X neo/storage: Open backends by raw string, not URL · 4000df14

Kirill Smelkov authored Mar 27, 2018

For both current backends (SQLite and fs1) there is currently a problem
of working with UTF-8 filenames if opening is handled via urls. For
example if backend string is

	sqlite://neo.sqlite·P1-1

after parsing as URL and further reassembled as string it will be

	neo.sqlite%C2%B7P1-1

with then errors like

	neo.sqlite%C2%B7P1-1: open: unable to open database file

showing.

Since storage backends primarily work with local files it makes sense
not to play raw url reassembly games and just pass raw strings to
backends for open.

SQLite uri processing is still possible, via e.g.

	sqlite://file:filepath?param=value,...

See

	https://www.sqlite.org/c3ref/open.html	and
	https://www.sqlite.org/uri.html

for details.

X tcpu: Don't depend on running tests with cwd = .../go/neo/t/ · cf1f7c24

Kirill Smelkov authored Mar 26, 2018

Previously when the code was trying to load testdata/ files with
different CWD it was failing with something like

	testdata/zlib/wczdata: no such file or directory.

Fix it by constructing testdata path relative to __file__ of
corresponding source.

X neotest/info-local: Fix disk display in presence of bind-mounts · d35a2fdf

Kirill Smelkov authored Mar 26, 2018

When source device is mounted multiple times, findmnt reports it e.g.
this way:

	|-/mnt/SLAPOS                         /dev/md2     ext4       rw,relatime,stripe=256,data=ordered
	|-/srv/slapgrid                       /dev/md2[/srv/slapgrid]
	                                                   ext4       rw,relatime,stripe=256,data=ordered
	|-/opt/slapgrid                       /dev/md2[/opt/slapgrid]
	                                                   ext4       rw,relatime,stripe=256,data=ordered
	`-/opt/slapos                         /dev/md2[/opt/slapos]
	                                                   ext4       rw,relatime,stripe=256,data=ordered

and then it breaks:

Fix it by telling findmnt to not include '[/dir]' (-v option).

While we are here also add -u which means "Do not truncate text in columns"
which is also good to have on a safe side.

X go/zodb/zeo: Add support for protocols preceding ZEO5 · 60c4ddbe

Kirill Smelkov authored Mar 26, 2018

In particular try to support ZEO4:

- during handshake we now first wait for remote server to announce its
  preferred protocol, and only then send the version we select to use.
  This is the procedure original ZEO server-client do.

- teach rpc.call to decode exceptions not only for how ZEO5 encodes them
  (marking via 2 flag in "async" field), but also on how ZEO4 and
  earlier encode them: via replying with (exc_type, exc_inst) and
  expecting client to dynamically check exc_type is a subtype of
  Exception.

- handle other protocol differences - e.g. ZEO5 returns last_tid on
  register(), while earlier versions return nothing there.

Similarly to deco, neo1 and rio, neo/go/sqlite is speed-up a bit. And
everything else close to noise.

Compared to zwrk@1s it helps but only a very tiny tiny bit: Besides
everything else that might be noise the improvements are:

X rio: localhost timings, Cenabled, zwrk@1s · 31d87ace

Kirill Smelkov authored Mar 09, 2018

Remeasure with the same sattings as previous rio localhost with C-enabled (31dc070d):

Like on neo1 & z6001 data is moreorless the same.

the pystone/s change is nose as pystone/s for C-enabled case was 146k on
prev-prev run (see 31dc070d).

Compared to zwrk@1 it helps, but only a tiny bit, and the timings are
still noisy:

The help is much less compared to the signidican speedup with Cstates
disabled (65de70b8).

The next commit will add remeasurements with C-states disabled.

X z6001: localhost timings, Cenabled, zwrk@1s · 7f785235

Kirill Smelkov authored Mar 09, 2018

Remeasure with the same sattings as previous z6001 localhost with C-enabled (850bfb9d):

Like on neo1 the data is more or less the same and in particular timings
for either sql backend or python client or even neo/go vs go client are noisy.

X neo1: localhost timings, C > C1 disabled, zwrk@1s · 23f8d82e

Kirill Smelkov authored Mar 09, 2018

Comparing to Cenalbled run, even when there each zwrk was run for 10s,
similarly to previous measure with Cstates disabled (f40c8b4b) it shows
clear improvement:

not to mention that zhash.{py,go}, for which runtime was not changed,
are also improved like it was in f40c8b4b, thus confirming timings from
there:

X neo1: localhost timings, Cenabled, zwrk was running for 10s at each iteration · 5db60f7e

Kirill Smelkov authored Mar 09, 2018

Compared to zwrk@1s (previous commit) the changes are in within, or
close to be in within, noise and in particular it does not help for
-zwrk.go timings like it did with Cstates disabled (f40c8b4b).

X neo1: localhost timings, Cenabled, zwrk was running for 1s at each iteration · 4cbd62f7

Kirill Smelkov authored Mar 09, 2018

Remeasure with same settings as previous neo1 localhost with C-enabled (9644774a):

The data is more or less the same and in particular timings for either
sql backend or python client are noisy.
