Adds ActivitySource-based StartActivity/RecordException helper used across all packages for Activity-based tracing (OpenTelemetry-compatible), plus null guards in ExpressionInspector and a dedicated Abstractions.Tests project.
…lder, instrument with diagnostics - GenericRepository<T,TKey> wraps ValiFlowEvaluator<T> (GetById/GetAll/GetPaged/Add/Update/Delete/SaveChanges) - Extract query-construction logic from ValiFlowEvaluator into QuerySpecificationBuilder (SRP) - Wrap read/write evaluator methods with ValiFlowDiagnostics Activity tracing, tags derived from specification shape - Fix UpsertRangeAsync duplicate-key bug (dictionary accumulator instead of list)
…ak, add diagnostics tags - Split ValiFlowEvaluator<T,TProperty> (904 lines) into Bridge/Read/Write/Grouped partial files - Fix Update(entity, externalList) leaking into internal store on a later bare SaveChanges() - Add optional tag parameter across read/write/grouped methods, wired to ValiFlowDiagnostics Activity
…s, add SetAllFrom and diagnostics - Add SqlIdentifierGuard (regex whitelist) to validate table/schema/type names before interpolation - Fix OrIgnore/OrReplace dialect guard bug, Set()-after-SelectFrom() silent data loss, Where() double-call overwrite - Add AllowDeleteUnmatched() guard before WhenNotMatchedBySourceDelete in SqlMergeBuilder - Add SetAllFrom(entity, exclude...) reflection-based bulk column mapper to Insert/Update builders - Wrap all 6 builders' Build() with ValiFlowDiagnostics Activity tracing using the existing .Tag(...) value
…iteral null x.Field == nullVariable (closure) threw ArgumentNullException unlike x.Field == null (literal) — TranslateComparison now builds a NullNode when the evaluated value is null, same as the literal path.
…h IN values, add diagnostics - Escape RediSearch query-syntax special characters in LIKE patterns before adding wildcards, fixing a query injection vulnerability (e.g. pattern containing ')' or '|') - Fix customConverter not applied in Redis VisitComparison/numeric VisitIn - Fix swallowed inner exception in Elasticsearch ToDouble - Add MaxInValues caps (Mongo 10_000, Elasticsearch 65_536 matching index.max_terms_count) - Wrap Translate(...) with ValiFlowDiagnostics Activity tracing (tag + entityType)
Translate(...) now opens a ValiFlowDiagnostics Activity (tag + entityType), consistent with the other NoSql providers.
- Vali-Flow.NoSql.Couchbase: N1QL (SQL++) WHERE-fragment translator, no SDK dependency - Vali-Flow.NoSql.CosmosDb: Cosmos SQL API WHERE-fragment translator, no SDK dependency - Vali-Flow.NoSql.Firestore: native Google.Cloud.Firestore.Filter translator (LikeNode and generic NotNode throw NotSupportedException — SDK has no pattern-matching query and no NOT over an arbitrary sub-filter) - Add bilingual docs (en/es) and wire all 3 into the solution
Adds EfCoreBenchmarks + BenchmarkDbContext, referencing Vali-Flow.csproj directly (ProjectReference, consistent with this project's existing pattern for InMemory/Sql).
Add the 3 new NoSql providers (Couchbase, CosmosDb, Firestore) to the package table and architecture diagram; update benchmarks docs for the EF Core benchmark. Extend .gitignore for internal-tooling files that must never be tracked.
…itionUpsertRange CurrentValues.SetValues(entity) copies every scalar property by name, including the primary key. When upserting by a business key (e.g. a Sku), the caller's incoming entity normally carries a freshly-generated Id unrelated to the existing row's PK, and EF throws 'is part of a key and so cannot be modified' instead of updating in place. Align the incoming entity's PK value(s) with the tracked entity's PK before SetValues, via FindPrimaryKey() + reflection (supports composite keys). Found while stress-testing the EF Core evaluator under realistic upsert payloads (UpsertRangeAsync with duplicate business keys under concurrent load). Also bump Vali-Flow.Abstractions pin from 1.0.0 to 1.1.0 to match the version every other package in the solution already pins.
Add 96 tests covering previously-untested paths: the explicit IQueryReader<T>/ IQueryAggregator<T> interface members on ValiFlowEvaluator, BasicSpecification/ QuerySpecification fluent setters and QuerySpecificationBuilder guard clauses, long/float/double overloads of *ByGroupAsync, GenericRepository.SaveChangesAsync, ServiceCollectionExtensions.AddValiFlowEvaluator, remaining catch/RecordException branches, pagination guards, the relational DeleteByConditionCoreAsync path, and the rollback-itself-fails branch of RollbackTransactionAsync. Remaining uncovered lines are dead/unreachable defensive code, documented inline rather than forced with artificial tests.
