-This patch adds the ability to merge rules into your excludes/includes
-using a ". FILE" idiom. If you specify a name without slashes, that
-filename will be looked for in every subdirectory that rsync visits,
-and the rules found in that subdirectory's file will affect that dir
-and (optionally) its subdirectories.
+This patch adds the --filter option, which implements an improved set of
+include/exclude rules:
+
+ . SINGLE-INSTANCE_MERGE_FILE
+ : PER-DIRECTORY_MERGE_FILE
+ - exclude-pattern
+ + include-pattern
+
+Note that the prefix for a filter rule is NOT optional, and that the
+separating space can be replaced by an equal-sign (=) or an underscore (_),
+if desired. There are also optional modifiers that can be specified for
+the merge-file rules.
+
+A per-directory merge file is one that will be looked for in every
+sub-directory that rsync visits, and the rules found in that sub-
+directory's file will affect that dir and (if desired) its subdirs.
For example:
- rsync -av --exclude='. .excl' --inherit=. from/ to
+ rsync -av --filter :_.rules from/ to
-The above will look for a file named ".excl" in every directory of the
-hierarchy that rsync visits, and it will exclude (by default) names
-based on the rules found therein. If one of the .excl files contains
-this:
+The above will look for a file named ".rules" in every directory of the
+hierarchy that rsync visits, and it will filter names based on the rules
+found therein. If one of the .rules files contains this:
+ *.c
- . .excl2
- . ./.excl3
- *.o
+ : .rules2
+ . .rules3
+ - *.o
+ - /foobar
-Then the file ".excl2" will also be read in the current dir, and all
-subdirs of the current dir (due to the --inherit option). The file
-".excl3" would just be read in for the current dir because its name
-contained a slash.
+Then the file ".rules2" will also be read in from the current dir and all
+its subdirs. The file ".rules3" would just be read in from the current dir
+only. The exclusion of "foobar" will only happen in that .rules file's
+directory because the rule is anchored, which is one way to make a rule
+local instead of inherited (see also the 'n' modifier).

++(include) and which files to skip (exclude). The rules either directly
++specify include/exclude patterns or they specify a way to acquire more
++include/exclude patterns (e.g. to read them from a file).
++
++As the list of files/directories to transfer is built, rsync checks each
++name to be transferred against the list of include/exclude patterns in
++turn, and the first matching pattern is acted on: if it is an exclude
++pattern, then that file is skipped; if it is an include pattern then that
++filename is not skipped; if no matching pattern is found, then the
+ filename is not skipped.
+
+-The filenames matched against the exclude/include patterns are relative
+-to the "root of the transfer". If you think of the transfer as a
+-subtree of names that are being sent from sender to receiver, the root
+-is where the tree starts to be duplicated in the destination directory.
+-This root governs where patterns that start with a / match (see below).
++Rsync builds an ordered list of filter rules as specified on the
++command-line. Filter rules have the following syntax:
++
++itemize(
++ it() x RULE
++ it() xMODIFIERS RULE
++ it() !
++)
++
++The 'x' is a single-letter that specifies the kind of rule to create. It
++can have trailing modifiers, and is separated from the RULE by one of the
++following characters: a single space, an equal-sign (=), or an underscore
++(_). Here are the available rule prefixes:
++
++verb(
++ - specifies an exclude pattern.
++ + specifies an include pattern.
++ . specifies a merge-file to read for more rules.
++ : specifies a per-directory merge-file.
++ ! clears the current include/exclude list
++)
++
++Note that the --include/--exclude command-line options do not allow the
++full range of rule parsing as described above -- they only allow the
++specification of include/exclude patterns and the "!" token (not to
++mention the comment lines when reading rules from a file). If a pattern
++does not begin with "- " (dash, space) or "+ " (plus, space), then the
++rule will be interpreted as if "+ " (for an include option) or "- " (for
++an exclude option) were prefixed to the string. A --filter option, on
++the other hand, must always contain one of the prefixes above.
