manifest: make one use of _mancache avoid manifestctxs 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. This fixes one case of it that can be fixed by using the other cache. Future patches will address the others uses using the upcoming manifestctx.read() function.

debugrevspec: add option to verify optimized result This provides a convenient way to diff "hg debugrevspec" outputs generated with/without --no-optimized option.

debugrevspec: add option to skip optimize() and evaluate unoptimized tree This will help debugging optimizer bugs. Maybe '--no-optimized' can be changed to '--optimized' (default: True) when flags series landed.

revset: remove showwarning option from expandaliases() Now all callers pass showwarning=ui.warn, so we no longer need the option to suppress warnings.

debugrevspec: evaluate tree built by itself Prepares for new option to evaluate an unoptimized tree. Since a revset expression is no longer parsed twice, alias warnings should be displayed at the first parsing stages. That's why showwarning=ui.warn is added.

localrepo: make _refreshfilecachestats unfiltered method to refresh correctly Before this patch, if transaction is started via "filtered repo" object, _refreshfilecachestats() at closing transaction doesn't refresh file stat of any @filecache properties correctly, because: - _refreshfilecachestats() omits refreshing file stat of a @filecache property, if it doesn't appear in self.__dict__ - if transaction is started via "filtered repo", _refreshfilecachestats() is applied on "filtered repo" because repo.transaction() adds "self._refreshfilecachestats" to post close procedures. repo.transaction() isn't unfiltered method, and "self" in it means "filtered repo" in this case. Transactions started by explicit repo.transaction() easily causes this situation. - _refreshfilecachestats() applied on "filtered repo" omits whole refreshing because @filecache properties are stored into "unfiltered repo", and appear only in self.__dict__ of "unfiltered repo". This incorrect refreshing causes unnecessary reloading from files. To refresh file stat of @filecache properties at closing transaction correctly, this patch makes _refreshfilecachestats() unfiltered method. This patch chooses making _refreshfilecachestats() unfiltered method instead of making transaction() unfiltered method, to reduce unexpected side effect.

streamclone: clear caches after writing changes into files for visibility Before this patch, streamclone-ed changes are invisible via @filecache properties to in-process procedures before closing transaction (e.g. pretxnclose python hook), if corresponded property is cached before consumev1(). Strictly speaking, caching should occur inside (store) lock for transaction. repo.invalidate() after closing transaction is too late to force @filecache properties to be reloaded from changed files at next access. For visibility of streamclone-ed changes to in-process procedures before closing transaction, this patch clears caches just after writing changes into files. BTW, regardless of changing in this patch, clearing cached properties in consumev1() causes inconsistency, if (1) transaction is started and (2) any @filecache property is changed before consumev1(). This patch also adds the comment to fix this (potential) inconsistency in the future.
