Changeset 1832306 is being indexed.

If several directories are given in a UserDir directive, only files in the first existing one are checked. If the file is not found there, the other possible directories are not checked. The doc clearly states that they will be checked one by one, until a match is found or an external redirect is performed.

PR 59636.

While at it, add some debug messages to better understand what is performed.

Follow up to r1740928: including NOT_IN_PROXY in NOT_IN_DIR_LOC_FILE is both

incomplete and not backportable, fix it by introducing NOT_IN_DIR_CONTEXT and

restoring NOT_IN_DIR_LOC_FILE to its previous value.

Per ap_check_cmd_context(), NOT_IN_DIR_LOC_FILE actually/really means "not in

any directory context", while the definition itself does not include all the

existing directory contexts (e.g. <Limit>, or <Proxy> before r1740928).

This is a bit of a misnomer, at least, so instead of (ab)using it by adding the

missing contexts (in an incompatible way), let's define NOT_IN_DIR_CONTEXT to

really exclude all directory context (i.e. NOT_IN_DIR_LOC_FILE + NOT_IN_LIMIT +

NOT_IN_PROXY) and use it wherever NOT_IN_DIR_LOC_FILE was used.

This is by itself a major MMN bump (modules not compiled with this commit and

having directives checked against NOT_IN_DIR_LOC_FILE won't be caught the same

way by NOT_IN_DIR_CONTEXT in the new ap_check_cmd_context() code), but with the

below change, 2.4.x should work as before:

- if ((forbidden & NOT_IN_DIR_CONTEXT) == NOT_IN_DIR_CONTEXT) {

+ if ((forbidden & NOT_IN_DIR_LOC_FILE) == NOT_IN_DIR_LOC_FILE) {

if (cmd->path != NULL) {

return apr_pstrcat(cmd->pool, cmd->cmd->name, gt,

- " cannot occur within directory context", NULL);

+ " cannot occur within <Directory/Location/Files/Proxy> "

+ "section", NULL);

}

core, mod_rewrite: introduce the 'redirect-keeps-vary' note

to allow proper Vary header insertion when

dealing with a RewriteRule in a directory

context.

This change is an attempt to fix a long standing problem,

brought up while working on PR 58231. Our documentation clearly

states the following:

"If a HTTP header is used in a condition this header is added

to the Vary header of the response in case the condition

evaluates to true for the request."

This is currently not true for RewriteCond/Rules working in

a directory context, since when an internal redirect happens

all the outstanding response headers get dropped.

There might be a better solution so I am looking forward to

hear more opinions and comments. My goal for a delicate change

like this one would be to affect the least amount of configurations

possible, without triggering unwanted side effects.

If the solution is good for everybody tests will be written

in the suite asap.

mod_rewrite,core: avoid Vary:Host (part 2)

This is a follow up of r1808746 after a chat

with Yann on dev@:

- the HTTP:Host variable suffers from the same problem

- the strcasecmp should be used to allow case-sensitive

comparisons.

- in mod_rewrite is less cumbersome and more clean to just

make the Host header check in lookup_header, so it will

be automatically picked up by every part of the code

that uses it. It shouldn't be a relevant overhead for

mod_rewrite.

mod_rewrite/core: avoid the 'Vary: Host' header

In PR 58231 is was brought up that httpd adds the

Vary: Host header whenever a condition is set to true

in mod_rewrite or in an <If> block.

The https://tools.ietf.org/html/rfc7231#section-7.1.4

section seems to disallow this use case:

"The "Vary" header field in a response describes "

"what parts of a request message, "

"aside from the method, Host header field, [...]"

I had a chat with the folks in #traffic-server and

they don't see much point in having a Vary: Host header,

plus it was reported that Varnish doesn't like it very

much (namely it does not cache the response when

it sees the header, links of the report in the PR).

I don't see much value in this behavior of httpd so

I am inclined to remove this response header value,

but I'd be glad to get a more experienced opinion.

fix for RewriteOptions processing in r1798938

add RewriteOptions LongURLOptimization

Variable expansion in RewriteCond causes strings to be duplicated

out of r->pool. If the variables are long and many conditions

are evaluated, r->pool can get seriously bloated.

Clear the memory used for variable expansion for each set of conditons

once the set of conditions fails to match.

PR60009: RewriteRule local prefix checking update

*) mod_rewrite: When a substitution is a fully qualified URL, and the

scheme/host/port matches the current virtual host, stop interpreting the

path component as a local path just because the first component of the

path exists in the filesystem. Adds RewriteOption "LegacyPrefixDocRoot"

to revert to previous behavior. PR60009.
