# TODO
|
||||
|
||||
## Améliorer rtoinst
|
||||
|
||||
ajouter le support de pffprofile pour deploydb
|
||||
|
||||
## Refaire/repenser les fonctions evalX
|
||||
|
||||
dans chaque exemple, on affiche l'invocation de evalX suivi de l'équivalent en
|
||||
syntaxe standard
|
||||
|
||||
- evala permet de traiter des tableaux
|
||||
~~~
|
||||
evala with array // add a b c
|
||||
array=("${array[@]}" a b c)
|
||||
~~~
|
||||
les fonctions à utiliser pour le traitement sont configurées avec des
|
||||
variables spéciales. par exemple, on peut indiquer que la commande add
|
||||
ci-dessus est en réalité gérée par la fonction array_add et que c'est une
|
||||
commande de type modify qui prend en premier argument le nom du tableau:
|
||||
~~~
|
||||
__evala_add_func=array_add
|
||||
__evala_add_type=m
|
||||
__evala_add_arg=first
|
||||
~~~
|
||||
en fonction du type de fonction, les arguments supplémentaires supportés sont
|
||||
différents. par défaut, la fonction à utiliser est du même nom que la
|
||||
commande, est du type scalar, et prend comme argument @
|
||||
Ainsi les deux commandes suivantes sont équivalentes:
|
||||
~~~
|
||||
evala with array // echo
|
||||
echo "${array[@]}"
|
||||
~~~
|
||||
et assument les définitions suivantes:
|
||||
~~~
|
||||
__evala_echo_func=echo
|
||||
__evala_echo_type=s
|
||||
__evala_echo_arg=@
|
||||
~~~
|
||||
|
||||
- evalx permet d'utiliser toutes ces fonctions ensemble
|
||||
~~~
|
||||
evalx seq 5 //p grep -v 3 //a prepend prefix // append suffix //c echo
|
||||
array=($(seq 5 | grep -v 3)); array=(prefix "${array[@]}"); array=("${array[@]}" suffix); echo "${array[@]}"
|
||||
|
||||
# à partir du mode evala, on peut exécuter directement les arguments du
|
||||
# tableau comme une commande en terminant par //c
|
||||
evalx -a with array // prepend echo //c
|
||||
array=(echo "${array[@]}"); "${array[@]}"
|
||||
~~~
|
||||
evalx commence par défaut en mode evalc. il est possible avec les options -i,
|
||||
-s, -a, -c, -p, -m de forcer respectivement evali, evals, evala, evalc, evalp,
|
||||
evalm
|
||||
|
||||
- Il faudra réfléchir à comment sortir du mode evalm pour utilisation avec
|
||||
evalx. ou alors on part du principe que evalm est toujours en fin de chaine.
|
||||
|
||||
## Faire la fonction cmdx
|
||||
|
||||
cmdx permet de lancer une commande avec les arguments qui sont générés par
|
||||
evalx. cmdx commence par défaut en mode evalm. Par exemple, les deux commandes
|
||||
suivantes sont équivalentes:
|
||||
~~~
|
||||
cmdx etitle //"Copie de " basename "$src" //" vers " ppath "$dest"
|
||||
etitle "Copie de $(basename "$src") vers $(ppath "$dest")"
|
||||
~~~
|
||||
|
||||
Comme pour evalx, les options -i, -s, -a, -c, -p, -m permettent de forcer
|
||||
respectivement les modes evali, evals, evala, evalc, evalp, evalm. Par exemple
|
||||
les deux commandes suivantes sont équivalentes:
