* | | Refactor anonymous lookups in translate_componentsJosh Stone2009-05-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code recursed the entirety of translate_components, and it seemed to be restarting the components list every time, so it would only work if the anonymous portion was the first component. Even then, examining the code output by semok/thirtythree revealed that it wasn't fully translating the locations when multiple anonymous pieces were involved. Instead, it now recurses in a separate function, find_struct_member, which does just enough to find the member die and return. It also builds a vector of the locations passed through, so translate_components can output code for the full chain of anonymity. The generated code for semok/thirtythree's $page->mapping now appears to match the offsets from my manual inspection of struct page. I also added a test for $page->first_page->mapping, which works now but would segfault the old code.
* | | Simplify buildok/context_test.stpJosh Stone2009-05-081-20/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test was using optional probes on uptime_read_proc, which doesn't exist anymore on 2.6.30. The problem is that when those optional probes are skipped, the test doesn't really do anything. For a buildok test of the context functions, the actual probe point doesn't matter, so I've changed it to just a begin probe that calls all of the functions.

* | | PR10102: tolerate the failure related to optional probeWenji Huang2009-05-051-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch will make stap silently accept the failure related to optional probe. It puts try/catch around find_and_build which can cover most probe types. The specific treatment for dwarf_derived_probe in commit ed82b7c902d6a2e26452ec51c9cdb9665dbf9e97 is reverted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | + and * are metacharacters, but should always be used as metacharacters in the expressions, don't escape them. * testsuite/systemtap.syscall/test.tcl (run_one_test): Remove escaping of + and *.

| * | | syscalls testsuite: use different escape sequenceFrank Ch. Eigler2009-04-3031-256/+261
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The syscall testsuite uses embedded "// TEXT" markers in the .c files to designate expected output, kind of like the "dg-" bunch in the gcc test suite. Unfortunately, "//" is not a unique prefix to systemtap tests, and in particular it can occur in the system headers that will be picked up with the "gcc -E -C ..." invocation in test.tcl. So let's switch to "//staptest//". test.tcl is also modified to escape a few more mischevious regexp metacharacters that might sneak past.

* | | Use sockaddr instead of timeval in @cast testJosh Stone2009-04-292-11/+15
| | | | | | | | | | | | | | | | | | | | | | | | Using timeval had problems on big-endian multi-arch platforms (ppc64), because the user tv_sec used in the @cast didn't match the kernel tv_sec used to provide a pointer. Hopefully reading from a sockaddr should be more robust, as that type doesn't appear to need any compat wrappers for multi-archs.

The dwarfless kprobes should be no exception. Also, the way they were exiting was causing an unclean shutdown, so I added tests to badkprobe.exp to make sure that cleanup is always allowed to run.
