TypeError: Cannot read property 'name' of null #1105

greghart · 2016-08-09T19:28:56Z

First off, thanks for the library! Overall it's been incredibly performant and straightforward to use. I am running into one issue which may be an issue with the library, though it's a bit hard to follow the protocol for me so my usage may be off as well.

I'm running into an uncaught error during the parseComplete handler in client.js (https://github.com/brianc/node-postgres/blob/v6.0.1/lib/client.js#L131).

I am doing a direct connect against the pool and then utilizing pg-query-stream

pool.connect().then(function(client){
  stream = client.query(new QueryStream(query, null));

  stream.on('error', function(streamError){
    stream.close(function(closeError){ 
      // What to do with a close error? At this point stream is already hosed :shrug:
      client.release(streamError);
    }
  });

  stream.on('close', function(){
    client.release();
  }); 
});

At some point during my app's life cycle, I get an uncaught error

TypeError: Cannot read property 'name' of null
    at null.<anonymous> (/var/app/current/node_modules/pg/lib/client.js:139:26)
    at emit (events.js:107:17)
    at Socket.<anonymous> (/var/app/current/node_modules/pg/lib/connection.js:121:12)
    at Socket.emit (events.js:107:17)
    at readableAddChunk (_stream_readable.js:163:16)
    at Socket.Readable.push (_stream_readable.js:126:10)
    at TCP.onread (net.js:540:20)

So obviously activeQuery is becoming null, and I am trying to narrow down why I would receive a parseComplete event when the active query is null.

According to my logs, the stream is not emitting an error, and seems to be closing normally. Therefore it seems like the connection client is getting a readyForQuery or end event, and then right after that getting the parseComplete event. Any idea why this would be happening, or see any issues with my usage? Thanks for any help you can give! I'll keep looking into it as well.

The text was updated successfully, but these errors were encountered:

vitaly-t · 2016-08-10T20:09:03Z

I wonder, if the same error would occur within pg-promise, if you follow the example...

At least this would help ruling out some reasons of why this is happening...

brianc · 2016-08-10T20:12:27Z

@greghart interesting error - any way you could include the query & some data so I could try to reproduce it here? Maybe using generate_series or something if you need lots of data?

dynajoe · 2017-02-24T17:59:39Z

I'm having a similar issue. For me it seems to be related to parameterized queries.

.query('SELECT $1', ['a'])

Do you have any further findings @greghart

dynajoe · 2017-02-24T18:37:38Z

I may have found something promising. I tried to use a new client object with the original in the prototype chain. I did this because I didn't want client.release() to be called from child queries within a transaction.

I did something like this: (using lodash _.create)

const new_client = _.create(client, {
   release: function () { /* noop */ }
})

new_client.query('SELECT 1')

charmander · 2017-02-25T03:21:26Z

I did this because I didn't want client.release() to be called from child queries within a transaction.

Call client.release() in a predictable manner, then? Bluebird’s resource management might help.

jordandouglaswhite · 2017-02-26T15:32:45Z

I've been having the same issue but only on my live site, once every few hours.
My logs would always show that I received 2 requests to run the same query within about 5 ms - always 1 after another (no other queries in between).
I don't know if the parameters are the same because I don't log them.

One would then get executed and the second would crash.
It would usually happen again within a minute if I attempted to restart that application without restarting all the others that communicated with it. Basically, some combination of requests caused the issue to appear.

I haven't been able to replicate this offline.
To me at this point, it looks like a race condition and maybe some kind of reference error (destroying the activeQuery on the wrong client).

I switched to pg-native and the problem appears to have stopped (over 12 hours with no issues).

nemo · 2017-03-05T20:34:25Z

Having this issue. I had switched away from pg-native cause it was giving headache as well.

Only happens on first-start. The second time pg is used, the error goes away. The "race" condition is that it happens always at first.

So part of our production push right now is to hit the servers ourselves first before we let users use them so they don't get this error. Which is a hack of a fix.

Anyone was able to fix this?

hvrauhal · 2017-04-07T15:03:58Z

Just had this issue occur with connect-pg-simple configured pretty much as described in the advanced example of https://github.com/voxpelli/node-connect-pg-simple#usage.

brianc · 2017-05-24T16:04:34Z

Do any of y'all have a small script I can use that will likely reproduce this? Also are you using pg or pg-native? This is really perplexing but really crappy & I want to get it fixed if possible. I've used node-postgres for years on many systems in production and never seen this...so I'm not sure what exactly it could be.

