# Contributions Guide
We welcome contributions to the esp-idf project!
## How to Contribute
Contributions to esp-idf - fixing bugs, adding features, adding documentation - are welcome. We accept contributions via [Github Pull Requests](https://help.github.com/articles/about-pull-requests/).
## Before Contributing
Before sending us a Pull Request, please consider this list of points:
* Is the contribution entirely your own work, or already licensed under an Apache License 2.0 compatible Open Source License? If not then we unfortunately cannot accept it.
* Does any new code conform to the esp-idf Style Guide? (Style Guide currently pending).
* Is the code adequately commented for people to understand how it is structured?
* Is there documentation or examples that go with code contributions? [There are additional suggestions for writing good examples in the examples README](examples/README.md).
* Are comments and documentation written in clear English, with no spelling or grammar errors?
* If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)? Are any commits with names like "fixed typo" [squashed into previous commits](http://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/)?
* If you're unsure about any of these points, please open the Pull Request anyhow and then ask us for feedback.
## Pull Request Process
After you open the Pull Request, there will probably be some discussion in the comments field of the request itself.
Once the Pull Request is ready to merge, it will first be merged into our internal git system for in-house automated testing.
If this process passes, it will be merged onto the public github repository.
## Legal Part
Before a contribution can be accepted, you will need to sign our [Contributor Agreement](docs/contributor-agreement.rst). You will be prompted for this automatically as part of the Pull Request process.

config MBEDTLS_SSL_MAX_CONTENT_LEN
int "TLS maximum message content length"
default 16384
range 512 16384
help
Maximum TLS message length (in bytes) supported by mbedTLS.
16384 is the default and this value is required to comply
fully with TLS standards.
However you can set a lower value in order to save RAM. This
is safe if the other end of the connection supports Maximum
Fragment Length Negotiation Extension (max_fragment_length,
see RFC6066) or you know for certain that it will never send a
message longer than a certain number of bytes.
If the value is set too low, symptoms are a failed TLS
handshake or a return value of MBEDTLS_ERR_SSL_INVALID_RECORD
(-0x7200).
config MBEDTLS_DEBUG
bool "Enable mbedTLS debugging"
default "no"
help
Enable mbedTLS debugging functions.
If this option is enabled, use the mbedtls_debug_set_threshold()
and mbedtls_ssl_conf_dbg() functions to obtain debugging output
from mbedTLS.
Note thatm mbedTLS debugging is not related to the ESP logging
functionality. See the "https_request_main" example for a
sample function which connects the two together.

+-------------------------------------------+
Item hash list
~~~~~~~~~~~~~~
To reduce the number of reads performed from flash memory, each member of Page class maintains a list of pairs: (item index; item hash). This list makes searches much quicker. Instead of iterating over all entries, reading them from flash one at a time, ``Page::findItem`` first performs search for item hash in the hash list. This gives the item index within the page, if such an item exists. Due to a hash collision it is possible that a different item will be found. This is handled by falling back to iteration over items in flash.
Each node in hash list contains a 24-bit hash and 8-bit item index. Hash is calculated based on item namespace and key name. CRC32 is used for calculation, result is truncated to 24 bits. To reduce overhead of storing 32-bit entries in a linked list, list is implemented as a doubly-linked list of arrays. Each array holds 29 entries, for the total size of 128 bytes, together with linked list pointers and 32-bit count field. Minimal amount of extra RAM useage per page is therefore 128 bytes, maximum is 640 bytes.