|
||||
~~~
|
||||
cmdx -c echo a // b
|
||||
echo "$(b "$(a)")"
|
||||
~~~
|
||||
|
||||
## Faire la fonction checkx
|
||||
|
||||
checkx permet de tester le résultat d'une commande evalx. elle s'utilise de
|
||||
cette manière:
|
||||
~~~
|
||||
checkx cmds... OP VALUE
|
||||
~~~
|
||||
|
||||
Les opérateurs sont de la forme:
|
||||
~~~
|
||||
is -n|notempty
|
||||
is -z|empty
|
||||
is ok
|
||||
is ko
|
||||
== value
|
||||
!= value
|
||||
etc.
|
||||
~~~
|
||||
|
||||
checkx remplace testx avec une syntaxe plus naturelle. si aucun script
|
||||
n'utilise les fonctions testx, peut-être peut-on simplement supprimer les
|
||||
fonctions testx et renommer checkx en testx
|
||||
|
||||
Comme pour evalx, les options -i, -s, -a, -c, -p, -m permettent de forcer
|
||||
respectivement les modes evali, evals, evala, evalc, evalp, evalm. Par exemple
|
||||
les deux commandes suivantes sont équivalentes:
|
||||
~~~
|
||||
checkx -p a // b == c
|
||||
[ "$(evalp a // b)" == c ]
|
||||
~~~
|
||||
|
||||
Les commande suivantes sont équivalentes deux à deux:
|
||||
~~~
|
||||
checkx cmd is -z
|
||||
[ -z "$(evalx cmd)" ]
|
||||
|
||||
checkx cmd is ok
|
||||
evalx cmd; [ $? -eq 0 ]
|
||||
|
||||
checkx cmd is ko
|
||||
evalx cmd; [ $? -ne 0 ]
|
||||
|
||||
checkx cmd == value
|
||||
[ "$(evalx cmd)" == value ]
|
||||
~~~
|
||||
|
||||
## Faire la fonction storex
|
||||
|
||||
storex permet de mettre le résultat d'une fonction evalx dans une variable ou de
|
||||
l'ajouter à un tableau. l'idée est d'avoir la même syntaxe que checkx. je ne
|
||||
suis pas encore tout à fait sûr que ce soit une bonne chose.
|
||||
|
||||
Les commande suivantes sont équivalentes deux à deux:
|
||||
~~~
|
||||
storex cmd to var
|
||||
var="$(evalx cmd)"
|
||||
|
||||
storex cmd to var
|
||||
setx var=cmd
|
||||
|
||||
storex -a cmd to array
|
||||
array_add array "$(evalx cmd)"
|
||||
|
||||
storex -r cmd from array
|
||||
array_del array "$(evalx cmd)"
|
||||
~~~
|
||||
|
||||
syntaxes alternatives
|
||||
~~~
|
||||
storex cmd to var
|
||||
addx cmd to array
|
||||
removex cmd from array
|
||||
~~~
|
||||
|
||||
alternatives
|
||||
~~~
|
||||
setx var=cmd
|
||||
evalx cmd // array_add array
|
||||
evalx cmd // array_del array
|
||||
~~~
|
||||
|
||||
note: il ne semble pas nécessaire au vu de l'alternative d'implémenter storex,
|
||||
addx, removex.
|
||||
|
||||
par contre, il faut corriger un bug d'evalc: la dernière commande doit être
|
||||
exécutée telle quelle. en effet,
|
||||
~~~
|
||||
evalc a // b
|
||||
~~~
|
||||
devrait être équivalent à
|
||||
~~~
|
||||
b "$(a)"
|
||||
~~~
|
||||
mais en fait c'est plutôt
|
||||
~~~
|
||||
echo "$(b "$(a)")"
|
||||
~~~
|
||||
et ça pose problème, notamment si b initialise des variables, etc.
|
||||
|
||||
## Fonctions diverses
|
||||
|
||||
`retcode cmd`
|
||||
: affiche le code de retour de cmd. équivalent à `cmd; echo $?`

