Only two things are fixed in this version.

• Quote ' (apostrophe) as ' in HTML attributes.
• Automatically focus the entry widget when using the non-console Tk command interface.
• Bump version number.

Source, announcement.

Any bugs introduced by this release are intentional April Fool's pranks, not careless mistakes.

• Add [dict getnull] command to simplify the common task of checking if a dict key exists before getting its value. It's very common to want to treat missing values as empty, so this new command makes sense.
• Double the performance of [dehex].
• Simplify [icc::catch] a tiny bit.
• Remove some looping and [set]s in the path normalization code in [getrequest].
• Allow for custom POST content-types such as application/json-rpc.
• Let the application replace [socket] with a custom command, e.g. [tls::socket].
• Add rudimentary history support to the command entry window, used when running Wibble with wish on a platform where there's no [console] command.
• Bump version number. I should do this every time...

Source, announcement.

Just one change this time.

• Fix [icc catch] to properly bytecode the script and to correctly handle [return], etc. inside the script.

Source, announcement.

Some [icc] stuff...

• Improve comments.
• In [deheader], split if-match and if-none-match to be separate header types.
• Always accept exception and timeout events.
• Remove unnecessary ifs.
• Add [icc destroy] to destroy a feed, performing cleanup along the way.
• Add support for exception events to [icc get].
• Guard against [icc destroy] happening in the middle of [icc get].
• Add [icc catch] to get exception events.
• Don't explicitly accept timeout in the coroutine feed.
• In [panic], don't attempt to send errors to the client if not using HTTP.
• Improve demo to use docroot directory if it exists.

Source, announcement.

Major revision!

• Bump revision to 0.2.
• Put zone handlers in "::wibble::zone" namespace.
• Rewrite zone handlers to properly inherit from the existing state dicts.
• Rename the [static], [template], and [script] zone handlers to [staticfile], [templatefile], and [scriptfile], respectively.
• Change [compiletemplate] to [template], which immediately expands the template rather than just compiling it.
• This effectively reverts a change made in the 2010-11-06 revision eaa66764e3.
• Use [template] in zone handlers when appropriate.
• Fundamentally change the format of response headers generated by zone handlers.
• The new format mirrors the format of request headers.
• Change the branch order of [indexfile] to prefer serving index.html.
• Remove caching of template scripts.
• Writing files into the docroot made me nervous...
• Add [contenttype] zone handler to guess content-type from file extension.
• Expand [dumprequest] into [dumpstate] which analyzes the entire state dictionary, not just a request dictionary.
• Remove [enurl] and [deurl].
• Make [enhex] more flexible to make up for the loss of [enurl].
• Update [enquery]/[dequery] to use [enhex]/[dehex] instead of [enurl]/[deurl].
• Add [entime] and [detime] to process HTTP time/date, both relative and absolute.
• Improve correctness of [delist], and teach it to recognize weak tag prefix ("w/").
• Add [enquote] to complement [dequote].
• Add [entag] and [detag] to process HTTP entity tags, including weak tags.
• Add [enheader] to complement [deheader].
• HUGE new feature!
• Update [deheader] for changes in encode/decode procs.
• Add support for cache-control, if-range, and date headers to [deheader].
• Correct if-match and if-none-match support in [deheader].
• Beef up warning support in [deheader].
• Call [dequote] by default in [deheader].
• Eliminate duplicate filters in [icc configure accept].
• Style tweak to [icc put].
• Search for zone handler commands in the new "::wibble::zone" namespace.
• Add cleanup script naming and cancellation capabilities to [cleanup].
• Simplify path normalization regexp in [getrequest].
• Add TE/transfercoding to accept dictionary generation.
• Prefer [dict for] over [foreach].
• Replace [deurl] with [dehex] in [getrequest].
• Add blank response dictionary to initial system dictionary in [getresponse].
• Set charset to utf-8 in various places.
• This change is probably a mistake, since the output will be converted to iso8859-1 anyway.
• Move much of the guts of [process] into [defaultsend].
• In [defaultsend], use the updated [cleanup] facility to close the contentfile.
• Use [enheader] in [defaultsend] to encode the outgoing headers for HTTP.
• Remove header capitalization normalization.
• Add connection: close capability via the return value of [defaultsend].
• Update [process] for the change in [cleanup].
• Have [process] call [defaultsend] or a custom send command supplied by the zone handler.
• This can be used to implement upgrading, e.g. WebSocket and Server-Sent Events http://en.wikipedia.org/wiki/Server-sent_events.
• Move the error log code into [panic] which can be overridden by the application.
• Update panic code to use [dumpstate] instead of [dumprequest].
• In Wibble demo, explicitly initialize zonehandlers to empty.
• This facilitates re-sourcing wibble.tcl in the middle of execution.
• Add sample content-type zone handler configuration.
• Add Tk console to demo.
• Use [console show] if available. Customize it, too.
• If that fails, provide a bare-bones command prompt window.

