In `@clib-masterllvm-15/src/clib-uninstall.c`:
- Around line 211-227: The code currently hardcodes "master" when calling
clib_uninstall; replace that with a version parsed from the slug using
parse_repo_version(program.argv[i], "master"), store it in a variable (e.g.,
char *version), pass version to clib_uninstall(owner, name, version), and ensure
version is free() after use and on error paths (similar to owner/name) so the
fallback "master" applies when no `@version` is present and no memory is leaked.

8-10: Use a separate macro name for the include guard.The include guard uses
CLIB_VERSIONas both the guard macro and the version string macro. This violates standard C/C++ header practices and creates potential issues:
- If
CLIB_VERSIONis defined elsewhere before including this header, the version string won't be set.- The dual-purpose usage is confusing for maintainers expecting conventional include guard patterns.
- Standard practice uses a distinct guard macro (e.g.,
CLIB_VERSION_HorCLIB_VERSION_H_).🔧 Proposed fix using a proper include guard
-#ifndef CLIB_VERSION +#ifndef CLIB_VERSION_H +#define CLIB_VERSION_H + `#define` CLIB_VERSION "2.8.0" + `#endif`clib-masterllvm-15/src/clib-uninstall.c-171-181 (1)
171-181:system()calls pose command injection risk (CWE-78).The static analysis correctly flags the
system()calls. Whilesystem()is commonly used in build tools, be aware that:
- Line 172: The
cmdstring is constructed fromfile, which derives from user-suppliedname/version.- Line 181: The
targetstring includes theuninstallcommand from a remotely-fetched JSON manifest. A malicious package could execute arbitrary commands.This is an inherent trust model issue in package managers (similar to npm scripts). Consider:
- Validating/sanitizing the
nameandversioninputs before shell interpolation- Documenting the security implications for users
🛡️ Suggested input validation
Add a validation helper to reject shell metacharacters in package names/versions:
static int is_safe_shell_arg(const char *arg) { if (!arg) return 0; for (const char *p = arg; *p; p++) { if (!isalnum(*p) && *p != '-' && *p != '_' && *p != '.') { return 0; } } return 1; }clib-masterllvm-15/src/clib-uninstall.c-58-73 (1)
58-73: Hardcoded/tmppath is not portable to Windows.The
/tmppaths inget_tmp_tarballandget_untar_commandwill not work on Windows systems. Consider using a platform-specific temporary directory or a portable abstraction.Additionally, the
fileparameter inget_untar_commandis interpolated directly into a shell command. Ifnameorversion(which derivefile) contain shell metacharacters, this could lead to command injection.🛡️ Suggested approach for portability
Consider using environment variables or platform detection:
static const char *get_tmp_dir(void) { `#if` defined(_WIN32) || defined(WIN32) || defined(__MINGW32__) || defined(__MINGW64__) const char *tmp = getenv("TEMP"); if (!tmp) tmp = getenv("TMP"); return tmp ? tmp : "C:\\Temp"; `#else` return "/tmp"; `#endif` }clib-masterllvm-15/src/common/clib-validate.c-64-94 (1)

107-148: Harden slug/tag expansion and ensure cleanup on failure.
clib_release_get_latest_tag()can return NULL, andasprintf()returns -1 on failure. The current code does not check these return values, allowing invalid pointers and failed allocations to proceed. Additionally, whenNULL == pkgtriggers the earlyreturn -1, the allocatedextended_slugbuffer is not freed, causing a memory leak.The suggested fix properly addresses these issues by:
- Adding NULL checks for
clib_release_get_latest_tag()- Adding return value checks for
asprintf()calls- Using a cleanup label with appropriate
free()calls before returns- Ensuring
extended_slugis freed in all error pathsAlso applies to: 172-175

225-227: Fail fast ifcurl_global_initfails to prevent undefined behavior in subsequent curl operations.The
curl_global_cleanup()call at line 267 should only execute if initialization succeeds. Continuing past a failed initialization will attempt curl operations in an uninitialized state.🛠️ Suggested fix