++
++Note also that the --filter, --include, and --exclude options take one
++rule/pattern each. To add multiple ones, you can repeat the options on
++the command-line, use the merge-file syntax of the --filter option, or
++the --include-from/--exclude-from options.
++
++When rules are being read from a file, empty lines are ignored, as are
++comment lines that start with a "#".
++
++manpagesection(INCLUDE/EXCLUDE PATTERN RULES)
++
++You can include and exclude files by specifing patterns using the "+" and
++"-" filter rules (as introduced in the FILTER RULES section above). These
++rules specify a pattern that is matched against the names of the files
++that are going to be transferred. These patterns can take several forms:
++
++itemize(
++
++ it() if the pattern starts with a / then it is anchored to a
++ particular spot in the hierarchy of files, otherwise it is matched
++ against the end of the pathname. This is similar to a leading ^ in
++ regular expressions.
++ Thus "/foo" would match a file called "foo" at either the "root of the
++ transfer" (for a global rule) or in the merge-file's directory (for a
++ per-directory rule).
++ An unqualified "foo" would match any file or directory named "foo"
++ anywhere in the tree because the algorithm is applied recursively from
++ the
++ top down; it behaves as if each path component gets a turn at being the
++ end of the file name. Even the unanchored "sub/foo" would match at
++ any point in the hierarchy where a "foo" was found within a directory
++ named "sub". See the section on ANCHORING INCLUDE/EXCLUDE PATTERNS for
++ a full discussion of how to specify a pattern that matches at the root
++ of the transfer.
++
++ it() if the pattern ends with a / then it will only match a
++ directory, not a file, link, or device.
++
++ it() if the pattern contains a wildcard character from the set
++ *?[ then expression matching is applied using the shell filename
++ matching rules. Otherwise a simple string match is used.
++
++ it() the double asterisk pattern "**" will match slashes while a
++ single asterisk pattern "*" will stop at slashes.
++
++ it() if the pattern contains a / (not counting a trailing /) or a "**"
++ then it is matched against the full pathname, including any leading
++ directories. If the pattern doesn't contain a / or a "**", then it is
++ matched only against the final component of the filename.
++ (Remember that the algorithm is applied recursively so "full filename"
++ can actually be any portion of a path fomr the starting directory on
++ down.)
++
++)
++
++Note that, when using the --recursive (-r) option (which is implied by
++-a), every subcomponent of every path is visited from the top down, so
++include/exclude patterns get applied recursively to each subcomponent's
++full name (e.g. to include "/foo/bar/baz" the subcomponents "/foo" and
++"/foo/bar" must not be excluded).
++The exclude patterns actually short-circuit the directory traversal stage
++when rsync finds the files to send. If a pattern excludes a particular
++parent directory, it can render a deeper include pattern ineffectual
++because rsync did not descend through that excluded section of the
++hierarchy. This is particularly important when using a trailing '*' rule.
++For instance, this won't work:
++
++verb(
++ + /some/path/this-file-will-not-be-found
++ + /file-is-included
++ - *
++)
++
++This fails because the parent directory "some" is excluded by the '*'
++rule, so rsync never visits any of the files in the "some" or "some/path"
++directories. One solution is to ask for all directories in the hierarchy
++to be included by using a single rule: "+_*/" (put it somewhere before the
++"-_*" rule). Another solution is to add specific include rules for all
++the parent dirs that need to be visited. For instance, this set of rules
++works fine:
++
++verb(
++ + /some/
++ + /some/path/
++ + /some/path/this-file-is-found
++ + /file-also-included
++ - *
++)
+
-+You can merge whole files into an exclude file using a rule that starts
-+with a ". " (a dot followed by a space) and has a filename in place of the
-+pattern. There are two types of merge rules, single-instance and
-+per-directory:
++Here are some examples of exclude/include matching:
+
+itemize(
-+ it() If the filename has no slashes in it, it is a per-directory merge;
-+ rsync scans every directory that it traverses for the named file, merging
-+ its contents (when it exists) at the start of this per-directory
-+ sub-list.
