Subject [jira] Updated: (GERONIMO-2277) Remove TransactionContextManager
Date Sun, 06 Aug 2006 04:18:14 GMT
     [ http://issues.apache.org/jira/browse/GERONIMO-2277?page=all ]

Dain Sundstrom updated GERONIMO-2277:
-------------------------------------

    Attachment: GERONIMO-2277.patch

I merged all changes from head back into notcm and fixed the m2 build.  I also made a few
changes noted below based on requests for David.  I suggest you test the notcm branch directly.
 If you want to try the merge, use the same command as before, and you'll have to resolve
some conflicts (I have no idea why svn marks them as conflicts).  Here are the commands I
used:

svn co https://svn.apache.org/repos/asf/geronimo/trunk geronimo
cd geronimo

svn merge -r 427246:HEAD https://svn.apache.org/repos/asf/geronimo/branches/dain/notcm .

# resolve the conflicts by taking the files from notcm
mv bootstrap.merge-right* \
   bootstrap
svn resolved bootstrap
chmod u+x bootstrap

mv pom.xml.merge-right* \
   pom.xml
svn resolved pom.xml

mv m2-assemblies/geronimo-boilerplate-j2ee/src/main/resources/var/security/keystores/geronimo-default.merge-right*
\
   m2-assemblies/geronimo-boilerplate-j2ee/src/main/resources/var/security/keystores/geronimo-default
svn resolved m2-assemblies/geronimo-boilerplate-j2ee/src/main/resources/var/security/keystores/geronimo-default

mv m2-assemblies/geronimo-boilerplate-minimal/src/main/resources/var/security/keystores/geronimo-default.merge-right*
\
   m2-assemblies/geronimo-boilerplate-minimal/src/main/resources/var/security/keystores/geronimo-default
svn resolved m2-assemblies/geronimo-boilerplate-minimal/src/main/resources/var/security/keystores/geronimo-default

# run the m2 build or run the m1 build
./bootstrap
mvn clean install

# maven new

> If you use the  Geronimo TransactionContextManager,  you can't use the TransactionManager
interface directly since the TCM needs to know about all TM calls.  Additionally, to use the
TCM you must demarcate all changes in "component context" by starting an unspecified transaction
context.  This is all quite invasive and makes it hard to use our code in third part environments
such as Spring or plain old Tomcat.
> I propose we remove the TransactionContextManager and replaced all uses with a plain
old TransactionManager.  This will also allow us to removed all code from web containers,
app client and timer that was simply demarcating an unspecified transaction context, which
is no longer needed.
