Dear Gilles, Maik and other maintainers
I'm very very very pleased to report that 
digiKam-6.0.0-beta3-20181208T124813-MacOS-x86-64.pkg
does not display this Mac-specific metadata-writing bug.
It was present in all previous versions I tested up to 6.0.0-beta2 of 15th
October.
(I did not test any build of beta3 before 8th Dec.)
Could you please comment on whether this is due to a fix or to chance? Are you
aware of a change in code or in the MacOS build process between beta2 15 Oct
and beta3 8 Dec which may have affected this behaviour?
Thanks very much
Philip

I just did a test by starting up digikam without a digikamrc file and accepting
the default setup options. By default metadata writing is deactivated, but all
the options on the metadata->Advanced tab are selected (so they become active
when metadata writing is turned on).

Not to my knowledge. I set up a test account and started up digikam with a
clean config, just changing the image/sidecar metadata settings.

Did you set a configuration to write comment to ACDSEE XMP namespace ?

digikam.metaengine: Will write Metadata to file
"/Users/test/Pictures/test/image0.jpg"
digikam.metaengine: xmlACDSee "blabla"

Console log showing metadata writing to sidecars.

During this run, the sidecars for 5 images were truncated: image12.jpg, 24, 36,
76, 81. All the other sidecars were correctly written (as far as I can tell).

During that run, metadata was not correctly written to 7 images: image0.jpg, 3,
9, 12, 26, 38, 87. All others were written correctly.

I have run a couple of examples using 100 copies of the same jpg image, i.e.
$ for i in {0..99}; do cp image.jpg test/image$i.jpg; done
I will upload relevant files following this message.

I gave the console error messages in the initial description, but I will upload
a full console log asap. It seems to me that those error messages don't tell us
whether the problem is a bug in Exiv2, or if digikam is providing bad data to
Exiv2 (only occasionally of course). We would need digikam to print out the
data each time it calls Exiv2.

This is a good question. 

The DK implementation is a high level wrapper to preapre metadata to write a
good place. It's Qt code, mostly portable as well..

Al low level operations are managed at end by Exiv2. If the problem become on
access to files, well, this can be an Exiv2 dysfunction.

To investiguate, if you are able to reproduce the problem easily, is to run DK
from a console. The binary is :

/opt/digikam/Applications/KF5/digikam.app/Contents/MacOS/digikam

Just run it and catch all the debug statements printed on the console when
problem occurs.

--- Comment #3 from Philip Tuckey  ---
Thank you for doing that Gilles. I have tested the new version and the
behaviour is the same: occasional errors in writing metadata to image files or
sidecars, when updating many images at once. (I updated the bug title and
component to be more precise.)
Another way to trigger the problem is "Album->Write Metadata to Images", which
is consistent since it rewrites the metadata of all images, and unfortunate as
one wants to use this menu item to clean up the metadata.
This does not seem to be a "straightforward" bug in Exiv2, as the problem does
not occur under linux, it is specific to OS X. The apparently random occurrence
may suggest some kind of overflow error. Is the bug necessarily in Exiv2, could
it be in digikam?