-+
-+ it() If a filename has a slash in it, it is a single-instance merge; the
-+ named file's contents will be merged into the current exclude file,
-+ replacing the merge rule. Thus, you should use the name ./foo instead of
-+ foo if you don't want to scan for "foo" in all the subdirectories in the
-+ transferred tree of directories.
++ it() "- *.o" would exclude all filenames matching *.o
++ it() "- /foo" would exclude a file called foo in the transfer-root directory
++ it() "- foo/" would exclude any directory called foo
++ it() "- /foo/*/bar" would exclude any file called bar two
++ levels below a directory called foo in the transfer-root directory
++ it() "- /foo/**/bar" would exclude any file called bar two
++ or more levels below a directory called foo in the transfer-root directory
++ it() The combination of "+ */", "+ *.c", and "- *" would include all
++ directories and C source files but nothing else.
++ it() The combination of "+ foo/", "+ foo/bar.c", and "- *" would include
++ only the foo directory and foo/bar.c (the foo directory must be
++ explicitly included or it would be excluded by the "*")
+)
+
-+Here's an example exclude file (which you'd specify via the normal
-+--exclude-from option):
++manpagesection(MERGE-FILE FILTER RULES)
++
++You can merge whole files into your filter rules by specifying either a
++"." or a ":" filter rule (as introduced in the FILTER RULES section
++above).
++
++There are two kinds of merged files -- single-instance ('.') and
++per-directory (':'). A single-instance merge file is read one time, and
++its rules are incorporated into the filter list in the place of the "."
++rule. For per-directory merge files, rsync will scan every directory that
++it traverses for the named file, merging its contents when the file exists
++into the current list of inherited rules. These per-directory rule files
++must be created on the sending side because it is the sending side that is
++being scanned for the available files to transfer. These rule files may
++also need to be transferred to the receiving side if you want them to
++affect what files don't get deleted (see PER-DIRECTORY RULES AND DELETE
++below).
++
++Some examples:
+
+verb(
-+ . /home/user/.global_excludes
++ . /etc/rsync/default.rules
++ : .per-dir-filter
++ :n- .non-inherited-per-dir-excludes
++)
++
++The following modifiers are accepted after the "." or ":":
++
++itemize(
++ it() A "-" specifies that the file should consist of only exclude
++ patterns, with no other rule-parsing except for the list-clearing
++ token ("!").
++
++ it() A "+" specifies that the file should consist of only include
++ patterns, with no other rule-parsing except for the list-clearing
++ token ("!").
++
++ it() A "C" is a shorthand for the modifiers "sn-", which makes the
++ parsing compatible with the way CVS parses their exclude files. If no
++ filename is specified, ".cvsignore" is assumed.
++
++ it() A "e" will exclude the merge-file from the transfer; e.g.
++ ":e_.rules" is like ":_.rules" and "-_.rules".
++
++ it() An "n" specifies that the rules are not inherited by subdirectories.
++
++ it() An "s" specifies that the rules are split on all whitespace instead
++ of the normal line-splitting. This also turns off comments. Note: the
++ space that separates the prefix from the rule is treated specially, so
++ "- foo + bar" is parsed as two rules (assuming that "-" or "+" was not
++ specified to turn off the parsing of prefixes).
++)
++
++Per-directory rules are inherited in all subdirectories of the directory
++where the merge-file was found unless the 'n' modifier was used. Each
++subdirectory's rules are prefixed to the inherited per-directory rules
++from its parents, which gives the newest rules a higher priority than the
++inherited rules. The entire set of per-dir rules is grouped together in
++the spot where the merge-file was specified, so it is possible to override
++per-dir rules via a rule that got specified earlier in the list of global
++rules. When the list-clearing rule ("!") is read from a per-directory
++file, it only clears the inherited rules for the current merge file.
