2020-07-22devdraw, libdraw: fix memory leaks by freeing getns() malloced string (#431)Igor Böhm1-2/+5
2020-05-29libdraw: handle larger number of subfontsRuss Cox1-1/+1
2020-05-18devdraw, libdraw: handle keyboard runes > U+FFFFRuss Cox3-2/+17
Runes in Plan 9 were limited to the 16-bit BMP when I drew up the RPC protocol between graphical programs and devdraw a long time ago. Now that they can be 32-bit, use a 32-bit wire encoding too. A new message number to avoid problems with other clients (like 9fans.net/go). Add keyboard shortcut alt : , for U+1F602, face with tears of joy, to test that it all works.
2020-01-14libdraw: send hangup to process when window is lostRuss Cox1-1/+5
This matches the Plan 9 behavior a bit better. Fixes #30.
2020-01-14libdraw: use proper pipe for default font dataRuss Cox1-6/+16
May fix a deadlock / missing font on OpenBSD. Fixes #308.

Should default to building the library, not getsubfont.o.

Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
2019-04-05libdraw,devdraw: fix compatibility with old 16x16 cursor protocol (#217)Fazlul Shahriar2-1/+24
Some libraries that depend on devdraw don't know about 32x32 cursor -- mainly 9fans.net/go/draw.
2018-11-16libdraw: redo default font construction to be hidpi-safeRuss Cox12-497/+372
If $font is not set, the default font is constructed from font data linked into every libdraw binary. That process was different from the usual openfont code, and so it was not hidpi-aware, resulting in very tiny fonts out of the box on hidpi systems, until users set $font. Fix this by using openfont to construct the default font, by recognizing the name *default* when looking for font and subfont file contents. Then all the hidpi scaling applies automatically. As a side effect, the concept of a 'default subfont' is gone, as are display->defaultsubfont, getdefont, and memgetdefont.
2018-11-15libdraw: add Cursor2, a 32x32 high-res cursorRuss Cox6-6/+64
Also add setcursor2, esetcursor2, and draw protocol encoding. Calls to the old setcursor, esetcursor create a 32x32 by pixel doubling when needed.

2017-04-08libdraw: replace hand-rolled realloc, preventing buffer overflow.Ray Lai1-3/+1
The original buffer is f->nsubf*sizeof *subf bytes (oldsize) large. Once it's full, a new buffer of (f->nsubf+DSUBF)*sizeof *subf (newsize) is mallocated. Unfortunately memmove() reads (newsize) bytes from the original (oldsize) buffer, causing a buffer overflow. By switching to realloc(), we don't need to do buffer size calculation, memmoving, and freeing of the original buffer.

2006-11-04In non-blocking recv functions in libmux and libdraw,rsc2-15/+31
distinguish between "cannot receive without blocking" and "EOF on connection". In libmux, do not elect async guys muxers, so that synchronous RPC calls run in the main event loop (e.g., in eresized) do not get stuck. Fixes problem reported by Lu Xuxiao, namely that jpg etc. would spin at 100% cpu usage.
