I certainly need a new table: package_version - version_id - package_id - package_version_released ... Again, the nature of the keys that I use are not really important to my problem, and you can imagine that the data column is "promotion_level" or something if that helps. My doubts arise when I realize that there's really a very close relationship between the version_id and the package_id in my new table ... they must share the same repository_id. Only a small subset of package/version combinations are valid. So I should have some kind of constraint on those columns, enforcing that ... ... I don't know, it just feels off, somehow. Like I'm including somehow more information than I really need? I don't know how to explain my hesitance here. I can't figure out which (if any) normal form I'm violating, but I also can't find an example of a schema with this sort of structure ... not being a DBA by profession I'm not sure where to look. So I'm asking: am I just being overly sensitive?

  • What .NET serializers have fixed size output for a given class?

    - by Jader Dias
    XML based serializers have variable size output for a given class. I can't use them to append data to my Memcached list, since I won't be able to retrieve that information later. But if I knew my serializer produced a fixed size output (N bytes), I could retrieve my data by splitting my list in N bytes chunks and then deserializing those chunks individually. I have created my own serializer for my class, but what other serializers I could use?

  • Using data from a dataset in styles with Mapnik

    - by Alex King
    I've setup Mapnik to connect to a PostGIS database, and display geometry. I'd like to have a column in my database called opacity, and use it as the opacity for that row of geometry when Mapnik renders it. So far, I've only found information on how to display text from the database, and how to use filters to display different styles when database values are within parameters. Nothing about how to use the values directly inside of a style or layer though - is this possible?

  • How to get width of button in DateTimePicker-Control/Controls in general?

    - by Inno
    Hello everybody, I implemented a custom DateTimePicker. On the DateTimePicker there is a button. In the examples I've found it's width is set to 16. This is working but I would like to have a dynamic approach. So, is there a way to get the size of this button or is there a general way to get information about .Net-Control sub elements like size etc.? Trying DateTimePicker.Controls didn't help me (it's empty).

  • Does a lazy-programmer "document template" with tags exist for Windows?

    - by Anthony Forloney
    I was wondering (if possible) if there was a program/tool/utility that when I create a new file and provide it with an extension that it creates the tags automatically? For example, a new file I create called index.php would have the appropriate tags auto-generated inside: <?php ?> I hope you get the idea. Does one, or could one, exist, preferably Windows based? Any information regarding this would be helpful.

  • BizTalk - generating schema from Oracle stored proc with table variable argument

    - by Ron Savage
    I'm trying to set up a simple example project in BizTalk that gets changes made to a table in a SQL Server db and updates a copy of that table in an Oracle db. On the SQL Server side, I have a stored proc named GetItemChanges() that returns a variable number of records. On the Oracle side, I have a stored proc named Update_Item_Region_Table() designed to take a table of records as a parameter so that it can process all the records returned from GetItemChanges() in one call. It is defined like this: create or replace type itemrec is OBJECT ( UPC VARCHAR2(15), REGION VARCHAR2(5), LONG_DESCRIPTION VARCHAR2(50), POS_DESCRIPTION VARCHAR2(30), POS_DEPT VARCHAR2(5), ITEM_SIZE VARCHAR2(10), ITEM_UOM VARCHAR2(5), BRAND VARCHAR2(10), ITEM_STATUS VARCHAR2(5), TIME_STAMP VARCHAR2(20), COSTEDBYWEIGHT INTEGER ); create or replace type tbl_of_rec is table of itemrec; create or replace PROCEDURE Update_Item_Region_table ( Item_Data tbl_of_rec ) IS errcode integer; errmsg varchar2(4000); BEGIN for recIndex in 1 .. Item_Data.COUNT loop update FL_ITEM_REGION_TEST set Region = Item_Data(recIndex).Region, Long_description = Item_Data(recIndex).Long_description, Pos_Description = Item_Data(recIndex).Pos_description, Pos_Dept = Item_Data(recIndex).Pos_dept, Item_Size = Item_Data(recIndex).Item_Size, Item_Uom = Item_Data(recIndex).Item_Uom, Brand = Item_Data(recIndex).Brand, Item_Status = Item_Data(recIndex).Item_Status, Timestamp = to_date(Item_Data(recIndex).Time_stamp, 'yyyy-mm-dd HH24:mi:ss'), CostedByWeight = Item_Data(recIndex).CostedByWeight where UPC = Item_Data(recIndex).UPC; log_message(Item_Data(recIndex).Region, '', 'Updated item ' || Item_Data(recIndex).UPC || '.'); end loop; EXCEPTION WHEN OTHERS THEN errcode := SQLCODE(); errmsg := SQLERRM(); log_message('CE', '', 'Error in Update_Item_Region_table(): Code [' || errcode || '], Msg [' || errmsg || '] ...'); END; In my BizTalk project I generate the schemas and binding information for both stored procedures. For the Oracle procedure, I specified a path for the GeneratedUserTypesAssemblyFilePath parameter to generate a DLL to contain the definition of the data types. In the Send Port on the server, I put the path to that Types DLL in the UserAssembliesLoadPath parameter. I created a map to translate the GetItemChanges() schema to the Update_Item_Region_Table() schema. When I run it the data is extracted and transformed fine but causes an exception trying to pass the data to the Oracle proc: *The adapter failed to transmit message going to send port "WcfSendPort_OracleDBBinding_HOST_DATA_Procedure_Custom" with URL "oracledb://dvotst/". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.InvalidOperationException: Custom type mapping for 'HOST_DATA.TBL_OF_REC' is not specified or is invalid.* So it is apparently not getting the information about the custom data type TBL_OF_REC into the Types DLL. Any tips on how to make this work?

