1.2. 3.1.x Branch

#3102, , #2877, : When a client disconnects unexpectedly, CouchDB will no longer log a “” error. Bring forth the rainbows.

#3109: Drilldown parameters for text index searches may now be specified as a list of lists, to avoid having to define this redundantly in a single query. (Some languages don’t have this facility.)
: The new [chttpd] buffer_response option can be enabled to delay the start of a response until the end has been calculated. This increases memory usage, but simplifies client error handling as it eliminates the possibility that a response may be deliberately terminated midway through, due to a timeout. This config value may be changed at runtime, without impacting any in-flight responses.

: The replicator now correctly picks jobs to restart during rescheduling, where previously with high load it may have failed to try to restart crashed jobs.
#2981: When handling extremely large documents (≥50MB), CouchDB can no longer time out on a gen_server:call if bypassing the IOQ.
: CouchDB will no longer fail to compact databases if it finds files from a 2.x compaction process (prior to an upgrade) on disk.
#2955 CouchDB now sends the correct CSP header to ensure Fauxton operates correctly with newer browsers.
, #3080: The couch_index server won’t crash and log errors if a design document is deleted while that index is building, or when a ddoc is added immediately after database creation.
: CouchDB now checks for and complains correctly about invalid parameters on database creation.
#2953: Some parameters not allowed for text-index queries on partitioned database are now properly validated and rejected.
: Text-based search indexes may now be cleaned up correctly, even if the design document is now invalid.
#3121: fips is now only reported in the welcome message if FIPS mode was enabled at boot (such as in vm.args).
: Using COPY to copy a document will no longer return a JSON result with two fields.
: Malformed URLs in replication requests or documents will no longer throw an error.

JS tests skip faster now.
More JS tests ported into elixir: reader_acl, reduce_builtin, reduce_false, rev_stemming, update_documents, , view_compaction, all the view_multi_key tests, view_sandboxing, view_update_seq.

: CouchDB now supports linking against SpiderMonkey 68, the current Mozilla SpiderMonkey ESR release. This provides direct support for packaging on the latest operating system variants, including Ubuntu 20.04 “Focal Fossa.”
