Default nameservers without port
If google's public DNS servers on Windows is used following error occurs:
Fatal error: Uncaught exception 'Amp\Dns\ResolutionException' with message 'Connection to udp://8.8.8.8 failed: [Error #0] Failed to parse address "8.8.8.8"'
The default nameservers setting:
"nameservers" => [
"8.8.8.8",
"8.8.4.4",
],
A correction could be setting port value:
"nameservers" => [
"8.8.8.8:53",
"8.8.4.4:53",
],
Optional setting is optional
My life would be eased if it were possible to set the following options on Addr\Client after instantiation and not require them in the constructor:
$socketAddr$socketPort$requestTimeout
Instances can function perfectly well with default values. More importantly, though, the Client class is generally going to be a dependency of other classes and so must be injected. By allowing at least $requestTimeout to be modified after instantiation the classes that are composed of Client instances can expose the option to modify DNS resolution timeouts.
I realize that clients currently open a UDP connection at instantiation time and hold that for the life of the object. As a result, allowing the address values to be modified would add some logic to the current code.
Amazon MySql db connection issue
I am connecting to an amazon DB from windows php 7.2.4 with following code:
https://gist.github.com/plankes-projects/d941f49bf74353f0b29700261192c639
I get DNS timeout exception when I am running it on my windows developer machine.

Everthing works fine if I am using this config with eloquent or if I am connecting to a local DB:

Setting for default timeout
Currently we allow default timeouts on Linux via /etc/resolv.conf. On Windows there's no such thing we support. It would be cool to have a global setting for the timeout I think that can be set on Windows.
Relates to kelunik/acme-client#44.
Watch resolv.conf for changes
I think we should watch /etc/resolv.conf for changes or alternatively cache the config only for a certain amount of time.

Tests on 0.8.x hang with UV enabled
Everything works fine without uv.
Update promise on CNAME following
Just like Artax uses promise updates when following redirects, amphp/dns should update the promises when following CNAME records and similar things.
fwrite can fail
The fwrite here can fail, generating a notice but continues to run in a presumably bogus state.
So I guess the code so check the return value.....and possibly suppress the warning? (shakes fist at PHP's 'error' model)
Exception:
Notice: fwrite(): send of 32 bytes failed with errno=65 No route to host in /documents/projects/github/FlickrArtaxService/vendor/daverandom/addr/lib/Addr/Client.php on line 182

