* GDB: Allow arbitrary keywords in integer set commandsMaciej W. Rozycki2023-01-191-20/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than just `unlimited' allow the integer set commands (or command options) to define arbitrary keywords for the user to use, removing hardcoded arrangements for the `unlimited' keyword. Remove the confusingly named `var_zinteger', `var_zuinteger' and `var_zuinteger_unlimited' `set'/`show' command variable types redefining them in terms of `var_uinteger', `var_integer' and `var_pinteger', which have the range of [0;UINT_MAX], [INT_MIN;INT_MAX], and [0;INT_MAX] each. Following existing practice `var_pinteger' allows extra negative values to be used, however unlike `var_zuinteger_unlimited' any number of such values can be defined rather than just `-1'. The "p" in `var_pinteger' stands for "positive", for the lack of a more appropriate unambiguous letter, even though 0 obviously is not positive; "n" would be confusing as to whether it stands for "non-negative" or "negative". Add a new structure, `literal_def', the entries of which define extra keywords allowed for a command and numerical values they correspond to. Those values are not verified against the basic range supported by the underlying variable type, allowing extra values to be allowed outside that range, which may or may not be individually made visible to the user. An optional value translation is possible with the structure to follow the existing practice for some commands where user-entered 0 is internally translated to UINT_MAX or INT_MAX. Such translation can now be arbitrary. Literals defined by this structure are automatically used for completion as necessary. So for example: const literal_def integer_unlimited_literals[] = { { "unlimited", INT_MAX, 0 }, { nullptr } }; defines an extra `unlimited' keyword and a user-visible 0 value, both of which get translated to INT_MAX for the setting to be used with. Similarly: const literal_def zuinteger_unlimited_literals[] = { { "unlimited", -1, -1 }, { nullptr } }; defines the same keyword and a corresponding user-visible -1 value that is used for the requested setting. If the last member were omitted (or set to `{}') here, then only the keyword would be allowed for the user to enter and while -1 would still be used internally trying to enter it as a part of a command would result in an "integer -1 out of range" error. Use said error message in all cases (citing the invalid value requested) replacing "only -1 is allowed to set as unlimited" previously used for `var_zuinteger_unlimited' settings only rather than propagating it to `var_pinteger' type. It could only be used for the specific case where a single extra `unlimited' keyword was defined standing for -1 and the use of numeric equivalents is discouraged anyway as it is for historical reasons only that they expose GDB internals, confusingly different across variable types. Similarly update the "must be >= -1" Guile error message. Redefine Guile and Python parameter types in terms of the new variable types and interpret extra keywords as Scheme keywords and Python strings used to communicate corresponding parameter values. Do not add a new PARAM_INTEGER Guile parameter type, however do handle the `var_integer' variable type now, permitting existing parameters defined by GDB proper, such as `listsize', to be accessed from Scheme code. With these changes in place it should be trivial for a Scheme or Python programmer to expand the syntax of the `make-parameter' command and the `gdb.Parameter' class initializer to have arbitrary extra literals along with their internal representation supplied. Update the testsuite accordingly. Approved-By: Simon Marchi <simon.marchi@efficios.com>

* gdb: add string_file::release methodSimon Marchi2022-01-261-2/+1
| | | | | | | | | | | | | | | | A common pattern for string_file is to want to move out the internal string buffer, because it is the result of the computation that we want to return. It is the reason why string_file::string returns a non-const reference, as explained in the comment. I think it would make sense to have a dedicated method for that instead and make string_file::string return a const reference. This allows removing the explicit std::move in the typical case. Note that compile_program::compute was missing a move, meaning that the resulting string was copied. With the new version, it's not possible to forget to move.

* Use filtered output in some dumping commandsTom Tromey2022-01-051-16/+16
| | | | | | | | | | | | | | There are several commands that may optionally send their output to a file -- they take an optional filename argument and open a file. This patch changes these commands to use filtered output. The rationale here is that, when printing to gdb_stdout, filtering is appropriate -- it is, and should be, the default for all commands. And, when writing to a file, paging will not happen anyway (it only happens when the stream==gdb_stdout), so using the _filtered form will not change anything.

