1718 | * (1) The CRT maintains its own copy of the environment, separate from | |
1719 | * the Win32API copy. | |
1720 | * | |
1721 | * (2) CRT getenv() retrieves from this copy. CRT putenv() updates this | |
1722 | * copy, and then calls SetEnvironmentVariableA() to update the Win32API | |
1723 | * copy. | |
1724 | * | |
1725 | * (3) win32_getenv() and win32_putenv() call GetEnvironmentVariableA() and | |
1726 | * SetEnvironmentVariableA() directly, bypassing the CRT copy of the | |
1727 | * environment. | |
1728 | * | |
1729 | * (4) The CRT strftime() "%Z" implementation calls __tzset(). That | |
1730 | * calls CRT tzset(), but only the first time it is called, and in turn | |
1731 | * that uses CRT getenv("TZ") to retrieve the timezone info from the CRT | |
1732 | * local copy of the environment and hence gets the original setting as | |
1733 | * perl never updates the CRT copy when assigning to $ENV{TZ}. | |
1734 | * | |
1735 | * Therefore, we need to retrieve the value of $ENV{TZ} and call CRT | |
1736 | * putenv() to update the CRT copy of the environment (if it is different) | |
1737 | * whenever we're about to call tzset(). | |
1738 | * | |
1739 | * In addition to all that, when perl is built with PERL_IMPLICIT_SYS | |
1740 | * defined: | |
1741 | * | |
1742 | * (a) Each interpreter has its own copy of the environment inside the | |
1743 | * perlhost structure. That allows applications that host multiple | |
1744 | * independent Perl interpreters to isolate environment changes from | |
1745 | * each other. (This is similar to how the perlhost mechanism keeps a | |
1746 | * separate working directory for each Perl interpreter, so that calling | |
1747 | * chdir() will not affect other interpreters.) | |
1748 | * | |
1749 | * (b) Only the first Perl interpreter instantiated within a process will | |
1750 | * "write through" environment changes to the process environment. | |
1751 | * | |
1752 | * (c) Even the primary Perl interpreter won't update the CRT copy of the | |
1753 | * the environment, only the Win32API copy (it calls win32_putenv()). | |
1754 | * | |
1755 | * As with CPerlHost::Getenv() and CPerlHost::Putenv() themselves, it makes | |
1756 | * sense to only update the process environment when inside the main | |
1757 | * interpreter, but we don't have access to CPerlHost's m_bTopLevel member | |
1758 | * from here so we'll just have to check PL_curinterp instead. | |
1759 | * | |
1760 | * Therefore, we can simply #undef getenv() and putenv() so that those names | |
1761 | * always refer to the CRT functions, and explicitly call win32_getenv() to | |
1762 | * access perl's %ENV. | |
1763 | * | |
1764 | * We also #undef malloc() and free() to be sure we are using the CRT | |
1765 | * functions otherwise under PERL_IMPLICIT_SYS they are redefined to calls | |
1766 | * into VMem::Malloc() and VMem::Free() and all allocations will be freed | |
1767 | * when the Perl interpreter is being destroyed so we'd end up with a pointer | |
1768 | * into deallocated memory in environ[] if a program embedding a Perl | |
1769 | * interpreter continues to operate even after the main Perl interpreter has | |
1770 | * been destroyed. | |
1771 | * | |
1772 | * Note that we don't free() the malloc()ed memory unless and until we call | |
1773 | * malloc() again ourselves because the CRT putenv() function simply puts its | |
b7b1e41b | 1774 | * pointer argument into the environ[] array (it doesn't make a copy of it) |
81ab4c44 SH |
1775 | * so this memory must otherwise be leaked. |