++
++Another way to prevent a single per-dir rule from being inherited is to
++anchor it with a leading slash. Anchored rules in a per-directory
++merge-file are relative to the merge-file's directory, so a pattern "/foo"
++would only match the file "foo" in the directory where the per-dir filter
++file was found.
++
++Here's an example filter file which you'd specify via --filter=". file":
++
++verb(
++ . /home/user/.global-filter
+ - *.gz
-+ . .excl
++ : .rules
+ + *.[ch]
+ - *.o
+)
+
-+This will merge the contents of the /home/user/.global_excludes file at the
-+start of the list and also turns the ".excl" filename into a per-directory
-+exclude file whose local contents will be merged into the list in place of
-+the .excl line.
++This will merge the contents of the /home/user/.global-filter file at the
++start of the list and also turns the ".rules" filename into a per-directory
++filter file. All rules read-in prior to the start of the directory scan
++follow the global anchoring rules (i.e. a leading slash matches at the root
++of the transfer).
++
++If a per-directory merge-file is specified with a path that is a parent
++directory of the first transfer directory, rsync will scan all the parent
++dirs from that starting point to the transfer directory for the indicated
++per-directory file. For instance, here is a common filter (see -F):
++
++verb(
++ --filter=': /.rsync-filter'
++)
++
++That rule tells rsync to scan for the file .rsync-filter in all
++directories from the root down through the parent directory of the
++transfer prior to the start of the normal directory scan of the file in
++the directories that are sent as a part of the transfer. (Note: for an
++rsync daemon, the root is always the same as the module's "path".)
++
++Some examples of this pre-scanning for per-directory files:
++
++verb(
++ rsync -avF /src/path/ /dest/dir
++ rsync -av --filter=': ../../.rsync-filter' /src/path/ /dest/dir
++ rsync -av --fitler=': .rsync-filter' /src/path/ /dest/dir
++)
++
++The first two commands above will look for ".rsync-filter" in "/" and
++"/src" before the normal scan begins looking for the file in "/src/path"
++and its subdirectories. The last command avoids the parent-dir scan
++and only looks for the ".rsync-filter" files in each directory that is
++a part of the transfer.
+
-+Additionally, you can affect where the --cvs-exclude (-C) option's
-+inclusion of a per-directory .cvsignore file gets placed into your rules by
-+adding an explicit merge rule for ".cvsignore". For instance, specifying
-+this:
++If you want to include the contents of a ".cvsignore" in your patterns,
++you should use the rule ":C" -- this is a short-hand for the rule
++":sn-_.cvsignore", and ensures that the .cvsignore file's contents are
++interpreted according to the same parsing rules that CVS uses. You can
++use this to affect where the --cvs-exclude (-C) option's inclusion of the
++per-directory .cvsignore file gets placed into your rules by putting a
++":C" wherever you like in your filter rules. Without this, rsync would
++add the per-dir rule for the .cvignore file at the end of all your other
++rules (giving it a lower priority than your command-line rules). For
++example:
+
+verb(
-+ rsync -avC --exclude='. .cvsignore' --exclude-from=foo a/ b
++ cat <<EOT | rsync -avC --filter='. -' a/ b
++ + foo.o
++ :C
++ - *.old
++ EOT
++
++ rsync -avC --include=foo.o -f :C --exclude='*.old' a/ b
+)
+
-+will merge all the per-directory .cvsignore rules at the start of your list
-+rather than at the end. This allows their dir-specific rules to supersede
-+your rules instead of being subservient to them. (The global rules taken
-+from the $HOME/.cvsignore file and from $CVSIGNORE are not affected by
-+this.)
