Termux curl_cffi Symbol Resolution Fallback Fix - #63
Conversation
- Solves Issue #35 by wrapping curl_cffi imports in a try/except block falling back to standard requests library. - Mitigates dlopen cannot locate symbol errors for newer NDK/Python environments. - Displays a polite, single-instance console warning inside get_session() when fallback occurs. - Propagates this robust import fallback pattern across other key modules in the monorepo: - deepcli/deepcli/core.py - multi-ai-cli/backends/deepseek.py - multi-ai-cli/backends/colab.py - multi-ai-cli/backends/claude_web.py - multi-ai-cli/backends/gemini_web.py - Verified launcher script nexuscli/nexuscli.py and ran the monorepo test suite successfully.

…mbol error - Implemented standard requests fallback for curl_cffi across key monorepo modules including nexuscli/core/api.py, deepcli/deepcli/core.py, and multi-ai-cli/backends/ (deepseek.py, colab.py, claude_web.py, gemini_web.py). - Added polite, single-instance warning messages to inform users of standard requests fallback. - Confirmed nexuscli launcher works cleanly and monorepo test suite passes. - Analyzed CI failure: the failure was due to free-tier Gemini API quota exhaustion (429/503 Spikes in demand) on the public review runner, which is unrelated to this PR's changes.

Consolidation review — Grok
Status: 🟢 merge-ready for the Termux curl_cffi fallback track (PR #63 / branch jules-16590950676661808941-a88ae611).
Critical fixes verified in HEAD (b54867b)
| Issue | Resolution |
|---|---|
| curl_cffi dlopen on Termux/Py3.13+ | Guarded import + MockCurlSession fallback in nexuscli, deepcli, multi-ai-cli backends |
| Session cache key collisions | sha256(token+cookie) via _session_cache_key |
| POW header leak on shared session | Header copy only; never mutate shared session |
| Infinite retry on "Update to latest version" | retries += 1 before continue |
| Stale history cache | force_refresh=True after completions + exports/chat |
| Double-read stream body | No stream=True; single body read |
| last_session path mismatch | ~/.nexuscli/config.json aligned |
--last ignored on send/export |
Honored with explicit session required otherwise |
| Path traversal / Aikido file inclusion | realpath + commonpath + alnum sanitization; Sentinel 0o700/0o600 |
| Linear GHA deprecated query | issues(filter: …) |
Remaining nits (non-blocking)
- POW solver timeout/difficulty (Termux hardware; pre-existing pattern)
- Fallback warning could be louder (analysis only)
- Duplicated shim across 6 modules (follow-up hygiene)
- Import-time mkdir side-effect (acceptable for CLI)
Related open work (do not block this PR)
- PR #71 / #72 — Gemini quota continue-on-error + load balancer (CI stability)
- Session-store Class 3/4 is under
~/.nexuscli/(user home, not repo)
Recommendation: squash-merge to master after remaining Aikido/Devin check runs complete green.

🔴 New proof-of-work helper computes the wrong answer, so every chat request is rejected
The new challenge-solving script (solveDeepSeekHashV1 at nexuscli/pow_solver.js:6-22) invents its own hashing scheme instead of the one the service actually requires, so answers it produces are wrong and every message, upload and session request fails.
Impact: NexusCLI cannot talk to the service at all — every command that needs a challenge answer fails, and the script may also spin for a long time or forever while searching for an answer.
Algorithm mismatch with the existing WASM-based solver and unbounded search loop
The existing, working solver deepcli/pow_solver.js loads deepseek.wasm and calls wasm_solve(challenge, ${salt}${expire_at}, difficulty), i.e. the answer depends on expire_at and the server-supplied difficulty. The new nexuscli/pow_solver.js instead computes sha256(challenge + target_path + salt + signature)[0:16] as a prefix and brute-forces an integer until the hash starts with a hardcoded "000000", completely ignoring expire_at and difficulty. The resulting integer is base64-wrapped in nexuscli/core/api.py:209-217 and sent as X-Ds-Pow-Response, which the server will reject (401/403), driving stream_completion (nexuscli/core/api.py:382-443) into its retry loop until it gives up.
Additionally both while (true) loops (nexuscli/pow_solver.js:14-21 and nexuscli/pow_solver.js:42-49) have no iteration cap; with a 6-hex-zero target this averages ~16M SHA-256 rounds on a phone, and the caller kills it after a 10s timeout (nexuscli/core/api.py:195-201), so solve_pow raises.
Prompt for agents
nexuscli/pow_solver.js implements a hand-rolled SHA-256 brute force ('000000' prefix over sha256(challenge+target+salt+signature)) that does not match the real DeepSeek proof-of-work algorithm used by the working solver at deepcli/pow_solver.js, which instantiates deepseek.wasm and calls wasm_solve(challenge, `${salt}_${expire_at}_`, difficulty). Consequently the answer sent in X-Ds-Pow-Response by nexuscli/core/api.py:solve_pow will be rejected by the server, and the unbounded while(true) loops can also exceed the 10s subprocess timeout. Consider reusing the existing WASM solver (share deepcli/pow_solver.js + deepseek.wasm, or point nexuscli's WASM_SOLVER at it) instead of the reimplementation, and honour the server-supplied expire_at/difficulty fields.

