Hoist element message data creation out of loop

closed

COLLABORATOR

We only want to reset the callstack's local data after we are done adding the widget/media element to the message list for each cached function we are running in. Moving the creation of the message data class out of the loop, and saving it to each of the lists, accomplishes this with the bonus of saving some memory use. ## 📚 Context - [x] Bugfix - [ ] Feature - [ ] Refactoring - [ ] Other, please describe: ## 🧠 Description of Changes - Hoist element message data creation out of loop in `save_element_message` - [ ] This is a breaking API change - [x] This is a visible (user-facing) change ## 🧪 Testing Done - [ ] Screenshots included - [x] Added/Updated unit tests - [ ] Added/Updated e2e tests ## 🌐 References _Does this depend on other work, documents, or tickets?_ - **Issue**: Closes #5677

st.altair_chart shows blank axis and chart when provided a datetime domain

open

CONTRIBUTOR

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary Axis shows blank and the chart shows blank for an altair chart when it is passed a datetime domain. Setting a domain for a non-datetime axis works (tried for quantitative, Q). Chart shows up correctly when passed to altair.show() which indicates this may be a bug with Streamlit. ### Reproducible Code Example [](https://issues.streamlitapp.com/?issue=gh-5733) ```Python import altair as alt import pandas as pd import streamlit as st from vega_datasets import data temps = data.seattle_temps() temps = temps[temps.date.dt.hour == 10] startDate = pd.to_datetime("2010-06-01") endDate = pd.to_datetime("2010-06-30") myScale = alt.Scale(domain=[startDate, endDate]) c = ( alt.Chart(temps) .mark_line(clip=True) .encode(x=alt.X("temp:T", scale=myScale), y="temp:Q") ) st.altair_chart(c) ``` ### Steps To Reproduce 1. Run the reproducible code (streamlit run app.py) in with Streamlit 1.15 and see that the chart is blank. 2. Downgrade Streamlit to 1.13 and see that the chart displays as expected. 3. Upgrade to Streamlit 1.14 to see that it does not work in version 1.14 either. ### Expected Behavior We expect that the domain adjusts the st.altair_chart axis when passed the datetime domain and that the data displays correctly. ### Current Behavior The chart and axis is blank. ### Is this a regression? - [X] Yes, this used to work in a previous version. ### Debug info - Streamlit version: 1.15.0 - Python version: 3.10.8 - Operating System: Mac OSX 12.6.1 - Browser: Chrome - Virtual environment: Pipenv ### Additional Information This error was reported by user [xavierc](https://discuss.streamlit.io/u/xavierc) on the Streamlit forums. Thanks xavierc for noticing it! Works in Streamlit 1.13 <img width="471" alt="Screen Shot 2022-11-18 at 10 22 15 AM" src="https://user-images.githubusercontent.com/39609292/202777649-599f8f20-af44-4977-b618-9273e89c236e.png"> Fails in Streamlit >1.14 <img width="486" alt="image" src="https://user-images.githubusercontent.com/39609292/202777758-f5c9196a-a232-4d12-82ff-dfa170d3cd8c.png"> ### Are you willing to submit a PR? - [ ] Yes, I am willing to submit a PR!

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary The content of cells of a plotly table chart containing white spaces disappears after a button inside another tab is clicked. When scrolling through the table or clicking a button in the same tab the text reappears. ### Reproducible Code Example ```Python import plotly.graph_objects as go import streamlit as st fig = go.Figure() fig.add_table( header=dict(values=["Header1", "Header2 with space"]), cells=dict( values=[ ["text with spaces"] * 30, ["text_without_spaces"] * 30, ], ), ) tab1, tab2 = st.tabs(["Tab1", "Tab2"]) tab1.button("Get text back") tab1.plotly_chart(fig) with tab2: st.button("Click on button and text tab 1 disappears") ``` ### Steps To Reproduce 1. Go to Tab2 2. Click the button "Text tab 1 disappears" 3. Go back to Tab1 (the cells containing spaces are empty) 4. Scroll through the table and the text reappears except for the header reappears or click on "Get text back" and the table is also displayed normally ### Expected Behavior Display of the table does not change. ### Current Behavior Text with spaces is missing. <img width="448" alt="grafik" src="https://user-images.githubusercontent.com/115151415/202720421-96ee3e4f-b717-44f0-9dbc-208c1c6a7146.png"> ### Is this a regression? - [x] Yes, this used to work in a previous version. ### Debug info - Streamlit version: 1.15.0 - Python version: 3.10.2 - Operating System: MacOs 13.0.1 - Browser: Chrome - Virtual environment: Poetry - Plotly version: 5.11.0 (Plotly.js v2.16.0) ### Additional Information This issue might be caused by plotly.js, as mentioned [here](https://stackoverflow.com/questions/59672505/plotly-table-not-showing-words-with-space). But as there is a suggested fix in the stackoverflow entry, it might be possible to solve this problem by adapting the way streamlit interacts with the plotly chart.

