Hi, this has been backported to 2.4.x branch. It will be part of apache 2.4.42.No date is foreseen at the moment. The release should happen in a couple of months.

Hi, we don't have a fixed schedule for release. 2.4.41 has just been released a few weeks ago.Unless a serious regression is spotted or some security issues discovered, you should not expect a new release before, let say, 3-4 months.If you want to have an idea of the "release rate", have a look at [1].

Hi,Ok, if you have little knowledge of C, no need to try to apply the patch.You would need a compiler, some libraries, set-up the environment, configure, build, install...I'll install a Windows binaries and try your configuration. Should be easy to reproduce.The syntax you have used is correct (Z:/bla/bla/). AFAIK, the internals of httpd (the APR library to be precise) already translate the '/' (Linux style) in '\' (Windows style).My proposal was just based on information taken from Microsoft doc (search for "When opening a volume or removable media drive (for example, a floppy disk drive or flash memory thumb drive), ..." near the end of https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilew). Because, at some point, on Windows, 'CreteFileW()' is called.Just 2 words on the patch.When a configuration file is parsed, when a '<IfFile ...>' directive is found, all lines up to the corresponding </Iffile> are discarded.To do that the function, we call 'apr_stat()' which gives information on a file (size, name, dates...). In the specific case, no information is requested. This is unusual. Usually we ask for size only, or "standard" information.The patch just changes the requirement from "do not return anything" to "return size file only".However, asking for no information *should still work*. The function should tell us that the file exists or not, without any details on the file itself, if found.My point is that using it this way, is unusual. This could hide a corner case (read: bug in the APR underlying library)I've had in my todo list for a long time to setup a test environment for Windows. It could be a good occasion to do it. Or you could try with the supplier of a Windows binary (Steffen from Apache lounge is following closely the project and could be of help). Reproduce the issue with their binaries and report to issue to them as well.Finally, I put back the mailing list in copy, should anyone have an opinion on itCJ Le 23/08/2019 à 14:12, Heather Lotz a écrit :Also, it would be helpful to know the expected syntax to use in <IfFile> once the patch is applied.For instance, does the patch expect <IfFile "/z/files/development/ApacheSmokeSignal.txt">and the purpose of the patch is to execute the code within the <IfFile> tags?Or does the patch expect <IfFile "Z:/files/development/ApacheSmokeSignal.txt">and the patch will allow the code within the <IfFile> tags to execute as it would on a Linux machine?I opened the patch file in Notepad++ but don't understand the contents.------------------------------------------------------------------------ *From:* Heather Lotz <knot22@xxxxxxxxxxx> <mailto:knot22@xxxxxxxxxxx> *Sent:* Friday, August 23, 2019 6:44 AM*To:* Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> <mailto:christophe.jaillet@xxxxxxxxxx>*Subject:* Re: conditionally create a Virtual Host?Hello Christophe - Thank-you for the reply.

Le 23/08/2019 à 05:04, Heather Lotz a écrit :After some more testing, it seems that this syntax - <IfFile "Z:/files/development/ApacheSmokeSignal.txt">is the root cause of Apache not starting when the external storage device, mapped to Z:, is detached from the Windows 10 PC.I tested these variants individually, which are more *nix like - <IfFile "Z/files/development/ApacheSmokeSignal.txt"> <IfFile "/Z/files/development/ApacheSmokeSignal.txt"> <IfFile "/z/files/development/ApacheSmokeSignal.txt">and the behavior is Apache starts whether or not Z: is attached to the PC, so that is a step in the right direction.
