2022-05-30gdb/manual: Introduce location specsPedro Alves1-1/+1
The current "Specify Location" section of the GDB manual starts with: "Several @value{GDBN} commands accept arguments that specify a location of your program's code." And then, such commands are documented as taking a "location" argument. For example, here's a representative subset: @item break @var{location} @item clear @var{location} @item until @var{location} @item list @var{location} @item edit @var{location} @itemx info line @var{location} @item info macros @var{location} @item trace @var{location} @item info scope @var{location} @item maint agent @r{[}-at @var{location}@r{,}@r{]} @var{expression} The issue here is that "location" isn't really correct for most of these commands. Instead, the "location" argument is really a placeholder that represent an umbrella term for all of the "linespecs", "explicit location", and "address location" input formats. GDB parses these and then finds the actual code locations (plural) in the program that match. For example, a "location" specified like "-function func" will actually match all the code locations in the program that correspond to the address/file/lineno of all the functions named "func" in all the loaded programs and shared libraries of all the inferiors. A location specified like "-function func -label lab" matches all the addresses of C labels named "lab" in all functions named "func". Etc. This means that several of the commands that claim they accept a "location", actually end up working with multiple locations, and the manual doesn't explain that all that well. In some cases, the command will work with all the resolved locations. In other cases, the command aborts with an error if the location specification resolves to multiple locations in the program. In other cases, GDB just arbitrarily and silently picks whatever is the first resolved code location (which sounds like should be improved). To clarify this, I propose we use the term "Location Specification", with shorthand "locaction spec", when we're talking about the user input, the argument or arguments that is/are passed to commands to instruct GDB how to find locations of interest. This is distinct from the actual code locations in the program, which are what GDB finds based on the user-specified location spec. Then use "location specification or the shorter "location spec" thoughout instead of "location" when we're talking about the user input. Thus, this commit does the following: - renames the "Specify Location" section of the manual to "Location Specifications". - It then introduces the term "Location Specification", with corresponding shorthand "location spec", as something distinct from an actual code location in the program. It explains what a concrete code location is. It explains that a location specification may be incomplete, and that may match multiple code locations in the program, or no code location at all. It gives examples. Some pre-existing examples were moved from the "Set Breaks" section, and a few new ones that didn't exist yet were added. I think it is better to have these centralized in this "Location Specification" section, since all the other commands that accept a location spec have an xref that points there. - Goes through the manual, and where "@var{location}" was used for a command argument, updated it to say "@var{locspec}" instead. At the same time, tweaks the description of the affected commands to describe what happens when the location spec resolves to more than one location. Most commands just did not say anything about that. One command -- "maint agent -at @var{location}" -- currently says it accepts a "location", suggesting it can accept address and explicit locations too, but that's incorrect. In reality, it only accepts linespecs, so fix it accordingly. One MI command -- "-trace-find line" -- currently says it accepts a "line specification", but it can accept address and explicit locations too, so fix it accordingly. Special thanks goes to Eli Zaretskii for reviews and rewording suggestions. Change-Id: Ic42ad8565e79ca67bfebb22cbb4794ea816fd08b
2022-01-07gdb/doc: shorten some source lines, and prevent some line breaksAndrew Burgess1-13/+17
Building on the previous commit, this makes use of a trailing @ to split long @deffn lines in the guile.texi source file. This splitting doesn't change how the document is laid out by texinfo. I have also wrapped keyword and argument name pairs in @w{...} to prevent line breaks appearing between the two. I've currently only done this for the longer @deffn lines, where a line break is possible. This makes the @deffn lines much nicer to read in the generated pdf.
2022-01-07gdb/doc: Remove (...) around guile procedure names in @deffn linesAndrew Burgess1-4/+11
Most guile procedures in the guile.texi file are defined like: @deffn {Scheme Procedure} name arg1 arg2 arg3 But there are two places where we do this: @deffn {Scheme Procedure} (name arg1 arg2 arg3) Notice the added (...). Though this does represent how a procedure call is written in scheme, it's not the normal style throughout the manual. I also checked the 'info guile' info page to see how they wrote there declarations, and they use the first style too. The second style also has the drawback that index entries are added as '(name', and so they are grouped in the '(' section of the index, which is not very user friendly. In this commit I've changed the definitions of make-command and make-parameter to use the first style. The procedure declaration lines can get pretty long with all of the arguments, and this was true for both of the procedures I am changing in this commit. I have made use of a trailing '@' to split the deffn lines, and keep them under 80 characters in the texi source. This makes no difference to how the final document looks. Finally, our current style for keyword arguments, appears to be: [#:keyword-name argument-name] I don't really understand the reason for this, 'info guile' just seems to use: [#:keyword-name] which seems just as good to me. But I don't propose to change that just now. What I do notice though, is that sometimes, texinfo will place a line break between the keyword-name and the argument-name, for example, the pdf of make-command is: make-command name [#:invoke invoke] [#:command-class command-class] [#:completer-class completer] [#:prefix? prefix] [#:doc doc-string] Notice the line break after '#:command-class' and after '#:doc', neither of which are ideal. And so, for the two commands I am changing in this commit, I have made use of @w{...} to prevent line breaks between the keyword-name and the argument-name. Now the pdf looks like this: make-command name [#:invoke invoke] [#:command-class command-class] [#:completer-class completer] [#:prefix? prefix] [#:doc doc-string] Which seems much better. I'll probably update the other deffn lines at some point.

