Adventures in tinderbox 2

If you stumbled into this post first you may want to have a look over this previous post as we are building upon steps covered there.

So far we have got our world binaries built and these are the foundation of the environments we setup for testing our port builds. From here we create a tinderbox build. Within tinderbox a build refers to a combination of world binaries (the tinderbox jails we setup before) and a version of the ports files. It is probably a rare case but it would appear that you could setup a build using say netbsd pkgsrc system or similar, the most likely alternative to the official ports system would be an internal development branch of the ports source.

The first step is to setup the ports files to be used. A cvs checkout is shown in the docs and you could adjust the svn usage from yesterday if you have your own local svn repo (official ports are still in cvs at this point). The examples in the docs show a source checkout that is unique to your tinderbox setup. I think using the system installed ports will be enough for what I want and will bypass the confusion of three copies of the ports files. Personally I use portsnap to update my system ports tree and create or update a port there to test and develop it. Then I have a copy within my home folder that is an svn checkout from my redports account that I transfer changes to that I want to keep, and commit as desired from there. While my personal folder is just the ports I make changes to, I don't want a third copy just for test builds, so what I will use here is a user defined update method that will run portsnap anytime I want to update the ports tree. We have two options here, 1. create a portsTree with no update method leaving us to run portsnap manually as desired. 2. create a portsTree with a user update method. The first option is straight forward and acceptable for most but I want to look at option 2 here.

Reading the docs you may jump straight in and use a command like cd /usr/local/tinderbox/scripts ./tc createPortsTree -p FreeBSD -u USER -m /usr/ports and get errors and no ports tree setup. The docs don't help here so I went digging through the scripts and found the answer. When you create a portstree with a user defined update method it looks for the update script when it is first setup. The solution is simple. If we are creating a portstree called FreeBSD then we create a file in tinderbox/portstrees/FreeBSD and call it and for this example I want it to run portsnap so I use the following contents - #!/bin/sh portsnap fetch update Then run the createPortsTree command with the -u USER option. Simple and a good basis of any custom update you want to setup. You could even use this to run portsnap and then merge files from your personal ports repo automatically. This setup script is run with the command ./tc updatePortsTree

You may also want to share your local distfiles with tinderbox. Pretty easy and the one setup is shared across all portstree configs -

cd /usr/local/tinderbox/scripts ./tc configDistfile -c /usr/ports/distfiles

Now that we have our jails and portsTree setup it is time for the build. Remember a tinderbox build is a combination of a specific jail and portsTree and is straight forward -

cd /usr/local/tinderbox/scripts ./tc createBuild -b 10-CURRENT-clang -j 10-CURRENT -p FreeBSD -d "10-CURRENT building with clang"

The name I used there may raise a few questions but first lets consider what variations of builds we want to use.

The aim of using tinderbox is to test building under a variety of conditions, in this case primarily different system versions. To that end we started by creating 2 jails with different versions of world binaries, you may have extended that number and I encourage you to do so but I use two in these examples. From FreeBSD 9.0 we are moving away from a  dependency on gcc as the main compiler and now include clang within the base system. Being in the early transition of this is a bit awkward as not all ports build with the old gcc v4.2 that is included with base and not all ports build with clang either. Well ports changes need to be tested with each compiler so we may get a full ports build happening on any system install. One option we have is to specify what version of gcc is used to build our port. Easy till we get linking issues with something like boost installed with gcc42 and not linking with a gcc46 built port (that is my early guess and may not be the location of a solution). So anyway I am suggesting that a number of builds are setup to test building with clang as well as gcc. This will only apply to 9.0 and higher, 8.3 has just entered beta1 and doesn't appear to include clang. The other question you may have is that I only put clang in the name, how does it know to build with clang? It doesn't yet - that comes in a minute.

Well using the two jails we built yesterday lets setup the builds -

cd /usr/local/tinderbox/scripts ./tc createBuild -b 10-CURRENT-clang -j 10-CURRENT -p FreeBSD -d "10-CURRENT building with clang" ./tc createBuild -b 10-CURRENT-gcc -j 10-CURRENT -p FreeBSD -d "10-CURRENT building with gcc" ./tc createBuild -b 9-STABLE-clang -j 9-STABLE -p FreeBSD -d "9-STABLE building with clang" ./tc createBuild -b 9-STABLE-gcc -j 9-STABLE -p FreeBSD -d "9-STABLE building with gcc"

Now we have four builds setup to test our ports in. As I suggested before you should also consider having at least an 8-STABLE jail setup and maybe even a 7-STABLE one as well if not more. As clang is not included in 7 or 8 there is no need to setup two builds for each, I would still use gcc in the build name though.

