From: Ronan Desplanques <desplanq...@adacore.com> Before this patch, Ada.Directories.Modification_Time called GetFileAttributesExA under the hood on Windows. That would sometimes fail to work with files whose names were non-ASCII.
This patch replaces the call to GetFileAttributesExA with a call to GetFileAttributesEx preceded by an encoding scheme conversion, as is done in other functions of the run-time library. This fixes the issues that were observed with the previous implementations. gcc/ada/ * adaint.c (__gnat_file_time): Fix Windows version. Tested on x86_64-pc-linux-gnu, committed on master. --- gcc/ada/adaint.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/gcc/ada/adaint.c b/gcc/ada/adaint.c index 2a193efc002..bb4ed2607e5 100644 --- a/gcc/ada/adaint.c +++ b/gcc/ada/adaint.c @@ -1507,7 +1507,16 @@ extern long long __gnat_file_time(char* name) long long ll_time; } t_write; - if (!GetFileAttributesExA(name, GetFileExInfoStandard, &fad)) { + TCHAR wname [GNAT_MAX_PATH_LEN + 2]; + int name_len; + + S2WSC (wname, name, GNAT_MAX_PATH_LEN + 2); + name_len = _tcslen (wname); + + if (name_len > GNAT_MAX_PATH_LEN) + return LLONG_MIN; + + if (!GetFileAttributesEx(wname, GetFileExInfoStandard, &fad)) { return LLONG_MIN; } -- 2.42.0
