I pulled Friday's last-known-good Apprunner (MOZ_CO_DATE="09/03/1999 14:59:32 PDT") and compiled it on FreeBSD 3.2-RELEASE with egcs 1.1.2, and it crashes on startup.

The FreeBSD tinderbox on the ports page is also orange, I'd guess it's the same problem. I've added briano as a Cc: since he's the port owner...can you see if it's the same problem I was reporting here?

I've reopened this, since I'm seeing the same symptoms with today's build. I think FreeBSD 3.2-RELEASE and 4.0-CURRENT are behaving differently here. (I've changed the bug's summary line accordingly.) After a bit more investigation, it looks like this is actually three different crashes, and one case where Apprunner will start correctly. Crash 1: initial start, ~/.mozilla doesn't exist, mozilla/dist/bin/component.reg doesn't exist: (gdb) run Starting program: /local/llennox/Mozilla/mozilla/dist/bin/./apprunner nsNativeComponentLoader: autoregistering /local/llennox/Mozilla/mozilla/dist/bin/components Program received signal SIGBUS, Bus error.

I think this crash is what is turning the FreeBSD tinderbox orange. Next: immediately re-run, after previous crash: *success*. A whole bunch of components register, and then the profile wizard pops up; once a profile has been created, apprunner runs happily. Crash #2: quit apprunner, and restart it. we get the crash I described in the original bug report. This is now a steady state, crashing every time, unless files are deleted manually. Crash #3: delete component.reg, but *not* ~/.mozilla. In this case, we crash shortly after the "Calling gdk_input_add with event queue" debug message is printed: (gdb) down 15 #0 0x28baf5a5 in nsUnicharStreamLoader::OnDataAvailable (this=0x8407d60, channel=0x840c200, ctxt=0x0, inStr=0x0, sourceOffset=0, count=32768) at nsNetStreamLoader.cpp:175 175 inStr->GetLength(&len); (gdb) print inStr $1 = (nsIInputStream *) 0x0 (gdb) bt #0 0x28baf5a5 in nsUnicharStreamLoader::OnDataAvailable (this=0x8407d60, channel=0x840c200, ctxt=0x0, inStr=0x0, sourceOffset=0, count=32768) at nsNetStreamLoader.cpp:175 #1 0x2937105c in nsChannelListener::OnDataAvailable (this=0x83f5c90, aChannel=0x840c200, aContext=0x0, aInStream=0x0, aOffset=0, aCount=32768) at nsDocLoader.cpp:2476 #2 0x294a2d2c in nsFileChannel::OnDataAvailable (this=0x840c200, channel=0x840c200, context=0x0, aIStream=0x0, aSourceOffset=0, aLength=32768) at nsFileChannel.cpp:807 #3 0x29737a2b in nsOnDataAvailableEvent::HandleEvent (this=0x82f1040) at nsAsyncStreamListener.cpp:344 #4 0x2973727f in nsStreamListenerEvent::HandlePLEvent (aEvent=0x82f1040) at nsAsyncStreamListener.cpp:144 So we have three separate crashes, none of which occur on FreeBSD 4.0-CURRENT. My suspicion is that this has something to do with DSO loading, and that bug 6323 is related, since it similarly has the symptom of not occuring on FreeBSD 4.0-CURRENT (or Linux), and seems to have something to do with the shared libraries. Are there any other FreeBSD 3.x people out there?

I'm checking in a fix that ought to resolve the following crash: #0 0x281a8de6 in nsDll::Load (this=0x805aa80) at xcDll.cpp:260 #1 0x281a24bd in nsNativeComponentLoader::GetFactory (this=0x80512e0, aCID=@0x80718e0, aLocation=0x806d540 "rel:libucvko.so", aType=0x8071900 "application/x-mozilla-native", _retval=0xbfbfccd0) at nsNativeComponentLoader.cpp:121 #2 0x281d3b8e in nsFactoryEntry::GetFactory (this=0x80718e0, aFactory=0xbfbfccd0) at nsComponentManager.h:297 #3 0x2819f875 in nsComponentManagerImpl::FindFactory (this=0x805a100, aClass=@0x812fd80, aFactory=0xbfbfccd0) at nsComponentManager.cpp:1027 #4 0x2819fd9e in nsComponentManagerImpl::CreateInstance (this=0x805a100, aClass=@0x812fd80, aDelegate=0x0, aIID=@0x281da980, aResult=0xbfbfcd7c) at nsComponentManager.cpp:1198 It still crashes for me, but I'll keep on it.

