| |/ | | | | | | tcl.exp: Initialize xok
| * Fixed BZ559643 by doing 'spawn;expect;wait' instead of 'spawn;wait;expect'.David Smith2010-02-081-17/+26
| | | | | | | | | | | | * testsuite/systemtap.base/labels.exp: Corrected order of 'spawn;expect;wait' calls. Added 'wait' calls when needed. Also, doesn't run the "labels exe .label" test if uprobes isn't supported.

| | | | | | | | * tapsets-mark.cxx, tapsets.cxx: Don't even publish probe point families that are inappropriate for use in --unprivileged mode.

| * PR11234: Rewrite __get_argv without embedded-CJosh Stone2010-02-041-115/+44
| | | | | | | | | | | | We now implement __get_argv's string building in pure stap script. Also, every argument is now quoted, which is different than before, but it's much more robust about handling special characters.
| * Revert "PR11234: Ensure __get_argv doesn't overflow"Josh Stone2010-02-043-82/+11

| * Do not check stuff required by server if disabled.Przemyslaw Pawelczyk2010-02-041-29/+31
| | | | | | | | | | | | | | | | | | | | | | | | Building systemtap package using dpkg-buildpackage under scratchbox yields following error during configure: checking for /usr/include/nss3... configure: error: cannot check for file existence when cross compiling even if --disable-server is provided. Fix it. * configure.ac: Check for server-related stuff iff enable_server != no.

| * Fixed PR 11078. Changed code to avoided procfs race condition.David Smith2010-02-033-68/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * runtime/procfs.c: Allow STP_MAX_PROCFS_FILES define to be overridden. (_stp_create_procfs): Calls proc_create() instead of create_proc_entry() to avoid a race condition. * runtime/procfs-probes.c: New file containing procfs probe support routines. * tapset-procfs.cxx (procfs_derived_probe::join_group): Update struct _stp_procfs_data definition. (procfs_derived_probe::emit_module_decls): Include procfs-probes.c, which is where the definition of struct stap_procfs_probe exists. Update generated routines to read/write procfs data. (procfs_derived_probe_group::emit_module_init): Pass file_operations argument to _stp_create_procfs(). Initialize mutex. (procfs_var_expanding_visitor::visit_target_symbol): Update generated code.
| * PR9931: generate log to help diagnosing occasional cache hash collisionsWenji Huang2010-02-033-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ideas from Frank Ch. Eigler: - extending the hash.add() function to pass names along with the hash-mix values, so that class hash can internally track the hash-report string - storing the reports themselves in the cache, beside the .ko / .c files, and changing the cache-size-limit logic to delete these .txt files upon garbage collection * hash.h : New member parm_stream. * hash.cxx (get_parms): New function to convert parms stream to string. (hash::add): Aggregrate parms stream. (create_hash_log): New function to log hash operation. (find_*_hash): Log hash at the end of function. * cache.cxx (clean_cache): Remove log when cache reaches limitation.
| * Fix procfs_write.exp so that it will pass under RHELl5.David Smith2010-02-022-2/+6
| | | | | | | | | | | | | | * testsuite/systemtap.base/procfs_write.exp: Small changes for RHEL5 support. * testsuite/lib/stap_run.exp (stap_run): Increase maximum number of characters to match against.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dwflpp::translate_location() works on the dw address space, but get_cfa_ops() starts out with dwfl calls (only dwarf_cfi_addrframe() needs to be adjusted for bias). * dwflpp.cxx (translate_location): Pass pc plus module bias through to get_cfa_ops. (get_cfa_ops): Adjust for bias when calling dwarf_cfi_addrframe(), add frame start/end address when found if verbose logging. * testsuite/systemtap.exelib/lib.stp: Add $foo and $bar variables to process.function probes. * testsuite/systemtap.exelib/libmarkunamestack.stp: Likewise. * testsuite/systemtap.exelib/lib.tcl: Expect correct values for process.function probe variables. * testsuite/systemtap.exelib/libmarkunamestack.tcl: Likewise.

| | | | | | | | | | | | | | That function was calling strlcpy as if the return value was the number of bytes copied, but strlcpy actually returns the length of the input string. We now use min() to handle the case when it's bigger than the buffer length, and drop out of the loop when that happens.
