Richard Purdie 564c687c2a bitbake: parse/ConfHander/BBHandler/utils: Fix cache dependency bugs
Currently bitbake only adds files to its dependency list if they exist.
If you add 'include foo.inc' to your recipe and the file doesn't exist,
then later you add the file, the cache will not be invalidated.

This leads to another bug which is that if files don't exist and then
you add them and they should be found first due to BBPATH, again the
cache won't invalidate.

This patch adds in tracking of files we check for the existence of so
that if they are added later, the cache correctly invalidates. This
necessitated a new version of bb.utils.which which returns a list of
files tested for.

The patch also adds in checks for duplicate file includes and for now
prints a warning about this. That will likely become a fatal error at
some point since its never usually desired to include a file twice.

The same issue is also fixed for class inheritance. Now when a class
is added which would be found in the usual search path, it will cause
the cache to be invalidated.

Unfortunately this is old code in bitbake and the patch isn't the
neatest since we have to work within that framework.

Martin Jansa aa0b237144 bitbake: parse: Return IOError when including file with absolute path
* resolve_file was behaving different when relative and absolute
  paths were passed to it

* include relative-path/non-existent-file.inc
  works correctly resolve_file throws IOError, BBHandler.py:handle()
  doesn't catch it, ConfHandler.py:include() catches IOError and shows:
  DEBUG: CONF file 'relative-path/non-existent-file.inc' not found
* include /absolute-path/non-existent-file.inc
  was failing, because resolve_file just returns fn,
  BBHandler.py:handle() calls bb.parse.mark_dependency(d, abs_fn)
  which throws:
  OSError: [Errno 2] No such file or directory: '/absolute-path/non-existent-file.inc'
  and parsing fails.
  Ad isfile() test for absolute fn and throw IOError to make
  resolve_file behavior consistent for both paths.

* I know we had some issues with -b relative-path-to-recipe.bb and
  absolute path, so consider this patch only as RFC and documentation of
  this problem

* Catch OSError too in ConfHandler.py:include() e.g. in case the file exists, but user
  cannot read it or something like that.

Richard Purdie 8bef99d3c8 bitbake: methodpool: Retire it, remove global method scope
Having a global method scope confuses users and with the introduction
of parallel parsing, its not even possible to correctly detect conflicting
functions. Rather than try and fix that, its simpler to retire the global
method scope and restrict functions to those locations they're defined
within. This is more what users actually expect too.

If we remove the global function scope, the need for methodpool is reduced
to the point we may as well retire it. There is some small loss of caching
of parsed functions but timing measurements so the impact to be neglibile
in the overall parsing time.

Richard Purdie 83e1015684 bitbake: ConfHandler: Improve regexp to fix mis-parsing of += and no whitespace
If you have:

FOO = "a"
FOO += "b"
FOO+= "c"

The expected result is "a b c" however we were seeing "a b" with the FOO+
variable being assigned the value "c". This isn't the expected result.

We need to make the name part of the variale non-greedy so that any + character
becomes part of the operator. This patch does that. I compared the configuration
in OE-Core before and after the change and only the test case changed.

Richard Purdie 73dc22b728 bitbake: bitbake: BBHandler/ConfHandler: Improve multiline comment handling
Faced with an expression like:

 # Some comment \
 FOO = "bar"

what should bitbake do? Technically, the \ character means its multiline and
currently the code treats this as a continuation of the comment. This can
surprise some people and is not intuitive.

This patch makes bitbake simply error and asks the user to be clearer
about what they mean.

Richard Purdie 8ead7dc3cc bitbake: BBHandler/ast: Simplify/fix EXPORT_FUNCTIONS usage
The current usage of EXPORT_FUNCTIONS is rather problematic since a class
list (classes) is passed into the ast statement and cached as it was
when first parsed. This class list may be different in other cases but
is locked once in the cache.

Worse, the construction of classes can be broken by exceptions during parsing
at the wrong moments since the state of the parser is not always reset
correctly. This can lead to leakage of other classes into the classes list.

The current EXPORT_FUNCTIONS implementation looks at the last two currently
inherited classes and sets up an indirect function call view the second last
class inherited, e.g.:

 do_configure calls gnomebase_do_configure
 gnomebase_do_configure calls autotools_do_configure

This intermediary doesn't seem to serve a useful purpose.

This patch therefore makes builds deterministic and fixes various cache problems
and indirection by removing the intermediaries and simply performing
directly mapping for the cases where its needed.

Richard Purdie b85c30bb7d bitbake: parse/ConfHandler: Add negative lookahead to spot some quoting problems
Syntax like:

FOO = "bar" # eek"

would result in FOO taking the value 'bar" #eek' which is clearly
not the intention. Whilst our metadata is riddled with mixtures of even
quotes like:

FOO = "d.getVar("X")"

odd numbers of quotes seem rare. This patch adds detection of one odd
quote which we don't have any of in OE-Core so it seems a valid sanity
improvement.

The export regexp was only meant to catch values like:

however after the stricter quoting patch was applied, it was also matching
variables like:

export BAR=foo

is an invalid variable name character. This patch tightens up the regexp
match so it only matches the intended character set and only matches variable
names.

Richard Purdie f60a5d159b bitbake/ConfHandler: Be more strict about variable quoting
Currently, bitbake will accept variables in the forms:

X = 1
X = '1 \

X = "1"
X = '1'

which will all set X=1. This patch removes the first two possibilities
and makes quoting mandatory. There is little metadata out there which
doesn't quote properly and bitbake will exit with an error about the
exact line number and file with any problem so users can easily identify
and fix issues. OE-Core has already been checked/fixed.

The motivation for this is being able to give sane errors if a user
does something like:

IMAGE_INSTALL += # tslib mtd-utils"

which currently gives a really nasty failure.

When parsing multiline variables in conf files, the last character can
be accidentally removed. s2 contains new data read from the file which
may or may not end with the continuation character. It makes sense to
let the next loop iteration strip this if needed.

We don't often use multiline expressions in .conf files which is why I'd
imagine we haven't noticed this before. Most variables are quoted and
its the closing quotation which often disappears.

Chris Larson c244243274 Implement BBVERSIONS
This implements a feature similar to BBCLASSEXTEND, but for generating
multiple versions of a given recipe.  For example: BBVERSIONS = "1.0 2.0 git".

In addition to the above, one can utilize [a-b] style patterns, and can have a
:<basever> postfix, which allows you to essentially name the range of
versions.  Both the current version and the basever end up in OVERRIDES, and
the basever gets placed into the BPV variable.  The default BPV, if none is
specified, is the original PV of the recipe, before bbversions processing.

In this way, you can do things like:
BBVERSIONS = "1.0.[0-6]:1.0.0+
              1.0.[7-9]:1.0.7+"

SRC_URI_append_1.0.7+ = "file://some_extra_patch.patch;patch=1"

Or you can create a recipe per range, and name the recipe file as such: nano_1.0.7+.bb.
