I have seen some other programs do this, and think it's pretty cool. Means
you can test wherever it's deployed, as well as at build time.
My other reason for doing it is less happy. Cabal's handling of test suites
sucks, requiring duplicated info, and even when that's done, it fails to
preprocess hsc files here. Building it in avoids that and avoids having
to explicitly tell cabal to enable test suites, which would then make it
link the test executable every time, which is unnecessarily slow.
This also has the benefit that now "make fast test" does a max speed build
and tests it.
The only thing lost is ./ghci
Speed: make fast used to take 20 seconds here, when rebuilding from
touching Command/Unused.hs. With cabal, it's 29 seconds.
Pity that the library does not provide a function to extract the status
code from the StatusCodeException, so when they had to add a new field, it
breaks every single place that does it.
Various things that don't work on Android are just ifdefed out.
* the webapp (needs template haskell for arm)
* --include and --exclude globbing (needs libpcre, which is not ported;
probably I'll make it use the pure haskell glob library instead)
* annex.diskreserve checking (missing sys/statvfs.h)
* timestamp preservation support (yawn)
* S3
* WebDAV
* XMPP
The resulting 17mb binary has been tested on Android, and it is able to,
at least, print its usage message.
I need to clean up the path to hasktags. Ideally by packaging it in Debian.
Not using ghci's own tags generation because it falls over on pre-compiled
files.
This allows it to use Build.SysConfig to always install the programs
configure detected. Amoung other fixes, this ensures the right uuid
generator and checksum programs are installed.
I also cleaned up the handling of lsof's path; configure now checks for
it in PATH, but falls back to looking for it in sbin directories.
This ensures that the standalone builds will include lsof, and it'll then
be in the runshell PATH, so will work.
This does not deal with manual builds where lsof is not in path, which
will fail at runtime due to the program being missing.
