[BETA] Patch PE83-2407240 (superseded)

WEBDLG2 version: 2.0.18

Fixed problems:

• Fixed network-related error logging. A session could abort with DLG status 650 (general dialog failure) but the reason was not logged.

• Fixed a rare error condition where the send() system call could return zero. This caused a DLG status 650 without a log message.

• Fixed a JDLG compatibility issue. Although undocumented, JDLG allows a Plugin as Application or System child object. This is used by existing applications, therefore this functionality is now available in WEBDLG2 as well.

[BETA] Patch PE83-2401240 (superseded)

WEBDLG2 version: 2.0.17

Fixed problems:

• Fixed a side effect where in rare cases certain attribute values were not set if an object was synchronized before being displayed for the first time.

  For example, if a ListBox needs to be synchonized before being displayed for the first time because the line order needs to be calculated, it could happen that the rule and singleclick attribute values were not set as expected.

• Fixed a problem where the eloqwebd2 listener could refuse to accept new connections, indicating that the maximum number of clients or sessions are already active. This was caused by a potential overflow of the clients/sessions counters.

• Fixed the JavaScript client error message issued when a new browser tab or window could not be opened.

Patch PE83-2309200 (superseded)

WEBDLG2 version: 2.0.13

  The returned DLG GET EditText.vheight value could be off-by-one if the last line is empty.

[BETA] Patch PE83-2306060 (superseded)

WEBDLG2 version: 2.0.13

Fixed problems:

• Fixed potential race condition which could cause 'App.dlg_DO BUG: whenReady pending' JavaScript client error. The fix in previous patch PE83-2305240 was incomplete.

WEBDLG2 version: 2.0.13

• New attribute: Application.sid : integer, get
  Returns the identifier of the invoking WEBDLG2 session.

• ListBox, PopText: Fixed internal inconsistency after a ListBox or PopText is cleared and new lines/items are added. A subsequent DLG GET .content could then cause an abort of the eloqwebd2 process with a log message like below:

  Assertion failed: bp - val->v.s.p == *content_l_p + nl_cnt
  server panic: Aborting on internal failure, file c_listbox.c, line 3710

• MenuBar: Fixed unexpected height when Dialog is user-resized, as observed with Firefox browser.

• Fixed 'this.currDlg is null' JavaScript client error, internally caused by wrong Dialog.timerrule submission while the Dialog is inactive.

• Fixed various problems related to CloseTimeout and/or DlgQuitStatus and/or DlgQuitRule. If the application is not waiting in DLG DO or POPUP BOX at the moment when the page is unloading, DlgQuitStatus or DlgQuitRule would not be issued afterwards. Also, CloseTimeout was unexpectedly reset to DlgIdleTimeout if the application continues to issue DLG requests.

• Fixed unexpected failure while creating HTTPS listen socket if both TLSCertChainFile and TLSCertKeyFile are configured, as observed with OpenSSL version 3.0.5. A message like below was logged:

  tls_ctx_set_private_key:1270: SSL_CTX_use_PrivateKey_file error:0A080009
  Unable to create HTTPS listen socket: TLS is not configured

Patch PE83-2304060 (superseded)

WEBDLG2 version: 2.0.12

Fixed problems:

• Fixed internal ListBox inconsistency caused by failed ListBoxHeader creation. For example, after a ListBoxHeader cannot be created due to DLG status 655 (duplicate object name), the internal number of columns could become inconsistent.

  This could cause a subsequent abort of the eloqwebd2 process with a log message like below:

  Assertion failed: mi == d->n_col
  server panic: Aborting on internal failure, file c_listbox.c, line 752

Patch PE83-2303290 (superseded)

WEBDLG2 version: 2.0.12

New functionality:

• eloqwebd2.app: The DlgQuitStatus configuration has been added, allowing an application to gracefully quit before it terminates due to inactivity or after the web browser window or tab has been closed.

[BETA] Patch PE83-2303280 (superseded)

WEBDLG2 version: 2.0.12

New functionality:

• eloqwebd2.app: Setting the WarnLeavingPage configuration to 2 always enables the user warning before leaving the page while an application is active, regardless whether or not the current Dialog has the close symbol, and during application development and debugging.

Fixed problems:

• Fixed unexpected DLG protocol failure when invoking DLG SET "Dialog.do",1 on a Dialog where Dialog.do is already active, causing the related session to abort.

Patch PE83-2303220 (superseded)

WEBDLG2 version: 2.0.11

Fixed problems:

• Fixed 'apiReceived … invalid, not idle' JavaScript client error, causing the user interface to stop responding until the document is reloaded.

  This was caused by invoking DLG SET "Dialog.do",1 and then invoking DLG DRAW on a different existing Dialog.

• Fixed new direct Dialog child object added to wrong parent object when the Dialog is already visible. For example, a new HtmlView object, added as direct Dialog child, could become unexpectedly added to the MenuBar.

