• OpenGl texture mapping blocking colours on FreeType?

  - by Dororo

  I'm using FreeType in order to allow fonts to be used in OpenGL. However, I'm having a problem where I cannot change the font colour whenever I do texture mapping. No matter what I select using glColor3f it will just come out white. The texture works fine. glClear(GL_COLOR_BUFFER_BIT); glLoadIdentity(); glColor3f(0.5,0.0,0.5); glPushMatrix(); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); glEnable(GL_TEXTURE_2D); glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE); glBindTexture(GL_TEXTURE_2D, texName); glBegin(GL_POLYGON); glTexCoord2f(0,1); glVertex2f(-16,-16); glTexCoord2f(0,0); glVertex2f(-16,16); glTexCoord2f(1,0); glVertex2f(16,16); glTexCoord2f(1,1); glVertex2f(16,-16); glEnd(); glDisable(GL_TEXTURE_2D); glDisable(GL_BLEND); glPopMatrix(); glColor3f(1,0,0); print(our_font, -300+screenWidth/2.0, screenHeight/2.0, "fifty two - %7.2f", spin); This is the problem code, I can confirm that drawing a polygon beneath this code will indeed make it red. The text is not changing to red though which it should; if you remove the texture mapping above it will turn red again, I can only think it is a problem with enabling and disabling and I've forgotten to do something...?

• NHibernate slow mapping

  - by Rob A

  My question is what can I do to determine the cause of the slowness, or what can I do to speed it up without knowing the exact cause. I am running a simple query and it appears that the mapping back to the entities is taking taking forever. The result set is 350, which is not much data in my opinion. IRepository repo = ObjectFactory.GetInstance<IRepository>(); var q = repo.Query<Order>(item => item.Ordereddate > DateTime.Now.AddDays(-40)); foreach (var order in q) { Console.WriteLine(order.TransactionNumber); } The profiler is telling me it is executing the query 7ms / 35257ms, I am assuming that the former is the actual response from the db and the latter is the time it takes NH to do it's magic. 35 seconds is too long. This is a simple mapping, one table, nested components, using fluent interface to do mappings. I just start up a simple console app and run the one query, the slowness is measured after the SessionFactory is initialized, there should only be one session, and I am not using a transaction. Thanks

• Mapping enum with fluent nhibernate

  - by Puneet

  I am following the http://wiki.fluentnhibernate.org/Getting%5Fstarted tutorial to create my first NHibernate project with Fluent NHibernate I have 2 tables 1) Account with fields Id AccountHolderName AccountTypeId 2) AccountType with fields Id AccountTypeName Right now the account types can be Savings or Current So the table AccountTypes stores 2 rows 1 - Savings 2 - Current For AccoutType table I have defined enum public enum AccountType { Savings=1, Current=2 } For Account table I define the entity class public class Account { public virtual int Id {get; private set;} public virtual string AccountHolderName {get; set;} public virtual string AccountType {get; set;} } The fluent nhibernate mappings are: public AgencyMap() { Id(o => o.Id); Map(o => o.AccountHolderName); Map(o => o.AccountType); } When I try to run the solution, it gives an exception - InnerException = {"(XmlDocument)(2,4): XML validation error: The element 'class' in namespace 'urn:nhibernate-mapping-2.2' has incomplete content. List of possible elements expected: 'meta, subselect, cache, synchronize, comment, tuplizer, id, composite-id' in namespace 'ur... I guess that is because I have not speciofied any mapping for AccountType. The questions are: How can I use AccountType enum instead of a AccountType class? Maybe I am going on wrong track. Is there a better way to do this? Thanks!

