From 3ca3ea75c333078013914e174564340f894573e2 Mon Sep 17 00:00:00 2001 From: Frederick Martian Date: Sat, 25 Oct 2025 17:08:35 +0200 Subject: Add a new static function LLFile::size() to determine the size of a file_name. Replace LLAPRFile::remove(), LLAPRFile::size() and LLAPRFile::isExist() with according functions from LLFile and retire these LLAPRFile methods and the never used LLAPRFile::rename(), LLAPRFile::makeDir() and LLAPRFile::removeDir() functions. Also clean up remarks about the threading safety of the APRCachePool, which is not used in these locations anymore. --- indra/newview/lltexturecache.cpp | 38 ++++++++++++++++---------------------- 1 file changed, 16 insertions(+), 22 deletions(-) (limited to 'indra/newview/lltexturecache.cpp') diff --git a/indra/newview/lltexturecache.cpp b/indra/newview/lltexturecache.cpp index 1a7ce74ccc..e59cf70177 100644 --- a/indra/newview/lltexturecache.cpp +++ b/indra/newview/lltexturecache.cpp @@ -180,7 +180,7 @@ private: bool LLTextureCacheLocalFileWorker::doRead() { LL_PROFILE_ZONE_SCOPED_CATEGORY_TEXTURE; - S32 local_size = LLAPRFile::size(mFileName, mCache->getLocalAPRFilePool()); + S32 local_size = (S32)LLFile::size(mFileName); if (local_size > 0 && mFileName.size() > 4) { @@ -296,7 +296,7 @@ bool LLTextureCacheRemoteWorker::doRead() // Is it a JPEG2000 file? { local_filename = filename + ".j2c"; - local_size = LLAPRFile::size(local_filename, mCache->getLocalAPRFilePool()); + local_size = (S32)LLFile::size(local_filename); if (local_size > 0) { mImageFormat = IMG_CODEC_J2C; @@ -306,7 +306,7 @@ bool LLTextureCacheRemoteWorker::doRead() if (local_size == 0) { local_filename = filename + ".jpg"; - local_size = LLAPRFile::size(local_filename, mCache->getLocalAPRFilePool()); + local_size = (S32)LLFile::size(local_filename); if (local_size > 0) { mImageFormat = IMG_CODEC_JPEG; @@ -317,7 +317,7 @@ bool LLTextureCacheRemoteWorker::doRead() if (local_size == 0) { local_filename = filename + ".tga"; - local_size = LLAPRFile::size(local_filename, mCache->getLocalAPRFilePool()); + local_size = (S32)LLFile::size(local_filename); if (local_size > 0) { mImageFormat = IMG_CODEC_TGA; @@ -446,7 +446,7 @@ bool LLTextureCacheRemoteWorker::doRead() if (!done && (mState == BODY)) { std::string filename = mCache->getTextureFileName(mID); - S32 filesize = LLAPRFile::size(filename, mCache->getLocalAPRFilePool()); + S32 filesize = (S32)LLFile::size(filename); if (filesize && (filesize + TEXTURE_CACHE_ENTRY_SIZE) > mOffset) { @@ -891,7 +891,7 @@ bool LLTextureCache::isInLocal(const LLUUID& id) // Is it a JPEG2000 file? { local_filename = filename + ".j2c"; - local_size = LLAPRFile::size(local_filename, getLocalAPRFilePool()); + local_size = (S32)LLFile::size(local_filename); if (local_size > 0) { return true ; @@ -901,7 +901,7 @@ bool LLTextureCache::isInLocal(const LLUUID& id) // If not, is it a jpeg file? { local_filename = filename + ".jpg"; - local_size = LLAPRFile::size(local_filename, getLocalAPRFilePool()); + local_size = (S32)LLFile::size(local_filename); if (local_size > 0) { return true ; @@ -911,7 +911,7 @@ bool LLTextureCache::isInLocal(const LLUUID& id) // Hmm...
