2011-09-20Fixed loss of chain links in ngx_event_pipe_read_upstream().Maxim Dounin1-0/+1
2011-09-20Fix of cpu hog in event pipe.Maxim Dounin1-2/+2
If client closed connection in ngx_event_pipe_write_to_downstream(), buffers in the "out" chain were lost. This caused cpu hog if all available buffers were in the "out" chain. Fix is to call ngx_chain_update_chains() before checking return code of output filter to avoid loosing buffers in the "out" chain. Note that this situation (all available buffers in the "out" chain) isn't normal, it should be prevented by busy buffers limit. Though right now it may happen with complex protocols like fastcgi. This should be addressed separately.
2011-09-20The "worker_aio_requests" directive.Igor Sysoev1-3/+13
The default value is 32 AIO simultaneous requests per worker. Previously they were hardcoded to 1024, and it was too large, since Linux allocated them early on io_setup(), but not on request itself. So with default value of /proc/sys/fs/aio-max-nr equal to 65536 only 64 worker processes could be run simultaneously. 32 AIO requests are enough for modern disks even if server runs only 1 worker.
2011-09-19Replaced "can not" with "cannot" and "could not" in a bunch of places.Ruslan Ermilov2-6/+6
Fixed nearby grammar errors.
2011-09-16Fixing Linux AIO initiatialization: AIO operations are disabled if kernelIgor Sysoev1-47/+82
does not support them. Previously worker just exited.
2011-09-16Fixing Linux AIO syscalls return value handling:Igor Sysoev1-10/+11
syscall(2) uses usual libc convention, it returns -1 on error and sets errno. Obsolete _syscall(2) returns negative value of error. Thanks to Hagai Avrahami.
2011-09-15Upstream: pipe length and input_filter_init in buffered mode.Maxim Dounin2-0/+30
As long as ngx_event_pipe() has more data read from upstream than specified in p->length it's passed to input filter even if buffer isn't yet full. This allows to process data with known length without relying on connection close to signal data end. By default p->length is set to -1 in upstream module, i.e. end of data is indicated by connection close. To set it from per-protocol handlers upstream input_filter_init() now called in buffered mode (as well as in unbuffered mode).
2011-09-15API change: ngx_chain_update_chains() now requires pool.Maxim Dounin1-1/+1
The ngx_chain_update_chains() needs pool to free chain links used for buffers with non-matching tags. Providing one helps to reduce memory consumption for long-lived requests.
2011-09-01Proper setting of read->eof in pipe code.Maxim Dounin1-1/+1
Setting read->eof to 0 seems to be just a typo. It appeared in nginx-0.0.1-2003-10-28-18:45:41 import (r164), while identical code in ngx_recv.c introduced in the same import do actually set read->eof to 1. Failure to set read->eof to 1 results in EOF not being generally detectable from connection flags. On the other hand, kqueue won't report any read events on such a connection since we use EV_CLEAR. This resulted in read timeouts if such connection was cached and used for another request.
2011-09-01Proper SSL shutdown handling.Maxim Dounin1-0/+5
If connection has unsent alerts, SSL_shutdown() tries to send them even if SSL_set_shutdown(SSL_RECEIVED_SHUTDOWN|SSL_SENT_SHUTDOWN) was used. This can be prevented by SSL_set_quiet_shutdown(). SSL_set_shutdown() is required nevertheless to preserve session.
2011-08-04A new fix for the case when ssl_session_cache defined, but ssl is notIgor Sysoev2-5/+3
enabled in any server. The previous r1033 does not help when unused zone becomes used after reconfiguration, so it is backed out. The initial thought was to make SSL modules independed from SSL implementation and to keep OpenSSL code dependance as much as in separate files.
