mongo-c-driver 1.15.0
I'm pleased to announce version 1.15.0 of libbson and libmongoc,
the libraries constituting the MongoDB C Driver.
libbson
No change since 1.14.1; released to keep pace with libmongoc's version.
libmongoc
It is my pleasure to announce the MongoDB C Driver 1.15.0. This release adds
support for MongoDB 4.2 features.
Features:
Support for sharded transactions on MongoDB sharded clusters 4.2+.
Add convenient transaction runner (mongoc_client_session_with_transaction),
which accepts a callback and performs appropriate retry logic.
Add a new transaction option to specify maximum time to wait for a commit,
mongoc_transaction_opts_set_max_commit_time_ms.
Add URI option "retryReads=true" safely and automatically retries certain
read operations if the server is a MongoDB 3.6+. Note, this may require applications to adjust any custom retry logic to prevent inadvertently retrying for too long
Poll SRV records to mongos servers periodically.
Keep connections alive after a primary stepdown detected.
Standardizes URI options supported across all spec-compliant MongoDB drivers.
"retryWrites" URI option now defaults to true (requires crypto for session
support).
Send any aggregate with $out or $merge stage to a primary.
Add the ability to specify an aggregate pipeline as an update document.
Add a database aggregate helper, mongoc_database_aggregate.
Add option for change streams, "startAfter".
Add mongoc_change_stream_get_resume_token, which returns the resume token
which should be used to resume a change stream.
Add support for zstd compression.
Bug fixes:
Correctly report an error in mongoc_change_stream_next if the resume token
(_id) is not a document. Previously, an error was only reported if the
field was missing.
Fix mongoc_collection_update with MONGOC_UPDATE_MULTI_UPDATE,
mongoc_collection_remove, and mongoc_collection_delete when retryWrites
was enabled. They would fail previously.
Command options are now correctly taken into account when batching bulk
writes for OP_QUERY. It was possible to exceed the maximum document size
before.
Fix a crash if a multi-batch bulk write with OP_MSG errored on a batch.
mongo-c-driver 1.14.0
=====================
It is my pleasure to announce the MongoDB C Driver 1.14.0.
Features:
* Support for OpenSSL 1.1.1 and its implementation of TLS v1.3.
* New function mongoc_stream_should_retry.
* New accessor mongoc_server_description_last_update_time.
* New method mongoc_client_reset to be called after forking.
Bug fixes:
* OP_MSG with unacknowledged writes (write concern of w:0) would serialize
incorrectly on big-endian platforms, causing writes to use the default
write concern of w:1.
* mongoc_collection_update_many and mongoc_collection_delete_many would fail
with the URI option retryWrites=true.
* In a transaction, the driver now properly ignores the readConcern configured
on a client, database, or collection: only the mongoc_transaction_opt_t's
readConcern is used.
* Remove timestamp from uninstall scripts to permit reproducible build.
* Setting mongoc_ssl_opt_t.pem_file or ca_file to a bad file path caused a
hang with Darwin SSL.
* Fix the ENABLE_SASL cmake option:
* Remove unnecessary GSSAPI value. It was equivalent to specifying ENABLE_SASL=CYRUS.
* ENABLE_SASL=AUTO now correctly chooses SSPI on Windows instead of CYRUS.
* The client pool failed to set proper apm callbacks for clients created
via try_pop().
mongo-c-driver 1.13.1
=====================
It is my pleasure to announce the MongoDB C Driver 1.13.1.
Bug fixes:
* mongoc_collection_update_many and mongoc_collection_delete_many would fail
with the URI option retryWrites=true.
* Remove timestamp from uninstall scripts to permit reproducible build.
* Add missing header files to the release tarball to fix compilation when
configuring with ENABLE_SASL=GSSAPI.
* Separate libmongoc and libbson uninstall scripts so they do not overwrite
each other.
* Fix running make install with DESTDIR.
mongo-c-driver 1.13.0
=====================
It is my pleasure to announce the MongoDB C Driver 1.13.0.
Features:
* Report a new error code, MONGOC_ERROR_GRIDFS_CORRUPT, when a chunk larger
than chunkSize is detected. Before, the driver had crashed with an assert.
* Restructure of install directory. All mongoc headers are under mongoc/
and all bson headers are under bson/. The preferred way of including the
headers are mongoc/mongoc.h and bson/bson.h respectively.
Forwarding headers in the root are provided for backwards compatibility.
* The default CMake build type had been unspecified, now it is RelWithDebInfo.
* Support LibreSSL 2.7+.
Bug fixes:
* mongoc_collection_replace_one is now a correctly exported symbol.
* Fix multiple issues with readConcern and writeConcern inheritance.
* Fix rare crash with mongodb+srv URIs on Windows.
* mongoc_gridfs_create_file_from_stream ignored errors while writing chunks
to the server.
* The following functions should not have taken a "bypassDocumentValidation"
option in bson_t *opts, the option is now prohibited:
- mongoc_bulk_operation_insert_with_opts
- mongoc_bulk_operation_update_one_with_opts
- mongoc_bulk_operation_update_many_with_opts
- mongoc_bulk_operation_replace_one_with_opts
* The heartbeat-succeeded and heartbeat-failed events (part of SDAM
Monitoring) had uninitialized "duration" fields, they are now set correctly.
mongo-c-driver 1.12.0
=====================
It is my pleasure to announce the MongoDB C Driver 1.12.0.
Features:
* New function mongoc_client_session_in_transaction to check if a multi-
document transaction is started.