2021-07-28Guile: temporary breakpointsGeorge Barrett1-1/+15
Adds API to the Guile bindings for creating temporary breakpoints and querying whether an existing breakpoint object is temporary. This is effectively a transliteration of the Python implementation. It's worth noting that the added `is_temporary' flag is ignored in the watchpoint registration path. This replicates the behaviour of the Python implementation, but might be a bit surprising for users. gdb/ChangeLog: 2021-06-09 George Barrett <bob@bob131.so> * guile/scm-breakpoint.c (gdbscm_breakpoint_object::spec): Add is_temporary field.

2019-04-29gdb: Introduce 'print max-depth' featureAndrew Burgess1-0/+3
Introduce a new print setting max-depth which can be set with 'set print max-depth DEPTH'. The default value of DEPTH is 20, but this can also be set to unlimited. When GDB is printing a value containing nested structures GDB will stop descending at depth DEPTH. Here is a small example: typedef struct s1 { int a; } s1; typedef struct s2 { s1 b; } s2; typedef struct s3 { s2 c; } s3; typedef struct s4 { s3 d; } s4; s4 var = { { { { 3 } } } }; The following table shows how various depth settings affect printing of 'var': | Depth Setting | Result of 'p var' | |---------------+--------------------------------| | Unlimited | $1 = {d = {c = {b = {a = 3}}}} | | 4 | $1 = {d = {c = {b = {a = 3}}}} | | 3 | $1 = {d = {c = {b = {...}}}} | | 2 | $1 = {d = {c = {...}}} | | 1 | $1 = {d = {...}} | | 0 | $1 = {...} | Only structures, unions, and arrays are replaced in this way, scalars and strings are not replaced. The replacement is counted from the level at which you print, not from the top level of the structure. So, consider the above example and this GDB session: (gdb) set print max-depth 2 (gdb) p var $1 = {d = {c = {...}}} (gdb) p var.d $2 = {c = {b = {...}}} (gdb) p var.d.c $3 = {b = {a = 3}} Setting the max-depth to 2 doesn't prevent the user from exploring deeper into 'var' by asking for specific sub-fields to be printed. The motivation behind this feature is to try and give the user more control over how much is printed when examining large, complex data structures. The default max-depth of 20 means that there is a change in GDB's default behaviour. Someone printing a data structure with 20 levels of nesting will now see '{...}' instead of their data, they would need to adjust the max depth, or call print again naming a specific field in order to dig deeper into their data structure. If this is considered a problem then we could increase the default, or even make the default unlimited. This commit relies on the previous commit, which added a new field to the language structure, this new field was a string that contained the pattern that should be used when a structure/union/array is replaced in the output, this allows languages to use a syntax that is more appropriate, mostly this will be selecting the correct types of bracket '(...)' or '{...}', both of which are currently in use. This commit should have no impact on MI output, expressions are printed through the MI using -var-create and then -var-list-children. As each use of -var-list-children only ever displays a single level of an expression then the max-depth setting will have no impact. This commit also adds the max-depth mechanism to the scripting language pretty printers following basically the same rules as for the built in value printing. One quirk is that when printing a value using the display hint 'map', if the keys of the map are structs then GDB will hide the keys one depth level after it hides the values, this ensures that GDB produces output like this: $1 = map_object = {[{key1}] = {...}, [{key2}] = {...}} Instead of this less helpful output: $1 = map_object = {[{...}] = {...}, [{...}] = {...}} This is covered by the new tests in gdb.python/py-nested-maps.exp. gdb/ChangeLog: * cp-valprint.c (cp_print_value_fields): Allow an additional level of depth when printing anonymous structs or unions. * guile/scm-pretty-print.c (gdbscm_apply_val_pretty_printer): Don't print either the top-level value, or the children if the max-depth is exceeded.

