#34: Initialization + declaration: invalid reorder ---------------------------+------------------------------------------------ Reporter: dkimpe | Owner: Type: defect | Status: new Priority: major | Component: code generator Version: git repository | Keywords: ---------------------------+------------------------------------------------ In the following (accepted by the compiler): {{{ ... init_a (); int my_var = call_b (); ... }}} my_var gets moved to the context structure (correct); However, it gets initialized at the beginning of the function, effectively moving {{{call_b}}} before {{{init_a}}} in the example. This can be a very hard to track down bug... Possible solution: disallow behavior in source translator or fix. -- Ticket URL: <https://trac.mcs.anl.gov/projects/aesop/ticket/34> aesop <https://trac.mcs.anl.gov/projects/aesop> The Aesop Language

#22: overriding CFLAGS in make or configure causes build to fail. ---------------------------+------------------------------------------------ Reporter: dkimpe | Owner: Type: defect | Status: new Priority: minor | Component: build system Version: git repository | Keywords: ---------------------------+------------------------------------------------ Configuring aesop using CFLAGS="-O2" (i.e. ./configure CFLAGS="-O2") or issuing make CFLAGS="-O2" causes the build to fail. One reason is that it overrides the -I needed to find aesop.h. This most likely is a bug in Makefile.in and/or aecc -- Ticket URL: <http://trac.mcs.anl.gov/projects/aesop/ticket/22> aesop <https://trac.mcs.anl.gov/projects/aesop> The Aesop Language

Weekly report
by guoxinl＠clemson.edu 16 Jun '14

16 Jun '14

Dear all, In this week, we analyzed the test results of a proximity-aware file replication method, which copies data to the hubs of all request paths in a P2P file storage. We compared the performance with other methods, which replicates files onto client-side, server-side and hot paths. In this week, we will study a replication method based on a hybrid structure with both structured and unstructured P2P overlay in order to achieve a better tradeoff between replication overhead and request latencies.

[aesop] #66: unusual warnings produced by aecc with gcc 4.8 or higher

#66: unusual warnings produced by aecc with gcc 4.8 or higher ---------------------------+------------------------------------------------ Reporter: carns | Owner: Type: defect | Status: new Priority: minor | Component: parser Version: git repository | Keywords: ---------------------------+------------------------------------------------ Example: {{{ ../src/socket/aesocket.ae: At top level: __blocking int aesocket_accept( ^ __blocking int aesocket_accept( ^ __blocking int aesocket_read( ^ __blocking int aesocket_read( ^ __blocking int aesocket_write( ^ __blocking int aesocket_write( ^ }}} Incomplete warnings like this (or similar) appear in most .ae file compilations, but it doesn't seem to be hurting anything. Maybe these are warnings produced in the generated c code that aecc normally filters out? The error/warning message format in gcc has changed so the filters may be broken if so. -- Ticket URL: <https://trac.mcs.anl.gov/projects/aesop/ticket/66> aesop <https://trac.mcs.anl.gov/projects/aesop> The Aesop Language

Request for delay
by Richard Brooks 03 Feb '14

03 Feb '14

Would it be possible to delay this month's teleconference from 2/3 to 2/17? Jingxuan will be doing the presentation this time. She has it ready and is ready to present it. I would rather be present for the discussion, though, if at all possible. Unfortunately, next week (all week) I am at Harvard for a program review for my State Dept. project. On 2/10, I will be at ORNL for a program review for my DHS project. That leaves 2/17. If this does not work for the others I understand, but if possible I would like to be there for the discussion on Jingxuan's presentation. Thank you for your understanding. Let us know if this delay is possible. -RRB -- =================== R. R.

Hi, all, Last two weeks, I have finished integrating shibboleth with authentication( Kerberos and X.509). From this week, we will resume working on XACML, including more specific verification tests and implementation of XACML PEP, and also the integration Shibboleth with XACML.
