2019-07-09Rename common to gdbsupportTom Tromey6-11/+11
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-07-03pipe command completerPedro Alves1-9/+83
This commit adds a completer for the "pipe" command. It can complete "pipe"'s options, and the specified GDB command. To make the completer aware of the "-d" option, this converts the option processing to use gdb::option.

2019-07-03Teach gdb::option about string optionsPedro Alves2-0/+107
A following patch will make the "pipe" command use the gdb::option framework for option processing. However, "pipe"'s only option today is a string option, "-d DELIM", and gdb::option does not support string options yet. This commit adds support for string options, mapped to var_string. For now, a string is parsed up until the first whitespace. I imagine that we'll need to add support for quoting so that we could do: (gdb) cmd -option 'some -string' without gdb confusing the "-string" for an option. This doesn't seem important for pipe, so I'm leaving it for another day. One thing I'm not happy with, is that the string data is managed as a raw malloc-allocated char *, which means that we need to xfree it manually. This is because var_string settings work that way too. Although with var_string settings we're leaking the strings at gdb exit, that was never really a problem. For options though, leaking is undesirable. I think we should tackle that for both settings and options at the same time, so for now I'm just managing the malloced data manually. It's a bit ugly in option_def_and_value, but at least that's hidden from view. For testing, this adds a new "-string" option to "maint test-settings", and then tweaks gdb.base/options.exp to exercise it. gdb/ChangeLog: 2019-07-03 Pedro Alves <palves@redhat.com> * cli/cli-option.c (union option_value) <string>: New field.

2019-07-03Make gdb::option::complete_options save processed arguments tooPedro Alves2-30/+47
Currently, gdb::option::complete_options just discards any processed option argument, because no completer needs that data. When completing "pipe -d XXX gdbcmd XXX" however, the completer needs to know about -d's argument (XXX), in order to know where input is already past the gdb command and the delimiter. In this commit, the fix for that is the factoring out of the save_option_value_in_ctx function and calling it in complete_options. For testing, this makes "maint show test-options-completion-result" show the processed options too, like what the "maint test-options" subcommands output when run. Then, of course, gdb.base/options.exp is adjusted. Doing this exposed a couple latent bugs, which is what the other gdb changes in the patch are for: - in the var_enum case, without the change, we'd end up with a null enum argument, and print: "-enum (null)" - The get_ulongest change is necessary to avoid advancing PP in a case where we end up throwing an error, e.g., when parsing "11x". Without the change the operand pointer shown by "maint show test-options-completion-result" would be left pointing at "x" instead of "11x". gdb/ChangeLog: 2019-07-03 Pedro Alves <palves@redhat.com> * cli/cli-option.c (parse_option) <var_enum>: Don't return an option_value with a null enumeration.

