[Gambas-user] Packaging - rpmbuild
Me again! :-) Houston , we have a problem! I'm not too sure how to characterise this but, I'll start along these lines: 1) I'm fairly sure that rpmbuild (and friends) depends on some pretty stable autotools stuff in the source archive. For this reason I have been harping on about getting the autotools packager right. 2) Nasty and only diagnosed tonight !-( rpmbuild looks in the packager's home dir for a couple of nicely hidden and cryptic files called .rpmrc and .rpmmacros. .rpmrc appears to contain the i-whatever architecture translates, viz: buildarchtranslate: i386: i586 buildarchtranslate: i486: i586 buildarchtranslate: i586: i586 buildarchtranslate: i686: i586 .rpmmacros on the other hand has some stuff that are important, viz %_topdir/home/bb/src/rpm %_tmppath /home/bb/src/tmp %packager paddys-hill %distribution phhorse %distsuffix ph12 %vendor Paddys-Hill_dot_Net 3) I'm pretty sure that we are using a generic and reasonably stable version of rpmbuild: [bb@bluecow ~]$ rpmbuild --version RPM version 4.8.1 asideI am aware that there are (ahem) later versions available, but not on sourceforge. (Ahem! and the changelog IMHO looks a little like a mad cow on steroids who has lost her Valium prescription.)/aside 4) We build rpm packages for our clients outside gambas. Which work. So I'm not too amendable to the idea of mucking around with these files to suit the gambas packager. 5) The problem, as far as I am able to see with my limited knowledge of rpm builds, is the (_topdir) and (_tmppath) macros. These tend to override the places that the gambas rpm builder scripts are looking for stuff, in particular the source archive. If you are still reading by now, God bless you. I've been trying to track this down for 12 hours straight. E'en more. I really would appreciate it, if you do know a heck of a lot about rpmbuild, that you let me know so we can fix this and add it back to gambas.

Re: [Gambas-user] About library and component packaging in Gambas 3
(New sub-thread) .info has disappeared If a project has its type set to Component now, when it is compiled (or Make Executable) there is no .info file created in the project directory any more. Is this by design? (Because the autotools install target is still looking for it and fails. I can help fix the autotools scripts but I need to know if .info has disappeared on purpose.)

Le 29/04/2012 06:45, Bruce Bruen a écrit : SUGGESTION: Libraries should not need to have a startup class. At the moment I must include a dummy module to prevent any test-harness code leaking into the user environment (which could cause damage if the library were to be run as a normal gambas executable.) At the moment the IDE will not let a library be made into an executable or packaged unless it has a startup class. It would be preferable that projects defined as libraries would not execute via the runtime, that way test harness code could be left in place. Currently I have to check that the coders have left the startup class pointing to the following:- ' Gambas module file ' Null module to provide a fake startup point Public Sub Main() Error Please do not run this as a program. It is a gambas library. End Mmm. You are right, for libraries the IDE should let you not defined a startup class. I will see what I can do. I think that (the IDE should let you not defined a startup class) is an overkill. What I need is a way to use a startup class in a library when I'm developing it but when it is packaged the startup class should be removeable. To explain, during development/debug/support for a library, we need to be able to run it as a normal project through the IDE. This is what I meant about test harnesses. In general, we have a MMain module in the library that may, or in fact usually, contains code that lets us enter method parameter values manually. This type of code if used by an ill-advised user could cause great havoc on an underlying database or the like. What I would like is a way to manually disable or turn off the startup class when the library project is made as an executable or is packaged. I suppose that the alternative is to not allow startup classes in libraries or components and keep changing the project type to Normal when we are debugging/supporting but I can foresee a lot of mistakes if that route is chosen. The way I see it is this. (Hypothetically) I've just spent some time on the phone to Mr Jones and it appears that there is, amazingly, a problem in the xyzzzy library. I open the xyzzy project and using the test harness code therein I find that we did in fact code a logic error when some date parameter to a dual timezone function is exactly the date and time that daylight savings changed in one of the timezones. ( I kid you not, this happened recently!) So I give the problem to the wizkids, er sorry, my brilliant development team, and they come up with a nicely tested solution. So now all I want to do is turn off the startup class, compile and make the distributable version and send it out. With a bit of thought... maybe what libraries/components need is a startup class that only works within the IDE... hmm!

Since today I have had the following happen - see the screenshot. 1) The first time I try to Make Executable in the IDE I get that blue balloon. 2) Also, as soon as a change is made to a code line that pops up the mini help, then strange things occur. For example, if I type App then the help popup appears as it should but then the busy cursor appears and never goes away, (as if Dec Application.Busy never happens in the IDE?) But! I can keep doing things, in fact anything (so far) but actually run the app from the IDE. You can see the busy cursor in the screenshot.

Final comments for now. 1) Is the previous method I posted that causes the IDE crash reproduceable? 2) in the IDE Project.module, in the LoadFile function, towards the bottom of the function is the following code: Files[sPath] = hForm If hForm Then bError = hForm.LoadFile() ==HERE! If bError Then Files[sPath] = Null Try hForm.Delete Dec Application.Busy Return Endif hForm.Icon = GetFileIcon(sPath, 16) Endif If hForm Then FSearch.OnNewForm(hForm) Dec Application.Busy Endif Return hForm 'Catch Dec Application.Busy Files[sPath] = Null FMain.ShowError((Cannot open file.) \n\n Error.Text \n Error.Where, sPath) End The issue I'm seeing occurs at the bError = hForm.LoadFile() line (line 1835 in my rev).