  • How to activate revision info in line number view

    - by Joshua
    I know of an Eclipse feature to show revision information (gradual coloring, more info like revisionnumber, date and author on mouseover) for the last changes in a line in the linenumbers-view. Does anyone know how to activate this feature for a file, or even better, by default? I accidently hit some shortcut lately which made it show in one file, it does not show up in the others, though.

  • Find out why Xcode has decided to link to a particular library

    - by andygeers
    I'm using the Unity 3D engine to build an iPhone app, and when I go to generate my Xcode project for compilation, it includes a few fairly large libraries: Mono.Security.dll.s, System.dll.s, System.Core.dll.s, etc. I don't know if this question is really an Xcode question or a Unity question, but I'm trying to figure out why each of those libraries is being linked - which functions / classes are being referenced - ideally so that I can rewrite my code to remove as many of the dependencies as possible. Does anybody know a way to find this information out?

  • Get total size of all Shared Folders (Except Admin Shares) from a list of Servers?

    - by bEUY
    Hi there, I'm looking to calculate the total size of all shared folders (except admin shares) on a number of different servers (consolidating all accessed files to a NAS box for easier backup / restore) but am having a bit of trouble finding a solution. I'm certain this could be done in powershell but I just can't find the right information to get me going, I can currently spit out a list of all shares on the servers but am not sure where to go from here: $servers =@( "server1", "server2") foreach($server in $servers) { get-WmiObject Win32_Share -computerName $server -filter "Type = 0" }

  • Dubugging a program not run within the debugger and without a crash

    - by Mick
    I left a program running last night, it worked fine for about 5 hours and then one of its built-in self-diagnostic tests detected a problem and brought up a dialog box telling me the issue. The program was built with debug information (/Zi). Is it possible to somehow get the debugger started so I can examine the value of some variables within the program? Or is it too late?

  • Remove never-run call to templated function, get allocation error on run-time

    - by Narfanator
    First off, I'm a bit at a loss as to how to ask this question. So I'm going to try throwing lots of information at the problem. Ok, so, I went to completely redesign my test project for my experimental core library thingy. I use a lot of template shenanigans in the library. When I removed the "user" code, the tests gave me a memory allocation error. After quite a bit of experimenting, I narrowed it down to this bit of code (out of a couple hundred lines): void VOODOO(components::switchBoard &board){ board.addComponent<using_allegro::keyInputs<'w'> >(); } Fundementally, what's weirding me out is that it appears that the act of compiling this function (and the template function it then uses, and the template functions those then use...), makes this bug not appear. This code is not being run. Similar code (the same, but for different key vals) occurs elsewhere, but is within Boost TDD code. I realize I certainly haven't given enough information for you to solve it for me; I tried, but it more-or-less spirals into most of the code base. I think I'm most looking for "here's what the problem could be", "here's where to look", etc. There's something that's happening during compile because of this line, but I don't know enough about that step to begin looking. Sooo, how can a (presumably) compilied, but never actually run, bit of templated code, when removed, cause another part of code to fail? Error: Unhandled exceptionat 0x6fe731ea (msvcr90d.dll) in Switchboard.exe: 0xC0000005: Access violation reading location 0xcdcdcdc1. Callstack: operator delete(void * pUser Data) allocator< class name related to key inputs callbacks ::deallocate vector< same class ::_Insert_n(...) vector< " " ::insert(...) vector<" "::push_back(...) It looks like maybe the vector isn't valid, because _MyFirst and similar data members are showing values of 0xcdcdcdcd in the debugger. But the vector is a member variable...

  • Integration Services Throws an Error Reading Access 2007 Table

    - by Eric Flamm
    [Participant Table [1994]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "I:\My Documents\Flamm Consulting\Migrations.accdb" failed with error code 0xC0209303. There may be error messages posted before this with more information on why the AcquireConnection method call failed. Frankly, I'm confused about how SSIS should connect to Access 2007 - the UI just isn't very friendly - there's no file browser, for example. I'm wondering if there's something wrong with my install - missing drivers, etc.
