얘는 udev management tool 이라고 하니

이걸 uinput이 아니라 udev라고 하나 따로 파야하나..?

$ udevadm info -a -n /dev/input/event24

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

$ udevadm info -a -n /dev/input/event25

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

gdb 사용법

오랫만에 쓰려니 다 까먹어서 다시 조사

빌드

-g 옵션을 통해 디버깅 심볼을 넣어준다.

$ gcc -g tt.c

이거 안하면 소스코드가 안나옴

Reading symbols from ./a.out...
(No debugging symbols found in ./a.out)
(gdb) l
No symbol table is loaded. Use the "file" command.

gdb 실행 (인자 없이)

$ gdb ./a.out

$ gdb
(gdb) file ./a.out

gdb 실행 (인자 필요시)

$ gdb --args ./a.out arg1 arg2

브레이크 포인트 설정 및 소스 보기

소스는 list (혹은 소문자 l) 과 라인수를 넣고

브레이크 포인트는 b로 추가한다. b 뒤에는 라인수 혹은 함수 명을 넣으면 된다.

브레이크 포인트 목록 확인은 info b를 통해 가능하다.

clear 를 통해 b 명령을 통해 추가하는 것과 정반대로 삭제가 가능하고

delete(소문자 d) 명령은 info b의 num 을 이용하여 삭제한다.

디버깅 시작, 디버깅 제어

run을 통해 시작하고 인자가 필요할땐

(gdb) r 1 2 3

처럼 인자를 공백으로 띄워서 넣어준다.

c는 break 포인트 까지 실행(continue)

print 를 이용하여 변수 값을 출력할수 있다.

r을 눌러 실행하나 main() 함수에서 한번 브레이크 걸리고

c를 눌러 진행하지만 10 라인에 브레이크가 걸려있어 한번 멈추고

c를 눌러 진행하지만 조건부 브레이크에 의해 idx가 200인 경우에 멈춘다.

smb.conf 멀티채널 지원

문득 생각나서 검색하는데 실험적인 기능.. smb3 멀티채널

에이 설마 저런게 옵션이겠어?goTsmsep

EXPERIMENTAL FEATURES
=====================

SMB3 Multi-Channel
------------------

Samba 4.4.0 adds *experimental* support for SMB3 Multi-Channel.
Multi-Channel is an SMB3 protocol feature that allows the client
to bind multiple transport connections into one authenticated
SMB session. This allows for increased fault tolerance and
throughput. The client chooses transport connections as reported
by the server and also chooses over which of the bound transport
connections to send traffic. I/O operations for a given file
handle can span multiple network connections this way.
An SMB multi-channel session will be valid as long as at least
one of its channels are up.

In Samba, multi-channel can be enabled by setting the new
smb.conf option "server multi channel support" to "yes".
It is disabled by default.

[링크 : https://www.samba.org/samba/history/samba-4.4.0.html]

진짜냐?!

4.4.0 에서 실험 기능으로 도입되고, 4.15 에서부터는 기본값으로 바뀐듯?

server multi channel support (G)
This boolean parameter controls whether smbd(8) will support SMB3 multi-channel.

This parameter was added with version 4.4.

Note that this feature was still considered experimental up to 4.14.

Due to dependencies to kernel APIs of Linux or FreeBSD, it's only possible to use this feature on Linux and FreeBSD for now. For testing this restriction can be overwritten by specifying force:server multi channel support=yes in addition.

This option is enabled by default starting with to 4.15 (on Linux and FreeBSD).

Default: server multi channel support = yes

git revert

reset은 아예 없애는거라 내 취향은 아니고

revert 가 딱이긴 한데 의미가 내가 생각하던 것과는 조금 달랐다

예를 들어

git log 에서

hash 1111

hash 2222

hash 3333

hash 4444

git revert 2222 라고 하면

hash 2222 에서 했던 녀석만을 되돌리게 된다.

정리 하자면

revert 는 "hash 의 해당 commit을 돌린다" 이기 때문에

돌아가고 싶은 커밋이 아니라

없애고 싶은 커밋을 명시해야 한다.

man page 에도 존재하는 커밋을 되돌린다고 되어있다.

git-revert - Revert an existing commit

Synopsis
git revert [--edit | --no-edit] [-n] [-m parent-number] [-s] <commit>

Description

Given one existing commit, revert the change the patch introduces, and record a new commit that records it. This requires your working tree to be clean (no modifications from the HEAD commit).

Note: git revert is used to record a new commit to reverse the effect of an earlier commit (often a faulty one). If you want to throw away all uncommitted changes in your working directory, you should see git-reset(1), particularly the --hard option. If you want to extract specific files as they were in another commit, you should see git-checkout(1), specifically the git checkout <commit> - <filename> syntax. Take care with these alternatives as both will discard uncommitted changes in your working directory.

[링크 : https://linux.die.net/man/1/git-revert]

만약 돌려야 한다면 한번에 될진 모르겠지만 1111, 2222를 revert 해야 할지도? (확인필요)

$ git log --oneline
17b787d bug3 fixed
1fefb57 bug2 fixed
8b3560b bug1 fixed
784065c feature1 developed
...
이제 우리는 이러한 버그 수정을 없애고 저장소를 bug1 fixed 상태 이전의 상태로 되돌리기로 결정했습니다.

따라서 --no-commit 옵션과 함께 git revert 명령을 사용할 수 있습니다. 명령 구문은 git revert --no-commit <commit>입니다.

따라서 완료된 버그 수정의 세 커밋을 되돌리려면 다음과 같이 해야 합니다.

$ git revert --no-commit 17b787d784065c
$ git revert --no-commit 1fefb57
$ git revert --no-commit 8b3560b

[링크 : https://www.delftstack.com/ko/howto/git/git-revert-multiple-commits/]

[링크 : https://medium.com/@rnrjsah789/git-revert-4c569366a77b]

[링크 : https://www.inflearn.com/community/questions/172695/%EC%97%AC%EB%9F%AC%EA%B0%9C%EC%9D%98-%EC%BB%A4%EB%B0%8B%EC%9D%84-revert?srsltid=AfmBOoo4CTQkAtobmxI0lo6YlKOM1mC1_XZ7rhbI66F8q7CUayTbRIDG]

git revert를 하면 자동으로 커밋메시지를 생성해서 커밋하는데

여러개 돌릴때 마다 메시지 남기면 번거로우니 쭈르르르륵 되돌려 버릴땐 -n 옵션 주면 된다고 한다.

-n, --no-commit
Usually the command automatically creates a commit with a commit log message stating which commit was reverted. This flag applies the change necessary to revert the named commit to your working tree and the index, but does not make the commit. In addition, when this option is used, your index does not have to match the HEAD commit. The revert is done against the beginning state of your index.
This is useful when reverting more than one commits' effect to your index in a row.

gdb attach

stm32도 붙이는데 리눅스에서도 작동중인 녀석을 디버그 할 수 있나 찾는데

그냥 pid 옵션주면 된다고

12년전 글이라서 한번 해봐야겠다.

-p는 gdb 옵션

attach 는 gdb 인터프리터내 명령어

gdb -p 12271
gdb /path/to/exe 12271

gdb /path/to/exe
(gdb) attach 12271
