| |
| 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 Jan 9, 2015, the latest version is 2014j and the above files |
| are available at |
| http://source.icu-project.org/repos/icu/data/trunk/tzdata/icunew/2014j/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 |
| |

| 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 was filed because the upstream code was completely |
| rewritten during the ICU 53 cycle. |
| |
| 14. Fix a bug in locid (getBaseName is wrong). |
