1.1. 3.3.x Branch¶
1.1.1. Version 3.3.3¶
1.1.1.1. Features and Enhancements¶
#4623: Handle replicator instance start time during upgrades better.
#4653: Fix the ability to use
;
in config values.#4626: Fix purge infos replicating to the wrong shards during shard splitting.
#4669: Make it possible to override
[replicator] valid_socket_options
with more than two items.#4670: Allow setting of some ibrowse replication options such as
{prefer_ipv6, true}
.#4679: Fix multipart parser “attachment longer than expected” error. Previously there was a small chance attachments were not replicated.
#4680: Allow restarting failed shard splitting jobs.
#4722: Fix badmatch error when purge requests time out.
#4736: Stop client process and clean up if client disconnects when processing streaming requests.
#4758: Remove sensitive headers from the mochiweb request in process dictionary. This should prevent sensitive headers leaking into logs when a request process crashes.
#4784: Extract the correct node name from
ERL_FLAGS
inremsh
.#4794: Fix incorrect raising of
database_does_not_exist
error.#4821: Wait for compacted indexes to flip. Previously, a timeout during compact file flips could lead to crashes and a subsequent recompaction.
#4837: Fix update bug in ets_lru.
#4847: Require auth for
_replicate
endpoint.#4878: Add an option to scrub some sensitive headers from external json requests.
1.1.2. Version 3.3.2¶
1.1.2.1. Features and Enhancements¶
#4529: In Javascript process manager, use a database tag in addition to a ddoc ID to quickly find processes. This should improve performance.
#4473: Avoid re-compiling filter view functions. This could speed up Javascript filter functions.
#4412: Remove Javascript json2 script and the try/except clause around seal.
#4513: Allow configurable timeouts for
_view
and_search
. Search timeouts can be specified as[fabric] search_timeout
and[fabric] search_permsg
. View per-message timeout can be configured as[fabric] view_permsg_timeout
.#4438: Proxy auth can now use one of the configured hash algorithms from chttpd_auth/hash_algorithms to decode authentication tokens.
#4370: Ensure design docs are uploaded individually when replicating with
_bulk_get
. This restores previous behavior before version 3.3.0.#4416: Allow
_local
doc writes to the replicator dbs. Previously this issue prevented replicating the replicator db itself, since checkpointing was not working properly.#4363: Fix replication
_scheduler/docs
"total_rows"
value.#4380: Be more defensive about SpiderMonkey location. An error should be emitted early if the Spidermonkey library cannot be found.
#4388: Bump recon to 2.5.3. See the changelog for more details.
#4476, #4515, #4490, #4350, #4379: Various documentation cleanups and fixes.
Fix for CVE-2023-26268.
1.1.3. Version 3.3.1¶
1.1.3.1. Features and Enhancements¶
#4343, #4344, #4345: Fix
undef
when parsing replication doc body with auser_ctx
.#4346: Add
make
target to findundef
errors.#4347: Remove failed
couch_plugins
experiment, fixes moreundef
errors.#4348: Fix
undef
error inweatherreport
.#4353: Allow starting of more than one replication job. (D’OH!)
1.1.4. Version 3.3.0¶
1.1.4.1. Highlights¶
#4308: Replicator was optimized and should be faster. It now uses the _bulk_get endpoint on the source, and can statistically skip calling _revs_diff on the target. Benchmark tests replicating 1M documents, 10KB each, from UK to US East show a 3x speed improvement.

1.1.4.2. Features and Enhancements¶
#3766, #3970, #3972, #4093, #4102, #4104, #4110, #4111, #4114, #4245, #4246:, #4266: Add
smoosh
queue persistence. This allows resumingsmoosh
operations after a node restart. This is disabled by default and can be enabled with[smoosh] persist = true
. Optimisesmoosh
operations and increase test coverage to 90%.#3798: Add
libicu
version and collation algorithm version to/_node/{node-name}/_versions
.#3837: The Erlang source tree is now auto-formatted with
erlfmt
.#3845: Clean up the
couch_ejson_compare
C-module and squash Microsoft compiler warnings.#3832: Add
GET
variant to_dbs_info
endpoint, used to bePOST
only.#3864: Improve
erlang_ls
configuration.#3853: Remove legacy
ddoc_cache_opener
gen_server
and speed up event routing.#3879: Remove use of
ERL_OPTS
environment variable. All supported Erlang versions now useERL_COMPILER_OPTIONS
for the same purpose.#3883: Add support for SpiderMonkey 91.
#3889: Track
libicu
collator versions in the view header.#3952: Make the timeout for receiving requests from attachment writers configurable.
#3927: Include index signature in
_search_info
.#3963: Optimtize key tree stemming by using maps instead of sets. This greatly reduced memory usage for heavily conflicted docs in some situations.
