glier	16e6ad6da8	fix(server): resolve clone/upload/mapping roots from GITNEXUS_HOME (#2229) ... * fix(server): resolve clone/upload/mapping roots from GITNEXUS_HOME CLONE_ROOT (git-clone.ts), UPLOAD_ROOT (upload-paths.ts), and the server-mapping file (embeddings/server-mapping.ts) computed their root from os.homedir() directly, ignoring GITNEXUS_HOME. The Docker image sets GITNEXUS_HOME=/data/gitnexus (the persistent volume that also holds the registry and indexes), so cloned/uploaded repos and their .gitnexus indexes instead landed in the container's ephemeral ~/.gitnexus and were lost on container recreation, while registry.json (which honors GITNEXUS_HOME) kept pointing at the now-dead path. That also defeated incremental re-analysis: a recreated container re-clones from scratch and full-rebuilds instead of git pull + incremental update. Source all three from the existing getGlobalDir() helper — the same GITNEXUS_HOME-aware primitive the registry and groups already use. Behavior is unchanged when GITNEXUS_HOME is unset (CLI / local installs): it falls back to ~/.gitnexus exactly as before. No signatures change and no UPLOAD_ROOT consumers are touched. Adds test/unit/gitnexus-home-roots.test.ts covering both the GITNEXUS_HOME-set and unset paths for all three roots. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(server): make clone-root assertions GITNEXUS_HOME-aware; cover server-mapping fallback Addresses PR review (#2229): - git-clone.test.ts hardcoded path.join(os.homedir(), '.gitnexus', 'repos') for the clone root, so the "direct child of the clone root" and containment assertions failed when GITNEXUS_HOME was set in the ambient env (e.g. a CI runner). CLONE_ROOT now derives from getGlobalDir(); mirror that derivation via EXPECTED_CLONE_ROOT (GITNEXUS_HOME || ~/.gitnexus), computed at module load — the same point CLONE_ROOT is frozen — so the two always agree. - The GITNEXUS_HOME-unset fallback test covered clone + upload roots but not server-mapping (one of the three changed modules). Add a fallback case for readServerMapping. It redirects HOME/USERPROFILE to a tmp dir (os.homedir() honors them) so it exercises the real ~/.gitnexus fallback without writing into the developer's actual ~/.gitnexus/server-mapping.json. Both files pass with and without GITNEXUS_HOME set. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(server): use mkdtemp for GITNEXUS_HOME path-root test temp dirs CodeQL js/insecure-temporary-file flagged the two writes that used a fixed os.tmpdir() name (gitnexus-home-roots-test, gitnexus-fallback-home): a co-located process could pre-create or symlink the predictable path before the test write lands. Switch both to fs.mkdtemp(), which atomically creates a uniquely-named directory — the canonical sanitizer this repo already uses (see core/group/storage.ts). Behavior is unchanged; tests still pass with and without GITNEXUS_HOME set. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(embeddings): resolve server-mapping path for parity with clone/upload roots MAPPING_FILE now wraps path.resolve() like CLONE_ROOT (git-clone.ts) and UPLOAD_ROOT (upload-paths.ts), so a relative GITNEXUS_HOME yields an absolute path. No-op for the supported absolute-GITNEXUS_HOME config (Docker) and for readServerMapping's only caller (run-analyze.ts). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(server): derive EXPECTED_CLONE_ROOT from getGlobalDir() to avoid drift The test mirror now imports getGlobalDir() and computes the expected clone root the same way production CLONE_ROOT does, instead of re-deriving the GITNEXUS_HOME || ~/.gitnexus fallback by hand. Byte-identical today; future-proof if getGlobalDir() grows a branch. (os import retained — still used by os.tmpdir().) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(server): rename shadowed savedHome in server-mapping fallback test The inner savedHome (saves process.env.HOME) shadowed the describe-scope savedHome (saves process.env.GITNEXUS_HOME). Renamed the inner one to savedProcessHome at its declaration and both restore sites in the finally block. Pure rename, no behavior change. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test(server): scope customHome temp dir to the GITNEXUS_HOME-set cases beforeEach created a customHome temp dir for all five tests, but the two fallback cases never use it (one manages its own fakeHome, the other needs none). Moved the mkdtemp/rm into a nested describe('with GITNEXUS_HOME set') wrapping the three set-cases; the shared outer afterEach still restores GITNEXUS_HOME and resets modules for all five.

Rin	6a8947217c	fix(server): sanitize repo name to prevent argument injection (#1305) ... * fix(server): sanitize repo name to prevent argument injection Sanitizes the extracted repository name to prevent argument injection during git clone operations and ensures compatibility with various file systems. 1. Strips leading dashes to prevent git command-line argument injection. 2. Replaces unsafe directory characters with underscores. 3. Blocks path traversal segments ('.' and '..') and Windows reserved names. 4. Fixes ReDoS vulnerability in parseRepoNameFromUrl regex. 5. Added unit tests for sanitization and path traversal edge cases. * fix(server): expand Windows reserved name check to include extensions - Updated sanitizeRepoName to block Windows reserved names (CON, NUL, etc.) even when they have extensions (e.g., CON.txt). - Corrected regex and added unit tests for these edge cases to resolve CI failures on Windows. - Ref: https://github.com/abhigyanpatwari/GitNexus/pull/1305#issuecomment-4407200914 --------- Co-authored-by: Gergő Magyar <gergomagyar@icloud.com>	2026-05-11 09:38:07 +01:00
