[Bug libgcj/25593] Socket problems
--- Comment #1 from ovidr at users dot sourceforge dot net 2005-12-28 23:24 --- Created an attachment (id=10562) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=10562&action=view) Testcase (HServer.java and HClient.java) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25593
[Bug libgcj/25593] New: Socket problems
When using jcraft's jsch ssh2 port forwarding in a gcj compiled application,
connections terminate unexpectedly. It works fine in Sun's java.
I've tried to make a test case with HServer/HClient. The server listens to a
port, and then the client connects to it. The OutputStream is closed while the
InputStream is still reading in another thread.

[Bug libgcj/18266] SIGSEGV in GC_register_finalizer_inner ()
--- Additional Comments From ovidr at users dot sourceforge dot net
2005-07-19 15:06 ---
I've spent a lot of time trying to make a testcase of this, but no luck yet.
I can basically create a testapp with 2 threads. When they both access a
synchronized method, and are forced to wait long enough (natObject.cc:907 spins
18 times before making a hard lock) you can drop the finalizer by inserting a
WeakHashMap.put(this, null) call. (I force System.gc() regularly) In gdb I can
see that heavy_lock_obj_finalization_proc is no longer called once the
Reference::create() call has been made. I've done this a ton of times in a
loop, but I just can't get the test app to crash. Is dropping the finalizer
enough to cause a crash (over time)? I'm not sure what I'm missing, or what I
can do to force this crash.
My real app however does crash. I've recompiled libgcj and do get all the
information originally requested from gdb from an above comment in yet another
but similar backtrace. I don't know if it confirms that the problem is in
dropping finalizers (or maybe that is a separate problem?), but thought I'd
post it.

--- Additional Comments From ovidr at users dot sourceforge dot net 2005-07-07 21:24 --- I don't know how to do that with the current configure. Build != Host --build=i686-pc-linux-gnu --host=i686-pc-mingw32 --target=i686-pc-mingw32 >From configure.ac: # If build != host, and we aren't building gas in-tree, we identify a # build->target assembler and hope that it will have the same features # as the host->target assembler we'll be using. (which is wrong in this case) And configure.ac is using 'test -x' on environment variables $AS and $AS_FOR_TARGET, which always have their paths stripped, so I can't set it to "/home/gcc/build/crossgcc/bin/i686-pc-mingw32-as" or "i686-pc-mingw32-as" and pass the "test -x" test, even though that is the $AS that will ultimately be used to assemble. Manually changing the "elif test -x "$AS_FOR_TARGET"; then" line in gcc/configure to "-n" makes it use the env variable, and sets HAVE_GAS_SHF_MERGE 0, which is what I want, but I doubt this is the right way to do it. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22330

[Bug libgcj/18266] SIGSEGV in GC_register_finalizer_inner ()
--- Additional Comments From ovidr at users dot sourceforge dot net 2005-06-20 16:25 --- I've tried to create a testcase but can't seem to get a crash or infinite loop lockup. Anyway, I think I understand conceptually what must be done, but in practice I'm still unsure of how to go about it. You don't seem to have a problem with the call to: _Jv_RegisterFinalizer (this, finalize_reference); only _Jv_RegisterFinalizer (referent, finalize_referred_to_object); but since referent is an arbitrary object, what kind of finalizers can it already have? I'm stumped on how to get access to an arbitrary object's finalizers from natReference.cc. Is it just the heavy_lock structure from natObject that needs to be considered somehow? >From comment #10: "My impression is that natReference.cc already keeps a fairly elaborate data structure to which you should be able to add the prior finalization info" This is the part that confuses me. Not all objects are References, so how would a Reference know about some arbitrary Object's previous finalizers or even attempt to maintain a data structure? And once I have the Object's old finalizer (if there is one), I guess I just run it, and register the new one with "GC_REGISTER_FINALIZER_NO_ORDER(x, x, cd, 0, 0);" from natReference's "finalize_referred_to_object" ? Or am I way off track? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18266

--- Additional Comments From ovidr at users dot sourceforge dot net 2005-06-08 21:14 --- Since this bug seems a bit lost, I've been trying some things on my own without success. Can someone please explain: If "referent" is just a RawData pointer to some Object, how are its previous finalizers supposed to be found? How to append them along with the new finalizer in the correct order (order matters?) to GC_REGISTER_FINALIZER_NO_ORDER (GC_register_finalizer_inner(obj, fn, cd, ofn, ocd, mp)) which seems to be what is used in natObject.cc? The comments in this bug seem to suggest that there is some similar code somewhere that I could lift and hook into natReference.create, but all the code in natObject and String.intern finalization looks very different to my novice-gcj eyes since they don't seem to be working with some foreign object, nor with finalizers that aren't already locally stored in a struct. Secondly, is there any way to craft a testcase for this to know if it has been fixed? I don't fully understand why (based on comment #6) this would ever cause a crash, and waiting many days for the crash of my apps is a very tedious process. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18266

[Bug libgcj/14670] [win32] gcj & high ascii: incorrectly translated / linux: fails to compile
--- Additional Comments From ovidr at users dot sourceforge dot net 2004-12-15 04:59 --- It isn't a compiling problem that I'm trying to illustrate. TestD.java (included above) has a line: String s = "" characters.If these characters were received over a network connection as a byte stream, they would still be converted to a string via the "new String(byte[])" method, which is used in TestD.java. They would then be turned into a String, and displayed, as in the screenshot attached above. gcj doesn't seem to convert the characters properly (not in the same was a sun's java anyway). The testcase and screenshot hopefully communicate what I mean. Anyway, compiling to bytecode is separate issue: gcc version 4.0.0 20041213 (experimental) gcj -C --encoding=UTF-8 TestD.java TestD.java:12: error: malformed UTF-8 character.

