2019-10-01Remove the ui_out_style_kind enumTom Tromey1-1/+2
This removes the ui_out_style_kind enum, in favor of simply using ui_file_style references. This simplifies the code somewhat. gdb/ChangeLog 2019-10-01 Tom Tromey <tom@tromey.com> * ui-out.h (enum class ui_out_style_kind): Remove.

2019-09-17gdb: Look for compilation directory relative to directory search pathMike Gulick1-11/+58
The 'directory' command allows the user to provide a list of filesystem directories in which to search for source code. The directories in this search path are used as the base directory for the source filename from the debug information (DW_AT_name). Thus the directory search path provides alternatives to the existing compilation directory from the debug information (DW_AT_comp_dir). Generally speaking, DW_AT_name stores the filename argument passed to the compiler (including any directory components), and DW_AT_comp_dir stores the current working directory from which the compiler was executed. For example: $ cd /path/to/project/subdir1 $ gcc -c a/test.c -g The corresponding debug information will look like this: DW_AT_name : a/test.c DW_AT_comp_dir : /path/to/project/subdir1 When compiling with the -fdebug-prefix-map GCC option, the compilation directory can be arbitrarily rewritten. In the above example, we may rewrite the compilation directory as follows: $ gcc -c a/test.c -g -fdebug-prefix-map=/path/to/project= In this case, the corresponding debug information will look like: DW_AT_name : a/test.c DW_AT_comp_dir : /subdir1 This prevents GDB from finding the corresponding source code based on the debug information alone. In some cases, a substitute-path command can be used to re-map a consistent prefix in the rewritten compilation directory to the real filesystem path. However, there may not be a consistent prefix remaining in the debug symbols (for example in a project that has source code in many subdirectories under the project's root), thereby requiring multiple substitute-path rules. In this case, it is easier to add the missing prefix to the directory search path via the 'directory' command. The function find_and_open_source currently searches in: SEARCH_PATH/FILENAME where SEARCH_PATH corresponds to each individual entry in the directory search path (which is guaranteed to contain the compilation directory from the debug information, as well as the current working directory). FILENAME corresponds to the source filename (DW_AT_name), which may have directory components in it. In addition, GDB searches in: SEARCH_PATH/FILE_BASENAME where FILE_BASENAME is the basename of the DW_AT_name entry. This change modifies find_and_open_source to additionally search in: SEARCH_PATH/COMP_DIR/FILENAME where COMP_DIR is the compilation directory from the debug symbols. In the example given earlier, running: (gdb) directory /path/to/project will now allow GDB to correctly locate the source code from the debug information. gdb/ChangeLog: * source.c (prepare_path_for_appending): New function. (openp): Make use of new function. (find_and_open_source): Search for the compilation directory and source file as a relative path beneath the directory search path. gdb/doc/ChangeLog: * gdb.texinfo (Source Path): Additional text to better describe how the source path directory list is used when searching for source files. gdb/testsuite/ChangeLog: * gdb.base/source-dir.exp: Add extra test for mapped compilation directory.
2019-08-07Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers1-3/+7
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. 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.

2019-08-06Clean up source file error reportingTom Tromey1-14/+12
print_source_lines_base reopens the source file every time that a source line is to be printed. However, there's no need to do this so frequently -- it's enough to do it when switching source files, and otherwise rely on the cache. The code seems to try to avoid these multiple opens; at a guess I'd say something just got confused along the way. This patch fixes the problem by reorganizing the code both to make it more clear, and to ensure that reopens only occur when the "last source visited" changes. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * source.c (last_source_error): Now bool. (print_source_lines_base): Make "noprint" bool. Only open source file when last_source_visited changes.
2019-08-06Add file offsets to the source cacheTom Tromey1-102/+18
Currently, gdb stores the number of lines and an array of file offsets for the start of each line in struct symtab. This patch moves this information to the source cache. This has two benefits. First, it allows gdb to read a source file less frequently. Currently, a source file may be read multiple times: once when computing the file offsets, once when highlighting, and then pieces may be read again while printing source lines. With this change, the file is read once for its source text and file offsets; and then perhaps read again if it is evicted from the cache. Second, if multiple symtabs cover the same source file, then this will share the file offsets between them. I'm not sure whether this happens in practice. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * annotate.c (annotate_source_line): Use g_source_cache. * source-cache.c (source_cache::get_plain_source_lines): Change parameters.

