Official bug number for regex bug?

Is there an official bug number for this regex bug?
SELECT regexp_substr('foo, bar, qux,', '.*b.*?,') FROM dual
returns "foo, bar, qux," instead of "foo, bar," in Oracle 11g R2.
Note that this is definitely a bug, as
SELECT regexp_substr('foo, bar, qux,', '.*b.{0,}?,') FROM dual
correctly returns "foo, bar,"

  • How pervasive is this regex bug?  Is there an official bug ID?

    Oracle has a bug in their regular expression handling in 10g 2 and 11g 2. Is this bug also in XE? If so, does it have a bug number I can reference? I don't have support, I'm just evaluating Oracle Database offerings for our company.
    The bug: With 10g 2 Oracle released support for non-greedy quantifiers in regular expressions. See http://docs.oracle.com/cd/E11882_01/appdev.112/e25518/adfns_regexp.htm#autoId6
    However, it has bugs.

    foo, bar,and same results on SQL*Plus: Release 11.2.0.1.0 Production. This is obviously a bug. One can argue about the differing possible interpretations of the sequence `.\*?`, but there is nothing that suggest `b.\*,` shouldn't pick up `qux`. I have a dozen other examples if you want. So my question is that since this has been a bug in released production code for over a year, is there a bug/defect number I can use to track it's eventual resolution? I don't have a support contract to ask support directly because I'm just evaluating right now. I'm trying to push for Oracle but bugs like this make it hard for me to use the argument that Oracle is relatively bug free.
    Fixed * interpreted as markup

    Oracle has a bug in their regular expression handling in 10g 2 and 11g 2. Is this bug also in XE?If a bug exists in Oracle Database 11.2.0.2, it's very likely to exist in 11.2 XE as well, as 11.2 XE is based on that version.
    and same results on SQL*Plus: Release 11.2.0.1.0 ProductionThis is no matter of SQL*Plus, as this is only the client, while the query you execute is processed by the database you're connected to.
    Despite that, I wonder how it comes you have SQL*Plus 11.2.0.1.0 on your machine, because XE ships with 11.2.0.2. But this has no impact on your issue...
    but there is nothing that suggest `b.*,` shouldn't pick up `qux`. I'm not sure about that. It's a question of where your "preceding" definition ends and how you interprete the documentation. See the differences (or no difference) when using subgroups to separate greedy and nongreedy operators explicitly, e. g.
    select regexp_substr('foo, bar, qux, ','.*?(b.*,)') from dual;
    -- or even
    select regexp_substr('foo, bar, qux, ','(.*?b)(.*,)') from dual; return foo, bar,, which would fit the "first string to match" strategy documented for regexp_substr.
    On the other hand, you could enforce the behaviour you seem to expect with making the greedy subgroup explicit.
    select regexp_substr('foo, bar, qux, ','.*?b(.*,)') from dual;
    -- or
    select regexp_substr('foo, bar, qux, ','(.*b)(.*?,)') from dual; will return your complete string.
    Of course, you can always argue on whether you should "reuse" characters for different groups when evaluating the regex. From my personal experience, using explicit subgroups helps structuring (and understanding) your regex and makes moving through different implementations easier...
    I'm trying to push for Oracle but bugs like this make it hard for me to use the argument that Oracle is relatively bug free.This is mostly a point of view, as your "relatively" indicates...

  • How to submit a bug report for OSB? - restore fails if number of items per page is changed from the default of 30

    In the OSB web gui, one of my users found that if the number of items per page is changed from the default of 30, the restore of the file will fail.  He tested this using recent versions of Firefox and IE.  We have verified this to also be the case using Chrome.
    In a directory containing over 100,000 files, moving 30 at a time to find the one to be restored is a very frustrating user experience.
    How do I file a bug report for this issue?  Is there a workaround for this bug to enable my users to more easily find the file to restore without being restricted to the default of 30 items per page?

