Руслан Ижбулатов	4fa0265ede	Apply substitute-path to relative filenames as well When source file path is relative to the build directory (which is considered a good practice and is enforced in certain buildsystems, such as meson), gdb only applies substitute-path to the build directory path. Then gdb appends the source file path to the rewritten build directory path, and tries to access that. This fails if either two of the following conditions are true: a) The user didn't specify substitute-path for the build directory. This is highly likely, since path substitution for build directories is not documented anywhere, and since gdb does not tell[0] the user the path to the build directory, just the source file path. b) The source file path changed. This can also easily happen, since a source path that is relative to the build directory can include any number of directory names that are not part of the program source tree (starting with the name of the root directory of the source tree). Gdb will not apply substitute-path to that relative path, thus there is no way for the user to tell gdb about these changes. This commit changes the code to apply substitute-path to all filenames, both relative and absolute. This way it is possible to do things like: set substitute-path ../foobar-1.0 /src/my/foobar-1.0 which is completely in line with the user expectations. This might break unusual cases where build directory path is also relative (is that even possible?) and happens to match the path to the source directory (i.e. happens to match a substitution rule). [0]: There's a "maintenance info symtabs" command that does show the names of the build directories, but normal users are not required to know or use that. gdb/ChangeLog 2019-06-06 Руслан Ижбулатов <lrn1986@gmail.com> * source.c (find_and_open_source): Also rewrite relative file names.	8 years ago

Tom Tromey	3847a7bfbf	Add timestamps to "maint time" output Currently "maint time" will print the amount of time a command took. Sometimes, though, it's useful to have a timestamp as well -- for example if one is correlating a gdb log with some other log. This patch adds a timestamp to the start and end of each command when this setting is in effect. This also removes a "//" comment and changes scoped_command_stats to use DISABLE_COPY_AND_ASSIGN; two minor things I noticed while working on the patch.

Sudakshina Das	237df8fe18	[BFD, AArch64] Fix PT_GNU_PROPERTY alignment issue If the new GNU property section was being created by the linker (this will happen only if none of the inputs have any GNU property section but the command line to the linker forces a bti with --force-bti), the alignment of the section and hence the program header of PT_GNU_PROPERTY type was not being set correctly.

Pedro Alves	b02f78f928	Introduce and use make_unique_xstrdup Adds an utility function to make it shorter to write the common case of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it throughout. Note: I tried to put this in common/common-utils.h near skip_spaces, etc. but that is included in common/common-defs.h before common/gdb_unique_ptr.h is included, so it would fail to compile because gdb::unique_xmalloc_ptr isn't defined at that point yet.

Philippe Waroquiers	66d8c86285	Improve usability and/or readibility of help and apropos output. The "help" command can output long list of command names or classes. Use the title style to style the command names or classes to make the output more readable. Similarly, change "apropos" command to also style the command names. It is sometimes unclear why "apropos REGEXP" lists some commands, and then the user has to manually do 'help command' for all commands listed by "apropos" to see more details about the matching commands. => Add an optional flag -v so that "apropos -v REGEXP": * outputs the full documentation of matching commands. * highlights the documentation parts matching REGEXP.	7 years ago
Philippe Waroquiers	9303eb2fb1	Add highlight style, title style, fputs_highlighted. Improve 'show style' Have 'show style' and its subcommands using a style to style its output. This allows the GDB user or developer to use 'show style' to visually see with one command how all the current styles look like. Add 2 new styles highlight style, title style and fputs_highlighted function. Highlight style is used by fputs_highlighted to highlight the parts of its char *STR argument that match a HIGHLIGHT regexp. This (and the title style) will be used in a following patch.	7 years ago

Philippe Waroquiers	947d39462e	Implement \| (pipe) command. The pipe command allows to run a GDB command, and pipe its output to a shell command: (gdb) help pipe Send the output of a gdb command to a shell command. Usage: \| [COMMAND] \| SHELL_COMMAND Usage: \| -d DELIM COMMAND DELIM SHELL_COMMAND Usage: pipe [COMMAND] \| SHELL_COMMAND Usage: pipe -d DELIM COMMAND DELIM SHELL_COMMAND Executes COMMAND and sends its output to SHELL_COMMAND. The -d option indicates to use the string DELIM to separate COMMAND from SHELL_COMMAND, in alternative to \|. This is useful in case COMMAND contains a \| character. With no COMMAND, repeat the last executed command and send its output to SHELL_COMMAND. (gdb) For example: (gdb) pipe print some_data_structure \| grep -B3 -A3 something The pipe character is defined as an alias for pipe command, so that the above can be typed as: (gdb) \| print some_data_structure \| grep -B3 -A3 something If no GDB COMMAND is given, then the previous command is relaunched, and its output is sent to the given SHELL_COMMAND. This also defines convenience vars $_shell_exitcode and $_shell_exitsignal to record the exit code and exit signal of the last shell command launched by GDB e.g. by "shell", "pipe", ... gdb/ChangeLog 2019-05-31 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-cmds.c (pipe_command): New function. (_initialize_cli_cmds): Call add_com for pipe_command. Define \| as an alias for pipe. (exit_status_set_internal_vars): New function. (shell_escape): Call exit_status_set_internal_vars. cli/cli-decode.c (find_command_name_length): Recognize \| as a single character command.	7 years ago
Philippe Waroquiers	b8fd091888	Add function execute_command_to_ui_file 2019-05-31 Philippe Waroquiers <philippe.waroquiers@skynet.be> * gdbcmd.h (execute_command_to_ui_file): New declaration. top.c (execute_command_to_ui_file): New function, mostly a copy of execute_command_to_string. (execute_command_to_string): Implement by calling execute_command_to_ui_file.	7 years ago
Philippe Waroquiers	68bb5386b8	Add previous_saved_command_line to allow a command to repeat a previous command. Currently, a previous command can be repeated when the user types an empty line. This is implemented in handle_line_of_input by returning saved_command_line in case an empty line has been input. If we want a command to repeat the previous command, we need to save the previous saved_command_line, as when a command runs, the saved_command_line already contains the current command line of the command being executed. As suggested by Tom, the previous_saved_command_line is made static. At the same time, saved_command_line is also made static. The support functions/variables for the repeat command logic are now all located inside top.c. gdb/ChangeLog 2019-05-31 Philippe Waroquiers <philippe.waroquiers@skynet.be> * top.h (saved_command_line): Remove declaration. * top.c (previous_saved_command_line, previous_repeat_arguments): New variables. (saved_command_line): Make static, define together with other 'repeat variables'. (dont_repeat): Clear repeat_arguments. (repeat_previous, get_saved_command_line, save_command_line): New functions. (gdb_init): Initialize saved_command_line and previous_saved_command_line. * main.c (captured_main_1): Remove saved_command_line initialization. * event-top.c (handle_line_of_input): Update to use the new 'repeat' related functions instead of direct access to saved_command_line. * command.h (repeat_previous, get_saved_command_line, save_command_line): New declarations. (dont_repeat): Add comment.	7 years ago
Jose E. Marchesi	a0486bac41	libctf: fix a number of build problems found on Solaris and NetBSD - Use of nonportable <endian.h> - Use of qsort_r - Use of zlib without appropriate magic to pull in the binutils zlib - Use of off64_t without checking (fixed by dropping the unused fields that need off64_t entirely) - signedness problems due to long being too short a type on 32-bit platforms: ctf_id_t is now 'unsigned long', and CTF_ERR must be used only for functions that return ctf_id_t - One lingering use of bzero() and of <sys/errno.h> All fixed, using code from gnulib where possible.
