Assigning to Scott for updates.

Thanks. Crappy command line parser in chrome_elf. :(

 Issue chromedriver:1619  has been merged into this issue.

-user-data-dir flag is ignored in canary. I guess this is same bug so i didnt file a new bug.

The occurs with a valid path
 --user-data-dir="c:/CanaryDev" --disable-web-security

This has always worked up until this morning.
Admin right does not change a thing.

in Chrome version 57.0.2935.0 Channel: canary
--user-data-dir="..\User Data" - works perfect!

but in 57.0.2937.0, 57.0.2938.0, 57.0.2938.1 - popup error:

---------------------------
Failed To Create Data Directory
---------------------------
Google Chrome cannot read and write to its data directory:

"..\User Data"
---------------------------
ОК   
---------------------------

Sorry. :( It'll work if you specify a path without spaces, and don't use quotes on the command line. A fix is on the way.

Handle spaces and quotes in chrome_elf command line parser

This is the worst sort of procedural stateful goopy code. I followed the
pseudo-code from
http://www.windowsinspired.com/how-a-windows-programs-splits-its-command-line-into-individual-arguments/
and verified against calling CommandLineToArgvW() which is what we're
attempting to emulate here.

Two tests were removed from
InstallStaticTest.GetSwitchValueFromCommandLineTest because I don't
believe they were correct (spaces after the equal sign), but maybe
Ananta can correct me on that.

This should be fixed in tomorrow's Canary (I think it'll be called 57.0.2940.x, but not positive). Sorry for the breakage and delay.

Thanks for the fix, Scott !

Chromedriver windows bot is green again.
https://build.chromium.org/p/chromium.chromedriver/builders/Win7

in new Chrome version 57.0.2942.0 Channel: canary
relative paths - don't work...

in Chrome version 57.0.2935.0 Channel: canary
--user-data-dir="..\UserData" - perfectly worked!

can add or return this opportunity?

Dang. Never considered using a relative dir there as it seems scary. :) But yes, I'll take a look.

in newest Chrome versions  57.0.2944.0, 57.0.2946.0, 57.0.2948.0, 57.0.2949.0
relative paths - don't work...

can return this opportunity?

I just tested at head and 57.0.2953.2 and relative dirs seem to work. Could you be more specific about what's not working if you still have a problem?

Tell me how you've installed version Canaries 57.0.2953.2 ?
If you now upload the maximum version - 57.0.2953.0.
Maximum version 57.0.2953.0 - if now upload.

Oh, sorry, .2 is identical to .0, just built with a different compiler.

in Chrome version 57.0.2953.0 Canary
chrome.exe --user-data-dir="..\UserData" relative paths - don't work...

in Chrome version 57.0.2935.0 Channel: canary
--user-data-dir="..\UserData" - perfectly worked! (just checked)

I'm sorry, I still can't reproduce the failure.

Thank you very much, everything works perfectly!

Can you abort creation of empty dir ?

with command line: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\chrome.exe --user-data-dir="UserData"
Use Directory of: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\UserData
And create empty dir, which not used: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\58.0.3007.0\UserData

need fix: NOT NEED create empty dir: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\58.0.3007.0\UserData

with command line: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\chrome.exe --user-data-dir="..\Application\UserData"
Use Directory of: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\UserData
then create empty dir: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\Application\UserData

need fix: NOT NEED create empty dir, which not used: C:\Users\scott\AppData\Local\Google\Chrome SxS\Application\Application\UserData