Re: [Gambas-user] About library and component packaging in Gambas 3
Hi Benoit, A few comments inline... regards Bruce On Sat, 2012-04-28 at 15:26 +0200, Benoît Minisini wrote: Hi, I'm continue in fixing problems in library and component packaging. Here are the last news... Since revision #4687, there is now a project type option in the project properties dialog, which allows to make the difference between a normal project, a library and a component. What are the differences between the three types? 1) LIBRARY SUGGESTION: Libraries should not need to have a startup class. At the moment I must include a dummy module to prevent any test-harness code leaking into the user environment (which could cause damage if the library were to be run as a normal gambas executable.) At the moment the IDE will not let a library be made into an executable or packaged unless it has a startup class. It would be preferable that projects defined as libraries would not execute via the runtime, that way test harness code could be left in place. Currently I have to check that the coders have left the startup class pointing to the following:- ' Gambas module file ' Null module to provide a fake startup point Public Sub Main() Error Please do not run this as a program. It is a gambas library. End - There is a library/component properties dialog. - No icon is packaged. Not sure about this as far as the autotools packager is concerned. The icon.png is certainly in the gzip file (but is this because autotools is a source level package?) - No menu entry is defined in the package. - The package name is projectname-X.Y.Z where X.Y.Z is the version. - The vendor can be added as a prefix optionally. Are there any pros and cons here? - The package has dependencies on other components and libraries checked in the project properties dialog. This is unclear. I was under the assumption that the Project Properties dialog Components and Libraries tabs indicated the items that are needed when running the library within the IDE (i.e. in test mode) and the Component Properties dialog defined the dependencies for the library when it runs as a library i.e. in another application (whether that application is running in the IDE or via gbx3). We use a few private libraries to develop and test the libraries we distribute to users and the approach I have been using is to include them in the Project Properties dialog but not the Component Properties dialog. (Again, this relates back to including test harness code in the library and perhaps Issue 123.) Could you clarify please. Further, it is unclear what the Extra Dependencies step in the RPM based packagers is for? Perhaps a little note in the header, similar to the Extra files step. 2) COMPONENT - There is a library/component properties dialog. - No icon is packaged. - No menu entry is defined in the package. - If the project has control icons, they are packaged. - The package name is gambas-vendor-projectname-X.Y.Z where X.Y.Z is the version. - The vendor prefix is mandatory, it is gb by default. - The package has no dependencies on other components and libraries. This is supposed to be managed directly by the IDE. Components are a special beast that should be included directly in Gambas sources. Again,this last bit is unclear. We use some custom control components in our product. Some of which have dependencies on native gb components, e.g. gb.db and at least one of which is dependent on another home grown component (i.e. our phDataControls component is dependent on both gb.db and our phBaseControls component. This has worked fine until now. I haven't checked this yet but does it mean that from 4687 on, that this will no longer work? 3) NORMAL PROJECT - There is no library/component properties dialog. - The make executable dialog can create a desktop shortcut automatically. - The packager has an icon and a menu entry. - The package name is ProjectName-X.Y.Z where X.Y.Z is the version. - The vendor can be added as a prefix optionally. - The package has dependencies on other components and libraries checked in the project properties dialog. Please try it and give your remarks! Regards, I have checked the autotools packaging (which is how we have hitherto been distributing our product to end users) and it works fine. I tried using the Mandriva and Fedora RPM based packaging, which allowed me to create proper looking distribution packages, but ... When I tested the installation locally I run into the following problem. There is a dependency requirement on gambas-runtime version 3.blahblah ... This makes sense except that there is no gambas-runtime for my home made system, I build and install from the source archive. Also, this is how we have set it (gambas) up on all the client's machines. Is there a way to remove this dependency from being included in the RPM package build? regards Bruce

Makes it simple and takes up only a little more space. Though it's slightly off-topic here :-) I don't hesitate to ask back here. In our environment in the firm with Win7 only running on one machine in the account office for the accounting programs and the rest running on a Linux server with LTSP and thin clients, it would be quite useful to have one of the Gambas programs for the Win7 machine. Now I have to write programs for Win and Linux if I want access to data on the server from both places. So I tried to use Virtual Box as a thin client, and it runs quite nice, but then it pauses (and seems to wait for something) every two minutes or so. This pausing lasts for 15 - 50 seconds, so the solution proved unusable. Rolf, I know a fair bit about running it the other way around (hereafter OWA), i.e. using VBox to host a windows OS on a Linux base, but not much about hosting a Linux OS on a Windows base. But here goes. The first things I would look at are: 1) Is the VBox Linux OS system drive (aka /) local to the Windows machine or is it on the LAN? I have seen something similar when I was running a set of alternate distros in VBox where their disk images were on a NFS server. I couldn't understand why, now and then, disk contention seemed to occur. 2) Another OWA issue seems to be the virtlan0 network connection (or whatever it's called). This seems to be an ongoing issue with VBox. It, in my opinion contends too much with the real network I/F's and low level things like arp. Unfortunately, I have not found a really solid solution and usually resort to killing the virtlan0 IF. (Your mileage may vary.) 3) Make sure that the virtual machine has absolutely no swap. In other words it should be able to run without any swap contention (otherwise you have it swapping into/outof it's pretend memory, then into/outof the hosting memory/swap and then, dog forbid, in and out of Microsoft's memory mismanagement system. ... In fact, this is where I would really be looking. Make sure that the VBox is grabbing the maximum possible (I'll rephrase that, the MAXIMUM POSSIBLE) memory space on the host machine. If the users complain that they cant VOIP their being-friend or can't google/face-tube/ubook etc while the accounting system batches are being posted then that is a problem that only they can solve. ... In my case, a virtual machine as a thin client is not the only way. There is a samba drive on the Linux server which serves the Windows, so I could as well start a whole Linux in Virtual Box and access that drive to fetch the data, but the terminal server is surely the more efficient way. So, all I would like to know is if you have an idea what could cause these pauses as I haven't found anything about it. Regards Rolf hth Bruce -- For Developers, A Lot Can Happen In A Second.

Does anyone have any experience with VB Studio Express ? Are there any characteristics that may be we wanted to see in Gambas3 ? Thank you ! I don't do VB, but here is one feature I would sorely appreciate. [This may be too much to ask.] I do 'frenzied' amounts of Gambas programming when on a roll, and keep hitting one brick wall often. The most common problem is knowing what objects are what and their properties and methods in an easy way that doesn't interfere with 'frenzied' programming and debugging flow. Take something like the object Application.Path which you might find in code. When I double click Application, it highlights that part of the text. When I then right click, I get a pop up menu to insert a break point, cut, paste, copy, etc. All nice. What I also want is an info menu option added to the pop up menu. Try double clicking on Application and then hitting F2 ( or even just click the cursor somewhere in Application and hit F2). If you really want it on the context menu, try Find Definition. The info menu will open a sub menu with first item titled help. If I click help, it launches a web browser of choice and a html file that documents that object. The remaining items in the sub menu is all the properties and methods of Application object can be set to, and if I click on any of those I get help on each of those sub properties. If I highlight the Path in Application.Path, and then right click, the info menu should change context to pull out help files relating to Path. Not really sure what you mean by help files relating to Path. but if the cursor is positioned in the Path part of Application.Path, then F2 (or the context menu Find Definition) brings up the help on Application.Path for me OK. The closest I can get to at the moment is to type Application. and as soon I enter the . a pop up displays all the properties and methods which allows one to guess the parameters of Application and effectively in an indirect way obtain limited help on Application object. The same scheme of info menu can be extended for all the other objects such as TextBox1.Text etc. The info menu will discover the object type that has been selected and populate the sub menus with all the correct values so that help can be obtained instantly on any object and property or method. In my opinion it will help a lot with rapid programming and debugging flow. aside ### As an aside, HTML documentation is becoming a lot easier to manage. If the HTML file is opened with konqueror, then install kompiz as well for editing the HTML file. After installing kompiz, right clicking a document in konqueror brings up a menu with option Open With . Clicking that opens a sub menu that lists kompiz. Click on the kompiz and hey presto, the HTML file is now opened for WYSIWYG editing! The edited files can be saved. So the next time you press for HTML based help through the info method, you got the most up to date help file that you personally updated with code fragments and helpful notes. Developers can contribute their personal help files back to the project. It would be good to offer the option to keep a duplicate copy of html directory as a personal html directory that does not get over written when new versions of gambas are installed. On this, I have no idea. Cheers Bruce -- Better than sec? Nothing is better than sec when it comes to monitoring Big Data applications. Try Boundary one-second resolution app monitoring today.

