2020-04-10[gdb/cli] Don't let python colorize strip leading newlinesTom de Vries1-1/+1
Consider the test-case gdb.base/async.exp. Using the executable, I run to main, and land on a line advertised as line 26: ... $ gdb outputs/gdb.base/async/async -ex start Reading symbols from outputs/gdb.base/async/async... Temporary breakpoint 1 at 0x4004e4: file gdb.base/async.c, line 26. Starting program: outputs/gdb.base/async/async Temporary breakpoint 1, main () at gdb.base/async.c:26 26 y = foo (); ... But actually, the line turns out to be line 28: ... $ cat -n gdb.base/async.c ... 26 y = 2; 27 z = 9; 28 y = foo (); ... This is caused by the following: the python colorizer initializes the lexer with default options (no second argument to get_lexer_for_filename): ... def colorize(filename, contents): # Don't want any errors. try: lexer = lexers.get_lexer_for_filename(filename) formatter = formatters.TerminalFormatter() return highlight(contents, lexer, formatter) ... which include option stripnl=True, which strips leading and trailing newlines. This causes the python colorizer to strip the two leading newlines of async.c. Fix this by initializing the lexer with stripnl=False. Build and reg-tested on x86_64-linux. gdb/ChangeLog: 2020-04-10 Tom de Vries <tdevries@suse.de> PR cli/25808 * python/lib/gdb/__init__.py: Initialize lexer with stripnl=False. gdb/testsuite/ChangeLog: 2020-04-10 Tom de Vries <tdevries@suse.de> PR cli/25808 * gdb.base/style.c: Add leading newlines. * gdb.base/style.exp: Use gdb_get_line_number to get specific lines.

2020-01-21Allow use of Pygments to colorize source codeTom Tromey1-0/+14
While GNU Source Highlight is good, it's also difficult to build and distribute. For one thing, it needs Boost. For another, it has an unusual configuration and installation setup. Pygments, a Python library, doesn't suffer from these issues, and so I thought it would be a reasonable fallback. This patch implements this idea. GNU Source Highlight is preferred, but if it is unavailable (or fails), the extension languages are tried. This patch also implements support for Pygments. Something similar could be done for Guile, using: https://dthompson.us/projects/guile-syntax-highlight.html However, I don't know enough about Guile internals to make this happen, so I have not done it here. gdb/ChangeLog 2020-01-21 Tom Tromey <tromey@adacore.com> * source-cache.c (source_cache::ensure): Call ext_lang_colorize. * python/python.c (python_extension_ops): Update.

I'm seeing this failure: ... (gdb) print /x $bnd0 = {0x10, 0x20}^M $23 = {lbound = 0x10, ubound = 0x20}^M (gdb) FAIL: gdb.arch/i386-mpx.exp: verify size for bnd0 ...

2019-08-22Make GDB compile with Python 3 on MinGWChristian Biesinger1-0/+26
PyFile_FromString and PyFile_AsFile have been removed in Python 3. There is no obvious replacement that works here, and we can't just pass our FILE* to a DLL in Windows because it may use a different C runtime. So we just call a Python function which reads and executes file contents. Care must be taken to execute it in the context of __main__. Tested by inverting the ifdef and running the testsuite on Debian Linux (even without the patch, I failed at running the testsuite on Windows). I did test with both Python 2 and 3. gdb/ChangeLog: 2019-08-22 Christian Biesinger <cbiesinger@google.com> * python/lib/gdb/__init__.py (_execute_file): New function. * python/python.c (python_run_simple_file): Call gdb._execute_file on Windows.

2019-08-07Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers1-4/+4
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.

2016-07-12PR python/19293 - invalidate frame cache when unwinders changeTom Tromey2-0/+3
PR python/19293 notes that when a Python unwinder is disabled, the frame cache is not invalidated. This means that disabling an unwinder doesn't have any immediate effect -- but in my experience it's often the case that I want to enable or disable an unwinder in order to see what happens. This patch adds a new gdb.invalidate_cached_frames function and arranges for the relevant bits of library code to call it. I've only partially documented this function, considering a warning sufficient without going into all the reasons ordinary code should not call it. The name of the new function was taken from a comment in frame.h next to reinit_frame_cache. No new test as I think the updates to the existing test are sufficient to show that the code is working as intended.

