PR python/16699: GDB Python command completion with overriden complete vs. completer class This PR came from a Red Hat bug that was filed recently. I checked and it still exists on HEAD, so here's a proposed fix. Although this is marked as a Python backend bug, this is really about the completion mechanism used by GDB. Since this code reminds me of my first attempt to make a good noodle, it took me quite some time to fix it in a non-intrusive way. The problem is triggered when one registers a completion method inside a class in a Python script, rather than registering the command using a completer class directly. For example, consider the following script: class MyFirstCommand(gdb.Command): def __init__(self): gdb.Command.__init__(self,'myfirstcommand',gdb.COMMAND_USER,gdb.COMPLETE_FILENAME) def invoke(self,argument,from_tty): raise gdb.GdbError('not implemented') class MySecondCommand(gdb.Command): def __init__(self): gdb.Command.__init__(self,'mysecondcommand',gdb.COMMAND_USER) def invoke(self,argument,from_tty): raise gdb.GdbError('not implemented') def complete(self,text,word): return gdb.COMPLETE_FILENAME MyFirstCommand () MySecondCommand () When one loads this into GDB and tries to complete filenames for both myfirstcommand and mysecondcommand, she gets: (gdb) myfirstcommand /hom<TAB> (gdb) myfirstcommand /home/ ^ ... (gdb) mysecondcommand /hom<TAB> (gdb) mysecondcommand /home ^ (The "^" marks the final position of the cursor after the TAB). So we see that myfirstcommand honors the COMPLETE_FILENAME class (as specified in the command creation), but mysecondcommand does not. After some investigation, I found that the problem lies with the set of word break characters that is used for each case. The set should be the same for both commands, but it is not. During the process of deciding which type of completion should be used, the code in gdb/completer.c:complete_line_internal analyses the command that requested the completion and tries to determine the type of completion wanted by checking which completion function will be called (e.g., filename_completer for filenames, location_completer for locations, etc.). This all works fine for myfirstcommand, because immediately after the command registration the Python backend already sets its completion function to filename_completer (which then causes the complete_line_internal function to choose the right set of word break chars). However, for mysecondcommand, this decision is postponed to when the completer function is evaluated, and the Python backend uses an internal completer (called cmdpy_completer). complete_line_internal doesn't know about this internal completer, and can't choose the right set of word break chars in time, which then leads to a bad decision when completing the "/hom" word. So, after a few attempts, I decided to create another callback in "struct cmd_list_element" that will be responsible for handling the case when there is an unknown completer function for complete_line_internal to work with. So far, only the Python backend uses this callback, and only when the user provides a completer method instead of registering the command directly with a completer class. I think this is the best option because it not very intrusive (all the other commands will still work normally), but especially because the whole completion code is so messy that it would be hard to fix this without having to redesign things. I have regtested this on Fedora 18 x86_64, without regressions. I also included a testcase. gdb/ChangeLog: 2014-09-03 Sergio Durigan Junior <sergiodj@redhat.com> PR python/16699 * cli/cli-decode.c (set_cmd_completer_handle_brkchars): New function.

Unify CLI/TUI interface to readline tab completion. This copies a lot of code from readline, but this is temporary. Readline currently doesn't export what we need.

Add max-completions parameter, and implement tab-completion limiting. This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be thrown whenever the completer has generated too many candidates to be useful. A new user-settable variable, "max_completions", is added to control this behaviour. A top-level completion limit is added to complete_line_internal, as the final check to ensure the user never sees too many completions. An additional limit is added to default_make_symbol_completion_list_break_on, to halt time-consuming symbol table expansions. gdb/ChangeLog: PR cli/9007 PR cli/11920 PR cli/15548 * cli/cli-cmds.c (complete_command): Notify user if max-completions reached. * common/common-exceptions.h (enum errors) <MAX_COMPLETIONS_REACHED_ERROR>: New value. * completer.h (get_max_completions_reached_message): New declaration.

gdb: Rework command completion on 'tui reg'. We previously specified a few known register groups for the 'tui reg' command. Other register groups could be accessed, but only by using the 'tui reg next' command and cycling through all the groups. This commit removes the hard coded sub-commands of 'tui reg' and instead adds dynamic completion of sub-commands based on the architecturally defined register groups, giving immediate access to all available register groups. There is still the 'next' and 'prev' commands for cycling through the register groups if that's wanted. The new code maintains the ability to only enter partial names for register groups, which is something we got for free when using the standard sub-command mechanism. The register (and register group) completer has been changed to use get_current_arch rather than using the architecture of the currently selected frame. When the target is running, this is equivalent, however, when the target is not running, using get_current_arch will provide results from the default architecture. gdb/ChangeLog: * completer.c: Add arch-utils.h include. (enum reg_completer_targets): New enum. (reg_or_group_completer_1): New function containing old reg_or_group_completer, add and use new parameter to control what is completed on.