Teach WebsocketConnection how to wait on an external auth token

closed

COLLABORATOR

## 📚 Context There's currently a race condition that appears when using an external auth token passed to the streamlit web client. The race is between the auth token actually making it to the iframed streamlit app before it attempts to establish a websocket connection. What generally happens is that the first attempt to establish the websocket connection is done without having received the token, which results in a failed connection attempt. The next retry about 500ms later then succeeds (most of the time, although the asynchronous nature of all of this makes it hard to guarantee when the token is received), but both the extra round-trip and notable startup delay are annoying. This PR fixes this problem by adding a new field to the `/st-allowed-message-origins` response body. The `useExternalAuthToken` field (which for now will always be set to `False` in the pure open source world) is used by the client to decide whether to wait for an auth token to be received from the parent frame before attempting to establish a websocket connection to the Streamlit server. If `useExternalAuthToken` is `False`, the client immediately attempts to establish a websocket connection. Otherwise, it waits until a promise resolves to the auth token before proceeding. - What kind of change does this PR introduce? - [x] Bugfix - [x] Feature ## 🧪 Testing Done - [x] Added/Updated unit tests

Script interaction in python tests (prototype)

COLLABORATOR

A mostly working but hacky implementation of forward message parsing, element query and interaction apis, and test script runner apis. One cypress test file replaced. Getting the value of a widget that was interacted with does not work correctly, we will fix it in the full implementation. Probably not worth actually merging in its current state, creating this as a PR primarily to make it trivial to view as a diff and to discuss it.

cache_utils.get_decorator_api_name util

COLLABORATOR

`CacheType.value` is currently implicitly used to store the name of the public API that the CacheType refers to. (That is, `CacheType.MEMO` has the value `"experimental_memo"`.) This isn't documented anywhere, and it's not intuitive. This PR changes that: - `CacheType.value` is now the stringified version of the enum name ("MEMO" and "SINGLETON" instead of "experimental_memo" and "experimental_singleton") - A new function, `get_decorator_api_name`, returns the public API name for the given CacheType

Pandas stylers don't play nicely with `st.cache` and `st.experimental_memo`

open

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary I am building a small Streamlit application that reads data from a csv file and explains a classification model with the SHAP library. I want to visualise my data, so I have the following code: `@st.cache(suppress_st_warning=True) def load_data(): df = pd.read_csv("stage_2_balanced.csv", sep=";").drop(columns=["Unnamed: 0"]) df = df.dropna() # not necessarily needed in this case but good practice to keep # put view inside load data to use cache view = df.sample(frac=1/3).style.apply(highlight_greater_than, threshold=0.5, axis=1) return df, view data, data_view = load_data() f""" Patient data in our dataset:{nl}Red is recurrent patient, blue is non recurrent patient""" st.dataframe(data_view)` This warning started showing up when I added the pandas style view inside the load_data function. I expected it to execute only once so the view does not get updated every time I click a button or enter some text in the app. Streamlit recommends searching for any place where I may be modifying the return values of load_data, but the above snippet is the only place where I'm using them. ### Reproducible Code Example ```Python import streamlit as st import pandas as pd @st.cache(suppress_st_warning=True) def load_data(): df = pd.read_csv("stage_2_balanced.csv", sep=";").drop(columns=["Unnamed: 0"]) df = df.dropna() # not necessarily needed in this case but good practice to keep # put view inside load data to use cache view = df.sample(frac=1/3).style.apply(highlight_greater_than, threshold=0.5, axis=1) return df, view data, data_view = load_data() st.dataframe(data_view) number = st.number_input('Patient index:', min_value=0, value=0, max_value=len(data.index) - 1, step=1) ``` ### Steps To Reproduce 1. Open the Streamlit page 2. Wait for the page to load and select any number from number_input 3. Scroll up to see CachedObjectMutationWarning ### Expected Behavior I would expect no warning to show up, since nothing is being modified outside of load_data ### Current Behavior **In the Streamlit app:** CachedObjectMutationWarning: Return value of load_data() was mutated between runs. By default, Streamlit's cache should be treated as immutable, or it may behave in unexpected ways. You received this warning because Streamlit detected that an object returned by load_data() was mutated outside of load_data(). How to fix this: If you did not mean to mutate that return value: If possible, inspect your code to find and remove that mutation. Otherwise, you could also clone the returned value so you can freely mutate it. If you actually meant to mutate the return value and know the consequences of doing so, annotate the function with @st.cache(allow_output_mutation=True).

