APACHE 2.x ROADMAP:
Last modified at [$Date: 2002/09/28 17:33:31 $]
DEFERRRED FOR APACHE 2.1
* Source code should follow style guidelines.
OK, we all agree pretty code is good. Probably best to clean this
up by hand immediately upon branching a 2.1 tree.
Status: Justin volunteers to hand-edit the entire source tree ;)
Justin says:
Recall when the release plan for 2.0 was written:
Absolute Enforcement of an "Apache Style" for code.
Watch this slip into 3.0.
David says:
The style guide needs to be reviewed before this can be done.
http://httpd.apache.org/dev/styleguide.html
The current file is dated April 20th 1998!
OtherBill offers:
It's survived since '98 because it's welldone :-) Suggest we
simply follow whatever is documented in styleguide.html as we
branch the next tree. Really sort of straightforward, if you
dislike a bit within that doc, bring it up on the dev@httpd
list prior to the next branch.
WORKS IN PROGRESS (PERHAPS DEFERRED FOR 2.1 or 3.0)
* revamp the input filter syntax to provide for ordering of
filters created with the Set{Input|Output}Filter and the
Add{Input|Output}Filter directives. A 'relative to filterx'
syntax is definately preferable.
* Platforms that do not support fork (primarily Win32 and AS/400)
Architect start-up code that avoids initializing all the modules
in the parent process on platforms that do not support fork.
. Better yet - not only inform the startup of which phase it's in,
but allow the parent 'process' to initialize shared memory, etc,
and create a module-by-module stream to pass to the child, so the
parent can actually arbitrate the important stuff.
* Replace stat [deferred open] with open/fstat in directory_walk.
Justin, Ian, OtherBill all interested in this. Implies setting up
the apr_file_t member in request_rec, and having all modules use
that file, and allow the cleanup to close it [if it isn't a shared,
cached file handle.]
* The Async Apache Server implemented in terms of APR.
[Bill Stoddard's pet project.]
Message-ID: <008301c17d42$9b446970$01000100@sashimi> (dev@apr)
OtherBill notes that this can proceed in two parts...
Async accept, setup, and tear-down of the request
e.g. dealing with the incoming request headers, prior to
dispatching the request to a thread for processing.
This doesn't need to wait for a 2.x/3.0 bump.
Async delegation of the entire request processing chain
Too many handlers use stack storage and presume it is
available for the life of the request, so a complete
async implementation would need to happen 3.0 release.
* Add a string "class" that combines a char* with a length
and a reference count. This will help reduce the number
of strlen and strdup operations during request processing.
Including both the length and allocation will save us a ton
of reallocation we do today, in terms of string manipulation.
OtherBill asks if this is really an APR issue, not an HTTPD issue?
