利用 ASCIIFlow 來幫 webModule 的 InitWeb() 畫個流程示意圖

繼續追 ApplyWebSetting()
webcfg.c
static int ApplyWebSetting(int flag, int index, void* pStruct, int structSize) {
sWebConfig *pCfg = (sWebConfig *)pStruct;
SysSaveBinaryFile(WEB_TMP_BIN_FILE, pCfg, sizeof(*pCfg));
if (!IsBootInitProcess()) {
LocSaveConfigTxt(WEB_TMP_CFG_FILE, pCfg);
SysCopyFile(WEB_TMP_CFG_FILE, WEB_ETC_CFG_FILE);
}
ICOS_msg_sendto(MODULE_WEB,MODULE_WEB,pCfg,sizeof(sWebConfig),ICOS_UCAST_MODULE_APPLY);
return ICOS_SUCCESS;
}

追 ICOS_msg_sendto(MODULE_WEB,MODULE_WEB,pCfg,sizeof(sWebConfig),ICOS_UCAST_MODULE_APPLY)
icos_ipc.c
int ICOS_msg_sendto(int src_id, int dst_id, void *data, unsigned short data_sz, unsigned short event_id)
{
int sending_sz = 0;
int fd=-1, rc=0;
PRO_EVENT promsg, *pmsg=NULL;
pmsg = &promsg;
pmsg->src_id = src_id;
pmsg->dst_id = dst_id;
pmsg->msg_len = data_sz;
pmsg->event_id = event_id;
pmsg->usret[0] = 0;
if (data_sz>0)
memcpy(pmsg->msg, data, data_sz);
sending_sz = MSG_HEADER_LEN+data_sz;
fd=socket(AF_UNIX, SOCK_DGRAM, 0);
if (fd>=0)
{
struct sockaddr_un to;
to.sun_family=AF_UNIX;
snprintf(to.sun_path, UNIX_PATH_MAX, "%s/%s", PRO_USOCK_PATH, USOCKNAME_EVENT);
rc=sendto(fd, pmsg, sending_sz, MSG_DONTROUTE|MSG_DONTWAIT, (struct sockaddr *)&to, sizeof(struct sockaddr_un));
close(fd);
goto END_RETURN;
}
rc = -2;
END_RETURN:
if(data_sz > MAX_MSG_LEN && pmsg)
free(pmsg);
return rc;
}
ICOS_msg_sendto() 利用了 sockets 的技術
參考 Linux Programming Interface - 56. Sockets: Introduction
Sockets are a method of IPC that allow data to be exchanged between applications, either on the same host (computer) or on different hosts connected by a network.
使用 ICOS_msg_sendto() 的角色相當於一個 Client
那誰是 Server 的角色呢?
Server 提供了甚麼服務呢?

M300 是由 icospromsg 扮演 Server 的角色
static int uscok_delete(int usock_fd)
{
...
close(usock_fd);

return 0;
}
static int uscok_create()
{
struct sockaddr_un skadr_un;
int svrsock;
svrsock = socket(AF_UNIX, SOCK_DGRAM, 0);
skadr_un.sun_family = AF_UNIX;
sprintf(skadr_un.sun_path, "%s/%s", PRO_USOCK_PATH, USOCKNAME_EVENT);
svrsock = socket(AF_UNIX, SOCK_DGRAM, 0);
...
bind(svrsock, (struct sockaddr*)(&skadr_un), sizeof(struct sockaddr_un));
...
return svrsock;
}
int main(int argc, char **argv)
{

usock_fd=uscok_create();
while (!G_loop_exit)

uscok_delete(usock_fd);
exit(0);
return 0;

ariel 反應 frimware upgrade 還是有問題
ariel 表示從 browser 的 console 看到
TypeError: Cannot read property 'curr_time' of undefined
at firmware.js:68
...
我試著分析一下目前的 firmware.js
function firmwareController($route, $scope, $timeout, $location, icos, Upload, progress) {
var vm = this;
vm.progress = progress;
vm.upgrade = function(_file) {
if (_file) {
...
Upload.upload({ url: 'api/firmwareUpload', data: data })
.then(function(resp) {
vm.progress = resp.data.info;
return icos.firmware.upgrade();
})
.then(function(resp) {
...
vm.timeout_2sec();
});
}
}
var timer_2sec;
vm.timeout_2sec = function () {
timer_2sec = $timeout(2000);
timer_2sec.then(function () {
icos.firmware.progress()
.then(function(response) {
vm.progress = response.data.progress;
var busy_sec = (Date.parse(vm.progress.curr_time) - Date.parse(vm.progress.init_time))/1000
...
});
});
}
}
當 vm.progress.curr_time 不存在的狀況下的確會造成問題

