I do hope (and feel) they are interested in helping to make this work and fix potential problems in the Synapse code. This is why I upgraded to the most recent svn sources of Synapse (and found that it obviously is not yet tested on ARM: it does not compiled without a (simple) modification). Here are my latest finding: - I set the ConnectTimeout property and I set the other timeouts by calling SetTimeout. - As described my project does perform two complete HTTP communications with the target successfully. - With the third access, the connect does work even without a timeout and a retry performed by my software (Synapse Status log: 7 = HR_CanWrite / 5 = HR_Connect). - then it does 11 = HR_WriteCount is shown, supposedly indicating my write request. and 13 = HR_Error seems shows that a timeout error on that Write occurred. - my latest log shows that the timeout occurs after more than 15 Minutes (see below). - my software does a retry and the same happens again. Now the extended Timeout is one problem, but the primary problem is why this write HTTP access does not work, while the previous two accesses do work fine. How do we proceed ?

Re: [fpc-devel] Synapse hangs in ARM-Linux
Follow-up: I d/l'ed the most recent Synapse snapshot and when compiling I get: Compiling ./synapse/synautil.pas jedi.inc(512,4) Error: Illegal assembler style specified INTEL This is easily fixed by commenting out the appropriate line in jedi.inc, but it shows that this Synapse version is not yet tested on ARM. Now I set the ConnectTimeout to 1 (10 seconds) and retested. I found that in fact Synapse does return to the user program which requests a retry but in one test of the same project it finished after about 30 Minutes and in another it was after more than 60 (I killed the test after that time.) . Either some other Timeout definition is used, or the timeout in that case does not work decently I found that with Synapse on Windows and PC Linux, the Target (Heating Controller device) mostly seems to force a timeout (or some other error resulting in a retry) but sometimes not. With 20 or more seconds connect timeout I usually get one retry, with 10 Seconds connect Timeout I usually get two retries. But on ARM the project always hangs on the third HTTP request (after two successful ones.) I did do some logging using HTTPSend.Sock.OnStatus. (complete Logs below) Here in Windows I see a: 13:10060,Connection timed out after 30 Seconds (I think I did set the ConnectTimeout to 3 at this time) resulting in a retry requested by my software. Note that the timeout comes after 2:IPv4 (2 being HR_SocketCreate if I am not failed, and 7 = HR_CanWrite / 5 = HR_Connect are not reached on the first try.) The Log for the ARM version shows something very different (unfortunately this version of my software did not yet timestamp the log. I'll retest with the updated version ASAP.) 2:IPv4 7: 5:192.168.71.252:80 11:5382 13:110,Connection timed out Seemingly the connect ( 7 = HR_CanWrite / 5 = HR_Connect) is performed without a timeout being hit. Now it does 11 = HR_WriteCount is shown, supposedly indicating my write request. and 13 = HR_Error seems shows that a timeout error on that Write occurred. Seemingly the target does not understand or like the write request issued by synapse. Seemingly this is deterministic and happens all the time. Is the number given with the 11 = HR_WriteCount log message indeed the count of bytes that are written in this request or is it an accumulated count ? In fact I think I issue not more than 100 bytes per request. Any additional suggestions ?

Re: [fpc-devel] Synapse hangs in ARM-Linux
In fact I feel that no Route is the more appropriate Error message. When trying to access a not known local IP, the system should issue an ARP request that will time out much faster than the Connect Timeout. After this a no Route Error should be generated by the system. -Michael ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

i'm trying to make sure i'm following along here because i'm also using synapse
for a project...
using a slightly modified testhttp (that came with synapse, attached) and
attempting to connect via http to a non-existant IP in my network, i get a 0
result code, empty result string and Connection reset by peer string on my
winwhatever box but that may be due to a firewall proxy that is injected into
all http streams on that winwhatever system... on my os/2 eCS2 box, i get 500
result code, empty result string and Connection refused string... however, if
i try using a non-existent hostname, both return 500 result code, empty result
string and Host not found string...
i would suggest that trying to use a non-existent IP or host is not the way you
want to go to test this... the results are not going to be what you should be
getting from the heating controller connection when it fails...
your No route to host actually sounds plausible if there is, in fact, no route
to the IP you have chosen... that also sounds like there's no default routing
gateway defined for networking traffic headed out of the local network... when i
test trying to access a non-existent IP outside my local network, my winwhatever
box reports Connection reset by peer (as above) and my OS/2 eCS2 box reports
Connection timed out...
suffice it to say that synapse's error codes are not always they seem to be,
unfortunately... run testhttp and you'll see what i mean... i'm pretty sure
there are other result codes and strings that i've not been told about or
discovered yet... oh, and yes, this testhttp will use ssl libraries if they
exist so you can test against https as well as http ;)
