8d1022b1ac Fix: Explicitely use Itertools::flatten()
As of rustc 1.26, the `flatten()` method on iterators is preserved by
the rust standard library.
This could cause this code to hard-error some time in the future with
the `flatten()` function actually implemented by the standard library.

Hence we move to use the `Itertools::flatten()` function here
explicitely.

2f0a557068 Fix for passing Arc<_> to store interface instead of Box<_> 2018-05-01 21:08:57 +02:00
42e2f18fb3 Pass around Arc<FileAbstraction> internally
Because the iterators need to be able to check whether the file exists
_in the backend_ (not on disk, but in the backend, because of in-memory
test for example), we need to be able to pass the backend to the
iterator intermediate type.

This patch implements this. It does so by changing the internal backend
member of the store from `Box<FileAbstraction>` to
`Arc<FileAbstraction>`, which gives us the ability to clone the
reference to the backend easily without needing to rely on lifetimes
here, because of the Arc.

Also, less boxes are always good.

d08c27e623 Rewrite StoreIdIterator extensions
This patch reimplements the iterator extensions.

As we iterate (in StoreIdIterator) over Result<StoreId> now anyways, we
don't need the extensions for Result iterators anymore.

This patch rewrites the extensions to be more simple in every way and
generic over the error type in the iterator.
All the errors have to do is implement From<StoreError>, which is what
they do when linking the generated error types with error_chain to the
libimagstore error types.

a2ff298e67 Rewrite Store::entries()
This patch rewrites the Store::entries() function to not be collecting
the iterator.

It therefore introduces a new, internal, iterator type which creates the
StoreId objects from the pathes the PathIterator yields internally.

With this patch, the Store iterator interface changes, as the iterators
now yield `Result<StoreId, StoreError>` instead of `StoreId`.
This is necessary, as the internal conversion errors shouldn't be
hidden.

Of course, the iterator types (like the StoreGetIterator and so on)
should hold a Result<StoreId> internally as well, and also yield
appropritely. This was changed in this commit, too.

860e47a256 Add functionality to flush the internal cache
Before we had the problem that when iterating over _a lot_ (like 5k)
entries and also fetching them, at some point the OS would return with
"Too many files open".

That is because the store internally caches a lot.

With this change, the Store gets an API to query how big the cache is,
how much the cache can currently hold and (and that's the main thing in
this patch) to flush the cache to disk.

A function to simply ask the store whether its cache should be flushed
(which would us require to ask the OS how many files we can open...
which would be possible with `libc::getrlimit`) does not yet exist,
though, but could be added easily if desired.

d7cfab797f Revert "Implement pipe magic in libimagrt"
This reverts commit ce0bd9298a.

Pipe magic is removed with this patch.

We remove pipe magic because its implementation in libimagstore is too
complicated and the benefits are too small.
Having this functionality would be really nice, but the cost-benefit
ratio would still be too high.
The implementation in the store would require a rewrite of the internal
caching functionality in the store, plus some functionality to serialize
and deserialize the cache. This is theoretically possible, but as the
store only knows about "StoreEntry" objects, and only the backend knows
of "Entry" (which would be simply de/serializeable), the complexity
increases a _lot_.

Hence, we drop this feature-idea here.

Maybe, at some later point, this functionality will be in imag. The
history of development of this feature is in the history, we just don't
have it merged.

Implement pipe magic in libimagrt
2018-03-10 16:20:36 +01:00
ce0bd9298a Implement pipe magic in libimagrt
When we merged the changes in libimagrt so that it automatically detects
whether stdin/stdout is a TTY and provides the user with stderr in case
stdout is not a TTY, we forgot that things like

    imag foo | grep bar

becomes impossible with that, because imag detects that stdout is not a
tty and automatically uses stderr for output.

But in this case, we don't want that. The output has to be stdout in
this case.

With this change, we have a flag in the runtime ("--pipe-magic" or "-P",
globally available) which turns on "pipe magic".

The expected behaviour is the following, if "-P" is passed:

* If stdout is a TTY, we print to stdout
* If stdout is not a TTY, we print to stderr
* If stdin is not a TTY, we do not provide it

If "-P" is not passed, we allow the user of libimagrt to use stdin for
interactive stuff (the interactive stuff is not yet implemented).

da408b9e67 This fixes the file parsing (again)
Unfortunately, our latest fix to file parsing did not solve all issues.
So we have to fix it _again_.

The problem was the `std::str::Lines` iterator, which apparently fails
this:

    assert_eq!(1, "".lines().count());

as an empty line seems not to be a line.

Because of that, when reading a file with an empty line at its bottom
got stripped off that line.

This patch removes the use of the `lines()` iterator and uses
`split("\n")` instead. This only works on Unix operating systems, but as
we only target unix operating systems with imag, this is not considered
an issue right now.

This patch also adds extensive tests on multiple levels in the
`libimagstore` implementation:

* On the parsing level, for the function which implements the parsing
* On the filesystem abstraction levels
* On the `Store` levels

to make sure that everything is parsed correctly.

19e9dfe33c Implement proxy object where runtime configures output
This is another approach for providing access to stdin/out/err via
libimagrt::runtime::Runtime.

The Runtime object does configure which output gets returned (stdout if
stdout is a tty, else stderr).

With this we can change libimagrt to read/write the store from/to
stdin/stdout without the user noticing that she does not write to stdout
but stderr.
Reading from stdin is not possible then, though.

c18c0bbbe4 Provide stdin/out/err resources via Runtime object
This way we can control whether "out" output goes to stdout or stderr
without the user of the functionality knowing.

This is useful for later when we use libimagrt to automatically
read and write the store from and to stdout/in depending on whether we
are talking to a TTY or a pipe.

The regex approach was broken. If the following _content_ was provided
in the entry:

    bar

The regex approach parsed the header until the "---" in the content.
This is, of course, not the way to do that.

Now, the parsing is implemented by hand. Should be faster as well,
though I don't care about this.

This fixes a severe bug.
