From c6f091cc2348512e5a707cc9e0d8286b8e2ada0c Mon Sep 17 00:00:00 2001 From: Tomas Cohen Arazi Date: Fri, 31 May 2013 15:56:59 -0300 Subject: [PATCH] Bug 10733: Memcached on package installs This patch makes the koha-create script adjust the koha-conf.xml file with the proper string substitutions to enable the use of memcached for the created Koha instance. It adds three option switches that control this: --use-memcached (defaults to "no") --memcached-servers "host1:port1,..." (defaults to '127.0.0.1:11211') --memcached-prefix "desired_namespace prefix" (defaults to 'koha_') It respects the current schema configuration schema, where configuration values are pondered like this: hardcoded < koha-sites.conf < koha-create option switches koha-sites.conf is read for USE_MEMCACHED, MEMCACHED_SERVERS and MEMCACHED_PREFIX. Note: the docs discourage setting user's own namespace prefix. Using memcached is off as the default. The relevant configuration variables will remain empty if the user doesn't pass --use-memcached to the command. It matches the current behaviour. To test: - Apply the patch - Build your own packages and install them on a test server a) Create a new instance without using the new switches like: $ koha-create --create-db memctest - Check that /etc/koha/sites/memctest/koha-conf.xml contains: * Empty tag. * Empty tag. b) Play with the possible combination of option switches (Note that the code defaults to empty and will remain like that if --use-memcached is not used, so less tests...) $ koha-create --create-db --use-memcached memctest $ koha-create --create-db --use-memcached --memcached-servers "anything:xxx" memctest $ koha-create --create-db --use-memcached --memcached-servers "anything:xxx" --memcached-prefix "something" memctest $ koha-create --create-db --use-memcached --memcached-prefix "something" memctest - Check the koha-conf.xml and /etc/apache2/sites-enabled/memctest file reflect the chosen options. c) Run $ koha-create --help - It should advertise this addition accordingly. d) Run $ man koha-create - Man page for koha-create should provide good information on the new switches behaviour Sponsored-by: Universidad Nacional de Cordoba Signed-off-by: Mark Tompsett Signed-off-by: Robin Sheat Signed-off-by: Galen Charlton --- debian/docs/koha-create.xml | 46 ++++++++++ debian/scripts/koha-create | 114 +++++++++++++++++++++---- debian/templates/apache-site.conf.in | 4 + debian/templates/koha-conf-site.xml.in | 4 +- 4 files changed, 148 insertions(+), 20 deletions(-) diff --git a/debian/docs/koha-create.xml b/debian/docs/koha-create.xml index 6ac21719e9..99ce1914d2 100644 --- a/debian/docs/koha-create.xml +++ b/debian/docs/koha-create.xml @@ -29,6 +29,9 @@ en|es|fr|nb|ru|uk dom|grs1 dom|grs1 + + server:port + namespace_prefix /path/to/some.sql /path/to/config /path/to/passwd @@ -125,6 +128,27 @@ + + + + Make the Koha instance use memcached. . + + + + + + + Specify a comma-separated list of host:port memcached servers for using with the created Koha instance.