Well, I know only a little bit of the inner workings of Gambas, but: I've been looking to a lot of event-driven Basic dialects, and the best one, that was most widely useable: RealBasic. Why? Just because it one-click compiles to Windows/Mac/Linux. Altough, porting everything to Windows/Mac is not realistic and not desirable. This is just my opinion, so any comments are most welcome. A short list: I suppose that there exists, somewhere, in some uncharted galaxy, lifeforms that would like to see their Linux applications work on other operating systems. Me, nyah. I'm more interested in converting other operating system sufferers into Linux users and ultimately advocates. Let me explain a bit of background. I started seriously using Linux whenever it was that XP2 SP3 came out, after having used Windows since 3.0 (yes!). Until that (XP2.SP3) disaster was released I had been a true believer that Microsoft would continue to improve and enhance what appeared to be a reasonable platform for developing and deploying small business and bespoke software applications. By bespoke, I mean very niche, very specific applications that suited a small customer audience. I did some, what I consider to be nice applications using MSAccess and VBA that until about 6 years ago netted me a liveable income. When .net, asp, php, MSSQL server came out I tried porting the bases of those applications. BLUH! All I ended up with was a need to employ JUNIOR programmers to try to fix all the problems that arise from such a wide, mismanaged, buggy and IMO useless set of platforms. (Aside. These were not insignificant pieces of software, they include apps that extract and match patient details from government pathology databases and present the data for statistical analysis, apps that review and correlate mining information from aerial surveys, and a few others. The point being, they were complex and of very little use to a wide audience.) Around about 4 years ago I met a man who had a very, very specific problem. There was no software available on commercial platforms that could solve it .. in the manner that he wanted. He was a trainer of thoroughbred race horses and just wanted a program that would let him manage his horses training schedules, trials, race entries etc etc etc^99. In other words, he knew exzactly what he wanted and exzactly what he didn't want. He had been fighting to run a business for ten years, paying a large amount of money to a bunch of spreadsheet pirates and never getting that exzactly. At that time I knew exactly zero about the horse racing industry. (I reckon I now know about 2% of it :-; ) Also, co-incidentally I had just discovered Gambas 2, which looked (from my point view) like where VBA should have gone in the first place. So, I said (heroically as usual when faced by a challenge), How about I come down and see what (those exzactlies are ... and see if I can come up with a answer. Short cut to end of story. We, (private company with 4 employees) now have 36 customers. All 36 are using Linux to run their training regimes. This year, 2011-12 we are basically breaking even, and even hope ... X fingers .. to make a little profit. (Benoit, you'll be the second to know!). A few technical details: Base gambas deployment - gambas 2 (stability - around 97% (a few outstanding gb2 features still exist, but mainly we have workarounds) Code size - approx 23,000 lines. GASP! Relax, this includes comments, design notes, TODO's etc. There is, at a guess maybe 7-8 thousand executable lines, of code. Underlying database - postgresql. Do not even think of attempting to suggest something different starting with M. The database is both segmented and distributed. Each trainer can see their own data, but no-one elses. Each trainer has their own copy of their own data. The central database exists mainly as a backup for the trainers local db. It currently has over 14,000,000 rows. We do provide some views into the central db regarding public data like scheduling for trials. This includes my biggest nightmare regarding timezones, as some trainers reside in one state (timezone) and trial in another. Current projects: 1) Move EVERYTHING to gb3! 1.1) Move all clients to gb3 2) About 29 gazillion requested enhancements. Only one has priority, we currently use nightmare code to parse trackwork details. Let me explain. The trackwork manager has an Android pad (I will not support any other product!) At the moment all they can do is email in the mornings trackwork data. It has to be in a specific format and THEY have to make sure it is formatted correctly.

If I try 'Form.Function()', I get 'unknown Symbol' error I know I can use the disk for passing something backwards, but I would first ask if there is a way. Karl, I don't know whether this will help in your case but there is a way to do this ... for examples where the component class is inherited by an application class. Due to the virtual dispatch used by gambas, the actual method called will be the inherited method. So (for general readers) if you consider a component containing a base class Fred that is inherited by a class in the main application, say SonOfFred, then when some local call in Fred, for example Fred.Describe, if this method is also provided in SonOfFred then the actual method, SonOfFred.Describe is invoked. But in this case, there is a trick needed in gambas 3. You need to provide a stub method in the base class, to stop the IDE/compiler complaining. Let me expand. If SonOfFred has a method Decode that you wish to be able to be called (or in fact, invoked by the base class in some way,) then you need to create a stub method in Fred. I see this as the base class defining a method that must be overridden, IOW a sort of virtual method. Mainly I implement the stub to raise an error if it is invoked, i.e. in Fred we have: Public Sub Decode() Error.Raise(Decode not overridden correctly) End In your case though (assuming that by Form you mean the native gambas Form class), this will not work. The only quick answer I can think of is to use an event in the component that is going to (hopefully) be handled adequately in the application. Bit of a lottery though.

When Screen_Draw triggers I need to know if there are pending UDP packets so I can avoid rendering the frame until those pending network events are processed. The logic would look something like this: Public Sub Screen_Draw() If [there is data in the socket] Then Return [render a complete frame] End Basically I need to give processing incoming UDP packets priority over rendering frames since processing the packets is quick but rendering a frame is slow. I only want it to render a frame when there are no incoming UDP packets needing attention. I've been thinking about logical ways to do this, but if there is some inherent GAMBAS way that would be more elegant. Could you use some global counter to achieve this? For every UDP packet received, inc the counter and dec it on UDP_Read (or zero it?) Then Screen_Draw need only check that the counter is zero. I don't really know whether this will work for you but from your description it does sound like a classic semaphore problem. ??? hth Bruce -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

[Gambas-user] Expander control - two questions
Hi folks, 1) Is it possible to change the height of the header of the expander, i.e. the bit that remains visible when it is collapsed? At the moment, it is too high for one line and too short for two. 2) Is it possible to change the height of the expanded view depending on the size of its' contents, when the contents are a view control? I would like to use the expander as a fancy combo box, with a tableview inside it, listing selections in some detail and when a selection is made, then showing a summary of the selected row in the tableview. I have attached a mock-up of what I am trying to do. regards Bruce formpagelayout-0.0.1.tar.gz Description: application/compressed-tar -- Virtualization Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

Thanks abbat, The answers to many of you questions are in the gambas help files. You could perhaps avail yourself of these before posting such basic questions. The first thing I would suggest is to try and stop thinking in terms of VB.NET! Gambas is not VB.NET nor is it a clone of VB.NET, please try and think in gambas terms and not in VB.NET terms. I say this because a) we have all gone through the learning curve for gambas, again it's all in the help files, and b) some of us can get a bit upset by the constant reference to this works in VB.NET, why not in gambas questions. I will say one more thing, the gambas help files are very correct and they are also VERY SUCCINCT. In other words, you need to read every word on a help page and grasp its' meaning. For example, if I look up the Now keyword in the language index I see that it says that dTime = Now [ ( ) ] AS Date and it Returns the current date and time. On that page there is also a link to the Date Time Functions. On that page I don't see anything that obviously solves your problem, BUT! at the end of the page is a link to Intrinsic Functions and behold, on that page is a link to Format$ which by it's description ... Format a number or a date. looks like exactly the the thing you are after. Please don't take this the wrong way. I just think you need to spend more time reading the help pages (as we all have done). cheers Bruce -- Keep Your Developer Skills Current with LearnDevNow!

