Re: case-insensitive filename comparisons
On 9/3/2024 9:13 AM, Rich Draves via Cygwin wrote: I often use grep -r --include. But it has a really annoying problem - the comparison of the filename is case-sensitive. The -i option seems to apply only to the regex not the filename matching. For example, I have many files named virtualenvironment.ini. But unfortunately, sometimes it is virtualEnvironment.ini, VirtualEnvironment.ini, etc. Grep -r --include=virtualenvironment.ini skips the latter files. As a work-around, I use --include="[Vv]irtual[Ee]nvironment.ini" but this is cumbersome and not a complete solution. Because Windows is case-insensitive/case-preserving, I think the Cygwin filename matching should also be case-insensitive. Am I missing something here? Maybe ... Cygwin is trying to act as closely as possible to Posix behavior as it can when running under Windows. AFAIK, Posix does not offer case-insensitive filename matching for grep. While it's more cumbersome, depending on the filenames you desire to match against, you could do something like: grep your-regex $(find . -iname 'virtualenvironment.ini') The -iname operator of find asks it to do a case-insensitive filename match. See also its -ipath and -iregex operators.

On 2/5/2024 8:28 PM, Frank-Ulrich Sommer via Cygwin wrote: Looking at the OpenSSH source code (on Github, not from Cygwin) I found a function "safe_path" that checks that the ownership and access modes for all path components are correct. This relies on "platform_sys_dir_uid" which checks if a UID may own a system directory. The code checks for UID zero and might also accept an OS specific second value (PLATFORM_SYS_DIR_UID) but for Cygwin this seems not to be set. But I don't know where to find the source code for the excat version that is used in Cygwin and I'm unsure about build settings. A comment defines this a safe path as follows: "This is defined as all components of the path to the file must be owned by either the owner of the file or root and no directories must be group or world writable." The "Users" directory is owned by "SYSTEM" (numeric: 18 according to stat) and only writable by Administrators and SYSTEM. The mode cygwin shows for /cygdrive/c/Users is 0750 which should be OK. So my question is: are "Administrators" and "SYSTEM" different users and does cygsshd accept SYSTEM (numeric 18) as a valid user who may own system directories? If the numeric ID is really 18 I can't see how this check can succeed but I'm not sure the code used in Cygwin is the same.

Cygwin's shell (generally bash) will try to pattern match ("glob") the /?
because of the ? . I get intended results if I type:
cmd '/?'
Because what is in the root directory / may vary from system to system,
behavior without the quotes will may vary.

Re: How efficient is 'sleep'?
On 12/15/2023 4:55 PM, Backwoods BC via Cygwin wrote: I have quite a few "service-like" scripts that I put into the background and then have them wake up on a regular basis to do something. I use 'sleep' for the timing of the wakeup periods. My question is: How efficient is 'sleep'? I know of other OSes that just set a timer flag and the process isn't allocated any CPU time until the timer expires. I know that creating a service or even using Task Scheduler are more "proper" ways of doing this, but they are also much more work and would require a significant learning curve as my background is embedded systems, not Windows. I know that my lazy way probably has a penalty, but just how bad is it? Thanks You could strace on it to see what system calls it makes, but I am pretty sure it sets up a timer interrupt and then waits for an event. Very efficient. It does not, for example, continually read the clock until the requested amount of time has passed. The more interesting question is this. If you coded something like: while true; do x; sleep 60; done are you ok with x starting more than 60 seconds apart, because the time to execute x itself, to fork and wait for the processes, etc., gets added into each iteration? If you prefer the invocations of x start at the start of each minute, then you need to calculate, on each iteration, how long to sleep.

Additionally, is there a way to know during runtime the specific extension used by a particular version of Python, without having to make assumptions based on the system type? Cygwin is Unix on Windows, so the dll extension is equivalent to the so extension on Linux/Unix. I am almost sure that we are not modifying the source code for this specific issue. But I could be wrong Allow me to add that Cygwin is not a virtual machine in the sense of WSL (Windows Subsystem for Linux), VirtualBox, etc. Rather, it consists of a dll library that does a pretty good job mapping POSIX library functions to Windows ones, and large collections of programs and libraries that have been ported to the Cygwin environment, including X windows. In any case, this means that it follows Windows linking conventions and object formats. HTH understand why tings are as they are.