63-80: Usesnprintfwith bounds checking and validateBASE_DIRbefore constructing paths.
BASE_DIRis derived fromgetenv()(lines 26–30), which returns NULL if HOME or AppData is not set. Passing NULL tosprintfat lines 64, 78–80 causes undefined behavior. Additionally, fixed-size buffers (BUFSIZ) can overflow if environment paths are long. Replace allsprintfcalls withsnprintfthat checks the return value and explicitly validate BASE_DIR before use.Also note: helper functions
json_cache_path(line 45) andpackage_cache_path(line 50–51) have identical unsafesprintfcalls and should be similarly hardened.🛠️ Suggested fix

184-190: Add validation forpathconf()results before using for VLA sizes.
pathconf()returns -1 on error; using it directly as a VLA size invokes undefined behavior. Add fallback checks in both locations wherepath_maxis assigned frompathconf():

330-332: Fail fast ifcurl_global_initfails.Continuing after libcurl initialization failure can cause undefined behavior during subsequent fetch/install operations. However, the suggested fix is incomplete—it skips
curl_global_cleanup()andclib_package_cleanup(). A proper fix should ensure all cleanup code executes, either by adding the cleanup calls before returning or by using agoto cleanuppattern similar to other functions in this file:🛠️ Suggested fix

813-864: Use curl's authentication mechanisms instead of embedding tokens in URLs.The current implementation embeds the auth token directly in the URL string passed to curl (e.g.,
https://<token>@raw.githubusercontent.com/...). This exposes the token to leakage via curl verbose logging, process memory inspection, and system caches. UseCURLOPT_USERPWDorCURLOPT_HTTPAUTHwith an Authorization header instead, or configure curl to extract credentials from other sources (e.g.,.netrc).clib-masterllvm-15/src/common/clib-package.c-1210-1225 (1)
1210-1225: SetCFLAGSto the composed value, not the original environment variable, and free the allocated memory.Line 1224 passes
cflags(the original environment variable) tosetenv()instead of the newly constructedflagsvariable. This meanspkg->flagsare completely ignored. Additionally,flagsis allocated viaasprintf()but never freed, causing a memory leak.🛠️ Proposed fix
if (cflags) { asprintf(&flags, "%s %s", cflags, pkg->flags); } else { asprintf(&flags, "%s", pkg->flags); } - setenv("CFLAGS", cflags, 1); + if (flags) { + setenv("CFLAGS", flags, 1); + free(flags); + }clib-masterllvm-15/src/common/clib-package.c-631-672 (1)
631-672: Guard against NULL http_get responses.
resis dereferenced on lines 668-669 before the NULL check on line 670. Ifhttp_get_shared()orhttp_get()returns NULL (due to malloc failure), this causes a segmentation fault. This is especially problematic given the retry logic in the code, which suggests network/allocation failures are anticipated.🛠️ Proposed fix
`#ifdef` HAVE_PTHREADS init_curl_share(); _debug("GET %s", json_url); // clean up when retrying http_get_free(res); res = http_get_shared(json_url, clib_package_curl_share); `#else` res = http_get(json_url); `#endif` - json = res->data; - _debug("status: %d", res->status); - if (!res || !res->ok) { + if (!res || !res->ok) { goto download; } + json = res->data; + _debug("status: %d", res->status);clib-masterllvm-15/src/common/clib-package.c-1070-1085 (1)
1070-1085: Handlepathconf()returning -1 and checkrealpath()errors.
pathconf()can return -1 when the limit is not supported, causing a VLA with negative size (undefined behavior). Additionally,realpath()can fail and return NULL, leaving the buffer uninitialized before it's used insetenv()andmkdirp().The fix should clamp

66-72: Fix input buffer bounds and EOF handling.The loop condition
(walk - s) != bufferperforms invalid pointer arithmetic—subtractingsize_tfrom a pointer pointer doesn't check bounds correctly. Additionally,fgetcEOF (typically -1) isn't explicitly handled; the current checksc != 0but should checkc != EOF. The buffer also isn't null-terminated after input.Proposed fix
static void getinput(char *buffer, size_t s) { - char *walk = buffer; - int c = 0; - while ((walk - s) != buffer && (c = fgetc(stdin)) && c != '\n' && c != 0) { - *(walk++) = c; - } + size_t i = 0; + int c = 0; + while (i + 1 < s && (c = fgetc(stdin)) != EOF && c != '\n') { + buffer[i++] = (char)c; + } + buffer[i] = '\0'; }clib-masterllvm-15/src/common/clib-package.c-420-434 (1)
420-434: Eliminate double-checked locking race condition ininit_curl_share().

