Add dependency to bug 50807 which is the placeholder for work regarding B. Assign to Hoda to have her deal w/duplicate elements in the proposal list. Duplication of local variables has been solved in HEAD. This is an error in completion on function reference. It is not major. Reducing severity to normal. See bug 50807 When doing content assist in the parameter list of a function call, there are 2 different modes: with prefix and without prefix. void f( [] //1 void f( 1, [] //2 void f( a[] //3 void f( a, b[] //4 Content assist after the bracket of comma without a prefix (1,2), will return a set of functions with the same name and matching parameters. ie at 1, expect all callable functions called f, at 2 expect all callable functions named f that take more than 1 parameter and whose first parameter can accept a '1'. Content assist after the bracket or comma with a prefix (3, 4) will return completions of variables and fields starting with that prefix. So without a prefix completes function candidates ,with a prefix completes argument candidates. In the original example, you CA at (B) should result in printf being proposed. CA at: printf( "words", n[^SPC] should result in local variables (nMyInt) This defect is verified on build Eclipse build 200405210800 aand CDT build 200405290301, and it passes. Pixy. |
CDT 2.0.0.200404190838 Eclipse (200404131323) Test case: 1. Create a standard C project, call it StdC. 2. Add a file to StdC, call it main.c and insert the following code: #include <stdio.h> int main(int argc, char **argv) { printf("Hello world\n"); int nMyInt = 0; int i = [^SPC] // ** (A) ** printf("\nThis is my number: %d\n", [^SPC] ); // ** (B) } 3. Add a file to StdC, call it makefile and insert the following: all: gcc main.c 4. Enable automatic scanner config and build. (The build will fail, but we are only trying to get the scanner config stuff at this point.) 5. Execute content assist on line (A) (no prefix) RESULT: A completion list is presented to the user that contains duplicate entries for all local variables. 6. Execute content assist on line (B) (no prefix) RESULT: The completion list does not contain any of the local variables and printf() is at the top of the list. EXPECTED: (A) - A completion list with no duplicates. (B) - Local variables should be offered and listed at the top of the completion list.
