- Improvement: Fixed issue where oplog upload could create blocks larger than the max limit (64Mb)
Refactored remoteprojectstore.cpp to use ParallelWork and exceptions for error handling.

* create oplogs as they are imported
* Improved logic for partial block analisys
* unit tests for ChunkBlockAnalyser

- **Frontend dashboard overhaul**: Unified compute/main dashboards into a single shared UI. Added new pages for cache, projects, metrics, sessions, info (build/runtime config, system stats). Added live-update via WebSockets with pause control, sortable detail tables, themed styling. Refactored compute/hub/orchestrator pages into modular JS.
- **HTTP server fixes and stats**: Fixed http.sys local-only fallback when default port is in use, implemented root endpoint redirect for http.sys, fixed Linux/Mac port reuse. Added /stats endpoint exposing HTTP server metrics (bytes transferred, request rates). Added WebSocket stats tracking.
- **OTEL/diagnostics hardening**: Improved OTLP HTTP exporter with better error handling and resilience. Extended diagnostics services configuration.
- **Session management**: Added new sessions service with HTTP endpoints for registering, updating, querying, and removing sessions. Includes session log file support. This is still WIP.
- **CLI subcommand support**: Added support for commands with subcommands in the zen CLI tool, with improved command dispatch.
- **Misc**: Exposed CPU usage/hostname to frontend, fixed JS compact binary float32/float64 decoding, limited projects displayed on front page to 25 sorted by last access, added vscode:// link support.
Also contains some fixes from TSAN analysis.

Removes the vendored spdlog library (~12,000 lines) and replaces it with a purpose-built logging system in zencore (~1,800 lines). The new implementation provides the same functionality with fewer abstractions, no shared_ptr overhead, and full control over the logging pipeline.
### What changed
**New logging core in zencore/logging/:**
- LogMessage, Formatter, Sink, Logger, Registry - core abstractions matching spdlog's model but simplified
- AnsiColorStdoutSink - ANSI color console output (replaces spdlog stdout_color_sink)
- MsvcSink - OutputDebugString on Windows (replaces spdlog msvc_sink)
- AsyncSink - async logging via BlockingQueue worker thread (replaces spdlog async_logger)
- NullSink, MessageOnlyFormatter - utility types
- Thread-safe timestamp caching in formatters using RwLock
**Moved to zenutil/logging/:**
- FullFormatter - full log formatting with timestamp, logger name, level, source location, multiline alignment
- JsonFormatter - structured JSON log output
- RotatingFileSink - rotating file sink with atomic size tracking
**API changes:**
- Log levels are now an enum (LogLevel) instead of int, eliminating the zen::logging::level namespace
- LoggerRef no longer wraps shared_ptr - it holds a raw pointer with the registry owning lifetime
- Logger error handler is wired through Registry and propagated to all loggers on registration
- Logger::Log() now populates ThreadId on every message
**Cleanup:**
- Deleted thirdparty/spdlog/ entirely (110+ files)
- Deleted full_test_formatter (was ~80% duplicate of FullFormatter)
- Renamed snake_case classes to PascalCase (full_formatter -> FullFormatter, json_formatter -> JsonFormatter, sentry_sink -> SentrySink)
- Removed spdlog from xmake dependency graph
### Build / test impact
- zencore no longer depends on spdlog
- zenutil and zenvfs xmake.lua updated to drop spdlog dep
- zentelemetry xmake.lua updated to drop spdlog dep
- All existing tests pass, no test changes required beyond formatter class renames

Various fixes to make cpp files build in unity build mode
as an aside using Unity build doesn't really seem to work on Linux, unsure why but it leads to link-time issues

- Improvement: `zen builds download` now uses multi-range requests for blocks to reduce download size
- Improvement: `zen oplog-import` now uses partial block with multi-range requests for blocks to reduce download size
- Improvement: Improved feedback in log/console during `zen oplog-import`
- Improvement: `--allow-partial-block-requests` now defaults to `true` for `zen builds download` and `zen oplog-import` (was `mixed`)
- Improvement: Improved range merging analysis when downloading partial blocks
|

Feature: Add --allow-partial-block-requests to zen oplog-import
Improvement: zen oplog-import now uses partial block requests to reduce download size
Improvement: Use latency to Cloud Storage host and Zen Cache host when calculating partial block requests

- Improvement: Validate chunk hashes when dechunking files in oplog import
- Improvement: Use stream decompression when dechunking files
- Improvement: When assembling blocks for oplog export, make sure we keep under/at block size limit
- Improvement: Make cancelling of oplog import more responsive
- Improvement: Use decompress to composite to avoid allocating a new memory buffer for uncompressed chunks during oplog import
- Improvement: Reduce memory buffer size and allocate it on demand when writing multiple chunks to block store
- Improvement: Reduce lock contention when fetching/checking existence of chunks in block store
|

|
| |
|
|
| |
- Bugfix: Upload of oplogs could reference multiple blocks for the same chunk causing redundant downloads of blocks
- Improvement: Use the improved block reuse selection function from zen builds upload in zen oplog-export to reduce oplog download size

- Improvement: Deeper validation of data when scrub is activated (cas/cache/project)
- Improvement: Enabled more multi threading when running scrub operations
- Improvement: Added means to force a scrub operation at startup with a new release using ZEN_DATA_FORCE_SCRUB_VERSION variable in xmake.lua

effective concurrency in zenserver can be limited via the `--corelimit=<N>` option on the command line. Any value passed in here will be used instead of the return value from `std::thread::hardware_concurrency()` if it is lower.
* added --corelimit option to zenserver
* made sure thread pools are configured lazily and not during global init
* added log output indicating effective and HW concurrency
* added change log entry
* removed debug logging from ZenEntryPoint::Run()
also removed main thread naming on Linux since it makes the output from `top` and similar tools confusing (it shows `main` instead of `zenserver`)
