util: add normcase spec and fallback These will be used in upcoming patches to efficiently create a dirstate foldmap.

hgk: display committer name when set by hg-git

jsonchangeset: set manifest node to "null" for workingctx Unlike changeset_printer, it does not hide the manifest field because JSON output will be parsed by machine where explicit "null" will be more useful than nothing.

jsonchangeset: set rev and node to "null" for workingctx

templater: tell hggettext to collect help of template functions

treemanifest: disable readdelta optimization When tree manifests are stored with one revlog per directory and loaded lazily, it's unclear how much readdelta will help. If only a few files change, then only a small part of the full manifest will be loaded, and the delta chains should also be shorter for tree manifests. Therefore, let's disable readdelta for tree manifests for now.

phases: make two functions private for phase computation

windows: define normcase spec and fallback These will be used in upcoming patches to efficiently create a dirstate foldmap.

encoding.upper: factor out fallback code This will be used as the fallback function on Windows.

cygwin: define normcase spec and fallback These will be used in upcoming patches to efficiently create a dirstate foldmap. The Cygwin normcase behavior is more complicated than just a simple lowercasing or uppercasing. That's why we specify 'other'.

darwin: define normcase spec and fallback These will be used in upcoming patches to efficiently create a dirstate foldmap.

posix: define normcase spec and fallback These will be used in upcoming patches to efficiently create a dirstate foldmap.

encoding: define an enum that specifies what normcase does to ASCII strings For C code we don't want to pay the cost of calling into a Python function for the common case of ASCII filenames. However, while on most POSIX platforms we normalize filenames by lowercasing them, on Windows we uppercase them. We define an enum here indicating the direction that filenames should be normalized as. Some platforms (notably Cygwin) have more complicated normalization behavior -- we add a case for that too. In upcoming patches we'll also define a fallback function that is called if the string has non-ASCII bytes. This enum will be replicated in the C code to make foldmaps. There's unfortunately no nice way to avoid that -- we can't have encoding import parsers because of import cycles. One way might be to have parsers import encoding, but accessing Python modules from C code is just awkward. The name 'normcasespecs' was chosen to indicate that this is merely an integer that specifies a behavior, not a function. The name was pluralized since in upcoming patches we'll introduce 'normcasespec' which will be one of these values.

json: implement {help} template We should consider add HTML rendering of the RST into the response as a follow-up. I attempted to do this, but there was an empty array returned by the rstdoc() template function. Not sure what's going on. Will deal with it later.

json: implement {helptopics} template

json: implement {manifest} template Property naming was borrowed from `hg files -Tjson`. We omit branch because, again, representation of branches in this template is wonky.

json: implement {shortlog} and {changelog} templates These are the same dispatch function under the hood. The only difference is the default number of entries to render and the template to use. So it makes sense to use a shared template. Format for {changelistentry} is similar to {changeset}. However, there are differences to argument names and their values preventing us from (easily) using the same template. (Perhaps there is room to consolidate the templates as a follow-up.) We're currently not recording some data in {changelistentry} that exists in {changeset}. This includes the branch name. This should be added in a follow-up. For now, something is better than nothing.

help: populate template functions via docstrings We do this for revsets, template keywrods, and template filters. Now we do it for template functions as well.

templater: add consistent docstrings to functions The content of "hg help templating" is largely derived from docstrings on functions providing functionality. Template functions are the long holdout. Prepare for generating them dynamically by defining docstrings for all template functions. There are numerous ways these docs could be improved. Right now, the help output simply shows function names and arguments. So literally any accurate data is better than what is there now.

changeset_printer: hide manifest node for workingctx Because workingctx has no manifest, it makes sense to hide "manifest:" row completely.

changeset_printer: display p1rev:p1node with "+" suffix for workingctx Still templater can't handle workingctx, which will be fixed later.

changeset_printer: handle workingctx in _meaningful_parentrevs()

scmutil: add function to help handling workingctx in arithmetic operation It's unfortunate that workingctx revision is None, which doesn't work well in arithmetic operation or comparison. This function is trivial but will be used in several places.

tests: handle deleted .hg directory (git 2.2.0 and higher) (issue4585) In git 2.2.0 and higher, removing files and directories is changed: removing an object that does not exist returns success rather than failure. As a result, even though .hg/hgrc does not exist, success is returned and the .hg/ directory is removed. To handle this correctly, use 'rm -rf' to allow successful removing for all git versions. The exact changeset where this was introduced in git: 1054af7d04aef64378d69a0496b45cdbf6a0bef2 wrapper.c: remove/unlink_or_warn: simplify, treat ENOENT as success

hgweb: resurrect <span> tag on diffline to fix rendering in monoblue style It was removed at 606a3bf82e30 as a useless tag, but it is necessary to apply "div.diff pre span" style. http://selenic.com/repo/hg/rev/606a3bf82e30?style=monoblue

encoding: use parsers.asciiupper when available This is used on Windows and Cygwin, and the gains from this are expected to be similar to what was seen in 80f2b63dd83a.

parsers: introduce an asciiupper function

parsers: make _asciilower a generic _asciitransform function We can now pass in whatever table we like. For example, an upcoming patch will introduce asciiupper.