Of course, never set that on any system except on a very idle, very I/O bound, well tested process, such as ntpd, that needs stably fast interrupt service and non-preemptible cpu access for ms every few seconds, preferably on a single or few cpus to which affinity is set. Is there anything in /proc which can tell me the current *Windows* scheduler priority level? Or a command line tool? I recall getting taskset going in util-linux a while back, but I don't recall working on priority related things. You could look into the cygwin source code to see how Windows priorities relate to the priority values in Cygwin. Then you may be able just to use /proc/[pid]/stat read out what you want.

This probably has to do with output buffering, and may happen even without

Quote the whole thing if it has spaces or strange characters in it. Alternatively you can use the cygpath program to convert a Windows path to a cygwin one. For example: cygpath -ua 'C:\Users\moss' results in /cygdrive/c/Users/moss Note the quoting to avoid the usual interpretation of \ by the cygwin shell.

On 2/24/2023 1:51 PM, chrstfer via Cygwin wrote: Hi all, First mail, so while I'm fairly sure it's on topic please forgive me if it isn't. Has anyone tried to get a docker container with an X app in it to connect to the cygwin x server? When I run startxwin after starting the wslg container the cygwin Xserver comes in at address (word?) :1 rather than :0, so the two servers can recognize each other (at least to some degree). I can run a cygwin X app in a cygwin console and get an X window, and I can run a wslg app in a wsl bash instance and get an X window, each on their respective servers. But when I set the env DISPLAY in one to the X of the other, it breaks. This isn't just a stupid ask for a redundant use-case, either. The cygwin X server is vastly superior to the wslg one, at least insofar as integration with the windows 10 chrome; cygwin X windows no matter the library will snap like a regular windows window will. Anything coming out of wslg, at least when it comes to gtk3 (emacs-git) and QT4 (qutebrowser), have no native window decorations and don't snap. I've also been unable to find a way to run a docker container as a single X root window (ie to run a DE inside of a container) but I bet if I could connect to the cygwin X server that'd be fairly straightforward. I'll be the first to admit I don't know too much about X so is what I'm asking even possible? (I do mainly use linux, but normally X is one of those things that i dont fiddle with much) UItimately/mostly I'm just fed up of being stuck in Windows windowland at work and not having emacs-git*. At least thats how i landed on this topic, but it seems to me being able to run a docker container and have it hook into a cygwin X server that's already running would be a good feature generally. Especially if it would enable me to disable WSL again. (*As an aside: while I have gotten it to compile, and it runs in the console, so many tests break that I'm afraid to even try compiling it for gtk3; so a docker container of debian stable seemed a logical next step and i half-expected it to just work, to be honest, given how seamless the rest of my cygwin experience has been recently, and I would put money on these two issues being on docker/docker-desktop/wsl, given how poor wslg's integration is despite being a microsoft project) If it's of any help in understanding this, in wsl I set DISPLAY=:0 and can start X apps that connect to the Cygwin X server. I wonder if there are issues trying to run two X servers at the same time ...

Re: [FEEDBACK] Issue with fd_set, FD_ZERO, FD_SET, FD_SETSIZE : Cygwin
Ok ... assuming the "Modern C" is more or less POSIX based and does not use things outside the realm of what cygwin supplies, I think the answer is straightforward: Make sure you install every program and every library that the book uses. There's not really such a thing as a "full install" for Cygwin (and it would huge anyway), so you'll have to figure out what going through the book demands. Fortunately, you can somewhat do that as you go, finding packages that need to be installed.

These functions always need to provide the full file information, even if only a small subset is needed. To determine the 'x'-permission bits in the 'stat.st_mode' field on a 'noacl'-mount, Cygwin reads the first bytes of most files (all except *.exe, *.lnk, *.com). The 'x' bits are set if the file starts with "#!" (script), ":\n" (?) or "MZ" (Windows executable). On 'noacl' mounts, this behavior could be suppressed by 'exec' or 'noexec' mount options. Interesting. I removed the noacl from /etc/fstab and restarted all Cygwin processes. The mount program now shows that drive without noacl. It still takes surprisingly long to ls if I have not done so recently. The directory contains ~1200 files. Further thoughts?