• LinQ XML mapping to a generic type

  - by Manuel Navarro

  I´m trying to use an external XML file to map the output from a stored procedure into an instance of a class. The problem is that my class is of a generic type: public class MyValue<T> { public T Value { get; set; } } Searching through a lot of blogs an articles I've managed to get this: <?xml version="1.0" encoding="utf-8" ?> <Database Name="" xmlns="http://schemas.microsoft.com/linqtosql/mapping/2007"> <Table Name="MyValue" Member="MyNamespace.MyValue`1" > <Type Name="MyNamespace.MyValue`1"> <Column Name="Category" Member="Value" DbType="VarChar(100)" /> </Type> </Table> <Function Method="GetResourceCategories" Name="myprefix_GetResourceCategories" > <ElementType Name="MyNamespace.MyValue`1"/> </Function> </Database> The MyNamespace.MyValue`1 trick works fine, and the class is recognized. I expect four rows from the stored procedure, and I'm getting four MyValue<string> instances, but the big problem is that the property Value for the all four instances is null. The property is not getting mapped and I don't really get why. Maybe worth noting that the property Value is generic, and that when the mapping is done using attributes it works perfect. Anyone have a clue? BTW the method GetResourceCategories: public ISingleResult<MyValue<string>> GetResourceCategories() { IExecuteResult result = this.ExecuteMethodCall( this, (MethodInfo)MethodInfo.GetCurrentMethod()); return (ISingleResult<MyValue<string>>)result.ReturnValue; }

• NHibernate / Fluent - Mapping multiple objects to single lookup table

  - by Al

  Hi all I am struggling a little in getting my mapping right. What I have is a single self joined table of look up values of certain types. Each lookup can have a parent, which can be of a different type. For simplicities sake lets take the Country and State example. So the lookup table would look like this: Lookups Id Key Value LookupType ParentId - self joining to Id base class public class Lookup : BaseEntity { public Lookup() {} public Lookup(string key, string value) { Key = key; Value = value; } public virtual Lookup Parent { get; set; } [DomainSignature] [NotNullNotEmpty] public virtual LookupType LookupType { get; set; } [NotNullNotEmpty] public virtual string Key { get; set; } [NotNullNotEmpty] public virtual string Value { get; set; } } The lookup map public class LookupMap : IAutoMappingOverride<DBLookup> { public void Override(AutoMapping<Lookup> map) { map.Table("Lookups"); map.References(x => x.Parent, "ParentId").ForeignKey("Id"); map.DiscriminateSubClassesOnColumn<string>("LookupType").CustomType(typeof(LookupType)); } } BASE SubClass map for subclasses public class BaseLookupMap : SubclassMap where T : DBLookup { protected BaseLookupMap() { } protected BaseLookupMap(LookupType lookupType) { DiscriminatorValue(lookupType); Table("Lookups"); } } Example subclass map public class StateMap : BaseLookupMap<State> { protected StateMap() : base(LookupType.State) { } } Now I've almost got my mappings set, however the mapping is still expecting a table-per-class setup, so is expecting a 'State' table to exist with a reference to the states Id in the Lookup table. I hope this makes sense. This doesn't seem like an uncommon approach when wanting to keep lookup-type values configurable. Thanks in advance. Al

• Association Mapping Details confusion?

  - by AaronLS

  I have never understood why the associations in EntityFramework look the way they do in the Mapping Details window. When I select the line between 2 tables for an association, for example FK_ApplicationSectionsNodes_FormItems, it shows this: Association Maps to ApplicationSectionNodes FormItems (key symbol) FormItemId:Int32 <--> FormItemId:int ApplicationSectionNodes (key symbol) NodeId:Int32 <--> (key symbol) NodeId : int Fortunately this one was create automatically for me based on the foreign key constraints in my database, but whenever no constraints exist, I have a hard to creating associations manually(when the database doesn't have a diagram setup) because I don't understand the mapping details for associations. FormItems table has a primary key identity column FormItemId, and ApplicationSectionNodes contains a FormItemId column that is the foreign key and has NodeId as a primary key identity column. What really makes no sense to me is why the association has anything listed about the NodeId, when NodeId doesn't have anything to do with the foreign key relationship? (It's even more confusing with self referencing relationships, but maybe if I could understand the above case I'd have a better handle). CREATE TABLE [dbo].[ApplicationSectionNodes]( [NodeID] [int] IDENTITY(1,1) NOT NULL, [OutlineText] [varchar](5000) NULL, [ParentNodeID] [int] NULL, [FormItemId] [int] NULL, CONSTRAINT [PK_ApplicationSectionNodes] PRIMARY KEY CLUSTERED ( [NodeID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY], CONSTRAINT [UQ_ApplicationSectionNodesFormItemId] UNIQUE NONCLUSTERED ( [FormItemId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[ApplicationSectionNodes] WITH NOCHECK ADD CONSTRAINT [FK_ApplicationSectionNodes_ApplicationSectionNodes] FOREIGN KEY([ParentNodeID]) REFERENCES [dbo].[ApplicationSectionNodes] ([NodeID]) GO ALTER TABLE [dbo].[ApplicationSectionNodes] NOCHECK CONSTRAINT [FK_ApplicationSectionNodes_ApplicationSectionNodes] GO ALTER TABLE [dbo].[ApplicationSectionNodes] WITH NOCHECK ADD CONSTRAINT [FK_ApplicationSectionNodes_FormItems] FOREIGN KEY([FormItemId]) REFERENCES [dbo].[FormItems] ([FormItemId]) GO ALTER TABLE [dbo].[ApplicationSectionNodes] NOCHECK CONSTRAINT [FK_ApplicationSectionNodes_FormItems] GO FormItems Table: CREATE TABLE [dbo].[FormItems]( [FormItemId] [int] IDENTITY(1,1) NOT NULL, [FormItemType] [int] NULL, CONSTRAINT [PK_FormItems] PRIMARY KEY CLUSTERED ( [FormItemId] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO ALTER TABLE [dbo].[FormItems] WITH NOCHECK ADD CONSTRAINT [FK_FormItems_FormItemTypes] FOREIGN KEY([FormItemType]) REFERENCES [dbo].[FormItemTypes] ([FormItemTypeId]) GO ALTER TABLE [dbo].[FormItems] NOCHECK CONSTRAINT [FK_FormItems_FormItemTypes] GO

