Name: icu URL: http://site.icu-project.org/ Version: 52.1 License: MIT Security Critical: yes Description: This directory contains the source code of ICU 52.1 for C/C++ 1. It was obtained with the following: $ svn export --native-eol LF http://source.icu-project.org/repos/icu/icu/tags/release-52-1 icu52 The following directories we don't use are removed: - as_is - packaging - source/layout - source/layoutex - source/data/xml patches/configure.patch is applied to get runConfigureICU work in the icudata generation step without layout and layoutex directory by removing the corresponding Makefile's from ac_config variable. 2. Apply the following patch for platform related headers (putilimpl.h and others). - patches/putil.patch for Android, QNX and newlib(NaCl-newlib). Upstream bug for Android : http://bugs.icu-project.org/trac/ticket/10478 Upstream bug for QNX : http://bugs.icu-project.org/trac/ticket/10811 Upstream bug for newlib : http://bugs.icu-project.org/trac/ticket/10873 - patches/platform_nacl.patch to add U_PF_NATIVE_CLIENT Upstream bug : http://bugs.icu-project.org/trac/ticket/11033 3. Breakiterator patches - Apply patches/brkitr.patch * word.txt a. Move full stops (U+002E, U+FF0E) from MidNumLet to MidNum so that FQDN labels can be split at '.' b. Move fullwidth digits (U+FF10 - U+FF19) from Ideographic to Numeric. See http://unicode.org/cldr/trac/ticket/6555 * line.txt a. Use Japanese rules for all locales because Japanese tailoring only affects Japanese specific characters. See http://unicode.org/cldr/trac/ticket/3974 b. Minor changes in CL, OP and IS definitions to handle 'comma-variants' more consistenly. See http://unicode.org/cldr/trac/ticket/6557 c. Fix line breaking for Chinese characters and quotation marks See http://unicode.org/cldr/trac/ticket/4200 and http://crbug.com/39779 - Add a new file brklocal.mk (copied from brkfiles.mk) with line_ja.txt and word_POSIX.txt dropped from the build list. - Apply patches/khmer-dictbe.patch and put in a smaller Khmer dictionary (source/data/brkitr/khmerdict.txt) obtained from http://bugs.icu-project.org/trac/ticket/9451 - Add several common Chinese words that were dropped previously to source/data/cjdict/brkitr/cjdict.txt patch: patches/cjdict.patch upstream bug: http://bugs.icu-project.org/trac/ticket/10888 - android/brkitr.patch (to be applied for Android build only) : Do not use the C+J dictionary for Chinese/Japanese segmentation to reduce the data size. Adjust word.txt and a few other files. - source/data/brkitr/word_ja.txt (used only on Android) Added for Japanese-specific word-breaking without the C+J dictionary. 4. Converter changes : - convrtrs.txt : Replaced the original by our own that only lists encodings and aliases required by the WHATWG Encoding spec plus a few extra (see the file as to why). - Add source/data/mappings/ucmlocal.txt : to list only converters we need. - Add new tables per the WHATWG encoding standards for EUC-JP, Shift_JIS and all the single byte encodings. They're generated with scripts : scripts/{eucjp, sjis, single_byte}_gen.sh - uconv.patch a. ISO-2022-JP-[1-4] is dropped. b. SCSU, BOCU, ISCII, UTF-7, LMB, ibm42*, ISO-2022-{KR,CN*} and HZ-GB : converters and detectors are dropped leading to the ~100kB reduction in the code size. 5. Locale changes - patches/locale1.patch : a. Exemplar character set changes for zh*, ja + 9 Indian locales b. Minor fixes for Korean, a few Indic (AmPmMarkers) and others (datetime format) - Locale build configuration files: To include the full locale data for Chrome's UI languages and the minimum locale data for other locales, add reslocal.mk or {trns,sprep,rbnf,coll}local.mk files to source/data/{coll,curr,lang.locale,curr,region,translit,zone,rbnf,sprep}. This along with #8 (data.build.patch), #3 (brkiter) and #4 (converter) cuts down the data size by ~ 11MB. - Run scripts/trim_data.sh : About 2.1MB data size reduction. a. Trim the locale data for Chrome's UI langauges : locales, lang, region, currency b. Trim the locale data for non-UI languages to the bare minimum : ExemplarCharacters, LocaleScript, layout, and the name of the language for a locale in its native language. c. Remove the legacy Chinese character set-based collation (big5han/gb2312han) that don't make any sense and nobdoy uses. - android/patch_locale.sh (to be run for Android build only): a. Makes changes to source/data/{curr,region,lang} to exclude these data except the language and script names of zh_Hans and zh_Hant. b. Remove exemplar cities in timezone data (data/zone) c. Keep only the minimal calendar data in data/locales - Add tg.txt to source/data/locale source/data/lang to add the minimal locale data necessary for the spellchecker. In both directories, add tg.txt to reslocal.mk 6. Timezone data update - Grab the latest version of the following timezone data files and put them in source/data/misc. metaZones.txt timezoneTypes.txt windowsZones.txt zoneinfo64.txt As of August 2014, the latest version is 2014f and the above files are available at http://source.icu-project.org/repos/icu/data/trunk/tzdata/icunew/2014f/44/ 7. Transliterator customization - Also add css3transform.txt to source/data/trnslit. - Put the following line in trnslocal.mk TRANSLIT_SOURCE=css3transform.txt 8. Build-related changes - patches/wpo.patch Upstream bugs : http://bugs.icu-project.org/trac/ticket/8043 http://bugs.icu-project.org/trac/ticket/5701 - patches/vscomp.patch for building with Visual Studio on Windows. a. do not use WINDOWS_LOCALE_API in locmap.c b. do not redefine stringpiece::npos c. fix a Windows build failure with U_USING_ICU_NAMESPACE=0 upstream bug: http://bugs.icu-project.org/trac/ticket/10486 fixed in ICU 53) d. Explicitly use Windows 'A' API when argument is an LPSTR in wintz.c upstream bug : http://bugs.icu-project.org/trac/ticket/10870 - patches/data.build.patch : Remove unnecessary resources : invuca, unames, collator source, stringprep - patches/data.build.win.patch : Windows-only data build patch. - patches/clang_win.patch : Take care of 3 warnings from clang and MSVC 2013. upstream bug : http://bugs.icu-project.org/trac/ticket/11102 9. Pre-built data files are checked in with the following steps on Linux: a. Make a icu data build directory outside the Chromium source tree and cd to that directory. b. Run ${CHROME_ICU_TREE_TOP}/source/runConfigureICU Linux --disable-layout c. Run 'make' d. 'make' will fail in the 1st pass. Copy ${CHROME_ICU_TREE_TOP}/source/data/in/coll/invuca.icu to {BUILD_DIR_ROOT}/data/out/build/icudt52l/coll and re-run 'make' in {BUILD_DIR_ROOT}/data. e. 'make' will fail again when pkgdata looks for css3transform.res. Edit data/out/tmp/icudata.lst to replace 'css3transform.res' with 'root.res'. (see http://bugs.icu-project.org/trac/ticket/10570 ) and run 'make' again. - source/data/in/icudtl.dat : Built on Linux with all the patches above applied. icudt52l.dat is generated in {BUILD_DIR_ROOT}/data/out/tmp and copied to the above location with a version number (52) dropped. - {mac,linux}/icudtl_dat.S : Built on Linux with all the patches above (except android/brkitr.patch) applied and checked in. This file will be generated in {BUILD_DIR_ROOT}/data/out/tmp as icudt52l_dat.S, but '52' is dropped while copying. mac/icudtl_dat.S is identical to linux/icudtl_dat.S except for the header portion. With "linux/icudtl_dat.S" in its place, run scripts/make_mac_assembly.sh to generate it. - android/icudtl_dat.S : Built on Linux with all the patches above and android/brkitr.patch applied and android/patch_locale.sh executed. '52' is dropped from the name generated in the build tree. - android/icudtl.dat : Generated as icudt52l.dat in {BUILD_DIR_ROOT}/data/out/tmp along with icudt52l_dat.S and copied to the above location with '52' dropped in its name. - windows/icudt.dll (by default, we set icu_use_icu_data_flag to 1 and don't use this file.) a. check out a clean copy of icu52 from the upstream on Windows outside the Chrome tree. $ svn export --native-eol LF http://source.icu-project.org/repos/icu/icu/tags/release-52-1 ${SEPARATE_ICU_ROOT}/icu52 b. copy ${CHROME_ICU_ROOT}/source/data/in/icudtl.dat to ${SEPARATE_ICU_ROOT}/source/data/in/icudt52l.dat c. copy ${CHROME_ICU_ROOT}/source/data/makedata.mak to ${SEPARATE_ICU_ROOT}/source/data/makedata.mak c. In Visual Studio, open source/allinone/allinone.sln solution in ${SEPARATE_ICU_ROOT} d. Build 'makedata' target e. icudt52.dll will be generated in ${SEPARATE_ICU_ROOT}/bin f. Copy that icudt52.dll to ${CHROME_ICU_ROOT}/windows/icudt.dll and check that in. 10. Change export of U_ICUDATA_ENTRY_POINT from U_IMPORT to U_EXPORT. - patches/declspec.patch 11. Cherry-pick an upstream patch to fix a bug in bidi. - patches/bidi.patch - upstream bug : http://bugs.icu-project.org/trac/ticket/11054 12. Apply the following patches for regex - patches/regex.patch and patches/regex2.patch - upstream bugs : http://bugs.icu-project.org/trac/ticket/11369 http://bugs.icu-project.org/trac/ticket/11370 http://bugs.icu-project.org/trac/ticket/11371 13. Apply the patch for collator - patches/col.patch - No upstream bug filed because the upstream code was completely rewritten during the ICU 53 cycle.
