From 95ee619df135a4c8b3ecefe65503c6d1cc7c36da Mon Sep 17 00:00:00 2001 From: Paul Joseph Davis Date: Thu, 26 Nov 2009 19:31:00 +0000 Subject: Complete refactoring of couch_js. In particular, the cURL bindings have been rewritten to be more useful and easily applied in command line scripts. git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@884672 13f79535-47bb-0310-9956-ffa450edef68 --- .gitignore | 5 + bin/Makefile.am | 2 +- etc/couchdb/Makefile.am | 2 +- src/couchdb/priv/Makefile.am | 32 +- src/couchdb/priv/couch_js/couch_js.c | 1286 -------------------------------- src/couchdb/priv/couch_js/curlhelper.c | 255 ------- src/couchdb/priv/couch_js/curlhelper.h | 49 -- src/couchdb/priv/couch_js/http.c | 647 ++++++++++++++++ src/couchdb/priv/couch_js/http.h | 18 + src/couchdb/priv/couch_js/main.c | 324 ++++++++ src/couchdb/priv/couch_js/utf8.c | 286 +++++++ src/couchdb/priv/couch_js/utf8.h | 19 + test/etap/Makefile.am | 2 +- 13 files changed, 1333 insertions(+), 1594 deletions(-) delete mode 100644 src/couchdb/priv/couch_js/couch_js.c delete mode 100644 src/couchdb/priv/couch_js/curlhelper.c delete mode 100644 src/couchdb/priv/couch_js/curlhelper.h create mode 100644 src/couchdb/priv/couch_js/http.c create mode 100644 src/couchdb/priv/couch_js/http.h create mode 100644 src/couchdb/priv/couch_js/main.c create mode 100644 src/couchdb/priv/couch_js/utf8.c create mode 100644 src/couchdb/priv/couch_js/utf8.h diff --git a/.gitignore b/.gitignore index 69e07e9a..be37e00a 100644 --- a/.gitignore +++ b/.gitignore @@ -58,7 +58,12 @@ src/couchdb/priv/.libs/ src/couchdb/priv/couch_icu_driver.la src/couchdb/priv/couchjs src/couchdb/priv/couchspawnkillable +src/couchdb/priv/stat_descriptions.cfg +src/erlang-oauth/oauth.app +src/ibrowse/ibrowse.app +src/mochiweb/mochiweb.app test/local.ini +test/etap/run test/etap/test_util.erl share/server/main.js diff --git a/bin/Makefile.am b/bin/Makefile.am index fc84b1a8..b8b818cb 100644 --- a/bin/Makefile.am +++ b/bin/Makefile.am @@ -60,7 +60,7 @@ couchjs: couchjs.tpl chmod +x $@ couchjs_dev: couchjs.tpl - sed -e "s|%locallibbindir%|$(abs_top_builddir)/src/couchdb|g" \ + sed -e "s|%locallibbindir%|$(abs_top_builddir)/src/couchdb/priv|g" \ -e "s|%bug_uri%|@bug_uri@|g" \ -e "s|%package_author_address%|@package_author_address@|g" \ -e "s|%package_author_name%|@package_author_name@|g" \ diff --git a/etc/couchdb/Makefile.am b/etc/couchdb/Makefile.am index b5d8aaf0..ded52084 100644 --- a/etc/couchdb/Makefile.am +++ b/etc/couchdb/Makefile.am @@ -11,7 +11,7 @@ ## the License. couchprivlibdir = $(localerlanglibdir)/couch-$(version)/priv/lib -devcouchprivlibdir = $(abs_top_builddir)/src/couchdb/.libs +devcouchprivlibdir = $(abs_top_builddir)/src/couchdb/priv/.libs localconf_DATA = default.ini noinst_DATA = default_dev.ini local_dev.ini diff --git a/src/couchdb/priv/Makefile.am b/src/couchdb/priv/Makefile.am index d4c759c1..8c4383dc 100644 --- a/src/couchdb/priv/Makefile.am +++ b/src/couchdb/priv/Makefile.am @@ -15,11 +15,41 @@ couchprivdir = $(couchlibdir)/priv couchprivlibdir = $(couchlibdir)/priv/lib EXTRA_DIST = \ - couchspawnkillable.sh \ + spawnkillable/couchspawnkillable.sh \ stat_descriptions.cfg.in CLEANFILES = stat_descriptions.cfg +ICU_LOCAL_FLAGS = $(ICU_LOCAL_CFLAGS) $(ICU_LOCAL_LDFLAGS) +if WINDOWS +ICU_LOCAL_LIBS=-licuuc -licudt -licuin +else +ICU_LOCAL_LIBS=-licuuc -licudata -licui18n +endif + +couchprivlib_LTLIBRARIES = couch_icu_driver.la +couch_icu_driver_la_SOURCES = icu_driver/couch_icu_driver.c +couch_icu_driver_la_LDFLAGS = -module -avoid-version $(ICU_LOCAL_FLAGS) +couch_icu_driver_la_CFLAGS = $(ICU_LOCAL_FLAGS) +couch_icu_driver_la_LIBADD = $(ICU_LOCAL_LIBS) + +if WINDOWS +couch_icu_driver_la_LDFLAGS += -no-undefined +endif + +COUCHJS_SRCS = \ + couch_js/http.c \ + couch_js/http.h \ + couch_js/main.c \ + couch_js/utf8.c \ + couch_js/utf8.h + +locallibbin_PROGRAMS = couchjs +couchjs_SOURCES = $(COUCHJS_SRCS) +couchjs_LDFLAGS = $(CURL_LDFLAGS) +couchjs_CFLAGS = $(CURL_CFLAGS) +couchjs_LDADD = $(CURL_LDFLAGS) @JSLIB@ + couchpriv_DATA = stat_descriptions.cfg couchpriv_PROGRAMS = couchspawnkillable diff --git a/src/couchdb/priv/couch_js/couch_js.c b/src/couchdb/priv/couch_js/couch_js.c deleted file mode 100644 index 0acc5b55..00000000 --- a/src/couchdb/priv/couch_js/couch_js.c +++ /dev/null @@ -1,1286 +0,0 @@ -/* - -Licensed under the Apache License, Version 2.0 (the "License"); you may not use -this file except in compliance with the License.
