| * PR10719 part 1: Partial constant foldingJosh Stone2010-02-231-0/+227
| | | | | | | | | | | | | | | | | | This implements constant folding for if/for/foreach, unary expressions, and ternary expressions. Binary expressions are TODO... * elaborate.cxx (const_folder): New visitor to collapse constants. (semantic_pass_const_fold): Drive everything through const_folder. (semantic_pass_optimize1): Call it.
| * Simplify null_statement constructionJosh Stone2010-02-234-11/+18
| | | | | | | | It only needs a token*, so build that into the constructor.
| * Fixed PR 11269 by properly handling mmap syscall 'fd' argument.David Smith2010-02-238-26/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * testsuite/systemtap.syscall/mmap.c (main): Added mprotect and mremap testing (along with testing of anonymous maps). * tapset/i386/syscalls.stp: In mmap probes, handle the fact that the kernel gets an unsigned long 'fd', but the user-side passes a signed int. * tapset/i386/nd_syscalls.stp: Ditto. * tapset/ia64/syscalls.stp: Ditto. * tapset/powerpc/nd_syscalls.stp: Ditto. * tapset/powerpc/syscalls.stp: Ditto. * tapset/x86_64/nd_syscalls.stp: Ditto. * tapset/x86_64/syscalls.stp: Ditto.
| * Removed rvalue operator check.David Smith2010-02-231-12/+4
| | | | | | | | | | * tapset-procfs.cxx (procfs_var_expanding_visitor::visit_target_symbol): Removed unneeded rvalue operator check.
| * PR 10690 (partial fix). Handle '.=' operator in procfs probes.David Smith2010-02-233-21/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * tapsets.h (var_expanding_visitor): Add 'valid_ops' and 'op' member variables. * tapsets.cxx (var_expanding_visitor::var_expanding_visitor): Set 'valid_ops' to '='. By default, var_expanding_visitor classes only handle the '=' operator. (var_expanding_visitor::visit_assignment): Remember what operator we're handling. When an operator is found that isn't in the 'valid_ops' set, error. * tapset-procfs.cxx (procfs_var_expanding_visitor::procfs_var_expanding_visitor): Add '.=' to the 'valid_ops' set. (procfs_var_expanding_visitor::visit_target_symbol): Handle the '.=' operator when the target variable is an lvalue.

|/ | | | | | | | | | | | | | | | | | * staptree.h (defined_op): New class. * all files: Extend all visitors as appropriate, mostly dummy/pass-through implementation. * parse.cxx (parse_target_symbol): New function, factored out of parse_symbol(). (parse_define_op): New function. * NEWS: Mention it. * parse.h: Corresponding changes. * tapsets.cxx (var_expanding_visitor::visit_defined_op): Implement @defined() semantics.

* Prevent accidental global cleanup triggering for syscall test.tcl.Mark Wielaard2010-02-222-34/+34
| | | | | | | | | | | Later tests might trigger a cleanup and might set the global dir variable leading to the syscall test.tcl trying to do an exec rm -rf on whatever dir was set. So rename proc cleanup and global dir in syscall test.tcl to something a bit less likely to clash. * testsuite/systemtap.syscall/test.tcl: Rename proc cleanup to syscall_cleanup and global dir to syscall_dir. * testsuite/systemtap.syscall/test-debug.tcl: Likewise.
* Tweak shared attach sdt test.Stan Cox2010-02-211-40/+70
| | | | * sdt_misc.exp: Make all semaphore references from the .so
* hwbkpt: simplify diagnostics and codeFrank Ch. Eigler2010-02-212-104/+84
| | | | | | | | | | | * tapsets.cxx (hwbkpt_derivedc_probe_group): Lose max_... field. Rename hwbkpt_probes_vector -> hwbkpt_probes. (enroll): Instead set it here, emit normal suppressible warning if exceeded. (emit_*): Use newline(NN) etc. for proper indentation of generated code. (emit_module_init): Defer most potential problems to register_wide_hw_breakpoint() instead of preemptive errors. * translate.cxx (emit_module_init): Assert 0 indentation more frequently.

* PR11208: glue adjacent string literals together.Frank Ch. Eigler2010-02-194-2/+37
| | | | | * parse.cxx (lexer::scan): Glue adjacent strings together. * testsuite/parseko/twentyseven.stp, semok/thirtyfive.stp: New tests.
* PR11275: be less verbose in case of command line option parsingFrank Ch. Eigler2010-02-191-18/+23
| | | | | * main.cxx (main): exit() instead of printing usage for most errors. Also support --help.
* Allow CONFIG_foo COMPARISON-OP CONFIG_bar in preprocessor conditionals.Mark Wielaard2010-02-192-2/+43
| | | | | | | * parse.cxx (eval_pp_conditional): If rhs and lhs are both CONFIG_... identifiers try to convert them both to numbers or otherwise threat them both as strings for eval_comparison. * testsuite/semok/config_config.stp: New test.
* Allow CONFIG_foo COMPARISON-OP number in preprocessor conditionals.Mark Wielaard2010-02-192-12/+51
| | | | | | * parse.cxx (eval_pp_conditional): Handle r->type == tok_number when l->type == tok_identifier. * testsuite/semok/config_number.stp: New test.

