convert all log_error_write() to log_error() and pass (log_error_st *)
use con->errh in preference to srv->errh (even though currently same)
avoid passing (server *) when previously used only for logging (errh)
provide standard types in first.h instead of base.h
provide lighttpd types in base_decls.h instead of settings.h
reduce headers exposed by headers for core data structures
do not expose <pcre.h> or <stdlib.h> in headers
move stat_cache_entry to stat_cache.h
reduce use of "server.h" and "base.h" in headers
EXPERIMENTAL: basic recursive SSI <!--#include virtual="..." -->
Marked experimental since behavior may change in future.
Prior behavior was simpler and treated them all as files included as-is.
New behavior treats all #include virtual="..." targets as SSI files.
In the future, this may change to be a full recursive subrequest and the
virtual path may be treated as a new subrequest and might be something
other than SSI (e.g. might be CGI). This has not been implemented.
Current behavior processes <!--#include virtual="..." --> as static file
Enable new behavior by setting ssi.recursion-max to value other than 0.
ssi.recursion-max = X to set maximum recusion depth
"add recursion to the SSI #include directive"
allow double-quotes, single-quotes or no quote on SSI param values
remove use of PCRE from mod_ssi
fix misspelling of 'unknow' to be 'unknown'
"mod_ssi doesn't accept single quotes"
A new SSI directive, "ssi.conditional-requests", allows to inform
lighttpd which SSI pages should be considered as cacheable and which
should not. In particular, the "ETag" & "Last-Modified" headers will
only be sent for those SSI pages for which the directive is enabled.
"ETag" and "Last-Modified" headers were being sent for all SSI pages,
regardless of whether they were cacheable or not. And yet, there was
no cache validation at all for any SSI page.
This commit fixes these two minor issues by adding a new directive,
"ssi.conditional-requests", which allows to specify which SSI pages
are cacheable and which are not, and by adding cache validation to
those SSI pages which are cacheable. And since sending ETags for
non-cacheable documents is not appropriate, they are no longuer
computed nor sent for those SSI pages which are not cacheable.
Regarding the "Last-Modified" header for non-cacheable documents,
the standards allow to either send the current date and time for
that header or to simply skip it. The approach chosen is to not send
it for non-cacheable SSI pages. "ETag" and "Last-Modified" headers
are therefore only sent for an SSI page if ssi.conditional-requests
is enabled for that page.
The ssi.conditional-requests directive can be enabled or disabled
globally and/or in any context. It is disabled by default.
An index.shtml which only includes deterministic SSI commands such as:
is a trivial example of a dynamic SSI page that is cacheable.
