[drupal-devel] Help?
by Sheldon Rampton 05 Apr '05

05 Apr '05

OK, I've been trying to use CVS directly, but I've hit a snag. I'm trying to following the instructions for promoting the HEAD of my interwiki module to be the official release for Drupal 4.5. I'm following the instructions at: http://drupal.org/node/17570 However, I get the following result when I enter "cvs tag -F DRUPAL-4-5": >cvs tag: Tagging . >cvs tag: CREDITS.txt: Not moving branch tag `DRUPAL-4-5' from 1.1.2.2 to 1.2. >cvs tag: INSTALL.txt: Not moving branch tag `DRUPAL-4-5' from 1.2.2.2 to 1.3. >cvs tag: README.txt: Not moving branch tag `DRUPAL-4-5' from 1.2.2.2 to 1.4. >cvs tag: interwiki.module: Not moving branch tag `DRUPAL-4-5' from >1.1.2.2 to 1.10. >cvs tag: interwiki.sql: Not moving branch tag `DRUPAL-4-5' from >1.1.2.3 to 1.11. Can someone explain what I need to do? --Sheldon

[drupal-devel] [bug] Brackets should not be used in IDs (primary offender: form_ functions)

Issue status update for http://drupal.org/node/19986 Project: Drupal Version: cvs Component: base system Category: bug reports Priority: critical Assigned to: killes(a)www.drop.org Reported by: factoryjoe Updated by: Bèr Kessels Status: patch can we not expand this into a general ID checker. So that we can be assured of unique ids on any page? Bèr Bèr Kessels Previous comments: ------------------------------------------------------------------------ April 4, 2005 - 23:41 : factoryjoe Attachment: http://drupal.org/files/issues/blah.html (1.13 KB) Square brackets in IDs are not valid XHTML and cause a host of problems when trying to style individual elements. I have attached a page that proves this. Additionally, when you try to style an element by an ID that contains brackets, *all other styling from that rule will be ignored*. Brackets are simply not valid characters for IDs [1] (/emphasis added/): There's also a difference between CLASS and ID attributes as regards to the allowable format of values. By HTML rules, CLASS is CDATA, which basically means 'anything goes', but CSS rules impose some restrictions. /And by HTML rules, ID is ID, which means that only letters of the English alphabet ([A-Za-z]), digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".") are permitted, and the first character must be a letter (and underscores don't work reliably)/ " If you validate the attached document, you will get these two errors: XHTML validation error Line 25, column 19: character "]" is not allowed in the value of attribute "id" <div id="edit-16188][weight"> CSS validation errors Line: 17 Context : #edit-16188 Parse Error - #edit-16188][weight { border: 2px solid blue; } Line: 20 Context : #edit-16188 Parse Error - #edit-16188][weight, #test-2 { border: 2px solid green; } [1] http://css.nu/faq/ciwas-aFAQ.html#QA14 ------------------------------------------------------------------------ April 5, 2005 - 00:50 : killes(a)www.drop.org Attachment: http://drupal.org/files/issues/valid-forms.patch (5.95 KB) Ok, here is an initial patch. The patch needs testing. I introduced a new function _form_get_id that is supposed to replace any non-allowed characters by a dash. This is not really nice, as we will get CSS IDs that have double dashes, but it is valid. We cannot simply reduce the double dashes to single dashes because there already might be another ID with only a single dash. ------------------------------------------------------------------------ April 5, 2005 - 01:29 : gordon This will tidy up the id's of the fields. I have seen this esp. in writing htmlarea as I need to manipulate the ids to remove the [] and other chars. When this is applies please inform Me, and the Authors of FckEditor, and TinyEd as this patch will break the gui editors in some places. This is not a minus, but I myself will like to avoid having the htmlarea module broken for no longer than it needs to.

Hi folks, We've packed up forummail beta 1, you can get it here <http://dev.civicactions.net/?q=CivicGroupsBeta1>. The code is running in a couple of places and things seem ok. Forummail extends the functionality of Mailhandler and Listhandler attempting to make the use of a listserve to "back" or "mirror" a forum as seemless as possible. Feedback encouraged. Dan

