e3a06a3c6cbb288ac89a2725cf71ae8adaebf35c test: Add `strerror` to locale-dependence linter (laanwj) f00fb1265a8bc26e1612c771173325dbe49b3612 util: Increase buffer size to 1024 in SysErrorString (laanwj) 718da302c7b11b375042c3000d421fd93348c199 util: Refactor SysErrorString logic (laanwj) e7f2f77756d33c6be9c8998a575b263ff2d39270 util: Use strerror_s for SysErrorString on Windows (laanwj) 46971c6dbfbc39ebbc74ab1ed8c00edc12859373 util: Replace non-threadsafe strerror (laanwj) Pull request description: Some uses of non-threadsafe `strerror` have snuck into the code since they were removed in #4152. Add a wrapper `SysErrorString` for thread-safe strerror alternatives (with code from `NetworkErrorString`) and replace all uses of `strerror` with this. Edit: I've also added a commit that refactors the code so that buf[] is never read at all if the function fails, making some fragile-looking code unnecessary. Edit2: from the linux manpage: ``` ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌───────────────────┬───────────────┬─────────────────────────┐ │Interface │ Attribute │ Value │ ├───────────────────┼───────────────┼─────────────────────────┤ │strerror() │ Thread safety │ MT-Unsafe race:strerror │ ├───────────────────┼───────────────┼─────────────────────────┤ … ├───────────────────┼───────────────┼─────────────────────────┤ │strerror_r(), │ Thread safety │ MT-Safe │ │strerror_l() │ │ │ └───────────────────┴───────────────┴─────────────────────────┘ ``` As the function can be called from any thread at any time, using a non-thread-safe function is unacceptable.
