-(Started this file at 14 Feb 02, 18:18 GMT)
-
-I decided it would be clearest for everybody (including me!) if I make
-a record of patches that I apply. The starting point for all these is
-valgrind-20020214; patches applied to it before that snapshot was
-released are not recorded anywhere.
-
-
------------------------------- 14 Feb 02 ------------------------------
-
-Michael Matz <matz@kde.org>:
- this fixes the leak (32bytes/demangled symbol)in cplus-dem.c. It also
- again localizes the changes to libiberty's cp-demangle.c at the top with
- some #defines. (It also has some unrelated changes like header guarding
- and making symbol sets disjoint, these are minor and were needed for the
- demangle_test program, and are local to the demangler)
-
- JRS: applied it, but it still seems to leak, running a g++2.96 compiled
- program, at least (/usr/bin/kedit as installed with RH72).
- (reenable VG_(show_all_arena_stats)() at vg_demangle.c:63 to see this)
-
-
-Michael Matz <matz@kde.org>
- here the patch for changing order of restorage of %esp to not trash
- simulees stack
-
-
-Simon Hausmann <hausmann@kde.org>
- I attached a patch for the latest vg snapshot to implement better
- support for shmat. Vg now correct marks the region returned by shmat
- as read or read-writable (we have to do that blindly as there is no
- way to figure out if another process initialized the data or not) .
- Also the patch adds a paranoia check for the buffer passed with
- shmctl. What's left todo is to make shmdt correctly mark the shm
- segment as invalid again, but I see no easy way to figure out the
- shm segment size just from the base address. Anyone? :)
- Otherwise it'll probably require keeping a copy of the allocated
- mappings inside vg -- shouldn't be expensive though.
- [...]
- Oops, my previous shm patch contained a little bug in that it called
- must_be_readable/writable for shmctl even when the address was 0
- (which for example is the case when using IPC_RMID to remove a
- shared memory segment, which is perfectly valid) . Attached the
- updated patch that makes valgrinding Qt/Embedded apps possible :)
-
-
-me:
- Check for accessibility changes for first and last 64k of address
- space after every system call, so as to catch syscall wrapper
- bugs as soon as they happen
-
-
-Simon Hausmann <hausmann@kde.org>
- The socketpair handler checks that the two fds passed must be
- readable, but I think the check should use must_be_writable instead
- as the kernel does not read those values but fills them in.
-
-
-Simon Hausmann <hausmann@kde.org>
- Here's a patch that implements checking of arguments for
- sendmsg/recvmsg, as part of the socket syscall.
- [...]
- Oops, I just realized that the recvmsg wrapper should mark the
- fields of the received message as readable, as the kernel hopefully
- initialized them :)
- [...]
- Corrected patch attached.
-
-
-Nick Nethercote <njn25@cam.ac.uk>
- [Implemented pushaw/pushal/popaw/popal]
-
- They're kind of ugly due to the special treatment of %esp, but there
- didn't seem to be any elegant way around it. You may object to my
- heinous magic number use with the registers.
-
- It seems to work ok, but I'd check it carefully if I were you. In
- particular, I've only tried it with POPAD. (I think; gcc only accepts
- 'popa' in assembler files, and according to the Intel docs will probably
- choose between POPA and POPAD by looking at the D flag of the current
- code segment's descriptor. I'm guessing this is 32-bits for my little
- test program.)
-
-
-Dirk Mueller <mueller@kde.org>
- below a patch for checking if allocations are done correctly in C++
- applications. it checks if new is free'ed by delete, new [] by delete [],
- and malloc, calloc, realloc by free().
-
- It works for me <tm>, not intensively tested yet.