[Gambas-user] Re Issue 169 - a few comments
Hi emil.len...@gmail.com I have some thoughts on this. Static Public Const c As Integer Any (public) const could be defineable as being static by nature (all instances share the same value). The Static keyword for Const is not required and is not in the systax defined in the help for Constant Declaration. So a Static Const is the same as a nonstatic const. If anything the compiler should complain about the word Static being included in a Const declaration. Static Public v As Integer I don't see any reason why a dynamic reference to a static variable should not be allowed. It's just referencing the class level instance of the variable. From the help on Variable Declaration we get If the STATIC keyword is specified, the same variable will be shared with every object of this class. The Static keyword implies that there will be only one instance of that variable accessable by all instances of the class. There is no restriction of access being limited. Static Public Sub f() Now, here is where Static means something different to the above! Static when applied to a method infers that it can only access the static variables of the class. In fact it has a larger meaning in that it acts only on the class level instance (i.e. the instance created when the class is loaded). The reason for the restriction of access referencing to only via the class reference is less clear. I cannot think of an example at present (sitting in an airport internet cafe) but suffice to say that the meaning of the Static keyword here differs from the above. Static Property p As Integer This is similar to the above. A property really is one or two accessor methods. In that light, they are the same as the f method above. regards Bruce -- Write once.

[Gambas-user] Hopefully, an optimisation for gb.db.postgresql
Hi Benoit,
I was tracing through the postgresql library trying to figure out why
some tables would add, update or delete single rows in milliseconds and
others took seconds.
I found that the table_init function in gb.db.postgresql Main.c is
calling the field_info function for each and every column in the table.
Which in turn is querying the database catalogue for each column.
Thus in a table with a large number of columns, calls to .Create
and .Edit in gambas were taking close on half a second each (with a test
table of 46 columns and the database on another server).
With my LIMITED C knowledge I have hacked the table_init queries so that
the required catalogue columns are returned in the intial query and
moved what I hope is the relevant code from field_info into
table_init.
My limited testing shows that .Create and .Edit call timings have now
dropped to the order of .02 seconds, and the overall add, update and
delete times drop to around .05 seconds. That is an order of 10 times
faster.
Would you please take a look at the code for table_init below and see if
it makes sense to go this way. (The code copies and pastes OK into an
editor like geany, even though the mail may wrap lines ... so I hope you
can read it OK).

In one of the tabs, there is a GridView. This GridView shall expand with all the others. All this has been running well, although I did not set the controls' Expand-properties to True. Instead it was enough to set the HSplit-Expand to True, the rest didn't matter. First question: why does it run like this? Why doesn't it need Expand to be set in all controls which shall expand or at least for all containers? Now, for some reason I had the idea to set another container/control pair over the GridView. If I do so, it is automatically expanded. This is a bit tricky now, because this pair should not expand but keep a fixed size. How do I tell not to expand this container or control? Do you understand what I mean? Regards Rolf I think you need to look at what the various container Arrange properties are (or at least tell us). The Expand property should be read as can_Expand rather than will_Expand and depends on the Arrangement property of it's parent container. In other words, controls can't Expand by themselves. Nor does Expand in a container control what happens to its children, it just controls whether the container itself can Expand. Also note that the HSplit doesn't have an Arrangement property because it is intrinsically set to Fill. As it wouldn't make sense otherwise. hth Bruce -- Learn Windows Azure Live!

I have 5 production systems in gambas 2 that are represented by over 80 gambas projects. They each use one of three gb2 components to do database access. These 3 libraries are very similar functionally, they implement the Create, Read, Update and Delete actions on the database and some other utility functions (like checking if a row exists for a primary key value). In moving these to gambas3, I am trying to merge the three gb2 components into a single gb3 library. This has been 99% successful, everything but the Read functions have been rationalised, merged and now all these functions work using common function calls. Read is the problem, one gb2 component's Read function uses an array of primary key values, one uses a pseudo query string and one uses a class that represents a query by example structure. There are hundreds, possibly thousands, of calls to the Read function spread throughout all these gb2 projects. The signatures look like this: Public Function DBRead(oTarget as Object, vPKey as Variant[]) as Boolean Public Function DBRead(oTarget as Object,sQuery as String, Optional sSort as String) as Boolean Public Function DBRead(oQBE as QBE) as Boolean where oTarget is the object that the data will be loaded into. The functionality of the three Reads is the same - the rows read from the database end up in the target object. The only differences are the calling signature and how the target is specified (in the QBE example it is inside the oQBE class). So, here's my desire: Rather then go through all the projects and fix all of the calls to a common signature, I thought I could make a wrapper function in the new library: Public Function DBRead(...) as Boolean that would look at the Params and call an appropriate internal function to handle each type. I think that would be a lot quicker. As usual, I have complicated the problem by putting the wrapper function in a class that inherits the base DBAccess class. The reason being that at some time in the future, the calls will all be rationalised to a single signature. For instance, I'll possibly retire the QBE method as it is overly complex. The pseudo code for the public DBRead now looks like this: Public Function DBRead(...) as Boolean Dim localtarget as Object Dim localquery as String Dim localsort as String If Param.Count = 1 and Param[0] is QBE then decipher_QBE(Param[0],localtarget,localquery,localsort) Return Super.DBRead(localobject,localquery,localsort) else Return Super.DBRead(Param.All) Endif The base class DBRead(...) theortically can decipher which call type it's got OK. BUT~! I can't debug it??? When I try and display the Param class in the debugger or include things like Debug Param[0] it shows an Out Of Bounds error.