@nemo gah that fix is gross - sorry you have to do that. You're using normal pg and what exact version of node are you using?

andyatmiami · 2017-08-28T17:00:18Z

My application (very rarely) has experienced this problem as well. We have unfortunately been unable to distill it down to a simple script/app that can reliably reproduce, but general observation so far seems to indicate this happens when there is a connection issue with the database.

@brianc : I can completely understand the need to be able to reproduce in order to fix - but what are your thoughts on a short term fix to at least check to make sure activeQuery is a valid object before trying to reference the name property? Given the inability for client applications to handle this error in any way... and its drastic consequences - would be great if some form of incremental improvement could be delivered...

https://github.com/brianc/node-postgres/blob/master/lib/client.js#L241 indicates access to the name attribute allows to avoid the client from re-parsing the query. I would much rather take extraneous reparsing when the alternative is uncaught exception 😇

brianc · 2017-08-28T19:27:16Z

@andyatmiami - what version of pg & pg-pool are you using? Are you using pg-cursor or pg-query-stream?

andyatmiami · 2017-08-28T19:41:17Z

"pg": "6.1.2"
"pg-pool": "1.6.0"
"node": "6.11.1"

We use parameterized queries exclusively.

FWIW:
I have a dev I am working with this afternoon who has had minimal success reproducing this - not yet reliable and not yet distilled into a simple app to run. At a high level (which I am working on refining) - we have 1 wildly expensive query (takes seconds to run), and then hammer a high load of other queries which are not long-running in parallel. Sometimes (and this is with Postgres completely stable) we see the activeQuery error fire...

brianc · 2017-08-28T23:08:20Z

Yah that's wretched that its happening. I really hope you can figure out a reproducible test case. I'd also suggest trying with the most recent version of pg & pg-pool. They both received pretty substantial internals upgrades from 6.x -> 7.x & 1.x -> 2.x respectively.

andyatmiami · 2017-08-29T15:14:52Z

@brianc : Thanks for responsiveness in issue - will post back any updates/learnings as they come available!

vedant15 · 2017-08-30T14:37:23Z

I get the same error and also sometimes a different stack which I am guessing points to the same root cause

    self.activeQuery.handleCommandComplete(msg, con)
                    ^

I see there was pull request from @spollack (#961) around this . @spollack, @jshepard it was mentioned in the PR that there was an another library causing this, do you mind sharing your findings ?

jshepard · 2017-08-30T16:48:46Z

@vedant15 I think our issue was caused by a connection leak in pre 2.0 versions of node-any-db-pool.
We ended up back porting the fix from 2.0 in a fork here

spollack · 2017-08-30T16:49:12Z

@vedant15 sorry i wish i had written down better notes on this. I can tell you however that we have been running PR #961 in prod over the past year, and as far as i recall, have had no recurrences of this crash.

vedant15 · 2017-08-30T16:54:38Z

@spollack @jshepard thanks for the quick response.

Were you guys also seeing this issue only during high loads and with statement timeouts ?

jshepard · 2017-08-30T16:55:36Z

@vedant15 pretty sure we only saw it during statement timeouts.

vedant15 · 2017-08-30T16:56:47Z

ok @jshepard , I am able to reproduce this issue on local (not always), but only when I put a considerable load on the application running queries with statement timeouts .

Thanks for all the info !

brianc · 2017-08-30T19:08:16Z

If statement timeouts are causing it I might be able to simulate them locally

vedant15 · 2017-08-30T19:24:36Z

@brianc I added some log statements on my local and whenever I am able to reproduce any of the 2 flavors of this issue, the log statements show the following:

activeQuery for a given client is set to null in Client.prototype._pulseQueryQueue
Right after this , either commandComplete or parseComplete is fired for the same client

quick question , from the comments in the code, it seems parseComplete is fired only for prepared statements , is this assumption correct ?

Also, what do you think about checking if activeQuery is null in commandComplete and parseComplete , do you see any issues with that ; I know you had some reservations about this based on the comment in #961

brianc · 2017-08-30T20:19:57Z

quick question , from the comments in the code, it seems parseComplete is fired for prepared statements , is this assumption correct ?

Yah - any query w/ parameters has a parse phase which the backend returns a parseComplete on.