2019-07-09Rename common to gdbsupportTom Tromey1-4/+4
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. *

2019-06-15gdb: Remove an update of current_source_line and current_source_symtabAndrew Burgess1-25/+2
While reviewing some of the annotation code I noticed that identify_source_line (in source.c) sets current_source_line, current_source_symtab, and also calls clear_lines_listed_range. This seems a little strange, identify_source_line is really a wrapper around annotate_source, and is only called when annotation_level is greater than 0 (so annotations are turned on). It seems weird (to me) that when annotations are on we update GDB's idea of the "current" line/symtab, but when they are off we don't, given that annotations are really about communicating GDB's state to a user (GUI) and surely shouldn't be changing GDB's behaviour. This commit removes from identify_source_line all of the setting of current line/symtab and the call to clear_lines_listed_range, after doing this GDB still passes all tests, so I don't believe these lines were actually required. With this code removed identify_source_line is only a wrapper around annotate_source, so I moved identify_source_line to annotate.c and renamed it to annotate_source_line. gdb/ChangeLog: * annotate.c: Add 'source.h' and 'objfiles.h' includes. (annotate_source): Make static. (annotate_source_line): Moved from source.c and renamed from identify_source_line. Update the return type. * annotate.h (annotate_source): Delete declaration. (annotate_source_line): Declaration moved from source.h, and renamed from identify_source_line. Return type updated. * source.c (identify_source_line): Moved to annotate.c and renamed to annotate_source_line. (info_line_command): Remove check of annotation_level. * source.h (identify_source_line): Move declaration to annotate.h and rename to annotate_source_line. * stack.c: Add 'annotate.h' include. (print_frame_info): Remove check of annotation_level before calling annotate_source_line.
2019-06-15gdb: New function to open source file and compute line charpos dataAndrew Burgess1-17/+16

There should be no user visible changes after this commit. gdb/ChangeLog: * source-cache.c (source_cache::get_plain_source_lines): Use open_source_file_with_line_charpos instead of just open_source_file, remove call to find_source_lines. (source_cache::get_source_lines): Likewise. * source.c (find_source_lines): Make static. (get_filename_and_charpos): Renamed into... (open_source_file_with_line_charpos): ..this along with changes to return a scoped_fd, and some other minor clean ups. (identify_source_line): Use open_source_file_with_line_charpos. (search_command_helper): Use open_source_file_with_line_charpos instead of just open_source_file, remove call to find_source_lines. * source.h (open_source_file_with_line_charpos): Declare new function. (find_source_lines): Delete declaration.

(identify_source_line): Update call to get_filename_and_charpos.
2019-06-14Only compute realpath when basenames_may_differ is setTom Tromey1-5/+9
A user noted that, when sources are symlinked, gdb annotations will print the real path, rather than the name of the symlink. It seems to me that it is better to print the name of the file that was actually used in the build, unless there is some reason not to. This patch implements this, with the caveat that it will not work when basenames-may-differ is enabled. The way this mode is currently implemented, returning the symbolic (not real) path is not possible. While I think it would be good to redo the source file name cache and perhaps integrate it with class source_cache, I haven't done so here. Regression tested on x86-64 Fedora 29. gdb/ChangeLog 2019-06-14 Tom Tromey <tromey@adacore.com> * source.c (find_and_open_source): Respect basenames_may_differ. gdb/testsuite/ChangeLog 2019-06-14 Tom Tromey <tromey@adacore.com> * gdb.base/annotate-symlink.exp: New file.
2019-06-06Apply substitute-path to relative filenames as wellРуслан Ижбулатов1-9/+4
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.

