2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1
This commit brings all the changes made by running gdb/copyright.py as per GDB's Start of New Year Procedure. For the avoidance of doubt, all changes in this commits were performed by the script.
2021-07-30Replace exception_print_same with operator!=Tom Tromey1-3/+0
I noticed that exception_print_same is only used in a single spot, and it seemed to be better as an operator!= method attached to gdb_exception. Regression tested on x86-64 Fedora 34.

2019-04-25Make exception handling more efficientTom Tromey1-4/+6
This makes exception handling more efficient in a few spots, through the use of const- and rvalue-references. I wrote this patch by commenting out the gdb_exception copy constructor and then examining the resulting error messages one by one, introducing the use of std::move where appropriate. gdb/ChangeLog 2019-04-25 Tom Tromey <tromey@adacore.com> * xml-support.c (struct gdb_xml_parser) <set_error>: Take an rvalue reference.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2017-10-10Eliminate catch_exceptions/catch_exceptions_with_msgPedro Alves1-42/+0
This patch gets rid of catch_exceptions / catch_exceptions_with_msg. The latter is done mostly by getting rid of the three remaining vestigial libgdb wrapper functions, which are really pointless nowadays. This results in a good number of simplifications. (I checked that Insight doesn't use those functions.) The gdb.mi/mi-pthreads.exp change is necessary because this actually fixes a bug, IMO -- the patch stops MI's -thread-select causing output on the CLI stream. I.e., before: -thread-select 123456789 &"Thread ID 123456789 not known.\n" ^error,msg="Thread ID 123456789 not known." (gdb) After: -thread-select 123456789 ^error,msg="Thread ID 123456789 not known."

2017-10-10Eliminate catch_errorsPedro Alves1-25/+7
If you want to use catch_errors with a function with parameters, then currently you have to manually write a "capture" struct wrapping the arguments and marshall/unmarshall that. https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed adjusting catch_errors to use gdb::function_view, which would allow passing lambdas with automatic captures. However, it seems like using TRY/CATCH directly instead ends up producing clearer and easier to debug code. This is what this commit does. Note that removing catch_errors exposes further cleanup opportunities around no longer having to follow catch_errors callback type, and also removes a few cleanups. I didn't do anything to save/restore current_uiout because I think that should be the responsibility of the code that changes current_uiout in the first place. (Another approach could be to make catch_errors a variadic template like: template<typename Function, typename... Args> int catch_errors (const char *errstring, return_mask mask, Function &&func, Args... args); and then with: extern void function_with_args (int, int); extern void function_with_no_args (); calls to the above functions would be wrapped like this: catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_args, arg1, arg2); catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_no_args); but I'm thinking that that doesn't improve much if at all either.) gdb/ChangeLog 2017-10-10 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * breakpoint.c (breakpoint_cond_eval): Change return type to bool and reverse logic.

This applies the second part of GDB's End of Year Procedure, which updates the copyright year range in all of GDB's files. gdb/ChangeLog: Update copyright year range in all GDB files.
2016-10-26PR 20569, segv in follow_execSandra Loosemore1-0/+3
The following testcases make GDB crash whenever an invalid sysroot is provided, when GDB is unable to find a valid path to the symbol file: gdb.base/catch-syscall.exp gdb.base/execl-update-breakpoints.exp gdb.base/foll-exec-mode.exp gdb.base/foll-exec.exp gdb.base/foll-vfork.exp gdb.base/pie-execl.exp gdb.multi/bkpt-multi-exec.exp gdb.python/py-finish-breakpoint.exp gdb.threads/execl.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp The immediate cause of the segv is that follow_exec is passing a NULL argument (the result of exec_file_find) to strlen. However, the problem is deeper than that: follow_exec simply isn't prepared for the case where sysroot translation fails to locate the new executable. Actually all callers of exec_file_find have bugs due to confusion between host and target pathnames. This commit attempts to fix all that. In terms of the testcases that were formerly segv'ing, GDB now prints a warning but continues execution of the new program, so that the tests now mostly FAIL instead. You could argue the FAILs are due to a legitimate problem with the test environment setting up the sysroot translation incorrectly. A new representative test is added which exercises the ne wwarning code path even with native testing. Tested on x86_64 Fedora 23, native and gdbserver. gdb/ChangeLog: 2016-10-25 Sandra Loosemore <sandra@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> Pedro Alves <palves@redhat.com> PR gdb/20569 * exceptions.c (exception_print_same): Moved here from exec.c. * exceptions.h (exception_print_same): Declare. * exec.h: Include "symfile-add-flags.h".

2014-07-24Rationalize "fatal" error handling outside of gdbserverGary Benson1-1/+3
GDB and gdbserver have functions named "fatal" that are used in completely different ways. In gdbserver "fatal" is used to handle critical errors: it differs from "error" in that "fatal" causes gdbserver to exit whereas "error" does not. In GDB "fatal" is used to abort the current operation and return to the command level. This is implemented by throwing a non-error "RETURN_QUIT" exception. This commit removes GDB's "fatal" and "vfatal" functions entirely. The exception-throwing function "throw_vfatal" is renamed as "throw_vquit", and a new convenience function "throw_quit" is added. The small number of calls to "fatal" are replaced with calls to "throw_quit", making what is happening more obvious. This commit also modifies GDB's "throw_error" to call "throw_verror" rather than calling "throw_it" directly. This change means the assignment of RETURN_ERROR as the exception type now happens in precisely one place in GDB rather than two. gdb/ 2014-07-24 Gary Benson <gbenson@redhat.com> * exceptions.h (throw_vfatal): Renamed to...

