ThreadSanitizer only prints 2 frames



For some reason, the callstacks produced by ThreadSanitizer in my log are always exactly two frames (#0, #1). Is there a hidden setting that limits the number of frames?



Regards





When I use it I get all stack frames in error dumps. There's no hidden "two frames only" setting. Could you please provide a Minimal, Complete, and Verifiable example as well as info on what compiler you are using and what exact commandline options you are passing to the compiler, so that we can try to reproduce.?

I have never used this, but I found the documentation. It has an option called "history size" that defaults to two. Maybe this is what you're looking for. github.com/google/sanitizers/wiki/ThreadSanitizerFlags

I'm curious to know if that solved your problem...

To make it short, there was a library in the stack that was not instrumented just starting with frame #2. This seems to cause Tsan to omit the rest of the stack too.



The history setting did not help.



Thanks anyways.

Keycloak server returning user_not_found error when user is already imported with LDAP

Keycloak server returning user_not_found error when user is already imported with LDAP I am currently running a keycloak server as a service in a kubernetes cluster. I can access it perfectly with the initial keycloak admin account and used it to setup a new realm using LDAP for User Federation. The connection and queries seem to work fine as a I can search for Users and they pop up with their correct username, first name, last name and e-mail so all seemed fine. When I then log out and try to log in with a normal user account that exists in the AD and has been imported I just find get the following error: WARN [org.keycloak.events] (default task-8) type=LOGIN_ERROR, realmId=master, clientId=security-admin-console, userId=null, ipAddress=<my ip>, error=user_not_found, auth_method=openid-connect, auth_type=code, redirect_uri=http://myserver.com/auth/admin/master/console/#/realms/MyRealm, code_id=a8ca7f06-dfec-4e6e-8f6b-74eb871f71da, username=myUser So it seems that in some way wh...

PHP parse/syntax errors; and how to solve them?

PHP parse/syntax errors; and how to solve them? Everyone runs into syntax errors. Even experienced programmers make typos. For newcomers it's just part of the learning process. However, it's often easy to interpret error messages such as: PHP Parse error: syntax error, unexpected '{' in index.php on line 20 The unexpected symbol isn't always the real culprit. But the line number gives a rough idea where to start looking. Always look at the code context . The syntax mistake often hides in the mentioned or in previous code lines . Compare your code against syntax examples from the manual. While not every case matches the other. Yet there are some general steps to solve syntax mistakes . This references summarized the common pitfalls: Unexpected T_STRING Unexpected T_VARIABLE Unexpected '$varname' (T_VARIABLE) Unexpected T_CONSTANT_ENCAPSED_STRING Unexpected T_ENCAPSED_AND_WHITESPACE Unexpected $end Unexpected T_FUNCTION… Unexpected { { Unexpected } } Unexpe...

Using generate_series in ecto and passing a value

Using generate_series in ecto and passing a value I am trying to use generate_series in this query to get the number of sales in a time period even with the days that have no sales. I got it working with a hard-coded value but now I need to get all the sales since the contract was created. What I have so far: query = from( c in Contract, join: v in Voucher, on: v.contract_id == c.id, join: s in Sale, on: s.voucher_id == v.id and c.id == ^contract_id, right_join: day in fragment( "select generate_series(current_date - interval '60 day', current_date, '1 day')::date AS d" ), on: day.d == fragment("date(?)", s.date), group_by: day.d, select: %{ number_sales: count(s.id), total_value: sum(s.value), date: day.d }, order_by: [asc: day.d] ) Repo.all(query) |> Enum.map(fn entry -> Map.put(entry, :date, Date.from_erl!(entry.date)) end) With this query I get all the s...