2019-07-03Introduce the "with" commandPedro Alves4-41/+187
( See original discussion and prototype here: https://sourceware.org/ml/gdb-patches/2019-05/msg00570.html ) (gdb) help with Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING. Usage: with SETTING [VALUE] [-- COMMAND] Usage: w SETTING [VALUE] [-- COMMAND] With no COMMAND, repeats the last executed command. SETTING is any setting you can change with the "set" subcommands. E.g.: with language pascal -- print obj with print elements unlimited -- print obj As can be seen above, the "with" command is just like "set", but instead of setting the setting permanently, it sets the setting, runs a command and then restores the setting. (gdb) p g_s $1 = {a = 1, b = 2, c = 3} (gdb) with language ada -- print g_s $2 = (a => 1, b => 2, c => 3) Warning: the current language does not match this frame. (gdb) show language The current source language is "auto; currently c". (gdb) with print elements 100 -- with print object on -- print 1 $3 = 1 You can shorten things a bit though, as long as unambiguous. So this: (gdb) with print elements 100 -- with print object off -- print 1 is the same as: (gdb) w p el 100 -- w p o 0 -- p 1 Note that the patch adds a "w" alias for "with", as "w" is not currently taken: (gdb) w Ambiguous command "w": watch, wh, whatis, where, while, while-stepping, winheight, ws. Let me know if you'd prefer to reserve "w" for one of the other commands above. IMHO, this command will end up being used frequently enough that it deserves the "w" shorthand. A nice feature is that this is fully integrated with TAB-completion: (gdb) with p[TAB] pagination print prompt python (gdb) with print [TAB] address max-depth static-members array max-symbolic-offset symbol array-indexes null-stop symbol-filename asm-demangle object symbol-loading demangle pascal_static-members thread-events elements pretty type entry-values raw union frame-arguments repeats vtbl inferior-events sevenbit-strings (gdb) with print [TAB] (gdb) with print elements unlimited -- thread apply all -[TAB] -ascending -c -q -s (gdb) with print elements unlimited -- print -[TAB] -address -max-depth -repeats -vtbl -array -null-stop -static-members -array-indexes -object -symbol -elements -pretty -union The main advantage of this new command compared to command options, like the new "print -OPT", is that this command works with any setting, and, it works nicely when you want to override a setting while running a user-defined command, like: (gdb) with print pretty -- usercmd The disadvantage is that it isn't as compact or easy to type. I think of command options and this command as complementary. I think that even with this new command, it makes sense to continue developing the command options in the direction of exposing most-oft-used settings as command options. Inspired by Philippe's "/" command proposal, if no command is specified, then the last command is re-invoked, under the overridden setting: (gdb) p g_s $1 = {a = 1, b = 2, c = 3} (gdb) with language ada $2 = (a => 1, b => 2, c => 3) Warning: the current language does not match this frame. Note: "with" requires "--" to separate the setting from the command. It might be possible to do without that, but, I haven't tried it yet, and I think that this can go in without it. We can always downgrade to making "--" optional if we manage to make it work. On to the patch itself, the implementation of the command is simpler than one might expect. A few details: - I factored out a bit from pipe_command into repeat_previous directly, because otherwise I'd need to copy&paste the same code and same error message in the with command. - The parse_cli_var_uinteger / parse_cli_var_zuinteger_unlimited / do_set_command changes are necessary since we can now pass an empty string as argument. - do_show_command was split in two, as a FIXME comment suggests, but for a different reason: we need to get a string version of a "set" command's value, and we already had code for that in do_show_command. That code is now factored out to the new get_setshow_command_value_string function. - There's a new "maint with" command added too: (gdb) help maint with Like "with", but works with "maintenance set" variables. Usage: maintenance with SETTING [VALUE] [-- COMMAND] With no COMMAND, repeats the last executed command. SETTING is any setting you can change with the "maintenance set" subcommands. "with" and "maint with" share 99% of the implementation. This might be useful on its own, but it's also useful for testing, since with this, we can use the "maint set/show test-settings" settings for exercising the "with" machinery with all the command type variants (all enum var_types). This is done in the new gdb/base/with.exp testcase. The documentation bits are originally based on Philippe's docs for the "/" command, hence the attribution in the ChangeLog. gdb/ChangeLog: 2019-07-03 Pedro Alves <palves@redhat.com> * NEWS (New commands): Mention "with" and "maint with". * cli/cli-cmds.c (with_command_1, with_command_completer_1) (with_command, with_command_completer): New.

alias_command does not detect that the prefixes of the alias command and the aliased command are not matching: it is comparing the alias prefix with itself, instead of comparing it with the aliased command prefix. This causes either the alias command to silently do nothing, or to have GDB asserting: (gdb) alias assigne imprime limite-elements = set print elements ../../binutils-gdb/gdb/cli/cli-cmds.c:1552: internal-error: void alias_command(const char*, int): Assertion `c_command != NULL && c_command != (struct cmd_list_element *) -1' failed.

