git-related mistake (added the files to the index, but forgot to
commit --amend them before pushing the commit)
|

This patch adds documentation for the new GDB/MI commands "-catch-assert"
and "-catch-exception", meant to provide the same functionality as
the "catch assert", "catch exception" and "catch exception unhandled"
CLI commands.
In the GDB Manual, there was already a section for catchpoint comments,
so that seemed like a natural place to document the new commands. But
commands related to a given concept seem to have traditionally been
organized alphabetically, and I didn't want future commands to break
down logical pairing of various commands. For instance, "-catch-load"
and "-catch-unload" are quite "distant" from each other, and it is easy
to imagine a new comment which would alphabetically fall in between,
causing them to be separated. So I introduced subsections to prevent
that from happening.
gdb/ChangeLog:
* NEWS: Add entry documenting the new "-catch-assert" and
"-catch-exception" GDB/MI commands.
gdb/doc/ChangeLog:
* gdb.texinfo (Shared Library GDB/MI Catchpoint Commands):
New subsection inside which the "-catch-load" and "-catch-unload"
commands documentation is now placed.
(Ada Exception GDB/MI Catchpoint Commands): New subsection
documenting the "-catch-assert" and "-catch-exception" new
GDB/MI commands.
|
|
... in place of the CLI "catch ..." commands. The latter were used
because the GDB/MI equivalents were not available at the time.
gdb/testsuite/ChangeLog:
* gdb.ada/mi_catch_ex.exp: Adjusts all "catch ..." tests to
use the appropriate GDB/MI command instead, and verify
the test output.
|
|
This patch introduces two new GDB/MI commands implementing the equivalent
of the "catch exception" and "catch assert" GDB/CLI commands.
gdb/ChangeLog:
* breakpoint.h (init_ada_exception_breakpoint): Add parameter
"enabled".
* breakpoint.c (init_ada_exception_breakpoint): Add parameter
"enabled". Set B->ENABLE_STATE accordingly.
* ada-lang.h (ada_exception_catchpoint_kind): Move here from
ada-lang.c.
(create_ada_exception_catchpoint): Add declaration.
* ada-lang.c (ada_exception_catchpoint_kind): Move to ada-lang.h.
(create_ada_exception_catchpoint): Make non-static. Add new
parameter "disabled". Use it in call to
init_ada_exception_breakpoint.
(catch_ada_exception_command): Add parameter "enabled" in call
to create_ada_exception_catchpoint.
(catch_assert_command): Likewise.
* mi/mi-cmds.h (mi_cmd_catch_assert, mi_cmd_catch_exception):
Add declarations.
* mi/mi-cmds.c (mi_cmds): Add the "catch-assert" and
"catch-exception" commands.
* mi/mi-cmd-catch.c: Add #include "ada-lang.h".
(mi_cmd_catch_assert, mi_cmd_catch_exception): New functions.
|
|
This is in preparation for making that type public, in order to be
able to use make create_ada_exception_catchpoint public as well,
making it usable from the GDB/MI implementation.
gdb/ChangeLog:
* ada-lang.c (enum ada_exception_catchpoint_kind): Renames
"enum exception_catchpoint_kind". Replace the "ex_" prefix
of all its enumerates with "ada_". Update the rest of this
file throughout.
|
|
This patch reworks a bit how the different steps required to insert
an Ada exception catchpoints are organized. They used to be:
1. Call a "decode" function which does:
1.a. Parse the command and its arguments
1.b. Create a SAL & OPS from some of those arguments
2. Call create_ada_exception_catchpoint using SAL as well
as some of the arguments extracted above.
The bulk of the change consists in integrating step (1.b) into
step (2) in order to turn create_ada_exception_catchpoint into
a function whose arguments are all user-level concepts. This
paves the way from a straightforward implementation of the equivalent
commands in the GDB/MI interpreter.
gdb/ChangeLog:
* ada-lang.c (ada_decode_exception_location): Delete.
(create_ada_exception_catchpoint): Remove arguments "sal",
"addr_string" and "ops". Add argument "ex_kind" instead.
Adjust implementation accordingly, calling ada_exception_sal
to get the entities it no longer gets passed as arguments.
Document the function's arguments.
(catch_ada_exception_command): Use catch_ada_exception_command_split
instead of ada_decode_exception_location, and update call to
create_ada_exception_catchpoint.
(catch_ada_assert_command_split): Renames
ada_decode_assert_location. Remove parameters "addr_string" and
"ops", and now returns void. Adjust implementation accordingly.
Update the function documentation.
(catch_assert_command): Use catch_ada_assert_command_split
instead of ada_decode_assert_location. Update call to
create_ada_exception_catchpoint.

