Large refactor that more closely aligns the codebase to the kj async
style, more clearly exposes an interface for functional testing and
removes cruft. There is a slight increase in coupling between the
Laminar and Http/Rpc classes, but this was always an issue, just until
now more obscured by the arbitrary pure virtual LaminarInterface class
(which has been removed in this change) and the previous lumping
together of all the async stuff in the Server class (which is now
more spread around the code according to function).
This change replaces the use of Websockets with Server Side Events
(SSE). They are simpler and more suitable for the publish-style messages
used by Laminar, and typically require less configuration of the
reverse proxy HTTP server.
Use of gmock is also removed, which eases testing in certain envs.
Resolves#90.
On systems such as Alpine Linux (with busybox) and Adelie Linux (with
coreutils), the shell core utilities such as pwd, true, false, env, and
yes are all symlinks to a single binary. This single binary relies on
the name of the symlink to determine which command ("applet" in busybox
parlance) to execute. Therefore creating symlinks to these symlinks will
not work since the single binary will only see the top-level symlink and
thus think it is an invalid command.
Instead, generate executable shell scripts that exec into the desired
command. This also allows $PATH based resolution to occur instead of
hard-coding the command paths.
See also issue #94.
Lose the boost dependency since recent versions of capnproto's kj
also provide a nice filesystem library. Take the opportunity to
refactor the Run object to become more than POD and to encapsulate
some of the functionality that was done in the Laminar class
Part of #49 refactor
- regressions and recoveries: list of jobs whose run status changed,
ordered first by currently failing jobs, secondly by count of jobs
since the status change, descending for currently failing jobs and
ascending for currently passing jobs
- low pass rates: list of the jobs with the worst pass rates calculated
over all time
- run time changes: jobs with the largest changes in build time. This
is calculated as the difference between the range and the standard
deviation over the past 10 runs.
- average run time distribution: shows the number of jobs in the
system divided into buckets based on their average runtime
This is a refactor that more cleanly uses the kj framework for handling
processes spawned by Runs. This obviates the workaround introduced back in
ff42dae7cc, and incidentally now requires c++14.
Part of #49 refactor
The old implementation slurped the whole artefact into memory, and
did not ensure it remained allocated beyond the first call to write().
The new implementation uses mmap and ensures the mapping lasts until
the file has been delivered
Fixes a crash that happens on g++ 6.3 under debian but not
g++ 7.2.1 under arch. Instead of trying to move kj::AsyncIoStream
between each promise handler, just extract and use the raw
pointer and let attach() clean up the Own<> at the end
Read or writes to bad file descriptors threw exceptions, just log
this instead. Also make sure that LaminarClients are removed from
the list of clients when a connection is aggressively dropped, and
add test
