2020-06-26Handle uno_threadpool_dispose in parallel with uno_threadpool_putJobStephan Bergmann
While tracking down the issue discussed in the commit message of 78dc7d982b65c1843a288b80da83f8766e85d0cf "Remove a potentially already enqueued response when a bridge is disposed", it occurred to me that there should be a race in those uno_threadpool_putJob( bridge_->getThreadPool(), ...); calls in binaryurp/source/reader.cxx, when the bridge gets disposed (through some other thread) between the time the bridge_->getThreadPool() call checks for the bridge being disposed (in which case it would throw a DisposedException) and the actual uno_threadpool_putJob call. I tried to catch that with a previous incarnation of this change (<https://gerrit.libreoffice.org/c/core/+/96120/1> "Jenkins Slides Through the Tiny Window"), but couldn't---presumably because this race would be very rare after all, and the issue I was chasing turned out to be caused by something different anyway. Nevertheless, I wanted to address this potential race now. We can only reliably check for disposed'ness after having locked ThreadPool's m_mutex in uno_threadpool_putJob -> ThreadPool::addJob, but at which time we can no longer indicate this condition to the caller---uno_threapool_putJob is part of the stable URE interface, has a void return type, and should not throw any exceptions as it is a C function. However, if the bridge gets disposed, any threads that would wait for this job (in cppu_threadpool::JobQueue::enter, either from cppu_threadpool::ORequestThread::run waiting to process new incoming calls, or from a bridge's call to uno_threadpool_enter waiting for a respose to an outgoing call) should already learn about the bridge being disposed by falling out of cppu_threadpool::JobQueue::enter with a null return value. So it should be OK if uno_threadpool_putJob silently discards the job in that case.

2020-06-16Use the saner std::condition_variable semantics for JobQueue::m_cndWaitStephan Bergmann
This avoids the need for the tricky osl::Condition::reset calls. For example, the first one (in the "disposed !" case) had been added with 2a3ed89284890615ad4bce57be55ba558351cde1 "sb132: #i112448# proper clean up in JobQueue::enter (patch by olistraub)" as > if( 0 == m_lstCallstack.front() ) > { > // disposed ! > + if( m_lstJob.empty() ) > + { > + osl_resetCondition( m_cndWait ); > + } > break; > } > and then change to > if( 0 == m_lstCallstack.front() ) > { > // disposed ! > - if( m_lstJob.empty() ) > + if( m_lstJob.empty() > + && (m_lstCallstack.empty() > + || m_lstCallstack.front() != 0) ) > { > osl_resetCondition( m_cndWait ); > } with cba3ac1eab7acaf8e6efd7a00eee7c5e969fc49b "Avoid deadlocks when disposing recursive JobQueue::enter", which prevented the reset from ever hapening (because m_lstCallstack.front() cannot both be zero and non-zero here at the same time). The std::condition_variable semantics nicely avoid any reasoning whether or not a reset would be necessary here.

2020-06-15Remove a potentially already enqueued response when a bridge is disposedStephan Bergmann
...while a remote call is in progress. Otherwise, if the same thread later makes another remote call (through another bridge), it would erroneously pair the repsonse for the disposed call with the second call. UITest_calc_demo started to fail that way occasionally, presumably after 77445e201c45e5593761e8399c32f80eea2178a4 "Make Chart Creation Wizard async", but for reasons rather unrelated to the contents of that commit. What apparently happened is that in one test's tearDown, the bridge between the Python and the soffice process happened to be disposed during the XDesktop::terminate call from Python's main thread, so that the response (of type BOOLEAN) remained in the JobQueue. Then during the next test's setUp, XUnoUrlResolver::resolve from Python's main thread would internally make a remote queryInterface call for the initial StarOffice.ComponentContext object, which returns an ANY of either VOID or XInterface type. But that call was then mis-matched with the leftover BOOLEAN response, causing failure. I was able to reproduce that reliably on Linux with a local hack of > diff --git a/cppu/source/threadpool/jobqueue.cxx b/cppu/source/threadpool/jobqueue.cxx > index 6c9324521f40..a87770bf8935 100644 > --- a/cppu/source/threadpool/jobqueue.cxx > +++ b/cppu/source/threadpool/jobqueue.cxx > @@ -71,6 +71,7 @@ namespace cppu_threadpool { > } > > m_cndWait.wait(); > + timespec ms{0, 1000000}; nanosleep(&ms, nullptr); > > struct Job job={nullptr,nullptr}; > { introducing a sleep, so that other threads have a higher chance to dispose the bridge (when the call being processed here is that XDesktop::dispose) after the successful wait() but before the response is processed.