…r entity type + key columns
EFCore.BulkExtensions' PostgreSQL adapter implements the upsert via a temporary
unique index with a deterministic name (tempUniqueIndex_{schema}_{table}_{column}),
created then dropped around the merge. Concurrent calls against the same
table/key columns race on that shared temp index, surfacing as
'42704: index "tempUniqueIndex_..." does not exist' — reproduced with as few
as 8 parallel single-row requests in the same process during stress testing.
Add an in-process SemaphoreSlim gate keyed by (entity type, UpdateByProperties)
to serialize same-key calls. Does NOT cover cross-process concurrency (multiple
API instances) — that collision still exists at the database level and would
need a Postgres advisory lock or equivalent; documented as a known limitation.
…cross SQL Server, PostgreSQL, MySQL, and SQLite Adds BulkUpsertRetryPolicy: a provider-agnostic retry (exponential backoff + jitter, no hard dependency on any ADO.NET provider) for the cross-process concurrency window the in-process semaphore gate (added for the stress-test finding on BulkInsertOrUpdateAsync) doesn't cover. Detects transiency via message-chain markers for the documented concurrency failure mode of each of the four most-used relational engines this ecosystem targets: - PostgreSQL/MySQL: EFCore.BulkExtensions' temporary unique index/constraint race when matching by BulkConfig.UpdateByProperties (the original finding). - SQL Server: deadlock victim on the bulk merge (documented upstream, EFCore.BulkExtensions issue #46). - SQLite: SQLITE_BUSY 'database is locked' under a concurrent writer. Oracle is deliberately not covered -- supported by EFCore.BulkExtensions but a materially less common deployment target, and its failure wording for this race hasn't been characterized. Wires the same gate+retry path into BulkUpdateAsync (previously only BulkInsertOrUpdateAsync was covered) since both share the identical BulkConfig.UpdateByProperties exposure. Adds InternalsVisibleTo so the retry policy can be unit-tested in isolation (21 new tests, no EF Core/database involved -- the race itself can't be reproduced deterministically against the InMemory/SQLite test providers) plus a BulkUpdateAsync concurrency regression test mirroring the existing BulkInsertOrUpdateAsync one.
…7 attempts Validated the retry against the real cross-process scenario it targets: 2 API instances, 50 req/s combined, 15 shared business keys via BulkInsertOrUpdateAsync. The mechanism worked (113 retries triggered, 0 duplicate rows), but the original 4-attempt / 400ms-max-delay budget (~450ms total) left ~2% of requests (8/405) exhausting all retries and propagating a 500 (40P01 deadlock detected, 42704 index does not exist) under sustained contention. Raised to 7 attempts / 900ms max delay to give the losing side of the race more chances to land after the winner releases the temp index/lock. Also confirmed Postgres' actual deadlock error code (40P01, not the originally assumed 42704) still matches the existing generic "deadlock" substring marker without any change needed there.
Second measured iteration: 7 attempts cut the propagated-error rate from ~2% (8/405) to 0.12% (1/855) under the same artificially-high-contention benchmark (2 API instances, 50 req/s combined, 15 shared keys) -- real improvement, not zero. Raised to 12 attempts (~5.4s worst-case backoff budget) to push residual failure rate further down under this deliberately narrow pool. Documented in the constant's XML remarks that no finite retry budget can offer a 0% proof for a queueing race -- only diminishing residual probability at the cost of added worst-case latency.
…ByProperties key set A stress run sweeping the shared business-key pool from 15 up to 1,000 and 10,000 distinct SKUs found the retry activation rate unchanged across every pool size (consistently ~20-25 activations per instance), ruling out key collision as the cause. The real contention is PostgreSQL's CREATE INDEX CONCURRENTLY (part of the merge EFCore.BulkExtensions runs for a non-PK match), which serializes against any other transaction on the same table regardless of which rows/columns it touches. The in-process gate was keyed by (type, UpdateByProperties columns), which would let two same-process calls with different UpdateByProperties on the same table run concurrently and still race -- re-keyed to type (table) alone, matching the real contention boundary. GetBulkUpsertGate no longer needs the BulkConfig parameter.
…/InMemory test assemblies
A full-solution test run surfaced an intermittent failure in Vali-Flow.Sql.Tests
('Sequence contains no matching element') in the diagnostics tests added by an
earlier commit. Root cause: each test parents its captured System.Diagnostics.
