1275 | * (1) The CRT maintains its own copy of the environment, separate from | |
1276 | * the Win32API copy. | |
1277 | * | |
1278 | * (2) CRT getenv() retrieves from this copy. CRT putenv() updates this | |
1279 | * copy, and then calls SetEnvironmentVariableA() to update the Win32API | |
1280 | * copy. | |
1281 | * | |
1282 | * (3) win32_getenv() and win32_putenv() call GetEnvironmentVariableA() and | |
1283 | * SetEnvironmentVariableA() directly, bypassing the CRT copy of the | |
1284 | * environment. | |
1285 | * | |
1286 | * (4) The CRT strftime() "%Z" implementation calls __tzset(). That | |
1287 | * calls CRT tzset(), but only the first time it is called, and in turn | |
1288 | * that uses CRT getenv("TZ") to retrieve the timezone info from the CRT | |
1289 | * local copy of the environment and hence gets the original setting as | |
1290 | * perl never updates the CRT copy when assigning to $ENV{TZ}. | |
1291 | * | |
1292 | * Therefore, we need to retrieve the value of $ENV{TZ} and call CRT | |
1293 | * putenv() to update the CRT copy of the environment (if it is different) | |
1294 | * whenever we're about to call tzset(). | |
1295 | * | |
1296 | * In addition to all that, when perl is built with PERL_IMPLICIT_SYS | |
1297 | * defined: | |
1298 | * | |
1299 | * (a) Each interpreter has its own copy of the environment inside the | |
1300 | * perlhost structure. That allows applications that host multiple | |
1301 | * independent Perl interpreters to isolate environment changes from | |
1302 | * each other. (This is similar to how the perlhost mechanism keeps a | |
1303 | * separate working directory for each Perl interpreter, so that calling | |
1304 | * chdir() will not affect other interpreters.) | |
1305 | * | |
1306 | * (b) Only the first Perl interpreter instantiated within a process will | |
1307 | * "write through" environment changes to the process environment. | |
1308 | * | |
1309 | * (c) Even the primary Perl interpreter won't update the CRT copy of the | |
1310 | * the environment, only the Win32API copy (it calls win32_putenv()). | |
1311 | * | |
1312 | * As with CPerlHost::Getenv() and CPerlHost::Putenv() themselves, it makes | |
1313 | * sense to only update the process environment when inside the main | |
1314 | * interpreter, but we don't have access to CPerlHost's m_bTopLevel member | |
1315 | * from here so we'll just have to check PL_curinterp instead. | |
1316 | * | |
1317 | * Therefore, we can simply #undef getenv() and putenv() so that those names | |
1318 | * always refer to the CRT functions, and explicitly call win32_getenv() to | |
1319 | * access perl's %ENV. | |
1320 | * | |
1321 | * We also #undef malloc() and free() to be sure we are using the CRT | |
1322 | * functions otherwise under PERL_IMPLICIT_SYS they are redefined to calls | |
1323 | * into VMem::Malloc() and VMem::Free() and all allocations will be freed | |
1324 | * when the Perl interpreter is being destroyed so we'd end up with a pointer | |
1325 | * into deallocated memory in environ[] if a program embedding a Perl | |
1326 | * interpreter continues to operate even after the main Perl interpreter has | |
1327 | * been destroyed. | |
1328 | * | |
1329 | * Note that we don't free() the malloc()ed memory unless and until we call | |
1330 | * malloc() again ourselves because the CRT putenv() function simply puts its | |
b7b1e41b | 1331 | * pointer argument into the environ[] array (it doesn't make a copy of it) |
81ab4c44 SH |
1332 | * so this memory must otherwise be leaked. |