1001-1008: Handlemallocfailure and protectrefsmutation from race condition.The
malloccall at line 1003 can fail and return NULL, but the code immediately dereferencesstatuswith*status = rcwithout checking, causing a crash. Additionally,pkg->refsis modified without synchronization: it's incremented in the main thread (line ~1045) and decremented in the worker thread (line 1008), creating a data race. The mutexlockalready exists in the codebase and should be used to protect this critical section.🛠️ Proposed fix

1327-1592: Fix sizeof allocation and join outstanding threads on cleanup.Two issues need addressing:
Incorrect allocation size:
fetchsis a pointer-to-pointer array (fetch_package_file_thread_data_t **), but it's allocated withsizeof(fetch_package_file_thread_data_t)per slot instead ofsizeof(*fetchs). This allocates struct-sized memory rather than pointer-sized memory.Missing thread cleanup on error: When errors occur in the download loop (e.g., line 1488), control flows to cleanup via
goto cleanup. However, background threads stored in thefetchsarray continue running while the cleanup code merely frees the array without joining the threads. This can cause resource leaks or crashes.The proposed fix correctly addresses both issues by using
sizeof(*fetchs)for allocation and iterating through the fetchs array to join all running threads before freeing memory.🛠️ Proposed fix
- fetchs = malloc(pkg->src->len * sizeof(fetch_package_file_thread_data_t)); + fetchs = malloc(pkg->src->len * sizeof(*fetchs)); @@ cleanup: @@ `#ifdef` HAVE_PTHREADS - if (NULL != pkg && NULL != pkg->src) { - if (pkg->src->len > 0) { - if (fetchs) { - free(fetchs); - } - } - } - fetchs = NULL; + if (fetchs && pkg && pkg->src && pkg->src->len > 0) { + for (size_t j = 0; j < pkg->src->len; j++) { + if (fetchs[j]) { + int *status = NULL; + pthread_join(fetchs[j]->thread, (void **)&status); + free(status); + free(fetchs[j]); + } + } + free(fetchs); + } + fetchs = NULL; `#endif`clib-masterllvm-15/src/common/clib-package.c-493-516 (1)
493-516: Avoid leakingpkg->flagson eachasprintfcall.
In the array-parsing loop, whenpkg->flagsis initially NULL, it's set to the literal string"", thenasprintfallocates new memory and overwrites the pointer. On subsequent iterations,asprintfallocates additional memory without freeing the previous allocation, causing a memory leak. Additionally, assigning a literal string pointer could cause issues if the asprintf implementation attempts to free it.🛠️ Proposed fix

Extract and use version from the package slug instead of hardcoding "master".
Line 221 hardcodes "master" as the version, but parse_repo_version (from the already-included parse-repo.h) can extract the @version part from the slug. This prevents users from uninstalling specific versions and fails for repositories that use branches other than master.
The fix should call parse_repo_version(program.argv[i], "master") to extract the version, falling back to "master" if no version is specified:

currently hardcodes "master" when calling clib_uninstall; replace that with a
version parsed from the slug using parse_repo_version(program.argv[i],
"master"), store it in a variable (e.g., char *version), pass version to
clib_uninstall(owner, name, version), and ensure version is free() after use and
on error paths (similar to owner/name) so the fallback "master" applies when no
`@version` is present and no memory is leaked.