• "Function object is unsubscriptable" in basic integer to string mapping function

  - by IanWhalen

  I'm trying to write a function to return the word string of any number less than 1000. Everytime I run my code at the interactive prompt it appears to work without issue but when I try to import wordify and run it with a test number higher than 20 it fails as "TypeError: 'function' object is unsubscriptable". Based on the error message, it seems the issue is when it tries to index numString (for example trying to extract the number 4 out of the test case of n = 24) and the compiler thinks numString is a function instead of a string. since the first line of the function is me defining numString as a string of the variable n, I'm not really sure why that is. Any help in getting around this error, or even just help in explaining why I'm seeing it, would be awesome. def wordify(n): # Convert n to a string to parse out ones, tens and hundreds later. numString = str(n) # N less than 20 is hard-coded. if n < 21: return numToWordMap(n) # N between 21 and 99 parses ones and tens then concatenates. elif n < 100: onesNum = numString[-1] ones = numToWordMap(int(onesNum)) tensNum = numString[-2] tens = numToWordMap(int(tensNum)*10) return tens+ones else: # TODO pass def numToWordMap(num): mapping = { 0:"", 1:"one", 2:"two", 3:"three", 4:"four", 5:"five", 6:"six", 7:"seven", 8:"eight", 9:"nine", 10:"ten", 11:"eleven", 12:"twelve", 13:"thirteen", 14:"fourteen", 15:"fifteen", 16:"sixteen", 17:"seventeen", 18:"eighteen", 19:"nineteen", 20:"twenty", 30:"thirty", 40:"fourty", 50:"fifty", 60:"sixty", 70:"seventy", 80:"eighty", 90:"ninety", 100:"onehundred", 200:"twohundred", 300:"threehundred", 400:"fourhundred", 500:"fivehundred", 600:"sixhundred", 700:"sevenhundred", 800:"eighthundred", 900:"ninehundred", } return mapping[num] if __name__ == '__main__': pass

• Simple Fluent NHibernate Mapping Problem

  I have the following tables I need to map: +-------------------------+ | Person | +-------------------------+ | PersonId | | FullName | +-------------------------+ +-------------------------+ | PersonAddress | +-------------------------+ | PersonId | | AddressId | | IsDefault | +-------------------------+ +-------------------------+ | Address | +-------------------------+ | AddressId | | State | +-------------------------+ And the following classes: public class Person { public virtual int Id { get; set; } public virtual string FullName { get; set; } } public class PersonAddress { public virtual Person Person { get; set; } public virtual Address Address { get; set; } public virtual bool IsDefault { get; set; } } public class Address { public virtual int Id { get; set; } public virtual string State { get; set; } } And finally the mappings: public class PersonMap : ClassMap<Person> { public PersonMap() { Id(x => x.Id, "PersonId"); } } public class PersonAddressMap : ClassMap<PersonAddress> { public PersonAddressMap() { CompositeId().KeyProperty(x => x.Person, "PersonID") .KeyProperty(x => x.Address, "AddressID"); } } public class AddressMap: ClassMap<Address> { public AddressMap() { Id(x => x.Id, "AddressId"); } } Assume I cannot alter the tables. If I take the mapping class (PersonAddress) out of the equation, everything works fine. If I put it back in I get: Could not determine type for: Person, Person, Version=1.0, Culture=neutral, PublicKeyToken=null, for columns: NHibernate.Mapping.Column(PersonId) What am I missing here? I'm sure this must be simple.

