		# Resolv Gold Test
		The "Resolv Gold Test" targets to run automatically in presubmit, as a change
		detector to ensure that the resolver doesn't send the query or parse the
		response unexpectedly.

		## Build testing pbtext
		The testing pbtext is built manually so far. Fill expected API parameters to
		'config' and expected answers to 'result' in pbtext. Then, record the
		corresponding DNS query and response packets. Fill the packets with the \x
		formatting into 'query' and 'response' in pbtext. Perhaps have a mechanism
		to generate the pbtxt automatically in the future.

		### Using 'ping' utility to be an example for building pbtext
		Here demonstrates how the pbtext is built.

		1. Enable resolver debug log level to VERBOSE (0)
		```
		$ adb shell service call dnsresolver 10 i32 0
		```
		2. Ping a website
		```
		$ adb shell ping www.google.com
		```
		3. Get bugreport
		```
		$ adb bugreport
		```
		4. Search the log pattern as the follows in bugreport
		```
		# API arguments
		resolv : logArguments: argv[0]=gethostbyname
		resolv : logArguments: argv[1]=0
		resolv : logArguments: argv[2]=www.google.com
		resolv : logArguments: argv[3]=2

		# Query packet
		resolv : ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 29827
		resolv : ;; flags: rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
		resolv : ;; QUERY SECTION:
		resolv : ;; www.google.com, type = A, class = IN
		resolv :
		resolv : Hex dump:
		resolv : 7483010000010000000000000377777706676f6f676c6503636f6d0000010001

		# Response packet
		resolv : ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 29827
		resolv : ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
		resolv : ;; QUERY SECTION:
		resolv : ;; www.google.com, type = A, class = IN
		resolv :
		resolv : ;; ANSWER SECTION:
		resolv : ;; www.google.com. 2m19s IN A 172.217.160.100
		resolv :
		resolv : Hex dump:
		resolv : 7483818000010001000000000377777706676f6f676c6503636f6d0000010001
		resolv : c00c000100010000008b0004acd9a064
		```

		5. Convert the logging into pbtext. Then, Clear the 'id' which is 0x7483 in
		this example from 'query' and 'response' because 'id' is regenerated per
		session. The follows is result pbtext.
		```
		config {
		call: CALL_GETHOSTBYNAME
		hostbyname {
		host: "www.google.com."
		family: GT_AF_INET
		};
		}
		result {
		return_code: GT_EAI_NO_ERROR
		addresses: "172.217.160.100"
		}
		packet_mapping {
		query: "\x00\x00\x01\x00\x00\x01\x00\x00\x00\x00\x00\x00\x03\x77\x77\x77"
		"\x06\x67\x6f\x6f\x67\x6c\x65\x03\x63\x6f\x6d\x00\x00\x01\x00\x01"
		response: "\x00\x00\x81\x80\x00\x01\x00\x01\x00\x00\x00\x00\x03\x77\x77\x77"
		"\x06\x67\x6f\x6f\x67\x6c\x65\x03\x63\x6f\x6d\x00\x00\x01\x00\x01"
		"\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\x8b\x00\x04\xac\xd9\xa0\x64"
		}
		```

		## Decode packets in pbtext
		You can invoke the [scapy](https://scapy.net) of python module to extract
		binary packet record in pbtext file. Here are the instructions and example
		for parsing packet.

		### Instructions
		Run the following instruction to decode.
		```
		$ python
		>>> from scapy import all as scapy
		>>> scapy.DNS("<paste_hex_string>").show2()
		```

		### Example
		Using 'getaddrinfo.topsite.youtube.pbtxt' to be an example here.

		1. Find the packet record 'query' or 'response' in .pbtext file.
		```
		query: "\x00\x00\x01\x00\x00\x01\x00\x00\x00\x00\x00\x00\x03\x77\x77\x77"
		"\x07\x79\x6f\x75\x74\x75\x62\x65\x03\x63\x6f\x6d\x00\x00\x1c\x00"
		"\x01"
		```
		2. Run the following instruction.

		Start python
		```
		$ python
		```
		Import scapy
		```
		>>> from scapy import all as scapy
		```
		Assign the binary packet to be decoded into a variable. Beware of using
		backslash '\\' for new line if required
		```
		>>> raw_packet=\
		"\x00\x00\x01\x00\x00\x01\x00\x00\x00\x00\x00\x00\x03\x77\x77\x77" \
		"\x07\x79\x6f\x75\x74\x75\x62\x65\x03\x63\x6f\x6d\x00\x00\x1c\x00" \
		"\x01"
		```
		Decode packet
		```
		>>> scapy.DNS(raw_packet).show2()
		###[ DNS ]###
		id = 0
		qr = 0
		opcode = QUERY
		aa = 0
		tc = 0
		rd = 1
		ra = 0
		z = 0
		ad = 0
		cd = 0
		rcode = ok

		\|###[ DNS Question Record ]###
		\| qname = 'www.youtube.com.'
		\| qtype = AAAA
		\| qclass = IN
		an = None
		ns = None
		ar = None
		```

		## Running the tests
		Run the following instruction to test.
		```
		atest resolv_gold_test
		```