-
- I.e. I would find the attached patch more usefull, which introduces an
- --bt-size=<num> option (with docu ;-) ) but removes that long=yes/no
- option.
-
- JRS: the final name for the option is --num-callers
-
-
------------------------------- 15 Feb 02 ------------------------------
-
-me:
- fix assertion failure in VG_(malloc_aligned) (duh. duh. duh.)
-
-
-Michael Matz <matzmich@cs.tu-berlin.de>
- [finally fix the last space leak in the demangler]
- this should now fix the rest of the leaks. The old c++ demangler is
- really crappy code, therefor it took longer to find the leaks. ;)
-
-
-Simon Hausmann <hausmann@kde.org>
- Here are two micro patches for vg :)
-
- The first one fixes what I think is a bug: I think the result param
- of llseek before the actual syscall should be checked for
- writability instead of readability.
-
- The second one is a quick workaround for an assertion in the
- demangler that I hit quite sometimes (I'm surprised noone else has
- hit it before, maybe it's gcc3 specific though :) . I'm too lazy to
- write a full strtol replacement for now ;) , so just returning an
- error will keep the program running and output the mangled symbol
- instead.
-
-
------------------------------- 17 Feb 02 ------------------------------
-
-me:
- Implement cleverer semantics for 4-byte integer loads from partially
- valid addresses, following complains from Coolo re spurious warnings
- from gcc-inlined strlen()s. As part of this, hardwire the default
- behaviour of --bad-addr-value and get rid of this flag entirely.
- New flag --partial-loads-ok=no|yes [default yes] controls use of
- new semantics. Also as a result, stop recommending people use
- --sloppy-malloc=yes by default.
-
-me:
- Options are now read from env var VALGRIND_OPTS.
- Also remove need to edit hardware install dir in shell script.
-
-
-Michael Matz <matzmich@cs.tu-berlin.de>
-Simon Hausmann <hausmann@kde.org>
- this fixes some leaks in the v3 demangler found by Simon (Julian: i.e.
- those we couldn't possibly run into, as we use v2 demangling).
-
-
------------------------------- 18 Feb 02 ------------------------------
-
-me:
- Tighten up the conditions for which --partial-loads-ok=yes is allowed
-
-me:
- Error management: slow down collecting errors after the 50th
- and stop altogether after the 500th
-
-me:
- Implement --workaround-gcc296-bugs, so RH 7.X and Mandrake users
- can use their default compilers.
-
-
------------------------------- 20 Feb 02 ------------------------------
-
-me:
- Massive overhaul of the signal machinery so that signals can be
- delivered to the client even when it is blocked in a system call.
- This fixes the kmail-deadlocks-on-valgrind problem.
-
------------------------------- 21 Feb 02 ------------------------------
-
-me:
- Implement GDB attachment to the program.
-
-Stephan Kulow <coolo@kde.org>
- Implement a few more syscall wrappers
-
------------------------------- 24 Feb 02 ------------------------------
-
-me:
- Cleanup of the signal machinery. Now we deal with signals purely
- at the kernel interface, rather than muddying glibc's and the kernel's
- conflicting concepts of some of the calls and structures.
-
-Kevin Dwyer <kevin@pheared.net>
- Implement bazillions of syscall wrappers for ioctls
-
-me:
- minor cleanups in vg_memory.c
-
------------------------------- 4 Mar 02 -------------------------------
-
-This file is falling significantly behind reality.
-
-Me: get rid of this pointless and incorrect assert:
- vg_memory.c:441 (set_address_range_perms): Assertion `len < 30000000' failed.
-
-Me: remove incorrect assert:
- vg_assert(u_in->flags_w != FlagsEmpty);

------------------------------- 6 Mar 02 -------------------------------
-
-Martin Nicolay <martin@osm-gmbh.de>
- Implement fstatfs (100)
- Implement ioctl FIOASYNC
- Implement ioctl SIOCSPGRP (was previously noted-but-unhandled)
-
-Sanjay Ghemawat <sanjay@google.com>
- Implement sync (36)
- Make mallopt() into a no-op, rather than panic
-
------------------------------- 7 Mar 02 -------------------------------
-
-Me
- Write a great deal of technical docs about Valgrind internals
- See docs/techdocs.html
-
-Me
- Complete renaming of the kernel interface (vg_kerneliface.h)
- definitions.
-

-Martin Jones <mjones@trolltech.com>
- Implement ioctl MIXER_WRITE(0)
-
-Jon Trowbridge <trow@ximian.com>
- Implement syscall pwrite (181)
-
-Me
- Revamp the leak detector; fix various segfaults and bus errors in
- it, and add the --show-reachable=no|yes flag, which makes it more
- useful.
-
------------------------------- 8 Mar 02 -------------------------------
-
-Me
- Split up huge basic blocks into pieces, to avoid this:
- vg_main.c:495 (vgPlain_create_translation_for): Assertion
- `trans_size > 0 && trans_size < 65536' failed
-
-Crispin Flowerday <cflowerday@zeus.com>
- Implement syscall sendfile (187)
- Allow accept to have NULL 3rd argument

-
-Me
- Fix obscure simulated CPU bug causing this:
- -1: CMOVW t34, t36 (-rOSZACP)
- valgrind: vg_to_ucode.c:4197 (disInstr): Assertion `sane' failed.
- (Spotted by Thorsten Schnebeck <thorsten.schnebeck@gmx.net>)
-
-Me
- Add yet more suppressions to linux24.supp
-
-Me [subrev b only]
- In the leak checker, use __builtin_{setjmp,longjmp} instead of the
- glibc (pthread) versions. This avoids a subtle memory corruption
- problem caused by pthread_longjmp (or whatever it is called), which
- finally manifests itself in this assertion failure:
- vgPlain_primary_map[i] == & vg_distinguished_secondary_map
- Many thanks to Michael Matz for coming up with an easy solution
- which saved me hours of pissing around.
