Describe the bug
The cefclient sample application crashes unexpectedly when launched using a custom locales path.

To Reproduce
Steps to reproduce the behavior:

Change name of locales directory
Execute: cefclient.exe --locales-dir-path

Expected behavior
The cefclient sample application is started.

Versions (please complete the following information):

OS: Windows 11 Version 23H2 (Build 22631.3880)
CEF Version: 126.2.18

Answer 1 · 2024-07-19T15:33:42.000Z

Are you using a fully qualified path for --locales-dir-path?

Answer 2 · 2024-07-20T10:47:15.000Z

Yes, i use a fully qualified absolute path.

Answer 3 · 2024-07-22T10:06:00.000Z

Using spotify releases I'm pinpointing this as:
05/07/2024 - 125.0.11 69ce47a works correctly
05/10/2024 - 125.0.14 44f7b57 crash
The test is simple:

download/unpack Sample Application
cmd.exe:
cd \Release
rename locales locales2
cefclient --enable-logging=stderr --v=1 --locales-dir-path=%CD%\locales2
Notes.

There are no spaces in path.
Tested on Windows 10 x64 en-US using windows64 flavor.

69ce47a..44f7b57 are just 4 commits, and it is probably when --disable-chrome-runtime was added (hence making chrome runtime default), because 125.0.14 does not crash if --disable-chrome-runtime is passed.
I think kLocalesDirPath is not passed up to chrome, base::PathService::Override(ui::DIR_LOCALES, locales_dir) is called only on alloy implementation.
settings->locales_dir_path is probably set (I didn't modified a build to debug or LOG this), but not passed upstream.

Maybe adding similarily into ChromeMainDelegateCef::PreSandboxStartup a call to InitializeResourceBundle with a similar implementation will fix this. I suppose the DIR_RESOURCES is similarily affected.

Passing --enable-chrome-runtime to 125.0.11 crashes as well. So either this should be patched in Chrome (not recommended), or pair the paths override also in ChromeMainDelegateCef.

I think kLocalesDirPath is not passed up to chrome, base::PathService::Override(ui::DIR_LOCALES, locales_dir) is called only on alloy implementation.

We are setting the override here for Chrome.

Answer 5 · 2024-08-08T17:28:09.000Z

Looks like our ordering is wrong here. The DIR_LOCALES values is queried via the call to ChromeMainDelegate::PreSandboxStartup, which occurs before we've configured it.

The patch doesn't fix problems on linux, another crash with callstack like this:

It looks like Chrome is using base::DIR_ASSETS instead of chrome::DIR_RESOURCES in GetResourcesPakFilePath and LazyInitIcuDataFile. This changed in 2021 (Chromium commit here).

The location of snapshot_blob.bin is also complicated and platform-specific (DIR_EXE on Linux (code), app bundle framework location on MacOS (code)).

One complication with overriding base::DIR_ASSETS on Linux is that we're loading binaries from that directory due to issue #1936 and issue #3213. Currently, base::DIR_ASSETS on Linux is configured to the libcef module path. If we set base::DIR_ASSETS based on the --resources-dir-path value then the location of these binaries will need to change accordingly. Meanwhile, Windows is still using DIR_MODULE (libcef module path) for these DLLs.

We likely want to keep the current binary loading behavior unchanged on Linux.

@JCYang Please explain your use case for customizing the resources-dir-path. Given the complexity described above I'm inclined to just remove this configuration option and require resources to be placed next to the libcef module on Linux and Windows, and in the appropriate app bundle framework location on MacOS.
