Out of 415 labels throughout the code base, 86 of those labels were
not at the start of the line. Which means labels always at the start of
the line is the favoured style overall with 329 instances.
Out of the 86 labels not at the start of the line:
* 75 were indented with the same indentation level of the following line
* 8 were indented with exactly one space
* 2 were indented with one fewer indentation level then the following
line
* 1 was indented with the indentation level of the following line minus
three space (probably unintentional)

Closes#11134
Linked lists themselves do not carry any allocations, so for the lists
that do not have have a set destructor we can just skip the
Curl_llist_destroy() call and save CPU time.
Closes#10764
- they are mostly pointless in all major jurisdictions
- many big corporations and projects already don't use them
- saves us from pointless churn
- git keeps history for us
- the year range is kept in COPYING
checksrc is updated to allow non-year using copyright statements
Closes#10205
Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.
Closes#8869
To simplify, and also since the returned name is not the full actual
name used for the check. The port number and zone id is also involved,
so just showing the name is misleading.
Closes#8750
1. The function would only ever return CURLE_OK anyway
2. Only one caller actually used the return code
3. Most callers did (void)Curl_disconnect()
Closes#8303
- the data needs to be "line-based" anyway since it's also passed to the
debug callback/application
- it makes infof() work like failf() and consistency is good
- there's an assert that triggers on newlines in the format string
- Also removes a few instances of "..."
- Removes the code that would append "..." to the end of the data *iff*
it was truncated in infof()
Closes#7357
As host names are case insensitive, the use of case sensitive hashing
caused unnecesary cache misses and therefore lost performance. This
lowercases the hash key.

The Curl_easy pointer struct entry in connectdata is now gone. Just
before commit 215db086e0 landed on January 8, 2021 there were 919
references to conn->data.
Closes#6608
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.
- We mostly operate on transfers and not connections.
- We need the transfer handle to log, store data and more. Everything in
libcurl is driven by a transfer (the CURL * in the public API).
- This work clarifies and separates the transfers from the connections
better.
- We should avoid "conn->data". Since individual connections can be used
by many transfers when multiplexing, making sure that conn->data
points to the current and correct transfer at all times is difficult
and has been notoriously error-prone over the years. The goal is to
ultimately remove the conn->data pointer for this reason.
Closes#6425
... and free it as soon as the transfer is done. It removes the extra
alloc when a new size is set with setopt() and reduces memory for unused
easy handles.
In addition: the closure_handle now doesn't use an allocated buffer at
all but the smallest supported size as a stack based one.
Closes#5472
More connection cache accesses are protected by locks.
CONNCACHE_* is a beter prefix for the connection cache lock macros.
Curl_attach_connnection: now called as soon as there's a connection
struct available and before the connection is added to the connection
cache.
Curl_disconnect: now assumes that the connection is already removed from
the connection cache.
Ref: #4915Closes#5009
This makes them never to be considered "the oldest" to be discarded when
reaching the connection cache limit. The reasoning here is that
CONNECT_ONLY is primarily used in combination with using the
connection's socket post connect and since that is used outside of
curl's knowledge we must assume that it is in use until explicitly
closed.

... so that it has a sensible value when ConnectionExists() is called which

Also, make conncache:hashkey() use correct port for bundles that are proxy vs

We use "conn" everywhere to be a pointer to the connection.
Introduces two functions that "attaches" and "detaches" the connection
to and from the transfer.
Going forward, we should favour using "data->conn" (since a transfer
always only has a single connection or none at all) to "conn->data"
(since a connection can have none, one or many transfers associated with
it and updating conn->data to be correct is error prone and a frequent
reason for internal issues).
Closes#3442
Do not assume/store assocation between a given easy handle and the
connection if it can be avoided.
Long-term, the 'conn->data' pointer should probably be removed as it is a
little too error-prone. Still used very widely though.

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

Follow-up to 1b76c38904. The VTLS backends that close down the TLS
layer for a connection still needs a Curl_easy handle for the session_id
cache etc.
Fixes#2764Closes#2771
By masking sure to use the *current* easy handle with extracted
connections from the cache, and make sure to NULLify the ->data pointer
when the connection is put into the cache to make this mistake easier to
detect in the future.

The 'list element' struct now has to be within the data that is being
added to the list. Removes 16.6% (tiny) mallocs from a simple HTTP
transfer. (96 => 80)
Also removed return codes since the llist functions can't fail now.
Test 1300 updated accordingly.
