By the convention of errors, there is supposed to be a space between the code and the name.
While looking at some lua stuff I noticed that interpreter errors were not adding the space,
so some clients will try to map the detailed error message into the error.
We have tests that hit this condition, but they were just checking that the string "starts" with ERR.
I updated some other tests with similar incorrect string checking. This isn't complete though, as
there are other ways we check for ERR I didn't fix.
Produces some fun output like:
```
# Errorstats
errorstat_ERR:count=1
errorstat_ERRuser_script_1_:count=1
```
Consider the following example:
1. geoadd k1 -0.15307903289794921875 85 n1 0.3515625 85.00019260486917005437 n2.
2. geodist k1 n1 n2 returns "4891.9380"
3. but GEORADIUSBYMEMBER k1 n1 4891.94 m only returns n1.
n2 is in the boundingbox but out of search areas.So we let search areas contain boundingbox to get n2.

With an empty src key, we need to deal with two situations:
1. non-STORE: We should return emptyarray.
2. STORE: Try to delete the store key and return 0.
This applies to both GEOSEARCHSTORE (new to v6.2), and
also GEORADIUS STORE (which was broken since forever)
This pr try to fix#9261. i.e. both STORE variants would have behaved
like the non-STORE variants when the source key was missing,
returning an empty array and not deleting the destination key,
instead of returning 0, and deleting the destination key.
Also add more tests for some commands.
- GEORADIUS: wrong type src key, non existing src key, empty search,
store with non existing src key, store with empty search
- GEORADIUSBYMEMBER: wrong type src key, non existing src key,
non existing member, store with non existing src key
- GEOSEARCH: wrong type src key, non existing src key, empty search,
frommember with non existing member
- GEOSEARCHSTORE: wrong type key, non existing src key,
fromlonlat with empty search, frommember with non existing member

This commit revives the improves the ability to run the test suite against
external servers, instead of launching and managing `redis-server` processes as
part of the test fixture.
This capability existed in the past, using the `--host` and `--port` options.
However, it was quite limited and mostly useful when running a specific tests.
Attempting to run larger chunks of the test suite experienced many issues:
* Many tests depend on being able to start and control `redis-server` themselves,
and there's no clear distinction between external server compatible and other
tests.
* Cluster mode is not supported (resulting with `CROSSSLOT` errors).
This PR cleans up many things and makes it possible to run the entire test suite
against an external server. It also provides more fine grained controls to
handle cases where the external server supports a subset of the Redis commands,
limited number of databases, cluster mode, etc.
The tests directory now contains a `README.md` file that describes how this
works.
This commit also includes additional cleanups and fixes:
* Tests can now be tagged.
* Tag-based selection is now unified across `start_server`, `tags` and `test`.
* More information is provided about skipped or ignored tests.
* Repeated patterns in tests have been extracted to common procedures, both at a
global level and on a per-test file basis.
* Cleaned up some cases where test setup was based on a previous test executing
(a major anti-pattern that repeats itself in many places).
* Cleaned up some cases where test teardown was not part of a test (in the
future we should have dedicated teardown code that executes even when tests
fail).
* Fixed some tests that were flaky running on external servers.
Fix errors of GEOSEARCH bybox search due to:
1. projection of the box to a trapezoid (when the meter box is converted to long / lat it's no longer a box).
2. width and height mismatch
Changes:
- New GEOSEARCH point in rectangle algorithm
- Fix GEOSEARCH bybox width and height mismatch bug
- Add GEOSEARCH bybox testing to the existing "GEOADD + GEORANGE randomized test"
- Add new fuzzy test to stress test the bybox corners and edges
- Add some tests for edge cases of the bybox algorithm

