Bug ID: 47816
           Summary: Half Life 2 doesn't download custom/missing files from
                    HTTP server
           Product: Wine
           Version: 4.16
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winsock

This issue is related to Half Life 2 mod Neotokyo (and possibly all other mods,
even Half Life 2 and its derivatives as well).

Multiplayer HL2 servers often serve custom maps and other assets through a
separate http server called "fast download" in order to reduce bandwidth burden
on the game server itself.

When missing a map, or any other asset, the game client (hl2.exe) connects to
that "fast download" server through http and fetches the missing content.

This works on Windows, but not under Wine. I see absolutely no connection
attempt coming from my Linux client. Nothing in Wireshark, so I assume it's not
even getting past the socket level.

Example from nginx http server log of a Windows client Get request:

26/Sep/2019:19:32:31 +0200] "GET /test_fastdl//maps/nt_ballistrade_ctg.bsp.bz2
HTTP/1.1" 200 2768027 "hl2://123.123.123.123:26300" "Half-Life 2"

I suspect this error is related to the problem (see log attached):

warn:winsock:WS2_recv_base  -> ERROR 10035

Ran inside Proton (Valve's redistribution of Wine, version 4.16) with
WINEDEBUG=warn+all %command%.

I'm available for any further information. I would love to help figure this out
but I'm not sure where to start digging myself.

Love you all!

hl2.exe with WINEDEBUG=+winsock

I should have added more information, but this helps avoid cluttering.

This is running on Arch Linux, kernel 5.3.0, 64 bits (the game is 32 bits
architecture).

This has been happening for a long time, so it's probably not a regression.

Game available here: https://store.steampowered.com/app/244630/NEOTOKYO/
although and half life 2 mod might have the same problem anyway.

Here is how to reproduce the issue after installing the game through Steam:
- delete or rename a file in
"(...)/steamapps/common/NEOTOKYO/NeotokyoSource/maps" let's say
nt_ballistrade_ctg.bsp
- join a multiplayer server running that map
- the client should display a progress bar downloading the missing map
- under Wine, the client will return an error saying the map doesn't exist

Attached another log file generated with WINEDEBUG=+winsock.