[drupal-devel] [feature] Request New Password Security

Also, I just lost my admin password for WP and these are the emails I received at each stage of the process (email titles in bold): *[FactoryCity] Password Reset* "Someone has asked to reset a password for the login this site http://www.factorycity.net/blog [1] Login: admin To reset your password visit the following address, otherwise just ignore this email and nothing will happen. http://www.factorycity.net/blog/wp-login.php?action=resetpass&key=XXXXXf4xx… " *[FactoryCity] Your new password* " Login: admin Password: XxXxXxX http://www.factorycity.net/blog/wp-login.php " *[FactoryCity] Password Lost/Change* "Password Lost and Changed for user: admin " [1] http://www.factorycity.net/blog factoryjoe Previous comments: ------------------------------------------------------------------------ March 11, 2005 - 02:52 : neofactor Problem: Any user can force another user's password to change... simply by selecting "request new password" and putting in their username. The user gets an email with the new.. but this feels like a violation to the user... and a pain. Solution? If someone requests a new password... Don't blindly change it... send an email that says...."Is this a real request authorized by you?

I appreciate your consideration. http://drupal.org/node/18689 ------------------------------------------------------------------------ March 11, 2005 - 04:05 : neofactor I added some code to prevent the admin account from being reset... Please add as a patch. if ($account->uid == 1 { unset($account); form_set_error('name', t('Sorry.

