The headers stored for cached pages ended in a newline, which caused header("") to get called when serving the page.
On some PHP versions (happens on 4.3.3 at least, but not in 5.0), PHP adds a blank header to the HTTP request (i.e. just \r\n) which ends HTTP headers prematurely and adds a newline at the beginning of the page.
This was not an issue before because we output HTML. Now that we have GZip compression, this bug caused corruption of the output. :P
*phew*
* The _validate hook and the _nodeapi('validate') hook of the node API (1) no longer take an 'error' parameter and (2) should no longer return an error array. To set an error, call form_set_error().
* The _form hook of the node module no longer takes a form hook and should not worry about displaying errors. Ditto for _nodeapi('form_post') and _nodeapi('form_pre').
CHANGES
-------
+ Introduced tabs. First, we extended the menu system to support tabs. Next, a tab was added for every link that was (1) an administrative action other than the implicit 'view' (2) relevant to that particular page only. This is illustrated by the fact that all tabs are verbs and that clicking a page's tab leads you to a subpage of that page.
+ Flattened the administration menu. The tabs helped simplify the navigation menu as I could separate 'actions' from 'navigation'. In addition, I removed the 'administer > configuration'-menu, renamed 'blocks' to 'sidebars' which I hope is a bit more descriptive, and made a couple more changes. Earlier, we already renamed 'taxonomy' to 'categorization' and we move 'statistics' under 'logs'.
+ Grouped settings. All settings have been grouped under 'administer > settings'.
TODO
----
+ Update core themes: only Xtemplate default supports tabs and even those look ugly. Need help.
+ Update contributed modules. The menu() hook changed drastically. Updating your code adhere the new menu() function should be 90% of the work. Moreover, ensure that your modue's admin links are still valid and that URLs to node get updated to the new scheme ('node/view/x' -> 'node/x').
+ Introduced two new functions:
1. form_set_error($name, $message): files an error against the form
element with the specified $name.
2. form_has_errors(): returns true if errors has been filed against
form elements.
+ Updated the form handling:
1. The form_ functions will add 'class="error"' when a form field
has been found to be erroneous.
2. The error message is passed to theme_form_element() when the
particular form field has been found to be erroneous.
+ I updated the user and profile module to take advantage of these new
functions.
+ IMPORTANT: the _user() hook changed. The 'validate' case should no
longer retun an error message when something goes wrong but should
set it with form_set_error().
administrators will be able to define a custom 403 page, just as they
can define 404 pages now.
This needs to be documented in the "Changes since / migrating to ..."
pages.
+ only adds an optional parameter to url() and l(), so individual links
can be set to be absolute
+ modifies drupal_goto() to accept the parameters of url() without the
$absolute parameter, so cleaner invocations can be used
+ rework of some code in node_feed, making it much better to look at
(the current code uses foreach with an immediate brake to get the first
key of the associative array, geeeeez)
+ added xml:base to the rss tag generated by node_feed()
+ set all user mail URLs to be absolute
+ fix a small fragmented URL in user.module
they will be part of the same documentation group, as well as created a new
'formatting functions' group and added a lot of docs for them. Also fixed
some small errors reported by the doxygen parser.
containing two elements, the first being the requested title, and the second being
the result list. Advantages:
* Cleaner search code in common.inc
* Po extraction is possible and works fine
* No hardcoded exceptions for node and comment modules, since any module can
return results in order of relevance (or another order)
- Adds drupal_set_header() and drupal_get_headers().
- Cache now stores custom headers.
- Replace theme_head() with drupal_get_html_head(), added drupal_set_html_head().
- Added RSS autodiscover links to node, blog and taxonomy pages.
+ Added drupal_http_request().
+ Replaced rssfeeds with OPML feed subscription list.
+ Added support for pubDate.
+ Added support for conditional gets using ETag and Last-Modified.
/**
* Wrapper around xml_parser_create() which extracts the encoding from the XML
* data first and sets the output encoding to UTF-8. This function should be
* used instead of xml_parser_create(), because PHP's XML parser doesn't check
* the input encoding itself.
*
* This is also where unsupported encodings should be converted.
* Callers should take this into account: $data might have been changed after
* the call.
*
* @param $data The XML data which will be parsed later.
*/
To do this cleanly, I reorganised some bits of system.module: there is now a generic handler available for simple variable-get/set based configuration pages. Look at filter_admin() or system_view() for example usage.

