asmXPTC_InvokeByIndex Bogus Return Value in WinMobile builds


(Core :: XPCOM, defect, critical)

Windows CE
Not set

When calling XPTC_InvokeByIndex on WinMobile builds, the return value of the function is a random, bogus value.

The function prototype for XPTC_InvokeByIndex is:

extern "C" nsresult
asmXPTC_InvokeByIndex( nsISupports* that,
                       PRUint32 methodIndex,
                       PRUint32 paramCount,
                       nsXPTCVariant* params,
                       PRUint32 pfn_CopyToStack,
                       PRUint32 pfn_CountWords);  

This nsresult random return value will mess up anyone who is examining the function's return code.  

All arguments passed into the function appear to be handled correctly.

Patch for this bug will also update the XPCOM/Proxy/Tests to check for this (and other) potential error.
Attached patch WinCE XPCOM Patch (obsolete) — Splinter Review
Revises XPCOM/proxy/tests to be more complete, fixes asmXPTC_InvokeByIndex return code
Assignee: nobody → wolfe
This is a revised patch for the WinCE XPCOM return code value being incorrect.

This patch adds more duplicate output via printf and LOG(), allowing a casual tester to see immediate feedback about the XPCOM proxy functionality.

Attached patch Oops - Added a needed IDL file (obsolete) — Splinter Review
HG does not take added files unless you actually do an "hg add" -- my oops.

Here is the revised patch file, which should compile XPCOM/proxy/tests executables correctly.
Attachment #323132 - Attachment is obsolete: true
I pulled out the large Proxy Test class into its own file - then end up including that CPP file back into proxytests.cpp because of automated build Makefile struggles.  This latest patch has all files added into the mix - with the result compiling the <OBJDIR>/XPCOM/proxy/tests directory.

Just removed two unnecessary commented out lines of assembly code which would have cluttered up the ASM file.  As per request of DougT

Same as Benjamin's reviewed file, but with different indentation for, and removed mozce_shunt_static.vcproj and nsProxyEvent.cpp file changes.

The mozce_shunt_static.vcproj file change and the nsProxyEvent.cpp file change should not have been included in the patch to be reviewed. 

Thanks to Benjamin for catching those un-needed patch hunks!

This was backed out due to build failures.  The Makefile was broken (trailing spaces after some \'s, missing $(NULL) in XPIDLSRCS), and a header file was missing.

Could you post a fixed patch please?

Fixed patch file, including bugs listed and missing header/source files.

Sent back to Benjamin for re-review.  Nothing new in this patch, just missing files and fixes (I have no idea why/where the previous patch came from in my compiling system).

You want to request review from ":bs" (or benjamin@smedbergs) instead of that address (he only uses it for watching).

Attached patch v.8 patch (obsolete) — Splinter Review
Same as Attachment 337352 [details] [diff], but adjusts UUIDs so each are unique in XPCOM Proxy Tests.

Not for review yet, want to make sure this does not mess up the Win32 build.

Also, for some reason, GetProxyForObject is returning NULL proxy objects under WinMobile 6 XPCOM Proxy Test (running on HTC Touch Diamond USA).

just so it is obvious what I am doing - the patch is the same as what was review by bsmedberg.  wolfe updated it and changed the uuids as requested.  I looked over it, applied it to my build and it works on windows ce and win 32.
