304906 - NS_InitXPCOM2 (and friends) should arrange that the specified xpcom directory is in the path

Status: RESOLVED WONTFIX

(Core :: XPCOM, defect)

Description

[timeless]

we have a module which runs from bin\, it is loaded by an app ..\foo\bar.exe

our module calls xpcom_core.dll!NS_InitXPCOM2_P and specifies the bin directory
as where xpcom is. XPCOM proceeds to initialize.... at first xpc3250.dll fails
to init because js3250.dll can't be found. we claim and dougt accepts that when
we told xpcom to init with the bin\ directory as its starting point that it
should use that as part of its path. The only real symptom is a dialog
complaining js3250.dll because eventually xpc3250 and js3250 actually load.

from NS_InitXPCOM2_P:
+       
{,,xpcom_core.dll}((*(nsACString*)(&(*(nsCSubstring*)(&(*(nsLocalFile*){*}binDirectory).mWorkingPath))))).mData
       0x02d63400 "C:\Program Files\Vendor\Vendor Product\Engine\BackEnd"      
 char *

from nsNativeComponentLoader::GetFactory:

+       
{,,xpcom_core.dll}((*(nsACString*)(&(*(nsCSubstring*)(&(*(nsLocalFile*){*}(((*(nsCOMPtr_base*)(&(*dll).m_dllSpec))).mRawPtr)).mWorkingPath))))).mData
       0x02d98dc0 "C:\Program Files\Vendor\Vendor
Product\Engine\BackEnd\components\xpc3250.dll"        char *

        if (!dll->Load()) {
fell into the ! case (Load returned 0)
because of js3250.dll