• Check for existing mapping when writing a custom applier in ConfORM

  - by Philip Fourie

  I am writing my first custom column name applier for ConfORM. How do I check if another column has already been map with same mapping name? This is what I have so far: public class MyColumnNameApplier : IPatternApplier<PropertyPath, IPropertyMapper> { public bool Match(PropertyPath subject) { return (subject.LocalMember != null); } public void Apply(PropertyPath subject, IPropertyMapper applyTo) { string shortColumnName = ToOracleName(subject); // How do I check if the short columnName already exist? applyTo.Column(cm => cm.Name(shortColumnName)); } private string ToOracleName(PropertyPath subject) { ... } } } I need to shorten my class property names to less than 30 characters to fit in with Oracle's 30 character limit. Because I am shortening the column names it is possible that I generate the same name for two different properties. I would like to know when a duplicate mapping occurs. If I don't handle this scenario ConfORM/NHibernate allows two different properties to 'share' the same column name - this is obviously creates a problem for me.

• Hibernate - EhCache - Which region to Cache associations/sets/collections ??

  - by lifeisnotfair

  Hi all, I am a newcomer to hibernate. It would be great if someone could comment over the following query that i have: Say i have a parent class and each parent has multiple children. So the mapping file of parent class would be something like: parent.hbm.xml <hibernate-mapping > <class name="org.demo.parent" table="parent" lazy="true"> <cache usage="read-write" region="org.demo.parent"/> <id name="id" column="id" type="integer" length="10"> <generator class="native"> </generator> </id> <property name="name" column="name" type="string" length="50"/> <set name="children" lazy="true"> <cache usage="read-write" region="org.demo.parent.children" /> <key column="parent_id"/> <one-to-many class="org.demo.children"/> </set> </class> </hibernate-mapping> children.hbm.xml <hibernate-mapping > <class name="org.demo.children" table="children" lazy="true"> <cache usage="read-write" region="org.demo.children"/> <id name="id" column="id" type="integer" length="10"> <generator class="native"> </generator> </id> <property name="name" column="name" type="string" length="50"/> <many-to-one name="parent_id" column="parent_id" type="integer" length="10" not-null="true"/> </class> </hibernate-mapping> So for the set children, should we specify the region org.demo.parent.children where it should cache the association or should we use the cache region of org.demo.children where the children would be getting cached. I am using EHCache as the 2nd level cache provider. I tried to search for the answer to this question but couldnt find any answer in this direction. It makes more sense to use org.demo.children but I dont know in which scenarios one should use a separate cache region for associations/sets/collections as in the above case. Kindly provide your inputs also let me know if I am not clear in my question. Thanks all.

• Applying the Hibernate filter attribute to a Bag with a many-to-many relationship

  - by David P

  Consider the following Hibernate mapping file: <hibernate-mapping ...> <class name="ContentPackage" table="contentPackages"> <id name="Id" column="id" type="int"><generator class="native" /></id> ... <bag name="Clips" table="contentAudVidLinks"> <key column="fk_contentPackageId"></key> <many-to-many class="Clip" column="fk_AudVidId"></many-to-many> <filter name="effectiveDate" condition=":asOfDate BETWEEN startDate and endDate" /> </bag> </class> </hibernate-mapping> When I run the following command: _session.EnableFilter("effectiveDate").SetParameter("asOfDate", DateTime.Today); IList<ContentPackage> items = _session.CreateCriteria(typeof(ContentPackage)) .Add(Restrictions.Eq("Id", id)) .List<ContentPackage>(); The resulting SQL has the WHERE clause on the intermediate mapping table (contentAudVidLinks), rather than the "Clips" table even though I have added the filter attribute to the Bag of Clips. What am I doing wrong?