Cyclic reference with loop, resolver will never be destructed
As long as the gcWatcher is not cancelled, the BasicResolver will never be destroyed as the watcher contains a reference to the resolver which is retained by the loop. The loop driver will also never be destroyed as long it has watchers. Watcher callbacks have references to the loop and the loop has references to the watchers (or events). But this is something different.
Nicer handling of PTR queries
amphp DNS doesn't handle calls like this:
yield Amp\Dns\resolve('209.141.56.29', $options = ['types' => Amp\Dns\Record::PTR])
Currently, you need to manually convert the IP address to the right PTR query:
yield Amp\Dns\resolve('29.56.141.209.in-addr.arpa', $options = ['types' => Amp\Dns\Record::PTR])
The legacy Net_DNS library has some code to handle PTR queries correctly, when the input looks like an IP address:
/*
* If the name looks like an IP address then do an appropriate
* PTR query.
*/
if (preg_match('/^(\d+)\.(\d+)\.(\d+)\.(\d+)$/', $name, $regs)) {
$name = $regs[4].'.'.$regs[3].'.'.$regs[2].'.'.$regs[1].'.in-addr.arpa.';
$type = 'PTR';
}
It would be nice for amphp to do this too.
Implement server pool
Implement the ability to fail over to other servers and/or query multiple servers at once.
Good queries failing with "Response decode error" when running multiple requests in parallel via Amp\any - Fine when running in series
Consider this simple test script:
<?php
require __DIR__.'/../vendor/autoload.php';
function format_exception(Exception $ex, $indent = 0) {
$output = get_class($ex).' - '.$ex->getMessage();
if ($ex instanceof Amp\CombinatorException) {
foreach ($ex->getExceptions() as $inner) {
$output .= "\n".str_repeat(' ', $indent). ' --> '.format_exception($inner, $indent + 1);
}
} else {
$prev = $ex->getPrevious();
if ($prev) {
$output .= "\n".str_repeat(' ', $indent). ' --> '.format_exception($prev, $indent + 1);
}
}
return $output;
}
const IPS_TO_LOAD = 2;
Amp\run(function () {
$start_ip = '209.141.56.29';
$start_ip_raw = ip2long($start_ip);
for (
$current_ip_raw = $start_ip_raw - IPS_TO_LOAD;
$current_ip_raw < $start_ip_raw + IPS_TO_LOAD;
$current_ip_raw++
) {
$current_ip = long2ip($current_ip_raw);
$ips[] = $current_ip;
$lookups[$current_ip] = Amp\Dns\query($current_ip, Amp\Dns\Record::PTR);
}
list($failed, $succeeded) = (yield Amp\any($lookups));
echo '**** ', count($failed), " failures! ****\n\n";
foreach ($ips as $ip) {
if (array_key_exists($ip, $succeeded)) {
list(list($result)) = $succeeded[$ip];
echo $ip, ': ', $result, "\n";
} else if (array_key_exists($ip, $failed)) {
$ex = $failed[$ip];
if ($ex instanceof Amp\Dns\NoRecordException) {
echo $ip, ": No reverse DNS\n";
} else {
echo $ip, ': EXCEPTION: ', format_exception($ex), "\n";
}
} else {
echo $ip, ": UNKNOWN\n";
}
}
});It sends 5 PTR lookups concurrently for a range of IP addresses. I'm seeing this fail sporadically, with different requests failing every time I run it. All failures are listed as "Decode error: Empty domain name at position 0x38"
Example output:
**** 2 failures! ****
209.141.56.27: buyvm.lamphost.cn
209.141.56.28: EXCEPTION: Amp\Dns\ResolutionException - All name resolution requests failed
--> Amp\CombinatorException - All promises passed to Amp\some() failed
--> Amp\Dns\ResolutionException - Response decode error
--> UnexpectedValueException - Decode error: Empty domain name at position 0x38
209.141.56.29: dan.cx
209.141.56.30: EXCEPTION: Amp\Dns\ResolutionException - All name resolution requests failed
--> Amp\CombinatorException - All promises passed to Amp\some() failed
--> Amp\Dns\ResolutionException - Response decode error
--> UnexpectedValueException - Decode error: Empty domain name at position 0x38
Event loop stops without resolving promise
In certain edge cases the loop stops without resolving the promise returned from BasicResolver::resolve(). Reproducible with the script from https://github.com/amphp/artax/issues/138 with a fix for the TLS hanging.
Tests fail with OPCache enabled
Quite a few tests fail with OPCache enabled, because Socket::ask yields an empty array instead of an instance of Message.
Remove amphp/file dependency
I'm only using amphp/socket and there is following dependency tree that is useless to me:
amphp/socker -> amphp/file -> amphp/sync, amphp/parallel
So after removing this dependency, my consumers will have to install 3 packages less.
Additionally, replacing it with bytestream increases performance almost 10x!

Google Fallback
Currently we fallback to Google's public DNS servers if we don't have a config. This affected probably only Windows, as we don't have /etc/resolv.conf there. On other systems, that could only happen if there is an error reading /etc/resolv.conf.
I don't like sending all DNS queries silently as a fallback to Google. If the system config can't be read, it's either a weird system not yet supported (a bug then), or something other that has to be fixed on the system. @DaveRandom mentioned he'd like to keep the fallback, as we can still continue resolving domain names, but would like to issue a warning when the default config is used.
#40 plans to deprecate the default config and I plan to remove default nameservers when we release a new major version based on Amp v2.
Please add a ๐ if you want to drop the fallback, add a ๐ if you want to keep the fallback.
Improve failure tolerance
Currently we always use the first nameserver only. If that one fails, it should retry with the next server.
Timeout not working
I've discovered the timeout mechanism isn't working. In some tests, the reactor will run forever, but most of the time the test will take about ~1 minute. The timeout value seems to be ignored. I've stepped through with xdebug, but it gets lost and i can't seem to identify the issue. Example:
$promise = \Amp\Dns\resolve('www.google.ca', ['timeout' => 100, 'server' => 'tcp://8.8.8.0:53',
'types' => Record::A, 'cache' => false ]);
try {
$result = \Amp\wait($promise);
$this->fail("Resolve did not timeout when expected {$result}");
} catch (\Exception $e) {
$this->assertInstanceOf(\Exception::class, $e);
}
I've tried with and without ev extension. I've tried with regular IP, udp scheme, smaller/larger values, cache on/off.
This is with php version 5.5.30. and amphp/dns 0.8.10
Any ideas or recommendations to get this working?

