You should parse the date/time part of the value with
time.strptime(timestr, '%Y%m%d%H%M%S') instead of doing it
manually,
that way you'll get most of the validation for free.
Yes but it gives a crappy error message, just saying that some
data is
left over not what is wrong.
IMHO having a separate error message for every field in the time
string
(like you do in the patch) is an overkill, simple invalid time
and/or
unknown time format should suffice (we don't have errors like
invalid
3rd octet for IP adresses either).
Well, the work is done, hard to go back on a better error message.
Also, it would be nice to be able to enter the value in more
user-friendly format (e.g. 2011-12-14 13:01:25 +0100) and
normalize
that to LDAP generalized time.
When dealing with time there are so many ways to input and
display
the
same values this becomes difficult.
I'd expect that the times for these two attributes will be
relatively
simple and I somehow doubt users are going to want seconds, leap
seconds
or fractions, but we'll need to consider how to do it for future
consistency (otherwise we could have a case where time is
entered in
one
format for some attributes and another for others).
If we input in a nice way we need to output in the same way.
We could make the preferred input/output time format
user-configurable,
defaulting to current locale time format. This format would be
used
for
output. For input, we could go over a list of formats (first the
user-configured format, then current locale format, then a
handful of
standard formats like -MM-DD HH:MM:SS) and use the first
format
that can be successfully used to parse the time string.
See how far you get into the rabbit hole with even this simple
format?
I don't mind, as long as it is the right thing to do (IMHO) :)
Anyway, I think this could be done on the client side, so we might
use
your patch without changes. However, I would prefer if the parameter
class was more generic, so we could use it (hypothetically) to store
time in some other way than LDAP generalized time attribute (at
least
name it DateTime please).
Ok, I'm fine with that.
Thanks.
The LDAP GeneralizedTime needs to be either in GMT or include a
differential. This gets us into the territory where the client
could be
in a different timezone than the server which leads us to why we
dropped
AccessTime in the first place.
Speaking of time zones, the differential alone is not a sufficient
time
zone description, as it doesn't account for DST. Is there a way to
store
time in LDAP with full time zone name (just in case it's needed
sometime
in future)?
There is no way to store DST in LDAP (probably for good reason).
Oddly
enough the older LDAP v3 RFC (2252) strongly recommends using only
GMT
but the RFC that obsoletes it (4517) does not include this.
Thanks for the info.
So I'd like the user to supply the
timezone themselves so I don't have to guess (wrongly) and let them
worry about differing timezones.
We don't have to guess, IIRC there is a way to get the local
timezone
differential in both Python and JavaScript, so the client could
supply
it automatically if necessary.
I was thinking more about non-IPA clients (like sudo and notBefore).
I think this can still be done at least in CLI, but it could be