The solution you proposed is rather a workaround and will not be acceptable for core. ------------------------------------------------------------------------ March 11, 2005 - 08:21 : Deno I was in charge of a web site with >10000 paying customers for some time, and the "customers care" was constantly troubled with pasword change requests, until we switched to a system that worked in the following way: 1) "I forgot the password" function accepts either users email, or users login name, generates a random phrase, and adds an entry to "pasword_change_request" table. This entry consists of: - User ID (corresponding to email or login) - random phrase - datestamp User ID is unique key, and the entries in this table older than MAX_TIME are regularly purged by a cron job. 2) System sends an email with a link to "change forgotten password" page with this random phrase as argument to the user. That would be something like: https://drupal.org/user/cfp/d438rwiuodw894732ehdw 3) When user follows the link, "cfp" page checks if the random phrase exists in the table, allows the user to immediately change the password, and sends another email with "your password was changed on RIGHT_NOW ... " note to the user in question. - Password change automatically triggers deleting of the corresponding entry in pasword_change_request table. - Password change automatically logs-in the user as well. This way, users weren't bothered by accidental password changes, and they also understood the system better than the one with automatically generated passwords. For additional security, we also built some brakes that assured that the number of attempts to change the password, such as: - "An email with instructions was sent to you X minutes ago. In case you don't receive it within N hours, please contact the site administrator" - "According to our logs, you have visited the CFP page more than NMAX times within last 24 hours. For security reasons, you will be denied access to this page for the next 24 hours. Please contact the site administrator." hope this helps... ------------------------------------------------------------------------ March 30, 2005 - 20:01 : Jose A Reyero Attachment: http://drupal.org/files/issues/user_one_time_login.patch (6.52 KB) This patch for -cvs- addresses this issue. It generates an *only one use* URL to login into user account, instead of a new password. Then the user clicks on the URL, logs in, and may change his old password if desired. It is a only one use URL, and has some additional security measures, like a configurable time-out -can be confgured in admin/user/settings- and also, if somebody uses it or password is changed in the meanwhile, previously generated login URLs of this type won't work. About how it works, it creates a new url with: - user id, - timestamp - a hash of current timestamp, changed date for account, and the old password hashed With this patch, this wont work for admin accounts, which I think is better, you never know... It has a number of features like: - User can be ignoring these emails if somebody else is requesting access, a new password request wont change current password. However, the user will be warned when seeing the emails - It reveals no sensible information about the user account in the URL itself - the generated hash is not predictable at all if you dont know the old password, as it depends on user's old password - there's a configurable timeout - The URL's are only one use, as they depend on two timestamps, one of which will be changing in case this login is used -or in case user logs in for other means - Any 'new password' request is independent of others, so no one can be interfering with one user asking for his password back. Also doesn't require any new db field nor keeping track of requested passwords. ------------------------------------------------------------------------ March 30, 2005 - 20:41 : chx Very nice patch. Please consider for 4.6. ------------------------------------------------------------------------ March 30, 2005 - 22:16 : drumm Couldn't those nested if statements be made into one with a bit cleaner indentation? It looks like the page which the user arrives at after getting the new login information is their user page, not a page to set the password. The "Time out for password recovery e-mail" configuration is very unfriendly. It should be a drop down select of the most used human readable durations. Or we could just decide on one timeout and leave that hard coded in; who actually needs to use that setting? The url is quite long, what could be done to make it shorter? ------------------------------------------------------------------------ March 30, 2005 - 23:50 : Jose A Reyero /Couldn't those nested if statements be made into one with a bit cleaner indentation?/ Maybe, but I had to split that if conditions in two parts because the $account var didn't get the value before the rest of the conditions -latest two- where evaluated. Someone can help with PHP here? /It looks like the page which the user arrives at after getting the new login information is their user page, not a page to set the password. The "Time out for password recovery e-mail" configuration is very unfriendly. It should be a drop down select of the most used human readable durations. Or we could just decide on one timeout and leave that hard coded in; who actually needs to use that setting?/ Agreed, will be polishing this a little bit, just wating for some more suggestions... For the duration, I'll change to 'hours', ok? Just don't like to restrict options using unneccessary dropdowns, it's only intended for administrators anyway. Maybe I add also a '0' for unlimited. Hardcoding it, would need anyway to be mentioned in the module help, so it's about the same overhead, both for coding and for the admin interface, and harcoding in two places in code is not good anyway. And I like having options, am I the only one? / The url is quite long, what could be done to make it shorter?