2014-01-09Handle the case of a remote target supporting target side commands, but not ↵Pedro Alves1-0/+3
on software breakpoints. Although we can tell upfront whether a remote target supports target side commands, we can only tell whether the target supports that in combination with a given breakpoint kind (software, hardware, watchpoints, etc.) when we go and try to insert such a breakpoint kind the first time. It's not desirable to make remote_insert_breakpoint simply return -1 in this case, because if the breakpoint was set in a shared library, insert_bp_location will assume that the breakpoint insertion failed because the library wasn't mapped in. insert_bp_location already handles errors/exceptions thrown from the target_insert_xxx methods, exactly so the backend can tell the user the detailed reason the insertion of hw breakpoints failed. But, in the case of software breakpoints, it discards the detailed error message. So the patch makes insert_bp_location use the error's message for SW breakpoints too, and, introduces a NOT_SUPPORTED_ERROR error code so that insert_bp_location doesn't confuse the error for failure due to a shared library disappearing. The result is: (gdb) c Warning: Cannot insert breakpoint 2: Target doesn't support breakpoints that have target side commands. 2014-01-09 Pedro Alves <palves@redhat.com> Hui Zhu <hui@codesourcery.com> PR gdb/16101 * breakpoint.c (insert_bp_location): Rename hw_bp_err_string to bp_err_string.

2013-12-12Eliminate UNSUPPORTED_ERROR.Pedro Alves1-3/+0
I have a case that could use an exception for "unsupported feature". I found UNSUPPORTED_ERROR, but looking deeper, I think as is, reusing it for other things would be fragile. E.g., if the Python script sourced by source_script_from_stream triggers any other missing functionality that would result in UNSUPPORTED_ERROR being propagated out to source_script_from_stream, that would confuse the error for Python not being built into GDB. This patch thus redoes things a little. Instead of using an exception for the "No Python" scenario, check whether Python is configured in before actually trying to source the file. It adds a new function instead of using #ifdef HAVE_PYTHON directly, as that is better at avoiding bitrot, as both Python and !Python paths are visible to the compiler this way. Tested on Fedora 17, with and without Python. gdb/ 2013-12-12 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (source_script_from_stream) Use have_python instead of catching UNSUPPORTED_ERROR. * exceptions.h (UNSUPPORTED_ERROR): Delete. * python/python.c (source_python_script) [!HAVE_PYTHON]: Internal error if called. * python/python.h (have_python): New static inline function.

2013-12-03Add "undefined-command" error code at end of ^error result...Joel Brobecker1-0/+3
... when trying to execute an undefined GDB/MI command. When trying to execute a GDB/MI command which does not exist, the current error result record looks like this: -unsupported ^error,msg="Undefined MI command: unsupported" The only indication that the command does not exist is the error message. It would be a little fragile for a consumer to rely solely on the contents of the error message in order to determine whether a command exists or not. This patch improves the situation by adding concept of error code, starting with one well-defined error code ("undefined-command") identifying errors due to a non-existant command. Here is the new output: -unsupported ^error,msg="Undefined MI command: unsupported",code="undefined-command" This error code is only displayed when the corresponding error condition is met. Otherwise, the error record remains unchanged. For instance: -symbol-list-lines foo.adb ^error,msg="-symbol-list-lines: Unknown source file name." For frontends to be able to know whether they can rely on this variable, a new entry "undefined-command-error-code" has been added to the "-list-features" command. Another option would be to always generate an error="..." variable (for the default case, we could decide for instance that the error code is the empty string). But it seems more efficient to provide that info in "-list-features" and then only add the error code when meaningful. gdb/ChangeLog: (from Pedro Alves <palves@redhat.com>) (from Joel Brobecker <brobecker@adacore.com>) * exceptions.h (enum_errors) <UNDEFINED_COMMAND_ERROR>: New enum. * mi/mi-parse.c (mi_parse): Throw UNDEFINED_COMMAND_ERROR instead of a regular error when the GDB/MI command does not exist. * mi/mi-main.c (mi_cmd_list_features): Add "undefined-command-error-code".

2013-08-20fix PR python/15816Tom Tromey1-4/+7
This fixes PR python/15816. The bug here is that python-selftest.exp can fail: No symbol "RETURN_MASK_ALL" in current context. RETURN_MASK_ALL is a macro, so if macros do not end up in the debuginfo (very typical) then the test fails. It seemed simplest to me to simply turn the RETURN_MASK_ defines into enum constants. This way they end up in the debuginfo and all is well. PR python/15816: * exceptions.h (return_mask): Now an enum. (RETURN_MASK_QUIT, RETURN_MASK_ERROR, RETURN_MASK_ALL): Now enum constants.

2013-07-01Constify main.c:get_init_files.Pedro Alves1-0/+6
A following patch will want to make the "gdbinit" global array const. As usual, that forces in a cascading series of const additions. This patch preemptively does those. I went all the way up to constifying catch_command_errors, but then that would require constifying execute_command as well (which is a much more significant effort). So as stop point, I found the cleanest would be to add a variant of catch_command_errors that takes const args, and use that in the few spots that needed it due to the the get_init_files constification. gdb/ 2013-07-01 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (source_script): Make 'file' parameter const. * cli/cli-cmds.h (source_script): Likewise. * exceptions.c (catch_command_errors_const): New function. * exceptions.h (catch_command_errors_const): Declare. * main.c (get_init_files): Make parameters const, and adjust.