Syntaxes
|
||||
: base_arg MODE
|
||||
: base_arg [MODE] -OPTIONS ACTION DESC
|
||||
: base_arg [MODE] VARIABLE DESC
|
||||
|
||||
MODE peut être l'un des caractères '+', '-', '%' et a un effet sur l'analyse
|
||||
entière de la ligne de commande
|
||||
* Les caractères '+' et '-' influent sur la méthode d'analyse. Par défaut, les
|
||||
options sont valides n'importe où sur la ligne de commande. Avec '+',
|
||||
l'analyse s'arrête au premier argument qui n'est pas une option. Avec '-', les
|
||||
options sont valides n'importe ou sur la ligne de commande, mais les arguments
|
||||
ne sont pas réordonnés, et apparaissent dans l'ordre de leur mention.
|
||||
* Le caractère '%' demande que toutes les variables mentionnées à partir de ce
|
||||
moment soient initialisées. Elle sont garanties d'être vides.
|
||||
|
||||
Avec la première syntaxe, on définit précisément l'option. Deux formes sont
|
||||
supportées. La forme détermine le type d'action
|
||||
* Avec la forme '-OPT VAR[=VALUE]', OPT est une description d'option, VAR un nom
|
||||
de variable à mettre à jour, et VALUE une valeur éventuelle pour les options
|
||||
sans argument. Si plusieurs options sont mentionnées, séparées par des
|
||||
virgules, alors tous les options partagent les mêmes paramètres.
|
||||
|
||||
OPT peut être de la forme '-o' ou '--longopt' pour des options sans arguments.
|
||||
Dans ce cas, VAR obtient le nombre de fois que l'option est mentionnée (vide
|
||||
pour aucune mention, '1' pour une seule mention, etc.), sauf si on utilise la
|
||||
forme VAR=VALUE, auquel cas la variable obtient la valeur VALUE, et le nombre
|
||||
d'occurences de l'option n'est pas compté.
|
||||
|
||||
Pour faciliter la lecture:
|
||||
* '--longopt .' est équivalent à '--longopt longopt'
|
||||
* '--longopt: .' est équivalent à '--longopt: longopt='
|
||||
|
||||
Avec les formes '-o:' et '--longopt:', l'option prend un argument obligatoire.
|
||||
Avec les formes '-o::' et '--longopt::', l'option prend un argument facultatif
|
||||
(dans ce cas, la valeur de l'option sur la ligne de commande doit
|
||||
obligatoirement être collée à l'option.)
|
||||
|
||||
Si ces options sont mentionnées plusieurs fois sur la ligne de commande, alors
|
||||
la variable de destination est un tableau qui contient toutes les valeurs. Le
|
||||
traitement de la valeur d'une variable dépend de la forme utilisée.
|
||||
* Avec une option sans argument, le comportement est celui décrit ci-dessus.
|
||||
* Avec une option qui prend des arguments, la forme '-o: VAR' considère que
|
||||
VAR est un tableau qui contiendra toutes les valeurs mentionnées dans les
|
||||
options. Avec la forme '-o: VAR=', la variable n'est pas un tableau et
|
||||
contient toujours la dernière valeur spécifiée.
|
||||
* Dans la forme 'opt \$cmd', la commande cmd est executée avec eval *dès* que
|
||||
l'option est rencontrée. La variable option_ contient l'option, e.g. '-o' ou
|
||||
'--longopt'. Le cas échéant, la variable value_ contient la valeur de
|
||||
l'option. La fonction 'set@ NAME' met à jour la variable NAME, soit en lui
|
||||
donnant la valeur \$value_, soit en l'incrémentant, suivant le type d'option.
|
||||
La fonction 'inc@ NAME' incrémente la variable NAME, 'res@ NAME [VALUE]'
|
||||
initialise la variable à la valeur VALUE, 'add@ NAME [VALUE]' ajoute VALUE à
|
||||
la fin du tableau NAME. Par défaut, VALUE vaut \$value_
|
||||
|
||||
Avec la deuxième syntaxe, l'option est déterminée sur la base du nom de la
|
||||
variable.
|
||||
* Une variable de la forme 'sansarg' est pour une option simple qui ne prend pas
|
||||
d'argument
|
||||
* Une variable de la forme 'avecarg=[default-value]' est pour une option qui
|
||||
prend un argument.
|
||||
L'option générée est une option longue. En l'occurence, les options générées
|
||||
sont respectivement '--sansarg' et '--avecarg:'
|
||||
Les variables et les options sont toujours en minuscule. Pour les variables, le
|
||||
caractère '-' est remplacé par '_'. Si une option contient une lettre en
|
||||
majuscule, l'option courte correspondante à cette lettre sera aussi reconnue.

~~~

|