2019-04-19Fix "list" when control characters are seenTom Tromey1-2/+6
PR symtab/24423 points out that control characters in a source file cause a hang in the "list" command, a regression introduced by the styling changes. This patch, from the PR, fixes the bug. I've included a minimal change to the "list" test that exercises this code. I recall that this bug was discussed on gdb-patches, and I thought there was a patch there as well, but I was unable to find it. gdb/ChangeLog 2019-04-19 Ilya Yu. Malakhov <malakhov@mcst.ru> PR symtab/24423: * source.c (print_source_lines_base): Advance "iter" when a control character is seen. gdb/testsuite/ChangeLog 2019-04-19 Tom Tromey <tromey@adacore.com> PR symtab/24423: * gdb.base/list0.h (foo): Add a control-l character.
2019-02-17Fix pager bugs with style outputTom Tromey1-22/+40
I believe this fixes all the pager output problems with styling that Philippe pointed out, plus at least one more. The patch is somewhat hard to reason about, so you may wish to give it a try. Even writing the tests was hard. This removes the style caching, because it was difficult to keep the style cache correct in all cases. Since this would cause more style escapes to be emitted, instead it changes fputs_styled to try to avoid unnecessary changes. Another bug was that the wrap buffer was not flushed in the case where wrap_column==0. In the old (pre-patch series) code, characters were directly emitted in this case; so flushing the wrap buffer here restores this behavior. On error the wrap buffer must be emptied. Otherwise, interrupting output can leave characters in the buffer that will be emitted later. As discussed on gdb-patches, this fixes the ada-lang.c problem where filtered and unfiltered printing were mixed. Now user_select_syms uses filtered printing, which is what its callees were already doing. Finally, it was possible for source line highlighting to be garbled (and invalid escape sequences emitted) if the pager was invoked at the wrong spot. To fix this, the patch arranges for source line escapes to always be emitted as a unit. gdb/ChangeLog 2019-02-17 Tom Tromey <tom@tromey.com> * ada-lang.c (user_select_syms): Use filtered printing. * utils.c (wrap_style): New global.

2019-01-09gdb: Avoid signed integer overflow when printing source linesAndrew Burgess1-7/+41
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.
2019-01-08gdb: Move declarations from symtab.h to source.hAndrew Burgess1-24/+6
Declarations for functions in source.c are split between source.h and symtab.h. This commit moves the small number that are in symtab.h into source.h.

2019-01-08gdb: Handle requests to print source lines backwardAndrew Burgess1-1/+11
...by which I mean from high line number to low, not, actually backward character by character! Commit: commit 62f29fda90cf1d5a1899f57ef78452471c707fd6 Date: Tue Oct 9 22:21:05 2018 -0600 Highlight source code using GNU Source Highlight introduced a regression in the test gdb.linespec/explicit.exp, in which a request is made to GDB to print a reverse sequence of lines, from +10 to -10 from the current line number. The expected behaviour is that GDB prints nothing. The above commit changed this so that GDB now prints: Line number 32 out of range; /path/to/gdb/testsuite/gdb.linespec/explicit.c has 71 lines. which is a little confusing. This commit fixes the regression, and restores the behaviour that GDB prints nothing. While I was passing I noticed a call to `back` on a std::string that I was concerned could be empty if the request for source lines returns an empty string. I don't know if it would be possible for a request for lines to return an empty string, I guess it should be impossible, in which case, maybe this should be an assertion, but adding a `empty` check, seems like an easy and cheap safety net. gdb/ChangeLog: * source.c (print_source_lines_base): Handle requests to print reverse line number sequences, and guard against empty lines string.
2019-01-08gdb: Fix skip of `\r` before `\n` in source outputAndrew Burgess1-6/+1

This caused a regression on the test gdb.fortran/nested-funcs.exp, which happens to have `\r\n` line endings. gdb/ChangeLog: * source.c (print_source_lines_base): Fix skip of '\r' if next character is '\n'.

