[Libreoffice-bugs] [Bug 98343] New: FILEOPEN: can't open files in path of more than 260 chars

[b***@bugs.documentfoundation.org]

https://bugs.documentfoundation.org/show_bug.cgi?id=98343

Bug ID: 98343
Summary: FILEOPEN: can't open files in path of more than 260
chars
Product: LibreOffice
Version: 5.0.5.2 release
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: libreoffice-***@lists.freedesktop.org
Reporter: ***@binovo.es

This problem happens double-click on Windows file explorer, and also using the
Open File dialog inside Writer. Tested using a Windows share.

If the file has long enough path (259+ chars?), Writer is unable to open it and
reports a "<wrong_path> does not exist" dialog.

"wrong_path" is the UNC path to the file, but the server name has its first
char removed, seems UNC path building has a bug ¿?

Can reproduce this easily, ask any question you need.

We tested on Windows 7 Pro 64 bits and Windows Server 2012r2 Std 64bits.

Other software are able to open such files?

Maximum Path Length Limitation
In the Windows API (with some exceptions discussed in the following
paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260
characters.

Not sure if LO's bug, for example I can not copy file into directory long path
with Windows Explorer (win7).

This problem happens double-click on Windows file explorer, and also using
the Open File dialog inside Writer. Tested using a Windows share.

Was that the OS Windows explorer dialog, or had you enabled internal
LibreOffice Open/Save dialogs from Tools -> Options -> General: checkbox "Use
LibreOffice Dialogs"

Also, build details for the LibreOffice install? Simply clip from the Help ->
About LibreOffice dialog.

Thanks.

Windows can in fact use PATHs longer than 260 chars, using unicode paths, and
LO is trying to use them (they start with "\\?\"). Problem is first server char
is lost.

Error message shows path starting "\\?\UNC\erver\..." but it is wrong, should
be "\\?\UNC\server\..."

It was the Windows OS explorer dialog, but I tried with LibreOffice dialog as
per your instructions, and the same error appears.

I can see path has one non-ascii char (Ó), maybe that's the problem?. I tested
putting more non-ascii chars in the file name, but the same error remains (no
difference in lost chars in server name)

Thanks

Could you attach error message and write full correct path?

I tried to open this very file with notepad from Windows explorer and works
perfectly (garbage shown though ;) ).

Reproduced using a 6.0 daily build (2017-09-11_06:28:48,
ffeb750163909e15ee0dd2d16f8030bf08e66eae).

It has to be a network share, for local paths it seems to work, right?

I tried reproducing this again, but for some reason now the long path elements
are replaced with an 8.3 shortened version, and the bug doesn't occur. Eg. in a
path similar to comment 8's, "4 PRODUCCIÓN" becomes "4PRODU~1".

Surely this depends on something else as well, I wonder what.

I tried with LibreOffice 5.2 and also with 6.1.3.2 x64, and continue to
reproduce the issue on Windows 2012r2 (dind't test in other systems).

I have tried clicking from Windows file manager and also from LibreOffice's
open dialog.

Windows is Spanish / Spain.
