What did I forget? git-svn-id: svn://svn.valgrind.org/valgrind/branches/VALGRIND_3_9_BRANCH@13682 --- NEWS | 848 ++++++++++++++++++----------------------------------------- 1 file changed, 261 insertions(+), 587 deletions(-) diff --git a/NEWS b/NEWS index 9a2ec4b1b3..b9b825e4c6 100644 --- a/NEWS +++ b/NEWS @@ -1,103 +1,161 @@ -Release 3.9.0 (?? ?????? 201?) -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Release 3.9.0 (XX October 2013) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +3.8.0 is a feature release with many improvements and the usual +collection of bug fixes. + +This release supports X86/Linux, AMD64/Linux, ARM/Linux, PPC32/Linux, +PPC64/Linux, S390X/Linux, MIPS32/Linux, MIPS64/Linux, ARM/Android, +X86/Android, X86/MacOSX 10.7 and AMD64/MacOSX 10.7. Support for +MacOSX 10.8 is significantly improved relative to the 3.8.0 release. * ================== PLATFORM CHANGES ================= -* Support for MIPS64 LE and BE running Linux. Valgrind has been tested - on MIPS64 Debian Squeeze and Debian Wheezy distributions. +* Support for MIPS64 LE and BE running Linux. Valgrind has been + tested on MIPS64 Debian Squeeze and Debian Wheezy distributions. * Support for MIPS DSP ASE on MIPS32 platforms. - Support for s390x Decimal Floating Point instructions on hosts that +* Support for s390x Decimal Floating Point instructions on hosts that have the DFP facility installed. - Power8 (Power ISA 2.07 support) +* Support for POWER8 (Power ISA 2.07) instructions + +* Support for Intel AVX2 instructions. This is available only on 64 + bit code. - Intel AVX2 support - Intel HTM support (kind of) - Power HTM support (kind of) +* Initial support for Intel Transactional Synchronization Extensions, + both RTM and HLE. +* Initial support for Hardware Transactional Memory on POWER. + +* Improved support for MacOSX 10.8 (64-bit only). Memcheck can now + run large GUI apps tolerably well. * ==================== TOOL CHANGES ==================== + * Memcheck: - - Using the options --show-leak-kinds=kind1,kind2,.. and - --errors-for-leak-kinds=kind1,kind2,.., each leak kind (definite, indirect, - possible, reachable) can now be individually reported and/or counted as - an error. - In a leak suppression entry, an optional line 'match-leak-kinds:' - controls which leak kinds are suppressed by this entry. - This is a.o. useful to avoid definite leaks being "catched" - by a suppression entry aimed at suppressing possibly lost blocks. - - - The option --leak-check-heuristics=heur1,heur2,... can activate - various heuristics to decrease the number of false positive - "possible leaks" for C++ code. The available heuristics are - detecting valid interior pointers to std::stdstring, to new[] allocated - arrays with elements having destructors and to interior pointers pointing - to an inner part of a C++ object using multiple inheritance. - - - The option --keep-stacktraces controls which stack trace(s) to keep for - malloc'd and/or free'd blocks. This can be used to obtain more information - for 'use after free' errors or to decrease Valgrind memory and/or cpu usage - by recording less information for heap blocks. - - - The list of used suppressions (shown when giving the -v option) - now shows for the leak suppressions how many blocks and bytes were - suppressed during the last leak search for each suppression. - The suppression count for a leak suppression shows the total nr - of loss records which were suppressed by this suppression. + - Improvements in handling of vectorised code, leading to + significantly fewer false error reports. You need to use the flag + --partial-loads-ok=yes to get the benefits of these changes. + + - Better control over the leak checker. It is now possible to + specify which leak kinds (definite/indirect/possible/reachable) + should be displayed, which should be regarded as errors, and which + should be suppressed by a given leak suppression. This is done + using the options --show-leak-kinds=kind1,kind2,.., + --errors-for-leak-kinds=kind1,kind2,.. and an optional + "match-leak-kinds:" line in suppression entries, respectively. + + - Reduced "possible leak" reports from the leak checker by the use + of better heuristics. The available heuristics provide detection + of valid interior pointers to std::stdstring, to new[] allocated + arrays with elements having destructors and to interior pointers + pointing to an inner part of a C++ object using multiple + inheritance. They can be selected individually using the option + The option --leak-check-heuristics=heur1,heur2,... + + - Better control of stacktrace acquisition for heap-allocated + blocks. Using the --keep-stacktraces option, it is possible to + control independently whether a stack trace is acquired for each + allocation and deallocation. This can be used to create better + "use after free" errors or to decrease Valgrind's resource + consumption by recording less information. + + - Better reporting of leak suppression usage. The list of used + suppressions (shown when the -v option is given) now shows, for + each leak suppressions, how many blocks and bytes it suppressed + during the last leak search. + + - Line numbers for used suppressions. The list of used suppressions + (shown when the -v option is given) now shows, for each used + suppression, the file name and line number where the suppression + is defined. + +* Helgrind: + + - False errors resulting from the use of statically initialised + mutexes and condition variables (PTHREAD_MUTEX_INITIALISER, etc) + have been removed. + + - False errors resulting from the use of pthread_cond_waits that + timeout, have been removed. * ==================== OTHER CHANGES ==================== - - The default nr