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary The error message when DuplicateWidgetID is raised suggests that two widgets of the same type with the same key have been created when this is sometimes not the case. ### Reproducible Code Example ```Python import streamlit as st st.button("Button", key="x") st.checkbox("Checkbox", key="x") ``` ### Steps To Reproduce _No response_ ### Expected Behavior 1. Allow widgets of different type to have the same ID. or 2. An improved error message something like: ``` DuplicateWidgetID: There are multiple widgets (st.button, st.checkbox) with key='x'. To fix this, please make sure that the key argument is unique for each widget you create. ``` ### Current Behavior Error message: ``` DuplicateWidgetID: There are multiple identical st.checkbox widgets with key='x'. To fix this, please make sure that the key argument is unique for each st.checkbox you create. ``` ### Is this a regression? - [ ] Yes, this used to work in a previous version. ### Debug info - Streamlit version: 1.14.1 - Python version: 3.8 - Operating System: Ubuntu 22.04 - Browser: Safari - Virtual environment: None ### Additional Information _No response_ ### Are you willing to submit a PR? - [ ] Yes, I am willing to submit a PR!

More information in our wiki: https://github.com/streamlit/streamlit/wiki/Contributing --> ## 📚 Context These changes should *hopefully* fix test flakiness for the camera_input e2e test. The reason, why flakiness was happening, is because `Take photo` is active even when the video stream from the browser is not ready yet. Unfortunately, the`react-webcam` library is not capable to provide us readiness event, the `onUserMedia` event is fired at the point when the browser had allowed to get video stream (for example when a user clicked `Allow` for the camera permission prompt), but actual video stream starts work after some period of time. So waiting 1 second before clicking `Take photo` button should be enough. - What kind of change does this PR introduce? - [X] Bugfix - [ ] Feature - [ ] Refactoring - [ ] Other, please describe: ## 🧠 Description of Changes - _Add bullet points summarizing your changes here_ - [ ] This is a breaking API change - [ ] This is a visible (user-facing) change **Revised:** _Insert screenshot of your updated UI/code here_ **Current:** _Insert screenshot of existing UI/code here_ ## 🧪 Testing Done - [ ] Screenshots included - [ ] Added/Updated unit tests - [X] Added/Updated e2e tests ## 🌐 References _Does this depend on other work, documents, or tickets?_ - **Issue**: Closes #XXXX --- **Contribution License Agreement** By submitting this pull request you agree that all contributions to this project are made under the Apache 2.0 license.

Custom "Centered" Widths

closed

NONE

_(Note, you don't have to fill out every section here. They're just here for guidance. That said, nicely detailed feature requests are more likely to get eng attention sooner)_ ### Problem There seem to only be 2 options for the width of streamlit pages at the present, those being to center all elements in a column roughly 730px in width (or smaller, if the window is smaller) or to left-align all elements but have them stretch fully across the screen. It would be helpful to be able to change the size of the centered column (either by proportion of the window or pixel count) so that developers can pick the size most well-suited to their content, and to avoid the comically small columns that appear when vieweing sites on widescreen monitors. ### Solution **MVP:** What's the smallest possible solution that would get 80% of the problem out of the way? A setting in the .YAML file/initialization function (`st.set_page_config()` allowing developers to select a proportion of the window that is taken up by "centered" content. **Possible additions:** What are other things that could be added to the MVP over time to make it better? Slider/number input in the menu of the site (where the checkbox for "wide mode") to make it possible for users to control this setting as well? ### Additional context Add any other context or screenshots about the feature request here. For example, did this FR come from https://discuss.streamlit.io or another site? Link the original source here! [https://discuss.streamlit.io/t/custom-streamlit-centered-widths/33040](https://discuss.streamlit.io/t/custom-streamlit-centered-widths/33040); original streamlit forum post about the issue [https://code49-personalwebsite.streamlit.app/](https://code49-personalwebsite.streamlit.app/); my website that I would like to be able to change the width of (just as an example) --- Community voting on feature requests enables the Streamlit team to understand which features are most important to our users. **If you'd like the Streamlit team to prioritize this feature request, please use the 👍 (thumbs up emoji) reaction in response to the initial post.**

