Hi Andrey,
Thanks for the answer, your snippet looks very similar to what I
have. Perhaps if I posted my code segment would be of help in helping
me figuring out where I'm wrong.
During parsing CPU usage reaches 97-100% which causes my GUI to
hang(I have about 500 000 opening and closing tags and half of the
enclosed items I need to process: save, in some cases insert spaces,
etc), especially awkward when I start parsing whilst still fetching
the data from network(sometimes hangs during pageStack.push() ), but
it's bad for up to 2-5 seconds nevertheless. I wouldn't mind if
parsing took 10 seconds if GUI was responsive. This is what I'm doing:
void SomeClass::someMethod() {
MyContainer* container = new MyContainer();
//reader has a handle to container, through which it
populates the container
MyXmlStreamReader* parser = new
MyXmlStreamReader(container);
QThread* parserThread = new QThread();
parser-moveToThread(parserThread);
connect(parser, SIGNAL(finished()), this, SLOT(onParsingFinished)
);
connect(parser, SIGNAL(finished()), parserThread, SLOT(quit()) );
connect(parser, SIGNAL(finished()), parser, SLOT(deleteLater())
);
connect(parserThread, SIGNAL(finished()), parserThread,
SLOT(deleteLater()) ); parserThread-start();
reply = networkMngr-get(QNetworkRequest(someUrl)); //both
pointers are class members connect(reply, SIGNAL(finished()),
this, SLOT(onAllDataRecieved()) ); //this starts the parser with
the data available at the time,
// when parser reaches the end of xml document it emits
itsfinished() signal
connect(reply, SIGNAL(readyRead()), this, SLOT(parseReadyData())
);
}
To run parser in parallel just to get results in the main thread it is better
to use QtConcurrent::run() + QFutureWatcher.

Thanks again

Hi list,
I have a rather large xml file to parse and it causes the UI to
freeze, I assingned the parser to a different thread, but it
doesn't help much. According to the Qt documentation
QThread::setPriority() doesn't work on Linux, is there some kind
of workaround that could be used?
Thanks

Hi, On Tuesday 27 May 2014 08:17:52 Christopher Lamb wrote: Hi all I am pleasantly surprised at the volume of traffic resulting from a thread that I innocently kicked of that the weekend. Thanks for the active and balanced discussion. I probably won't be able to take an active part in the IRC meeting this afternoon, as it is during the Swiss working day, so here is a summary of some key points from the thread so far. There is a strong wish to avoid fragmentation of channels: That implies that anything new should be instead of / integrated into / a refinement of an existing channel (e.g. TJC) We currently have the following meeting channels of some interest to developers, each with a different focus. 1) Together.Jolla.com (TJC): Q/A site mainly concerned on the phone + bugs and flames. So far no dedciated area for development issues. just plain and simple: https://together.jolla.com/questions/scope:all/sort:activity-desc/tags:app-development/page:1/ For people who are less familiar with qa style it is possible to create a separate top page on TJC in the forum style providing most frequent searches as static subjects. Some part of https://together.jolla.com/tags/ So, there can be smth. like Announcements, Releases, Bugs, Development etc. 2) Talk.Maemo.Org (TMO): A forum, strongly used by app developers and their users. Unlike other channels. this is Jolla independent. 3) This mailing list: used by developers to developers (both inside and outside Jolla). 4) IRC Chat. similar purpose to 3) above. 5) Other non-Sailfish-dedicated developer forums (StackOverflow, Qt Project etc.) We heard from both supporters of mailing lists and forums. The one side will probably never convince the other. I suspect that I am used too… and personally I prefer … are more important as anything else. mailing list on the base of qa forum on steroids: https://together.jolla.com/users/4/YOUR_ID/?sort=email_subscriptions Both tools have their plus points and weakness. Here are main ones.. Mailing lists (with the appropriate mail client) appeal to those who like the structure of tree views. There is a certain charm in the simplicity of mailing lists (KISS) which do not have all the extraneous functionality / bells and whistles / baggage / bullshit (you choose) that forum or QA sites do. Mailing lists do require a powerful properly configured mail client to be used properly. In a Forum you get that for free in a web client (but can't do much to customise it). Mailing lists aggregate communication in your mail client - avoiding the yet another thing I need to visit .. syndrome. Forums allow editing of previous posts to correct typos / make clarifications. Forums typically have extra functionality: e.g.like, formatting, stickies, the dreaded karma… Privacy: Some forums use avatars, and allow you to suppress your personal email. Forums support sub-forums. At the moment we are talking about splitting the list into development and other, but what happens when we want to split it further? (Jobs, C++, QML, Silica, OpenSource etc.). sub-forums: Devel-QML: https://together.jolla.com/questions/scope:all/sort:activity-desc/tags:app-development,qml/page:1/ Devel-Javascript: https://together.jolla.com/questions/scope:all/sort:activity-desc/tags:app-development,javascript/page:1/ etc. - denis Cheers Chris On 26.05.14 21:43, fasza2mob...@gmail.com wrote: Hi all, I think Norman is bang on with the fragmentation issue. To address this I propose a possible solution. Why not convert this mailing list to a 'virtual' one; By that I mean move all discussion to a devel section on TJC and have the mailing list be another frontend or interface if you like for the same content(yet better, keep all mails and posts with their metadata in the same database and create an API that both ML and TJC can call thus eases applification too, kind of like MVC). To accommodate this TJC (or at least the proposed devel section) would have to be changed/improved to have a treelike structure alongside its QA nature so that OT answers and its children can easily be tagged and filtered out in both TJC and ML interfaces. OT tag should be available for every poster to tag their answer/comment. To achieve this there should be 2 scripts one that converts each mail to mailing list to a new question/answer/comment retaining the treelike structure and one other sc ript that posts entries from TJC to ML setting the subject correctly as it is now; Perhaps with an x minutes latency to alllow for editing post. If one wants to use a different email address for the mailing list that is set for TJC a setting should be available. Further to this subsections(Qt, Qml, news, politics, ads, jobs etc) could be introduced making it easier to filter or subscribe to selected

Even if there is together.jolla.com, I haven't yet seen many concrete Sailfish development topics discussed there.