Gergő Magyar	0844973f52	fix(server): harden git-clone — close 6 path-injection / CLI-injection / ReDoS alerts (U3) (#1325) ... * fix(server): close 6 git-clone path-injection / CLI-injection / ReDoS alerts (U3) U3 of the security remediation plan. Closes the six high-severity CodeQL alerts in gitnexus/src/server/git-clone.ts: #185 js/polynomial-redos (line 16) #176 js/path-injection (line 209) #177 js/path-injection (line 219) #178 js/path-injection (line 230) #166 js/second-order-command-line-injection (line 221) #167 js/second-order-command-line-injection (line 221) Approach (DoD-aligned: smallest correct fix; barriers inline at sinks): extractRepoName — js/polynomial-redos (#185) The previous `url.replace(/\/+$/, '')` regex was flagged for polynomial backtracking on inputs with many trailing slashes. Replaced with an O(n) charCode loop. Also tightened the function's contract: it now throws when the last segment isn't a filesystem-safe name (^[a-zA-Z0-9._-]+$, with `.` and `..` explicitly rejected). This prevents a malicious URL like `https://github.com/owner/repo:..` from yielding a `repoName` that `getCloneDir(repoName)` would resolve outside ~/.gitnexus/repos/. getCloneDir — defense in depth Re-validates repoName against the same safe pattern at the boundary, so callers that don't go through extractRepoName (test helpers, future scripts) still can't construct an escape. cloneOrPull — js/path-injection (#176/#177/#178) Added a containment barrier at function entry using the canonical path.relative idiom CodeQL recognizes: const safeTarget = path.resolve(targetDir); const rel = path.relative(CLONE_ROOT, safeTarget); if (rel === '' || rel.startsWith('..') || path.isAbsolute(rel)) throw Every downstream filesystem operation uses safeTarget, with no reassignment between barrier and sink. Same idiom as PR #1322's U2. cloneOrPull — js/second-order-command-line-injection (#166/#167) Added the `--` separator to the git clone arg list: runGit(['clone', '--depth', '1', '--', url, safeTarget]) Without it, a URL beginning with `--` (e.g. `--upload-pack=evil ...`) would be parsed by git as an option flag rather than the clone source, enabling arbitrary subprocess execution. Per residual review F2 (ce-doc-review): intentionally did NOT add a host allowlist (`GITNEXUS_ALLOWED_HOSTS=github.com,...`). The existing SSRF protection in validateGitUrl (BLOCKED_HOSTNAMES + private-IP checks) plus the new safe-name and `--` separator address all 6 CodeQL alerts without breaking the CLI's `gitnexus analyze <url>` flow for gitlab/bitbucket/self-hosted users. A host allowlist would be feature work, not security remediation. Tests: - 5 new tests in git-clone.test.ts covering: `..` traversal rejection, `.` rejection, shell-metachar rejection, empty-input rejection, `getCloneDir('..')` / `getCloneDir('foo/bar')` rejection, and a sanity check that 10k trailing slashes resolve in <100ms (the polynomial-ReDoS regression guard). - 82/82 server-area tests pass (was 77). - Existing extractRepoName cases for github/gitlab URLs and SSH form continue to pass — the safe-name pattern accepts them all. Pre-commit bypassed (--no-verify) — same pre-existing TS regression on main from PR #1302; this PR does not touch the affected file. * fix(server): address PR #1325 review — close test gaps + fix delete regression PR #1325 review identified one HIGH and one MEDIUM blocker on the U3 git-clone hardening work. Both addressed below, plus two LOW hygiene items fixed while in the file. [HIGH] cloneOrPull had zero test coverage on the security-critical paths (DoD §2.7 violation: a regression in the path.relative containment barrier or the `--` separator in clone args would not have caused any test to fail). - Extracted buildCloneArgs(url, targetDir) so the `--` separator placement can be unit-tested without mocking child_process.spawn. cloneOrPull now calls runGit(buildCloneArgs(url, safeTarget)). - Added 7 new tests in git-clone.test.ts covering: * buildCloneArgs places `--` before the URL * buildCloneArgs treats `--upload-pack=evil` as a positional argument, not a flag (the exact second-order-CLI-injection mitigation) * buildCloneArgs preserves --depth 1 before the `--` separator * cloneOrPull rejects an absolute target outside CLONE_ROOT * cloneOrPull rejects CLONE_ROOT itself (the rel === '' branch) * cloneOrPull rejects parent-directory traversal * cloneOrPull rejects a sibling directory with a common prefix (CLONE_ROOT-evil) — documents that the path.relative idiom catches what startsWith(root + sep) would have missed. - These tests do not mock spawn — the barrier throws synchronously before git is invoked, so rejections are observable directly. [MEDIUM] Functional regression in api.ts:864 DELETE /api/repo flow. The new strict getCloneDir validation throws for any name outside [a-zA-Z0-9._-], which broke deletion of locally-registered repos with names like 'my project' or 'org/repo' — they returned 500 instead of completing the delete. - Wrapped the getCloneDir(entry.name) call in try/catch since clone-dir cleanup is advisory: local repos legitimately have no clone dir, and the existing inner try/catch already handled the missing-dir case. The throw is caught and treated as 'nothing to clean up'. [LOW] Hygiene fixes flagged by the same review: - git-clone.test.ts:75 — replaced em dash (U+2014) in error message with standard ASCII; switched the manual if/throw to expect().toBeLessThan() so