    Yes there is a bug in the webtool in the current release. You can use the commandline obtool to do the restore, that is much faster and works fine.
    Thanks

  • New number of posts bug(?) + question; no #100, and total # of posts vary

    New number of posts bug(?) + question; no number 100, and total number of posts vary
    Intrigued by Tuttle's new attempt to join Niel's old habit to keep his own total number of posts count, I went and start counting my posts since the New Discussions. Because I saved my latest Old Discussions Post-and-Points info, I can see what are the previously-still-online ones (the pre- 14-Nov-2005 01:31 GMT ones), and I know exactly what was my "real" total number of posts before 14-Nov-2005 (2446).
    My New Discussions posts number however, is quite uncertain.
    Firstly, when I use the "My Posts" link on the right, then clicking on and on on the "Next" link,
    my "Viewing 91-100 of 586 -- Pages" shows 91-99 instead of 91-100
    (= should show 10 posts, shows 9 posts)
    then I go on clicking Next Next Next, and I see the same missing counts happen elsewhere:
    my posts number 100, 259, 260, 370, 390, 520, 558, 559, 560, 578, 579, and 580 are missing too.
    Note that I wouldn't bother doing all this, and I would have thought it's just very old posts that are automatically deleted like in the Old Discussions,
    BUT,
    the problem is that when I choose to see all my posts together on the same page
    (by using the start=0&range=600 suffix in the URL)
    I get a total number of posts that is different (570).
    A third way to quickly see all posts without having to load too big page
    (using the start=0&range=300 suffix in the URL then only one "Next" click)
    shows yet another, different again, number of total posts (573).
    And my "official" total number of posts is (586).
    Dear HOSTS,
    - If this can be used as a bug report to fix a counting problem, glad to help.
    - If there is no bug, I have two(+) questions then:
    1) Was my post number 100 deleted?
    (should be around 27-Nov-2005 18:00 GMT)
    Also:
    I thought the Total Posts number that we see in "My Public Profile" or under the avatar in each post (586), was only the number of posts still online.
    - if it is the case, then there are no automatically deleted old posts anymore?
    - if old posts are automatically deleted like before, this number should vary?
    - if it doesn't vary (it just grows by one per new post), AND at the same time old posts are actually automatically deleted,
    it has to show the "real" total number of posts then,
    (as it is now, a total starting from the Old-Discussions-still-online-posts, it makes no sense),
    that is,
    the total posts in the New Discussions PLUS the total posts since first registration in the Old Discussions.
    So,
    2) What does it show exactly?
    Thanks again for all the great work!
    Axl
    220? 221?

    Thank you Andreas,
    Your confirmation about the "post #100 bug" does help.
    "As for your other missing posts - I guess Tuttle's assessment that they might be deleted is probably right..."
    Yes, that makes sense and that's what I'm trying to figure in my OP, but then,
    after I posted my "#221/2667 post" (11-Dec-2005 21:51 GMT), my originally missing #
    259, 260, 370, 390, 520, 558, 559, 560, 578, 579, and 580
    should have become
    260, 261, 371, 391, 521, 559, 560, 561, 579, 580, and 581
    right? (forget the #100: this one we know for sure it's a bug)
    Or if the software counts them from the first (now that would have been a good start) instead of starting from the most recent,
    they should become
    258, 259, 369, 389, 519, 557, 558, 559, 577, 578, and 579
    Well, that's not what happened. Now the missing # are
    259, 260, 370, 390, 400, 520, 559, 560, 570, 579, and 580
    (in addition to the same #100) (#558 and 578 not missing anymore).
    As you can see, there is no logic:
    It doesn't work as a simple numerotation of StillOnlinePosts, no matter the order
    (otherwise there would simply be a straight count from 1 to 575 (=587-12).
    It looks indeed like it shows which old posts are being automatically deleted. That the numbers are quite the same would simply show that the old posts dates were so close, of course they are deleted (six months later) almost at the same time,
    BUT,
    if it was the case, there would never be LESS deleted posts between two StillOnlinePosts, like it happens for example between my StillOnlinePosts #557 and #561.
    Please note: of course I stick to the same method to make all my counts. Not manually modifying the URL, just using the default Next-Next-Next- clicking...
    Modifying URL would add yet more differences in the differences!..
    Dear Hosts,
    Too bad it doesn't help looking yourself at my "My Posts", as everything changes each time I'm adding a reply somewhere.
    Perhaps a good way to troubleshoot this would be to start from a very simple basis:
    --> "name" the posts with a number, starting from the oldest.
    This way, for example my "#1" post (11-Dec-2005 21:51 GMT in this thread) would be named "221" in the New Discussions, or "2667" if you start from my Registration date.
    At the moment, it is very difficult to figure what fault comes from the "#100 post bug" and what fault comes from another possible counting bug...
    Then the New Discussions "fluctuating" refreshing delay too, possibly messes the counts...
    Thanks!