• Migrating from a single entity to an abstract parent entity with child entities, NSEntityMigrationPolicy not called.

  Hi. I'm trying to upgrade my current application to use an abstract parent entity, with specialized sub entities. I've created a custom NSEntityMigrationPolicy, and in the mapping model I've set the Custom Policy to the name of my class. I'm initializing my persistent store like this, which should be fairly standard : NSError *error=nil; persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]]; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, nil]; if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { NSLog(@"Error adding persistent store : %@",[error description]); NSAssert(error==nil,[error localizedDescription]); } When i run the app i get the following error : Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The operation couldn’t be completed. (Cocoa error 134140.)' [error userInfo] contains "reason=Can't find mapping model for migration" I've verified that version 1 of the data model will open, and if i set NSInferMappingModelAutomaticallyOption i get a migration, although my entities are not migrated correctly (as expected). I've verified that the mapping model (cdm) is in the application bundle, but somehow it refuses to find it. I've also set breakpoints and NSLog() statements in the custom migration policy, and none of it runs, with or without NSInferMappingModelAutomaticallyOption Any hints as to why it seems unable to find the mapping model ?

• How to Map Two Tables To One Class in Fluent NHibernate

  - by Richard Nagle

  I am having a problem with fluent nhiberbate mapping two tables to one class. I have the following database schema: TABLE dbo.LocationName ( LocationId INT PRIMARY KEY, LanguageId INT PRIMARY KEY, Name VARCHAR(200) ) TABLE dbo.Language ( LanguageId INT PRIMARY KEY, Locale CHAR(5) ) And want to build the following class definition: public class LocationName { public virtual int LocationId { get; private set; } public virtual int LanguageId { get; private set; } public virtual string Name { get; set; } public virtual string Locale { get; set; } } Here is my mapping class: public LocalisedNameMap() { WithTable("LocationName"); UseCompositeId() .WithKeyProperty(x => x.LanguageId) .WithKeyProperty(x => x.LocationId); Map(x => x.Name); WithTable("Language", lang => { lang.WithKeyColumn("LanguageId"); lang.Map(x => x.Locale); }); } The problem is with the mapping of the Locale field being from another table, and in particular that the keys between those tables don't match. Whenever I run the application with this mapping I get the following error on startup: Foreign key (FK7FC009CCEEA10EEE:Language [LanguageId])) must have same number of columns as the referenced primary key (LocationName [LanguageId, LocationId]) How do I tell nHibernate to map from LocationName to Language using only the LanguageId field?

• Nhibernate:null index column for collection Error

  - by Quintin Par

  I am working a subsonic to NH migration(I can’t change the schema) and while creating the mapping I came across this error null index column for collection: Company.Core.CompanyUser.Addresses My mapping from the User side is mapping.HasMany(x => x.Addresses).AsList().KeyColumn("user_id").Cascade.All().Inverse(); xml <list cascade="all" inverse="true" name="Addresses"> <key> <column name="user_id" /> </key> <index /> <one-to-many class="Company.Core.CompanyAddress, Company.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </list> On the Address side it is mapping.CompositeId().KeyReference(x => x.User, "user_id").KeyProperty(x => x.Type); xml <composite-id mapped="false" unsaved-value="undefined"> <key-property name="Type" type="System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"> <column name="Type" /> </key-property> <key-many-to-one name="User" class="Company.Core.CompanyUser, Company.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"> <column name="user_id" /> </key-many-to-one> </composite-id> When I try to load this collection as user.Addresses I get the index null exception. How do I fix this error?

