| Kinnison | It will if it's a login shell | 08:31 |
| straycat | Right of course, the symlink hack doesn't work because sh is itself a link to busybox I was trying to fix that by defining bash as an alias to busybox sh | 08:34 |
| Kinnison | aah yeah | 08:34 |
| Kinnison | you actually need | 08:34 |
| Kinnison | cat > /bin/bash | 08:35 |
| Kinnison | #!/bin/sh | 08:35 |
| Kinnison | erm | 08:35 |
| Kinnison | no | 08:35 |
| Kinnison | one sec | 08:35 |
| straycat | no | 08:35 |
| Kinnison | /tools/bin/bash | 08:35 |
| Kinnison | #!/tools/bin/sh | 08:35 |
| Kinnison | exec /tools/bin/sh "$@" | 08:35 |
| Kinnison | or something like that | 08:35 |
| Kinnison | I'm pre-caffeination so I could be very wrong | 08:35 |
| franred | for gerrit I've removed sh directly and create a link to bash ln -sfn bash /bin/sh and works | 08:36 |
| straycat | yes that's what I tried, but then that won't work for -c 'script' because you lose the quoting | 08:36 |
| straycat | but I have a work around in mind | 08:37 |
| Kinnison | franred: you mean gerrit is full of #!/bin/sh which assumes sh is bash? | 08:38 |
| Kinnison | straycat: "$@" should work perfectly | 08:38 |
| franred | Kinnison, let me check, I will tell you later | 08:38 |
| pedroalvarez | I accidetally joined the #!/bin/sh channel doing a random click in this conversation | 08:39 |

| petefoth | How do you click using a CLI? | 08:40 |
| straycat | Kinnison, Perhaps I misunderstand "$@" then, I thought it was a space separated list of the paramters' words | 08:40 |
| straycat | petefoth, with gpm | 08:40 |
| Kinnison | @ Expands to the positional parameters, starting from one. When the expansion occurs within double-quotes, each positional parameter expands as a | 08:41 |
| Kinnison | separate argument. If there are no positional parameters, the expansion of @ generates zero arguments, even when @ is double-quoted. What this | 08:41 |
| *** ssam2 [~ssam2@82-70-136-246.dsl.in-addr.zen.co.uk] has joined #baserock | 08:41 | |
| Kinnison | basically means, for example, is if $1 is “abc” and $2 is “def ghi”, then "$@" expands to the two arguments: | 08:41 |
| Kinnison | "abc" "def ghi" | 08:41 |
| straycat | so foo -c "which ls" would expand to "-c" "which" "ls" ... which won't work | 08:42 |
| petefoth | straycat: ta! Now to find an equivalent for iTerm on Mac OS X | 08:42 |
| ssam2 | straycat: surely that'd expand to "-c" "which ls" ? | 08:43 |
| Kinnison | straycat: I'm very confused as to what you're on about, ssam2's expansion is correct | 08:43 |
| richard_maw | I think he's putting the -c in the #! line | 09:06 |
| richard_maw | which doesn't work because Linux's #! parser is rather primitive | 09:06 |
| Kinnison | Buh | 09:06 |
| Kinnison | Why would you do that? | 09:06 |
| richard_maw | there's a bunch of clever hacks I'd be doing with that if it were possible | 09:07 |
| ssam2 | are there Debian users who have Ruby installed here ? | 09:08 |
| Kinnison | depressingly I do have it on my system | 09:09 |
| ssam2 | if so, could you run 'gem env' and tell me what it lists as GEM PATHS ? | 09:09 |
| Kinnison | - GEM PATHS: | 09:09 |
| Kinnison | - /var/lib/gems/1.9.1 | 09:09 |
| Kinnison | - /home/danielsilverstone/.gem/ruby/1.9.1 | 09:09 |
| Kinnison | - /usr/share/rubygems-integration/1.9.1 | 09:09 |
| richard_maw | I used to until I rebuilt my vim so I didn't have to link against it | 09:09 |
| ssam2 | just noticed that in Baserock we put Gems in /usr/lib/ruby/$VERSION/gems | 09:09 |
| ssam2 | but on Fedora they're in /usr/share/gems | 09:09 |
| ssam2 | and it seems on Debian they're in /var/lib/gems/$VERSION | 09:09 |
| richard_maw | or /usr/share/rubygems-integration/$VERSION | 09:10 |
| ssam2 | I think that's a Kinnison-addition :) | 09:10 |
| Kinnison | nup | 09:10 |
| ssam2 | ah, OK | 09:10 |
| ssam2 | anyone have any views on where they should go in Baserock? I want to remove the $VERSION from our path, because I don't think we'll often be wanting two Ruby versions in a Baserock system, and having $VERSION in there means the import tool has to know what version of Ruby a particular Baserock system uses | 09:10 |
| ssam2 | I'm thinking /usr/lib/ruby/gems as the default GEM PATH | 09:11 |
| Kinnison | I thought some of our QT systems explicitly had ruby1.8 *and* ruby1.9 | 09:11 |
| ssam2 | oh :( | 09:11 |
| Kinnison | because of awkward build-deps | 09:11 |
| ssam2 | maybe the ugliness must remain, then | 09:11 |
| ssam2 | oh well, at least that's less work for me now :) | 09:12 |
| ssam2 | even if it probably creates more work for other people in the future, when they want to change the version of Ruby in use in their system | 09:12 |
| ssam2 | hmm, actually there's probably a clever way to do this in the configure-commands | 09:12 |
| ssam2 | yeah, `gem environment home` is way forward. As Kinnison's original notes from June do tell me :) | 09:14 |
| ssam2 | +the way forward | 09:14 |
| Kinnison | Ruhroh | 09:18 |

