Not a solution sorry, but a suggestion (or maybe this is already implemented, I haven't used SqueakDBX). :) Maybe it would be useful to add a pool for the connections so they aren't so many at the same time.

[Pharo-project] Please help!! Error: There is no free space in this set!'

by Mariano Martinez Peck

I know this is a alraedy known issue: http://code.google.com/p/pharo/issues/detail?id=1628 I am trying to make SqueakDBX work in 1.1 and it doesn't work because of this. Each DBXConnection is registered in the WeakRegistry just to close the database connection in case they don't do it explicitly. This this, I have a: addObjectToGarbageCollect: anObject WeakRegistry default add: anObject. And in DBXConnetion >> connect, I call that method. Do you know how to solve the problem? I read the issue but I am uncertain what should I do nor if it is fixed. I think this bug is really important. Thanks Mariano

[Pharo-project] ProgressDisplay package updated to improve portability to Pharo

by Ralph Boland

I have released an update to ProgressDisplay package to SqueakSource. Changes are to improve portability to Pharo and should not affect Squeak 4.1 users. The changes fix a number of problems in Pharo but a few remain. The remaining problems affect examples only, not the ProgressDisplay code itself. The problems with examples are: 1) The package uses the Squeak 4.1 Generators class which is not in Pharo. This will cause a few examples to fail unless the Generators class is installed first. Hopefully, the Generators class will be included in a future release of Pharo so this problem will go away. 2) The examples for testing user interrupts fail because the code uses the InputSensor class which is not in Pharo. The user interrupt code doesn't work in Squeak 4.1. If catching user interrupts is turned on the interrupts are caught but not processed until the progress bar closes. :-( I don't know how to fix this problem in Squeak 4.1 so I am hoping someone will tell me how or fix it for me. Meanwhile, if someone wants to implement a working version for Pharo that would be great (or tell me what to do). Keep in mind that, if possible, I need a version that will work in both Pharo and Squeak. Regards, Ralph Boland

Just see the size of the configuration of ConfigurationOfSeaside28 that handles pharo, sqeuak and gemstone installs. I'm sure that Dale tried to add also support for Seaside 3.0 in the same Configuration but that were so much effort compared to just create a new ConfigurationOfSeaside30 that handles only the required mcz packages for 3.0 and forgets and don't care about the mcz packages for 2.8. I was about of doing the same for ConfigurationOfMagma. I considered create a new ConfigurationForMagma11r2 that handles only the packages for that release (that are not so distinct to the previous release as in the case of Seaside, but the scenario is the same). No way. That is not the solution. Not at a long term. So the metacello repositories idea (that was already discussed before) was a perfect solution. > > > > - preinstall/postinstall actions > > - registering with system services (menu, mail systems, sockets, > > startup/stop list) > > > > > that is platform specific.

The ConfigurationOfSeasideXX aren't created, maintained, debuged or cared by the Seaside core developers. And that is good. They concentrate in the Seaside code, and the Configuration maintainers (Dale) concentrate in the installation issue in the various platforms. Of course the maintainer coordinate with the upstream developers to solve platform specific problems, and of course nothing stops a core developer of a Software Package to maintain the ConfigurationOfTheirOwnPackage (as OSProcess' creator is doing) > > > - number of monticello packages composing the package you're > > installing > > > > > that's dependencies Yes but they are distinct for each Pharo release: - because maybe the Pharo release already includes some package previously required by the package (e.g Announcements being part of the core) - because the new Pharo release unloaded some package that previously was part of the core system (e.g. if it depends on Crypto and crypto isn't anymore part of the core image).

I don't understand this previous paragraph. What config files are you refering to, the Metacello configuration? If so they are in Read/Write repositories to all to modify. Also, they are by the license notice in the page, MIT, so there is no way someone can stop other to modify the Configuration for adapting it when a new Pharo release (or gemstone or squeak) is out. > > > To me a central repository is essential.

Yes, I know, the ConfigurationOfMagma does depends on other packages too: OSProcess, WriteBarrier. That is not a problem. The problem is the proliferation of pre/post doits and custom conditionals to handle the distinct combinatios of Pharo (or gemstone or squeak) releases and Software Package Releases > > I think that most of this software management tasks are solvable by a > description of "requires" and "provides".

And that is precisely the point. As time goes on, the number of this "conditional" will grow exponentially, lowering the quality of the Configuration and difficulting the maintenance of it. If all of this can be solved by simply copying the current configuration to a new repository on squeaksource when a new Pharo release is out, then better for all, mainly for the maintainer that is the one doing the hard work of maintaing the configuration. > All of these descriptions require and provide anything.

Also, if the ConfigurationOfMagma, for example, is copied to MetaRepoForPharo1.3 (when Pharo 1.3 is out) and it needs ConfigurationOfOSProcess then I copy also ConfigurationOfOSProcess from MetaRepoForPharo1.2 to MetaRepoForPharo1.3 and then all is working correctly again. > Removing the packages from the MetacelloRepository as Stephane > suggested would just make them platform dependent.