## 📚 Context This PR adds a simple CI job that fails unless the `security-assessment-completed` label has been added to the PR. The intention here is to simply ensure that we don't merge PRs without being reminded to go through the security assessment process if the PR warrants it. The vast majority of our PRs likely won't require an in-depth security review, but we do want to make sure that we don't prematurely merge PRs that we should be getting security reviews for just because we forgot about the process. NOTE: This security process is only something that maintainers will need to think about. Open source contributors, of course, may be asked to make changes to their PRs in case that there is a security implication that needs to be addressed, but the security process itself is a process internal to the Streamlit team. - What kind of change does this PR introduce? - [x] Other, please describe: security process additions

- Adds `bokeh`, `viz`, `twemoji`, `Segment`, `react-bootstrap`, and `IPython` to our NOTICES file - (Each new LICENSE file was downloaded directly from its project's Github repo) - Moves the `modified_sys_path` class, which was copied out of IPython, into a new `streamlit.vendor` package, to make it easier to find vendored Python code - Minor update to `append_license.sh` to fix some "infer name" logic This should satisfy the requirements we have with the Snowflake legal team.

Implement the MemorySessionStorage class

closed

COLLABORATOR

## 📚 Context This PR implements `MemorySessionStorage`, which is our first concrete implementation of the `SessionStorage` protocol and under the hood is really just a thin wrapper around `cachetools.TTLCache`. For now, we make it so that an instance of this class holds at most 128 disconnected sessions for at most 5 minutes. This is reasonable while we're only trying to solve the transient disconnect issue (the numbers are actually quite generous for solving this problem), but we leave the `maxsize` and `ttl` parameters configurable in case we later want to save more sessions for a longer period of time. We don't actually use `MemorySessionStorage` yet, that'll be done in a subsequent PR. - What kind of change does this PR introduce? - [x] Feature ## 🧪 Testing Done - [x] Added/Updated unit tests

ignore a file inside `/pages` directory

### Problem At present, every file inside `/pages` is rendered directly onto the webpage. I want to add some `.py` helper file which will contain all frequently used functions. But **it should not be shown on the webpage.** Alter way would be to define the `.py` helper file outside the `/pages` and use relative import, which would make the problem complex and reduce readbility. ### Solution **Preferred solution:** Add special naming for all those files which are to be hidden. E.g, **Files starting with underscore like `_helper.py` will not be rendered.** ### Additional context Screenshot of webpage, that file should not get rendered.

Update components via session_state

open

NONE

### Problem IT seems that the overall code style is to provide a default value to the widget or component. Then, after the first run, the value can be updated via the relevant key in the session_state. Ie. I update` st.session_state["widget_key"]` via a callback. Then the widget will show the updated value This works with widgets. However, it is not clear how to achieve this with components. Components dont change the value, they will be out of sync with the session state. I looked around none of the community components will upate; none of them is able to interact with other widgets via callbacks/ session_State. One widget solved this by having an explicit `value` parameter to update; this works but might not be the "streamlitty" way of doing things. ### Solution Provide a way to pull the new stession_state into the react state upon re-rendering. If this exists, provide documentation or tutorials for this, as I did not manage to get this to work and it seems nobody else did (At least I did not find any example for this). --- Community voting on feature requests enables the Streamlit team to understand which features are most important to our users. **If you'd like the Streamlit team to prioritize this feature request, please use the 👍 (thumbs up emoji) reaction in response to the initial post.**

st.session_state is not preserved during page switch (with workaround)