~~~
|
||||
|
||||
En commençant avec la valeur initiale \$1, les arguments \$2..* sont des
|
||||
opérations à appliquer dans l'ordre.
|
||||
|
||||
Les opérations suivantes considèrent que la valeur courante est un nom de
|
||||
variable:
|
||||
~~~
|
||||
:- := :? :+ deref dcount
|
||||
~~~
|
||||
|
||||
Toutes les autres opérations travaillent directement avec la valeur
|
||||
courante. Les opérations suivantes appliquent une transformation:
|
||||
~~~
|
||||
# % / : ^ , +# -# +% -% + - mid repl
|
||||
~~~
|
||||
IMPORTANT: aucune de ces fonctions ne met en échappement les valeur des
|
||||
patterns. Ainsi, si un pattern contient des caractères interdits comme \\ ou \$,
|
||||
il faut d'abord le traiter avec _qval()
|
||||
|
||||
Les opérations suivantes font un test sur la valeur et retournent immédiatement:
|
||||
~~~
|
||||
= == != < > -eq -ne -lt -le -gt -ge -n -z
|
||||
~~~
|
||||
|
||||
La syntaxe des opérateurs standards de bash est reprise autant que possible, i.e
|
||||
si on a l'habitude d'écrire ${varOP} en bash, alors la syntaxe à utiliser à
|
||||
priori est 'base_evals var OP' ou 'base_evals var deref OP' suivant les
|
||||
opérateurs.
|
||||
|
||||
Autres opérateurs:
|
||||
~~~
|
||||
deref indirection
|
||||
dcount nombre d'éléments du tableau
|
||||
+#STR ajouter un préfixe
|
||||
-#STR supprimer un préfixe
|
||||
+%STR ou +STR ajouter un suffixe
|
||||
-%STR ou -STR supprimer un suffixe
|
||||
mid RANGE traiter la chaine avec base_strmid()
|
||||
repl FROM TO traiter la chaine avec base_strrepl()
|
||||
~~~

