largefiles: reuse "findcommonoutgoing()" result at "hg push" Before this patch, "hg push" invokes "findcommonoutgoing()" not only in "exchange.push()" but also in "lfilesrepo.push()", when largefiles is enabled. The latter is redundant. This patch registers own "prepushoutgoinghook" function into "prepushoutgoinghooks" of "localrepository" to reuse "findcommonoutgoing()" result. "prepushoutgoinghook" omits "changelog.nodesbetween()" invocation, because "findcommonoutgoing()" invocation in "exchange.push()" takes "onlyheads" argument and it considers "nodesbetween()".

localrepo: introduce "prepushoutgoinghooks" to extend outgoing check easily This patch introduces "prepushoutgoinghooks" to extend outgoing check before pushing changesets to remote easily. This chooses the function returning "util.hooks" instead of the one to be overridden. The latter may cause problems silently, if one of overriders forgets (or fails) to execute a kind of "super(xxx, self).overridden(...)". In the other hand, the former can ensure that all registered functions are invoked, unless one of them raises an exception.

largefiles: centralize the logic to get outgoing largefiles Before this patch, "overrides.getoutgoinglfiles()" (called by "overrideoutgoing()" and "overridesummary()") and "lfilesrepo.push()" implement similar logic to get outgoing largefiles separately. This patch centralizes the logic to get outgoing largefiles in "lfutil.getlfilestoupload()". "lfutil.getlfilestoupload()" takes "addfunc" argument, because each callers need different information (and it is useful for enhancement in the future). - "overrides.getoutgoinglfiles()" needs only filenames - "lfilesrepo.push()" needs only hashes of largefiles

cat: support cat with explicit paths in subrepos The cat command with an explicit path into a subrepo is now handled by invoking cat on the file, from that subrepo. The previous behavior was to complain that the file didn't exist in the revision (of the top most repo). Now when the file is actually missing, the revision of the subrepo is named instead (though it is probably desirable to continue naming the top level repo). The documented output formatters %d and %p reflect the path from the top level repo, since the purpose of this is to give the illusion of a unified repository. Support for the undocumented (for cat) formatters %H, %R, %h, %m and %r was added long ago (I tested back as far as 0.5), but unfortunately these will reflect the subrepo node instead of the parent context. The previous implementation was a bit loose with the return value, i.e. it would return 0 if _any_ file requested was cat'd successfully. This maintains that behavior.

cat: move most of the implementation into cmdutils.cat() This will allow access to the reusable parts from subrepos, similar to add(), forget(), etc.

color: add effect to the template symbol table Previously, words like 'red' had to be protected by quotes before passing to the label template function. Now, we add color effects to the symbol table so that commands like, $ hg log -r . -T "{label(red, node|short)}\n" can work without the need for quoting.

amend: invoke editor forcibly when "--edit" option is specified 422981492ace introduces "--edit" option into "hg commit", but it doesn't work for "hg commit --amend", because 422981492ace prepares for editor invocation only around "commitfunc()" internal function, which is used only for temporary amend commit by "cmdutil.amend()". Actual commit message editing is executed in "cmdutil.amend()". This patch invokes editor forcibly when "--edit" option is specified for "hg commit --amend", even if commit message is specified explicitly by "--message" or "--logfile". This patch also removes useless handling for commit message and editor invocation around "commitfunc()" internal function.

commit: abolish useless "--force-editor" internal option for "hg commit" "--force-editor" option for "hg commit" has been useless since 12721a20ed30, which makes "commands.tag()" invoke "cmdutil.commit()" directly instead of "commands.commit()" with "--force-editor" internal option. This patch abolishes useless "--force-editor" internal option for "hg commit".
