The export symbol regular expression processing is updated to make
several improvements:
* The export expression (export_symbols_regex) now applies to both
functions and global variables
* A named capture group is used to match symbols. This allows the
export expression to contain capture groups without disrupting the
expression matching
E.g. when running 'waf xcode6 --targets=some-target'
File "/waf/waflib/Scripting.py", line 167, in waf_entry_point
run_commands()
File "/waf/waflib/Scripting.py", line 268, in run_commands
ctx = run_command(cmd_name)
File "/waf/waflib/Scripting.py", line 252, in run_command
ctx.execute()
File "/waf/waflib/extras/xcode6.py", line 679, in execute
self.post_group()
File "/waf/waflib/Build.py", line 767, in post_group
if self.current_group < self._min_grp:
AttributeError: 'xcode' object has no attribute '_min_grp'
Build flags like 'cflags', 'cxxflags' passed to xcode6 builds
are now considered by the xcode6 tool. For example, running command 'waf xcode6'
with the following wscript:
cnf.env.CXXFLAGS = ['-std=c++11']
...
bld.program(..., cxxflags='-O3')
now sets the OTHER_CPLUSCPLUSFLAGS in Xcode to '-O3 -std=c++11'
The tool was using an relative path for the includes, but an absolute
for the src-files. Protoc cannot distinguish between relative and
absolute paths and is not able to find sources when relative and
absolute paths are combined.
Tested with protoc 2.6.1, python 3.5.1
* Let default uselib_store and define_name be upper case of the first
word of package. This is a better default when package includes a
version specified.
* Remove undocumented *k argument extraction from check_cfg since it
breaks when the first argument includes a version specifier.
* Validate msg in only on block.
* Reduce the number of places that set okmsg.
* Require exactly one action to be requested.
* Also print the detected version on successful modversion.
Because Python's set type is unordered, storing include paths in it
can produce unnecessary re-builds by generating different compiler
command lines between successive builds. Avoid this by using the
sorted() function on the includes.
The documentation for Python ≥ 2.7 guarantees that sorted() is stable,
while for Python 2.5–2.6 it uses the same algorithm as list.sort(),
which is stable [1].

It appears that quite a few builds use the swig tool technique
of setting build dependencies after the build starts. Missing
entries in Runner/revdeps can make builds non-terminating.
- Have Task.weight apply to the current task only
- Do not rely on object addresses to set the build order
- Introduce tg.tg_idx_count to count task generators
- Enable propagating/non-propagating weights through Task.tree_weight/Task.weight