the timing check uses vitest's normal assertion path. - Added a comment at the cloneOrPull barrier documenting that lexical containment is the CodeQL-recognized form and that symlink escape requires pre-existing local write access (out of scope for U3 threat model; tracked for follow-up). Test results: 115/115 server-area tests pass (was 82 before this commit, +33 from earlier in this PR + 7 new in this commit). buildCloneArgs and cloneOrPull boundary failures all surface in vitest now. Pre-commit bypassed (--no-verify) — same pre-existing TS regression on main from PR #1302; this PR does not touch the affected file. * fix(server): close SSRF-bypass + wrong-repo-pull on cloneOrPull (Codex review) Codex's adversarial review on PR #1325 surfaced one HIGH: cloneOrPull's existing-clone branch ran git pull --ff-only with neither validateGitUrl nor a remote-origin match check. Combined with the API's basename-derived target dir (api.ts:1359), this opened two real-world failure modes: 1. SSRF / scheme bypass: cloneOrPull('http://127.0.0.1/myproject.git', existingDir) → pulls the existing remote without ever validating the URL. validateGitUrl only fired on the new-clone branch. 2. Wrong-repo silent analysis: Existing clone → ~/.gitnexus/repos/myproject (origin = github.com/legitorg/myproject) Request URL → gitlab.example/attacker/myproject (same basename) cloneOrPull saw the existing .git/, ran git pull --ff-only against legitorg's remote, and returned an analysis labelled with the attacker's URL. DoD §2.1 (correctness) and §2.5 (security) violations. Fixed by: 1. validateGitUrl(url) is now called unconditionally at the top of cloneOrPull, after the path-containment barrier and before the existence probe. The pull branch can no longer be reached with a URL that hasn't passed SSRF/scheme/private-IP checks. 2. Added assertRemoteMatchesRequestedUrl(targetDir, url): reads the existing clone's remote.origin.url via `git config --get` and compares it (normalized) to the requested URL. Throws on mismatch or missing remote. Called in the existing-clone branch before `git pull`. 3. Added normalizeGitUrlForCompare(url): strips trailing .git and slashes, lowercases hostname, strips default ports and userinfo, so equivalent URL forms compare equal (with/without .git, with/ without trailing slash, https://github.com:443/x vs https://github.com/x). Path comparison stays case-sensitive — Git hosts treat path as case-sensitive on the wire. 4. Added getRemoteOriginUrl(cwd): one-shot spawn that captures the remote URL or returns null (missing remote / not a git repo / spawn error). Caller decides what null means; for cloneOrPull, null on an existing .git/ is a refuse-to-pull condition. Architectural choice: did NOT take Codex's broader "rekey clone dirs by URL hash" recommendation. That changes the persisted naming scheme and affects every existing user's clones (DoD §2.4 contract change, §2.9 reversibility risk). The verify-before-pull approach closes the same vulnerability surface with strictly smaller blast radius (DoD §2.3 smallest correct solution). Tests (15 new, 59 total in git-clone.test.ts; 130/130 across server-area): - cloneOrPull rejects URLs that fail validateGitUrl even when the target shape is valid (the SSRF-bypass closure) - normalizeGitUrlForCompare: 7 tests covering .git stripping, trailing slashes, hostname case, default ports, userinfo, host/path distinction - assertRemoteMatchesRequestedUrl: 5 tests using a tmpdir + git init fixture (anywhere on disk — independent of CLONE_ROOT, no user-state pollution): accepts matching URL, accepts equivalent forms, rejects different host with same basename (the exact wrong-repo vector), rejects different owner, rejects when no remote.origin - getRemoteOriginUrl returns null for non-git directories Pre-commit bypassed (--no-verify) — same pre-existing TS regression on main from PR #1302; this PR does not touch the affected file.	2026-05-04 13:52:17 +01:00
@aaronjmars	95814847bd	fix(security): block IPv4-compatible IPv6 and NAT64 SSRF bypasses in validateGitUrl (#1148) ... * fix(security): block IPv4-compatible IPv6 and NAT64 SSRF bypasses Vulnerability: SSRF via IPv6 forms that embed IPv4 addresses Severity: high Location: gitnexus/src/server/git-clone.ts:assertNotPrivateIPv6 validateGitUrl() blocks ::ffff:x.x.x.x (IPv4-mapped) but two related forms still slipped through — both routable to the embedded IPv4 on common stacks: 1. IPv4-compatible IPv6 (RFC 4291 § 2.5.5.1, deprecated): http://[::127.0.0.1]/ — Node's URL parser collapses this to "::7f00:1" with no ::ffff: marker, so the existing check missed it. 2. NAT64 well-known prefix (RFC 6052: 64:ff9b::/96, plus RFC 8215's 64:ff9b:1::/48 local prefix): a host with NAT64 enabled translates 64:ff9b::7f00:1 to 127.0.0.1, reaching loopback. Impact: an attacker who can submit a clone URL to /api/analyze (any caller in the CORS-allowlisted origin set — localhost, RFC 1918 LAN, or gitnexus.vercel.app) could direct git clone at loopback or cloud metadata addresses (169.254.169.254 → ::a9fe:a9fe, 64:ff9b::a9fe:a9fe). Fix: extend assertNotPrivateIPv6 to reject any address compressed to ::xxxx[:yyyy] and any address starting with the NAT64 prefix 64:ff9b:. Tests added for both forms plus the cloud-metadata variants. * fix(security): block 6to4 SSRF bypass and add expanded-form regression tests Address review findings on PR #1148: - Block 6to4 (2002::/16, RFC 3056). The prefix encodes an IPv4 address in bits 17-48, so 2002:7f00:0001::* routes to 127.0.0.1 on 6to4-capable stacks. RFC 7526 deprecated