closed

NONE

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary In a multipage app _sometimes_ `st.session_state` is lost. Working on a test case I see that the same happens in a single page app that uses different page templates. ### Reproducible Code Example ```Python import streamlit as st FIX_BUG=False # <======================= change here if "widget_option" not in st.session_state: st.session_state["widget_option"] = "option1" if FIX_BUG: for k in st.session_state.keys(): st.session_state[k] = st.session_state[k] print("app refreshed") # app is refreshed at every click st.subheader("st.session_state:") st.write(st.session_state) chosen_page = st.radio("Choose a page:", ["PageA", "PageB", "PageC"]) if chosen_page == "PageA": st.header("This is PageA") st.selectbox("Choose an option:", ["option1", "option2", "option3", "option4"], key="widget_option") if chosen_page == "PageB": st.header("This is PageB") st.write("We do nothing here") if chosen_page == "PageC": st.header("This is PageC") st.write("We do nothing here") ``` ### Steps To Reproduce On the top you read `st.session_state`. 1. Leave `FIX_BUG=False` 2. On `PageA` choose any option but the default one "option1". 3. Click on `PageB`, `PageC` and again on `PageA`. You see that the content of `st.session_state` changes. 4. Clicking on `PageA` again the session status is reset and the option is "option1" again. 5. Change `FIX_BUG=True` 6. Click on the pages: the state is now preserved. ### Expected Behavior Already explained. The bug is fixed by copying each `st.session_state` variable on itself: I assume doing so we send them again to the Javascript frontend that will act accordingly. ### Current Behavior Already explained. ### Is this a regression? - [ ] Yes, this used to work in a previous version. ### Debug info - Streamlit version: 1.14.0 - Python version: 3.8.10 - Operating System: Ubuntu 20.04 - Browser: Firefox 106.2, Brave 1.16.76 ### Additional Information _No response_ ### Are you willing to submit a PR? - [ ] Yes, I am willing to submit a PR! --- Community voting on feature requests enables the Streamlit team to understand which features are most important to our users. **If you'd like the Streamlit team to prioritize this feature request, please use the 👍 (thumbs up emoji) reaction in response to the initial post.**

Some call `import numpy as np` such as [st.pyplot](https://docs.streamlit.io/library/api-reference/charts/st.pyplot) while many do not. The standard for us seems to be we do not preface every call with `import streamlit as st` - What kind of change does this PR introduce? - [ ] Bugfix - [ ] Feature - [ ] Refactoring - [x] Other, please describe: Doc improvement request ## 🧠 Description of Changes - Add pydeck import for st.pydeck_chart - Add numpy and pandas imports for st.dataframe, st.table, st.line_chart, st.area_chart, st.bar_chart, st.deck_gl_json_chart - Remove streamlit imports from st.plotly_chart, st.graphviz_chart, - Change `df` to `chart_data` for st.altair_chart and st.vega_lite_chart to be consistent with st.line_chart. - Make random data consistent with st.line_chart for st.altair_chart - [ ] This is a breaking API change - [x] This is a visible (user-facing) change

Change the placement of the help tooltip

closed

NONE

### Problem I know this sounds extremely nitpicky, but it's been bugging me for a while. The label of an input box is on the left, the help tooltip on the right. This works nicely for narrow boxes, but when the input takes the whole screen, most people do not notice the help being there. ### Solution **MVP:** Provide a widget option to display the help tooltip next to the label. ### Additional context This is what I am talking about: most people will read the label to figure out what the box is for, but few will look all the way over to the right to realize there is help available.  --- Community voting on feature requests enables the Streamlit team to understand which features are most important to our users. **If you'd like the Streamlit team to prioritize this feature request, please use the 👍 (thumbs up emoji) reaction in response to the initial post.**