tags.
To be discussed and investigated: when a form element has no title an empty
<label> tag will be emitted (eg. "remember me" checkbox). This doesn't make
sense but is our best option for now.
+ Simplified cache logic in drupal_get_path_map().
+ Added check to see if errors should be reported to error_handler().
+ Use proper db_query() syntax in throttle(), and use $_ENV instead of
getenv().
+ Changed fix_gpc_magic() to use array_walk (C functions will always be
faster), and renamed _fix_gpc_magic_array() to _fix_gpc_magic().
+ Renamed $node in array2object() to $array.
+ Renamed $node in object2array() to $object.
+ Minor other coding method tweaks.
Contributed themes and modules need to be updated:
- modules: status() is no more; use drupal_set_message() instead.
- themes: use drupal_get_message() to check for status messages and
visualize them.
* fixes all doxygen warnings [#]_ in the current code base
+ changes @param style from phpDocumentor (@param type $var desc) to doxygen (@param $var desc)
+ documents all undocumented parameters
+ escapes / fixes html warnings
+ fixes @defgroup in theme.inc
* adds more groupings [#]_
+ drupal_{set|get}_title, drupal_{set|get}_breadcrumb
+ pager.inc: pager_api (pager_query(), pager_display()), pager pieces
* adds a new group "themeable" which contains all themeable functions.

This adds session support for anonymous users and fixes a bug/typo.
1. changed rid for user #0 from 0 to 1 (rid 1 == anonymous user) to make
inner join work.
2. replaced "if ($user .." by "if ($user->uid .." because now $user is
always set (my previous change probably caused this).
3. db_next_id("user_uid") -> db_next_id("users_uid");

I repeat:
"This adds session support for anonymous users and fixes a bug/typo."
- Made sure the 'Topic' title is only shown above the topics, not the icons.
- Automatically shorten the username when it is too long. I implemented this
as part of format_name() and could therefore nuke some code in the
statistics module. This is change is somewhat experimental and I'm willing
to revert or change this if a number of people aren't too happy with this
behavior.
- Left align the dates and authors: makes it easier/faster to scan.
- Made the little tablesort arrows clickable.
- Applied modified version of mathias' 0073 patch: node form name.
$params["options"] is now an array so some contrib modules might
need minor changes.
- Applied mathhias' 0074 patch: missing access check on who is new
block.
are those that have the "bypass input data check" permission set. Should
address bug #2147.
- Improvement: simplified index.php and modules/admin.module.
- Bugfix: fixed broken links in bloggerapi documentation. Patch by Chris
Johnson. Fixes bug #2030.
- Bugfix: fixed the date shown on a book module preview. Reported as part
of bug #2097.
- Bugfix: fixed broken URL in the book module documentation.

detected. This will be logged in the watchdog. With help from Marco.
- Fixed translation issue in the archive module. Patch by Gerhard.
- Removed dead parameter from variable_get(). Patch by Chris Johnson.
Fixes bug #2111.
- Improved input checking of taxonomy module. Patch by Gerhard.
Fixes bug #2112.
the fix was somewhat simpler. Fixes bug #2003.
- Bugfix: fixed problem with voting on certain poll pages. Patch #37 by Al.
- Improvement: removed stupid descriptions from profile module.
- Bugfix: fixed translation problems in the user module and the block module. Patch by Stefan.
- Improvement: made it impossible to delete user role #1 and #2. Patch #38 by Al.
- Improvement: fixed the "Allowed HTML tag" issues. Makes for better code and improved usability. Patch #35 by Al.
NOTE: as soon the compose tips make their way into CVS, most of this code can be removed.
- Improvement: renamed some theme functions of the forum module for sake of consistency/readability. Patch #2 by Kristjan.
- Improvement: usability improvements to the Xtemplate theme. Patch #3 by Kristjan.
- Improvement: CSS'ified the book module pages. Patch #3 by Al. (I simplified the "l
ocation" part. Al's approach gave you a bit more power but I'm not sure anyone wants
to change that. Besides, this will change as soon we integrate the menu system so I kept it easy for now.)
- Bugfix: fixed the defaults for blocks in database.mssql so the NOT NULL fields get values. Patch by Kjartan.
- Bugfix: changed check_form() to use htmlspecialchars() instead of drupal_specialchars() as this caused Drupal to emit incorrect form items in presence of quotes. Example:
<input type="submit" class="form-submit" name="op" value="Submit "top nodes" block changes" />
IMO, drupal_specialchars() is better called xmlspecialchars() to avoid confusion.
- Bugfix: when an anonymous user visits a site, they shouldn't see any content (except the login block, if it is enabled) unless they have the "access content" permissions. Patch by Matt Westgate.
- Improvement: improved the error checking and the error messages in the profile module. Updated the code to match the Drupal coding conventions. Modified patch from Matt Westgate.
- Improvement: don't generate the <base href=""> tag in the base theme; it is already emitted by theme_head(). Patch by Kristjan.
- Improvement: don't execute any SQL queries when checking the permissions of user #1. Patch by Kjartan.
- Improvement: made a scalable layout form that works in IE and that behaves better with narrow themes. Part of patch #51 by Al.
- Improvement: removed some redundant print statements from the comment module. Modified patch from Craig Courtney.
- Bugfix: made the "moderate" field behave. Patch 0030.queue.module.help.and.settings.form.patch by Al.
- Documentation: revised a large part of the help texts / documentation! Al's 0024.* patches.
- Documentation: added a glossary to the help module. Patch 0025.help.module.glossary.patch by Al and Michael.

