Settings => mercurial+ => MessageNotUnderstood

[patrik.svestka@…]

When using the snapshot
Smalltalk versionString -> '6.2.5.2095'

WinX64 version.

I'm getting message when just clicking on the Mercurial+ :
[MessageNotUnderstood]: UndefinedObject does not understand: #asFilename in process SettingsDialog [89]

[jan vrany]

Works for me. I need - as always - at least:

• full stack trace (there's Context -> Copy Walkback Text to copy stack trace to clippboard
• Your preferences - %USERPROFILE%\.smalltalk\settings.stc (if it exists, you may want to look at it in text editor to make sure it does not contain anything you consider confidential)

[patrik.svestka@…]

I've attached all the files you have requested.

[jan vrany]

It seems that the problem is that there's no Mercurial installed on your system (or not found in @PATH@. This case was not handled, leading to DNU.

I believe ​0ec4c46/stx.libscm fixes the issue. I cannot test on a real system for I don't have a Windows machine with no Mercurial installed.

Could you try build 2010 (or newer) and confirm?

[patrik.svestka@…]

The Mercurial was not in the PATH. I have tested such a situation - on version '6.2.5.2103' the error message did not appear.

However, if I want to add hg.exe (Mercurial installed at C:\Program Files\Mercurial) via browser button I got the following error:

[HGInvalidExecutableError]: 'hg' executable not configured and not found in standard places! in process SettingsDialog [12]

When there is a directory path, clicking on button browse does not follow the directory (e.g. "C:\Program Files\Mercurial\"), instead it starts from the directory where StX is located.

Fix for issue with DNU when setting the HG command (attempt 1)

[jan vrany]

Ouch, mea culpa.

The above patch should "fix" that (even though this is quite ugly as it interferes
with the system preferences). Could you try it and confirm?

To load it, you may do

Smalltalk fileIn: '/tmp/HGSourceCodeManagementSettingsAppl-doCheckSettings.st'

[patrik.svestka@…]

Thank you for the loading procedure. I was wondering how to load the patch :)).

I confirm that this patch works. It now takes hg.exe and does not produce any errors. I did not yet commit any source code to Mercurial so I have to test the functionality too.

[jan vrany]

Good. I'll commit that fix later together with fix for default path (not to always default to stx workdirectory)

[jan vrany]

Fixed in ​b4c3383/stx.libscm and ​52b1e45/stx.libscm.
Will be included from build 2014 onwards.

[patrik.svestka@…]

It works on build 2015, only the browse button does not work as expected. Still shows the StX directory instead of the path written there.

e.g.
When I have path "C:\Program Files\Mercurial\hg.exe" clicking on browse I expect to be at the directory "C:\Program Files\Mercurial\" not at "C:\prg_sdk\smalltalkx-jv-branch-6.2.5_x86_64-win32\bin\.\ "

[patrik.svestka@…]

When (build 2107) clicking on Mercurial+ settings this warning is displayed:
(probably some index issue?)

Processor [info]: removing invalid read-select fileDescriptor: 5 idx: 2
Processor [info]: removing invalid read-select fileDescriptor: 5 idx: 2

Interesting. Works for me...

This is unrelated. It's a known issue with I/O subsystem, which is rather tricky on Windows (due to rather stupid design of Windows, to put it mildly :) It should not harm, but it's annoying. Perhaps fill in another bug report. But fixing this would be difficult.

[jan vrany]

Update from patrik.svestka@...: another DNU, see stacktrace-issue73-2.txt​​.
This happens on Windows box with no mercurial installed.

This is fixed in ​fe7a227/stx.libscm

[jan vrany]

I have tested this again and also on Windows with no Mercurial installed. It does work for me, so I'm closing this. Please reopen if it still does not work for you (but make sure you have latest stx:libscm :-)
