* updated chunk–block analyser (#818)Dan Engelbrecht2026-03-091-40/+3
| | | | | * create oplogs as they are imported * Improved logic for partial block analisys * unit tests for ChunkBlockAnalyser
* Dashboard overhaul, compute integration (#814)Stefan Boberg2026-03-091-0/+1
| | | | | | | | | | - **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.

* Eliminate spdlog dependency (#773)Stefan Boberg2026-03-091-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* zenstore bug-fixes from static analysis pass (#815)Stefan Boberg2026-03-064-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | **Bug fixes across zenstore, zenremotestore, and related subsystems, primarily surfaced by static analysis.** ## Cache subsystem (cachedisklayer.cpp) - Fixed tombstone scoping bug: tombstone flag and missing entry were recorded outside the block where data was removed, causing non-missing entries to be incorrectly tombstoned - Fixed use-after-overwrite: `RemoveMemCachedData`/`RemoveMetaData` were called after `Payload` was overwritten on cache put, leaking stale data - Fixed incorrect retry sleep formula (`100 - (3 - RetriesLeft) * 100` always produced the same or negative value; corrected to `(3 - RetriesLeft) * 100`) - Fixed broken `break` missing from sidecar file read loop, causing reads past valid data - Fixed missing format argument in three `ZEN_WARN`/`ZEN_ERROR` log calls (format string had `{}` placeholders with no corresponding argument, or vice versa) - Fixed elapsed timer being accumulated inside the wrong scope in `HandleRpcGetCacheRecords` - Fixed test asserting against unserialized `RecordPolicy` instead of the deserialized `Loaded` copy - Initialized `AbortFlag`/`PauseFlag` atomics at declaration (UB if read before first write) ## Build store (buildstore.cpp / buildstore.h) - Fixed wrong variable used in warning log: used loop index `ResultIndex` instead of `Index`/`MetaLocationResultIndexes[Index]`, logging wrong hash values - Fixed `sizeof(AccessTimesHeader)` used instead of `sizeof(AccessTimeRecord)` when advancing write offset, corrupting the access times file if the sizes differ - Initialized `m_LastAccessTimeUpdateCount` atomic member (was uninitialized) - Changed map iteration loops to use `const auto&` to avoid unnecessary copies ## Project store (projectstore.cpp / projectstore.h) - Fixed wrong iterator dereferenced in `IterateChunks`: used `ChunkIt->second` (from a different map lookup) instead of `MetaIt->second` - Fixed wrong assert variable: `Sizes[Index]` should be `RawSizes[Index]` - Fixed `MakeTombstone`/`IsTombstone` inconsistency: `MakeTombstone` was zeroing `OpLsn` but `IsTombstone` checks `OpLsn.Number != 0`; tombstone creation now preserves `OpLsn` - Fixed uninitialized `InvalidEntries` counter - Fixed format string mismatch in warning log - Initialized `AbortFlag`/`PauseFlag` atomics; changed map iteration to `const auto&` ## Workspaces (workspaces.cpp) - Fixed missing alias registration when a workspace share is updated: alias was deleted but never re-inserted - Fixed integer overflow in range clamping: `(RequestedOffset + RequestedSize) > Size` could wrap; corrected to `RequestedSize > Size - RequestedOffset` - Changed map iteration loops to `const auto&` ## CAS subsystem (cas.cpp, caslog.cpp, compactcas.cpp, filecas.cpp) - Fixed `IterateChunks` passing original `Payload` buffer instead of the modified `Chunk` buffer (content type was set on the copy but the original was sent to the callback) - Fixed invalid `std::future::get()` call on default-constructed futures - Fixed sign-comparison in `CasLogFile::Replay` loop (`int i` vs `size_t`) - Changed `CasLogFile::IsValid` and `Open` to take `const std::filesystem::path&` instead of by value - Fixed format string in `~CasContainerStrategy` error log ## Remote store (zenremotestore) - Fixed `FolderContent::operator==` always returning true: loop variable `PathCount` was initialized to 0 instead of `Paths.size()` - Fixed `GetChunkIndexForRawHash` looking up from wrong map (`RawHashToSequenceIndex` instead of `ChunkHashToChunkIndex`) - Fixed double-counted `UniqueSequencesFound` stat (incremented in both branches of an if/else) - Fixed `RawSize` sentinel value truncation: `(uint32_t)-1` assigned to a `uint64_t` field; corrected to `(uint64_t)-1` - Initialized uninitialized atomic and struct members across `buildstorageoperations.h`, `chunkblock.h`, and `remoteprojectstore.h`

* allow download specification for zen builds download (#734)Dan Engelbrecht2026-01-272-13/+30
| | | | | | | | | | | | | | | | | | | | | - Feature: `zen builds download` now supports `--download-spec-path` to determine what content to download from a build - The unstructured format expects one line per file relative to the root with '/' as a path delimiter - The structured format uses JSon format and the `--download-spec-path` must have extension `.json` to enable structured input { "parts": { "default" : { "files": [ "foo/bar", "baz.exe" ] }, "symbols": { "files": [ "baz.pdb" ] } } }

* | Ensure upstream put propagation includes overwritezousar2025-12-191-1/+6
|/ | | | When changing the default limit-overwrite behavior, a unit test surfaced a bug where an put of data with overwrite cache policy would not get propagated via zen's built-in upstream mechanism with a matching overwrite cache policy to the upstream. This change ensures that it does and leaves the unit test configured to exercise this scenario.
* add boost-worker oplog import export options (#693)Dan Engelbrecht2025-12-163-3/+57
| | | | | | | | | | - Feature: `zen oplog-export`, `zen oplog-import` and `zen oplog-download` now has options to boost workers - `--boost-worker-count` - Increase the number of worker threads - may cause computer to be less responsive - `--boost-worker-memory` - Increase the limit where we write downloaded data to temporary storage to conserve space - may cause computer to be less responsive due to high memory usage - `--boost-workers` - Enables both 'boost-worker-count' and 'boost-worker-memory' - may cause computer to be less responsive - Improvement: Refactored boost options for `zen builds` operations `upload`, `download`, `diff`, `prime-cache`, `fetch-blob` and `validate-part` - `--boost-worker-count` - Increase the number of worker threads - may cause computer to be less responsive - `--boost-worker-memory` - Increase the limit where we write downloaded data to temporary storage to conserve space - may cause computer to be less responsive due to high memory usage - `--boost-workers` - Enables both 'boost-worker-count' and 'boost-worker-memory' - may cause computer to be less responsive
* oplog download size (#690)Dan Engelbrecht2025-12-153-27/+39

* Change curl defaults on MacOS (#645)Stefan Boberg2025-11-113-3/+4
| | | | | | | * changed curl config to match the default from vcpkg (i.e `CURL_CA_FALLBACK=ON`) * disables use of Secure Transport for Mac since it's deprecated * Also worked around an issue (with `CURL_CA_BUNDLE`) where cross compiling curl on Mac would not configure curl in the same way as when compiling natively. This meant builds would not download on ARM macs when the CI build machine architecture was x86. The workaround should be redundant if we upgrade to 8.17 and use Apple SecTrust for cert validation. This should happen soon. * Also added various verbose logging to facilitate trouble shooting
