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.

HGIGNORE(5) =========== Vadim Gelfer <vadim.gelfer@gmail.com> NAME ---- hgignore - syntax for Mercurial ignore files SYNOPSIS -------- The Mercurial system uses a file called .hgignore in the root directory of a repository to control its behavior when it finds files that it is not currently managing. DESCRIPTION ----------- Mercurial ignores every unmanaged file that matches any pattern in an ignore file. The patterns in an ignore file do not apply to files managed by Mercurial. To control Mercurial's handling of files that it manages, see the hg(1) man page. Look for the "-I" and "-X" options. In addition, a Mercurial configuration file can point to a set of per-user or global ignore files. See the hgrc(5) man page for details of how to configure these files. Look for the "ignore" entry in the "ui" section. SYNTAX ------ An ignore file is a plain text file consisting of a list of patterns, with one pattern per line. Empty lines are skipped. The "#" character is treated as a comment character, and the "\" character is treated as an escape character. Mercurial supports several pattern syntaxes. The default syntax used is Python/Perl-style regular expressions. To change the syntax used, use a line of the following form: syntax: NAME where NAME is one of the following: regexp:: Regular expression, Python/Perl syntax. glob:: Shell-style glob. The chosen syntax stays in effect when parsing all patterns that follow, until another syntax is selected. Neither glob nor regexp patterns are rooted. A glob-syntax pattern of the form "*.c" will match a file ending in ".c" in any directory, and a regexp pattern of the form "\.c$" will do the same. To root a regexp pattern, start it with "^". EXAMPLE ------- Here is an example ignore file. # use glob syntax. syntax: glob *.elc *.pyc *~ .*.swp # switch to regexp syntax. syntax: regexp ^\.pc/ AUTHOR ------ Vadim Gelfer <vadim.gelfer@gmail.com> Mercurial was written by Matt Mackall <mpm@selenic.com>.
