The API function advert::entry::store_string and retrieve_string need to be renamed to be overloads of the store_object/retrieve_object functions, without an ychange in semantics.

The SAGA spec defines an 'order' of exceptions, from more specific to less specific. Functions must throw the most specific exception possible, which makes sense. However, the C++ engine uses the same order for the type of the nested exception reported to an application. This does not make sense when there are multiple adaptors implementing the same functionality.

Example: a user creates an FTP file:

saga::file f("ftp://host.com/file.txt", saga::filesystem::Exclusive);

This file happens to already exist, so this call should throw an already_exists exception. Say the engine has two file adaptors: a local one and an FTP adaptor. The local adaptor will throw an incorrect_url exception in its constructor, since it cannot handle FTP URLs. The FTP adaptor will try to create the file and throw an already_exist exception. The type of the nested exception reported by the engine to the user will then be incorrect_url, since that one is 'more specific' than already_exists.

Worse, if one adaptor does not implement a method, its not_implemented exception will overrule all more sensible exceptions from adaptors that do implement that method. This is clearly not what a user wants.

For a multi-adaptor engine, it makes much more sense to 'order' the exception types differently. In the Java engine, we currently 'invented' this order (from more to less specific):

AlreadyExistsException, DoesNotExistException, IncorrectStateException, TimeoutException, AuthenticationFailedException, AuthorizationFailedException, PermissionDeniedException, BadParameterException, IncorrectURLException, NoSuccessException, NotImplementedException.

Rationale: if two adaptors report two different exceptions, a user would probably like to see the first one in this list. Shouldn't the C++ engine do something similar?

When trying to compile SAGA with python bindings (python 2.6, boost 1.36) I get the following in the python config.log file: conftest.o(.text+0x4b): In function `static_initialization_and_destruction_0': /work/yye00/boost_install//include//boost-1_36/boost/python/refcount.hpp:16: undefined reference to `_Py_NoneStruct' conftest.o(.text+0x63): In function `static_initialization_and_destruction_0': /work/yye00/boost_install//include//boost-1_36/boost/python/object_core.hpp:429: undefined reference to `_Py_NoneStruct' conftest.o(.text+0x95): In function `main': /scratch/yye00/SAGA/trunk/bindings/saga/python/conftest.cpp:24: undefined reference to `Py_Initialize' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PySequence?_DelSlice' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyNumber?_InPlaceXor' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyInt?_FromLong' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyNumber?_Subtract' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyMem?_Malloc' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyComplex?_RealAsDouble' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyModule?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyDict?_Keys' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyMethod?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyExc?_ReferenceError' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PySequence?_SetSlice' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyObject?_GetAttr' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyExc?_RuntimeError' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyObject?_CallFunction' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyNumber?_InPlaceDivide' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyDict?_Copy' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyErr?_ExceptionMatches' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyFloat?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyString?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyNumber?_Or' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyUnicodeUCS2_AsWideChar' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyUnicode?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyNumber?_Xor' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyStaticMethod?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyExc?_OverflowError' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyDict?_Clear' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyObject?_ClearWeakRefs' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyErr?_SetString' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyErr?_WarnEx' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyComplex?_Type' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyLong?_AsUnsignedLongLong' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyErr?_Occurred' /work/yye00/boost_install//lib/libboost_python-gcc42-mt.so: undefined reference to `PyBaseObject?_Type'

Please assist.

verisoning of library names allows multiple versions to coexist. We should support that.

Connected to that, saga/saga/version.hpp should be generated by configure, and version infos should be taken from SAGA_ROOT/VERSION.

With the default configuration, if an application starts a Condor job and exits before it terminates, the temporary log file used to track the job will be left in the system's temporary directory.

The adaptor does try to cleanup on exit, but subsequent job events will cause Condor to recreate the log file.

More info here: https://lists.cs.wisc.edu/archive/condor-devel/2008-August/msg00003.shtml

... should be part of the 0.9.4 release!

Hi,

I'm trying to glue together your SAGA C++ Python bindings and the following (higher level) Python SAGA language binding: http://www.few.vu.nl/~pzn400/apidoc/[[BR]] I discovered that there are some methods missing, which are present in the actual C++ API, but not exposed to the Python layer. For example, I didn't find a way to read buffer data into a variable. The methods buffer.get_data() and buffer.set_data() are missing.

Should I file more bugs if I find some more missing methods or do you prefer another way?

Thanks very much,
/Manuel

I am trying to use the SAGA context API to manage different X509 proxies on top of the Globus adaptor: I extracted the key points into following python program:

import saga

s = saga.session()
userproxy="/home/luckow/.globus/teraproxy.pem"
ctx = saga.context("globus")
ctx.set_attribute ("UserProxy", userproxy);
ctx.set_defaults ();
s.add_context(ctx)

#register advert entry
lrms_saga_url = saga.url("gram://grid-abe.ncsa.teragrid.org/jobmanager-pbs")
jd = saga.job.description()
jd.numberofprocesses = "1"
jd.spmdvariation = "single"
jd.arguments = ["hello world"]
jd.executable = "/bin/echo"
jd.queue = "loni_jha_big@workq"
jd.workingdirectory = "$(HOME)"
jd.output = "stdout.txt"
jd.error = "stderr.txt"

js = saga.job.service(s, lrms_saga_url)
job = js.create_job(jd)
print "Submit to: " + str(lrms_saga_url)
job.run()

However, the context does not pick up the proxy correctly. As a matter of fact the program already holds during initialization of the context:

Successfully created CPI: context_cpi using adaptor instance: globus_gsi_context SAGA(NoSuccess?): globus_gsi_context: globus_gsi_context_adaptor.cpp(91): Couldn't find a valid proxy in /tmp/x509up_u<uid>.

I have of course no standard proxy initialized since I want to use a custom proxy location.
