I had some free time this weekend and I've spent some of it trying to learn Go since mlmym seems to be unmaintained and I'd like to try to fix some issues in it. I ran into a stumbling block that took a while to solve and which I had trouble finding relevant search results for. I've got it solved now, but felt like writing this up in case it helps anyone else out.
When running most go commands I tried (e.g. go mod init example/hello or go run hello.go or even something as seemingly innocuous as go doc cmd/compile when a go.mod file exists) the command would hang for a rather long time. In most cases, that was about 20~30 seconds, but in one case -- trying to get it to output the docs about the compile tool -- it took 1 minute and 15 seconds! This was on a relatively fresh Linux Mint install on old, but fairly decent hardware using golang-1.23 (installed from apt).
After the long wait, it would print out go: RLock go.mod: no locks available -- and might or might not do anything else depending on the command. (I did get documentation out after the 1min+ wait, for example.)
Now, there's no good reason I could think of why printing out some documentation or running Hello World should take that long, so I tried looking at what was going on with strace --relative-timestamps go run hello.go > trace.txt 2>&1 and found this in the output file:
0.000045 flock(3, LOCK_SH) = -1 ENOLCK (No locks available)
25.059805 clock_gettime(CLOCK_MONOTONIC, {tv_sec=3691, tv_nsec=443533733}) = 0
It was hanging on flock for 25 seconds (before calling clock_gettime).
The directory I was running in was from an NFS mount which was using NFSv3 unintentionally. File locking does not work on NFSv3 out of the box. In my case, changing the configuration to allow it to use NFSv4 was the fix I needed. After making the change a clean Hello World build takes ~5 seconds -- and a fraction of a second with cache.
After solving it, I've found out that there are some issues related to this open already (with a different error message -- cmd/go: "RLock …: Function not implemented") and a reply on an old StackOverflow about a similiar issue from one of the developers encouraging people to file a new issue if they can't find a workaround (like I did). For future reference, those links are:
They sell farmed, ground venison in one of the grocery stores I go to. It's imported from New Zealand, IIRC. I got a couple packs of it once. The stuff I got, at least, had a more iron-forward flavor than what I'm used to from beef and was very lean -- which made it less satisfying than ground beef or lamb for most of the dishes I use ground meat for. It tasted like beef that, if I paid attention, was kind of off, but otherwise wasn't very notable. Edible, but not something I've felt much inclination to seek out again. I'd be willing to get it again if it was cheaper or if I need to change my diet to be lower in fat, but otherwise I'd rather just have beef or lamb. I have not tried it as a steak though, and I haven't had wild caught as far as I can recall.
