If a command invocation such as 'daemon' is interrupted, the interrupt
handler asks the node to close. The closing of the node will result in
the command invocation finishing, and possibly returning from main()
before the interrupt handler is done. In particular, the info logging
that a graceful shutdown was completed may never reach reach stdout.
As the whole point of logging "Gracefully shut down." is to give
confidence when debugging that the shutdown was clean, this is
slightly unfortunate.
The interrupt handler needs to be set up in main() instead of Run(),
so that we can defer the closing of the interrupt handler until just
before returning from main, not when Run() returns with a streaming
result reader.
This reverts commit f74e71f965.
The 'Online' flag of the command context does not seem to be set in
any code paths, at least not when running commands such as 'ipfs daemon'
or 'ipfs ping'. The result after f74e71f9 is that we never shutdown
cleanly, as we'll always os.Exit(0) from the interrupt handler.
The os.Exit(0) itself is also dubious, as conceptually the interrupt
handler should ask whatever is stalling to stop stalling, so that
main() can return like normal. Exiting with -1 in error cases where
the interrupt handler is unable to stop the stall is fine, but the
normal case of interrupting cleanly should exit through main().
We now consider debugerrors harmful: we've run into cases where
debugerror.Wrap() hid valuable error information (err == io.EOF?).
I've removed them from the main code, but left them in some tests.
Go errors are lacking, but unfortunately, this isn't the solution.
It is possible that debugerros.New or debugerrors.Errorf should
remain still (i.e. only remove debugerrors.Wrap) but we don't use
these errors often enough to keep.
This commit adds a new set of sharness tests for pinning, and addresses
bugs that were pointed out by said tests.
test/sharness: added more pinning tests
Pinning is currently broken. See issue #1051. This commit introduces
a few more pinning tests. These are by no means exhaustive, but
definitely surface the present problems going on. I believe these
tests are correct, but not sure. Pushing them as failing so that
pinning is fixed in this PR.
make pinning and merkledag.Get take contexts
improve 'add' commands usage of pinning
FIXUP: fix 'pin lists look good'
ipfs-pin-stat simple script to help check pinning
This is a simple shell script to help check pinning.
We ought to strive towards making adding commands this easy.
The http api is great and powerful, but our setup right now
gets in the way. Perhaps we can clean up that area.
updated t0081-repo-pinning
- fixed a couple bugs with the tests
- made it a bit clearer (still a lot going on)
- the remaining tests are correct and highlight a problem with
pinning. Namely, that recursive pinning is buggy. At least:
towards the end of the test, $HASH_DIR4 and $HASH_FILE4 should
be pinned indirectly, but they're not. And thus get gc-ed out.
There may be other problems too.

this more clearly explains that the daemon is listening on the network. it also hints as to how to change the listening ports. this is also related to #874

This allows someone to host a static site by pointing a TXT record at their
content in IPFS, and a CNAME record at an IPFS gateway.
Note that such a setup technically violates RFC1912 (section 2.4; "A CNAME
record is not allowed to coexist with any other data."), but tends to work in
practice.
We may want to consider changing the DNS->IPFS resolution scheme to allow this
scenario to be RFC-compliant (e.g. store the mapping on a well-known subdomain
to allow CNAME records on the domain itself).

fix(cmd/daemon) set node on req context since it expects daemon to be
present when handling commands over the API
@jbenet revenge of the request context redux
