Comment 1

[Magnus Melin [:mkmelin]]

First seen with https://treeherder.mozilla.org/jobs?repo=comm-central&selectedTaskRun=AU2ztcDqRwejlInMd6cr5A.0&revision=62defccbffff4682af81698162b4702ef664f969 but unlikely from that c-c change.
Doesn't fail locally for me, but my m-c is a bit behind.

Comment 2

[Magnus Melin [:mkmelin]]

After updating m-c, this is now 100%reproducible locally. Instead of NS_ERROR_FILE_IS_LOCKED, NS_ERROR_FAILURE is triggered.

Comment 3

[Magnus Melin [:mkmelin]]

Something from https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=b84775bfccf2243f664b1c15ca987a05c54a95e2, likely bug 1348272

Comment 4

[Magnus Melin [:mkmelin]]

Yep. I guess we can't simulate a locked file anymore. https://searchfox.org/comm-central/rev/780a62298b62fe1782812b6fc28ff8a2a7c3be7b/mailnews/base/test/unit/test_compactFailure.js#37-45

Nika, any suggestions for how to simulate? Or is it not possible?

(In reply to Magnus Melin [:mkmelin] from comment #4)

Yep. I guess we can't simulate a locked file anymore. https://searchfox.org/comm-central/rev/780a62298b62fe1782812b6fc28ff8a2a7c3be7b/mailnews/base/test/unit/test_compactFailure.js#37-45

Nika, any suggestions for how to simulate? Or is it not possible?

I can't think of an easy way to mock something like that out without adding the mock locked file implementation in C++, rather than doing it in JS, unfortunately.

Comment 9

[Geoff Lankow (:darktrojan)]

Is it possible to figure out what the file in question is, and actually lock it?

Comment 10

[Magnus Melin [:mkmelin]]

We can get what the folder file is easily, but we can't lock it. I tried opening for writing, but that doesn't cause locking.
