* 3065 - Mu language definition for Exuberant CtagsKartik K. Agaram2016-06-241-0/+8
| | | | | | | | | | Thanks Stephen Malina for the suggestion. I don't yet know how to include comments in the .ctagsrc file, so I'll include them here for now: To use this file, symlink or append exuberant-ctags-rc to your ~/.ctagsrc.

* 3054 - keep cursor stable on resize in sandbox/Kartik K. Agaram2016-06-127-29/+112
| | | | This ports commits 3052 and 3053 from the edit/ app.
* 3053 - keep cursor stable on resizeKartik K. Agaram2016-06-121-1/+85
| | | | | As much as possible; if the cursor moves off screen, it still resets to top of screen.
* 3052 - make edit/ render functions higher-orderKartik K. Agaram2016-06-128-44/+48
| | | | | | This required the fix of 3051 to first-class recipe support, and will next enable us to keep the cursor from moving in response to resize events.

* 3047 - fix another hole in refcount managementKartik K. Agaram2016-06-111-26/+56
| | | | | | This wouldn't have failed silently; I have that fig leaf. If someone had tried to copy an exclusive container containing an exclusive container containing an address Mu would have crashed on them.

| | | | Thanks Caleb Couch for finding this.
* 3038 - track down a long-standing bugKartik K. Agaram2016-06-082-50/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some rare situations the editor would join a line with the next when it should simply wrap to the next screen row. Thanks Caleb and Ella Couch for finally running into a situation that was easy to reproduce. The scenario diffs are misleading on this commit. I had to: a) delete the obsolete 'editor-wraps-cursor-after-inserting-characters' because it was written back when a line just large enough to fit in a single line would not wrap: | | <-- screen boundary abcde These days it will wrap after making room for the wrap indicator: | | <-- screen boundary abcd↩ e b) rename editor-wraps-cursor-after-inserting-characters-2 to editor-wraps-cursor-after-inserting-characters-in-middle-of-line c) create a new scenario demonstrating the bug: editor-wraps-cursor-after-inserting-characters-at-end-of-line
* 3037Kartik K. Agaram2016-06-071-8/+12
| | | | | | By disabling lookups on the product of 'create-array', I'd messed it up so we were treating the product as a raw address and ignoring default-space. Just remove that exception.
* 3036Kartik K. Agaram2016-06-061-1/+27
| | | | | | | Drastically streamlined floating-point overflow/underflow detection. For some reason I can't find a way to actually handle SIGFPE traps; they have to segfault the program.
* 3035Kartik K. Agaram2016-06-061-33/+0
| | | | | | | | I'd included handling for SIGFPE on faith but I'm not actually able to see it triggering. Drop it until we can at least test it manually. In general, floating-point is horrendous: https://hal.archives-ouvertes.fr/hal-00576641v1/document. Neither types nor tests will help deal with it.

* 3031 - better integer overflow protectionKartik K. Agaram2016-06-021-1/+68
| | | | | | | | | | | | | | | | | | | | | | This improves on commit 3026; it turns out you need to manually handle the traps generated by -ftrapv. https://gist.github.com/mastbaum/1004768 Signal handling is based on https://spin.atomicobject.com/2013/01/13/exceptions-stack-traces-c. Various combinations of platform+compiler seem to work very differently: gcc everywhere seems to have extremely threadbare ftrapv support Clang + OSX generates SIGILL. Clang + Linux is advertised to generate SIGABRT, so I handle that out of an excess of caution. However, in my experience it seems to kill the program (sometimes segfaulting) even without any signal handlers installed. In the process, I realized that all my current builds are using Clang, so I added one little test on CI to use g++ in commit 3029.

* 3026 - integer overflow protectionKartik K. Agaram2016-06-022-3/+3
| | | | | | | How did I not know about -ftrapv for so long?! Found while reading Memarian et al, "Into the depths of C: Elaborating the de facto standards". http://www.cl.cam.ac.uk/~pes20/cerberus/pldi16.pdf
* 3025 - fix a minor annoyance in edit/Kartik K. Agaram2016-05-292-6/+158
| | | | | When I floor the down-arrow too much, don't scroll unnecessarily off the bottom of the screen. But *do* scroll if there's errors to show.

* 3020 - names in chessboard testsKartik K. Agaram2016-05-263-96/+118
| | | | | | | | Extremely ugly change. Also ended up fixing some places where I was mixing up sources and sinks. But I'm not going to bother updating edit/ and sandbox/ apps. Just too many scenarios to clean up.
