9.0.0 horrendous bug still exists!!!!!!!!!!!

Just reintroducing my pet peeve with Logic in general. It's the one thing that frustrates me most about Logic and it still persists after many many years. Here's my original post from 8.0.2:
http://discussions.apple.com/thread.jspa?threadID=1531297&start=0&tstart=129
The effects and sample caching bug is horrendous in my opinion. It's been there for years. It wastes huge amounts of my time. While there are some things you can do to minimize these glitches, there are NO 100% reliable work arounds. If you work in Logic and want a professional result you absolutely must listen to the finished bounce very carefully for glitches. These glitches come in many forms and will often times only be noticed after you receive the finished product from the mastering house.
The main culprits are:
1. Reverb and delay tails. If you have reverb or delay on a track and you stop playback and move your position, the reverb or delay will begin where it left off.
2. Samples. For example I often replace kicks and snares with samples. When I go to start a bounce random samples will play at the beginning of the track.
3. Clicks from compressor and EQ plug ins. These are less obvious, but generally mastering brings them out loud and clear after it's too late.
Keep in mind that these glitches don't generally happen until a split second before a region starts. That means it is very common for them to happen in the middle of the song. Starting and stopping playback a few times does NOT completely clear the cache.
It's a total craps shoot and the most embarrassing, time wasting aspect of Logic.
I really wish I could trust Logic to give me a bounce that is exactly "as expected."
I just sent a bug report... I encourage you all to do the same. They are obviously working on stuff and I think it's our responsibility to make it a priority for them.

It's an inexcusable bug. It's one of the few reasons left why I can't use it in front of clients. How embarassing to have to trim the beginning of a bounced file to get rid of a reverb tail!
1. If it were truly an AU-only bug, then wouldn't Cubase also exhibit the same behavior? I've not heard of Cubase users complaining about that.
2. If were really an plugin not following the AU spec, then why do these 3rd party plugins pass the validation test?
Since I go way back with this... I can tell you this behavior started with version 4.xx when Emjk adapted Logic to use VST instruments. At that time all of Logic's plugins (reverbs...internal synths) exhibited these problems as well as 3rd party VST. it was a KNOWN issue and had to do with the manner in which Logic handles buffers and and unhooks plugins/AU from the CPU at stop. Plugins, VST & AU become inactive with data in their buffers. It was never a problem with any other DAW as the plugins are kept active long enough to empty the buffers. The onus being put on the plugins was added to the AU spec at a later date to cover Logic's behavior. (which really P.O.'d some plugin developers, so much so that some won't even fix what to them is not their problem.)
I don't know about the latest version of Garageband but interestingly enough, it doesn't exhibit this problem, or if it does, nowhere near as bad as Logic. It was something that was "fixed" in Garageband.
I dislike when companies try and rewrite history, as mentioned, this was a
-known- issue. It was discussed between users and programmers... (back in the day).
over and out on this.

Hi Rohan,
I meant to begin my last post "with all due respect". I read you all the time, you are always well informed, plus you came up with the 8.02 key command fix/discovery..

hi pancentre,
no mate that's not correct re logic flushing the buffer. that is actually my point - it can't, not the way the audio engine is designed - god, but my memory is sketchy on this - i remember getting the ins and outs of this a long time ago...
Right, I understand exactly what you're saying, this is indeed the way Logic works... my point was it's an archaic system that was devised at a time when computers had 1/1000th the processing power we have now. There's no need for such great efficiency, plugins can be kept partially active, this is how 9 out of 10 DAWs flush the buffers, the plugin is always active to some extent.
one of the things that makes logic efficient is the way it handles plugs - it doesn't process them the whole time - only when there is sound to process.
Agreed, see above. I think this is related to a couple of Logic's other quirks.
Efficiency in one area is causing less efficiency in other areas, the overload messages. What happens when a song is playing and it comes upon three regions with a couple of space designers and an instance sculpture? Instead of these plugs being partially active and using a little processor, they all become active at once and often cause a spike... ie; system overload or other kind of glitch.
it is the 3rd party plugs that have to flush its own audio buffer - its not something logic can effect without changing the way it works to become much less efficient.
but if you were to call it a 'logic bug' then i would find it hard to disagree with you:
Well, I guess it's hard to say but it seems like Apple came up with a workaround for Logic's behaviour and then asked everyone else to do the same. Until Apple version 7.xx Logic's plugins used to do the reverb tails and all other manner of little tics & glitches.
There's still a couple of Logic's plugs that aren't all the way compliant.