2019-06-13Delete parse_flags/parse_flags_qcsPedro Alves2-86/+0
Now that "thread/frame apply" have been converted to the gdb::option framework, these functions are no longer used. For a while, I thought about keeping the unit tests, by making a local version of parse_flags_qcs in the unit tests file. But all that would really test that is used by GDB itself, is the validate_flags_qcs function. So in the end, I went through all the unit tests, and converted any that wasn't already covered to gdb.base/options.exp tests. And those have all already been added in previous patches. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * cli/cli-utils.c (parse_flags, parse_flags_qcs): Delete. * cli/cli-utils.h (parse_flags, parse_flags_qcs): Delete. * unittests/cli-utils-selftests.c (test_parse_flags) (test_parse_flags_qcs): Delete.

2019-06-13Make "frame apply" support -OPT optionsPedro Alves2-6/+22
This adds support for '-'-style options to the "frame apply" family of commands -- "frame apply COUNT", "frame apply level", "frame apply all", "faas" and "tfaas". The -q/-c/-s flags were already supported, -past-main/-past-entry is new: ~~~ (gdb) help frame apply all Apply a command to all frames. Usage: frame apply all [OPTION]... COMMAND Prints the frame location information followed by COMMAND output. By default, an error raised during the execution of COMMAND aborts "frame apply". Options: -q Disables printing the frame location information. -c Print any error raised by COMMAND and continue. -s Silently ignore any errors or empty output produced by COMMAND. -past-main [on|off] Set whether backtraces should continue past "main". Normally the caller of "main" is not of interest, so GDB will terminate the backtrace at "main". Set this if you need to see the rest of the stack trace. -past-entry [on|off] Set whether backtraces should continue past the entry point of a program. Normally there are no callers beyond the entry point of a program, so GDB will terminate the backtrace there. Set this if you need to see the rest of the stack trace. ~~~ TAB completion of options is now supported. Also, TAB completion of COMMAND in "frame apply all COMMAND" does the right thing now, making use of complete_command, added by the previous patch. E.g.: (gdb) thread apply all -ascending frame apply all -past-main print -[TAB] -address -elements -pretty -symbol -array -null-stop -repeats -union -array-indexes -object -static-members -vtbl (gdb) thread apply all -ascending frame apply all -past-main print glo[TAB] global1 global2 The change to tfaas_command is necessary because otherwise you get this: (gdb) tfaas -- Unrecognized option at: frame apply all -s -- That's because the above is equivalent to: (gdb) thread apply all -s frame apply all -s -- and the "--" instructs "thread apply" to consider everything up to "--" as its command options. And from that view, "frame" is an invalid option.

