Description Alex Thurgood 2017-08-10 09:53:14 UTC
Description:
Analysing memory leaks with Instruments.app on MacOS and my LibreOffice master build indicates that there are multiple (literally 1000's) invocations of code for mallocs which appear to be leaked. This might be the reason why accessing the MacAb is so slow...

Steps to Reproduce:
1. Start XCode, then Instruments.app
2. Choose Memory Leak profile tool
3. Select LibreOffice.app in instdir as target process
4. Click on the record button, LODev is started by the profiling tool
5. Wait for the StartCenter to load.
6. Load a previously created MacAb.odb file
7. Click on Tables.
8. Double-click on the MacAb table to open it.
9. Close the table.
10. Close the ODB file.
9. Stop recording.
10. Analyse the profile trace.

Actual Results:  
Multiple instances of memory leaks.

Expected Results:
It shouldn't leak memory.


Reproducible: Always

User Profile Reset: No

Additional Info:
The major leaks occur in :

macabrecord.cxx lines 68-80 (at least 10,072 iterations) :

void MacabRecord::insertAtColumn (CFTypeRef _value, ABPropertyType _type, const sal_Int32 _column)
{
    if(_column < size)
    {
        if(fields[_column] == nullptr)
            fields[_column] = new macabfield;

        fields[_column]->value = _value;
        if (fields[_column]->value)
            CFRetain(fields[_column]->value);
        fields[_column]->type = _type;
    }
}

with :

fields[_column] = new macabfield;

being singled out by the tool as the problematic instruction


Other "leaky" points :

lines 546-563 of macabrecords.cxx (3175 iterations)

and in particular line 560 :             headerNames[0] = new macabfield;


lines 116-133 of macabrecords.cxx (multiple instances of ca. hundreds/thousands of iterations)

and in particular line 124 :         macabfield *_copy = new macabfield;


lines 857-892 of macabrecords.cxx
in particular 

line 860 :   MacabRecord *macabRecord = new MacabRecord(_header->getSize());


line 880 :   propertyValue = ABRecordCopyValue(_abrecord,propertyName);
 

line 885 :  insertPropertyIntoMacabRecord(propertyType, macabRecord, _header, propertyNameString, propertyValue);


line 71 in macabutilities :
CFStringRef ref = CFStringCreateWithCharacters(kCFAllocatorDefault, reinterpret_cast<UniChar const *>(aString.getStr()), aString.getLength());

I'll take a look too, specifically the calls of CFRetain and CFRelease

If I well understood, we don't speak about memory management directly but of the number of owners of an object.
Of course, if there's no more owner, there'll be garbage collecting and the object will be freed.
For your curiosity, you can read from this:
https://developer.apple.com/library/content/documentation/CoreFoundation/Conceptual/CFMemoryMgmt/Concepts/Ownership.html#//apple_ref/doc/uid/20001148-CJBEJBHH

Anyway let's put NEW for the moment.

An interesting read, but one that I only understand in the abstract sense :-/

I'd like to know the leaks which are still there in this part.
Comment 8 Julien Nabet 2017-08-12 16:44:14 UTC
The code comes from https://developer.apple.com/library/content/documentation/DeviceDrivers/Conceptual/HID/workingwith/workingwith.html
which is legacy code.
Here's the beginning of this page:
"This chapter provides step-by-step instructions, including listings of sample code, for accessing a HID class device on older versions of OS X. If you are developing new code for OS X v10.5 or later, you should use the APIs described in Accessing a HID Device.."

Since prerequisite for LO is 10.9 minimum so I suppose it should be converted with the help of this page:
https://developer.apple.com/library/content/documentation/DeviceDrivers/Conceptual/HID/new_api_10_5/tn2187.html#//apple_ref/doc/uid/TP40000970-CH214-SW2

I can't help here but I'm interested in being notified about what's new for this bugtracker so I won't uncc myself of this one :-)

Hi Julien,

I rebuilt master after your changes were made, and am enclosing the memory leak output profile. Some of the previous leaky points seem to have been resolved, but others remain.