2018-12-28Add output styles to gdbTom Tromey1-1/+2
This adds some output styling to the CLI. A style is currently a foreground color, a background color, and an intensity (dim or bold). (This list could be expanded depending on terminal capabilities.) A style can be applied while printing. For ui-out, this is done by passing the style constant as an argument. For low-level cases, fprintf_styled and fputs_styled are provided. Users can control the style via a number of new set/show commands. In the interest of not typing many nearly-identical documentation strings, I automated this. On the down side, this is not very i18n-friendly. I've chose some default colors to use. I think it would be good to enable this by default, so that when users start the new gdb, they will see the new feature. Stylizing is done if TERM is set and is not "dumb". This could be improved when the TUI is available by using the curses has_colors call. That is, the lowest layer could call this without committing to using curses everywhere; see my other patch for TUI colorizing. I considered adding a new "set_style" method to ui_file. However, because the implementation had to interact with the pager code, I didn't take this approach. But, one idea might be to put the isatty check there and then have it defer to the lower layers. gdb/ChangeLog 2018-12-28 Tom Tromey <tom@tromey.com> * utils.h (set_output_style, fprintf_styled) (fputs_styled): Declare. * utils.c (applied_style, desired_style): New globals.

Recently, the xmalloc above was replaced with a xrealloc, because as can be seen above, that 'buf' variable above was a static local, otherwise we'd be leaking. This commit replaces that and the associated manual buffer growing with a gdb::def_vector<char>. I don't think there's much point in reusing the buffer across command invocations. While doing this, I realized that reverse_search_command is almost identical to forward_search_command. So this commit factors out a common helper function instead of duplicating a lot of code. There are some tests for "forward-search" in gdb.base/list.exp, but since they use the "search" alias, they were a bit harder to find than expected. That's now fixed, both by testing both variants, and by adding some commentary. Also, there are no tests for the "reverse-search" command, so this commit adds some for that too. gdb/ChangeLog: 2018-12-08 Pedro Alves <palves@redhat.com> * source.c (forward_search_command): Rename to ...

2018-11-05Fix 4K leak in open_source_file each time next/step changes of function.Philippe Waroquiers1-1/+2
When current function changes after a next/step, GDB shows a message such as: (gdb) s info_fun1 () at /bd/home/philippe/gdb/git/build_smallthing/gdb/testsuite/../../../smallthing/gdb/testsuite/gdb.base/info_qt.c:41 41 info_qt_inc++; (gdb) Valgrind reports a 4K definite leak for each such message (full stacktrace of the leak below). This patch fixes this leak, by transferring the current s->fullname to the unique_xmalloc_ptr fullname given to find_and_open_source. Note that I do not understand why find_and_open_source always tries to re-execute the substitution rules on the provided fullname, as source.c symtab_to_fullname just blindly returns a non NULL s->fullname, counting on forget_cached_source_info to be called if search dir or substitution rules are changed. Similarly, psymtab_to_fullname also just returns a non NULL ps->fullname. ==15309== VALGRIND_GDB_ERROR_BEGIN ==15309== 69,632 bytes in 17 blocks are definitely lost in loss record 3,158 of 3,186 ==15309== at 0x4C2BE2D: malloc (vg_replace_malloc.c:299) ==15309== by 0x5BF0987: realpath@@GLIBC_2.3 (canonicalize.c:78) ==15309== by 0x41F713: gdb_realpath(char const*) (pathstuff.c:72) ==15309== by 0x608833: openp(char const*, enum_flags<openp_flag>, char const*, int, std::unique_ptr<char, gdb::xfree_deleter<char> >*) (source.c:861) ==15309== by 0x608B89: find_and_open_source(char const*, char const*, std::unique_ptr<char, gdb::xfree_deleter<char> >*) (source.c:1049) ==15309== by 0x608D0B: open_source_file(symtab*) (source.c:1074) ==15309== by 0x609101: print_source_lines_base(symtab*, int, int, enum_flags<print_source_lines_flag>) (source.c:1291) ==15309== by 0x614ADF: print_frame_info(frame_info*, int, print_what, int, int) (stack.c:911) ==15309== by 0x614C45: print_stack_frame(frame_info*, int, print_what, int) (stack.c:181) ==15309== by 0x511D5E: print_stop_location (infrun.c:8044) ==15309== by 0x511D5E: print_stop_event(ui_out*) (infrun.c:8061) ==15309== by 0x40DD6D: cli_on_normal_stop(bpstats*, int) (cli-interp.c:145) ==15309== by 0x512409: operator() (functional:2127) ==15309== by 0x512409: notify (observable.h:106) ==15309== by 0x512409: normal_stop() (infrun.c:8334) ==15309== by 0x5156D8: fetch_inferior_event(void*) (infrun.c:3955) ==15309== by 0x4B3EEC: gdb_wait_for_event(int) (event-loop.c:859) ==15309== by 0x4B3FF6: gdb_do_one_event() [clone .part.4] (event-loop.c:322) ==15309== by 0x4B41B4: gdb_do_one_event (common-exceptions.h:219) ==15309== by 0x4B41B4: start_event_loop() (event-loop.c:371) ==15309== by 0x551217: captured_command_loop() (main.c:330) ==15309== by 0x55220C: captured_main (main.c:1177) ==15309== by 0x55220C: gdb_main(captured_main_args*) (main.c:1193) ==15309== by 0x29B4F7: main (gdb.c:32) ==15309== ==15309== VALGRIND_GDB_ERROR_END gdb/ChangeLog 2018-11-04 Philippe Waroquiers <philippe.waroquiers@skynet.be> * source.c (open_source_file): Fix leak by transferring the current s->fullname to the unique_xmalloc_ptr fullname given to find_and_open_source.

