alacritty: Slow startup after upgrading to 0.13.0.

After upgrading to version 0.13.0 this morning and converting the .yml configuration to .toml, my terminal experiences a delay of about 3 seconds during the initial startup. After the first instance is up, the startup time for subsequent instances is super fast. However, after some minutes, the newly spawned terminal is delayed again, even though there is already a running instance.

$ for i in $(seq 0 10); do time alacritty -e echo; done 2>&1 | grep real
real	0m2.529s
real	0m0.166s

Here is the output of strace -T alacritty -e false, where the poll() operation takes 2.3 seconds: log.txt

@psychon, your patch is good; the delayed startup is gone. Here is the patch that I applied based on your guide:

Could you git checkout 6071a7bf (the last working commit), and then apply this patch:

I’d expect it to fail, and then apply this

Already rebooted; the issue persists. Switched to the old version 0.12.3, and it works perfectly with no delays.

From the original comment:

...
poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}]) <0.000008>
writev(3, [{iov_base="\214\10\2\0[\5\0\0", iov_len=8}], 1) = 8 <0.000009>
poll([{fd=3, events=POLLIN}], 1, -1)    = 1 ([{fd=3, revents=POLLIN}]) <2.334551>
recvmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\1\0\341\0\255\0\0\0!b\0\0!b\0\0\t\0\2\0\20\0\210\0\0\0\0\0\0\0\0\0"..., iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 836 <0.000021>
...

Yay, decoding raw X11 data is always fun. So, the writev(3, [{iov_base="\214\10\2\0[\5\0\0", iov_len=8}], 1) is major opcode \214. Assuming I got my octal right, that’s decimal 140. printf %o\\n 140 in a terminal confirms this.

@hitori1403 Could you run this again and without rebooting, run $ xdpyinfo -queryExtensions | grep opcode? The opcodes are dynamically assigned when the X11 server is starting. For my currently running X11 server, this opcode is from RANDR, which would make a bit of sense.

$ xdpyinfo -queryExtensions | grep 'opcode: 140'
    RANDR  (opcode: 140, base event: 89, base error: 147)

Next, minor opcode is \10, so 8. That would then be a GetScreenResources request, which is known to be sometimes slow.

$ grep ' 8$' /usr/include/xcb/randr.h | grep define
#define XCB_RANDR_GET_SCREEN_RESOURCES 8

The next two bytes are the length of the request (2 four-byte-units) and the root window that the request is sent to (too lazy to decode that and I don’t really care).

So, assuming opcode 140 is RANDR for @hitori1403 , too, this would come from this code: https://github.com/rust-windowing/winit/blob/ca1674519ab3d8df4ce231fe018196a3981c7dea/src/platform_impl/linux/x11/monitor.rs#L355

@hitori1403 Could you also run xrandr --version?:

$ xrandr --version
xrandr program version       1.5.2
Server reports RandR version 1.6

I am asking, because the above code is supposed to be unreachable. RandR 1.3 added a faster way for querying screen information that just queries from the X11 server’s cache and does not have to (slowly) query the hardware again.

Uhm… actually. https://github.com/rust-windowing/winit/blob/ca1674519ab3d8df4ce231fe018196a3981c7dea/src/platform_impl/linux/x11/monitor.rs#L347 This code is fishy. You are telling the X11 server that the newest RandR version you support is version 0.0. I’ll ignore the fact that this does not exist, but the Xorg server might actually listen to this and disable newer features. Or at least it won’t tell you about a newer version than you asked for. https://gitlab.freedesktop.org/xorg/xserver/-/blob/f59871587ea678d4c498874895f4b97687764ee1/randr/rrdispatch.c#L50-59

One of the people here could cook up a patch / experiment to change that randr_query_version(0, 0) to randr_query_version(1, 3) (or whatever version of randr winit actually “hopes for”).

Try 0.12.3 again. This is almost certainly a driver initialization issue.
