For the optimization purpose, function nxt_unit_remove_process() expects
lib->mutex to be locked. The function then moves ports queue into temporary
queue and releases mutex. In nxt_unit_done() there were two errors: mutex was
not locked before nxt_unit_remove_process() call and mutex was not destroyed.
It is hard to tell what was possible negative impact of this errors.

Overriding LANG might not work, since it has less precedence than LC_* settings.
LC_ALL has the highest precedence.
This should resolve issue #121 on GitHub.
Changeset #699 fixes shared memory allocation: continous buffer with
requested size should be allocated or function failed. For body longer
than 10 Mb, this allocation will definitely fails.
For body buffer it is not required to send it in a single continous buffer,
so, need to request minimum reasonable amount of shared memory and try to
extend it, if possible or allocate next buffer.
It has the following structure and default values:
{
"http": {
"header_read_timeout": 30,
"body_read_timeout": 30,
"send_timeout": 30,
"idle_timeout": 180,
"max_body_size": 8388608
}
}
The implementation of module was based on the assumption that PHP reads request
body and headers in the particular order. For the POST request the body goes
before headers and vice versa for all other requests.
But as it appeared later, this order is unspecified and depends on many factors,
including the particular code of PHP application. Among other factors those
can affect ordering:
- presence of "Content-Type" header;
- "variables_order" php.ini setting;
- "enable_post_data_reading" php.ini setting;
- reading php://input by application;
and this list can be incomplete.
As a temporary workaround, request body now is always put before headers and it
is gracefully skipped whenever PHP wants to get headers.
This closes#144 issue on GitHub.
The previous method changed PHP options only for the first request.
On the request completion the options were rolled back.
This closes#145 issue on GitHub.
Allowing characters up to 0xFF doesn't conflict with RFC 7230.
Particularly, this make it possible to pass unencoded UTF-8 data
through HTTP headers, which can be useful.
Previously, one shared memory chunk was allocated under mutex and other
chunks (if required) were allocated using atomic operations. So such
allocation is not guaranteed and the result buffer can be less than
requested.
This commit moves multiple chunks allocation under mutex and guarantees
the result buffer is large enough.
