Regards, Sven Hmm, but the compiler I'm using right now is a 2.4 and I think there is a leak if I don't call closethread. CloseThread was implemented for EndThread or how does it get called? I think the closethread has to be called outside the thread rather than inside the thread from what I tried, but I don't know. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] CloseThread needed? still unclear
While testing an updated version of nYume (aservia) I found that the program is leaking thread handles on Ms Windows. The program uses BeginThread and EndThread calls. However, when I add CloseThread() right before EndThread(, the program no longer leaks handles. So, CloseThread may be needed on Ms Win machines. I don't think (all) the docs state to call closethread. If CloseThread should be called on Ms windows, then this makes cross platform threading difficult since windows requires something different than unix. I don't know if the object oriented TThread uses CloseThread in it's backend code and don't know if TThread leaks, I was just trying beginthread and endthread style. To find handle leaks, I simply use Windows Task Manager to monitor the processes, with the Handles column visible. I am also trying some other tools like DrMemory. First I thought I would post this to the mailing list to ask you what the proper way to program with threads is. If we must call closethread on MS Win machines but not unix machines, then something needs to change to make the threading in the RTL more cross platform (and all the docs would need to mention things about closethread if it is needed). The compiler is 2.4.2 and 2.4.4 that i am using. The documentation is here: http://www.freepascal.org/docs-html/prog/progse44.html#x217-2310.2 But there is also more documentation elsewhere, such as the RTL docs. I guess I could look into Delphi to see how they use closethread. in their backend somewhere. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] ioda joda fulltext search not working

I got 1.2 working recently and had to edit the Config file and set fileref to 1 for it to work I think. So you have 1.3 working? whereas only 1.2 worked for me. Hrm. Meanwhile Darius Blaszijk and me created an own engine, which we hope to release soon. It will be used for the FPC docs (amongst other things). If you're interested and Darius agrees, I can send you a copy. It definitely works, I also use it in a commercial project to implement full-text-search on a firebird database. And it works with any FPC supported database as storage. Interested! L ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Now that would be pretty awesome! :) It is. When I showed it to the customers, they were very impressed :-) (considering their question was 'we want to do like google search but on the database') I was reading recently that MySQL has fulltext on InnoDB built in.. don't know much about it but I came across that recently while googling. Firebird has no fulltext built in to it I guess, eh? Also does the Ioda Joda have positions of your search words found? Or it just weighs the results and throws away any positions of the words. I.e. if the first instance of searchterm was found, does it record that position, or just throwaway position info? I was thinking of using it like google too, but having the positions of the search terms in the document would help to give a preview of the text like google. Or is there some other way joda does this? You could just parse the entire document without using Joda for that (separate utility) and use joda for the weighting only, but I wondered if joda had something built in to memorize where the search terms were located in the document. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] ioda joda fulltext search not working
Has anyone got Ioda 1.3 fulltext search project working? Every time I try version 1.3 it doesn't seem to find any words in a file that is indexed when I try a simple demo with it. The project IODA is here: http://sourceforge.net/projects/ioda/files/ I make some sample files as follows: words.txt: test the file.txt: This is a test file for joda to TEST. If the test works it should index these test words in this file. And then I run the command: joda -s myarchive words.txt file.txt And then I run a query: joda -q myarchive test It returns no results of the word test. Any ideas? I compiled Ioda 1.3 it only after making some minor modifications to fix his procedure:=procedure assignment code. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