You made a big mistake by making your controls inherit UserContainer, whereas they are not containers. Which makes the IDE mad when you want to use _DrawWith or some other properties. Yes, that makes sense. They must inherit UserControl. I used UserContainer in gb2 for some reason lost in the mists of time, I think it was to do with a handy property in the UserContainer that was not in UserControl. I thought that maybe the reason has gone away now so I retried the LabelTextBox inheriting UserControl. However, I have struck a problem - I can't seem to restrict the Height value if my control is used inside a container that enforces it's own height. For example, if the LabelTextBox is inside a HBox it's height will expand to the HBox height. I realise that this is what is supposed to happen but it's not what I want to happen. I have attached two screen shots showing my problem. well it's not a problem from gambas :) you must add more containers to achieve what you want to do : HBox |__ VBox(expanded) | |__ hBox | | |__ Label | | |__ SpecialTexBox(expanded) | |__ Panel(expanded) |__ Picture this is how gambas containers works :-) Yes, I know! and this is what I am trying to subvert. I see what you are saying about the expandable panel. In fact the custom control includes the hBox, Label and TextBox. So the (failing) model is: HBox |___LabelTextBox |___Picture The desire is to constrain the height of the LabelTextBox so no matter what the custom control parent's Arrangement is, the LabelTextBox.Height is immutable. That is the requirement, pure and simple. I don't know why my intentions work when inheriting UserContainer and not when inheriting UserControl. I'll look into this further this week to see if I can characterise it properly. your widget are usercontrol ... not containers ... that have no need to work like a panel or anything on this ype Funny thing is, the requirement is met when LabelTextBox inherits from UserContainer, but not when it inherits from UserControl. This is what I am trying to understand. Or maybe I didn't understand what you want to achieve at all! The intent is to give my two volunteer designers/coders with simplified controls that: - behave in terms of navigation the same way in both QT4 and GTK+ that is the work of benoit and gambas Not in this case! :-) I want it to work my way not the gambas way! In other discussions with Benoît, we have come to an understanding that some of the ways that GTK+ and QT4 work are mutually exclusive as far as Gambas is concerned, this is not a problem for me. I am working with a captive set of users on a thoroughbred training management system and the way that form navigation will work for this is around 90% my problem and not Benoît's. - provide some extra properties (e.g. the label) that can be set in the IDE and thus reduce both design and coding time you have just to export it and setup the _properties constant Yep, that's what I'm doing. - subsume the various native events (Activate, Click, Change etc) into a single Changed event that is only raised when the user has finished altering the value content of the controls ok - ( and at stage two), to build some data aware controls - like gb.db.form - but which will work with some standardised business object classes. ??? don't understand( that is already what gb.db.form do ... no ?) Yes, it does for the native database objects (basically Result) but what I am talking about are my own classes that provide much more extended functionality than the simple table oriented native classes. For example, a horse may be entered into one or several events in a trials meeting for some reason such as to check its' barrier manners, I have a business class for its' behaviour over the whole day. The database tables involved are horse, meeting, event, performance. These are all combined into a single object that will have the horse detail, the meeting detail and a collection of event+performance details. These are not simple table/row relationships but the whole view of the horse's attitude on a particular day. So the form using these objects will have say a bunch of textboxes and say a gridview. These controls will take their values from an object of that class expressed in the same way that gb.db.form does, i.e instead of a DataSource container there will be a DataObject container that uses the class object instead of a native db object. Is that clearer? I have done this in gb2 and it works well. But the code is extremely messy and I would not care to share it with anyone

[Gambas-user] User timezone - could I ask a favour?
Hi all, According to my web research the module below is the best way to obtain the user's timezone name (or Olson name if you prefer). This is because distros implement timezoning in different ways. It works fine for me using using the test harnesses I can devise for my (non-standard) distro. I was hoping that some of you would run it on your distro and report that it works OK. It should just print your timezone name like Arctic/Longyearbyen Thanks in advance.

[Gambas-user] Does gambas3 have the guts to make it?
Well you may have noticed a little drop off in my bug reports lately. I have just finished a little ETL exercise of a reasonable sized database (7.5million rows over 28 tables, heavily foreign-keyed, postgresql 8.3 backends on both sides). It took me a few days longer than I thought it would because I tried some major linux ETL tools first. Of the three I tried, al were java based, two were free and open source and one was commercial licence linux (30day non-crippled trial). One could not cope with any datatype stronger than an integer and insisted that all floating point numeric types have a scale of 1245678? (Guess which one). Of the two free ones, one just gave up and pointed it toes toward the sky on the first occurrence of more than 1000 rows in the transform set, the other is still going on a test machine (6 days now?). So. I gave up. And did it myself. I would have done it in gb2 but I thought I'd just see how gb3 went. The job took 6 projects, 4 to build nice clean base tables (including one of 1.1M rows) and two to clean, transform, recode and load the dependent tables. If we excuse the mistakes that I made in the DDL for the new database, which meant two re-runs, the whole development time was 14 hours and the elapsed time for the final run was 3hours and 12minutes. Nett result, 7.43million rows in new database in 16 tables. (How can 5 users create 70,000 junk records in a year? ) I have now run the 60 odd test queries to prove the data is correct (26 hours) with zero errors. So Benoît, I reckon gb3 definitely has got what it takes! :-) :-) :-) Thanks a million, or in fact thanks 7.4million! regards Bruce p.s.

[Gambas-user] gb3 database error handling
Hi Benoît, I don't raise these as bugs because they are only annoyances and don't (specifically) stop things from working. I have this code (which works fine when things are fine) but has a few quirks when a database error occurs. I made a simple test that just calls this and tries to add the same record to the database twice. Public Function AddDB() As Boolean Dim rwcursor As Result DBMod.Conn.Begin ' DBMod.Conn is just the current open database connection rwcursor = DBMod.Conn.Create($tname) Marshall(rwcursor, $colmap) ' This just moves the current values into the cursor Try rwcursor.Update If Error Then Debug db.Error, Error.code, Error.Text, IsNull(Error.Backtrace) Print Subst(1\n[phDB9_gb3: Base persistor database error (2)] 3\n4\n1\n\n, String$(60, =), Error.Code, Error.Text, Error.Where) DBMod.Conn.Rollback Return False Endif DBMod.Conn.Commit Return True Catch Print Subst(1\n[phDB9_gb3: Base persistor general error trap (2)] 3\n4, String$(60, =), Error.Code, Error.Text, Error.Backtrace.Join(\n)) End As I said, when the insert works all is fine, but on the duplicate key insert, I get the following output from the two trace lines in the If Error block Persistor.AddDB.404: 0 -1 Cannot create record: Duplicate entry '' for key 'PRIMARY' True [phDB9_gb3: Base persistor database error (-1)] Cannot create record: Duplicate entry '' for key 'PRIMARY' Persistor.AddDB.402 In the first line we see that db.Error=0 instead of the driver error code, I would have expected 1022 (mysql error: Error: 1022 SQLSTATE: 23000 (ER_DUP_KEY) Message: Can't write; duplicate key in table '%s'). Secondly, and this is more of an issue, the Error.Backtrace is null (as evidenced by True at the end of the line). So I can't get a full backtrace to the caller that is trying the duplicate insert. Thirdly, the gambas error code is -1? I thought that code was for errors raised within the project i.e. Error.Raise(Message) I have used that code (-1) to discern local vs system errors previously, is this no longer safe? Finally, the error message itself seems to be not populated properly, Duplicate entry '' for key.. In my test case the key is multicolumn, so this may be the reason. However, Cannot create record: Duplicate key for 'actual key name' on table 'table name' would (IMO) be a better message. regards Bruce -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

