-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everybody,
If you follow Poppler's development, you may have noticed that support for multi-threaded rendering using Splash has been merged yesterday. Currently, this seems to imply, that we can render an arbitrary number of pages concurrently, but we have to wait for rendering to stop until doing anything else, e.g. searching the document. In the branch [1], I tried to implement this condition using QReadWriteLock instead of QMutex as the synchronization primitive. Any comments on this would be appreciated. If you feel comfortable with building Poppler using a Git snapshot, testing this would also be very helpful. (Remember to correct the paths given in "qpdfview-pdf-plugin.pro" which are currently set up for my system and to change LD_LIBRARY_PATH accordingly when running the built executables.) Another issue that needs to be decided: This change was merged into Poppler's master branch and hence will almost surely be part of Poppler 0.24, but there is the question of whether we should incorporate those changes into our next release even if that predates Poppler 0.24, so that e.g. qpdfview 0.4 will use the multi-threading when Poppler 0.24 is released. I already did something like this by having usage of Poppler 0.22's improved Page::search method in qpdfview's releases before 0.22 was released. And it seems to have worked well, but it is a much smaller changed than enabling multi-threading. One the other hand, this feature is very much sought after by a lot of people. What are your thoughts? Try to have this in trunk as soon as possible or be more cautious about integrating this? Best regards, Adam.
