2013-01-21xc-cc-check.m4: re-evaluate exporting and AC_SUBST'ing varsYang Tse
Notes: When running a configure script that has nested packages (for example libcurl's configure with --enable-ares and c-ares sources embedded in curl tree) and AC_CONFIG_SUBDIRS([nested-subdir]) machinery is used to automatically run the nested configure script from within the parent configure script, it happens that the nested _shell_ script will inherit shell variables exported from the parent _shell_ script. If for example parent configure script sets and exports LDFLAGS and LIBS variables with proper values in order to link either a parent library or program with a library which will be configured and built by a nested package; It will happen that when the nested configure script runs, the nested library does not exist yet and _any_ link-test done in the nested configure will fail, such as those that autoconf macros perform in order to detect existing compiler and its characteristics, the result is that the nested configure script will fail with errors such as: configure: error: C compiler cannot create executables For now, we no longer export variables previously exported here. On the other hand, AC_SUBST'ing them is appropriate and even with nested packages each package's config.status gets its own package values. So we reinstate AC_SUBST'ing previously AC_SUBST'ed variables.

2013-01-20configure: autotools compatibility fixes - step IYang Tse
Fix proper macro expansion order across autotools versions for C compiler and preprocessor program checks.
2013-01-14configure: fix automake 1.13 compatibilityYang Tse
Tested with: buildconf: autoconf version 2.69 buildconf: autom4te version 2.69 buildconf: autoheader version 2.69 buildconf: automake version 1.13.1 buildconf: aclocal version 1.13.1 buildconf: libtool version 2.4 buildconf: GNU m4 version 1.4.16
2013-01-09build: fix circular header inclusion with other packagesYang Tse
This commit renames lib/setup.h to lib/curl_setup.h and renames lib/setup_once.h to lib/curl_setup_once.h. Removes the need and usage of a header inclusion guard foreign to libcurl. [1] Removes the need and presence of an alarming notice we carried in old setup_once.h [2] ---------------------------------------- 1 - lib/setup_once.h used __SETUP_ONCE_H macro as header inclusion guard up to commit ec691ca3 which changed this to HEADER_CURL_SETUP_ONCE_H, this single inclusion guard is enough to ensure that inclusion of lib/setup_once.h done from lib/setup.h is only done once. Additionally lib/setup.h has always used __SETUP_ONCE_H macro to protect inclusion of setup_once.h even after commit ec691ca3, this was to avoid a circular header inclusion triggered when building a c-ares enabled version with c-ares sources available which also has a setup_once.h header. Commit ec691ca3 exposes the real nature of __SETUP_ONCE_H usage in lib/setup.h, it is a header inclusion guard foreign to libcurl belonging to c-ares's setup_once.h The renaming this commit does, fixes the circular header inclusion, and as such removes the need and usage of a header inclusion guard foreign to libcurl. Macro __SETUP_ONCE_H no longer used in libcurl. 2 - Due to the circular interdependency of old lib/setup_once.h and the c-ares setup_once.h header, old file lib/setup_once.h has carried back from 2006 up to now days an alarming and prominent notice about the need of keeping libcurl's and c-ares's setup_once.h in sync. Given that this commit fixes the circular interdependency, the need and presence of mentioned notice is removed. All mentioned interdependencies come back from now old days when the c-ares project lived inside a curl subdirectory. This commit removes last traces of such fact.

2013-01-01curl-override.m4: provide AC_CONFIG_MACRO_DIR definition conditionallyYang Tse
Provide a 'traceable' AC_CONFIG_MACRO_DIR definition only when using an autoconf version that does not provide it, instead of what we were doing up to now of providing and overriding AC_CONFIG_MACRO_DIR for all autoconf versions.
2012-12-28build: make use of 76 lib/*.h renamed filesYang Tse
76 private header files renamed to use our standard naming scheme. This change affects 322 files in libcurl's source tree.