migrating from mongoc_collection_count to mongoc_collection_count_documents
Bug fixes:
* Fix occasional crash in sharded queries
* Retry all retryable write concern errors
* mongoc_client_session_commit_transaction sets the correct error label when
the primary is unavailable
* mongoc_collection_find_with_opts had prohibited read preference "primary"
in a transaction
* mongoc_collection_aggregate had not inherited its mongoc_collection_t's
read preference; only an explicitly provided read preference was used.
* Allow unencoded delimiters in username/password if unambiguous
mongo-c-driver 1.11.0
=====================
It is my pleasure to announce the MongoDB C Driver 1.11.0. This release adds
support for MongoDB 4.0 features. It includes the following additions and
improvements:
* Multi-document transactions, see mongoc_client_session_start_transaction
* New function mongoc_error_has_label to check for specific error labels such
as "TransientTransactionError" or "UnknownTransactionCommitResult" in
error replies.
* New functions to subscribe to changes on an entire client or database:
- mongoc_client_watch
- mongoc_database_watch
* New option for change streams, "startAtOperationTime".
* mongoc_collection_count_with_opts is deprecated for two new functions:
- mongoc_collection_count_documents
- mongoc_collection_estimated_document_count
* Support for SCRAM-SHA-256 authentication, including support for non-ASCII
passwords using libicu is an optional dependency.
* Faster mongoc_database_get_collection_names_with_opts fetches only names,
not the entire collection metadata.
Additional changes not specific to MongoDB 4.0:
* All "destroy" functions such as mongoc_collection_destroy now ignore a NULL
argument.
* The driver now returns an error if you attempt to use "arrayFilters" in an
update with a MongoDB server older than 3.6.
* Update functions include a new "upsertedCount" field in the reply document.
* Replace MD5 with FNV-1a hash to generate ObjectIds (for FIPS compliance).
Bug fixes:
* Functions incorrectly marked with the "const" compiler attribute are now
marked as "pure", fixes build error when link-time optimization is enabled.
mongo-c-driver 1.10.3
=====================
No change since 1.10.2; released to keep pace with libbson's version.
mongo-c-driver 1.10.2
=====================
It is my pleasure to announce the MongoDB C Driver 1.10.2. This release fixes
the libbson and libmongoc installed library filenames and SONAMEs on Linux.
They had changed unintentionally with the switch to CMake in 1.10.0; they are
now consistent with 1.9.x and previous releases. Thanks to Roberto C. Sánchez
for the fix.
mongo-c-driver 1.10.1
=====================
It is my pleasure to announce the MongoDB C Driver 1.10.1. This release fixes
the following bugs introduced in version 1.10.0:
* Client sessions were not prohibited with unacknowledged write concern and
mongoc_bulk_operation_execute; now they are prohibited. Client sessions have
been prohibited with all other unacknowledged writes since 1.10.
* The "arrayFilters" update option, new in MongoDB 3.6 and supported since
libmongoc 1.9.0, was inadvertently prohibited by
mongoc_bulk_operation_update_one_with_opts and
mongoc_bulk_operation_update_many_with_opts in 1.10. The option is now
permitted again.
* The mongoc-stat tool for displaying shared counters was disabled on Linux
and not installed; it is now restored.
mongo-c-driver 1.10.0
=====================
It is my pleasure to announce MongoDB C Driver 1.10.0. This version drops
support for MongoDB 2.6 and adds the following features and bugfixes:
