Note from weekly bug scrub:
@bryancall raised a concern about performance impact. Because he saw a performance bottleneck with std::string_view
version before.
However, the current implementation of the const char *
version is calling the std::string_view
version internally, as @SolidWallOfCode pointed out.

@masaori335 Can you please assign this to me,I would like to work on this.
@masaori335 is the above issue resolved? If not, I would like to contribute to it.
This is not resolved yet. Thanks for showing interests!
@SunMoon97 I'm really sorry, I just noticed your comment. Still want to work on this? If so, please go a head.
@ShaiviAgarwal2 if @SunMoon97 doesn't want to work on this or no reply for a while, please work on this. I'd also say we have more Good First Issues :) Good First Issue
Okk
Hello. can someone pls explain where can i find the definition of functions std::string_view name_get() const; and std::string_view value_get() const; in the code. I couldn't find the code for them.
Hello. can someone pls explain where can i find the definition of functions std::string_view name_get() const; and std::string_view value_get() const; in the code. I couldn't find the code for them.
The functions std::string_view name_get() const;
and std::string_view value_get() const;
are member functions of the MIMEField
class. The definitions of these functions would be in the corresponding source file (MIME.cc
), which is typically located in the same directory as the header file (MIME.h
).
According to me, name_get()
returns the name of the field, and value_get()
returns the value of the field. Both functions include parameters to return the length of the name or value as an integer.
These functions are defined in the header file for the MIMEField
class
Deprecating the functions means marking them as outdated or no longer recommended for use. It is a way to inform users that these functions may be removed in future versions and should be replaced with the preferred alternatives.
@Manohar-Penta I hope I was able to solve your doubt!! If not, please acknowledge the message
Thanks Shaivi. I was able to find the definitions of the functions. and Are you still working on the issue?? If not can I take over?
Hi, can I tackle this issue?
Should I change char *
version to std::string_view
in all places or adding a warning is enough?
Proposal
Deprecate below two functions of the MIMEField
Background
MIMEField
has twovalue_get
functions returnstd::string_view
andconst char *
.https://github.com/apache/trafficserver/blob/f9aa1e0adb7d23cb9d9dd4fb421b80a24654ae85/proxy/hdrs/MIME.h#L162-L164
Discussion on #10144,
std::string_view value_get() const;
is preferred for error handling and I completely agree with usingstd::string_view
.We can say the same things for
name_get
too. https://github.com/apache/trafficserver/blob/f9aa1e0adb7d23cb9d9dd4fb421b80a24654ae85/proxy/hdrs/MIME.h#L144-L146Concerns
These functions are used widely. The change will be big.