++Both of the above rsync commands are identical. Each one will merge all
++the per-directory .cvsignore rules in the middle of the list rather than
++at the end. This allows their dir-specific rules to supersede the rules
++that follow the :C instead of being subservient to all your rules. (The
++global rules taken from the $HOME/.cvsignore file and from $CVSIGNORE are
++not repositioned from their spot at the end of your rules, however -- feel
++free to manually include $HOME/.cvsignore elsewhere in your rules.)
+
-+Note also that the parsing of any merge-file named ".cvsignore" is always
-+done in a CVS-compatible manner, even if -C wasn't specified (i.e. the
-+rules are always exclude rules (even when specified by an include option);
-+they are split on whitespace; and no special prefixes, list-clearing
-+tokens, or comment characters are honored).
++manpagesection(LIST-CLEARING FILTER RULE)
+
-+See the --inherit option for how to make the rules read from a
-+per-directory merge file inherited by all the subdirectories of the
-+spot where the per-directory rule file was found.
++You can clear the current include/exclude list by using the "!" filter
++rule (as introduced in the FILTER RULES section above). The "current"
++list is either the global list of rules (if the rule is encountered while
++parsing the filter options) or a set of per-directory rules (which are
++inherited in their own sub-list, so a subdirectory can use this to clear
++out the parent's rules).
++
++manpagesection(ANCHORING INCLUDE/EXCLUDE PATTERNS)
++
++As mentioned earlier, global include/exclude patterns are anchored at the
++"root of the transfer" (as opposed to per-directory patterns, which are
++anchored at the merge-file's directory). If you think of the transfer as
++a subtree of names that are being sent from sender to receiver, the
++transfer-root is where the tree starts to be duplicated in the destination
++directory. This root governs where patterns that start with a / match.
+
+ Because the matching is relative to the transfer-root, changing the
+ trailing slash on a source path or changing your use of the --relative
+ option affects the path you need to use in your matching (in addition to
+ changing how much of the file tree is duplicated on the destination
+-system). The following examples demonstrate this.
++host). The following examples demonstrate this.

+-Note that, when using the --recursive (-r) option (which is implied by -a),

+-every path is visited from the top down, so include/exclude patterns get

+-The exclude patterns actually short-circuit the directory traversal stage
+-when rsync finds the files to send. If a pattern excludes a particular
+-parent directory, it can render a deeper include pattern ineffectual
+-because rsync did not descend through that excluded section of the
+-hierarchy.
+-
+-Note also that the --include and --exclude options take one pattern
+-each. To add multiple patterns use the --include-from and
+---exclude-from options or multiple --include and --exclude options.
++manpagesection(PER-DIRECTORY RULES AND DELETE)
+
+-The patterns can take several forms. The rules are:
++Without a delete option, per-directory rules are only relevant on the
++sending side, so you can feel free to exclude the merge files themselves
++without affecting the transfer. To make this easy, the 'e' modifier adds
++this exclude for you, as seen in these two equivalent commands:
+
+-itemize(
+-
+- it() if the pattern starts with a / then it is matched against the
+- start of the filename, otherwise it is matched against the end of
+- the filename.
+- This is the equivalent of a leading ^ in regular expressions.
+- Thus "/foo" would match a file called "foo" at the transfer-root
+- (see above for how this is different from the filesystem-root).
+- On the other hand, "foo" would match any file called "foo"
+- anywhere in the tree because the algorithm is applied recursively from
+- top down; it behaves as if each path component gets a turn at being the
+- end of the file name.
+-
+- it() if the pattern ends with a / then it will only match a
+- directory, not a file, link, or device.
+-
+- it() if the pattern contains a wildcard character from the set
+- *?[ then expression matching is applied using the shell filename
+- matching rules. Otherwise a simple string match is used.
+-
+- it() the double asterisk pattern "**" will match slashes while a
+- single asterisk pattern "*" will stop at slashes.
