Uwe Schindler commented on SOLR-11087:
--------------------------------------
Hi,
I think the issue here should focus to get rid on the web application and have
a single lib folder directly below the root dir of the distribution. Then we
have a solr-main.jar (without solrj) and this one also contains a Main.class to
bootstrap Jetty. This would make deployment much easier. As said before, the
tons of Java/Javascript should also be packaged into a JAR file to get rid of
tons of small files making unzipping damn slow and consume lots of space (block
size). Jetty is able to deliver static contents from a JAR file directy, I use
this all the time for microservice-like stuff.
Once we are at that place we could maybe split the root lib folder into 2 of
them: One with Solrj and one with the remaining stuff to startup the server.
The contrib modules can be linked into cores the usual way with {{<lib>}}.
If I would have some more time, I could start in refactoring all this, but my
knowledge with Solr is limited. I'd really like to get rid of
SolrDispatchFilter and replace it with a simple servlet directly added to the
root context in the Solr Bootstrap class.
About your comment: Hardlinks is a problem on Windows, and Symlinks are not
better. I'd not do this.

> Project: Solr
> Issue Type: Sub-task

> Priority: Major
> Fix For: 8.1, master (9.0)

> Attachments: SOLR-11087.patch

> Sub task of SOLR-6806
> The {{dist/}} folder contains many duplicate jar files, totalling 10,5M:
> {noformat}
> 4,6M ./dist/solr-core-6.6.0.jar (WEB-INF/lib)
> 1,2M ./dist/solr-solrj-6.6.0.jar (WEB-INF/lib)
> 4,7M ./dist/solrj-lib/* (WEB-INF/lib and server/lib/ext)
> {noformat}
> The rest of the files in dist/ are contrib jars and test-framework.
> To weed out the duplicates and save 10,5M, we can simply add a
> {{dist/README.md}} file listing what jar files are located where. The file
> could also contain a bash one-liner to copy them to the dist folder. Another
> possibility is to ship the binary release tarball with symlinks in the dist
> folder, and advise people to use {{cp -RL dist mydist}} which will make a
> copy with the real files. Downside is that this won't work for ZIP archives
> that do not preserve symlinks, and neither on Windows.
