“Unknown system error -75” nodejs fs.stat large files #19455

filly82 · 2018-03-19T20:06:18Z

I don't know what happened on my system (raspberry pi, armhf, latest nodejs version) but since a few days I cannot fs.stat a file that is larger than 2gb

I am always getting the following error

`
fs.js:972
binding.stat(pathModule.toNamespacedPath(path));
^

Error: Unknown system error -75: Unknown system error -75, stat 'myfile'

I know for sure that it worked a few days ago. it's like I'm suddenly on a 32bit system (or node or whatever).

I thought it was the current nodejs version 9.8.0, but i've tested it with 9.7.1 and 9.7.0 and it's the same.

Does anyone have any idea what is wrong? :(

From stat(2):

EOVERFLOW
pathname or fd refers to a file whose size, inode number, or number of blocks cannot be represented in, respectively, the types off_t, ino_t, or blkcnt_t. This error can occur when,
for example, an application compiled on a 32-bit platform without -D_FILE_OFFSET_BITS=64 calls stat() on a file whose size exceeds (1<<31)-1 bytes.

(not sure about arm, but on x64 Linux EOVERFLOW is 75, so that checks out).

So, yes, this is the most likely cause… it might be a good idea to check whether your node executable is built for 64 bit support? file $(which node) would be a good starting point

filly82 · 2018-03-19T21:30:42Z

that is the output

file $(which node)
/usr/bin/node: ELF 32-bit LSB executable, ARM, EABI5 version 1 (GNU/Linux), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.26, BuildID[sha1]=46883207b843e59d049607d8bdfefb8de2bcf7a9, stripped

i still not get it. it worked fine until it didn't. the only things i am doing on this pi is updating it from time to time (the usual apt-get update/upgrade/dist-upgrade)

addaleax · 2018-03-19T21:36:34Z

@filly82 Did you (intend to) install Node via your package manager or another way? (I think dpkg -S /usr/bin/node would tell you that in the case of apt-get).

In any case, the BuildID from that output matches the one for the official node-v9.8.0-linux-armv7l download from https://nodejs.org/, so somehow that binary made its way from there onto your machine.

filly82 · 2018-03-19T21:45:36Z

i do not really care how to install node. i chose the easiest way back then with the script from deb.nodesource.com

i've also tried the binaries from https://nodejs.org a few minutes ago, the same problem

the only binaries i can execute on my raspberry pi are the armv7 ones. what do you mean with your last sentence that that binaries made their way onto my machine? i think that binaries were always on my machine since they are the only ones which work. and i know for sure that i had not have the problem with large files until a few days ago

addaleax · 2018-03-19T21:51:00Z

the only binaries i can execute on my raspberry pi are the armv7 ones

Those are 32-bit binaries, though. If you have an armv7 machine, you won’t be able to run 64-bit Node binaries, as I understand it. So I’m really not sure how this could have worked in the first place then…

I suppose we could build Node with -D_FILE_OFFSET_BITS=64 to make sure that we support this, though? /cc @bnoordhuis

filly82 · 2018-03-19T22:03:25Z

what i can say for sure is that my node app has been running for a few months and that i always had files bigger than 2gb. i am 100% sure that those files were correctly "stat"-ed until a few days ago. they must have, because I've worked with the results every day for the past few months

i'll try to install an arm64 OS (unfortunately there are no stable distributions for the raspberry pi with 64bit support, i did not really knew that until that problem popped out). that would fix my problem, i think. but i am still wondering how it could work with the current constellation for a few months

bnoordhuis · 2018-03-20T09:18:09Z

I suppose we could build Node with -D_FILE_OFFSET_BITS=64 to make sure that we support this

It is - at least, libuv is, and that's what makes the system call.

@filly82 Can you post the output of strace node -p 'fs.statSync("myfile")'?

@filly82 It failed with ReferenceError: test is not defined. Can you try again and make sure it fails with that -75 errno?

filly82 · 2018-03-20T19:33:45Z

sorry, i am not familiar with strace
when i do
node test.js it fails with -75
but when i do
strace node -p test.js
it does not

am i doing it right? test.js is the test node script with just fs.statSync('myfile')

filly82 · 2018-03-20T19:37:12Z

i tried
strace node test.js and got this

Faulty logic in commit fdf7c2a ("build: split off tests into separate gyp file") accidentally disabled `-D_FILE_OFFSET_BITS=64` on Unices, breaking file operations on files > 2 GB on 32 bits platforms. Fixes: nodejs/node#19455

bnoordhuis · 2018-03-20T20:14:14Z

Thanks, I found the issue. Fix in libuv/libuv#1779.

filly82 · 2018-03-20T20:24:16Z

OK. So the Bug came with a libuv Update onto my system?

bnoordhuis · 2018-03-20T20:26:04Z

In a way. Node.js bundles libuv.

filly82 · 2018-03-20T20:29:39Z

How come a downgrade on node 9.7.1 / 9.7.0 did not work? I am pretty sure that it did work a week ago when i had one of that Versions

filly82 · 2018-03-20T20:30:47Z

But great that you find out Something. Thanks for looking into it
how and when can i get that Bugfix?

bnoordhuis · 2018-03-20T20:34:15Z

The next v9.x release with a bit of luck. Preempting the question of when: probably in a week or so.

If that doesn't work for you, build node from source and apply the patch locally to deps/uv.

filly82 · 2018-03-20T20:38:01Z

Great thanks. Should i Close this then or leave it opened?

bnoordhuis · 2018-03-20T21:10:50Z

It'll auto-close when the libuv PR is merged.

Is it possible to get this fix back-ported to Node 8.X LTS? We are still using node in a 32 bit linux environment that has to deal with files >2GB.

Thanks!

MylesBorins · 2018-10-23T14:45:25Z

/cc @nodejs/libuv we had to stop at 1.19.2 due to incompatible changes in 1.20.0... tbh I can't remember exactly what they are but I think @cjihrig would know.

Would you like to open another issue to track this?

cjihrig · 2018-10-23T15:27:08Z

I think you're referring to #22814 and #21203. Both of those issues are fixed. A regression test for #22814 landed in #23051. #23053 fixed #21203, but it's marked as don't land on v10 and earlier. Now, that might be backportable since it reverts a semver major and the version of libuv can now be updated on those older branches (cc: @addaleax since that is her PR).
