Suggested reviewers: Merge Risk: 🔵 Low · up to This change adds configurable client library attribution and optional tags to connection setup, affecting the name reported through CLIENT INFO. It is mergeable with owner awareness because validation remains duplicated across client, cluster, and mock constructor paths, creating a bounded risk of inconsistent input handling. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 778-796: Extend both testStandaloneClientInfoTagWhitespaceRejected
and testClusterClientInfoTagWhitespaceRejected to pass a line-break whitespace
value such as "\n" or "\r\n" to their respective constructors, and assert the
same whitespace-rejection exception message.
In `@tests/ValkeyGlideClusterFeaturesTest.php`:
- Around line 51-55: Update the cluster test connection configurations to derive
use_tls from getTLS() instead of forcing false, and supply the TLS test
configuration whenever TLS is enabled. Apply this consistently to both address
configurations used by the test while preserving plaintext behavior when
getTLS() is false.
In `@tests/ValkeyGlideFeaturesTest.php`:
- Around line 60-62: Update the CLIENT INFO assertions in
tests/ValkeyGlideFeaturesTest.php at lines 60-62, 76-78, and 92-94, plus
tests/ValkeyGlideClusterFeaturesTest.php at lines 57-63 and 78-84: extract the
complete lib-name field from the rawcommand("CLIENT", "INFO") response and
assert exact equality with the expected metadata instead of using
str_contains().
In `@valkey_glide.stub.php`:
- Around line 386-387: Update the client_info_tag documentation in
valkey_glide.stub.php lines 386-387 and valkey_glide_cluster.stub.php lines
260-261 to describe the appended value as <resolved-lib-name>(tag), covering
both the default and explicitly configured lib_name cases; make no other
changes.

Addresses upstream review feedback from @nderraugh on PR valkey-io#292, and closes the scope question QA had deferred as L-4. MONITOR is arguably the most operationally visible connection a client opens, and it could not be attributed: ValkeyGlideMonitor accepted neither option and always reported bare "GlidePHP". As the reviewer noted, Go's NewMonitorClient shares one serializer with ordinary clients (cfg.ToProtobuf -> resolveLibName), so both produce the same effective name. PHP already had that shape -- the monitor constructor routes through valkey_glide_build_client_config_base() and create_connection_request() like the standalone and cluster paths -- it simply never accepted the two parameters. This wires them through and validates them with the same shared predicate, so accept/reject behaviour cannot drift from the other three entry points. Verified server-side rather than by construction: opening a monitor and matching the cmd=monitor row in CLIENT LIST reports GlidePHP, GlidePHP(framework:1.2), custom-lib, and custom-lib(framework:1.2) across the four matrix cases, and a space-bearing tag or a parenthesis-bearing lib_name raises ValkeyGlideException. Covered by testMonitorReportsComposedLibName and testMonitorRejectsInvalidMetadata. Also completes the round-1 M-1 documentation fix with the reviewer's second point, which QA had not raised: the ^[!-~]+$ expression not only permitted '(' and ')' but its '+' also implied at least one character, contradicting empty-means-unset. All four stub docblock groups now state that an empty string or null is treated as UNSET (yielding the default, and adding no "(tag)" suffix) and that only non-empty values are charset-constrained. Verification: ValkeyGlideMonitorTest 14, ConnectionRequestTest 107, ValkeyGlideFeaturesTest 94, ValkeyGlideClusterFeaturesTest 85 -- all passing, both new monitor tests confirmed to execute. Full suite back to the two known pre-existing failures. Investigation note for anyone bisecting: an interim full-suite run showed a third failure in the BGSAVE family (testBgSaveCancel, and once testBgSaveWithReplyLiteral instead). It was NOT caused by these changes -- the new monitor tests run long after ValkeyGlideClusterTest in class order, and reverting the run-loop catch merely moved the failure to a sibling test. It was transient server state: rdb_changes_since_last_save had drifted unevenly across nodes after an earlier flushall, and these tests depend on whether a background save is in progress. Two consecutive full runs on settled servers are clean. Signed-off-by: Jonathan Neufeld <jonathan.neufeld@improving.com>

…dings validate_effective_lib_name() lazily compiles a process-lifetime LazyLock<Regex> (LIB_NAME_PATTERN) the first time client_info_tag or lib_name is validated. Its regex-automata lazy DFA cache grows an internal hashbrown table on first use and is intentionally never freed before process exit, matching the existing DashMap/OnceLock suppression patterns already in this file. Valgrind's --error-exitcode=1 gate failed PR valkey-io#292's CI on two 'possibly lost' records (332 bytes total, 0 definitely/indirectly lost) at exactly this call site: cache init during the first client connect, and a cache rehash during a later validation call. Verified both new suppression stanzas match their respective captured stack traces frame-for-frame and do not cross-match each other. Signed-off-by: Jonathan Neufeld <jonathan.neufeld@improving.com>
Add optional client_info_tag and lib_name connection options that customize the library identity sent to the server via CLIENT SETINFO LIB-NAME, for standalone, cluster, monitor, and mock-constructor clients. - lib_name overrides the reported library name (default: GlidePHP). client_info_tag appends a parenthesised suffix for framework attribution, composing as "<lib_name>(<tag>)". An empty string or null on either field is treated as UNSET (yielding the default, adding no "(tag)" suffix), matching glide-core's is_empty()-as-absent semantics. - Per-field charset validation (^[\x21-\x27\x2A-\x7E]+$: printable ASCII excluding space and parentheses) is byte-for-byte identical to glide-core's validate_effective_lib_name() per-field class, verified by a falsifiable 0x01-0xFF parity sweep (testMetadataCharsetParityWithGlideCore). Kept as an approved deviation from core-only validation so an invalid value's error can name the offending field (lib_name vs client_info_tag), which core -- validating only the composed name -- cannot do. Parentheses are excluded per field because the binding itself introduces the only permitted "(tag)" pair when composing. - The composed name is resolved by a single pure function (valkey_glide_resolve_lib_name) shared by every entry point -- standalone, cluster, monitor, and the test mock constructors -- so accept/reject behaviour and the resulting identity cannot drift between them. - Submodule bumped to 49f2b6d21 (upstream glide-core commit 0e02ff973 / PR #6891, validate_effective_lib_name). Fixes: macOS -Werror collision between glide's NSEC_PER_SEC/NSEC_PER_MSEC macros and mach/clock_types.h SDK definitions, by adopting project-prefixed VALKEY_GLIDE_NSEC_PER_SEC/MSEC names. Adds a valgrind.supp suppression for glide-core's LIB_NAME_PATTERN lazy DFA cache allocation, a process-lifetime regex-automata cache that is never freed before process exit by design (0 bytes definitely/indirectly lost), matching the file's existing DashMap/OnceLock suppression patterns for the same class of process-lifetime singleton. Tests: ConnectionRequestTest, ValkeyGlideFeaturesTest, ValkeyGlideClusterFeaturesTest, and ValkeyGlideMonitorTest cover charset validation, empty-as-absent behaviour, composition across all four client-construction entry points, and parity against glide-core's grammar.

Summary
Adds two new parameters to
ValkeyGlide::connect()andValkeyGlideCluster::__construct():lib_name— overrides theCLIENT SETINFO LIB-NAMEvalue. When unset, Rust core default (GlidePHP) is preserved.client_info_tag— appends a parenthesized tag to the resolved library name, e.g.GlidePHP(my-framework:1.0). Follows the ioredis convention for framework attribution.Closes tracking for PHP parity with valkey-io/valkey-glide#6389 (Python implementation).