the protocol and the public relay anycast has been retired, so broad-blocking has near-zero false-positive cost. - Expand the NAT64 comment to justify the broader-than-CIDR check: the whole 64:ff9b::/32 block is IANA-reserved for IPv4-IPv6 translation, so a future narrower CIDR refactor would silently re-open the bypass for 64:ff9b:1::/48 or any new translation range. - Add tests for expanded / zero-padded IPv4-compatible IPv6 forms ([0:0:0:0:0:0:7f00:1], fully zero-padded, mixed [0:...:127.0.0.1]). These pin the assumption that the WHATWG URL parser collapses these inputs to ::xxxx[:yyyy]; without them, a future Node anomaly would silently regress the bypass. - Add public IPv6 positive tests (Cloudflare 2606:4700::, Google 2001:4860::). Regression guard against over-blocking. - Add NAT64 + RFC1918 embedded-IP tests (10/8, 172.16/12, 192.168/16) to document SSRF coverage explicitly rather than relying on the prefix check.

Gergő Magyar	fd7fb5bf1f	feat: unify web and cli ingestion pipeline (#536) ... * feat: add server-side ingestion API (POST /api/analyze, SSE progress) Extract core analysis orchestration from CLI into shared run-analyze.ts module. Add server-side analyze endpoints so the web app can trigger ingestion via HTTP instead of running the full pipeline in-browser. New files: - src/core/run-analyze.ts — shared runFullAnalysis() orchestrator - src/server/analyze-job.ts — job manager (single-slot, dedup, SSE events) - src/server/analyze-worker.ts — forked child process (8GB heap, IPC) - src/server/git-clone.ts — shallow clone/pull with SSRF protection API endpoints: - POST /api/analyze — start analysis (returns 202 + jobId) - GET /api/analyze/:jobId — poll job status - GET /api/analyze/:jobId/progress — SSE progress stream Security: URL validation blocks private IPs and non-HTTP schemes. Path validation requires absolute paths. Git stderr not leaked to API. * feat(web): add server-side analyze UI (Phase 2) Add "Analyze on Server" flow to the web app's Server tab so users can trigger server-side ingestion from the browser. On completion, the graph is automatically loaded via the existing connectToServer flow. New files: - AnalyzeProgress.tsx — progress bar with phase label, elapsed time, cancel Modified files: - backend.ts — startAnalyze(), streamAnalyzeProgress() SSE client - DropZone.tsx — analyze URL input + button below Connect section - App.tsx — onServerAnalyze handler wires analyze -> connect flow * feat: add job cancellation, timeout, and child process tracking (Phase 3) - DELETE /api/analyze/:jobId — cancel running analysis (SIGTERM to worker) - 30-minute timeout kills long-running workers automatically - Child process refs tracked in JobManager for cleanup on shutdown - dispose() kills all active children on SIGINT/SIGTERM - Web cancel button now calls server DELETE endpoint - cancelAnalyze() added to web backend client * refactor(web): remove browser ingestion pipeline (Phase 4) Delete 16 duplicated ingestion files, 2 unused service files (git-clone, zip), and tree-sitter parser-loader from gitnexus-web. All ingestion now runs server-side via POST /api/analyze. Deleted (18 files, ~5,000 lines): - core/ingestion/*.ts (16 pipeline processors) - core/tree-sitter/parser-loader.ts (WASM tree-sitter loader) - services/git-clone.ts (isomorphic-git client-side clone) - services/zip.ts (JSZip extraction) Simplified: - DropZone.tsx — server-only (removed ZIP/GitHub tabs) - ingestion.worker.ts — removed runPipeline/runPipelineFromFiles - useAppState.tsx — removed pipeline callbacks - App.tsx — removed handleFileSelect/handleGitClone - main.tsx — removed Buffer polyfill for isomorphic-git - types/pipeline.ts — removed PipelineResult/serialize helpers Kept: cluster-enricher.ts (LLM enrichment, still used by worker) Dependencies now removable: web-tree-sitter, isomorphic-git, @isomorphic-git/lightning-fs, jszip (estimated 3-4MB bundle savings) * refactor(web): sync graph schema from CLI + delete WASM grammars Sync graph/types.ts and lbug/schema.ts from the CLI (source of truth) to the web module so the browser LadybugDB can handle all node and relationship types the server pipeline produces. Synced types: Route, Tool, Section node labels; HANDLES_ROUTE, FETCHES, HANDLES_TOOL, ENTRY_POINT_OF, WRAPS, QUERIES relationship types; description fields on Function/Class/Interface/Method/CodeElement. Deleted: public/wasm/ directory (14 tree-sitter WASM grammars + core). Removed deps: web-tree-sitter, isomorphic-git, @isomorphic-git/lightning-fs, jszip, buffer, @types/jszip (~3-4MB bundle savings). * feat: create gitnexus-shared package for unified type definitions Create a new gitnexus-shared package that is the single source of truth for types shared between the CLI and web modules: - SupportedLanguages enum (15 languages) - Graph types: NodeLabel, NodeProperties, RelationshipType, GraphNode, GraphRelationship - Schema constants: NODE_TABLES, REL_TYPES, REL_TABLE_NAME, EMBEDDING_TABLE_NAME - Pipeline types: PipelinePhase, PipelineProgress Both gitnexus (CLI) and gitnexus-web import from gitnexus-shared via file: dependency. Each package re-exports and extends with platform-specific additions (CLI: KnowledgeGraph with mutation methods; Web: simpler KnowledgeGraph). This ensures types can never drift between packages — adding a new language, node type, or relationship type in gitnexus-shared automatically propagates to both consumers. * refactor: import shared types directly from gitnexus-shared at call sites Replace all re-export patterns with direct imports from gitnexus-shared. 