• IIS6 Wildcard Mapping to ASP.NET - no file extension results in IIS 404

  - by Ian Robinson

  I'm trying to perform what I understand to be a relatively simple task. I'd like to remove the extensions from the URLs on my website. I have the proper set up in my application to handle and rewrite the URLs - the trouble is I can't get past IIS to actually get to my application without the extensions. The details: I'm running IIS6 on Windows Server 2003. I've gone into the web site for my application, gone to the home directory tab, clicked "Configuration" and added a wildcard map to the following file: c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll Which I verified is the same as what is used above in the application extensions portion by .ascx, etc. If I navigate to http://mywebsite.com/Blogs the result is as follows: HTTP/1.1 404 Not Found Content-Length: 1635 Content-Type: text/html Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET Date: Thu, 14 Jan 2010 15:04:49 GMT Which seems to be a standard IIS 404 message. If I navigate to http://mywebsite.com/Blogs.aspx I get my ASP.NET app.... How can I troubleshoot this? I feel like I've double checked everything a dozen times but to no avail. I must be missing something obvious. Update: Here are the exact instructions given by the asp.net url rewriter that I'm using: IIS 6.0 - Windows 2003 Server open property page for website / virtual directory. click the 'home directory' tab click the 'configuration' button, select the 'mappings' tab click 'insert' next to the 'Wildcard application maps' section browse to the aspnet_isapi.dll (normally at c:\windows\microsoft.net\framework\v2.0.50727\aspnet_isapi.dll) Ensure that 'check that file exists' is unchecked Click OK, OK, OK to close and apply changes Update 2: I have yet to find a resolution for this. The application does not seem to be receiving the request from IIS, any further ideas?

• SSRS 2008 & MOSS 2007 Alternate Access Mapping Problem

  - by Mauro

  I have a MOSS Server with SSRS 2008 Ent Ed configured in Sharepoint Integrated mode. It all works well as http://servername:88/ on the default host header. MOSS works fine using the external host name too on the intranet AAM field (http://site.domain.com/) however SSRS fails on the same url with the message: An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. I think the issue is further complicated by our Windows 2008 infrastructure in which we've never been able to get SPN's working for Kerberos. SQL Server however, is on the same machine so I dont think it is a kerberos double hop issue. Extra info MOSS/SSRS are on a VM running Windows 2003 R2 VM is hosted on Win2008 HyperV DC is on Windows 2008 SBS

• Mapping Left Alt key in vim?

  - by Yogesh Arora

  I am able to map the key combination Right Alt+Left Arrow with <a-left> or by <m-left>. But I am not able to map the Left Alt key. Is there a way to do that? Edit: Just to clarity <a-left> means Alt+Left Arrow. The important question here is what is difference between Left Alt and Right Alt from the perspective of keymappings in Vim?

• How can I sort out Xephyr's keyboard mapping?

  - by qedi

  When I start up Xephyr inside of X, my keyboard map becomes wonky mostly just for non-printing characters. I can't use arrow keys. According to xev, The down arrow gets mapped to Super_R. The up arrow is Print Screen. PgDown is mapped to "Menu". My keyboard works fine in the original X display (:0), but in the Xephyr subdisplay (:1), nothing else quite works right. I don't have any funky xmodmap things going on in my main X display that I'm aware of. All I really do is setxkbmap -option ctrl:swapcaps.

