533 | * (1) The CRT maintains its own copy of the environment, separate from | |
534 | * the Win32API copy. | |
535 | * | |
536 | * (2) CRT getenv() retrieves from this copy. CRT putenv() updates this | |
537 | * copy, and then calls SetEnvironmentVariableA() to update the Win32API | |
538 | * copy. | |
539 | * | |
540 | * (3) win32_getenv() and win32_putenv() call GetEnvironmentVariableA() and | |
541 | * SetEnvironmentVariableA() directly, bypassing the CRT copy of the | |
542 | * environment. | |
543 | * | |
544 | * (4) The CRT strftime() "%Z" implementation calls __tzset(). That | |
545 | * calls CRT tzset(), but only the first time it is called, and in turn | |
546 | * that uses CRT getenv("TZ") to retrieve the timezone info from the CRT | |
547 | * local copy of the environment and hence gets the original setting as | |
548 | * perl never updates the CRT copy when assigning to $ENV{TZ}. | |
549 | * | |
550 | * Therefore, we need to retrieve the value of $ENV{TZ} and call CRT | |
551 | * putenv() to update the CRT copy of the environment (if it is different) | |
552 | * whenever we're about to call tzset(). | |
553 | * | |
554 | * In addition to all that, when perl is built with PERL_IMPLICIT_SYS | |
555 | * defined: | |
556 | * | |
557 | * (a) Each interpreter has its own copy of the environment inside the | |
558 | * perlhost structure. That allows applications that host multiple | |
559 | * independent Perl interpreters to isolate environment changes from | |
560 | * each other. (This is similar to how the perlhost mechanism keeps a | |
561 | * separate working directory for each Perl interpreter, so that calling | |
562 | * chdir() will not affect other interpreters.) | |
563 | * | |
564 | * (b) Only the first Perl interpreter instantiated within a process will | |
565 | * "write through" environment changes to the process environment. | |
566 | * | |
567 | * (c) Even the primary Perl interpreter won't update the CRT copy of the | |
568 | * the environment, only the Win32API copy (it calls win32_putenv()). | |
569 | * | |
570 | * As with CPerlHost::Getenv() and CPerlHost::Putenv() themselves, it makes | |
571 | * sense to only update the process environment when inside the main | |
572 | * interpreter, but we don't have access to CPerlHost's m_bTopLevel member | |
573 | * from here so we'll just have to check PL_curinterp instead. | |
574 | * | |
575 | * Therefore, we can simply #undef getenv() and putenv() so that those names | |
576 | * always refer to the CRT functions, and explicitly call win32_getenv() to | |
577 | * access perl's %ENV. | |
578 | * | |
579 | * We also #undef malloc() and free() to be sure we are using the CRT | |
580 | * functions otherwise under PERL_IMPLICIT_SYS they are redefined to calls | |
581 | * into VMem::Malloc() and VMem::Free() and all allocations will be freed | |
582 | * when the Perl interpreter is being destroyed so we'd end up with a pointer | |
583 | * into deallocated memory in environ[] if a program embedding a Perl | |
584 | * interpreter continues to operate even after the main Perl interpreter has | |
585 | * been destroyed. | |
586 | * | |
587 | * Note that we don't free() the malloc()ed memory unless and until we call | |
588 | * malloc() again ourselves because the CRT putenv() function simply puts its | |
b7b1e41b | 589 | * pointer argument into the environ[] array (it doesn't make a copy of it) |
81ab4c44 SH |
590 | * so this memory must otherwise be leaked. |
