From cde5101eb15b24519e89fa500fe37038bc8e2201 Mon Sep 17 00:00:00 2001 From: art-snake Date: Thu, 15 Sep 2016 14:11:09 -0700 Subject: Fix memory leaking on ClosePage. CFX_FontCache refactoring: after this CL: Only one global CFX_FontCache used. Any cached items from it, are released, when its are not used. BUG=79367,48791 The fonts was not cleared after unloading pages. Test pdf: http://www.nasa.gov/pdf/750614main_NASA_FY_2014_Budget_Estimates-508.pdf For this file, we have ~5 fonts per page, which equal ~1 Mb per page. In this PDF we have 670 pages, as result after slow scrolling(reading) full document we have ~600 Mb fonts data in memory. memory usage of PDF Plugin: before this CL: ~660 Mb after this CL: ~100 Mb Review-Url: https://codereview.chromium.org/2158023002 --- core/fxge/apple/fx_quartz_device.cpp | 13 +++++-------- 1 file changed, 5 insertions(+), 8 deletions(-) (limited to 'core/fxge/apple/fx_quartz_device.cpp') diff --git a/core/fxge/apple/fx_quartz_device.cpp b/core/fxge/apple/fx_quartz_device.cpp index 400e29085c..6a0260b1d6 100644 --- a/core/fxge/apple/fx_quartz_device.cpp +++ b/core/fxge/apple/fx_quartz_device.cpp @@ -13,7 +13,6 @@ #include "core/fxcrt/include/fx_memory.h" #include "core/fxge/dib/dib_int.h" #include "core/fxge/ge/fx_text_int.h" -#include "core/fxge/include/cfx_fontcache.h" #include "core/fxge/include/cfx_gemodule.h" #include "core/fxge/include/cfx_graphstatedata.h" #include "core/fxge/include/cfx_pathdata.h" @@ -746,7 +745,6 @@ FX_BOOL CFX_QuartzDeviceDriver::CG_DrawGlyphRun( int nChars, const FXTEXT_CHARPOS* pCharPos, CFX_Font* pFont, - CFX_FontCache* pCache, const CFX_Matrix* pGlyphMatrix, const CFX_Matrix* pObject2Device, FX_FLOAT font_size, @@ -812,7 +810,6 @@ FX_BOOL CFX_QuartzDeviceDriver::CG_DrawGlyphRun( FX_BOOL CFX_QuartzDeviceDriver::DrawDeviceText(int nChars, const FXTEXT_CHARPOS* pCharPos, CFX_Font* pFont, - CFX_FontCache* pCache, const CFX_Matrix* pObject2Device, FX_FLOAT font_size, uint32_t color) { @@ -832,8 +829,8 @@ FX_BOOL CFX_QuartzDeviceDriver::DrawDeviceText(int nChars, while (i < nChars) { if (pCharPos[i].m_bGlyphAdjust || font_size < 0) { if (i > 0) { - ret = CG_DrawGlyphRun(i, pCharPos, pFont, pCache, nullptr, - pObject2Device, font_size, color); + ret = CG_DrawGlyphRun(i, pCharPos, pFont, nullptr, pObject2Device, + font_size, color); if (!ret) { RestoreState(false); return ret; @@ -849,8 +846,8 @@ FX_BOOL CFX_QuartzDeviceDriver::DrawDeviceText(int nChars, char_pos->m_AdjustMatrix[0], char_pos->m_AdjustMatrix[1], char_pos->m_AdjustMatrix[2], char_pos->m_AdjustMatrix[3], 0, 0); } - ret = CG_DrawGlyphRun(1, char_pos, pFont, pCache, &glphy_matrix, - pObject2Device, font_size, color); + ret = CG_DrawGlyphRun(1, char_pos, pFont, &glphy_matrix, pObject2Device, + font_size, color); if (!ret) { RestoreState(false); return ret; @@ -864,7 +861,7 @@ FX_BOOL CFX_QuartzDeviceDriver::DrawDeviceText(int nChars, } } if (i > 0) { - ret = CG_DrawGlyphRun(i, pCharPos, pFont, pCache, nullptr, pObject2Device, + ret = CG_DrawGlyphRun(i, pCharPos, pFont, nullptr, pObject2Device, font_size, color); } RestoreState(false); -- cgit v1.2.3
