      @TarantoolBot document
      Title: new box.cfg parameter memtx_sort_threads
      
      The parameter sets the number of threads used to sort keys of secondary
      indexes on loading memtx database. The parameter cannot be changed
      dynamically (as it does not make sense).
      
      Maximum value is 256, minimum is 1. Default is to use all available cores.
      
      Usage example:
      ```
      box.cfg{memtx_sort_threads=4}
      ```

      core: introduce sample sort algorithm · cb2a2df2
      Nikolay Shirokovskiy authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      The algorithm runs sort in multiple threads and does not use OpenMP. It
      has better threads utilization right from the beginning but probably
      a worse constant than parallel qsort. See details in code comments.
      
      Besides sort is not performed in calling thread but instead in spawned
      worker threads. Calling thread yields waiting for worker threads to
      finish. Exception is small data size, in this case sorting is executed
      in calling thread saving time on spawning a thread. This should speed up
      test execution. This is existing behaviour of qsort_arg but data size
      threshold is reduced from 128000 to 1024.

      feat: extend C box API with a new auth method · 1f949ad8
      Denis Smirnov authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      1. Current commit introduces 'box_auth_data_prepare()' to prepare
         a data string for any supported authentication methods.
      2. The user name argument is refactored in the auth methods: the
         null-terminated string is replaced with an address range approach.
         Now Rust users don't need to re-allocate username with CString.
      3. Password length type was set to uint32_t (previously it was size_t,
         int, uint32_t for different functions). Tarantool uses murmur3a,
         so all the hashed strings should be up to 32 bit long.

      box: fully temporary spaces · 373342aa
      Georgy Moshkin authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Introduce fully temporary spaces: same as data-temporary space but with
      temporary metadata. Basically temporary spaces now do not exist on
      restart and do not exist on replicas. They can also be created, altered
      and deleted when box.cfg.read_only = true.
      
      To avoid conflicts with spaces created on replicas, the temporary
      space ids by default start in a special range starting at
      BOX_SPACE_ID_TEMPORARY_MIN.
      
      Temporary spaces currently do not support several features e.g.
      foreign key references (to and from), functional indexes, sql sequences,
      sql triggers, etc. This may change in the future.
      
      Implementing temporary spaces requires temporary tuples to be
      inserted into system spaces: tuples which are neither replicated or
      persisted. This mostly done in on_replace_dd_* triggers by dropping the
      txn->stmt->row.
      
      Closes #8323

      Georgy Moshkin authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Everywhere where we refer to temporary spaces we now say data-temporary.
      This is because temporary spaces were never truly temporary because
      their definitions would still be persisted and replicated and they
      couldn't be created on read-only replicas. In a following commit we will
      introduce a new fully temporary type of spaces, which will be just
      called 'temporary', so this commit signifies this terminology change.

      Introduces a new field `type` to the space definition. Currently it can
      only be "normal" or "data-temporary". It is backwards compatible with
      temporary=true.
      
      @TarantoolBot document
      Title: Introduce space field type
      
      A new space definition field "type" can now be used to specify the type
      of the space. Usage: box.schema.create_space("s", { type = "normal" }).
      Currently only 2 types are supported: "normal" & "data-temporary", which
      is equivalent to { temporary = true }. Old-style { temporary = true } is
      still supported, but only one option either 'temporary' or 'type' may be
      specified at the same time.
      
      Space type "temporary" will be introduced in a later commit.
      In the future options "local", "synchronous", etc. may also be
      supported.

      sql: refactor update_view_references a bit · d6d918bb
      Aleksandr Lyapunov authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      The function update_view_references is called when an SQL view
      is created or dropped. The goal of this function is to modify
      (increment or decrement) view_ref_count member of spaces that
      the view references.
      
      There were a several issues that deserves to be refactored:
      * By design in case of error it left the job partially done, so
        some space references were modified while some other - not.
        Although there was no bug since special steps were made in case
        of error, this pattern is inconvenient and should be avoided.
      * In case of error the failing space name was returned via special
        argument which is not flexible and even requires allocation.
      * Another argument - suppress_error - has actually never
        suppressed any error because the only case when an error could
        occur is creation of a view, which used suppress_error = false.
      * Fail of that function was not actually covered with tests.
      
      So this commit:
      * Makes the function to do all or nothing.
      * Forces the function to set diag by itself in case of error.
      * Removes suppress_error argument while adding several asserts.\
      * Adds a small test that fulfills coverage.

      box: support default field values in the space format · 9ec54fa3
      Ilya Verbin authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Now a field can be assigned a default value in the space format. When a new
      tuple is inserted into a space, and some of the fields contain null values,
      those fields will be filled with their respective default values.
      
      Closes #8157

      Title: Document default field values
      Product: Tarantool
      Since: 3.0
      Root document: https://www.tarantool.io/en/doc/latest/reference/reference_lua/box_space/format/
      
      The format clause contains, for each field, a definition within braces:
      `{name='...',type='...'[,is_nullable=...][,default=...]}`, where:
      
      * the optional `default` value contains a default value for the field.
        Its type must be compatible with the field type. If default value is set,
        it is applied regardless of whether `is_nullable` is true or false.
      