* libbson and libmongoc are now maintained in the mongo-c-driver repository,
although they are still built as separate libraries, and libbson can still
be used without libmongoc.
* Building libbson and libmongoc now requires CMake on all platforms. The
Autotools build scripts ("configure" and related scripts) have been deleted.
See the "installing" page for updated instructions, including the new
ENABLE_MONGOC option and changes to the ENABLE_BSON option.
* IPv6 is now fully supported and conforms to RFC-6555. If a hostname has both
IPv4 and IPv6 DNS records, the driver tries connecting with IPv6 first. If a
connection can't be established after 250ms then IPv4 is tried in parallel.
Whichever succeeds connection first cancels the other. The successful DNS
result is cached for 10 minutes.
* If CMake is configured with ENABLE_SSL=AUTO (the default), libmongoc now
uses native TLS libraries on Mac and Windows, and OpenSSL everywhere else.
Before, it would search for OpenSSL on all platforms and only use native
TLS on Mac and Windows as a fallback.
* The driver now handshakes SSL connections to multiple servers in a replica
set or sharded cluster in parallel, so long as it uses OpenSSL or Windows
SChannel. (SSL handshakes with Apple's Secure Transport are still serial.)
A larger receive buffer with SChannel increases performance over slow
connections.
* All functions that accept read concern now prohibit it, if MongoDB is too
old to support it (MongoDB 3.0).
* Client sessions are now prohibited with unacknowledged writes.
* mongoc_collection_find_and_modify_with_opts now prohibits write concern if
MongoDB is too old to support it (MongoDB 3.0).
* Other helper functions for commands that write, now prohibit write concern
if MongoDB is too old to support it (pre-3.4):
mongoc_client_read_write_command_with_opts
mongoc_client_write_command_with_opts
mongoc_collection_read_write_command_with_opts
mongoc_collection_write_command_with_opts
mongoc_database_read_write_command_with_opts
mongoc_database_write_command_with_opts
mongoc_collection_aggregate with $out
mongoc_collection_drop_index_with_opts
mongoc_collection_drop_with_opts
mongoc_collection_rename_with_opts
mongoc_database_drop_with_opts
Write concern behavior is unchanged for regular CRUD functions.
* Setting a negative writeConcern level of -2 or smaller, via the "opts"
parameter to functions that accept BSON options, is now prohibited. The
special "w" values -2 through -4 are only used internally. The deprecated
"w=-1" is still allowed, as a synonym for "w=0".
* The Kerberos URI option authMechanismProperties=CANONICALIZE_HOST_NAME:true
is now implemented with the Windows Kerberos provider, SSPI.
* This repository now includes GDB and LLDB customizations for pretty-printing
bson_t structs as JSON while debugging. See the "debugging" page.
* The internal preprocessor symbol HAVE_STRINGS_H has been renamed
BSON_HAVE_STRINGS_H. If you maintain a handwritten bson-config.h you must
rename this symbol.
* The following helper functions do not work with mongoc_client_session_t,
they are deprecated in favor of running MongoDB commands directly with a
function like mongoc_client_read_command_with_opts:
mongoc_client_get_server_status
mongoc_collection_stats
mongoc_collection_validate
* mongoc_cursor_is_alive is now deprecated for mongoc_cursor_more, which is
functionally equivalent.
- New change streams API functions were not marked extern "C"
- mongoc_collection_watch now accepts a pipeline argument as a BSON
array, in addition to accepting a BSON document with a "pipeline"
array field

