Currently this object contains two (public) thread-local objects: a LLAPRRootPool and a LLVolatileAPRPool. The first is the general memory pool used by this thread (and this thread alone), while the second is intended for short lived memory allocations (needed for APR). The advantages of not mixing those two is that the latter is used most frequently, and as a result of it's nature can be destroyed and reconstructed on a "regular" basis. This patch adds LLAPRPool (completely replacing the old one), which is a wrapper around apr_pool_t* and has complete thread-safity checking. Whenever an apr call requires memory for some resource, a memory pool in the form of an LLAPRPool object can be created with the same life-time as this resource; assuring clean up of the memory no sooner, but also not much later than the life-time of the resource that needs the memory. Many, many function calls and constructors had the pool parameter simply removed (it is no longer the concern of the developer, if you don't write code that actually does an libapr call then you are no longer bothered with memory pools at all). However, I kept the notion of short-lived and long-lived allocations alive (see my remark in the jira here: https://jira.secondlife.com/browse/STORM-864?focusedCommentId=235356&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-235356 which requires that the LLAPRFile API needs to allow the user to specify how long they think a file will stay open. By choosing 'short_lived' as default for the constructor that immediately opens a file, the number of instances where this needs to be specified is drastically reduced however (obviously, any automatic LLAPRFile is short lived). *** Addressed Boroondas remarks in https://codereview.secondlife.com/r/99/ regarding (doxygen) comments. This patch effectively only changes comments. Includes some 'merge' stuff that ended up in llvocache.cpp (while starting as a bug fix, now only resulting in a cleanup). *** Added comment 'The use of apr_pool_t is OK here'. Added this comment on every line where apr_pool_t is correctly being used. This should make it easier to spot (future) errors where someone started to use apr_pool_t; you can just grep all sources for 'apr_pool_t' and immediately see where it's being used while LLAPRPool should have been used. Note that merging this patch is very easy: If there are no other uses of apr_pool_t in the code (one grep) and it compiles, then it will work. *** Second Merge (needed to remove 'delete mCreationMutex' from LLImageDecodeThread::~LLImageDecodeThread). *** Added back #include . Apparently that is needed on libapr version 1.2.8., the version used by Linden Lab, for calls to apr_queue_*. This is a bug in libapr (we also include , that is fixed in (at least) 1.3.7. Note that 1.2.8 is VERY old. Even 1.3.x is old. *** License fixes (GPL -> LGPL). And typo in comments. Addresses merov's comments on the review board. *** Added Merov's compile fixes for windows. --- indra/llcommon/CMakeLists.txt | 3 + indra/llcommon/llapp.cpp | 4 - indra/llcommon/llapr.cpp | 445 ++++++------------------------- indra/llcommon/llapr.h | 107 ++------ indra/llcommon/llaprpool.cpp | 202 ++++++++++++++ indra/llcommon/llaprpool.h | 256 ++++++++++++++++++ indra/llcommon/llcommon.cpp | 13 - indra/llcommon/llcommon.h | 2 - indra/llcommon/llerror.cpp | 3 + indra/llcommon/llerror.h | 1 - indra/llcommon/llfixedbuffer.cpp | 3 +- indra/llcommon/llscopedvolatileaprpool.h | 52 ++++ indra/llcommon/llthread.cpp | 151 +++++------ indra/llcommon/llthread.h | 124 +++++++-- indra/llcommon/llthreadsafequeue.cpp | 15 +- indra/llcommon/llthreadsafequeue.h | 16 +- indra/llcommon/llworkerthread.cpp | 8 +- indra/llcommon/llworkerthread.h | 3 +- 18 files changed, 793 insertions(+), 615 deletions(-) create mode 100644 indra/llcommon/llaprpool.cpp create mode 100644 indra/llcommon/llaprpool.h create mode 100644 indra/llcommon/llscopedvolatileaprpool.h (limited to 'indra/llcommon') diff --git a/indra/llcommon/CMakeLists.txt b/indra/llcommon/CMakeLists.txt index 9342a22d46..d5b0a67533 100644 --- a/indra/llcommon/CMakeLists.txt +++ b/indra/llcommon/CMakeLists.txt @@ -32,6 +32,7 @@ set(llcommon_SOURCE_FILES llallocator_heap_profile.cpp llapp.cpp llapr.cpp + llaprpool.cpp llassettype.cpp llavatarname.cpp llbase32.cpp @@ -80,6 +81,7 @@ set(llcommon_SOURCE_FILES llrand.cpp llrefcount.cpp llrun.cpp + llscopedvolatileaprpool.h llsd.cpp llsdserialize.cpp llsdserialize_xml.cpp @@ -121,6 +123,7 @@ set(llcommon_HEADER_FILES llavatarname.h llapp.h llapr.h + llaprpool.h llassettype.h llassoclist.h llavatarconstants.h diff --git a/indra/llcommon/llapp.cpp b/indra/llcommon/llapp.cpp index 39daefd1ad..e5bd2bfa3d 100644 --- a/indra/llcommon/llapp.cpp +++ b/indra/llcommon/llapp.cpp @@ -136,10 +136,6 @@ void LLApp::commonCtor() mOptions.append(sd);

(per Monty code review) The notion of storing LLMemoryInfo data both as an LLSD::Map and an LLSD::Array of pair arrays arose from a (possibly misguided) desire to continue producing stats output into the viewer log in the same order it always used to be produced. There is no evidence that anyone cares about the order of those stats in the log; there is no other use case for preserving order. At Monty's recommendation, eliminate generating and storing the array-of-pair-arrays form: directly store LLSD::Map. --- indra/llcommon/llsys.cpp | 72 ++++++++++++++++-------------------------------- indra/llcommon/llsys.h | 24 ++++------------ 2 files changed, 30 insertions(+), 66 deletions(-) (limited to 'indra/llcommon') diff --git a/indra/llcommon/llsys.cpp b/indra/llcommon/llsys.cpp index ebdef56c2a..99e61433c6 100644 --- a/indra/llcommon/llsys.cpp +++ b/indra/llcommon/llsys.cpp @@ -647,13 +647,13 @@ void LLCPUInfo::stream(std::ostream& s) const s << "->mCPUString: " << mCPUString << std::endl; } -// Helper class for LLMemoryInfo: accumulate stats in the array-of-pair-arrays -// form we store for LLMemoryInfo::getStatsArray(). -class StatsArray +// Helper class for LLMemoryInfo: accumulate stats in the form we store for +// LLMemoryInfo::getStatsMap(). +class Stats { public: - StatsArray(): - mStats(LLSD::emptyArray()) + Stats(): + mStats(LLSD::emptyMap()) {} // Store every integer type as LLSD::Integer. @@ -661,7 +661,7 @@ public: void add(const LLSD::String& name, const T& value, typename boost::enable_if >::type* = 0) { - mStats.append(LLSDArray(name)(LLSD::Integer(value))); + mStats[name] = LLSD::Integer(value); } // Store every floating-point type as LLSD::Real. @@ -669,13 +669,13 @@ public: void add(const LLSD::String& name, const T& value, typename boost::enable_if >::type* = 0) { - mStats.append(LLSDArray(name)(LLSD::Real(value))); + mStats[name] = LLSD::Real(value); } // Hope that LLSD::Date values are sufficiently unambiguous. void add(const LLSD::String& name, const LLSD::Date& value) { - mStats.append(LLSDArray(name)(value)); + mStats[name] = value; } LLSD get() const { return mStats; } @@ -792,7 +792,7 @@ void LLMemoryInfo::getAvailableMemoryKB(U32& avail_physical_mem_kb, U32& avail_v #if LL_WINDOWS // Sigh, this shouldn't be a static method, then we wouldn't have to // reload this data separately from refresh() - LLSD statsMap(loadStatsMap(loadStatsArray())); + LLSD statsMap(loadStatsMap()); avail_physical_mem_kb = statsMap["Avail Physical KB"].asInteger(); avail_virtual_mem_kb = statsMap["Avail Virtual KB"].asInteger(); @@ -884,16 +884,11 @@ void LLMemoryInfo::stream(std::ostream& s) const // introducer line, then read subsequent lines, etc... std::string pfx(LLError::utcTime() + " "); - // Most of the reason we even store mStatsArray is to preserve the - // original order in which we obtained these stats from the OS.

Instead, accept script text, write a temporary script file in a system- dependent temp directory, ask Python to run that script and delete the file.