/ Well, the url has to be long, it has neccessary params and an MD5 hash, which yes, could be cut someway, but that adding inneccessary code and also reducing security -though half an MD5 hash may be secure enough- but I see no point in that. ------------------------------------------------------------------------ March 31, 2005 - 01:18 : FactoryJoe(a)civicspacelabs.org "Or we could just decide on one timeout and leave that hard coded in; who actually needs to use that setting? " +1 for making this *not* configurable! C'mon, Drupal should have standards about security -- and if best practices say that, say, 8 hours, is a good amount of time for that URL to be active, then do that. Cut out the confusion and extra brain juice it takes to decide... "Gee, is 4 hours better than 5?" Additionally, there's a simple way to make this workflow better for the user. If you visit an outdated change password URL, you should be told, "Sorry, but that link you followed to change your password has expired. If you would like to reset your password, please fill out this form: [form] If you did not request to change your password, please notify [administrator's name w/ PM link]". This way, if you missed your change password deadline, you can request your password again right from the timeout page. If you didn't request the change, it will be obvious that someone else was trying to change it, and then you can contact the administrator and find out who it was that was messin' with your account. ------------------------------------------------------------------------ March 31, 2005 - 05:55 : chx Attachment: http://drupal.org/files/issues/user_one_time_login_0.patch (4.72 KB) I cleaned up the patch a bit. I hope code style is OK. So may -- there are no checks against the arguments? There is no need. user_load uses %d for 'uid', so that's dealt with. Comparison by < and > means an implicit cast to integer, so $timestamp is also dealt with automatically. I do not think timeout needs to be configured. Please comment on not letting uid 1 using this one. I am not sure whether this is necessary. ------------------------------------------------------------------------ March 31, 2005 - 06:12 : chx Attachment: http://drupal.org/files/issues/user_one_time_login_1.patch (6.21 KB) Implemented Chris' idea, so if you use a one time URl which is expired, you are sent to user/password with a message to ask for another. I changed a few messages and deleted the "not for admin" feature. Do we really want one gazillion support requests "I locked myself out of my site, user/password tells me not for admin, what now"? ------------------------------------------------------------------------ March 31, 2005 - 07:24 : chx One more point on uid 1. Yes, uid 1 can reset his pwd over the database. But then we would need to lock out administer users privileged users. Then administer nodes, 'cos of XSS. Then administer comments... then administer filters... OK, this is pointless. If someone can eavesdrop on your emails, everything is lost, I think. This is not something Drupal shall address. Maybe we could employ a security question -- secret answer pair. ------------------------------------------------------------------------ March 31, 2005 - 10:52 : Bèr Kessels Eventhough I am a less-settings advocate, I think this must remain a setting :). Why? Sites on Drupal differ a lot, and have a very differnet userbase. I run very low level sites, where it sometimes takes days before someone will read his/her mail. But I also know sites (drupal.org) where days would certainly be too long. Sorry Chris et al, I +1 on configurable duration. (hell, we really need some about:config alike screen in drupal) ------------------------------------------------------------------------ March 31, 2005 - 11:46 : Dries IMO, that setting has nothing to do with a site being "low level". If you request a new password, you probably want to login ASAP. I vote against a configuration option. Either way, this patch needs work: 1. We don't glue words together (eg. $hashedpass, $currenttime, $loginurl). Similarly, I suggest to change 'user/newpassword' to 'user/reset' or 'user/request-password'. 2. The patch exposes technical details to the user; terminology like "one time login URL" is likely to confuse many users. 3. The login URL is not clean URL safe, I think. 4. Please rename the variable $pass1 in user_pass_rehash(). 5. The code comments are often inconsistent. Some end with a punctuation, some don't. Some span two lines, others don't. On a related note, can't we reuse this system for the initial password? That is, instead of mailing a password, we mail an URL and force the user to enter a password. ------------------------------------------------------------------------ March 31, 2005 - 17:20 : Jose A Reyero Attachment: http://drupal.org/files/issues/user_one_time_login_2.patch (12.77 KB) Ok, I've started with chx's reviewed patch, and done most of Dries suggestions Main changes are: ----------------------- - Rewording, variable names, path, etc... as pointed out by Dries. Now it's user/reset. And yes, it was not clean-URL safe; it is now. - Allowed also for admin account, I dont like it though, but seem to be the only one :( - Used also for user registration, but I also kept old style login/password, think it can be some use and anyway, it's up to the site admin to remove it from the welcome e-mail. However it is only for 'no admin approval', see below about this.... - Added back in the config option for time-out, though reworked completely for usability. Default is '1 day' which I think should be reasonable. However, there's no time out for firts time users. About this, read below, please... ----------------------- Using this for first time login has some problems when admin aproval is required, as the hashed pass depends on 'changed' timestamp, and it changes when the admin approves an account. Actually, there's no way to know -or I didn't find it- when it is the first login for an approved account. For no admin approval, I just used 'changed' == 'created' as a criterium. I think we should be separating this changed date and last login date creating a new field in the user table, but