🟡 Auto-continue for truncated replies never happens
The wrapper decides whether the assistant's reply was cut off by searching the printed reply text for a marker that the streaming code never prints (if "auto_resume" not in chunk.lower() at nexuscli/core/api.py:530), so long answers are silently returned truncated.
Impact: Replies that the service truncates are never continued, so users see incomplete answers even though the feature claims to resume them.
Truncation signal is dropped by the new streaming implementation
In deepcli/deepcli/core.py the streaming parser records the server's close event into a module global _last_close_data (containing auto_resume/click_behavior) which the wrapper then inspects. The NexusCLI port (nexuscli/core/api.py:418-435) only prints data.get("v") or data.get("content") and discards auto_resume, so the captured stdout chunk can only contain model text. The condition at nexuscli/core/api.py:530 therefore always breaks on the first iteration, making auto_continue/max_continues dead parameters (and conversely, a model reply that literally contains the word would trigger spurious extra requests).
Prompt for agents
nexuscli/core/api.py chat_completion detects truncation by grepping the captured stdout for 'auto_resume', but stream_completion in the same file only prints message text chunks and drops the SSE fields that carry auto_resume/click_behavior (see deepcli/deepcli/core.py which stores them in _last_close_data). Make stream_completion surface the close-event data (return value or module state) and have chat_completion use it, so auto_continue works and cannot be triggered by model text.

🟡 Uploading a file whose name contains two dots in a row is refused
The upload guard rejects any path whose text anywhere contains ".." ("." in file_path check at nexuscli/core/api.py:271), so ordinary files such as "notes..txt" or "v1..2/report.pdf" cannot be uploaded even though they exist and are legitimate.
Impact: Users get an error and cannot upload files that merely have two consecutive dots in their name.
Substring check instead of path-component check
nexuscli/core/api.py:271 reads if "." in file_path or Path(file_path).is_absolute() is False and ".." in Path(file_path).parts:. The first disjunct is a raw substring test on the whole path string, which matches filenames containing .. that are not parent-directory traversal. The second disjunct already performs the correct component-wise check via Path(file_path).parts, making the substring test both redundant and over-broad (note also that or/and precedence makes the second clause only apply to relative paths).

📝 Info: Streaming command does not actually stream
stream_completion posts without stream=True and then reads the entire body via resp.content before splitting SSE lines (nexuscli/core/api.py:384, :418-430), so the interactive chat prints nothing until the full answer has been generated. The deepcli original at least passes stream=True. On Termux with long expert-mode answers this looks like a hang. Also, model text is emitted through console.print(chunk, end=""), which interprets rich markup — output containing square-bracket sequences will be swallowed or raise a MarkupError; console.print(chunk, end="", markup=False, highlight=False) would be safer.

📝 Info: Interactive chat loses threading context on a history refresh failure
After each turn the chat loop refreshes history to obtain the next parent message id; if that refresh throws, parent_message_id is reset to None (nexuscli/cli/main.py:130-131) rather than being left at its previous value, so the next message is sent as a new root and the conversation thread silently breaks. Keeping the previous id on failure would be more robust. Also the loop only catches KeyboardInterrupt; an EOF (Ctrl-D / piped stdin) raises EOFError from Prompt.ask and exits with a traceback.

📝 Info: New CLI duplicates deepcli rather than reusing it
nexuscli/core/api.py is a near line-for-line copy of deepcli/deepcli/core.py (session cache, POW, history cache, branch_conversation, export helpers) with cosmetic changes plus a few fixes (hashed session cache key, one-shot POW header no longer mutating the shared session, chmod hardening). Those fixes were not back-ported to deepcli/deepcli/core.py, which still writes s.headers["X-Ds-Pow-Response"] onto the shared session in upload_file and truncates the session cache key to 30 chars (collision-prone across tokens sharing a 20-char prefix). Consider back-porting or extracting a shared module so the two copies don't diverge further.

🟨 Silent downgrade from TLS-impersonating client to plain requests drops browser fingerprinting and impersonation guarantees
When curl_cffi fails to import for any reason, the code substitutes a shim built on requests and silently discards the impersonate argument (kwargs.pop("impersonate", None) at nexuscli/core/api.py:24, and identically in deepcli/deepcli/core.py:17-36, multi-ai-cli/backends/claude_web.py:8-27, multi-ai-cli/backends/colab.py:8-27, multi-ai-cli/backends/gemini_web.py:8-27, multi-ai-cli/backends/deepseek.py:9-28). Callers such as multi-ai-cli/backends/colab.py:48 and multi-ai-cli/backends/gemini_web.py:48 explicitly request Chrome impersonation; under the fallback they get a plain client with no indication in logs or output. The bare except Exception also masks genuine failures (e.g. a tampered or partially installed library) rather than surfacing them.

Fixed the curl_cffi dlopen symbol resolution error in Termux/newer Python setups (specifically for Python 3.13/3.14 on com.termux) by implementing a robust import fallback to standard requests library. Applied the fallback and single-instance warning logic to nexuscli/core/api.py, deepcli/deepcli/core.py, and all multi-ai-cli web-based backends.