of sectors in the translation cache has been - decreased to 6 on android platforms, and increased to 16 - on all other platforms. A sector (lazily allocated) uses several - MB depending on the tool (about 40MB for memcheck). - The option --num-transtab-sectors allows to specify how - many sectors Valgrind can allocate. +* Some attempt to tune Valgrind's space requirements to the expected + capabilities of the target: - - Option --merge-recursive-frames= tells Valgrind to - detect and merge (collapse) recursive calls when recording stack traces. - When your program has recursive algorithms, this limits - the memory used by Valgrind for recorded stack traces and avoid - recording uninteresting repeated calls. - The value is changeable using the monitor command - 'v.set merge-recursive-frames'. + - The default size of the translation cache has been reduced from 8 + sectors to 6 on Android platforms, since each sector occupies + about 40MB when using Memcheck. - - valgrind.h has a new request VALGRIND_MONITOR_COMMAND. - This can be used to execute gdbserver monitor commands from - the client program. + - The default size of the translation cache has been increased to 16 + sectors on all other platforms, reflecting the fact that large + applications require instrumentation and storage of huge amounts + of code. For similar reasons, the number of memory mapped + segments that can be tracked has been increased by a factor of 6. - - Addition of GDB server monitor command 'v.info open_fds' that gives the - list of open file descriptors and additional details. + - In all cases, the maximum number of sectors in the translation + cache can be controlled by the new flag --num-transtab-sectors. - - Optional message in the 'v.info n_errs_found' monitor command (e.g. - 'v.info n_errs_found test 1234 finished'), allowing to have - a comment string in the process output, separating errors of different - tests (or test phases). +* Changes in how debug info (line numbers, etc) is read: - - Addition of GDB server monitor command 'v.info execontext' that shows - information about the stack traces recorded by Valgrind. - This can be used to analyse one possible cause of Valgrind high - memory usage for some programs. + - Valgrind no longer temporarily mmaps the entire object to read + from it. Instead, reading is done through a small fixed sized + buffer. This avoids virtual memory usage spikes when Valgrind + reads debuginfo from large shared objects. - - Addition of GDB server monitor command - 'v.do expensive_sanity_check_general' that checks the sanity - of various Valgrind aspects, including the Valgrind heap. + - A new experimental remote debug info server. Valgrind can read + debug info from a different machine (typically, a build host) + where debuginfo objects are stored. This can save a lot of time + and hassle when running Valgrind on resource-constrained targets + (phones, tablets) when the full debuginfo objects are stored + somewhere else. This is enabled by the --debuginfo-server= + option. - - The list of used suppressions (shown when giving the -v option) - now gives the filename and line number where the suppression is defined. + - Consistency checking between main and debug objects can be + disabled using the --allow-mismatched-debuginfo option. - - remote debuginfo server + overhaul of debuginfo reading +* Stack unwinding by stack scanning, on ARM. Unwinding by stack + scanning can recover stack traces in some cases when the normal + unwind mechanisms fail. Stack scanning is best described as "a + nasty, dangerous and misleading hack" and so is disabled by default. + Use --unw-stack-scan-thresh and --unw-stack-scan-frames to enable + and control it. - - some fixes for OSX 10.8 +* Detection and merging of recursive stack frame cycles. When your + program has recursive algorithms, this limits the memory used by + Valgrind for recorded stack traces and avoids recording + uninteresting repeated calls. This is controlled by the command + line option --merge-recursive-frame and by the monitor command + "v.set merge-recursive-frames". - - partial-loads-ok now works for 16 and 32 byte loads - and in general improved handling of vectorised code on Memcheck +* New and modified GDB server monitor features: - - unwind-by-stack-scan for ARM + - valgrind.h has a new client request, VALGRIND_MONITOR_COMMAND, + that can be used to execute gdbserver monitor commands from the + client program. + - A new monitor command, "v.info open_fds", that gives the list of + open file descriptors and additional details. + + - An optional message in the "v.info n_errs_found" monitor command, + for example "v.info n_errs_found test 1234 finished", allowing a + comment string to be added to the process output, perhaps for the + purpose of separating errors of different tests or test phases. + + - A new monitor command "v.info execontext" that shows information + about the stack traces recorded by Valgrind. + + - A new monitor command "v.do expensive_sanity_check_general" to run + some internal consistency checks. + +* New flag --sigill-diagnostics to control whether a diagnostic + message is printed when the JIT encounters an instruction it can't + translate. The actual behavior -- delivery of SIGILL to the + application -- is unchanged. * ==================== FIXED BUGS ==================== @@ -112,593 +170,209 @@ To see details of a given bug, visit https://bugs.kde.org/show_bug.cgi?id=XXXXXX where XXXXXX is the bug number as listed below. -v = verified fixed in 3_8_BRANCH -m = merged into 3_8_BRANCH -[390] = fixed in trunk (for 3.9.0) -[381] = fixed in trunk and in 3_8_BRANCH, for 3.8.1 -[382] = fixed in trunk and needs to be made available for 3.8.2 too -
