Can't not load file (INKfopen issue)
Hi guys. I just got some problem when i follow the SDK Guide for The Append-Transform Plugin. i Compile plugin source code(from example folder), creating a shared library. then i copy the append-transform.so into /usr/local/libexec/trafficserver/ (the default plugin floder), then, i configer my plugin.config as the Guide mentioned mentioned :append-transform.so /home/cheng.chang/file.text
when i restart my ATS, i found error from error log. it said:[append-transform] Could not load /home/cheng.chang/file.text[append-transoform] Unable to initialize plugin
no mater i changed the path of the file. i still get same error.
After i check the source code of Append-Transform Plugin, i found the INKfopen(filename, "r") caused this problem, it's always return false i think.
So, anyone has same problem as me? Any Suggestion?
Thanks

Thanks your attention, i have find the problem caused error, the file path have to be inside of loacl folder, for example. i have file in /usr/local/temp/file.txt. when i write line in plug.config. the path have to be write like:/temp/file.txt. if i put path like: /usr/local/temp/file.txt. this will get "can't not load file " error.
Thanks again!

So, I tried this in a plugin (and I also looked at the code), and it
looks fine to me. I added this to a plugin of mine:
char buf[1024];
TSFile f = TSfopen("/tmp/conf.config", "r");
TSfread(f, buf, sizeof(buf));
printf("TSfopen() returns %d\n", f ? 1 : 0);
printf("TSfread() read %s\n", buf);
TSfclose(f);
and when run, I see
TSfopen() returns 1
TSfread() read CONFIG proxy.config.http.insert_request_via_str INT 0
(which is exactly as expected).

Is this with v2.0.1 ? Is there any chance you can try v2.1.6, or current
trunk?