that maybe for a future patch. That would also increase security, as the Administrator's info would be more accurate, and 'last login date' could be shown when user logs in, which is also security+ Related with this I've experienced problems, as administrator, when editing user accounts, then last login info for the users gets lost -is reset-... About the config option for time out, though I agree that enforcing security can be good in general, this is one of this cases where more security means less usability. And that decission should be left to Site administrators -each site has its own security requirements-. So I think the target here should be a 'reasonable' default, and then some flexibility for site admins. IMHO this latest patch is quite well balanced. So... everybody happy? ------------------------------------------------------------------------ March 31, 2005 - 19:43 : Dries "So ... everyone happy?" Not quite. The patch is an improvement but it uses tabs, incorrect spacing, incorrect placement of brackets, and does not use theme('placeholder'). If a new database column is required to implement this properly, please add one. This patch won't get committed until it is implemented properly. I still vote to remove the configuration option. We're getting there ... ------------------------------------------------------------------------ April 2, 2005 - 18:45 : factoryjoe I’m going to have to stick by my earlier assertion on this one, and, and, as with most usability issues, none of us are “correct” until we test it 50 times and see whether anyone actually uses the option. Just like with my folksonomy review [2], more options is *not always better* nor does it always help people *get things done*! To further expand this point, Jose says [3]: About the config option for time out, though I agree that enforcing security can be good in general, this is one of this cases where more security means less usability. And that decission should be left to Site administrators -each site has its own security requirements. " But this is a misuse of the term “usability”. What you’re talking about is *functionality*—since usability has more to do with focusing single-mindedly on the task at hand and reducing distraction than it does with providing extraneous options that might be useful for a fraction of all Drupal admins. To speak to Ber’s point [4], I cannot imagine a situation where, if I want to change my password because I’ve forgotten it, that it will take more than a few hours to get the email and fulfill the process. And even still, if it does — for whatever reason — take me a week to get around to resetting my password, then starting the process over again isn’t all that time consuming. Plus, I have the added sense of security that Drupal doesn’t let things like password resetting links stay active forever! So again, I agree that we need a reasonable default—24 hours is very generous for the singular task that we’re trying to serve here, which is, to my knowledge, to make the process for resetting your password easier and more secure. Lastly, about the patch itself: I noticed a couple <em> tags strewn around in lines 38, 43, 54 and 72 (as well as a <strong> on 54). Until we have a style guide for marking up usernames, should we really be using HTML like this? It seems to be that it would be better to use a span with a class of… say… “username” and let the themer determine whether the username should be bold, italicized, red, all caps and so on.*/ [2] http://drupal.org/node/19697#comment-25599 [3] http://drupal.org/node/18719#comment-25480 [4] http://drupal.org/node/18719#comment-25463 ------------------------------------------------------------------------ April 2, 2005 - 20:29 : factoryjoe One other quick question. How does this patch interact with distributed authentication? If I'm logged in with a remote account and ask to reset my password, what happens? ------------------------------------------------------------------------ April 3, 2005 - 09:22 : Dries factoryjoe: you can't reset your password when you are logged in. ------------------------------------------------------------------------ April 3, 2005 - 13:03 : Jose A Reyero About usability I've written this piece [5], so I really prefer to discuss it on the forums... That patch, I'll be cleaning it up a little bit, adding that last login field, and maybe go for that 'reasonable default', which anyway is not worth so much discussion.... [5] http://drupal.org/node/19918 ------------------------------------------------------------------------ April 5, 2005 - 00:20 : Jose A Reyero Attachment: http://drupal.org/files/issues/user_one_time_login_3.patch (20.26 KB) Ok, lets try to make people happy, which will be good for my karma, I hope so ;-) So, changes: - Added 'lastlogin' field to user table. Now there's one timestamp for when an account is edited and another one for login. Of course, I've also taken care of the user's admin page. - Some small detail like help text for e-mail fields and that. - Now it can be used also for accounts with admin approval. - And yes, removed config option, 1 day time out for password recovery, no time out for first login. By the way, I've also patched db files for PostgreSQL, please someone review it, I don't know too much about it. The default e-mails may need better wording. Specially the one for password recovery which just says 'You have requested a new password', but I dont want users get too worried in case someone else has requested that password and the old one that said something like 'This is your new login information..' which may suggest it has been sent by the admin maybe updating accounts..... Anyway, every site admin can configure that email... As an idea for the future or for someone else - I've had enough for now with logging in 100 times to try this-, now that we can know when it is the first login for an user, a nice welcome message or welcome screen would be great :-) Or if someone wants to go for better security *nix style, some message telling the user when last logged in wouldn't be bad... So... ?

