convert: add a mode where mercurial_sink skips empty revisions.
The getchanges function of some converter_source classes can return
some false positives. I.e. they sometimes claim that a file "foo"
was changed in some revision, even though its contents are still the
same.
convert_svn is particularly bad, but I think this can also happen with
convert_cvs and, at least in theory, with mercurial_source.
For regular conversions this is not really a problem - as long as
getfile returns the right contents, we'll get a converted revision
with the right contents. But when we use --filemap, this could lead
to superfluous revisions being converted.
Instead of fixing every converter_source, I decided to change
mercurial_sink to work around this problem.
When --filemap is used, we're interested only in revisions that touch
some specific files. If a revision doesn't change any of these files,
then we're not interested in it (at least for revisions with a single
parent; merges are special).
For mercurial_sink, we abuse this property and rollback a commit if
the manifest text hasn't changed. This avoids duplicating the logic
from localrepo.filecommit to detect unchanged files.

Many date formats are acceptible. Here are some examples: "Wed Dec 6 13:18:29 2006" (local timezone assumed) "Dec 6 13:18 -0600" (year assumed, time offset provided) "Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000) "Dec 6" (midnight) "13:18" (today assumed) "3:39" (3:39AM assumed) "3:39pm" (15:39) "2006-12-6 13:18:29" (ISO 8601 format) "2006-12-6 13:18" "2006-12-6" "12-6" "12/6" "12/6/6" (Dec 6 2006) Lastly, there is Mercurial's internal format: "1165432709 0" (Wed Dec 6 13:18:29 2006 UTC) This is the internal representation format for dates. unixtime is the number of seconds since the epoch (1970-01-01 00:00 UTC). offset is the offset of the local timezone, in seconds west of UTC (negative if the timezone is east of UTC). ''', 'environment|env|Environment Variables': r''' HG:: Path to the 'hg' executable, automatically passed when running hooks, extensions or external tools. If unset or empty, an executable named 'hg' (with com/exe/bat/cmd extension on Windows) is searched. HGEDITOR:: This is the name of the editor to use when committing. Defaults to the value of EDITOR. (deprecated, use .hgrc) HGENCODING:: This overrides the default locale setting detected by Mercurial. This setting is used to convert data including usernames, changeset descriptions, tag names, and branches. This setting can be overridden with the --encoding command-line option. HGENCODINGMODE:: This sets Mercurial's behavior for handling unknown characters while transcoding user inputs. The default is "strict", which causes Mercurial to abort if it can't translate a character. Other settings include "replace", which replaces unknown characters, and "ignore", which drops them. This setting can be overridden with the --encodingmode command-line option. HGMERGE:: An executable to use for resolving merge conflicts. The program will be executed with three arguments: local file, remote file, ancestor file. The default program is "hgmerge", which is a shell script provided by Mercurial with some sensible defaults. (deprecated, use .hgrc) HGRCPATH:: A list of files or directories to search for hgrc files. Item separator is ":" on Unix, ";" on Windows. If HGRCPATH is not set, platform default search path is used. If empty, only .hg/hgrc of current repository is read. For each element in path, if a directory, all entries in directory ending with ".rc" are added to path. Else, element itself is added to path. HGUSER:: This is the string used for the author of a commit. (deprecated, use .hgrc) EMAIL:: If HGUSER is not set, this will be used as the author for a commit. LOGNAME:: If neither HGUSER nor EMAIL is set, LOGNAME will be used (with '@hostname' appended) as the author value for a commit. EDITOR:: This is the name of the editor used in the hgmerge script. It will be used for commit messages if HGEDITOR isn't set. Defaults to 'vi'. PYTHONPATH:: This is used by Python to find imported modules and may need to be set appropriately if Mercurial is not installed system-wide. ''', "patterns|File Name Patterns": r''' Mercurial accepts several notations for identifying one or more files at a time. By default, Mercurial treats filenames as shell-style extended glob patterns. Alternate pattern notations must be specified explicitly. To use a plain path name without any pattern matching, start a name with "path:". These path names must match completely, from the root of the current repository. To use an extended glob, start a name with "glob:". Globs are rooted at the current directory; a glob such as "*.c" will match files ending in ".c" in the current directory only. The supported glob syntax extensions are "**" to match any string across path separators, and "{a,b}" to mean "a or b". To use a Perl/Python regular expression, start a name with "re:". Regexp pattern matching is anchored at the root of the repository. Plain examples: path:foo/bar a name bar in a directory named foo in the root of the repository path:path:name a file or directory named "path:name" Glob examples: glob:*.c any name ending in ".c" in the current directory *.c any name ending in ".c" in the current directory **.c any name ending in ".c" in the current directory, or any subdirectory foo/*.c any name ending in ".c" in the directory foo foo/**.c any name ending in ".c" in the directory foo, or any subdirectory Regexp examples: re:.*\.c$ any name ending in ".c", anywhere in the repository ''', }
