Where's the final line of diffstat output, though? The above says that you mostly deleted a few lines from buf.c, but it does not tell how many and whether you also added/edited anything. Overall, it does show that you made very little progress. You should try not only to fix problems in code already written, but also make progress at further tasks each and every day. Maybe limit your fixing of existing code to 4 hours per day (this sounds excessive to me, but it works as an upper limit), and use the rest of time (4+ hours per day since you need to work hard during the remaining GSoC time) for writing new code. How does this sound to you? Alexander ^ permalink raw reply [flat|nested] 4+ messages in thread

Overall, it does show that you made very little progress. Hey, I just checked my e-mail. I removed ~ files, binaries, git data etc, which is why I thought the last line made little sense. > You should try not only to fix problems in code already written, but > also make progress at further tasks each and every day. Buggy code doesn't help much. That said, I did focus on pthread_eintr today, rather than alloc. I'm pretty stuck with alloc. I just can't get it to work with musl. Valgrind is clean, strace says little (or perhaps I just can't interpret it well), and gdb - it just won't follow the second child, so I can't step through it as I hoped to do. > Maybe limit > your fixing of existing code to 4 hours per day (this sounds excessive > to me, but it works as an upper limit), and use the rest of time > (4+ hours per day since you need to work hard during the remaining GSoC > time) for writing new code. How does this sound to you? The thing is, writing code means writing bugs, so it's just a matter of time when the fine line is crossed. However, I'll try to take on other tasks as well - esp. those that Rich suggested. Luka ^ permalink raw reply [flat|nested] 4+ messages in thread

Going forward, please remove those extra files before you run diff|diffstat. Don't edit diffstat output. If needed, you may make copies of the cluts tree and remove extra files from the copies only. > >You should try not only to fix problems in code already written, but > >also make progress at further tasks each and every day. > > Buggy code doesn't help much. True, but you can't afford to spend over 50% of the remaining GSoC time on fixing bugs and getting stuck on some of them. This would be OK if you already had everything implemented, but you don't. > That said, I did focus on pthread_eintr today, rather than alloc. OK. > I'm pretty stuck with alloc.

This may or may not be the best approach, but you may try inserting: asm("int3"); just in the child process or thread that you want interrupted. You may even make the int3 conditional in the code (check whatever condition you like with an if). Or at high level, you may set the same breakpoint from gdb itself.
