Important

=========

 ! downloads_check.php - doesn't handle correctly failed downloads. We should

 do something about it.

 ! For MSSQL column and table quotes should be changed from " to []. Yes, for

 this we should introduce opening and closing quote :(

 ! Prevent entering custom plot mode if not supported

Cache Engine

============

 - We are currently just skipping databases which are failed to connect to the

 data source (request.pph/GetSources/catch block). In case if we are caching the

 data this prevents administrator from getting information about the problems.

 - If we change use_subsecond flag without dropping the cache, the ADEI will

 report channel inconsistency (not clarifying the issue). Since, we will get

 two extra columns in the caching table. The proper error message should be

 reported in this case.

 - At the moment, We can't really use non [\w\d_] symbols in gids if md5 

 postfixes are switched off. Otherwise, this symbols are stripped from the 

 postfixes (for the sake of table names) and then the check for cached tables

 is failing (it reconstructs gid basing on the table names). Some, other things

 may fail as well.

 For the check, we can try to ignore the inappropriate symbols (only if md5 is

 switched off). So, the stripping should be performed by caching code.

 - In the non-0 caching modes, the last interval is not displayed. Why cache is

 not returning the last point?

VIEWS

=====

 - Support non-fitting timestamps in the scatter plot with resolution 0.

Filters

=======

 - While requesting last record (or potentially several last entries), it is

 possible to get empty response if the last record while be rejected by the

 configured filters. Iteratively increase limit? When fixed and may be 

 universally used, shall we introduce a 'limit' option instead of making 

 complex 'window' parsing?

 - If we may want to filter the rows based on value of certain channel, we

 may get problems with db_mask. It will be applied before the filter and

 only selected channels will pushed through. Using READER_Filter interface

 we may find the required columns, but will should ensure that the data

 required for filter is provided (introduce db_mask_required parameter of 

 filter?)

Virtual

=======

 - Support "__" in group names in SourceTree

Download Manager

===============

 ! Download manager does not respect "setup"

 ! Show details of Downloads Manager button while not work if data is not 

 from default setup.

 ! download_manager.js is updating too often (due to adei.updater.Update()

 calls). This should be somehow fixed. As well it refers dlmanager.Request()

 which uses variable name set in correspndent module. This is completely 

 insane and should be fixed.

ZEUS Reader

===========

 ! Interlock between Full Backup and other calls in ZEUSReader. This is

 critical. If not prevented, the cache may start while configuration is

 partially dropped and not yet reloaded. This may result in rejecting 

 some data vectors because of invalid number of records, etc.

RRD Reader

==========

 ! Axes are not always cleaned when changing to different group, 

 with RRD source 

 - Do not list empty groups in RRDReader

Web Frontend

============

 - Rising memory consumption with Firefox (and I guess other browsers)

 - Passing away pointer to "this" in JS-constructors may be problematic (no 

 errors, but this will be an incorrect "this").

 - Chromium and arora doesn't respect disabled states while setting initial 

 choices of select (scatter plot options). Just force proper selection.

 - Opera/Chrome do not resize source popup properly on axes update. If width

 of axes tab grows, it just gets out of popup borders.

 - The following case: We made a selection and opened one of the popups. The

 forced graph update have canceled selection. However, the selected values

 are still present window configuration dialog.  Should we cancel them? 

 Or should we re-draw selection after update?

 - At the moment on the browser window resize the graphic is not autoupdated,

 we probably should force update.

Graph

=====

 - With small graph area (and big left part), the time labels are starting

 to overlap at some point (Andreas)

 - After zooming by mouse, when changing to the secondary window or info tab,

 the "Invalid WINDWO + is specified" returne (Andreas)

 - Prevent complete shadowing (filling) of screen with a single chart in the 

 multiaxis mode. Try to find such axes and fix the problem by stacking them 

 vertically and increasing axis range.

 - Logarithmic axes has problems with drawing 0 values, - where should we

 start?
