ext/session/mod_mm: initialize mm instance in open handler #21192
Conversation
…n MINIT This remove access to the globals that could very much change during the execution of the script and prior to opening the session handler

Will this not cause race conditions in zts? |
The MM module does not support ZTS and has a preprocessor error defined: #ifdef ZTS
# error mm is not thread-safe
#endif |
|
that s one of the reason I wanted to move away from libmm ... this and how very obsolete it is. |
|
do you plan any more change @Girgias ? |

one little nit not related to your change, uid_t is unsigned int on linux.

| memcpy(ps_mm_path + save_path_len, PS_MM_FILE, sizeof(PS_MM_FILE) - 1); |

only if you want, but we may be able to simplify a bit using zend_mempcpy instead.

Sorry currently at a conference, but I might do the fixes like this for uid_t and zend_mempcpy() to not mix concerns within this PR.

Currently wondering if we might not be leaking memory if we close the session handler and open a new one after changing the name (or effectively reusing the same one). |

Rather than doing this in MINIT.
This remove access to the globals that could very much change during the execution of the script and prior to opening the session handler.
