| freemangordon | Pali: yes, it unlocked the motex | 00:01 |
|---|---|---|
| freemangordon | *mutex | 00:01 |
| * freemangordon is even more confused | 00:01 | |
| Pali | so it is as I was expecting... | 00:03 |
| freemangordon | seems like docs are not telling the whole truth :) | 00:03 |
| freemangordon | yes, exactly as you were expecting | 00:03 |
| freemangordon | but how is that possible? | 00:03 |
| freemangordon | to release a mutex held by thread A from thread B?!? | 00:03 |
| Pali | it is implemented by linux futexes? | 00:06 |
| Pali | or something else? | 00:06 |
| freemangordon | pthread_mutex_t | 00:06 |
| freemangordon | and this is cute http://stackoverflow.com/questions/5454746/pthread-mutex-lock-unlock-by-different-threads | 00:06 |
| freemangordon | "What you've done is simply not legal, and the behavior is undefined." | 00:07 |
| freemangordon | :D | 00:08 |
| *** sandstorm has quit IRC | 00:09 | |
| Pali | so it using futexes | 00:09 |
| freemangordon | ok, if you say so :) | 00:09 |
| freemangordon | so? | 00:09 |
| Pali | and I think you can unlock futex from another thread | 00:10 |
| Pali | as it is same (mmapped) memory | 00:10 |
| freemangordon | ok, my conclusion is that this is illegal and implementation specific | 00:10 |
| Pali | yes | 00:10 |
| freemangordon | we must rework it | 00:10 |
| freemangordon | but at least now I understand what happens | 00:11 |
| Pali | but on linux 2.6+ when futexes are used by default it is working | 00:11 |
| *** chritizn has joined #maemo | 00:11 | |
| freemangordon | I don;t believe this is the only way to make async function sync | 00:12 |
| Pali | never! do not do that | 00:12 |
| *** chritizn has quit IRC | 00:13 | |
| freemangordon | Pali: mind you, this is what we all have in our devices ;) | 00:13 |
| Pali | 3x I thought that I have working code (in qt) which creating blocking function from async callls | 00:13 |
| Pali | and after some time I found special case when it is not working | 00:14 |
| freemangordon | I'd rather start another thread and wait() on it | 00:14 |
| freemangordon | or something like that | 00:14 |
| freemangordon | qnyway, I'll find the proper way once I am on it | 00:14 |

| Oksana | A question: is GPS firmware of N900 closed-source? | 04:10 |
| jonwil | GPS on the N900 is handled by the cellular modem | 04:16 |
| jonwil | and the firmware for that is closed source | 04:16 |
| jonwil | On the userspace side its handled by a number of daemons and libraries, all of which are closed source | 04:16 |
| jonwil | Although I have recently figured out a good whack of how the userspace bits work internally through reverse engineering | 04:17 |
| Oksana | Thank you! | 04:18 |
