Notepad++ File Status Auto-Detection not working

@Vitaliy-Dovgan

thank you very much for the hint.

@chcg

If you wouldn’t mind to build one with this flag I would give it a try to see if it resolves the issue.

Cheers

There were 3 changes in the appveyor config:

VM image, as Visual Studio 2013 doesn’t contain vs2015
calling Microsoft Visual Studio 14.0\VC\vcvarsall.bat for vs2015 build
using notepadPlus.vs2015.vcxproj for building the vs2015 version.
couldn’t be avoided. The sourcecode itself is identical and either it is something with the vcxproj for vs2015 which causes the issue or the vcvarsall.bat + the toolset.

Maybe the build of scintilla could also have an influence.

I will do a rebuild with just the toolset changed and using the notepadPlus.vcxproj also for VS2015.

And another one with /Zc:threadSafeInit-

First test is available here:
https://ci.appveyor.com/project/chcg/notepad-plus-plus/build/1.0.117

VS2013 config with PlatformToolset=v140_xp

@chcg

v120 build works, v140 does not.

VS2015 build with /Zc:threadSafeInit- at https://ci.appveyor.com/project/chcg/notepad-plus-plus/build/1.0.118

@chcg

thx, will do the test and report the status later (2-3 hours).

Cheers

@chcg

sorry but additional compiler flag does not work either.

Looks like time to use additional logging then. I mean, logging around file status detection. (I briefly looked at the code, and it’s not obvious at the first glance what exactly can go wrong.)

Vitaliy Dovgan

I’ve found out the cause of the problem. In VS2015, the stupids from Microsoft have broken _wstat for Windows XP! According to a simple change inside the file “PowerEditor\src\ScitillaComponent\Buffer.cpp”:

int st = generic_stat(_fullPathName.c_str(), &buf);
char s[512];
sprintf(s, "Buffer::checkFileState() -> %d, errno %d, FileName \"%S\"", st, errno, _fullPathName.c_str());
writeLog(_T("1.txt"), s);

one can notice that _wstat always returns -1 under Windows XP with errno 22 (EINVAL).
So the fix seems to be to replace _wstat with some native WinAPI function, since we can not rely on VS2015’s CRT anymore.

See https://github.com/joncampbell123/dosbox-x/issues/403 and https://github.com/joncampbell123/dosbox-x/issues/438 which also suffers from this issue. From https://stackoverflow.com/questions/6566978/whats-the-difference-between-struct-stat64-and-struct-stati64-on-win32, maybe we are facing a 64bit issue, see https://msdn.microsoft.com/en-US/library/14h5k7ff.aspx. What happens on using _wstat64.

Vitaliy Dovgan

Yes, it could be that _USE_32BIT_TIME_T needs to be defined for Windows XP. On the other hand, it was reported that defining _USE_32BIT_TIME_T, in its turn, creates problems with std::chrono… Just madness.

Vitaliy Dovgan

Basically, _wstat is used there just to get the file modification time and check if it is read-only or not. There are 2 corresponding WinAPI functions that can be used instead, without being relying on _wstat at all: GetFileTime and GetFileAttributes. Using them, any further breaking change in _wstat will not affect Notepad++ at all!

Vitaliy Dovgan

As far as I understand, an honour to implement the proposed change is mine :) As Notepad++ is the base for all its plugins, I consider such task as quite important. I don’t promise I do it quickly, but I already have an idea what exactly to do. Since _wstat is already called through a macro, the most straightforward change will be to call own function instead of _wstat via the very same macro, providing own structure returned by the function, and the structure will be filled by the WinAPI functions. So the code will remain similar at the surface, but will not rely on _wstat anymore.

Vitaliy Dovgan

OK, guys, I want to make everything in the proper way :) Do you usually create a new git branch to use it for the pull request? Or just directly modify the “master” branch? And is there any possible hints/problems regarding authorization (such as special write rights, SSH, etc.)?

chcg

See https://github.com/notepad-plus-plus/notepad-plus-plus/pulls e.g.
https://github.com/notepad-plus-plus/notepad-plus-plus/pull/4172 made from branch cmeriaux:fix_shortcut_validity. So branching your forked master is the better way, so you could easily pull upstream master again for future work. See also https://github.com/notepad-plus-plus/notepad-plus-plus/blob/master/CONTRIBUTING.md. There shouldn’t be problems regarding auth against your github fork.

chcg

Maybe check this one https://gist.github.com/Chaser324/ce0505fbed06b947d962 regarding git usage with github.

Probably I’m doing something wrong, but here is what I’m getting currently:

git.exe push --progress "origin" feature/file-status-detection-winxp

remote: Permission to notepad-plus-plus/notepad-plus-plus.git denied to d0vgan.
fatal: unable to access 'https://github.com/notepad-plus-plus/notepad-plus-plus.git/': The requested URL returned error: 403

chcg

You can’t push to the repo of donho at https://github.com/notepad-plus-plus/notepad-plus-plus. Do you have a fork of it? Something like https://github.com/chcg/notepad-plus-plus?

Vitaliy Dovgan

That must be it! I did not fork it indeed, just created a branch directly from the https://github.com/notepad-plus-plus/notepad-plus-plus. Will do the fork, thanks.

Vitaliy Dovgan

You know, I realized I absolutely hate the f*ckin’ git, just completely and absolutely.
I’ve created https://github.com/d0vgan/notepad-plus-plus/tree/feature/file-status-detection-winxp and I followed hell of instructions to synchronize it with the main (non-forked) repository. Currently I’m having:

git remote -v
origin  https://github.com/d0vgan/notepad-plus-plus.git (fetch)
origin  https://github.com/d0vgan/notepad-plus-plus.git (push)
upstream        https://github.com/notepad-plus-plus/notepad-plus-plus.git (fetch)
upstream        https://github.com/notepad-plus-plus/notepad-plus-plus.git (push)

And I already tried commands such as (I’m listing them here one by one, but actually I tried them in different order according to what I found in internet):

git fetch upstream
git merge upstream/master
git rebase upstream/master
git rebase master

but still an attempt to create a pull request shows much more changes than I actually made.
I just don’t have any idea what else I need to do to overfight this git madness. It just drives me out of my wits.
