playlist export: add missing file extension #4531

ronso0 · 2021-11-19T21:59:07Z

original bug https://bugs.launchpad.net/mixxx/+bug/1197302
follow-up https://bugs.launchpad.net/mixxx/+bug/1889352
the fix from #430 got lost somehow.

ronso0 · 2021-11-23T00:37:04Z

@uklotzde Refactored to use regexp in util/string.h

ronso0 · 2021-11-23T17:32:13Z

for anyone testing this without reading the code:
the file dialog behaves unexpectedly, but predictably. this behaviour is caused by QFileDialog itself, not the changes of this PR.

if the current file name has no suffix the selected suffix is not appended
if there IS a 'suffix' it is replaced. Though ANY .-separated segement at the end is replaced

so for example
Birtday-party-15.9.2021
becomes
Birtday-party-15.9.m3u

This has grown way beyond re-applying an old 10-line commit. @Swiftb0y @uklotzde I'll try to wrap my head around your sugestions when I find time. Feel free to finish it.

Swiftb0y · 2021-12-08T23:58:41Z

@ronso0, I took the liberty and pushed my changes directly to your branch so my changes don't get detached from the PR.

ronso0 · 2021-12-09T00:12:10Z

Perfecto, thanks!

Swiftb0y · 2021-12-12T13:37:51Z

src/library/crate/cratefeature.cpp

+const ConfigKey kConfigKeyLastImportExportCrateDirectoryKey(
+        "[Library]", "last_import_export_crate_directory");
+


@uklotzde I'd like to hear your opinion on this. Instead of defining kConfigKeyLastImportExportCrateDirectoryKey in a bunch of cpp files all at once, put it in a header file under the mixxx namespace and then #include it where its needed. Does that make sense, what do you need to specify for it to work? something like inline const ConfigKey ...?

nevermind, its not defined in more than one translation unit. Don't know how I got that idea.

ronso0 · 2021-12-12T13:40:28Z

Now that the cleanup is done I'd prefer to squash the later commits into 0171cc3 and 3d78e2f, so we have 3 instead of 7 commits.
Okay?

Swiftb0y

LGTM, though I'm not sure if I'm allowed to merge since this PR does contain commits I made.

ronso0 · 2021-12-12T18:28:48Z

sqashed, rebased, tested if all commits build.
Ready for final review.

ronso0 · 2021-12-12T18:32:46Z

LGTM, though I'm not sure if I'm allowed to merge since this PR does contain commits I made.

I think it doesn't make a difference if your review proposals are implemented or if you implment them yourself.
@uklotzde could take a final look though.

ronso0 · 2021-12-12T19:22:53Z

pushed again because I squashing wiped your co-authorship @Swiftb0y

src/util/file.cpp

ronso0 · 2021-12-13T20:43:53Z

Btw the overwrite issue @Holzhaus discovered in #4539 occurs here as well.

ronso0 · 2021-12-14T17:31:37Z

The last two commits contain the experimental workaround for the QFileDialog suffix bug (with the Qt dialog).
We could merge filePathWithSelectedExtension() into the new function if there's no spot where we need it without the file dialog.

daschuer · 2021-12-15T12:28:39Z

src/util/file.cpp

+    return fileLocation;
+}
+
+QString checkedFilePathWithSelectedExtension(const QString& caption,


The function name sounds as if it will just do the check. It also pops up a dialog.
This should be expressed by the name.
Something like:
SaveFileDialogWithVerifiedExtension() or such

yes, thank you. consider this WIP and the name will be adjusted.
What I care about here is whether this approach works for everyone, or not.

if this get's sufficient 👍 I'll implement it in other places, too, and change the name.

considering the return value I'd name it filePathWithVerifiedExtensionFromFileDialog

Try to name functions starting with an imperative verb if possible. Like good commit messages ;)

getFilePathWithVerifiedExtensionFromFileDialog ;)

daschuer · 2021-12-15T21:46:55Z

I have tested this and it works quite good. Since the roundtrip happens only in an exceptional case, it is a good solution.

I have noticed if you, misspell the extension, the correctly spelled extension is appended.
I guess that is the expected behavior ...

I think we can merge it after the function name has been adjusted.

daschuer · 2021-12-15T21:48:41Z

@uklotzde Are all your review findings solved.

ronso0 · 2021-12-15T22:17:21Z

I'll address @Swiftb0y's recent comments after implementing the new dialog.

uklotzde

The naming could be improved, but I don't have concerns regarding the code. Merge when ready.

ronso0 · 2021-12-16T22:40:24Z

Okay then, thanks for reviewing!
As usual I'll squash all this back and forth changes into a few easily digestible commits.

ronso0 · 2021-12-17T00:02:01Z

Done. Every commit builds and works as intended.

daschuer

LGTM, Thank you for all these bug fixes of this type. That makes really a difference.

ronso0 · 2022-03-17T19:51:55Z

src/library/baseplaylistfeature.cpp

-    m_pConfig->set(ConfigKey("[Library]", "LastImportExportPlaylistDirectory"),
-            ConfigValue(fileName.dir().absolutePath()));
+    QString fileDirectory(playlistFile);
+    fileDirectory.truncate(playlistFile.lastIndexOf(QDir::separator()));


I suspect this always truncates at position 0, see https://bugs.launchpad.net/bugs/1964508

Native separator is \ on Windows and maybe Qt has already converted the path to use /? In that case lastIndexOf("\") would return -1 which is equivalent to passing 0 to truncate
https://doc.qt.io/qt-5/qstring.html#truncate
It is not recommended to use QDir::separator() for constructing paths, but appearantly it also creates issues when computing paths