Comment 13 Alex Thurgood 2017-08-16 14:13:39 UTC
The biggest seems to be :

Malloc 16 Bytes	328067	< multiple >	5,01 MiB	libmacabdrv1.dylib	connectivity::macab::MacabRecord::copy(int) const


macabfield *MacabRecord::copy(const sal_Int32 i) const
{
    /* Note: copy(i) creates a new macabfield identical to that at
     * location i, whereas get(i) returns a pointer to the macabfield
     * at location i.
     */
    if(i < size)
    {
        macabfield *_copy = new macabfield;
        _copy->type = fields[i]->type;
        _copy->value = fields[i]->value;
        if (_copy->value)
            CFRetain(_copy->value);
        return _copy;
    }

    return nullptr;
}


This gets invoked 360,000 times in all in just the short sequence of usage described originally.
Comment 14 Telesto 2017-08-16 15:07:58 UTC
@Alex
Off-topic (not sure how to contact you), but would you mind to make a few instrument leak trace (I don't have a own build around with source code linked)
1. related to bug 105500. It's starts leaking when creating a shape. And increases when switching back and forward between two shapes.
2. Open Impress -> Cancel or accept the template -> select master Pages tab in the sidebar (again a leak)
3. I also noticed a possible leak related to the Document recovery (when discarding the recovery)

Hmm, testing with 

Version: 6.0.0.0.alpha0+
Build ID: 75539963e621faafdc0d3ef6759cadb2e0a5d9b4
CPU threads: 4; OS: Mac OS X 10.12.6; UI render: default; 
Locale: fr-FR (fr_FR.UTF-8); Calc: group

doesn't seem to show any difference, I still see 300K+ invocations of 

connectivity::macab::MacabRecord::copy(int) const

Note that allocations by themselves are not a problem. The problem is when the allocation is not matched by a free.

I see that MacabRecords::createHeaderForProperty is calling copy(), and then attempting to release the records at the bottom, but without calling 
   CFRelease(_copy->value);
That may be a problem.

I actually think that the macabfield struct should have a destructor, and that destructor should call CFRelease, instead of replicating the logic all over the place.

Also  MacabRecords::createHeaderForProperty should probably be using 
    std::vector<std::unique_ptr<macabfield >>
instead of manually managing stuff.


Also MacabHeader contains a field called "fields" that should really be a
   std::vector<std::unique_ptr<macabfield>>
and MacabHeader does not seem to be releasing anything when it destructs, which is probably a bug.


In general, this whole chunk of code is pretty bad.

I put the value to nullptr, I even tested value != nullptr in copy function, it still crashes at the same location.

I'm stuck here.

Moreover, I noticed that a bunch of files in macab driver but not only in this part (apple remote part too), used carbon.h.
Carbon is deprecated from MacOs 10.8 (the min MacOs version required for LO) see https://developer.apple.com/library/content/releasenotes/General/CarbonCoreDeprecations/index.html

It seems MacOs/ios specific parts need some rewriting. Perhaps an idea for next year GSOC? But first perhaps notify this situation in ESC?

Comment 22 Julien Nabet 2017-08-20 18:48:54 UTC
Alex: do you have some link to explain more precisely how to run LO with XCode?

Indeed I runned make xcode-ide-integration
but in osx, I got libreoffice.xcodeproj	and soffice.xcodeproj
I opened first one and XCode started to index all the files.
But then what to do precisely?
Where's Instruments.app?
How to define target?

(I built with LO on console with enable-dbgutil not from XCode).
Comment 23 Telesto 2017-08-20 18:55:01 UTC
Instruments is a separate application: Spotlight (CMD + Space), type: instruments

Hi Julien,
 
You don't need to build LO with XCode, indeed, I'm not even sure that you can (I managed once a very long time ago, but before the xcode-ide-integration script even existed - however, at the time, and it was completely by chance, I couldn't get any executable to run, so forget building with XCode).

You don't need Xcode to use Instruments.app, but the reason I mention it in my reports is that Xcode includes a menu entry for developer tools that includes Instruments.app. However, as I found out recently, and as Telesto has indicated, you can find and start it directly by just typing Instruments into the Spotlight search function. Once Instruments has started, you can point it to your instdir tree as the target for analysis. Starting the recording (having previously selected the analytical tool of your choice (memory allocation, leaks, time profiling, stack/call tree, etc) will then automatically launch LODev.app in your /instdir, and close LO once you stop recording.

I have to say that it is still a pretty slow process with a debug build, even with 8G RAM and 4 cores. Doing even the simplest of recordings can take 5 minutes or more each time.

Found it, Ctrl + Space gives Spotlight then instruments

I got only 4GB on my Mac from 2011 (i5, 2,5Ghz), hope that just launching Instruments instead of use Instruments from xCode will help :-)

Another option to speed things up a bit is to launch LibreOffice first, attach it as a running proces, and start recording from the start center or something like that. It feels snappier to me. It will give some faulty/broke results at te beginnen of the recording, however.

When searching issues for issues, a normal - optimised - build will do perfectly fine (in my experience). A symbol build is (only) needed for a source code view.

Currently Apple Instruments leak agent crashes on me repeatedly when trying to trace memory leaks with LO master for this bug, so testing impossible.

Dear Alex Thurgood,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
 
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