2019-11-22Extend loplugin:external to warn about classesStephan Bergmann
...following up on 314f15bff08b76bf96acf99141776ef64d2f1355 "Extend loplugin:external to warn about enums". Cases where free functions were moved into an unnamed namespace along with a class, to not break ADL, are in: filter/source/svg/svgexport.cxx sc/source/filter/excel/xelink.cxx sc/source/filter/excel/xilink.cxx svx/source/sdr/contact/viewobjectcontactofunocontrol.cxx All other free functions mentioning moved classes appear to be harmless and not give rise to (silent, even) ADL breakage. (One remaining TODO in compilerplugins/clang/external.cxx is that derived classes are not covered by computeAffectedTypes, even though they could also be affected by ADL-breakage--- but don't seem to be in any acutal case across the code base.) For friend declarations using elaborate type specifiers, like class C1 {}; class C2 { friend class C1; }; * If C2 (but not C1) is moved into an unnamed namespace, the friend declaration must be changed to not use an elaborate type specifier (i.e., "friend C1;"; see C++17 [namespace.memdef]/3: "If the name in a friend declaration is neither qualified nor a template-id and the declaration is a function or an elaborated-type-specifier, the lookup to determine whether the entity has been previously declared shall not consider any scopes outside the innermost enclosing namespace.") * If C1 (but not C2) is moved into an unnamed namespace, the friend declaration must be changed too, see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71882> "elaborated-type-specifier friend not looked up in unnamed namespace". Apart from that, to keep changes simple and mostly mechanical (which should help avoid regressions), out-of-line definitions of class members have been left in the enclosing (named) namespace. But explicit specializations of class templates had to be moved into the unnamed namespace to appease <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92598> "explicit specialization of template from unnamed namespace using unqualified-id in enclosing namespace". Also, accompanying declarations (of e.g. typedefs or static variables) that could arguably be moved into the unnamed namespace too have been left alone. And in some cases, mention of affected types in blacklists in other loplugins needed to be adapted. And sc/qa/unit/mark_test.cxx uses a hack of including other .cxx, one of which is sc/source/core/data/segmenttree.cxx where e.g. ScFlatUInt16SegmentsImpl is not moved into an unnamed namespace (because it is declared in sc/inc/segmenttree.hxx), but its base ScFlatSegmentsImpl is. GCC warns about such combinations with enabled-by-default -Wsubobject-linkage, but "The compiler doesn’t give this warning for types defined in the main .C file, as those are unlikely to have multiple definitions." (<https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Warning-Options.html>) The warned-about classes also don't have multiple definitions in the given test, so disable the warning when including the .cxx.

2019-11-08Avoid repeated calls cppu::detail::loadModule -> osl_getModuleURLFromAddressStephan Bergmann

