RipGrep x86_64-unknown-linux-musl Binaries SIGSEGV Xatoligi

RipGrep 15.2.0 versiyasi x86_64-unknown-linux-musl uchun SIGSEGV xatoliklarini keltirib chiqarishi haqida ma'lumot berilmoqda. Bu xatolik juda katta fayl tizimlarini qidirish paytida, yuqori darajadagi konkurentlikda paydo bo'lishi mumkin.

Xatolik Haqida

Xatolik MUSL mallocng xotirani boshqarishida, opendir funksiyasidan calloc chaqirilganda paydo bo'ladi. Bu xatolik x86_64-unknown-linux-musl arxitekturasida qurilgan RipGrep 15.2.0 versiyasi uchun kuzatilgan.

Reproduksiya Qilish

Xatolikni reproduksiya qilish uchun katta fayl tizimini yaratish va unda yuqori darajadagi konkurentlikda qidiruv amalini bajarish kerak. Buning uchun generate_repro_tree.py dasturi yordamida katta fayl tizimini yaratish mumkin.

Backtrace

Xatolik paydo bo'lganda, quyidagi backtrace keltirib chiqariladi:

#0 get_meta () at ../src_musl/src/malloc/mallocng/meta.h:141
#1 __malloc_allzerop () at ../src_musl/src/malloc/mallocng/malloc.c:384
#2 0x00007f71f8381b2d in calloc () at ../src_musl/src/malloc/calloc.c:41
#3 0x00007f71f83810f4 in opendir () at ../src_musl/src/dirent/opendir.c:15
...
   

Kutilayotgan Xulq

Kutilayotgan xulq shundaki, RipGrep SIGSEGV xatoligini keltirib chiqarmasligi kerak.
