Re: [Pharo-users] Slow compilation on one of my Windows PCs
I tried commenting primFlush: fileID in StandardFileStream#flush on my desktop PC and the store benchmark's speed improved significantly. Original result on Windows 7: 11 per sec Result without flushing on Windows 7: 9 430 per sec Original result on Linux Mint 17: 26 590 per sec Result without flushing on Linux Mint 17: 34 879 per sec Mentioned Linux Mint is in VirtualBox on the same PC. Also loading of Roassal2 now takes 58 seconds insted of 386.

Jan With this: http://stackoverflow.com/questions/14290337/is-fwrite-faster-than-writefile-in-windows It seems this all comes down to calling FlushFileBuffers. You can check what would happen if we just disabling the explicit flushing (comment out self primFlush: fileID in StandardFileStream#flush) and run the benchmarks. (Of course, I don't know what side effects this have, *I* think WriteFile calls flush on its own, and of course *if* this solves the problem, we can not just disable call to flush in the image, but have to change the windows file plugin). Nicolai Hess wrote Yes, the vm primitives, like I already told some messages above. FilePrimitives ARE slow on windows. We may get better performance, if we disable windows file cache/buffering and use slightly different ways to do the CreateFile and WriteFile calls, and do the buffering on our own, but this is not easy. Luckily (?), this may be alread work if we use the std file api (?) A small dirty test: store bench latest vm - '22.098 per second' modified vm - '31,027 per second' (in the modified vm I replaced all file operation from sqWin32FilePrims.c with the code from sqFilePluginBasicPrims.c) The result may seem strange, because both implementation will actually use win32s CreateFile/WriteFile methods, but maybe the second one uses better caching/buffering. nicolai -- View this message in context: http://forum.world.st/Slow-compilation-on-one-of-my-Windows-PCs-tp4834668p4835032.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. -- View this message in context: http://forum.world.st/Slow-compilation-on-one-of-my-Windows-PCs-tp4834668p4835044.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
[Pharo-users] skipping whole class
Is it possible to skip whole class from testing? I could do self skip for individual methods, but the problems arise even in setUp so I would like to stop the whole class from being tested. Is that possbile? Thanks, Peter

One thing that I did that I am not sure of is, whether Referer and User-Agent should be - or just when absent, I chose the first one but I am not sure. How does it work with FileStreams when the requests come from different threads of the server? I mean, is FileStream thread safe? I guess that if I have multiple images I should have a file per image, otherwise I couldn't write to a single file. Everything goes through Announcer, but that does not seem to serialise access (but I might be wrong). It should technically be possible to add monitor on the receiving end. If you have multiple images, that you need to consolidate things yourself. I will add the payload logging somehow. Maybe writing to an SQLite db. Let us know how it goes.

Hi Joachim, First, thanks for the feedback. Second, since you are on a different platform, that might be a factor. Did you test your problem on Pharo itself ? Because there are already unit tests specifically for the case you describe: #testEmptyLastFieldUnquoted #testEmptyLastFieldQuoted These obviously pass for Pharo, do they pass for you ?

[Pharo-users] loading with gofer without network
Hi, I'm trying to load a package (mcz) from the package cache with Gofer. |gofer| gofer := Gofer new repository: MCCacheRepository uniqueInstance; repository: (MCSmalltalkhubRepository owner: 'Seaside' project: 'Grease11'); version: 'Grease-Core-JohanBrichau.94'; disableRepositoryErrors; load As you see, I gave 2 repositories (the first is local, the second one is remote) to Gofer. If you try to execute this code without the network, it will failed! It shouldn't because the mcz is in the package cache. I think it is a bad behavior of Gofer. It does not have to resolve references for ALL the repositories because, at the end, you only use one. I want to change this behavior to only get the first resolved reference (no need to iterate more). If not acceptable, I could only ignore repositories not reachable (disableRepositoryErrors does not work for this use case). Is it ok to change it?

Re: [Pharo-users] does anybody use the AST navigation?
Because we could remove it. I think we never enabled it because we could not use good key combinations… the idea was to use ctrl-arrow keys for it… I still think that AST based navigation is a very good idea, removing it now without having ever used it for real is not good. Marcus, would that make sense to: * extract the core of the AST navigation as an API onto the RB AST (the ability to go up, down, left and right in a RB AST, basically), i.e. trying to preserve that way a bit some of the patterns solved by the AST navigation... * and reduce whatever is linked with the GUI / text morph components ? Oh, looking at the code, the two aspects are implemented together, so it will be painfull to refactor. Looking a bit more at the code... I'm interested by the rationale for askForNodeSelectionFrom: Thierry Marcus the problem is that the idea is cool but if nobody spent time making it useful for real then we will never know if it is working for real. I think that finding the right operations that makes sense can be probably difficult. Now we did the same analysis that thierry. The tree operations like parten children sibbling should not be on class side of nodes navigation but in the AST itself. We can keep used code in the image but I do not really understand why? So we have working tools such as the dependencies browser that could help us that were out of the image and things that nobody ever used in. For me I would unload the code and find a student or somebody interested to improve for real. Stef

[Pharo-users] Seeking help to build an accordion widget for GUI of sQuick
Hello All :) I am a newbie in Pharo and have started to build my first application i.e. an offline text search application namely searchQuick. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. Currently, I have built the basic structure of the application using Morphs and have a lot to cover on the GUI part. sQ basically returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. I plan to build an accordion widget (https://jqueryui.com/accordion/) or something similiar to view the results. I seek help on the implementation of this part. Looking forward to a positive response.

You can check what would happen if we just disabling the explicit flushing (comment out self primFlush: fileID in StandardFileStream#flush) and run the benchmarks.

[Pharo-users] Phratch: Support for Spanish language in the interface
Hi, Some teachers are considering to make some field work with Phratch on learning physics by modelling simple real world phenomena (uniform accelerated movement, free fall etc). I downloaded it today and try to change the interface to Spanish, but I couldn't find the proper place to do it. Has Phratch support for a Spanish interface. If not, how difficult will be to provide this and how can we help? Cheers, Offray

Re: [Pharo-users] NeoCSVReader and an empty field at the very end of a file
But before you ask for help on the Pharo ML you should run the NeoCSV code on Pharo to validate that your assumption hold there. If not, it is a porting error/problem. And unit tests are *VERY IMPORTANT* to maintain our sanity across versions and/or platforms. Again, what you report as a potential problem isn't one, I think. Please test on Pharo itself.

I wuld use them if I had them, so this is not an accuse or anything. It's just a huge load of work to keep tests up to date when porting newer versions, so I just ignore tests when porting.

I found a bug in this old version that is somewhat special. It seems NeoCSV cannot handle the situation where the very last field is just empty AND if there is no trailing CRLF at the end of the file. Somethinng like this: SecondLastColumnValue;;EOF In that case, readField fails because it tries to do a readQuotedField or readUnquotedField, both of which try to read beyond EOF. So I changed readField to this: readField ^self atEnd In case the very last field of a file is empty, like '45;56;;' ifTrue: [''] ifFalse: [self peekQuote ifTrue: [self readQuotedField] ifFalse: [self readUnquotedField]] and all seems fine so far. Side note: My original file has a trailing CrLf but if I upload it via a browser to a Seaside Server, the Browser cuts off the trailing CrLf (I can see this in the Browser's Network debugging tools - both in IE and FF) - so it seems NeoCSV has to be ready for this situation.