This version drops support for MongoDB 2.4 and adds support
for MongoDB 3.6 features:
- New struct mongoc_change_stream_t to watch a collection for changes.
- New struct mongoc_client_session_t represents a MongoDB 3.6 session,
which supports causal consistency: you are guaranteed to read your writes
and to perform monotonic reads, even when reading from secondaries or in
a sharded cluster.
- New functions that accept flexible options as a BSON document. These
accept a "sessionId" option and any future options. In addition, the
two new "update" functions accept the "arrayFilters" option that is new
in MongoDB 3.6:
- mongoc_collection_insert_one
- mongoc_collection_insert_many
- mongoc_collection_update_one
- mongoc_collection_update_many
- mongoc_collection_replace_one
- mongoc_collection_delete_one
- mongoc_collection_delete_many
- mongoc_client_command_with_opts
- mongoc_database_command_with_opts
- mongoc_collection_command_with_opts
- mongoc_client_find_databases_with_opts
- mongoc_client_get_database_names_with_opts
- mongoc_collection_create_bulk_operation_with_opts

- New URI option "retryWrites=true" safely and automatically retries certain
write operations if the server is a MongoDB 3.6 replica set or sharded
cluster.
- Support for MongoDB OP_MSG wire protocol.
Additional changes not specific to MongoDB 3.6:
- Support for mongodb+srv URIs to query DNS for SRV and TXT records that
configure the connection to MongoDB.
- Support LibreSSL with CMake build
- The "minPoolSize" URI option is deprecated: it's confusing and not useful.
Bug fixes:
- mongoc_bulk_operation_execute did not always initialize "reply".
- Fix C99 pedantic warnings.
- Remove option to bundle the Snappy compression library, it caused issues
for programs linking to libmongoc

- The internal mongoc_server_description_t struct is properly reinitialized
after a network error.
- Fix the encoding of this NEWS file.
- The zLib and Snappy compression libraries are bundled if not
available.

"read_prefs" parameter.
- mongoc_collection_create_index and
mongoc_collection_create_index_with_opts
are both now deprecated. Use mongoc_database_write_command_with_opts
instead; a guide to creating an index using that function has been
added.
- Use select, not WSAPoll, on Windows.
- Always mark a server "Unknown" after a network error (besides a
timeout).
- mongoc_client_pool_t sends platform metadata to the server; before,
only a single mongoc_client_t did.
- New stream method mongoc_stream_timed_out.
- Wire version checks introduced in 1.8.0 will prevent the driver from
connecting to a future MongoDB server version if its wire protocol is
incompatible.
- New CMake option ENABLE_MAINTAINER_FLAGS.
- CMake build now installs .pc files for programs that link to
libmongoc using pkg-config.
- New CMake option ENABLE_STATIC can be ON, OFF, or AUTO (the default)
- Minimum required CMake version has been increased to 3.1.
- Support for wire compression.
- Support for snappy and zlib. MongoDB 3.4 only supports snappy,
while zlib support is expected in MongoDB 3.6.
- New functions: mongoc_uri_get_compressors &
mongoc_uri_set_compressors, to get and set compressor
configuration on mongoc_uri_t
- Added support for comma seperated "compressors" connection string
option (e.g. mongodb://localhost/?compressors=snappy,zlib)

url encoded
- Unsupported connection string options now issue warnings
- Boolean values can now be represented as true/yes/y/t/1 and
false/no/n/f/0.
- Case is now preserved in Unix domain paths.
- New function mongoc_cursor_error_document provides access to
server's error reply if a query or command fails.
- New function mongoc_write_concern_is_default determines whether any
write concern options have been set, and
mongoc_read_concern_is_default checks if read concern options are set.
- mongoc_gridfs_find_one_with_opts optimized to use limit 1.

each interface attempted (e.g., if the driver first tries IPv6, then
IPv4).
- New error code MONGOC_ERROR_DUPLICATE_KEY.
- mongoc_collection_find no longer treats the "filter" key specially in
queries - querying for a document with a key named "filter" is the
same now as any other key.
- The server description parameter to the following functions is
"const":

MONGOC_ERROR_COLLECTION for other errors. mongoc_bulk_operation_execute
continues to use MONGOC_ERROR_COMMAND for all errors.
- If mongoc_client_pool_t fails to start its scanner thread in the
background, it logs and aborts instead of silently continuing, then
failing to connect.
- The driver now updates its view of the whole topology with information
from each new connection handshake.