Add commands to query geospatial data with bounding box.
Two new commands that replace the existing 4 GEORADIUS* commands.
GEOSEARCH key [FROMMEMBER member] [FROMLOC long lat] [BYRADIUS radius
unit] [BYBOX width height unit] [WITHCORD] [WITHDIST] [WITHASH] [COUNT
count] [ASC|DESC]
GEOSEARCHSTORE dest_key src_key [FROMMEMBER member] [FROMLOC long lat]
[BYRADIUS radius unit] [BYBOX width height unit] [WITHCORD] [WITHDIST]
[WITHASH] [COUNT count] [ASC|DESC] [STOREDIST]
- Add two types of CIRCULAR_TYPE and RECTANGLE_TYPE to achieve different searches
- Judge whether the point is within the rectangle, refer to:
geohashGetDistanceIfInRectangle
This commit closes issue #3698, at least for now, since the root cause
was not fixed: the bounding box function, for huge radiuses, does not
return a correct bounding box, there are points still within the radius
that are left outside.
So when using GEORADIUS queries with radiuses in the order of 5000 km or
more, it was possible to see, at the edge of the area, certain points
not correctly reported.
Because the bounding box for now was used just as an optimization, and
such huge radiuses are not common, for now the optimization is just
switched off when the radius is near such magnitude.
Three test cases found by the Continuous Integration test were added, so
that we can easily trigger the bug again, both for regression testing
and in order to properly fix it as some point in the future.
The test now uses more diverse radius sizes, especially sizes near or
greater the whole earth surface are used, that are known to trigger edge
cases. Moreover the PRNG seeding was probably resulting into the same
sequence tested over and over again, now seeding unsing the current unix
time in milliseconds.
Related to #3631.
By grepping the continuous integration errors log a number of GEORADIUS
tests failures were detected.
Fortunately when a GEORADIUS failure happens, the test suite logs enough
information in order to reproduce the problem: the PRNG seed,
coordinates and radius of the query.
By reproducing the issues, three different bugs were discovered and
fixed in this commit. This commit also improves the already good
reporting of the fuzzer and adds the failure vectors as regression
tests.
The issues found:
1. We need larger squares around the poles in order to cover the area
requested by the user. There were already checks in order to use a
smaller step (larger squares) but the limit set (+/- 67 degrees) is not
enough in certain edge cases, so 66 is used now.
2. Even near the equator, when the search area center is very near the
edge of the square, the north, south, west or ovest square may not be
able to fully cover the specified radius. Now a test is performed at the
edge of the initial guessed search area, and larger squares are used in
case the test fails.
3. Because of rounding errors between Redis and Tcl, sometimes the test
signaled false positives. This is now addressed.
Whenever possible the original code was improved a bit in other ways. A
debugging example stanza was added in order to make the next debugging
session simpler when the next bug is found.
Georadius works by computing the center + neighbors squares covering all
the area of the specified position and radius. Then a distance filter is
used to remove elements which are actually outside the range.
When a huge radius is used, like 5000 km or more, adjacent neighbors may
collide and be the same, leading to the reporting of the same element
multiple times. This only happens in the edge case of huge radius but is
not ideal.
A robust but slow solution would involve qsorting the range to remove
all the duplicates. However since the collisions are only in adjacent
boxes, for the way they are ordered in the code, it is much faster to
just check if the current box is the same as the previous one processed.
This commit adds a regression test for the bug.
Fixes#2767.
Rationale:
1. The commands look like internals exposed without a real strong use
case.
2. Whatever there is an use case, the client would implement the
commands client side instead of paying RTT just to use a simple to
reimplement library.
3. They add complexity to an otherwise quite straightforward API.
So for now KILLED ;-)
The GIS standard and all the major DBs implementing GIS related
functions take coordinates as x,y that is longitude,latitude.
It was a bad start for Redis to do things differently, so even if this
means that existing users of the Geo module will be required to change
their code, Redis now conforms to the standard.
Usually Redis is very backward compatible, but this is not an exception
to this rule, since this is the first Geo implementation entering the
official Redis source code. It is not wise to try to be backward
compatible with code forks... :-)
Close#2637.
We set random points in the world, pick a random position, and check if
the returned points by Redis match the ones computed by Tcl by brute
forcing all the points using the distance between two points formula.
This approach is sounding since immediately resulted in finding a bug in
the original implementation.
Current todo:
- replace functions in zset.{c,h} with a new unified Redis
zset access API.
Once we get the zset interface fixed, we can squash
relevant commits in this branch and have one nice commit
to merge into unstable.
This commit adds:
- Geo commands
- Tests; runnable with: ./runtest --single unit/geo
- Geo helpers in deps/geohash-int/
- src/geo.{c,h} and src/geojson.{c,h} implementing geo commands
- Updated build configurations to get everything working
- TEMPORARY: src/zset.{c,h} implementing zset score and zset
range reading without writing to client output buffers.
- Modified linkage of one t_zset.c function for use in zset.c