I feel your pain but it has sparked my interest following both your and Demosthenes Koptsis posts. I think that there are a few issues here that I may be able to offer some helpful comments on. Firstly, I don't know if you know, but there are a couple of things that you should know. These are the Linux Standards Base (also known as LSB) and the File System Heirarchy (also known as FSH). The latter, which is incorporated in the LSB, defines where and how things should be installed in linux so that other things2 know where to find them. One of the important things2 in this case is the GNU toolchain. That is, the C(++) compiler and linker, etc (etc being a whole bunch of other tools that are used to make creating a program executable simple and straightforward) so that all developers everywhere can reasonably expect to be able to provide a source tarball (or svn or git or whatever) that will compile and link regardless of the target environment. (Sadly, after the kernel.org hack much of this documentation is not readily available at the moment. But when it is back I encourage you to find it, get a good red wine and relax and browse through it. It is very enlightening and very well thought out.) Secondly, and this is probably emotive but here goes anyway, most responsible distros adhere to the LSB to a very high degree. There is one though that follows the be reasonable, do it my way* approach. (* my way being the one I** decide today) (** I being any one of a multitude of undisciplined code whackers) I won't name it, but let's just say that it might just rhyme with voodoo. According to the LSB (and the FSH) developers ought to expect that all linkable libraries (static or dynamic) should reside in /lib or /usr/lib. Nowhere else, not in /usr/lib/fred, nor /usr/lib/fredx64, nor /usr/lib/fred_x_6pence_and_a_farthing. (There is a caveat here, which is that the linker will allow you to override a library location specifically during a single run by using special arguments. This is so that the library developer can link in experimental versions of a library while they are testing it. This not meant for people trying to link to published stable versions of the library.) Now. (FANFARE!) There is a generally perceived problem with the current hardware mix of 32bit and 64bit architectures. I won't go in to them here beyond saying there is at least 2 wasted blogger-years out there on the internet and to say that it is perceived because it only exists in the mind of the media. It doesn't matter if the machine architecture is 64 bit, 32 bit, 127bit or 6.02 times 10^23 bit, the library that is compiled for the architecture should reside in /lib or /usr/lib. (For dog's sake, even Windows went through this argument somewhere back in the 14th century when they introduced .. can't remember .. something that jammed a 16bit call into a 12bit stack .. or something entirely useless like that anyway.) The point is, linkable libraries should be in /lib or /usr/lib. Or at least referable in /lib or /usr/lib ... Which brings me to links, symbolic or hard. (I am going to presume that you know about these things, what they are and why they work.) The reason I proposed to Demosthenes that he create the links between /usr/lib and whatever the strange directory his libfree files resided in was that it gets around the problem neatly and succinctly. In fact it is a commonly used method to allow linking (toolchain linker linking) to a specific version of a library. If you look at /usr/lib you will find many examples of this, such as /usr/lib/psylocibin.so is actually a symbolic link to /usr/lib/psylocybin-a.3.6417.so (or whatever, if you've followed me so far you'll know what I mean). Similarly, the links to psylocibin.la and other things follow the same pattern. Now here is the bit that I don't understand. libfreetype has been around since the dinosaurs started feeling a bit chilly. It's about as stable as granite. I have diffed the latest version, all the files (.la .a and .so and the source) they are all the same, no matter whether they are the 32 bit version or the 64 bit version. So why some

I was afraid of that. I'll do some research. I know it is possible in postgresql and I think it can be made generic across all inserts. As much as I hate delving in to the twisted entrails of mysql documentation I will endeavour... I don't have much expertise with firebird but there is a learning opportunity, I suppose. With sqlite, a quick look seems there is some probability. I doubt that it is possible with ODBC. I'll get back to you. Bruce Firebird being not GPL, it has been removed from Gambas. So don't worry with it. But I'd like to have the information for the others! Research results so far: 1) I expanded the frame of my original quest to see whether it is possible to implement a with re-read option for both INSERT and UPDATE queries. This would allow an automatic synchronisation of the gambas result with the true database row when the row has been updated with serial, default or computed values at the database level. The theory being that it would work regardless of whether the primary key columns were affected or not. Given the beaut way gambas works with updateable results, I think that the optimal approach would be to have an optional boolean parameter in Result.Update (i.e. Result.Update([WithReread=FALSE]) that would provide the feature but not break existing code. Alas, my C skills are not up to a point where I can try this out on my local trunk copy! Any guidance here would be appreciated. 2) Assuming the above, the internal workings of Result.Update would vary according to the dbms. Sometimes, returning the updated result is available directly from the dbms, other times it would have to be simulated via a subsequent SELECT. Further notes below. 2.1) The problem breaks down into two cases a) where the primary key columns are all provided (by the calling program) in the Result, and b) where some or all of the primary key fields are serial,default or computed. In the first case the solution is trivial, the subsequent SELECT has all it needs to query the updated row and thus refresh the Result object. The second case is more complex. However I believe it can be accomplished depending on the dbms. 2.2) For postgresql (since 8.x) the solution apears trivial as postgresql provides INSERT ... RETURNING and UPDATE ... RETURNING i.e. it can return some or all of the columns after the insert or update has completed. Further, this appears to be well protected from any concurrency or other side effects. 2.3) For MySQL (since ?.?) there is possibly a solution as there is a protected SELECT LAST_INSERT_ID(); that will return the last autoincrement for the most recently executed INSERT on a table containing an autoincrement column. By protected, I mean that it works on a per connection basis, thus avoiding concurrency side effects. Now since MySQL will only allow one autoincrement column per table, if the column is in the primary key then the above approach will work using a subsequent select on the resultant fully populated key. HOWEVER, there is still an unresolved issue if the db supplied key columns are not an autoincrement, say the key contains a db generated timestamp column. I am still looking into this. 2.4) For Sqlite the situation is similar to MySQL but simpler in some ways. It provides SELECT last_insert_rowid() to retrieve serial pkeys. I'm still looking at this as a) I'm not sure yet how far Sqlite goes in terms of the other computed column value types and b) it appears from some web pages that the version of this function in Sqlite2 has some bugs that may never have been fixed. 2.5) For ODBC, I have doubts. I'd have fewer doubts if I could actually get an ODBC driver to work at all on this machine. 2.6) Interestingly, Firebird (since 2.0) does support INSERT ... RETURNING and UPDATE ... RETURNING. Research contnues, but I'd appreciate any thoughts.

Or something like that. So that we can deal with many SQL requests at the same time easily. OK, but I have more a need to browse related table data. No big problem for postgres with pgadmin3, but the gambas2 database manager was more handy than the mysql and sqlite utilities.