You should parse the date/time part of the value with

Yes but it gives a crappy error message, just saying that

IMHO having a separate error message for every field in the
time
string
(like you do in the patch) is an overkill, simple invalid
time
and/or
unknown time format should suffice (we don't have errors
like
invalid
3rd octet for IP adresses either).
Well, the work is done, hard to go back on a better error
message.
Also, it would be nice to be able to enter the value in more
user-friendly format (e.g. 2011-12-14 13:01:25 +0100) and
normalize
that to LDAP generalized time.
When dealing with time there are so many ways to input and
display
the
same values this becomes difficult.
I'd expect that the times for these two attributes will be
relatively
simple and I somehow doubt users are going to want
seconds, leap
seconds
or fractions, but we'll need to consider how to do it for
future
consistency (otherwise we could have a case where time is
entered in
one
format for some attributes and another for others).
If we input in a nice way we need to output in the same way.
We could make the preferred input/output time format
user-configurable,
defaulting to current locale time format. This format would be
used
for
output. For input, we could go over a list of formats
(first the
user-configured format, then current locale format, then a
handful of
standard formats like -MM-DD HH:MM:SS) and use the first
format
that can be successfully used to parse the time string.
See how far you get into the rabbit hole with even this simple
format?
I don't mind, as long as it is the right thing to do (IMHO) :)
Anyway, I think this could be done on the client side, so we
might
use
your patch without changes. However, I would prefer if the
parameter
class was more generic, so we could use it (hypothetically) to
store
time in some other way than LDAP generalized time attribute (at
least
name it DateTime please).
Ok, I'm fine with that.
Thanks.
The LDAP GeneralizedTime needs to be either in GMT or include a
differential. This gets us into the territory where the client
could be
in a different timezone than the server which leads us to
why we
dropped
AccessTime in the first place.
Speaking of time zones, the differential alone is not a
sufficient
time
zone description, as it doesn't account for DST. Is there a
way to
store
time in LDAP with full time zone name (just in case it's needed
sometime
in future)?
There is no way to store DST in LDAP (probably for good reason).
Oddly
enough the older LDAP v3 RFC (2252) strongly recommends using
only
GMT
but the RFC that obsoletes it (4517) does not include this.
Thanks for the info.
So I'd like the user to supply the
timezone themselves so I don't have to guess (wrongly) and let
them
worry about differing timezones.
We don't have to guess, IIRC there is a way to get the local
timezone
differential in both Python and JavaScript, so the client could
supply
it automatically if necessary.
I was thinking more about non-IPA clients (like sudo and
notBefore).
I think this can still be done at least in CLI, but it could be
done in
a separate patch.

1. LDAP generalized time allows you to omit minutes from time zone
differential, your code treats such values as invalid
2. IMO a better pattern could be used, such as
u'^([0-9]{2}){5,7}([.,][0-9]+)?([-+]([0-9]{2}){1,2}|Z)$'

4. 20120229000+ has malformed minutes, but the error message
says
Missing operator for differential or malformed time string
5. 20120229+ is valid generalized time, but it causes

Also, it would be nice to be able to enter the value in more user-friendly format (e.g. 2011-12-14 13:01:25 +0100) and normalize that to LDAP generalized time. When dealing with time there are so many ways to input and display the same values this becomes difficult. I'd expect that the times for these two attributes will be relatively simple and I somehow doubt users are going to want seconds, leap seconds or fractions, but we'll need to consider how to do it for future consistency (otherwise we could have a case where time is entered in one format for some attributes and another for others). If we input in a nice way we need to output in the same way. We could make the preferred input/output time format user-configurable, defaulting to current locale time format. This format would be used for output. For input, we could go over a list of formats (first the user-configured format, then current locale format, then a handful of standard formats like -MM-DD HH:MM:SS) and use the first format that can be successfully used to parse the time string. See how far you get into the rabbit hole with even this simple format? I don't mind, as long as it is the right thing to do (IMHO) :) Anyway, I think this could be done on the client side, so we might use your patch without changes. However, I would prefer if the parameter class was more generic, so we could use it (hypothetically) to store time in some other way than LDAP generalized time attribute (at least name it DateTime please). Ok, I'm fine with that. Thanks. The LDAP GeneralizedTime needs to be either in GMT or include a differential. This gets us into the territory where the client could be in a different timezone than the server which leads us to why we dropped AccessTime in the first place. Speaking of time zones, the differential alone is not a sufficient time zone description, as it doesn't account for DST. Is there a way to store time in LDAP with full time zone name (just in case it's needed sometime in future)? There is no way to store DST in LDAP (probably for good reason). Oddly enough the older LDAP v3 RFC (2252) strongly recommends using only GMT but the RFC that obsoletes it (4517) does not include this. Thanks for the info. So I'd like the user to supply the timezone themselves so I don't have to guess (wrongly) and let them worry about differing timezones. We don't have to guess, IIRC there is a way to get the local timezone differential in both Python and JavaScript, so the client could supply it automatically if necessary. I was thinking more about non-IPA clients (like sudo and notBefore). I think this can still be done at least in CLI, but it could be done in a separate patch. Updated patches attached. rob Patch 919 doesn't cleanly apply on current master (neither does 916 BTW).