I don't get it. :) A final point, the idea is that the end users won't see how things are implemented. The tools will have to be modified to understand this MetacelloRepositories thing. Gofer, GoferProjectLoader and Metacello itself will need to add an indirection when accessing repositories so that they access the correct repository for the image they are running on. With this the user will do Gofer new universe; "Here Gofer points to the Pharo10, Pharo11, etc" package: 'ConfigurationOfMagma'; load; Or better yet: Gofer project load: 'Magma'. "using GoferProjectLoader modified to understand MetacelloRepositories" and when doing a: ConfigurationOfXXX project latestVersion the references to required ConfigurationOfXXX dependencies will need to be taken from the same repository where the ConfigurationOfXXX was got. This way the "Universe" analogy of self-contained group of packages known to work in a given release is fulfilled. Cheers -- Miguel CobÃ¡ http://miguel.leugim.com.mx

[Pharo-project] Code autocompletion on not really fast machines

Hi, I'm currently using Pharo 1.1 on a Pentium 3Ghz ~ 4 years old machine on Linux. I feel that code editing is slow, auto-completion can hang the GUI for 2-5 seconds, especially when there's undeclared variables (I usually set them using the dialogs when I accept the code).

Re: [Pharo-project] HTTP client library in Pharo?

by Andrei Stebakov

Hi Andreas I believe that the key is in (quoting): "The syntax for the header is: cookie = "Cookie:" cookie-version 1*((";" | ",") cookie-value) ... " That means when you want to send multiple cookies (cookie1 has name1 and value1, cookie2 has name2 and value2) you send: "Cookie: name1=value1; name2=value2" In your case you send two different headers: "Cookie: name1=value1" "Cookie: name2=value2" Maybe some servers may accept this, but the one I am working with chokes on it and skips all the "Cooke: " statements following the first one. If you take a look at the "Live HTTP headers" with FireFox, you'll see requests with cookies follow the "all-cookies-in-one-line" rule.

By copying the configuration files you make a snapshot of the project without the possibility to alter anything. The configuration file itself is modified by the software project the file is for. Probably the software project does not want anyone to write in the config file. To me a central repository is essential. It is a single well-known source and it carries the idea of cross-platformness :) Isn't that would you are trying to solve not just another ConfigurationOfXXX file. For the moment let's call it ConfigurationOfPharo10Universe. There you can refer to every single version in another ConfigurationOfXXX file that is said to be runnable in that platform. And you can decorate it with pre-/postDoits as you want. I think that most of this software management tasks are solvable by a description of "requires" and "provides". And metacello solves it well. As an example let's think of an example like ConfigurationOfPharoWebDeveloperImage (maintained by the image provider). The developer image develops linearly hence no version number in the file. The ConfigurationOfPharoWebDeveloperImage has dependencies to 20 other software projects that are all defined in a ConfigurationOfPharo11Universe (maintained by the community). Let's say it has a dependency on 'Seaside 3.0'. ConfigurationOfPharo11Universe offers 'Seaside 3.0' and has a dependency of 'Seaside 3.0.3' in ConfigurationOfSeaside30 (maintained by the seaside maintainers). ConfigurationOfSeaside30 has a dependency to 'Grease 1.0.3' in ConfigurationOfGrease. So let's asssume finally that ConfigurationOfGrease would have a dependency to 'Pharo 1.1' when run under pharo1.1 or to 'Pharo 1.1 compat package' when run under pharo 1.0 (metacello allows us to do that). All of these descriptions require and provide anything. And the descriptions are services offered from one group to another taking a certain responsibility. You can always rely on things like "Seaside 3.0" if you trust the people and if not than you use "Seaside 3.0.4rc2a". What I wanted to say is that there are plenty of situations where you want to cluster software packages together. By copying the files you just double to stuff without being able to tweak. Removing the packages from the MetacelloRepository as Stephane suggested would just make them platform dependent. Having less files and clear roles who might change them is something achievable IMHO.

Re: [Pharo-project] eCompletion tweak for smart characters

by Lukas Renggli

Hi Tim, I've integrated your changes. I chose a slightly simpler implementation and slightly different behavior (I think) that I interpreted from your code as "do not complete smart characters if there is no separator and not the begin or the end of the text to either side of the cursor". TextMate seems to do that too. Lukas On 3 August 2010 12:21, Lukas Renggli <renggli(a)gmail.com> wrote: > Hi Tim, > > Thank you for the contribution.

Instead I think there is a heuristic which says that says if you type a smart character with the cursor next to a non-whitespace item, you probably don't want the matching character. e.g. >> >> 5 max: 4 > 3 ifTrue: [] {cursor here} - and I click next to the 4 (or the 5) to put the bracket and I get 2, and I really only want one. >> >> My patch tries to address this. >> >> I also didn't see any test cases for this stuff (and possibly some could be written - should I try to do that too?). >> >> Tim > > -- > Lukas Renggli > www.lukas-renggli.ch > -- Lukas Renggli www.lukas-renggli.ch