| Kinnison | Anyone know how hard/easy it is to set up a one-node distbuild controller+worker+initiator for doing development of distbuild? | 10:43 |
| SotK | on your laptop or some vmhost? | 10:45 |
| SotK | or on a devboard of some kind? | 10:45 |
| radiofree | Kinnison: pretty easy | 10:45 |
| radiofree | i used to use a jetson for that | 10:45 |
| radiofree | this http://wiki.baserock.org/guides/jetson_distbuild_cluster/ essential documents flashing a board with a devel image | 10:46 |
| SotK | its easy to do it in on a VM host, I have never done it on a devboard though | 10:46 |
| radiofree | building the distbuild image, and then deploying it | 10:46 |
| radiofree | of course the deployment would only need build-controller, with itself as a worker | 10:47 |
| Kinnison | Cool | 10:47 |
| * Kinnison is pondering if he can improve the feedback for long builds | 10:47 | |
| Kinnison | Perhaps I'll wait for richard_maw's rework branch to land first though | 10:48 |
| radiofree | the flashing step in that still uses the old method however | 10:49 |
| Kinnison | I'm likely to do it as an x86_64 container on my laptop for ease of portability | 10:49 |
| radiofree | if you had a jetson flashed using the baserock-jetson-flash.sh (i.e using u-boot and btrfs) to flash the devel image (as documented in the other jetson guide), could one deploy the upgrade to a distbuild controller/node to itself? | 10:50 |
| Kinnison | I don't know what state our self-upgrade stuff is in, but in theory -- yes | 10:51 |
| franred | could someone spot something about why chown can not work in this morphology? http://fpaste.org/132723/32848141/ | 10:54 |
| franred | everything works but the owner of the gerrit folder is root so I gerrit2 does not have permissions to run its initialization script :/ | 10:55 |
| Kinnison | busybox's chown doesn't do foo:bar IIRC | 10:55 |
| Kinnison | do a chown and chgrp separately | 10:55 |
| ssam2 | Usage: chown [-RhLHPcvf]... OWNER[<.|:>[GROUP]] FILE... | 10:55 |
| franred | Kinnison, I did manually | 10:55 |
| ssam2 | seems like it does | 10:55 |
| Kinnison | hmm | 10:55 |
| Kinnison | Put that set of behaviour into a script you install and then in the integration commands do sudo -u gerrit2 /path/to/script | 10:56 |
| Kinnison | then you're not fiddling partly as root | 10:56 |
| franred | Kinnison, that is what Im trying to avoid - I mean, create the script | 10:57 |
| radiofree | franred: does the owner where's the config script /home/gerrit2/gerrit/.gerrit_controller? | 10:57 |
| radiofree | does the gerrit2 command create the gerrit/.gerrit_controller folder? | 10:58 |
| franred | radiofree, yes it does | 10:58 |
| Kinnison | franred: why are you trying to avoid having it done more neatly? | 10:59 |
| radiofree | it's creating it as root then? | 10:59 |
| franred | radiofree, yes, it is creating it as root, not sure why | 11:00 |
| radiofree | sudo -u gerrit2 java -jar /home/gerrit2/gerrit/gerrit-2.9.war init --batch .... -d /home/gerrit2/gerrit/.gerrit_controller --no-auto-start | 11:00 |
| franred | ummm, yeah | 11:00 |
| * pedroalvarez manages to deploy a generic trove to OpenStack and instantiate it with a simple cloud-init script | 11:01 | |
| franred | radiofree, but that does not explain why gerrit folder is owned by root I though | 11:01 |
| radiofree | Yeah.. And you're using -u... | 11:01 |
| radiofree | No idea sorry | 11:02 |
| pedroalvarez | franred: sudo -u gerrit2 mkdir /home/gerrit2/gerrit | 11:02 |
| franred | Kinnison, I was told to not use one shot services and use system-integration commands | 11:08 |
| franred | so create a script and run it in system-integration only will move what I've done to this part | 11:09 |
| franred | so it is unlike | 11:09 |

| straycat | Sure, why? | 16:45 |
| Kinnison | so it gets through | 16:45 |
| straycat | Why do we need to escape the ' | 16:46 |
| Kinnison | straycat: given you asked the question with zero context, I can't possibly comment | 16:47 |
| richard_maw | it turns a string, such as "foo'bar" into 'foo'\''bar' | 16:47 |
| straycat | Isn't it trying to turn "foo'bar" into "'foo'\''bar'" | 16:49 |
| richard_maw | though I think it needs to use `printf '%s\n' "$1"` instead of `echo "$1"`, since echo will interpret escape sequences | 16:49 |
| straycat | Ahh | 16:50 |
| richard_maw | it's one of the easiest ways of doing shell escapes, since you only need to escape the ' character, but it also produces the ugliest escaped string | 16:56 |
| richard_maw | especially if you have multiple levels of escaping involved | 16:56 |
| straycat | What's confusing me is that when I run this I get "'foo'''bar'" | 16:57 |
| richard_maw | where are you running it? | 16:58 |
| straycat | In a bash shell | 16:58 |
| richard_maw | hm, it needs to be \\\\, rather than \\ then | 16:59 |
| richard_maw | because both the shell and sed are consuming them | 17:00 |
| straycat | benbrown1 suggested \\\ which seems to work | 17:00 |
