py3: drop unrequired code from __init__.py Once we are using pycompat.open(), we don't need this hack to convert the second argument to unicodes. So removing this.

py3: add pycompat.open and replace open() calls open() requires mode argument as unicodes on Python 3. This patch introduces pycompat.open() which is inserted to files using transformer and replaces builtins.open() calls.

localrepo: deprecate 'repo.opener' (API) The "new" 'repo.vfs' attribute have been around for almost 5 years. I think we can deprecate the old form now ;-)

statichttp: use 'repo.vfs' as the main attribute We are about to deprecate the repo.opener attribute, we prepare the static http code to be ready for this change.

clonebundle: use 'repo.vfs' instead of 'repo.opener' The later is a 5 years old form.

localrepo: deprecated 'repo.wopener' (API) The "new" 'repo.wvfs' attribute have been around for almost 5 years. I think we can deprecate the old form now ;-)

localrepo: add some comment about role of various vfs object This should make things clearer for most people.

tests: un-nest the `order` repo in test-rebase-scenario-global This wasn't hurting anything, but it's more in line with how we manage other tests.

osx: install bash and zsh completions by default The zsh location appears to be on the default $fpath for zsh. bash, on the other hand, appears to have no default location for completion scripts, so we follow the lead of Apple's Git distribution and select a semi-arbitrary place in /usr/local for the file.

util: add allowhardlinks module variable To enable extensions to enable hardlinks for certain environments, let's move the 'if False' to be an 'if allowhardlinks' and let extensions modify the allowhardlinks variable. Tests on linux ext4 pass with it set to True and to False.

revert: remove set(mf) because it's O(manifest) The revert code had a 'set(manifest)' line in it, which has a runtime equivalent to the size of the manifest. With alternative manifest implementations, like treemanifest, this can be extra expensive. Let's rewrite it to be O(changes) instead of O(manifest size).

share: add --relative flag to store a relative path to the source Storing a relative path the source repository is useful when exporting repositories over the network or when they're located on external drives where the mountpoint isn't always fixed. Currently, Mercurial interprets paths in `.hg/shared` relative to $PWD. I suspect this is very much unintentional, and you have to manually edit `.hg/shared` in order to trigger this behaviour. However, on the off chance that someone might rely on it, I added a new capability called 'relshared'. In addition, this makes earlier versions of Mercurial fail with a graceful error. I should note that I haven't tested this patch on Windows.

minirst: support passing admonitions into findadmonitions() and parse() This will allow consumers to declare a custom list of admonitions to parse. Without this patch, custom admonitions would get removed when prunecomments() is run. We could add an argument controlling whether prunecomments() is run. However, it is better to convert the "paragraph" block to an "admonition" block so consumers don't have to parse for custom admonitions.

minirst: dynamically compile admonitions regexp Currently, parsing admonitions uses a static regular expression created from a pre-defined list of admonitions. A future patch will introduce a feature that needs to parse custom admonitions. Prepare for this by compiling the admonitions regular expression during each function invocation. Strictly speaking, there is a slight performance loss here. But we only run this code as part of displaying help text. I don't think the loss will be noticeable and I don't think we care if it were.

minirst: detect bullet lists using asterisks Previously, the "bullet" regular expression excluded the asterisk ('*') as a character denoting a bulleted list. Why I'm not sure because the asterisk seems to be the canonical bullet character in reST these days. This patch makes asterisk-prefixed lines parse as bulleted lists.
