Johannes Gijsbers 25b38c8969 Improvements when running pdb as a script.
Bug fixes:

* Use fresh copy of globals/locals so the script being debugged can't access
  the pdb namespace (e.g.: p line_prefix will no longer work).

* Remove pdb.py's path from sys.path. Having it in there is normally not a
  problem, but it could prove irritating when messing with PYTHONPATH or
  invoking pdb via /usr/bin/pdf.

* You can now set a breakpoint on the script being debugged, even if the script
  doesn't end with a '.py' extension. Also, setting breakpoints with absolute
  paths now works reliably.

Enhancements:

* Go directly to the first line of the script.

* Enter post-mortem debugging if the script being debugged doesn't catch an
  exception.

* Restart the script being debugged and preserve debugger state when the script
  being debugged exits.

Cleanup:

* Moved the __main__ method into a main() function.

* Kill the (undocumented, not in __all__) mainmodule/mainpyfile globals, add a
  mainpyfile attribute to pdb.

Thanks Ilya Sandler for the patch!

Johannes Gijsbers 4a9faa1ea0 Patch #1003640: replace checkline() function parsing with new breakpoint logic:
1) When a breakpoint is set via a function name:
- the breakpoint gets the lineno of the def statement
- a new funcname attribute is attached to the breakpoint

2) bdb.effective() calls new function checkfuncname() to handle:
- def statement is executed: don't break.
- a first executable line of a function with a breakpoint on the lineno of the
def statement is reached: break.

This fixes bugs 976878, 926369 and 875404. Thanks Ilya Sandler.

Johannes Gijsbers 34c4120731 bug #989672: pdb.doc and the help messages for the help_d and help_u methods
of the pdb.Pdb class gives have been corrected. d(own) goes to a newer frame,
u(p) to an older frame, not the other way around.

Andrew M. Kuchling b1f8bab654 [Bug #741171] pdb crashes when enabling a non-existing breakpoint
Check the supplied breakpoint number more carefully.
(Incompatibility: before this patch, "enable -1" would enable
the last breakpoint on the list; now -1 is not a legal ID.  Not sure
anyone would ever use negative indices...)

2.2 bugfix candidate, assuming making -1 illegal isn't considered a problem.

Guido van Rossum a12fe4e81f - New function sys.call_tracing() allows pdb to debug code
recursively.
- pdb has a new command, "debug", which lets you step through
  arbitrary code from the debugger's (pdb) prompt.

[ 643835 ] Set Next Statement for Python debuggers

with a few tweaks by me: adding an unsigned or two, mentioning that
not all jumps are allowed in the doc for pdb, adding a NEWS item and
a note to whatsnew, and AuCTeX doing something cosmetic to libpdb.tex.

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Guido van Rossum e85c93f521 Sjoerd Mullender:
When you set a breakpoint on a function with a multi-line argument
list, the breakpoint is actually set on the second line of the
arguments instead of the first line of the body.  This patch fixes
that.

Guido van Rossum 4b8c6eaf8b Actually, the previous batch's comment should have been different;
*this* set of patches is Ka-Ping's final sweep:

The attached patches update the standard library so that all modules
have docstrings beginning with one-line summaries.

A new docstring was added to formatter.  The docstring for os.py
was updated to mention nt, os2, ce in addition to posix, dos, mac.

Guido van Rossum 54f22ed30b More trivial comment -> docstring transformations by Ka-Ping Yee,
who writes:

Here is batch 2, as a big collection of CVS context diffs.
Along with moving comments into docstrings, i've added a
couple of missing docstrings and attempted to make sure more
module docstrings begin with a one-line summary.

I did not add docstrings to the methods in profile.py for
fear of upsetting any careful optimizations there, though
i did move class documentation into class docstrings.

The convention i'm using is to leave credits/version/copyright
type of stuff in # comments, and move the rest of the descriptive
stuff about module usage into module docstrings.  Hope this is
okay.

Guido van Rossum 19878f58fe Sjoerd Mullender writes:
I regularly find that pdb sets the breakpoint on the wrong line when I
try to set a breakpoint on a function.  This fixes the problem
somewhat.
The real problem is that pdb tries to parse the Python source code to
find the first executable line.  A better way might be to inspect the
code object, or even have a variable in the code object
co_firstexecutablelineno, but that's too much work.