In `@clib-masterllvm-15/src/clib-build.c`:
- Around line 404-408: clib_package_new_from_slug can return NULL so avoid
dereferencing dependency->name unconditionally: after calling
clib_package_new_from_slug(slug, 0) in the block using dependency, check if
dependency is NULL and handle the error (e.g., log and skip/return) before
calling path_join with dependency->name; only call path_join and
clib_package_free if dependency is non-NULL, and ensure slug is freed in all
paths to avoid leaks.
- Around line 253-256: The inner declaration "char *clean = 0;" is shadowing the
outer variable clean so asprintf assigns into a temporary that is immediately
lost; remove the inner declaration and call asprintf(&clean, "make -C %s -f %s
%s", dir, makefile, opts.clean) so the outer clean variable receives the string
(or alternatively rename the inner variable to a different name and use that
consistently), then ensure the rest of the function uses and frees the outer
clean appropriately where the clean command is executed.
- Around line 333-339: clib_package_new_from_slug can return NULL, so avoid
dereferencing or freeing a NULL dependency: wrap the dep_dir assignment and the
clib_package_free call in a single NULL check around the dependency returned by
clib_package_new_from_slug (use dependency != NULL), e.g. check dependency
before accessing dependency->name and only call clib_package_free(dependency)
when dependency is non-NULL; keep free(slug) outside this guard.
In `@clib-masterllvm-15/src/clib-configure.c`:
- Around line 280-282: Validate and clamp opts.concurrency immediately after
parsing from atol(self->arg) to avoid negative-to-unsigned wrapping and
zero-length VLAs: in the parsing site and in setopt_concurrency ensure the
parsed long is checked and converted to an unsigned int within a safe range
(e.g. min 1 and a defined MAX_CONCURRENCY), and handle out-of-range values by
setting opts.concurrency to the clamp boundary or returning an error; update all
locations that allocate VLAs (the clib_package_thread_t wraps and pthread_t
threads declarations and the other similar arrays) to rely on the clamped
opts.concurrency so you cannot create zero-length or excessively large VLAs.
- Around line 288-304: The code dereferences dependency without checking
clib_package_new_from_slug and uses dep_dir from path_join without verifying
success, and ignores pthread_create errors; update both dependency loops (the
one creating slug and the development-dependencies loop) to: after calling
clib_package_new_from_slug(slug, 0) validate the returned clib_package_t* is
non-NULL before accessing dependency->name or calling clib_package_free; after
calling path_join(opts.dir, dependency->name) check dep_dir != NULL and handle
the error (free dependency/slug and continue/return as appropriate); in the
HAVE_PTHREADS branch check the return value of pthread_create when starting
configure_package_with_manifest_name_thread using wrap (wraps[i]) and
threads[i], and handle failures (do not assume thread started and free
resources) to avoid NULL dereferences and resource leaks.
In `@clib-masterllvm-15/src/clib-init.c`:
- Around line 66-72: In getinput, the bounds check is wrong because it subtracts
the size s from pointer walk; change the loop to track bytes written via (walk -
buffer) and ensure that (size_t)(walk - buffer) < (s ? s - 1 : 0) so you leave
room for the null terminator and handle s == 0, use c = fgetc(stdin) compared
against EOF (not 0), append (char)c while c != EOF && c != '\n' and the
byte-count limit isn't reached, then null-terminate the buffer via *walk = '\0';
ensure all references are to getinput, buffer, s, walk and c.
In `@clib-masterllvm-15/src/clib-uninstall.c`:
- Around line 168-182: The code currently calls system() on the tar command
returned by get_untar_command (cmd) and on the uninstall command returned by
get_uninstall_target (target); replace these system() calls with execv() or
posix_spawn() to avoid shell interpretation: for the untar operation, build an
argv array like ["tar","-xf", file, NULL] and spawn/exec it instead of passing
cmd to system(); for the uninstall action, do not pass the raw target string to
system()—either split/parses the manifest's uninstall field into argv elements
and use execv/posix_spawn, or validate it against an allow-list of safe commands
and construct an explicit argv array before spawning. Ensure you handle
fork/posix_spawn return codes and free resources accordingly, and update calls
in the code paths that reference cmd and target.
In `@clib-masterllvm-15/src/clib.c`:
- Around line 84-94: In compare_versions, guard against
clib_release_get_latest_tag() returning NULL before calling strcmp and free:
call clib_release_get_latest_tag(), check if latest_version is NULL and skip the
version comparison/logging (or log a different message) to avoid passing NULL to
strcmp, then only call free on a non-NULL latest_version; also fix the typo in
the logger_info message ("avalable" -> "available") and keep CLIB_VERSION and
latest_version as the logged values.
In `@clib-masterllvm-15/src/common/clib-cache.c`:
- Around line 26-30: The code uses BASE_DIR defined as getenv("HOME") or
getenv("AppData") which can be NULL and is later passed into sprintf in
clib_cache_init() and clib_cache_meta_init(); fix by replacing the bare getenv
usage with a safe helper or inline NULL check: fetch the env var into a local
char* (e.g., base_dir = getenv("HOME") / getenv("AppData")), if base_dir is NULL
set a sensible fallback (e.g., use "." or another platform-appropriate fallback
like getenv("USERPROFILE") on Windows) or return an error from
clib_cache_init()/clib_cache_meta_init(); then use that validated base_dir in
the subsequent sprintf calls instead of BASE_DIR to avoid dereferencing NULL.
In `@clib-masterllvm-15/src/common/clib-package.c`:
- Around line 1218-1224: The code builds a new string in flags using asprintf
but then calls setenv("CFLAGS", cflags, 1) and leaks flags; change the call to
setenv to use the newly allocated flags (setenv("CFLAGS", flags, 1)) and
free(flags) after setenv; also ensure you handle asprintf failures (check return
value != -1) before calling setenv or free to avoid using NULL/invalid pointers;
update references around the asprintf/flags/cflags logic (symbols: flags,
cflags, pkg->flags, asprintf, setenv) accordingly.

