New Revision: 10651
Log:
Improve checking for pthread_mutex_cond operations: implement a check
for consistent binding between the CV and the mutex, as specified by
POSIX. Add commented out code for some other checks that could be
done but aren't, as they'd give false positives.

I'd be fairly happy even with such a restriction -- the restrictions of ltrace that I'm not happy with are: * That it only traces calls performed through the PLT, not through a dynamic mechanism like dlopen()/dlsym() or through callbacks, no matter what t you put in your config files. This seems to be a fundamental limitation of ltrace, since there is no way to tell whether a given symbol represents code or data just from the symbol. * That it currently only traces calls from the main executable. This is not a fundamental limitation, but it would still probably be a pain to lift. > For other symbols, nothing is guaranteed.

Well, that could certainly be added at some point, but it's not something I desire particularly strongly at this point, and I'm guessing that valgrind doesn't currently parse type information? The most interesting calls to trace are those to public APIs (or from public APIs to callbacks), anyway ;-). |

No. ltrace has one big advantage: it only logs exported symbols, which have to adhere to the ABI, ie. to a fixed convention on the given platform. For other symbols, nothing is guaranteed. Especially, argument passing for the same function could change with different compilation options. Thus, a config file can not work. You have to use debug information here. Josef |

It shouldn't be hard to at least do as well as ltrace does here; what
it does is all based on config files like this:
; ltrace.conf
;
; ~/.ltrace.conf will also be read, if it exists. The -F option may be
; used to suppress the automatic inclusion of both this file and
; ~/.ltrace.conf, and load a different config file or config files
; instead.
; Argument types:
; + == May vary (ie, is a returned value) (prefix)
; void
; int
; uint == (unsigned int)
; long
; ulong == (unsigned long)
; octal == (unsigned) [written in octal]
; char
; short == (short)
; ushort == (unsigned short)
; addr == (void *) [unsigned, written in hexa]
; file == (FILE *) [TODO]
; format == ((const char *), ...) [printf() like] [TODO]
; string == (char *)
; string[argN] == (char *) [N>0] [show only up to (arg N) bytes]
; string[eltN] == (char *) [N>0] [show only up to (elt N) bytes]
; string[retval] == (char *) [show only up to (return val) bytes]
; string[arg0] == (char *) [same as string[retval]]
; string[N] == (char *) [N>0] [show only up to N bytes]
; type* == (type *) [pointer to any other type]
; enum (key=value,key=value,...) [enumeration, see below]
; array(type,argN)
; == (type[SIZE]) [array of (arg N) elements]
; array(type,eltN)
; == (type[SIZE]) [array of (struct element N) elements]
; array(type,N) == (type[N]) [array of N elements]
; struct(type,type,...)
; == (struct {...}) [struct of several types]
;
; Backwards-compatibility:
; string0 == (char *) [same as string[retval]]
; stringN == (char *) [N>0] [same as string[argN]]
; Typedefs
;
; To make it easier to specify argument lists, you can use 'typedef'
; directives to avoid repeating complex parameter descriptors:
;
; typedef color = enum(RED=1,BLUE=2,GREEN=3)
; void draw_line(color,int,int,int,int)
; void draw_square(color,int,int,int,int)
;
; Enumerations
;
; The syntax is a parenthesized list of key=value assignments, like so:
; enum (F_DUPFD=0,F_GETFD=1,F_SETFD=2)
; an example usage might look like
; int fcntl(int,enum (F_DUPFD=0,F_GETFD=1,F_SETFD=2))
;
; Arrays
;
; NOTE: Uses of array(...) alone are very rare. You almost always
; want array(...)*. The exceptions are when you have a fixed-size
; array.
;
; Structs
;
; NOTE: Uses of struct(...) alone are very rare. You almost always
; want struct(...)* (a pointer to a struct) anyway. Most compilers
; pass structs as pointers anyway, and those that don't are not yet
; supported. The one time when you want to use a non-pointer
; struct(...) type are when you have an array of structs, or a struct
; containing another struct.
;
; For example, if you have
; struct s1 {
; int y_size;
; int * y;
; int z[3];
; struct { char c; } a;
; struct { char c; } * b;
; }
; and a function
; void f(struct s1*)
; then the corresponding ltrace spec is
; void f(struct(int,array(int,elt0),array(int,3),struct(char),struct(char)*)*)
; which, formatted similarly to the C declaration, looks like
; void f(struct(
; int,

; struct(char)*

It would be even better to not have the process ID on every line. That way you can use the mouse to select the command line and then paste it into the shell again. I use that frequently and find it handy. The PID would get in the way there. I definitely like the shortened preamble. Florian |

Hi, Bug 197933 (https://bugs.kde.org/show_bug.cgi?id=197933) suggests putting the command line in the preamble of all Valgrind runs (excluding those invoked with -q). This makes --trace-children=yes much easier to use, because you can work out which process relates to which command invocation. It's also useful if you save Valgrind output to a file, as it's clear exactly what you ran. I have a patch that does this (it's attached). It wraps the command before 80 chars where possible, as the following example shows (best viewed with a fixed-width font): ==9717== Memcheck, a memory error detector. ==9717== Copyright (C) 2002-2009, and GNU GPL'd, by Julian Seward et al. ==9717== Using Valgrind-3.5.0.SVN and LibVEX; rerun with -h for copyright info ==9717== Command: date 11 23 4a \ ==9717== aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaa \ ==9717== aaa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 \ ==9717== 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 \ ==9717== fffffffffffffffffffffffffffff 1 2 3 \ ==9717== bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb I used "Command:" instead of "Running:" (as suggested in the bug report) because it seemed better. I thought about putting "Command:" in front of every line, to make it easier to parse the text, but then I figure if you want to do that you should really be using the XML output. I'll also have to change a lot of the regtest expected outputs (the attached patch doesn't have that yet) but that's not a big deal. Anyone have any other thoughts about this? Nick |