The solution you proposed is rather a workaround and will not be acceptable for core. ------------------------------------------------------------------------ March 11, 2005 - 09:21 : Deno I was in charge of a web site with >10000 paying customers for some time, and the "customers care" was constantly troubled with pasword change requests, until we switched to a system that worked in the following way: 1) "I forgot the password" function accepts either users email, or users login name, generates a random phrase, and adds an entry to "pasword_change_request" table. This entry consists of: - User ID (corresponding to email or login) - random phrase - datestamp User ID is unique key, and the entries in this table older than MAX_TIME are regularly purged by a cron job. 2) System sends an email with a link to "change forgotten password" page with this random phrase as argument to the user. That would be something like: https://drupal.org/user/cfp/d438rwiuodw894732ehdw 3) When user follows the link, "cfp" page checks if the random phrase exists in the table, allows the user to immediately change the password, and sends another email with "your password was changed on RIGHT_NOW ... " note to the user in question. - Password change automatically triggers deleting of the corresponding entry in pasword_change_request table. - Password change automatically logs-in the user as well. This way, users weren't bothered by accidental password changes, and they also understood the system better than the one with automatically generated passwords. For additional security, we also built some brakes that assured that the number of attempts to change the password, such as: - "An email with instructions was sent to you X minutes ago. In case you don't receive it within N hours, please contact the site administrator" - "According to our logs, you have visited the CFP page more than NMAX times within last 24 hours. For security reasons, you will be denied access to this page for the next 24 hours. Please contact the site administrator." hope this helps... ------------------------------------------------------------------------ March 30, 2005 - 21:01 : Jose A Reyero Attachment: http://drupal.org/files/issues/user_one_time_login.patch (6.52 KB) This patch for -cvs- addresses this issue. It generates an *only one use* URL to login into user account, instead of a new password. Then the user clicks on the URL, logs in, and may change his old password if desired. It is a only one use URL, and has some additional security measures, like a configurable time-out -can be confgured in admin/user/settings- and also, if somebody uses it or password is changed in the meanwhile, previously generated login URLs of this type won't work. About how it works, it creates a new url with: - user id, - timestamp - a hash of current timestamp, changed date for account, and the old password hashed With this patch, this wont work for admin accounts, which I think is better, you never know... It has a number of features like: - User can be ignoring these emails if somebody else is requesting access, a new password request wont change current password. However, the user will be warned when seeing the emails - It reveals no sensible information about the user account in the URL itself - the generated hash is not predictable at all if you dont know the old password, as it depends on user's old password - there's a configurable timeout - The URL's are only one use, as they depend on two timestamps, one of which will be changing in case this login is used -or in case user logs in for other means - Any 'new password' request is independent of others, so no one can be interfering with one user asking for his password back. Also doesn't require any new db field nor keeping track of requested passwords. ------------------------------------------------------------------------ March 30, 2005 - 21:41 : chx Very nice patch. Please consider for 4.6. ------------------------------------------------------------------------ March 30, 2005 - 23:16 : drumm Couldn't those nested if statements be made into one with a bit cleaner indentation? It looks like the page which the user arrives at after getting the new login information is their user page, not a page to set the password. The "Time out for password recovery e-mail" configuration is very unfriendly. It should be a drop down select of the most used human readable durations. Or we could just decide on one timeout and leave that hard coded in; who actually needs to use that setting? The url is quite long, what could be done to make it shorter? ------------------------------------------------------------------------ March 31, 2005 - 00:50 : Jose A Reyero /Couldn't those nested if statements be made into one with a bit cleaner indentation?/ Maybe, but I had to split that if conditions in two parts because the $account var didn't get the value before the rest of the conditions -latest two- where evaluated. Someone can help with PHP here? /It looks like the page which the user arrives at after getting the new login information is their user page, not a page to set the password. The "Time out for password recovery e-mail" configuration is very unfriendly. It should be a drop down select of the most used human readable durations. Or we could just decide on one timeout and leave that hard coded in; who actually needs to use that setting?/ Agreed, will be polishing this a little bit, just wating for some more suggestions... For the duration, I'll change to 'hours', ok? Just don't like to restrict options using unneccessary dropdowns, it's only intended for administrators anyway. Maybe I add also a '0' for unlimited. Hardcoding it, would need anyway to be mentioned in the module help, so it's about the same overhead, both for coding and for the admin interface, and harcoding in two places in code is not good anyway. And I like having options, am I the only one? / The url is quite long, what could be done to make it shorter?/ Well, the url has to be long, it has neccessary params and an MD5 hash, which yes, could be cut someway, but that adding inneccessary code and also reducing security -though half an MD5 hash may be secure enough- but I see no point in that. ------------------------------------------------------------------------ March 31, 2005 - 02:18 : FactoryJoe(a)civicspacelabs.org "Or we could just decide on one timeout and leave that hard coded in; who actually needs to use that setting? " +1 for making this *not* configurable! C'mon, Drupal should have standards about security -- and if best practices say that, say, 8 hours, is a good amount of time for that URL to be active, then do that. Cut out the confusion and extra brain juice it takes to decide... "Gee, is 4 hours better than 5?" Additionally, there's a simple way to make this workflow better for the user. If you visit an outdated change password URL, you should be told, "Sorry, but that link you followed to change your password has expired. If you would like to reset your password, please fill out this form: [form] If you did not request to change your password, please notify [administrator's name w/ PM link]". This way, if you missed your change password deadline, you can request your password again right from the timeout page. If you didn't request the change, it will be obvious that someone else was trying to change it, and then you can contact the administrator and find out who it was that was messin' with your account. ------------------------------------------------------------------------ March 31, 2005 - 06:55 : chx Attachment: http://drupal.org/files/issues/user_one_time_login_0.patch (4.72 KB) I cleaned up the patch a bit. I hope code style is OK. So may -- there are no checks against the arguments? There is no need. user_load uses %d for 'uid', so that's dealt with. Comparison by < and > means an implicit cast to integer, so $timestamp is also dealt with automatically. I do not think timeout needs to be configured. Please comment on not letting uid 1 using this one. I am not sure whether this is necessary. ------------------------------------------------------------------------ March 31, 2005 - 07:12 : chx Attachment: http://drupal.org/files/issues/user_one_time_login_1.patch (6.21 KB) Implemented Chris' idea, so if you use a one time URl which