ELinks 0.12pre4.GIT now:
|
||||
------------------------
|
||||
|
||||
To be released as 0.12pre5, 0.12rc1, or even 0.12.0. This branch also
|
||||
includes the changes listed under ``ELinks 0.11.6.GIT now'' below.
|
||||
|
||||
* bug 1080: Support ``--dump-color-mode'' with ``--dump-charset UTF-8''.
|
||||
* minor bug 1017: To work around HTTP server bugs, disable
|
||||
protocol.http.compression by default, until ELinks can report
|
||||
decompression errors or automatically retry the connection.
|
||||
|
||||
Bugs that should be removed from NEWS before the 0.12.0 release:
|
||||
|
||||
* critical bug 1081: To fix crashes caused by different definitions of
|
||||
regfree() in TRE and in the system libc, link with TRE before any
|
||||
other libraries. ELinks 0.12pre4 was the first release that had
|
||||
this bug.

# Bug 1081: If both TRE and libc define the regfree function,
|
||||
# ELinks needs to use the version defined by TRE because
|
||||
# that's the one compatible with regex_t initialized by the
|
||||
# regwcomp function of TRE. Therefore put $TRE_LIBS at the
|
||||
# very beginning of $LIBS so that the linker hopefully finds
|
||||
# regfree there before it examines libc. In particular,
|
||||
# $PERL_LIBS appears to often include "-lc".
|
||||
#
|
||||
# This scheme still risks a crash if ELinks is linked with
|
||||
# some static library that uses GNU <regex.h> extensions that
|
||||
# TRE does not implement. For example, the library might call
|
||||
# re_compile_pattern, which is found in GNU libc, and then
|
||||
# regfree, which is found in TRE and probably crashes with the
|
||||
# GNU-initialized regex_t. Ways to avoid such crashes:
|
||||
#
|
||||
# - Change TRE so it defines only tre_... functions and does
|
||||
# not attempt to override the POSIX names by default.
|
||||
#
|
||||
# - Change ELinks to access TRE only via dlopen and dlsym.
|
||||
# The problem then is how to find the correct file name.
|
||||
# There might be libtre.so.4 and libtre.so.5 with different
|
||||
# ABI. How can this configure script detect which of them
|
||||
# matches the <tre/regex.h> in the include path?
|
||||
#
|
||||
# - Replace the static library with a shared library. At
|
||||
# least on GNU/Linux, when the shared library is built, the
|
||||
# linker should note that e.g. regfree is defined in libc
|
||||
# and has the GLIBC_2.0 version there, and write that
|
||||
# version string to the shared library as well; because TRE
|
||||
# does not provide regfree with that version, any regfree
|
||||
# calls at run time should then get resolved to libc.
