Re: danf: curl/lib http.c, 1.373, 1.374 http.h, 1.36, 1.37 transfer.c, 1.396, 1.397

Hi Dan,

You might have already oticed. But just in case...

With the factorization of Curl_copy_header_value it is also called in
transfer.c line #933 previous and outside of the '#ifndef
CURL_DISABLE_HTTP' in line #944. While in http.c the prototype falls
inside '#ifndef CURL_DISABLE_HTTP', as well as the implementation in
http.c.

Cheers,

Thanks for letting me know--I hadn't noticed the build logs. I've just
checked in a fix.

GET image after POST

I'm currently trying to write a program in C utilizing libcurl.

I'm using the Tamper Data and LiveHTTPheaders add-ons in firefox to see 
the HTTP headers being traded between my computer and a server. There is 
an initial GET to retrieve the cookies and PHPSESSID.

Next I POST with the desired form values which I retrieve from user 
input. Right after this POST I need to GET an image/gif file. The img 
src is located in the POST form and I don't know how to retrieve it and 
issue a GET at that URL. Firefox does this sequence automatically but I 
don't know how to program. Regexp and string searching is horrible in C 
so I'm trying to avoid that.

Here's a breakdown of what I have so far:

Issue a GET  <at>  URL: get cookies
Issue a POST: send needed form values
(Firefox issues a GET here at the URL within the next POST form, this is 
what I need)
------------------------------------------------------------------------

This is what the POST form looks like:
<form method=post action="http://siteaddress.com/web_message" 
name="challengeForm" onsubmit="return validate(this);">
<table style="margin-left: 75px;" border=1 cellpadding=0 cellspacing=0 
height=55 width=300 bgcolor=#CCCCCC
background="http://siteaddress.com/images/background.gif"><tr>
<td><img height=55 width=300 
src="http://siteaddress.com/unprot-bin/web_message.cgi?image=yes&fkey=~1217596520.8727.1422187.0&ServiceID=0119"></td>
</tr></table>
<p class=body style="margin-top:10px">
<table><tr valign=center><td valign=center class=body-bold>Enter Code 
Above:</td>
<td valign=center><input autocomplete="off" type=text name=chresp></td>
<td valign=center><input type=image
value="Submit" src="http://siteaddress.com/images/submit_button.gif"><input
type=hidden name=fkey value="~1217596520.8727.1422187.0"><input 
type=hidden name=ServiceID value="0119"></td>
</tr></table>
</p>
</form>

How does firefox automatically issue a GET for

http://siteaddress.com/unprot-bin/web_message.cgi?image=yes&fkey=~1217596520.8727.1422187.0&ServiceID=0119 
?
I tried using CURLOPT_FOLLOWLOCATION with no success. I just need the 
value of fkey from the above and then issue a GET at URL 
http://siteaddress.com/unprot-bin/web_message.cgi?image=yes%fkey=[FKEY 
VALUE]&ServiceID=0119

That's my logic so far.

I'm going to do this a bit later, I've been too busy today. However
I've got some news:

- I have rebooted the computer in question and released some allocated
memory and swap in the process. This has made more memory available
for the system, and the installed gm4 is now able to go through
without running out of memory. It appears to be eating up about 100MB
each time it goes through. Before the reboot it would exhaust the
available memory a bit before it got to that point (according to
vmstat). (The system has 512MB RAM).

- Which means that the upcoming autobuilds should go through, at least
over the weekend.

- There was still apparently lots of swap space available even before
the reboot, that didn't seem to avoid the resource problem though -
Solaris may be behaving a bit funny in these cases I assume.

- When I do more testing later on the memory usage by installing a
self-built gm4 on the Solaris computer-

- This probably wouldn't have failed on the x86-64 machine you
mentioned, even if the generic gm4 1.4.5 is buggy, as that machine has
16GB RAM installed.. plus 16GB swap.

Er, that got messed up.. I meant to say that I'll do more testing at a
later time, starting with a self-compiled gm4 1.4.5 on the Solaris
computer, and checking the memory usage compared to the blastwave
version and other gm4 versions as well.

Firefox has a builtin HTML parser :)

libcurl won't help you with that.  Either you're going to have to use
an HTML parsing library or use regular expressions or string matching.

There are many XML parsing libraries around.  Maybe one of them will work.

Aha!. It had to be something. At least now there is a real bone to chew at.

Memory manager returning no memory available to perl or gm4 while it
swaps out and obviously program not retrying on memory allocation
failure ???

If it is an OS or OS configuration issue, the blastwave version should
be the best one as it is supposed to be Solaris specific and might
'know' its internals. But don't leave the perl binary out of the
equation, it might be the real culprit, after all aclocal is a perl
script which executes autom4te which is another perl script which in
turn executes m4.

At least now we're on the right track.