#3974: Create new config options in
[couchdb]
and[smoosh]
sections to enable finer control of compaction logging levels.#3983, #3984, #3985, #3987, #4033: Add various functions to
couch_debug
module.#4000: Ensure
Object.prototype.toSource()
is always available.#4018: Update
jiffy
to 1.1.1 andb64url
to 1.0.3.#4021: Reduce smoosh compaction log level to
debug
.#4041: Allow and evaluate nested json claim roles in JWT token.
#4064: Enable replicating purge requests between nodes. Also avoid applying interactive purges more than once.
#4069, #4084: Drop support for Erlang < 23, update
vm.args
settings to match. Review this if you have customized yourvm.args
.#4083: Support Elixir 13.
#4085: Add an option to let
custodian
always use[cluster] n
value.#4095: Implement
winning_revs_only
option for the replicator. It replicates only the winning revisions from the source to the target, effectively discarding conflicts.#4135: Separate search IO from file IO.
#4140, #4162: Upgrade hash algorithm for cookie auth (sha1 -> sha256). This introduces a new config setting
hash_algorithms
. New cookie values are hashed with sha256, sha1 hashes are still accepted. Admins can set this to sha256 only. Sha1 will be disallowed in the next major release. Show supported hash algorithms in/_node/{node-name}/_versions
endpoint.#4179: Don’t double-encode changes sequence strings in the replicator.
#4182: Explicitly maintain a fully connected cluster. Previously, it was possible for the nodes to disconnect, and for that state to persist until the nodes restarted.
#4198: Redact passwords in log file.
#4243: Update
mochiweb
to 3.1.1.#4254: The
_dbs_info
access control is now configured with the[couchdb] admin_only_all_dbs
setting. Defaults to true. This was a leftover from the 3.0.0 release.#4264:
active
database sizes is now limited to leaf nodes. Previously, it included intermediate tree nodes, which had the effect that deleting (large) documents did not decreaseactive
database size. In addition,smoosh
now picks up databases where large documents are deleted for compaction more eagerly, reclaiming the deleted space quicker.#4270: Shard splitting now uses its own
reshard
IO priority. It can be configured to be safely run in the background with production loads, or with maximum IO available, if admins prefer quicker progress.#4274: Improve validation of replicator job parameters & move
_replicator
VDU design doc to internal BDU.#4280: Add
CFLAGS
andLDFLAGS
to ICU build parameters.#4284: Remove all usage of global to avoid potential deadlocks in replication jobs.
#4287: Allow
=
in config key names.#4306: Fauxton was updated to version v1.2.9. Changes since v1.2.8 can be found here
#4317: Write “Relax” welcome message to standard out on Windows.
1.1.4.3. Performance¶
#3860: Add sharding to
couch_index_server
, similar to #3366, avoids processing bottlenecks on servers with a lot of concurrent view indexing going on.#3891: Avoid decoding JWT payloads when not necessary.
#4031: Default
[rexi] use_kill_all
totrue
. This improves intra-cluster-node messaging. Set to false if you run a cluster with nodes that have a version <3.0.0.#4052: Optimise
couch_util:reorder_results/2,3
, which speeds up_bulk_docs
and_revs_diff
.#4055: Avoid using
length/1
guard for>0
or==0
tests incouch_key_tree
.#4056: Optimise
couch_key_tree:find_missing/2
. This speeds up_revs_diff
.#4059: Reduce complexity of
possible_ancestors
from quadratic to linear. This speeds up working with heavily conflicted documents significantly.#4091: Optimise
couch_util:to_hex/1
, this speeds up all operations that need to encode a revision id into JSON (this is most operations).#4106: Set
io_priority
in all IO paths. Introducessystem
io_priority
.#4144, #4172: Implement
_bulk_get
support for the replicator. Backward compatibility is ensured. This speeds up all replications. Add option to disable new behaviour for legacy setups.#4163: Statistically skip
_revs_diff
in the replicator. This improves performance for replications into empty targets.#4177: Remove the long deprecated
bigcouch 0.4
change sequence support.#4238: Optimise
_bulk_get
endpoint. This speeds up replication of 1M docs by ~2x. Individual_bulk_get
requests are up to 8x faster.#3517: Add experimental fix for reduce performance regression due to expensive repeated AST-transformations on newer SpiderMonkey versions. Set
COUCHDB_QUERY_SERVER_JAVASCRIPT
env var toCOUCHDB_QUERY_SERVER_JAVASCRIPT="/opt/couchdb/bin/couchjs /opt/couchdb/share/server/main-ast-bypass.js"
.#4262:
couchjs
executable built against Spidermonkey >= 78 will return the detailedmajor.minor.patch
as opposed to just themajor
version as previously.