Index with "or" clause (BUG still exists?)

The change log for 2.3.10 mentions "Fixed a bug that caused incorrect query plans to be generated for predicates that used the "or" operator in conjunction with indexes [#15328]."
But looks like the Bug still exists.
I am listing the steps to-repro. Let me know if i have missed something (or if the bug needs to be fixed)
DATA
dbxml> openContainer test.dbxml
dbxml> getDocuments
2 documents found
dbxml> print
<node><value>a</value></node>
<node><value>b</value></node>
INDEX (just one string equality index on node "value")
dbxml> listIndexes
Index: unique-node-metadata-equality-string for node {http://www.sleepycat.com/2002/dbxml}:name
Index: node-element-equality-string for node {}:value
2 indexes found.
QUERY
setVerbose 2 2
preload test.dbxml
query 'let $temp := fn:compare("test", "test") = 0
let $results := for $i in collection("test.dbxml")
where ($temp or $i/node[value = ("a")])
return $i
return <out>{$temp}{$results}</out>'
When $temp is true i expected the result set to contain both the records, but that was not the case with the index. It works well when there is no index!
Result WITH INDEX
dbxml> print
<out>true<node><value>a</value></node></out>
Result WITHOUT INDEX
dbxml> print
<out>true<node><value>a</value></node><node><value>b</value></node></out>

Hi Vijay,
This is a completely different bug, relating to predicate expressions that do not examine nodes. Please try the following patch, to see if it fixes this bug for you:

Does the "Warning! Not Enough Memory" bug still exist in Logic 8?

Hello everyone,
I'm wondering if the dreaded "warning, not enough memory" bug still exists in Logic 8. Here is a detailed account of the bug from Logic 7: http://discussions.apple.com/thread.jspa?messageID=767597&#767597
If this is fixed, I'm seriously considering upgrading mid-project! The film score I'm working on has many doubling parts that I'd like to edit at the same time in the matrix editor. However, editing multiple parts in the matrix editor seems provoke the little bugger, and I've already been bitten a few times in this project already. The only solution I've found is to stay clear of editing multiple parts at once (i.e. edit each parts individually, which obviously takes more time) or save before editing and hope I dont get bit.
I would LOVE to hear a report that this bug has been exterminated, and perhaps may upgrade mid project if thats the case.
Thanks in advance for your reply!

Heya,
I'm not familiar with the bug you're talking about. But would, as a fellow film composer, strongly urge you against the mid project switch.
I loaded in LP8 and ofcourse had a look at what it was all about, and it's really really fantastic. It also seems very stable. I fortunately have a side project that I am working on so switched to LP8 for that. Whilst I'm thankful to get my head around a very new approach for logic, I'm also thankful that I have this side project as it has illuminated a multitude of problems that exist with LP8 that would make any scoring process a bit of a headache to say the least. The main one being that if you don't have a very very powerful mac (I'm prepping a really fully loaded 8 core) you are not going to get anywhere near the performance out of Logic as you do with 7. This is a bottom up overhaul and it needs hardware to match. Heck even my 30" cinema display seems cramped and insubstantial on this new version. I would be so bold to say hold off until you have a hearty new mac and at least 8.2 is released IMHO but maybe try and get on it onto a smaller project to familiarize yourself before hand.

Old kexi bug still exists?

So I was looking into using something other than phpMyAdmin for editing my databases, so I looked into kexi. When I used the import "Structure and Data" option, it just populates the tables with empty values.
After some searching, I found that this use to be an issue a while back: Problem and Resolution.
Can anyone else confirm this as a still-existing (or reoccurring) bug?
Or, am I just messing something up along the way?
Thanks.