* gdb: make string-like set show commands use std::string variableSimon Marchi2021-10-031-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | String-like settings (var_string, var_filename, var_optional_filename, var_string_noescape) currently take a pointer to a `char *` storage variable (typically global) that holds the setting's value. I'd like to "mordernize" this by changing them to use an std::string for storage. An obvious reason is that string operations on std::string are often easier to write than with C strings. And they avoid having to do any manual memory management. Another interesting reason is that, with `char *`, nullptr and an empty string often both have the same meaning of "no value". String settings are initially nullptr (unless initialized otherwise). But when doing "set foo" (where `foo` is a string setting), the setting now points to an empty string. For example, solib_search_path is nullptr at startup, but points to an empty string after doing "set solib-search-path". This leads to some code that needs to check for both to check for "no value". Or some code that converts back and forth between NULL and "" when getting or setting the value. I find this very error-prone, because it is very easy to forget one or the other. With std::string, we at least know that the variable is not "NULL". There is only one way of representing an empty string setting, that is with an empty string. I was wondering whether the distinction between NULL and "" would be important for some setting, but it doesn't seem so. If that ever happens, it would be more C++-y and self-descriptive to use optional<string> anyway. Actually, there's one spot where this distinction mattered, it's in init_history, for the test gdb.base/gdbinit-history.exp. init_history sets the history filename to the default ".gdb_history" if it sees that the setting was never set - if history_filename is nullptr. If history_filename is an empty string, it means the setting was explicitly cleared, so it leaves it as-is. With the change to std::string, this distinction doesn't exist anymore. This can be fixed by moving the code that chooses a good default value for history_filename to _initialize_top. This is ran before -ex commands are processed, so an -ex command can then clear that value if needed (what gdb.base/gdbinit-history.exp tests). Another small improvement, in my opinion is that we can now easily give string parameters initial values, by simply initializing the global variables, instead of xstrdup-ing it in the _initialize function. In Python and Guile, when registering a string-like parameter, we allocate (with new) an std::string that is owned by the param_smob (in Guile) and the parmpy_object (in Python) objects. This patch started by changing all relevant add_setshow_* commands to take an `std::string *` instead of a `char **` and fixing everything that failed to build. That includes of course all string setting variable and their uses. string_option_def now uses an std::string also, because there's a connection between options and settings (see add_setshow_cmds_for_options). The add_path function in source.c is really complex and twisted, I'd rather not try to change it to work on an std::string right now. Instead, I added an overload that copies the std:string to a `char *` and back. This means more copying, but this is not used in a hot path at all, so I think it is acceptable.

* gdb: generate the prefix name for prefix commands on demandMarco Barisione2021-05-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the prefixname field of struct cmd_list_element was manually set for prefix commands. This seems verbose and error prone as it required every single call to functions adding prefix commands to specify the prefix name while the same information can be easily generated. Historically, this was not possible as the prefix field was null for many commands, but this was fixed in commit 3f4d92ebdf7f848b5ccc9e8d8e8514c64fde1183 by Philippe Waroquiers, so we can rely on the prefix field being set when generating the prefix name. This commit also fixes a use after free in this scenario: * A command gets created via Python (using the gdb.Command class). The prefix name member is dynamically allocated. * An alias to the new command is created. The alias's prefixname is set to point to the prefixname for the original command with a direct assignment. * A new command with the same name as the Python command is created. * The object for the original Python command gets freed and its prefixname gets freed as well. * The alias is updated to point to the new command, but its prefixname is not updated so it keeps pointing to the freed one. gdb/ChangeLog: * command.h (add_prefix_cmd): Remove the prefixname argument as it can now be generated automatically. Update all callers. (add_basic_prefix_cmd): Ditto. (add_show_prefix_cmd): Ditto. (add_prefix_cmd_suppress_notification): Ditto.

Update all code reading the prefix name to use the method, and remove all code setting it. * python/py-cmd.c (cmdpy_destroyer): Remove code to free the prefixname member as it's now a method. (cmdpy_function): Determine if the command is a prefix by looking at prefixlist, not prefixname.

* Replace most calls to help_list and cmd_show_listTom Tromey2020-04-171-17/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are many prefix commands that do nothing but call either help_list or cmd_show_list. I happened to notice that one such call, for "set print type", used the wrong command list parameter, causing incorrect output. Rather than fix this bug in isolation, I decided to eliminate this possibility by adding two new ways to add prefix commands, which simply route the call to help_list or cmd_show_list, as appropriate. This makes it impossible for a mismatch to occur. In some cases, a bit of output was removed; however, I don't think this output in general was very useful. It seemed redundant with what's already printed by help_list. A representative example is this hunk, removed from ada-lang.c: - printf_unfiltered (_(\ -"\"set ada\" must be followed by the name of a setting.\n")); This simplified the CLI style set/show commands quite a bit, and allowed the deletion of a macro. This also cleans up some unusual code in windows-tdep.c. Tested on x86-64 Fedora 30. Note that I have no way to build the go32-nat.c change. gdb/ChangeLog 2020-04-17 Tom Tromey <tromey@adacore.com> * auto-load.c (show_auto_load_cmd): Remove.

I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

* Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers2019-08-071-3/+1

Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

* Teach gdb::option about string optionsPedro Alves2019-07-031-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Make gdb::option::complete_options save processed arguments tooPedro Alves2019-07-031-46/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Introduce generic command options frameworkPedro Alves2019-06-131-0/+461
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.