[Gambas-user] Surrogate keys and database insertions
(This drove me bananas in gambas2.) Is there now (in gambas 3) a way to get the key of the row just inserted into the database when the key is a surrogate key e.g. a SQLite serial? For example, in the following, the items table has a surrogate key called id which is a simple serial. Private Sub CreateItem(item As Todoitem) Dim hRslt As Result hRslt = hConn.Create(items) If hRslt.Available Then Marshall(item, hRslt) 'Moves the item data into the result fields hRslt.Update 'So what's the value of the id field??? According to hRslt!id it is still blank. Endif End I've tried several ways to read the table and try to determine which row was just added, but there are too many problems like a) someone else may have inserted another row between the update and the re-read, so I cant just look at the highest id b) I or someone else may be inserting copies of an existing row, i.e. all the non-key fields now exist in more than one row. c) In postgresql, it is possible to create a pseudo query function that adds the new row and returns the key of it, but 1) this is postgresql specific 2) it means I have to use hConn.Exec instead of the nice simple gambas routines 3) it is messy code in the database and the function has to be created and maintained for each table Surely someone has come up with an answer to this?

i thought, i have to search for the first ' apostrophe from the left

nothing worked properly.
i used these lines to test:

of course, they should give

i got a solution that matched the first two ones correctly but no chance
for the regexp itself in line 3 (i always got something after the

First, because this is only evident in the runtime, I have a fear that testing the converted components may miss the error when the override is in a rarely executed area of code. Secondly, I can no longer override a method declared in a base class as Identifier(...) with a method in the child class with a real and restricted parameter set. To explain, I have a set of base classes in component X that provide the very fundamental features of an inheritance hierarchy. As well, they prescribe a set of methods that must be implemented in the child classes. In short, they are stubs for required methods. All they do is raise an error if the method is not overridden in the child class. Because of this, these stubs have no idea nor do they care what the parameters of the child class method are. As an example, I have a persistence model that involves three levels of code: the [application] uses--- [a business_object library] ---inherits--- [base_persistence] The persistence of the data is entirely handled by the two lower level libraries, the application only has to call the Create, Read, Update or Delete methods on the business_object object and all it's persistence needs are handled. The business_object library contains all the relevant business rules for its classes, e.g. whether objects can be deleted from the persistence or whether a cascaded delete is necessary etc etc. However, the business_object layer has no idea exactly how the persistence is achieved, it just validates the action applies the relevant transformations between the object data model and the persistence data model and then passes the object data off to the low level persistence methods in it's parent class. This is the high level design. The implementation employs the following code model: at the business_object library level, each business object has (at least) two classes, the main object class, e.g. Account and one or more mapping classes, say _sqlaccount and _xmlaccount. The main class is visible to the application, the mapping classes are hidden. The mapping classes provide the two way transformation between the object data and the persistence data, in short they have a Marshall method and an Unmarshall method. These two methods are very importantly visible to the base_persistence library. The last comment requires explanation. In the base_persistence library there is a similar split between the object model and the persistence model. There is a base BusinessObject class, from which all the classes in the business_object library inherit, and a base persistor from which all the mapping classes in the business_object library inherit. (There is a tricky bit here that is important to the design but irrelevant to this message - there is a base persistor for each persistance type, e.g. postgresql, mysql, xml, flatfile etc. Each of these is in separate libraries and is loaded explicitly at runtime by the BusinessObject class depending on the settings file for the business_object library. Suffice to say that it is the actual base persistor that provides the actual input/output methods to add, load, save and remove the data. Note the change from the CRUD method names!) When the application instantiates a business object, say an Account object called MyAccount, the constructor in the base_persistence library BusinessObject class i.e. BusinessObject._new() checks the persistence method in use and instantiates the relevant mapping class in the business_object library, i.e. it creates an actual persistor which is either a _sqlaccount or an _xmlaccount. How I do this is irrelevant, the important thing is that the BusinessObject has access to, via the gambas virtual dispatching feature, one of these things which as far as it is concerned is a persistor. The CRUD methods are actually public in the BusinessObject class, i.e. they are inherited by the classes in the business object library. So when the application does a MyAccount.Update, it is actually calling the BusinessObject.Update method. This in turn calls its' persistor.save method. In fact, what it does is call its' persistor.Marshall method and then its' persistor.save method. Note the subtle inference here, the Marshall method is the the one in the active mapping class and the save method is the one in the base persistor class (there is no save method in the mapping class). However, in order to compile the base_persistence libraries there must be a stub method called Marshall at this level and this is the one that MUST be overridden at the higher level. Further, at this level (in the base persistor libraries) I have no idea as to how the business_object library level Marshall method works, nor what parameters it needs to achieve

Now I will try to give you solution, but I'm not sure it is good as I'm not sure that I understood your description completely. So... 1) Not ensuring that the signatures of a child method is exactly the same as the parent method was a Gambas 2 bug that can lead to interpreter crashes. 2) In other words, as soon as a parent class A has a Marshall() method, a children class B that overrides Marshall() must use the same signature. The contrary is, for me, completely illogical. 3) If you want the children class to all have different Marshall() signatures, then Marshal() cannot be a member of the parent class. 4) So I suggest that you rename all Marshal() child methods into something like _Marshal(). And that you keep a Marshal(...) in the parent class that will call the _Marshal() method *dynamically* by using the Object.Call() method. Something like that: Public Sub Marshal(...) Dim aParam As New Variant[Param.Count] Dim I As Integer ' I realise that a Param.All property would be a good idea! For I = 0 To Param.Max aParam[I] = Param[I] Next Object.Call(Me, _Marshal, aParam) End Regards, -- Benoît Minisini Thanks, for looking at this (again) Benoît. I will build a simplified set of the structures and post it (it is just too big at 18 or so components to post as one chunk) over the next few days. I'll also have a look at your note 4 and see if that provides a way around the problem. But regarding note 1) Not ensuring that the signatures of a child method is exactly the same as the parent method was a Gambas 2 bug that can lead to interpreter crashes. This is the bit I don't understand. In the hundreds if not thousands of lines of code in my gambas2 projects, I have never seen it crash in this way. As I said these projects have been running for several years. And as to note 2) The contrary is, for me, completely illogical. I must disagree, method overriding is a well known object oriented design aspect.

[Gambas-user] Gambas3 control components _Arrangement incorrectly overridden
Another migration problem. I'm not having a good day. :-( I don't know if this is a bug or whether I'm just not looking at the code and/or the help correctly. I am migrating a bunch of specialised controls from gambas2 to gambas3. Much of it is working wonderfully but this one has got me beat. The attached project has two specialised controls, a trivial example called CBlueTextbox which works fine and one called ItemToolBar which doesn't. Testing the controls fails with the dreaded incorrectly overridden message, specifically UserControl._Arrangement is incorrectly overridden in class ItemToolBar. CBlueTextBox inherits directly from TextBox, whereas ItemToolbar inherits from UserControl. I realise that the _Arrangement constant for the textbox is meaningless. It's just there as an example. However I think it is needed in the ItemToolbar. (To make the attached project work, delete the ItemToolBar class.) regards and thanks in advance Bruce g3control-0.0.12.tar.gz Description: application/compressed-tar -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.