I hope someone can help me... it is very important and i am desperate for answers (BUMP)

PDF From MS Word 2010 Reported Bug Still Exists

I need to create a PDF file today that contains images in a MS Word 2010 document. There is a bug in Acrobat XI Professional that I reported months ago. This bug is still here, and now I need help. Can anyone tell me what I can do to fix this issue?
Here is what happens, and I just reproduced this problem I found awhile back. As I stated, I did report it, but this issue is still here!
I am creating a user guide for software. I insert BMP images that are screen shots. On any page where a BMP image exists within Word, the resulting PDF document does not allow selecting of text in Acrobat Reader XI. The selection goes totally insane and highlights random text through the entire page. This is a software defect for certain.
My question is can I easily fix this with minimal time? I had to fix this last time by removing all images from MS Word and instead pasting the image in Acrobat XI. When I do this, selecting text works. The problem with this bug work-around is that this take lots of time (that I do not have).
Help please???

I found something even better. There is a non Adobe PDF creator on my office computer that correctly creates a PDF. The issue is within PDF creation, because I am using Acrobat Reader XI and selecting text with no problem at all.
I did not have to change a thing other than not use Adobe Acrobat Professional to create the PDF. The software that works correctly where Adobe's own fails is called PDF Xchange Driver by Tracker Software Products LTD.
...and as I already stated, I reported this issue many months ago...

Black lines in landscape content still exist in v.32.4.4 !!

Hi
Adobe should have been fixing this bug in 32.4.4, they did for the Adobe Content viewer.
But this bug still exists in applications made by DPS App Builder ver 32.4.4.
Adobe, please make hot fix URGENT
Thanks
Eli

If you rebuild your app with the option "Enable auto hiding of the vertical folio scroll bar" checked this issue will not appear. Will that not work for your app?
We do plan to release a fix for this on our next scheduled dot release, in approximately a week and a half.

The Bug about 'DB_SECONDARY_BAD' still exists in BerkeleyDB4.8!

The Bug about 'DB_SECONDARY_BAD' still exists in BerkeleyDB4.8?
I'm sorry for my poor English, But I just cannot find anywhere else for help.
Thanks for your patience first!
I'm using BDB4.8 C++ API on Ubuntu 10.04, Linux Kernel 2.6.32-24-generic
$uname -a
$Linux wonpc 2.6.32-24-generic #43-Ubuntu SMP Thu Sep 16 14:17:33 UTC 2010 i686 GNU/Linux
When I update(overwrite) a record in database, I may get a DB_SECONDARY_BAD exception,
What's worse, This case doesn't always occures, it's random. So I think it probably a bug
of BDB, I have seen many issues about DB_SECONDARY_BAD with BDB4.5,4.6...
To reproduce the issue, I make a simplified test program from my real program.
The data to be stroed into database is a class called 'EntryData', It's defined in db_access.h,
where also defines some HighLevel API functions that hide the BDB calls, such as
store_entry_data(), which use EntryData as its argument. The EntryData have a string-type
member-data 'name' and a vector<string>-type mem-data 'labels', So store_entry_data() will
put the real data of EntryData to a contiguous memory block. The get_entry_data() returns
an EntryData builed up from the contiguous memory block fetched from database.
The comlete test program is post following this line:

Use the under command
$ g++ -ldb_cxx -lboost_regex -o test_put test_put.cc db_access.cc directory.cc
to get a test program that can insert a record to database.
To insert a record, use the under command:
$ ./test_put ubuntu linux os
It will store an EntryData named 'ubuntu' and two labels('linux', 'os') to database.
Use the under command
$ g++ -ldb_cxx -lboost_regex -lboost_program_options -o test_update test_update.cc db_access.cc directory.cc
to get a test program that can update the existing records.
To update the record, use the under command:
$ ./test_update ubuntu -r linux -a canonical
It will update the with the key 'ubuntu', with the label 'linux' removed and a new
label 'canonical'.
Great thanks to you if you've read and understood my code!
I've said that the DB_SECONDARY_BAD exception is random. The same operation may cause
exception in one time and may goes well in another time.
As I've test below:
## Lines not started with '$' is the stdout or stderr.
$ ./test_put linux os linus
$ ./test_update linux -r os
Old data| name: linux; labels: os linus
New data| name: linux; labels: linus
$ ./test_update linux -r linus
Old data| name: linux; labels: linus
New data| name: linux; labels:
dbfile_bynam: DB_SECONDARY_BAD: Secondary index inconsistent with primary
Db::put: DB_SECONDARY_BAD: Secondary index inconsistent with primary
terminate called after throwing an instance of 'DbException'
what(): Db::put: DB_SECONDARY_BAD: Secondary index inconsistent with primary
已放弃
Look! I've received a DB_SECONDARY_BAD exception. But thus exception does not always
happen even under the same operation.
For the exception is random, you may have not the "luck" to get it during your test.
So let's insert a record by:
$ ./test_put t
and then give it a great number of labels:
$ for((i = 0; i != 100; ++i)); do ./test_update t -a "label_$i"; done
and then:
$ for((i = 0; i != 100; ++i)); do ./test_update t -r "label_$i"; done
Thus, the DB_SECONDARY_BAD exception is almost certain to happen.
I've been confused by the problem for times. I would appreciate if someone can solve
my problem.
Many thanks!