(And maybe improve the rendering of outputs.) My directory /usr/share/fonts/microsoft/ contains 120+ ttf links, though none looking anything like helv*. I doubt it. I'm not familiar with gv, but this looks like you're trying to process documents that incorporate Helvetica, in a way that requires having the font files, without having the font files. Helvetica is a trademark, and the font files are under copyright, so no Cygwin package is going to be able to include the fonts or even include substitutes with matching filenames. You *might* be able to add symlinks from the missing Helvetica files to more readily available metric-identical alternatives you already have access to, e.g. Arial, MS Sans Serif, or Liberation Sans. Otherwise I suspect you need to either avoid processing files that incorporate fonts you don't own, or buy copies of the relevant Helvetica typefaces. Something I might try first is researching how fontconfig can allow you to set up substitutions.

The first few times you run Emacs, it might seem slow to start. This is because it is compiling the elisp libraries that are needed for your init file (usually .emacs). For the same reason, you might see occasional pauses the first time you use a command. But otherwise you should see a noticeable speed-up of Emacs. Actually, I am not seeing that. The setup as provided does the native compilation in deferred mode, which forks asynchronous native code compilation, apparently while continuing to run byte code. When the native code is ready, it is swapped in, replacing the interpreted byte code. So, if your system has multiple cores (like mine) and is not overloaded, you may not see slow down - only eventual speed up. Thank you for this, Ken!

How to get setup to *re*install a package from the command line
Dear Cygwiners - I've not been able to find a way to get setup, when used from the command line, to *re*install an existing package, so as to repair any brokenness. For context, I had my disk get trashed and restored from a cloud backup. However, that tool is not entirely competent about everything, e.g., links. Most programs work ok, but others clearly are not quite right. So I want to try re-installing all installed packages. But there does not seem to be any way to get command line setup to Reinstall something that is already installed, though the GUI tool can certainly do it. I have used cygcheck to get a list of the installed packages and want to do this in a giant batch. I have a lot of packages installed (though not the entire universe!) so using the GUI to select things one at a time would be very tedious. Is the only alternative to do one run uninstalling all the packages, and then another installing them?

Good idea to wait for Corinna. I did a smidge of research, looking through
the Wikipedia page on the POSIX terminal interface. It suggests that this
part was largely borrowed from System-V, so that may explain what we see in
newlib. And looking up the POSIX spec, it says this:
"Special character on input, which is recognized if the ICANON flag is
set. When received, all the bytes waiting to be read are immediately passed to
the process without waiting for a , and the EOF is discarded. Thus,
if there are no bytes waiting (that is, the EOF occurred at the beginning of a
line), a byte count of zero shall be returned from the read(), representing an
end-of-file indication. If ICANON is set, the EOF character shall be discarded
when processed."
This suggests that indeed control-D will need to be typed twice before a
blocking read on a terminal with ICANON will appear to be at eof. I guess we
can consider getchar to be (almost) like a read of size 1, except where read
would return 0, getchar returns -1.
The quoted text above implies that the second control-D will set the
end-of-file indicator. So I agree that it looks like the ifndef should be
removed. And of course, wherever we said control-D, EOF should be implied (it
is normally control-D, but the user can change which character is associated
with the EOF semantics).

If environment variable TERMINFO is set, cygncurses*.dll searches terminfo from TERMINFO. So it is possible if you have chance to set environment variable TERMINFO. Please refer to 'man terminfo' for more detail. I would add that the escape sequences needed to cause the proper editing on the screen depend on the terminal type, and the information for each kind of terminal is in the terminfo folder.

bc is available in Cygwin. Note that Cygwin is not a single thing, but a library that provides a pretty faithful mapping from POSIX library calls to Windows ones, PLUS a large number of packages, individually installable (modulo their dependencies on one another), of Posix compatible tools recompiled for Cygwin (often with patches to make them compile properly under Cygwin). bc is (logically enough) in the bc package.

