This adds a log file at /var/log/apk.log. On each run, apk's version
information and the current date & time are written to this file,
followed by any normal apk output.
This commits adds a function for receiving the closet byte unit and the
size in that unit for a given size_t. The function doesn't return a
string since dynamic memory allocation (or a static buffer) would be
required to implement this properly.
Discussion: It might be useful to add a command line flag for disabling
this behaviour in order to retain compatibility with the previous apk
info output format.
- let the apk_print functions deal with the forced print itself. We
avoid that the callbacks need to deal with the force flag. We can
also get rid of the APK_PRINT_PROGRESS_* defines.
- let the reader of --progress-fd decide how often things are updated
rather than having a fixed granularity off 1/100 (percent)
- avoid detect screen size and percent/bar calculations in case the
--no-progress was given
- track satistics for both the ascii bar and percent info and update bar
only if either percent or bar changes. This makes the bar go smoother
when width is wider than 100 chars and it makes the percent counter
go smooth when screen width is less thann 100 chars. It also
simplifies the callbacks as they no longer need to deal with update
granularity.
Instead of the dependency oriented logic, switch to print them
for each package or name needed. Might give a bit more readable
errors now. There's still few corner cases that proper error is
not output, which are cought by the test cases.
