108 chiark-utils (4.1.31) unstable; urgency=medium
110 Bugfixes to programs:
111 * xacpi-simple updated:
112 - Now works with recent kernels by reading /sys/class/power_supply
113 (so is now misnamed, since that may or may not come from acpi).
115 - Copes both with batteries which report charge/current and ones which
117 - Copes with batteries which are not full, charging or discharging
118 (eg, if the system is on a/c but battery charging is suppressed).
119 - Shows red when time remaining is less than 5 minutes (configurable)
120 rather than trying to use "alarm" value from /sys/class/power_supply
121 (which is not very predictable or reliable).
122 - Option -debug produces some debugging output.
123 - In the code, rename pix_... variables to be named after the meaning
124 rather than the default colour.
125 * chiark-backup's /etc/chiark-backup/snap/nosnap is now more careful
126 about rm vs. rmdir of its link/mountpoint/whatever.
128 Documentation and description improvements:
129 * watershed now installs its head doc comment in
130 /usr/share/doc/chiark-utils-bin/watershed.txt.
131 This is apropos of #659989 but is of course not a proper fix.
132 * Mention rcopy-repeatedly in the Description.
134 User-visible packaging improvements:
135 * chiark-backup Suggests chiark-utils-bin, not the nonexistent
136 chiark-cprogs (for `summer').
138 Other packaging and source code improvements:
139 * Provide build-arch and build-indep debian/rules targets.
140 * Fix the type of a callback function passed to scandir, to expect
141 struct dirent**'s rather than void*'s.
142 * Add -Wno-pointer-sign to gcc warning options.
143 * Add ${misc:Depends} to Depends: lines. Causes no change to the .debs.
144 * Switch to git. Move .cvsignores to .gitignore, etc.