Pytest-friendly Test API

Streamlit is phenomenal. Everyone knows this. This is why [my beautiful science wife](https://www.researchgate.net/profile/Alexis-Pietak) ^{:heart_eyes_cat:} and I are building out our next [open-source multiphysics bioelectricity simulator](https://github.com/betsee/betse) in Streamlit. Streamlit: *yup, it even does bioelectricity.* ## Streamlit Testing: A Chink in the Armour But all is not quite so phenomenal on the testing front. Sadly, Streamlit currently offers *no* official means of testing Streamlit apps from a `pytest` test suite. Technically, there does exist: * **A [third-party `streamlit-mock` package](https://github.com/acschofield/streamlit_mock).** Of course, this package is effectively unmaintained. While we applaud the one lone GitHub user brave enough to star `streamlit-mock`, we are not that user. * **Browser-based automation ala Cyprus and Selenium.** Of course, then *we* would have to develop, debug, and maintain non-trivial end-to-end WebDriver tests renowned for [superficially behaving non-deterministically](https://salmonmode.github.io/2020/05/11/is-selenium-flaky.html) in perpetuity. Grant funding only extends so far. It doesn't extend that far. Which is probably good, because we value our sanity and marital stability. ## streamlit-mock: Visions of a Better Future Nobody should use `streamlit-mock`, because nobody should use unmaintained things. But everybody should be *inspired* by `streamlit-mock` to create something similar that actually works and is well-maintained, because the core conceits behind `streamlit-mock` are sound. To [quote their `README.md`](https://github.com/acschofield/streamlit_mock/blob/main/README.md): > Our simple streamlit application calling a REST API backend grew over time, became not so simple and needed a test suite. We wrote some Selenium tests, but these are tricky to get right and run relatively slowly. This package "mocks" most streamlit class to allow "pytest" to be used for testing. > Goals: > * **Allow tests to be written using pytest** > * **Tests should run quickly** so that multiple edge cases and variants can be tested > * **Tests should be concise and easy to write** > Non-Goals: > * Testing streamlit itself (the package removes all dependnecies on the real streamlitk) > * Testing that the app uses Streamlit correctly (the package fakes input and records outputs) > * To be as complete as an end-to-end Selenium test (Streamlit/web server are out of the loop) Goals seem reasonable. Non-goals seem reasonable, too. We applaud these reasonable things. ## What Do You Want Us to Do About Your Problems, Bro? **Okay.** Let's get down to brass data science tacks. It'd be phenomenal if Streamlit itself offered an official `pytest`-friendly test API – lightly inspired by `streamlit_mock` but actually well-maintained and working. An official `github.com/streamlit/pytest-streamlit` plugin trivially enabling Streamlit apps to be tested under `pytest` would be *especially* phenomenal. `pytest-streamlit` would hypothetically provide support – presumably in the form of one or more `pytest` fixtures – for programmatically running *any* arbitrary Streamlit app as an integration test under a Streamlit mock API. Indeed, we see that [Streamlit itself tests itself with a `pytest` test suite](https://github.com/streamlit/streamlit/blob/develop/lib/tests/streamlit/runtime/scriptrunner/script_runner_test.py). This sorta suggests that the requisite functionality for testing downstream Streamlit apps with `pytest` already exists... *within Streamlit itself*! Shock twist is shocking. :open_mouth: Indeed, we see that [the existing `streamlit/lib/tests/streamlit/runtime/scriptrunner/script_runner_test.py` integration test](https://github.com/streamlit/streamlit/blob/develop/lib/tests/streamlit/runtime/scriptrunner/script_runner_test.py) appears to already be doing most – maybe even all – of the heavy lifting we'd expect from an official `github.com/streamlit/pytest-streamlit` plugin. Copy-and-pasting the deeply nested functionality of `script_runner_test.py` into our own `pytest` test suite justifiably frightens us, however. If something resembling that could be published as a stand-alone API for reuse by the general public, we will happily dance with our Maine Coon cats on the frozen lake outside our cottage in a TikTok video generally regarded as deplorable. ## What We Used to Do No Longer Works, Which Is Sad Previously, we used to exercise our entire Streamlit app with a trivial integration test in our `pytest` test suite resembling: ```python def test_app_lifecycle(capsys) -> None: ''' Integration test exercising the **maximally trivial app lifecycle** (i.e., workflow spinning up, running, and then immediately shutting down this app). Parameters ---------- capsys Builtin fixture object permitting pytest-specific capturing (i.e., hiding) of both standard output and error to be temporarily disabled. ''' # Temporarily disable pytest-specific capturing (i.e., hiding) of both # standard output and error for the duration of this integration test. Why? # Because this test often takes an excessive amount of time and can, # moreover, fail to halt in various edge cases outside our control. # Capturing output unhelpfully obscures these concerns during local testing. with capsys.disabled(): # Defer test-specific imports. # # Note that: # * Importing "hot_bioelectricity_app.main" has the beneficial side # effect of running this Streamlit-based web app to completion. # * Attempting to run this app via the "streamlit run" subcommand does # *NOT* halt as expected, as that subcommand understandably runs the # passed app indefinitely. from hot_bioelectricity_app import main # Immediately return after doing so. return ``` Tragically, that test now fails with a non-human-readable CPython error resembling: ```