Bug #18104 still exists

Hello,
I am quite disappointed about BDB 5. One of the most nasty bugs (#18104) still
exists. As soon as you want to use the set_thread_count() feature, BDB will not
free the thread-control-block. If you connect/disconnect, BDB will stop working
quite early. You can re-produce this issue with any `db_*` tool.
The testcase:
#include <stdlib.h>
#include <db.h>
#define DIRECTORY "/tmp/db"
int main()
    /* open environment */
    DB_ENV *handle;
    int status = db_env_create( &handle, 0 );
    status = handle->set_cachesize( handle, 0, 32*1024*1024, 0 );
    status = handle->set_thread_count( handle, 0x100 );
    status = handle->open( handle, DIRECTORY, DB_CREATE, 0644 );
    if( status != 0 )
        return 1;
    /* raise error "Unable to allocate thread control block" */
    for( ;; )
        system( "db_stat -e -h " DIRECTORY " | grep process/thread | wc" );
    return 0;
}

Hi Sandra,
Hi Greg,
Our architecture is quite simple: a cron-job runs ENV->failchk() and ENV->txn_checkpoint()
once a minute (which should be fine, shouldn't it?)
The problem, neither ENV->close() nor ENV->failchk() removes outdated items from the
thread-control-block. One would expect, that the PID is added to the block as soon as the
process connects and removed when the process disconnects. But it is not.
If the block runs out of memory, BDB requires a recovery (see the down below testcase).
Usually ENV->failchk() cleans the thread-control-block, as soon as there are more items in
the block than "thread_count". Today three times it did not even remove them, if there were
more than "thread_count" items in the block - but this happend sporadic so it was difficult
to create a testcase.
Once ENV->failchk() cleans the thread-control-block, BDB works as expected. If a process
connects, the PID is added to the block, and as soon as the process disconnects, the PID is
removed from the thread-control-block. You can test this by looping the first loop 1090 times.
The testcase:
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <db.h>
#include <errno.h>
#define DIRECTORY "/tmp/db"
static int bdb_is_alive( DB_ENV *dbenv, pid_t pid, db_threadid_t tid, u_int32_t flags )
    int status;
    status = kill( pid, 0 );
    if( status != -1 )
        return 1;
    if( errno == ESRCH )
        return 0;
    exit( 1 ); /* should never happen */
int main()
    system( "mkdir -p " DIRECTORY );
    system( "db_recover -h " DIRECTORY );
    system( "rm -rfv " DIRECTORY "/*" );
    /* open environment */
    int status, i;
    DB_ENV *handle;
    status = db_env_create( &handle, 0 );
    status = handle->set_cachesize( handle, 0, 32*1024*1024, 0 );
    status = handle->set_thread_count( handle, 1091 );
    status = handle->set_isalive( handle, bdb_is_alive );
    status = handle->open( handle, DIRECTORY, DB_CREATE, 0644 );
    if( status != 0 )
        return 1;   /* should never happen */
    status = handle->failchk( handle, 0 );
    status = handle->close( handle, 0 );
    /* Now start workers (`db_stat`) + failchks() */
    for( i=0; i < 1089; ++i )       /* thread_count - 2 */
        fprintf(stderr,"Number of items in the thread-control-block: "); fflush(stdout);
        system( "db_stat -e -h " DIRECTORY " | grep process/thread | wc -l" );
        status = db_env_create( &handle, 0 );
        status = handle->set_isalive( handle, bdb_is_alive );
        status = handle->open( handle, DIRECTORY, DB_CREATE, 0644 );
        if( status != 0 )
            return 1;   /* should never happen */
        status = handle->failchk( handle, 0 );      /* strange - does not remove the process-entries created by `db_stat` */
        if( status != 0 )
            return 1;   /* should never happen */
        status = handle->close( handle, 0 );
    /* raise error: "Unable to allocate thread control block" */
    for( i=1; i < 422; ++i )