Tout autre opérateur est traité comme un appel à une fonction qui prend un seul

argument, la valeur courante, et qui affiche le résultat."

`deploydb` est un moyen de décrire des informations de déploiement ou de
|
||||
configuration à propos de certains objets (hôtes, modules, webapps, woapps,
|
||||
etc.)
|
||||
|
||||
# Syntaxe
|
||||
|
||||
Le format du fichier de configuration est volontairement simple. Toute la
|
||||
logique est implémentée dans les clients qui accèdent à l'information stockée
|
||||
|
||||
Le fichier contient deux sortes d'informations:
|
||||
* définition d'objet
|
||||
* définition de faits
|
||||
|
||||
Les lignes vides ou commençant par '#' sont ignorées.
|
||||
Si une ligne commence par un espace, elle est fusionnée avec la ligne
|
||||
précédente.
|
||||
|
||||
## Définition d'objet
|
||||
|
||||
Une définition d'objet a le format suivant:
|
||||
~~~
|
||||
otype oid[=values] [ATTRS...] [LINKS...]
|
||||
~~~
|
||||
|
||||
`otype`
|
||||
: type d'objet à créer ou à mettre à jour
|
||||
|
||||
`oid`
|
||||
: identifiant de l'objet à créer ou à mettre à jour
|
||||
|
||||
`values`
|
||||
: valeurs de l'objet, séparées par des virgules
|
||||
|
||||
`ATTR`
|
||||
: attribut de l'objet
|
||||
|
||||
`LINK`
|
||||
: définition d'objet lié
|
||||
|
||||
Une définition d'attribut a l'un des formats suivants:
|
||||
~~~
|
||||
name[=value]
|
||||
name+[=value]
|
||||
name-[=value]
|
||||
name%[=value]
|
||||
~~~
|
||||
|
||||
Les attributs sont multivalués, et par défaut, on rajoute la nouvelle valeur aux
|
||||
valeurs existantes sauf si elle existe déjà dans l'attribut.
|
||||
|
||||
value vaut par défaut 'true', ce qui n'est pas la même chose qu'une valeur
|
||||
vide. comparer les deux définitions suivantes:
|
||||
~~~
|
||||
first # first vaut 'true'
|
||||
second= # second vaut ''
|
||||
~~~
|
||||
|
||||
Les types de mise à jour valides sont:
|
||||
* `=` ajout de la valeur si l'attribut ne la contient pas déjà
|
||||
* `+=` ajout inconditionnel d'une valeur à l'attribut
|
||||
* `-=` suppression d'une valeur de l'attribut
|
||||
* `%=` remettre à zéro l'attribut d'abord
|
||||
|
||||
Ainsi, les définitions suivantes sont équivalentes deux à deux:
|
||||
~~~
|
||||
attr=value attr=value # le doublon est supprimé
|
||||
attr=value # c'est comme si on ne spécifie la valeur qu'une seule fois
|
||||
|
||||
attr=value attr%=first attr=second
|
||||
attr=value attr-=value attr=first attr=second
|
||||
~~~
|
||||
|
||||
Une définition de lien a le format suivant:
|
||||
~~~
|
||||
-otype oids... [ATTRS...]
|
||||
~~~
|
||||
|
||||
`otype`
|
||||
: type de l'objet lié
|
||||
|
||||
`oids`
|
||||
: liste d'identifiants d'objets liés séparés par des virgules
|
||||
|
||||
`ATTR`
|
||||
: attribut à rajouter à la définition du lien
|
||||
|
||||
Voici un exemple complet:
|
||||
~~~
|
||||
humain bob nom=Payet prenom=Robert
|
||||
age=42
|
||||
desc="un humain qui a un père, une mère et deux voitures"
|
||||
-humain eric type=pere
|
||||
-humain martine type=mere
|
||||
-vehicule titine,bumblebee
|
||||
humain eric nom=Payet prenom=Eric
|
||||
humain martine nom=Payet prenom="Martine Joséphine"
|
||||
vehicule titine marque=Citroen immatriculation=BX-467-PM
|
||||
vehicule bumblebee marque=Camaro type=autobot
|
||||
~~~
|
||||
|
||||
## Définition de faits
|
||||
|
||||
Un fait est l'affirmation d'un lien d'action ou d'état entre deux objets,
|
||||
décrit par un verbe. Par exemple, pour décrire le fait que bob mange une
|
||||
tarte, on écrirait:
|
||||
~~~
|
||||
humain bob
|
||||
aliment tarte
|
||||
|
||||
-humain bob
|
||||
mange -aliment tarte
|
||||
~~~
|
||||
|
||||
Une définition de fait a le format suivant:
|
||||
~~~
|
||||
-sotype soids... [DEFATTRS...]
|
||||
verb -totype toids... [FACTATTRS...]
|
||||
...
|
||||
~~~
|
||||
|
||||
`sotype`
|
||||
`totype`
|
||||
: types d'objets source et cible
|
||||
|
||||
`soid`
|
||||
`toid`
|
||||
: identifiants des objets source et cible
|
||||
|
||||
`verb`
|
||||
: identifiant du lien entre la source et la destination. en général, il s'agit
|
||||
d'un verbe d'action ou d'état conjugué à la 3ème personne du singulier.
|
||||
|
||||
