continued from the previous post:

@marxian:

cutetube2 is compiled in ARMEL ScratchBox with debug symbols and not stripped -
in debian/rules:
...
qmake "CONFIG+=debug"
...
# dh_strip

unfortunately package qyoutube does not provide debug symbols, so some backtrace information might be missing.

I have coredump as well, though I doubt it will provide more information, as by the time the segfault appears, the block in question (the QNetworkReply that gets deleted in QYouTube::StreamsRequestPrivate::getVideoWebPage() ) as already gone. Will provide it at request though.

Segfault should be fixed now in qyoutube 0.1.6.

If https://github.com/marxoft/qyoutube/...823733a2a1b7d8 is the commit that is supposed to fix the segfault, I am afraid there is still a possibility for it .

Imagine getVideoInfo() called twice in a row. On the first call member variable reply is NULL, so we are safe (https://github.com/marxoft/qyoutube/...quest.cpp#L174 doesn;t get called). On lines 180 and 181 a new reply is created and finished() signal is connected. at this point we have a valid pointer in reply member variable. Before the finished() signal is emitted, a second getVideoInfo() (or some of the other function which uses reply) call is issued (whoever is the one that calls it). Now, on line 174 the first reply will get deleted, leading to use-after-free and thus - a segfault.

I think you should either have a separate QNetworkReply* for each function that issues a request and fail the function if there is already a reply which is not finished for it, or remove reply member altogether and use qobject_cast(sender()); to have the needed QNetworkReply * for getting the result and calling deleteLater()

I'll cook a quick patch on github using the second approach and will request a merge.

EDIT: Maybe the best approach is to use QSignalMapper
EDIT2: https://github.com/marxoft/qyoutube/pull/1

Request is not intended to support parallel requests. It is supposed to act like a state machine, so once it enters Loading state, no further requests should be made (except internally, such as following a redirect) until the state changes again. The mistake is in leaving it to the application to police this (which is what cutetube2 does). So, as far as cutetube2 goes, there should be no possibility of a segfault using qyoutube 0.1.6, but if some other application were to make a further call to one of the request methods during the Loading state, there could be a problem. I prefer to fix this by enforcing the intended behaviour.

Ofc I am fine with whatever fix you may end up with, as long as there are no more segfaults.

In the meanwhile, YT changed its base.js, making the current decryption function extractor non-functional. here is a fix https://github.com/marxoft/qyoutube/pull/2

Here is a fix for non-working YT encrypted videos on N900, needs CSSU(testing or thumb):

http://46.249.74.23/libsoup/libsoup2...+0m5_armel.deb

Download the package to a directory of your choice.

One should manually install the needed libgnutls26 dependency before installing upgraded libsoup deb, make sure you have maemo extras enabled:

as root:
apt-get install libgnutls26

you'll also need libgpg-error0 from extras-devel:
enable extras-devel repo, update, close application manager and in terminal, as root:

apt-get install libgpg-error0

after that, as root:

dpkg -i $DOWNLOAD_DIR/libsoup2.4-1_2.30.2-1+squeeze1+0m5_armel.deb

if media-player is the player you use with cutetube2, a reboot is needed (or mafw-gst-renderer process restart) for the new library to take effect

Have you updated to the latest version of qyoutube (0.1.7)? The qyoutube library is used to retreive the video streams, so it's important to have the latest version installed to ensure that the video streams continue to work. The same also applies to the qdailymotion and qvimeo libraries.