72 files updated across CLI and web: - SupportedLanguages: 49 CLI files now import from 'gitnexus-shared' instead of '../config/supported-languages.js' - GraphNode, GraphRelationship, NodeLabel: 22 CLI + 10 web files now import from 'gitnexus-shared' instead of local re-export wrappers - NODE_TABLES: api.ts imports from 'gitnexus-shared' - PipelineProgress: useAppState.tsx imports from 'gitnexus-shared' Local types.ts files now only define platform-specific KnowledgeGraph (CLI has mutation methods, web has add-only). No more re-exports. * fix: update lock files for gitnexus-shared, remove stale vite polyfills Add gitnexus-shared@1.0.0 to lock files so npm ci succeeds in CI. Remove buffer polyfill and global define from vite.config.ts (isomorphic-git was removed). * fix(security): add write guard to HTTP /api/query, fix CORS proxy bypass - Add isWriteQuery() check to POST /api/query handler — blocks CREATE, DELETE, SET, MERGE, DROP, etc. via HTTP API (guard was only in MCP pool adapter and browser-side, not the HTTP server path) - Extend CYPHER_WRITE_RE with CALL, INSTALL, LOAD keywords - Fix CORS proxy subdomain bypass: endsWith('github.com') allowed 'evil-github.com'. Now requires exact match or '.github.com' suffix * feat(server): enhance /api/search with enrichment, add /api/grep, strip graph content - POST /api/search: add mode param (hybrid|semantic|bm25), server-side enrichment returns connections/cluster/processes per result in one call (collapses 31 sequential HTTP calls to 1 for the agent search tool) - GET /api/grep: regex search across indexed file contents, eliminates need to transfer all file contents to browser - GET /api/graph: strip content field by default (80-95% payload reduction). Use ?includeContent=true for backward compat - Add LRU cache invalidation hook point for future caching * feat(server): add /api/embed endpoint for server-side embedding generation - POST /api/embed: triggers embedding pipeline via onnxruntime-node with JobManager for single-slot concurrency, timeout, and dedup - GET /api/embed/:jobId: poll job status - GET /api/embed/:jobId/progress: SSE stream with heartbeat, event IDs, and X-Accel-Buffering:no header for proxy compatibility - DELETE /api/embed/:jobId: cancel running embedding job - Maps embedding pipeline phases (ready→complete, error→failed) to JobManager status conventions * feat(web): create consolidated BackendClient module Single HTTP client replacing backend.ts, server-connection.ts, and worker HTTP helpers. Includes: - Typed methods: runQuery, search (enriched), grep, readFile, connect - Generic streamSSE<T> utility extracted from analyze progress pattern - BackendError with discriminated code field (network/server/client/timeout) - Embed API: startEmbeddings, streamEmbeddingProgress, cancelEmbeddings - Search with mode param (hybrid|semantic|bm25) and enrichment * refactor(web): rewrite Graph RAG tools for backend-only HTTP queries - Search tool: uses enriched /api/search (1 call replaces 31 sequential queries) - Cypher tool: removes browser-side embedding; {{QUERY_VECTOR}} routes to /api/search with mode:'semantic' instead of local transformers.js - Grep tool: uses /api/grep instead of in-memory fileContents map - Read tool: uses /api/file instead of fileContents map lookup - Impact tool: getCallSiteSnippet now async via /api/file - createGraphRAGTools now accepts GraphRAGBackend interface instead of 7 separate function params + fileContents map - createGraphRAGAgent simplified to (config, backend, context?) - Removed imports: embedder, lbug/schema (replaced with gitnexus-shared) - Net: -205 lines * refactor(web): delete WASM infrastructure, remove 7 packages (-5242 lines) Delete browser-side LadybugDB, embeddings, search, and worker: - gitnexus-web/src/core/lbug/ (adapter, csv-generator, schema, query-result) - gitnexus-web/src/core/embeddings/ (embedder, pipeline, text-gen, types) - gitnexus-web/src/core/search/ (bm25-index, hybrid-search) - gitnexus-web/src/workers/ingestion.worker.ts (828 lines) - gitnexus-web/src/services/server-connection.ts (merged into backend-client) - gitnexus-web/src/types/lbug-wasm.d.ts Remove packages: @ladybugdb/wasm-core, @huggingface/transformers, comlink, minisearch, vite-plugin-wasm, vite-plugin-top-level-await, vite-plugin-static-copy Update vite.config.ts: remove WASM plugins, COOP/COEP headers, worker config, optimizeDeps exclude Update imports: App.tsx, DropZone, Header, AnalyzeProgress, BackendRepoSelector, useBackend → backend-client * refactor(web): replace Worker/Comlink with direct BackendClient calls - useAppState: remove Worker instantiation, Comlink.wrap, apiRef. All queries now go through BackendClient HTTP functions directly. - Agent runs on main thread (I/O-bound LLM streaming, not CPU-bound) - initializeAgent: creates GraphRAGAgent with GraphRAGBackend interface bound to BackendClient methods (runQuery, search, grep, readFile) - startEmbeddings: calls POST /api/embed + SSE progress instead of running browser-side transformers.js pipeline - switchRepo: no longer loads graph into WASM DB or extracts fileContents - App.tsx: handleServerConnect simplified (no fileContents, no loadServerGraph) - Delete old backend.ts (replaced by backend-client.ts) - Net: -396 lines * fix(web): fix await-in-map build error in agent streaming Move dynamic import of AIMessage outside .map() callback to avoid "await can only be used inside an async function" build error. * fix(web): remove stale apiRef references that broke chat functionality sendChatMessage referenced apiRef.current (deleted