Also, what do you think about checking if activeQuery is null in commandComplete and parseComplete , do you see any issues with that ; I know you had some reservations about this based on the comment in #961

I feel like that's similar to doing a try { something() } catch(e) { /* no big deal */ } and papers over what is a larger issue. I'd strongly prefer to have a reproducible test case & fix the underlying issue. Otherwise we're hiding an error and as far as the protocol operation is concerned possibly putting the connection into a bad/unknown state.

brianc · 2017-08-30T20:23:35Z

If you can send over a script that smashes a local database w/ lots of load & uses statement timeouts that might be all I need. I've gotten pretty decent at triangulating issues in the connection after all these years. 😝

brianc · 2017-08-30T20:25:24Z

something like:

const { Pool } = require('pg')
const async = require('async')

async.times(100000000, function(i, next) {
  pool.query('pg_sleep(100)')
  pool.query('SELECT $1::text as name', ['foo'], next)
})

or something? I'm missing where to define the statement timeout and if that reproduces the issue in your environment though ⁉️

vedant15 · 2017-08-30T20:27:14Z

@brianc let me see if I can come up with a script which can reliably reproduce this (reliably being the keyword 😛 ) . I will keep you posted

brianc · 2017-08-30T20:28:36Z

sweet - even if i need to run the script for a long time or over and over to reproduce the issue I should be able to work with it and narrow down where things are going amiss

vedant15 · 2017-08-30T22:41:21Z

So .. my initial attempts to recreate it via a script has failed. I will try a couple of ideas to see if I can make it work .. 😞

dynajoe · 2017-08-30T23:17:30Z

I believe the code I posted above(6 months ago) reproduced the error. Working backward from that may find the root cause.

brianc · 2017-08-31T01:59:10Z

@joeandaverde I appreciate what you put above, but it's not quite enough for me to repro easily over here. can you post up a more complete/executable example? neither of your examples above are executable "out of the box" and I'm not sure I follow what "working backwards" entails.

kibertoad · 2018-11-16T22:12:29Z

@daveisfera If you could create a failing test against current master, that would be super helpful.

pankleks · 2018-11-24T11:26:55Z

I have same problem:
Cannot read property 'handleCommandComplete' of null

pg node: 7.6.1

charmander · 2018-11-25T01:28:11Z

@pankleks when?

pankleks · 2018-11-26T10:29:46Z

@charmander hard to tell, but probably related to timeout from db.

timotm · 2019-02-20T11:42:14Z

After having stumbled into this in our production code, I tried to generate a little script to reproduce. I put the script in https://github.com/timotm/pg-bug . It seems to have something to do with timing as CPU load affects the reproducibility, and on a slower machine it reproduces more often than on a faster machine. (adjusting the number of yes commands in the background might thus have an effect)

Running it three times in row in my machine, I got three different errors:

timotm · 2019-02-20T15:33:40Z

With console.log debug technology it seemed that the flow in the crash was something like

open transaction
set local statement timeout
execute prepared INSERT statement
the above INSERT statement times out
pg receives CommandCompleted
pg sends Sync
pg receives ErrorResponse
pg sends Sync
pg receives ReadyForQuery with status E (for Sync after CommandCompleted)
client dequeues the next statement (in this case ROLLBACK), setting self.activeQuery
pg receives ReadyForQuery with status E (for Sync after ErrorResponse)
client dequeues the next statement, setting self.activeQuery (or sets to null if no next statement)
pg receives CommandCompleted for ROLLBACK but self.activeQuery points to the wrong query or null

I tried ignoring the first ReadyForQuery and only reacting to the second one and could no longer reproduce the null crashes.

An interesting observation: after having upgraded the production machine to PostgreSQL 11.2 (Debian 11.2-1.pgdg90+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516, 64-bit, the problem no longer exists.

Also, on a colleague's machine running PostgreSQL 11.1 on x86_64-apple-darwin17.7.0, compiled by Apple LLVM version 10.0.0 (clang-1000.11.45.5), 64-bit we couldn't reproduce this with the script.

n-clark · 2019-04-28T03:23:35Z

Started getting this error after using the query_timeout config parameter, pg 7.10.0

Repro steps for me, using this config:
{ query_timeout: 10 * 1000, max: 32, min: 8 }

Steps: lock a table in the database and then issue queries against that table, so that they all time out; doesn't have to be very fast, 1-2 per second will do. I get the crash very quickly, somewhere after around 10 to 100 query timeouts.

Other timing information, if it's relevant: the database and node-postgres servers are on separate machines but the ping rtt is very low, 0.5 - 1ms.

I was experiencing this issue with pg-query-stream and downgrading to pg@7.4.1 fixed it. Not sure what changed but maybe that is something to look into?

iancamp · 2019-11-05T02:42:30Z

I'm also using pg-query-stream@2.0.1 with pg-promise@9.3.3. I tried downgrading pg-promise to a version that uses pg@7.4.1 based on the previous comment, but it did not fix the issue.