As of the 1999-09-13 morning build, the nsDll::Load crash is gone, but I'm still seeing the nsIDKey::nsIDKey and the nsUnicharStreamLoader::OnDataAvailable crashes. Also, the case which got a working apprunner before (second run after deleting component.reg and ~/.mozilla) no longer does; I always see the nsIDKey crash if component.reg doesn't exist, or nsUnicharStreamLoader if it does.

Comment 9•25 years ago

Okay, I've gotten a diagnosis of what's going on in the first crash -- the nsIDKey crash -- and it's a sufficiently insidious problem that I suspect if it's fairly general it could be the cause of all the other startup crashes, and the PNG/JPEG problems, as well. See the gdb log I've included as an attachment (right after this comment). Notice that the components being registered for all the Unicode converters all have names involving Japanese character sets, even for libucvcn.so and libucvlatin.so (which should be Chinese and European respectively). The problem is occuring because the symbol g_FactoryData exists in all the uconv libraries; for some reason, RegisterSelf in libucvcn and libucvlatin is picking up the g_FactoryData definition from libucvja. The crash, specifically, is occuring because the size of the array is computed at compile time, and g_FactoryData is longer in nsUCvLatinDll.cpp than in nsUCvJADll.cpp, so libucvlatin.so's RegisterSelf is walking off the end of the (wrong) array and catching a SIGBUS. Symbol names are repeated between enough different components that if this bug is "symbols are resolved to the first symbol loaded with that name, rather than the one in this DSO," it will wreak havoc on Mozilla -- as indeed seems to be happening. Does this help anyone enough so as to track down what might be going wrong? I wish I knew when precisely this bug was introduced.

frank/dp, can you comment on this bug?
Comment 13•25 years ago
|

Please try the following and let me know does it help: 1. Change all the *Dll.cpp in mozilla/intl/uconv/ucv* 2. change the line FontFactory g_FactoryData[]= to static FontFactory g_FactoryData[]= rebuild intl/uconv/
Reporter | ||
Comment 14•25 years ago
|
||
Yep, that clears up the nsIDKey / uconv crash, and a gdb trace shows that the uconv libraries are registering properly. I now crash in nsUnicharStreamLoader::OnDataAvailable, as above. Still, it seems very strange to me that FreeBSD should have this problem, when none of the other platforms do; it implies to me that there's something wrong with components on FreeBSD. Non-exported symbols are supposed to be component-local, right?
Comment 15•25 years ago

bug 13030 could realted to this. add braino@netscape.com to the CC. Could you do a nm ucvlatin.so|egrep g_FactoryData in the build that you didn't put the static ? What do you see ? My linux build show nothing but I guess you will see something there... I will add static to all the *Dll.cpp But I think the problem have to be fixed in the configuration file. Braino, any clue ?
Reporter | ||
Comment 16•25 years ago
|

bash-2.02$ nm libucvlatin.so|egrep g_FactoryData 0002d4e0 D g_FactoryData The 'static' patch changes the 'D' to 'd', i.e. the symbol isn't extern any more. It really doesn't show up in 'nm' at all on Linux? g_InstanceCount, g_LockCount, and g_ASCIIMapping are similarly defined in multiple uconv components, but I got error messages when I tried to declare those static.
Reporter | ||
Comment 17•25 years ago
|
||
Just discovered: configuring with --enable-low-fat also cures the nsIDKey / uconv crash, since it uses gnu ld tricks to mark all symbols unexported. (This has nasty side effects though, namely spewing "Ignored d_tag " messages. I'll file another bug report on this.) After this, I can get apprunner to start, *if* (this one mystifies me) I run under gdb, and set a breakpoint at dlopen(). The breakpoint never triggers, but somehow this avoids the onDataAvailable crash... Apprunner looks *very* different when compiled this way, too -- it's like night and day. Before, gfx textboxes were mangled, the sidebar wasn't working...I hadn't realized how functional Mozilla was by now.
Comment 18•25 years ago
|
||
I checkin the change to make all g_FactoryData as static. But it should not be the real problem. Right. No nm display nothing to me if I type bash-2.02$ nm libucvlatin.so|egrep g_FactoryData 0002d4e0 D g_FactoryData Not even with D. No you cannot make other symbol static since they are not true file private. This g_FactoryData is true file private. Should we consider this bug closed ?

No, the component issues and the other crashes are still open. I think the i18n part of it is resolved, though.

Is that true this is a compiling/build configuration issue instead of a component issue ?
