If you run bitbake-diffsigs against two differing sigdata files from
nostamp tasks it shows no difference despite the differing checksum.
Change the code so this shows up as a nostamp 'taint' and at least
makes the issue clearer to the end user.

Currently, if you reference a file url, its checksum is included in the
task hash, however if you change to a different file at a different
location, perhaps taking advantage of the FILESPATH functionality, the
system will not reparse the file in question and change its checksum to
match the new file.
To correctly handle this, the system not only needs to know if the
existing file still exists or not, but also check the existance
of every file it would have looked at when computing the original file.
We already do this in the bitbake parsing code for class inclusion. This
change uses the same technique to log the file list we looked at and
if files in these locations exist when they previously did not, to
invalidate and reparse the file.
Since data stored in the cache is flattened text, we have to use a string
form of the data and split on the ":" character which is ugly, but is
an internal detail we can improve later if a better method is found.
The cache version changes to trigger a reparse since the previous
cache data is now incompatible.

Similar to the last shared work task signature bug, we've found another
one. Looking at the improved output of diffsigs in this case:
runtaskdeps changed from [
'autoconf_2.69.bb.do_populate_sysroot:virtual:native',
'gnu-config_20120814.bb.do_populate_sysroot:virtual:native',
'libgcc-initial_4.9.bb.do_patch:virtual:nativesdk'
] to [
'autoconf_2.69.bb.do_populate_sysroot:virtual:native',
'gcc-crosssdk-initial_4.9.bb.do_patch',
'gnu-config_20120814.bb.do_populate_sysroot:virtual:native'
]
so we can get a different task hash since libgcc sorts before gnu-config
and gcc sorts after it. We could do with a way of fixing this, the best
I can come up with is to include a single parent directory. Since
recipes are never at the top of any metadata trees I've seen, this
should suffice for now.
I'm planning to burn the concept of shared work within bitbake
and do something at the metadata level in the 1.8 timeframe as its just
too fragile as things stand and hard to fix well.

With a shared work task like gcc, the task can be run from a variety of
different recipes which may have different virtual extensions in place.
Depending on whether gcc-runtime or nativesdk-gcc-runtime's do_preconfigure
task is called for example will change the sorting of the task hashes due
to the way clean_basename currently works.
The correct thing to do here is sort on the base filename first, then any
extension when ordering the hashes. This means we do account for things
like recipes with both a native and non-native dependency but we also fix
the shared work case where we don't care whether it was a virtual version
or not.

This fsync was added for belt and braces protection for things like sstate
on NFS. To be honest, it probably doesn't buy much, if the rename isn't
atomic, all bets are off anyway and there are bigger issues to worry about.
The issue is that at the end of every task, the dump_sig() code is triggered
to save out information about the task and this was triggering an fsync(fd).
Whilst it may select the file descriptor, on file systems like ext4, it will
require large parts of the journal to be written out so it can have
significant impact. latencytop showed an average fsync() call overhead of about
2s and if that happens for 5000 tasks, the time mounts up. This blocks the next
task execution by that time.
We therefore drop the fsync since in reality its causing problems and is unlikely
to buy much.

Currently the code prints all differences. If the task dependencies have changed hash,
we recurse into those and print those differences as well. This leads to a lot
of output. The reality is if the parents changed signature, we might as well just
say that and recurse with no other output since we're much more interested in how
the parents changed in nearly all cases. The changes in the parent are probably
the same ones we'd have printed at each level anyway.
By doing this we focus the output more carefully on the thing the user wants/needs

Avoid storing paths to files in SRC_URI when writing out the the
file checksums to siginfo files. This prevents a move of the source
directory being reported by bitbake-diffsigs as files being removed and
then added (the signature itself is not affected since the file paths
have never been included in the signature).
This has required the format of the file checksums in the siginfo file
to be changed from a dict to a list of tuples (in order to handle
multiple files with the same name under different paths, which is
uncommon but possible); the code remains backwards-compatible with older
siginfo files that use a dict however.

This is a pretty fundamental change to the way bitbake operates. It
splits out the task execution part of runqueue into a completely
separately exec'd process called bitbake-worker.
This means that the separate process has to build its own datastore and
that configuration needs to be passed from the cooker over to the
bitbake worker process.
Known issues:
* Hob is broken with this patch since it writes to the configuration
and that configuration isn't preserved in bitbake-worker.
* We create a worker for setscene, then a new worker for the main task
execution. This is wasteful but shouldn't be hard to fix.
* We probably send too much data over to bitbake-worker, need to
see if we can streamline it.
These are issues which will be followed up in subsequent patches.
This patch sets the groundwork for the removal of the double bitbake
execution for psuedo which will be in a follow on patch.

