Hi, I was browsing through the archives and I came through an email by Amir Hossein payberah:
http://lists.ximian.com/archives/public/evolution-hackers/2004- August/004129.html (You may need to do some weird things to extract it from that page.) The attached code, packed in a calendar.tar.bz2 is a clear infringement of work partially copyrighted by me and released under GNU LGPL. There is a function file "date.h" in the tarball. Compare that with the code I and Mohammad Toossi last released in 2002: http://www.farsiweb.info/jalali/jalali.c The first version of that code was developed by myself personally, and my bad coding style of the time (I'm not much better now) shows itself clearly. Let's compare them: 1) The names of the variables are identical. Even the same naming style is there. For example, in my function gregorian_to_jalali, I had used badly named variables "j_d", "j_m", and "j_y" at the same time with things called "jd", "jm", and "jy". The same naming magically happens for his "jalalyDays" function. This is not limited to those. Almost every variable is named the same and has basically the same function: "gd", "gm", "gy", "g_d", "g_m", "g_y", ""g_day_no", "j_day_no", "j_days_in_month", "g_days_in_month", etc. This very much looks like newbie students copying code and not paying enough attention to at least changing their variable names. 2) The code is exactly the same in several cases. This is a comparison: My gregorian_to_jalali function: gy = g_y-1600; gm = g_m-1; gd = g_d-1; g_day_no = 365*gy+(gy+3)/4-(gy+99)/100+(gy+399)/400; for (i=0;i<gm;++i) g_day_no += g_days_in_month[i]; if (gm>1 && ((gy%4==0 && gy%100!=0) || (gy%400==0))) /* leap and after Feb */ ++g_day_no; g_day_no += gd; Its gregorianDays function: gy = g_y - 1600; gm = g_m - 1; gd = g_d; g_day_no = 365 * gy + div (gy + 3, 4) - div (gy + 99, 100) + div(gy + 399, 400); for (i = 0; i < gm; ++i) g_day_no += g_days_in_month[i]; if (gm > 1 && ((gy % 4 == 0 && gy % 100 != 0) || (gy % 400 == 0))) /* leap and after Feb */ g_day_no++; g_day_no += gd; The only change is replacement of my "/" division by his "div" function. They have even kept my "leap and after Feb" comment intact. I would very much appreciate it if the message could be removed from the archives. Also, I would love to ask for special care be taken when new contributors not already known in the community send patches for alternate calendar support to this list or evolution-patches. They may be infringing a few other people's copyrights at the same time. I am specially worried about a second message, from a certain Ali Shameli: http://lists.ximian.com/archives/public/evolution-hackers/2005- February/005173.html The part that claims that "We wrote a lightweight library to use multi calendaring in systems like Evolution." is very possibly about the code posted to the website "libmcal.org", which appears to be almost the same stuff, with the same copyright problems. (See the file "src/date.c" in <http://libmcal.org/download/ver0.5/libmcal-0.5.tar.gz>.) Thank you very much, Roozbeh Pournader _______________________________________________ evolution-hackers maillist - [email protected] http://lists.ximian.com/mailman/listinfo/evolution-hackers