發現是被我的 local.conf 害的
IMAGE_INSTALL_append += "nfs-utils vim jq curl"
目前 git server 上並沒有把 jq 加上去
也就是從 git server checkout 的 code build 完並沒有 jq 這個 tool 可以用
這會導致使用 jq 的 shell script 失敗
我先把自己的 local.conf 刪掉
把目前 Local 端的修改刪除
修改 prosrc_0.1.bb - 加上 jq

繼續 trace
M300 是由 icospromsg 扮演 Server 的角色
那 icospromsg 是怎麼處理來自於 ApplyWebSetting() 送來的 message 呢?
icospromsg.c
int main(int argc, char **argv)
{
int usfd = -1, maxfd=0;
int sel_ret = 0, read_bytes=0;
struct timeval timeout;
fd_set rdset;
int usock_fd;
static unsigned char *msg_buffer=NULL;
usock_fd=uscok_create();
usfd=usock_fd;
fcntl(usock_fd, F_SETFD, FD_CLOEXEC);
msg_buffer = (unsigned char *)malloc(FULL_MSG_LEN);
while (!G_loop_exit)
{
timeout.tv_sec = 1;
timeout.tv_usec = 0;
FD_ZERO(&rdset);
FD_SET(usfd, &rdset);
maxfd=usfd;
proc_FdSet(&rdset, &maxfd);
sel_ret=0;
sel_ret=select(maxfd+1, &rdset, 0, 0, &timeout);
if (sel_ret > 0)
{
if (FD_ISSET(usfd, &rdset))
{
PRO_EVENT *pmsg=NULL;
unsigned char *sp=msg_buffer;
read_bytes = recv(usfd, sp, sizeof(PRO_EVENT),MSG_DONTWAIT | MSG_NOSIGNAL);
pmsg = (PRO_EVENT*)sp;
if (pmsg->dst_id == 0) // 0: means broadcast
{
BroadcastHandle(pmsg);
}
else
{
NotifyHandle(pmsg);
}
}
}
}//End_while
}
ApplyWebSetting() 送來的 message 會觸發 icospromsg 的 NotifyHandle()
icospromsg.c
int NotifyHandle(PRO_EVENT *pmsg)
{
int res=0;
sIcosModule *pIcosModule;
pIcosModule=GetIcosModule(pmsg->dst_id);
if (pIcosModule->NotifyHandler)
{
res=pIcosModule->NotifyHandler(pmsg);
}
return res;
}
會發現 webModule 的 ApplyWebSetting() 利用 ICOS_msg_sendto() 把 message 送到 icospromsg
然後 icospromsg 只是透過 message 內含的資訊又把 webModule 的 notify_web() 叫起來做事
不過要記住 webModule 不過是個 icos library
sIcosModule webModule={
"web", // Name
InitWeb, // Init
ExitWeb, // Exit
ApplyWebSetting, // Apply
GetWebSetting, // GetSetting
SetWebSetting, // SetSetting
VerifyWebSetting, // VerifySetting
0, // GetStatus
0, // GetStatus
facotry_default_web_setting,
0,//period_ddns,
notify_web,
msgcb_web,
termcb_web,
};
要有人呼叫才會做事的
所以重點在於是誰用它來做事
再回去看 rc.local
...
/usr/sbin/icospromsg &
/usr/sbin/icosconfig bootinit
...
icospromsg 先被叫起來常駐在背景執行
icosconfig bootinit 在被執行的當下
icospromsg 已經準備好處理任何利用 ICOS_msg_sendto() 所送來的 message 了

直接從第一行看起 1487572072[20170220 6:27:52] [notify_web:871]IN(E82|S44|D44)
這是由目前 webcfg.c 的 第 871 行的 WEB_INFO 所打印的
#define WEB_INFO(FMT, ARG...) IPC_filelog_v2(WEB_LOG,IPCF_LOGMAX, __FUNCTION__, __LINE__,IPCFv2_SHOW_TIME, FMT, ##ARG)

}
來看 1487572072[20170220 6:27:52] [notify_web:871]IN(E82|S44|D44) 裡的 (E82|S44|D44)
先看 E82 - event_id = 82
定義在 icos_shm.h

} ICOS_EVENT_ID_E;
E82 表示 event_id = ICOS_UCAST_MODULE_APPLY
再看 S44 - src_id = 44
icos_module.h

S44 表示 src_id = MODULE_WEB
再看 D44 - dst_id = 44
D44 表示 dst_id = MODULE_WEB
簡單說第一行 1487572072[20170220 6:27:52] [notify_web:871]IN(E82|S44|D44) 表示
- event_id =
ICOS_UCAST_MODULE_APPLY - src_id =
