We shouldn't attempt to reap a process again after it's been
reaped asynchronously in the SIGCHLD handler. Noticed while
working on changes to get lei/store to use checkpointing.
|
|
There are still some places where on_destroy isn't suitable,
This gets rid of getpid() calls in most of those cases to
reduce syscall costs and cleanup syscall trace output.
|
|
Reset gets called on END{} anyways to workaround DBI lifetime
problems, so there's no need to call it near exit. We can't
replace calls to POSIX::_exit with `exit' to force END{} to
run just yet, as there are still some lingering destruction
ordering problems on newer DBI and or Perls.

While the {inflight} array should be tied to the IO object even
more tightly, that's not an easy task with our current code. So
take some small steps by introducing a gcf_inflight helper to
validate the ownership of the process and to drain the inflight
array via the awaitpid callback.
This hopefully fix problems with t/lei-q-save.t (still) hanging
occasionally on v2 outputs since git->cleanup/->DESTROY was getting
called in v2 shard workers.

The long-term plan is to share non-blocking read buffering logic
with HTTP/NNTP/IMAP/POP3 and also XapClient.
|

Avoid mixing autodie use in different scopes since it's likely
to cause problems like it did in Gcf2. While none of these
fix known problems with test cases, it's likely worthwhile to
avoid it anyways to avoid future surprises.
For Process::IO, we'll add some additional tests in t/io.t
to ensure we don't get unintended exceptions for try_cat.

read_all can be expanded to support FIFOs/pipes/sockets where
read-until-EOF behavior is desired. We can also rely on
wantarray to support splitting on EOL markers, but it's
hard-coded to support only `$/ eq "\n"' since (AFAIK)
it's the only way we use the wantarray form `readline'.

The IO package seems like a better home for I/O subs than the
Git package. We lose the 60 second read timeout for `git
cat-file --batch-*' processes since it's probably not necessary
given how reliable the code has proven and things would fall
over hard in other ways if the storage device were completely
hosed.

This is pretty convenient way to create files for diff
generation in both WWW and lei. The test suite should also be
able to take advantage of it.

This fixes two major problems with the use of tie for filehandles:
* no way to do fcntl, stat, etc. calls directly on the tied handle,
forcing callers to use the `tied' perlop to access the underlying
IO::Handle
* needing separate classes to handle blocking and non-blocking I/O
As a result, Git->cleanup_if_unlinked, InputPipe->consume,
and Qspawn->_yield_start have fewer bizzare bits and we
can call `$io->blocking(0)' directly instead of
`(tied *$io)->{fh}->blocking(0)'
Having a PublicInbox::IO class will also allow us to support
custom read buffering which allows inspecting the current state.