• Synergy 1.4.2 Linux server, OSX client, Media/Function key mapping issues

  - by at165dB

  I'm using an Apple bluetooth keybord to control my Linux synergy server. SSH tunneling, Mouse, Keyboard, and Copy&Paste all work. Linux sees all the media/app keys that are on top of the F# keys correctly. However if I press any of those keys while controlling my OSX client, nothing happens on the client. Running synergys with -d DEBUG1 I can see the following keycode info: Pressing the "dim monitor" key that also serves as F1 generates: new mask: 0x2000 event: KeyPress code=232, state=0x0010 new mask: 0x2000 If I press "fn" and the same key, I can see it sending what I'm assuming is an F1: event: KeyPress code=67, state=0x0010 onKeyDown id=61374 mask=0x2000 button=0x0043 send key down to "foo.cisco.com" id=61374, mask=0x2000, button=0x0043 new mask: 0x2000 event: KeyRelease code=67, state=0x0010 onKeyUp id=61374 mask=0x2000 button=0x0043 send key up to "foo.cisco.com" id=61374, mask=0x2000, button=0x0043 I'm guessing I need to tweak my synergy.conf so that the server sends keys that it currently isn't. I'm also not sure what I need to do to tweak the keys that it is sending, but are not working. Below are all the other keys I'm having issues with. Does anyone have any idea how I can enable their functionality? brighten monitor: new mask: 0x2000 event: KeyPress code=233, state=0x0010 new mask: 0x2000 expose: new mask: 0x2000 event: KeyPress code=128, state=0x0010 new mask: 0x2000 dashboard: new mask: 0x2000 event: KeyPress code=212, state=0x0010 new mask: 0x2000 dim keyboard: new mask: 0x2000 event: KeyPress code=237, state=0x0010 new mask: 0x2000 brighten keyboard: new mask: 0x2000 event: KeyPress code=238, state=0x0010 new mask: 0x2000 rewind: event: KeyPress code=173, state=0x0010 onKeyDown id=57521 mask=0x2000 button=0x00ad send key down to "foo.cisco.com" id=57521, mask=0x2000, button=0x00ad new mask: 0x2000 event: KeyRelease code=173, state=0x0010 onKeyUp id=57521 mask=0x2000 button=0x00ad send key up to "foo.cisco.com" id=57521, mask=0x2000, button=0x00ad play/pause: event: KeyPress code=172, state=0x0010 onKeyDown id=57523 mask=0x2000 button=0x00ac send key down to "foo.cisco.com" id=57523, mask=0x2000, button=0x00ac new mask: 0x2000 event: KeyRelease code=172, state=0x0010 onKeyUp id=57523 mask=0x2000 button=0x00ac send key up to "foo.cisco.com" id=57523, mask=0x2000, button=0x00ac fastforward: event: KeyPress code=171, state=0x0010 onKeyDown id=57520 mask=0x2000 button=0x00ab send key down to "foo.cisco.com" id=57520, mask=0x2000, button=0x00ab new mask: 0x2000 event: KeyRelease code=171, state=0x0010 onKeyUp id=57520 mask=0x2000 button=0x00ab send key up to "foo.cisco.com" id=57520, mask=0x2000, button=0x00ab mute: event: KeyPress code=121, state=0x0010 onKeyDown id=57517 mask=0x2000 button=0x0079 send key down to "foo.cisco.com" id=57517, mask=0x2000, button=0x0079 new mask: 0x2000 event: KeyRelease code=121, state=0x0010 onKeyUp id=57517 mask=0x2000 button=0x0079 send key up to "foo.cisco.com" id=57517, mask=0x2000, button=0x0079 volume down: onKeyDown id=57518 mask=0x2000 button=0x007a send key down to "foo.cisco.com" id=57518, mask=0x2000, button=0x007a new mask: 0x2000 event: KeyRelease code=122, state=0x0010 onKeyUp id=57518 mask=0x2000 button=0x007a send key up to "foo.cisco.com" id=57518, mask=0x2000, button=0x007a volume up: event: KeyPress code=123, state=0x0010 onKeyDown id=57519 mask=0x2000 button=0x007b send key down to "foo.cisco.com" id=57519, mask=0x2000, button=0x007b new mask: 0x2000 event: KeyRelease code=123, state=0x0010 onKeyUp id=57519 mask=0x2000 button=0x007b send key up to "foo.cisco.com" id=57519, mask=0x2000, button=0x007b eject: event: KeyPress code=169, state=0x0010 onKeyDown id=57345 mask=0x2000 button=0x00a9 send key down to "foo.cisco.com" id=57345, mask=0x2000, button=0x00a9 new mask: 0x2000 event: KeyRelease code=169, state=0x0010 onKeyUp id=57345 mask=0x2000 button=0x00a9 send key up to "foo.cisco.com" id=57345, mask=0x2000, button=0x00a9

• Error adding 4tb LUN (Raw Device Mapping) to ESX4 VM

  - by Tom Gardiner

  Hi guys, I'm trying to map an existing 4tb LUN from a Fibre Channel SAN, through to a VM in my ESX4 environment. It keeps telling me that the VMDK file size exceeds the the maximum size supported by the datastore. I've tried in Physical compatibility mode, and also both Virtual styles. I'm a little confused by this as we had the same LUN mapped through to another VM when we were running ESX3.5... I've also noticed that some of my other RAW mappings are generating extremely large VMDK files on the ESX servers. Does anyone know if this change in behaviour is intentional? And if so why? It doesn't seem to me that if the LUN is mapped directly to the VM that it's size should be relevant. We're running 4.0.0 build 236512, and 4.0.0 build 219382 and I've not had any success on either. Any insight or advice would be much appreciated! TG