is expired, you are sent to user/password with a message to ask for another. I changed a few messages and deleted the "not for admin" feature. Do we really want one gazillion support requests "I locked myself out of my site, user/password tells me not for admin, what now"? ------------------------------------------------------------------------ March 31, 2005 - 08:24 : chx One more point on uid 1. Yes, uid 1 can reset his pwd over the database. But then we would need to lock out administer users privileged users. Then administer nodes, 'cos of XSS. Then administer comments... then administer filters... OK, this is pointless. If someone can eavesdrop on your emails, everything is lost, I think. This is not something Drupal shall address. Maybe we could employ a security question -- secret answer pair. ------------------------------------------------------------------------ March 31, 2005 - 11:52 : Bèr Kessels Eventhough I am a less-settings advocate, I think this must remain a setting :). Why? Sites on Drupal differ a lot, and have a very differnet userbase. I run very low level sites, where it sometimes takes days before someone will read his/her mail. But I also know sites (drupal.org) where days would certainly be too long. Sorry Chris et al, I +1 on configurable duration. (hell, we really need some about:config alike screen in drupal) ------------------------------------------------------------------------ March 31, 2005 - 12:46 : Dries IMO, that setting has nothing to do with a site being "low level". If you request a new password, you probably want to login ASAP. I vote against a configuration option. Either way, this patch needs work: 1. We don't glue words together (eg. $hashedpass, $currenttime, $loginurl). Similarly, I suggest to change 'user/newpassword' to 'user/reset' or 'user/request-password'. 2. The patch exposes technical details to the user; terminology like "one time login URL" is likely to confuse many users. 3. The login URL is not clean URL safe, I think. 4. Please rename the variable $pass1 in user_pass_rehash(). 5. The code comments are often inconsistent. Some end with a punctuation, some don't. Some span two lines, others don't. On a related note, can't we reuse this system for the initial password? That is, instead of mailing a password, we mail an URL and force the user to enter a password. ------------------------------------------------------------------------ March 31, 2005 - 18:20 : Jose A Reyero Attachment: http://drupal.org/files/issues/user_one_time_login_2.patch (12.77 KB) Ok, I've started with chx's reviewed patch, and done most of Dries suggestions Main changes are: ----------------------- - Rewording, variable names, path, etc... as pointed out by Dries. Now it's user/reset. And yes, it was not clean-URL safe; it is now. - Allowed also for admin account, I dont like it though, but seem to be the only one :( - Used also for user registration, but I also kept old style login/password, think it can be some use and anyway, it's up to the site admin to remove it from the welcome e-mail. However it is only for 'no admin approval', see below about this.... - Added back in the config option for time-out, though reworked completely for usability. Default is '1 day' which I think should be reasonable. However, there's no time out for firts time users. About this, read below, please... ----------------------- Using this for first time login has some problems when admin aproval is required, as the hashed pass depends on 'changed' timestamp, and it changes when the admin approves an account. Actually, there's no way to know -or I didn't find it- when it is the first login for an approved account. For no admin approval, I just used 'changed' == 'created' as a criterium. I think we should be separating this changed date and last login date creating a new field in the user table, but that maybe for a future patch. That would also increase security, as the Administrator's info would be more accurate, and 'last login date' could be shown when user logs in, which is also security+ Related with this I've experienced problems, as administrator, when editing user accounts, then last login info for the users gets lost -is reset-... About the config option for time out, though I agree that enforcing security can be good in general, this is one of this cases where more security means less usability. And that decission should be left to Site administrators -each site has its own security requirements-. So I think the target here should be a 'reasonable' default, and then some flexibility for site admins. IMHO this latest patch is quite well balanced. So... everybody happy? ------------------------------------------------------------------------ March 31, 2005 - 20:43 : Dries "So ... everyone happy?" Not quite. The patch is an improvement but it uses tabs, incorrect spacing, incorrect placement of brackets, and does not use theme('placeholder'). If a new database column is required to implement this properly, please add one. This patch won't get committed until it is implemented properly. I still vote to remove the configuration option. We're getting there ... ------------------------------------------------------------------------ April 2, 2005 - 19:45 : factoryjoe I’m going to have to stick by my earlier assertion on this one, and, and, as with most usability issues, none of us are “correct” until we test it 50 times and see whether anyone actually uses the option. Just like with my folksonomy review [1], more options is *not always better* nor does it always help people *get things done*! To further expand this point, Jose says [2]: About the config option for time out, though I agree that enforcing security can be good in general, this is one of this cases where more security means less usability. And that decission should be left to Site administrators -each site has its own security requirements. " But this is a misuse of the term “usability”. What you’re talking about is *functionality*—since usability has more to do with focusing single-mindedly on the task at hand and reducing distraction than it does with providing extraneous options that might be useful for a fraction of all Drupal admins. To speak to Ber’s point [3], I cannot imagine a situation where, if I want to change my password because I’ve forgotten it, that it will take more than a few hours to get the email and fulfill the process. And even still, if it does — for whatever reason — take me a week to get around to resetting my password, then starting the process over again isn’t all that time consuming. Plus, I have the added sense of security that Drupal doesn’t let things like password resetting links stay active forever! So again, I agree that we need a reasonable default—24 hours is very generous for the singular task that we’re trying to serve here, which is, to my knowledge, to make the process for resetting your password easier and more secure. Lastly, about the patch itself: I noticed a couple <em> tags strewn around in lines 38, 43, 54 and 72 (as well as a <strong> on 54). Until we have a style guide for marking up usernames, should we really be using HTML like this? It seems to be that it would be better to use a span with a class of… say… “username” and let the themer determine whether the username should be bold, italicized, red, all caps and so on.*/ [1] http://drupal.org/node/19697#comment-25599 [2] http://drupal.org/node/18719#comment-25480 [3] http://drupal.org/node/18719#comment-25463 ------------------------------------------------------------------------ April 2, 2005 - 21:29 : factoryjoe One other quick question. How does this patch interact with distributed authentication? If I'm logged in with a remote account and ask to reset my password, what happens? ------------------------------------------------------------------------ April 3, 2005 - 10:22 : Dries factoryjoe: you can't reset your password when you are logged in. ------------------------------------------------------------------------ April 3, 2005 - 14:03 : Jose A Reyero About usability I've written this piece [4], so I really prefer to discuss it on the forums... That patch, I'll be cleaning it up a little bit, adding that last login field, and maybe go for that 'reasonable default', which anyway is not worth so much discussion....

