We have deployed a new n98-magerun version with only one new command but many improvements which makes the
tool more stable in daily usage.

New features/optimizations

Disable root warning

It’s now possible to supress the “It’s not recommended to run n98-magerun as root user” warning.
This can be useful i.e. during a deployment which runs as root-user. In this case you can create
a system wide config on the remote host in file “/etc/n98-magerun.yaml” with this content:

application:
  check-root-user: false

application:

check-root-user: false

#332 make WARNING_ROOT_USER configurable/optional (by Christian Münch)

Remove setup resources

Removes the entry for one or all module resource setups. This command is useful if you want to re-run an install
script again possibly due to debugging. Alternatively you would have to remove the row from the database manually.

$&gt; n98-magerun.phar sys:setup:remove ACME_Module

1 2	$> n98-magerun.phar sys:setup:remove ACME_Module

#392 Add remove setup resource command (by Aydin Hassan)

Create dummy users with addresses

A new option was added to the customer:create:dummy command which allows automatic address creation.

$&gt; n98-magerun.phar customer:create:dummy --with-addresses 10 en_US

1 2	$> n98-magerun.phar customer:create:dummy --with-addresses 10 en_US

#397 Added option to create dummy customer with an address (by Gilles Doge)

Better observer list

A new event area “crontab” was added. All events are now sorted and the type of the observer is visible in the table.

#413 Enhanced dev:module:observer:list (by Cyrill Schumacher)

Improvements

#387 Unlink sym-linked folders instead of recursively removing (by Aydin Hassan)
#390 Some documentation updates (by Aydin Hassan)
#391 Fixed broken filters in dev:module:list command (by Tjerk Ameel)
#393 Optimize failing on long lines (by Alexander Menk)
#400 Added adminhtml_cache_refresh_type event (by Marc Päpper)
#403 Sys setup incremental tiny fixes (by Cyrill Schumacher)
#407 Check for Enterprise_PageCache presence before using it (by Vinai Kopp)

Other updates and fixes

Changed db:dump strip settings (by Alexander Menk)
Updated 3rd party components (Symfony, PHPUnit, Twig)

Please update to the latest version by:

$&gt; n98-magerun.phar self-update

1 2	$> n98-magerun.phar self-update

I hope the new version let you more efficient in the daily work with Magento. Have fun!

Cache Backend Benchmarking with n98-magerun

2 Comments on Cache Backend Benchmarking with n98-magerun

This is the start of a series which presents 3rd party n98-magerun modules.

The first one is a module which helps you to benchmark your shop cache system.

It’s a port of a benchmark script by Colin Mollenhour
which was a fork of a symlink cache script by Vinai Kopp.

Installation

The installation is really strait forward:

 mkdir -p ~/.n98-magerun/modules
 cd ~/.n98-magerun/modules
 git clone https://github.com/cmuench/magerun-module-cache-benchmark.git

mkdir -p ~/.n98-magerun/modules

cd ~/.n98-magerun/modules

git clone https://github.com/cmuench/magerun-module-cache-benchmark.git

Usage

After the installation you should see some new cache commands in your n98-magerun command list.

 cache:benchmark:analyse     Analyze the current cache contents.
 cache:benchmark:clean       Flushes cache backend.
 cache:benchmark:comp_test   Test compression library performance
 cache:benchmark:init        Inits cache dataset
 cache:benchmark:load        Load an existing dataset.
 cache:benchmark:ops         Execute a pre-generated set of operations on the existing cache.
 cache:benchmark:tags        Benchmark getIdsMatchingTags method.

cache:benchmark:analyse Analyze the current cache contents.

cache:benchmark:clean Flushes cache backend.

cache:benchmark:comp_test Test compression library performance

cache:benchmark:init Inits cache dataset

cache:benchmark:load Load an existing dataset.

cache:benchmark:ops Execute a pre-generated set of operations on the existing cache.

cache:benchmark:tags Benchmark getIdsMatchingTags method.

First run “cache:benchmark:init” which generates cache entries.
The init command can has a lot of paramters.

--name                (default to default) (default: "default")
--keys                Number of cache keys (default to 10000) (default: 10000)
--tags                Number of cache tags (default to 2000) (default: 2000)
--min-tags            The min number of tags to use for each record (default 0) (default: 0)
--max-tags            The max number of tags to use for each record (default 0) (default: 15)
--min-rec-size        The smallest size for a record (default 1) (default: 1)
--max-rec-size        The largest size for a record (default 1) (default: 1024)
--clients             The number of clients for multi-threaded testing (defaults to 4) (default: 4)
--ops                 The number of operations per client (defaults to 10000) (default: 10000)
--write-chance        The chance-factor that a key will be overwritten (defaults to 1000) (default: 1000)
--clean-chance        The chance-factor that a tag will be cleaned (defaults to 5000) (default: 5000)
--seed                The random number generator seed (default random)
--help (-h)           Display this help message.
--quiet (-q)          Do not output any message.
--verbose (-v|vv|vvv) Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug
--version (-V)        Display this application version.
--ansi                Force ANSI output.
--no-ansi             Disable ANSI output.
--no-interaction (-n) Do not ask any interactive question.
--root-dir            Force magento root dir. No auto detection
--skip-config         Do not load any custom config.

--name (default to default) (default: "default")

--keys Number of cache keys (default to 10000) (default: 10000)

--tags Number of cache tags (default to 2000) (default: 2000)

--min-tags The min number of tags to use for each record (default 0) (default: 0)

--max-tags The max number of tags to use for each record (default 0) (default: 15)

--min-rec-size The smallest size for a record (default 1) (default: 1)

--max-rec-size The largest size for a record (default 1) (default: 1024)

--clients The number of clients for multi-threaded testing (defaults to 4) (default: 4)

--ops The number of operations per client (defaults to 10000) (default: 10000)

--write-chance The chance-factor that a key will be overwritten (defaults to 1000) (default: 1000)

--clean-chance The chance-factor that a tag will be cleaned (defaults to 5000) (default: 5000)

--seed The random number generator seed (default random)

--help (-h) Display this help message.

--quiet (-q) Do not output any message.

--verbose (-v|vv|vvv) Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug

--version (-V) Display this application version.

--ansi Force ANSI output.

--no-ansi Disable ANSI output.

--no-interaction (-n) Do not ask any interactive question.

--root-dir Force magento root dir. No auto detection

--skip-config Do not load any custom config.

No panic. The command defines default values for every setting.

After the generation you should see a bash script like “bash var/cachebench/default/run.sh” which was
generated by the init command.

Run the shell script an see the your benchmark statistics.
Now you are able to compare different cache backends (change it in your app/etc/local.xml config).