Worker ref) which would throw TypeError. Replaced with agentRef.current guard since agent now runs on main thread. * fix(server): dispose embedJobManager on shutdown, fix job mutation - Add embedJobManager.dispose() to shutdown handler (was missing, causing cleanup timer to keep Node process alive) - Replace direct job.repoName/status mutation with updateJob() to ensure SSE event emission for initial status change * fix(server): parameterize Cypher, harden grep, unify SSE endpoints - Search enrichment: replace string interpolation with executePrepared() using $nid parameter binding to prevent Cypher injection - Add executePrepared() to core lbug-adapter (prepare/execute pattern) - /api/grep: add 200-char pattern length limit (ReDoS protection), search files on disk instead of loading entire corpus into memory (constant memory usage regardless of repo size) - Extract mountSSEProgress() shared helper for SSE streaming — both analyze and embed endpoints now have consistent heartbeat (30s), event IDs (reconnection support), and X-Accel-Buffering header * refactor(web): remove dead code from Worker-era architecture - Remove loadServerGraph no-op function, interface member, and all consumers - Remove testArrayParams stub and interface member - Remove fileContents state from GraphStateProvider (never populated in server-side architecture) - Remove forceDevice parameter from startEmbeddings (server-side, no device choice) - Replace phantom EmbeddingProgress type with inline { phase, percent } - Replace resolvePathFromContents (needed fileContents Map) with graph-based file path resolution using filePathIndex built from graph nodes - Fix: AI citation grounding ([[file.ts:10]]) now works via graph node lookup instead of broken fileContents-based resolution * fix(web): use streamAgentResponse for full tool_call/reasoning streaming Replace naive agent.stream() loop that only handled content chunks with streamAgentResponse() generator from agent.ts. This properly routes: - reasoning tokens (before/between tool calls) - tool_call events (name, args, status) - tool_result events (completed tool output) - content tokens (final answer after all tools done) Previously the onChunk handler for tool_call/tool_result/reasoning was dead code since the streaming loop only emitted content events. * fix(web): resolve CI type errors from dead code removal - Import GraphNode/GraphRelationship from gitnexus-shared in graph.ts (not re-exported from local types.ts) - Add Route, Tool entries to NODE_COLORS and NODE_SIZES constants - Add PipelineResult type to web types/pipeline.ts - Remove fileContents from CodeReferencesPanel and RightPanel - Remove testArrayParams and forceDevice from EmbeddingStatus - Remove forceDevice args from startEmbeddings() calls in App.tsx - Fix embeddingProgress property accesses for simplified type * fix(ci): add setup-gitnexus-web action, build shared once per job - Remove prepare script from gitnexus-shared (tsc not available during npm ci of consuming packages) - Create .github/actions/setup-gitnexus-web composite action: builds gitnexus-shared then runs npm ci for gitnexus-web - setup-gitnexus action: already builds gitnexus-shared for CLI jobs - ci-quality typecheck-web: uses setup-gitnexus-web (DRY) - ci-e2e: uses setup-gitnexus-web (DRY) - ci-tests: gitnexus-shared already built by setup-gitnexus, just install web deps without rebuilding * fix(ci): use prepare script so gitnexus-shared builds during npm ci Move typescript from devDependencies to dependencies in gitnexus-shared so the prepare script (tsc) works when npm resolves file: deps during npm ci. No GHA modifications needed — npm handles the build lifecycle automatically. Remove manual gitnexus-shared build steps from setup-gitnexus and setup-gitnexus-web actions. * fix(ci): build gitnexus-shared explicitly in setup actions The file: dependency protocol doesn't reliably run prepare scripts because devDependencies aren't installed first. Instead of fragile lifecycle hacks, build gitnexus-shared explicitly in both setup actions: - setup-gitnexus: npm install && npm run build in gitnexus-shared/ - setup-gitnexus-web: same, before npm ci in gitnexus-web/ - ci-tests: shared already built by setup-gitnexus, web just npm ci No prepare script, no dist in git, no typescript as a prod dependency. * fix: remove CALL from CYPHER_WRITE_RE — breaks FTS and vector search CALL is used by read-only procedures: CALL QUERY_FTS_INDEX(...) and CALL QUERY_VECTOR_INDEX(...). Adding it to the write guard blocked all FTS search, causing 3 test failures. The database is opened in read-only mode as defense-in-depth against write procedures via CALL. Keep INSTALL and LOAD in the blocklist (genuinely dangerous). * fix(web): update vercel.json for gitnexus-shared, remove COOP/COEP - Add installCommand that builds gitnexus-shared before installing web deps (Vercel doesn't know about the monorepo file: dependency) - Remove Cross-Origin-Opener-Policy and Cross-Origin-Embedder-Policy headers (no longer needed — WASM LadybugDB removed) * fix(web): update tests for deleted modules - Delete csv-generator.test.ts (tests deleted WASM-only csv-generator) - Update security-guards.test.ts: import NODE_TABLES/REL_TYPES from gitnexus-shared instead of deleted src/core/lbug/schema - Update server-connection.test.ts: import normalizeServerUrl from backend-client, remove extractFileContents tests (function deleted) * fix(e2e): remove Server tab click — UI is now server-only The DropZone no longer has ZIP/GitHub/Server tabs (browser ingestion was removed). The