--- Additional Comments From ovidr at users dot sourceforge dot net 2004-12-13 00:11 --- I don't know that it is related to the specific patch, I just know that when I filed the general bug it was the time at which the app that I've been compiling for a year suddenly stopped being recognized as a valid app on win32 until 'stripped' of symbols. The original problem was that all apps did not run (application error), due to the weak symbols patch. The secondary problem is that my app which I've been compiling fine for a year and with a previous 4.0 version of gcc no longer is recognized as a valid win32 .exe unless stripped. I'm not sure what else 'strip' does to the executable besides the removal of symbols, so I'm not sure how to track down this problem yet. Another generic swt app works fine without being stripped, so I'm still at a loss on how to target the problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18459

Using the first patch (http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02192.html) works, and small win32 binaries do run, but when I compile my large app (which uses swt), it still isn't recognized as a win32 app (app.exe is not a valid win32 application) unless I 'strip' it. I don't know how to narrow down the cause of this. (binutils-041211) I then tried out the second patch (dwarf) (http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02120.html) (leaving the first patch still applied), along with Bryce's java stacktrace patch. This worked for me as well on a simple app. On a larger app I still need to strip it, and unfortunately swt uses callbacks, so the app receives a SIGSEGV when closing it: Microsoft Visual C++ Runtime Library --- Runtime Error! This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. (somewhere after _Java_org_eclipse_swt_internal_Callback_unbind -- gdb isn't helpful since the app is stripped). Patch comments (in the dwarf patch) mention a libgcc_s.dll being required in the future? I am hoping that does not mean it would have to be included with every gcj compiled .exe created for wide distribution since it would make apps less self-contained on windows. Anyone have hints on getting around this callback issue? Bryce's stacktrace patch is incredibly helpful with gcj-java compiled apps on win32.. pointers to even a quick and dirty solution would be appreciated. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18459

--- Additional Comments From ovidr at users dot sourceforge dot net 2004-12-10 16:35 --- It was a completely fresh checkout to an empty dir (both times). I build a linux->win32 cross. (building on win32 takes way too long due to fork()). For the dwarf2 patch, I had used the one line patch from: "http://sources.redhat.com/ml/binutils/2004-11/msg00249.html"; on the binutils-2.15.91-20040904-1-src.tar.gz from mingw.org. If I don't need any further patches(?), I will try to use binutils directly from cvs and build it again. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18459

I have tried this patch: http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02192.html
but a simple gcj --main=test test.java -o test.exe ; test.exe just results in an
application error popup (on windows).
I have also tried "http://gcc.gnu.org/ml/gcc-patches/2004-11/msg02120.html";
(with the 1 line binutils ld patch to add .jcr), but linking fails:
test.java: undefined reference to `__gcj_personality_v0'
Removing the stuff from cygming.h and remaking my cross compiler makes things
work again.

gcc version 4.0.0 20041130 (experimental) doesn't work.
gcc version 3.3.2 20031022 works fine.
It is due to the

Changing AbstractDetailDialog.java to explicitly import the correct Dialog class
fixes it:

[Bug java/18459] New: linux -> win cross compiler : gcj produces corrupt executables
gcc version 4.0.0 20041113 (experimental)
I produce a cross compiler as I normally do. Host is linux, target is
i686-pc-mingw32, and create a simple test class and compile:
public class test {
public static void main(String[] sa) {
System.out.println("H. World");
}
}
i686-pc-mingw32-gcj --main=test test.java
Copy the a.exe to a win machine, run it, and it has an application error. All
.exe's that are created with gcj fail.
If I create a "hello world" test.c and compile it with i686-pc-mingw32-gcc, and
copy it to the win box it works fine.
The i686-pc-mingw32-gcj I built a month ago works without problem:

[Bug libgcj/18187] New: ava.util.WeakHashMap$WeakEntrySet.next() throws NoSuchElementException during GC
During garbage collection, the WeakHashMap will throw a NoSuchElementException
when performing the methods:
.keySet().toArray()
.clear();
and maybe more. Sun's java does not.
Here is an example:
gcc version 4.0.0 20041014 (experimental)
gcj -main=WH WH.java
import java.util.*;
public class WH {
public static void main(String[] s) {
Thread t = new Thread() {
public void run() {
while (true) {
System.gc();
try {
Thread.sleep(1000);
} catch (Exception e) {
}
}
}
};
WeakHashMap w = new WeakHashMap();
for (int i = 0; i < 1; i++)
w.put(new WH(), null);
t.setDaemon(true);
t.start();
try {
w.clear();
} catch (NoSuchElementException n) {
System.out.println("From .clear(): ");
n.printStackTrace();
}
for (int i = 0; i < 1; i++)
w.put(new WH(), null);
try {
for (int i = 0; i < 1000; i++)
System.out.print("["+w.keySet().toArray().length+"]");
} catch (NoSuchElementException n) {
System.out.println("iFrom .toArray():");
n.printStackTrace();
}
}
}
