manifest: backed out changeset b60a5fe98b73 There is some suspicious failure in evolution tests. This changeset was supposed to be dropped until we investigate.

debugrevspec: deprecate --optimize option This option has been superseded by '--show-stage NAME', and will cause confusion in future patches.

debugrevspec: add option to print parsed tree at given stages "-p <stage>" is useful for investigating parsing stages. With -p option, a transformed tree is printed no matter if it is changed or not, which allows us to know valid stage names by "-p all".

debugrevspec: transform and print parsed tree by stages Prepares for adding new option to print transformed tree at each stage.

debugrevspec: build parsed tree even if no --verbose specified Prepares for evaluating unoptimized tree. The output is suppressed by ui.note() anyway.

osutil: fix the declaration to work on different sizes of off_t

manifest: change manifestctx to not inherit from manifestdict If manifestctx inherits from manifestdict, it requires some weird logic to lazily load the dict if a piece of information is asked for. This ended up being complicated and unintuitive to use. Let's move the dict creation to .read(). This will make even more sense once we start adding readdelta() and other similar methods to manifestctx.

manifest: make uses of _mancache aware of contexts In a future patch we will change manifestctx and treemanifestctx to no longer derive from manifestdict and treemanifest, respectively. This means that consumers of the _mancache will now need to be aware of the different between the two, until we get rid of the manifest entirely and the _mancache becomes only filled with ctxs.

manifest: add treemanifestctx class Before we start using repo.manifestlog in the rest of the code base, we need to make sure that it's capable of returning treemanifests. As we add new functionality to manifestctx, we'll add it to treemanifestctx at the same time. We also comment out the manifestctx p1, p2, and linkrev fields for now, since we're not implementing them on treemanifest yet.

revset: add public function to create matcher from evaluatable tree "hg debugrevspec" will use it to evaluate unoptimized tree.