504-513: Memory corruption: assigning string literal then passing toasprintf.When
pkg->flagsis NULL, it's assigned""(a string literal), then passed toasprintfwhich reads from it. This works for reading, but the subsequentfree(flag)is fine. However, on the next iteration,pkg->flagsnow points to heap memory fromasprintf, but the initial assignment to""causes issues if the first flag is processed - the oldpkg->flags(empty string literal) cannot be freed.More critically: after the loop, if flags were found,
pkg->flagspoints to heap memory. But the initialpkg->flags = ""assignment means the firstasprintfcall formats with a string literal, which is fine. The issue is the pattern is fragile.🐛 Proposed fix

620-642: Fix memory leaks and unsafe basename/dirname usage.The code has multiple critical issues:
Memory leak from

realpath()error check: At line 622,realpath(dep, dir)can return NULL on failure, but the code doesn't check for this, leading to NULL pointer usage downstream.Unsafe
basename()/dirname()usage: At lines 634–635, the code callsbasename(dep)which mutates the input buffer and overwritesdepwith the result, then callsdirname(dep)andbasename(dep)again on the already-modified buffer. Since POSIX allows these functions to modify their input and return pointers into the modified buffer, this is unsafe and loses the directory path.Track whether
depwas allocated bypath_join()and free it at the end of each loop iteration. Guardrealpath()andpath_join()calls for NULL. Make independent copies ofdepbefore passing tobasename()anddirname().clib-masterllvm-15/src/clib-configure.c-166-171 (1)
166-171: Race condition in deduplication check: hash_has occurs outside critical section.The
hash_hascheck at line 166 (and similarly at 210-213 and 256-257) happens under the mutex, but the mutex is released immediately after (lines 169 and 173). The actualhash_setcall happens much later after releasing and re-acquiring the mutex. This creates a time-of-check to time-of-use (TOCTOU) race: two threads can both observe the key missing, both perform configuration work, and both insert into the hash.While the hash itself is string-keyed (using
strcmpcomparison) and will correctly match identical paths, the synchronization is broken. The check and insertion must be atomic under the mutex. Restructure to acquire the mutex only once and perform both check and insertion while holding it, or mark entries as "in-progress" before releasing the mutex.

84-98: Inverted return value semantics inwrite_to_file.The function returns
length - wrote, meaning it returns0on success (all bytes written). However, inwrite_package_file(line 104), the check0 != write_to_file(...)treats non-zero as an error. Iffwritepartially writes, this logic is correct, but iffwritefails completely and returns 0, the function returnslengthwhich would be treated as an error—this is actually correct behavior, but the semantics are confusing.Consider returning a clearer success/failure indicator.
♻️ Suggested refactor for clarity
static inline size_t write_to_file(const char *manifest, const char *str, size_t length) { - size_t wrote = 0; - FILE *file = fopen(manifest, "w+"); if (!file) { debug(&debugger, "Cannot open %s file.", manifest); - return 0; + return 1; } - wrote = fwrite(str, sizeof(char), length, file); + size_t wrote = fwrite(str, sizeof(char), length, file); fclose(file); - return length - wrote; + return (wrote == length) ? 0 : 1; }This makes the return value clearly
0for success and non-zero for failure.

Variable shadowing causes clean command to be lost.
The inner char *clean = 0; at line 254 shadows the outer char *clean = 0; declared at line 218. The asprintf assigns to the inner variable, which goes out of scope immediately. The outer clean remains NULL, so the clean command is never executed.