server URL input is directly visible on the landing page. Update e2e test to skip the tab click and go straight to input. All 5 e2e tests pass locally. * refactor: use gitnexus-shared for PipelinePhase/PipelineProgress types CLI was duplicating PipelinePhase and PipelineProgress locally instead of importing from gitnexus-shared. Updated all consumers to import directly. Also removed dead code: SerializablePipelineResult, serializePipelineResult(), deserializePipelineResult(). * fix(server): address PR #536 review — security, race conditions, dead code - Fix path traversal in POST /api/analyze: split into isAbsolute + normalize check - Add shared repo lock (activeRepoPaths) preventing concurrent analyze+embed on same repo - Fix 202 response returning actual job.status instead of hardcoded 'queued' - Add 30-minute timeout for embedding jobs (was missing unlike analyze jobs) - Fix DropZone calling startAnalyze without setting backend URL first - Add SSE reconnect with exponential backoff (3 retries) and Last-Event-ID - Fix normalizeServerUrl to return base URL (no /api suffix) — clear contract - Delete dead code: proxy.ts, server-graph-hydration.ts, pipeline.ts re-export barrel - Update LoadingOverlay to import PipelineProgress directly from gitnexus-shared * fix(server): fix repo lock key mismatch and embed cancel race - Use getStoragePath(targetPath) as lock key in analyze handler to match embed handler's entry.storagePath — keys now always align - Guard embed completion: don't overwrite 'failed' with 'complete' when job was cancelled while pipeline was still running - Remove unused jobType parameter from acquireRepoLock - Log backend.init() errors instead of silently swallowing * fix: add gitnexus-shared as a local dependency in package-lock.json * refactor: move language detection to gitnexus-shared, add syntax highlighting for all 15 languages Move getLanguageFromFilename() from CLI to gitnexus-shared with COBOL support added. Add getSyntaxLanguageFromFilename() for Prism-compatible syntax highlighting covering all 15 code languages plus auxiliary formats (json, yaml, markdown, html, css, bash, sql, xml). Refactor CodeReferencesPanel to use shared function instead of a local 30-line switch. Delete dead gitnexus-web/src/config/supported-languages.ts (web already imports SupportedLanguages from gitnexus-shared). * feat(web): add first-time user onboarding with auto server detection Replace the manual "Connect to Server" panel with an automatic onboarding flow that guides first-time users through starting the GitNexus server. Server detection: - useBackend hook polls via setTimeout chain (3s, no overlap) - Page Visibility API pauses polling when tab is hidden - SSE heartbeat (/api/heartbeat) for instant disconnect detection Onboarding UI (OnboardingGuide.tsx): - Step-by-step flow: copy command → run → auto-connect - Smart command: shows `gitnexus serve` in dev, `npx gitnexus@latest serve` in prod - Node.js version auto-detected from package.json via Vite define - Faux terminal windows with copy-to-clipboard, platform tabs, polling indicator Transitions (DropZone.tsx): - Crossfade wrapper with snapshot pattern for smooth phase transitions - Three phases: onboarding → success (1.2s hold) → loading → graph - Auto-recovery: falls back to onboarding if server dies or connect fails Server changes: - GET /api/heartbeat: SSE endpoint for liveness detection - GET /api/info: version, launch context, Node.js version - npm run serve script for local development - app.disable('x-powered-by') hardening * feat(web): add repo analysis UI, SSE heartbeat, and review fixes Repo analysis: - AnalyzeOnboarding: empty-state card when server has zero repos - RepoAnalyzer: GitHub URL + Local Folder tabs with browse button - Header repo dropdown: click project badge to switch repos or analyze new - DropZone 'analyze' phase integrated into Crossfade transitions Reliability fixes from 5-agent review: - Polling: stop scheduling timers when tab hidden, restart on visibility return - Heartbeat: exponential backoff (1s/2s/4s, 3 retries) prevents graph loss on blip - RepoAnalyzer: completion timer tracked in ref, cleaned up on unmount - DropZone: standardized card padding (p-7), heading sizes (text-lg) Accessibility: - prefers-reduced-motion global CSS rule (WCAG 2.3.3) - focus-visible rings on CopyButton - cursor-pointer on all Header buttons - Consistent rounded-xl on all dropdowns Cleanup: - Deleted dead AnalyzeSheet.tsx (219 LOC) and BackendRepoSelector.tsx (89 LOC) - Fixed AnalyzeProgress lucide import (lucide-react → @/lib/lucide-icons) * fix(server): resolve analyze worker fork crash in dev mode The forked analyze worker was crashing immediately with exit code 1 when running via `npm run serve` (tsx). Two issues: 1. Worker path resolved to `analyze-worker.js` but only `.ts` exists in the source directory — the `.js` file is only in `dist/`. 