si le verbe commence par `~` alors la définition est inversée. par exemple,
|
||||
les deux faits suivants sont rigoureusement équivalents:
|
||||
~~~
|
||||
-otype src verb -otype dest
|
||||
-otype dest ~verb -otype src
|
||||
~~~
|
||||
cela permet de supporter les cas où la définition inverse est plus facile.
|
||||
|
||||
`DEFATTR`
|
||||
: attribut pour tous les faits définis dans cette déclaration
|
||||
|
||||
`FACTATTR`
|
||||
: attribut spécifique au fait défini
|
||||
|
||||
# deploydb
|
||||
|
||||
Le script `deploydb` permet d'interroger la base de données ou de lancer une
|
||||
fonction pour traiter le contenu de la base de données
|
||||
|
||||
Dans ce document, `DEPLOYDBDIR` désigne le répertoire du script `deploydb`
|
||||
|
||||
Options
|
||||
`-c, --config CONFIG`
|
||||
: spécifier un fichier de configuration à charger. la valeur par défaut est
|
||||
`deploydb.conf`
|
||||
|
||||
si le fichier de configuration n'est pas spécifié ou est spécifié sans chemin,
|
||||
`deploydb:path` est initialisé avec la valeur par défaut suivante:
|
||||
~~~
|
||||
~/etc/deploydb:/var/local/deploydb:DEPLOYDBDIR
|
||||
~~~
|
||||
|
||||
sinon, `deploydb:path` est initialisé avec le répertoire de CONFIG
|
||||
|
||||
`-m, --module MODULE`
|
||||
: spécifier un module supplémentaire à charger. le module python effectivement
|
||||
cherché dans le path et chargé est `MODULE_module`. La liste par défaut des
|
||||
modules à charger contient un seul élément, `base`, ce qui signifie que le
|
||||
module `base_module` est chargé. Les modules permettent de définir de la
|
||||
logique pour les objets, ou l'outil à lancer.
|
||||
|
||||
`-r, --func FUNC`
|
||||
: spécifier le nom de la fonction à lancer après le chargement des modules et
|
||||
des fichiers de configuration. La valeur par défaut est `base.query`, qui
|
||||
interroge la base de données et affiche son contenu.
|
||||
|
||||
La fonction est appelée avec les arguments de la ligne de commande, sans les
|
||||
options, qui sont traitées en amont.
|
||||
|
||||
`--dump`
|
||||
: afficher le contenu complet de la base de données, pour débugger. ignorer
|
||||
l'option `-r`
|
||||
|
||||
# Module base
|
||||
|
||||
Le module `base` chargé par défaut définit
|
||||
* les objets de type `deploydb`, `host`
|
||||
* la fonction `query()`
|
||||
|
||||
## deploydb
|
||||
|
||||
En créant des instances de cet objet avec des identifiants normalisés, il est
|
||||
possible de modifier la configuration.
|
||||
|
||||
`deploydb path dir=CONFDIR`
|
||||
: définir les répertoires de recherche pour les fichiers de configuration
|
||||
spécifiés sans chemin. dans ce document, cette valeur est appelée
|
||||
`deploydb:path`
|
||||
|
||||
`deploydb include file=CONFIG`
|
||||
: définir des fichiers de configuration supplémentaire à charger. Si les
|
||||
fichiers sont spécifiés sans chemin, il sont cherchés dans `deploydb:path`
|
||||
|
||||
`deploydb loadcsv file=CSVFILE`
|
||||
: charger des définitions d'objets depuis des fichiers CSV. Si les fichiers sont
|
||||
spécifiés sans chemin, ils sont cherchés dans `deploydb:path`
|
||||
|
||||
L'attribut `otype_col` qui vaut par défaut `otype` permet de définir la
|
||||
colonne qui contient le type d'objet. L'attribut `otype` permet de spécifier
|
||||
le type d'objet si la colonne n'existe pas dans le fichier.
|
||||
|
||||
L'attribut `oid_col` qui vaut par défaut `oid` permet de définir la colonne
|
||||
qui contient l'identifiant d'objet à créer.
|
||||
|
||||
Toutes les autres colonnes du fichier sont utilisées pour définir les
|
||||
attributs des objets.
|
||||
|
||||
## host
|
||||
|
||||
Cet objet définit un hôte vers lequel on peut par exemple déployer un artifact.
|
||||
|
||||
`host * domain=DOMAIN.TLD`
|
||||
: définir un domaine par défaut pour tous les hôtes spécifiés sans domaine
|
||||
|
||||
Les attributs suivants sont supportés:
|
||||
|
||||
`host`
|
||||
: nom d'hôte. le domaine par défaut est ajouté le cas échéant. pour ne pas
|
||||
rajouter un domaine, spécifier le nom avec un point final e.g `localhost.`
|
||||
|
||||
`hostname`
|
||||
: nom d'hôte sans le domaine
|
||||
|
||||
`domain`
|
||||
: domaine sans le nom d'hôte
|
||||
|

