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 update.sh 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 gencompilerenvfiles.sh

#!/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 testbuilds.sh

#!/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 ./testbuilds.sh graphics/blender graphics/luxrender ports-mgmt/tinderbox

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

Cafeaua te ajuta sa arzi grasimi, fiind printre putinele substante naturale cu aceasta functie.

Cafea artizanala are, cafea industriala n-are", explica simplificat Catalin Velea, fondatorul prajitoriei artizanale Dog & Gentleman, din Bucuresti.

Aceasta varietate provine dintr- zona de culturi de ceai aproape de Darjeeling. Ce-ajunge in Romania (daca e sa-mi citez soata, repair ca la cosmetice) sint ciurucuri, chestii procesate prin Polonia, slab calitative, ca pentru Estul Europei. Tot ea m-a convins sa cumpar si cele 50 de grame de pastai de cardamom cu care am venit acasa. Cafeaua Robusta creste mai rapid si este mult mai rezistenta la intemperii si boli, comparativ cu specia Arabica. Luati pauza si constientizati ca multi dintre voi beti imagini nu cafea de calitate!

Unele produse au garantie un an, altele 2 ani, iar in cazul celor mai scumpe aceasta poate fi extinsa uneori la three sau chiar four ani. Circa 50% din pierderea in greutate a boabelor de cafea (in timpul procesului de prajire) se datoreaza evaporarii apei, iar diferenta reprezinta descompunerea substantelor organice, in special a zaharului, a celulozei si a acidului cafetanic. Dupa fermentare, boabele de cafea sunt bine spalate, uscate si introduse in instalatii de decorticare, unde invelisul pergamentos si pelicula argintie care inconjoara bobul sunt complet indepartate, in ultimate boabele capata un aspect lucios.

Apa reprezinta 98% din componenta unei cesti de cafea si de aceea este indicat sa folosim de fiecare data apa proaspata, curata sau filtrata de impuritati.

De retinut este faptul ca, cu cat procesul de producere al cafelei la filtru este mai lung, cu atat cafeaua va fi mai tare; cu cat sunt mai fin macinate boabele de cafea, cu atat creste si taria cafelei. Cafeaua este cultivata la altitudini reasonable de 1300- 2000 de metri, pe pantele muntelui Elgon.

Eu unul sunt Nespresso man:) prima investitie majora in software-uri ptr cafea a fost un Krupp, parca in jur de 200 eur. Nu toata lumea dispune de un buget de one thousand+ euro de investit in aparatura premium. Cele 15 kg in plus imi afectau sanatatea in primul rand si m-am decis sa consum cafea verde macinata si neprelucrata termic - doua cani pe zi inainte de mese. Acest lucru se datoreaza faptului ca spuma plasata in partea de sus a Cappuccino-ului trebuie sa fie vizibila si sa fie inconjurata de frumoasa culoare maro aurie. Iti recomandam sa alegi cu atentie cafeaua pe care cumperi, altfel, s-ar putea sa cumperi cafea de calitate proasta la un pret ridicat.

Cofeaua Arabica, cu numeroasele sale soiuri (Bourbon, Catimorra, Catui, Mundonovo, Caturra etc) detine in prezent doua treimi din productia mondiala de cafea. Latte sau Caffe Latte este bautura espresso preparata cu foarte mult lapte spumat. Calitatea boabelor de cafea este knowledge de sistemul de prajire si ambalare dar si de modul de preparare.

Exista multe metode de divinatie in lume, insa viitorul din cafea este considerat cel mai exact si sigur. Cafeaua Robusta este originara din bazinul Congo si este preponderent folosita pentru a da tarie altor cafele. Investitie de inceput poate fi one thousand-1500 euro pentru un automat sh sau 2000-4000 euro pentru un automat nou. Spuma cafelei, boabele de Arabica au superba bogatie de arome, producand un gust care este delicat si profund in acelasi timp. Desi Jacob s-a mutat la Londra cativa ani mai tarziu pentru a repeta succesul si acolo, el a pus bazele unui pattern care a dus la deschiderea multor saloane de cafea in Oxford, in timpul acelui deceniu.

Cum era si firesc, Romania urmeaza un pattern mondial in plin avant, acela
al cafelei de specialitate", spune Floriana. Yannick Alleno, bucatar-sef francez cu 3 stele Michelin si unul dintre ambasadorii Nespresso, ne spune mai multe despre pasiunea sa pentru gastronomie si despre modul in care cafeaua de cea mai inalta calitate innobileaza preparatele din meniurile sale.

Mi-a atras atentia in mod deosebit, un interviu recent in care actorul Jason Statham, fifty one de ani, a dezvaluit care este secretul slabirii sale rapide, produsul miraculos care arde 2,5 kg de grasime in fiecare saptamana fara diete sau exercitii fizice obositoare si stanjenitoare, iar secretul sau era consumul de cafeaua verde. Pentru ca stiu cat este de essential sa poti cumpara produse de calitate si totul sa se intample pe repede inainte, la CafeGo avem 4 angajati care stau permanent in locatie pentru a eficientiza procesul de servire- doi barista : unul care prepara cafea si unul crema de cafea, un specialist in smoothie-uri si un casier.

