I have experienced many instances of Shepherd hanging through my use of Guix, though I don't have a clear record of when it first happened. These days I have seen a few reports on the subject. With a quick search of recent bug reports, I can't find any related, only to find this thread [1] on help-guix. So I'll start a bug report here, but I don't know how to debug Shepherd and I haven't found a way to reproduce it stably. I'm not sure if Shepherd hangs at usual, but most of the time I find it already hanging is when doing a reconfiguration. The reconfiguration becomes unresponsive and it won't accept a ^C, herd actions also hang. This usually happens with home reconfiguration, but I can remember once with system reconfiguration when adding and deleting some services in the configuration file. I'm not sure how Shepherd hangs either, because in the latter case (system one) I can still see logs indicating that it's trying to respawn a process I killed manually, even though that's just a output and no processes are actually spawned. And as shown in [1], there are also cases where Shepherd hangs at some point in the halting process, usually after syslogd has been terminated but before term-tty*. (The termination message indicates that Shepherd is still functional, and no logs after that point shows that that's a real action, but because of this I can't know anything happened further either. After that I'm still able to switch ttys so I assume term-tty* are alive.) Although I don't know how they are related, I have linked my configurations below: Thanks [1]: (public-inbox mirror on yhetil.org) From debbugs-submit-bounces@debbugs.gnu.org Sun Aug 13 11:28:11 2023 Received: (at 65178) by debbugs.gnu.org; 13 Aug 2023 15:28:11 +0000 Received: from localhost ([127.0.0.1]:60107 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1qVD0k-0004Xn-SE for submit@debbugs.gnu.org; Sun, 13 Aug 2023 11:28:11 -0400 Received: from mail.boiledscript.com ([144.168.59.46]:50456) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1qVD0i-0004Xe-QO for 65178@debbugs.gnu.org; Sun, 13 Aug 2023 11:28:09 -0400 Date: Sun, 13 Aug 2023 23:25:59 +0800 DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=ultrarare.space; s=dkim; t=1691940476; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: in-reply-to:in-reply-to:references:references; bh=rUv/a1fQSAGx3Ko5Jj5HXpP6oDUnvBhOBMFHI6Ni8Kk=; b=M+nmFILCwdIXpQyil59s7ct46LiJ//gWhSQWmWlRks81+2MqUpazUshM/U4g6/mFTjTJM7 sxOsz/J7IaFQ3BXVnvJAJJWTfBUevG1v5JwPCvbSW7js1BEMXkhmghKW/LHY/4KvIN9cLe h0x6QqfywRhau6meRPd6iUZbdd5zEjqxTlx3iADVM93ZHTO0Ts2YetHlEPuQLh7dDiF8OA vLgWKpSZenRZHbwye9Wwo9R23H99QxkqfhQZiXiGzd4KTe/ml8uCBE804W0R0dRO2YDVJT 7+DdnXoP39/ByKwKfc+xwRKmpTTxyHQyhhp/SdX2ZRZGDxMe1g0+wNAf4pZGsA== Authentication-Results: mail.boiledscript.com; auth=pass smtp.mailfrom=hako@ultrarare.space Message-ID: <87leefx8u0.wl-hako@ultrarare.space> From: Hilton Chain To: 65178@debbugs.gnu.org Subject: Re: Shepherd hangs (was: Getting Guix to shutdown my laptop properly with Sway and no DE) In-Reply-To: <87bkfg1j7b.wl-hako@ultrarare.space> References: <87bkfg1j7b.wl-hako@ultrarare.space> MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII X-Spamd-Bar: / X-Spam-Score: 0.0 (/) X-Debbugs-Envelope-To: 65178 X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -1.0 (-) On Wed, 09 Aug 2023 20:41:44 +0800, Hilton Chain wrote: > I'm not sure if Shepherd hangs at usual, but most of the time I find > it already hanging is when doing a reconfiguration.

Same symptoms here again. For context: this time I was trying to deploy some OCI/Docker containers us= ing Guix' `oci-container-service-type', specifically a Shepherd service called "conduit". My code is here: https://cgit.twilken.net/dotfiles/log/?h=3Dmatrix-containers (Specifically, commits bf94f7872a1df293bd904bbd2c1ef7229f4f98a8 and c87dcdae79c6266ac3dac70af08fbef5eb21629b.) This is with Guix commit 1b2505217cf222d98cc960b8510660976a01cfa1. I first ran "guix system reconfigure -L . tw/system/lud.scm" with commit bf94f7872a1df293bd904bbd2c1ef7229f4f98a8, which had a bug (an env var was wrong, so the container failed to start). This worked as expected in that Shepherd tried to start the service, which failed, so Shepherd disabled it. Then, I fixed the env var and re-ran "guix system reconfigure -L . tw/system/lud.scm" with commit c87dcdae79c6266ac3dac70af08fbef5eb21629b. Shepherd loaded the new "conduit" service fine, as far as I can tell, but didn't restart it because it was still disabled. I then enabled and started the service manually. Enabling worked fine, but = on start, I got no terminal output from Shepherd, and it hung. I still had an error in my setup (directory permissions were wrong), and I = got a message in /var/log/messages to that effect: --8<---------------cut here---------------start------------->8--- Dec 14 21:33:50 localhost shepherd[1]: Service conduit is currently disable= d.=20 Dec 14 21:34:04 localhost shepherd[1]: Enabled service conduit.=20 Dec 14 21:34:07 localhost shepherd[1]: Starting service user-homes...=20 Dec 14 21:34:07 localhost shepherd[1]: Service user-homes has been started.= =20 Dec 14 21:34:07 localhost shepherd[1]: Service user-homes started.=20 Dec 14 21:34:07 localhost shepherd[1]: Service user-homes running with valu= e #t.=20 Dec 14 21:34:07 localhost shepherd[1]: Starting service conduit...=20 Dec 14 21:34:07 localhost shepherd[1]: Service conduit has been started.=20 Dec 14 21:34:07 localhost shepherd[1]: Service conduit started.=20 Dec 14 21:34:07 localhost shepherd[1]: Service conduit running with value 1= 3226.=20 Dec 14 21:34:07 localhost shepherd[1]: [docker] conduit: [...] "IO error: W= hile open a file for appending: /var/lib/matrix-conduit/LOG: Permission den= ied" --8<---------------cut here---------------end--------------->8--- ...showing that Shepherd had at least tried to start the new container. The container is not running, though (due to the error shown above), and nothin= g with PID 13226 is running. The "herd start conduit" command did not return, and ^C-ing it did not help= . Afterwards, every "herd" command also hung without any output. Here are the last four lines of the output of "sudo strace -s1000 herd stat= us" on such a hung machine: --8<---------------cut here---------------start------------->8--- connect(10, {sa_family=3DAF_UNIX, sun_path=3D"/var/run/shepherd/socket"}, 2= 6) =3D 0 getcwd("/home/timo", 100) =3D 11 write(10, "(shepherd-command (version 0) (action status) (service root) (ar= guments ()) (directory \"/home/timo\"))", 101) =3D 101 read(10, --8<---------------cut here---------------end--------------->8--- The "read(10, " call never completes. At least in this case, Shepherd still seems to be processing inbound inet connections, so I can open new SSH connections to the machine. Attaching to PID 1 with strace shows it is stuck in "epoll_wait(13, " (unsurprisingly, fd 13 points to "anon_inode:[eventpoll]").