Activity under a private root and filters by ParentId to survive cross-test
pollution on the shared process-wide ValiFlowDiagnostics.Source listener -- but
under xUnit's default test-class-level parallelism this is not fully
deterministic; it just has lower collision probability with fewer competing
Activity-asserting test classes, which is why it hadn't surfaced yet in
Vali-Flow.Tests/Vali-Flow.InMemory.Tests (same pattern, fewer classes) and did
in Vali-Flow.Sql.Tests (6 builder test classes all asserting on Activities).
Fixes, in order:
1. Rewrote the 6 duplicated per-file ActivityListener setups in Sql.Tests
(SqlDeleteBuilderTests, SqlInsertBuilderTests, SqlMergeBuilderTests,
SqlTruncateBuilderTests, SqlUpdateBuilderTests, SqlQueryBuilderTests) to use
the same AttachScopedListener/GetOwn helper pattern already used elsewhere,
removing a dead/unused AttachListener() helper and a redundant double-listener
in SqlQueryBuilderTests along the way.
2. Added [assembly: CollectionBehavior(DisableTestParallelization = true)] to
Vali-Flow.Sql.Tests, Vali-Flow.Tests, and Vali-Flow.InMemory.Tests -- removes
the race at its source instead of chasing per-test correlation tokens.
Verified clean across 8 consecutive Sql.Tests runs and 5 consecutive
full-solution runs. Cost: Sql.Tests went from ~250ms to ~800ms, negligible.
… strings ResolveValue converted decimal to a string (m.ToString(InvariantCulture)) for every operator (=, <>, <, <=, >, >=). N1QL has no decimal type and does NOT coerce between string and number in comparisons (its collation order puts number < string unconditionally) -- a string-bound parameter silently matched zero rows against a numeric field, for every operator, 100% of the time. Found running the translator's N1QL output against a real Couchbase Server (Caso A stress validation): EqualNode(decimal) and ComparisonNode(decimal) failed in all 3 tested scales (1K/20K/100K docs) while the equivalent int field worked correctly. Mongo/Elasticsearch/DynamoDB translators already preserve the native numeric type for decimal; Couchbase was the only one converting it to string.
…ackageReference 1.2.0
…eference 1.1.1 in the 7 NoSQL providers
These 3 providers were scaffolded without the package icon file this session, causing dotnet pack to fail with NU5046 (PackageIcon set in csproj but file absent). Copied from Vali-Flow.NoSql, which ships the same icon.
…GenericRepository, diagnostics, security fixes) - Root CHANGELOG.md [Unreleased]: documents everything shipped since the last entry (1.3.3, April) that was never logged — 3 new NoSQL translator packages (Couchbase, CosmosDb, Firestore), GenericRepository<T,TKey>, ValiFlowDiagnostics observability helper, the SQL identifier injection fix, the RediSearch query injection fix, Mongo/Elasticsearch IN-value caps, the bulk upsert retry policy (and its budget tuning 4->7->12), and several smaller bug fixes across Sql/NoSql/InMemory/EF Core. - Created CHANGELOG.md for the 3 new packages (Couchbase/CosmosDb/Firestore had none), following the existing per-package format. - Fixed Vali-Flow.NoSql.MongoDB/CHANGELOG.md: described a stale API (ToMongoFilter<T>() -> FilterDefinition<T>) that doesn't match the real current one (ToMongo<T>() -> BsonDocument, verified against docs/en/vali-flow-nosql-mongodb.md and the actual extension method source) — found independently by 3 separate doc-porting passes while researching the new providers.
All packages build for net8.0/net9.0 only, but run unmodified on .NET 10 via forward compatibility. Documented that explicitly everywhere a .NET version requirement is stated (README, architecture overview, getting started guide, EF Core evaluator requirements) — en + es.

Reemplazado por un flujo de 3 PRs secuenciales (una por ola de dependencia), ver #4 para wave 1. Motivo: el CI de este PR fallaba porque Vali-Flow.Abstractions 1.2.0 / Vali-Flow.NoSql 1.1.1 no existen todavía en NuGet.org — al bundlear las 3 olas en un solo PR, el restore no podía resolver referencias a versiones aún no publicadas. Secuencia nueva: wave-1 (solo bump de Abstractions, sin repoint) → merge + publish real → wave-2 (repoint a 1.2.0 + bump Vali-Flow/InMemory/Sql/NoSql) → merge + publish real → wave-3 (repoint a NoSql 1.1.1 + bump de los 7 proveedores). |
