fix: Handle empty FieldsData in reduce/rerank for requery scenario (#44917) (#45137)
issue: #44909
pr: #44917

When requery optimization is enabled, search results contain IDs but
empty FieldsData. During reduce/rerank operations, if the first shard
has empty FieldsData while others have data, PrepareResultFieldData
initializes an empty array, causing AppendFieldData to panic when
accessing array indices.

Changes:
- Find first non-empty FieldsData as template in 3 functions:
reduceAdvanceGroupBy, reduceSearchResultDataWithGroupBy,
reduceSearchResultDataNoGroupBy
- Add length check before 2 AppendFieldData calls in reduce functions to
prevent panic
- Improve newRerankOutputs to find first non-empty fieldData using
len(FieldsData) check instead of GetSizeOfIDs
- Add length check in appendResult before AppendFieldData
- Add comprehensive unit tests for empty and partial empty FieldsData
scenarios in both reduce and rerank functions

This fix handles both pure requery (all empty) and mixed scenarios (some
empty, some with data) without breaking normal search flow. The key
improvement is checking FieldsData length directly rather than IDs, as
requery may have IDs but empty FieldsData.

enhance: [2.6] extract shard client logic into dedicated package (#45018) (#45031)
Cherry-pick from master
pr: #45018 #45030
Related to #44761

Refactor proxy shard client management by creating a new
internal/proxy/shardclient package. This improves code organization and
modularity by:

- Moving load balancing logic (LookAsideBalancer, RoundRobinBalancer) to
shardclient package
- Extracting shard client manager and related interfaces into separate
package
- Relocating shard leader management and client lifecycle code
- Adding package documentation (README.md, OWNERS)
- Updating proxy code to use the new shardclient package interfaces

This change makes the shard client functionality more maintainable and
better encapsulated, reducing coupling in the proxy layer.

Also consolidates the proxy package's mockery generation to use a
centralized `.mockery.yaml` configuration file, aligning with the
pattern used by other packages like querycoordv2.

Changes
- **Makefile**: Replace multiple individual mockery commands with a
single config-based invocation for `generate-mockery-proxy` target
- **internal/proxy/.mockery.yaml**: Add mockery configuration defining
all mock interfaces for proxy and proxy/shardclient packages
- **Mock files**: Regenerate mocks using the new configuration:
  - `mock_cache.go`: Clean up by removing unused interface methods
  (credential, shard cache, policy methods)
  - `shardclient/mock_lb_balancer.go`: Update type comments
  (nodeInfo → NodeInfo)
  - `shardclient/mock_lb_policy.go`: Update formatting
  - `shardclient/mock_shardclient_manager.go`: Fix parameter naming
  consistency (nodeInfo1 → nodeInfo)
- **task_search_test.go**: Remove obsolete mock expectations for
deprecated cache methods

Benefits
- Centralized mockery configuration for easier maintenance
- Consistent with other packages (querycoordv2, etc.)
- Cleaner mock interfaces by removing unused methods
- Better type consistency in generated mocks

enhance: [2.6] Refactor privilege management by extracting privilege cache into separate package (#44762) (#45002)
Cherry-pick from master
pr: #44762

Related to #44761

This commit refactors the privilege management system in the proxy
component by:

1. **Separation of Concerns**: Extracts privilege-related functionality
from MetaCache into a dedicated `internal/proxy/privilege` package,
improving code organization and maintainability.

2. **New Package Structure**: Creates `internal/proxy/privilege/` with:
   - `cache.go`: Core privilege cache implementation (PrivilegeCache)
   - `result_cache.go`: Privilege enforcement result caching
   - `model.go`: Casbin model and policy enforcement functions
   - `meta_cache_adapter.go`: Casbin adapter for MetaCache integration
   - Corresponding test files and mock implementations

3. **MetaCache Simplification**: Removes privilege and credential
management methods from MetaCache interface and implementation:
   - Removed: GetCredentialInfo, RemoveCredential, UpdateCredential
- Removed: GetPrivilegeInfo, GetUserRole, RefreshPolicyInfo,
InitPolicyInfo
   - Deleted: meta_cache_adapter.go, privilege_cache.go and their tests

4. **Updated References**: Updates all callsites to use the new
privilegeCache global:
- Authentication interceptor now uses privilegeCache for password
verification
- Credential cache operations (InvalidateCredentialCache,
UpdateCredentialCache, UpdateCredential) now use privilegeCache
- Policy refresh operations (RefreshPolicyInfoCache) now use
privilegeCache
- Privilege interceptor uses new privilege.GetEnforcer() and privilege
result cache

5. **Improved API**: Renames cache functions for clarity:
   - GetPrivilegeCache → GetResultCache
   - SetPrivilegeCache → SetResultCache
   - CleanPrivilegeCache → CleanResultCache

This refactoring makes the codebase more modular, separates privilege
management concerns from general metadata caching, and provides a
clearer API for privilege enforcement operations.

feat: Geospatial Data Type and GIS Function support for milvus (#44547)
issue: #43427

This pr's main goal is merge #37417 to milvus 2.5 without conflicts.

