Fwd: claude.ai code review of pharo-v

by Aaron Wohl

I regularly have Claude.AI review my code https://awohl.com, I pointed Claude at the Pharo-VM to see what it could see. A lot of the issues it found are things like strcpy without bounds checks with strings no one would ever make that big. However, it found some issues that are always triggered. Full list of issues https://github.com/avwohl/iospharo/blob/main/docs/pharo-vm-code-reivew-2026… I did not make an AI-generated patch list. stephane.ducasse(a)free.fr mentioned copyright concerns by guillermo.polito(a)inria.fr of accepting AI code. I assume this is due to the inability to copyright AI-generated work and to AI's tendency to steal others' work and lie about its origins. However, a lot of the fixes are so trivial, like off-by-one errors, that I don't know how much of an issue it is. If you want me to PR fixes and or tests that trigger for the full list, or always list, let me know. Many of the issues would only happen if someone were trying to break things (MAXLEN symlinks, damaged image files). If one were a mindset, it could be called AI slop. However, here is a short list of things that always cause issues in everyday operation: for example, every plugin loaded damages heap memory, or the nightly build of signed code disables SSL checks, so a simple DNS hack could get malicious code signed. Source: ~/pharo.md (review of /Users/wohl/esrc/pharo-vm @ pharo-10, 2026-05-11) Filter: only items that fire in normal benign operation, not edge cases requiring huge/crafted strings or attacker-chosen sizes. ================================================================ A. ALWAYS â MEMORY DAMAGE / UNDEFINED BEHAVIOR ================================================================ 1. sqNamedPrims.c:56-57 â calloc(sizeof(ModuleEntry)+strlen(name)) then strcpy writes strlen+1; 1-byte heap overflow on every plugin load. [#3.26] 2. ffi/callbacks/callbacks.c:14-32 â stack-allocated CallbackInvocation registered in runner->callbackStack/global queue; sig_longjmp exit leaves dangling stack pointer after every same-thread callback. [#2.8] 3. ffi/typesPrimitives.c:174-188 â setHandler(receiver, structType) stores pointer before failed()/ffi_get_struct_offsets checks; any error path frees memory while receiver still holds the dangling handle. [#2.6] 4. threadSafeQueue.c:113-137 â queue->first and node->element read outside the mutex; lock-holder's free(node) leaves the other consumer walking freed memory on every concurrent dequeue (hit by every FFI workload). [#3.21] 5. SocketPluginImpl.c:1109-1123 â sqSocketDestroy frees PSP(s) after sqSocketAbortConnection queues a closeHandler against pss; AIO dispatch fires on freed memory. [#3.22] 6. ffi/utils.c:43-50 â readString returns an un-pinned image-memory pointer; GC between strlen() and the caller's strcpy invalidates the length and the address. [#5.27] 7. ffi/callbacks/callbacks.c:24-29 â runner->callbackStack chain updated without any lock; reentrant callbacks from multiple threads on the same Runner corrupt the linked list. [#5.4] 8. pathUtilities.c:233-237 â strrchr(name,'.') result stored in fileExtension, but the NULL guard tests the unrelated `extension` variable; strcmp(NULL,...) crashes on any directory entry without a dot (e.g. "Makefile"). [#4.2] 9. pathUtilities.c:163 â first[strlen(first)-1] reads first[-1] (one byte before the buffer) whenever first is "", reachable from parameters.c:210-212 fallback. [#4.3] 10. externalPrimitives.c:57,66 â module path assembled in a file-static moduleNameBuffer with no lock; concurrent loads scribble each other's path and dlopen/LoadLibrary sees a torn string. [#5.3] 11. debugUnix.c:88-95,122-162 â SIGSEGV/SIGBUS/SIGFPE handler calls fopen/vfprintf/backtrace_symbols_fd/ctime_r/semaphore_wait (none async-signal-safe) and uses SA_NODEFER so the handler can re-enter itself on every crash. [#5.1] 12. debugUnix.c:123,144,154 â sigaction.sa_mask never initialized via sigemptyset for term_handler_action and sigpipe_handler_action; kernel reads uninitialized stack to decide what to mask on every install. [#5.2] 13. debug.c:57-66 â glibc strerror_r returns a pointer that may not write to the supplied buffer; caller prints the buffer unconditionally, leaking uninitialized stack bytes on every error path. [#5.7] 14. SocketPluginImpl.c:2494-2496 â sqSocket lastError stored in a file-static, clobbered across sockets; every concurrent socket failure overwrites another socket's error state. [#5.17] 15. aioWin.c:457/465 â heap-interior alias into allHandles transiently equals a freshly malloc'd region; any early return between the two assignments leaves a free-of-interior or double-use hazard. [#1/Â§9 PARTIAL] ================================================================ B. ALWAYS â SECURITY / CORRECTNESS (NOT MEMORY DAMAGE) ================================================================ TLS / SqueakSSL --------------- 1. sqUnixSSL.c:89-143 â SSL_CTX_set_verify never called; SSL_get_verify_result returns X509_V_OK by default â no certificate validation on any TLS connection. [#2.9] 2. sqUnixSSL.c:102-107 â SSLv23_method with only SSLv2/v3 disabled; TLS 1.0 and 1.1 still accepted on every handshake. [#2.9 / #6.3] 3. sqUnixSSL.c:115 â cipher list "!ADH:HIGH:MEDIUM:@STRENGTH" permits MEDIUM ciphers. [#2.9] 4. sqUnixSSL.c:107 â no SSL_OP_NO_COMPRESSION (CRIME), no SSL_OP_NO_RENEGOTIATION, no SSL_OP_CIPHER_SERVER_PREFERENCE. [#6.3] 5. sqWin32SSL.c:269-275,215,349-353 â sqExtractPeerName copies serverName verbatim into peerName instead of extracting the cert subject; epp.pwszServerName=NULL disables SChannel's hostname check, so image-side peerName==serverName is meaningless on every connection. [#3.19] 6. sqMacSSL.c:154-201,262-272,363-383 â kSSLSessionOptionBreakOnServerAuth disables auto verification; manual SecTrustEvaluate runs with no SSL policy carrying the hostname, so hostname is never checked. [#3.20] 7. sqWin32SSL.c:216-218 â SP_PROT_TLS1_0/1_1/1_2 enabled for both client and server roles. [#6.1] 8. sqMacSSL.c:154-164 â SSLSetProtocolVersionMin(ctx, kTLSProtocol1) sets minimum to TLS 1.0. [#6.2] VM internals ------------ 9. memoryUnix.c:66-89,109-111 â JIT pages mmap'd PROT_READ|PROT_WRITE|PROT_EXEC permanently; sqMakeMemoryExecutableFromTo / NotExecutable hooks are commented out, so W^X is defeated on Linux/FreeBSD. [#5.24] 10. debug.c:45 â error(char*) forwards the argument as the format string into the vfprintf-style logger; exported API contract leaks a %n/%s primitive to any future caller-controlled string. [#4.10] 11. ffi/typesPrimitives.c:170-172 â getHandler() returns the first slot of any oop with no class tag check; libffi consumes attacker-shaped ffi_type fields on every struct cif build, giving a controlled-dispatch primitive to anyone who can register an FFI struct. [#2.5] Build / supply chain (every build / every CI run) ------------------------------------------------- 12. Jenkinsfile:84,249 â fetch-and-execute installer via `wget â¦ | bash` over plain HTTP. [#7] 13. scripts/runTests.sh:31 â `wget -O - https://get.pharo.org/64/80 | bash`, executed from PR workflows.