`Race condition` when using `experimental_get_query_params` and inputs

open

NONE

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary # A race case happens when: 1. experimental_get_query_params() - This provides KW variables from localhost:8501/?face=details 2. Either `options` is ordered so that `options[0]==face and index=0` or `index=options.index(face)` 3. Given face="details", calling st.selectbox('Face Name', options, index, key='face') returns face_name. 4. Finally, experimental_set_query_params(face=face_name) - This modifies the variable shown in localhost:8501/?face=grid **When the selection changes,** the code is reran and the default (line 2) changes, which triggers another refresh. The observable issue is that line 3 will refresh the page and the selection will be lost. **Why is it a race condition?** It doesn't happen every time. With nothing to slow the code, it often retains the value. If I add 100-200ms from 1-2 print messages, it fails ~50% of the time. **Issue**: The code expects to sync the URL key-value pairs with streamlit inputs. The issue is caused by changing `options` or `index` to set the current value after the page reloads. **Recommendation**: The input variable `index` should not be part of the objects state definition. Alternately, provide a way to dynamically set UI values or better control the flow. My application involves stepping through data that is effectively an infinite graph. I use it for search and recommendation. Since my app is now a collection of demos (datasets) and HTML+CSS interfaces (faces), with variables for clicked item, query, demo, and face. This URL lead interface is important to allow various apps to connect by sending the user around. I also have embedded submit forms. It all ties together with the KW args in the URL defining the initial state. ### Reproducible Code Example ```Python def get_variable(params, title='Face', key='face', options=[]): #params = st.experimental_get_query_params() face_name = params.get(key,'') # print(f'\n[get_variable] {key}={face_name}') face_name = face_name[0] if isinstance(face_name,list) and len(face_name)>0 else face_name face_idx = 0 # face_idx = dict(zip(options, range(len(options)))).get(face_name, 0) # options = sorted(options, key=lambda x: -int(x==face_name)) selection = st.sidebar.selectbox(title, options, index=face_idx, key=f'var_{key}') # print(f'[get_variable] selection={selection}') return selection ``` ### Steps To Reproduce above ### Expected Behavior _No response_ ### Current Behavior _No response_ ### Is this a regression? - [ ] Yes, this used to work in a previous version. ### Debug info - Streamlit version: - Python version: - Operating System: - Browser: - Virtual environment: ### Additional Information _No response_ ### Are you willing to submit a PR? - [ ] Yes, I am willing to submit a PR!

<!-- Before contributing (PLEASE READ!) ⚠️ If your contribution is more than a few lines of code, then prior to starting to code on it please post in the issue saying you want to volunteer, then wait for a positive response. And if there is no issue for it yet, create it first. This helps make sure: 1. Two people aren't working on the same thing 2. This is something Streamlit's maintainers believe should be implemented/fixed 3. Any API, UI, or deeper architectural changes that need to be implemented have been fully thought through by Streamlit's maintainers 4. Your time is well spent! More information in our wiki: https://github.com/streamlit/streamlit/wiki/Contributing --> ## 📚 Context Right now, the current implementation of st.plotly_chart(...,theme="streamlit") doesn't allow overriding properties within a graph; it will always applies streamlit theme to that graph. As a result, it's not very usable for a developer who wants to override the colors or other such specific things but also get Streamlit's layout changes. As a result, this PR is for that.

More information in our wiki: https://github.com/streamlit/streamlit/wiki/Contributing --> ## 📚 Context Thanks @sfc-gh-kbregula for noticing this, I talked to @jrieke and we can just use capital letters column names for `st.map`, this PR does it additionally to your improved error message. Below is @sfc-gh-kbregula original message: I started using our newest Snowpark integration and wrote the code below. ```python df = snowpark_session.sql(""" SELECT * FROM ( VALUES (1, 10), (2, 20), (3, 30), (4, 40) ) AS V1(lat, lot) """) st.map(df) ``` It turned out that the code above doesn't work because Snowpark returns all columns as uppercase. From the exception message, this was not easily discoverable, so I am adding the column names to make the message more user-friendly and actionable. After merging this change, running the above code will result in the message below. ``` Map data must contain a column named 'latitude' or 'lat'. Existing columns: 'LAT', 'LAT' ``` Another issue is whether we should check column names ignoring case, but this will probably need some discussion, so I'm not changing it yet. _Please describe the project or issue background here_ - What kind of change does this PR introduce? - [ ] Bugfix - [x] Feature - [ ] Refactoring - [ ] Other, please describe: ## 🧠 Description of Changes - _Add bullet points summarizing your changes here_ - [ ] This is a breaking API change - [ ] This is a visible (user-facing) change **Revised:** _Insert screenshot of your updated UI/code here_ **Current:** _Insert screenshot of existing UI/code here_ ## 🧪 Testing Done - [ ] Screenshots included - [ ] Added/Updated unit tests - [ ] Added/Updated e2e tests ## 🌐 References _Does this depend on other work, documents, or tickets?_ - **Issue**: Closes #XXXX --- **Contribution License Agreement** By submitting this pull request you agree that all contributions to this project are made under the Apache 2.0 license.