[Gambas-user] Gambas2 to gambas3 conversion - some problems
Hi Benoît and everyone, I have some misgivings about how gambas3 is converting or porting gambas2 projects. I'm talking about the way it is renaming the old project and creating a new project with the same name. This can have a result of breaking stable production gambas2 applications at worst and annoying one or more developers at least. From least to worst, the following scenarios arise: 1) the converter leaves the backup project (MyProject~) in a locked state. When the developer goes to open the backup project in gambas2 they receive the This project seems to be already opened message. Colin Confused, the developer, who has multiple instances of gambas2 running is annoyed because he has to make a decision as to whether it really is open somewhere (maybe even by another developer on another machine) or whether they should take the risk and open it anyway. I was going to raise a bug about this one, but some more thinking and testing led to the following. Analysis - annoying. 2) the converter ignores the existence of the .lock file in the gambas2 project and converts it anyway, thus if the project is open in gambas2 somewhere the following could occur. Steve Stable, the support programmer for gambas2 has MyProject open in gambas2 and has spent several hours finding and fixing an obscure issue and is just about to compile and test. Fanny Frantic, the new junior programmer, opens MyProject in gambas3 and says yes to the convert question. Gambas3 then renames (I presume) MyProject to MyProject~ and copies and converts the code. Steve Stable then presses F5 whereupon gambas2 crashes and all his work is lost (because the file system has been altered and his project now points to the wrong place). Analysis - could result in Steve causing serious physical harm to Fanny, therefore dangerous. 3) converting existing gambas2 components will break the gambas2 user projects that use them. Bruce Ballistic (senior programmer, head chef and dog washer) who is normally very careful to copy his gambas2 projects to a new gambas3 directory structure, accidentally opens the wrong project. He then makes major changes to the component and recompiles it. The existing (production) gambas2 applications will now fail as the symbolic links in .local/lib and .local/share point to the gambas3 component. Analysis - could result in Bruce muttering If I ever get my hands on that Minisini character, ..., therefore extremely dangerous. 4) I think (I haven't tested this) that there could be issues with .config/gambas as well??? In my opinion the converter should insist on the user entering a new name for the gambas3 project and leave the gambas2 structures alone, but at the very least it should be alerting the user in the strongest possible way as to which project it is going to convert and observe any existing .lock files. Please consider. regards Bruce where's my shotgun Ballistic Steve don't call me Stable, Fanny why are you hitting me Steve Frantic, and Colin ??

This is one the design rule of Gambas : a method has to always return

datatype, otherwise it must return a Variant.
Benoît,
I think you may have missed the point of my, albeit contrived, sample.
On the other hand I may not have made it explicit enough to let you
answer my fears. I'll try again:
Emil gave an example where the result a of a loop construct was one of
two closely related object references:
For i = 1 To 2
If i = 1 Then
a = New Class1
Else If i = 2 Then
a = New Class2
End If
Print a.F() + i 'Will print the address in memory for 2 + i the second time
Next
There is a hidden artefact in this code in that a (an object reference)
is of a particular inheritance sequence. However, because both Class1
and Class2 both have explicit and in the case of Class2 an overridding
implementation of an attribute called F the interpreter has optimised
that any a.F will be an integer, which is not true in the case where a
happens to be a Class2.
In resolving this issue you have spent a great deal of time and effort
on introducing a rule that says, to me at least, once F is declared
in Class1, then any specialised class of Class1 must declare F of the
same type,scope and signature as was declared in Class1. Please don't
react yet.
Just consider the replacement of the original code with this:
For i = 1 To infinty
Select case Int(Random(i:infinty))
Case 1
a = new Class1
Case 2
a = new Class2
Case 3
a = Object.New(gorilla)
Case 23165
a= Object.New(blue_whale)
Case 23166
a=Object.New(bowl_of_petunias)
Case 10^2134532 and falling
a=Object.New(trillian)
Case infinity-1
a=Object.New(marvin)
Case else
' I'll leave THAT for the readers homework
End Select
' Now magically and against all levels of improbability all of these classes
just happen to have a method
' called F. Strange, but not altogether improbable.
Print a.F() + i 'Will succeed, somehow in some format, or not
Next
the original code, at an improbability level of 2^3498423432 just
happened to include a situation where on the first invocation
Int(Random(i:infinty)) was 1 and even more strangely on the second
invocation Int(Random(i:infinty)) just happened to be 2. Many pundits
and philosophers have argued over exceedingly long lunches as to how
this came about, but at the end of the day disagreed. Which only gave
them the opportunity to have lunch again sometime, preferably before or
at the end of the Universe.
OK, enough of my reminiscing of Doug Anderson.
For i =1 to 2
a=something
PRINT a.F()
Next
Just because a happens to have a method called F, there should be no
RULE that a.F(), which happened to be an integer the first time is an
integer the second. It could be a small furry beast from Alpha
Centauri.
Emil's example, in my opinion, has sent you off on a search for an
explicit answer to the highly improbable sequence
Int(Random(i:infinty)={1,2} where Class1 and Class2 are related through
inheritance. His a is an object reference which just happens to have
a method F which returns an integer. Your optimization rule seems to
be any a.F() is an integer. I hope that through the above ramble, I
have illustrated that such a supposition cannot be considered to be true
in all instances.
Putting that another way, any expression that includes a reference to an
object cannot EXPECT that an instance within a (subsequent) iteration IS
going to return a SPECIFIC TYPE based on prior experience.
Benoit, I am Australian and therefore have a poor level of expressing
myself objectively and unemotively, in the English language.
Please Consider.
regards
Bruce

I don't see any way to store a completely arbitrary set of datatypes as a single structure property however. I could write them to a file, then read the file into a string and load it into a property of the array of structures, but that's just crazy. Kevin, I can't give you an answer to the question you ask, mainly because I kept seeing bigger problems as I read your post. From what I glean, this is a classic TX-ACK situation and I think you are basing the code on some type of timeout rule, such that TX-?-TX. However, there are some problems with that model. Firstly, where did the failure occur? a) firstly, the transaction was never sent from end A (why? is immaterial. What is, is that end B will not have any possibility of processing the transaction or sending the ACK) b) second, the transaction was fully received by end B, but for some reason it never ACK'ed it b1) it did process the full transaction, but never sent the ACK b2) it did not process the transaction and never sent the ACK c) the transaction was fully received, processed and the ACK sent, but it was never received by end A. Since at the end of the timeout, end A has no knowledge of the state of end B simply retransmitting the same transaction is considered bad design in network theory. (I could lookup the references for you, but they are on rotting pieces of paper somewhere in a mouldy box in the garage, and...) From memory, there are at least two well-formed models regarding these problems: i) any retransmission is marked as such. This puts a need on the server to audit any retransmission and either process it or ignore it. ii) any failed transmission is assumed to have been processed by end B and a reversal transaction is sent by end A before retrying the transaction. This means that end B must implement a reversal procedure, but puts the onus on end A to ensure that the transaction ONLY HAPPENS ONCE (not yelling, just emphasising). Disregarding your need to store the sent transaction for a moment, it might be wise of you to consider how these. hth Bruce -- Special Offer -- Download ArcSight Logger for FREE!