The patch fixes the problem when the first code line after the def
statement contains the start *and* end of a triple-quoted string.  The
code assumed that the end of a triple-quoted string is not on the same
line as the start, and so it would skip to the end of the *next*
triple-quoted string.

Barry Warsaw 2bee8feac6 Pdb.lineinfo(): Don't use os.popen('egrep ...') to find the line in
the file that a function is defined on.  Non-portable to Windows and
JPython.  Instead, new find_function() uses re module on a similar
(simple-minded) pattern.

Guido van Rossum 3a98e78a6e Richard Wolff's additional changes; some layout nits, and change the
alias delimiter to ';;'.
1998-09-17 15:00:30 +00:00
Guido van Rossum 2424f855f3 Richard Wolff's changes:
pdb.py  Uses the Breakpoint class so one can enable/disable breakpoints,
	set temporary ones, set ignore counts, and conditions.  The last
	can be set using the 'b' command
		b 243 , i>4		( b 243,i>4 if you are space adverse)
	or with the condition command so conditions can be changed
	for a particular breakpoint.

	Breakpoints are numbered from 1 on, and if a breakpoint is deleted,
	the number is not reused.  All the breakpoint handling commands
	refer to breakpoints by number.  To be consistent, the clear command
	does so as well, which is the one change from the original pdb that
	is not transparent.  Thus only the breakpoint command 'b' uses a
	line number or file:line or method.  You can also give
		b whrandom.random    and the method will be searched for along
	sys.path.  This is implemented with an 'egrep' command and so
	is not as portable as it might be.  [ see  lineinfo() and
	lineinfoCmd ]

	Breakpoints cannot be set at a line that is blank or a '#' comment
	or starts a triply quoted comment.  This is because I would like
	this behavior in my DDD interface and think it reasonable for
	pdb as well.  It can be removed readily, however as it is all
	incorporated in the routine checkline().  If one attempts to
	set a breakpoint at a 'def' line, the breakpoint is automatically
	moved to the first executable line after the 'def'.  This too is
	in checkline().

	do_EOF() returns zero so typing an end-of-file character as a command
	does nothing.  'quit' does the quitting.

	The routine defaultFile() is present so as to preserve the current
	pdb behavior and yet allow me to override it in pydb.

	There's some code in lineinfo() that is probably mainly useful only
	for pydb and if you prefer, much up to the comment "Best first guess"
	could be removed.

	Keith Davidson provided the code for handling $HOME/.pdbrc and
	./.pdbrc, and it has been incorporated.  He also provided the
	alias handling routine.  I modified it a bit so it could live
	nicely in precmd().  He and I have been in contact; he has the
	new pdb (and pydb) with his code incorporated.  He also asked
	about the possibility of allowing multiple commands on one
	line, such as step;step  or s;s  or with an alias such as
		alias ct tbreak %1 ; continue
	and since it was so easy, that's in place as well.  It's a simple
	'split the line at the first ";"' operation and puts the second
	half in the command queue (self.cmdqueue).  This has the unfortunate
	effect of destroying a line like   print "i: "+i+"; j: "+j
	but either there's a simple way to deal with this, or my attitude
	will remain that pdb is a debugger, not a compiler/parser/etc.
	An alias like   alias 4s  s;;s;
	will work because the adjacent and trailing ";" act like a <cr> which
	repeats the last command.  Of course, either s;s;s;s or s;;;  would be
	a bit more sensible.

	The help commands have been updated.

Guido van Rossum 1f00eed8b5 Feature added by Harri Pasanen (at my suggestion): .py suffix on
filename may be omitted.
1998-07-22 13:35:21 +00:00
Guido van Rossum b5699c7240 Added support for specifying a filename for a breakpoint, roughly
according to an idea by Harri Pasanen (but with different syntax).
This affects the 'break' and 'clear' commands and their help
functions.  Also added a helper method lookupmodule().

Also:

- Try to import readline (important when pdb is used from/as a script).
- Get rid of reference to ancient __privileged__ magic variable.
- Moved all import out of functions to the top.
- When used as a script, check that the script file exists.
1998-07-20 23:13:54 +00:00
Guido van Rossum 46c86bbca9 A working version of the 'args' command (it prints the current values
of the variables known to hold arguments, but that's as close as I can
get, and generally it's close enough).