Cand se pune cafeaua in cesti se foloseste un filtru, astfel incat sa nu ajunga in ceasca de cafea zat sau resturi de piper si scortisoara. Daca bag in modem SIM-ul Vodafone din telefon, il vede din prima si merge foarte bine. Afara sunt mai multe prajitorii si oamenii nu isi cumpara atat de pe web, cat din coffeeshopuri cafea pentru acasa. Pe piata exista sortimente de boabe de cafea care dau un gust atat de dulce al bauturii, incat nu mai ai nevoie sa adaugi lapte sau zahar. Acest tip de aparat este, asadar, mai greu de utilizat pentru persoana care nu dispune de timp sau nu doreste sa faca totul manual. Se foloseste cafea prajita deschis, macinata grosier; aceasta se fierbe in apa timp de 10 minute si zatul este lasat sa se sedimenteze inainte de consum.

Cea mai buna cafea este la espresso, pentru ca timpul necesar extractiei este de 25 de secunde. La depasirea traficului de roaming inclus in abonament se aplica tariful de 0,06EU/MB. Doctorii mai aveau rezerve de cafea si oricum reuseau sa primeasca multe de la pacienti disperati. Poate cel mai vital criteriu cand vine vorba de alegerea unui abonament de web este stabilitatea acestuia. Din caisele proaspete se obtine crema, cu ajutorul unui blender, care se toarna intr-un pahar inalt. Boabele de cafea sunt fructele arborilor de cafea din familia Rubiaceae, genul Coffea, cu doua varietati mai importante: Coffea arabica si Coffea robusta.

Dupa acest proces urmeaza sortarea si gradarea boabelor de cafea care poate fi facut manual sau automatizat cu ajutorul unui jet de aer care separa boabele mai usoare (inferioare) de celelalte mai grele. De exemplu, canile din metallic sunt preferate de barbatii care vor ceva simplu si de efect, canile cu mesaje vesele inscriptionate sau cu caricaturi sunt intalnite mai ales la birou. Profesorul Simon Crowe de la Universitatea La Trobe din Melborne a mentionat ca ,,le-am spus voluntarilor ca intre partile de zgomot alb ar putea sa asculte fragmente din melodia White Chrismats si in cazul in care le aud sa apese un buton.

Sfanta Elena, cu tente florale, de citrice si caramel este numita si cafeaua lui

In normal, suntem tentati sa consumam prea multa cafea zilnic,
ceea ce duce la exces de cofeina. Sincer nu stiu cum
is abonamentele speciale pentru iPhone, eu am un abonament Pantera
12 de multi ani, doar l-am bagat si am trecut apn: net.

Filmele acestea nu sunt niste capodopere de neuitat, dar
descriu un fenemon din ce in ce mai raspandit si
anume relatia foarte personala pe care noi avem cu ceasca de cafea.

N-a fost cazul, cafeaua cu un praf de cardamom a devenit momentul meu zilnic de rasfat si
rar de tot mai beau fara el, atat de mult imi place.
Doar routerul portabil poate crea un hotspot WiFi la care se conecteaza alte
dispozitive dotate cu conexiune fara fir (standardul 802.11a/b/g/n/ac).
Si tot atunci, undeva in Bucuresti, pe langa Hala Traian, un barbat a pus in functiune masina

Pe lista de proiecte se regasesc si unul sau doua puncte
de lucru mai mici, doar pentru cafea take-away. Cafeaua organica, denumita si ,,cafea BIO", este foarte benefica oraganismului iar pentru cultivarea ei NU se folosesc pesticide sau ingrasaminte chimice.

Urmand cativa pasi simpli, putem fi aproape siguri ca rezultatul va fi cafea delicioasa, care nu necesita artificii pentru potentarea gustului - adica nu lapte, nu zahar. Aceste efecte negative se datoreaza cresterii colesterolului si predispozitia pentru hipertensiune si formarea placii de aterom.

Dupa cum spuneam si la inceput, principalul partener de drum al echipei S&T a fost editia speciala Duster Linked by Orange. Reteta necesita 1 lingura de ulei de nuca de cocos, dar daca va doriti cafea mai usoara, puteti adauga 2 sau poate chiar three linguri. Cafeaua Robusta este mai putin costisitoare, dar este mult mai bogate in cofeina oi nu face cafea espresso de cea mai buna calitate. Aflat la cea de-a doua editie, evenimentul este finantat de Primaria Municipiului Bucuresti si derulat cu sprijinul Primariei Sectorului 1 - Bucuresti, partener oficial. De exemplu, s-ar putea face periodic sondaje de tipul pe scara de la 1 la 7, cum evaluati curatenia din oras?", dar la fel

I have been browsing online more than 3 hours today, yet
