with this I would like to save the time when the first byte was received by
httpd and later save it in request_rec->notes.
Note that a connection input filter will have the structure request_rec
unitialized.

Subject: Input filters + apr_time_exp_lt/apr_time_now thread safety
Hi,
I am using apache 2.2.14 with worker mpm.
My module does the following:
- my module config structure records two time values :
config->time_request_in and config->time_request_in_end; they are allocated in
child_init:
config->time_request_in = apr_pcalloc(pool, sizeof (apr_time_exp_t));
- in an Connection input filter I record the time_request_in as follows:
ap_register_input_filter(my_filter_name, in_filter_start,NULL,
AP_FTYPE_CONNECTION + 2 );
...
apr_time_exp_lt(config->time_request_in, apr_time_now());
- in an post_read_request handler I record the time_request_in_end:
apr_time_exp_lt(config->time_request_in_end, apr_time_now());
- i format these values and store in the request_rec->notes;
- in the log phase I record them in a file
At a very high load (450 req/s) I have some entries that have
time_request_in_end greater than time_request_in. This is not normal and cannot
be reproduced at lower loads (50 req/s).
Did anyone encountered this issue? Maybe I am doing something wrong?
Your help is appreciated.
Thanks,
Alin
