| 1290 | * |
| 1291 | * (2) CRT getenv() retrieves from this copy. CRT putenv() updates this |
| 1292 | * copy, and then calls SetEnvironmentVariableA() to update the Win32API |
| 1293 | * copy. |
| 1294 | * |
| 1295 | * (3) win32_getenv() and win32_putenv() call GetEnvironmentVariableA() and |
| 1296 | * SetEnvironmentVariableA() directly, bypassing the CRT copy of the |
| 1297 | * environment. |
| 1298 | * |
| 1299 | * (4) The CRT strftime() "%Z" implementation calls __tzset(). That |
| 1300 | * calls CRT tzset(), but only the first time it is called, and in turn |
| 1301 | * that uses CRT getenv("TZ") to retrieve the timezone info from the CRT |
| 1302 | * local copy of the environment and hence gets the original setting as |
| 1303 | * perl never updates the CRT copy when assigning to $ENV{TZ}. |
| 1304 | * |
| 1305 | * Therefore, we need to retrieve the value of $ENV{TZ} and call CRT |
| 1306 | * putenv() to update the CRT copy of the environment (if it is different) |
| 1307 | * whenever we're about to call tzset(). |
| 1308 | * |
| 1309 | * In addition to all that, when perl is built with PERL_IMPLICIT_SYS |
| 1310 | * defined: |
| 1311 | * |
| 1312 | * (a) Each interpreter has its own copy of the environment inside the |
| 1313 | * perlhost structure. That allows applications that host multiple |
| 1314 | * independent Perl interpreters to isolate environment changes from |
| 1315 | * each other. (This is similar to how the perlhost mechanism keeps a |
| 1316 | * separate working directory for each Perl interpreter, so that calling |
| 1317 | * chdir() will not affect other interpreters.) |
| 1318 | * |
| 1319 | * (b) Only the first Perl interpreter instantiated within a process will |
| 1320 | * "write through" environment changes to the process environment. |
| 1321 | * |
| 1322 | * (c) Even the primary Perl interpreter won't update the CRT copy of the |
| 1323 | * the environment, only the Win32API copy (it calls win32_putenv()). |
| 1324 | * |
| 1325 | * As with CPerlHost::Getenv() and CPerlHost::Putenv() themselves, it makes |
| 1326 | * sense to only update the process environment when inside the main |
| 1327 | * interpreter, but we don't have access to CPerlHost's m_bTopLevel member |
| 1328 | * from here so we'll just have to check PL_curinterp instead. |
| 1329 | * |
| 1330 | * Therefore, we can simply #undef getenv() and putenv() so that those names |
| 1331 | * always refer to the CRT functions, and explicitly call win32_getenv() to |
| 1332 | * access perl's %ENV. |
| 1333 | * |
| 1334 | * We also #undef malloc() and free() to be sure we are using the CRT |
| 1335 | * functions otherwise under PERL_IMPLICIT_SYS they are redefined to calls |
| 1336 | * into VMem::Malloc() and VMem::Free() and all allocations will be freed |
| 1337 | * when the Perl interpreter is being destroyed so we'd end up with a pointer |
| 1338 | * into deallocated memory in environ[] if a program embedding a Perl |
| 1339 | * interpreter continues to operate even after the main Perl interpreter has |
| 1340 | * been destroyed. |
| 1341 | * |
| 1342 | * Note that we don't free() the malloc()ed memory unless and until we call |
| 1343 | * malloc() again ourselves because the CRT putenv() function simply puts its |
| 1344 | * pointer argument into the environ[] array (it doesn't make a copy of it) |
| 1345 | * so this memory must otherwise be leaked. |