      Example:
      
      ```lua
      tarantool> box.space.tester:format{
               > {name = 'id', type = 'unsigned'},
               > {name = 'name', type = 'string', default = 'Noname'},
               > {name = 'pass', type = 'string'},
               > {name = 'shell', type = 'string', default = '/bin/sh'}}
      ---
      ...
      
      tarantool> box.space.tester:insert{1000, nil, 'qwerty'}

      fix: Establish LDAP connections implicitly · c06d234b
      Dmitry Ivanov authored
      Unfortunately, Centos 7 provides only openssl 1.0.2 (at lest if we
      disregard epel), so we can't build the bundled libldap & libsasl2.
      "Okay", one might think, "we can link against the distro's libs".
      Well, turns out libldap 2.4, which is what we have to deal with in
      that case, doesn't have ldap_connect!
      
      Luckily, we don't have to connect explicitly. According to man pages:
      
      ```
      ldap_init() acts just like ldap_open(), but does not open a connection
      to the LDAP server.  The actual connection open will occur when the
      first operation is attempted.
      
      ldap_initialize()  acts  like ldap_init()...
      ```
      
      This is still true for libldap up to and including version 2.6.

      Dmitry Ivanov authored
      This authentication method doesn't store any secrets; instead,
      we delegate the whole auth to a pre-configured LDAP server. In

      ```lua
      -- Set the default auth method to LDAP and create a new user.
      -- NOTE that we still have to provide a dummy password; otherwise
      -- box.schema.user.create will setup an empty auth data.

      feat: implement md5 authentication · 30038100
      Maksim Kaitmazian authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      It prevents password sniffing and avoids storing passwords on the
      server in plain text but provides no protection if an attacker
      manages to steal the password hash from the server.
      
      Usage example:
      ```lua
      -- Enable the md5 authentication method for all new users.
      box.cfg({auth_type = 'md5'})
      
      -- Reset existing user passwords to use the md5 authentication method.
      box.schema.user.passwd('alice', 'topsecret')
      
      -- Authenticate using the md5 authentication method via net.box.
      conn = require('net.box').connect(uri, {
          user = 'alice',
          password = 'topsecret',
          -- Specifying the authentication method isn't strictly necessary:
          -- by default the client will use the method set in the remote
      	-- server config (box.cfg.auth_type)
          auth_type = 'md5',
      })

      feat: add user name argument to `auth_method` api · e749fbf1
      Maksim Kaitmazian authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      User name is usually used as a salt for user password in order to
      avoid password repeating.
      For instance, postgres md5 authentication stores passwords as
      md5("password", "user"), so that the same passwords are represented by
      different hashes.

      Title: Document updated `box.schema.user.password` declaration.
      
      Since auth methods can use user name for hashing, user name is
      added to argument list of `box.schema.user.password`.

      feat: expose tuple hash calculation method · e1ce65e8
      Denis Smirnov authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Picodata supports cluster-wide SQL and needs some predictable
      method to calculate tuple hashes for the bucket ids. Method
      should be available for Lua, C and Rust users. It was decided
      to expose a murmur3 hash calculation method of the key_def module.

      cbus: introduce lcpipe - light cpipe · d653d088
      godzie44 authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Introduced a new type of cbus pipe - lcpipe. The current pipe in the
      cbus - cpipe, has a number of limitations, first of all - the cpipe
      cannot be used from the 3rd party threads, cpipe only works as a channel
      between two cords. That why lcpipe is needed. Its main responsibility -
      create channel between any thread and tarantool cord.
      
      Internally lcpipe is a cpipe, but:
      - on flush triggers removed, cause triggers use thread-local mem-pool,
      this is not possible on a third party thread
      - producer event loop removed, cause there is no libev event loop in
      third party thread
      
      Also, lcpipe interface is exported to the outside world.

      feat(json): add option to encode decimals as string · a85eebb6
      Дмитрий Кольцов authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Due to inconsistency of Tarantool type casting while using strict
      data types as "double" or "unsigned" it is needed
      to use "number" data type in a whole bunch of cases.
      However "number" may contain "decimal" that will be serialized into
      string by JSON builtin module.
      
      This commit adds "encode_decimal_as_number" parameter to json.cfg{}.
      That forces to encode `decimal` as JSON number to force type
      consistency in JSON output.
      Use with catious - most of JSON parsers assume that number is restricted
      to float64.

      sql: recompile expired prepared statements · de6e983a
      Denis Smirnov authored and Dmitry Ivanov's avatar Dmitry Ivanov committed
      Actually there is no reason to throw an error and make a user
      manually recreate prepared statement when it expires. A much more
      user friendly way is to recreate it under hood when statement's
      schema version differs from the box one.
