Bug 59110 – IconDataBase.cpp IconDatabase::iconDatabaseSyncThread() assert Failure

• Status: UNCONFIRMED
• Component: WebCore Misc.

Hi There
This only happens when compiled for Debugging i.e. when the
ASSERT_ICON_SYNC_THREAD(); generates actual code.
It doesn't always fail only sometimes.
Unfortunately gdb is unreliable on our mips system for multiple threads.

I checked out webkit overnight from 20-21 of April the revision on IconDatabase.cpp is 84479.
It may be the m_syncLock.lock(); is uninitialised or not working properly.

Adding the line WTF::Mutex::Mutex(m_syncLock); 
to initialise the m_synclock to the
to IconDatabase::IconDatabase() constructor
in IconDatabase.cpp doesn't fix the problem

ASSERTION FAILED: m_sharable || currentThread() == m_openingThread
/home/djbarrow/jacktest/stbsetup/webkit_build/WebKit-110203/Source/WebCore/platform/sql/SQLiteDatabase.h(106) : sqlite3* WebCore::SQLiteDatabase::sqlite3Handle() const


Also getting this one from looking at it by the same coder.

I'm on a little endian embedded mips platform with a single CPU.

@ap - do we even support MIPS Embedded platform anymore? Do we need to track this? Thanks!

This doesn't seem platform specific. Safari doesn't use WebKit icon database AFAIK, but other posts could be affected.