Source, announcement.

I added a bunch of new features.

• Change "wibble" to "::wibble" to support being sourced, etc. when not in the :: namespace. This was done by JCW's request.
• Add [redirect] zone handler.
• Modify [dirslash] to chain to [redirect].
• Add [forbidden] zone handler.
• Modify [dirlist] to chain to [forbidden].
• Add [string trimright] to end of [compiletemplate]. I can't remember exactly why I did this, but I think it cleans up the output a little bit in some obscure corner case.
• Allow display of multiline data in [dumprequest], so long as the hard-coded string length limit isn't exceeded.
• Remove [resume] and [suspend].
• Remove argument from [getline] and [getblock]; instead derive the socket name from the coroutine name.
• Use the new [icc] commands instead of [resume] and [suspend].
• Strip CR in [enhtml], [enattr], and [enpre].
• Add new [icc] commands.
• Add [cleanup] command.
• Update accept list generation logic to discard elements with a nonpositive qvalue.
• Restructure the POST content-type dispatch code.
• Add text/xml POST support.
• Add default set of cleanup scripts.
• Create an ICC feed for each coroutine.
• Add support for contentchan/contentsize in addition to content and contentfile.
• Don't error on flushing an output socket. (Maybe I should revert this change.)
• Call cleanup scripts when the coroutine terminates.
• Avoid gratuitous use of [namespace code].

Oops. The 501 code didn't work. I forgot to quote the value of the header key, resulting in an extra argument to [dict create]. Also, I removed the query, rawquery, post, and rawpost keys from the request dictionary when no query or post was made. This makes it easier to check if there was a query or a post.

• Fix 501 bug.
• Remove empty query, rawquery, post, and rawpost dicts.

Source, announcement.

Per JBR's suggestion, I removed the [nexthandler $state] calls when $state is unmodified. Instead the zone handler just returns. This winds up having the same effect, because the no-op [nexthandler $state] was changing $system without really modifying it. ;^)

• Remove no-op [nexthandler] invocations throughout Wibble.
• Clarify the comment for [resume].
• Rearrange [suspend] to be a little easier to understand.

Source, announcement.

I changed the zone handler arguments, so any existing zone handlers will have to be rewritten. I hope this new method works better than the fixed request/response approach I had before. Also, I changed the way the coroutines [yield] and are resumed; this should make AJAX work better. (Yes, Wibble supports AJAX!)

• Cutesy CSS changes in [vars].
• Update all zone handlers to receive a unified state dict instead of request and response dicts.
• Update [vars] to display all sub-dicts in $state.
• Pointless wording, capitalization, comment, and indentation changes.
• Fix [dumprequest] to format query the same as post.
• Write [resume] and [suspend] as wrappers around reinvoking the coroutine and [yield].
• Remove [chan names] testing code since it didn't work anyway.
• Update [getline] and [getblock] to use [suspend].
• Rename $zones to $zonehandlers.
• Change $zonehandlers to be a flat list instead of a dict.
• Rewrite [getresponse] to use state dictionaries instead of request/response pairs.
• Don't merge options into the request dict; instead make a separate options dict in $state.
• Fix zone order handling in [getresponse].
• Fix a subtle bug in [getresponse] that can make it replace the wrong state entry in $system.
• Update the [chan copy] code to use [resume] and [suspend].
• Don't install the [chan event] handler in [listen] since it'll be installed by [suspend].

