    v76 v77  
    212212           * I am not sure as to how to 'convert' the stack address to a shared memory object name
    213213             
    214  
     214* '''July 15:''' Seventh Meeting
     215      * ''Progress:''
     216           * Completed stack-sharing mechanism, I will hopefully send the patch today.
     217           * Started with the implementation of High-level API for stack sharing.
     218      * ''Goals for this week:''
     219           * Complete the implementation of the High-level POSIX APIs.
     220           * Write a test which demonstrates strict thread-stack isolation and stack-sharing of the isolated stacks.
     221      * ''Blockers:''
     222           * I plane to rectify the patches that I sent before continuing with my implementation and this can take a day or two before
     223             I get my code perfect
     224
     225* '''July 22:''' Eighth Meeting
     226      * ''Progress:''
     227           * Completed stack_address naming mechanism.
     228           * Completed High-level API for stack sharing.
     229           * Changed the protected stack tracking mechanism, integrated it with thread control block
     230             and simplified the stack tracking mechanism.
     231      * ''Blockers:''
     232           * While writing tests for stack-isolation and sharing I realized a very major flaw in my implementation.
     233           * Currently, the translation table for the complete stack-space is set in a single level (i.e. sections),
     234             this means that the second-level table is not set initially. Now when I try to change the memory entries
     235             of the alllocated stacks dynamically in page format, it sets invalid entries as the entries were not
     236             previously set for the second level table
     237      * ''Goals for this week:''
     238           * Resolve the above-mentioned issue.
     239           * Get feedback on my implementation and make changes accordingly.
     240           * Complete the test for stack-isolation and sharing by using the high-level APIs
