Windows 10 WDM 3.8.3

There is no driver download

[eyaler]

can you kindly explain what you mean? it says "Downloading" twice and i see the progress bar. this was fixed for chromium but happens for me now for firefox with 3.8.3

[MarcosBaungartner]

I am having the same problem and I found out that it has something to do with the timestamp in C:\Users\User\.wdm\driver.json. If the timestamp does not contain today's date, the webdriver-manager will re-download the chrome driver for me.

[SergeyPirogov]

@MarcosBaungartner yes, because cache is valid for 1 day

[SergeyPirogov]

From logs above I see

2022-07-31 02:39:51,264 - WDM - INFO - Driver [C:\Users\eyaler\.wdm\drivers\geckodriver\win64\0.31\geckodriver.exe] found in cache

It means that driver is stored in cache

[MarcosBaungartner]

@SergeyPirogov If I open the json and edit the TimeStamp to the current day, the webdriver-manager doesn't redownload the driver and uses the one he already downloaded. Is there a way to configure the manager so it will ignore the TimeStamp?

[SergeyPirogov]

DriverManager constructor have a parameter cache_valid=1, you can set it like 30 or 365

[johnlawsharrison]

I believe the log messages you are seeing are related to the driver manager making get requests to fetch the version string for the current driver.

It seems that when self._version hasn't been set in Driver, then this call is made: https://github.com/SergeyPirogov/webdriver_manager/blob/master/webdriver_manager/core/driver.py#L43-L45

Which, for GeckoDriver delegates down to this:

https://github.com/SergeyPirogov/webdriver_manager/blob/master/webdriver_manager/drivers/firefox.py#L27-L35

Then, if you look at how WDMHttpClient.get is implemented, it always calls show_download_progress which shows the progress bar no matter what type of get request is happening.

https://github.com/SergeyPirogov/webdriver_manager/blob/master/webdriver_manager/core/http.py#L27-L35

So I believe the original poster is seeing a download progress bar related to simply checking the version, rather than installing the whole driver.

With all of that said, there are 2 issues:

1. The logging messages here are definitely a little confusing. My first impression was similar to OP; I thought that WDM was not properly using the cache
2. Shouldn't it be possible to determine Driver._version from the cached driver, rather than reaching out to the internet? This makes running tests offline nearly impossible in my case, because GeckoDriverManager always needs to check for that version string.
