Re: [Pharo-users] CrossMorph in PBE and compositing bug

by Edward Povazan

Thanks. It does work to add a little alpha to the colour, but is there no other way? If I want a solid colour, then what? I should be able to say âthis is a weird shaped morph, not a rectangleâ, but not seeing it. -Ed > On Dec 26, 2014, at 11:58 AM, Hilaire <hilaire(a)drgeo.eu> wrote: > > Hello, > > Morph color can be set to translucent, in your example it is problably > set with ColorTranslucent r:g:b or a similar class.

Hello, Morph color can be set to translucent, in your example it is problably set with ColorTranslucent r:g:b or a similar class. Not sure about the name.

CrossMorph in PBE and compositing bug

by Edward Povazan

Hello, In the PBE example, and CrossMorph is created. As can be seen from its name, It is has a cross shape. When one adds keyboard handling to move it about, it seems the compositor thinks it is opaque, and doesnât repaint the ânot crossâ areas with whatever is behind the morph. The result is the shape smears across the screen. This only occurs when moving exactly horizontally or vertically. Iâve been looking over the Morph API but canât detect a method like #opaque: or #translucent: or similar. Is this a bug, or am I missing the correct way to deal with transparent/irregular shaped morphs? Thanks, -Ed

Re: [Pharo-users] Question regarding crashes using OpenDBXDriver

by Michael Berg

Hi everybody, thank you St-Jean, Stephane and Guillermo. Iâve been trying to get it working for the last two days. My last action today was to finally compile OpenDBX myself, as all the evidence seemed to suggest that somehow it must be a/the wrong version of whatever MySQL client lib I used (or MariaDB client). In the end I always got a crash after trying to disconnect. If I was lucky and everything was fresh I might have been able to query something, but somehow the image ârememberedâ that I did something to it, donât know (I mean even not by saving the image). Now with the current version of 1.4.6 of OpenDBX and the original MySQL connector/C version 6.1.5, with the current Moose 5.0 image (Pharo 3.0), I can connect, disconnect and query as it should be. But :(, if I did at least one connect/disconnect and then close the image (with or without saving), I get an âMicrosoft Visual C++ Runtime Libraryâ Runtime error, thus Pharo doesnât end correctly. So far I just tried to get some more information by attaching the Visual Studio debugger to the process and it seems that the last thing before the error is the libmysqlbackend-1.dll unloading. Depends-x86 shows no special missing dlls, just one marked red âc:\windows\system32\API-MS-WIN-CORE-SYNCH-L1-1-0.DLLâ and three others not being found. But at least the latter ones are normal and Pharo itself has these dependencies not being found. The red one concerns âSleepConditionVariableCSâ, but I have no clue whether this is in any way important or meaningful in this context. I just wonder if somebody of you guys has an idea now, as a crashing Pharo still has some bad taste to it. One further thing I donât understand: After the creation of one DBXConnection and a subsequent connect message the system has two instances of DBXConnection in the system (via DBXConnection allInstances). Is this ok? Why? I tried to step through all the creation code, but somehow didnât find or missed the creation of the second instance (probably somewhere in âplatform createConnectionâ). Also every time I get back into the image and connect/disconnect again I got two more instances. Shouldnât they get garbage collected? And last, but not least, even though this should probably belong into the Moose 5.0 thread, but Iâm not sure I miss something. In a fresh Moose 5 image I wasnât able to call code with fresh variables in the Playground, due to a class WorkspaceVariable missing. So I changed GLMMorphicPharoPlaygroundRenderer >>workspaceBindingsStrategy ^ [ :currentBindings :aString | (currentBindings includesKey: aString) ifFalse: [currentBindings add: (WorkspaceVariable key: aString asSymbol) ]. currentBindings associationAt: aString] back to GLMMorphicPharoPlaygroundRenderer >>workspaceBindingsStrategy ^ [ :currentBindings :aSymbol | (currentBindings includesKey: aSymbol) ifFalse: [currentBindings at: aSymbol put: nil]. currentBindings associationAt: aSymbol] Unfortunately I couldnât figure out if WorkspaceVariable was there when the change went into Monticello, thus had no idea where to get it from. Sorry for the long email. Thanks to everybody for the help, it encouraged me to keep trying to get it running. I didnât try the ODBC connection so far, as I guess this will prevent me from running Pharo potentially in the cloud (except Azure)!?