2019-06-13"set print raw frame-arguments" -> "set print raw-frame-arguments"Pedro Alves1-2/+6
A following patch will introduce options for the "backtrace" command, based on some "set print" and "set backtrace" settings. There's one setting in particular that is a bit annoying if we want to describe the backtrace options and the settings commands using the same data structures: "set print raw frame-arguments" The problem is that space between "raw" and "frame-arguments". Calling the option "bt -raw frame-arguments" would be odd. So I'm calling the option "bt -raw-frame-arguments" instead. And for consistency, this patch renames the set/show commands to: "set print raw-frame-arguments" "show print raw-frame-arguments" I.e., dash instead of space. The old commands are left in place, but marked deprecated. We need to adjust a couple testcases, because the relevant tests use gdb_test_no_output and the old commands are no longer silent: (gdb) set print raw frame-arguments on Warning: command 'set print raw frame-arguments' is deprecated. Use 'set print raw-frame-arguments'. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * NEWS (Changed commands): Mention set/show print raw-frame-arguments, and that "set/show print raw frame-arguments" are now deprecated. * cli/cli-decode.c (add_setshow_boolean_cmd): Now returns the command. * command.h (add_setshow_boolean_cmd): Return cmd_list_element *. * stack.c (_initialize_stack): Install "set/show print raw-frame-arguments", and deprecate "set/show print raw frame-arguments". * valprint.c (_initialize_valprint): Deprecate "set/show print raw". gdb/doc/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.texinfo (Print Settings): Document "set/show print raw-frame-arguments" instead of "set/show print raw frame-arguments". gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.guile/scm-frame-args.exp: Use "set print raw-frame-arguments" instead of "set print raw frame-arguments". * gdb.python/py-frame-args.exp: Likewise.
2019-06-13Introduce generic command options frameworkPedro Alves8-118/+1326
This commit adds a generic command options framework, that makes it easy enough to add '-'-style options to commands in a uniform way, instead of each command implementing option parsing in its own way. Options are defined in arrays of option_def objects (for option definition), and the same options definitions are used for supporting TAB completion, and also for generating the relevant help fragment of the "help" command. See the gdb::options::build_help function, which returns a string with the result of replacing %OPTIONS% in a template string with an auto-generated "help" string fragment for all the passed-in options. Since most options in GDB are in the form of "-OPT", with a single dash, this is the format that the framework supports. I like to think of gdb's "-OPT" as the equivalent to getopt's long options format ("--OPT"), and gdb's "/" as the equivalent to getopt's short options format. getopt's short options format allows mixing several one-character options, like "ls -als", kind of similar to gdb's "x /FMT" and "disassemble /MOD", etc. While with gdb's "-" options, the option is expected to have a full name, and to be abbreviatable. E.g., "watch -location", "break -function main", etc. This patch only deals with "-" options. The above comment serves more to disclose why I don't think we should support mixing several unrelated options in a single "-" option invocation, like "thread apply -qcs" instead of "thread apply -q -c -s". The following patches will add uses of the infrastructure to several key commands. Most notably, "print", "compile print", "backtrace", "frame apply" and "thread apply". I tried to add options to several commands in order to make sure the framework didn't leave that many open holes open. Options use the same type as set commands -- enum var_types. So boolean options are var_boolean, enum options are var_enum, etc. The idea is to share code between settings commands and command options. The "print" options will be based on the "set print" commands, and their names will be the same. Actually, their definitions will be the same too. There is a function to create "set/show" commands from an array for option definitions: /* Install set/show commands for options defined in OPTIONS. DATA is a pointer to the structure that holds the data associated with the OPTIONS array. */ extern void add_setshow_cmds_for_options (command_class cmd_class, void *data, gdb::array_view<const option_def> options, struct cmd_list_element **set_list, struct cmd_list_element **show_list); That will be used by several following patches. Other features: - You can use the "--" delimiter to explicitly indicate end of options. Several existing commands use this token sequence for this effect already, so this just standardizes it. - You can shorten option names, as long as unambiguous. Currently, some commands allow this (e.g., break -function), while others do not (thread apply all -ascending). As GDB allows abbreviating command names and other things, it feels more GDB-ish to allow abbreviating option names too, to me. - For boolean options, 0/1 stands for off/on, just like with boolean "set" commands. - For boolean options, "true" is implied, just like with boolean "set commands. These are the option types supported, with a few examples: - boolean options (var_boolean). The option's argument is optional. (gdb) print -pretty on -- *obj (gdb) print -pretty off -- *obj (gdb) print -p -- *obj (gdb) print -p 0 -- *obj - flag options (like var_boolean, but no option argument (on/off)) (gdb) thread apply all -s COMMAND - enum options (var_enum) (gdb) bt -entry-values compact (gdb) bt -e c - uinteger options (var_uinteger) (gdb) print -elements 100 -- *obj (gdb) print -e 100 -- *obj (gdb) print -elements unlimited -- *obj (gdb) print -e u -- *obj - zuinteger-unlimited options (var_zuinteger_unlimited) (gdb) print -max-depth 100 -- obj (gdb) print -max-depth -1 -- obj (gdb) print -max-depth unlimited -- obj Other var_types could be supported, of course. These were just the types that I needed for the commands that I ported over, in the following patches. It was interesting (and unfortunate) to find that we need at least 3 different modes to cover the existing commands: - Commands that require ending options with "--" if you specify any option: "print" and "compile print". - Commands that do not want to require "--", and want to error out if you specify an unknown option (i.e., an unknown argument that starts with '-'): "compile code" / "compile file". - Commands that do not want to require "--", and want to process unknown options themselves: "bt", because of "bt -COUNT", "thread/frame apply", because "-" is a valid command. The different behavior is encoded in the process_options_mode enum, passed to process_options/complete_options. For testing, this patch adds one representative maintenance command for each of the process_options_mode values, that are used by the testsuite to exercise the options framework: (gdb) maint test-options require-delimiter (gdb) maint test-options unknown-is-error (gdb) maint test-options unknown-is-operand and adds another command to help with TAB-completion testing: (gdb) maint show test-options-completion-result See their description at the top of the maint-test-options.c file.