2016-01-20Fix sorting of enum values in FlagEnumerationPrinterSimon Marchi1-1/+1
The lambda function used to sort the enumerator list does not work properly. This list consists of tuples, (enum label, enum value). The key function returns x.enumval. enumval not being defined for a tuple, we see this exception in the test log: Python Exception <class 'AttributeError'> 'tuple' object has no attribute 'enumval' The function should return the second item of the tuple, which is the enumval. The pretty-printer still worked mostly correctly, except that the enumeration values were not sorted. The test still passed because the enumeration values are already sorted where they are defined. The test also passed despite the exception being printed, because the right output was printed after the exception: print (enum flag_enum) (FLAG_1) Python Exception <type 'exceptions.AttributeError'> 'tuple' objecthas no attribute 'enumval':M $7 = 0x1 [FLAG_1] (gdb) PASS: gdb.python/py-pp-maint.exp: print FLAG_1 New in v2: - Improved test case, I stole Pedro's example directly. It verifies that the sorting of enumerators by value works, by checking that printing FOO_MASK appears as FOO_1 | FOO_2 | FOO_3. I noticed that I could change the regexps to almost anything and the tests would still pass. I think it was because of the | in there. I made them more robust by using string_to_regexp. I used curly braces { } instead of quoting marks " " for strings, so that I could use square brackets [ ] in them without having to escape them all. I also removed the "message" part of the tests, since they are redundant with the command, and it's just more maintenance to have to update them.

To solve it, I simply added wrapped v in a call to int(). '%x' % int(v) In Python 2, the int type is implemented with a "long" in C, so on x86-32 it's 32-bits. I was worried that doing int(v) would truncate the value and give wrong results for enum values > 32-bits. However, the int type != the int function. The int function does the right thing, selecting the right integer type for the given value. I tested with large enum values on x86-32 and Python 2, and everything works as expected. gdb/ChangeLog: * python/lib/gdb/printing.py (_EnumInstance.to_string): Explicitly convert gdb.Value to integer type using int().

2014-12-15python extended prompt: Use os.getcwd() instead of os.getcwdu()Simon Marchi1-1/+1
It seems like using os.getcwdu() here is wrong both for Python 2 and Python 3. For Python 2, this returns a 'unicode' object, which tries to get concatenated to a 'str' object in substitute_prompt. The implicit conversion works when the unicode string contains no accent. When it does contain an accent though, displaying the prompt results in the following error: (gdb) set extended-prompt \w ... File "/home/simark/build/binutils-gdb-python2/gdb/data-directory/python/gdb/prompt.py", line 138, in substitute_prompt result += str(cmd(arg)) UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 49: ordinal not in range(128) When using os.getcwd() instead, it works correctly. I suppose that Python does the necessary decoding internally. For Python 3, this method simply does not exist. It works fine with os.getcwd(). gdb/ChangeLog: * python/lib/gdb/prompt.py (_prompt_pwd): Use os.getcwd() instead of os.getcwdu().
2014-10-30Don't replace '\' with '\\' in before_prompt_hookYao Qi1-2/+1
In gdb/command/prompt.py:before_prompt_hook, the '\' in the new prompt is replaced with '\\', shown as below, > def before_prompt_hook(self, current): > if self.value is not '': > newprompt = gdb.prompt.substitute_prompt(self.value) > return newprompt.replace('\\', '\\\\') > else: > return None I don't see any explanations on this in comments nor email. As doc said, "set extended-prompt \w" substitute the current working directory, but it prints something different from what pwd or os.getcwdu() prints on mingw32 host. (gdb) python print os.getcwdu()^M \\build2-lucid-cs\yqi\yqi\arm-none-eabi (gdb) pwd^M Working directory \\build2-lucid-cs\yqi\yqi\arm-none-eabi (gdb) set extended-prompt \w \\\\build2-lucid-cs\\yqi\\yqi\\arm-none-eabi This makes me think whether the substitution in before_prompt_hook is necessary or not. This patch is to remove this substitution. Run gdb.python on x86_64-linux and arm-none-eabi on mingw32 host. No regressions. gdb: 2014-10-30 Yao Qi <yao@codesourcery.com> * python/lib/gdb/command/prompt.py (before_prompt_hook): Don't replace '\\' with '\\\\'.

2014-01-23avoid python exception in FrameDecorator.pyTom Tromey1-2/+10
This fixes a bug in FrameDecorator.py. FrameVars seems to assume that Frame.block can return None if there is no block. However, it actually throws an exception. I saw this bug while developing a frame filter, but unfortunately I don't know how to reproduce it. It seems to me that the SAL tests in _is_limited_frame should exclude the bad cases; and in my attempts to write a test they do. Nevertheless I think the fix is reasonably obvious and ought to go in. 2014-01-23 Tom Tromey <tromey@redhat.com> PR python/16485: * python/lib/gdb/FrameDecorator.py: (FrameVars.fetch_frame_args): Handle exception from frame.block.