Unfortunately, I only encounter this issue when running some automated tests in a docker container (CentOS 7.6.1810). Things run noticeably slower in the container vs locally (MacOS 10.14.6) so maybe it's timing related as mentioned above. In all cases, the database is running in a separate container (PostgreSQL 11.5 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5), 64-bit).

If it's at all helpful, here's the test code that fails:

let errorEncountered = false;
let results;
try {
    results = await runQuery('SELECT * FROM nonexistant_table');
} catch (err) {
    errorEncountered = true;
    expect(err).to.exist;
    expect(err.message).to.equal('relation "nonexistant_table" does not exist');
}

expect(errorEncountered).to.be.true;

// Reaches here
results = await runQuery('SELECT * FROM good_table WHERE id >= 18 ORDER BY id DESC;');
// Does not reach here

expect(results).to.have.lengthOf(4);
expect(results[2].id).to.equal(19);

runQuery() sends the query to the server via a web socket request and receives the data in chunks. The function resolves when the query has completed.

Here's a much simplified version of my server code:

function executeQuery(query) {
    return new Promise((resolve, reject) => {
        connection.task(async tx => {
            await tx.none('SET <custom_config_key>=<custom_config_value>');

            return tx.stream(queryStream, function (stream) {
                stream.pipe(outputStream);
                
                stream.on('error', err => {
                    outputStream.emit('error', err);
                });

                // Resolve now that the stream has been initiated.
                resolve();
            });
        }).catch(err => {
            reject(err);
        });
    });
}

webSocketRequestHandler(query) {
    const outputStream = new PassThrough({ objectMode: true });

    // Add some stream listeners

    executeQuery(query).then(() => {
        // Send data back to the client in chunks as data comes through the stream
    });
}

The failure happens reliably every time I run the tests, so if there's some places I can add log statements to better track down this problem, I am happy to assist.

After reading this comment and some more experimentation, I seem to have gotten around this problem by making sure the stream is closed before releasing the connection back to the pool.

function executeQuery(query) {
    return new Promise((resolve, reject) => {
        connection.task(async tx => {
            await tx.none('SET <custom_config_key>=<custom_config_value>');
    
            return new Promise((connResolve, connReject) => {
                return tx.stream(queryStream, function (stream) {
                    stream.on('close', () => {
                        // Make sure the stream is closed before releasing the connection back to the connection pool
                        connResolve();
                    });
                    stream.on('error', err => {
                        outputStream.emit('error', err);
                    });
                    stream.pipe(outputStream);

                    // Resolve now that the stream has been initiated.
                    resolve();
                });
            });
        }).catch(err => {
            reject(err);
        });
    });
}

I'm not sure where the right place to make the change would be, but it seems like maybe this safeguard could be added to one of the involved libraries (pg-pool or pg-promise?) so a close listener wouldn't be necessary externally...?

Also, I feel like it's worth mentioning that I initially got around this error by commenting out this line in pg-cursor/index.js. Probably not the best idea to do that, but it helped me figure things out.

For those of you catching this with statement timeouts: I was able to reproduce this error consistently when statement_timeout and query_timeout were set to the same value. Increasing query_timeout relative to statement_timeout seems to improve the frequency at which we see this error

I have a PR up for this: #2367. The fix feels dirty to me, but I think what's happening here might be a race condition within postgres itself we're working around.

pvatterott · 2020-10-08T17:22:40Z

FYI @brianc we did see this on postgres 12.3, not 9.x

brianc · 2020-10-08T18:41:57Z

@pvatterott that's good to know, but a bummer as my hunch was around a race condition in older versions of postgres. I've been going back and forth w/ some postgres maintainers & think this might fix it. I can confirm it fixes in 9.x & 10.x of postgres, it might fix it for 12.3 of postgres as well. The change involves pipelining the sync command in with the other extended query commands all at once. It also improves my benchmarks by up to 10% in some cases, which is a nice side effect.

@pckilgore my pleasure! Let me know if it still happens...was quite a monster to track down but @timotm is the real hero here. Steps to reproduce & deep analysis helped me know where to focus. I regret it took me so long to circle back to this issue.

Hello,
I am still running this issue randomly when I do a qs.destroy();
I posted a full example of the situation here : https://stackoverflow.com/questions/61323787/pg-promise-cancel-a-query-initiated-with-pg-query-stream
While I posted this 10 months ago, I still have this issue with the latest lib.
I am facing this under PostgreSQL 12. Same error occured on PostgreSQL 10.
The main issue is that I can't even find a workaround or catch the error, it crash the whole app.