[drupal-devel] [bug] Brackets should not be used in IDs (primary offender: form_ functions)

The patch needs testing. I introduced a new function _form_get_id that is supposed to replace any non-allowed characters by a dash. This is not really nice, as we will get CSS IDs that have double dashes, but it is valid. We cannot simply reduce the double dashes to single dashes because there already might be another ID with only a single dash. killes(a)www.drop.org Previous comments: ------------------------------------------------------------------------ April 4, 2005 - 23:41 : factoryjoe Attachment: http://drupal.org/files/issues/blah.html (1.13 KB) Square brackets in IDs are not valid XHTML and cause a host of problems when trying to style individual elements. I have attached a page that proves this. Additionally, when you try to style an element by an ID that contains brackets, *all other styling from that rule will be ignored*. Brackets are simply not valid characters for IDs [1] (/emphasis added/): There's also a difference between CLASS and ID attributes as regards to the allowable format of values. By HTML rules, CLASS is CDATA, which basically means 'anything goes', but CSS rules impose some restrictions. /And by HTML rules, ID is ID, which means that only letters of the English alphabet ([A-Za-z]), digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".") are permitted, and the first character must be a letter (and underscores don't work reliably)/ " If you validate the attached document, you will get these two errors: XHTML validation error Line 25, column 19: character "]" is not allowed in the value of attribute "id" <div id="edit-16188][weight"> CSS validation errors Line: 17 Context : #edit-16188 Parse Error - #edit-16188][weight { border: 2px solid blue; } Line: 20 Context : #edit-16188 Parse Error - #edit-16188][weight, #test-2 { border: 2px solid green; } [1] http://css.nu/faq/ciwas-aFAQ.html#QA14

[drupal-devel] New Archive Archive Module
by CodeMonkeyX 04 Apr '05

04 Apr '05

The current archive module for Drupal is inadequate, plain and simple. You are presented with a simple three-part form with the year, month, and day. You enter the date of the post you are looking for, and hit submit. If you do not happen to know the exact day that a post was made you are out of luck. Another problem with the current archive module is the fact that it uses a form to browse the archive. Because a form is used no feedback about the users current location in the archive is displayed in the url. So it is nearly impossible to link to a specific part of the archives. So my new module had a few features that I really felt were required. * Navigation: a new system for navigating the archives was required. The new system should provide a more granular way for users to browse the archive by date or by node type. * URL Feedback: provides the user with a familiar way to keep track of their position in the archive, and also provides a easy way for people to link to specific areas of the archive. * Filter by Date or Type: the old module just displayed all nodes. I thought it would be better if the user to specify if they wanted to view only blog nodes, or forum nodes, etc. These are the features that are in the demo I am currently using on my site. It is still under development, but if all goes well maybe this will become a part of the Drupal core for the 4.7 release. We will see how it goes. You can read more on my site: http://www.codemonkeyx.net/node/221 View a Demo: http://www.codemonkeyx.net/archive Tell me what you think, and what could be done to make it better.