- --enable-experimental has been removed. All previously experimental
features are now always on.
- The configure option "--enable-hardening" had had no effect. It is
removed in favor of system-wide compiler configuration.
mongo-c-driver 1.4.2
- Fixes bugs in "minPoolSize" logic, see CDRIVER-1558 for details.
mongo-c-driver 1.4.1
- mongoc_client_get_server_descriptions could return a list
including NULLs
- Tailable cursors on MongoDB 3.2 only worked with
MONGOC_QUERY_AWAIT_DATA
- Spurious warnings with MONGOC_DISABLE_SHM
- The driver can now use the native TLS and crypto functions
included in Mac OS X and Windows.
- The driver implements the MongoDB Command Monitoring Spec.
- New functions mongoc_client_set_error_api and
mongoc_client_pool_set_error_api
allow applications to distinguish client and server errors.
- Unacknowledged writes (writes whose mongoc_write_concern_t "w"
value is zero) now reply with an empty document instead of one
with nInserted: 0, nUpdated: 0, and so on.
- Public API For Higher-Level Drivers
- New connection string option "localThresholdMS".
- zSeries, POWER8, and ARM 64-bit platform support.
- Performance enhancements, reduce allocation and copying in
command code.
- All man page names now begin with "mongoc_" to avoid install
conflicts.
- New function mongoc_gridfs_file_set_id.
1.3.5
This release fixes a crash in mongoc_cleanup when an allocator
had been set with bson_mem_set_vtable, and introduces
a configure option MONGOC_NO_AUTOMATIC_GLOBALS which prevents
code built with GCC from automatically calling mongoc_init and
mongoc_cleanup when your code does not.
1.3.4
This release fixes a security vulnerability: when a mongoc_client_t
uses SSL and is disconnected, it failed to re-verify the server
certificate after reconnecting. This flaw affects
single clients, not pooled ones.
1.3.3
- Fix a bug where a slightly-oversized bulk write operation was not split
into batches; instead, it was sent whole to the server, which rejected it.
1.3.2
- A socket is properly discarded after a network error from a command.
- mongoc_database_get_collection now copies the database's read preferences,
read concern, and write concern, instead of copying the client's.
- mongoc_cursor_t's private struct now allows a negative limit.
1.3.1
- mongoc_client_get_gridfs now copies the client's read preferences, read
concern, and write concern to the newly created mongoc_gridfs_t. Before
this fix, GridFS operations were always executed with the default config:
data was read from the primary, with the read concern level "local", and
written with write concern "acknowledged". Now, if you have configured
any of these options on the mongoc_client_t, they are respected by
the mongoc_gridfs_t.
- CMakeLists.txt now includes and installs the pkg-config files.
pkgsrc changes:
- Release tarballs cannot build man pages any more, use pre-built
ones instead.
Changes since 1.2.1:
- If the driver is compiled without SSL support but a URI with "ssl=true"
is passed to mongoc_client_new, mongoc_client_new_from_uri, or
mongoc_client_pool_new, the function logs an error and returns NULL.
Before, the driver would attempt a non-SSL connection.
- mongoc_collection_find_and_modify will now apply the mongoc_collection_t's
write_concern_t when talking to MongoDB 3.2.
- Support for MongoDB 3.2's "readConcern" feature for queries, counts,
and aggregations. The option "readConcernLevel" is now accepted in
the MongoDB URI.
- Support for MongoDB 3.2's "bypassDocumentValidation" option for writes.
- New struct mongoc_bulk_write_flags_t and related functions.
- New struct mongoc_find_and_modify_opts_t and related functions.
- New functions to copy database and collection handles.
- Support for MongoDB 3.2 wire protocol: use commands in place of OP_QUERY,
OP_GETMORE, and OP_KILLCURSORS messages.
- To explain a query plan with MongoDB 3.2, you must now call the "explain"
command, instead of including the "$explain" key in
a mongoc_collection_find query. See the mongoc_collection_find
documentation page for details.
- Configurable wait time on tailable cursors with MongoDB 3.2.
- Use electionId to detect a stale replica set primary during
a network split.
- Disconnect from replica set members whose "me" field does not match
the connection address.
- The client side matching feature, mongoc_matcher_t and related functions,
are deprecated and scheduled for removal in version 2.0.
- New CMake options ENABLE_SSL, ENABLE_SASL, ENABLE_TESTS, and
ENABLE_EXAMPLES.
- Use constant-time comparison when verifying credentials.
- Combine environment's CFLAGS with configure options when building.
- Improved man page output and "whatis" entries.
Problems found with existing distfiles:
distfiles/D6.data.ros.gz
distfiles/cstore0.2.tar.gz
distfiles/data4.tar.gz
distfiles/sphinx-2.2.7-release.tar.gz
No changes made to the cstore or mariadb55-client distinfo files.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.