2012-11-16autoconf: don't force-disable compiler debug optionDaniel Stenberg
When nothing is told to configure, we should not enforce switching off debug options with -g0 (or similar). We instead don't use -g at all in that situaion and therefore allow the user's CFLAGS settings possibly dictate what to do.
2012-08-16configure: remove the --enable/disable-nonblocking optionsDaniel Stenberg
Removing this option as it currently only functions to lure people into wrongly using it and falsely believing that libcurl will work fine without using nonblocking sockets internally - which leads to hard to track or understand errors.
2012-06-29curl-compilers.m4: remove -Wstrict-aliasing=3 from clangYang Tse
Currently it is unknown if there is any version of clang that actually supports -Wstrict-aliasing. What is known is that there are several that don't support it.
2012-06-26curl-compilers.m4: -Wstrict-aliasing=3 for warning enabled gcc and clang buildsYang Tse

2012-04-16curl-compilers.m4: -Wno-pedantic-ms-format for Windows gcc 4.5 buildsYang Tse
When building a Windows target with gcc 4.5 or newer and strict compiler warnings enabled use -Wno-pedantic-ms-format in addition to other flags.
2012-04-14headers: surround GCC attribute names with double underscoresJonathan Nieder
This protects from attribute names being defined by third party's code. Improvement: http://curl.haxx.se/mail/lib-2012-04/0127.html
2012-04-11build adjustments: CURL_HIDDEN_SYMBOLS no longer defined in config filesYang Tse
configure script now provides conditional definitions for Makefile.am that result in CURL_HIDDEN_SYMBOLS being defined by resulting makefiles when appropriate. Additionally, configure script option for symbol hiding control is now named --enable-symbol-hiding --disable-symbol-hiding. While still valid, old option name --enable-hidden-symbols --disable-hidden-symbols will be deprecated in some future release.
2012-03-28curl-functions.m4: update detection logic of getaddrinfo() thread-safenessYang Tse
Take in account that h_errno might be a modifiable lvalue not defined as a C preprocessor macro
2012-03-21curl-functions.m4: update detection logic of getaddrinfo() thread-safenessYang Tse
Take in account that POSIX standard Issue 7 drops h_errno support. Now, we also consider getaddrinfo() to be thread-safe when (_POSIX_C_SOURCE >= 200809L) or (_XOPEN_SOURCE >= 700) independently of whether h_errno exists or not.

2011-09-28configure openssl version check: handle lack of L suffixDaniel Stenberg
It seems some versions of the OpenSSL version defines don't come with L appended to the number, so let's deal with that nicely.
2011-08-27NTLM_WB: final congruency naming adjustmentsYang Tse
Configure script option --enable-wb-ntlm-auth renamed to --enable-ntlm-wb Configure script option --disable-wb-ntlm-auth renamed to --disable-ntlm-wb Preprocessor symbol WINBIND_NTLM_AUTH_ENABLED renamed to NTLM_WB_ENABLED Preprocessor symbol WINBIND_NTLM_AUTH_FILE renamed to NTLM_WB_FILE Test harness env var CURL_NTLM_AUTH renamed to CURL_NTLM_WB_FILE Static function wb_ntlm_close renamed to ntlm_wb_cleanup Static function wb_ntlm_initiate renamed to ntlm_wb_init Static function wb_ntlm_response renamed to ntlm_wb_response
2011-08-27NTLM single-sign on adjustments (XI)Yang Tse
Feature string literal NTLM_SSO renamed to NTLM_WB. Preprocessor symbol USE_NTLM_SSO renamed to WINBIND_NTLM_AUTH_ENABLED. curl's 'long' option 'ntlm-sso' renamed to 'ntlm-wb'. Fix some comments to make clear that this is actually a NTLM delegation.
2011-08-08curl-compilers.m4: serial number bumpYang Tse
2011-08-08curl-compilers.m4: CURL_CONVERT_INCLUDE_TO_ISYSTEM adjustments:Yang Tse
Add CURL_CHECK_COMPILER as a requirement. Ensure macro does nothing unless GNU_C or CLANG compiler is used. This should allow usage of this macro in unforeseen placements.
2011-07-31NTLM single-sign on adjustments (VIII)Yang Tse
Use preprocessor symbols WINBIND_NTLM_AUTH_ENABLED and WINBIND_NTLM_AUTH_FILE for Samba's winbind daemon ntlm_auth helper code implementation and filename. Retain preprocessor symbol USE_NTLM_SSO for NTLM single-sign-on feature availability implementation independent. For test harness, prefix NTLM_AUTH environment vars with CURL_ Refactor and rename configure option --with-ntlm-auth to --enable-wb-ntlm-auth[=FILE]

2010-11-10curl-functions: provide xattr function tests that also check number of argumentsYang Tse
2010-11-10write extended attributes by using fsetxattrStefan Tomanek
Instead of reopening the downloaded file, fsetxattr uses the (already open) file descriptor to attach extended attributes. This makes the procedure more robust against errors caused by moved or deleted files.
