templater: remove __iter__() from _hybrid, resolve it explicitly The goal is to fix "{hybrid_obj|json}" output. A _hybrid object must act as a list or a dict as well as a generator of legacy template strings. Before, _hybrid.__iter__() was assigned for legacy template, which conflicted with list.__iter__() API. This patch drops _hybrid.__iter__() and makes stringify/flatten functions unwrap a generator instead.

templater: rewrite doc of _hybrid class as docstring

sortdict: fix .pop() to return a value My future patch will need it.

checkcode: only match pushd/popd as word otherwise it partially match common words like "pushdestination".

treemanifest: add walksubtrees api Adds a new function to treemanifest that allows walking over the directories in the tree. Currently it only accepts a matcher to prune the walk, but in the future it will also accept a list of trees and will only walk over subtrees that differ from the versions in the list. This will be useful for identifying what parts of the tree are new to this revision, which is useful when deciding the minimal set of trees to send to a client given that they have a certain tree already. Since this is intended for an extension to use, the only current consumer is a test. In the future this function may be useful for implementing other algorithms like diff and changegroup generation.

upgrade: extract code in its own module Given about 2/3 or 'mercurial.repair' is now about repository upgrade, I think it is fair to move it into its own module. An expected benefit is the ability to drop the 'upgrade' prefix of many functions. This will be done in coming changesets.

bundle2: move the 'close' method off the unpackermixin This method is unrelated to unpacking and only used by the unbundle20 class. We move it there for clarity.

bundle2: clarify the docstring of unpackermixin methods The unpackermixin is a utility used to implement the bundle2 protocol. It should not be used when writing part handlers. We update the docstring to clarify this.

bundle2: add documention to 'part.addparams' There are some non-obvious limitations on the parameters of this method. Add some documentation where people will likely look to understand how to use this API.

test-patchbomb: disable sendmail tests on Windows These tests were failing, and there isn't a trivial way to execute a script on Windows [1]. [1] https://www.mercurial-scm.org/pipermail/mercurial-devel/2017-April/096497.html

show: fix corrupt json output with no bookmarks

show: tweak plain abort language for clarity

tests: print Unix style paths in *.py tests These tests don't support (glob). I didn't audit all tests, but these ones were failing.

revlog: make "size" diverge from "rawsize" Previously, revlog.size equals to revlog.rawsize. However, the flag processor framework could make a difference - "size" could mean the length of len(revision(raw=False)), while "rawsize" means len(revision(raw=True)). This patch makes it so. This corrects "hg status" output when flag processor is involved. The call stack looks like: basectx.status -> workingctx._buildstatus -> workingctx._dirstatestatus -> workingctx._checklookup -> filectx.cmp -> filelog.cmp -> filelog.size -> revlog.size

test-flagprocessor: add a case about hg status This shows how "hg status" is wrong - nothing changed but the file is labeled as "M".

test-http-proxy: add the Windows variant of "connection refused" The full error is "No connection could be made because the target machine actively refused it".

test-fileset: eliminate a duplicate test that was conditionalized for output

test-fileset: glob away hash differences There are various files committed above that can't be used on Windows because of the name, or being a symlink.

test-bundle: glob away a URL protocol separator MSYS thinks the ':' is a Unix path separator, and replaces it with ';'.

templatekw: clarify the result of {latesttag} when no tag exists My initial expectation was that the list would be empty, and therefore detectable with {if()}. The map for {latesttag()} is populated with real values in this case (except {tag}), so it probably doesn't make any sense to change this to an empty list.

hgweb: position the "followlines" box close to latest cursor position
