Tarantool 2.10.4

Released on 2022-11-11.

Release: v. 2.10.4.
Tag: 2.10.4.

Overview

2.10.4 is the fifth stable version of the 2.10 release series. It introduces 5 improvements and resolves 28 bugs since 2.10.3.

The “stable” label means that we have all planned features implemented and we see no high-impact issues. However, if you encounter an issue, feel free to report it on GitHub.

Compatibility

Tarantool 2.x is backward compatible with Tarantool 1.10.x in the binary data layout, client-server protocol, and replication protocol.

Please upgrade using the box.schema.upgrade() procedure to unlock all the new features of the 2.x series.

Note

Now the empty string, n, nu, s, and st (that is, leading parts of num and str) are not accepted as valid field types (gh-5940). This instruction will help you upgrade to Tarantool 2.10.4 and newer if you’ve previously used these values in field types.

Functionality added or changed

Core

The JSON log format can now be used with the syslog logger (gh-7860).

SQL

New rules are applied to determine the type of CASE operation (gh-6990).
Now NULLIF() call results have the same type as its first argument (gh-6989).

Build

Diagnostics now provide relative file paths instead of absolute ones (gh-7808).
Now the compiler info displayed in tarantool.build.compiler and tarantool --version shows the ID and the version of the compiler that was used to build Tarantool. The output has the format ${CMAKE_C_COMPILER_ID}-${CMAKE_C_COMPILER_VERSION}, for example, Clang-14.0.0.14000029 (gh-7888).

Bugs fixed

Core

Fixed creation of spaces with a constraint and a foreign key on the same field (gh-7645).
Now the same error is returned when a password or a username provided during authorization is incorrect. This prevents user enumeration (ghs-16).
Added boundary checking for getenv() return values. Also, for security reasons, Tarantool code now copies these values instead of using them directly (gh-7797).
os.getenv() now always returns values of sane size (gh-7797).
Fixed the BEGIN, COMMIT, and ROLLBACK counters in the box.stat() output. Now they show the number of started, committed, and rolled back transactions (gh-7583).
Fixed a crash that could occur during log rotation and application exit (gh-4450).
Fixed a possible buffer overflow in mp_decode_decimal() and decimal_unpack() when an input string was too long (ghs-17).
Fixed a bug in the MsgPack library that could lead to a failure to detect invalid MsgPack input and, as a result, an out-of-bounds read (ghs-18).
If an error occurs during a snapshot recovery, its log now contains information about the row that caused the error (gh-7917).

Memtx

Fixed possible loss of committed tuples in secondary indexes with MVCC transaction manager (gh-7712).
Fixed an assertion being triggered on space:drop (gh-7757).
Fixed possible violation of the secondary index uniqueness with the transaction manager enabled (gh-7761).

LuaJIT

Backported patches from vanilla LuaJIT trunk (gh-7230). In the scope of this activity, the following issues have been resolved:
- Fix overflow check in unpack() optimized by a compiler.
- Fix recording of tonumber() with cdata argument for failed conversions (gh-7655).
- Fix concatenation operation on cdata. It always raises an error now.
Fixed the Lua stack dump command (lj-stack) to support Python 2: unpacking arguments within the list initialization is not supported in it (gh-7458).

Lua

Fixed a crash in msgpack.decode in case the input string contains an invalid MsgPack header 0xc1 (gh-7818).

SQL

Fixed an assertion when INDEXED BY was used with an index that was at least third in a space (gh-5976).
Fixed a crash that could occur when selecting tuples with more fields than specified in the space format (gh-5310, gh-4666).
Fixed an assertion in JOIN when using an unsupported index (gh-5678).
Creating indexes on newly added fields no longer leads to assertions in SELECT queries (gh-5183).
Re-running a prepared statement that generates new auto-increment IDs no longer causes an error (gh-6422).
An error is now thrown if too many indexes were created in SQL (gh-5526).

Box

Revoked execute access rights to the LUA function from the public role (ghs-14).
Now the empty string, n, nu, s, and st (that is, leading parts of num and str) are not accepted as valid field types (gh-5940). This instruction will help you upgrade to Tarantool 2.10.4 and newer if you’ve previously used these values in field types.
Fixed a bug when type = box.NULL in key_def.new() resulted in type = 'unsigned' (gh-5222).
The _vfunc system space now has the same format as _func (gh-7822).
Fixed a crash on recovery from snapshots that don’t include system spaces (gh-7800).
Fixed a bug that occurred when a foreign key was created together with fields that participate in that foreign key (gh-7652).

Datetime

Fixed interval arithmetic for boundaries crossing DST (gh-7700).

Results of datetime arithmetic operations could get a different timezone if the DST boundary has been crossed during the operation:
```
tarantool> datetime.new{year=2008, month=1, day=1,
                        tz='Europe/Moscow'} +
           datetime.interval.new{month=6}
---
- 2008-07-01T01:00:00 Europe/Moscow
...
```
Now we resolve tzoffset at the end of operation if tzindex is not 0.

Fixed subtractions for datetimes with different timezones (gh-7698).

Previously, the timezone difference (tzoffset) was ignored in datetime subtraction operations:

tarantool> datetime.new{tz='MSK'} - datetime.new{tz='UTC'}
---
- +0 seconds
...
tarantool> datetime.new{tz='MSK'}.timestamp -
           datetime.new{tz='UTC'}.timestamp
---
- -10800
...

Now this difference is accumulated in the minute component of the resulting interval:

tarantool> datetime.new{tz='MSK'} - datetime.new{tz='UTC'}
---
- -180 minutes
...