# nulib
|
||||
|
||||
nulib est une librairie de fonctions shell et python, ainsi qu'un
|
||||
ensemble d'utilitaires basés sur ces librairies
|
||||
|
||||
## Prérequis
|
||||
|
||||
nulib est conçu pour tourner sur des versions récentes de Linux et
|
||||
requière bash 4.1+, GNUawk 3.1+ et Python 2.6
|
||||
|
||||
Les systèmes cibles sont Debian 8+ (jessie, stretch) et Oracle Linux 6+
|
||||

ajp - an AJP 1.3/WSGI gateway.
|
||||
|
||||
For more information about AJP and AJP connectors for your web server, see
|
||||
<http://jakarta.apache.org/tomcat/connectors-doc/>.
|
||||
|
||||
For more information about the Web Server Gateway Interface, see
|
||||
<http://www.python.org/peps/pep-0333.html>.
|
||||
|
||||
Example usage:
|
||||
|
||||
#!/usr/bin/env python
|
||||
import sys
|
||||
from myapplication import app # Assume app is your WSGI application object
|
||||
from ajp import WSGIServer
|
||||
ret = WSGIServer(app).run()
|
||||
sys.exit(ret and 42 or 0)
|
||||
|
||||
See the documentation for WSGIServer for more information.
|
||||
|
||||
About the bit of logic at the end:
|
||||
Upon receiving SIGHUP, the python script will exit with status code 42. This
|
||||
can be used by a wrapper script to determine if the python script should be
|
||||
re-run. When a SIGINT or SIGTERM is received, the script exits with status
|
||||
code 0, possibly indicating a normal exit.
|
||||
|
||||
Example wrapper script:
|
||||
|
||||
#!/bin/sh
|
||||
STATUS=42
|
||||
while test $STATUS -eq 42; do
|
||||
python "$@" that_script_above.py
|
||||
STATUS=$?
|
||||
done
|
||||
|
||||
Example workers.properties (for mod_jk):
|
||||
|
||||
worker.list=foo
|
||||
worker.foo.port=8009
|
||||
worker.foo.host=localhost
|
||||
worker.foo.type=ajp13
|
||||
|
||||
Example httpd.conf (for mod_jk):
|
||||
|
||||
JkWorkersFile /path/to/workers.properties
|
||||
JkMount /* foo
|
||||
|
||||
Note that if you mount your ajp application anywhere but the root ("/"), you
|
||||
SHOULD specifiy scriptName to the WSGIServer constructor. This will ensure
|
||||
that SCRIPT_NAME/PATH_INFO are correctly deduced.

ajp - an AJP 1.3/WSGI gateway.

For more information about AJP and AJP connectors for your web server, see
|
||||
<http://jakarta.apache.org/tomcat/connectors-doc/>.
|
||||
|
||||
For more information about the Web Server Gateway Interface, see
|
||||
<http://www.python.org/peps/pep-0333.html>.
|
||||
|
||||
Example usage:
|
||||
|
||||
#!/usr/bin/env python
|
||||
import sys
|
||||
from myapplication import app # Assume app is your WSGI application object
|
||||
from ajp import WSGIServer
|
||||
ret = WSGIServer(app).run()
|
||||
sys.exit(ret and 42 or 0)
|
||||
|
||||
See the documentation for WSGIServer for more information.
|
||||
|
||||
About the bit of logic at the end:
|
||||
Upon receiving SIGHUP, the python script will exit with status code 42. This
|
||||
can be used by a wrapper script to determine if the python script should be
|
||||
re-run. When a SIGINT or SIGTERM is received, the script exits with status
|
||||
code 0, possibly indicating a normal exit.
|
||||
|
||||
Example wrapper script:
|
||||
|
||||
#!/bin/sh
|
||||
STATUS=42
|
||||
while test $STATUS -eq 42; do
|
||||
python "$@" that_script_above.py
|
||||
STATUS=$?
|
||||
done
|
||||
|
||||
Example workers.properties (for mod_jk):
|
||||
|
||||
worker.list=foo
|
||||
worker.foo.port=8009
|
||||
worker.foo.host=localhost
|
||||
worker.foo.type=ajp13
|
||||
|
||||
Example httpd.conf (for mod_jk):
|
||||
|
||||
JkWorkersFile /path/to/workers.properties
|
||||
JkMount /* foo
|
||||
|
||||
Note that if you mount your ajp application anywhere but the root ("/"), you
|
||||
SHOULD specifiy scriptName to the WSGIServer constructor. This will ensure
|
||||
that SCRIPT_NAME/PATH_INFO are correctly deduced.