• Menu: Fixed passing on background color to MenuItems and sub-Menus. The background color is now passed on only if a Menu is a direct MenuBar child object. This ensures consistent separator colors across sub-Menus.

• MenuItem: Fixed visual appearance of disabled items. The visual difference of normal vs. disabled items was too subtle.

• System: Fixed Application start atoms unexpectedly set on new session started via System.start.

[BETA] Patch PE83-2303130 (superseded)

  server panic: Aborting on internal failure, file srv.c, line 2225

[BETA] Patch PE83-2303060 (superseded)

WEBDLG2 version: 2.0.10

Fixed problems:

• Fixed DLG synchronization and Dialog.do race conditions.

• ListBox, MenuItem, TabBox, Tree, POPUP BOX: Fixed visual appearance, vertical alignment of images in HTML content could be inconsistent.

• TabBox: Fixed race condition where focus could be incorrectly set on user tab switch, causing selectedtab unexpectedly being set to previous tab.

• TabBox, Tree: Fixed wrong ruleoverride=1 behavior.

Patch PE83-2302080 (superseded)

WEBDLG2 version: 2.0.7

Fixed problems:

• Dialog: Fixed setting title and/or logoicon while the Dialog is visible had no visual effect.

• eloqwebd2.app: The WarnLeavingPage configuration has been added, allowing to enable/disable to warn the user before leaving the page.

  In addition, the warning is now disabled during application development and debugging, i.e., when a DLG listener is used to start an application.

Fixed problems:

• Fixed a potential use-after-free problem when connections are closed. This could cause an unexpected abort of the eloqwebd2 process, for example with a message like below:

  S0: Assertion failed: BUG: unknown callback
  S0: server panic: Aborting on internal failure, file worker.c, line 145
  

[BETA] Patch PE83-2301190 (superseded)

WEBDLG2 version: 2.0.5

New functionality:

• To prevent unintentional program termination, the user is now warned before leaving the page (e.g. when trying to close the web browser window or tab).

  The warning is issued if the user tries to leave the page while the program is not interactive, i.e., currently outside DLG DO, or when the current Dialog's rule attribute value is zero (i.e., the current Dialog does not display the close symbol in its title bar).

Fixed problems:

• Fixed 'apiReceived op 25: invalid, focus pending' JavaScript client error, causing the user interface to stop responding until the document is reloaded.

  This was caused by invoking DLG SET "Dialog.do",1 and then invoking DLG DRAW on a new Dialog.

• Revised HTTP status 403/404 verbose debug logging, related file system error is now logged when the H3 log flag is configured.

Patch PE83-2301120 (superseded)

• eloqwebd2.uri: Fixed potential eloqwebd2 start failure while booting the system if a configured Path refers to a file or directory where the related file system is not mounted yet.

  The Path configuration is now checked when accessed for the first time, instead of being checked on eloqwebd2 startup.

[BETA] Patch PE83-2212210 (superseded)

WEBDLG2 version: 2.0.3

New functionality:

• eloqwebd2.uri: The Index configuration item has been added.

  Specifies an index file name to be used when the request URI matches a directory in the file system.

Fixed problems:

• Fixed 'setFocus: from… not registered' JavaScript client error, causing the user interface to stop responding until the document is reloaded.

  This was caused by invoking DLG SET "Dialog.do",1 and then opening a new Dialog. The new Dialog then failed to access the previous Dialog's focus object.

• Fixed 'apiReceived op 24: invalid, not idle' JavaScript client error, causing the user interface to stop responding until the document is reloaded.

  This was caused by a client-server race condition.

• Fixed 'BUG: elementsChanged no current Dialog' JavaScript client error.

  This was caused by pressing the context menu mouse button while the Dialog is not interactive.

• MenuBar: Fixed setting visible=0 and sensitive=0 had no effect.

• TabBox: Fixed tab not implicitly selected when focus is set to a contained object.

• TabBox: Fixed sensitive=0 tabs were not displayed.

• TabBox: Fixed setting selectedtab had no effect if the related GroupBox object id is modified afterwards.

• TabBox: Fixed setting selectedtab could have unexpected effects when tabs are deleted afterwards.

• Application development and debugging: When a DLG listener is connected, the eloqwebd2 user agent was not marked as authenticated.

  As a consequence, the eloqwebd2 internal web server returned a 403 Forbidden status for an URI configured with GroupList = @auth.

• eloqwebd2.uri: Fixed ContentType:application/octet-stream HTTP response header unexpectedly returned when configured Path refers to a file.

• eloqwebd2.mime: Specifying media type parameters, for example "charset", was not possible. Parameters were unexpectedly truncated.

  For example: text/markdown; charset=UTF-8
  Truncated to: text/markdown;
