httpd fastcgi timeout during transfer

[Chris Narkiewicz]

Hi,

I have a httpd serving PHP app via FastCGI interface.
This application sends quite large data (1GB) but httpd
timeouts the connection during transfer.

What I found is the following sequence of events:

1) curl https://somehost/download/stuff
2) transfer starts
3) no mention of new conncetion in access.log and error.log
   or stdout/stderr
4) 50-60s last I can see GET request in access.log
5) 60s later connection timeout event occurs
6) curl fails

I tried to trace the source of this issue but I'm not
familiar with httpd code. This is the only place where
timeout is set in fastcgi:

/usr.sbin/httpd/server_fcgi.c:369

bufferevent_settimeout(clt->clt_srvbev,
srv_conf->timeout.tv_sec, srv_conf->timeout.tv_sec);
bufferevent_enable(clt->clt_srvbev, EV_READ|EV_WRITE);
if (clt->clt_toread != 0) {
server_read_httpcontent(clt->clt_bev, clt);
bufferevent_enable(clt->clt_bev, EV_READ);
} else {
bufferevent_disable(clt->clt_bev, EV_READ);
fcgi_add_stdin(clt, NULL);
}

Nothing too suspicious here, but I can't figure out
why it timeouts despite data being actively pumped
through the connection?

Any suggestions welcome. I'm out of ideas.

Cheers,
Chris

MacbookAir7,2 (early-2015) -current SUCCESS + dmesg

[Jan Vlach]

Hi openbsd-misc,

I'd like to report install of -current on MacbookAir7,2 (early-2015),
everything works apart from Broadcom wifi (linux sees it as BCM4360 and
ubuntu-based distros have driver/firmware in non-free repo).

- control of display brightness works via xbacklight and I've setup hotkeys in 
i3
  to increase and decreate the brightness by 5%
- keyboard backlight is setup via wsconsctl keyboard.backlight
- APM throttles the CPU at 500MHz-1601MHz
- booting from encrypted softraid, EFI boot partition needs to be set up 
manually,
  partitioning could be MBR and BOOTX64.EFI needs to be copied manually
too.  
- machine runs slightly hot, but fan is silent (at idle)
- using apple USB 100Mbit ethernet adapter, planning on getting ASUS
  nano N10 USB Wi-Fi dongle  later.
- zzz works, using hotplugd to reinitialize network on wake
- changed sd0 serial and MAC address in dmesg down below.

Big thanks!
JV

It was changed from 63 in 2010.

What are you trying to optimize with this?  FFS2 file systems reserve
64 kB at the start of a partition, and after that it's filesystem
blocks, which are 16/32/64 kB, depending on the size of the filesystem.
I can barely see an argument for aligning large partitions at 128
sectors, but what purpose would larger multiples serve?

> Is there a down side  to moving the default offset to 2048 ?

Not really.  It wastes a bit of space, but that is rather insignificant
for today's disk sizes.

Okay, so it sounds like the recommended solution is to use either:
a. synaptics(4) with ClickPad and soft-buttons or tapping, or
b. use wsmouse(4)

Did I understand that right? How do people produce right- or 
middle-clicks with a) and tapping? (for trackpads that have no defined 
soft-button areas)


And to configure b), I assume that's just another set of xorg.conf 
configuration lines? or is there additional complexity I'm missing?



As to the default driver in wsmouse(4), it doesn't require any manual
configuration for clickpads, if you you are happy with soft-buttons (tapping
can be enabled).


That sounds good. But unlike some laptops, my clickpad doesn't have any 
defined soft-button areas. Maybe there is a way to define them?

default Offset to 1MB boundaries for improved SSD (and Raid Virtual Disk) partition alignment

[Tom Smyth]

Hello,

just installing todays snapshot and the default offset on amd64 is 64,
 (as it has been for as long as I can remember)
Is it worth while updating the defaults so that OpenBSD partition
layout will be optimal for SSD or other Virtualized RAID environments
with 1MB  Chunks,

Is there a down side  to moving the default offset to 2048 ?1MB
off set on 512 byte format disks.
we have been running 2048 offset as our starting offset,  for our
OpenBSD  installs for about 3 -4 years now and we have not come across
issues.

it is unlikely that this will be changed in 6.9  release but It might
be worth re-visiting as it would
make for more straightforward  aligned partitions on OpenBSD installs..

my experience is more for x86 / amd64   rather than other platforms ..

Kindest Regards,

Tom Smyth

Re: How to split (A/B) test landing pages using httpd(8)

It might be a cleaner implementation if you use relayd(8) to load balance 
requests, there's also relayctl(8) which you could use to gather diagnostics, 
etc.

Personally, I have never attempted this with httpd alone.
