2022-11-03DRTVWR-575: Fix llcommon assumptions that size_t fits in 4 bytes.Nat Goodspeed
It's a little distressing how often we have historically coded S32 or U32 to pass a length or index. There are more such assumptions in other viewer subdirectories, but this is a start.

2020-03-25DRTVWR-494: Use std::thread::id for LLThread::currentID().Nat Goodspeed
LLThread::currentID() used to return a U32, a distinct unsigned value incremented by explicitly constructing LLThread or by calling LLThread:: registerThreadID() early in a thread launched by other means. The latter imposed an unobvious requirement on new code based on std::thread. Using std::thread::id instead delegates to the compiler/library the problem of distinguishing threads launched by any means. Change lots of explicit U32 declarations. Introduce LLThread::id_t typedef to avoid having to run around fixing uses again if we later revisit this decision. LLMutex, which stores an LLThread::id_t, wants a distinguished value meaning NO_THREAD, and had an enum with that name. But as std::thread::id promises that the default-constructed value is distinct from every valid value, NO_THREAD becomes unnecessary and goes away. Because LLMutex now stores LLThread::id_t instead of U32, make llmutex.h #include "llthread.h" instead of the other way around. This makes LLMutex an incomplete type within llthread.h, so move LLThread::lockData() and unlockData() to the .cpp file. Similarly, remove llrefcount.h's #include "llmutex.h" to break circularity; instead forward-declare LLMutex. It turns out that a number of source files assumed that #include "llthread.h" would get the definition for LLMutex. Sprinkle #include "llmutex.h" as needed. In the SAFE_SSL code in llcorehttp/httpcommon.cpp, there's an ssl_thread_id() callback that returns an unsigned long to the SSL library. When LLThread:: currentID() was U32, we could simply return that. But std::thread::id is very deliberately opaque, and can't be reinterpret_cast to unsigned long. Fortunately it can be hashed because std::hash is specialized with that type.

2011-02-05Introduces a LLThreadLocalData class that can beAleric Inglewood
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). *** 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 <apr_pools.h>. 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 <apr_queue.h>, 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.