gains. Same for remove operations. (Inserts were always coalesced.)
- Large numbers of insert operations are now properly batched according
to number of documents and total data size.
- GSSAPI / Kerberos auth now works.
- The driver no longer tries three times in vain to reconnect to a primary,

A new libmongoc-priv.so library is installed that does not have symbols
hidden. You can access private headers via the -private.h variants. This
means you will need to recompile your project every time the library is
changed (if you use those private headers, as they are subject to change).
For other minor changes, see commits made since 0.98.0:
https://github.com/mongodb/mongo-c-driver/compare/0.98.0...1.0.0
Changes in 0.98.0:
- This release is primarily a bugfix release and stabilization effort as we
approach 1.0 of the MongoDB C driver.
- This release requires 0.98.0 of Libbson for improvements to the memory
management system. You can now setup custom memory allocators at the
start of the process.
Changes in 0.96.4:
- build/mci.sh script for automatically building Debian packages, RPMs,
and Solaris packaging based on the host operating system.
- Various libbson improvements, now depending on 0.8.4.
- Alignment fixes for Solaris Studio C compiler via libbson.
- Addition of mongoc_gridfs_remove_by_filename() for removing a file from
gridfs by filename.
- client command functions can now take a fully qualified namespace.
- collections can now support names that indicate a command namespace.
- Commands will no longer fail if they do not contain an "ok" field.
- OP_QUERY will now set the slaveOk bit in the wire protocol if
readPreferences are set to non-PRIMARY.
- Various documentation and build fixes.
Changes in 0.96.2
-----------------
* Ensure batchSize is used in cursor GETMORE operations with `aggregate`.
* Ensure enough buffer space is allocated for incoming RPC when buffering
from a stream.
* Require libbson 0.8.2 for more robust `bson_next_power_of_two()` when
using `size_t` and BCON compilation fix with C++.
* Handle cursor id's that are not 64-bit values in response from
`aggregate` command.
* Handle upsert on MongoDB < 2.6 when _id does not contain an `ObjectId`.
* Use 100 for default batchSize in `aggregate` command.
Changes in 0.96.0
-----------------
This release includes much new documentation, which can be found at
http://docs.mongodb.org/ecosystem/drivers/c/.
Additionally, this release improves support for various exotic systems.
Solaris 10 is supported much better on SPARC and x86_64 based systems.
Some workarounds for mixed-mode sharded-clusters have been added to improve
resiliency when rolling upgrades are performed.
Build improvements have been added to help us detect SASL and SSL
implementations on platforms that do not support pkg-config. This should
simplify building for some of you.
We've added some more logging to SASL authentication to help debug
authentication failures.
A bug causing an abort() when SSL is used and a server is down has been fixed.
We've renamed various _delete() functions to _remove() to provide consistency
with other MongoDB drivers.
You can now specify SSL options for client pools.
-D_REENTRANT is always defined now on Solaris to help with errno detection.
This may not have been done before if using a non-GCC platform with pthreads.
A bug was fixed where timeouts could have been 1000x longer than expected
due to failure to convert from microseconds to milliseconds.
A bug was fixed with authentication in sharded cluster and replica set
scenarios.
