2013-05-30maintenance_expand_symtabs leaks a cleanupTom Tromey2-0/+6
It turns out that maintenance_expand_symtabs was missing a call to do_cleanups. I found this using the cleanup checker. * symmisc.c (maintenance_expand_symtabs): Call do_cleanups.
2013-05-30fix up xml-support.cTom Tromey3-36/+25
xml-support.c has a function that returns a cleanup via an out parameter. This changes this function to be a normal cleanup constructor -- returning the cleanup directly and returning the other result via an out parameter. This is sort of a hack, but it lets the checker work here. I also noticed that gdb_xml_create_parser_and_cleanup does not need to be exported any more. * xml-support.c (gdb_xml_create_parser_and_cleanup): Rename from gdb_xml_create_parser_and_cleanup_1. Return a cleanup. Remove 'old_chain' argument. Add 'parser_result' argument. (gdb_xml_create_parser_and_cleanup): Remove old version. (gdb_xml_parse_quick): Update. (xml_process_xincludes): Update. * xml-support.h (gdb_xml_create_parser_and_cleanup): Don't declare.
2013-05-30fix compile_rx_or_errorTom Tromey3-7/+16
compile_rx_or_error looks like a constructor, but it can return NULL. This patch changes it to remove the NULL return, making it work like any other cleanup constructor. This is a stylistic patch but I think it is also better for code to follow the normal conventions. * probe.c (collect_probes): Check arguments for NULL before calling compile_rx_or_error. * utils.c (compile_rx_or_error): Require 'rx' to be non-NULL. Remove NULL return.
2013-05-30some fixes to infrun.cTom Tromey2-4/+8
This fixes some of the problems in infrun.c that the checker reported. I filed the remaining problems as bugs. This patch is purely stylistic. * infrun.c (adjust_pc_after_break): Introduce an outer null cleanup.
2013-05-30fix mi-cmd-var.cTom Tromey2-4/+7
This is a stylistic change in mi-cmd-var.c that adds outer cleanups where needed by the checker. * mi/mi-cmd-var.c (varobj_update_one): Add an outer null cleanup.
2013-05-30fix cli-script.cTom Tromey2-12/+12
read_command_lines_1 had some (IMNSHO) spaghetti-ish code for cleanup handling. This makes the code much simpler to understand, by introducing an outer cleanup. This is another case where a stylistic change for the checker is also nice for the reader. * cli/cli-script.c (read_command_lines_1): Use a null cleanup for 'old_chain'. Do not check 'head' before processing cleanups.
2013-05-30fix mi-cmd-stack.cTom Tromey2-4/+6
mi-cmd-stack.d had a conditional cleanup, "cleanup_tuple" that confused the checker. However, there was no need for this, since it was only used via do_cleanups at the end of the function, just before another call to do_cleanups. So, while this is a stylistic patch for the checker, I also consider it a generic improvement for readers of the code. * mi/mi-cmd-stack.c (list_arg_or_local): Remove "cleanup_tuple".
2013-05-30fix dbxread.cTom Tromey2-5/+11
This is a stylistic change to make some code in dbxread.c analyzable by the checker. * dbxread.c (dbx_read_symtab): Declare 'back_to' in a more inner scope. Unconditionally call do_cleanups.
2013-05-30fix source.cTom Tromey2-0/+8
find_and_open_source can leak a cleanup. * source.c (find_and_open_source): Call do_cleanups.
2013-05-30fix linux-thread-db.cTom Tromey2-4/+9
This is a stylistic change to make it so the checker can analyze a function in linux-thread-db.c. * linux-thread-db.c (thread_db_load_search): Unconditionally call do_cleanups.
2013-05-30fix in solib-aix.cTom Tromey2-2/+7
solib_aix_bfd_open has an early "return" that doesn't run cleanups. This fixes the problem by dropping the null_cleanup and using a later cleanup as the master cleanup for the function. * solib-aix.c (solib_aix_bfd_open): Don't use a null cleanup for 'cleanup'; instead use a later one.
2013-05-30use explicit returns to avoid checker confusionTom Tromey4-3/+13
The checker does not understand the idiom if (except.reason < 0) { do_cleanups (whatever); GDB_PY_HANDLE_EXCEPTION (except); } because it doesn't realize that the nested 'if' actually has the same condition. This fixes instances of this to be more explicit. * python/py-breakpoint.c (bppy_get_commands): Use explicit, unconditional return. * python/py-frame.c (frapy_read_var): Likewise. * python/python.c (gdbpy_decode_line): Likewise.
2013-05-30fix cp-namespace.cTom Tromey2-1/+9
cp_lookup_symbol_imports_or_template could return without running cleanups. * cp-namespace.c (cp_lookup_symbol_imports_or_template): Call do_cleanups on all return paths.
2013-05-30fix top.cTom Tromey2-0/+5
execute_command can leak a cleanup along one return path. * top.c (execute_command): Discard 'cleanup_if_error' cleanups.
2013-05-30fix one bug in stabsread.cTom Tromey2-1/+9
Some code in stabsread.c can return without running cleanups. * stabsread.c (read_struct_type): Call do_cleanups along all return paths.