At this point you will find a few directories have been created. The first you will probably see is tinderbox/{BUILDNAME} so if your following along you will have four there corresponding to each build you setup. The next ones are inside tinderbox/builds and have the same names as the four we just looked at. The dirs inside builds contain a Makefile with all the package  dependencies and although you may think make.0 and make.1 are makefiles they are in fact logs containing the log of the last compile done, each port compile is run in two phases, and a more than likely empty duds file. The top level dirs are where all the work is done. For each port you make, tinderbox will extract the tarball found in the corresponding jail build and mount the various points needed for portstrees/distfiles/devfs/procfs. From that you can work out that each build starts up in a unique environment (it uses chroot) completely isolated for your test make. Each environment is cleaned up after each test make and the log files will include files left behind if you get your pkg-plist incorrect.

Now to configuring the compiler to use. When you first test making your port and look at a log file you may notice that the timestamp at the start is all wrong. That will be a wrong timezone setting and gets us close to the compiler settings. First lets set the timezone, so edit the file tinderbox/scripts/etc/env/GLOBAL and add the following line (adjusted to match your timezone of course)

export TZ=Australia/Adelaide

You can see that it uses a bash style environment setting. Within the same folder we want to create a config file for each build we setup using the name build.{BUILDNAME} and have it contain the CC options that we wish to use. Before you go thinking about copying all your /etc/make.conf settings consider the purpose of this - testing against a minimum system config to ensure your port is as compatible as possible. Those with a custom edited make.conf need to handle their own port build conflicts with the options they want to use. So here all we want to do is set the compiler to use. To make this easy let's make a script, I will put this inside tinderbox/scripts and lets call it

#!/bin/sh cd /usr/local/tinderbox/scripts/etc/env for BNAME in `ls ../../../builds | grep clang` do if [ ! -e build.$BNAME ] then cat > build.$BNAME <<CCOPTIONS export CC=clang export CXX=clang++ export CPP=clang-cpp CCOPTIONS fi done for BNAME in `ls ../../../builds | grep gcc` do if [ ! -e build.$BNAME ] then cat > build.$BNAME <<CCOPTIONS export CC=gcc export CXX=g++ export CPP=cpp CCOPTIONS fi done

Pretty straight forward if you know some shell scripting, if it's a bit beyond what you know it simply gets a list of dirs from within builds and outputs three lines to a corresponding config file for each one. The script won't touch files that already exist, so delete them if you want a clean slate or adjust if you want to add to existing files. The first loop uses grep to get clang named builds the second gcc. Is it overkill specifying gcc for the gcc builds - yep - but it keeps things consistent and also gets the CC setting output to the log file to remove any confusion when looking over them later, or more to the point when you get someone else to look over them for some help.

Now your all setup to use tinderbox to test your ports building. While the docs say you can do an adhoc build with just the tinderbuild command I find that not to be the case, the two command you use are

cd /usr/local/tinderbox/scripts ./tc addPort -b 10-CURRENT-clang -d graphics/blender ./tc tinderbuild -nullfs -b 10-CURRENT-clang graphics/blender

The first time you build a port it may take a while - it will build each  dependency needed, basically running make package-recursive for your port. Next time it will just pkg_add each dependancy and build the port you ask it to. The -nullfs option is needed if you setup the nullfs mount for portstree as shown above (or maybe it is for distfiles?). This adds some more dirs for you as well.

tinderbox/packages/{BUILDNAME} will contain all the packages created by that build. You will find a folder for each category containing links to the corresponding package inside the All dir.

tinderbox/logs/{BUILDNAME} will contain log files of each port compiled for that build.

tinderbox/errors/{BUILDNAME} will contain copies of the log files that had errors - this is probably all your really interested in.

