* devtool: implement conditional patch handlingPaul Eggleton2017-11-111-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you have a recipe that uses overrides to conditionally extend SRC_URI to add additional patches, then you will often need to update those patches if you're making other changes to the source tree (for example if you're upgrading the underlying source). Make this possible with devtool by creating devtool-override-* branches for each override that conditionally appends/prepends SRC_URI, and have devtool update-recipe / finish check each branch out in turn and update the corresponding patches. A current example of a recipe that does this is the quota recipe - it applies an additional patch if musl is the selected C library (i.e. libc-musl is in OVERRIDES). Note that use of this functionality does require some care - in particular, updates to patches that appear on the main branch (named "devtool" by default) should be made there and not only on one of the specific devtool-override-* branches that are created for each override. The recommended procedure is to make the changes you want to make to the main branch first, then check out and rebase each devtool-override-* branch, testing each one by activating the corresponding configuration, and then finally run devtool finish.

* devtool: rework source extraction so that dependencies are handledPaul Eggleton2017-09-181-0/+165
Since it was first implemented, devtool's source extraction (as used by the devtool modify, extract and upgrade subcommands) ignored other recipe dependencies - so for example if you ran devtool modify on a recipe that fetches from svn or is compressed using xz then it would fail if those dependencies hadn't been built first. Now that we can execute tasks in the normal way (i.e. tinfoil.build_targets()) then we can rework it to use that. This is slightly tricky in that the source extraction needs to insert some logic in between tasks; luckily we can use a helper class that conditionally adds prefuncs to make that possible. Some side-effects / aspects of this change worth noting: * Operations are a little slower because we have to go through the task dependency graph generation and other startup processing. There's not really any way to avoid this though. * devtool extract didn't used to require a workspace, now it does because it needs to create a temporary bbappend for the recipe. (As with other commands the workspace be created on the fly if it doesn't already exist.) * I want any existing sysroot files and stamps to be left alone during extraction since we are running the tasks off to the side, and especially devtool extract should be able to be used without touching these. However, this was hampered by the automatic removal process in sstate.bbclass triggered by bb.event.ReachableStamps when the task signatures change, thus I had to introduce a way to disable this removal on a per-recipe basis (we still want it to function for any dependencies that we aren't working on). To implement this I elected to use a file written to tmp/sstate-control which gets deleted automatically after reading so that there's less chance of stale files affecting future sessions. I could have used a variable but this would have needed to be whitelisted and I'd have to have poked its value in using the setVariable command. Fixes [YOCTO #11198].