- CSS improvements: patch 0026.admin.css.small.improvement.patch by Al.
- Updated the MAINTAINERS file.
==> This fix requires to run update.php!

- GUI improvements: small fixes to Xtemplate. Patch '0022.xtemplate.css.patch' by Al.
TODO:
- Some modules such as the buddy list module and the annotation module in the contributions repository are also using session_register(). They should be updated. We should setup a task on Drupal.
- There is code emitting '<div align="right">' which doesn't validate.
- Does our XML feeds validate with the charset changes?
- The forum module's SQL doesn't work properly on PostgreSQL.
to avoid XSS attacks! Patch by Al, Moshe, Marco, Kjartan and me.
- Bugfix: the admin module does now import drupal.css prior to admin.css.
Patch by me.
- Bugfix: the admin module was still emitting a <base href=""> tag. I
removed this as it is been taken care of by theme_head(); Patch by me.
- Bugfix: made the tracker module's pager only consider published pages.
Patch by Moshe.

look nicer. Patch by Moshe and Al.
- CSS improvements: added CSS classes for form elements. Patch by Al.

CSS but apparently others browsers such as Konqueror do.
- Xtemplate improvements: changed the color of the selected day in the
archive module's calendar. Patch by Al.
- Usability improvements: made the "birthday" field of the profile module
look nicer. Patch by Al.
------
- TODO: it might be a good idea to emit the following meta tag in the
theme_head() function:
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
Currently, some themes (and modules!) emit this while others don't. This
would also make it possible to change the charset site-wide.
- TODO: now we added support for td.dark and td.light to drupal.css, maybe
it can be removed from admin.css as well as xtemplate.css?
components such as lists, form items, removes an ugly hack from the
archive module and should fix the poll problem (although it doesn't
Opera/Konqueror).
a little hack that sometimes patches the request_uri(); I don't think
this should trigger in first place. If it does, let me know the URL of
the form as well as the referring page. (If this needs fixing after all,
fixing this _inside_ request_uri() might be a better solution.)
of the "footer" hook (and because of the existence of the page module).
This caused the node view counter to be incremented twice per page view,
the cache being set twice, etc. Quite a bug.
- Fixed a typo in the MSSQL database scheme. Patch by Michael Frankowski.
- Removed dependency on "register_globals = on"! Patches by Michael Frankowski.
Notes:
+ Updated the patches to use $foo["bar"] instead of $foo['bar'].
+ Updated the INSTALL and CHANGELOG files as well.
- Tiny improvement to the "./scripts/code-clean.sh" script.
PHP's XML-RPC library is enabled.
- Renamed 'xmlrpc_encode' to '_xmlrpc_encode' to avoid redeclaration when
PHP's XML-RPC library is enabled.
- Removed 'if (funcion_exist("xmlrpc_encode"))' check from common.inc.
- Added node_admin_settings() to let users set node defaults.
* Added _nodeapi("conf")
- Modified form_checkbox() to unset options. (Modified the patch from Ax.)
- Removed the _save() hook.
- Fixed a logical flaw in field_get() and field_set() which would break
moderation.
- Moved some admin menus around and cleaned up some typos.
invoke module_init() *after* the locale module has been initialized. The
system module was translating string from within its init hook which is now
possible/allowed.