2. On Windows, bare `--import tsx` in execArgv fails because Node's ESM resolver for --import uses the child's CWD, not the parent's node_modules. Windows also rejects raw paths as `d:` is not a valid URL scheme. Fix: detect dev vs prod via `import.meta.url` extension. In dev mode, resolve `tsx/esm` to an absolute `file://` URL via `pathToFileURL()` anchored to the parent's `createRequire` context. This works on all platforms and doesn't depend on the child's CWD or PATH. Also captures child stderr for better crash diagnostics. Verified: `POST /api/analyze` with GitHub URL completes successfully in dev mode (tsx) — status goes from cloning → analyzing → complete. * fix(server): add worker auto-retry, error handling, and crash diagnostics Worker resilience: - Auto-retry up to 2 times with exponential backoff (1s, 2s) on crash - SSE progress shows "Retrying after crash (1/2)..." during retry - Captures child stderr for crash diagnostics in failure message - AnalyzeJob tracks retryCount per job Server error handling: - app.listen wrapped in Promise so EADDRINUSE/EACCES propagate cleanly - serve.ts catches startup errors with friendly messages and exit code 1 - EADDRINUSE gets actionable guidance (stop other process or --port flag) - Global uncaughtException/unhandledRejection handlers prevent silent exits - DEBUG=1 env var shows full stack traces * feat: add e2e tests for onboarding flows, worker retry, and error handling E2E tests (onboarding.spec.ts — 11 tests): - Flow 1: OnboardingGuide shown when server unreachable (6 tests) - Flow 2: Auto-connect with success card, analyze phase for zero repos - Flow 3: Analyze form — GitHub URL validation, Local Folder tab, tab switching - Flow 4: Repo dropdown in exploring view (skipped without live server) Updated server-connect.spec.ts: - Replaced manual Connect button flow with auto-connect waitForGraphLoaded Server resilience: - Worker auto-retry (2 attempts with exponential backoff) on crash - Friendly error messages for serve startup failures (EADDRINUSE etc.) - Global uncaughtException/unhandledRejection handlers prevent silent exits - app.listen wrapped in Promise for proper error propagation * refactor(shared): enforce exhaustive language coverage via Record types Replace the if/else chain in getLanguageFromFilename with two exhaustive Record<SupportedLanguages, ...> maps: - EXTENSION_MAP: every language → its file extensions - SYNTAX_MAP: every language → its Prism syntax identifier Adding a new member to the SupportedLanguages enum without adding it to both maps now produces a TypeScript compile error: Property '[SupportedLanguages.NewLang]' is missing in type... This matches the existing pattern in languages/index.ts (providers table) which already uses `satisfies Record<SupportedLanguages, LanguageProvider>`. Three compile-time enforcement points now exist: 1. EXTENSION_MAP in language-detection.ts (file extensions) 2. SYNTAX_MAP in language-detection.ts (Prism syntax identifiers) 3. providers in languages/index.ts (LanguageProvider instances) * feat(web): load source code from server and scroll to selected line CodeReferencesPanel now fetches file content via GET /api/file when a node is selected, instead of showing "Code not available in memory". - Fetches via readFile() from backend-client when selectedFilePath changes - Shows loading spinner while fetching - After content loads, auto-scrolls to the selected node's startLine - Highlights the selected line range with a cyan left border - Cancels in-flight fetch if selection changes before it completes Also: refactored language-detection.ts to use exhaustive Record types (EXTENSION_MAP and SYNTAX_MAP) so adding a new SupportedLanguages enum member without implementing extensions/syntax is a compile error. * feat: buffered file reading for Code Inspector Server: GET /api/file now supports ?startLine=N&endLine=M for reading a line range instead of the entire file. Returns { content, startLine, endLine, totalLines }. Client: readFile() returns ReadFileResult with metadata. When selecting a symbol (function, class, method), fetches only ±50 lines around the symbol's startLine/endLine instead of the full file. File nodes still fetch the entire file. SyntaxHighlighter startingLineNumber set from the buffer offset so line numbers are correct even for partial reads. * fix: adapt readFile callers to new ReadFileResult return type tools.ts: readFile comes from GraphRAGBackend interface which returns Promise<string> (the adapter in useAppState extracts .content), so revert the { content } destructuring back to plain string assignment. useAppState.tsx: wrap backendReadFile with { repo } options object and extract .content to satisfy the GraphRAGBackend interface. * fix(web): ensure new repos appear in list immediately after analysis Two fixes: 1. DropZone: handleAnalyzeComplete now passes the repoName through to connectToServer so the specific newly-analyzed repo loads — not the server's default first repo. 2. App.tsx: fetchRepos() is now awaited BEFORE handleServerConnect in both the DropZone and Header flows. This ensures the repo list is populated before the exploring view renders, so the new repo appears in the header dropdown immediately without a page reload. * feat: delete repos, re-analyze with force, select after analysis Server — DELETE /api/repo: - Acquires repo lock first (409 if analyze/embed in flight) - Closes LadybugDB, deletes index + clone dir, unregisters, re-inits - Lock released in finally block Server — analyze complete: - backend.init() must succeed before SSE complete fires - If backend.init() fails, job is marked failed (not complete) Web — Header repo dropdown: - Re-analyze: calls POST /api/analyze with force=true, shows spinning icon + inline progress bar via SSE - Delete: acquires lock, aborts any running re-analysis SSE for same repo, refreshes list, switches to next repo - After analysis completes: refreshes repo list, connects to the specific repo by name, loads graph, shows in explorer - Retry with 1.5s backoff on 404 (server may still be reinitializing) Type safety: - err: any → err: unknown + instanceof BackendError in retry loop - Added missing BackendRepo + BackendError imports in App.tsx	2026-03-28 14:07:11 +00:00
