Subject: [PATCH 0/8] posix: glob fixes and refactor
Date: Tue, 21 Nov 2017 13:55:00 -0000 [thread overview]
Message-ID: <1511272530-10936-1-git-send-email-adhemerval.zanella@linaro.org> (raw)
This patchset main target is to remove alloca usage on glob by
using a specialized dynarray for C strings (struct char_array).
It does not change any glob semantics, only internal glob buffer
management. It also does not solve the potential stack overflow
due recursive allocation from wildcard in patterns [1] (although
an option would be go to pure dynamic char_array for this case).