  • Security exceptions not configurable after release 31 (bug number 1042889 is not fixed)

    We are running Firefox 31 32 and 33 on different machines on windows/XP (updated until end of support).
    Our router has an expired certificate. On the machines updated to Firefox 32 or above the security popup screen does not show. Instead we just get the corresponding error message, when trying to access the router's homepage.
    I looked at the support thread "Secure Connection Failed- can not confirm security exception (since update to 31)" .
    The posted solutions do NOT work!
    Chrome and even IE work fine.
    Please take a look at what was changed and reverse it.
    Or add a possibility to configure exceptions to the always accessible options tab "security", Having only 262 users with the same problem, means all others having the problem just moved to other browsers.
    For someone using Firefox since the beginning and liking it this will be a hard step, so I raise the issue again.
    No, buying a new router is NOT an option, because it manages our network storage and printers and the rule is "never fix a running system".

    hello, the fix of the bug number you have referred to has already landed in firefox 31.2.0 esr and will land in the regular firefox release channel in case there is an update to firefox 33 or else in version 34.

  • E52 bug list for advanced users

    I wanted to start the compilation of a bug list for advanced users. Here is my first suggestion:
    1. SMS Functionality: 
    When trying to send SMS to a distribution list, the phone interface will ask you to choose between number and email addresses, even though the phone does understand that this is a SMS and not an email ("Text Message" appering on top)
    This happens even when the contact has one phone number only (and an email address) in the phonebook
    This does not happen when you use PC Suite to do the same task
    2. Mail for Exchange client:
    I will not go through the many -most already reported- bugs and general instability of the client. However, I will mention two that I have not seen reported anywhere so far:
    When forwarding emails, only the header (From/To/Date/Subject) is forwarded. The rest of the text, as well as possible atachments are not forwarded. This is happening -to my epxerience- every time you try to forward an email
    The client doesn't provide information (like the previous, installable client for devices such as E51, E71, etc.) as to when was the last time that sync took place, while it also doesn't show a real-time progress like the previous one. These two functionalities were very useful for controlling the Mail for Exchange process and understanding proactively if there was an issue. I consider these a must for any Business user (going through the log files to understand the same thing is obviously utterly impractical)
    The client doesn't synchronise the "Deleted Items" folder from the mail server but only locally (which means it includes emails that were deleted only from the device itself).
    The synchronization of the folders other than "Inbox" should be happening ad-hoc whenever the user is accessing these folders and requesting a sunchronization. Otherwise, we see the phenomenon of extremely lengthy synchronizations
    3.  Screen/Display:
    It would be nice, when using the smallest font, to also accordingly compress the menu choices, in order to be able to fit more on the screen. Otherwise, with the present implementation, the fonts get smaller, but the relevant menu icons are not, resulting in an assymetrical look
    4. Ovi suite:
    As a general comment, I would like to mention that -apart from totally unknown NOKIA policy with regards to Ovi vis-a-vis PC Suite- it is not appropriate for Ovi to contain less functionality than PC Suite (I am referring to SMS presentation, etc.). In general, I find Ovi much clunkier and more clumsy than PC Suite which has actually evolved well over the years as the absolute PC phone tool (and still a differentiator for Nokia). So, NOKIA, please do not screw up PC Suite for something that may be "hype" accoridng to you, but is used as a tool by many of your customers.
    5. Log:
    As in previous phones/firmware versions, when setting the Log to 30 days, only 7 or ten days are actually retained. Maybe related to phone memory, but in any case it is a nuissance
    6. SMS/VMs/Missed calls notifications:
    This is not a bug, but at least personally, I preffered the way the SMS/VMs/Missed calls notifications were displayed in the previous devices (E51, etc.), just below the active stand-by applications "ribbon", instead of at the bottom of the screen. The new implementation makes it harder to access these items than before (at least for me)
    I appeal to NOKIA to consider and fix these issues in the next firmware release(s).
    Timos Tsokanis

    @Timos , great compilation. I hope Nokia will work to resolve these quickly.
    I have been using phone since last 2-3 days and find few things in Email client really annoying.
    Also I want to understand few settings in Email client (version 2.1.0). They have made settings too complicated.
    1)Any folder except Inbox doesn't show unread email count in brackets next to folder names.
    i.e. If i delete or move 2 emails which I have not read to any folder(Deleted etc) , then deleted folder should be like Deleted(2). But right now it doesnt show anything. Strange.
    I have checked with E72 and this bug is not there.
    2) I have Gmail, Hotmail and Ovi mail as part of Nokia Messaging. But only Gmail and Hotmail actually show up when I open Messaging. All 3 show up if I open Email.
    3)What does "Download Notification" under Global settings do? Notification icon control?
    4) Why my Name field in Mailbox setting is picked from account at email.nokia.com, also even though secure connection is Yes under server settings in email.nokia.com, for same email its No in email client.
    5) Why I am not allowed to change settings in "What to sync" , e.g. Hide email older than
    6) what do settings "synchronise new updates" , "timed sync" do? No explaining in help.
    7) Setting ->Gmail(or any other)->Account settings->Account Info, why number is blank? Also please make this work with destinations support. Also connectivity setting should be in global settings.