Re: "Claude, My New Pair Programming Partner" â New blog post on all: objects all: theTime

Hello Koen and everyone. Itâs really nice to see people getting more and more interested in AI, especially for Pharo. But I think you are wrong about ChatPharo. I understand very clearly your point that the AI for and in Pharo is in his realy stagses. But Iâm working very hard to make it more usable for more and more people ( people are also scared of using AI in Pharo because they had bad experiences with ChatGPT when it was launched in 2022). It wasnât created to do code generation tasks. That said. I wanted to clarify some points about ChatPharo: - ChatPharo is not a toy. It has a big engineering part inside of it (Multiple people, including PhDs, and engineers, contribute to it). Indeed, Iâm not doing a lot of publicity because i also doing my PhD at the same time. - From an AI engineer's POV, the dependencies on the company that provides models accessible from the web are not very convenient. I agreed that Claude is the best model for code generation (and it appears everything else but you are limited to the company API and the backend. FYI: the newest Claude and OpenAI models have more than 1T parameters.) But let me ask you a question, what if tmrw claude changes its policies now after their deal with SpaceX? (They will expect more and more people that subscirbe to their 20 euros, right? ) Well, in that case, any CEO in his right mind will increase the price ( it will be one million cause of that, of course, why do they do that, whatever they tell, the people will buy it because now they canât live without it). Thatâs why itâs not very convenient ( this is what i think). - Ollama ( that were considered one of the best companies that provided the models for free (local and on the cloud). Now you should pay for the model inference on the cloud ( it was free ), because they saw that more people are getting interested in the model that runs on the cloud ( and itâs free), they now prohibit you from using it unless you pay 20 euros. - Why do you think that the model that appears now is getting better? Itâs not training or something else. There's nothing left in the whole internet to train on anyway. They now want real data ( you might see in most of the newest technical papers the sentence high quality token. You might ask yourself a question about where this data appears if there is nothing left on the internet to train? Now, make no mistakes, Iâm not telling you NOT to use AI for Pharo. I and (we) are and (wonât) be able to concure with the companies that have models that have > 1T of parameters. (We don't have the budget, nor the resources for that). Iâm just trying to justify that chatpharo for now is not (and wonât) be capable of competing with the models from the biggest company. Ofc everyone is free. But I wanted to just shed light on a few points that more and more people ask questions about.

"Example of Describing Spec Application Behaviour with Hera" â New blog post on all: objects all: theTime

by Koen De Hondt

Dear Pharo users and developers, I posted the fourth and final article in the series about describing Spec application behaviour with Hera. The first post explained how Hera manages open Spec windows. The second post explained how Hera identifies presenters so they can be referenced in Gherkin scenarios. The third post explained how Hera expresses steps to interact with Spec presenters. This final post includes an example that ties everything together. https://all-objects-all-the-time.st/#/blog/posts/23 As always, all feedback is welcome. Happy reading! Ciao, Koen

Intelligent Code Assistant for Pharo

by omar abedelkader

Hello, Iâm currently experimenting with a new approach to code completion in Pharo. Unlike the existing token-based completion (which suggests one token at a time), this approach uses an LLM to generate larger, meaningful code segmentsâalso known as Fill-in-the-Middle (FIM) code completion. This message is simply to gauge interest in this topic. Once the system is ready, we will reach out to interested users. There is nothing specific expected from youâjust using the plugin as you normally code. The plugin will handle the evaluation process and, with your consent, send us a report summarizing usage. This report will only include aggregated metrics (such as acceptance and rejection rates). We will not collect any information about your code (e.g., class names, method names, or content). The plugin itself is lightweight and runs entirely on your machine. The LLM is also designed to run locally, with our largest model requiring approximately 5 GB of RAM. If you are interested in this new approach to code completion, feel free to reply to this email. Best regards, Omar AbedelKader
