W minionym miesiącu: nowe translatory, poprawki błędów.
Tak, w tym miesiącu mamy drobne opóźnienie. Arne Babenhauserheide, który zainicjował sam projekt i tworzył pierwsze szkice wszystkich comiesięcznych wiadomości na temat Hurda od czerwca 2009 (tak, to już półtora roku!), zajął się innymi obowiązkami — jego żona urodziła pierwszego potomka dewelopera Hurda (wg naszej najlepszej wiedzy): – W zeszły piątek mój syn Leandro wkroczył do naszego zimnego i zbyt jasnego, acz przyjaznego świata, (…)
Życzymy im powodzenia w nowych obowiązkach rodzicielskich!
Thomas Schwinge, który dotychczas współtworzył i publikował wiadomości, przejmie ten obowiązek — przynajmniej tymczasowo (miej to na uwadze, Arne).
Ale mamy też jakieś informacje o Hurdzie, jak najbardziej.
Olaf Buddenhagen opublikował łatkę, która pozwala uzyskać liczbę portów proc i libps aby dodać nowy RPC — w wyniku czego zainicjował dyskusję z Samuelem Thibaultem, który złożył propozycję, aby zamiast dodawać tę funkcjonalność sformułowaną ad hoc, poszukać bardziej ogólniejszego rozwiązania. W końcu zgodzili się, że owa funkcjonalność jest wystarczająco przydatna i łatka została zatwierdzona.
Istotnym jest aby dobrze projektować interfejsy (w tym wypadku do RPC), jednak z drugiej strony to co obecnie tworzymy nie musi trwać wiecznie, co wyjaśnia Olaf Buddenhagen: – Cóż, już posiadamy mechanizm do tworzenia protokołów komunikacyjnych: nazywa się on RPC… 🙂 Postarajmy się nie wynajdywać kolejnego ogólnego mechanizmu ponad RPC – pisze na liście dyskusyjnej – *Jeśli* za dziesięć lat rzeczywiście skończymy z pół tuzinem różnych sposobów pobierania informacji, *nadal* będziemy mogli je zastąpić nowym RPC spełniającym ich zadanie…
Jérémie Koenig odnalazł pewne problemy podczas dostarczania sygnałów — okazuje się, że nie są dostarczane zgodnie z oczekiwaniami. Roland McGrath, autor kwestionowanego kodu, dokonał pewnego spostrzeżenia na ten temat: – Nie chodzi o to, że to jest błąd, po prostu Hurd nigdy nie był zgodny ze specyfikacją POSIX-1996, która dotyczy semantyki sygnałów wielowątkowych. – wyjaśnia – Implementacja hurdowa jest starsza niż owa specyfikacja. – W następnej wiadomości kontynuuje: – *Semantyka sygnałów w Hurdzie jest obecnie wyraźnie określona. Nie jest zgodna z POSIX-1996 w przypadku gdy na jeden proces przypadka wiele wątków.
Manuel Menal naprawił błąd, który występował podczas wysyłania deskryptorów plików posiadających SCM_RIGHTS przez gniazda PF_LOCAL. Ustalił ponadto, iż ów błąd powodował, że separacja praw demona SSH nie działała na GNU/Hurdzie — obecnie opisywany błąd został naprawiony, można już używać ustawienia UsePrivilegeSeparation yes.
Na koniec — we właściwym ku temu miejscu — przypomnijmy, że krążą plotki iż nasi koledzy z wydziału ds. Duke Nukem Forever znów poważnie biorą się do roboty. Zobaczymy. 🙂
„Thomas Schwinge przeniósł kilka pakietów (gopherfs,”
O bosze 🙂
To oni jeszcze z tego korzystają? Ja używam internetu jakoś od 1998 roku i nigdy tego nie używałem, bo już wtedy było to przestarzałe 🙂
Ale robienie jeszcze jako systemu plików? Przecież starsze przeglądarki to obsługiwały – wystarczyłoby wrzucić jakąś antyczną mozille.
Jak deweloperzy HURD’a będą się zajmować takimi pierdołami, to ten system będzie wydawany do końca świata i jeden dzień dłużej.
No dobrze – z takich przyziemnych spraw – jest już może obsługa kart dźwiękowych? Kiedyś sterowniki SCSI były wzięte z Linuksa i leciały przez emulacje API. Coś się zmieniło? Czy HURD jest używalny? Czy w czymś wyprzedza inne systemy? (poza tym „rewolucyjnym” designem, dzięki któremu jest najdłużej robionym OS’em na świecie)
Bez przesady w ostatnim roku alternatywne osy bardzo skoczyły do przodu , nawet zaniedbywany Aros , HelenOS czy Minix urwały swoje kawałki tortu więc czemu Hurdowi ma się nie udać ?
Mimo nazywania jego devów gnu-nazistami xD szczerze im kibicuje , bo chcę aby można było ich rewolucyjne koncepcje implementować w innych osach czy na rzeczywistym sprzęcie.
Widzę że w newsie o Hurdzie masz więcej do powiedzenia niż w tym który jest na głównej i dotyczy BSD. Właściwie nie dziwi mnie to specjalnie, ale dość dobrze podsumowuje twoją osobowość.

One thing I have actually noticed is that often there are plenty of fallacies regarding the lenders intentions if talking about foreclosure. One delusion in particular is always that the bank would like your house. The bank wants your hard earned money, not your home. They want the bucks they gave you along with interest. Averting the bank will simply draw a foreclosed final result. Thanks for your write-up.

Thanks for your useful article. One other problem is that mesothelioma cancer is generally a result of the inhalation of dust from asbestos, which is a dangerous material. It really is commonly viewed among personnel in the engineering industry who definitely have long experience of asbestos. It’s also caused by living in asbestos covered buildings for a long time of time, Family genes plays an important role, and some folks are more vulnerable on the risk when compared with others.
