Summary0036418: External Tools again fail to execute when the external tool is an .app application (+patch attached)
DescriptionWith the latest SVN of Lazarus (62054), external .app bundles no longer execute (related to bug 0036314, but it resurfaced in a slightly different shape).
This is caused by the following line in exttools.pas:

if not ( FilenameIsAbsolute(s) and FileExistsUTF8(s) ) then ...

Under macOS external tools can also be directories (.app bundles).
I've created a patch for this that changes this line to:

if not ( FilenameIsAbsolute(s) and ( FileExistsUTF8(s) {$IFDEF DARWIN}or DirectoryExistsUTF8(s){$ENDIF}) ) then
Steps To ReproduceExecute an external tool that is an .app bundle from the External tools menu.
Note; without the patch in bug 0036417, you cannot select an .app bundle.
Additional InformationLazarus 2.1.0 r62054M FPC 3.3.1 x86_64-darwin-cocoa (beta)
TagsNo tags attached.

0036314 was solved in r62254. Do you mean things worked then but not any more? In that case which revision broke it?

Correct. It worked after the 0036314 fix. But with (one of the) last SVN version it was broken again.

Woops, forgot to answer your second question:
I have no idea with which SVN version it broke.

I frequently update from SVN, maybe once every 2 or 3 weeks.
I just noticed it was broken again when I updated to r62054. (I assume r62254 was a typo?)

The patch is based on r62054.

What I have observed:

1) TFilenameEdit seems to have the "ofFileMustExist" set (preventing the selection of .app bundles, which are directories
2) an if statement throws an error if NOT FileExistsUTF8(s), so the code exits before executing the .app bundle with the "open" statement.

Not sure when or where these changes were implemented, since both seemed to work correctly after the bugfix (0036314).

No, it was not a typo. You can see "r62254" in the relevant issue's "Fixed in Revision" field and you can verify it from the Subversion commit history.
Why did you checkout r62054? Why not just get the latest trunk always? That's what everybody else does. :)

For future referense, you can bisect a guilty revision when you need to:

I did not get 62054 intentionally haha ... I simply did an "svn up" and 62054 is the version it downloaded ... 😞
I just did an svn-up again, and it downloaded 62379 ... strange.
I'll check out what is still relevant today and get back to you! 👍🏻

Just tested this one in Lazarus 2.1.0 r62379M FPC 3.3.1 x86_64-darwin-cocoa (beta), and the problem seems fixed / non-existing in that version.

It seems my user profile will not allow me to close this bug.
As far as I'm concerned it can be closed.
Apologies for the inconvenience.

Resolved. Now you can close it.