Camera issue still exists in AIR 16 beta

Just tested my simple camera tester with Air 16 Beta and the issue still exists.
Im refering to the issue were the camera stops responding after a number of attaches/detaches to a video object and if attached multiple calls to setMode.
The issue im referring to is Bug#3850401 - Handle leak with video.attachCamera leading to inoperable camera

Wifi problems still exists?

I sold my gs60 that had an 870m back in january mainly because i couldnt bare the wifi problem. I really loved the laptop and everything about it but everytime my laptop overheated the wifi would drop from 100mb to 1mb or less at times, monday im thinking of buying a new msi laptop and im wondering if these models that are currently being sold on amazon and etc still have the wifi problem or has it been fixed?
And trust me, i read the forums, i read the guides and im pretty decent with computers/software and etc, i uninstalled, reinstalled, updated it, changes adv. settings and even though it improves certain things the problem was still there. So does it still exist?
Or should i just buy a USB wifi?

This problem only occurs in earlier patches of Intel WiFi card of GS60 2Px (8xx series of NVIDIA graphic cards) and not every unit was affected.
If you don't want to take this risk, I'll suggest you buy GS60 2Qx (9xx series of NVIDIA graphic cards).
USB WiFi is a good idea. It certainly has a better signal comparing to the WiFi embedded in the body of the laptop.

Every once in a while when I open my mail or a page I get nothing but strange lines of symbols. Many of the symbols are black triangles with question marks in the center. I completely reset it like new, but problem still exists

Every once in a while when I open my mail or open a page I get lines of strange symbols like black triangles with question marks in the center. I have reset the ipad2 to new condition but the problem still exists.

A reset does not make tthe iPad "like new."
First, let's ensure that we agree on just what is a Reset...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here.

Bug in exists() function of XI Graphical Mapping Tool?

Hi!
If I connect a source field with the exists() function in XI Graphical Mapping Tool and the tag exists it returns TRUE, otherwise it returns FALSE, so everything works as expected.
But I have to connect a user-defined function with exists(). The user-defined function will either calculate a value or set Resultset.SUPPRESS.
If there is a value the exits() function returns TRUE, however if Resultset.SUPPRESS is set it does also return TRUE! This looks to me like a bug in exists() function. Shouldn't it always return FALSE if the input is Resultset.SUPPRESS?
Regards, Tanja

Hi Stefan!
> The exists() function checks, if a queue is empty.
> An empty queue is <b>not</b> represented by the
> SUPPRESS value.
> If inside a queue there is a SUPPRESS value, the
> queue is <b>not</b> empty.
Ok, so it's not a bug and the exists() function is working as expected.
> If you want the exist() function after a UDF, provide
> an empty queue, or easier: return the values "true"
> or "false" directly from the UDF.
Yes, that's how I actually solved the problem. The UDF was used at several places where the ResultList.SUPPRESS output was needed. So I copied the UDF and changed it so that the output was TRUE or FALSE instead.

My IPOD Classic Video 5. Gen. showed videos, but now it does no longer show them, instead i see a black picture on my IPOD and it doesn`t work. I have to restart it every time, i try it. i restore the software with itunes, but the problem still exists.

The Videos are showed up front 4 months, but now they are no longer to be seen. When you star a video first the hard drive starts, but then it stops and hangs up. I have to restart it, starting with the apple logo....

Here is what worked for me:
My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

9.0.0 horrendous bug still exists!!!!!!!!!!!
