Turns out that 7be690f326 broke the
test suite on the i386ancient builder. There, git show-ref --verify HEAD
fails with "'HEAD' - not a valid ref". Apparently git 2.1.4 didn't
support that.
headExists works there and does the same thing.
This code was already AGPL, except for the bit split out
to Utility/MD5.hs in commit 426053cb6c.
That commit accidentially updated the license of this file from AGPL
to GPL.
Thanks to Sean Whitton for spotting this.
Systems such as Debian that have overridden the default fpath will need to
set ZSH_COMPLETIONS_PATH.
I feel that Debian is causing unncessary complexity by making this change,
and have filed a bug report about it.
This also means that when git-annex is installed with PREFIX=/usr/local
it will use /usr/local/share/zsh/site-functions which works with probably
all versions of zsh.
Its repeated opening and writing to the sqlite database somehow caused
inode cache information to occasionally be lost.
This loses code coverage, since running git-annex as a child process
prevents tracking what parts of the code are exercised. I have not looked
at the code coverage in a long time. It would probably be possible to
collect code coverage for the child procesess and merge it together.
Prompted by the test suite on windows failing to with "export foo failed"
and no information about what went wrong.
Note that only storeExportWithContentIdentifier has been converted.
storeExport still returns a Bool and so exceptions may be hidden.
However, storeExportWithContentIdentifier has many more failure modes,
since it needs to avoid overwriting modified files. So it's more
important it have better error display.
