Add into policy.xml?

[GilbertB]

For throttle and CPU limiting, I have

Code: Select all

<policy domain="resource" name="area" value="1GB"/>

Define arguments for the memory, map, area, and disk resources with
SI prefixes (.e.g 100MB). In addition, resource policies are maximums for
each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
exceeds policy maximum so memory limit is 1GB).
-->

<configure name="MAGICK_THROTTLE" value="100"/>
<configure name="MAGICK_THREAD_LIMIT" value="2"/>

<policymap>
<!-- <policy domain="system" name="precision" value="6"/> -->
<!-- <policy domain="resource" name="temporary-path" value="/tmp"/> -->
<!-- <policy domain="resource" name="memory" value="2GiB"/> -->
<!-- <policy domain="resource" name="map" value="4GiB"/> -->
<!-- <policy domain="resource" name="area" value="1GB"/> -->
<!-- <policy domain="resource" name="disk" value="16EB"/> -->
<!-- <policy domain="resource" name="file" value="768"/> -->
<!-- <policy domain="resource" name="thread" value="4"/> -->
<!-- <policy domain="resource" name="throttle" value="0"/> -->
<!-- <policy domain="resource" name="time" value="3600"/> -->
</policymap>

Q1- if the above format correct?
Q2- Do I need to reboot anything for it to take effect?

Thx!

Your file is incorrect. You should uncomment the following lines and set the values there:

Code: Select all

<policymap>
<!-- <policy domain="resource" name="thread" value="4"/> -->
<!-- <policy domain="resource" name="throttle" value="0"/> -->
</policymap>

Here is an example policy file we use:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE policymap [
<!ELEMENT policymap (policy)+>
<!ELEMENT policy (#PCDATA)>
<!ATTLIST policy domain (delegate|coder|filter|path|resource) #IMPLIED>
<!ATTLIST policy name CDATA #IMPLIED>
<!ATTLIST policy rights CDATA #IMPLIED>
<!ATTLIST policy pattern CDATA #IMPLIED>
<!ATTLIST policy value CDATA #IMPLIED>
]>

  Configure ImageMagick policies.

  Domains include system, delegate, coder, filter, path, or resource.

  Rights include none, read, write, and execute.  Use | to combine them,
  for example: "read | write" to permit read from, or write to, a path.

  Use a glob expression as a pattern.

  Suppose we do not want users to process MPEG video images:

    <policy domain="delegate" rights="none" pattern="mpeg:decode" />

  Here we do not want users reading images from HTTP:

    <policy domain="coder" rights="none" pattern="HTTP" />

  Lets prevent users from executing any image filters:

    <policy domain="filter" rights="none" pattern="*" />

  The /repository file system is restricted to read only.  We use a glob
  expression to match all paths that start with /repository:
  
    <policy domain="path" rights="read" pattern="/repository/*" />

  Any large image is cached to disk rather than memory:

    <policy domain="resource" name="area" value="1GB"/>

  Define arguments for the memory, map, area, and disk resources with
  SI prefixes (.e.g 100MB).  In addition, resource policies are maximums for
  each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
  exceeds policy maximum so memory limit is 1GB).
