branch에서 작업한 commit을 master에 합치기

git checkout -b workbranch master

git add files

git commit 

git checkout master

git merge --squash workbranch

git commit

git push

rebase 하는 방법...

1)git clone

2)해당 codereview 를 checkout 하면 (no branch) 생김

3)git rebase master

4)conflict난 file 해결

  > git add file

5)git rebase --continue

  > git commit --amend

6)git checkout master

7)git reflog

8)git merge commitID_num

9)git push origin master:refs/for/master

-----------------삼바 서버 설정------------------

sudo apt-get install samba samba-tools system-config-samba

sudo smbpasswd -a username

sudo vi /etc/samba/smb.conf

Add 

[Pictures]

path = /home/username/<folder_to_be_shared>

sudo /etc/init.d/smbd restart

----------------- NFS 서버 설정 --------------------------

$ sudo mkdir -p /share/platform/sub_folder

$ sudo apt-get install nfs-kernel-server

$ sudo sh -c 'echo "/share/platform/sub_folder *(rw,sync,nohide,no_root_squash,no_subtree_check)" >> /etc/exports'

$ sudo /etc/init.d/nfs-kernel-server restart

target에서 nfsroot 설정

------------------------------------------------------------------------------------------------------

In Synology management UI

1) Enable NFS.

2) Go to shared folders - privileges setup and for the folder you wish to share enable the guest account under local users to have read/write access.

3) Go to NFS privileges and select;

Hostname or IP = *

Privilege = Read/Write

Root Squash = Map to guest

4) With the changes made reboot your NAS.

5) In your WDTV NET.mounts file add the line (video being the name of the shared folder with the privileges set)

xmount 192.168.1.100:/volume1/video volume1 nfs

g_timeout_add 의 경우  g_source_remove 쪽에 문제가 있는 것으로 보인다.

remove - add 반복시 아래 방식이 더 안정적이다. g context 문제가 생길 시에도 바로 확인이 가능하다.

{
    GMainContext *context;
    GMainLoop *main_loop;
    GSource *source;


    /* Initialize thread support */
    g_thread_init(NULL);

    /* Create a GLib Main Context */
    context = g_main_context_new();

    /* Create a Main Loop in the context*/
    main_loop = g_main_loop_new(context,
                                FALSE);

    /* Create new timeout source to be called
     * every 5 seconds.
     * Reference count of source is 1 once created */
    source = g_timeout_source_new(TIMEOUT_MSECS);

    /* Set callback to be called in each timeout */
    g_source_set_callback(source,
                          (GSourceFunc)__timeout_func,
                          main_loop,
                          NULL);

    /* Attach the GSource in the GMainContext.
     * Reference count of source is 2 after this call */
    g_source_attach(source,
                    context);

    /* Run the main loop, until it is stopped */
    g_main_loop_run(main_loop);

    /* We did an attach() with the GSource, so we need to
     * destroy() it */
    g_source_destroy(source);

    /* We need to unref() the GSource to end the last reference
     * we got */
    g_source_unref(source);

    /* The main loop should be destroyed before the context */
    g_main_loop_unref(main_loop);

    /* Finally, destroy the context */
    g_main_context_unref(context);


    /* Done! */

    return 0;