2019-06-13Remove "show" command completers, "set" command completers for string commandsPedro Alves1-1/+13
The default command completer is symbol_completer, but it makes no sense for a "show" command to complete on symbols, or anything else, really. I wonder whether we should instead make the default be no completer. That seems like a much larger/complicated audit/change, so I'd like to move forward with this version, as it'll be covered by tests. I noticed this because a following patch will add a new gdb.base/settings.exp testcase that exercises all sorts of details of settings commands, including completing the show commands, using new representative "maint test-settings <type or settings command>" commands.

2019-05-17Add debug redirect optionAlan Hayward3-14/+47
Currently, when logging is enabled, output will be sent to both a logfile and standard terminal output. The redirect option sends output only to the logfile. This includes all debug output. Add the option to redirect debug output seperately to normal output, using the cli command: set logging debugredirect on By setting this and enabling logging, all output and debug will be sent to the logfile. The user will still see all output but no debug output. This causes a change in behaviour for anyone currently using logging redirect, as now only output will be redirected. Users will have to issue the additional command above to also redirect debug. Expand ui-redirect.exp cover the changes. gdb/ChangeLog: * cli/cli-interp.c (struct saved_output_files): Add saved entry. (cli_interp_base::set_logging): Check debug_redirect. * cli/cli-interp.h (set_logging): Add debug_redirect parameter. * cli/cli-logging.c (debug_redirect): Add static variable. (pop_output_files): Add default param. (handle_redirections): Print debug setting. (show_logging_command): Likewise.

2019-05-17Change file close behavior for tee_fileAlan Hayward3-47/+22
Instead of using two bools to decide if the files should close when tee_file is closed, make file one stay open and file two close. This simplifies the use cases for it. Inline the make_logging_output into the calling functions (the logic here looks ugly in order to simplify a later change). Expand ui-redirect.exp to cover the changes, similar to mi-logging.exp. gdb/ChangeLog: * cli/cli-interp.c (cli_interp_base::set_logging): Create tee_file directly. * cli/cli-interp.h (make_logging_output): Remove declaration. * cli/cli-logging.c (make_logging_output): Remove function. * mi/mi-interp.c (mi_interp::set_logging): Create tee_file directly. * ui-file.c (tee_file::tee_file): Remove bools.

2019-04-25Make exception handling more efficientTom Tromey1-2/+2
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.

2019-04-08Replace throw_exception with throw in some casesTom Tromey1-1/+1
This replaces throw_exception with "throw;" when possible. This was written by script. The rule that is followed is that uses of the form: catch (... &name) { ... throw_exception (name); } ... can be rewritten.

2019-03-05Remove excess calls to gdb_flushTom Tromey2-15/+4
A customer noticed some mildly odd MI output, where CLI output was split into multiple MI strings at unusual boundaries, like this: ~"$1 = (b => true" ~", p => 0x407260" This is technically correct according to the MI spec, but still unusual, in that there's no particular reason for the string to be split where it is. I tracked this down to a call to gdb_flush in generic_val_print. Then, I went through all calls to gdb_flush and removed the ones I thought were superfluous. In particular: * Any call in the value-printing code; * Likewise the type-printing code (just a single call); and * Any call that immediately followed a printf that obviously ended with a newline, my belief being that gdb's standard output streams are line buffered (by inheriting the behavior from stdio) Regression tested on x86-64 Fedora 29. I didn't add a new test case. I tend to think we don't necessarily want to specify this behavior in the tests.