@Achillesed，根据 clib_package_new_from_slug 的实现代码（在 src/common/clib-package.c 中），该函数在以下几种情况下会返回 NULL：
函数返回 NULL 的场景：
- 无效的 slug 格式：如果 slug 为空或格式不正确，无法解析出 author/name/version
- 网络请求失败：从 GitHub 获取包的 manifest 文件（
clib.json或package.json）失败，重试 3 次后仍失败 - 包不存在：指定的 GitHub 仓库或版本不存在，HTTP 返回 404 等错误
- JSON 解析失败：获取到的 manifest 内容不是有效的 JSON 格式，或缺少必需字段
- 内存分配失败：URL 构建、字符串复制等操作时内存不足
- repo 构建失败：无法构建有效的 repository 字符串
从代码第 771-789 行可以看到，当遇到错误时会跳转到 error: 标签，清理资源并返回 NULL：
error:
if (0 == retries) {
if (verbose && author && name && file) {
logger_warn("warning", "unable to fetch %s/%s:%s", author, name, file);
}
}
// ... cleanup and free resources ...
return NULL;因此，您原先的建议是正确的——在调用 clib_package_new_from_slug 后，必须检查返回值是否为 NULL，否则后续访问 dependency->name 会导致空指针解引用，造成程序崩溃。
建议的修复方案是合理的：在访问 dependency->name 之前先检查 dependency 是否为 NULL，如果是则处理错误（释放资源、设置错误码、跳转到 cleanup）。

Clamp concurrency to prevent VLA exploitation and undefined behavior.
opts.concurrency is assigned directly from atol(self->arg) without validation. Since atol() returns a long (signed) and opts.concurrency is unsigned int, negative inputs wrap around to huge values, and zero creates invalid zero-length VLAs. This occurs at three locations (lines 280-282, 351-353, and the setopt_concurrency function at 486-498). Validate and clamp the value immediately after parsing.

Fix NULL pointer dereferences and missing error handling in both dependency loops.
clib_package_new_from_slug can return NULL, and the code immediately dereferences dependency->name without checking. Additionally, path_join can fail and return NULL. In the pthread path, neither error is checked, and pthread_create failures are ignored. The non-pthread path has a partial check for dep_dir but still lacks NULL validation for dependency. Add NULL checks after both function calls and validate pthread_create return values before proceeding.
Applies to both the dependencies loop (lines 288-304) and development-dependencies loop (lines 358-374).

Off-by-one / incorrect boundary check in getinput.

Replace system() calls with execv() or posix_spawn() to prevent shell injection.
The cmd string at line 172 embeds the file parameter (derived from user-supplied name/version) directly into a shell command without escaping. A package name like foo; rm -rf / would execute arbitrary commands. Similarly, target at line 181 executes the uninstall field from the package manifest (loaded from the tarball) via system(), allowing manifest injection attacks.
Use execv() or posix_spawn() with explicit argv arrays instead. For the tar command, construct argv as ["tar", "-xf", file] (with proper quoting for the file path). For manifest commands, either parse the uninstall field into argv elements or maintain an allow-list of safe commands.

Null pointer dereference in compare_versions.
clib_release_get_latest_tag() can return NULL (as seen in the relevant code snippet from clib-release-info.c). Calling strcmp with a NULL argument causes undefined behavior/crash.
Also, there's a typo: "avalable" should be "available".

Potential NULL pointer dereference from getenv().
getenv("HOME") or getenv("AppData") can return NULL if the environment variable is not set. This NULL value is then used in sprintf() calls throughout the code (e.g., lines 64, 78-80), which will cause undefined behavior or crashes.

Bug: flags is allocated but cflags is set to CFLAGS environment variable.

多数 memset/memcpy 警告（clang-tidy）属于误报，因为这些函数用于已知大小的栈数组，且长度通过 path_max 控制。但为提升代码健壮性，建议： 1 在 path_max 计算后添加有效性检查：if (path_max <= 0 || path_max > 4096) path_max = 4096; 总结：本次新增代码功能完整，但存在多处安全与可靠性隐患，尤其是命令注入和内存管理问题。建议优先修复高风险的命令注入和并发数据竞争，其次处理内存 批次 2/2（10 个文件）

Let me check if Actually, looking at the code, I see references to: 1 list/list.h in clib-package.h - not in chat But since these are dependencies, they might be in the deps/ directory.

This should be Also, the function doesn't null-terminate the buffer, which could cause issues when strlen is called later.
