Bug ID: 39892 Summary: Regression in Wine 1.7.33+ causes UFile to crash with runtime error when rendering certain pages Product: Wine Version: 1.9.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: anthony@anthonyfok.org Distribution: ---

Created attachment 53271 --> https://bugs.winehq.org/attachment.cgi?id=53271 Winedbg 1.9.0 log of UFile 2013 crashing at the NetFile "Interview" page

UFile 2013, which worked almost flawlessly and successfully submitted my Canadian tax returns over the Internet on my behalf with Wine 1.7.17:

* https://appdb.winehq.org/objectManager.php?sClass=version&iId=30238 (from May 2014)

now crashes consistently with a _CxxThrowException() error at msvcr100 upon clicking on the link to certain "Interview" pages. This has been tested on both Ubuntu 14.04.3 LTS and Debian sid (December 2015) with Wine-1.8 (provided by the distributions) and with Wine-1.9.0 (from WineHQ).

This same problem also plagues the newer UFile 2014, and presumably with UFile 2015.

After many trials to no avail, I finally went back to wine-unstable:i386 (1.7.17-1) from snapshot.debian.org, and... it worked!

Some more tests later, I found that wine-development:i386 (1.7.32-1) was the last good working version. From 1.7.33 on, up to 1.7.55, 1.8 and 1.9.0, Wine would crash when I click on a UFile "Interview" page like "NetFile". The "Interview" pages that crash seem to be the ones that involve some kind of HTML rendering, e.g., where an image or a hyperlink is included in the introductory text.

Just to make sure it has nothing to do with the new GCC 5.x toolchain, I took Debian's old 1.7.32-1 package from December 2014 and recompiled it inside a pbuilder/cowbuilder environment for sid-i386. Both Debian's old 1.7.32-1 package and my recompiled package work flawlessly, while both Debian's old 1.7.33-1 and my recompiled package crash at the same place.

Note, however, that HTML Help dialog works fine with all the above Wine versions up to Wine 1.9.0.

Nevertheless, since the runtime exception seems to have initiated from UFile's own DtHtmlLabelDll.dll, and pages with plain-text introductory text renders fine in Wine 1.7.33 to 1.9.0, I suspect that some changes in MSHTML introduced in 1.7.33 could be the cause of this regression.

Thanks in advance!

Anthony

--- Comment #9 from Anthony Fok anthony@anthonyfok.org --- Sorry, I pressed the wrong key and sent out the last comment prematurely.

It seems that Wine (1.7.33 to Wine-1.9.0) crashes after encountering an "onclick" that looks like the following:

<A href='javascript:void(0);' onclick='showHelpWindow(\"hlp_netfile.htm\");'>click here</a>

<A href='javascript:void(0);' onclick='showHelpWindow(\"hlp_efile_eol.htm\");'>click here</a>

<A href='javascript:void(0);' onclick='showHelpWindow(\"hlp_netfile.htm#xmit\");'>click here</a>

<p> If you do not use NetFile, you must <A href='javascript:void(0);' onclick='showHelpWindow(\"hlp_print.htm\");'>print your tax return</a> and mail it to the government.

These strings are extracted from "C:\Program Files\UFile 2013\UB1X13A.dte".

Does it have freely available demo/full version to test?

Yes, the full version may be downloaded from:

http://downloads.drtax.ca/ufile/UF2013EGYH34U86GA23WHUS4/UFile2013.exe

(The download URL was found in pages like http://support.drtax.ca/KB/faqs-windows-english/source/webpages/kpt240-20140... and http://community.ufile.ca/index.php?/topic/4931-availability-of-downloadable... .)

It can be installed simply by running "wine UFile2013.exe".

However, UFile for Windows requires an activation key before it can be used...

--- Comment #12 from Anthony Fok anthony@anthonyfok.org --- Created attachment 53280 --> https://bugs.winehq.org/attachment.cgi?id=53280 Prevent type mismatch error with getAttribute("onclick", 2)

It appears that UFile tries to do this:

getAttribute("onclick", 2);

However, HTMLElement_get_onclick() somehow gives back an AttributeValue of VT_NULL, which of course fails to be converted to VT_BSTR, thus VariantChangeType() returns a HRESULT of 0x80020005 (Type Mismatch), which HTMLElement_getAttribute() also returns, leading to the runtime error and crash.

In Wine 1.7.32, HTMLElement_getAttribute() did not do any VariantChangeType(), and happily returns S_OK as the HRESULT, so UFile kept on running happily without crashing.

So, the attached patch adds a test case for VT_NULL and change it to a VT_BSTR(NULL) and returns S_OK, reverting to the behaviour in Wine 1.7.32. No more crashing. Yay!

However, I do suspect the real problem lies with HTMLElement_get_onclick() and other JScript-related HTMLElement_get_xxxxxx() functions. Shouldn't it be able to return an AttributeValue as a string (i.e., BSTR)? How did it become VT_NULL?

--- Comment #13 from Anthony Fok anthony@anthonyfok.org --- Created attachment 53285 --> https://bugs.winehq.org/attachment.cgi?id=53285 Add getAttribute("onclick", 2) test to jstest.html

This new test case in the attached mshtml-jstest-getAttribute-onclick-2.patch would trigger the same problem I saw in UFile 2013:

cd ~/wine-dirs/wine-build/dlls/mshtml/tests WINEDEBUG=+mshtml,+variant make script.ok

except that this WineTest hangs after

err:mshtml:update_window_doc GetDocument failed: 00000000

instead of triggering _CxxThrowException() like UFile does.

After applying prevent-0x80020005-type-mismatch-error-with-getAttribute-onclick-2.patch, this particular WineTest gives an error:

script.c:632: Test failed: L"getAttribute('onclick') = "

instead of giving the string value of the onclick attribute, but WineTest continues merrily on.

Hope this helps!

Thank you for the analyse. Does the attached patch help? That's the proper solution for custom attributes. Proper support for event attributes is more tricky to get right, but hopefully this will be enough.

--- Comment #15 from Anthony Fok foka@debian.org --- Hello Jacek,

Thank you for your "A fix for custom attributes" patch! And yes, it works! :-)

Your patch has indeed fixed the regression, and all "Interview" forms in UFile can now be displayed without hiccup or crash, just like it was in Wine 1.7.32. :-)

(Alhough getAttribute("onclick", 2) is not yet able to retrieve onclick's string value, and such JavaScript-based buttons do not yet work, these buttons are only used in the help text and do not affect UFile's overall usability.)

So yes, your patch looks very good to me. Many thanks for your expert help!

Cheers, Anthony
