From a Unix point of view, some other platform families have certain quirks. Windows command prompt doesn't expand globs into actual file names, so we must do this. VMS has some oddity with argv pointer size that can cause crashes if you're not careful (by copying it to a less surprising pointer size array). The fixups already exist and are used in the apps/ code. However, the testutil code started using the opt routines from apps/ without including the non-Unix fixups. This change fixes that. For VMS' sake, libtestutil gets an app_malloc() shim, to avoid sucking in all of apps/apps.c. Reviewed-by: Paul Dale <paul.dale@oracle.com> (Merged from https://github.com/openssl/openssl/pull/8381)

|
|
* If we have 32-bit pointers everywhere, then we're safe, and
|
|
* we bypass this mess, as on non-VMS systems.
|
|
* Problem 1: Compaq/HP C before V7.3 always used 32-bit
|
|
* pointers for argv[].
|
|
* Fix 1: For a 32-bit argv[], when we're using 64-bit pointers
|
|
* everywhere else, we always allocate and use a 64-bit
|
|
* duplicate of argv[].
|
|
* Problem 2: Compaq/HP C V7.3 (Alpha, IA64) before ECO1 failed
|
|
* to NULL-terminate a 64-bit argv[]. (As this was written, the
|
|
* compiler ECO was available only on IA64.)
|
|
* Fix 2: Unless advised not to (VMS_TRUST_ARGV), we test a
|
|
* 64-bit argv[argc] for NULL, and, if necessary, use a
|
|
* (properly) NULL-terminated (64-bit) duplicate of argv[].
|
|
* The same code is used in either case to duplicate argv[].
|
|
* Some of these decisions could be handled in preprocessing,
|
|
* but the code tends to get even uglier, and the penalty for
|
|
* deciding at compile- or run-time is tiny.
