----------------------------------------
Summary: Allow Multiple Regex Replacements On Upgrades
Key: AMBARI-23745
URL: https://issues.apache.org/jira/browse/AMBARI-23745
Project: Ambari
Issue Type: Task
Affects Versions: 2.7.0
Reporter: Jonathan Hurley
Assignee: Jonathan Hurley
Fix For: 2.7.0
When upgrading from one stack to another, the {{regex-replace}} key can be used
to find and replace a block of text which matches a given regular expression.
This works by finding the literal string matching the regex and turning this
into a regular find/replace.
For example:
{code}
<regex-replace find="\d-foo-\d" replace=""/>
{code}
on
{code}
1-foo-1
2-foo-2
3-foo-3
{code}
Would produce:
{code}
2-foo-2
3-foo-3
{code}
In order to replace all of the possible matches, we can extend the XSD of
{{RegexReplace}} to create multiple literal {{Replace}} instances for every
match.