2016-10-06Remove Java supportTom Tromey1-2/+2
This patch removes the Java support from gdb. gcj has not seen much development or use for years now, and was recently removed from GCC. This patch changes gdb to follow; in the unlikely event that there are still users using gcj, they can continue to use an older gdb to debug. Or, they can debug in C++ mode.

2016-01-13Per-inferior/Inferior-qualified thread IDsPedro Alves1-5/+6
This commit changes GDB to track thread numbers per-inferior. Then, if you're debugging multiple inferiors, GDB displays "inferior-num.thread-num" instead of just "thread-num" whenever it needs to display a thread: (gdb) info inferiors Num Description Executable 1 process 6022 /home/pedro/gdb/tests/threads * 2 process 6037 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame 1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running) 1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running) 1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running) 2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running) 2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running) * 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running) (gdb) ... (gdb) thread 1.1 [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] (gdb) ... etc. You can still use "thread NUM", in which case GDB infers you're referring to thread NUM of the current inferior. The $_thread convenience var and Python's InferiorThread.num attribute are remapped to the new per-inferior thread number. It's a backward compatibility break, but since it only matters when debugging multiple inferiors, I think it's worth doing. Because MI thread IDs need to be a single integer, we keep giving threads a global identifier, _in addition_ to the per-inferior number, and make MI always refer to the global thread IDs. IOW, nothing changes from a MI frontend's perspective. Similarly, since Python's Breakpoint.thread and Guile's breakpoint-thread/set-breakpoint-thread breakpoint methods need to work with integers, those are adjusted to work with global thread IDs too. Follow up patches will provide convenient means to access threads' global IDs. To avoid potencially confusing users (which also avoids updating much of the testsuite), if there's only one inferior and its ID is "1", IOW, the user hasn't done anything multi-process/inferior related, then the "INF." part of thread IDs is not shown. E.g,.: (gdb) info inferiors Num Description Executable * 1 process 15275 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) add-inferior Added inferior 2 (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * NEWS: Mention that thread IDs are now per inferior and global thread IDs. * Makefile.in (SFILES): Add tid-parse.c.

2014-05-30Add a TRY_CATCH to get_prev_frame_always to better manage errors during unwind.Andrew Burgess1-0/+3
https://sourceware.org/ml/gdb-patches/2014-05/msg00737.html Currently a MEMORY_ERROR raised during unwinding a frame will cause the unwind to stop with an error message, for example: (gdb) bt #0 breakpt () at amd64-invalid-stack-middle.c:27 #1 0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32 #2 0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38 #3 0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44 #4 0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50 Cannot access memory at address 0x2aaaaaab0000 However, frame #4 is marked as being the end of the stack unwind, so a subsequent request for the backtrace looses the error message, such as: (gdb) bt #0 breakpt () at amd64-invalid-stack-middle.c:27 #1 0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32 #2 0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38 #3 0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44 #4 0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50 When fetching the backtrace, or requesting the stack depth using the MI interface the situation is even worse, the first time a request is made we encounter the memory error and so the MI returns an error instead of the correct result, for example: (gdb) -stack-info-depth ^error,msg="Cannot access memory at address 0x2aaaaaab0000" Or, (gdb) -stack-list-frames ^error,msg="Cannot access memory at address 0x2aaaaaab0000" However, once one of these commands has been used gdb has, internally, walked the stack and figured that out that frame #4 is the bottom of the stack, so the second time an MI command is tried you'll get the "expected" result: (gdb) -stack-info-depth ^done,depth="5" Or, (gdb) -stack-list-frames ^done,stack=[frame={level="0", .. snip lots .. }] After this patch the MEMORY_ERROR encountered during the frame unwind is attached to frame #4 as the stop reason, and is displayed in the CLI each time the backtrace is requested. In the MI, catching the error means that the "expected" result is returned the first time the MI command is issued. So, from the CLI the results of the backtrace will be: (gdb) bt #0 breakpt () at amd64-invalid-stack-middle.c:27 #1 0x00000000004008f0 in func5 () at amd64-invalid-stack-middle.c:32 #2 0x0000000000400900 in func4 () at amd64-invalid-stack-middle.c:38 #3 0x0000000000400910 in func3 () at amd64-invalid-stack-middle.c:44 #4 0x0000000000400928 in func2 () at amd64-invalid-stack-middle.c:50 Backtrace stopped: Cannot access memory at address 0x2aaaaaab0000 Each and every time that the backtrace is requested, while the MI output will similarly be consistently: (gdb) -stack-info-depth ^done,depth="5" Or, (gdb) -stack-list-frames ^done,stack=[frame={level="0", .. snip lots .. }] gdb/ChangeLog: * frame.c (struct frame_info): Add stop_string field.
