Review request for Viewer. Summary ------- Please see http://jira.secondlife.com/browse/STORM-864 I made a mercurial repository available for testing here: hg clone https://bitbucket.org/aleric/viewer-development-storm-864 >From the commit message: Introduces a LLThreadLocalData class that can be accessed through the static LLThread::tldata(). 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). This addresses bug STORM-864. http://jira.secondlife.com/browse/STORM-864 Diffs ----- doc/contributions.txt 422f636c3343 indra/llaudio/llaudioengine_fmod.cpp 422f636c3343 indra/llaudio/llvorbisencode.cpp 422f636c3343 indra/llcharacter/llbvhloader.cpp 422f636c3343 indra/llcharacter/llkeyframemotionparam.cpp 422f636c3343 indra/llcharacter/llstatemachine.cpp 422f636c3343 indra/llcommon/CMakeLists.txt 422f636c3343 indra/llcommon/llapp.cpp 422f636c3343 indra/llcommon/llapr.h 422f636c3343 indra/llcommon/llapr.cpp 422f636c3343 indra/llcommon/llaprpool.h PRE-CREATION indra/llcommon/llaprpool.cpp PRE-CREATION indra/llcommon/llcommon.h 422f636c3343 indra/llcommon/llcommon.cpp 422f636c3343 indra/llcommon/llerror.h 422f636c3343 indra/llcommon/llerror.cpp 422f636c3343 indra/llcommon/llfixedbuffer.cpp 422f636c3343 indra/llcommon/llscopedvolatileaprpool.h PRE-CREATION indra/llcommon/llthread.h 422f636c3343 indra/llcommon/llthread.cpp 422f636c3343 indra/llcommon/llthreadsafequeue.h 422f636c3343 indra/llcommon/llthreadsafequeue.cpp 422f636c3343 indra/llcommon/llworkerthread.h 422f636c3343 indra/llcommon/llworkerthread.cpp 422f636c3343 indra/llcrashlogger/llcrashlogger.cpp 422f636c3343 indra/llimage/llimage.cpp 422f636c3343 indra/llimage/llimagedimensionsinfo.cpp 422f636c3343 indra/llimage/llimagej2c.cpp 422f636c3343 indra/llimage/llimageworker.h 422f636c3343 indra/llimage/llimageworker.cpp 422f636c3343 indra/llmath/llvolumemgr.cpp 422f636c3343 indra/llmessage/llares.cpp 422f636c3343 indra/llmessage/llcurl.cpp 422f636c3343 indra/llmessage/lliohttpserver.h 422f636c3343 indra/llmessage/lliohttpserver.cpp 422f636c3343 indra/llmessage/lliosocket.h 422f636c3343 indra/llmessage/lliosocket.cpp 422f636c3343 indra/llmessage/llmail.h 422f636c3343 indra/llmessage/llmail.cpp 422f636c3343 indra/llmessage/llpumpio.h 422f636c3343 indra/llmessage/llpumpio.cpp 422f636c3343 indra/llmessage/llurlrequest.cpp 422f636c3343 indra/llmessage/message.cpp 422f636c3343 indra/llmessage/tests/networkio.h 422f636c3343 indra/llplugin/llplugininstance.h 422f636c3343 indra/llplugin/llplugininstance.cpp 422f636c3343 indra/llplugin/llpluginmessagepipe.cpp 422f636c3343 indra/llplugin/llpluginprocesschild.cpp 422f636c3343 indra/llplugin/llpluginprocessparent.h 422f636c3343 indra/llplugin/llpluginprocessparent.cpp 422f636c3343 indra/llplugin/llpluginsharedmemory.h 422f636c3343 indra/llplugin/llpluginsharedmemory.cpp 422f636c3343 indra/llplugin/slplugin/slplugin.cpp 422f636c3343 indra/llvfs/lllfsthread.cpp 422f636c3343 indra/llvfs/llvfs.cpp 422f636c3343 indra/media_plugins/gstreamer010/llmediaimplgstreamer.h 422f636c3343 indra/media_plugins/gstreamer010/llmediaimplgstreamer_syms.cpp 422f636c3343 indra/media_plugins/webkit/linux_volume_catcher.cpp 422f636c3343 indra/newview/llappviewer.h 422f636c3343 indra/newview/llappviewer.cpp 422f636c3343 indra/newview/llappviewerlinux.cpp 422f636c3343 indra/newview/llappviewerlinux_api_dbus.cpp 422f636c3343 indra/newview/llappviewermacosx.cpp 422f636c3343 indra/newview/llfloateranimpreview.cpp 422f636c3343 indra/newview/llmainlooprepeater.cpp 422f636c3343 indra/newview/lltexturecache.h 422f636c3343 indra/newview/lltexturecache.cpp 422f636c3343 indra/newview/lltexturefetch.cpp 422f636c3343 indra/newview/llviewermenufile.cpp 422f636c3343 indra/newview/llvoavatar.cpp 422f636c3343 indra/newview/llvocache.h 422f636c3343 indra/newview/llvocache.cpp 422f636c3343 indra/newview/llvoicevivox.cpp 422f636c3343 indra/newview/llwatchdog.cpp 422f636c3343 indra/newview/tests/llworldmap_test.cpp 422f636c3343 indra/test/lltemplatemessagebuilder_tut.cpp 422f636c3343 indra/test/message_tut.cpp 422f636c3343 indra/test/test.cpp 422f636c3343 indra/test_apps/llplugintest/llmediaplugintest.cpp 422f636c3343 indra/viewer_components/updater/llupdateinstaller.cpp 422f636c3343 Diff: http://codereview.secondlife.com/r/99/diff Testing ------- Compiles and viewer functions normally. The new classes (LLAPRPool, LLThreadLocalData) and the LLAPRFile changes have been tested a lot more extensive, since they have been used as-is for months in imprudence and before that in my own viewer (since April). However, the patch contains changes to code elsewhere (to adapt it to the new API) that is rather new in this source tree. Note that changes with regard to LLAPRFile already have been in Snowglobe since version 1.1 (with some minor changes) including the method used to make thread-local data available. Thanks, Aleric