  • Bug fix for Mac book wireless - problem solved!

    Aparantly there is a rather large number of folks out there who've discovered this dillema with wireless not working very well at this point on the Macbook.
    Well, I can attest there is one very good solution out there for this issue. This application called Sonar Theater from www.sunray.tv includes a bug fix for the wireless connection issues with Macbook in their latest 1.5 release of Sonar Theater.
    I downloaded it, put it into my start up folder and waalaa! problem solved. I've haven't any more issues with dropped wireless since - it's been running constantly for over 2 weeks now.
    I haven't even attempted to touch my router configuration - don't need to.

    Welcome to the better life of Macs. I am using Sonar Theater too and it's been working very well for me. In fact, I'm getting hooked on just texting a message to my Mac book to fire up user sessions now. I think if you give the Mac Book some time however, you'll find that there really is no comparison to PC's. Your life overall is going to just keep getting better as you dig in to the resources available to new Mac users.
    I'm sure it seems confusing to PC users at first, but here's how to set up any application as part of your startup sequence. It really is extremely easy and simple compared to the PC world. Oh and by the way, in reality, Mac users refer to this as your login sequence. So, at login time, you can do a multitude of different things for each user account you might want to set up. Naturally, you can choose to share or not share applications and data between these user accounts on your Mac too....
    Mac OS X 10.3 or later
    1. Log in as the user who wishes to have a login item or as an admin user.
    2. Choose System Preferences from the Apple menu.
    3. Choose Accounts from the View menu.
    4. Click the name of the user.
    5. Click the Startup Items button
    6. Click the "Add {+}" button.
    The item you selected will automatically open the next time you log in.
    there are several ways to get good info from the apple community on tips and tricks as well. you should just try the apple os x web site...here,

    Fix for a bug: After playing a hide effect, a window wouldn't be visible again.
    The issue here is that all effects that occur because of HIDE end up calling setVisible() (see EffectManager.effectEndHandler).  Window/WindowedApplication was basically left with two concepts of setVisible...the displayObject one and the native application one, and they were out of synch.  So setting visible=true on the window wasn?\226?\128?\153t calling setVisible(true) which controls the display object visibility.  Now instead of doing our work in the visible setter, we override setVisible() and do it in there.

    I run Suse 9.1 Linux, and Suse has a package called lmsensors which by default on my machine gives readings like this:
    Code: [Select]
    temp1:       +27°C  (high =    +0°C, hyst =   +22°C)   sensor = thermistor
    temp2:     +41.0°C  (high =   +80°C, hyst =   +75°C)   sensor = PII/Celeron diode 
    Now that 41C is pretty high for an idle AMD643000+ running at 1000Mhz, 1.08V. Too high, I would say. temp 1 in this case is the SYS temp, temp2 is the CPU temp.
    Now, using lmsensors I can duplicate your little trick and tell it that temp 2 is in fact a 3904 transistor. Having done this can I get readings like this:
    Code: [Select]
    temp1:       +27°C  (high =    +0°C, hyst =   +22°C)   sensor = thermistor
    temp2:     +16.0°C  (high =   +80°C, hyst =   +75°C)   sensor = 3904 transistor 
    Problem is, I'm not sure that the sensor is actually a 3904 transistor! The number's lower, but I was pretty sure that the sensor in the AMD64 is in fact a diode. Also, surely the CPU temp can't actually be that much lower than the SYS temp.
    So, I think your fix succeeds in giving lower temps and that's great in that it will tell your system software that the CPU is not overheating, but I don't think it's the solution to high temp reporting. Anyway, as you say, its a solution for people who can't run with system shutdowns due to bogus high temps.  
    I've been looking at these temp issues with the MSI K8T, and I was thinking the problem was simply a miscalibration. The Winbond sensor chip on my board (maybe the K8N is the same, maybe not) has a sensor temp offset that gets added to the temp coming from the sensor. On the K8T this number is +54C.   Funny number I know, but I've "fixed" the problem while I wait for a real bios fix on the K8T by simply reducing this offset to give me a CPU temp that matches SYS temp when idle. This enables cool'n'quiet fan control to work properly on my system, which is my main practical concern.

