|
||
|
|
- in the language dialog box, "allow set! on undefined" is ignored
|
||
|
|
|
||
|
|
- check syntax doesn't traverse unit or class expressions
|
||
|
|
|
||
|
|
- check syntax: identifiers with newlines in them have their arrows
|
||
|
|
start from funny places.
|
||
|
|
|
||
|
|
- eval'ing images in drscheme is broken
|
||
|
|
|
||
|
|
- backup files don't preserve file permissions

|
- replace can't replace with an empty string (ie, deleting
|
||
|
|
a word by finding it and replacing it with empty doesn't work)
|
||
|
|
|
||
|
|
- bad url's are not handled smoothly
|
||
|
|
|
||
|
|
- mred:console%'s initialization argument: `close-item?' is being ignored
|
||
|
|
|
||
|
|
- backup files don't preserve permissions
|
||
|
|
|
||
|
|
- the directory line in the common-file-dialogs is confusing
|
||
|
|
|
||
|
|
- embedded snips should be reset on the styles-fixed? ivar
|
||
|
|
|
||
|
|
- "scale" in open-viewport does effect the size
|
||
|
|
of the viewport, but is ignored by at least
|
||
|
|
draw-line into that viewport.
|
||
|
|
|
||
|
|
- you cannot break (read)
|
||
|
|
|
||
|
|
- pathnames should be normalized to early and can cause automouter problems
|
||
|
|
|
||
|
|
- control-l doesn't get the horizontal direction right.
|
||
|
|
|
||
|
|
- editor frames aren't gc'd when modified and search is open

* Windows: place windows neatly for "default" position instead of
|
||
|
|
always placing them at 0, 0
|
||
|
|
|
||
|
|
* X Windows: modal dialogs can still be closed with the Window
|
||
|
|
Manager
|
||
|
|
|
||
|
|
* X Windows and drawing into b & w bitmaps: black and white
|
||
|
|
are reversed when using certain kinds of displays
|
||
|
|
|
||
|
|
* wx:dc%'s draw-arc is undefined when input isn't
|
||
|
|
consistent with a circle
|
||
|
|
|
||
|
|
* wx:key-event% needs a set-position method
|
||
|
|
|
||
|
|
* Windows: set-user-scale with wx:memory-dc% doesn't work right
|
||
|
|
|
||
|
|
* MacOS: busy-cursor state is wrong for new windows when the
|
||
|
|
busy cursor is active
|
||
|
|
|
||
|
|
* pasteboards: printing not yet implemented
|
||
|
|
|
||
|
|
* need to penalize the current thread more for certain primitive
|
||
|
|
operations that can take a long time (e.g., loading a bitmap
|
||
|
|
or saving a file)
|
||
|
|
|
||
|
|
* need range check for dc transfer modes
|
||
|
|
|
||
|
|
* need directory-selection dialog
|
||
|
|
|
||
|
|
* cursor changes to arrow over clickback after hitting it
|
||
|
|
|
||
|
|
* cursor does not change over clickbacks in embedded buffers
|
||
|
|
|
||
|
|
* Keys like KP_end, etc. are not currently accessible
|
||
|
|
|
||
|
|
* doc: [Mr] clarify "owning the caret" with respect to ownership by the parent, etc.
|
||
|
|
|
||
|
|
* doc: [Mr] "only valid when displayed": hyper-link to explanation.
|
||
|
|
|
||
|
|
* Motif: get-file dialog modality is wrong for eventspaces
|
||
|
|
|
||
|
|
* Windows and MacOS: "primitive" dialogs don't get closed by
|
||
|
|
custodian-shutdown-all
|
||
|
|
|
||
|
|
* MacOS: std file dialog and print dialogs block MzScheme threads
|
||
|
|
|
||
|
|
* maliciously overriding set-admin can crash merge-snip and split-snip
|
||
|
|
|
||
|
|
* cut-n-paste within mred but across eventspaces breaks security and
|
||
|
|
filesaving because snip class list is eventspace-specific
|
||
|
|
|
||
|
|
* how does wx:dc% get-size interact with the user scale?
|
||
|
|
|
||
|
|
* the full width for non-wrapped lines need not include the autowrap bitmap
|
||
|
|
|
||
|
|
* should use a guranteed offset for stippling in buffer redraws
|
||
|
|
|
||
|
|
* Xt: out-of-colours - widgets use too much black
|
||
|
|
|
||
|
|
* signature include: unbalanced parens => diverge?
|
||
|
|
|
||
|
|
* drag outisde view => should keep going even if mouse is still
|
||
|
|
|
||
|
|
* hidden files - add a MzScheme predicate?
|
||
|
|
|
||
|
|
* dragging selection shouldn't keep changing the auto-X-selection
|
||
|
|
|
||
|
|
* Xt: busy cursor not shown in the menu bar
|
||
|
|
|
||
|
|
* editor buffers should show a blinking caret
|
||
|
|
|
||
|
|
* Motif: menus don't work with multiple displays
|
||
|
|
|
||
|
|
* Motif: wxDialogBox doesn't obey current display for multiple displays
|
||
|
|
|
||
|
|
* add background colour for buffers?
|
||
|
|
|
||
|
|
* updating bug?: long flash, not on same line, update on focus-in
|
||
|
|
|
||
|
|
* add paragraph styles?
|
||
|
|
|
||
|
|
* need better de-fragmentation of text snips
|
||
|
|
|
||
|
|
* need to show a mystery snip icon when unknown data is loaded from a file

|
"synrule.ss" is missing `let-syntax' and `letrec-syntax'
|
||
|
|
|
||
|
|
`unit/sig' incorrectly handles syntax where defintions in the unit
|
||
|
|
shadow syntactic forms
|
||
|
|
|
||
|
|
Under HP/UX, image --restore doesn't work
|
||
|
|
|
||
|
|
On Alpha machines, floating-point overflow is not handled properly
|
||
|
|
(so +inf.0, -inf.0, and +nan.0 are messed up)
|
||
|
|
|
||
|
|
Under MacOS, `tcp-listen' does not work reliably
|
||
|
|
|
||
|
|
Under MacOS, in the standalone MzScheme application, a blocking read
|
||
|
|
from stdin blocks all MzScheme threads
|
||
|
|
|
||
|
|
Under Unix, (execute s) is just (exit (if (system s) 0 -1)), while
|
||
|
|
execute* replaces the current process like it is supposed to
|
||
|
|
|
||
|
|
Under Windows, the `system' procedure blocks all MzScheme threads
|
||
|
|
(`system*' works correctly)
|
||
|
|
|
||
|
|
Under AIX, write to tcp output port blocks when the low-level
|
||
|
|
buffer is full
|
||
|
|
|
||
|
|
Under FreeBSD, if the descripters limit is greater than 256, then
|
||
|
|
it is automatically reduced to 256 within MzScheme/MrEd/DrScheme
|
||
|
|
|
||
|
|
Still to be added to support R5RS:
|
||
|
|
(scheme-report-environment n)
|
||
|
|
(null-environment n)
|
||
|
|
(interaction-environment)
|
||
|
|
(port? v)
