vmod-dbrw -- history of user-visible changes. 2019-02-13
See the end of file for copying conditions.
Please send vmod-dbrw bug reports to <gray@gnu.org>
Version 2.4.90 (git)
* req.http.X-VMOD-DBRW-Error
This header is set to 1 by dbrw.rewrite to indicate that an error
occurred during the rewrite.
* New flags: regex and eq
One of this flags can appear in the fourth column of the returned data
set. The 'eq' flag instructs dbrw.rewrite to use exact string match,
instead of regular expressions. The 'regex' flag instructs it to use
regular expression matching. It is the default.
Version 2.4, 2018-12-10
* Support for Varnish version 6.0.2
Version 2.3, 2018-12-08
* SQL idle timeout
For MySQL backend, the default connection idle timeout is set equal to
the value of the MySQL variable 'wait_timeout'. For Postgres, default
idle timeout is not yet implemented.
Idle timeout can be configured using the timeout configuration option,
e.g.:
dbrw.config("mysql", "database=dbrw;user=proxy;timeout=600",
{"select dest,pattern,value,flags from rewrite where
locate(url,'$url') = 1 order by weight asc;"});
* The $() functions in SQL templates
The SQL templates support the use of $() constructs for invoking
built-in functions. So far one function is implemented:
$(urlprefixes PATH)
It expands to comma-separated list of properly quoted pathname
prefixes, constructed from its argument. Optional query part is
stripped off the argument prior to expansion. For example
$(urlprefixes "/local/user/local?a=1")
expands to:
'/local/user/local','/local/user','/local'
This construct is intended for use in SQL IN conditionals, for
example:
SELECT dest,pattern,value,flags
FROM rewrite
WHERE host='$host'
AND url IN ($(urlprefixes $url))
ORDER BY length(dest),value,weight DESC
Version 2.2, 2017-08-10
* Support for Varnish 5.1
Version 2.1, 2017-08-06
* Requires Varnish 4.1
* The --with-varnish-source option has been withdrawn
The configure script relies on pkg-config to determine the location of
Varnish header files and libraries.
Version 2.0, 2014-11-13
Support for Varnish 4.0.
Version 1.0, 2013-07-20
Initial release
