Fergus McMenemie commented on SOLR-1060:
----------------------------------------
I am working on minor changes to the (now inappropriatly named) HttpDataSource
to allow it to access file:// based resources more cleanly. It should IMHO have
been called URIDataSource.
I am also rewriting ChangeListEntityProcessor to allow it to cooperate with a
child entity which is using either HttpDataSource or FileDataSource. This
cooperation will not be automatic, the person setting up the data-config.xml
will need to take account of which datasource the child is using when
configuring the parent ChangeListEntityProcessor. And of course IMHO ...
FileDataSource should actually have been called diskDataSource or
filesysDataSource:-)

> I have finished a new DIH EntityProcessor. It is designed around the idea
> that whatever demon is used to maintain your content store it is likely to
> drop a report or log file explaining what has changed within your content
> store. I wish to use this report file to control the indexing of the new or
> changed content and the removal of old content. The report files, perhaps
> from un-tar or un-zip, are likely to reference jpegs and directory stubs
> which need to be ignored. I assumed a file based content repository but this
> should be expanded to handle URI's as well
> I feel that the current FileListEntityProcessor is poorly named. It should be
> called the dirWalkEntityProcessor or dirCrawlEntityProcessor or such. And
> this new EntityProcessor should have the name FileListEntityProcessor.
> However what is done is done. I then came up with manifestEnityProcessor
> which I thought suited, manifest files are all over the content sets I deal
> with and the dictionary definition seemed close enough ("ships manifest").
> However how about ChangeListEntityProcessor
> {code}
> <entity name="jc"
> processor="ManifestEntityProcessor"
> baseDir="/Volumes/Techmore/ts/aaa/schema/data"
> rootEntity="false"
> dataSource="null"
> allowRegex="^.*\.xml$"
> blockRegex="usc2009"
> manifestFileName="/Volumes/ts/man-find.txt"
> docAddRegex=".*"

> {code}
> The new entity fields are as follows.
>
> *manifestFileName* is the required location of the manifest file. If this
> value is relative, it assumed to be relative to baseDir.
> *allowRegex* is an optional attribute that if present discards any line
> which does not match the regExp
>
> *blockRegex* is an optional attribute that is applied after any allowRegex
> and discards any line which matches the regExp
> *docAddRegex* is a required regex to identify lines which when matched
> should cause docs to be added to the index. As well as matching the line it
> should also return the portion of the line which contains the filepath as
> group(1)
> *docDeleteRegex* is an optional value of a regex to identify documents
> which when matched should be deleted from the index. As well as matching the
> line it should also return the portion of the line which contains the
> filepath as group(1) **PLANNED**