My first step was to try to get somehow a MySQL connection working. As it seems there arenât that many ways of using a MySQL database from Pharo, I tried to use the OpenDBXDriver. do you mean the MysqlDriver that is packaged in the DBXTalk project? My problem is that I get often VM crashes. It seems that if I use a completely fresh image I get at least to the point I can query the db. But after the image crashed the foreign process crashes already sometime after connecting to the db (about 30 seconds later, maybe some timeout) or right away upon trying to disconnect for example. I can just imagine that something was left behind after the first crash in the fresh image and after that I canât get further than that. I know this is a pretty fuzzy description, but due to NativeBoost being involved itâs quite hard for somebody quite unfamiliar with Pharo/Smalltalk to see where things might go wrong. At the end of the email I include two crash-dumps, so maybe somebody has an idea and can help. You know it would be an ffi call it would be the same. A foreign lib is a foreign lib. So which versions of the lib and others are you using? I also had to work around (fix would be the wrong word) a problem that when the DBX code tried to get the column names; after the first column somehow odbx_column_name from the C-Api returns NULL or NB creates a nil from that call, so that the following readString send fails. Again because this happens somehow at the C side of things I couldnât (or didnât know how to) look further in the debugger. Just to see if I can get a resultset at all I changed NBPharoOpenDBX>>apiQueryColumnName:index: to Fileout: 'From Pharo3.0 of 18 March 2013 [Latest update: #30862] on 18 December 2014 at 3:44:48.371881 pm'! !NBPharoOpenDBX methodsFor: 'api calls' stamp: 'MichaelBerg 12/18/2014 13:36'! apiQueryColumnName: handle index: index "char* odbx_column_name(odbx_result_t* result, unsigned long pos )" "IMPORTANT: Index es zero-based" | x | x := self openDBXlib odbx_column_name: handle pos: index. ^x isNil ifTrue: [ 'nil' ] ifFalse: [ x readString ].! ! That way I got at least a result and for some reason the similar method getting the column type just worked. Maybe somebody has an idea or has experienced similar things before. Any hint or help is highly appreciated. :) Thank you and cheers.

Re: [Pharo-users] [Pharo-dev] how do you use scripts?

Here are some questions to start from, but feel free to diverge: > For me there are two kind of environments that are imported. On the one hand there is the desktop with a GUI, something that I start manually and that is being saved regularly for me to stop and continue working. On the other hand it is a server environment where everything needs to be started automatically without any GUI. This environment is never saved and always started from the same saved state. > - What kind of actions do you put in scripts? > Setup, configuration and orchestration of components.

I have separate directories for all of my projects. So the project dependent workspace files are just in that project folder. I'd like the idea of organizing scripts but then accessing/navigating to them is more effort then to type it again. I also store scripts in text documents for e.g. having quick access to Gofer snippets in order to load common modules I use. This is mainly to set up the project before writing a metacello config. And not all of those components can be accessed via configuration browser. On the server I've built a utility that accesses a directory full of snippets in a Unix SysV style manner. As an example for our mobility server: root@2d-apis:/opt# ls -1 mobility-server/launch.d/ 10_restore-ui-manager 20_rfb-vnc-server 30_logging 40_mongodb 50_start-mobility 60_scheduler 95_server-setup The prefix number organizes the order of execution of the snippets. The snippets are a mixture of shared and individual scripts. Meaning scripts like restore ui manager and rfb-vnc-server are shared among all installations because they are always the same. I just symlink them into my projects launch.d. A script like rfb-vnc-server looks like this root@2d-apis:/opt# cat mobility-server/launch.d/20_rfb-vnc-server self optionAt: 'vncport' ifPresent: [:portString| RFBServer reset. rfb := RFBServer current. self optionAt: 'vncpassword' ifPresent: [:password| rfb setFullPassword: password ]. rfb start: portString asNumber. self log: 'RFB vnc server started on port ', portString ]. This way I can switch rfb on and off using a commandline switch that is added to a project configuration. This all is part of image-launcher I want to release for several years now :) If anyone is interested please ask. > - Do you version your scripts? Workspace scripts are versioned via timemachine backup only. Server side scripts are put into git. > > - Do you store them in separate files with dedicated names, or tend to put multiple snippets in one larger file? > On the desktop it is more the latter because everything a project depends is in one or two workspaces. On the server as you could see above everything is separated into indvidual scripts > - Do you rely on the names of the scripts? > On the server for tweaking the order of execution. > - Why do you use a script file and not a class? Some of the scripts I put into classes when they grow up to be an utility function. Parts that contain contextual information I don't put into classes because I don't want to have filesystem paths, ip addresses and such inside my code and they are too static if something changes. I think putting stuff in classes is not always an option. To me scripts act as glue between the image and outer world where to image have to live in. Scripts are flexible and adhoc. In my case there is a workflow where a jenkins server builds the deployable image. If the script code (e.g. for startup) in the image needs to be tweaked you need to change the image in order to fix it and there are workflows where this would be pain (rebuilding the image and deploy it to have the change in effect). So scripts in text files have superpowers here. Norbert