2013-05-30 * mips-linux-tdep.c: Adjust formatting throughout.Maciej W. Rozycki2-59/+60
2013-05-30fix mipsread.cTom Tromey2-5/+25
Some code in mipsread.c could leak cleanups along some return paths. * mipsread.c (read_alphacoff_dynamic_symtab): Call do_cleanups along all return paths.
2013-05-30fix one bug in symfile.cTom Tromey2-2/+13
find_separate_debug_file could leak a cleanup along some return paths. * symfile.c (find_separate_debug_file): Call do_cleanups along all return paths.
2013-05-30fix symtab.cTom Tromey2-1/+6
search_symbols had some bad code resulting in a cleanup being both discarded and run. * symtab.c (search_symbols): Introduce a null cleanup for 'retval_chain'.
2013-05-30fix py-value.cTom Tromey2-2/+13
Some code in py-value.c could exit a loop without running some cleanups made in the loop. * python/py-value.c (valpy_binop): Call do_cleanups before exiting loop.
2013-05-30fix py-prettyprint.cTom Tromey2-2/+5
print_children, in py-prettyprint.c, could call do_cleanups twice on the same cleanup. * python/py-prettyprint.c (print_children): Remove extra do_cleanups call.
2013-05-30fix py-frame.cTom Tromey2-1/+11
A couple return paths in frapy_read_var were missing do_cleanups calls. * python/py-frame.c (frapy_read_var): Call do_cleanups along all return paths.
2013-05-30fix py-breakpoint.cTom Tromey2-1/+10
One return path in bppy_get_commands was missing a do_cleanups call. * python/py-breakpoint.c (bppy_get_commands): Call do_cleanups along all return paths.
2013-05-30simplify cli-logging.c for analysisTom Tromey2-4/+10
This is another stylistic patch. It changes cli-logging.c to be analyzable by the checker, again following the method of adding an outer cleanup and unconditionally calling do_cleanups. * cli/cli-logging.c (set_logging_redirect): Unconditionally call do_cleanups.
2013-05-30fix varobj.cTom Tromey2-3/+6
c_value_of_root is missing a call to do_cleanups at one return. This fixes the problem by removing that return and letting control fall through. * varobj.c (c_value_of_root): Call do_cleanups along all return paths.
2013-05-30make a cleanup unconditionally in tracepoint.cTom Tromey2-4/+9
This is another cosmetic patch. It introduces an "outer" cleanup in trace_dump_command and arranges to unconditionally call do_cleanups. This lets the checker analyze the function. * tracepoint.c (trace_dump_command): Unconditionally call do_cleanups.
2013-05-30fix two buglets in breakpoint.cTom Tromey2-4/+10
First, output_thread_groups leaks a cleanup along one return path. Second, parse_cmd_to_aexpr could return without running its cleanups, if there was an exception in a TRY_CATCH. * breakpoint.c (output_thread_groups, parse_cmd_to_aexpr): Call do_cleanups earlier.
2013-05-30fix cleanup handling in macho_symfile_readTom Tromey2-2/+7
macho_symfile_read leaks a cleanup by assigning to 'back_to' too late. * machoread.c (macho_symfile_read): Assign first cleanup to 'back_to'.
2013-05-30fix cleanup handling in m32r_loadTom Tromey2-0/+5
m32r_load is missing a call to do_cleanups along one return path. * m32r-rom.c (m32r_load): Call do_cleanups at all returns.
2013-05-30fix list_available_thread_groupsTom Tromey2-1/+8
list_available_thread_groups, in mi-main.c, leaks a cleanup. This changes it to call do_cleanups. * mi/mi-main.c (list_available_thread_groups): Call do_cleanups.
2013-05-30cleanup fixes for inf-ptrace.cTom Tromey2-8/+12
This is one of the stylistic patches. The code here in inf-ptrace.c is not incorrect, but it is in a style that the cleanup checker cannot handle. This patch changes it to a simpler style, following the usual method of introducing an unconditional "outer" cleanup. * inf-ptrace.c (inf_ptrace_create_inferior): Unconditionally call discard_cleanups. (inf_ptrace_attach): Likewise.
2013-05-30cleanup fixes for remote-mips.cTom Tromey2-4/+22
remote-mips.c has a few 'return's where cleanups are not run. * remote-mips.c (mips_exit_debug): Call do_cleanups on all return paths. (mips_initialize): Likewise. (common_open): Call do_cleanups.
2013-05-30fix up cleanup handling in internal_vproblemTom Tromey2-0/+6
internal_vproblem can return, so this introduces proper cleanup handling there. Otherwise it may make a cleanup that is leaked. * utils.c (internal_vproblem): Call do_cleanups.
2013-05-30fix linespec bug noticed by the checkerTom Tromey2-1/+5
This fixes a linespec bug noticed by the cleanup checker. find_linespec_symbols did this: cleanup = demangle_for_lookup (name, state->language->la_language, &lookup_name); [...] cleanup = make_cleanup (xfree, canon); But this is wrong, as it makes a subsequent call to do_cleanups not clean up all the local state. * linespec.c (find_linespec_symbols): Don't reassign to 'cleanup'.