2018-02-28Make gdbserver work with filename-only binariesSergio Durigan Junior1-34/+0
Simon mentioned on IRC that, after the startup-with-shell feature has been implemented on gdbserver, it is not possible to specify a filename-only binary, like: $ gdbserver :1234 a.out /bin/bash: line 0: exec: a.out: not found During startup program exited with code 127. Exiting This happens on systems where the current directory "." is not listed in the PATH environment variable. Although including "." in the PATH variable is a possible workaround, this can be considered a regression because before startup-with-shell it was possible to use only the filename (due to reason that gdbserver used "exec*" directly). The idea of the patch is to verify if the program path provided by the user (or by the remote protocol) contains a directory separator character. If it doesn't, it means we're dealing with a filename-only binary, so we call "gdb_abspath" to properly expand it and transform it into a full path. Otherwise, we leave the program path untouched. This mimicks the behaviour seen on GDB (look at "openp" and "attach_inferior", for example). I am also submitting a testcase which exercises the scenario described above. This test requires gdbserver to be executed in a different CWD than the original, so I also created a helper function, "with_cwd" (on testsuite/lib/gdb.exp), which takes care of cd'ing into and out of the specified dir. Built and regtested on BuildBot, without regressions. gdb/ChangeLog: 2018-02-28 Sergio Durigan Junior <sergiodj@redhat.com> Simon Marchi <simon.marchi@polymtl.ca> * common/common-utils.c: Include "sys/stat.h".

2018-02-28Create new common/pathstuff.[ch]Sergio Durigan Junior1-0/+1
This commit moves the path manipulation routines found on utils.c to a new common/pathstuff.c, and updates the Makefile.in's accordingly. The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and "gdb_abspath". This will be needed because gdbserver will have to call "gdb_abspath" on my next patch, which implements a way to expand the path of the inferior provided by the user in order to allow specifying just the binary name when starting gdbserver, like: $ gdbserver :1234 a.out With the recent addition of the startup-with-shell feature on gdbserver, this scenario doesn't work anymore if the user doesn't have the current directory listed in the PATH variable. I had to do a minor adjustment on "gdb_abspath" because we don't have access to "tilde_expand" on gdbserver, so now the function is using "gdb_tilde_expand" instead. Otherwise, the code is the same.