(presumably with an X environment > already present/running) The method I use at present is not available in later Thunderbirds. Presently I use an External Editor add-on. If I type control-E it fires up a (Windows) emacs and I can edit there, save and exit, and the edited email is back in Thunderbird. But Thunderbird totally changed their add-on technology a few years ago and this addon has never been updated. (It's a pretty simple add-on, but since I know little about Thunderbird's internals I don't know how to recreate it in their new setup.) The notion with emacs-everywhere is to bind some key globally in Windows to invoke it. First I would select stuff into the cut/paste buffer, then invoke emacs-everywhere, and the buffer's contents would appear in emacs. I would edit, exit that pop-up emacs, and the edited text would be in the paste buffer, which I could paste back into Thunderbird. Not quite as seamless as before, but not as bad as explicit cut and paste back and forth. This is soething I do all the time, so minimizing the actions needed is of significant utility (to me, anyway). It does occur to me, however, that if I am willing to run Thunderbird from WSL, this all might work more or less out of the box. But the stumbling block at present is the lack of xdotool that can be invoked by emacsclient to start an emacs-everywhere pop-up window. Unless someone with deeper knowledge of emacs / emacs-everywhere or of X innards can suggest another way to do that.

emacs-everywhere
Dear Cygwiners - I use Thunderbird as my email tool, and in older versions I could arrange to invoke emacs as an external editor, edit my mail, save and exit emacs, and the edited mail would be there in Thunderbird. I have seen recommendations to use emacs-everywhere to get something like this going in more recent Thunderbirds. However, the recommended emacsclient command fails saying it can't find xdotool - which apparently is not available under Cygwin. So ... am I out of luck on this? Or can the technology be hooked up somehow? Or maybe somebody here know an esy (not many keystrokes / mouse actions) way to get stuff from Thunderbird, edit, and get it back into TBird? This is why I am still on Thunderbird 68.12 (!).

The two places are probably on different volumes (loosely, different disks). That requires a physical move, even under Linux. Your volumes seem a bit slow to access - is one perhaps across a slow network? The rates you cite suggest movement of 50Mb/s (50Mb read + 50Mb write = 100Mb overall). For 40 Gb that should take 40Gb / 50Mb = about 820 secs = a little under 14 mins. (When I say your volumes are slow, I speak from the luxury of having a 2Tb solid state drive! Actually, those speeds may be reasonable depending on the nature of your system.) If the two locations are on different drives, there's no real avoiding this.

Re: Does cygwin have an 'autorun' utility/package?
inotify is a POSIX library that would help meet the need. It apparently has not been ported to Cygwin as a regular package, though Windows has the necessary underlying ability. However, this suggests that you can fairly easily build a program to help: https://github.com/thekid/inotify-win It seems to build and work reasonably well. Another angle is this Qt library (though I am not sure if it works under Cygwin): https://doc.qt.io/qt-5/qfilesystemwatcher.html Best - Eliot Moss -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

Ok, here is a small demonstration of the problem.
#include
#include
#include
unsigned __stdcall thread(void* p)
{
unsigned i;
for (i = 0; i < 100; ++i)
system("./a.exe");
return 0;
}
int main()
{
unsigned i;
HANDLE threads[100] = {0};
FILE* f = fopen("a.c", "w");
fprintf(f, "int main() { return 0; }\n");
fclose(f);
system("g++ a.c");
for (i = 0; i < 100; ++i)
threads[i] = CreateThread(0, 0, thread, 0,0,0);
for (i = 0; i < 100; ++i)
WaitForSingleObject(threads[i], -1);
}
Again, Cygwin is designed to provide a POSIX-like interface.
Maybe you should just be using a Windows C compiler?

ExitProcess does not appear to be a POSIX function. Cygwin strives to provide a
POSIX-like interface, not a Windows-like one. However, if ExitProcess is a
Windows
function, there is probably a library you can use to obtain it in Cygwin (maybe
the winsup (Windows support) library).