2019-02-19Fix error message and use-after-free on errors in nested sourced filesSimon Marchi1-3/+4
Errors that happen in nested sourced files (when a sourced file sources another file) lead to a wrong error message, or use-after-free. For example, if I put this in "a.gdb": command_that_doesnt_exist and this in "b.gdb": source a.gdb and try to "source b.gdb" in GDB, the result may look like this: (gdb) source b.gdb b.gdb:1: Error in sourced command file: _that_doesnt_exist:1: Error in sourced command file: Undefined command: "command_that_doesnt_exist". Try "help". Notice the wrong file name where "a.gdb" should be. The exact result may differ, depending on the feelings of the memory allocator. What happens is: - The "source a.gdb" command is saved by command_line_append_input_line in command_line_input's static buffer. - Since we are sourcing a file, the script_from_file function stores the script name (a.gdb) in the source_file_name global. However, it doesn't do a copy, it just saves a pointer to command_line_input's static buffer. - The "command_that_doesnt_exist" command is saved by command_line_append_input_line in command_line_input's static buffer. Depending on what xrealloc does, source_file_name may now point to freed memory, or at the minimum the data it was pointing to was overwritten. - When the error is handled in script_from_file, we dererence source_file_name to print the name of the file in which the error occured. To fix it, I made source_file_name an std::string, so that keeps a copy of the file name instead of pointing to a buffer with a too small lifetime. With this patch, the expected filename is printed, and no use-after-free occurs: (gdb) source b.gdb b.gdb:1: Error in sourced command file: a.gdb:1: Error in sourced command file: Undefined command: "command_that_doesnt_exist". Try "help". I passed explicit template parameters to make_scoped_restore (<std::string, const std::string &>), so that the second parameter is passed by reference and avoid a copy. It was not as obvious as I first thought to change gdb.base/source.exp to test this, because source commands inside sourced files are interpreted relative to GDB's current working directory, not the directory of the currently sourced file. As a workaround, I moved the snippet that tests errors after the snippet that adds the source directory to the search path. This way, the "source source-error-1.gdb" line in source-error.exp manages to find the file. For reference, here is what ASAN reports when use-after-free occurs: (gdb) source b.gdb ================================================================= ==18498==ERROR: AddressSanitizer:

2019-02-07Normalize include guards in gdbTom Tromey7-21/+22
While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom

2019-01-12Implement help/show values for 'set|show style'.Philippe Waroquiers2-54/+61
Currently, the behaviour is: (gdb) show style (gdb) set style (gdb) show style address (gdb) set style address (gdb) With this patch, the behaviour is: (gdb) show style style address background: The "address" background color is: none style address foreground: The "address" foreground color is: blue style address intensity: The "address" display intensity is: normal enabled: CLI output styling is enabled. style filename background: The "filename" background color is: none style filename foreground: The "filename" foreground color is: green style filename intensity: The "filename" display intensity is: normal style function background: The "function" background color is: none style function foreground: The "function" foreground color is: yellow style function intensity: The "function" display intensity is: normal style variable background: The "variable" background color is: none style variable foreground: The "variable" foreground color is: cyan style variable intensity: The "variable" display intensity is: normal (gdb) set style "set style" must be followed by an appropriate subcommand. List of set style subcommands: set style address -- Address display styling set style enabled -- Set whether CLI styling is enabled set style filename -- Filename display styling set style function -- Function name display styling set style variable -- Variable name display styling Type "help set style" followed by set style subcommand name for full documentation. Type "apropos word" to search for commands related to "word". Command name abbreviations are allowed if unambiguous. (gdb) show style address background: The "filename" background color is: none foreground: The "filename" foreground color is: green intensity: The "filename" display intensity is: normal (gdb) set style address List of set style address subcommands: set style address background -- Set the background color for this property set style address foreground -- Set the foreground color for this property set style address intensity -- Set the display intensity color for this property Type "help set style address" followed by set style address subcommand name for full documentation. Type "apropos word" to search for commands related to "word". Command name abbreviations are allowed if unambiguous. (gdb) gdb/ChangeLog * cli/cli-style.h (class cli_style_option): <add_setshow_commands> Remove arg prefixname, add do_set and do_show. Add member functions set_list and show_list. * cli/cli-style.c (class cli_style_option): Update accordingly. (style_set_list): Move to file scope. (style_show_list): Likewise. (set_style): Call help_list. (show_style): Call cmd_show_list. (_initialize_cli_style): New macro STYLE_ADD_SETSHOW_COMMANDS. Update to use the new macro.
2019-01-09gdb: Avoid signed integer overflow when printing source linesAndrew Burgess1-19/+16
When printing source lines with calls to print_source_lines we need to pass a start line number and an end line number. The end line number is calculated by calling get_lines_to_list and adding this value to the start line number. For example this code from list_command: print_source_lines (cursal.symtab, first, first + get_lines_to_list (), 0); The problem is that get_lines_to_list returns a value based on the GDB setting `set listsize LISTSIZE`. By default LISTSIZE is 10, however, its also possible to set LISTSIZE to unlimited, in which case get_lines_to_list will return INT_MAX. As the parameter signature for print_source_lines is: void print_source_lines (struct symtab *, int, int, print_source_lines_flags); and `first` in the above code is an `int`, then when LISTSIZE is `unlimited` the above code will result in signed integer overflow, which is undefined. The solution in this patch is a new class source_lines_range that can be constructed from a single line number and a direction (forward or backward). The range is then constructed from the line number and the value of get_lines_to_list. gdb/ChangeLog: * cli/cli-cmds.c (list_command): Pass a source_lines_range to print_source_lines. * source.c (print_source_lines_base): Update line number check. (print_source_lines): New function. (source_lines_range::source_lines_range): New function. * source.h (class source_lines_range): New class. (print_source_lines): New declaration.
2019-01-01Update copyright year range in all GDB files.Joel Brobecker16-16/+16
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.
2018-12-30Fix 'help set/show style' strange layouts/results.Philippe Waroquiers1-5/+5
The layout for 'help set address|variable' is strange, e.g.: (gdb) help set style address style address List of show Address display styling Configure address colors and display intensity subcommands: show Address display styling Configure address colors and display intensity background -- Set the background color for this property show Address display styling Configure address colors and display intensity foreground -- Set the foreground color for this property show Address display styling Configure address colors and display intensity intensity -- Set the display intensity color for this property Type "help show Address display styling Configure address colors and display intensity" followed by show Address display styling Configure address colors and display intensity subcommand name for full documentation. Type "apropos word" to search for commands related to "word". Command name abbreviations are allowed if unambiguous. (gdb) The help for 'set style function|filename' gives help for 'Show': (gdb) help set style filename Filename display styling Configure filename colors and display intensity. List of show style filename subcommands: show style filename background -- Set the background color for this property show style filename foreground -- Set the foreground color for this property show style filename intensity -- Set the display intensity color for this property The help for 'show style function|filename' is equally strange, as it speaks about commands, instead of sub commands: (gdb) help show style filename Filename display styling Configure filename colors and display intensity. List of commands: background -- Show the background color for this property foreground -- Show the foreground color for this property intensity -- Show the display intensity color for this property Type "help" followed by command name for full documentation. Type "apropos word" to search for commands related to "word". Command name abbreviations are allowed if unambiguous. (gdb) This patch fixes all this. Note that the 'set style' and 'show style' have the same prefix_doc: (gdb) help show style Style-specific settings Configure various style-related variables, such as colors ... (gdb) help set style Style-specific settings Configure various style-related variables, such as colors ... Other similar commands (such as set|show history) have typically a more specific prefix: (gdb) help show history Generic command for showing command history parameters. ... (gdb) help set history Generic command for setting command history parameters. ... This could be fixed by having set_prefix_doc and show_prefix_doc instead of the single prefix_doc argument to cli_style_option::add_setshow_commands. That could be improved if deemed better. 2018-12-29 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-style.c (cli_style_option::add_setshow_commands): Initialize m_set_prefix with "set", instead of re-assigning m_show_prefix. Use m_set_prefix for set_list and m_show_prefix for show_list. (_initialize_cli_style): Correct the order of arguments in variable_name_style.add_setshow_commands and address_style.add_setshow_commands calls.
