epochserver.so - segfault #656

Closed xai1 closed 7 years ago

xai1 commented 7 years ago

Updated one of my servers to the latest version. After changing the epochserver.so the server crashes when the game starts. Already checked the issue #644 and tried the epochserver.so provided there but without luck.

RPT error before crash. 19:25:50 "Epoch: Starting ArmA3 Epoch Server, Version 0.4.0.0" terminate called after throwing an instance of 'char const*'

vbawol commented 7 years ago

Hello @xai1

This is the only occurrence of 'char const*' I can find in our code: https://github.com/EpochModTeam/EpochServer/blob/master/src/external/ConfigFile.cpp#L4

Seems like this is likely related to the config file and from a quick first look at the code it maybe that we are not accounting for unix line endings properly. You can test this by converting your epochserver.ini to use windows line endings (unix2dos) and try starting the server again.

xai1 commented 7 years ago

Hi @vbawol Thanks for you fast feedback. Converting the config didn't help. I am still getting the same error.

vbawol commented 7 years ago

I will see if I can reproduce this on my dev server this week. @denisio, @Fank can either of you guys offer any advice here?

xai1 commented 7 years ago

@vbawol Thx. If you need any more input from my side, let me know it.

do you need the epochserver.ini attached? or is it only about the content?

denisio commented 7 years ago

Try to download http://epocher.ru/epochhive.tgz and unpack to @epochhive/

Check ldd epochserver.so

I think that static build on Ubuntu?? is not compatible with Debian (libc6 versions).

vbawol commented 7 years ago

Thought, I built it on Debian 8.6...? but now that I check my dev server: lsb_release -da

Distributor ID: Debian Description: Debian GNU/Linux 7.11 (wheezy) Release: 7.11

@denisio, What version did you build against was it Debian 6.8 or 8.6?

Thanks for looking into it @denisio!

I do "apt-get upgrade" and "apt-get dist-upgrade". $ cat /etc/debian_version 8.6

Why is "DLL mismatch" ?? $ git clone https://github.com/EpochModTeam/EpochServer.git

xai1 commented 7 years ago

@denisio I copied the files you provided earlier again to the server and it seems to be ok now. Sry seems like I did something wrong. Thank you very much for your help!

vbawol commented 7 years ago

Turns out it was Ubuntu, So I got a new dev server running Debian 8.6 and recompiled epochserver.so @xai1 can you test this version if you have the time: https://github.com/EpochModTeam/Epoch/raw/9d54517986140a263ceddc2e3cbba7127c1ed2b5/Server_Install_Pack/%40epochhive/epochserver.so

@denisio do you foresee any issues with statically linking pcre and hiredis?

denisio commented 7 years ago

I have not tested this but the libc6 downgrade need lowest version (Debian build for example).

xai1 commented 7 years ago

@vbawol still getting the same issue. Just to make sure, I only need the epochserver.so in @epochhive, right?

vbawol commented 7 years ago

@xai1 yes that was the goal. However, I think I will go back to compiling with shared libs on Linux as I noticed that libpthread.so.0 was not linked and is likely a dependency of libhiredis or libpcre.

Rebuilt with -lhiredis -lpcre https://github.com/EpochModTeam/Epoch/raw/57a5ec6edf8950daff22e604b114bbb82cfb93bd/Server_Install_Pack/%40epochhive/epochserver.so

If it does not work, try installing: apt-get install libhiredis-dev libpcre3-dev

Otherwise, I guess we will need to also ship the libhiredis.so libpcre.so.3 files as we did before?

xai1 commented 7 years ago

@vbawol I am not able to test it before Friday, sry. Will let you know as soon as I have been able to test it

vbawol commented 7 years ago

Not sure why it is proving to be so difficult for me to setup a new arma 3 1.64 linux server. Both Debian 8.6 and Ubuntu 16.04 are setup the same way: https://community.bistudio.com/wiki/Arma_3_Dedicated_Server#Instructions_.28Linux_o.2Fs.29

xai1 commented 7 years ago

@vbawol sry for my late reply. Haven't been able to test it earlier.

Intsalled: libhiredis-dev libpcre3-dev

ldd epochserver.so linux-gate.so.1 (0xe3d43000) libhiredis.so.0.10 => not found libpcre.so.3 => not found libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xe3b61000) libm.so.6 => /lib/i386-linux-gnu/i686/cmov/libm.so.6 (0xe3b1b000) libgcc_s.so.1 => /lib/i386-linux-gnu/libgcc_s.so.1 (0xe3afe000) libc.so.6 => /lib/i386-linux-gnu/i686/cmov/libc.so.6 (0xe3951000) /lib/ld-linux.so.2 (0xe3d44000)

I get the following error: 18:03:07 "Epoch: Server DLL mismatch! Current: Needed: 0.5.1.8"

I guess this happend because it is missing libhiredis.so.0.10 and libpcre.so.3?

vbawol commented 7 years ago

yes @xai1 looks like it, as of this comment I have readded these two files: https://github.com/EpochModTeam/Epoch/commit/7913ee0ea78782184ca24821d6f64a4ba385c800

I will work more on the static epochserver.so build again after I get my dev environment sorted and running. Thanks for the help testing!

xai1 commented 7 years ago

@vbawol let me know as soon as I can help you with testing.

vbawol commented 7 years ago

@xai1 are you still running a Linux Epoch server? If so I have some new extensions to test out. These are built using holy build box and should be compatible with a wider range of distros.
