elmikoalazarev: ping00:02
alazarevelmiko, here00:03
elmikois Vitaly Gridnev in Saratov?00:03
alazarevelmiko, yes00:04
elmikoalazarev: i hate to -1 https://review.openstack.org/#/c/134504/ again, but i feel it's getting kind complicated00:05
*** chlong has joined #openstack-sahara00:05
elmikoalazarev: also, i was reading some of your specs. i like the multi-threaded stuff you are proposing, what's your opinion about migrating to pecan?00:06
alazarevelmiko, actually no options about migrating to pecan... it looks like decision was made on high level, but noone want to spend resources on that00:07
*** tmckay has joined #openstack-sahara00:07
alazarevelmiko, the only project supporting it is ceilometer00:08
elmikoalazarev: ceilometer is the only projet supporting pecan?00:08
alazarevelmiko, yeap00:08
elmikoalazarev: barbican uses it as well00:08
elmikoi thought a few others did too00:09
*** tellesnobrega has quit IRC00:09
alazarevelmiko, oh, didn't take a look to barbican, so may be some other projects00:09
elmikoalazarev: is the issue that pecan is better performance than flask?00:09
alazarevelmiko, but definitely not a majority00:09
alazarevelmiko, the main reason - py3 support00:10
alazarevelmiko, I don't see any other advantages00:10
*** Longgeek has quit IRC00:10
elmikoalazarev: hmm, that doesn't seem like a convincing enough reason. oh well... i've been digging into pecan recently, that's why i'm curious.00:11
*** tellesnobrega has joined #openstack-sahara00:11
alazarevelmiko, there is no way to go to py3 with flask, openstack board doesn't like dead ends00:12
elmikoalazarev: good point00:12
elmikotake care, i'm out00:13

egaffordtmckay: Looking at https://review.openstack.org/#/c/142248/11/sahara/db/sqlalchemy/api.py. I'm not ridiculously familiar with sqlalchemy: at the point at which you're assessing the search_opts kvps, have "%"s already been escaped? That is, if a search string legitimately contains an escaped percentage sign that is not a SQL control character, will this method successfully recognize that that string shouldn't be a LIKE expression?21:22
*** amcrn has joined #openstack-sahara21:27
tmckayegafford, no, it's not handling escapes21:28
egaffordtmckay: Okay, so any % is assumed to be a LIKE? Particularly given that we have been known to store Python format strings in our DB, that seems like it could be unfortunate for perf.21:28
egaffordI can see the argument that as this is just parsing the search string, there's no real need to make it more complex, though. It would take a fairly large cloud to make this a possible problem.21:33
tmckayegafford, I think it's unlikely that a literal '%' will end up in the URL column values for a data source, which is the only place this is being used at present.  But it could be improved.21:35
tmckayhmm21:36
egaffordAh, I'm sorry; I didn't note that this was only being used in data_source_count, and was not used otherwise.21:36
tmckaywell, chars outside ASCII could be encoded that way21:37
tmckayin urls21:37
egaffordTrue; they frequently are.21:37
egaffordBeyond that, the method set (in_filter, like_filter) has a lot of broad applicability, and I wouldn't be surprised if others built on this in the future for other cases.21:38
*** Networkn3rd has quit IRC21:40
tmckayso the problem comes when we use a like filter on a search where the search term includes a literal '%'.  Currently only for counting data sources, and only for one internal call.  So I don't think it's worth holding up the CR, but it may be worth a low priority bug21:42
egaffordI completely agree.21:43
tmckayegafford, feel free to file a bug against it21:43
egaffordtmckay: Cool; I'll file away a note to do so after CR.21:44
tmckaygreat, thanks21:44
egaffordClearly not a huge deal in any event. Thanks tmckay.21:44