* Improved server certificate management. ulimit for stap-server only.Dave Brolley2010-02-175-47/+85
| | | | | | | - Server now generates a new certificate when old one expires. - Certificates now valid for 1 year. - ulimit for stap-server-connect now only set for stap-server user and only when override variable is not set.
* Use clamping to more easily normalize input valuesJosh Stone2010-02-165-20/+25
| | | | | | The kernel has min/max/clamp macros to make range comparisons easier. Clamp is a newer invention, but we can define it for older kernels in terms of min and max.
* PR11282: Keep the md4 state in the hash copy constructorJosh Stone2010-02-161-1/+1
| | | | | | | | We were getting new hash collisions, because the new hash copy constructor was restarting the md4 computation. Everything from get_base_hash was thus lost. * hash.h (hash::hash): Keep the md4 state when copying.
* PR11277: Use consistent octal in quoted stringsJosh Stone2010-02-163-33/+26
| | | | | | | | | | Previously, our octal escapes used variable lengths, which can lead to ambiguities. Also, 8-bit characters would only output the least digit. * runtime/string.c (_stp_text_str): Always output 3-digit octal escapes, and handle 8-bit chars more gracefully. * testsuite/systemtap.string/text_str.stp: Include an 8-bit character. * testsuite/systemtap.string/text_str.exp: Above + expect 3-digit octal.
* Don't try to parallel install partial build-elfutils build in lib-elfutils.Mark Wielaard2010-02-1613-2663/+4845
| | | | | | | | | | | | | | | | | | | The parallel install into lib-elfutils during the build seems to be fragile, so explicitly install the libs with -j1. * Makefile.am (stamp-elfutils): Add -j1 in for dir loop sub make. * Makefile.in: Regenerated. * aclocal.m4: Likewise. * compile: Likewise. * config.in: Likewise. * configure: Likewise. * doc/Makefile.in: Likewise. * doc/SystemTap_Tapset_Reference/Makefile.in: Likewise. * doc/beginners/Makefile.in: Likewise. * grapher/Makefile.in: Likewise. * testsuite/Makefile.in: Likewise. * testsuite/aclocal.m4: Likewise. * testsuite/configure: Likewise.

| * PR11281 Allow negative values for -D argument.Mark Wielaard2010-02-141-1/+1
| | | | | | | | | | | | | | Change regexp match to "^[a-z_][a-z_0-9]*(=-?[a-z_0-9]+)?$". * main.cxx (main): case 'D' allow optional single minus sign after equal in assert_regexp_match().
| * Test for sendfile syscall can handle non-socket fds now.Mark Wielaard2010-02-131-4/+4
| | | | | | | | | | | | | | | | Since 2.6.33 sendfile can handle non-socket fds, so make the test handle both success and failure. * testsuite/systemtap.syscall/sendfile.c (main): Make buffer 22 bytes, since 22 == EINVAL, test for 22 bytes send or -22 failure.

| * Add simple test for PR10257 (sprint(@hist_linear)).Przemysław Pawełczyk2010-02-112-0/+18
| | | | | | | | | | | | | | | | | | | | Test is simple, because print and sprint uses the same code for handling @hist_* and it is not intended for playing with MAXSTRINGLEN, which is required anyway for bigger histograms (the one generated here consists of only 127 characters). When PR10690 (need way to produce bigger procfs output) will be fixed, then we should add another test for both PRs with normal histogram.
| * Fixed PR 11270 by adding nd_syscall testcase.David Smith2010-02-104-2/+99
| | | | | | | | | | | | | | | | | | | | * testsuite/systemtap.syscall/test.tcl: Now uses global variable 'test_script' to find test script to run. * testsuite/systemtap.syscall/syscall.exp: Sets test_script. * testsuite/systemtap.syscall/nd_sys.stp: New test script. Copy of sys.stp, but uses nd_syscall probes. * testsuite/systemtap.syscall/nd_syscall.exp: New testcase. Copy of syscall.exp, but uses nd_sys.stp test script.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Some distributions might have backported the pipe fd leak patch and removed the sys32_pipe kernel function even before 2.6.32. So make the probe alias optional instead of relying on a version check. * tapset/x86_64/syscalls.stp (syscall.pipe): Make alias optional. (syscall.pipe.return): Likewise.
