Bug fix for 2827039

Dennis Jenkins — Wed, 18 Aug 2010 21:50:28 -0000

We recently discovered an apparent memory leak in EasySoap. We create and cache a SOAPProxy object and re-use it. Every call to Execute() would leak the parsed XML stream from the previous invocation of Execute(). I tracked this down to the "pool" holding the xml snippets in the SOAPBody in SOAPResponse not being released. All of the memory was properly released when the SOAPProxy was destroyed.

Our bug find is very similar to #2827039, reported on 2009-07-25.

I am attaching a fix against 0.6.0 (we have not updated to 0.8.0 yet). I hope that it serves others well.

Note: Our easysoap is a vendor branch in subversion. The patch is against my own branch, not against any CVS revision hosted on source forge. However, the patch should help anyone else trying to patch 0.8.0. Basically, in SOAPProxy::Execute() you need to invoke "Reset()" on the "body" of the previous "response". There is probably a better solution, but ours seems to work.

ps- is this project being actively maintained anymore?

Fix bug in Deserialising Unsigned Integers

Jamie McNaught — Mon, 11 Oct 2004 23:13:02 -0000

Unsigned integers are deserialised by a call to
sp_strtol which is a which returns a signed interger
(and will overflow with large unsigned integers).

Added the function sp_strtoul (which is an exact copy
of sp_strtol really) and changed the unsigned interger
deserialisation code to call this instead.

Note, I've not given this a great deal of testing.
Infact it may not work at all. And it has only been
tested on Linux (RH9).

SOAPWinInetTransport, allows access to InternetSetOption()

Dennis Jenkins — Sat, 29 May 2004 16:45:42 -0000

This patch adds two methods to the SOAPWinInetTransport
class:

bool InternetSetOption\(int nHandle, DWORD dwOption,

void *pBuffer, DWORD dwBufferLen);
bool InternetQueryOption(int nHandle, DWORD dwOption,
void *pBuffer, DWORD *pdwBufferLen);

These are almost pure wrappers around the WinInet
functions of the same name. However, the "HINTERNET"
handles in the class are private, so that caller
specifies which handle they want by passing an
'nHandle' value of 0-3. 0 = NULL, 1 = m_hInternet, 2 =
m_hConnect, 3 = m_hRequest. Anything else is an error.

Please feel free to rewrite this code. I added it
because I need to set a status call back using the
options: INTERNET_OPTION_CALLBACK and
INTERNET_OPTION_CONTEXT_VALUE. For more information,
consult
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wininet/wininet/option_flags.asp

Please let me know if/when this patch (or something
like it) is merged into CVS. Thank you very much.

I release any copyright/whatever to the original author
of this package and the rest of the world. yadda yadda
yadda.

Thanks for such a great C++ soap client.

gzip support + error codes

Tue, 25 May 2004 18:09:58 -0000

There are patches together. sorry for that.
* Made gzip support optional (defining HAVE_LIBZ will
enable it otherwise it will be disabled)
* Updated buildconf.sh script
* Updated configure.in scirpt (so that gzip can be
enabled with "--with-zlib" option)
* Added support for SOPAExceptions to return not only
description but also error code, so it is easier to
identify errors

that's all ;)

Updated 917561 patch (gzip support)

Mon, 24 May 2004 18:13:18 -0000

SOAP payload decompression using zlib with correct gzip
support. Actualy its updated 917561 patch. Diff with
CVS (24.05.2004).

SOAP payload decompression using zlib

Sandro Tolaini — Tue, 16 Mar 2004 20:01:12 -0000

This patch allow easysoap to understand and
decompress compressed XML payloads. Need zlib.

fix XMLParser explicit casts

Aivars Kalvans — Wed, 04 Feb 2004 21:21:06 -0000

This patch will fix bug#702998 (I had the same problem
when compiled EasySoap++ on HP-UX).

Close WinInet handles as soon as possible

Sandro Tolaini — Tue, 14 Oct 2003 09:59:05 -0000

When using WinInet transport, EasySOAP doesn't close
the request handle until a new request is made. WinInet
library has a limit of 2 handles that can be keep opened
simultaneously, every new handle request will be
delayed until another handle is closed. This is very bad
when you create more than 2 SOAPProxy objects: after
the first two have done a call, the other proxy objects
will not be able to create a request handle.

This patch closes the request handle as soon as
possible (i.e. after reading the reply payload).

The patch also fixes a problem with empty SOAPAction
header (another patch was floating around for this).

Please apply the patch before next release!

Set array item name

Anonymous — Mon, 03 Feb 2003 21:27:49 -0000

This patch allows you to set the name attribute of the
items in an array. It adds a static string "itemName"
which is set to the compatible string "item", which
emulates the existing behaviour. Calling
SOAPArrayTypeTraits::setElementName("foo") will change
the name of all subsequent created array items to
"foo". setElementName returns a string of the previous
elementName.
