i18n-ru: fix misprints

shelve: some docstring cleanups

dirstate.status: return explicit unknown files even when not asked dirstate.walk will return unknown files that were explicitly requested, even if listunknown is false. There's no point in dropping these files on the floor in dirstate.status. This has no effect on any current callers, because all of them assume the unknown list is empty and ignore it. Future callers may find it useful, though.

shelve: add minimal documentation to all functions There is a lot of functions in this extension. We had a small documentation help people getting started.

shelve: use the class constant in the clear method This class attribut is used everywhere else. Not using it in clear will get us in trouble sooner or later.

hgweb: fix unstoppable loading of graph when no more results When a user reaches the end of repo history with graph view, it (unsuccessfully) tried to load more entries. This patch disables further loading attempts.

hgweb: remove now unnecessary explicit header() and footer() They became unnecessary after allowing custom-named entries in templates.

hgweb: replace 'shortlog' with 'changelog' in raw changelog template

shelve: drop pickle usage Pickle was used to the `shelvedstate` file. However the content of the file is very simple and we can handle serialisation ourself. Not using pickle is a net win. Note incrementing the format version as no releases have been done so far.

store: use "vfs.exists()" instead of "os.path.exists()"

context: use "vfs.lstat()" to examine target path instead of "os.path.*" This patch gets stat object of target path by "vfs.lstat()", and examines stat object to know the type of it. This follows the way in "workingctx.add()". This should be cheaper than original implementation invoking "lexists()", "isfile()" and "islink()".

context: use "vfs.lstat()" instead of "os.lstat()"

context: use "vfs.lstat()" instead of "os.lstat()" This patch also changes paths added to "rejected" list from full path (referred by "p") to relative one (referred by "f"), when type of target path is neither file nor symlink. This change should be reasonable, because the path added to "rejected" list is relative one, when "OSError" is raised at "lstat()".

changelog: use "vfs.fstat()" instead of "util.fstat()" Just invoking "os.fstat()" with "file.fileno()" doesn't require non ANSI file API, because filename is not used for invocation of "os.fstat()". But "util.fstat()" should invoke "os.stat()" with "fp.name", if file object doesn't have "fileno()" method for portability, and "fp.name" may cause invocation of non ANSI file API. So, this patch makes the constructor of appender class invoke "util.fstat()" via vfs, to encapsulate filename handling.

changelog: use "vfs.rename()" instead of "util.rename()"

vfs: add "open()" for newly added code paths which open files via vfs This patch replaces "open()" by own "__call__()" defined in derived classes at the first invocation, for efficiency of succeeding invocations.

bookmarks: use "vfs.utime()" instead of "os.utime()"

bookmarks: use "vfs.unlink()" instead of "util.unlink()"

cmdutil: use None as default value for "function pointer" instead of False Less type confusion.

graft: make skip messages more helpful This makes it possible for the user to understand and accept or work around what is happening.

convert: update source shamap when using filemap, just as when not using filemap The reverse mapping was introduced in 2147a734dcf9 to make roundtrip conversions possible ... but it did not work when using filemap. Roundtrips with filemaps will of course only work flawlessly if inverse mappings are used. Especially, if a lossy convert mapping is used in one direction, then only linear lines of development can be converted in the other direction. With this constraint convert will do the right thing by assuming that excluded files haven't been changed.) A test case with general coverage of hg-hg roundtrips with filemap is added. (There a cases where adding records of converted revisions to the shamap in the source repository doesn't work - especially when converting the same repo to several other repos and back. It would arguably be better if convert only updated the shamaps in the target repo but read shamaps from both the source and and target repo ... but that is a different story. Making the stuff we have work consistently is step forward no matter what.)

convert: introduce hg.revs to replace hg.startrev and --rev with a revset The existing knobs for controlling which revisions to convert were often insufficient. Revsets is a shiny hammer that provides a better solution. Revsets has been introduced in --rev handling in a lot of other places while being more or less backwards compatible. Doing the same here would be a much more elegant ... but that would unfortunately not work in this case. "--rev 7" used to mean revision 0 to 7 - it would be an unacceptable change if it suddenly just meant revision 7. Instead we introduce a new configuration setting. It will only work for Mercurial repositories so adding a new commandline option for it would not be a nice solution. There is no way to use the fancy deprecation markup for configuration settings so we just remove the documentation of hg.startrev.