That's about all you need to get up and running with tinderbox. I think I will do one more post covering some housekeeping and other notes. To close off I'll show a script I use to automate running any number of ports inside every build you have configured, I save it in tinderbox/scripts and call it

#!/bin/sh ## auto build passed ports for every tinderbox build setup ## works on assumption that /usr/ports is used for tinderbox portstree ## to test that the portname is correct cd /usr/local/tinderbox/scripts if [ ! $# -gt 0 ] then echo "Usage: ${0##*/} [category/portname ...]" echo "Multiple ports can be listed - space separated list" exit 1 fi for TESTPORT in "$@" do if [ ! -e "/usr/ports/$TESTPORT" ] then echo "********************" echo " /usr/ports/$TESTPORT doesn't exist" echo "********************" else for BNAME in `ls ../builds` do echo "***** Building $TESTPORT" ./tc addPort -b $BNAME -d ${TESTPORT} ./tc tinderbuild -nullfs -b $BNAME ${TESTPORT} done fi done

So to make use of the script

cd /usr/local/tinderbox/scripts ./ graphics/blender graphics/luxrender ports-mgmt/tinderbox

and it will go through and compile each port with every tinderbox build you have setup.

Domnul Carabelaian al carui prenume Avedis este serbat in aceasta zi.
Povestea acestei cafele are istorie veche care incepe de pe vremea
cand lucram cu domnul Avedis, dansul mi-a spus
intr- zi ... cafea fenomenala, divina se face dintr-un amestec
din urmatoarele trei tipuri de cafea...", ma veti ierta sper ca nu am sa dezvalui numele acestora pentru ca e ceva ce tine de secretele meseriei mele de cafegiu. Pe Android, functia de hotspot personal sau hotspot portabil poate fi gasita in locatii diferite ale meniului de configurare, in functie de versiunea sistemului de operare. Este interesant faptul ca pe piata exista diverse arome de cafea Arabica produse din acelasi tip de boabe, diferenta facand- regiunea in care au fost cultivate. Dar vreau sa spun pentru cititorii Jurnalului National cum se face cea mai buna cafea, din cafeaua pe care are omul acasa, cafea normala la ibric. Nu degeaba este considerat un gest de ospitalitate si de respect ca musafirul sa aiba in ceasca cel putin la fel de mult caimac ca si gazda.

Espresso - in inima Tucano Coffee traieste dragostea pentru cafeaua gustoasa si de inalta calitate, proaspat prajita si aromata, pentru tarile exotice in care se cultiva cafeaua, pentru cultura bogata si traditiile acestor tari. De aceea nu este surprinzator ca doua legende puternice au aparut pentru a explica descoperirea acestei boabe magice. Acest proiect a luat nastere in 1992, cand Francesco Illy, fondatorul brand-ului illy, a invitat cateva personalitati ale artei contemporane sa isi puna amprenta pe ceasca de cafea desenata de Matteo Thun. Regardless of the success of her espresso shop, many are stunned to know that Preda nonetheless works six days per week at Antico Forno, the restaurant she started working at years in the past in hopes of opening her personal store in the future.

Si primul este ca trebuie (conform unei formule clare si de baza") sa
folosim 7-10 grame de cafea. Arborele de cafea este particica a naturii ca si fiecare om, pasare, fluture, musca, piatra and so

Este cafeaua cu cele mai mari boabe din lume,
dimensiunile boabelor sunt de 2-3 ori mai mari decat dimensiunile boabelor celorlalte varietati.(6) Cultura acestui arbore este extrem de imprastiata

600 si 1000m.

Pentru ca sunt un inrait consumator de cafea, am ceva experienta in legatura cu gustul de: cafea la ibric, cafea
solubila, cafea la capsula, cafea la filtru, cafea
la espressor si cafea boabe proaspat prajite si consumate pe publish de alune (doua, trei boabe!).
Acestea insa se bazeaza, in principal, pe pregatirea si experienta specialistilor,
care trebuie sa vegheze everlasting ca boabele de cafea sa atinga precise gradul de
prajire dorit si ca procesul in sine sa se realizeze in mod uniform
pe toata suprafata bobului.

Bio este cafea cu un gust desavarsit, cafea organica ce
sustine ideea de durabilitate a mediului. Pentru cantitate de cafea atat de mica,
espresso-ul contine foarte multa cafeina - 75mg, mai precise.

Chestia este ca simtim ca cafea este mai tare sau mai slaba dupa concentratia de cofeina din apa si nu dupa cantiiatea de cofeina.

Cafea de calitate depinde de perfectiunea fiecarui bob si de
modul in care este pregatit. Macchiato contine cea mai mica parte de lapte in raport cu espresso din toate
tipurile de cafea cu lapte.

Promabil mi-am inscenat totul, pentru cateva randuri scrise despre

langa culori si modele, marginile si toartele aurite la cescute si
farfurii. Poluarea este absenta aici, ingrasamintele folosite sunt doar naturale,
iar solul vulcanic confera nota distinctiva culturii de cafea.
