- adjust open-clause in SURFLETS
|
||||
- split surflet-handler file into multiples.
|
||||
- add more comments to files.
|
||||
- change assoc to assq in get-header in surflets.
|
||||
- Add note that make-redirect-response is for CGI only
|
||||
- Add note to make-redirect-response that the browser won't notice the
|
||||
- redirect.
|
||||
- Add possibility to generate error-responses.
|
||||
- Add-simple does not work.
|
||||
- Simple SUrflet does not work.==> Bug in GET-BINDINGS of POST req.s
|
||||
>>NO PROBLEM on other sites: * ??Spaceships' last step does not work.
|
||||
- Surflet administration does not work.
|
||||
- *POST-cache* in surflets.scm should be threadsafe. (it is)
|
||||
- killing sessions results in error
|
||||
>>MOVED to LATER: * Simple Surflets cannot have extra HTML.
|
||||
- Uppercase some surflet names in strings.
|
||||
- Remove surflet-prefix from surflet-handler options.
|
||||
- Remove return-continuation from instance.
|
||||
- DELETE-CONTINUATION in surflet-handler: obtain lock before looking
|
||||
- for continuation table.
|
||||
- Rewrite LOAD-SURFLET in GET-SURFLET-RT-STRUCTURE in surflet-handler
|
||||
- thus it is may stand alone.
|
||||
- look for resume-url-ids only in the filename, not in the path part.
|
||||
>>MOVED to LATER: * ?Only one thread for all surveillance
|
||||
- Use convert for gnuplot's output.
|
||||
>>>* Better structure for input-fields: changing default values
|
||||
>>>* Change representation of Simple SUrflet objects to
|
||||
>>> record types.
|
||||
>>>* Implement vectors with WRITE-BLOCK (see doc/io.txt)
|
||||
- DISCOURAGED: SUrflets get only bindings?
|
||||
- add-html self-link is wrong, same in add-surflet.scm
|
||||
- unify returned-via? and input-field-binding in dispatcher
|
||||
?? not reproducable Gateway error while accessing non existing surflet continuation
|
||||
- There's a TODO at the end of admin-profiling
|
||||
- use scheme-with-scsh in packages.
|
||||
- input-field-binding-check in admin-handler (should-be input-field-value)
|
||||
- rename set-options-session-lifetime to set-options-session-lifetime!
|
||||
- dito for adjust-timeout
|
||||
>>>It is useful for initial requests or simple session-id recovering
|
||||
>> unexport instance-session-id: no use cognizable
|
||||
- disentangle form-query (surflets/simple-surflet-api)
|
||||
* alias for extract-single-binding (extract/single) and extract-bindings
|
||||
(extract)?
|
||||
- outsource some parts from surflets.scm; make them extra modules
|
||||
- export conversion-rules
|
||||
- remove l.320: why can't ... be deleted correctly?
|
||||
- add session-alive?
|
||||
- (define (session-alive? session-id)
|
||||
- (assoc session-id (get-sessions)))
|
||||
- add send-html-string that gets a string and sends a no-caching html
|
||||
- export status-code Makro for surflet-handler's responses
|
||||
- three layer structures:
|
||||
(a) Usual User: surflets:
|
||||
surflets/send-html
|
||||
(b) Advanced User:
|
||||
. Access to (his) session
|
||||
# surflets/sessions
|
||||
. own conversion rules
|
||||
# surflets/my-sxml
|
||||
. continuations
|
||||
# responses
|
||||
# send/.. primitives:
|
||||
# surflet-handler/primitives:
|
||||
(export
|
||||
surflet-response-constructor
|
||||
surflet-response-selectors
|
||||
send/.. primitives
|
||||
send-error
|
||||
(status-code :syntax))
|
||||
(c) Adminstrative User: Full acccess to surflet-handler
|
||||
Naming convention: Avoid "surflet-handler/.." in name, if there is
|
||||
no semantical context to the surflet-handler (e.g. exceptions:
|
||||
responses, status-code, requests)
|
||||
>>>* Problem: surveillance-thread: obtains the lock to remove the session
|
||||
entry, if the time-to-live is zero. It may happen that another
|
||||
thread is waiting for this lock just to do something with the killed
|
||||
session. This will encounter an error where the lock for the session
|
||||
table is not released. Thus, we have to use error-handler
|
||||
everywhere, where we use *session-table-lock*
|
||||
>> Some argument checks added with commit 1.64 of
|
||||
surflet-handler.scm
|
||||
- >> WITH-LOCK
|
||||
- add GET-SESSION to surflet-handler
|
||||
- alist-administration in make-callback/make-annotated-address
|
||||
(make-valued-address) -> (url [value] -> return-address)
|
||||
returned-via? will return the value or #f if none was given
|
||||
- change data structure for input-fields
|
||||
- add annotated versions for input-field constructors
|
||||
* make subset lists for some parts
|
||||
- structure WITH-LOCK from sunterlib (add to load-surflet-server.scm)
|
||||
and/or DYNAMIC-WIND
|
||||
- only ship ID of session / continuation to the user (--> if he saves
|
||||
the session, it will never be GC'ed otherwise)
|
||||
- in add-raw: remove link to add-html.scm
|
||||
- remove bug: strings in urls seem to be html-quoted twice
|
||||
- at simple-surflet-api: bigger distance between following
|
||||
radio-input-fields
|
||||
- surflet-handler 552: session-id instead of instance-session-id
|
||||
|
||||
send error 411 "Length required" in get-content-length (bindings.scm)
|
||||
if the content-length-header is missing.
|
||||
|
||||
don't use with-real-input-field, use let and cadr instead. (?)
|
||||
|
||||
use internal-error, if surflet fails, not bad gateway
|
||||
|
||||
don't let callbackfunctions return.