++verb(
++ rsync -av --filter=': .excl' --exclude=.excl host:src/dir /dest
++ rsync -av --filter=':e .excl' host:src/dir /dest
++)
+
+- it() if the pattern contains a / (not counting a trailing /) or a "**"
+- then it is matched against the full filename, including any leading
+- directory. If the pattern doesn't contain a / or a "**", then it is
+- matched only against the final component of the filename. Again,
+- remember that the algorithm is applied recursively so "full filename" can
+- actually be any portion of a path below the starting directory.
+-
+- it() if the pattern starts with "+ " (a plus followed by a space)
+- then it is always considered an include pattern, even if specified as
+- part of an exclude option. The prefix is discarded before matching.
+-
+- it() if the pattern starts with "- " (a minus followed by a space)
+- then it is always considered an exclude pattern, even if specified as
+- part of an include option. The prefix is discarded before matching.
+-
+- it() if the pattern is a single exclamation mark ! then the current
+- include/exclude list is reset, removing all previously defined patterns.
+-)
+-
+-The +/- rules are most useful in a list that was read from a file, allowing
+-you to have a single exclude list that contains both include and exclude
+-options in the proper order.
+-
+-Remember that the matching occurs at every step in the traversal of the
+-directory hierarchy, so you must be sure that all the parent directories of
+-the files you want to include are not excluded. This is particularly
+-important when using a trailing '*' rule. For instance, this won't work:
++However, if you want to do a delete on the receiving side AND you want some
++files to be excluded from being deleted, you'll need to be sure that the
++receiving side knows what files to exclude. The easiest way is to include
++the per-directory merge files in the transfer and use --delete-after,
++because this ensures that the receiving side gets all the same exclude
++rules as the sending side before it tries to delete anything:
+
+ verb(
+- + /some/path/this-file-will-not-be-found
+- + /file-is-included
+- - *
++ rsync -avF --delete-after host:src/dir /dest
+ )
+
+-This fails because the parent directory "some" is excluded by the '*' rule,
+-so rsync never visits any of the files in the "some" or "some/path"
+-directories. One solution is to ask for all directories in the hierarchy
+-to be included by using a single rule: --include='*/' (put it somewhere
+-before the --exclude='*' rule). Another solution is to add specific
+-include rules for all the parent dirs that need to be visited. For
+-instance, this set of rules works fine:
++However, if the merge files are not a part of the transfer, you'll need to
++either specify some global exclude rules (i.e. specified on the command
++line), or you'll need to maintain your own per-directory merge files on
++the receiving side. An example of the first is this (assume that the
++remote .rules files exclude themselves):
+
+ verb(
+- + /some/
+- + /some/path/
+- + /some/path/this-file-is-found
+- + /file-also-included
+- - *
++ rsync -av --filter=': .rules' --filter='. /my/extra.rules'
++ --delete host:src/dir /dest
+ )
+
+-Here are some examples of exclude/include matching:
++In the above example the extra.rules file can affect both sides of the
++transfer, but (on the sending side) the rules are subservient to the rules
++merged from the .rules files because they were specified after the
++per-directory merge rule.
+
++In one final example, the remote side is excluding the .rsync-filter
++files from the transfer, but we want to use our own .rsync-filter files
++to control what gets deleted on the receiving side. To do this we must
++specifically exclude the per-directory merge files (so that they don't get
++deleted) and then put rules into the local files to control what else
++should not get deleted. Like one of these commands:
+
+-itemize(
+- it() --exclude "*.o" would exclude all filenames matching *.o
+- it() --exclude "/foo" would exclude a file called foo in the transfer-root directory
+- it() --exclude "foo/" would exclude any directory called foo
+- it() --exclude "/foo/*/bar" would exclude any file called bar two
+- levels below a directory called foo in the transfer-root directory
+- it() --exclude "/foo/**/bar" would exclude any file called bar two
+- or more levels below a directory called foo in the transfer-root directory
+- it() --include "*/" --include "*.c" --exclude "*" would include all
+- directories and C source files
