That is, +when executing `foo` from the command line, the shell sets `_` to +`/usr/bin/foo` (assuming that's where foo is). + +However, nothing else does the same, so when e.g. a python program uses +`subprocess.Popen` to run another program, it doesn't set `_`. Worse, if that +python program itself was invoked from a shell, `_` would be set to e.g. +`/usr/bin/python3`. + +So when nsis is invoked from a program that is not a shell, but the process +ancestry has a process that was a shell, `_` may be set to the first +intermediary program rather than nsis, which defeats nsis's assumption that `_` +would contain the nsis path. Ironically, nsis also has more reliable fallbacks +(using e.g. /proc/self/exe), but somehow prefers `_`. + +We remove the reliance of `_` entirely, for simplicity's sake. + + +diff -ruN nsis-3.07-src.orig/Source/util.cpp nsis-3.07-src/Source/util.cpp +--- nsis-3.07-src.orig/Source/util.cpp 2021-09-02 09:25:48.489016918 +0900 ++++ nsis-3.07-src/Source/util.cpp 2021-09-02 09:26:21.158814484 +0900 +@@ -810,10 +810,7 @@ + assert(rc == 0); + return tstring(CtoTString(temp_buf)); + #else /* Linux/BSD/POSIX/etc */ +- const TCHAR *envpath = _tgetenv(_T("_")); +- if (envpath) +- return get_full_path(envpath); +- else { ++ { + char *path = NULL, *pathtmp; + size_t len = 100; + int nchars; |