/amphp/dns/lib/DefaultResolver.php line 632, method processDecodedResponse:
private function processDecodedResponse($serverId, $requestId, $response) {
list($promisor, $name, $type, $uri, $timeout) = $this->pendingRequests[$requestId];
//...
}
$this->pendingRequests doesn't contain a value at index $requestId

Missing check whether IP version is right on resolve
Calling resolve with an IP address currently simply resolves to chat address. But it doesn't check whether it's allowed by the current "types" in $options:
var_dump(yield Amp\Dns\resolve('8.8.8.8', ['types' => Amp\Dns\Record::AAAA])); works just fine, but should result in an exception, because no records found. Or for the A โ AAAA case, we can rewrite it to an IPv6 address.
Support for Windows System DNS
We currently use 8.8.8.8 by default on Windows.
We can find the nameservers Windows uses in HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip/Parameters/Nameserver or HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Tcpip/Parameters/DhcpNameServer.

isValidHostname throws exception on valid hostnames
https://github.com/amphp/dns/blame/master/lib/DefaultResolver.php#L87
2.0.0.127.b.barracudacentral.org is a prefectly valid hostname that doesn't match the regex.
Suggest instead:
$pattern = "/^(([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\\-]*[a-zA-Z0-9])\\.)*([A-Za-z0-9]|[A-Za-z0-9][A-Za-z0-9\\-]*[A-Za-z0-9])$/i";It appears the top answer on stackoverflow is wrong: http://stackoverflow.com/questions/106179/regular-expression-to-match-dns-hostname-or-ip-address
Improve Windows configuration loader
From kelunik/acme-client#64 (comment):
The issue is in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces. Check NameServer and DhcpNameServer properties in all subkeys and remove or correct the ones which are wrong. The first one found will win, no matter if its available or not.
I think vendor\amphp\dns\lib\DefaultResolver.php#loadResolvConf function should check if the nameserver is available before using it. Or find a better way in windows to get the correct nameserver because the interfaces in this subkey where not consistent with the the interfaces listed elsewhere, also windows itself did not use this nameserver found by this function.
Support for extended macOS configurations
As stated at https://github.com/amphp/artax/issues/150, it seems that macOS resolver looks at /etc/resolver directory to get the nameserver to use for a certain TLD. For example if you put the file /etc/resolver/dev with content 127.0.0.1, the local nameserver will be used for all the *.dev domains.
This behavior should be supported by this library.
Bump the minimum version of amphp/uri
Currently the minimum supported version of amphp/uri in composer uses a broken version: ^1.0.
TypeError: Return value of Amp\Uri\Uri::getQueryParameter() must be of the type string, null returned
Can this be bumped to at least version ^0.1.1, but probably better to just use latest.
Bonus internet points if the above change is topped off with a fresh release containing the change <3
Make amphp/windows-registry a suggested dependency
As it's platform related and make vendor dir heavier for nothing when not running code on Windows.
Subtype 'Too many redirects' DnsException
dns/lib/Rfc1035StubResolver.php
Line 219 in 493d014
It would be very nice to differentiate this type of error. In my situation this difference is important as other DnsException throws are usually temporary, so the script can be rerun successfully whereas 'Too many redirections' error tend to be permanent (e.g. if there is a cyclic aliasing)
Limit cache size by default
See amphp/cache#4.
Support for LOCALDOMAIN and search
I think we currently do not support search nor LOCALDOMAIN (env variable for per-process override).
DNS resolution not working on Kubernetes
Wrong DNS server parsing
https://github.com/amphp/dns/blob/master/lib/DefaultResolver.php#L447 looks for a colon to find a port. This won't work with IPv6. I guess looking for ]: will be enough to fix it.
Make caching API async-capable
Currently the caching interface dictates that lookups must be blocking
Are dotless domains valid?
Didn't find any test that states dotless domains are invalid.
Are they valid?
If yes - then there is a bug, because resolve method throws exception for dotless domains.
If no - maybe test (and probably explicit exception message) that states dotless domains are invalid should be introduced for clarity and stability?
My use case is simple docker development environment where i want to be able to access hosts in same network by containers/services names. They are usually dotless.
DNS frequently fails on Windows
A little over 50% of the time, a async CLI application fails to start on Windows because the DNS doesn't work. Once it works, the problem does not seem to occur again, but there's a high probability it will fail unrecoverably at each process start. The operation is retried 5 times and the same error continues to occur until a new PHP process is started, when the dice is re-rolled to see if DNS is actually going to work. It doesn't matter if a process successfully ran a few seconds ago, all rolls are independent and have an equal chance of failing, despite recent successful resolutions by another process.
In BasicResolver.php line 149:
[Amp\Dns\DnsException]
All query attempts failed for example.com: Reading from the server failed, Reading from the server failed
amphp/dns v0.9.15
NoRecordException is never thrown
NoRecordException is never thrown, because of the Amp\some combinator function, see functions.php:265
"Could not find a nameserver in the Windows Registry" out-of-the-box on Windows