Source, announcement.

Sorry about the blocking [chan copy]. It's fixed now.

• Don't initialize $wibble::zones to empty string. This makes it easier to re-[source] wibble.tcl while it's running.
• Remove some extra [chan close]s. The channel will be closed anyway by the finally clause at the end of [process].
• Add workaround for the Wiki bug that was corrupting [enhtml] and [enattr] (see http://wiki.tcl.tk/27382#pagetoc5da162fc).
• Remove the question mark from [enquery] to make it mirror [dequery]
• Make [chan copy] be non-blocking.
• Add workaround for the "command returned bad code: 2" Tcl bug (see http://wiki.tcl.tk/27382#pagetoc640ac485).
• Spell out "peerhost" and "peerport".
• Re-fix the [namespace code] in [accept] (see http://wiki.tcl.tk/27382#pagetoca290566b).

Source, announcement.

Now that I've finished reorganizing all the Wibble pages, I'm eager to edit them some more! :^)

• Write [dumprequest] to partially "flatten" a request dictionary to make it easier to display.
• Make the output of the vars zone handler much nicer.
• Make the error log nicer too.
• Split the template zone handler into two pieces:
• [template]: Compile *.tmpl files into *.script files.
• [script]: Execute *.script files.
• Add rawtime, time, and port to the request dictionary.
• Completely remove PUT.
• Slightly simplify POST handling.
• Replace [dict for] with [foreach] to support duplicate keys.
• Improve the failsafe ![info exists $request] error log.
• Remove -nonewline option from [log].
• Move \n from the end to the beginning of the line.
• Add new script zone handler to example code.
• Remove special logging of the never-implemented "content" key in the request dictionary.
• Remove [accept] and changed [listen] to use [apply].

Source, announcement.

I've been holding on to these changes for far too long, and I'm glad to finally publish them.

• Add separator comments delimiting major sections of the code.
• Change usage of [dict with request] to cut down on indenting.
• Add many conversion routines:
• [enhtml]: Encode for HTML.
• [enattr]: Encode for HTML tag attribute.
• [enpre]: Encode for HTML <pre>.
• [enquery]: Encode a query string.
• [dequery]: Decode a query string into a list.
• [enhex]: Encode most non-alphanumerics with hexadecimal codes.
• [dehex]: Decode hexadecimal encoding.
• [enurl]: Encode for URLs.
• [deurl]: Decode URL encoding.
• [delist]: Decode header list encoding.
• [dequote]: Decode header quoting.
• [deheader]: Decode HTTP headers. (!!!)
• Actually, [dehex] already existed, named [unhex]. Rename because [enhex] and [unhex] are too similar.
• Modify zone handlers to use new conversion routines, e.g. [enhtml].
• Replace <td><b> with <th> in [vars].
• Simplify the way [dirlist] adds .. to the directory listing.
• Change [applytemplate] to [compiletemplate], which returns the script instead of running it.
• Make [template] cache the result of [compiletemplate].
• Simplify append's arguments in [compiletemplate].
• Add channel closure detection to [getline] and [getblock].
• Revert second-chance [chan gets] in [getline], since I'm not convinced it's necessary (see http://wiki.tcl.tk/27382#pagetoc3c65f636).
• Change the way [nexthandler] and [sendresponse] pass control back to [getresponse].
• Add accept, post, and rawpost to the request dictionary.
• Add Accept*: header handling.
• Add POST handling.
• Unset request dictionary after sending the response to avoid stale data.
• Correct error report charset.
• Incorporate APN's [accept] fix (see http://wiki.tcl.tk/27382#pagetoc8c99f371).

The channel closure detection makes it possible to close connections due to timeouts. This isn't implemented yet, but it would be nice to harden Wibble against basic DoS attacks. (user: andy, tags: trunk)
