13 | /* XXX struct tm on some systems (SunOS4/BSD) contains extra (non POSIX) | |
d4d72fe6 | 14 | * fields for which we don't have Configure support prior to Perl 5.8.0: |
16433e2b SP |
15 | * char *tm_zone; -- abbreviation of timezone name |
16 | * long tm_gmtoff; -- offset from GMT in seconds | |
17 | * To workaround core dumps from the uninitialised tm_zone we get the | |
18 | * system to give us a reasonable struct to copy. This fix means that | |
19 | * strftime uses the tm_zone and tm_gmtoff values returned by | |
20 | * localtime(time()). That should give the desired result most of the | |
21 | * time. But probably not always! | |
22 | * | |
d4d72fe6 CB |
23 | * This is a vestigial workaround for Perls prior to 5.8.0. We now |
24 | * rely on the initialization (still likely a workaround) in util.c. | |

75 | * (1) The CRT maintains its own copy of the environment, separate from | |
76 | * the Win32API copy. | |
77 | * | |
78 | * (2) CRT getenv() retrieves from this copy. CRT putenv() updates this | |
79 | * copy, and then calls SetEnvironmentVariableA() to update the Win32API | |
80 | * copy. | |
81 | * | |
82 | * (3) win32_getenv() and win32_putenv() call GetEnvironmentVariableA() and | |
83 | * SetEnvironmentVariableA() directly, bypassing the CRT copy of the | |
84 | * environment. | |
85 | * | |
86 | * (4) The CRT strftime() "%Z" implementation calls __tzset(). That | |
87 | * calls CRT tzset(), but only the first time it is called, and in turn | |
88 | * that uses CRT getenv("TZ") to retrieve the timezone info from the CRT | |
89 | * local copy of the environment and hence gets the original setting as | |
90 | * perl never updates the CRT copy when assigning to $ENV{TZ}. | |
91 | * | |
92 | * Therefore, we need to retrieve the value of $ENV{TZ} and call CRT | |
12016aad SH |
93 | * putenv() to update the CRT copy of the environment (if it is different) |
94 | * whenever we're about to call tzset(). | |
95 | * | |
96 | * In addition to all that, when perl is built with PERL_IMPLICIT_SYS | |
97 | * defined: | |
98 | * | |
99 | * (a) Each interpreter has its own copy of the environment inside the | |
100 | * perlhost structure. That allows applications that host multiple | |
101 | * independent Perl interpreters to isolate environment changes from | |
102 | * each other. (This is similar to how the perlhost mechanism keeps a | |
103 | * separate working directory for each Perl interpreter, so that calling | |
104 | * chdir() will not affect other interpreters.) | |
105 | * | |
106 | * (b) Only the first Perl interpreter instantiated within a process will | |
107 | * "write through" environment changes to the process environment. | |
108 | * | |
109 | * (c) Even the primary Perl interpreter won't update the CRT copy of the | |
110 | * the environment, only the Win32API copy (it calls win32_putenv()). | |
111 | * | |
112 | * As with CPerlHost::Getenv() and CPerlHost::Putenv() themselves, it makes | |
113 | * sense to only update the process environment when inside the main | |
114 | * interpreter, but we don't have access to CPerlHost's m_bTopLevel member | |
115 | * from here so we'll just have to check PL_curinterp instead. | |
116 | * | |
117 | * Therefore, we can simply #undef getenv() and putenv() so that those names | |
118 | * always refer to the CRT functions, and explicitly call win32_getenv() to | |
119 | * access perl's %ENV. | |
120 | * | |
121 | * We also #undef malloc() and free() to be sure we are using the CRT | |
122 | * functions otherwise under PERL_IMPLICIT_SYS they are redefined to calls | |
123 | * into VMem::Malloc() and VMem::Free() and all allocations will be freed | |
124 | * when the Perl interpreter is being destroyed so we'd end up with a pointer | |
125 | * into deallocated memory in environ[] if a program embedding a Perl | |
126 | * interpreter continues to operate even after the main Perl interpreter has | |
127 | * been destroyed. | |
128 | * | |
129 | * Note that we don't free() the malloc()ed memory unless and until we call | |
130 | * malloc() again ourselves because the CRT putenv() function simply puts its | |
131 | * pointer argument into the environ[] arrary (it doesn't make a copy of it) | |
132 | * so this memory must otherwise be leaked. | |