PR python/16699: GDB Python command completion with overriden complete vs. completer class This PR came from a Red Hat bug that was filed recently. I checked and it still exists on HEAD, so here's a proposed fix. Although this is marked as a Python backend bug, this is really about the completion mechanism used by GDB. Since this code reminds me of my first attempt to make a good noodle, it took me quite some time to fix it in a non-intrusive way. The problem is triggered when one registers a completion method inside a class in a Python script, rather than registering the command using a completer class directly. For example, consider the following script: class MyFirstCommand(gdb.Command): def __init__(self): gdb.Command.__init__(self,'myfirstcommand',gdb.COMMAND_USER,gdb.COMPLETE_FILENAME) def invoke(self,argument,from_tty): raise gdb.GdbError('not implemented') class MySecondCommand(gdb.Command): def __init__(self): gdb.Command.__init__(self,'mysecondcommand',gdb.COMMAND_USER) def invoke(self,argument,from_tty): raise gdb.GdbError('not implemented') def complete(self,text,word): return gdb.COMPLETE_FILENAME MyFirstCommand () MySecondCommand () When one loads this into GDB and tries to complete filenames for both myfirstcommand and mysecondcommand, she gets: (gdb) myfirstcommand /hom<TAB> (gdb) myfirstcommand /home/ ^ ... (gdb) mysecondcommand /hom<TAB> (gdb) mysecondcommand /home ^ (The "^" marks the final position of the cursor after the TAB). So we see that myfirstcommand honors the COMPLETE_FILENAME class (as specified in the command creation), but mysecondcommand does not. After some investigation, I found that the problem lies with the set of word break characters that is used for each case. The set should be the same for both commands, but it is not. During the process of deciding which type of completion should be used, the code in gdb/completer.c:complete_line_internal analyses the command that requested the completion and tries to determine the type of completion wanted by checking which completion function will be called (e.g., filename_completer for filenames, location_completer for locations, etc.). This all works fine for myfirstcommand, because immediately after the command registration the Python backend already sets its completion function to filename_completer (which then causes the complete_line_internal function to choose the right set of word break chars). However, for mysecondcommand, this decision is postponed to when the completer function is evaluated, and the Python backend uses an internal completer (called cmdpy_completer). complete_line_internal doesn't know about this internal completer, and can't choose the right set of word break chars in time, which then leads to a bad decision when completing the "/hom" word. So, after a few attempts, I decided to create another callback in "struct cmd_list_element" that will be responsible for handling the case when there is an unknown completer function for complete_line_internal to work with. So far, only the Python backend uses this callback, and only when the user provides a completer method instead of registering the command directly with a completer class. I think this is the best option because it not very intrusive (all the other commands will still work normally), but especially because the whole completion code is so messy that it would be hard to fix this without having to redesign things. I have regtested this on Fedora 18 x86_64, without regressions. I also included a testcase. gdb/ChangeLog: 2014-09-03 Sergio Durigan Junior <sergiodj@redhat.com> PR python/16699 * cli/cli-decode.c (set_cmd_completer_handle_brkchars): New function.

Add max-completions parameter, and implement tab-completion limiting. This commit adds a new exception, MAX_COMPLETIONS_REACHED_ERROR, to be thrown whenever the completer has generated too many candidates to be useful. A new user-settable variable, "max_completions", is added to control this behaviour. A top-level completion limit is added to complete_line_internal, as the final check to ensure the user never sees too many completions. An additional limit is added to default_make_symbol_completion_list_break_on, to halt time-consuming symbol table expansions. gdb/ChangeLog: PR cli/9007 PR cli/11920 PR cli/15548 * cli/cli-cmds.c (complete_command): Notify user if max-completions reached. * common/common-exceptions.h (enum errors) <MAX_COMPLETIONS_REACHED_ERROR>: New value. * completer.h (get_max_completions_reached_message): New declaration.
