648.1.1	Extract the funcs relating to shutting down ctwm ('restart' ... Extract the funcs relating to shutting down ctwm ('restart' is a kind of shutdown) into their own file.	Matthew Fuller	6 years ago
648	Cleanup/adjust how signal handlers work. Cleanup/adjust how signal handlers work. Move them off into their own file to cut down on the stuff in ctwm_main.c. Clear out handlers that haven't been compiled in in ages, and ones that can't really work well. Remove non-async-signal-safe calls and change the main ones around to just setting a general flag. Have a more general "signal action needed" flag for the event loop to trigger and call over.	Matthew Fuller	6 years ago
647	Fix some possible leaks/use-after-free in InsertRGBColormap(... Fix some possible leaks/use-after-free in InsertRGBColormap(). From twm. git revs 4512f268c689db62b46c88e813935c66eda14742 and 777236e942ae85bcacfdc2e086944a42cfed5b45.

646	Do a bunch of reworking to allow large parts of the startup ... Do a bunch of reworking to allow large parts of the startup sequence to sorta-work even without an actual X connection. This aims at a visible purpose of being able to run --cfgchk even without an X server to connect to. Some code is moved to after the config parsing to allow that (including actually trying to take over the screen). Various about-the-server info we need during config processing is faked if necessary. Some of the code invoked by the config parsing was directly interacting with the X server in ways that could be easily delayed until afterward. Other parts couldn't be, but could be conditionalized to stub themselves out if there were no connection, in ways that probably won't affect anything for those cases since it's not trying to _do_ anything with X in that situation. A further effect of this is that --cfgchk now supports multiple screens with their possibly different config files as well. The tools/try_all_opts.pl script for trying the build options now empties out the $DISPLAY env, so running the test suite through it won't try to connect to your real server for better isolation. Because some of the backend actions differ if there's no connection, it's difficult to guarantee that --cfgchk without $DISPLAY will actually catch all the problems it would otherwise. Things with colors and colormaps are particularly likely spots to run into its limits here. Most of the checks are still valid, however. There is a non-zero chance that there are additional landmines in config checking codepaths I didn't find in inspection and testing, that will assume a valid connection, and segfault in a no-$DISPLAY --cfgchk. Normal operation wouldn't hit them though, so their impact will be limited to annoying a dev when it happens (which is good, since that'll inspire the dev to go fix it ;).	Matthew Fuller	6 years ago
645	Update libs-needed hints in README, since randr is on by def... Update libs-needed hints in README, since randr is on by default now.	Matthew Fuller	6 years ago
644	Merge RANDR and Layout support. Merge RANDR and Layout support. This adjusts internal data structures defining our display layout to be more flexible. When build with RANDR support (default) and the X server supports the extension, the structures are built with knowledge of the invididual monitors composing the desktop and how they're laid out. The various zoom'ing functions now zoom just on the monitor they're on; .x*zoom functions will zoom across the entire Screen. This makes multi-monitor setups work much more fluidly, especially when they're of differing resolutions or otherwise don't add up to an even rectangular output.	Matthew Fuller	6 years ago
643	Make sure we generate full HTML files, not just fragments, f... Make sure we generate full HTML files, not just fragments, for these outputs.	Matthew Fuller	6 years ago
642	Comment, refactor, and lightly rework the startup process, p... Comment, refactor, and lightly rework the startup process, particularly the per-Screen handling loop. More initialization is moved into the Init function which now also handles allocation etc. Other initialization steps are better documented, including their cross-relationships and ordering requirements. Variables are moved to smaller and in some cases artificial scopes for readability. No visible changes expected.	Matthew Fuller	6 years ago
641	Rejigger finding and starting parsing of the config file. Rejigger finding and starting parsing of the config file. This splits the "go through our list of possible rc file locations" step further out from the "[try to] parse a file" step, giving us a function that directly does what you ask it it as well as the one wrapping up guessing things to try. It also allows rewriting the logic of tring possible locations into something straightforward, instead of the magic-side-effect-riddled pseudo-loop it previously used.	Matthew Fuller	6 years ago
640	List the ctwmlib archive before the shared libs in linking t... List the ctwmlib archive before the shared libs in linking the ctwm binary, and leave a comment about why we need to.	Matthew Fuller	6 years ago
639	Leave a comment about why we often have to pull in ${CTWMLIB... Leave a comment about why we often have to pull in ${CTWMLIBS} on test progs, to answer the question of why we sometimes do and sometimes don't, and why we're setup to do it by default even when it's not needed.	Matthew Fuller	6 years ago