Though the value of variables in the BB_BASEHASH_WHITELIST is kept out of the
checksums, dependency on them is not, at least for variables and non-task
functions. In the code, the whitelist is removed from the overall task dep
list, but not the individual variable deps. The result of this is that
functions like sysroot_stage_all and oe_runmake end up with whitelisted
variables like TERM listed in their dependencies, which means that doing
a 'unset TERM' before building will result in all checksums for tasks that
depend on those changing, and shared state reuse not behaving correctly.
This is only really a potential issue for variables from the environment, as
it's the existance/removal of the variable that's an issue, not its value, and
the other whitelisted variables are set in our metadata. This which means in
practical terms the only cases where this is likely to be an issue are in
environments where one of the following are unset: TERM, LOGNAME, HOME, USER,
PWD, SHELL. This may seem like an unlikely circumstance, but is in fact a real
issue for those of us using autobuilders. Jenkins does not set TERM when
executing shell, which means shared state archives produced by your jenkins
server would not be fully reused by an actual user.
Fixed by removing the whitelisted elements from the individual variable deps,
not just the accumulated result.

Currently when we execute a task, we don't remove other potentially stale

This patch adds in functionality to allow a wildcard expression of stamp
files to be removed when creating a new stamp file. This patch adds in
the core of the code to enable this but it also requires metadata support
to enable it.
When writing this improvement I went through several different options but

If -f is specified, force dependent tasks to be re-run next time. This
works by changing the force behaviour so that instead of deleting the
task's stamp, we write a "taint" file into the stamps directory, which
will alter the taskhash randomly and thus trigger the task to re-run
next time we evaluate whether or not that should be done as well as
influencing the taskhashes of any dependent tasks so that they are
similarly re-triggered. As a bonus because we write this file as
<stamp file name>.taskname.taint, the existing code which deletes the
stamp files in OE's do_clean will already handle removing it.
This means you can now do the following:
bitbake somepackage
[ change the source code in the package's WORKDIR ]
bitbake -c compile -f somepackage
bitbake somepackage
and the result will be that all of the tasks that depend on do_compile
(do_install, do_package, etc.) will be re-run in the last step.
Note that to operate in the manner described above you need full hashing
enabled (i.e. BB_SIGNATURE_HANDLER must be set to a signature handler
that inherits from BasicHash). If this is not the case, -f will just
delete the stamp for the specified task as it did before.
This fix is required for [YOCTO #2615] and [YOCTO #2256].

Gathers a list of paths to have checksums calculated at parse time, and
processes these when calculating task hashes. Checksums are cached with
the file's current mtime. Thus, changing any local file in SRC_URI will
now cause the do_fetch taskhash to change, thus forcing a rebuild.
This change adds very roughly about an 8% increase in parse time (a few
seconds) and maybe a few seconds during runqueue generation, so a fairly
moderate performance hit.
Note that since paths are resolved at parse time, this will not force
a rebuild when files are introduced which would cause that resolved path
to be different - for example, where a machine-specific version of a file
was added without otherwise changing the recipe. This will need to be
handled in a future update.

* added test if there is different task with same hash then we don't
show it as added/removed dependency, because bitbake doesn't care

This means that custom signature handlers can override specific parts
of the code without having to reimplement whole functions allowing them
more flexibility.

The actual task names are discounted for comparison of dependent tasks, only
the actual hashes are used. This updates the comparison code to account for
this change, attempting heuristic matching for more user friendly output but
falling back to showing the changed hashes directly. This avoids some confusing
output to users where it looked like tasks had changed when they had not and
actually had the same hash but a different taskname.

Some BB_HASHBASE_WHITELIST variables are in the lists of variable
dependencies for signatures. Ignore those differences in lists
since this difference does not matter

This allows the code to safely fall back to dumping the basehash data
if the taskhash data isn't present for some reason. We could effecitvely
obsolete the runtime option and use this approach instead exclusively.

We have a problem if we want to inject specific information into the variable
dependency code. There are cases for example where we want a dependency
on the value of X but it doesn't matter how X was constructed or what
dependencies it might have had, we only care about the absolute value.
With the current code, its near enough impossible to do this.
This patch adds such a mechanism so the user can trigger this with code like:
baselib[vardepvalue] = "${baselib}"
It also refactors some of the code so we do variable lookups once
instead of doing this in two different functions.

Without this patch the tash hash dependencies can be in a order
that is dependent upon directory/filesystem layout. With this
change the data is sorted the same regardless.
Without this the dependent hashes could be in different orders
on different systems and consequently final md5 hash would differ
as well even though nothing else changed.