scgi - an SCGI/WSGI gateway.
|
||||
|
||||
For more information about SCGI and mod_scgi for Apache1/Apache2, see
|
||||
<http://www.mems-exchange.org/software/scgi/>.
|
||||
|
||||
For more information about the Web Server Gateway Interface, see
|
||||
<http://www.python.org/peps/pep-0333.html>.
|
||||
|
||||
Example usage:
|
||||
|
||||
#!/usr/bin/env python
|
||||
import sys
|
||||
from myapplication import app # Assume app is your WSGI application object
|
||||
from scgi import WSGIServer
|
||||
ret = WSGIServer(app).run()
|
||||
sys.exit(ret and 42 or 0)
|
||||
|
||||
See the documentation for WSGIServer for more information.
|
||||
|
||||
About the bit of logic at the end:
|
||||
Upon receiving SIGHUP, the python script will exit with status code 42. This
|
||||
can be used by a wrapper script to determine if the python script should be
|
||||
re-run. When a SIGINT or SIGTERM is received, the script exits with status
|
||||
code 0, possibly indicating a normal exit.
|
||||
|
||||
Example wrapper script:
|
||||
|
||||
#!/bin/sh
|
||||
STATUS=42
|
||||
while test $STATUS -eq 42; do
|
||||
python "$@" that_script_above.py
|
||||
STATUS=$?
|
||||
done

This server is similar to SWAP <http://www.idyll.org/~t/www-tools/wsgi/>,
|
||||
another SCGI/WSGI server.
|
||||
|
||||
It differs from SWAP in that it isn't based on scgi.scgi_server and
|
||||
therefore, it allows me to implement concurrency using threads. (Also,
|
||||
this server was written from scratch and really has no other depedencies.)
|
||||
Which server to use really boils down to whether you want multithreading
|
||||
or forking. (But as an aside, I've found scgi.scgi_server's implementation
|
||||
of preforking to be quite superior. So if your application really doesn't
|
||||
mind running in multiple processes, go use SWAP. ;)

scgi - an SCGI/WSGI gateway.

For more information about SCGI and mod_scgi for Apache1/Apache2, see
|

<http://www.mems-exchange.org/software/scgi/>.
|

|

For more information about the Web Server Gateway Interface, see
|
||||
<http://www.python.org/peps/pep-0333.html>.

Example usage:

|

#!/usr/bin/env python

import sys

from myapplication import app # Assume app is your WSGI application object
|

ret = WSGIServer(app).run()

sys.exit(ret and 42 or 0)

|

See the documentation for WSGIServer for more information.
|
||||
|
||||
About the bit of logic at the end:
|
||||
Upon receiving SIGHUP, the python script will exit with status code 42. This
|
||||
can be used by a wrapper script to determine if the python script should be
|
||||
re-run. When a SIGINT or SIGTERM is received, the script exits with status
|
||||
code 0, possibly indicating a normal exit.
|
||||
|
||||
Example wrapper script:
|
||||
|
||||
#!/bin/sh
|
||||
STATUS=42
|
||||
while test $STATUS -eq 42; do
|
||||
python "$@" that_script_above.py

STATUS=$?

This server is similar to SWAP <http://www.idyll.org/~t/www-tools/wsgi/>,

another SCGI/WSGI server.

It differs from SWAP in that it isn't based on scgi.scgi_server and

therefore, it allows me to implement concurrency using threads. (Also,

this server was written from scratch and really has no other depedencies.)

Which server to use really boils down to whether you want multithreading
|

or forking. (But as an aside, I've found scgi.scgi_server's implementation
|

of preforking to be quite superior. So if your application really doesn't

mind running in multiple processes, go use SWAP. ;)

to your application. It is used to determine PATH_INFO (which doesn't

bindAddress is the address to bind to, which must be a string or

the umask is to be changed to before the socket is created in the