# Main Goals

1. Create and describe collections with geospatial type
2. Insert geospatial data into the insert binlog
3. Load segments containing geospatial data into memory
4. Enable query and search can display  geospatial data
5. Support using GIS funtions like ST_EQUALS in query
6. Support R-Tree index for geometry type

# Solution

1. **Add Type**: Modify the Milvus core by adding a Geospatial type in
both the C++ and Go code layers, defining the Geospatial data structure
and the corresponding interfaces.
2. **Dependency Libraries**: Introduce necessary geospatial data
processing libraries. In the C++ source code, use Conan package
management to include the GDAL library. In the Go source code, add the
go-geom library to the go.mod file.
3. **Protocol Interface**: Revise the Milvus protocol to provide
mechanisms for Geospatial message serialization and deserialization.
4. **Data Pipeline**: Facilitate interaction between the client and
proxy using the WKT format for geospatial data. The proxy will convert
all data into WKB format for downstream processing, providing column
data interfaces, segment encapsulation, segment loading, payload
writing, and cache block management.
5. **Query Operators**: Implement simple display and support for filter
queries. Initially, focus on filtering based on spatial relationships
for a single column of geospatial literal values, providing parsing and
execution for query expressions.Now only support brutal search
7. **Client Modification**: Enable the client to handle user input for
geospatial data and facilitate end-to-end testing.Check the modification
in pymilvus.

feat: timestamptz expression & index & timezone (#44080)
issue: https://github.com/milvus-io/milvus/issues/27467

>- [x] M1 Create collection with timestamptz field
>- [x] M2 Insert timestamptz field data
>- [x] M3 Retrieve timestamptz field data
>- [x] M4 Implement handoff
>- [x] M5 Implement compare operator
>- [x] M6 Implement extract operator
 >- [x] M8 Support database/collection level default timezone
>- [x] M7 Support STL-SORT index for datatype timestamptz

---

The third PR of issue: https://github.com/milvus-io/milvus/issues/27467,
which completes M5, M6, M7, M8 described above.

## M8 Default Timezone

We will be able to use alter_collection() and alter_database() in a
future Python SDK release to modify the default timezone at the
collection or database level.

For insert requests, the timezone will be resolved using the following
order of precedence: String Literal-> Collection Default -> Database
Default.
For retrieval requests, the timezone will be resolved in this order:
Query Parameters -> Collection Default -> Database Default.
In both cases, the final fallback timezone is UTC.


## M5: Comparison Operators

We can now use the following expression format to filter on the
timestamptz field:

- `timestamptz_field [+/- INTERVAL 'interval_string'] {comparison_op}
ISO 'iso_string' `

- The interval_string follows the ISO 8601 duration format, for example:
P1Y2M3DT1H2M3S.

- The iso_string follows the ISO 8601 timestamp format, for example:
2025-01-03T00:00:00+08:00.

- Example expressions: "tsz + INTERVAL 'P0D' != ISO
'2025-01-03T00:00:00+08:00'" or "tsz != ISO
'2025-01-03T00:00:00+08:00'".

## M6: Extract

We will be able to extract sepecific time filed by kwargs in a future
Python SDK release.
The key is `time_fields`, and value should be one or more of "year,
month, day, hour, minute, second, microsecond", seperated by comma or
space. Then the result of each record would be an array of int64.



## M7: Indexing Support

Expressions without interval arithmetic can be accelerated using an
STL-SORT index. However, expressions that include interval arithmetic
cannot be indexed. This is because the result of an interval calculation
depends on the specific timestamp value. For example, adding one month
to a date in February results in a different number of added days than
adding one month to a date in March.

--- 

After this PR, the input / output type of timestamptz would be iso
string. Timestampz would be stored as timestamptz data, which is int64_t
finally.

enhance: Add granular flush targets support for FlushAll operation (#44234)
issue: #44156
Enhance FlushAll functionality to support targeting specific collections
within databases instead of only database-level flushing.

Changes include:

- Add FlushAllTarget message in data_coord.proto for granular targeting
- Support collection-specific flush operations within databases
- Maintain backward compatibility with deprecated db_name field

This enhancement allows users to flush specific collections without
affecting other collections in the same database, providing more precise
control over data persistence operations.

enhance: Optimize partial update merge logic by unifying nullable format (#44197)
issue: #43980
This commit optimizes the partial update merge logic by standardizing
nullable field representation before merge operations to avoid corner
cases during the merge process.

Key changes:
- Unify nullable field data format to FULL FORMAT before merge execution
- Add extensive unit tests for bounds checking and edge cases

The optimization ensures:
- Consistent nullable field representation across SDK and internal
- Proper handling of null values during merge operations
- Prevention of index out-of-bounds errors in vector field updates
- Better error handling and validation for partial update scenarios

This resolves issues where different nullable field formats could cause
merge failures or data corruption during partial update operations.