Unify the distance between label and help for different widgets

open

NONE

As an example, for `st.radio` this distance is minimal. But in `st.text_input` `help` is at the right edge of the canvas.  To find each `help`, the user needs to move his eyes around, which is inconvenient. I suggest for **all widgets** either to pin `help` to `label`, or to align the location of `help` on the entire canvas level. In the second variant, perhaps it would be a good idea to place `help` column slightly more right than the longest `label`. --- Community voting on feature requests enables the Streamlit team to understand which features are most important to our users. **If you'd like the Streamlit team to prioritize this feature request, please use the 👍 (thumbs up emoji) reaction in response to the initial post.**

Improve website metadata

open

CONTRIBUTOR

### Problem Streamlit apps are becoming more and more fully fledged web applications. However, the basic website metadata functionalities are still suboptimal, this causes the app to look kind of weird when shared online. ### Solution I would appreciate it if we could specify more [web app manifest](https://developer.mozilla.org/en-US/docs/Web/Manifest) parameters via `streamlit.config.yaml`, so the webpage looks better in search engine results and when shared: - name - short_name - description - author - language - display (default should be standalone) - icons (ideally just a path to an image and Streamlit will convert it to the different required icon formats/sizes) - theme_color (default should be theme.primaryColor) - background_color (default should be theme.backgroundColor) Personally, I really like how the Nuxt.js PWA module does this, for inspiration see https://pwa.nuxtjs.org/meta. This could possibly be added to `streamlit/config.yaml` like this: ``` [server] runOnSave = true [theme] base = "light" primaryColor = "#dc2626" [metadata] name = "My super long app name" short_name = "Short app name" display = "standalone" icon = "./icon.png" ``` --- Community voting on feature requests enables the Streamlit team to understand which features are most important to our users. **If you'd like the Streamlit team to prioritize this feature request, please use the 👍 (thumbs up emoji) reaction in response to the initial post.**

Deploy app with Google App Engine no longer works with 1.14.0

### Checklist - [X] I have searched the [existing issues](https://github.com/streamlit/streamlit/issues) for similar issues. - [X] I added a very descriptive title to this issue. - [X] I have provided sufficient information below to help reproduce this issue. ### Summary tried to deploy an app with this new version in Google App Engine with no luck. The app page only showed “Please wait…”. @vdonato managed to track down the root-cause of the issue, which is that one of my recent changes made things so that the web client always does a healthcheck on the server before trying to establish its websocket connection. Previously, it just attempted to establish the websocket connection without knowing whether the server is healthy. @vdonato is fairly certain that /healthz has actually always been broken in Cloud Run / App Engine (due to the endpoint name being reserved), but it previously wasn’t an obvious issue because it only got pinged if the client lost its websocket connection. At that point, you’d see the same behavior that you’re running into now since the /healthz checks are guaranteed to fail, but it’d only be mildly annoying because a page refresh would fix it. ### Reproducible Code Example _No response_ ### Steps To Reproduce _No response_ ### Expected Behavior _No response_ ### Current Behavior _No response_ ### Is this a regression? - [X] Yes, this used to work in a previous version. ### Debug info - Streamlit version: 1.14.0 ### Additional Information _No response_ ### Are you willing to submit a PR? - [ ] Yes, I am willing to submit a PR!

Add new MockSessionManager class for testing

closed

COLLABORATOR

## 📚 Context Our runtime tests (in this feature branch) currently rely on the `WebsocketSessionManager` implementation, which isn't ideal because we'd rather not have the runtime tests rely on a real/concrete `SessionManager` implementation. This PR changes this so that a new, minimal `MockSessionManager` (which for now looks more or less exactly like `WebsocketSessionManager`, but only because we haven't actually changed the behavior of `WebsocketSessionManager` yet) is used in runtime tests instead. - What kind of change does this PR introduce? - [x] Other, please describe: testing improvements ## 🧪 Testing Done - [x] Added/Updated unit tests

Audit frontend licenses

closed

COLLABORATOR

- `audit_frontend_licenses.py` is a script that examines the license types for all our frontend production dependencies, and exits with an error if any dependency uses an unacceptable license (for example, the GPL license). - This script is run automatically in our `js-tests` CI job, which means CI will fail if we accidentally bring a package with an incompatible license into the codebase. Before merging this PR, we need to have legal sign off on it.