However, on my computer, the DNS server is at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{55de6892-f5b0-4632-aeb8-d34874155c77}\DhcpNameServer.
Instead of just looking at Interfaces\{guid}\NameServer, I think it should also look for Interfaces\{guid}\DchpNameServer.
I'm on Windows 10, using DHCP.
Random nameserver failures at start of program on Windows
This problem typically only manifests itself when the program is first run, and occurs intermittently (not guaranteed to be reproducible). In my test output (sorry about formatting), I initiate two requests that fail immediately with DNS errors and never complete. Then, a third request is sent that completes successfully. All three requests are made to the same address (http://example.com). A further 50 requests are made to the same address that complete without error; only the first two (initiated at the same time, at the beginning) fail.

Invalid promise resolution for cached failures
We currently cache in case of no results for a maximum of 5 minutes. The first invocation results in a ResolutionException (should actually be NoRecordException, see #25). All later invocations result in an successfully resolved promise yielding an empty array. Instead there should be the same outcome as for non-cached DNS requests (the same exception).
API Refactoring
With v0.8.8 we introduced classes as resolvers: v0.8.7...v0.8.8
We should modify the API to drop the nameserver options from Amp\Dns\query and Amp\Dns\resolve. If anyone needs a different resolver, they should just go ahead and create a new resolver object with the nameserver as argument and execute their query then.
BasicResolver configLoader parameter
Hello :)
There's an issue with the setting of the configLoader in the BasicResolver constructor where incorrect precedence means the constructor always assigns a WindowsConfigLoader if you try to supply your own.
PR #61 fixes this
Support for RES_OPTIONS
We should add support for the RES_OPTIONS environment variable. The way it works is described in the resolv.conf man page.
DNS resolution failed -- possibly cache bug
We get an Amp\Dns\ResolutionException with the message
"DNS resolution failed: www.google.com"
These are the last couple of lines from our stack-trace:
#0 ...\vendor\amphp\dns\lib\Client.php(298): Amp\Dns\Client->completePendingLookup(0, NULL, 3)
#1 ...\vendor\amphp\dns\lib\Client.php(220): Amp\Dns\Client->completeRequest(Array, NULL, 3)
#2 ...\vendor\amphp\amp\lib\NativeReactor.php(184): Amp\Dns\Client->Amp\Dns\{closure}(Object(Amp\NativeReactor), 2)
#3 ...\vendor\amphp\amp\lib\NativeReactor.php(123): Amp\NativeReactor->executeAlarms()
It seems that the problem originates in lib/Client.php on line 311 where $cacheHit is true but $addr is NULL. Google is reachable by DNS from the environment in question.
TXT records are checked to be valid hostnames
See kelunik/acme#11. I don't know whether we should introduce a flag like validate_hostname which can be set to false or any other mechanism.
zend_mm_heap corrupted on centos guest
Repo script is below. It's basically example 2 with an extra host name inserted.
The environment is Centos 6.4 with self-built version of PHP 5.6.2. It is sitting inside a vagrant box hosted on Mac OSX .
The hostname is being resolved by a hosts file on the host, not the guest. I'm going to attempt to capture the packets being sent between guest/host.
The output is

DNS timeout causes array out of bounds error.
It looks like when a DNS lookup times out, the code doesn't handle it gracefully. i.e. when
$this->completePendingLookup($id, null, ResolutionErrors::ERR_SERVER_TIMEOUT);
is called, it causes an out of bounds error in AddrDnsResolver.php on line 49:
Error message: "Undefined offset: 3" aka ERR_SERVER_TIMEOUT

Reset state / Accessor
It must be possible to reset the state. If you want to start your unit tests with a clean reactor, DNS won't work in when used in multiple tests, because the server is still loaded but doesn't receive any watcher events anymore, because the old reactor where the watchers where registered, doesn't exist anymore.
Additionally, it's currently not possible to mock DNS.
