svn up 하다가 'password for '(null)' GNOME keyring 나오

codecat@codecat-PC ~/workspace/kernel_src/trunk $ svn up
Password for '(null)' GNOME keyring:
svn: OPTIONS of 'https://xxx.xxx.xxx/svn/kernel_src/trunk': 인증에 실패하였습니다: Could not authenticate to server: rejected Basic challenge (https://xxx.xxx.xxx)

위와 같은 상황은 subversion이 gnome-keyring을 쓰려고 했는데 무슨 사유로 제대로 동작하지 않기 때문이다.

이를 해결하기 위해선,

rm ~/.gnome2/keyring/login.keyring

을 실행하여 keyring 사용을 막으면 된다.

svn up 하다가 password store한다고 할 때 진행 안될 때

$>svn up

...

can only be stored to disk unencrypted! You are advised to configure
your system so that Subversion can store passwords encrypted, if
possible. See the documentation for details.

You can avoid future appearances of this warning by setting the value
of the 'store-plaintext-passwords' option to either 'yes' or 'no' in
'/home/codecat/.subversion/servers'.
-----------------------------------------------------------------------
Store password unencrypted (yes/no)? yes
Please type 'yes' or 'no': yes
Please type 'yes' or 'no': 예

한글 설정이 되어 있으면 위와 같이 'yes'로 해도 안 넘어가고 다시 물어본다. 그럴 때, '예' 라고 하자. -___-;;;;;;

boot memory allocator 의 필요성

boot memory allocator

컴파일 타임에 커널에서 사용하는 그 많은 structure들을 초기화 시킨다는 것은 불가능하다. 그런 structure들을 초기화 시켜주기 위해서는 메모리가 필요한데 그 이유는 physical page allocator조차 자기자신을 초기화 하기 위해서는 메모리가 필요하기 때문이다.

iPhone 에서 작성된 글입니다.

구조체 초기화 방법

출처: http://kldp.org/node/71304

typedef struct aa = {

}AA;
 
/* 1번 방법 */
AA a = {

    2
};
 
/* 2번 방법 */

1은 ANSI 표준, 2는 ISO C (C99) 표준, 3은 GCC 확장 기능입니다.

defunct 프로세스 죽이기

defunct 라고 나오는 프로세스는 우리가 흔히 알고 있는 Zombie 프로세스로 부모 프로세스에서 아직 wait을 부르지 않은 상태이다.

ps 시 defunct라고 나오는 프로세스를 죽일라면 부모 프로세스를 찾아서 부모 프로세스를 죽여야 한다. 부모가 죽은 고아 프로세스는 결국 init프로세스에서 회수에서 처리하기 때문이다.
