Matthew Biscocho commented on SOLR-16470:
-----------------------------------------
[~gerlowskija] Started to look into the filecontent API and noticed it was
failing with a stack trace. Doing some digging, I believe I found a regression
due to this [commit.|https://github.com/apache/solr/pull/1867] Don't fully
understand what this does yet but was probably not caught because there are no
tests around the filecontent command on this replication API. This will
probably need a fix before migrating this API over to V2

> Create V2 equivalent of V1 Replication: Get IndexVersion, Get FileStream, Get
> File List
> ---------------------------------------------------------------------------------------
>
> Key: SOLR-16470
> URL: https://issues.apache.org/jira/browse/SOLR-16470
> Project: Solr
> Issue Type: Sub-task
> Components: v2 API
> Affects Versions: 9.2
> Reporter: Sanjay Dutt
> Priority: Major
> Labels: V2, newdev
> Time Spent: 4h 20m
> Remaining Estimate: 0h
>
> Replication Handler has no v2 equivalent. This ticket is covering few
> endpoints from ReplicationHandler such as Get IndexVersion, Get FileStream,
> Get File List.
> Existing V1
> |-GET /solr/collName/replication?command=indexversion-|
> |GET /solr/collName/replication?command=filecontent|
> |-GET /solr/collName/replication?command=filelist-|
> Proposed API design
> |-GET /api/cores/coreName/replication/indexversion-|
> |GET /api/cores/coreName/replication/files/filePath|
> |-GET /api/cores/coreName/replication/files-|
> few other pointers that might be helpful, especially for newcomers:
> * The v1 logic for this API lives in ReplicationHandler
> * [Some discussion of how APIs work in Solr (Particularly the "APIs in Solr"
> section.)|https://github.com/apache/solr/blob/main/dev-docs/apis.adoc#apis-in-solr]
> * [A step-by-step guide to creating APIs using the preferred v2 API
> framework|https://github.com/apache/solr/blob/main/dev-docs/apis.adoc#writing-jax-rs-apis]
> * [A recent PR that adds a v2 API, as an
> example|https://github.com/apache/solr/pull/2144]