    SDK-19605 - disabled Halo ColorPicker with Gumbo skin draws too dark
    SDK-19596 - When you have a single button on an Alert, the left edge looks flatter than the right
    SDK-19585 - Menus compiled with the halo theme in Flex 4 have a different backgroundColor than in Flex 3
    SDK-19665 - Halo List with Gumbo skin doesnt draw the alternating item color all the way to the right edge of the control if VScrollBar is present
    SDK-19651 - odd header rendering issue on Halo DataGrid with Gumbo skin
    QA Notes: The alert layout code was positioning the buttons/text on sub-pixel boundaries if the width or height of the alert was an odd number of pixels. We always snap to pixel boundaries now, but this may cause bitmap compare issues with Alert.

  • Photoshop Touch SDK for iOS Bugs and annoyances

    I've just finished implementing the "Touch" capability in my iOS app. As I can't find anywhere to post bug reports, and this may help others, here's my experience:
    BUGS:
    1. sendImage in psconnection is multiply broken:
    (a) Network communication depends on the PSRawImage C structure. However, that does not take padding into account. This may work for build settings that don't allow structure padding, it certainly doesn't work for my settings.
    (b) Pixmap support is broken. The CGBitmapContext setting (RGB 888) it attempts to use is unsupported and will throw an exception on iOS
    (c) JPEG support is broken - the (required) format byte simply isn't added to the network packet.
    2. The documentation is wrong/incomplete
    (a) It doesn't mention the format byte - you have to find that in the demo programs that don't use psconnection.
    (b) It suggests that messages to the server are acknowledged. If they are, I'd like to know where/how.
    3. The test version of Photoshop  crashes with some (not all) JPEG images:

    A Google search on the crash signature above shows it has previously occurred as a result of corrupt fonts.  However (a) I'd done all the font checking etc as recommended, and (b) this only occurs for JPEGs, not pixmaps.
    Annoyances:
    1. psconnection is a huge memory hog; it creates multiple copies of images and network packets. Be prepared to rewrite if you're dealing with large images.
    2. psconnection is not thread safe. Be prepared to put in locks and inter-thread communication code.
    3. psconnection is iPad only. Be prepared to rewrite to be able to use it on an iPhone
    4. The serial number for the test version of Photoshop as provided on the Adobe site only works for a few hours, then decides that the serial number is invalid.
    Hints:
    The demo programs e.g., transmitimage, do seem to work, as opposed to psconnection. However, they use their own code that doesn't do much in the way of error checking, etc.

    Can we now assume that the touch SDK has been abandonned by Adobe? It's now a year after "should be updated soon", and currently if you try to download the touch SDK from this page you get the Photoshop 3 SDK instead!!!
    I ask as I'm about to remove Touch support from my app; the very few people that use touch are now having problems e.g., timeouts, with the latest version of Photoshop.

  • Bootcamp Version 3.1 --List of bug reports for the Development Team to fix.

    Please create a list of bug fixes for the Development Team to address in the next version of Bootcamp (e.g., 3.2). This thread assumes that all users are presently running Bootcamp 3.1:
    1. Sound should not be muted every time a user reboots a newer MacBook laptop using Windows 7 Ultimate, 64-bit. My sound is always muted when I load Windows 7 Ultimate, and I have to manually turn it on each time.
    2. Left and right clicks on the trackpad should work out of the box using Windows 7 Ultimate, 64-bit. My left click operates a little less than 50 percent of the time -- i.e., I click it and nothing happens. I had to switch to "tap to click" as a workaround, however, I prefer the good old solid left click.
    Please step right up and add to the bug report list so that the developers have a checklist of issues that need to be fixed. When the bug report list has grown to a respectable size, I'll send an official letter to the C.E.O. to facilitate the bug reports reaching the development team.

    FWIW, I don't have the symptoms you describe. So I think before you call a symptom a "bug" I think you should confirm that it is indeed a "bug" and not a configuration, software, or hardware issue caused by something such as incorrect installation, incorrect setup, or any other third party or user caused action.
    Also, FWIW, I don't think this forum is intended to be used as a survey for gathering "bugs". Apple has an official feedback page where they gather user experiences such as yours. I think if you post your "bugs" there they will get faster attention than posting them here in this user-to-user help forum.
