Hello gnuradio fellows, I have an issue that appears in all gnuradio versions I used lately (I started with 3.3 and last week I updated to latest from git) and I thought I should post here before allocating the time to look into it by myself.
I'm modifying a gnuradio block that is connected from python to 6 file sources. Everything works fine as long as the files I'm using as source for data are relatively small (30MB). When the files become large I see that the data received in general_work() function is corrupted. It is not massively corrupted but enough to screw my work. Investigating the problem, I did a small test with having the 6 files filled with known patterns and printing an error in the general_work() if what is received is different. The result is that if I use files with sizes over 100MB I see 50-80 errors in total. Now, to unblock my work I did observe that if I insert some printing in general_work() I will not get the errors. Going further, inserting a boost delay of 100uS also solves the problem. some more data: 1. I know the new blocks should use work() instead of general_work() but is it still supposed to work as long as I call consume_each(), right? 2. I'm using core i7 2900K if that matters This error has haunted me for long time but now I finished my work and thinking to look for the error (is it scheduler, the way data is taken from the file sources, where it should be?) and maybe fix it.
