[Bug 23416] New: PAF5 help content panel is blank for most chapters.

http://bugs.winehq.org/show_bug.cgi?id=23416

Summary: PAF5 help content panel is blank for most chapters.
           Product: Wine
           Version: 1.2-rc5
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

This is a regression in a downloadable application.  I'm sorry, but I cannot
afford the hours of time it takes to run a regression test to pinpoint the
commit that introduced the problem.

With Wine 1.2-rc4, the help window worked fine.  With 1.2-rc5, in the help
window brought up by the yellow question mark, the right-hand content pane is
blank for most chapters.  To duplicate, install and start PAF5, click on the
yellow question mark icon in the toolbar, then observe the right-hand panel is
blank.

The observed symptoms are very similar to a regression introduced in about
1.1.12 and fixed in 1.1.28.

Oh, now I found it.  The bug with similar symptoms introduced in about 1.1.12
and fixed in 1.1.28 is bug #17227.

Ok, I am not seeing the steps to resolve the %20 back into spaces.

Could i get  +relay as well so I can see the steps between shlwapi and the
CreateFile call.

It could be the CreateFile can accept %20 as spaces, so that should be tested.

Please try this patch. shlwapi is improperly flipping the slashes,  not sure if
that is affecting much or not. But it is an error.

Ok, I have had a few moments to use the downloadable applications to attempt
this.

It appears to be a urlmon issue actually. I notice that if i use native
shlwapi, things do not improve.  But if i used native urlmon then i start
getting help pages rendering.

I will look to see if i can find out what is failing in urlmon.dll

Is there anything that can be done to try to get this fixed in the impending
1.2 release?  PAF5's help function was non-functional on 1.0 due to a similar
regression.  Now, it looks like 1.2 will also be non-functional.

I wonder how many years it will be until 1.4, and whether 1.4 might not also
have a similar regression.

I am been working with a new intern here to debug this issue and try to find
what is going on.

It is becoming clear that the issue is pretty deeply connected with wine's
urlmon and the fix is going to require overhauling how urlmon does
CreateURLMoniker or how the resulting moniker handles the
IInternetProtocolRoot::Start method.

I doubt a proper fix will be even an option for 1.2.  There are a few places
that a hack could be put in to correct the behavior but i doubt even more that
that would make it into 1.2

Apparently the same problem for LDS Scriptures 1.1.  Under Help -> Contents,
then Tutorials -> Reference levels, the page does not show.  Other pages show
only a box with a red dot in it instead of the intended content.  Wine 1.2-rc4
works fine.  1.2 and 1.3.0 fail.

With Wine version 1.3.4 and PAF 5, the problem symptoms appear to be gone.

With Wine version 1.3.4 and LDS Scriptures 1.1, the problem symptoms are
greatly reduced, apparently showing essentially all the text of the help pages
but not the graphics.

Was the a fix committed for 1.3.4 that can account for the disappearance of
(most of) the symptoms?

Are other applications still showing symptoms, or are they fixed, too?

I've just added this as a bug Mozart 10.0.9.0 experiences.

With Wine 1.3.4 the Chm help file text renders, but graphics don't and
the links are dead.

Is this bug related to bug 23622 ??

Wine Wine 1.3.5 (didn't check in 1.3.4) the help functions of LDS Scriptures
1.1 have similar behavior reported for some other applications in 1.3.4 and
1.3.5.  Most of the text renders well, but the graphics don't.  Some of the
text pages don't render--showing no change in the right-hand content pane when
a new topic is clicked in the left-hand TOC pane.

With wine-1.3.5, Mozart 10.0.9.0 still displays the bug.  Text renders, but
graphics do not render. Links in the help text to other parts of the help file
are dead.  This makes the Mozart help largely unusable from within WINE and
requires a third party viewer such as kchmviewer to display the information.
With the third party viewers, the *.chm files render as they should.

This is not my result with the Mozart software.
Here, with a clean install of the January 7, 2011 wine-1.3.11
release, the Bug is alive and well.

Is wine-1.3.11-284-ge98a0e5 the current git as of 2011-01-17 11:43:48 CST ?

Should we look forward to this as a bugfix in the next release?

As of wine-1.3.12, the Bug as stated,"...help content panel is
blank for most chapters," is no longer present in Mozart 10.

Using  wine-1.3.12, the Help contents do indeed display as text,
but without image rendering and without the ability to follow
links in the text. Javascript popups such as"javascript:mzpopup(..."
are also not rendered.
> From my point of view, this is excellent progress. Since this

bug, 23416, as stated is fixed, should a new one be started
for these other issues, or is there another bug report covering
those problems?

With Wine 1.3.12, application PAF5 does display text.  However, the application
crashes after clicking on four chapter titles.  I filed a new bug #25873 for
that new symptom.

I'm not able to tell whether the root cause of this bug is the same as or
different from that of #25873, so I don't know whether this one should or
should not be marked fixed.  The symptoms have varied for this one, so it
_might_ be the same root cause.

I'm as puzzled about where the problem begins as you are.  In the App
I maintain, "Mozart," the author has placed the help system in *.chm, aka
"Compiled HTML" files.  A third party chm viewer renders these fairly well.

I've noticed that a wine program that comes with the release, "hh.exe,"
gives the same rendering as the help window that opens when accessing help
from Mozart.  I.E., no images, no active links, etc.  But I don't know if
this is what is being used when runing an app, and therefore is a logical
place to look, or if the rendering takes place elsewhere. I could also start
bugs for the various bits I've noticed, but it does seem like an un-necessary
proliferation if all this stems from the same point.

Also,

Because of the age of the reports (2008) I doubt that they can be
directly related to present code, but both the link reference and 
accessing help causing a program crash have been addressed before.

Both were closed, but might have a clue.

Also, the symptoms appear to have gone away with Wine 1.3.16 and Wine Gecko
1.2.0 and application LDS Scriptures 1.1.

Excellent!

With wine-1.3.16 and the new Gecko, both the Mozart help and
the Mozart tutorial show no signs of this bug.  Also, the
images render and the various links work in this app's *.chm
help and tutorial files.
