 |
|
After updating net-dns/c-ares from 1.21.0 to 1.22.0 today, any curl command hang indefinitely. For example:
Using --verbose doesn't display anything. I'm only seeing the curl process using a noticeable amount of my CPU.
I tried to re-emerge net-misc/curl and rebooting my system, but it doesn't make any difference.
| Code: | $ eix -cI net-misc/curl
[I] net-misc/curl (8.4.0@11/15/2023): A Client that groks URLs
|
any | Code: | $ git fetch
$ git pull |
command is also hanging as I'm using the curl USE flag for dev-vcs/git.
Downgrading to net-dns/c-ares 1.21.0 immediately solves the issue without any further intervention.
Just wondering if someone's also having the same issue, it might be worth opening a bug in this case.

I'm using c-ares-1.22.0 and curl-8.4.0[adns] and not having issues with curl myself (that command works, git[curl] is same as usual too).
Are you using any uncommon C(XX)FLAGS? Could potentially be triggering undefined behaviour issues in that particular version. Don't have a whole lot of ideas for possible causes (also don't see anything that sounds related on c-ares nor curl bug tracker so far, albeit 1.22.0 release is pretty recent). |

No, I'm not:
| Code: | # /etc/portage/make.conf
CFLAGS="${COMMON_FLAGS}"
CXXFLAGS="${COMMON_FLAGS}"

I checked both GitHub repositories too prior to creating this thread but couldn't find anything relevant either. I'll stick with 1.21.0 for now.
I'll see if that also occurs on my Arch Linux install, 1.22.0 hasn't made it to the Arch repos yet, even in [extra-testing]. |

| For someone who can reproduce this, identifying in what function c-ares is spinning would be a useful next step. Debug symbols will likely be required for this to be meaningful. |

Fixed upstream with this commit.
I applied the patch and rebuilt net-dns/c-ares-1.22.0, all good now. |