Consider the following example:
% gdb -q -batch -ex 'source nonexistant-file'
[nothing]
One would have at least expected the debugger to warn about
not finding the file, similar to the error shown when using
a more interactive mode. Eg:
(gdb) source nonexistant-file
nonexistant-file: No such file or directory.
Not raising an error appears to be intentional, presumably in order
to prevent this situation from stoping the execution of a GDB script.
But the lack of at least a warning makes it harder for a user to
diagnose any issue, if the file was expected to be there and readable.
This patch adds a warning in that case:
% gdb -q -batch -ex 'source nonexistant-file'
warning: nonexistant-file: No such file or directory.
gdb/ChangeLog:
* utils.h (perror_warning_with_name): Add declaration.
* utils.c (perror_warning_with_name): New function.
* cli/cli-cmds.c (source_script_with_search): Add call to
perror_warning_with_name if from_tty is nul.
gdb/testsuite/ChangeLog:
* gdb.base/source-nofile.gdb: New file.
* gdb.base/source.exp: Add two tests verifying the behavior when
the "source" command is given a non-existant filename.
|
|
The main purpose of this patch is to extract the part of
throw_perror_with_name that computes a string providing the system
error message combined with a prefix string. This will become useful
later on to provide a routine which prints a warning using that
perror_string, rather than throwing an error.
gdb/ChangeLog:
* utils.c (perror_string): New function, extracted out of
throw_perror_with_name.
(throw_perror_with_name): Rework to use perror_string.

This patch renames the "set/show remotebaud" commands into
"set/show serial baud", and moves its implementation into serial.c.
It also moves the "baud_rate" global from top.c to serial.c, where
the new code is being added (the alternative was to add an include
of target.h).
And to facilitate the transition to the new setting name, this
patch also preserves the old commands, and marks them as deprecated
to alert the users of the change.
gdb/ChangeLog:
* cli/cli-cmds.c (show_baud_rate): Moved to serial.c as
serial_baud_show_cmd.
(_initialize_cli_cmds): Delete the code creating the
"set/show remotebaud" commands.
* serial.c (baud_rate): Move here from top.c.
(serial_baud_show_cmd): Move here from cli/cli-cmds.c.
(_initialize_serial): Create "set/show serial baud" commands.
Add "set/show remotebaud" command aliases.
* top.c (baud_rate): Moved to serial.c.
* NEWS: Document the new "set/show serial baud" commands,
replacing "set/show remotebaud".
gdb/doc/ChangeLog:
* gdb.texinfo: Replace "set remotebaud" and "show remotebaud"
by "set serial baud" and "show serial baud" (resp) throughout.

target_read_memory & friends build on top of target_read (thus on top
of the target_xfer machinery), but turn all errors to EIO, an errno
value. I think we'd better convert all these to return a
target_xfer_error too, like target_xfer_partial in a previous patch.
The patch starts by doing that.
(The patch does not add a enum target_xfer_error value for '0'/no
error, and likewise does not change the return type of several of
these functions to enum target_xfer_error, because different functions
return '0' with different semantics.)
I audited the tree for memory_error calls, EIO checks, places where
GDB hardcodes 'errno = EIO', and also for strerror calls. What I
found is that nowadays there's really no need to handle random errno
values, other than the EIOs gdb itself hardcodes. No doubt errno
values would appear in common code back in the day when
target_xfer_memory was the main interface to access memory, but
nowadays, any errno value that deprecated interface could return is
just absorved by default_xfer_partial:
else if (xfered == 0 && errno == 0)
/* "deprecated_xfer_memory" uses 0, cross checked against
ERRNO as one indication of an error. */
return 0;
else
return -1;
There are two places in the code that check for EIO and print "out of
bounds", and defer to strerror for other errors. That's
c-lang.c:c_get_string, and valprint.c.:val_print_string. AFAICT, the
strerror branch can never be reached nowadays, as the only error
possible to get at those points is EIO, given that it's GDB itself
that set that errno value (in target_read_memory, etc.).
breakpoint.c:insert_bp_location always prints the error val as if an
errno, returned by target_insert_breakpoint, with strerr. Now the
error here is either always EIO for mem-break.c targets (again
hardcoded by the target_read_memory/target_write_memory functions), so
this always prints "Input/output error" or similar (depending on
host), or, for remote targets (and probably others), this gem:
Error accessing memory address 0x80200400: Unknown error -1.
This patch makes these 3 places print the exact same error
memory_error prints. This changes output, but I think this is better,
for making memory error output consistent with other commands, and, it
means we have a central place to tweak for memory errors.
E.g., this changes:
Cannot insert breakpoint 1.
Error accessing memory address 0x5fc660: Input/output error.
to:
Cannot insert breakpoint 1.
Cannot access memory at address 0x5fc660
Which I find pretty much acceptable.
Surprisingly, only py-prettyprint.exp had a regression, for needing an
adjustment. I also grepped the testsuite for the old errors, and
found no other hits.
Now that errno values aren't used anywhere in any of these memory
access related routines, I made memory_error itself take a
target_xfer_error instead of an errno. The new
target_xfer_memory_error function added recently is no longer
necessary, and is thus removed.
Tested on x86_64 Fedora 17, native and gdbserver.