On the other hand, this change reduces the number of calls to osl_getModuleURLFromAddress by computing the base URI in cppu::detail::loadModule only once. For my local Linux --enable-dbgutil build, for `instdir/program/soffice '109340 class14.ppt'` and then exiting LO again (with the document attached at <https://bugs.documentfoundation.org/show_bug.cgi?id=121740#c0>), this reduces the number of calls to osl_getModuleURLFromAddress from 3775 to 22. (Many of those calls originated from cppu::getCaughtException or cppu::throwException, as in osl_getModuleURLFromAddress osl_getModuleURLFromFunctionAddress osl::Module::getUrlFromAddress osl_loadModuleRelative osl::Module::loadRelative cppu::detail::loadModule cppu::loadModule cppu::loadExternalMapping uno_getMapping com::sun::star::uno::Mapping::Mapping cppu::throwException .) Unfortunately, this needs to duplicate functionality from osl_loadModuleRelative (sal/osl/all/loadmodulerelative.cxx) somewhat, as the stable SAL interface only offers functionality to load relative to a given function, not relative to a given base URI. (And extending the stable SAL interface for this one use is not worth the maintenance costs.)

...that had been missing because the plugin didn't implement postRun, so it didn't report anything when run as part of the shared plugin. (But did report the expected warnings when run as a standalone plugin during CompilerTest_compilerplugins_clang.) Most fixes are straightforward. A noteworthy one is PreparedStatement::setBytes in connectivity/source/drivers/postgresql/pq_preparedstatement.cxx: The old preallocation of a 20 character OStringBuffer might have prevented buf.append( reinterpret_cast<char *>(escapedString), len -1 ); from potentially throwing std::bad_alloc, which would have caused escapedString to be leaked. Even though that 20-character preallocation was likely just random junk and not meant to address the potential leak, lets address it now.

2019-09-03Silence -fsanitize=object-size in --enable-optimized buildsStephan Bergmann
<http://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html#available-checks> (as of recent LLVM trunk towards LLVM 10) states: "-fsanitize=object-size: An attempt to potentially use bytes which the optimizer can determine are not part of the object being accessed. This will also detect some types of undefined behavior that may not directly access memory, but are provably incorrect given the size of the objects involved, such as invalid downcasts and calling methods on invalid pointers. These checks are made in terms of __builtin_object_size, and consequently may be able to detect more problems at higher optimization levels." A `make check screenshot` with --enabled-optimized runs into two such issues that were not diagnosed with --disable-optimized, in both cases because a struct with an "idiomatic trailing dynamic array member" (statically declared to be an array of size 1) is allocated without any space for that array member, as the dynamic array size is 0 in the specific case: * For > [CUT] sc_ucalc > cppu/source/uno/copy.hxx:46:19: runtime error: member access within address 0x6020001aaa70 with insufficient space for an object of type 'uno_Sequence' (aka '_sal_Sequence') > 0x6020001aaa70: note: pointer points here > 2b 00 80 6a be be be be be be be be 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > ^ > #0 in cppu::allocSeq(int, int) at cppu/source/uno/copy.hxx:46:19 (instdir/program/libuno_cppu.so.3 +0x41f03f) > #1 in uno_type_sequence_reference2One at cppu/source/uno/sequence.cxx:813:20 (instdir/program/libuno_cppu.so.3 +0x41f03f) [...] the call to pNew = allocSeq( 0, 0 ); in uno_type_sequence_reference2One is inlined, so sal_uInt32 nSize = calcSeqMemSize( nElementSize, nElements ); in allocSeq is known to be too small. * For > testSignatureLineODF::TestBody finished in: 2044ms > engine-gpg.c:302:6: runtime error: member access within address 0x604001f24f10 with insufficient space for an object of type 'struct arg_and_data_s' > 0x604001f24f10: note: pointer points here > 6e 01 00 26 be be be be be be be be be be be be be be be be be be be be be be be be be be be be > ^ > #0 in add_data at workdir/UnpackedTarball/gpgmepp/src/engine-gpg.c:302:6 (instdir/program/libgpgme.so.11 +0x120c2b) [...] > make[1]: *** [solenv/gbuild/CppunitTest.mk:114: workdir/CppunitTest/xmlsecurity_signing.test] Error 1 the a = malloc (sizeof *a - 1); is apparently detected to be too small only with optimization enabled. In both cases, the solution is to operate on the too-small dynamically allocated object via a reinterpret_cast'ed pointer to some newly introduced "struct prefix" type.
